SURFACE WATER SUPPLY OF THE COLORADO RIVER BASIN, 1945

SCOPE OF WORK

This volume is one of a series or 14 reports presenting results or measurements or 

stage and flow made on streams, lakes, and reservoirs In the United States during the 

water year ending September 30, 1945. The work was begun In 188S In connection with 

special studies relating to Irrigation. Measurements of ttie flow of streams and of the 

stage and contents of lakes and reservoirs have been made at about 10,300 gaging stations 

In ttie 48 States and also at many In the Territories of Alaska and Hawaii. In July 1945, 

5,600 gaging stations, including those In Hawaii, were being maintained by the Geological 

Survey and cooperating organizations. Miscellaneous discharge measurements were made 

during the water year at many other points.

In the execution of the work many State and private organizations have cooperated, 

either by furnishing data or by assisting In collecting data. Cooperation of the first 

kind Is acknowledged In connection with the description of each station affected; cooperation of the second kind Is acknowledged, under the heading "Cooperation," In the Introductory matter that precedes ttie gaglng-statlon records In each volume. In the present 

volume, the section on cooperation of the second kind appears on page 11.

DEFINITION OF TERMS

The units In which stream-flow data are presented In this report and other terms used 

herein are defined as follows:

"Second-feet" Is an abbreviation for "cubic feet per second." A second-foot Is the 

rate of discharge of a stream whose channel Is 1 square foot In cross-sectional area and 

whose average velocity Is 1 fcot per second.

"Second-feet per square mile" is the average number of cubic feet of water flowing per 

second from each square mile of area drained, on the assumption that ttie runoff Is distributed uniformly both as regards time and area.

"Runoff In Inches" is the depth to which an area would be covered If all ttie v/ater 

draining from It In a given period were uniformly distributed on Its surface. It Is used 

for comparing runoff with rainfall, which Is usually expressed In Inches.

An "acre-foot" is the quantity of water required to cover an acre to ttie depth of 

1 foot and Is equivalent to 43,560 cubic feet. The term Is commonly used In connection 

with storage for Irrigation.

"Second-foot-day" Is ttie volume of water represented by a flow of 1 second-foot for 24 

hours. It Is equivalent to 86,400 cubic feet, 1.983471 acre-feet, or 646,317 gallons and 

represents a runoff of 0.0372 Inch from 1 square mile.

"Stage-discharge relation" Is an abbreviation for the term "relation between gage height 

and discharge."

"Control" Is a term us~ed to designate a feature downstream from the gage that determines 

the stage-discharge relation at ttie gage. This feature may be a natural section, a reach 

of the channel, or an artificial structure.

2 SURFACE WATER SUPPLY, 1945, PART 9

"Contents" is a term applied to the volume of water In a reservoir. It Is computed on 

the basis of a level pool and does not Include bank storage unless otherwise Indicated.

EXPLANATION OF DATA

The base data collected at gaging stations consist of records of sta^e, measurements of 

discharge, and general information used to supplement the records of stage and discharge 

measurements In determining the dally flow. The records of stage are obtained either from 

direct readings on a nonrecording gage or from a water-stage recorder that gives a continuous record of the fluctuations. Measurements of discharge are made with a current 

meter by the general methods outlined In standard textbooks on the measurement of river 

discharge. Typical structures In use at gaging stations are shown In figure 1.

Rating tables giving the discharge for any stage are prepared from the discharge measurements. The application of the dally mean gage height to those rating tables gives the 

dally mean discharge, from which the monthly and the yearly mean discharge are computed. 

If the stage-discharge relation is subject to change because of frequent or continual 

change in the physical features that form the control, the dally mean discharge is determined by the "shiftIng-control method," In which correction factors based on individual discharge measurements and notes by engineers and observers are used In applying the 

gage heights to the rating tables. At times the stage-discharge relation for a station 

may be temporarily changed by the presence of aquatic growth or debris on the control. 

For such times the daily mean discharge is computed by what is essentially the "shiftingcontrol" method, described above.

At some gaging stations the stage-discharge relation is affected by backwater from 

reservoirs, tributary streams, or other.sources, which necessitates the use of the "slope 

method," in which the slope or fall in a reach of the stream is a factor in the determination of discharge. Information requisite for determining the slope or fall is obtained 

by means of an auxiliary gage set at some distance from the base gage. At some stations 

the stage-discharge relation is affected by changing stage, and for them the rate of 

change of stage is used as a factor in the determination of discharge.

At most gaging stations in the northern part of the United states and at some In the 

mountainous regions of other parts the stage-discharge relation Is affected by ice during 

the winter, which makes it impossible to compute the discharge in the usual manner. Discharge for periods of ice effect is computed on the basis of the gage-height record and 

occasional winter discharge measurements, consideration being given to the available information on temperature and precipitation, notes by gage observers and engineers, and 

comparable records of discharge for stations in the same or nearby basins. For those 

stations at which the etage-discharge relation is affected by ice, the days included in 

the periods of ice effect either are indicated in the table by symbols referring to a 

footnote that states this fact or are given In a general note following the table. The 

days on which discharge measurements were made during or between periods of ice effect, 

shortly before the first period, or shortly after the last period are similarly Indicated 

by a footnote.

