Active Management Area (AMA) Planning Area, is the eighth in a series of nine volumes that comprise the Arizona Water Atlas. The primary objectives in assembling the Atlas are to present an overview of water supply and demand conditions in Arizona, to provide water resource information for planning and resource development purposes and help to identify the needs of communities. The Atlas divides Arizona into seven planning areas (Figure 8.0-1). There is a separate Atlas volume for each planning area, an introductory/executive summary volume and a resource evaluation volume that examines resource sustainability. “Planning areas” are an organizational concept that provide for a regional perspective on supply, demand and water resource issues. A complete discussion of Atlas organization, purpose and scope is found in Volume 1. Also included in Volume 1 is general background information for the state, a description of data sources and methods of analysis for the tables and maps presented in the Atlas, and appendices that provide information on water law, management and programs, and Indian water rights claims and settlements. To the maximum extent possible, the organization and content of this volume of the Atlas mirrors the six other planning areas. However, readers should be aware that the overall scope of this document differs in some important ways. Five AMAs have been designated in the state as requiring specific, mandatory management practices to preserve and protect groundwater supplies for the future. Four AMAs - Phoenix, Pinal, Prescott and Tucson - were established in 1980 upon enactment of the Groundwater Code (Code) (A.R.S. §§ 45-401 et seq.). In 1994, the Arizona legislature established the Santa Cruz AMA, which had previously been the southeast portion of the Tucson AMA. This legislation recognized the international water management issues facing this area, and that its hydrology required coordinated management of surface water and groundwater. The AMAs include the state’s most urbanized areas, and water use is subject to an extensive regulatory framework. As a result, water supply and demand data within AMAs is often more detailed and comprehensive than outside the AMAs, and unique legal and regulatory complexities exist. By adhering to the standardized Atlas format, Volume 8 provides an important overview of the AMAs and allows for direct comparison with the rest of the state. However, this volume does not include extensive data analysis, nor is it intended to be a comprehensive compilation of information relevant to the AMAs. This volume of the Atlas is the first document of a larger AMA planning effort that includes the AMA Assessment and the fourth management plan for each AMA. The AMA Assessment includes a compilation of historic data, including detailed water budgets; future scenario development; and issue identification, notably issues related to achievement of the statutory management goals for each AMA. The AMA Assessment is intended to provide an analytical foundation for the Section 8.0 Overview DRAFT 1 Arizona Water Atlas Volume 8 2 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 development and promulgation of Fourth Management Plans (A.R.S. §§ 45-561 et seq.). The Management Plans include mandatory regulatory provisions that apply to each water use sector within an AMA. These provisions do not apply to tribal users. There are additional, more detailed data available to those presented in this volume. These data may be obtained by contacting the Arizona Department of Water Resources (Department). 8.0 Overview of the AMA Planning Area The AMA Planning Area is composed of five groundwater basins located in the central and south central parts of the state. The AMAs were established pursuant to the 1980 Groundwater Management Act. The basins are designated as the Santa Cruz AMA, the Tucson AMA, the Pinal AMA, the Phoenix AMA, and the Prescott AMA. The AMAs are located in portions of Santa Cruz, Pima, Pinal, and Maricopa counties as well as the central portion of Yavapai County. There are seven Indian reservations within the planning area including the Tohono O’odham Nation (consisting of three reservations in the planning area), Pascua Yaqui Tribe, Ak-Chin Indian Community, Gila River Indian Community, Fort McDowell Yavapai Nation, Salt River PimaMaricopa Indian Community, and the Yavapai-Prescott Indian Tribe. In 2006, just over 80% of the state’s 6.2 million inhabitants lived in the planning area. In 2003, AMA populations ranged from approximately 38,000 residents in the Santa Cruz AMA to over 3,400,000 residents in the Phoenix AMA. The Arizona Department of Economic Security (DES) estimates that the state’s population will likely double by 2050 to over 12 million people. The majority of this growth will occur in the AMA Planning Area. Between 2001-2003 an average of 3.7 million acre-feet (maf) of water was used annually in the planning area for agricultural, municipal and industrial purposes (including Indian water demands). Of this total demand, approximately 45% was met with groundwater supplies, 30% was met with Central Arizona Project (CAP) water, 20% was met with surface water and 5% was met with effluent or reclaimed water. Agriculture is the largest use sector in the planning area with an average annual demand of approximately 2.2 maf or 60% of the total planning area demand. Municipal sector demand is about 1.3 maf (34%) and industrial sector demand is about 0.23 maf (6%). 8.0.1 Geography The AMA Planning Area covers approximately 14,700 square miles and stretches continuously from the international border through central Arizona to the northern boundary of Maricopa County. The most northern AMA, the Prescott AMA, is discontiguous from the other four AMAs (Figure 8.0-2). The Prescott AMA is within the boundaries of the Central Highlands Planning Area, which borders the Phoenix AMA on the north. The planning area is located between the Southeastern Arizona Planning Area on the east and the Lower Colorado River Planning Area on the west and includes portions of six watersheds, which are discussed in section 8.0-2, Surface Water Hydrology. Most of the AMA Planning Area is located in the Basin and Range physiographic province, which Section 8.0 Overview DRAFT 3 Arizona Water Atlas Volume 8 4 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 is characterized by broad, gently sloping alluvial basins separated by north to northwest trending faultblock mountains. The Prescott AMA and a small portion of the Phoenix AMA lie within the Central Highlands transition zone, which is characterized by a narrow band of mountains of igneous, metamorphic, and sedimentary rocks (Figure 8.0-3). Because of its geographic extent and location in the state, the planning area exhibits a wide range of geographic features, from low elevation, broad, semi-arid Sonoran desert valleys to mountain ranges with summits over 9,000 feet. The topographic variability results in broad variations in the amount of precipitation, temperature range and vegetation type. At approximately 485 square miles in area, the Prescott AMA is the smallest Figure 8.0-3 Arizona physiographic provinces AMA basin and has the highest average elevation. Elevations range from 4,400 feet in the valleys to approximately 7,800 feet in the Bradshaw Mountains. The AMA is characterized by rolling topography, broad sloping alluvial basins and fault block mountains (see Figure 8.3-1). Surface drainages are primarily ephemeral or intermittent. The Santa Cruz AMA is approximately 716 square miles in area and is the southernmost AMA. It lies adjacent to the international border and its major drainage, the Santa Cruz River, flows from Mexico into the basin. The AMA is characterized by the relatively narrow river drainage flanked by hills and higher elevation mountains on its northern, eastern and western boundaries. Elevations range from 3,000 feet where the Santa Cruz River exits the basin to over 9,400 feet in the Santa Rita Mountains (see Figure 8.4-1). North and west of the Santa Cruz AMA, the Tucson AMA is approximately 3,866 square miles in area with two major, parallel alluvial valleys, the Upper Santa Cruz in the east and the Avra and Altar Valleys in the west. High elevation mountain ranges form the eastern and southern borders of the AMA. These “sky islands” are relatively isolated ranges separated by valleys that are part of a unique complex of mountain ranges that are also found in northern Mexico and New Mexico (Warshall, 2006). The Santa Cruz River drains the Upper Santa Cruz Valley and is the major drainage in the AMA. The Tucson AMA has the widest elevational range of any of the AMAs with elevations ranging from 1,770 feet north of Picacho Peak, to over 9,400 feet in the Santa Rita Mountains (see Figure 8.5-1). Section 8.0 Overview DRAFT 5 Arizona Water Atlas Volume 8 The Pinal AMA is located to the north and west of the Tucson AMA, and at 4,100 square miles in area is the second largest basin in the planning area. It is characterized by broad, alluvial Sonoran desert valleys and mid-elevation north to northwest trending fault-block mountains. The AMA is semi-arid with average precipitation of less than 8 inches a year in most of the basin. The Gila River flows east to west in the northern part of the basin while the Santa Cruz River enters the basin from the southeast, flowing primarily ephemerally toward the northwest. Elevations range from about 1,000 feet where the Gila River and Santa Cruz River exit the basin in the northwest to over 6,800 feet at Kitt Peak at the southern basin boundary (see Figure 8.2-1). The Phoenix AMA is the largest AMA basin at approximately 5,646 square miles and is characterized by Sonoran desert valleys that are generally from 1,000 to 2,500 feet above mean sea level, surrounded by mid-elevation mountain ranges. The basin is drained by five major rivers, the Salt, Gila, Verde, Agua Fria and the Hassayampa. While the basin is semi-arid, generally receiving less than eight inches of precipitation a year, the state’s most important water producing watersheds, the Salt and the Verde, converge in the Phoenix AMA, representing an important water supply for the area. Elevation ranges from 755 feet where the Gila River exits the basin to almost 5,900 feet in the New River Mountains on the northern basin boundary (see Figure 8.1-1). 8.0.2 Hydrology1 Groundwater Hydrology With the exception of the Prescott AMA, a large portion of the AMA planning area is located in what Anderson, et al. (1992) categorized as the Central basins. Stream alluvial deposits and upper basin fill are the principal water bearing sediments in these basins. The Central basins are characterized by small to moderate amounts of mountain-front recharge, streamflow infiltration and significant underflow in and out of the basins. Groundwater flows tend to move inward from the edges of the basin and higher elevations and then downstream towards the outflow portion of the basin. The Prescott AMA is located in what Anderson, et al. (1992) categorized as the Highland basins. Highland basins consist of basin fill and alluvium deposits, similar to the Central basins; however, due to their discontinuous nature, little or no underflow occurs between basins. Recharge occurs from surrounding consolidated rock and inflow from stream infiltration. The central AMAs (Phoenix, Pinal and Tucson) contain deep alluvial aquifers and significant volumes of water in storage. However, since aquifer recharge rates are relatively low and pumping volumes are large, the aquifers have been in an overdraft condition. Within an AMA, overdraft is a condition where groundwater is pumped in excess of safe-yield. The definition of safe-yield is, “to achieve and thereafter maintain a long-term balance between the annual amount of groundwater withdrawn in an active management area and the annual amount of natural and artificial groundwater in an active management area.” A.R.S. § 45-561(12). The Prescott AMA aquifers are more discontinuous and less extensive than the large basin fill aquifers of the central 1 Except as noted. much of the information in this section is taken from the Arizona Water Resources Assessment, Volume II, 1994 and the Third Management Plans for the Active Management Areas (ADWR, 1999). 6 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 AMAs. As with the central AMAs, the Prescott AMA is in an overdraft condition. In the Santa Cruz AMA there is a close interrelationship between water levels in the stream alluvium along the Santa Cruz River, and precipitation and drought events. The Santa Cruz AMA is currently in a safe-yield condition. All of the AMAs, with the exception of the Santa Cruz AMA, contain sub-basins: two in the Prescott AMA, seven in the Phoenix AMA, five in the Pinal AMA, and two in the Tucson AMA. Characteristics of each sub-basin are described individually below. Central Basins Phoenix AMA There are seven groundwater sub-basins in the Phoenix AMA: East Salt River Valley, West Salt River Valley, Hassayampa, Rainbow Valley, Fountain Hills, Lake Pleasant, and Carefree. Each sub-basin has its own unique hydrogeologic characteristics. The primary source of groundwater in the AMA is basin fill sediments. Three distinct water bearing units are identified in most of the sub-basins: an upper alluvial unit, a middle fine-grained unit, and a lower conglomerate unit. Although conditions and circumstances vary across the AMA, most groundwater is pumped from the middle unit. Bedrock, consisting of metamorphic and igneous rock, underlies the basin fill sediments and is not considered to be an aquifer. Well yields throughout the AMA are generally high, with median well yields of over 1,400 gpm reported (Table 8.1-6). Groundwater quality is generally suitable for most uses, but 35 groundwater contamination sites associated with industrial and other activities have been identified in the AMA. Volatile Organic Compounds (VOCs) are the most common contaminant at these sites. Over 1,500 measurements have been made of parameter concentrations that have equaled or exceeded drinking water standards. Of these, nitrate, fluoride, arsenic, manganese and organics are reportedly the most common. All water providers in Arizona that serve more than 25 people or having 15 or more connections are regulated under the Safe Drinking Water Act and treat water supplies to meet drinking water standards. Detailed information on groundwater quality in the Phoenix AMA is found in the 1999 Third Management Plan, and in Volume II of the 1994 Arizona Water Resources Assessment. The East Salt River Valley Sub-basin encompasses the eastern part of the AMA and includes a portion of the City of Phoenix, the cities of Scottsdale, Tempe, Mesa, and Chandler, and the towns of Superior, Apache Junction, Gilbert and Queen Creek. Basin fill sediments extend from less than 100 feet near the basin edges to over 10,000 feet southeast of Gilbert, while the middle unit ranges in thickness from less than 100 feet to over 1,800 feet southeast of Gilbert. Groundwater flows into the sub-basin from the Lake Pleasant Sub-basin, the Eloy Sub-basin in the Pinal AMA, and between the Santan and Sacaton mountains in the southern part of the sub-basin. Groundwater also flows toward a cone of depression caused by groundwater pumping east of Chandler (see Figure 8.1-6). ADWR (1991) estimated the volume of groundwater in storage at 66 maf to a depth of 1,200 feet below land surface (bls). Natural groundwater recharge occurs along stream channels and from mountain front recharge. Substantial water level rises were measured between 1991-1992 and 2002-2003 in several wells in the sub-basin (see Figure 8.1-6A). Increases of over 60 feet were reported in some areas due to a combination of cessation of farming and associated reduction in Section 8.0 Overview DRAFT 7 Arizona Water Atlas Volume 8 pumping, and direct use and recharge of CAP water. Groundwater level depths measured during 2002-2003 ranged from ten feet bls near Superior to over 800 feet bls south of Cave Creek. The West Salt River Valley Sub-basin includes the communities of Phoenix, Buckeye, Surprise, Glendale, Peoria, Goodyear, Tolleson and Avondale. It is a broad, gently-sloping alluvial plain bounded by hills and low-elevation mountains with a depth to bedrock of over 10,000 feet beneath the Luke Air Force Base area. A large salt body lies southeast of Luke Air Force Base at a depth of 880 feet to over 6,000 feet, which locally affects groundwater salinity. The middle alluvial unit ranges in thickness from less than 100 feet to over 1,300 feet southwest of Glendale. ADWR (1991) estimated the volume of water is storage in the sub-basin was 59 maf to a depth of 1,200 feet. Natural groundwater recharge occurs along stream channels from mountain front recharge. Groundwater also enters the sub-basin from the Lake Pleasant, northern Hassayampa and East Salt River Valley sub-basins, and from the Maricopa-Stanfield Sub-basin in the Pinal AMA. Groundwater flow historically was toward and along the Salt and Gila Rivers. A cone of depression has formed in the vicinity of Sun City and Litchfield Park where water level declines of more than 300 feet in the area of Luke Air Force Base resulted in surface subsidence of more than 18 feet by 1991 (see Figure 8.1-6) (ADWR, 1996). While groundwater levels rose in that part of the sub-basin between 1991-1992 and 2002-2003, they declined in the Glendale/Goodyear/ Phoenix area. Depths to groundwater vary widely in the sub-basin with shallower levels present south of I-10 along the Salt and Gila River drainage (Figure 8.1-6D). The Hassayampa Sub-basin consists of the largely undeveloped Hassayampa Plain in the north and the lower Hassayampa area in the south. The sub-basin is bounded by hills and mountains and drained by the ephemeral Hassayampa River. There is little geologic data for the northern part of the sub-basin so the basin fill sequence is not well understood. However, depths to bedrock beneath the alluvial plain range from a few tens of feet near the basin margins to over 1,200 feet near the sub-basin center. The lower Hassayampa includes the Tonopah Desert and Centennial Wash area where the depth to bedrock is over 1,200 feet at its center. Groundwater enters the Hassayampa Plain from the northeast and groundwater flow is south toward the Gila River. Groundwater historically flowed into the sub-basin from the West Salt River Valley Sub-basin, but is intermittently interrupted due to groundwater pumping in the West Salt River Valley. Sources of groundwater recharge include streambed (Gila and Hassayampa rivers) infiltration and mountain front recharge. The sub-basin has experienced groundwater level rises in several areas while primarily modest declines have been observed near Tonopah and at other locations throughout the sub-basin. Cones of depression exist in Tonopah and south of Tonopah in the Centennial Wash area (see Figure 8.1-6). Depth to groundwater range from about 20 feet bls in the southwest to over 600 feet bls in the northern part of the sub-basin (Figure 8.1-6B). The Rainbow Valley Sub-basin is an undeveloped alluvial plain located in the southern part of the AMA and drained by Waterman Wash, an ephemeral stream that joins the Gila River near Buckeye. Depths to bedrock may be greater than 9,600 feet in the center of the sub-basin. The basin fill sequence consists of poorly sorted gravel, sand, silt and clay. Recharge includes streambed infiltration along Waterman Wash and mountain front recharge. Groundwater flow is from south to north and may have historically entered the sub-basin from the Maricopa-Stanfield Sub-basin in the Pinal AMA. Groundwater levels generally declined between 1991-1992 and 2002-2003. 8 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 Depths to groundwater measured in 2002-2003 ranged from 140 feet bls to almost 500 feet bls (Figure 8.1-6C). The Fountain Hills Sub-basin is an extensively dissected alluvial plain bounded by mountains. It is drained by the lower Verde River, which is perennial along the axis of the sub-basin, and by the Salt River in the southern part of the sub-basin. The two rivers converge in the southern portion of the sub-basin. The regional aquifer consists of an older basin fill sequence and unconsolidated alluvium deposited by and hydraulically connected to the Verde River. The depth to bedrock may exceed 4,800 feet. The general groundwater flow direction is from north to south, parallel to the sub-basin axis. The regional aquifer may not be connected to adjacent sub-basins. Groundwater recharge occurs through streambed (Verde and Salt rivers) infiltration and from mountain front recharge. Groundwater levels rose in a number of wells in the sub-basin between 1991-1992 and 2002-2003 while depth to groundwater ranged from 51 feet bls to over 500 feet bls (see Figure 8.1-6A). The Lake Pleasant Sub-basin is a relatively small, gently sloping alluvial plain surrounded by hills and mountains in the northern part of the AMA. It is drained by the lower Agua Fria River, by New River and by Skunk Creek. Depths to bedrock exceed 800 feet near the center of the subbasin and the basin fill locally may include interbedded basalt. Reported well yields are generally between 100 and 500 gpm. In the New River area, the local aquifer consists of fractured schist and gneiss and the groundwater supply is drought-sensitive. Well yields in this area are relatively low. Groundwater recharge includes streambed infiltration and mountain front recharge. Groundwater flow is generally from north to south and into the West Salt River Valley and East Salt River Valley sub-basins. Groundwater levels were stable or rose in most measured wells between 1991-1992 and 2002-2003. Depths to water ranged from 17 feet bls to almost 300 feet bls in 2002-2003. (see Figure 8.1-6D) The Carefree Sub-basin, located in the northeastern part of the AMA, contains a small northwesttrending alluvial plain in the southern part of the sub-basin that is groundwater-bearing. The sub-basin is drained by Cave Creek, a small ephemeral stream. The basin fill in the Carefree Sub-basin is relatively thin (up to 2,000 feet thick) and composed of older, partially-consolidated to consolidated sedimentary rocks. The primary aquifer is the Carefree Formation consisting of alluvial fan and playa deposits and underlain by volcanic rocks. The Grapevine Member is the only significant source of groundwater in this formation and reaches a maximum thickness of 1,300 feet (ADWR, 1991). ADWR (1994) estimated that the volume of groundwater in storage in the Carefree Sub-basin was 570,000 acre-feet to a depth of 1,200 feet bls. Natural groundwater recharge is from mountain front recharge and infiltration of streamflow along Cave Creek. Groundwater flow is generally to the west-southwest. Groundwater levels began declining in the early 1960s, but rose in several wells between 1991-1992 to 2002-2003 as many local golf courses converted from solely groundwater to a combination of CAP water, groundwater and effluent. Depth to water in wells measured in 2002-2003 ranged from 27 feet bls to 330 feet bls. Well yields vary with yields east of Carefree in excess of 1,000 gpm (Figure 8.1-8). Pinal AMA The Pinal AMA consists of five sub-basins with unique groundwater underflow, storage, and surface water characteristics. These sub-basins include the Maricopa-Stanfield, Eloy, Vekol Valley, Santa Section 8.0 Overview DRAFT 9 Arizona Water Atlas Volume 8 Rosa Valley, and Aguirre Valley. Sub-basin boundaries follow surface water topographic divides, and in the case of the Eloy and Maricopa-Stanfield sub-basins, a groundwater divide. Groundwater underflow between these two sub-basins is limited or non-existent. Most groundwater development has occurred within the Maricopa-Stanfield and Eloy sub-basins while relatively little development and hydrologic information is available for the Vekol Valley, Santa Rosa Valley and Aguirre Valley sub-basins. The best groundwater-bearing materials in the Maricopa-Stanfield and Eloy sub-basins consist of the unconsolidated sands, gravels, silts, and clays that were deposited by the ancestral Gila and Santa Cruz rivers. Natural recharge is primarily from streambed infiltration along the Gila and Santa Cruz rivers, which produce relatively large volumes of runoff from upstream basins outside the AMA following heavy rains. Lesser amounts of natural recharge occur from mountain fronts. The estimated groundwater in storage in the two sub-basins is about 31.2 maf with another 4 maf of storage in the Vekol Valley Sub-basin. Median well yield is approximately 1,000 gpm. (see Table 8.2-6) Demand for water by irrigated agriculture has drained a large portion of the Upper Alluvial Unit in both sub-basins and changed the direction of groundwater flow between sub-basins. In the Maricopa-Stanfield Sub-basin, groundwater flow is north toward the Gila River and toward cones of depression that have formed west of both Maricopa and Stanfield (see Figure 8.2-6). However, groundwater levels are now recovering and rising in much of the sub-basin due to use of CAP water in lieu of groundwater pumping. Water level rises of more than 60 feet were observed in many wells between 1993-1994 and 2003-2004 (Figure 8.2-6). Depths to groundwater range from 51 feet bls near the Gila River in the north to more than 600 feet bls in the vicinity of Stanfield (Figure 8.2-6A). In the Eloy Sub-basin, groundwater flow is generally to the north toward the Gila River and Phoenix AMA. Reductions in groundwater pumping and use of CAP water have contributed to rising water levels in several wells in this sub-basin. However, groundwater levels are also declining in the north due to dissipation of a groundwater mound formed after Gila River flooding; and in the south central sub-basin, probably from deep well pumping (see Figure 8.2-6). Depth to groundwater ranges from 53 feet bls in the northeast to over 400 feet bls near Picacho (Figure 8.2-6B). Water quality in the Pinal AMA generally meets state and federal drinking water standards, however exceedences of nitrate, fluoride, arsenic and to a lesser extent, other constituents have been measured at some locations (see Table 8.2-8). Pesticide, jet-fuel and hydraulic fluid contamination is found at several contamination sites in the AMA (Table 8.2-9 and Figure 8.2-11). Santa Cruz AMA Basin fill sediments along the Santa Cruz River east and north of the City of Nogales to Amado form three aquifer units. Listed in ascending order, they are the Nogales Formation, the Older Alluvium, and the Younger Alluvium (also referred to as the stream alluvium). Both alluvial units are generally unconfined, hydraulically connected, and yield water to wells, although the Older Alluvium aquifer exhibits semi-confined and confined conditions in some places, most notably in Potrero Creek. The Nogales Formation is not generally considered an important aquifer, although local exceptions may occur. The Older Alluvium varies in thickness from a few feet along the 10 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 mountains to more than 1,000 feet in the north-central part of the basin. It exhibits relatively low transmissivity and well yields are often low in wells drilled in this aquifer. The Younger Alluvium forms the most productive and most widely utilized aquifer in the AMA with well yields in excess of 1,000 gpm common. The Younger Alluvium ranges from about 40 to 150 feet thick, becoming thicker and wider to the north along the Santa Cruz River. Groundwater storage in the Younger Alluvium has been estimated at about 160,000 acre-feet. Water levels have generally declined in wells measured in 1995 and 2004-2005 throughout the AMA, with most declines totaling from 1 to 15 feet (see Figure 8.4-6). However, a characteristic of the Younger Alluvium in the Santa Cruz AMA is the potential for rapid water level fluctuations. Natural groundwater recharge occurs from infiltration of Santa Cruz River channel flow and mountain front recharge. Groundwater inflow enters the basin along the Santa Cruz River and west of Nogales. Groundwater flow is then generally south to north. Groundwater quality is generally good, although arsenic concentrations exceeding the safe drinking water standard have been measured at some wells in the basin. In addition, there are two sites near Nogales with VOC and chromium contamination (see Table 8.4-7 and Figure 8.4-9). Tucson AMA The Tucson AMA contains two parallel sub-basins. The Upper Santa Cruz Valley Sub-basin is located in the eastern half of the AMA and the Avra Valley Sub-basin is located in the western half. The sub-basins consist of deep alluvial basins filled with layers of sediments and surrounded by mountains. These sediments contain substantial volumes of groundwater, but the composition and productivity of the sediment layers differ between the two sub-basins. In the center of the Upper Santa Cruz Valley Sub-basin, the depth to bedrock is in excess of 11,000 feet. Alluvial sediments in this sub-basin have been divided into four hydrogeologic units that form the main regional aquifer and are hydrologically connected to varying degrees. In descending order these units are the recent alluvial deposits, Fort Lowell Formation, Tinaja Beds and Pantano Formation. A basement unit underlies the sediments, forming a relatively impermeable bedrock floor that extends to the surrounding mountains. The recent alluvial deposits occupy streambed channels of the Santa Cruz River and its major tributaries and are generally less than 100 feet thick. The Fort Lowell Formation consists of unconsolidated to moderately consolidated sands and silts that are 300 to 400 feet thick throughout the sub-basin. The underlying Tinaja Beds are up to 5,000 feet thick in the center of the sub-basin and consist of sandstones, conglomerates, siltstones and mudstones. The Tinaja Beds have become the principal supply of groundwater in the Tucson AMA due to widespread dewatering of the overlying Fort Lowell Formation. Beneath the Tinaja Beds, the Pantano Formation, composed of consolidated sandstones, conglomerates and mudstones, is little used as a water supply because of its depth and relative low well yields. Groundwater flow is from the mountains toward the center of the basin and then north-northwest and north from the Santa Cruz AMA. The Avra Valley Sub-basin is composed of upper and lower alluvial units. The upper unit is the primary water producing unit in the sub-basin. Composed of silt and gravel, it includes the streambed deposits along Altar and Brawley washes and ranges in thickness from less than 100 feet to more than 1,000 feet. The lower alluvial unit consists of gravel and conglomerates at the edges of the Section 8.0 Overview DRAFT 11 Arizona Water Atlas Volume 8 valley, grading to silts and mudstones along the central axis of the sub-basin. Groundwater flow is from the south to north. Natural recharge is from mountain front and stream channel (Santa Cruz River) recharge and from groundwater inflow from the Santa Cruz AMA. About 84% of the total net natural recharge in the basin occurs within the Upper Santa Cruz Valley Sub-basin. Estimates of groundwater in storage for the Tucson AMA during predevelopment times ranges from 68 maf to 76 maf (ADWR, 2006a). As shown in Figure 8.5-8, well yields in excess of 1,000 gpm are found in the vicinity of Sahuarita and Green Valley, near Marana and north of Three Points. Water level rises have been recorded in the last ten years in the northern half of the Avra Valley Sub-basin due to agricultural retirement, use of CAP water in lieu of groundwater pumping and groundwater recharge activities (see Figure 8.5-6A). Similar widespread water level rises have not been noted in the Upper Santa Cruz Subbasin with the exception of an area north of Sahuarita where CAP water is being recharged at the Pima Mine Road Underground Storage Facility. Elsewhere in the sub-basin, water levels have generally decreased (see Figure 8.5-6B). Water quality in the Tucson AMA is suitable for most uses, although 47 federally recognized groundwater contamination sites have been identified; elevated concentrations of certain natural constituents, including arsenic, fluoride and metals, are measured in wells. Also, nitrate, sulfate and total dissolved solid concentrations that exceed standards have been detected in wells near mining and agricultural operations. Volatile organic compounds (VOCs) associated with industrial and transportation activities are common at the contamination sites (See Table 8.5-9). Highlands Basins Prescott AMA The Prescott AMA consists of two sub-basins, the Little Chino in the north and the Upper Agua Fria in the south. The sub-basins are separated by a surface drainage divide. Prescott AMA aquifers are discontinuous, with the major aquifer found in a deep structural trough that extends 25 miles from near Dewey-Humboldt to near Del Rio Springs. The trough appears to have formed from basin-and-range faulting and warping and was gradually filled with alluvial, sedimentary, and volcanic rocks of Quarternary to upper Tertiary age. Three hydrogeologic units have been identified in the AMA. In ascending order they are the Basement Unit, the Lower Volcanic Unit, and the Upper Alluvial Unit. The relatively impermeable Basement Unit is composed of igneous and metamorphic rocks that form the floor and sides of the groundwater sub-basins and is exposed at land surface in the surrounding mountains. The Basement Unit has limited groundwater storage and production capacity and is not regarded as an aquifer except for domestic purposes. ADWR (2005) estimated that there was 2.9 maf of groundwater in storage in the AMA. The Lower Volcanic Unit overlies the Basement Unit in most of the Little Chino Sub-basin. It is composed of a thick sequence of basaltic and andesitic lava flows interbedded with layers of pyroclastic and alluvial material. The productive thickness of this unit is estimated to range 12 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 from less than 100 feet up to several hundred feet. The Lower Volcanic Unit forms a highly productive confined (artesian) aquifer with discharge points northwest of and at Del Rio Springs. Natural recharge to the Lower Volcanic Unit aquifer occurs mainly through infiltration of runoff in ephemeral stream channels and along the mountain fronts of the Little Chino Sub-basin. The Upper Alluvial Unit occurs as relatively thick sedimentary and volcanic rocks that fill a deep structural trough that extends across both sub-basins. This unit constitutes the main, unconfined aquifer in the Prescott AMA. Natural recharge to this unit is from streambed infiltration and mountain front recharge. The thickness of the unit varies considerably. In the Upper Agua Fria Subbasin it varies from 800-1,200 feet near Prescott Valley to 200-400 feet near Dewey-Humboldt. In the Little Chino Sub-basin, the thickness of the basin fill is difficult to determine but is estimated to be about 700 feet thick near Del Rio Springs with a median thickness of about 450 feet (Blasch et al., 2006). The combined thickness of the Upper Alluvial Unit and Lower Volcanic Unit is greatest in the central and southeastern portions of the sub-basin. Groundwater flows generally from the mountain fronts toward the valleys, then north from the Little Chino Sub-basin and south from the Upper Agua Fria Sub-basin. Between 1993-1994 and 2004, water levels declined in most measured wells (Figure 8.3-6). Depths to groundwater in wells ranged from 16 feet bls near Del Rio Springs to almost 500 feet bls in the east-central part of the basin. Well yields are generally between 500 gpm and 1,000 gpm in measured wells in the vicinity of Chino Valley, and between 100 gpm to 500 gpm in the Upper Agua Fria Sub-basin. The median reported well yield among 78 wells with a diameter greater than 10 inches was 763 gpm (Table 8.3-6). Water quality is generally good; however arsenic, and to a lesser extent other constituents at concentrations exceeding the safe drinking water standards, are found at a number of locations (Table 8.3-8). Sites contaminated with hydrocarbons, lead, cyanide and other contaminants are found near Prescott, Chino Valley and Dewey-Humboldt (see Figure 8.3-11). Surface Water Hydrology The U.S. Geological Survey (USGS) divides the United States into successively smaller hydrologic units based on hydrologic features. These units are classified into four descending levels. From largest to smallest they are: regions, subregions, accounting units and cataloging units. Each hydrologic unit is identified by a hydrologic unit code (HUC) consisting of two to eight digits depending on the unit level. A 6-digit code corresponds to accounting units, which are used by the USGS for designing and managing the National Water Data Network. The AMA planning area encompasses portions of six watersheds at the accounting unit level: the Verde River, the Agua Fria River-Lower Gila River, the Salt River, the Middle Gila River, the Santa Cruz River and the Rio Asuncion (Figure 8.0-4). More detailed information on stream flow gages, springs, reservoirs and general surface water characteristics are found in the individual AMA sections. Section 8.0 Overview DRAFT 13 Arizona Water Atlas Volume 8 14 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 Verde River The 6,100 square mile Verde River Watershed is located in north-central Arizona. A large part of the watershed is located in the Verde River groundwater basin (See Volume 5, Figure 5.0-3). The northern portion of the watershed begins near Seligman with tributaries of Big Chino Wash. The Verde River is perennial and travels almost 140 miles starting from Sullivan Lake Dam just north of the Prescott AMA, eastward to Perkinsville, southeastward to Fossil Creek, then southward through two reservoirs, (Horseshoe and Bartlett), to its confluence with the Salt River. The last 25 miles of the Verde River, and the southernmost part of the watershed are located in the Phoenix AMA. The Verde River enters the AMA in the north Fountain Hills Sub-basin and moves southward where it joins the Salt River between Stewart Mountain Dam and Granite Reef Diversion Dam. The Verde River is regulated by Horseshoe Dam and Bartlett Dam outside the Phoenix AMA, both of which are part of the Salt River Project (SRP). The SRP is composed of two entities that provide water and power to the Phoenix metropolitan area. One of the entities, the Salt River Valley Water Users Association is a private corporation that delivers nearly one maf of water annually to the Phoenix area through an extensive water delivery system that includes reservoirs, wells, canals and irrigation laterals. The northwestern portion of the Prescott AMA, the Little Chino Sub-basin, is also located in the Verde River watershed. Granite Creek and Willow Creek comprise the major tributaries that drain the Little Chino Sub-basin into the Verde River. An estimated 14% of the base flow in the Verde River comes from the Little Chino Sub-basin (Wirt, 2005). Dams were constructed on both Granite Creek and Willow Creek, forming Watson Lake and Willow Lake respectively, to store water for diversion to the Chino Valley Irrigation District (CVID). The lakes are now used by the City of Prescott for recreation and municipal water use. During periods of prolonged flooding, flows from these lakes join at the confluence of Granite and Willow Creeks, and then flow northward to join the Verde River near Paulden outside the AMA (see Figure 8.3-4). Little Chino Creek and Big Draw Creek drain the northwestern part of the Little Chino Sub-basin. Little Chino Creek drains the CVID area and flows into the Del Rio Springs area where groundwater naturally discharges at the surface. Del Rio Springs, located in the northern part of the Prescott AMA, is the only large spring in the AMA with a discharge of 874 gpm measured in 1999. In this area, spring discharge provides essentially permanent baseflow conditions below the springs. The only other major spring in this part of the watershed is Camp Spring northeast of Carefree in the Phoenix AMA with a discharge of about 75 gpm. Sycamore Creek, a tributary of the Verde River, and Camp Creek northeast of Carefree both have perennial flow. Streamgages are located at Del Rio Springs, along Willow and Watson Creeks, and on the Verde River in the Phoenix AMA. Mean flows at the three Granite Creek streamgages are between approximately 3,500 and 5,000 acre-feet a year. Flows on the Verde River in the Phoenix AMA are regulated by releases from Bartlett and Horseshoe Dams. The highest reported annual flow at the two Verde River gages was approximately 1.8 maf in 1993, while the median flow is approximately 298,000 acre-feet (Table 8.1-2). Agua Fria – Lower Gila River The Agua Fria – Lower Gila River Watershed begins near Prescott and extends south past Gila Section 8.0 Overview DRAFT 15 Arizona Water Atlas Volume 8 Bend in the Lower Colorado River Planning Area. It includes drainage from the Agua Fria River, the Lower Hassayampa River and the Gila River. Within the AMA planning area, this watershed encompasses the southeastern portion of the Prescott AMA as well as the western half of the Phoenix AMA. In the Prescott AMA, the Agua Fria – Lower Gila River Watershed includes the Upper Agua Fria Sub-basin. Upper Lynx Creek, Lynx Creek and the Agua Fria River drain the sub-basin. Most of the runoff from Lynx Creek is impounded by a dam and is reserved for recreational and industrial use. A short stretch of the Agua Fria River becomes perennial before leaving the AMA and a portion of it receives effluent discharged from the Prescott Valley Wastewater Treatment Facility (Figure 8.3-10). All other flows in the Upper Agua Fria Sub-basin are ephemeral. All or portions of five Phoenix AMA sub-basins lie within the Agua Fria – Lower Gila River Watershed including Carefree, Lake Pleasant, Hassayampa, West Salt River Valley and Rainbow Valley. The Agua Fria River enters the AMA approximately 20 miles north of Peoria, in the Lake Pleasant Sub-basin. It is impounded by New Waddell Dam at the northern boundary of the subbasin and only flows below the dam when water is released during major flood events. From there it flows south along the western edge of the Phoenix metropolitan area and joins the Gila River south of Avondale. Downstream of the confluence of the Salt River, the Gila River flows year round due to effluent discharge from the City of Phoenix 23rd and 91st Avenue wastewater treatment plants (WWTP) into the Salt River, and also from return flows from nearby agricultural areas. The Gila River has been designated as impaired by the Arizona Department of Environmental Quality (ADEQ) due to pesticide concentrations that exceed the use standard (Figure 8.1-10A and Table 8.1-8B). The water is diverted along the way for agricultural and industrial uses. The Gila River exits the Phoenix AMA at Gillespie Dam. The Hassayampa River originates in the Bradshaw Mountains and flows into the Hassayampa Subbasin to its confluence with the Gila River west of Buckeye. It is an ephemeral watercourse in the AMA with the exception of short perennial reaches where it enters the AMA and near the Gila River confluence. The Hassayampa River is impaired above the confluence due to high concentrations of selenium and boron (Table 8.1-8B and Figure 8.1-10A). The only major spring in the watershed is Seven Springs north of Carefree with a discharge of about 75 gpm. Cave Creek and Seven Springs Wash located northeast of Carefree have perennial reaches (Figure 8.1-5). Flow records from streamgages on watercourses in the watershed are shown in Tables 8.1-2 and 8.3-2. Annual median flow at the Agua Fria River near the Humboldt gage is about 3,400 acre-feet. Annual median flow on the Hassayampa River near Morristown is about 6,500 acre-feet a year. The highest flow measured in the watershed was at a gage on the Gila River (#9514100) with a flow of 6.1 maf in 1993, although the median flow at this gage is only about 12,000 acre-feet a year. (Table 8.1-2) Salt River Most of the Salt River Watershed is within the Salt River and Tonto Creek basins in the Central 16 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 Highlands Planning Area. Its western edge extends into the Phoenix AMA to the confluence of the Salt and Gila rivers. The Salt River originates in eastern Arizona and drains approximately 6,000 square miles of the Mogollon Rim area in the east-central part of the State. Before entering the Phoenix AMA in the Fountain Hills Sub-basin, surface water from the Salt River Watershed passes through a series of four reservoirs: Roosevelt Lake, Apache Lake, Canyon Lake and Saguaro Lake. These reservoirs and associated dams, operated by the SRP are used to supply water to the agricultural, municipal and industrial sectors in the Phoenix AMA. The Salt River channel enters the AMA north of the Goldfield Mountains; crosses toward the southwest through the East Salt River Valley and West Salt River Valley sub-basins and the cities of Mesa, Tempe, Scottsdale and Phoenix; and joins the Gila River near Laveen. Downstream from the Granite Reef Diversion Dam, the Salt River is ephemeral, only flowing in response to flooding or reservoir releases. The Salt River is perennial further downstream due to effluent discharges from the 23rd Avenue and 91st Avenue WWTPs. There are no major springs in the AMA portion of the watershed. Flow records from streamgages in the watershed are found in Table 8.1-2. Annual median flow on the Salt River below Stewart Mountain Dam is about 585,700 acre feet with a maximum flow of over 3.2 maf in 1993. Further downstream near its confluence with the Gila River and below the Granite Reef Diversion Dam, annual median flow on the Salt River at 51st Avenue is about 4,300 acre-feet a year. Middle Gila River The Middle Gila River Watershed extends west from Coolidge Dam on the Gila River, located in the Southeastern Arizona Planning Area, to the confluence of the Gila and Salt Rivers. The San Pedro and San Francisco rivers are major tributaries to the Gila River outside of the AMA Planning Area. Portions of the Phoenix AMA, Pinal AMA and Tucson AMA are located in this watershed. The Gila River enters the Pinal AMA in its northeastern corner and traverses from east to west. In predevelopment times, the Gila flowed year round through this area. Pre-development flows on the portion of the Gila River that passes through the Pinal AMA are estimated to have been about 500,000 acre-feet per year. The first records of San Carlos Irrigation Project (SCIP) diversions begin in 1930, although diversions to non-Indian farmers began much earlier. Annual diversions from the Gila River by SCIP at Ashurst-Hayden Diversion Dam northeast of Florence in the Pinal AMA have averaged 245,000 acre-feet per year from 1930 to 1995. There are no major springs in this portion of the Middle Gila River watershed. Short reaches of Queen Creek and Arnett Creek near Superior are perennial. Queen Creek has been designated as impaired from its headwaters about nine miles downstream due to elevated copper concentrations from mining discharge (Table 8.1-8B and Figure 8.1-10A). Flow records from streamgages in the watershed are found in Tables 8.1-2 and 8.2-2. Annual median flow measured at the streamgage, “Queen Creek below Whitlow Dam near Superior”, is about 1,600 acre-feet. Gages on the Gila River are either discontinued or have only recent data. The Gila River near Laveen gage has the longest period of record, 55 years, but was discontinued in 1994. The annual median flow at that gage was 9,420 acre-feet with a maximum flow of almost 1.2 maf in 1993. Santa Cruz River A large portion of the AMA Planning Area falls within the Santa Cruz River Watershed, including the Santa Cruz AMA and most of the Tucson and Pinal AMAs. The Santa Cruz River is the main Section 8.0 Overview DRAFT 17 Arizona Water Atlas Volume 8 surface water drainage in the Santa Cruz and Tucson AMAs. The river originates in the San Rafael Valley east of the planning area and flows southward to Mexico before turning north and reentering the U.S. east of Nogales. Within the planning area it extends from the international border northwestward to its confluence with the Gila River (where it is known as the Santa Cruz Wash) in the northern portion of the Pinal AMA. Major tributaries to the river in the Santa Cruz AMA are Nogales Wash, Sopori Wash and Sonoita Creek. Tributaries to the Santa Cruz River in the Tucson AMA include Rillito Creek, Cañada del Oro Wash and Brawley Wash. Three smaller streams (Vekol Wash, Santa Rosa Wash and Aguirre Wash) drain the southwestern portion of the Pinal AMA. These washes join Santa Cruz Wash upstream from its confluence with the Gila River. Prior to development, the Santa Cruz River was mostly perennial in its southernmost reach from its headwaters in the San Rafael Valley to near Tubac, often as a series of Cienegas (marshes). North of Tubac, a few short perennial reaches existed including reaches near the mission of San Xavier del Bac south of Tucson and at “A” Mountain near downtown Tucson. From the Nine-Mile water hole north of the confluence of the Santa Cruz River and the Rillito River in Tucson, to its confluence with the Gila River, the Santa Cruz River was dry except during floods. (Tellman, et al., 1997) Currently, within the Tucson AMA and the Santa Cruz AMA, two segments of the Santa Cruz River flow year round due to wastewater discharges. In 2006, approximately 54,000 acre-feet was discharged at the Ina and Roger Road WWTPs by Pima County. In 2004, approximately 16,200 acre-feet of sewage was treated at the Nogales International WWTP, which treats sewage from both Nogales, Sonora and Nogales, Arizona prior to discharge to the river. Approximately 11,500 acre-feet of the influent was from Mexico. In the Pinal AMA, a portion of the Santa Cruz River receives wastewater discharge from the Casa Grande WWTP. Other perennial flows include portions of Sabino, Romero, Cienega and Rincon Creeks in the east central part of the Tucson AMA and Sonoita Creek in the Santa Cruz AMA. Nogales Wash, a tributary of the Santa Cruz River, originates about five miles south of the international border in Sonora and enters Arizona as a covered floodway. It joins the Santa Cruz River about 8 miles north of the border. Nogales Wash is the major drainage system for both Nogales, Arizona and Nogales, Sonora. (Varady, et al., 1995) Springs create perennial flow in Nogales Wash near its headwaters in Mexico and below the springs, storm flows and uncontrolled sewage discharges also contribute to its flow (IBWC, 1998). In the Santa Cruz AMA the Santa Cruz River and Nogales Wash have designated impaired reaches due to elevated levels of E. coli and other constituents (Figure 8.4-9 and Table 8.4-7). There are ten major springs in the watershed located near Arivaca, in mountains east of Tucson, and west of Amado in the Santa Cruz AMA. The spring with the largest discharge is Sopori, located west of Amado, with a discharge rate of 377 gpm measured in 1952 (see Tables 8.4-5 and 8.5-5). Flow records from streamgages in the watershed are found in Tables 8.4-2 and 8.5-2. The annual median flow at the Santa Cruz River near Nogales is 14,013 acre feet with a maximum flow of over 88,000 acre-feet in 1983. Downstream, median flow at the gage on the Santa Cruz River at Cortaro is 38,655 acre-feet with a maximum flow in 1993 of over 182,000 acre-feet. 18 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 Rio Asuncion A small part of the Rio Asuncion Watershed is located at the base of the Tucson AMA along the international border. This watershed drains a large area of northwest Sonora, Mexico and discharges into the Sea of Cortez. Sycamore Creek, a perennial stream located in this watershed, flows southsouthwest into Mexico. Due to its rich biological diversity, a portion of Sycamore Canyon has been designated as the Gooding Research Natural Area. 8.0.3 Climate Climate in the AMA Planning Area varies widely due to its geographic extent, with significant temperature and rainfall differences between some AMAs. Average annual temperatures range from 72.9°F in the Phoenix AMA to 53.3°F in the Prescott AMA compared to the statewide average of 59.5°F. Phoenix and Tucson are the warmest AMAs except during the summer monsoon season when Tucson receives a significant amount of its annual rainfall and associated cooler temperatures (Figure 8.0-5). Average annual precipitation (1971-2000) ranges from 8.3 inches at Phoenix Sky Harbor Airport to 18.7 inches at Nogales and Prescott. Figure 8.0-5 Average monthly temperature from 1952-2007 in the AMA Planning Area Source: WRCC, 2008 Section 8.0 Overview DRAFT 19 Arizona Water Atlas Volume 8 The AMA Planning Area exhibits a bi-modal precipitation seasonality that is characteristic of Arizona (Figure 8.0-6). During the winter and spring, frontal storm systems move west-to-east, guided by the jet stream. Summer monsoon thunderstorms also deliver significant amounts of precipitation, particularly in the Santa Cruz AMA. While precipitation amounts vary widely across the planning area, there are also strong year-to-year variations, due primarily to the influence of the El Nino-Southern Oscillation, as well as long-term wet and dry periods that are linked to multidecadal ocean variations. Many of the wettest and driest periods since 1960 were synchronous throughout the AMAs with notable wet periods in the late 1970s, early 1980s and early 1990s. Notable dry periods were the early 1960s, the early 1970s and the period from 1996 through 2006 (Figure 8.0-7). The greatest year-to-year precipitation variations during this period occurred in the Phoenix AMA and the least variation in the Prescott AMA, with the exception of 1965 when Prescott received almost double its annual rainfall. Figure 8.0-6 Average monthly precipitation from 1948-1952 to 2006-2007 Note: Data are from Phoenix, Sky Harbor Airport; Casa Grande NM; Prescott Sta.; Nogales 6N; and Univ. of Arizona WRCC Stations.

