SURFACE WATER SUPPLY OF THE COLORADO RIVER BASIN, 1942

SCOPE OF WORK

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

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

water year ending September 30, 1942. The work was begun in 1888 in connection with 

special studies relating to irrigation. Measurements of the flow of streams and of the 

stage and contents of lakes and reservoirs have been made at about 9,400 gaging stations 

in the United States and also at many gaging stations in Alaska and Hawaii. In July 1942, 

4,970 gaging stations were being maintained by the Geological Survey and cooperating organizations. Miscellaneous discharge measurements were made 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 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 foot 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 the 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 the water 

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 quantityof water required to cover an acre to the deptn 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 the 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 used to designate a feature downstream from the gage that determines 

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

of the channel, or an artificial structure.

EXPLANATION OF DATA

The base data collected at gaging stations consist of records of stage, measurements of 

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

2 EXPLANATION OF DATA

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

direct readings on a nonrecordlng 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 on plate 1.

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

Included In the periods of Ice effect and the days during the winter period on which discharge measurements were made are Indicated In the table by symbols referring to footnotes 

or are given In a general note following the table.

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 dally 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 

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; the minimum discharge If there Is little or no regulation; the minimum dally discharge if there Is extensive regulation (also the minimum discharge if useful); 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 the times of their occurrence are given below the table of monthly discharge for some 

stations. This supplementary Information is generally omitted for stations having drainage areas of less than 10 square miles or more than 10,000 square miles or If the peak 

discharges usually exceed the corresponding mean discharges for the day by less than 10 

percent.

For stations equipped with nonrecording gages, the table of daily discharge gives 

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

of twice-daily readings. For flashy floods the .daily mean discharge is determined from 

gage-height graphs based on gage readings made once or twice dally or oftener, as stated 

in the station description. 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 daily mean gage height. For stations subject to such fluctuation the 

dally mean gage height may not indicate the true dally mean discharge, which must be obtained by averaging the discharge for parts of the 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.

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 daily discharge. The column headed 

"Maximum" gives the maximum daily discharge and not the momentary discharge when the 

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

given is the 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 reservoirs the data presented comprise a description of the station and a monthly summary table of stage and contents. For some reservoirs 

a table showing daily 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 moved 

ahead 1 hour, or to 3 a.m. This made February 9 a 23-hour day. Time prior to 2 a.m. 

February 9 as given herein refers to standard time; time after 2 a.m. February 9 refers 

to war time. To convert war time to standard time, subtract 1 hour.

Records of daily discharge prior to February 9, 1942, published herein have been 

computed on the basis of standard time. Records subsequent to that date have been computed
4 TIME BASIS

on the basis of war time. The discharge given for February 9 Is the mean for 23 hours. 

The mean discharge and runoff for the month of February have been computed from the total 

second-foot-days for the month without adjustment for the fact that February 9 was a 

23-hour day. The small error resulting from this procedure has been disregarded.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

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 dally records are accurate within 

5 percent; "good," within 10 percent; "fair," within 15 percent; and "poor," within 20 

or a higher percent. The records of monthly and yearly mean discharge and runoff are, in 

general, more accurate than the dally 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 "secondfeet 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 of reservoirs or for other 

changes Incident to use and control. Figures of second-feet per square mile and runoff 

in inches are also omitted if the drainage area includes large noncontributing areas or 

if the average annual rainfall over the drainage area is less than 20 inches.

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 dally 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 dats, grouped by years 

and drainage basins, are listed by number on page 7. The data for any particular 

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

station was maintained. For example, the date for 1910 to 1920 for any station in the 

area covered by part 3. are published in Water-Supply Papers 283, 303, 323, 353, 403, 433, 

453, 473, 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. 7), contains a summary of yearly discharge at gaging 

stations in the area covered by that report. Gaging stations at which 10 or more complete years of record have been collected are represented. These summaries are available 

also as separate reprints.

Drainage area.- 170,600 square miles.

Records available.- April 1931 to September 1942 (elevations only).

Extremes.- Maximum elevation during year, 473.11 feet Feb. 5; minimum, 469.78 feet Apr. 7. 

1931-42: Maximum elevation, that of Feb. 5, 1942; minimum, 466.53 feet Oct. 2, 1934.

Remarks.- Flow completely regulated by Boulder Dam. (See p. 21 .) Comparison of many 

simultaneous readings showed an average difference of 0.21 foot due to slope in water 

surface between gages of former and present sites.

Note.- Ho recording-gage record Oct.-16 to Nov. 5 and Dec. 16 to Jan. 6; record computed from 

graph based on one or two staff-gage readings daily and by comparison with unpublished record of 

gage heights at Topock highway bridge.

Time basis: Mountain standard time Oct. 1, 1941, to Jan. 8, 1942; Pacific standard time Jan. 9 

to 2 a.m. Feb. 9; Pacific war time 2 a.m. Feb. 9 to May 18; mountain war time May 19 to Sept.30. 

To convert war time to standard time, subtract 1 hour.
24 COLORADO RIVER MAIN STEI1

Colorado River near Topock, Arlz.

Location.- Water-stage recorder, lat. 34°41'15", long. 114°27'45", In NWi sec. 13, T. 15 

N., R. 21 W., Glla and Salt River meridian, In Mohave Canyon, 3 miles downstream from 

Topock, 40 miles upstream from Parker Dam, and 116 miles downstream from Boulder Darn. 

Datum of gage Is 423.02 feet above mean sea level, datum of 1989, and 423.08 feet 

above mean sea level, adjustment of 1912. 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.- February 1917 to September 1942.

