Durango St., Phoenix, AZ 85009 (602) 506-1501 METEOROLOGY A very unique and uncharacteristic weather pattern for mid-August developed across AZ on August 19th. This event was highlighted by forcing from an approaching upper-level trough colocated over an unstable and moist atmosphere across south-central AZ. Multiple waves of training thunderstorms dropped heavy rainfall across the high terrain and lower deserts of central Maricopa County over a 12-hr period leading to a widespread flooding event. Synopsis: The synoptic setup on the morning of the event is shown in below in Figure 1. In the upper levels, a weakening Monsoon ridge can be seen centered over southern NM/west TX. Further to the west, an unseasonably strong upper-level trough was digging south off the coast of central CA. Additional inspection of the 500mb and 300mb maps also reveals a shortwave disturbance rotating around the base of the upper-level trough across the Lower Colorado River Valley into western and central portions of AZ. Forcing from this feature served as a catalyst to help initiate thunderstorms during the early morning hours of the event. Looking at the mid-levels, strong southwesterly flow was evident in both the 700mb and 850mb maps along with a distinct moisture axis located along the CA/AZ border. Surface moisture values were unseasonably high with surface dewpoints running in the upper 60s to low 70s across much of southern AZ. Precipitable water values were reported in the 1.87”-2.07” range through the morning or 1.75 times higher than normal for mid-August (NWS PHX). Water vapor imagery (courtesy of the NWS PHX) on the morning of the event depicted the aforementioned large scale features and distribution of moisture around the Desert Southwest. The atmospheric profile over Phoenix during the early morning hours was highly unstable as shown in the 12Z (5:00am MST) Phoenix sounding (Figure 2, below). Thermodynamic variables/indices of note include: the high CAPE/low CIN profile, negative lifted indices and highly elevated moisture variables. The wind profile was characterized by favorable vertical and directional wind shear, i.e. increasing magnitude and veering with height (clockwise turn), which is conducive for organized multi-cell thunderstorm development as opposed to typical Monsoon air-mass thunderstorms. Table 1 (below) shows values from the District’s hourly Convective Quantitative Precipitation Forecast at 5:06am MST. It was generated before the development of the first wave of thunderstorms that traversed the County. Of note, are the rather large 1-hr, 30-min, and 10-min potential rainfall rates throughout the District’s 16 forecast zones. These rain rates were indicative of the storm environment through the remainder of the morning and suggested heavy rainfall capable of widespread flash flooding. The large-scale setup and atmospheric profile discussed above closely resemble a Type IV transitional severe weather/flooding pattern most often seen during September at the end of the Monsoon season or during the fall months (uncommon for mid-August). One key component to this pattern worth noting again was strong mid and upper level southwesterly flow out ahead of the trough. On the day of the event, southwesterly steering flow provided two key mechanisms for storm enhancement: cell training (storms continuously redevelop over the same area) and orographic upslope enhancement (moist low-level flow is lifted up along the higher terrain areas to fuel developing thunderstorms). Both of these characteristics were observed through radar imagery and are referenced in subsequent sections. More information on severe weather/flooding patterns during the Monsoon season can be found here or by viewing Maddox et al. (1995). p. 3 FCDMC – 2801 W. Durango St., Phoenix, AZ 85009 (602) 506-1501 Storm Summary and Radar Imagery: The heavy rain that fell across the high terrain and lower deserts of central Maricopa County on August 19th came in approximately three waves roughly spanning a 12-hr period. A radar loop covering most of the event (3:00am-5:00pm MST) can be viewed using the following links (download format: .avi, .gif). The first wave of storms developed shortly after 5:00am MST west of the Loop 303 corridor and extended southeast into the Sierra Estrella range. Over the next 90 minutes these storms rapidly intensified as they moved northeast into the central Phoenix corridor. Further intensification occurred, aided by orographic lift, over the next hour as storms congealed into a well-organized cluster moving upslope into the higher terrain areas of north Phoenix, New River, Cave Creek, and north Scottsdale. Rainfall rates with this cluster peaked around 