Each time series was constructed from one recording station. Figure author: Zack Guido, CLIMAS The planning area encompasses parts of five of Arizona’s seven climate divisions. A climate division is a region within a state that is generally climatically homogenous. Long-term climate data for Arizona’s climate divisions have been reconstructed from tree ring and instrumental data. These data show that since 1000 A.D., Climate Division 7 experienced more years than the other planning area climate divisions in which precipitation was less than that measured in 2002, one of the driest years in the instrumental record (CLIMAS, 2008). Climate Division 7 encompasses most of the Tucson AMA and all of the Santa Cruz AMA. Average annual temperatures in the AMA Planning Area have been increasing since 1960, a phenomenon observed throughout the state. Figure 8.0-8 shows that all of the major urban locations in the AMAs have seen temperature increases, reflecting both a regional temperature trend and the influence of urban expansion and development. The effect of urban areas on temperature, precipitation and other climate phenomena is an important consideration in the planning area. Phoenix, for example, has experienced the greatest increase in temperatures during the time period shown. Figure 8.0-9 illustrates an increase in daily minimum temperatures during the summer months in Phoenix and Tucson, and is contrasted with the modest increases measured at Casa Grande National Monument, a relatively non-urbanized area between the two cities. Research on urbanization and warming in the Phoenix metropolitan area shows that, from 1948-2000, urbanization has increased the nighttime minimum temperature in central Phoenix Section 8.0 Overview DRAFT 21 Arizona Water Atlas Volume 8 Figure 8.0-8 Average annual temperature measured between 1960 and 2007 80 Phoenix, Sky Harbor Airport Tucson, Univ. of Arizona Pinal, Casa Grande NM Santa Cruz, Nogales 6N Temperature (Fahrenheit) 75 Prescott, Prescott Sta. 70 65 60 55 2006 2004 2002 2000 1998 1996 1994 1992 1990 1988 1986 1984 1982 1980 1978 1976 1974 1972 1970 1968 1966 1964 1962 1960 50 Year Each time series was constructed from one recording station. Figure author: Zack Guido, CLIMAS (Sky Harbor Airport) by approximately 9° F and the average daily temperature by approximately 5.5° F (Baker et al., 2002). The number of days with temperatures between 59-100°F at Sky Harbor Airport has increased by about 30 days since 1948, most notably during the spring and fall. During the period 1990-2004, the Phoenix urban heat island expanded substantially, commensurate with increasing population and urban development. Recent research shows that temperatures in areas characterized by urban infill development, and areas in the core of the city were approximately 2° F and approximately 4° F warmer, respectively, than temperatures outside of urban areas (Brazel et al., 2007). Similarly, in central Phoenix the hours per day that exceed 100° F during the months of May through September have doubled since 1948 (Baker et al., 2002). Tucson’s urban heat island effect increased by approximately 5.5° F during the 20th century, with most of the warming since the late 1960s (Comrie, 2000). In the Tucson area, urban temperatures increased at almost 3 times the rate of rural temperatures. Temperature changes are not, however, uniform. Within the urban zone, variations in temperatures are caused by differences in housing density, the amount of green space, topography, and localized cold air flows downslope from mountains. The impacts of urban warming are varied and include increases in energy consumption, predominantly from longer usage of air conditioning, and stress to animals and humans. Since 1948, the total number of cooling degree days (CDD) in Phoenix has increased by 569 while the 22 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 Figure 8.0-9 Average June, July and August temperature measured between 1960 and 2007 85 Temperature (Fahrenheit) 80 75 70 65 Phoenix, Sky Harbor Airport Tucson, Univ. of Arizona Casa Grande Nat.