For most of the gaging stations on streams In the area covered by this report the data 

presented comprise a description of the station, a table showing the daily discharge of 

the stream, and a table of monthly and yearly discharge and runoff. Skeleton rating

tables are published for all stations except those at which the dally discharge for the 

greater part of the year was determined by the shifting-control method, the slope method, 

or other special methods.

The description of the station gives the type of gage, Its latitude and longitude as 

determined from the best available maps, and Information In regard to diversions that 

decrease the flow at the gage, artificial regulation from pondage or storage, and the 

accuracy of the records. Under "Average discharge" Is given the average discharge for the 

number of years Indicated. It Is given only for stations for which there are 10 or more 

complete years of record. Under "Extremes" are given the maximum discharge and gage height; 

tee minimum discharge if there Is little or no regulation; the minimum daily discharge if 

there is extensive regulation (also tee minimum discharge if use.ful); and the minimum gage 

height (unless it is of no importance). Unless otherwise qualified, the maximum discharge 

corresponds to the crest stage, obtained by use of a water-stage recorder or a nonrecording gage read at the time of the crest. Likewise the minimum discharge represents the 

lowest stage, unless otherwise qualified, selected peak discharges with tee times of 

their occurrence are given, below the table of monthly discharge, for some stations. This 

supplementary Information Is generally omitted for a station at which tee drainage area of 

the stream Is less than 10 or more than 10,000 square miles or at which, on most days, the 

peak discharge exceeds tee mean discharge by less than 10 percent.

For stations equipped with water-stage recorders, except those on streams subject to 

sudden or rapid fluctuation, the table gives the discharge corresponding to the dally mean 

gage height. For stations subject to such fluctuation the daily mean gage height may not 

Indicate the true daily mean discharge, which must be obtained by averaging the discharge 

for parts of tee day or by using the discharge integrator, an instrument for obtaining the 

daily mean discharge from a continuous gage-height graph and containing as an essential 

element a curve representing the stage-discharge relation at the station. For stations 

equipped with nonrecording gages, the table of dally discharge gives the discharge in 

second-feet corresponding to once-daily readings of the gage or the mean of twice-daily 

readings. For periods of rapidly changing stage tee dally mean discharge is determined 

from gage-height graphs based on gage readings made once or twice daily or oftener, as 

stated In the station description.

In the table of monthly discharge the column headed "Second-foot-days" gives the sum 

for each month of the figures given in the table of dally discharge. The column headed 

"Maximum" gives the maximum daily discharge, not the momentary discharge when the water 

surface was at crest stage. Likewise, in the column headed "Minimum" the quantity given 

is tee minimum daily discharge. The column headed "Mean" gives the average flow In cubic 

feet per second during the month.

For most gaging stations on lakes and reservolre the data presented comprise a description of tee station and a monthly summary table of stage and contents. For some reservoirs 

a table showing dally contents is given. A skeleton table of capacity at given stages is 

usually given-In the first report in which data for a station are published but Is omitted 

from succeeding reports.

TIME BASIS

At 2 a.m. on February 9, 1942, as an emergency measure, the Nation shifted from 

standard time to "war time," and clock time In the several zones of the country was noved 

ahead 1 hour, or to 3 a.m. At 2 a.m., war time, on September 30, 1945, a change was made 

back to standard time and clock time was moved back 1 hour, or to 1 a.m. This made September 30 a 25-hour day. Time given herein for the water year 1945 prior to the change on
PUBLICATIONS 5

September 30 refers to war time; time after the change refers to standard time. To convert 

war time to standard time, subtract 1 hour. Records of dally discharge prior to February 9, 

1942, were computed, and those subsequent to September 30, 1945, will be computed on the 

basis of standard time; records between those dates were computed on the basis of war time. 

The discharge given for September 30, 1945, Is the mean for 25 hours. The mean discharge 

and runoff for the month of September have been computed from the total second-foot-days 

for the month without adjustment for the fact that September 30 was a 25-hour day. The 

small error resulting from this procedure has been disregarded.

The State of Arizona changed official time from war time to standard time January 1,1944, 

except for the period April 1 to September 30, 1944, which was war time. For stations In 

Arizona, records from February 9, 1942, to December 31, 1943, were computed on the basis of 

mountain war time, and those subsequent to this period were computed on the basis of 

mountain standard time.

ACCURACY OF FIELD DATA AND COMPUTED FESULTS

The accuracy of stream-flow data depends primarily on (1) the permanency of the stagedischarge relation or, If the control Is unstable, the frequency of discharge measurements 

and (2) the accuracy of observations of stage, measurements of flow, and Interpretation of 

records.

The station description gives a statement in regard to the general accuracy of the 

records. "Excellent" indicates that, in general, the error In the dally records Is 

believed to be less than 5 percent; "good," less than 10 percent; "fair," less than 15 percent; and "poor," probably more than 15 percent. The records of monthly and yearly mean 

discharge and runoff are, In general, more accurate than the daily records.