1.00”-2.50” per hour (image). The bulk of this wave moved east into the Verde River Valley by 8:30am MST. The second wave of thunderstorm activity was already underway by 8:00am. Thunderstorm initiation was occurring to the southwest of US 60/93 corridor from Wickenburg through the Wittmann area. Mid-level steering flow had shifted slightly from southwesterly to the west/southwesterly. This change in the flow created an optimal environment for continuous storm training and further orographic enhancement. Radar imagery (download format: .avi, .gif) from 8:30am-11:00am MST clearly showed a near steady-state pattern of continuous storms moving up and over the southern reaches of the Bradshaw Mountain range (Wickenburg and Hieroglyphic Mountains) east/northeast into the New River watershed. A secondary line of strong thunderstorms developed shortly after 11:00am MST extending from the Cave Creek Watershed southwest through the I-10 corridor in Glendale. These storms rapidly intensified as they moved east/southeast across the central and east Valley. Rainfall rates along this line peaked around the 0.75”-1.50” range per hour (image) before storms weakened passing through the Southeast Valley by 2:00pm MST. A radar loop covering the southern half of the second wave can be viewed using the following links (download format: .avi, .gif). A third wave of activity brought intermittent heavy rainfall from clusters of storms moving from west to east across the County. The leading edge of this third wave began moving through the Upper Centennial and Wickenburg areas by 2:00pm MST and then passed over New river by 3:00pm MST. Isolated clusters of storms then continued for the next four to six hours moving along the I-10 corridor from Tonopah through Tempe. The most notable round of storms in this wave developed over the White Tank Mountains around 6:00pm. Images of these storms as viewed from the District office can be view here. A Severe Thunderstorm Warning was issued by NWS Phoenix for these storms as they produced 50mph winds near Luke Air Force Based and dropped brief heavy rainfall over the El Mirage, Litchfield Park, Avondale and Laveen areas between 6:00pm-8:00pm MST. p. 4 FCDMC – 2801 W.

Although underestimating the rainfall in parts of central AZ, it alerted many emergency responders and the media to the severity of the expected rainfall in the coming days. p. 8 FCDMC – 2801 W. Durango St., Phoenix, AZ 85009 (602) 506-1501 FIGURE 5 Figure 5 above was created with ESRI ARCMap® using 24-hour rainfall totals from FCDMC ALERT gages and the “nearest neighbor” method to interpolate amounts between the gages. The estimated rainfall for Cooks Mesa, #5640, is included with the recorded gage amounts. The contours illustrate the effects of orographic lifting in this area of AZ when storms moving generally west to east from the deserts to the foothills dropping larger amounts of precipitation as they move upslope. p. 9 FCDMC – 2801 W.

These were chosen to represent the watersheds hit hardest by the storm, with the exception of #9 in the Upper AZ Canal Diversion Channel Watershed. In Tables II-X below, peak rainfall amounts for durations of 15 minutes to 24 hours were calculated for this storm. Also in Figure 6 is a yellow marker with a black “E”. This is the location of an FCD ALERT gage named “Cooks Mesa”, #5640. Cooks Mesa is at the very top of the New River watershed, and consistently records the highest rainfall amounts in the watershed during storms of this type. This is the only FCD rain gage that failed to operate during the storm. It is marked with an “E” for estimated, because data for this storm was entered into the ALERT database from the distribution for gage 4970 and an increase in depth of 5% - typical of previous storms. The effect of its missing data can be seen in Appendix A, Figure a), which was generated with a real-time data feed. Figure b in Appendix A adds evidence to past experience by showing rainfall estimates in the area unaffected by gage adjustment. p. 10 FCDMC – 2801 W. Durango St., Phoenix, AZ 85009 (602) 506-1501 Table II below is the NOAA Atlas 14 Point Precipitation Frequency Estimate Table at the latitude/longitude of the New River Mesa rain gage (4970). This gage is near the boundary between the Upper Cave Creek and Upper New River watersheds. The red row lists the recorded rainfall values from 08/19/2014. The blue row is the interpolated return period in years for each duration from 15 minutes to 24 hours. AEP is “Annual Exceedance Probability”. For this gage, we can surmise that the 6-hour duration rainfall scaled to a return period of slightly more than 500 years, although nearly all of that rain fell in a 4-hour period.