Each time series was constructed from one recording station. Figure author: Zack Guido, CLIMAS heating degree days (HDD) has declined by 331 (Baker et al., 2002). The CDD and HDD are indices that reflect the demand for energy needed to cool or heat a structure, respectively. Research conducted in 2003 in Phoenix found that distinct neighborhoods experience up to 7° F difference in temperature. Two recent studies suggest that urbanization and large irrigated areas in the Phoenix metro area increase precipitation to the northeast of the city (Diem and Brown, 2003; Sheperd, 2006). Average precipitation in the northeastern suburbs and exurbs of metropolitan Phoenix has increased by 12-14%, in contrast to the first half of the 20th century (Sheperd, 2006). The study suggests that urban heating, from built surfaces and buildings, affects upward motion in the atmosphere and can increase storminess beyond the urban area. Irrigation increases local water vapor in the atmosphere, and probably contributes to the increased precipitation (Diem and Brown, 2003). 8.0.4 Environmental Conditions Vegetation Information on ecoregions and biotic (vegetative) communities in the AMA Planning Area is shown on Figure 8.0-10. The planning area contains five of the six ecoregions found in Arizona; most of the planning area is within the Sonoran Desert ecoregion. The Tucson and Santa Cruz AMAs, Section 8.0 Overview DRAFT 23 Arizona Water Atlas Volume 8 in the southern portion of the planning area, contain Chihuahuan Desert with areas known as “sky islands” of Sierra Madre Occidental pine-oak forest. The northeastern portion of the Phoenix AMA and most of the Prescott AMA are in the Arizona Mountains forests region, and the northern portion of the Prescott AMA includes a portion of the Colorado Plateau shrublands region. Biotic communities range from Lower Colorado River Valley Sonoran desertscrub to Rocky Mountain (Petran) and Madrean montane conifer forest. Most of the planning area is covered by Lower Colorado River Valley and Arizona Uplands Sonoran desertscrub biotic communities. Rocky Mountain and Madrean montane conifer forests occur at the highest elevations of the Tucson AMA in the Santa Catalina and Rincon Mountains and in the Prescott AMA in the Bradshaw Mountains. These forests commonly occur between about 7,200 to 8,700 feet. Above 8,000 feet, in areas that receive from 25 to 30 inches of annual rainfall, the forest contains a mix of conifers that may include Douglas and White fir, Limber Pine, Blue Spruce, and White Pine, with Ponderosa Pine on warmer slopes. Aspen and Gambel Oak are prominent in these forests following disturbances. Below 8,000 feet, in areas that receive about 18 to 26 inches of annual precipitation, the mix of species gives way to almost pure stands of Ponderosa Pine. About half of the precipitation occurs during the growing season, which permits forests to exist on less than 25 inches of annual rainfall, making them some of the driest forests in North America (Brown, 1982). Bark beetle infestations have killed large areas of Ponderosa Pine in the Prescott AMA within and in the vicinity of the City of Prescott. Higher elevations in the Prescott AMA contain areas of Great Plains grassland and Great Basin conifer woodland not found in the other four AMAs. Great Basin Conifer (piñon-juniper) woodlands are found at elevations between about 5,000 and 7,500 feet that receive about 10 to 20 inches of annual precipitation. One of the most extensive vegetation types in the southwest, it is characterized by juniper and piñon pine trees. Great Plain grasslands, primarily composed of mixed or short-grass communities, are located in the center of the AMA at elevations above about 4,000 feet that receive between 11 and 18 inches of annual precipitation. (Brown, 1982). Madrean evergreen woodlands are relatively widespread in the Tucson and Santa Cruz AMAs. This community occurs in the Santa Catalina, Baboquivari and Santa Rita Mountains and in the mountain ranges along the U.S.-Mexico border where the mean annual precipitation exceeds 16 inches. The woodland consists of evergreen oaks, Alligator Bark and One-seed Junipers, and Mexican Pinyon Pine, and transitions to semidesert grassland at lower elevations. Cacti of the semidesert grassland may extend into the woodland. (Brown, 1982) Semi-desert grasslands occur predominantly in the Santa Cruz and Tucson AMAs with smaller areas in the Pinal AMA. These grasslands occur at elevations between 3,500 and 5,000 feet that receive annual precipitation of 10 to 17 inches. Grasses were originally perennial bunch grasses with intervening areas of bare ground. Where heavily grazed, grasses have shifted to annual species where summer rainfall is low, or to low growing sod grasses where rainfall is moderate to heavy. Shrubs, cacti and herbaceous plants are commonly found in the semi-desert grassland community. (Brown, 1982) 24 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 Section 8.0 Overview DRAFT 25 Arizona Water Atlas Volume 8 Interior chaparral occupies mid-elevation foothill and mountain slopes in the Santa Rita Mountains in the Tucson AMA, the Superstition Mountains in the Phoenix AMA and the Bradshaw Mountains in the Phoenix and Prescott AMAs. Interior chaparral occurs in areas between about 3,500 and 6,000 feet that receive 15 to 25 inches of annual precipitation (Brown, 1982). Typical shrubby species are Mountain Mahogany, Shrub Live Oak, and Manzanita. Chaparral plants are well adapted to drought conditions. Two subdivisions of the Sonoran desertscrub region, the Lower Colorado River Valley subdivision and the Arizona Upland subdivision, dominate all but the Prescott AMA. The Lower Colorado River Valley subdivision is the hottest and driest of the Sonoran desertscrub subdivisions. There is intense competition for water, with plants widely spaced and more concentrated along drainage channels. Characteristic plants include Creosote Bush, Bursage, Saltbush, and mixed, more diverse vegetation along washes and other areas with more water. These areas may include Blue Palo Verde, Ironwood and Jojoba. Also commonly found in the subdivision are several types of cholla and other cacti. (Brown, 1982) The Arizona Upland subdivision borders the Lower Colorado River Valley subdivision and occurs primarily on slopes and sloping plains at elevations of 980 to over 3,000 feet where it merges with interior chaparral or semi-desert grassland. This subdivision receives more precipitation than the other Sonoran desertscrub subdivisions with average annual precipitation between 8 to 16 inches. Vegetation is scrubland or low woodland in appearance with Blue and Foothill Palo Verde, Ironwood, Mesquite and Cat-Claw Acacia as common tree species. Cacti are extremely important in this subdivision including Saguaro, Organ Pipe, cholla and barrel cacti. (Brown, 1982) The occurrence and composition of riparian vegetation has changed along many of the watercourses in the AMA Planning Area, including the Santa Cruz River in the Santa Cruz and Tucson AMAs, the Gila River in the Pinal and Phoenix AMAs, and the Salt and Verde Rivers in the Phoenix AMA. Riparian vegetation has increased in most reaches of the Santa Cruz River upstream from Tucson that have perennial flow from either base flow or sewage effluent, while there has been complete destruction of the riparian ecosystem at Tucson. Cottonwood and willow have increased in density upstream of developments, but in areas where development is up to the river, cottonwood trees have been eliminated. In the late 1990s and early 2000s, die-off of riparian trees occurred at Nogales and near Rio Rico respectively, and may be related to excessive groundwater pumping. North of Tucson, effluent discharge supports a relatively newly established riparian ecosystem. North of Marana, the Santa Cruz River is ephemeral and there is little historic evidence of riparian vegetation with the exception of tamarisk. Tamarisk density may be increasing at some locations (Webb, et al., 2007) Riparian vegetation on the Gila River has significantly declined between Florence in the Pinal AMA and its confluence with the Salt River in the Phoenix AMA due to surface water diversion and groundwater pumpage. This section historically supported reaches of lush, woody riparian vegetation, but now mostly tamarisk and mesquite are found. However, cottonwood has returned along the Gila River near its confluence with the Salt River due to increasing groundwater levels 26 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 and changes in the flow regime of the Salt River. Historic and current groundwater levels are high at the confluence of the Gila and Salt rivers, supporting a cottonwood-willow forest surrounded by “a sea of tamarisk” (Webb, et al., 2007). Effluent discharge from the City of Phoenix and agricultural return flow have created perennial flow and increased riparian vegetation below the confluence, where vegetation is primarily tamarisk and mesquite with small stands of cottonwood-willow (AZGF, 1993). The reservoir system on the Salt River has stabilized the channel in the Phoenix AMA below the dams (except during large flood events) and allowed establishment of native and nonnative (primarily tamarisk) riparian vegetation. Below its confluence with the Verde River and Granite Reef Dam, most of the surface flow of the Salt River is diverted, and the riparian vegetation declines and disappears downstream to the effluent-dependent section near the confluence of the Salt and Gila rivers. Downstream of Bartlett Dam, native and nonnative riparian vegetation has increased along the Verde River due to relatively steady release of water. (Webb, et al., 2007) Vegetation includes cottonwood-willow, tamarisk and mesquite (AZGF, 1993). Concerns about receding riparian areas at some locations have resulted in restoration projects in the Phoenix and Tucson metropolitan areas, including the Rio Salado project in downtown Phoenix in the Phoenix AMA; and the San Xavier Riparian Restoration project on the Tohono O’odham Reservation, south of Tucson in the Tucson AMA. Many of the natural biotic communities in the planning area are threatened by invasive species that interfere with ecosystem function through altering natural fire, nutrient flow and flooding regimes. The most problematic invasive species include: buffelgrass, fountaingrass, Natalgrass, onionweed, Sahara mustard and tamarisk. Numerous agencies and interest groups throughout the planning area have come together to control the spread of these species where feasible, and to educate the public about the threat of these species to ecosystem function. (ASDM, 2008) Although not necessarily caused or exacerbated by invasive species, several major wildfires occurred in the AMA Planning Area during the recent drought years between 2002-2006 (see Figure 8.0-11). The 2003 Aspen fire in the Tucson AMA burned 85,000 acres, including much of the Town of Summerhaven. The 2005 Cave Creek Complex fire, of which a portion is located in the Phoenix AMA, burned 243,950 acres and is the second largest fire in Arizona to date. Both of these fires occurred in areas with Section 8.0 Overview DRAFT 27 Arizona Water Atlas Volume 8 perennial streams and have had documented impacts on peak-flow events. Rainfall two months after the Aspen fire caused runoff to increase three-fold over pre-burn runoff in the Sabino Creek watershed. (Schaffner and Reed, 2007) Increased peak flows can degrade stream channels and make them unstable, increase sediment production, and cause flood damage (Neary, et al., 2003). Arizona Water Protection Fund Programs The objective of the Arizona Water Protection Fund (AWPF) program is to provide grants for the protection and restoration of Arizona’s rivers and streams and associated riparian habitats. Thirtytwo restoration projects in the AMA Planning Area had been funded by the AWPF through 2005. Six projects were funded in the Phoenix AMA for wetland construction, exotic species control, revegetation and general research. One habitat protection project was funded in the Pinal AMA. Six grants in the Prescott AMA funded feasibility studies, general research and stream restoration. In the Tucson AMA fifteen projects, including general research, habitat restoration and exotic species control, were funded. Finally, four research and revegetation projects were funded in the Santa Cruz AMA. A list of projects and project types funded in the AMA Planning Area through 2005 is found in Appendix A of this volume. A description of the program, a complete listing of all projects funded, and a reference map are found in Appendix C of Volume 1. Instream Flow Claims An instream flow water right is a non-diversionary appropriation of surface water for recreation and wildlife use. Fourteen applications for instream flow claims have been filed in the AMA Planning Area. The applications are listed in Table 8.0-1 and are shown on Figure 8.0-12. Claims have been filed in three of the five AMAs, including Phoenix, Tucson and Santa Cruz; and six certificates have been issued, all in the Phoenix AMA. Certificates have been issued for claims on Arnett Creek, Camp Creek, Cave Creek, Hassayampa River, Seven Springs Wash and Sycamore Creek. Claims have been filed for stretches of Queen Creek Wash, Rincon Creek, Sabino Creek and Sonoita Creek.

Sources: 2008,2006 USFWS Source: AZGFAZGF 2007, USFWS 2007 30 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 Threatened and Endangered Species A number of listed threatened and endangered species may be present in the AMA Planning Area. Those listed by the U.S. Fish and Wildlife Service (USFWS) as of January 2008 are shown in Table 8.0-2.2 Presence of a listed species may be a critical consideration in water resource management and supply development in a particular area. The USFWS should be contacted for details regarding the Endangered Species Act (ESA), designated critical habitat, and current listings. As shown on Table 8.0-2 the number and type of endangered or threatened species vary by AMA, with only one in the Prescott AMA and twelve in the Tucson AMA. Habitat encroachment by development and growth in the Tucson AMA, primarily in Pima County, required Pima County to develop a Multi-Species Conservation Plan (MSCP). No such plans affect the other AMAs. The Pima County MSCP was created to comply with the “take” provisions of the ESA.3 Incidental take of a listed species, as the result of carrying out an otherwise lawful activity, is not allowed without a permit from the USFWS.4 The Pima County MSCP includes 55 “Priority Vulnerable Species” and will mitigate the effects of development through preservation of 58% of the land in the permit area as open space. The most recent version of the Pima County MSCP was released in August 2006. (Pima County, 2006a) An incidental take permit has not yet been issued by the USFWS. The Pima County MSCP is part of a larger planning effort known as the Sonoran Desert Conservation Plan (SDCP), which covers 5.9 million acres in Pima County and is focused on six elements: habitat, corridors, cultural resources, mountain parks, ranch conservation and riparian protection. The SDCP planning process began in 1998 as a way to create a science-based conservation plan, update the county’s comprehensive land use plan, and comply with the ESA. The plan directs growth to areas with the least natural, historic, and cultural resource values as well as sets aside sensitive habitat through land acquisitions. As of 2006 the county had built a conservation land reserve of 77,000 acres. (Pima County, 2006b) National Parks, Monuments, Wildlife Refuges and Wilderness Areas The AMA Planning Area contains eleven Wilderness Areas administered by the Bureau of Land Management (BLM), five by the National Forest Service (USFS) and one administered by the National Park Service. The Planning Area also includes one National Wildlife Refuge (NWR), one National Park and four National Monuments (Figure 8.0-13). The national park and one national monument also contain wilderness areas. In total there are over 823,000 acres of protected federal lands in the planning area, accounting for approximately 9% of the land area. The Tucson AMA contains the largest amount of protected areas with almost 372,000 acres. 2 An “endangered species” is defined by the USFWS as “an animal or plant species in danger of extinction throughout all or a significant portion of its range,” while a “threatened species” is “an animal or plant species likely to become endangered whithin the forseeable future throughout all or a significant portion of its range. 3 As defined by the ESA, to take means to “harass, harm, pursue, hunt, shoot, wound, kill, trap, capture or collect, or attempt to engage in other conduct” (16 U.S.C. section 1531[18]) 4 “Incidental take’ is defined by the ESA as a take that is “incidental to, and not the purpose of, the carrying out of an otherwise lawful activity” (50 C.F.R. section 17.22 and 17.32). Section 8.0 Overview DRAFT 31 Arizona Water Atlas Volume 8 32 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 Nine wilderness areas are entirely within the planning area as well as parts of eight others. Wilderness Areas are designated under the 1964 Wilderness Act to preserve and protect the designated area in its natural condition. Designated wilderness areas, their size, basin location and a brief description of the area are listed in Table 8.0-3. The largest protected area in the planning area consists of approximately 259,000 acres of the 496,000-acre Sonoran Desert National Monument. The monument, located in the Phoenix and Pinal AMAs, was established by executive proclamation in 2001 and contains extensive areas of saguaro cactus forest and archeological and historic sites. Two wilderness areas are contained within the monument boundaries. (BLM, 2008) The Ironwood Forest National Monument, located in the center of the planning area in the Tucson and Pinal AMAs, includes over 129,000 acres. An additional 60,000 acres of state trust land and private inholdings are contained within the boundary of the monument but do not have national monument status. Designated in 2000, several endangered and threatened species are found in the monument as well as more than 200 sites dating from the Hohokam period (600 A.D. to 1440 A.D). (BLM, 2008) Other national monuments in the AMA Planning Area include the Hohokam Pima National Monument in the Phoenix AMA, and the Casa Grande Ruins National Monument in the Pinal AMA. Both national monuments protect ancient Hohokam ruins. The village at the Hohokam Pima National Monument, located on the Gila River Indian Community reservation, was recovered with earth in the 1960s and is not open to the public (NPS, 2008a). Casa Grande Ruins National Monument was created as the nation’s first archeological reserve in 1892 and was declared a national monument in 1918. The monument preserves the ancient farming community and its “Great House” (NPS, 2008b). Tumacácori National Historical Park, located in the Santa Cruz AMA, protects three Spanish colonial mission ruins: Tumacácori, Guevavi, and Calabazas, located at three separate sites. Mission San Jose de Tumácacori was established in 1691 and is the main site, located on 310 acres at the town of Tumacácori south of Tubac. The only national park in the planning area, Saguaro National Park, preserves over 83,000 acres in two distinct districts, the Rincon Mountain District and the Tucson Mountain District. The park is located on the east and west sides of Tucson in the Tucson AMA. Saguaro National Park is thought to be home to ten species of threatened, endangered, or sensitive plants. Seventy-five percent of the park is designated as wilderness. (NPS, 2008c) The Buenos Aires National Wildlife Refuge, located in the Tucson AMA, contains over 118,000 acres of habitat for threatened and endangered plants and animals including reintroduced populations of masked bobwhite quail and pronghorn antelope. Concerns about public safety have caused managers to close approximately 3,500 acres of this NWR to the public along the U.S./Mexico border.

Between 1990 and 2000 the population in the AMA Planning Area increased by 38%; population increased an additional 25% between 2000 and 2006. Census data for 2000 show a population of approximately 4.1 million residents and Arizona Department of Economic Security (DES) population projections suggest that the planning area population will more than double by 2030. Historic, current and projected AMA populations are shown in the cultural water demand tables for each AMA in Sections 8.1 - 8.5. The most populous AMA is the Phoenix AMA with approximately 75% of the total planning area population in 2000. The Tucson AMA has the second largest percentage of population in the planning area with 20% in 2000. The 2000 Census populations for each AMA and Indian reservations are shown in Table 8.0-4. AMA population is growing rapidly as Arizona was the second fastest growing state from 2000 to 2006, with a 20.2% population increase. Almost all AMAs experienced growth rates in excess of the state average. During this time period Prescott AMA population increased by 29%, Phoenix AMA population increased by 25% and the Pinal AMA population grew by 68%. The Tucson AMA population increased at a lower rate of 19% during this period.

