PREFACE
This publication presents the surface water data collected by the Flood Control District of
Maricopa County's automated water-level gage network. This telemetered network is located
primarily throughout Maricopa County, Arizona with additional gages in Yavapai, Pinal, and La
Paz Counties.
The surface water data contained in this report were collected, compiled and edited by the
Flood Warning Branch of the Engineering Division. Data include mean daily, total, maximum,
and minimum discharges at the flow sites; mean daily, maximum, and minimum pool levels at
the storage locations; and mean daily, maximum, and minimum volumes stored at the storage
locations. Also included are maximum discharges, pool levels, and storage volumes for flood
events of interest at each site. Additionally, following the annual data is one or two graphics
representing the runoff / impoundment history for the station and, when available, a graphic of
the flood flow frequency with annual maximums. Flood flow frequency graphics are provided
for informational purposes only and should not be used for regulatory purposes, unless the
information is provided by a regulatory agency such as FEMA.
The information contained herein is as accurate and complete as possible within the limitations
of real-time data collection technology currently available. Wherever possible, notes have been
included to identify questionable data. Reliance upon the accuracy, reliability, and authority of

INTRODUCTION
The Flood Control District of Maricopa County in cooperation with federal, state, and
local agencies collects a large amount of data pertaining to surface water runoff in and
around Maricopa County. These data provide a valuable resource for information not
otherwise furnished by the traditional sources of this type of material. To make these
data readily available to interested parties outside the Flood Control District, the data
are published annually in this report entitled "Annual Hydrologic Data Report, Volume II
-- Surface Water and Streamflow Data." On-line users of this document have additional
resources available by selecting hyperlinks. Gage names will link to the web page for
that streamgage. Other hyperlinks will link within the document.
This report includes records on discharge at stream gages and at flood control storage
structures, on depths at flood control storage structures, and on contents at flood
control storage structures. Specifically it contains: (1) Streamflow records at 115
stream gages and 45 flood control storage structures; (2) Pool levels of stored water at
51 flood control storage structures; and (3) Storage volumes at 51 flood control storage
structures where stage-storage relationships are available. Records included are only
averages of data collected at each site during this water year.
Several streamflow gages are operated cooperatively between the FCDMC and the
United States Geological Survey (USGS). Although real-time data for these sites are
collected by the FCDMC ALERT System for the purposes of flood event monitoring,
quality control for the data at these gages lies with the USGS. The official records for
these sites are published in the USGS Surface Water Data Reports each water year or for
current data go to http://az.water.usgs.gov/. The cooperative gages collected jointly for
Water Year 2011 were:

ALERT water-level sensors are located on two Corps of Engineers structures. Tat
Momolikot and Whitlow Ranch Dams are monitored by the Corps of Engineers. Again,
these data are collected in real-time by the FCDMC for the purpose of flood monitoring.
The District will publish data for Tat Momolikot Dam since data are no longer collected
by the Corps. Please refer to the Los Angeles District office for official data for Whitlow
Ranch Dam at http://www.spl.usace.army.mil/resreg/.

This is the eighteenth annual surface water report published by the District. Prior to
water year 1994, surface water data collected by the FCDMC ALERT System were not
quality controlled, and therefore, not published. However, there are data resident in
archives prior to water year 1994 that may have value to specific individuals. Data are
available back to October 1987 for some stations.
The data are collected as a depth of flow in feet (or stage). The discharge and/or
contents is then obtained by applying the stage to a rating curve of stage versus
discharge in cubic feet per second (cfs), or stage versus contents in acre-feet (ac-ft). The
discharge rating curves have been developed at stream gages by using field surveyed
cross sections in a HEC-2 or HECRAS step-backwater computer model to obtain a range
of stage versus discharge points to be plotted on a curve. These step-backwater ratings
are refined whenever possible using direct and/or indirect measurements made at or
near the gage site. For flood control storage structures, discharge ratings were obtained
in one of two ways. First, the design ratings may be used. In most cases however, the
discharge rating curves were developed by application of the Federal Highway
Administration’s HY-8 computer model for culvert flow and U.S. Geological Survey
methods for weir flow over the uncontrolled emergency spillways. The storage rating
curves were obtained from published as-built or construction plans or developed from
digital elevation data.
Daily mean discharges are computed by applying the daily mean stages (gage heights) to
the stage-discharge curves or tables. A similar computation is done for storage facility
contents. The minimum and maximum values are based on instantaneous readings and
the volumes for discharge stations are based on accumulations of daily means. Those
gages in section 2, Pool Levels at Storage Facilities, which show a continuous gage height
during obvious periods of no storage, do so because the orifice of the pressure
transducer is set at that gage height above or below 0.0 feet gage datum.
All data in this report have been reviewed and edited in an attempt to provide the most
accurate data possible. A blank or blanks, represented with ---, within the data set is an
indication that data were lost either due to hardware, software, or radio problems, or
that the gage had not yet been installed. Where possible, these data are flagged with
footnotes describing the time the gage was down. In the event that published records
require revision, revisions are printed in later reports. Listed in the heading for each
gage where records have been revised are all the reports in which revisions have been
published for the station and the water years to which the revisions apply (e.g. WY1999:
WY1994-95 means that the data for Water Years 1994-1995 were revised in the report
for Water Year 1999).
Comments about this report or errors discovered may be sent to the Flood Warning
Branch via Internet e-mail from the FCDMC ALERT System Home Page or directly to