Yield at some stations as Indicated by monthly means may vary widely from natural yield, 

owing to diversion, consumption, regulation by storage, Increase or decrease In evaporation 

due to artificial causes, or other factors. For such stations figures of "second-feet per 

square mile" and "runoff in inches" are not published unless storage or diversion records 

are included indicating the extent of the regulation or diversion or unless satisfactory 

adjustments can be made for changes In contents or reservoirs or for other changes incident 

to use and control. Evaporation from a reservoir Is not included in the adjustments for 

changes in reservoir contents, unless Its Inclusion is indicated. Figures of second-feet 

per square mile and runoff In inches are also omitted if the drainage area Includes large 

noncontrlbutlng areas or if the average annual rainfall over the drainage area is less 

than 20 inohes.

Many gaging stations on streams In the Irrigated areas of the United States are situated above most of the diversions from those streams, and therefore the discharge recorded 

does not show the water supply available for further development, as prior appropriations 

below the station must first be satisfied.

The table of monthly discharge presents In summary the distribution of the flow past the 

station. The table of daily discharge affords opportunity for more detailed studies of the 

variation in flow. As further observations in each succeeding year may be expected to 

throw new light on data previously published, it should be borne in mind that such data are 

subject to revision in succeeding water-supply papers.

Papers on surface water supply containing records from 1899 to date, grouped by years 

and drainage basins, are listed by number on page 8. The data for any particular gaging 

station will, in general, be found in the reports covering the years during which the 

station was maintained. For example, the data for 1910 to 19£0 for any station In the 

area covered by part 3 are published in Water-Supply Papers £83, 303, 323, 353, 403, 433, 

453, 473, and 503, which contain records for the Ohio River Basin for those years.

The records at most of the stations discussed in these reports extend over a series of 

years. Miscellaneous measurements at many points other than regular gaging stations have 

been made each year and are published under "Miscellaneous discharge measurements" at the 

end of each report, the streams and points of measurement listed appearing in the same 

relative order as the streams and gaging stations in the body of the report. An index of 

the records, obtained prior to 1904 has been published In Water-Supply Paper 119.

Each of the reports on surface water supply for the year 1939, Issued as Water-Supply 

papers 871 to 884 (see table on p. e), contains, for the area covered by that report, a 

summary of yearly discharge at gaging stations at which 10 or more complete years of 

record have been collected. These summaries are available also as separate reprints.

RECORDS OF DISCHARGE COLLECTED BY AGENCIES OTHER THAN THE GEOLOGICAL SURVEY 

The v/estern Colorado Power Co. continued, during the water year October 1944 to September 1945, to collect records of dally discharge for Cascade Creek near Tacoma, Colo., 

which now cover the years 1915-45. The records' for the years 1934-40 are published In the 

surfacs water-supply papers of the Geological Survey covering the Colorado River Basin for 

those years, and the records for the entire period are on file at the Office of the State 

Engineer of Colorado. The Soil Conservation service of the United States Department of 

Agriculture collected records of runoff from 4 areas of less than SOO acres each in the 

vicinity of Safford, Arizona. These records now cover the years 1938-45 and are available 

In the files of the Soil Conservation Service.

COOPERATION

The work In the several States was done under cooperative agreements with the organizations listed below:

Arizona: State Land Department, 0. C. Williams, Commissioner; Salt River Valley 

Uater Users' Association; Metropolitan Water District of Southern California (for 

certain stations on Colorado River below Boulder Dam and on Bill Williams River); 

San Carlos Irrigation and Drainage District; Marlcopa County Municipal Water Conservation District No. 1; Glla Valley Irrigation District; and Imperial Irrigation 

District.

Colorado: Office of the State Engineer, M. C. Hinderlider, and the State V/ater 

Conservation Board, C. H. Stone, director.

Interstate Stream Commission, T. M. McClure, secretary. 

Utah: Office of the State Engineer, E. H. Watson.

Wyoming: Office of the State Engineer, L. C. Bishop, and the State Planning and 

Water Conservation Board, Gov. L. C. Hunt, president.

Financial assistance was furnished by the Corps of Engineers, U. S. Array, for the operation of 10 gaging stations in Arizona and 1 in New Mexico and for the obtaining of additional high-water discharge measurements at gaging stations in Utah.

Financial assistance was also furnished by the Bureau of Reclamation, United States 

Department of the Interior, and the Defense Plant Corporation of the United States Department of Commerce.

Assistance in collecting the records was rendered by the following organizations: 

Colorado: Denver Board of V/ater Commissioners, Bureau of Reclamation of the 

United States Department of the Interior, and Uncompahgre Valley V/ater Users' 

Association.

Utah: National Park Service and Bureau of Reclamation, both of the United States 

Department of the Interior, Moon Lake Water Users' Association, and Utah Power & 

Light Co.

DIVISION OF WORK

The stream-gaging work was conducted by the water resources branch of the Geological 

Survey, Glenn L. Parker, chief hydraulic engineer, Carl G. Paulsen, assistant chief 

hydraulic engineer, and Rudolph G, Kasel, chief of the division of surface water (until 

June 14, 1945). The data for the stations in the several States were collected and 

prepared for publication under the supervision of district engineers as follows: In 

Arizona, in California, in Nevada, and for Puerco River at Gallup, N. Mex., and Gila River 

below Blue Creek, near Virden, N. Mex., J. H. Gardiner; in Colorado (except for Los Pinos 

River at Ignacio) and for Green River near Linwood, Utah, Sheep Creek near Manila, Utah, 

White River near Watson, Utah, and Twomile Creek near La Sal, Utah, Robert Follansbee, the 

work being done in collaboration with M. C. Hinderlider, State engineer, and L. T. Burgess, 

State chief hydrographer; in New Mexico (except for the two stations named above) and for 

Los Pinos River at Ignacio, Colo., Berkeley Johnson; in Utah (except for the four stations 

named above), M. T. Wilson; In Wyoming, Robert Follansbee.