As shown, there are a number of rapidly growing communities in the planning area. The community of Maricopa in the Pinal AMA grew 1,643% between 2000 and 2006. The community of Marana in the Tucson AMA grew 520% between the years 1990 and 2000 and an additional 125% from 2000 to 2006. Many other communities in the planning area have grown by several hundred percentage points during one or both time periods. Gilbert, Surprise and Goodyear, all in the Phoenix AMA, grew by more than 200% between 1990 and 2000. The Town of Prescott Valley in the Prescott AMA grew by 164% in the same time period. Population Growth and Water Use A variety of regulatory programs and local initiatives affect water use in conjunction with growth within the AMAs. Three examples at the state level that affect multiple AMAs include the Assured Water Supply Program, Growing Smarter legislation, and Community Water System Planning. Locally, communities and counties may have programs or requirements that address growth and water use through impact fees, zoning, planning guidelines and ordinances. Ordinances may include water conservation features in new construction and landscape restrictions; information on these ordinances may be obtained by contacting local planning and zoning departments. In the Tucson AMA, the Sonoran Desert Conservation Plan was initiated by Pima County in Section 8.0 Overview DRAFT 37 Arizona Water Atlas Volume 8 1998 in response to conservation needs of rare species, and as an effort to balance growth and environmental concerns. The 50-year plan covers 59 million acres within Pima County. The SDCP was incorporated into Pima County’s comprehensive land use plan in 2001 and addresses issues such as land use and water availability. The Groundwater Code established within each AMA a five-member Groundwater Users Advisory Council (GUAC). Members of the councils are appointed by the governor to represent the users of groundwater in the AMA, and on the basis of their knowledge, interest, and experience with problems relating to the development, use and conservation of water. The GUACs provide recommendations on groundwater management programs and policies to the AMA area director, and to the Director of the Department. A number of citizen-based advocacy groups, and government-sponsored advisory groups, also provide input into the growth and water use decision-making process within the AMA Planning Area. These groups may include municipal and regional water users associations; watershed groups; county water advisory councils; non-profit conservation groups; water augmentation authorities; and county associations of government. Assured Water Supply Program The Department’s Assured Water Supply (AWS) program, created as part of the 1980 Groundwater Management Code, is designed to preserve groundwater resources and to promote long-term water supply planning in the AMAs. This is accomplished through regulations that limit the use of groundwater by new subdivisions that require a “Certificate” of AWS and by “Designated” Water Providers that have demonstrated an AWS for their entire service area. The AWS Program also provides consumer protection by requiring developers to demonstrate that sufficient water supplies are available for new subdivisions prior to sale. Every developer proposing to build a new subdivision is required to demonstrate an AWS that will be physically, legally, and continuously available for the next 100 years before the developer can record plats or sell parcels. The Arizona Department of Real Estate will not issue a Public Report, which allows the developer to sell lots, without a demonstration of an AWS. In 1995, the Department adopted AWS Rules to implement the AWS statutes. An important component of the AWS Rules is the requirement to demonstrate that renewable water supplies will be used rather than mined groundwater. This requirement did not apply to the Prescott AMA until 1999 when the AMA was declared to no longer be in a safe-yield condition. The Santa Cruz AMA was established July 1, 1994 near the end of the period when the AWS Rules were being drafted. Consequently, it was not possible to include rule provisions that applied to the management goal of the Santa Cruz AMA at that time since goal criteria had not been developed. Although the general Rule provisions apply, the Department is still developing specific AWS Rules for the Santa Cruz AMA where relatively limited groundwater storage capacity directly influences the availability of water supplies and where the hydrologic situation may affect the course of population growth in this AMA. 38 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 Table 8.0-6 Designated water providers in the AMA Planning Area Water Provider Name Active Management Area County Designation No. Date Application Received Date Designation Issued Apache Junction Water Facility Phoenix Pinal 26-400989.0000 06/09/03 02/01/05 2,769 2011 Chapparal City Water Company Phoenix Maricopa 26-401242.0000 02/11/04 04/07/04 8,000 2014 City of Avondale Phoenix Maricopa 86-002003.0001 06/11/07 02/04/08 21,186 2010 City of Chandler Phoenix Maricopa 26-002009.0000 02/15/95 12/31/97 63,615 2010 City of El Mirage Phoenix Maricopa 26-400054.0000 03/22/99 11/02/99 7,695 2010 City of Glendale Phoenix Maricopa 26-002018.0000 03/15/95 09/25/97 57,074 2010 City of Goodyear Phoenix Maricopa 26-402090.0000 04/07/06 01/27/08 15,940 2010 City of Mesa Phoenix Maricopa 26-002023.0000 05/28/96 09/19/97 105,061 2010 City of Peoria Phoenix Maricopa 26-400679.0000 01/18/02 10/17/02 39,325 2010 City of Phoenix Phoenix Maricopa 26-002030.0000 10/11/96 12/31/97 356,521 2010 City of Scottsdale Phoenix Maricopa 26-400619.0000 10/11/01 04/25/02 105,986 2008 City of Surprise Phoenix Maricopa 26-300431.0000 11/11/97 09/07/99 20,334 2010 City of Tempe Phoenix Maricopa 26-002043.0000 03/27/97 12/31/97 70,462 2010 Johnson Utilities Phoenix Pinal 26-400665.0000 12/26/01 08/12/03 5,633 2011 Town of Gilbert Phoenix Maricopa 26-402208.0000 06/19/06 10/30/07 70,954 2010 City of Casa Grande Pinal Pinal 26-400728.0000 05/06/02 07/21/03 4,113 2013 City of Eloy Pinal Pinal 26-402148.0000 05/10/06 02/20/07 49,159 2015 Johnson Utilities Pinal Pinal 26-401382.0000 05/26/04 10/14/05 551 2007 Santa Cruz Water Company Pinal Pinal 26-402008.0000 01/24/06 12/27/07 23,979 2013 Town of Florence Pinal Pinal 26-401284.0000 03/12/04 01/25/05 12,310 2014 Projected or Year of Projected Annual Estimated or Annual Demand (af/yr) Estimated Demand City of Prescott Prescott Yavapai 26-401501.0000 09/02/04 09/16/05 14,350 2014 Baca Float Water Company, Inc.

This rule change, which took effect on October 1, 2007, substantially reduced the volume of groundwater that can be used without replenishment by new developments, from close to 100% under the old rules to as little as 10% under the new rules. Under the AWS Rules, the developer can prove a 100 year water supply by satisfying the requirements to obtain a Certificate of AWS or by a written commitment of service from a provider with a Designation of AWS. The AWS Rules list in detail what an applicant for a Certificate of AWS or a Designation of AWS must demonstrate. In addition to securing a water supply that is physically, legally, and continuously available for the next 100 years, the developer, in order to obtain a Certificate, must prove that the supply is of sufficient quality and is consistent with the AMA management goal and management plan. Finally, the developer must demonstrate the financial capability to construct any necessary water storage, treatment, and delivery systems. Water providers seeking a Designation of AWS must demonstrate a 100-year water supply for their entire service area for both current and committed demand, as well as projected demand. A list of current Designated water providers in the planning area can be found in Table 8.0-6. Before the AWS program was created in 1980, the Adequate Water Supply program was effective statewide. This program was created in 1973 as a consumer protection program and is still in effect outside the AMAs. If a developer can successfully demonstrate that water of sufficient quality will be physically, legally and continuously available for the next hundred years, the Department will issue a Water Adequacy Report with a determination that the water supply is adequate. If the Department determines that there is an inadequate water supply, the developer can still sell the lots but must disclose this fact to potential buyers. Because the Adequate Water Supply program was in effect in the planning area prior to 1980, some Water Adequacy Reports issued for older developments in the AMAs exist. Prior to obtaining a Certificate of AWS, developers also have the option to obtain an Analysis of AWS (Analysis). An Analysis is generally used to prove that water will be physically available for master planned communities but may be used to demonstrate other criteria required for a Certificate of AWS. An applicant for an Analysis must demonstrate that one or more of the requirements for an AWS are met, but need not demonstrate that all have been met. If an Analysis is issued for groundwater, it reserves a specific volume of water for 10 years for the specific property that is the subject of the Analysis. However, an Analysis cannot be used to obtain a Public Report and must be followed by a complete demonstration of all the criteria to obtain a Certificate of AWS. A summary of the planning area’s AWS determinations including AWS Certificates (27’s), Analysis of AWS (28’s), Water Adequacy Reports (53’s) and AWS Designations (26’s) can be found in Table 8.0-7. Detailed information on individual subdivisions are found in the AMA Assured Water Supply sections, 8.1.9- 8.5.9. Growing Smarter Four out of the five counties in the planning area have requirements under the Growing Smarter Plus Act of 2000 (GSP Act). The GSP Act requires that counties with a population greater than 125,000 40 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 Table 8.0-7 Assured Water Supply determinations in the AMA Planning Area Phoenix AMA Pinal AMA Prescott AMA Santa Cruz AMA Tucson AMA Total AWS Certificates 865 192 104 34 201 1396 Analysis of AWS 18 18 2 6 4 48 Water Adequacy Reports 196 16 9 32 90 343 AWS Designations 15 5 1 2 9 32 Note: Totals do not include change of ownership or re-issuance of AWS Certificates (2000 Census) include planning for water resources in their Comprehensive Plans. Counties in the planning area that must meet this requirement are Maricopa, Pinal, Pima and Yavapai. Santa Cruz is the only county in the planning area with a population less than 125,000 residents. The GSP Act also requires that 30 communities in the AMAs include a water resources element in their general plan. These communities are: Phoenix AMA Pinal AMA Prescott AMA Santa Cruz AMA Tucson AMA Apache Junction Avondale Buckeye Cave Creek Chandler El Mirage Fountain Hills Gilbert Glendale Goodyear Mesa Paradise Valley Peoria Phoenix Queen Creek Scottsdale Surprise Tempe Casa Grande Eloy Florence Maricopa City Chino Valley Prescott Prescott Valley Nogales Marana Oro Valley Sahuarita Tucson Section 8.0 Overview DRAFT 41 Arizona Water Atlas Volume 8 As of December, 2007, all but Nogales had complied with the general plan requirement. Plans must consider water demand and water resource availability in conjunction with growth, land use and infrastructure. These plans may contain useful water resource information. Community Water System Planning Beginning in 2007, all community water systems in the state are required to submit annual water use reports and system water plans to the Department. The reports and plans are intended to reduce community water systems’ vulnerability to drought, and to promote water resource planning to ensure that water providers are prepared to respond to water shortage conditions. Community water systems located within the AMA Planning Area have been reporting their annual water use to the Department and have been regulated under the Department’s mandatory municipal conservation program since the early 1980s. They are now subject to the system water plan requirements, though exemptions from some components of the plans may apply for large municipal providers, as well as providers with an AWS designation. The Department is working to establish local drought impact groups (LDIGs) throughout the state. LDIGs are county-level groups that will coordinate drought preparedness at the local level. They are led by the county extension agent and county emergency manager, and have three main objectives: collect and report drought impact information, coordinate drought public awareness, and develop and implement local mitigation and response options. Participants include municipal and private water providers, irrigation districts, tribal governments, local non-governmental organizations, state/federal agencies, and other interested citizens. LDIGs have been Figure 8.0-14 Water supply utilized in the AMA established in Cochise, Yavapai, Santa Planning Area Cruz, Pinal, Pima, Graham, Greenlee, and Navajo Counties. Formation of LDIGs Effluent in the remaining counties are planned for 5% 2008-2009. 8.0.6 Water Supply Water supplies in the AMA Planning Area include Central Arizona Project (CAP) water, surface water, groundwater and effluent. As shown in Figure 8.0-14, on average more than half of the annual water demand in the planning area from 2001-2003 was met with non-groundwater supplies. Non-groundwater or renewable supplies in the planning area are comprised mainly of CAP water and surface water diverted from the Salt, Verde, Gila, Agua Fria or Santa Cruz rivers. Effluent is also a growing non-groundwater source used in the planning area. Non-groundwater supplies were the primary water supply source in the Pinal and Phoenix AMAs between 2001-2003. In the Pinal AMA, 42 CAP 31% Groundwater 44% Surface Water 20% Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 53% of the average annual water demand between 2001-2003 was met with a non-groundwater source and 47% of the demand was met with groundwater. The Phoenix AMA also relies heavily on nongroundwater sources. 62% of its average annual demand in 2001-2003 was met with non-groundwater sources and 38% of its demand was met with groundwater. In 2001-2003, an average of 45% of the planning area water demand was met with groundwater. The Prescott AMA used solely groundwater supplies with the exception of small amounts of effluent during this period. The Santa Cruz AMA uses a combination of groundwater, and surface water from the younger alluvium that is withdrawn from wells and collectively considered groundwater. Between 2001 and 2003, the Tucson AMA used approximately 73% groundwater and 27% non-groundwater supplies to meet demands. The percentage of non-groundwater sources, primarily CAP, used in the Tucson AMA has increased rapidly over the last five years due to the increased recharge and recovery capacity in the municipal sector. Central Arizona Project Water The primary non-groundwater source in the planning area is CAP water. The CAP was constructed to annually deliver 1.5 maf of Arizona’s allocation of Colorado River water to Pima, Pinal and Maricopa counties through a series of canals and pumping stations. (See Figure 8.0-15) The project is 336 miles long and lifts Colorado River water 2,400 feet to its final destination just south of the City of Tucson. Water is withdrawn at Lake Havasu at the Mark Wilmer Pumping Plant. It then crosses the Parker, Ranegras Plain and Harquahala basins via the Hayden-Rhodes Aqueduct to the CAP service area in central and southern Arizona. The CAP canal enters the planning area on the western side of the Phoenix AMA and runs toward the east and southeast across much of the AMA. A significant portion of CAP water is stored in Lake Pleasant behind New Waddell Dam at the northern edge of the Phoenix AMA. It then travels in a southerly direction and enters the Pinal AMA north of Florence, crosses the northeastern portion of the AMA and enters the Tucson AMA near Picacho Peak. The CAP canal terminates at Pima Figure 8.0-15 Central Arizona Project system map (Source: CAP, 2008) Mine Road in the Tucson AMA just south of the San Xavier District of the Tohono O’odham Nation. Turnouts from the CAP aqueduct connect it to municipal water treatment plants and irrigation district canals for distribution. CAP water is used both directly and Section 8.0 Overview DRAFT 43 Arizona Water Atlas Volume 8 indirectly through the Department’s recharge program, in the Phoenix, Pinal and Tucson AMAs. CAP was first used in the planning area in 1985. There are three main CAP user categories: municipal and industrial (M&I), non-Indian agricultural and Indian. Almost all non-Indian agricultural subcontracts have been declined or terminated and CAP water is used pursuant to the Department’s recharge program discussed below. The status of CAP subcontracts as of March 2008 is found in Appendix B. According to the status report, subcontract totals were: M&I Subcontracts Indian Contracts Non-Indian Agricultural Subcontracts Currently Uncontracted Water Other Under Contract 620,678 acre-feet 555,806 acre-feet 9,026 acre-feet 155,787 acre-feet 73,703 acre-feet To encourage the direct use of renewable water supplies, the recharge program restricts the type of water that may be stored long-term to renewable sources that cannot be used directly. Persons who wish to store water through the recharge program must apply to the Department for permits. There are two types of facilities and associated permits; Underground Storage Facility (USF) Permits and Groundwater Savings Facility (GSF) Permits. In addition, a Water Storage (WS) Permit (A.R.S. § 45-831.01) allows the permit holder to store water at a USF or a GSF and a Recovery Well (RW) Permit (A.R.S. § 45-834.01) allows the permit holder to recover long-term storage credits or to recover stored water annually. CAP water use on non-Indian agricultural land is pursuant to GSF Permits (A.R.S. § 45-812.01), which allows the permit holder to deliver a renewable water supply, called “in lieu” water, to a recipient (farm) who agrees to replace groundwater pumping with in lieu water, thus creating a groundwater savings. The permit holder accrues recharge credits which can be recovered later from a well elsewhere in the AMA (or INA). When withdrawn, the water retains the character of the water that was recharged at the GSF. A USF Permit (A.R.S. § 45-811.01) allows the permit holder to operate a facility that stores water in the aquifer in one of two ways. A constructed underground storage permit allows water to be stored by using some type of constructed device, such as an injection well or percolation basin. A managed underground storage facility permit allows water to be discharged to a naturally watertransmissive area such as a streambed where the water percolates into the aquifer without the assistance of a constructed device. Most of the water delivered to recharge facilities in the AMA Planning Area is CAP water with lesser amounts of effluent and surface water. In 2005, over 423,000 acre-feet of CAP water, 91,600 acre-feet of effluent and 11,400 acre-feet of surface water was delivered to USFs and GSFs, for a total of over 526,000 acre-feet delivered. As of 2005, more than 3.7 maf of long term storage credits had been accrued in the AMA Planning Area. The location of GSF and USF sites and facility information is shown on maps and tables in the groundwater conditions section for each AMA. 44 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 Surface Water In addition to CAP water, the principal sources of surface water in the planning area are the Salt and Verde rivers. Most of this water is appropriated to shareholders of the Salt River Valley Water Users Association or Salt River Project (SRP). The SRP was established in 1903 as the nation’s first multipurpose reclamation project. Today, it is the nation’s third largest public power utility and one of the state’s largest water suppliers. Working with other agencies, the SRP manages or assists with the management of seven dams. This reservoir system is utilized in conjunction with about 250 groundwater wells to provide water through 131 miles of canal to a 2,900 square mile service area that delivers more than 1 maf of water annually to its customers.. The SRP encompasses portions of the East Salt River Valley and West Salt River Valley sub-basins in the Phoenix AMA, including portions of Glendale, Peoria, Phoenix, Scottsdale, Tempe, Tolleson, Chandler, Gilbert, and Mesa. (SRP, 2008) Historically SRP water was used predominantly for agricultural irrigation; now a large portion of the project’s service area is urbanized. In addition to the SRP, the Roosevelt Water Conservation District and the Buckeye Water Conservation District use surface water from the Salt and Verde rivers. The Gila River is also an important water supply in both the Phoenix and Pinal AMAs where it is used primarily for agricultural irrigation. Water is diverted for the San Carlos Irrigation Project (SCIP) at Ashurst-Hayden Diversion Dam located 12 miles east of Florence in the Pinal AMA. The dam, completed in 1922, consists of diversion works and is not a storage or flood control facility. Diverted water is conveyed to the San Carlos Irrigation and Drainage District (SCIDD), located in the Pinal AMA, consisting of approximately 200 miles of unlined main and lateral canals and 40 miles of canals owned jointly with the SCIP (ADWR, 1998). In addition to agricultural uses, SCIDD delivers Gila River water mixed with groundwater for landscape irrigation to subdivisions, schools, parks, Casa Grande, Coolidge and Florence (ADWR, 1999b). The SCIP also delivers Gila River water to tribal lands within the Gila River Indian Community located in the Phoenix and Pinal AMAs. The Buckeye Water Conservation and Drainage District in the West Salt River Subbasin of the Phoenix AMA also uses Gila River water as part of its water supply. Maricopa Water District (MWD) in the West Salt River Valley Sub-basin uses a combination of CAP and Agua Fria River water stored in Lake Pleasant behind New Waddell Dam, which was completed in 1992. This water is delivered to the MWD service area via the 33-mile Beardsley Canal. MWD owned and operated Waddell Dam, the original storage and flood control structure on the Agua Fria River, which was breached and inundated by the enlarged Lake Pleasant. (ADWR, 1998) A few additional sources of surface water are utilized in the planning area. Santa Cruz River water is diverted for agricultural irrigation by the Central Arizona Irrigation and Drainage District in the Eloy Sub-basin of the Pinal AMA. In the Tucson AMA, surface water diverted from Cienega Creek is used for turf irrigation at Del Lago Golf Course at Vail and springs are the water supply for the community of Summerhaven, located in the Santa Catalina Mountains. In the Prescott AMA, the City of Prescott has acquired surface water rights to water stored at Watson Lake and Willow Creek reservoirs from the Chino Valley Irrigation District (CVID). Under the agreement the City maintains the lakes for recreational purposes and releases approximately 1,500 Section 8.0 Overview DRAFT 45 Arizona Water Atlas Volume 8 acre-feet per year for recharge, which it recovers on an annual basis. As part of the agreement the City of Prescott annually provides up to 1,500 acre-feet of recovered effluent credits to CVID members for irrigation. While the City of Prescott holds surface water rights to water stored at Lynx and Upper Goldwater reservoirs, this water is not used as a water supply. Groundwater Groundwater is an important water supply in the planning area. It is the primary water source in the Prescott and Santa Cruz AMAs, as these AMAs do not have access to CAP water. Water supplies are managed jointly as “groundwater” in the Santa Cruz AMA due to the close hydrologic relationship of surface water, groundwater and effluent. Up until relatively recently, the Tucson AMA also relied primarily on groundwater to meet demand. Groundwater is also a vital water supply for the Phoenix and Pinal AMAs, although currently, surface water supplies surpass groundwater supplies in both AMAs. Groundwater is a relatively abundant water supply with maximum well yields in all five AMAs exceeding 4,000 gpm. As a result of long term groundwater pumping in the AMAs, moderate to severe regional and localized water level declines have occurred. Over time, groundwater declines can lead to increased pumping costs, decrease in water quality, riparian damage, land subsidence and land fissuring, all of which have occurred in the planning area. In the last two decades localized groundwater level rises have also occurred at some locations. Localized water level rises are primarily due to retirement of agricultural lands, use of CAP water in lieu of groundwater and a growing number of underground storage projects. All groundwater used in the AMAs is currently pumped from within the AMAs. The Groundwater Transportation Act of 1991 restricts the transportation of groundwater from non-AMA groundwater basins to AMAs; however, there are a few exceptions. Specific statutes allow the transportation of groundwater from the Butler Valley, Harquahala and McMullen Valley basins and the Big Chino sub-basin into AMAs. For example, the City of Phoenix owns 14,000 acres of agricultural land in the McMullen Valley Basin allowing it to transport up to 6 maf of groundwater into the Phoenix AMA. The City of Scottsdale has also applied to the Department to transport 3,645 acre-feet of groundwater per year from historically irrigated land in the Harquahala Basin. Groundwater transportation from the Big Chino Sub-basin of the Verde River Basin, northwest of the Prescott AMA, represents the largest source of alternative water supply currently available for municipal water users within the Prescott AMA. Under A.R.S. § 45-555(E), the City of Prescott may withdraw an amount not to exceed 14,000 acre-feet per year. The Director has issued an advisory opinion that the amount that may be withdrawn by the City of Prescott is 8,717 acre-feet; however, a final determination has not been made. No water may be withdrawn for transportation into the AMA pursuant to this statute until the Director has made a final determination. Additionally, the statute allows for cities and towns to withdraw groundwater associated with historically irrigated acres (HIA) for transportation into the Prescott AMA. The Department will make a determination regarding the volume of water that can be transported from HIA lands after an application in submitted by a city or town. In general, the allotment associated with HIA is 3 acre-feet per acre per year. 46 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 In order to improve available groundwater supply information, the Department has established automated groundwater monitoring sites that record water levels in wells. This information is available through an interactive map on the Department’s website (www.azwater.gov/dwr/). These devices are generally placed in areas that the Department wishes to monitor closely, such as areas of growth, subsidence and areas affected by drought. Currently there are 70 monitoring sites in the planning area: 34 in the Phoenix AMA; 16 in the Prescott AMA; 11 in the Tucson AMA; five in the Santa Cruz AMA; and four in the Pinal AMA. Index well hydrographs, which display historic water level conditions, are available through an interactive map on the same website for 830 wells in the planning area. Information on major aquifers, well yields, estimated natural recharge, aquifer flow direction, and water level changes are found in groundwater data tables, groundwater condition maps, hydrographs and well yield maps for each AMA in Sections 8.1.6 through 8.5.6. Effluent Effluent, also referred to as reclaimed water, is a growing non-groundwater supply in the AMA Planning Area, accounting for approximately 5% of the annual supply during the 2001-2003 time period. Since effluent production is tied directly to population, population growth generally leads to increased effluent supply. However, lack of infrastructure to deliver effluent to potential users is often a limiting factor. The Phoenix and Tucson AMAs generate the majority of the effluent in the planning area, which is used by agricultural, municipal and industrial sectors. Many municipalities, as well as private entities in the planning area, recharge effluent in permitted basins and streambeds. This storage in turn earns the entity recharge credits that it can either pump from the ground at a later date through a permitted recovery well, or use towards assured water supply certificates or designations. The option of recharge is often favored by entities as a way of using the effluent if direct use is not possible due to the lack of a distribution system. There is increasing interest in effluent as a water supply as growth continues and other renewable water sources become more extensively used. Some utilities, for example Tucson Water, Phoenix, Prescott and Scottsdale, have made substantial investments in effluent reuse. Recently, Global Water Resources, a private water and wastewater utility, is promoting reuse technology at new development in Maricopa where its water center uses non-potable water for irrigation and toilet flushing. Most of the effluent in the Phoenix AMA is generated at the 91st Avenue WWTP. The treatment plant processes approximately 139,000 acre-feet of wastewater annually from much of Glendale, Mesa, Phoenix, Scottsdale, and Tempe, who co-own the facility as part of a multi-city partnership known as SROG, the Sub-regional Operating Group. A large portion of the effluent is used at the Palo Verde Nuclear Generating Station for cooling purposes. Unused effluent from the plant is discharged into the Salt and Gila Rivers, supporting perennial flow and flowing out of the AMA. Effluent is also a water supply for agricultural irrigation. Effluent generated from Phoenix’s 23rd Avenue WWTP is used to irrigate crops in the Roosevelt Irrigation District and effluent from Chandler’s Lone Butte WWRP is used for irrigation on the Gila River Indian Reservation. In addition to industrial and agricultural uses, effluent is used for landscape and golf course watering. Section 8.0 Overview DRAFT 47 Arizona Water Atlas Volume 8 Major cities in the Phoenix AMA and the City of Tucson in the Tucson AMA have extensive distribution systems for delivery of reclaimed wastewater to golf courses, parks and schools. In the Pinal AMA, Casa Grande, Coolidge, Eloy and Florence all have municipal WWTPs. These plants deliver treated effluent for a variety of purposes, including agricultural irrigation, golf course watering, and power generation. Florence and Eloy also have permitted underground storage facilities for recharging effluent. The City of Maricopa’s wastewater needs are handled by a private utility and the effluent is used for watering turf and filling subdivision lakes. There are several other WWTPs serving unincorporated communities. Effluent from these facilities is used for golf course watering, and in some cases the excess is recharged at underground storage facilities (see Table 8.2-7). Effluent is an important water supply in the Tucson AMA where it meets approximately 3% of the total AMA water demand. The City of Tucson operates an extensive reclaimed water system that has been in operation since the early1980s. The system consists of almost 160 miles of pipe, 33 mgd of production capacity, 15 million gallons of storage capacity and four supply sources including the Tucson Water Reclaimed Water Treatment Plant, a treatment wetlands and a managed underground storage facility. The system extends throughout the Tucson water service area and extends into northeast Marana near the Tortolita Mountains and interconnects to the Oro Valley system where it is used for golf course irrigation in the Town of Oro Valley. Reclaimed water is delivered to approximately 900 sites in the Tucson Water service area including 14 golf courses, 35 parks, 46 schools and more than 700 single family homes. (Tucson Water, 2007) Three communities in the Prescott AMA have permitted recharge facilities that receive effluent: the City of Prescott, the Town of Prescott Valley and the Town of Chino Valley. Effluent availability at the Town of Chino Valley is currently limited as the Town is largely unsewered. However it is in the process of constructing a centralized sewer system to serve new and existing developments. Effluent is a source of supply both directly and through recharge and recovery for three golf courses, a community park, and a sand and gravel operation in Prescott, as well as for a golf course at Prescott Valley. Effluent stored by the City of Prescott is recovered by CVID for agricultural irrigation. Effluent stored by Prescott Valley is not currently recovered. The Nogales International Wastewater Treatment Plant (NIWWTP) is the primary treatment facility in the Santa Cruz AMA. It treats over 16,000 acre-feet of sewage from both Nogales, Arizona and Nogales, Sonora, which is currently discharged to the Santa Cruz River. Several smaller “package” treatment plants provide treatment to developments within the AMA, but do not provide a significant amount of useable effluent. Contamination Sites Sites of environmental contamination may impact the use of some water supplies. An inventory of Department of Defense (DOD), Resource Conservation and Recovery Act (RCRA), Superfund, Water Quality Assurance Revolving Fund (WQARF), Voluntary Remediation Program (VRP) and Leaking Underground Storage Tank (LUST) sites was conducted for the planning area. Table 8.0-8 provides a summary of contamination sites, by cleanup program, for each AMA. Tables listing the 48 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 contaminant and affected media as well as maps showing the location of all contamination sites can be found in the AMA Water Quality sections.