Durango St., Phoenix, AZ 85009 (602) 506-1501 FIGURE 16 Figure 16 above is a map showing contoured and colored values for the 6-hour, 100-year design rainfall from NOAA Atlas 14, Vol. 1, Version 5. It advises that in north-central Maricopa County the 6-hour, 100year design rainfall ranges from 3.0 to 3.5 inches. The red dots represent the FCDMC ALERT gage locations from Tables II-X (with the exception of Towers Mountain, which is off the map), and their corresponding peak 6-hour recorded rainfall amounts. As can be seen, several of these gages equaled or exceeded the 100-year frequency amounts. p. 20 FCDMC – 2801 W. Durango St., Phoenix, AZ 85009 (602) 506-1501 RUNOFF Watersheds in the northwestern, northern and northeastern parts of Maricopa County generated the greatest runoff. Beginning at the upper end of the New River Watershed, the FCD New River Fire gage did not record a reliable discharge because it was buried by sediment. High-water marks and a survey of the post-flood cross section suggest a discharge of 32,600 cfs. We can’t assign a reasonable return period to this discharge because of the short gage record, but it is by far the largest recorded discharge since the gage was installed in July of 2005. The USGS “New River near Rock Springs, AZ” gage was destroyed by this flood. USGS conducted an indirect measurement survey (IMS) at the gage location and reported a peak discharge of 52,000 cfs. This represents a return period of approximately 320 years interpolating from table values in USGS StreamStats. Further downstream, the USGS conducted another IMS at the New River Elementary School. The result was 39,300 cfs – much higher than the 100-year discharge from the FEMA Flood Insurance Study (FIS) maps at this location of 32,000 cfs. Finally, New River Dam impounded 5,620 acre-feet of water at a stage of 30.38 feet – 12.9% of its emergency spillway capacity. In the Skunk Creek watershed, Skunk Creek near New River recorded a peak discharge of 1,054 cfs representing a return period of 8 years. Cline Creek, the largest tributary to Skunk Creek, had a peak discharge of 5,070 cfs by FCDMC IMS at the gage site – a return period of about 50 years and by far the largest flow recorded at the gage since installation in November of 2001. The USGS conducted an IMS at Cline Creek at New River Road which yielded a peak of 7,200 cfs. The FEMA FIS 100-year discharge at New River Road is 13,747 cfs. Further downstream, Skunk Creek flooded the west-bound approach to Carefree Highway before heading down to Dove Valley Road, where a USGS IMS gave a peak discharge of 18,700 cfs. The FEMA FIS 100-year discharge at Dove Valley Road is approximately 27,000 cfs. Below Dove Valley Road at Dixileta Dr., the flow in Skunk Creek split, with most going down the channel, but some going down the northbound lane of I-17 and some into the CAP Canal. By the time it reached the crossing of I-17, the peak discharge passing the combined FCDMC/USGS gage had dropped to approximately 13,000 cfs – a return period of about 20 years. Finally, Adobe Dam impounded 990 acre-feet of water at a stage of 13.95 feet – 5.3% of its emergency spillway capacity. Further east in upper Cave Creek, the FCDMC gage on Seven Springs Wash measured 1,090 cfs – less than a 2-year event. Discharge picked up further down at the Ashdale Ranger Station, where an FCDMC gage reported a peak of 8,735 cfs. This gage has a short record, but this is the highest recorded discharge since installation in Feb. 2009. Near Spur Cross Road, both the USGS and FCDMC gages failed to operate. An IMS by USGS calculated a peak discharge of 9,240 cfs at this location, representing a return period of 16 years. In the Town of Cave Creek, the FCDMC “Cave Creek” gage returned a peak discharge reading of 17,190 cfs – a return period of nearly 