DEFINITION OF TERMS
Terms related to streamflow and other hydrologic data as used in this report are defined
below:
Acre-foot (ac-ft) is the quantity of water required to cover 1 acre to a depth of 1 foot
and is equivalent to 43,560 cubic feet or about 326,000 gallons or 1,233 cubic meters.
Contents is the volume of water in a reservoir or lake. Unless otherwise indicated,
volume is computed on the basis of a level pool.
Control designates a feature downstream from the gage that determines the stagedischarge relation at the gage. This feature may be a natural constriction of the
channel, an artificial structure, or a uniform cross section over a long reach of the
channel.
Control Structure as used in this report is a structure on a stream or canal that is used to
regulate the flow or stage of the stream.
Cubic Foot per Second (cfs) is the rate of discharge representing a volume of 1 cubic foot
passing a given point during 1 second and is equivalent to approximately 7.48 gallons
per second or 448.8 gallons per minute or 0.02832 cubic meters per second.
Cubic foot per second-day is the volume of water represented by a flow of 1 cubic foot
per second for 24 hours. It is equivalent to 86,400 cubic feet, approximately 1.9835
acre-feet, or about 646,000 gallons or 2,445 cubic meters.
Daily Mean Discharge is the average discharge in cfs for a 24 hour period from midnight
to midnight the following day.
Discharge is the volume of water (or more broadly, total fluid plus suspended sediment),
that passes a given point within a given period of time.
Drainage Area of a stream at a specified location is that area, measured in a horizontal
plane, enclosed by a topographic divide from which direct surface runoff from
precipitation normally drains by gravity into the stream above the specified point.
Drainage Basin is a part of the surface of the Earth that is occupied by a drainage
system, which consists of a surface stream or body of impounded surface water,
together with all tributary surface streams and bodies of impounded surface water.
El Niño is a condition where sea surface temperatures are warmer in the eastern Pacific
Ocean and cooler in the western Pacific Ocean in the lower latitudes. Normal conditions
of sea surface temperatures are opposite with warmer waters in the western Pacific and
viii

cooler waters in the eastern Pacific. El Niño conditions may result in higher than normal
precipitation in the southwestern United States.
Flood Elevation Frequency refers to the magnitude (in terms of depth or elevation) and
probability of floods at a given flood control impoundment structure. The flood
elevation frequency is usually given as a depth or elevation of impoundment associated
with a given recurrence interval at a particular flood control impoundment structure.
Flood Flow Frequency refers to the magnitude (in terms of peak discharge) and
probability of floods at a given gaging station. The flood flow frequency is usually given
as a peak discharge associated with a given recurrence interval at a particular gaging
station.
Gage Datum is the elevation of the zero point of the reference gage from which gage
height is determined. This elevation is established by a system of levels from known
bench marks or by approximation from topographic maps or arbitrarily established to a
known point such as a culvert invert elevation.
Gage Height is the water-surface elevation referred to some arbitrary gage datum.
Gage height is often used interchangeably with the more general term "stage," although
gage height is more appropriate when used with a reading on a gage.
Gaging Station is a particular site on a river, stream, canal, lake, or reservoir where
systematic observations of hydrologic data are obtained.
Instantaneous Discharge is the discharge at a particular moment in time.
La Niña is a condition where above normal sea surface temperatures exist in the
western Pacific Ocean and cooler than normal sea surface temperatures exist in the
eastern Pacific Ocean. La Niña conditions usually result in drier than normal conditions
in the southwestern United States.
Maximum Level is the highest pool level recorded or observed at a particular gaging
station at a flood control impoundment structure for a particular event.
Maximum Storage is the greatest volume of water stored behind or within a flood
control impoundment structure for a given event. This occurs at the maximum pool
level and is obtained from the stage-storage relation for that maximum level for a
particular flood control impoundment structure.
Mean Discharge (MEAN) is the arithmetic mean of individual daily mean discharges
during a specific period.