The majority (39) of these sites are located in the Phoenix AMA. The VRP is a state administered and funded voluntary cleanup program. Any site that has soil and/or groundwater contamination, provided that the site is not subject to an enforcement action by another program, is eligible to participate. To encourage participation, ADEQ provides an expedited process and a single point of contact for projects that involve more than one regulatory program (Environmental Law Institute, 2002). There are 14 RCRA sites in the AMA Planning Area, 10 in the Phoenix AMA, two in the Tucson AMA and one each in the Pinal and Santa Cruz AMAs. The RCRA program regulates the management of hazardous waste handlers which includes generators, transporters and facilities for treatment, storage and disposal (ADEQ, 2002). The sites listed in Table 8.0-8 and in the AMA Water Quality sections are RCRA corrective action sites where contamination of groundwater and/ or soil has occurred due to improper handling of hazardous waste. Two DOD sites are located in the AMA Planning Area, the 161st Air National Guard site in the Phoenix AMA and the Davis-Monthan Air Force Base site in the Tucson AMA. DOD sites listed in the AMA Water Quality sections are contamination sites that are located at active duty bases, bases being closed under the Base Realignment and Closure regulations or Formerly Used Defense sites that are eligible for funding under the Installation Restoration Program overseen by ADEQ (ADEQ, 2008). There are 19 WQARF sites and five Superfund sites in the AMA Planning Area. These sites are located in the Phoenix and Tucson AMAs. WQARF is a state administered funding mechanism created to support hazardous substance cleanup efforts. Superfund is the federal government’s program, administered by the Environmental Protection Agency (EPA), to clean up the most contaminated hazardous waste sites across the country. (ADEQ, 2008) Almost all WQARF and Superfund sites in the planning area involve Trichloroethylene (TCE) and/or Tetrachloroethene (PCE) contamination. One Superfund site, 19th Avenue Landfill in the Phoenix AMA, was removed from the National Priorities List (NPL) of Superfund sites in 2006 after the EPA and ADEQ determined that no further cleanup activities were necessary (ADEQ, 2006). Section 8.0 Overview DRAFT 49 Arizona Water Atlas Volume 8 There are 5,697 active LUST sites in the planning area. Four thousand and forty-two sites are located in the Phoenix AMA, 292 in the Pinal AMA, 180 in the Prescott AMA, 26 in the Santa Cruz AMA and 1,157 in the Tucson AMA. 8.0.7 Cultural Water Demand Total cultural water demand in the AMA Planning Area averaged approximately 3,750,800 acrefeet per year during the 2001-2003 time period; approximately 52% of the total demand in Arizona. Total non-Indian and Indian demand, by water source and water demand sector for each AMA, is shown in Figure 8.0-16 and Table 8.0-9. Tribal demand and non-Indian municipal, agricultural and industrial sector demand are discussed later in this section. Tribal and non-tribal demands are discussed separately because non-Indian water use in AMAs is regulated under the Groundwater Code which requires annual reporting of water use by all groundwater rightholders, compliance with mandatory conservation requirements, and other regulations. As a consequence, these data are generally reported in Departmental and other publications. As shown in Figure 8.0-16, cultural water demands vary widely between the AMAs due to differences in geographic area, population, land use and available water supplies. Total cultural water demand is the highest in the Phoenix AMA and lowest in the Santa Cruz AMA with an average annual total demand of 2,335,200 acre-feet and 23,800 acre-feet, respectively. Municipal demand accounted for 34% of the cultural water demand with approximately 1,258,200 acre-feet of average annual demand during the 2001-2003 time period. Municipal demand includes water delivered by a water provider and water withdrawn from domestic (exempt) wells.5 As would be expected, the Phoenix AMA accounts for the largest (81%) of the total municipal demand in the planning area. Across the AMAs, 61% of the municipal demand is met with CAP, surface water and effluent supplies. As with the agricultural sector, this source of supply differs between AMAs. The Phoenix AMA meets over 71% of its municipal demand with CAP, surface water and effluent supplies while the other AMAs use primarily groundwater. The agricultural sector is the highest demand sector with 2,211,000 acre-feet or approximately 59% of the total cultural demand. Agricultural demand exists within all AMAs but the volumes vary significantly between them. The largest annual average agricultural demand is in the Phoenix AMA at 1.1 maf (47% of total Phoenix AMA demand) and the smallest is in the Prescott AMA with 6,100 acre-feet (25% of total Prescott AMA demand). The sources of water used to meet demand also vary between the AMAs. Agricultural demand in the Prescott AMA is met with groundwater and recovered effluent credits; surface water use has recently ceased. In the Phoenix and Pinal AMAs, more than half of the agricultural demand is met with CAP, surface water and effluent supplies. In Tucson, approximately 27% of the agricultural demand is met with CAP water and the remainder by groundwater. Industrial demand accounted for the remaining 7% of the annual cultural water demand within the planning area for the 2001-2003 time period. Although groundwater is the predominant water supply for industrial uses in all AMAs, significant volumes of effluent are used in the Phoenix and 5 An exempt well is a well having a pump capacity of not more than thirty-five gallons per minute. Within an AMA, a person may withdraw groundwater from an exempt well for a non-irrigation use without a groundwater right or permit. 50 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 Eff. 32% CAP 3% GW 54% Figure 8.0-16 FigureDemand 8.0-X AMA Water by AMA Water Demand Sector and Water Source by Sector and Water Source Avg. 2001-2003 SW 11% Industrial 9% Avg. 2001-2003 Agricultural 47% Eff. 6% Municipal 44% Eff. 2% CAP 27% SW 25% GW 30% CAP 30% GW 42% SW 38% Phoenix AMA (62%) CAP 1% 2,335,200 af Eff. 1% GW 99% Industrial 16% Eff. 6% CAP 16% CAP 27% GW 78% SW 3% GW 73% CAP 1% CAP 11% GW 85% GW 85% Municipal 3% Agricultural 31% Municipal 53% CAP 49% Eff. 14% Industrial 1% GW 45% Tucson AMA (9%) 339,300 af Agricultural 96% SW 6% Industrial 6% GW 100% Industrial 6% Ag 25% Eff.

The nature of the industrial demand differs between the AMAs. Water use by turfrelated facilities is the largest industrial demand in the Santa Cruz, Prescott and Phoenix AMAs. In the Tucson AMA, mining accounts for almost 70% of the industrial demand. In the Pinal AMA, dairies and feedlots are the largest industrial demand category, accounting for 47% of the industrial total. Tribal Water Demand With the exception of the Santa Cruz AMA, there are tribal lands within all AMAs. Tribal communities, in alphabetical order, are: Ak-Chin Indian Community (Pinal AMA); Fort McDowell Yavapai Nation (Phoenix AMA); Gila River Indian Community (Phoenix and Pinal AMAs); Pascua Yaqui Tribe (Tucson AMA); Salt River Pima-Maricopa Indian Community (Phoenix AMA); Tohono O’odham Nation (Pinal and Tucson AMAs); and Yavapai-Prescott Indian Tribe (Prescott AMA). Annual tribal demand is approximately 371,100 acre-feet per year. Ninety seven percent of tribal demand is agricultural irrigation. Groundwater meets about 39% of all tribal demand with large proportions of surface water (31%) and CAP water (30%) also utilized. Ak-Chin Indian Community The Ak-Chin Indian Community is a 21,480-acre area located entirely within the Pinal AMA in northwest Pinal County approximately 50 miles south of the Phoenix metropolitan area. The community has approximately 750 tribal members comprised of both the Tohono O’odham and Pima people (2000 Census). The community includes a 109-acre industrial park and 15,000 acres of irrigated fields (ITCA, 2008). Additionally, in 1994, the Ak-Chin Community entered into a management agreement to construct the Harrah’s Phoenix Ak-Chin Casino located within the community. The Ak-Chin Indian Community was originally allocated 58,300 acre-feet of CAP water in 1983. Pursuant to the community’s water rights settlement in 1984, it is entitled to 75,000 acre-feet of Colorado River water in a normal year, 85,000 acre-feet in a surplus year and not less than 72,000 acre-feet in a shortage year. The intended use of the CAP water is irrigation (CAP, 2008). In addition to on-reservation use of CAP water, the Ak-Chin Indian Community has entered into long term CAP lease agreements, primarily with Anthem. In 2007, approximately 7,000 acre-feet of CAP lease water was used by off-reservation users. Fort McDowell Yavapai Nation The almost 25,000-acre Fort McDowell Yavapai reservation is located in northeastern Maricopa County approximately 23 miles northwest of Phoenix. The reservation is bisected by the Verde River and is located entirely within the Phoenix AMA. The Nation has slightly more than 900 members comprised of the Yavapai and Apache people (2000 Census). There are a number of commercial operations within the reservation. The Fort McDowell Casino is a gaming facility located adjacent to a 247-room Radisson Resort and Conference Center and the 18-hole We-KoPa Golf Club. Fort McDowell Yavapai Materials is a sand and gravel facility that has been in operation since 1980. The Fort McDowell Tribal Farm includes 2,000 irrigated acres of alfalfa, pecans and citrus. Section 8.0 Overview DRAFT 53 Arizona Water Atlas Volume 8 Recreational activities associated with the Verde River and Fort McDowell Adventures are other tribal enterprises (NAU, 2008; ITCA, 2008). The Fort McDowell Yavapai Nation was originally allocated 4,300 acre-feet of CAP water in 1983. Pursuant to the tribe’s water rights settlement in 1990, the nation now has 18,233 acre-feet of CAP allocation with the intended use identified as tribal homeland (CAP, 2008). In 2007, the City of Phoenix executed a long-term lease of 4,300 acre-feet/year of the Fort McDowell Yavapai Nation entitlement. Gila River Indian Community The 373,000-acre Gila River Indian Community (GRIC) reservation straddles the Phoenix and Pinal AMAs, occupying lands on both sides of the Gila River south of Phoenix, Tempe, and Chandler. It is inhabited by 14,000 people of the Pima and Maricopa tribes (ITCA, 2008), with approximately 11,300 inhabitants within the planning area. Industrial parks, gaming facilities and agriculture are the primary demand sectors. There are three industrial parks and a business park that occupy more than 800 acres of developable land. The agricultural industry brings more than $25 million of annual income to the GRIC in the form of 15,000 irrigated acres of GRIC farms and 22,000 independently farmed acres that produce cotton, wheat, millet, alfalfa, barley, melons, pistachios, olives, citrus and vegetables (ITCA, 2008). The Wild Horse Pass Casino and Vee Quiva collectively form the Gila River Casinos. The Sheraton Wild Horse Pass Resort and Spa includes a 17,500 square foot spa, two 18-hole golf courses, an equestrian center, and a 2½ mile long replica of the Gila River with scenic boat rides (NAU, 2008; ITCA, 2008). The GRIC was originally allocated 173,100 acre-feet/yr of CAP water for irrigation purposes in 1983. An additional 138,700 acre-feet/yr were allocated to the GRIC pursuant to the Arizona Water Settlement Act (Act) bringing their total CAP allocation to 311,800 acre-feet/yr (CAP, 2008). The Act and a subsequent settlement agreement specify the water rights assigned to the GRIC. The GRIC have rights to 13 categories of water including CAP, surface water, effluent and groundwater. In addition to CAP water, supplies include 125,000 acre-feet/yr of Globe Equity Decree Water (Gila River water) and 156,700 acre-feet of groundwater. In total, the GRIC are entitled to an estimated average of 653,500 acre-feet/yr for any period of ten consecutive years. In 2004, the GRIC pumped or received about 217,000 acre-feet of water. Ninety-eight percent of the demand was for agriculture. (ADWR, 2006b) The Community is in the planning stages of a large irrigation project with plans to establish an irrigation system to deliver water to 146,300 acres of land in seven reservation districts (GRIC, 2008). While up to 41,000 acre-feet/yr of Indian priority CAP water has been approved for lease to Phoenix AMA cities by the Tribal Council, no leases have been executed. Pascua Yaqui Tribe The Pascua Yaqui Tribe is composed of nine communities located in the Tucson, Phoenix and Pinal AMAs. The largest in terms of population is New Pascua, consisting of 1,152 acres of trust land located about 15 miles southwest of Tucson. New Pascua is recognized as the Pascua Yaqui reservation. The second largest community is Guadalupe located in the Town of Guadalupe southeast of Phoenix. Other communities in the Tucson AMA are: Old Pascua near downtown Tucson; Barrio Libre in the Town of South Tucson and Yoem Pueblo in Marana. Other communities in the 54 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 Phoenix AMA are Penjamo in Scottsdale and High Town in Chandler. Pinal AMA communities are located at Coolidge and Eloy (Pascua Yaqui Tribe, 2005). There are 3,315 members of the Pascua Yaqui tribe at New Pascua (2000 Census), but many tribal members live off the reservation in other communities in the planning area and also outside of Arizona. According to the Pascua Yaqui Tribe, in July 2005 there were almost 7,700 tribal members in the nine communities with a total Arizona population of approximately 13,100 (Pascua Yaqui Tribe, 2005). There is no irrigated acreage on the Pascua Yaqui Tribe reservation and the land dedicated to development of an industrial park currently remains vacant (NAU, 2008). There are two gaming facilities on the reservation and the 4,400 seat Anselmo Valencia Tori Amphitheater is southern Arizona’s largest concert venue. The Pascua Yaqui tribe holds a CAP allocation for tribal homeland uses of 500 acre-feet/yr (CAP, 2008). Salt River Pima-Maricopa Indian Community The Salt River Pima-Maricopa Indian Community (SRPMIC) is located entirely within the Phoenix AMA adjacent to the cities of Scottsdale, Fountain Hills, Mesa, Tempe and Phoenix. The lands within the 56,000-acre reservation have been allocated for different uses including agriculture, industrial and commercial use with the remaining acres reserved for recreation, housing and desert preservation (NAU, 2008). There are more than 6,200 members on the reservation representing the Pima and Maricopa tribes (2000 Census). There are 13,000 acres of irrigated lands with the primary crops being cotton, melons, potatoes, onions and carrots. Commercial land use is largely restricted to lands that bound Pima Road and the primary commercial use is a 140-acre retail center, “The Pavilions”. Other industrial uses include Cypress Golf Course (two nine-hole courses), Talking Stick Golf Club (a 36-hole course), a sand and gravel operation and a 200-acre landfill. There are two gaming facilities on the reservation, the Casino Arizona at McKellips and the Casino Arizona at Talking Stick. The SRPMIC holds a CAP allocation for irrigation use of 13,300 acre-feet/yr (CAP, 2008). The SRPMIC has executed long-term leases of CAP water to the cities of Gilbert (4,088 acre-feet/yr), Chandler (2,586 acre-feet/yr), Glendale (1,814 acre-feet/yr), Mesa (1,669 acre-feet/yr), Scottsdale (60 acre-feet/yr) and Tempe (60 acre-feet/yr). Tohono O’odham Nation The 2.8 million acre Tohono O’odham Nation is comprised of four separate reservations. The largest reservation, Tohono O’odham, is located within both the Pinal and Tucson AMAs and tribal lands extend south into Mexico. The Gila Bend Reservation (San Lucy District) is outside of the planning area in the Gila Bend Basin. The 71,095-acre San Xavier Reservation is located south of Tucson within the Tucson AMA. The smallest reservation is the 20-acre Florence Village located 2 miles west of Florence in the Pinal AMA. There are almost 24,000 members of the Nation with just over 5,000 members within the planning area. Industrial uses within the Nation include a 120-acre industrial park located within the San Xavier District of the Tohono O’odham Reservation. The Nation operates two casinos in the planning area, both located south of Tucson; the Desert Diamond I-19 Casino and the Desert Diamond Casino. The entire Tohono O’odham Nation holds a 74,000 acre-foot CAP allocation. The Southern Arizona Water Rights Settlement Act (SAWRSA) of 2004 (Title III of the Arizona Water Settlements Act) and the subsequent settlement agreement specified that the Nation was entitled to 79,200 Section 8.0 Overview DRAFT 55 Arizona Water Atlas Volume 8 acre-feet of water rights within the Tucson AMA for use on the San Xavier Reservation and the Eastern Schuk Toak District. Of this total, 66,000 acre-feet is CAP water and 13,200 acre-feet is groundwater. Both San Xavier and Schuk Toak have recently started large-scale irrigation projects. In 2005, more than 13,300 acre-feet of CAP water was used primarily for agricultural irrigation on these lands. (ADWR, 2006c) The Nation may lease up to 15,000 acre-feet of CAP water to off-reservation users. Yavapai-Prescott Indian Tribe The Yavapai-Prescott Indian Tribe reservation is approximately 1,400 acres located within the City of Prescott in the Prescott AMA. The reservation has approximately 180 members (2000 Census) of the Yavapai-Prescott Indian Tribe. Historical land uses included timber, mining and ranching, however, current tribal uses are business oriented. The tribe operates the 12-acre Sundog Industrial Park and the 250-acre Frontier Village shopping center. There are two gaming facilities on the reservation; the Yavapai Bingo and Gaming Center and Bucky’s Casino with the adjacent 160-room Prescott Resort and Conference Center (ITCA, 2008; NAU, 2008). The Yavapai-Prescott Tribe received an original allocation of 500 acre-feet of CAP water that was relinquished in 1994 by the tribe pursuant to its water rights settlement and acquired by the City of Scottdale in 1996 (CAP, 2008). Currently, the tribe is provided water by the City of Prescott, although they retained up to 1,000 acre-feet of annual surface water rights from Granite Creek. Municipal Demand Municipal, non-Indian demand is summarized by AMA and water supply in Table 8.0-10. Average annual demand during the 2001-2003 time period was almost 1.25 maf. Throughout the planning area, approximately 39% of the municipal demand is met with groundwater, 31% with surface water, 27% with CAP water and 3% with effluent (see Table 8.0-10). However, different supplies are utilized to meet municipal demand among the AMAs. The Phoenix AMA is unique in that it meets over 68% of its municipal demand with surface water from the CAP and the Salt and Verde river systems. Groundwater is the primary municipal water supply in the Pinal and Tucson AMAs. The Tucson AMA uses effluent to meet 6% of its municipal demand, the largest percentage of any AMA.