30 years. The previous highest discharge at this site was 15,900 cfs on Jan. 21, 2010. Below Carefree Highway, a FCDMC gage read 14,740 cfs – a bit over a 30-year return period but somewhat lower than the 15,000 cfs registered on Jan. 21, 2010. Lastly, Cave Buttes Dam impounded p. 21 FCDMC – 2801 W. Durango St., Phoenix, AZ 85009 (602) 506-1501 1,977 acre-feet of water at a stage of 36.77 feet – 4.3% of its emergency spillway capacity. A question has been raised concerning these high peak discharges on watercourses feeding the large Corps dams (Adobe, New River and Cave Buttes), but the relatively small amounts of impounded runoff compared to their design capacity (see Table XI). The storm Adobe Dam design storm used a 6-hour local storm much like this event, but it generated 3.53 inches of rainfall excess and a peak inflow discharge of 66,000 cfs. The storm for New River Dam had a 72-hour rainfall distribution that simulated nearly 8 inches of rainfall excess in the upper watershed and 3.8 inches in the lower, generating a peak of 45,000 cfs. For Cave Buttes Dam, the USCOE again used a 72-hour storm generating 4.14 inches of rainfall excess and a peak discharge of 54,000 cfs. For comparison, the average 6-hour rainfall over the Cave Creek Watershed for this storm was about 3 inches, so the rainfall excess would have been about 1.5 inches. To see the areas of greater Phoenix protected by the large Corps dams working in concert with the AZ Canal Diversion Channel as a principal outlet, please see Appendix B. The Hassayampa watershed begins its southward journey in southern Yavapai County. The uppermost gage, Hassayampa River @ Wagoner Rd., showed a discharge of only 307 cfs – less than a 2-year event. North of Wickenburg, the Box Canyon gage recorded a peak of 3,660 cfs, a 2-year event. At Wickenburg, the River is met by a major tributary – Martinez Creek. Martinez Creek itself had a peak flow measurement of 7,600 cfs, nearly a 10-year return period, and its tributary Antelope Creek recorded 3,580 cfs, also an approximate 10-year event. Further down at Morristown, the Hassayampa River showed a peak flow of about 4,700 cfs by both the FCDMC and USGS gages – a 3-year event. FCDMC stream gages that were not functional during the event were Cave Creek @ Spur Cross Rd. (4923, failure of USGS recording equipment), New River Dam Outlet (5613, critical electrical component got wet), Hassayampa River at US60 (5228, vandalized), and Stagecoach Wash (4913, unknown – gage tested OK after event).

For this storm, we present the three major watercourses in north-central Maricopa County – New River, Skunk Creek and Cave Creek. New River above Carefree Hwy. The rain gages in this watershed had an average duration for the heaviest rainfall of 4.5 hours, with an average of 0.26 inches outside that 4.5 hours. The calculated average rainfall includes the estimated rainfall for gage #5640 at the top of the watershed. The MCS2I parameters are 3.07 inches in 4.5 hours over 152 square miles. Its MCS2I score is 8.1 p. 27 FCDMC – 2801 W. Durango St., Phoenix, AZ 85009 (602) 506-1501 Skunk Creek above Carefree Hwy. The rain gages in this watershed had an average duration for the heaviest rainfall of 5 hours, with an average of 0.38 inches outside that 5 hours. So the MCS2I parameters are 2.66 inches in 5 hours over 49 square miles. Its MCS2I score is 7.7 p. 28 FCDMC – 2801 W. Durango St., Phoenix, AZ 85009 (602) 506-1501 Cave Creek above Carefree Hwy. The rain gages in this watershed had an average duration for the heaviest rainfall of 5 hours, with an average of 0.33 inches outside that 5 hours. So the MCS2I parameters are 2.58 inches in 5 hours over 122 square miles. Its MCS2I score is 7.5 p. 29 FCDMC – 2801 W. Durango St., Phoenix, AZ 85009 (602) 506-1501 SELECTED DATA SOURCES 1.