The records were reviewed and the manuscript prepared for publication under the direction of B. J. Peterson,hydraulic engineer in charge, and F. J. Flynn, associate engineer, section of reports.

T. 40 N., R. 7 E., at head of Marble Gorge at Lees Ferry, Just upstream from Parla 

River, 28 miles downstream from Utah-Arizona State line, 61.5 miles upstream fron 

Little Colorado River, and 79 miles downstream from San Juan River. Datum of gage 

Is 3,106.16 f.eet above mean sea level, datum of 1929.

Drainage area.- 107,900 square miles.

Records available.- June 1921 to September 1945. Also calendar year estimates 1895-1910, 

ana nontniy estimates January 1911 to May 1921, published In Water-supply Paper 918.

Average discharge.- 24 years (1921-45), 17,520 second-feet.

Extremes.- Maximum discharge during year, 64,400 second-feet May 17 (gage height, 14.90 

reet); minimum, 3,790 second-feet Dec. 18, 19 (gage height, 6.40 feet).

1921-45: Maximum discharge, 220,000 second-feet June 18, 1921 (gage height, 26.5 

feet, from floodmarks), from rating curve extended above 120,000 second-feet on basis 

of rating curve for station near Grand Canyon; minimum, 750 second-feet Dec. 27, 1924 

(gage height, 4.2 feet).

Maximum discharge known, about 300,000 second-feet July 7, 1884 (gage height, 31.5 

feet, present site and datum, from floodmark at mouth of Paria River), from rating 

curve extended above 120,000 second-feet, verified at 220,000 second-feet by comparison 

with rating curve for station near Grand Canyon.

Remarks.- Records excellent. Diversions above station for irrigation. Records of water 

analyses and sediment loads for water year 1945 are given In V/ater-Supply Paper 1030.

Location.- Water-stage recorder, lat. 34 041'15n , long. 114°27'45", In NWi sec. 13,

 T. lb N., R. 21 W. 01la and Salt River meridian, in Mohave Canyon, 3 miles downstream 

from Topock and 39.5 miles upstream fron Parker Dam. Datum of gage Is 423.02 feet 

above mean sea level, datum of 1929. Auxiliary water-stage recorder at highway bridge 

at Topock, 2.7 miles upstream, used in determining fall.

Drainage area.- 172,300 square miles.

Records -available.- January 1917 to September 1945.

Average discharge.- 17 years (1917-34), 20,260 second-feet (unregulated); 11 years

 (19o4-4b), 13,^50 second-feet (regulated, but not adjusted for storage In Lake Mead).

Extremes.- Maximum daily discharge during year, 22,300 second-feet Mar. 24; maximum ele-

 vatlon, 451.85 feet July 2; minimum daily discharge, 10,500 second-feet Sept. 6; 

minimum elevation, 448.36 feet Aug. 1.

1917-34 (unregulated): Maximum discharge probably exceeded 200,000 second-feet 

June 2£, 1921; minimum, 1,480 seoorid-feet Aug. 17, 1934.

1934-45 (regulated): Maximum discharge, 35,700 second-feet Jan. 29, 1942; maximum 

elevation, 452.37 feet July 19, 1943; minimum, 375 second-feet Feb. 14, 1935; minimum 

daily, 422 second-feet Feb. 14, 1935.

Discharge of about 300,000 second-feet (based on determination at Lees Ferry gaging 

station) occurred about July 10, 1884. Discharge in excess of 400,000 second-feet 

(estimated) probably occurred within the period 1057-68 and most likely in 1862.

Remarks.- Records excellent. Discharge computed by using fall as determined by auxiliary

 water-stage recorder as a factor. Diversions above station for irrigation and Industrial uses. Flow regulated by Boulder Dam; no regulation between Boulder Dam and 

this station. Elevations given are to datum of 1929.

z N., R. 27 E. San Bernardino meridian, 4.1 miles downstream from Parker Dam, 10.4

miles upstream from Headgate Rock Dam, and 11 miles northeast of Parker, Ariz. Datum

of gage is 346.16 feet above mean sea level, datum of 1929. 

Drainage area.- 178,800 square niles. 

Kecoras available.- February to September 1934 (gage heights and fragmentary discharge

records;, uc-cooer 1934 to September 1945. Records of diversion by Colorado River

aqueduct, January 1939 to September 1945. 

Average discharge.- 11 years (1934-45), 13,190 second-feet (not adjusted for storage);

li years (J.934-45-), 13,270 second-feet (adjusted to include storage in Havaau Lake,

but not in Lake Mead). 

Extremes (regulated).- Maximum discharge during year, 24,400 second-feet Jan. 28 (gage

neignt, aS.iy reet); minimum daily, 8,830 second-feet Aug. 12.

1935-45: Maximum discharge, 42,400 second-feet Feb. 8, 1937; no flow at Parker

Dam parts of several days in 1942 when gates in dam were closed; minimum daily, 1,440

second-feet Feb. 15, 1935.