All of the water supplies in the Santa Cruz AMA are considered groundwater. A total of 52 water providers within the planning area each served more than 1,000 acre-feet of water, excluding effluent, in 2003 (see Table 8.0-11). Of these largest water providers, 33 are located in the Phoenix AMA and met 85% of the Phoenix AMA potable municipal demand. The 11 largest water providers in the Tucson AMA met 93% of the AMA’s potable municipal demand. In the other AMAs, the largest water providers met between 72% and 76% of the AMA’s potable municipal demand in 2003. Water providers fall primarily into two categories: public water systems or private water companies. Private water companies are regulated by the Arizona Corporation Commission (ACC), which oversees setting water rates in these service areas. Publically owned systems are not regulated by the ACC and have the authority to enact water conservation ordinances and establish water rates as approved by the appropriate governing body. This authority may provide greater flexibility to manage water resources within their water service areas. There are regulatory requirements for water providers within AMAs. Under the conservation programs in the AMA Management Plans, ADWR regulates water providers that annually serve more than 250 acre-feet of water for non-irrigation use as large municipal water providers. The Groundwater Code expressly mandates that these conservation programs require reasonable reductions in per capita water use through time and implementation of conservation measures designed to reduce water use within the service area. The Code also requires that reasonable conservation requirements be established for small municipal water providers. Golf Course Demand Golf courses within the planning area used approximately 125,000 acre-feet of water in 2006 (See Table 8.0-12). Each AMA within the planning area has golf course demand; however, there are significant differences in the number of golf courses within each AMA and the sources of water used to supply them. Pursuant to the Groundwater Code, water provided directly to a golf course by a water provider is categorized as municipal use and is calculated as part of the overall municipal demand. Groundwater that is withdrawn by the facility itself, through its own wells, is categorized as industrial use. Data from both municipal and industrial golf courses are shown in Table 8.0-12. Additionally, some golf courses receive effluent, surface water and CAP, either through direct delivery or via recovery of stored water, and these volumes may or may not be calculated within a water provider’s deliveries. Other unique situations also exist. For example, in the Santa Cruz AMA, the Palo Duro Golf Course receives water from municipal wells but it also receives remediated poor-quality water from the United Musical Instruments RCRA remediation site.

Mesa. Its eight canals deliver Salt and Verde river water, supplemented by groundwater, to municipal and agricultural users. It also wheels other kinds of water, including CAP water, through its system. In addition to providing untreated water for urban irrigation, the system is connected to eight municipal water treatment plants for delivery of potable water through municipal water systems. The largest water provider in the Phoenix AMA is the City of Phoenix which delivered 329,711 acre-feet of water in 2003. Its service area covers more than 500 square miles and serves a population in excess of 1.3 million (2000 Census). The City of Phoenix water system also provides water to a portion of the Town of Paradise Valley. The water system for the City includes four primary sources of supply with their associated percentages of use: surface water from the Salt and Verde river systems provided to the City by the SRP (54%); CAP water (36%); groundwater (3%); and effluent (7%) from three treatment facilities. The total potable system capacity is currently more than 780,000 acre-feet with a planned expansion to 1.2 maf. Major system components include five surface water treatment plants (Verde River plant, 24th Street, Deer Valley, Valley Vista and Union Hills); the Granite Reef Diversion Dam interconnect facility; a groundwater well system that includes 30 active wells; and more than 6,000 miles of water mains (City of Phoenix, 2005). Section 8.0 Overview DRAFT 59 Arizona Water Atlas Volume 8 The City utilizes reclaimed water from the Cave Creek Water Reclamation Plant to irrigate turf in northeast Phoenix and provides reclaimed water from the 91st Avenue WWTP, through the Tres Rios Wetlands Project, to the Buckeye Irrigation Company and the Palo Verde Nuclear Generating Station for cooling purposes. The City also provides reclaimed water from the 23rd Avenue WWTP to the Roosevelt Irrigation District for agricultural irrigation. The volume of reclaimed water available exceeds demand and the City is developing ways to fully utilize this water source. (City of Phoenix, 2005) The Cities of Mesa, Scottsdale, Tempe and Chandler, all located in the East Salt River Valley, each served over 50,000 acre-feet of water in 2003 (see Table 8.0-11). The City of Mesa is the second largest provider in the AMA; serving over 100,000 acre-feet of water in 2003. The western part of the Mesa service area is within the SRP and RWCD boundaries and receives Salt and Verde river water. Approximately half of Mesa’s demand is supplied by the SRP and 11% by RWCD. Mesa utilizes a variety of other water supplies including groundwater, CAP water, other Colorado River water, SRPMIC lease water and effluent (City of Mesa, 2004). The City of Scottsdale delivered almost 78,000 acre-feet of water in 2003. About 48% of the City’s demand is met with CAP water and 47% by groundwater. Less than 5% of its water supply is SRP surface water. Scottsdale operates the Scottsdale Water Campus that treats wastewater and CAP water. Wastewater is treated to irrigation standards for use at golf courses, and when irrigation needs are reduced in the winter, the wastewater is treated to drinking water standards and recharged to the aquifer via injection wells. (City of Scottsdale, 2007 and ADEQ, 2008) The City of Tempe delivered approximately 57,700 acre-feet of water to customers in 2003. Most of its water supply is surface water from the SRP. Groundwater provides from 1% to 7% of the total supply depending on surface water availability. In 2005, about 7% of Tempe’s water demand was met by groundwater. (City of Tempe, 2006) The City of Chandler is the fifth largest water provider in the Phoenix AMA; delivering over 57,000 acre-feet of water in 2003. Water supplies include SRP water, Salt and Verde river water, CAP water, Colorado River water, groundwater and effluent (City of Chandler, 2002). Pinal AMA For the 2001-2003 time period, the average annual municipal demand in the Pinal AMA, excluding Indian demand, was 26,800 acre-feet. Average annual municipal demand has increased almost 20% over the last decade, spurred by a population that grew by 65% from 2000-2006. However, municipal demand is still a relatively small percentage of non-Indian demand within the AMA, accounting for only 3% of the demand. There are four population centers within the Pinal AMA, Casa Grande, Coolidge, Eloy, and Florence, with the fastest population growth occurring in the Casa Grande area where more than 70% of the municipal demand is located. Almost 85% of the municipal demand is met with groundwater, although the four water providers serving these population centers hold CAP allocations sufficient to meet almost 50% of the 2006 municipal demand. The lack of water treatment facilities to treat CAP water for potable use is currently a limiting factor to utilize this supply (City of Casa Grande, 2001). The largest water provider in the Pinal AMA is a private water company, Arizona Water Company - Casa Grande System (AWCCG), that supplied 13,540 acre-feet of water to Casa Grande and the surrounding area in 2003. The service area for the AWCCG is about 140 square miles with a distribution system consisting of approximately 466 miles of pipes. The primary source of supply used by the AWCCG is groundwater withdrawn from 15 active wells. The AWCCG also provides 60 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 untreated CAP water to two private golf courses and an electric power plant within its service area. In addition, the City of Casa Grande WWTP delivers effluent to the power plant and the City’s municipal golf course. The treatment plant produces approximately 2,900 acre-feet of effluent per year. Prescott AMA For the 2001-2003 time period, the average annual municipal demand in the Prescott AMA was 17,300 acre-feet. This includes Indian demand as the Yavapai-Prescott Indian Tribe currently receives potable water from the City of Prescott. The Prescott AMA continues to experience an increase in municipal water use and a decrease in agricultural demand. Municipal demand accounts for almost 70% of water use within the AMA and that demand is met primarily with groundwater. The “tri-cities” of Prescott, Prescott Valley and Chino Valley are the population centers of the Prescott AMA, with Prescott and Prescott Valley accounting for nearly 80% of the municipal deliveries. The largest water provider in the Prescott AMA is the City of Prescott, which supplied over 6,900 acre-feet of groundwater in 2003 to a service area that covers approximately 50 square miles. Although groundwater is the primary source of water used to meet municipal demand, the City also holds surface water rights, including recently purchased rights to surface water stored in Watson and Willow Lakes. Due to the lack of a surface water treatment facility, any use of surface water is done through underground recharge and recovery. During the 2001-2003 time period the City of Prescott recovered 570 acre-feet of surface water recharge credits, delivered approximately 1,400 acre feet of effluent to turf facilities and recovered approximately 130 acre-feet of effluent recharge credits for municipal use. The second largest water provider in the Prescott AMA is the Town of Prescott Valley that supplied almost 5,000 acre-feet of groundwater in 2003. In 2003, the Town also recharged more than 1,700 acre-feet of effluent and directly delivered over 300 acre-feet of effluent for golf course use. The Town of Chino Valley and the newly incorporated town of Dewey-Humboldt meet most of their municipal demand through small private domestic (exempt) wells. Santa Cruz AMA For the 2001-2003 time period, the average annual municipal demand in the Santa Cruz AMA was 8,300 acre feet. There is no Indian demand within this AMA. Like the other AMAs, the Santa Cruz AMA is experiencing an increase in municipal demand; however, this is still secondary to agricultural demand. Municipal demand accounted for almost 35% of the total demand with the two primary demand centers served by the City of Nogales and Rio Rico Utilities. The service areas of these two providers have shown a 5-8% annual increase in population over the last decade. The City of Nogales is the largest water provider and served more than 4,200 acre-feet to its customers in 2003. Its service area is located along the international border both east and west of Interstate 19, encompasses approximately 20 square miles, and includes areas both inside and outside the city limits. The City currently has a Designation of AWS, with an aggregate volume of 6,322 acre-feet per year in normal years, and 5,473 acre-feet per year in a drought year. Total pumpage by the City has fluctuated, with a slight increase during the period 1996-2006 (Figure 8.0-17). Fluctuations may be related to a number of factors including: the number of border Section 8.0 Overview DRAFT 61 Arizona Water Atlas Volume 8 Figure 8.0-17 City of Nogales, Arizona water use 1996-2006 5000 50,000 4000 45,000 Water Use (acre-feet) 3500 3000 40,000 2500 2000 35,000 1500 1000 30,000 Nogales Border Crossings (people per day, entering US) 4500 Pumpage Non-Residential 500 0 1996 Residential Border Crossings 1997 1998 1999 2000 2001 2002 2003 2004 2005 25,000 2006 Year crossings, weather conditions, distribution system problems, and record-keeping changes. The City currently operates 14 wells, and relies on a combination of surface water and groundwater withdrawn from wells near the Santa Cruz River, as well as water withdrawn from the Potrero groundwater basin. One well near Coronado Canyon in the Potrero basin accounts for over onethird of the City’s total pumpage. Municipal water uses consist of residential demand, produce storage and processing, tourist service industry use, and light manufacturing. Two turf-related facilities, Palo Duro and Kino Springs golf courses, use water supplied by the City of Nogales. Residential demand has slightly decreased, while non-residential demand has increased since 1996. Nogales has a relatively high GPCD rate due in part to the greater proportion of non-residential water demand (approximately 1:1 with residential use). Part of this non-residential demand is due to water uses associated with the large number of people who cross the border from Nogales, Sonora into Nogales, Arizona each day. Annual non-residential demand trends closely track the number of border crossings reported by US Customs and Border Patrol; in particular, a reduction in crossings due to increased border security measures implemented in 2001 corresponds to a steep drop in demand. Overall, the number of border crossings into Arizona at the Nogales ports of entry rose 21% from 1996-2006 (see Figure 8.0-17). Tucson AMA For the 2001-2003 time period, the total annual municipal demand in the Tucson AMA was 181,980 acre-feet, excluding Indian demand. Municipal demand accounts for almost 56% of the total non-Indian demand and almost 78% of that demand was met with groundwater supplies during 2001-2003. In general, surface water sources are limited within the Tucson AMA and 62 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 CAP water is the most abundant renewable supply available. The City of Tucson, one of the four population centers of the AMA, accounts for approximately 68% of the municipal demand. The other population centers are Marana, Oro Valley and the Sahuarita/Green Valley area. The City of Tucson municipal water utility, Tucson Water, has the highest municipal demand of any large water provider in the Tucson AMA. In 2003 it served over 123,000 acre-feet of water to its customers within a service area approximately 300 square miles in size. The City’s system includes both a potable and non-potable (reclaimed) system. (City of Tucson, 2004) Until the 1990s, Tucson Water relied solely on groundwater and a relatively small volume of effluent for its supply, although it currently has a CAP allotment of 144,000 acre-feet. In 1992, Tucson Water began direct delivery of CAP water to residential customers. Those deliveries were discontinued in 1994 due to aesthetic issues and delivery problems. In 1995, a voter approved initiative restricted Tucson Water from delivering treated CAP water directly. In response to this initiative, Tucson Water chose to recharge the CAP water and then deliver the recovered water to residential customers. In 1996, Tucson Water began operation of the 80,000 acre-foot Central Avra Valley Storage and Recovery Project (CAVSRP). In 2008, a second recharge facility, the 60,000 acre-foot Southern Avra Valley Storage and Recovery Project (SAVSRP), was completed (see Figure 8.5-9). A series of recovery wells has been constructed in conjunction with each of these recharge sites with the anticipation that Tucson Water will eventually be able to store and recover its entire CAP allocation. Tucson Water also relies on effluent to meet demand and offset the use of groundwater. In 2000, reclaimed water use accounted for 8% of Tucson Water’s total demand. (City of Tucson Water Department, 2004) Average annual effluent demand was approximetly 11,600 acre-feet during the 2001-2003 time period. Golf courses in the City of Tucson and Oro Valley consume approximately 66% of the reclaimed water. The rest is served to parks, schools and individual home owners. In addition to direct delivery of reclaimed water deliveries through the non-potable system, the City of Tucson recharges a portion of its effluent. (City of Tucson Water Department, 2007) In addition to Tucson Water, eleven water providers serve over 1,000 acre-feet of water annually in the Tucson AMA. In the northwest area of the Tucson AMA the largest providers are the Town of Oro Valley, which served approximately 10,233 acre-feet in 2003, and Metropolitan Domestic Water Improvement District (Metro Water), which served 9,002 acre-feet in the same year. Green Valley Water Company and the Community Water Company of Green Valley served a combined total of 5,022 acre-feet to their customers in 2003. A number of large providers in the Tucson AMA have a CAP allocation; however, many do not have physical access to the supply and currently none are serving it directly (see Appendix B). A growing number of providers are using their allocations through annual storage and recovery. Agricultural Demand The planning area includes AMAs where agriculture is the predominant demand sector and AMAs with little agricultural use, although agricultural demand exists in every AMA. Total annual average non-Indian agricultural demand for the 2001-2003 time period was in excess of 1.8 maf Section 8.0 Overview DRAFT 63 Arizona Water Atlas Volume 8 (see Table 8.0-13). Agricultural demand is the greatest in the Phoenix and Pinal AMAs where it accounts for almost 42% and 95% respectively, of the total non-Indian demand. Table 8.0-13 Agricultural demand in the AMA Planning Area excluding Indian demand Phoenix AMA Groundwater Surface Water CAP Effluent Other Total Pinal AMA Groundwater Surface Water CAP Effluent Total Prescott AMA Groundwater Surface Water Effluent Total Santa Cruz AMA Groundwater Total Tucson AMA Groundwater CAP Effluent Total Total All Basins 1991-1995 (acre-feet) 1996-2000 (acre-feet) 2001-2003 (acre-feet) 453,800 453,100 119,000 30,000 2,000 1,057,900 431,700 262,000 292,200 59,700 2,000 1,047,600 388,100 168,900 266,100 65,000 2,100 890,200 297,600 162,600 269,600 2,800 732,600 397,100 99,900 373,800 1,500 872,300 383,800 52,100 409,700 1,600 847,200 5,600 9,500 900 16,000 5,400 3,100 1,400 9,900 4,000 600 1,500 6,100 11,400 11,400 13,500 13,500 14,000 14,000 85,000 3,000 2,600 90,600 1,908,500 82,300 23,400 1,400 107,100 2,050,400 76,600 16,800 0 93,400 1,850,900 Notes: Within the Santa Cruz AMA water is not separately defined as surface water or groundwater, therefore all volumes are reported as groundwater. Agricultural water use within AMAs is subject to Groundwater Code regulations that limit use of groundwater for irrigation purposes in several ways. Within AMAs there is a prohibition on new irrigated lands and management plan conservation requirements set maximum annual groundwater allotments. The maximum annual groundwater allotment for an irrigation right is determined by multiplying the irrigation water duty by the water duty acres in the farm. The irrigation water duty is the annual amount of water (in acre-feet per acre) that is reasonable to apply to land to produce the crops historically grown (1975 to 1980) divided by an assigned irrigation efficiency. To be in compliance with management plans, irrigation efficiency must improve through time. Under the management plans, agricultural water users may participate in alternative conservation programs such as the historic cropping program or a best management practices (BMP) program. All agricultural conservation programs are required to conserve equivalent volumes of water. 64 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 Due to the AMA regulations that restrict new irrigated acres and require improved efficiencies, agricultural demand should not significantly increase within the AMAs as may occur in non-AMA planning areas. Additionally, as the AMA population centers grow, urbanization should result in a decrease in agricultural demand over time. This is evident in the Phoenix AMA where over 130,000 acres of agricultural land have been urbanized since 1984. The AMA Planning Area includes two of the largest agricultural areas in Arizona, Pinal and Maricopa Counties, located in the Pinal and Phoenix AMAs, respectively. Only Yuma County is larger statewide in terms of production and water use. Crops grown in Maricopa County include (in order of harvested acres for 2003) alfalfa hay, upland cotton, wheat, principal vegetables (includes lettuce, broccoli, cauliflower, onion, and melons), barley, citrus, other hay and corn for grain. Annual agricultural sales are reported to total over $740 million. In Pinal County, the crops grown include (in order of harvested acres for 2003) upland cotton, alfalfa hay, durum wheat, barley, corn for grain, other hay, and Pima cotton. Annual agricultural sales are reported to total over $424 million (NASS, 2008). There are 39 irrigation districts within the planning area located as follows: Phoenix AMA (33); Pinal AMA (4); Prescott AMA (1); Santa Cruz AMA (0); and Tucson AMA (1). Figure 8.0-18 shows the general location of the largest irrigation districts within the planning area. Figure 8.0-18 Large irrigation districts in the AMA Planning Area Section 8.0 Overview DRAFT 65 Arizona Water Atlas Volume 8 The source of water used for irrigation differs widely throughout the planning area. Due to regulations on agricultural water users within the AMAs, some irrigation Effluent districts utilize a number of different water 4% sources to ensure that they remain in compliance with conservation requirements. Overall, the sources of water available are groundwater, in lieu water, CAP water, effluent, surface water, and tailwater. In lieu water is a renewable water supply, typically CAP water, that is delivered by a water CAP Groundwater storer to a groundwater savings facility 37% (GSF), typically a farm or irrigation district, 47% pursuant to permits issued under A.R.S. § 45-812.01. The in lieu water is used in an AMA or an irrigation non-expansion area (INA) by the recipient (agricultural water user) on a gallon-for-gallon substitute basis for groundwater that otherwise would have been pumped from within that AMA or Surface Water INA. In lieu water is included as CAP water demand in the Atlas. Water supplies used by 12% the agricultural sector are shown in Figure 8.0-19. Approximately 47% of the agricultural demand is met by groundwater, 37% by CAP water, 12% by surface water and 4% by effluent. Figure 8.0-19 Average agricultural water use in the AMA Planning Area 2001-2003 Water that runs off the end of the field after an irrigation event is called tailwater and is used most frequently in the Phoenix AMA. Irrigators benefit by capturing and reusing this runoff because while the first application of water is counted within the allotment given to agricultural rightholders, if tailwater can be collected and re-used in any way, the second (and subsequent) applications of water do not count against an allotment. Use of tailwater is a component of the Agricultural BMP conservation program previously discussed. Phoenix AMA Average non-Indian agricultural demand in the Phoenix AMA for the 2001-2003 time period was just over 890,000 acre-feet per year, or 40% of the total agricultural demand in the planning area. Agricultural water demand has shown a decreasing trend over the last decade. The majority (approximately 80%) of agricultural demand is associated with seven of the largest irrigation districts: Salt River Project, Roosevelt Irrigation District (RID), Roosevelt Water Conservation District (RWCD), Buckeye Water Conservation and Drainage District (Buckeye), New Magma Irrigation and Drainage District (NMIDD), Maricopa Water District and Queen Creek Irrigation District. Most of the irrigated lands are located in the central and south-central portions of the AMA (see Figure 8.1-12). Water supplies to meet agricultural demand include groundwater, in lieu water, CAP water, surface water, effluent and tailwater. All seven of the largest irrigation districts utilize at least three different sources of supply. The largest irrigation district within the Phoenix AMA is the SRP. 66 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 Analysis of agricultural water demand trends of five irrigation districts in the Phoenix AMA shows an overall decrease in water use of approximately 11,500 acre-feet per year between 1984 and 2002. There have been spatial variations in this decrease due to the proximity of agricultural lands to urban areas and the availability and cost of water supplies. Agricultural lands in the SRP service area decreased by more than 50% from 1984 to 2002 with an associated reduction in demand of approximately 9,800 acre-feet/year. RWCD, also located near the Phoenix metropolitan area, experienced similar declines, though not as pronounced as SRP. Demand within the RID, located on the western edge of the Phoenix metropolitan area, has been stable, likely due to increased utilization of effluent and changes in crop type. Buckeye, located south of and adjacent to RID is in a waterlogged area, requiring pumping of excess water. Water demand has increased within RID, likely due to increased farming to offset reductions in production in other parts of the AMA. Similarly, demand increased within the NMIDD, located in the southeastern part of the AMA. The increase is likely related to the availability of Colorado River water and, like RID, increased farming to offset reductions in production due to urbanization. (Hetrick and Roberts, 2004) Pinal AMA Non-Indian agricultural demand in the Pinal AMA for the 2001-2003 time period averaged approximately 847,000 acre-feet per year, or 46% of the total agricultural demand in the planning area. Agricultural water demand has remained relatively constant in the Pinal AMA with a 15-year average water use of approximately 778,000 acre-feet per year. However, there has been a significant shift in the source of supply within the Pinal AMA (see Table 8.2-10). Prior to the availability of CAP water in the AMA (approximately 1987) almost all agricultural demand was met with groundwater or surface water supplies from the Gila River. Today, approximately 410,000 acre-feet of CAP water is used to meet demand. The majority (approximately 87%) of agricultural demand in the AMA is associated with four large irrigation districts: Central Arizona Irrigation and Drainage District (CAIDD), MaricopaStanfield Irrigation and Drainage District (MSIDD), Hohokam Irrigation and Drainage District (HIDD), and San Carlos Irrigation and Drainage District (SCIDD). Most irrigated lands are located in the northern half of the AMA (see Figure 8.2-12). Groundwater is pumped to supplement CAP deliveries in CAIDD, MSIDD and HIDD and surface water in SCIDD, up to the total amount of water allotted annually to the farms in each district. SCIDD receives and distributes surface water from the Gila River pursuant to the Globe-Equity Decree6. The largest irrigation district within the Pinal AMA is MSIDD. The MSIDD was organized in 1962 to obtain supplemental water from the CAP and construction of all CAP facilities in the district was completed in 1989. The district operates the Santa Rosa Canal, 78 miles of main conveyance canals, 116 miles of lateral canals and pipelines and 484 irrigation wells. MSIDD does not own the individual irrigation wells but leases them from the landowners; only 80 are directly connected to MSIDD’s distribution system. The district boundaries encompass approximately 148,000 acres and 89,000 acres have a recent history of irrigation. 6 In 1935 the U.S. District Court entered a consent decree (Globe Equity No. 59) for all diversions of the mainstem of the Gila River from its confluence with the Salt River to the headwaters in New Mexico, including the Gila River and San Carlos Apache reservation and non-Indian landowners below and above Coolidge Dam. Section 8.0 Overview DRAFT 67 Arizona Water Atlas Volume 8 Prescott AMA Average annual agricultural demand in the Prescott AMA for the 2001-2003 time period was 6,100 acre-feet, or less than 1% of the total agricultural demand in the planning area. There has been a significant decrease (approximately 60%) in agricultural use within the AMA over the past two decades. Agricultural demand is now approximately 24% of the total Prescott AMA demand. Historically, both groundwater and surface water supplies were utilized to meet agricultural demand; however, there has been a shift to greater utilization of groundwater and recovery of effluent credits due to transfer of Chino Valley Irrigation District (CVID) surface water rights to the City of Prescott. Most of the irrigated lands are located in the northern part of the AMA near the Town of Chino Valley (approximately 1,800 acres) where groundwater and recovered effluent are used. An additional 476 acres are currently irrigated with groundwater in the southern portion of the AMA along the Agua Fria River (see Figure 8.3-12). The only irrigation district within the Prescott AMA is CVID, located in the Little Chino Sub-basin. CVID originated at around the turn of the 20th century as the Arizona Land and Irrigation Company and was incorporated as CVID in 1926. Historically, the CVID was entirely a surface water provider that supplied water to slightly more than 2,500 acres of irrigated lands (Gookin, 1977). Surface water was diverted from two reservoirs, Watson Lake and Willow Lake that are connected by a cross-cut canal constructed in 1965. In 1998, CVID entered into an intergovernmental agreement (IGA) with the City of Prescott in which CVID’s surface water rights were relinquished to the City. Pursuant to the IGA, all CVID deliveries from Prescott are now effluent through recovery of long-term storage credits; however, CVID retained a small commitment to serve surface water to three CVID properties (< 30 acre-feet). The maximum annual recovery limit under the IGA is 1,500 acre-feet until a total of 33,000 acre-feet have been recovered. As of 2007, CVID consisted of approximately 480 irrigated acres and had ceased delivery of surface water. Santa Cruz AMA Agricultural demand in the Santa Cruz AMA for the 2001-2003 time period averaged 14,000 acrefeet per year, or less than 1% of the total agricultural demand in the planning area. Agricultural demand has remained relatively stable in the AMA, which has no organized irrigation districts. The predominant agricultural use is pasture land and one irrigation right holder accounts for 33-50% of all agricultural use in the AMA. Tucson AMA Non-Indian agricultural demand in the Tucson AMA for the 2001-2003 time period averaged 93,400 acre-feet per year, or approximately 5% of the total agricultural demand in the AMA Planning Area. Agricultural demand has remained relatively constant and accounts for approximately 28% of the Tucson AMA water demand. Groundwater is the primary agricultural water supply. During 2001-2003, in lieu CAP water was also used, which met about 18% of the agricultural demand. There are two primary agricultural centers: Avra Valley near the town of Marana, and the Green Valley area along the Santa Cruz River (see Figure 8.5-12). The only agricultural irrigation district in the AMA with a consolidated distribution system is the Cortaro-Marana Irrigation District (CMID). Located in the Avra Valley/Marana area, the District 68 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 is an arm of the Cortaro Water Users’ Association, which was formed in 1948. CMID pumps water from wells to serve its customers. It has several surface water rights and claims wells as points of diversion; however, the Department accounts for this water as groundwater in its water budget. The District operates a delivery system that provides water to about 11,000 irrigated acres. The system consists of almost 54 miles of concrete lined canals, eight miles of pipeline and 45 irrigation wells. In 2003, CMID delivered approximately 40,000 acre-feet of water to its customers. Approximately 2,000 acre-feet of this water was in lieu CAP. Other farming operations in the Avra Valley include those within the Avra Valley Irrigation District (which does not operate a consolidated distribution system), BKW Farms, and other irrigators. Both groundwater and CAP water are used to irrigate crops, which are predominantly cotton in this area. In 2003 approximately 16,000 acre-feet of groundwater was used, along with approximately 6,900 acre-feet of in lieu CAP. A large agricultural operation, Farmers Investment Company (FICO), is located in the Sahuarita – Green Valley area and consists of predominantly pecans. FICO is separated into two operating areas: the northern section has approximately 4,000 acres and the southern section approximately 1,800 acres. FICO used approximately 28,400 acre-feet of groundwater in 2003. Although FICO is currently permitted to receive in lieu CAP, the physical infrastructure necessary to deliver CAP does not yet exist. Another relatively large farming operation is located in the northern part of the AMA near Red Rock. Kai Farms-Red Rock grows predominantly row crops and has recently planted pecans. In lieu CAP water and groundwater are used for irrigation. In 2003, 8,378 acre-feet of in lieu CAP was used to meet demand. Industrial Demand Industrial demand in the AMA Planning Area averaged just over 283,000 acre-feet annually between 2001and 2003, with 2003 demand slightly more than 250,000 acre-feet. Industrial demands accounted for 7.5% of the total water demand in the planning area during the 2001-2003 time period. While the composition of industrial demand differs among the AMAs, turf demand is the highest demand sector overall, followed by power plants and mining. Industrial demand is the greatest in the Phoenix AMA with 75% of the total industrial demand in the planning area. The Tucson AMA has the second largest volume of industrial demand in the planning area, accounting for 18% of the total. (See Table 8.0-14) Within the AMA Planning Area, industrial water use is specifically defined as water that is utilized pursuant to specific non-irrigation groundwater rights or permits. Water that is supplied by municipal providers for industrial or commercial use is not reflected within the industrial sector but is instead included within municipal demand. Based on this definition of industrial use, the predominant source of supply is groundwater; however, some CAP water and effluent is used to meet demands. All users classified as industrial users within the AMAs have general conservation requirements under the AMA management plans. Additional, specific conservation requirements exist for turfSection 8.0 Overview DRAFT 69 Arizona Water Atlas Volume 8 related facilities, power plants, sand and gravel facilities, dairies, feedlots, large cooling facilities, new large landscape users and new large industrial users. “Other industrial users” shown in Table 8.0-14 are subject to the general requirements that apply to all industrial users.