Durango St., Phoenix, AZ 85009 (602) 506-1501 APPENDIX C FCDMC ALERT Operations Center Narrative The ALERT Operations Center (AOC) is an extension of the Flood Control District’s “ALERT Room”. When warranted by a severe and/or long-term rainfall event, the AOC is staffed by an Incident Commander and representatives from Dam Safety, Operations & Maintenance, GIS and an Event Historian. The AOC staff’s main objective is to provide decision support to our Emergency Management and other County departments, and to manage the operation of our own flood control structures. The following narrative is the account of AOC Operations by our Event Historian. th On Tuesday, August 19 , heavy rains measuring up to three inches in the Hassayampa watershed and up to four inches in the New River, Skunk Creek and Cave Creek watersheds prompted a partial activation of the Maricopa County Department of Emergency Management’s (MCDEM) Emergency Operations Center (EOC) at 10:30am. The Flood Control’s ALERT Operations Center (AOC) was activated shortly thereafter, at 10:50am, to monitor rainfall gauges, streamflow gauges, and dam impoundment levels across the county, as well as to send out Operations and Maintenance (O&M) crews to observe field conditions in critical areas. This information was provided to the EOC to assist their management of the emergency situation. During the six hours that the AOC was activated, it received calls from law enforcement agencies, school districts, CAP employees, members of county and state departments, and private businesses looking for information and guidance on how to best handle the storm. Due to the training and efficiency of the employees of the Flood Control District staffing the AOC, all interested parties received accurate, dependable information in a timely manner, so they could properly respond to the storm. At the time of activation of the AOC, it was anticipated that rainfall would continue for the next three hours. The flow in Skunk Creek at I-17, which had attracted significant media attention, had maxed out at 12,000 cfs prior to AOC activation. Heavy rain was falling in the Cave Creek Watershed, so the potential for flooding issues later in the day in this area was high. In Skunk Creek at the CAP canal, it appeared as though the creek was flowing around the overchutes and along or potentially into the canal, so an O&M crew was sent out to monitor the situation. Minor flooding had been reported at the Sage Apartment complex, south of the CAP canal along the east side of I-17, so the Sherriff’s department had sent out someone to assess the extent of the flooding. At the time of activation, police were already on site at reported flooded areas to assist in barricading roads if necessary. Cave Buttes Dam was at 13’ deep (5% full), Adobe Dam was at 12’ deep (5% full), and New River Dam had no inflows, but that was expected to change. Between 11am and noon, the AOC received a notification that Wet’n’Wild, located within the Adobe Dam impoundment area, had evacuated all employees except one security guard. A Deputy with the Sherriff’s department was sent to close down the th rd trails along and within Skunk Creek between 75 Avenue and 83 Avenue. The construction of the Loop 303 outfall channel near MC85 and Cotton Lane was shut down due to the rain. The Flood Control District sent two employees to the EOC in order to more efficiently pass information between the two agencies. There was a briefing at 12:20. Adobe Dam was at 11.6’ deep (5% full), Cave Buttes Dam was at 11.5’ deep (5% full), and New River Dam had begun receiving flows, and was now at 6.3’ deep (<1%). South Central Phoenix was expecting to receive heavy rainfall, and Indian Bend Wash was anticipated to receive substantial flow. There were three O&M crews in the vicinity of Skunk Creek and Adobe Dam. They had cleared out the side inlets to Skunk Creek at the Sage Apartment Complex, and had cleared out a drain downstream of I-17 on Skunk Creek. An additional team had arrived at Cave Buttes Dam and was monitoring the situation there. In the early afternoon, a streamflow gauge on Cave Creek just downstream of Carefree Highway reported a flow in the creek of 26,000 cfs (as of this writing, we are working on field verification by survey, which may show the peak to have been less than 20,000cfs). For reference, the 100-year peak flow in the creek is 33,800 cfs. A member of the Scottsdale