An unregulated discharge of probably less than 1,350 second-feet occurred Aug. 18,

1934 (lowest unregulated discharge since 1917 and probably since a much earlier date). 

Remarks.- Records excellent. Many diversions above station. Flow regulated by Boulder

ana Parker Dams (see pp. 22, 27). Diversion by Colorado River aqueduct, 1.8 miles

upstream from Parker Dam, is water pumped from Havasu Lake less water spilled from

Gene Reservoir and returned to Havasu Lake. No return surface flow from Gene and

Copper Basin Reservoirs during year. Some water returned to river both above and

below station by percolation from both reservoirs.

for use in Arizona. Water was first diverted by All-American Canal in October 1938 and 

by Gila Gravity min Canal in August 1943.

No records of flow of Colorado River have been collected at site of dam either before 

or after its construction. The discharge figures published herewith are the sum of 

monthly records of discharge obtained at gaging stations on Colorado River at Yuma, AllAmerican Canal near Imperial Dam, and Gila Gravity Ifeln Canal at Imperial Dam, plus 

records of diversions by Yuraa Canal and North Gila Valley Canal at Laguna Dam furnished 

by Bureau of Reclamation. The Gila River did not discharge any water during the year.

38 DIVERSIONS AND RETURN FLOWS AT AND BELOW IMPERIAL DAM

Yuma Main Canal at siphon-drop power plant, near Yuma, Arlz.

Location.- Water-stage recorders on forebay and tallrace at power plant, lat. 32°46'35", 

 long. 114°38'05", In SEiSEi sec. 10, T. 16 S., R. 22 E. San Bernardino meridian, 500 

feet fron turnout In All-Amerlcan Canal to Yuma Main Canal, 34 miles north of Yuma, 

and 144 miles downstream from intake of All-Amerlcan Canal at Imperial Dam. Datum of 

each gage Is at mean sea level, Yuma project datum, or 0.70 foot above mean sea level, 

datum of 1929 (subject to undetermined changes caused by earthquake of May 18, 1940). 

Prior to Mar. 2, 1945, forebay gage was a staff gage at sane site and datum.

Records available.- October 1938 to September 1945.

Extremes.- Maximum dally discharge during year, 1,980 second-feet on many days; no flow

1938-45: Maximum dally discharge, 2,040 second-feet Nov. 11, 1943; no flow 

Sept. 5-11, 1939, Jan. 4-8, 1945.

Remarks.- Records excellent. Dally discharge determined fron flow through turbines, 

computed fron reltalon between discharge, head, and gate openings, to which Is added 

snail discharge passed around power plant through waste gates. By-passed discharge 

computed on basis of gage readings at forebay, and record of v/aste gate openings, 

by orifice formula. Rating of turbines checked by current-meter measurements. 

Records show water available for power development at siphon-drop power plant and 

for Irrigation on Valley division of Yuma project. Water for Yuma Main Canal was 

diverted from All-Amerlcan Canal Oct. 1 to Feb. 12 and June 27 to Sept. 30, from 

Colorado River at Laguna Dam Feb. 13 to Apr. 11 and June 2-16; and part from each 

source Apr. 12 to June 1 and June 17-26. Most of water not needed for Irrigation 

Is returned to Colorado River through Yuma Main Canal wasteway, 3i miles 

downstream.

Cooperation.- Record of gage heights on forebay prior to liar. 2 and of turbine gate 

openings furnished by Bureau of Reclamation.

Discharge, in second-feet, water year October 1944 to September 1945

Yuma Main Canal below Colorado River siphon, at Yuma, Arlz.

Location.- Two gages determine head on Colorado River siphon. At intake, water-stage

 recorder, lat. 32°43'50", long. 114°37'10", in SWiSEi sec. 26, T. 16 S., R. 22 E. San 

Bernardlno meridian, on California side of river, 1,645 feet downstream from center of 

Yuma Main Canal wasteway gates, and 34 miles downstream from siphon-drop power plant. 

At outlet, water-stage recorder in NWiNEi sec. 35, T. 16 S., R. 22 E. San Bernardlno 

meridian, on Arizona side of river. Both gages are a quarter of a mile downstream 

from highway bridge over Colorado River at Yuma. Datum of each gage is 100.03 feet 

above mean sea level, Yuma project datum, or 100.57 feet, datum of 1920.

Records available.- October 1938 to September 1945.

Extremes.- Maximum daily discharge during year, 716 second-feet Sept. 19 (head, 1.38 

feet); no flow Jan. 5-8.

1938-45: Maximum discharge, 784 second-feet Apr. 11, 1939 (head, 1.65 feet); no 

flow during short periods in most years.

Remarks.- Records excellent except those below 150 second-feet, which are fair. Dally 

discharge computed from relation between discharge and head on siphon, which is the 

difference between stages at intake and outlet gages. Records show quantity of water 

delivered through Colorado River siphon for irrigation on Valley Division of Yuma 

Project and for supplementary municipal supply for city of Yuma. First diversion for 

supplementary municipal supply was made June 15, 1945. Records of water analyses for 

the water year 1945 are given in Water-supply Paper 1030.

Cooperation.- Record of diversion for supplementary municipal supply for city of Yuna 

collected by Arizona Edison Company.