On average, industrial demand was approximately 213,600 acrefeet/yr during 2001-2003, or 10% of the Phoenix AMA non-Indian demand. The largest industrial use category in the AMA is turf related facilities, primarily golf courses, which accounted for 45% of the industrial use in 2003. Power plants, specifically the Palo Verde Nuclear Generating Facility, 70 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 are the second highest use at 35%. Palo Verde uses over 60,000 acre-feet per year, a majority of which is effluent. Although the total annual demand in the AMA has been increasing, the portion attributed to industrial use has remained fairly stable. Though dairy operations have been relocating from the Phoenix AMA to the Pinal AMA and rural Arizona, there are still 87 large-scale operations in the AMA representing 6% of the total industrial demand in 2003. Sand and gravel operations are a fairly stable demand within the Phoenix AMA with approximately 5% of the total industrial demand. Approximately 10% of the industrial demand is by “other” industrial users such as small-scale dairies, industrial facilities and high water use landscape areas less than ten acres in size. Pinal AMA Industrial demand in the Pinal AMA in 2003 was 14,900 acre-feet, or 6% of the total industrial demand in the planning area. On average, industrial demand was 14,000 acre-feet/yr during 2001-2003, or 2% of the Pinal AMA non-Indian demand. The largest industrial use category in the AMA is dairies and feedlots. Seventeen new, large-scale dairies were constructed in the Pinal AMA during the period from 2000 to 2006, bringing the total number to 28. Many of the new dairies relocated from the Phoenix AMA, as that area underwent urbanization. The number of new dairies in the AMA has leveled off, with only three dairies having started operation since January 2004. The Department is aware of only one dairy that is currently in the planning stage and likely to be constructed. In addition to the increased industrial demand associated with new dairies, the increase in the number and size of dairies has led to both a significant increase in the acreage of forage crops and conversion to forage crops in the AMA, impacting agricultural demand as well. Prescott AMA Industrial demand within the Prescott AMA is limited to two golf courses (Prescott Country Club and Quailwood), sand and gravel operations and other industrial uses. Groundwater is the only water supply used by the industrial sector. The 2003 demand was approximately 1,570 acre-feet, less than 1% of the total industrial demand in the planning area. On average, industrial demand was approximately 1,500 acre-feet/yr, or 6% of the Prescott AMA demand during 2001-2003. Santa Cruz AMA Approximately 6% of the average (2001-2003) total water demand in the Santa Cruz AMA is industrial. In 2003, industrial demand was 1,420 acre-feet, less than 1% of the total industrial demand in the planning area. Most industrial demand occurs at two industrial golf courses, other turf-related facilities, and sand and gravel operations. Tucson AMA Industrial demand in the Tucson AMA in 2003 was 46,600 acre-feet, or 18% of the total industrial demand in the planning area. On average, industrial demand was approximately 51,300 acre-feet during 2001-2003, accounting for 16% of the Tucson AMA demand. Industrial demand is met primarily with groundwater. The mining sector accounts for almost 70% of the industrial demand in the AMA. The majority of mining demand is from the metal mining industry, specifically copper. Water use in this industry Section 8.0 Overview DRAFT 71 Arizona Water Atlas Volume 8 has fluctuated through time, reaching a peak in the mid 1990s when almost 50,000 acre-feet of water was used. By 2002, water use fell by almost half due to low copper prices. More recently, with the price of copper at historic highs, mining water use numbers are on the rise. Historically, all mining water use has been supplied by groundwater. In addition to the metal mining industry, other industrial users in the Tucson AMA include sand and gravel facilities, turf facilities, electric power plants, a dairy and other types of industrial users. 8.0.8 Water Resource Issues in the AMA Planning Area A number of complex issues exist in the AMA Planning Area. Issues have been identified by the Department within management plans, through stakeholder processes, a Governor’s Commission, the Arizona Town Hall, and numerous community water resource groups. Groundwater pumping, achievement of management goals, access to renewable water supplies, statutory constraints, environmental protection, local area management and increasing salinity are some of the important considerations in the planning area. Discussed below are issues that have been identified in the past decade and are common to multiple AMAs. The Department is currently identifying AMA issues as it begins development of the fourth management plan and will more specifically evaluate them through that process. Residual (Allowable) Groundwater Pumping and Management Goals The amount of groundwater withdrawals allowed under the Groundwater Code, management plans and Assured Water Supply (AWS) Rules through groundwater rights, groundwater permits, and certificates and designations of AWS creates a significant obstacle towards achieving AMA management goals. Four of the five AMAs have a safe-yield component as part of their goal. Safeyield is defined as, “to achieve and thereafter maintain a long-term balance between the annual amount of groundwater withdrawn in an active management area and the annual amount of natural and artificial groundwater in an active management area.” A.R.S. § 45-561(12). Groundwater pumped in excess of safe-yield is termed groundwater “mining” or overdraft. The safe-yield AMAs (Phoenix, Prescott, Santa Cruz and Tucson) have made progress toward achieving their management goals through recharge, replenishment, retirement of agricultural pumpage and conservation although there are still challenges. As allowed by the Code, AWS Rules and the management plans, the responsibility to reduce mined groundwater pumping does not apply proportionately or equitably to all water-using sectors. For example, water providers designated as having an AWS are required to use renewable supplies, though they are authorized to continue to use a limited amount of groundwater. Although there are incentives in the management plans for industrial and agricultural users to use renewable water supplies, there are no mandatory restrictions. Access to sufficient non-groundwater sources by these water users is also a long-term obstacle to achieving safe-yield. In some AMAs the allowable pumping volume may be a large proportion of the overdraft. Pumpage by domestic/exempt wells is a water use that is neither subject to groundwater replenishment or management plan requirements. Exempt well pumpage represents a significant amount of water demand in some AMAs. For example, it is estimated that there are over 9,000 exempt wells in use in the Prescott AMA, which may account for as much as 25 percent of the 72 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 municipal water use. (Since exempt wells are exempt from the Department’s reporting requirement, the actual water use is unknown). With the ongoing practice of parcel splits not subject to the State’s subdivision laws, the number of exempt wells serving these parcels is expected to increase. Dry lot developments, where each lot owner drills their own well due to the lack of a centralized water service, may also increase. Access to Renewable Water Supplies Utilization of renewable supplies has increased over the past 20 years, facilitated by the construction of surface water treatment plants and completion of the CAP, allowing use of Colorado River water either directly or indirectly through artificial recharge and recovery projects. A number of issues have been identified associated with the use of CAP water. These issues include: limited CAP supplies; the need to construct new infrastructure to permit full utilization of supplies; financing of infrastructure; and the long term roles of the Central Arizona Groundwater Replenishment District (CAGRD) and the Arizona Water Banking Authority (AWBA) to ensure long-term availability of renewable supplies for AMAs. As groundwater supplies diminish and more development occurs that requires groundwater replenishment (e.g. the AWS Rules), there will be more competition for renewable water supplies to meet current and future demands. In addition to the current users, smaller water providers and other groundwater users may not have physical access to these supplies to offset their ongoing use of groundwater. The reallocation of CAP Non-Indian Agricultural water is an example of how much interest there is in renewable water supply acquisition, even for a relatively small volume of low priority, expensive water. A number of CAP Municipal and Industrial (M&I) subcontractors lack direct access to CAP water and must utilize the resource indirectly through underground storage facilities (USF), or groundwater savings facilities (GSF), located in proximity to the CAP infrastructure. Because the recovery is not required to occur in the area of replenishment, some areas may experience local water level declines and encounter physical availability limitations in the future. Funding for extension of the CAP canal in Tucson, as well as for treatment and other secondary infrastructure in all AMAs, is an issue to renewable supply utilization in some areas. The CAGRD is also competing for the same renewable water supplies as other users in the Phoenix, Tucson and Pinal AMAs in order to meet its replenishment obligations to its member lands and member service areas under the AWS program. Developers and water providers contract with the CAGRD to replenish groundwater withdrawals as required by the AWS Rules. If the CAGRD cannot meet its obligations, its plan of operation will be considered inconsistent with the AMA management goal, which could impact approval of AWS Certificates and jeopardize the status of AWS Designations. There are also concerns regarding the spatial disconnect between CAGRD storage sites and recovery sites. AMAs without access to CAP water must look to other water supplies to meet their management goals. For the Prescott AMA transporting alternative long-term supplies into the AMA is critical to achieving safe-yield in this groundwater-dependent AMA. The only alternative supplies currently available are a limited amount of effluent and transportation of groundwater from the adjacent Big Chino Sub-basin pursuant to A.R.S. § 45-555. In the Santa Cruz AMA access to both renewable Section 8.0 Overview DRAFT 73 Arizona Water Atlas Volume 8 and groundwater supplies are influenced by water demand in the large upstream community of Nogales, Sonora. Some of this demand is offset by delivery and treatment of effluent generated in Mexico at the Nogales, Arizona, International Wastewater Treatment Plant (IWWTP), which discharges treated effluent to the Santa Cruz River near Rio Rico. However, there are currently no treaties or legal agreements regarding rights to the treated effluent nor for continued delivery and treatment of Mexican effluent at the IWWTP. Effluent is a growing renewable resource in all AMAs, but physical distance between the location where the effluent is generated and the location of potential users, and lack of delivery infrastructure, limit its direct use in some areas. As with CAP water, recharge and recovery is utilized with similar concerns about the spatial disconnect between storage and pumping. Statutory differences between groundwater and non-groundwater sources and conjunctive use Groundwater and surface water are managed under different statutes with limited integration and consistency in approach. In the rapidly growing AMAs with multiple water sources, the statutory ability to manage only groundwater may be problematic. If any groundwater is part of the supply, the entire supply can be managed as groundwater, but there are many instances where non-groundwater supplies are exclusively used. Water management efforts are currently fragmented because effluent, CAP water, surface water and groundwater are all regulated differently and owned and controlled by different entities. This fragmentation exacerbates other issues, particularly those associated with ownership of water supplies. An exception is the Santa Cruz AMA, where the legislation that created the AMA expressly addressed its unique hydrogeology and the inter-connection of surface and groundwater supplies. It is necessary to coordinate management of these supplies to meet the Santa Cruz AMA management goal due to the highly seasonal and drought-sensitive conditions along the Santa Cruz River. Environmental Protection Few perennial riparian habitats remain in the AMA Planning Area; restoration and preservation of these areas have become a high priority in some AMAs. Issues center on the effects on these areas by continued groundwater pumping and surface water diversions. These riparian areas function as natural recharge zones through streambed infiltration and can beneficially serve both environmental and water management objectives if managed appropriately. Critical Area Management There is a growing consensus throughout the AMA Planning Area that a mechanism is needed to address water management problems in specific geographic areas within each AMA. Currently, management goals and programs apply to the entire AMA, regardless of local conditions. However, within AMAs areas exist with specific critical concerns. For example, hydrologic conditions can vary widely, from waterlogged areas to areas with severe groundwater overdraft that may result in land subsidence, earth fissures, and aquifer compaction. Areas of severe overdraft may compromise water supply reliability for local groundwater dependent users who may not have access to renewable water supplies. Salinity Salinity, or total dissolved solids (TDS) levels in CAP water, surface water and effluent typically 74 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 exceed that in native groundwater. As these supplies are increasingly utilized in the planning area, salinity levels will increase in both soil and groundwater. Human activities also contribute salts through industrial and commercial waste, water softeners and other wastes. It is estimated that 1.3 million tons of waterborne salts are annually transported into the Phoenix area from the Salt River and CAP canal and another 140,000 tons of salt are added annually from human activity. Studies suggest there is an annual net gain of approximately 1.1 million tons of salts in the Phoenix area and about 100,000 tons in the Tucson area. (USBOR, 2003) High salinity levels in water reduce its suitability for some uses or may require more extensive and expensive treatment. Salinity reduces the life of household appliances, may require water softening for some purposes, and reduces crop yields. Salt accumulation in agricultural area soils requires supplemental water to flush salts below plant root zones. Because salts become concentrated in wastewater, irrigation with reclaimed water may be problematic and its disposal increases salt-loading in groundwater. Typical TDS levels in Phoenix area reclaimed water range from 800 to 1400 mg/l compared to a range of 580 to 650 mg/l found in CAP water. Although not currently perceived as a critical issue, it is a growing concern that is being actively studied. (USBOR, 2003) 8.0.9 AMA Water Resource Characteristics Sections 8.1 through 8.5 present data and maps on water resource characteristics of the groundwater basins in the AMA Planning Area. A description of the data sources and methods used to derive this information is found in Section 1.3 of Volume 1 of the Atlas. This section briefly describes general information that applies to all of the basins and the purpose of the information. This information is organized in the order in which the characteristics are discussed in Sections 8.1 through 8.5. Geographic Features Geographic features maps are included to present a general orientation to principal land features, roads, counties and cities, towns and places in the groundwater basin. Land Ownership The distribution and type of land ownership in a basin have implications for land and water use. Large amounts of private land typically translate into opportunities for land development and associated water demand, whereas Federal lands are typically maintained for a public purpose with relatively little associated water use. State-owned land may be sold or traded, and is often leased for grazing and farming. The extent of State-owned lands is due to a number of legislative actions. The State Enabling Act of 1910 and the Act that established the Territory of Arizona in 1863 set aside sections 2, 16, 32 and 36 in each township to be held in trust by the State for educational purposes. Other legislation authorized additional State Trust Lands for specified purposes, which are identified for each basin (ASLD, 2006). Climate Climate data including temperature, rainfall, evaporation rates and snowfall are critical components of water resource planning and management. Averages and variability, seasonality of precipitation and long term climate trends are all important factors in demand and supply planning. Important in Section 8.0 Overview DRAFT 75 Arizona Water Atlas Volume 8 the AMA Planning Area is the heat island effect, which is affecting climate in the major metropolitan areas. Surface Water Conditions Depending on physical and legal availability, surface water may be a potential supply in a basin. Stream gage, flood gage, reservoir, stockpond and runoff contour data provide information on physical availability of this supply. Seasonal flow information is relevant to seasonal supply availability. Annual flow volumes provide an indication of potential volumetric availability. Criteria for including stream gage stations in the AMA tables are that there is at least one year of record, and annual streamflow statistics are included only if there are at least three years of record. There are different types of stations and those that only serve repeater functions were not included. Flood gage information is presented to direct the reader to sources of additional precipitation and flow information that can be used in water resource planning. Large reservoir storage information provides data on the amount of water stored in the basin, its uses, and ownership. Because of the large number of small reservoirs, and less reliable data, individual small reservoir data is not provided. The number of stockponds is a general indicator of small-scale surface water capture and livestock demand. Runoff contours reflect the average annual runoff in tributary streams. They provide a generalized indication of the amount of runoff that can be expected at a particular geographic location. Perennial and Intermittent Streams and Major Springs A map of perennial and intermittent streams is provided for each AMA. For some AMAs, more than one source of information was used. Stream designations may not accurately reflect current conditions in some cases. Spring data was compiled from a number of sources in an effort to develop as comprehensive a list as possible. Spring data is important to many researchers and to the environmental community due to their importance in maintaining habitat, even from small discharges. Groundwater Conditions Several indicators of groundwater conditions are presented for each AMA. Aquifer type can be a general indicator of aquifer storage potential, accessibility of the supply, aquifer productivity, water quality and aquifer flux. Well yield information for large diameter wells is provided and is generally measured when the well is drilled and tested and is reported on completion reports. It was assumed that large diameter wells were drilled to produce a maximum amount of water and, therefore, their reported pump capacities are indicative of the aquifer’s potential to yield water to a well. However, many factors can affect well yields including well design, pump size and condition and the age of the well. Reported well yields are only a general indicator of aquifer productivity and specific information is available from well measurements conducted as part of basin investigations. Natural recharge is often one of the least well known component of a water budget. Recharge estimates are generally from hydrologic studies conducted within the AMA. Water level data are from measured wells, usually collected during the period when the wells were 76 Section 8.0 Overview DRAFT Arizona Water Atlas Volume 8 not actively being pumped or only minimally pumped. Depth to water measurements are shown on mapped wells for the most recent measurement. The basin hydrographs show water-level trends for selected wells, typically over a 30-year period from 1975 to the year of most recent measurement, which varies between AMAs. The flow directions that are shown generally reflect long-term, regional aquifer flow in the basin and are not meant to depict temporary or local-scale conditions. However, flow directions in some AMAs indicate how localized pumping has altered regional flow patterns. Groundwater recharge is an important water management program in the AMAs and has had significant effects on groundwater levels at a number of locations. Permit information and the location of underground storage facilities and groundwater savings facilities where CAP water, effluent and surface water are stored for later recovery are shown on maps and tables. Water Quality Water quality conditions impact the suitability of water supplies for certain uses. Water providers serving more than 25 people or having 15 or more connections are regulated under the Safe Drinking Water Act and treat water supplies to meet drinking water standards (for more information see www.azdeq.gov). Water quality data were compiled from a variety of sources as described in Volume 1 Section 1.3. The data indicate areas where water quality exceedences have previously occurred, however additional areas of concern may currently exist where water quality samples have not been collected or sample results were not reviewed by the Department (e.g. samples collected in conjunction with the ADEQ Aquifer Protection Permit programs). It is important to note also that the exceedences presented may or may not reflect current aquifer or surface water conditions. Due to a high density of measured sites in the Phoenix, Pinal, Santa Cruz and Tucson AMAs, most sites within 0.75 miles of one another share a common map key. Also shown are contamination sites including DOD, RCRA, Superfund, WQARF, VRP and LUST sites including location, affected media and specific contaminant. Cultural Water Demand Cultural water demand, defined in the Atlas as municipal, industrial and agricultural water demand, is an important component of a water budget. Mandatory metering and reporting of water use in the AMAs has resulted in the collection of extensive and relatively accurate demand data. Municipal demand includes water company and domestic (self-supplied) demand estimates. AMA demand information is compiled from several sources in order to prepare as accurate an estimate as possible. Annual demand estimates have been averaged over a specific time period. This provides general trend information without focusing on potentially inaccurate annual demand estimates due to incomplete data or anomalous weather conditions in a single year. Locations of major cultural water uses are primarily from a 2004 USGS land cover study using older satellite imagery that may not represent recent changes. The cultural demand maps provide only general information about the location of water users. Effluent generation data were compiled from several sources to provide an estimate of how much of this renewable resource might be available for use. However, effluent reuse is often difficult to Section 8.0 Overview DRAFT 77 Arizona Water Atlas Volume 8 determine both logistically and economically since a potential user may be far from the wastewater treatment plant. Assured Water Supply Detailed information on Assured Water Supply (AWS) determinations for subdivisions, master planned communities and service areas are shown on maps and tables. Also shown are Water Adequacy Reports which were issued prior to enactment of the Groundwater Code in 1980. Change of ownership of a previously issued determination is not counted in the totals shown on tables and maps. Developers of subdivisions within AMAs are required to obtain a determination of whether there is sufficient water of adequate quality available for 100 years and that the development is consistent with the management plan and management goal of the AMA. In addition to these subdivision determinations for which a Certificate of AWS is issued, water providers may apply for assured water supply designations for their entire service area. If a subdivision is to be served water from a designated service area, then a separate Certificate of AWS is not required. Developers also have the option to obtain an Analysis of AWS, which is generally used to prove that water will be physically available for master planned communities. If an Analysis is issued for groundwater, it reserves a specific volume of water for 10 years for the specific property.