Police Department contacted the Flood Control District to determine the impacts of large amounts of water entering Indian Bend Wash. Flood Control District staff instructed the police office on how to access the Flood Control District’s website to view data from p. 34 FCDMC – 2801 W. Durango St., Phoenix, AZ 85009 (602) 506-1501 streamflow gauges across the county. An O&M team had arrived at the western CAP canal chute and determined that there were no issues there. Another briefing was held at 1:20pm. The storm was moving northwest, towards the Wickenburg area. A crew at Cave Buttes dam reported a depth of 13.5’, and more water was expected. The crew at Adobe dam reported a depth of 13.5’. New River dam was at a depth of 12’. Dreamy Draw dam was letting out a small amount of water into the Arizona Canal Diversion Channel th (ACDC) near 16 Street. New River Elementary School, located on the east side of I-17 just north of West New River Road, was put on standby for evacuation. Employees in the AOC determined that the peak flow in New River had already passed the school, and had been at 15,000 cfs, which is approximately half of the 100-year flow. The school building is not in the floodplain, so it should not have been affected by the water, other than to monitor for bank erosion. Concerned about the potential impacts to the Agua Fria River, a flood control employee contacted the CAP command center to find out if there were any planned releases into the river from Lake Pleasant. There were none, and CAP had an additional 40’ of storage in Lake Pleasant. At approximately 2:30, the AOC received reports of water seeping at the abutment of Cave Buttes Dam, so FCD staff was sent to determine the severity of the leak. At approximately 2:45, the AOC received a message from a member of the Parks Department requesting information on the status of Adobe Dam. A member of the Flood Control District replied telling her that the dam was 5.2% full with more water expected. She was told that the expected time to empty would be approximately 20 hours, but FCD Staff recommended that she call in the morning for an update. At approximately 3pm, another storm began developing over Lake Pleasant, with three smaller storms behind it. These were anticipated to be much smaller than the earlier storms, and to last until 6pm. O&M crews had determined that the leak at Cave Buttes Dam was actually just flow off debris on the dry side of the dam, and was nothing to be concerned about. At New River Elementary, an O&M crew was sent to investigate a report of erosion along the bank of the river. A deputy monitoring the situation at New River Elementary reported a 6-8” rise in the water level over the past hour, however neither the rainfall gauges in the area nor the streamflow gauges in the area reported any data to substantiate this report. The AOC received a call from Deer Valley School District Disaster Relief, asking if they should close the school tomorrow. The question was sent to the EOC so they could advise the School District. At 4:30, the EOC contacted Deer Valley SD and advised them to have an inspector examine the riverbank and determine if the school should be closed the following day. At 3:30, the water level in Cave Buttes dam reached the principal outlet. New River dam was at 27’ deep, 10% full. At approximately 4pm, another briefing was held. A storm over the New River and Cave Creek watersheds was expected to drop between ½” and 1” of rain on these areas over the following hour. Another storm, stretching from Wickenburg to the Upper Centennial Watershed, was not expected to create as much rainfall. All O&M crews had been recalled from the field, but the head of the our Flood Warning Branch recommended keeping the AOC and EOC staffed until this group of storms passed. Later in the afternoon, the AOC received reports about the Adobe Dam outflow flooding downstream roads. This was to be expected, and should last for the following 24 hours. The Department of Emergency Management deactivated the EOC at 4:40. At 5pm, the AOC received a call from CAP asking for information on the flooding on I-17 in the vicinity of the CAP canal. FCD Staff called him back and informed him of what was observed earlier in the day. CAP requested that they be involved in any meetings with ADOT and the City of Phoenix regarding the event in this area. The AOC was deactivated at 5:28pm. p. 35 FCDMC – 2801 W.