Discharge, in second-feet, water year October 1944 to September 1945

DIVEHSIONS AND RETURN FLOWS AT AND BELOW IMPERIAL DAM 41

Pilot Knob wasteway near Pilot Knob, Calif.

Location.- Water-stage recorder on All-Amerlcan Canal 550 feet upstream from waste gates 

at lat. 32 044'1511 , long. 114°42 f 55", In NW^SWi sec. 25, T. 16 S., R. 21 E. San Bernardlno meridian, 2 miles east of summit of Pilot Knob, 6 miles west of-Yuma, and 20.8 

miles downstream from Intake of All-Amerlcan Canal at Imperial Dam. Datum of gage Is 

at mean sea level, datum of 1929.

Records available.- July 1944 to September 1945. Also computations of discharge for 

periods When there was flow prior to July 1944 (Feb. 5 to Mar. 13, Sept. 24-28, 1939, 

and Apr. 16, 1941).

Extremes.- Maximum dally discharge during year, 3,520 second-feet Sept. 7; no flow during 

year prior to June 2.

1939-45: Maximum dally discharge, 4,460 second-feet July 24, 1944; no flow during 

long periods.

Remarks.- Records good. Dally discharge computed from head and openings of waste gates 

ana checked by current-meter measurements In All-Amerlcan Canal above and below 

wasteway. Record shows water diverted from All-Amerlcan Canal to Alamo Canal for use 

In Mexico or for return to Colorado River through Rockwood gate. This record Is not 

equivalent to that for Alamo Canal at Andrade (see p. 43).

42 DIVERSIONS' AND RETURN FLOWS AT AND BELOW IMPERIAL DAM

Diversions at Laguna Dam, Ariz.-Calif.

Location.- Laguna Dam, lat. 32°49'30", long. 114°29'40", is a diversion dam across

Colorado River, 5 miles downstream from Imperia.l Dam, 9 miles upstream from Gila River, 

and 10 miles northeast of Yuma, Ariz. Yuma Canal diverts water at California end of 

dam in SWiNEi sec. 25, T. 15 S., R. 23 E. San Bernardino meridian, and North Glla 

Valley Canal diverts water at Arizona end of dam in SWi sec. 14, T. 7 S., R. 22 U. 

Gila and Salt River meridian.

Records available.- Yuma Canal (formerly published as Yuma Main Canal): March 1910 to 

September 1945. North Gila Valley Canal: March 1935 to September 1945.

Remarks.- Yuma Canal normally furnishes most of water for Irrigation of Yuma project In 

California east of Yuma Main Canal. However, from February to June 1945, during period 

of repairs at Imperial Dam, it furnished most of water for entire Yuma project. Prior 

to Aug. 4, 1941, before Yuma project obtained water from Imperial Dam, this canal was 

part of Yuma Main Canal. North Gila Valley Canal supplies water for Irrigation In 

Arizona north of Gila River, In the district known as North Gila Valley. Records for 

both canals show total diversions.

Cooperation.- Records furnished by Bureau of Reclamation.

DIVERSIONS AND RETURN FLOWS AT AND BELOW IMPERIAL DAM 43

Alamo Canal at Andrade, Calif.

-Location.- Staff gage, lat. 32 043'10", long. 114°43'30", in SWiSEi sec. 35 T. 16 S., 

R. 21 E. San Bernardlno meridian, at Andrade, 200 feet upstream from international 

boundary, 800 feet downstream from Hanlon heading, and li miles downstream from 

Rocltwood gate.

Records available.- January 1908 to September 1945. Records prior to 1936 published 

in water-supply Paper 918 as Imperial Canal at Hanlon heading, at Andrade.

Remarks.- Figures given herein are those of total flow and are computed from daily 

current-meter measurements and staff-gage readings.

Canal diverts water from right side of Colorado River in SEiSWi sec. 25, T. 16 S., 

R. 21 E. San Bernardino meridian, at Rockwood gate, 24i miles downstream from Imperial Dam, and at times receives water from Pilot Knob wasteway (see p. 41). This 

year all water from June 3 to Sept. 30 was received from Pilot Knob wasteway. Water 

is used for irrigation of lands in Imperial Valley in Mexico.

Hanlon heading is a separate set of gates on Alamo Canal 1 mile below Pilot Knob 

wasteway used to control flow of water down canal. The gates may be operated to 

allow Pilot Knob wasteway water either to pass down canal or to be returned to 

Colorado River.

Cooperation.- Records furnished by Imperial Irrigation District; 4 discharge measurements 

maae ana records reviewed by Geological Survey.

44 DIVERSIONS AND RETURN FLOWS AT AND BELOW IMPERIAL DAM

Return surface flows from Yuma project, Ariz.-Calif.

Yuma project of the Bureau of Reclamation lies on both sides of Colorado River in the 

vicinity of Yuma.

Most of the water for the project in California is diverted at Laguna Dam to the Yuma 

Canal. The remainder is supplied by the Walapai Canal, which diverts from the forebay of 

the siphon-drop power plant, and by several small canals from the Yuma Main Canal between 

the power plant and the Yuma Main Canal wasteway. Waste and drainage water from the 

Reservation Division is collected by the California Drainage Canal and is returned to the 

Colorado River at the mouth of the Yuma Main Canal wasteway, but the flow is not included 

in the records for the wasteway.