Flood ALERT equipment in the AMA is shown in Table 8.1-3. Flood ALERT equipment information is current up to October 2005. New flood warning gages are routinely added to the ALERT network so the current number of stations may be greater. Reservoir and stockpond data, including maximum storage or maximum surface area, are shown in Table 8.1-4. The location of streamflow gages identified by USGS number, flood ALERT equipment, USGS runoff contours and large reservoirs are shown on Figure 8.1-4. A description of stream data sources and methods is found in Volume 1, Section 1.3.16. A description of reservoir data sources and methods is found in Volume 1, Section 1.3.11. A description of stockpond data sources and methods is found in Volume 1, Section 1.3.15. Streamflow Data • Refer to Table 8.1-2. • Data from 35 stations located at 13 watercourses are shown in the table and on Figure 8.1-4. • Average seasonal flow varies and regulated releases from dams on the Salt, Verde, Gila and Agua Fria rivers influence the seasonal flow regime. On other drainages, average seasonal flows are generally greatest in the winter season (January-March). • The largest annual flow recorded in the AMA is 6.1 million acre-feet in 1993 at the Gila River at Estrella Parkway near Goodyear with a contributing drainage area of 45,585 square miles. Flood ALERT Equipment • Refer to Table 8.1-3. • There are 190 ALERT gages in the Phoenix AMA. Reservoirs and Stockponds • Refer to Table 8.1-4. • The AMA contains five large reservoirs. The largest by far is Lake Pleasant, which is actually located in the Agua Fria Basin. However, the dam that impounds Lake Pleasant, New Waddell, is located in the AMA. • Four reservoirs are used for recreation. Other reservoir uses include flood control, hydroelectric power generation, irrigation and water supply. • Surface water is stored or could be stored in 41 small reservoirs. • There are 711 registered stockponds in the AMA. Runoff Contour • Refer to Figure 8.1-4. • Average annual runoff is highest, 1 inch per year or 53.3 acre-feet per square mile, on the northeastern AMA boundary and decreases to 0.1 inches, or five acre-feet per square mile, in the center of the AMA.

The locations of major springs and perennial and intermittent streams are shown on Figure 8.1-5. A description of data sources and methods for intermittent and perennial reaches is found in Volume 1, Section 1.3.16. A description of spring data sources and methods is found in Volume 1, Section 1.3.14. • • • • • • • Principal perennial streams include the Verde River, Gila River and the Salt River. Only the Verde River is perennial throughout the AMA. Perennial flow in the Salt River and the Gila River below the 91st Avenue WWTP and 23rd Avenue WWTP is from effluent discharge. Flow in the Salt and Verde Rivers is dependent on releases from a series of upstream dams. Numerous intermittent streams are found in the southeastern portion of the AMA in the Superstition Mountains and in the northern portion of the AMA in the New River Mountains. There are two major springs with a measured discharge of 10 gallons per minute (gpm) or greater at any time located in the northeastern part of the AMA. Springs with measured discharge of 1 to 10 gpm are not mapped but coordinates are given in Table 8.1-5B. There are three minor springs. Listed discharge rates may not be indicative of current conditions. All of the measurements were taken during or prior to 1983. The total number of springs, regardless of discharge, identified by the USGS or ALRIS varies from 110 to 132, depending on the database reference.

Figure 8.1-6 shows aquifer flow direction and waterlevel change between 1991-1992 and 2002-2003 for the entire Phoenix AMA. Figures 8.1-6A-D show depth to water during 2002-2003 and water-level change between 1991-1992 and 2002-2003 for selected wells by sub-basin. Figure 8.1-7 contains hydrographs for selected wells shown on Figures 8.1-6A-D. Figure 8.1-8 shows well yields in five yield categories. Underground Storage Facilities (USF) and Groundwater Savings Facilities (GSF) are shown on Table 8.1-7 with facility name, facility permit number and type, permittee name, permitted acre-feet per year and water source. Locations of USFs and GSFs are shown on Figure 8.1-9. A description of aquifer data sources and methods is found in Volume 1, Section 1.3.2. A description of well data sources and methods, including water-level changes and well yields, is found in Volume 1, Section 1.3.19. Major Aquifers • Refer to Table 8.1-6 and Figure 8.1-6 • The major aquifers in the AMA are recent stream alluvium and basin fill. Groundwater is also found in sedimentary rock in some areas. • Groundwater flow has been artificially modified generally toward the Gila River drainage and groundwater pumping centers. Groundwater flow is toward cones of depression near Scottsdale, Mesa, and Queen Creek in the East Salt River Valley and to the southwest toward cones of depression in the Tonopah Desert and Centennial Wash area in the Hassayampa sub-basin. • In the West Salt River Valley sub-basin, the direction of groundwater flow originally was along the Salt and Gila Rivers into the Hassayampa sub-basin. Groundwater flow has been artificially modified toward cones of depression near Luke AFB and Deer Valley. • In the Fountain Hills sub-basin, groundwater flows to the south. (Not shown on map) • Groundwater flow in the Rainbow Valley sub-basin is to the northwest, in the Lake Pleasant sub-basin from north to south and in the Carefree sub-basin to the west-southwest. Well Yields • Refer to Table 8.1-6 and Figure 8.1-8 • As shown on Figure 8.1-8, well yields are generally greater than 1,000 gallons per minute (gpm). • One source of well yield information, based on 2,397 reported wells, indicates that the median well yield is 1,280 gpm. Natural Recharge • Refer to Table 8.1-6 • Natural recharge in the Phoenix AMA is 24,100 acre-feet per year. • Mountain front and streambed are the principal sources of natural recharge. Water Level • Refer to Figure 8.1-6A-D. Water levels are shown for wells measured in 2002-2003. Not all water level data shown on Fiugre 8.2-6 are shown on Figures 8.2-6 A-B. Section 8.1 Phoenix Active Management Area DRAFT 111 Arizona Water Atlas Volume 8 • • The Department annually measures 442 index wells in the AMA; hydrographs for 20 index wells are shown on Figure 8.1-7. The deepest water level shown is 866 feet in the vicinity of Cave Creek and the shallowest is 10 feet in the vicinity of Superior. Both wells are shown on Figure 8.1-7A. Recharge Sites • Refer to Table 8.1-7 and Figure 8.1-9. • There are 43 active USFs and 10 GSFs. • Total permitted storage capacity for USFs is 962,000 acre-feet per year. • Total permitted storage capacity for GSFs is 517,520.

Impaired lakes and streams with site type, name, length of impaired reach, area of impaired lake, designated use standard and parameter(s) exceeded is shown in Table 8.1-8B. Figures 8.1-10 and 8.1-10A show the location of water quality occurrences keyed to Table 8.1-8. Figures 8.1-11 and 8.1-11A show the location of contamination sites with site information show in Table 8.1-9. A description of water quality data sources and methods is found in Volume 1, Section 1.3.18. All community water systems are regulated under the Safe Drinking Water Act and treat water supplies to meet drinking water standards. Not all parameters were measured at all sites; selective sampling for particular constituents is common. Well, Mine or Spring sites that have equaled or exceeded drinking water standards (DWS) • Refer to Table 8.1-8A. • One thousand five hundred and seventeen sites have parameter concentrations that have equaled or exceeded DWS. • Frequently equaled or exceeded parameters include nitrate, fluoride, arsenic, manganese and organics • Other parameters equaled or exceeded include cadmium, lead, radionuclides, selenium, beryllium, chromium, total dissolved solids, mercury and barium, Lakes and Streams with impaired waters • Refer to Table 8.1-8B. • Water quality standards were equaled or exceeded in eight stream reaches and three lakes. The most common parameter equaled or exceeded was pesticides. • One reach, Queen Creek - from headwaters to the mining discharge, is part of the ADEQ water quality improvement effort called the Total Maximum Daily Load (TMDL) Program. Sampling is ongoing at the site at this time. Effluent Dependent Reaches • Refer to Figure 8.1-10A • There are four effluent dependent reaches in the AMA: Gila River, Salt River, Agua Fria River and Queen Creek. Contamination Sites • Refer to Figures 8.1-11 and 8.1-11A and Table 8.1-9 • There are 16 Voluntary Remediation Program sites, 12 Water Quality Assurance Revolving Fund sites, six active National Priority List sites and one Department of Defense Site. • The most common contaminants are Volatile Organic Compounds (VOCs).

Effluent generation including facility ownership, location, population served and not served, volume treated, disposal method and treatment level is shown in Table 8.1-11. Figure 8.1-12 shows the location of demand centers. A description of cultural water demand data sources and methods is found in Volume 1, Section 1.3.5. More detailed information on cultural water demands is found in Section 8.0.7. Cultural Water Demands • Refer to Table 8.1-10 and Figure 8.1-12. • Population increased from 1,522,577 in 1980 to 3,081,380 in 2000 and projections suggest an increase to over 8,076,000 residents by 2050. • Historically, agricultural water use has been the major demand in the Phoenix AMA; however, it has been steadily declining over time. At the same time, municipal and industrial demands are increasing. Average annual municipal demand in 2001-2003 increased by almost 36% over the previous decade. • During 2001-2003 approximately 44% of the total AMA cultural water demand was municipal and 47% of the total demand was agricultural. • The industrial sector accounted for approximately 9% of the total annual AMA water demand in the same time period. • As of 2003 there were 11,874 registered wells with a pumping capacity of less than or equal to 35 gallons per minute and 10,472 wells with a pumping capacity of more than 35 gallons per minute. Effluent Generation • Refer to Table 8.1-11. • 84 wastewater treatment facilities were identified in this AMA. • The largest treatment facility in the planning area is the 91st Avenue Treatment Plant operated by the City of Phoenix. It serves over 1.2 million people. • There are a wide range of effluent disposal methods in the AMA, with some of the most common being: discharge into an open water-course, golf course irrigation, permitted recharge, industrial reuse and crop irrigation. • More than 315,000 acre-feet of effluent is treated/produced annually. • Palo Verde Nuclear Power Plant reuses approximately 60,000 acre feet of effluent a year.

A determination of inadequacy could be due to insufficent physical or legal access to water or poor water quality. The Adequacy Program was replaced by the Assured Water Supply Program in the AMAs in 1980.

More detailed information on cultural water demands is found in Section 8.0.7. Cultural Water Demands • Refer to Table 8.2-10 and Figure 8.2-12. • Population in the Pinal AMA increased from 41,677 in 1980 to 89,032 in 2000 and projections suggest an increase to over 677,000 residents by 2050. • Agricultural water use is by far the largest demand in the Pinal AMA. Approximately 96% of the average annual demand was agricultural in 2001-2003. • Approximately 45% of the agricultural demand in 2001-2003 was met with groundwater. • Average annual municipal demand in 2001-2003 increased roughly 50% from a decade earlier. • The industrial sector accounted for approximately 1% of the total annual AMA water demand in the period between 2001-2003. • As of 2003 there were 1,770 registered wells with a pumping capacity of less than or equal to 35 gallons per minute and 2,956 wells with a pumping capacity of more than 35 gallons per minute. Effluent Generation • Refer to Table 8.2-12. • 21 wastewater treatment facilities were identified in the AMA. • There are a wide range of effluent disposal methods with some of the most common being: discharge into an open watercourse, golf course irrigation, permitted recharge, industrial reuse and crop irrigation. • More than 6,930 acre-feet of effluent are treated/produced annually in the Pinal AMA.

A determination of inadequacy could be due to insufficent physical or legal access to water or poor water quality. The Adequacy Program was replaced by the Assured Water Supply Program in the AMAs in 1980. 3 Session law from 1981 (HB 2465, Chapter 203) exempts subdivisions from the Assured Water Supply program where "substantial capital investment toward construction prior to 6/12/80 in addition to original cost of buying the land" has occurred.

Geographic features and principal communities are shown on Figure 8.5-1. The AMA is characterized by mid to high elevation mountains and broad alluvial basins. Vegetation types include Lower Colorado River and upland Sonoran desertscrub, southwestern grassland, southwestern interior chaparral, madrean evergreen woodland and small areas of petran montane conifer forest. Riparian vegetation is found along some watercourses, notably Sabino and Romero Creeks and at Arivaca Cienega (See Figure 8.0-10) • Principal geographic features shown on Figure 8.5-1 are: o The Santa Cruz River running south to north in the center. o Pantano Wash, Rillito Creek and Sabino Creek in the central eastern portion of the AMA and Altar and Brawley Wash in the west. o The Picacho Mountains and Black Mountain on the northern AMA boundary, the Santa Catalina, Rincon, and Santa Rita Mountains on the eastern boundary, the Sierrita and Santa Rita Mountains along the southern boundary, and the Baboquivari, Roskruge, Waterman and Silver Bell Mountains on the western boundary. o Altar Valley and Avra Valley in the western portion of the AMA and, though not specifically indicated, the Santa Cruz River Valley along the Santa Cruz River drainage in the center of the AMA. o The lowest point in the AMA at 1,770 feet, just north of Picacho Peak where Interstate 10 exits the AMA. o The highest point in the AMA at 9,453 feet at Mt. Wrightson in the Santa Rita Mountains. 352 Section 8.5 Tucson Active Management Area PRELIMINARY DRAFT Arizona Water Atlas Volume 8 Section 8.5 Tucson Active Management Area DRAFT 353 Arizona Water Atlas Volume 8 8.5.2 Land Ownership in the Tucson AMA Land ownership, including the percentage of ownership by category, for the Tucson AMA is shown in Figure 8.5-2.

A description of data sources and methods for intermittent and perennial reaches is found in Volume 1, Section 1.3.16. A description of spring data sources and methods is found in Volume 1, Section 1.3.14. • • • • • • Perennial streams include Romero Canyon, Sabino Canyon, Cienega Creek and Sycamore Canyon. An approximately 9-mile effluent-dependent reach of the Santa Cruz River is perennial due to discharges from the Roger and Ina Road WWTPs. Intermittent streams include the Santa Cruz River in the center of the AMA, and stream segments near the eastern AMA boundary and in Santa Cruz County. There are eight major springs with a measured discharge of 10 gallons per minute (gpm) or greater at any time. Springs with measured discharge of 1 to 10 gpm are not mapped but coordinates are given in Table 8.5-5B. There are three minor springs. Listed discharge rates may not be indicative of current conditions. Measurement dates are not available for six springs and the remainder were measured during or prior to 1982. The total number of springs, regardless of discharge, identified by the USGS or ALRIS varies from 162 to 187, depending on the database reference.

Effluent generation including facility ownership, location, population served and not served, volume treated, disposal method and treatment level is shown in Table 8.5-11. Figure 8.5-12 shows the location of demand centers. A description of cultural water demand data sources and methods is found in Volume 1, Section 1.3.5. More detailed information on cultural water demands is found in Section 8.0.7. Cultural Water Demands • Refer to Table 8.5-10 and Figure 8.5-12. • Population increased from 518,438 in 1980 to 853,423 in 2000 and projections suggest an increase to over 1.7 million residents by 2050. • Industrial water demand has and continues to be met almost exclusively by groundwater supplies. The major industrial users in the AMA are metal mines. In 2003 metal mines accounted for approximately 57% of the AMA’s total industrial water demand. • Municipal water demand is the major demand sector and is steadily growing, however; much of that growth is being offset with non-groundwater sources. The 1991-1995 average annual non-groundwater use in the municipal sector reflects direct delivery of CAP water. The 2001-2003 non-groundwater average annual use reflects CAP use through recharge and recovery. Effluent is also used to meet municipal demand. • Agricultural demand accounts for approximately 30% of the water demand in the AMA. • As of 2003 there were 6,443 registered wells with a pumping capacity of less than or equal to 35 gallons per minute and 4,930 wells with a pumping capacity of more than 35 gallons per minute. Effluent Generation • Refer to Table 8.5-11. • 24 wastewater treatment facilities were identified in the AMA. • A variety of effluent disposal methods are used in the AMA, with the majority of effluent discharged into the Santa Cruz River, stored at permitted recharge projects and used for golf course irrigation. • More than 74,000 acre-feet of effluent is treated/generated annually in the AMA.

Under the Ak-Chin Indian Community Water Rights Settlement Act of 1984, Pub. L. 98-530, the United States acquired 50,000 acrefeet (before losses) of Colorado River water from the Yuma-Mesa Division of the Gila Project, which was added to the CAP supply. Under the 1984 settlement, the Ak-Chin Indian Community is entitled to delivery of 75,000 acre-feet in a normal Colorado River water year, 85,000 acre-feet in a surplus year, and not less than 72,000 acre-feet in a shortage year. That obligation is met using first the former Yuma-Mesa water (quantified at 47,500 acre-feet after system losses) and thereafter as much of the original Ak-Chin allocation as is needed (27,500 acre-feet in a normal year). Whatever portion of the original Ak-Chin CAP allocation is not needed to satisfy delivery obligations to the Ak-Chin Indian Community (30,800 acre-feet in a normal year) is available for delivery to the San Carlos Apache Tribe (see note 3 below). 2 The Fort McDowell Indian Community was allocated 4,300 acre-feet in 1983. The Fort McDowell Indian Community Water Rights Settlement Act of 1990, Pub. L. 101-628, authorized the Secretary of the Interior to acquire the CAP non-Indian agricultural entitlement of the Harquahala Valley Irrigation District (originally 7.67% of the available agricultural supply) and convert it to 33,251 acre-feet of CAP Indian priority water. The Fort McDowell Indian Community received 13,933 acre-feet of the former HVID entitlement; the Gila River Indian Community received 18,100 acre-feet, and the remaining 1,218 acre-feet may only be used to settle water rights claims of other Indian tribes having claims to the water in the Salt and Verde River system. Appendix DRAFT 440 Arizona Water Atlas Volume 8 3 The Gila River Indian Community was allocated 173,100 acre-feet of irrigation water in 1983. Under an August 7, 1992 agreement among RWCD, the United States, and the Gila River Indian Community, RWCD purportedly relinquished the remainder of its CAP entitlement for the use and benefit of GRIC. The relinquished entitlement was quantified as 18,600 acre-feet and reallocated to the Community under §204(b)(1)(A) of the Arizona Water Settlements Act, Pub. L. 108-451. The Act also reallocated to the Community 18,100 acre-feet of the former HVID entitlement and 102,000 acre-feet of non-Indian agricultural priority water relinquished pursuant to the Arizona Water Settlement Agreement. See Pub. L. 108-451, §§204(b)(1)(B) and 204(b)(1)(D). 4 The San Carlos Apache Tribe was allocated 12,700 acre-feet in 1983. Of that total, 2,700 acre-feet was designated as irrigation water and 10,000 acre-feet was designated as tribal homeland water. Under the San Carlos Apache Tribe Water Rights Settlement Act of 1992, Title 37 of Pub. L. 102-575, the Secretary reallocated to the San Carlos Apache Tribe 14,665 acre-feet of CAP M&I water originally allocated to the Phelps Dodge Corporation, 3,480 acre-feet of CAP M&I water originally allocated to the City of Globe, and the portion of the original Ak-Chin CAP allocation not needed to meet delivery obligations to the Ak-Chin Indian Community (see note 1 above). In a normal water supply year on the Colorado River—i.e., when no more than 27,500 acre-feet of the original Ak-Chin allocation is needed for delivery to the Ak-Chin Indian Community—the San Carlos Apache Tribe allocation is 61,645 acre-feet. The former Phelps Dodge water and the former Globe water retain their original M&I CAP priority. 5 San Xavier was originally allocated 27,000 acre-feet and received an additional 23,000 acre-feet of nonIndian agricultural priority water relinquished pursuant to the Arizona Water Settlement Agreement. See §306(a)(1) of the Southern Arizona Water Rights Settlement Amendments Act of 2004 (Title 3 of the Arizona Water Settlements Act, Pub. L. 108-451). 6 Schuk Toak was originally allocated 10,800 acre-feet and received an additional 5,200 acre-feet of non-Indian agricultural priority water relinquished pursuant to the Arizona Water Settlement Agreement. See §306(a)(2) of the Southern Arizona Water Rights Settlement Amendments Act of 2004 (Title 3 of the Arizona Water Settlements Act, Pub. L. 108-451). 441 Appendix DRAFT