ix

National Geodetic Vertical Datum of 1929 (NGVD 1929) is a geodetic datum derived
from a general adjustment of the first order level nets of both the United States and
Canada. It was formerly called "Sea Level Datum of 1929" or "mean sea level."
Although the datum was derived from the average sea level over a period of many years
at 26 tide stations along the Atlantic, Gulf of Mexico, and Pacific Coasts, it does not
necessarily represent local mean sea level at any particular place.
North American Vertical Datum of 1988 (NAVD 1988) is a datum based on the mass or
density of the Earth instead of the varying values of the heights of the seas.
Measurements of the acceleration of gravity are made at observation points in a
network. Only one point is defined as the datum point. The vertical reference surface is
then defined by the surface on which the gravity values are equal to the datum point
value. This is called an equipotential surface.
Peak Discharge is the maximum instantaneous discharge for a given flood event.
Period of Record is the time period for which data exists for a given stream gaging
station.
Pressure Transducer is an instrument used to measure the depth of water. It is an
analog instrument which measures a pressure change over a diaphragm. The depth of
water is related to the change in pressure over the diaphragm created by the weight of
the water above the instrument.
Recurrence Interval is the reciprocal of the probability of a flood occurring in any given
year. Thus, the flood having a 1% (1/100, or 1 in 100) chance of occurring in any given
year has a recurrence interval of 100 years and is referred to as the 100-year flood.
Similarly, the flood having a 50% (1/2 or 1 in 2) chance of occurring in any given year has
a recurrence interval of 2 years and is referred to as the 2-year flood.
Staff Gage is a device located at the gaging station to provide a visual reference to the
depth of water at a gage in terms of gage height above the water level measuring
instrument.
Stage-Discharge Relation is the relation between gage height (stage) and the volume of
water, per unit of time, flowing in a channel or from a pipe or culvert.
Stage-Storage Relation is the relation between gage height (stage) and the volume of
water stored behind or within a flood control impoundment structure.
Streamflow is the discharge that occurs in a natural channel. Although the term
"discharge" can be applied to the flow of a canal, the word "streamflow" uniquely
describes the discharge in a surface stream course. The term "streamflow" is more

x

general than "runoff" as streamflow may be applied to discharge whether or not it is
affected by diversion or regulation.
Water Year dealing with surface-water data is the 12-month period, October 1 through
September 30. The water year is designated by the calendar year in which it ends and
includes 9 of the 12 months. Thus, the water year beginning October 1, 2010 and
ending September 30, 2011, is called the "2011 Water Year."

SUMMARY OF SIGNIFICANT STREAMFLOW EVENTS
Water Year 2011 got off to an exciting start, had an average beginning to the winter, but a
lackluster remainder of the year. It began right away with a rather memorable storm event on
October 5, 2010. In addition to the runoff, the big excitement was the hail and the damage it
caused. The fall and early winter showed a continuation of the propensity for rain and runoff to
occur. A small event occured on December 23, 2010 and was followed by a more significant
event on December 30. After this, the skies turned sunny and dry with no exceptional runoff
through the spring and with only a few small events occurring through early April.
The summer thunderstorm season was not notable either. Early July saw several decent runoff
events at stations in western Maricopa County and mid-September saw runoff at the gages
near Gila Bend.
Highlights of the runoff and impoundment events are summarized on the following two pages.

DATA PRESENTATION
The following three sections present the data collected by the Flood Control District ALERT
system. Data have been retrieved from a Hydrolynx® NovaStar 5 database, maintained at the
Flood Control District of Maricopa County.
The first section is Surface Water Streamflow data. This section contains data from free-flowing
stream sites and discharges from dams and detention basins. The second section contains Pool
Level data from storage structures, both dams and basins. The third section presents Storage
Volume data for both dams and basins. The data are in acre-feet of storage volume.
In the tables where there are dashes “- - -“ on a particular date or dates, the gage was down.
Typically a gage is down when the gage itself fails, or a transmitter or repeater fails. In the case of
transmitter failure or repeater failure, data for that date is available by manual download.
However, when no event has occurred, the data will typically not be retrieved from the device.

NOTE: Receding limbs of hydrographs may be significantly affected by clogging of outlet orifice. Therefore,
low flows for falling hydrographs may be unrealistically high. See downstream station 4823 for a better
representation of the falling limbs. Weir flow begins into main channel above 10 feet gage height.

Many days of impoundment due to irrigation tailwater. The gage is located inside a pump housing that, when
stage reaches a certain level, pumps water from the gage house and basin. The daily stage values fluctuate
substantially. Gage Heights above 10.0 feet are generally caused by storm events.

Many days of storage from irrigation tailwater. The gage is located inside a pump housing that, when stage
reaches a certain level, pumps water from the gage house and basin. The daily stage values fluctuate
substantially. Gage Heights above 10.0 feet are generally caused by storm events.

NOTE: Tie-in to Corps of Engineers gaging equipment was set up in August 2000. FCD gage was in operation
since January 8, 1998. All FCD data prior to August 2000 has been deleted because it is believed that the
gage did not operate correctly during that period. See U.S. Army Corps of Engineers, Los Angeles District for
official information at this gage site.