Water for the project in Arizona is supplied from the Yuma Main Canal. After passing 

through the siphon-drop power plant and returning some water not needed to the Colorado 

River through the Yuma Main Canal wasteway, the Yuma Main Canal crosses the Colorado 

River by means of a siphon and divides into the East and West Main Canals. East Main 

Canal extends to the Arizona-Sonora boundary and discharges waste water across the 

boundary. Waste water from the West Main Canal is returned to Colorado River by Cooper, 

Eleven-Mile, and Twenty-one Mile wasteways which enter Colorado River 2^, 5i, and 15i 

miles, respectively, by airline downstream from Rockwood gate. Drainage water on the 

Valley Division is collected by the Main drain which discharges across the ArizonaSonora boundary by pumping.

In addition to the above during the 1944-45 water year the North Gila Valley project 

in Arizona returned 4,160 acre-feet through the North Gila Valley drain to the Colorado 

River in NE-J-NWi sec. 9, T. 8 S., R. 22 W., 5 miles downstream from Laguna Dam. This 

drainage canal was extended and enlarged during 1944 and no records are available prior 

to this year.

Monthly records of return flows from the Yuma project, and 46 discharge measurements 

which were the basis for the computation of the record for the North Gila Valley prpject 

drain, were furnished by Bureau of Reclamation. Records available October 1938 to 

September 1945.

from rating curve extended above 320 second-feet; no flow during some periods In 

nearly every year.

Remarks.- Records excellent above 16 second-feet and good below except those for periods 

or ice effect or no gage-height record, which are poor. No diversion above station.

Flow increased above station by diversion from Clear Fork East Muddy Creek 

(Gunnison River Basin) through Clear Fork ditch and by diversion from Thompson Creek 

(Roaring Fork Basin) through Thompson Creek feeder ditch. No diversion records 

during 1945.

254 SAN JUAN RIVER BASIN

San Juan River at Ship Rock, N. Mex.

Location.- Water-stage recorder, lat. 36 047'35", long. 108°43'55", in SWi sec. 22, T. 30 

N., R. 18 W., 3 miles northwest of Ship Rock and 6 miles downstream from Chaco River. 

Datum of gage is 4,848.6 feet above mean sea level (from river-profile survey).

Drainage area.- 12,800 square miles.

Records available.- January to October 1911, October 1930 to September 1931, and October 

1932 to September 1945 in reports of Geological Survey. January to October 1911 and 

November 1915 to December 1931 in reports of State engineer.

Average discharge.- 25 years (1916-20, 1921-25, 1927-31, 1932-45), 2,863 second-feet.

Extremes.- Maximum discharge during year, 8,920 second-feet May 5 (gage height, 6.51 

feet); minimum daily, 285 second-feet Sept. 12, 13.

1930-31, 1932-45: Maximum discharge, 44,200 second-feet Sept. 28, 1935, from rating 

curve extended above 20,000 second-feet by logarithmic plotting; maximum gage height, 

10.30 feet Oct. 14, 1941; minimum daily discharge, 8 second-feet Aug. 25, 26, 1939.

A stage of about 6.5 feet, site and datum then in use, occurred Aug. 11, 1929 

(discharge, about 80,000 second-feet). A greater discharge probably occurred Oct. 6, 

1911, when a stage of 22.0 feet on old gage (relation to present datum unknown) was 

recorded.

Remarks.- Records fair except those for period of no gage-height record, which are poor. 

Diversions above station for irrigation. Records of water analyses for water year 194f 

are given in Water-Supply Paper 1030.

GILA. RIVER BASIN 317

Diversions from Gila River in Duncan Valley, N. Mex.-Ariz.

Duncan Valley lies along Gila River in Hidalgo County, N. Hex., and Greenlee County, f 

Ariz. The part in New Mexico is also known as Virden Valley. The valley extends from a 

point about 8 miles east of State line to vicinity of Guthrie, Ariz. Ten canals, listed 

in the following table according to their position from east to west, and several pumps 

divert water from Gila River for irrigation in the valley. The first four^ canals listed 

divert in New Mexico, the others in Arizona. The Intake of Sunset Canal, 'at eastern end 

of valley, is 4 miles downstream from station on Gila River below Blue Creek, near Virden, 

N. Hex. The intake of York Canal at western end is 5 miles upstream from station on Gila 

River near Clifton, Ariz.

Records of daily and monthly diversions are available for Sunset and Hoddle Canals for 

1914-15 and 1922-31; for Valley and Colmenero Canals for 1914-15 and 1923-31; and for 

Duncan Canal for 1923-28. Di-scharge measurements are" available for York CanaJ for 1914-15 

and 1923-31.

Records of diversion since January 1936, except for Sunset, Moddle, and Shriver Canals 

for 1939-45, have been furnished by the Gila Water Commissioner, appointed by U. S. 

District Court for Arizona. Water-stage recorders and either rectangular sharp-crested 

weirs or Parshall flumes were used to obtain records on canals, and rated pumps used to 

obtain records of pumped water. See pp. 333-338 for records of Sunset, Moddle, and 

Shriver Canals for 1945.

The following tabulations of annual diversions by each canal and combined monthly diversions by canals as a group have been compiled by Gila Water Commissioner and Geological Survey.

GILA RIVER BASIN ' 329 

Gila River at Ashurst-Hayden Dam, near Florence, Ariz.

Location.- V/ater-stage recorder, lat. 33°06°00", long. 111°14 1 50", iri SWiNWi sec. 8, T. 

* s., K. 11 E., at Ashurst-Hayden Dam, 10.miles northeast of Florence. Permanent crest 

of dam is 1,562.6 feet above mean sea level, datum of 1929. Crest height varied between 

1.00 and 1.34 feet during year by use of flashboards. Florence-Casa Grande Canal 

diverts at left end of dam for irrigation of lands under San Carlos Project.

Drainage area.- 18,300 square miles.

Records available.- July 1923 to September 1945 (head on crest of dam only). Records of 

aiversions TO Florence-Casa Grande Canal available January 1928 to September 1945.

Extremes.- mximum head on dam during year, 2.1 feet Aug. 10; no flow over dam during 

greater part of year.

1923-45: Maximum head on dam, 8.0 feet Sept. 28, 1926; no flow over dam during 

greater part of each year.

Remarks.- Records show daily mean head on dam and monthly diversions to Florence-Casa 

aranae Canal. Mean head is often not representative of flow passing dam because of 

extensive sluicing. Diversion records are those at eanal gaging station (water-stage 

recorder and Parshall flume) 2.6 miles downstream at China Wash adjusted for intervening 

sluicing and pumping (but not natural losses), to'show water available at dam, except 

for water passed over dam or sluiced through dam during times of flood runoff. 'Many 

diversions above station for irrigation. Flow regulated by Coolidge Dam except for 

periods of tributary inflow below that dam. San Pedro River contributes major portion 

of unregulated inflow.

Cooperation.- Records collected and prepared in cooperation with Office of Indian Affairs.

Daily mean head, in feet, water year October 1944 to September 1945

Eagle Creek above pumping plant> near Morenci, Ariz.

Location.- Water-stage recorder, Parshall flume and weir, lat. 33004'00", long.

109"26'45", in-sec. 22, T. 4 S., R. 28 E., 2i miles upstream from Phelps Dodge Corporation pumping plant,,5 miles west of Morenci, and 13.miles upstream from mouth.

Drainage area.- 613 square miles.

Records available.- April 1944 to September 1945.

Extremes.- 1944: Maximum discharge during period April to September not determined,

occurred on Sept. 26 (stage, about 10 feet,from floodmarks); minimum, 3.7 second-feet 

June 24.

1944-45: Maximum discharge during water year, 433 second-feet Aug. 11 (gage height, 

4.18 feet); minimum, 5.1 second-feet Aug. 31 (affected by diversion from Black River).

A discharge of 13,000 second-feet (by slope-area method) occurred Feb. 10, 1932, at 

a stage of 11 feet above normal low water at suspension bridge 2f miles downstream; 

stage of the- flood of Sept. 26/1944 was about 2.5 feet lower at same site.

Remarks.- Records excellent except those prior to Apr. 1, 1945, whicli'are good, those for 

period of no gage-height record or those above 200 second-feet, which are poor. Diversions above station for irrigation of 500 acres, mostly above Willow Creek. Beginning 

Apr. 21, 1945, water from Black River was pumped almost continuously into'Eagle-Creek 

Basin, 53 miles upstream from this station (see records for Willow Creek diversion from 

Black River, near Morenci, p. 345). Diversions by pumping for mining, metallurgical 

treatment of ores, and domestic use in and near Morenci and Clifton are made from Eagle 

Creek, 2i miles below station, and from San Francisco River at and near Clifton. The 

monthly quantities diverted are -shown in the following tables. More than 96 percent of 

the pumpage was from Eagle Greek.

Cooperation.--Records of pumpage from Eagle Creek and San Francisco River prior to Mar. 1, 

1945, furnished by Phelps Dodge Corporation.

gage is 1,431.2 feet above mean sea level, datum of 1929.

Drainage area.- 1,460 square miles.

Records available.- November 1910 to September 1924 (published as Agua Fria River near 

 Gienaaie), octooer 1933 to September 1945.

Extremes.- Jfeximum discharge known, about 105,000 second-feet Nov. 27, 1919; no flow during 

spring and summer of several years.

Remarks.- Records poor. Figures given herein represent flow into Lake Pleasant. Discharge 

computed on basis of three factors as follows; 1. Change in contents of Lake Pleasant 

and in contents of small reservoir behind diversion dam li miles downstream from Lake 

Pleasant. 2. (a) Release from Lake Pleasant as measured by water-stage recorder and 

sharp-crested rectangular weir in canal 650 feet downstream from intake at diversion 

dam, rated and frequently checked by a Clausen-Pierce weir rule, and (b) spill from 

'Lake Pleasant as measured over diversion dam (none in water year 1944-45). 3. Effect 

of rainfall and evaporation on lake; evaporation assumed as 0.7 of that measured once 

daily in 3-foot-square buried land pan near left end of Lake Pleasant Dam. Effect of 

bank storage and bank release in Lake Pleasant is not taken into account. Diversions 

above Lake Pleasant for irrigation.

Cooperation.- Records collected and prepared in cooperation with mricopa County Municipal 

water conservation District No. 1.