Average discharge.- 16 years (1918-34), 20,210 second-feet (unregulated); 8 years (1934-42), 

16,560 second-feet (adjusted for storage In Lake Mead but not for evaporation losses).

Extremes.- Maximum discharge during year, 35,700 second-feet Jan. 29; maximum gage height, 

25.99 feet Dec. 17; minimum discharge, 7,950 second-feet Apr. 7; minimum gage height, 

17.86 feet Sept. 1.

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

June 22, 1921; minimum, 1,480 second-feet Aug. 17, 1934.

1935-42 (regulated): Maximum discharge, that of Jan. 29, 1942; 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 for Lees Ferry 

gaging station) occurred about July 10, 1884. Discharge in excess of 400,000 secondfeet (estimated) probably occurred within the period 1857-68 and most likely in the 

high years 1862 or 1867.

pemarks.- Records good. Discharge March 1 to June 30 computed by using fall as a factor. 

Diversions above station for irrigation. Discharge regulated at Boulder Dam; no regulation between Boulder Dam and this station. Elevations given in the following table 

are in agreement with datum of 1929.

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

gage Is 346.16 feet above mean sea level, datum of 1929, or 345.61 feet, adlustment 

of 1912.

Drainage area.- 178,800 square miles.

Kecords available.- February to December 1934 (gage heights and fragmentary discharge 

records), January 1935 to September 1942. Records of diversion to Colorado River 

aqueduct, January 1939 to September 1942.

Extremes (regulated).- Maximum discharge during year, 35,000 second-feet Dec. 12, 13;

maximum gage height, 27.78 feet Dec. 11; no flow at Parker Dam except for minor leakage 

when gates In dam were closed part of each day Feb. 27, and Sept. 8-1S; minimum daily, 

3,640 second-feet Feb. 27.

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

except for monor leakage when gates In dam were closed part of each day Feb. 27 and 

Sept. 8-12, 1942; minimum dally, 1,440 second-feet Feb. 15, 1935.

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

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

Remarks.- Records excellent. During the year 107 discharge measurements were made. 

Diversions above station for Irrigation. Flow regulated at Boulder and Parker Dams. 

(See pp. 21, 26 .) Diversion to Colorado River aqueduct 1.8 miles upstream from 

Parker Dam Is water pumped from Lake Havasu less water spilled from Gene Reservoir and 

returned to Lake Kavasu. ;,o return surface flow from Copper Basin Reservoir during 

year. Some water probably returned to river both above and below station by percolation from both reservoirs.

Location.- Water-stage recorder, lat. 32°43'45", long. 114°57'15", in IIWilEi sec. 35, T. 

16 S., R. 22 E., San Eernardino meridian, 1,800 feet downstream from highway bridge 

at Yuma, 5 miles downstream from Gila River, 19 miles downstream from Imperial Dam, 

and 7 and 29 miles upstream from international boundaries of California and Arizona 

respectively, with Mexico. Datum of gage is 102.86 feet, datum of 1912 and 1929, and 

102.32 feet (Yuma project datum) above mean sea level (revised as a result of changes 

caused by earthquake of May 18, 1940).

Drainage area.- 242,900 square niles (including all closed basins entirely within the 

drainage boundary).

Records available.- January 1878 to December 1901 (gage heights only), January 1902 to 

September 1942.

Extremes.- Maximum discharge during year, 31,800 second-feet Feb. 7; maximum gage height, 

SI.57 feet Dec. 16; minimum discharge, 3,760 second-feet Mar. 1, caused by regulation 

at Parker Dam; minimum gage height, 11.85 feet Sept. 10.

1902-42: Maximum discharge, 250,000 second-feet Jan. 22, 1916 (gage height, 34.0 

feet); minimum daily, 18 second-feet Aug. 25-27, 1934, caused by diversion of river 

flow at Laguna Dam; minimum gage height, that of Sept. 10, 1942.

Remarks.- Records excellent. Many diversions for irrigation from Colorado River and 

tributaries. Principal diversions below Parker Dam are Colorado River Indian Reservation Canal (p. 281), Palo Verde Canal (p. 281), All-American Canal (p. 31), and 

the two canals at Laguna Dam (combined diversion in -water year 1942, 103,000 acrefeet) . Flow of Colorado River regulated by Boulder, Parker, Headgate Rock, and 

Imperial Dams. No regulation on Gila River below Gillespie Dam. Water was by-passed 

around Yuma river station and returned to river half a mile downstream through Yuma 

Main Canal wasteway (p. 35); no water by-passed and returned through Pilot Knob wasteway this year. During the year, 195 river discharge measurements were made.

Discharge, in second-feet, water year October 1941 to September 1942

All-American Canal above Pilot Knob wasteway, Calif.

Location.- Water-stage recorder, lat. 32°45', long. 114°42', In SEi sec. 24, T. 16 S.,

 R. 21 E., San Bernardino meridian, at bridge on U. S. Highway 80, 1 mile upstream 

from Pilot Knob wasteway, 54 miles northwest of Yuma, and 19* miles downstream from 

intake at Imperial Dam. Datum of gage is 148.52 feet above mean sea level, datum of 

1929 (revised as a result of changes caused by earthquake of May 18, 1940). Auxiliary water-stage recorder, in NEiNWi sec. 15, T. 16 S., R. 22 E., on wash overshoot 

structure 4.4 miles upstream.

Records available.- October 1938 to September 1942.

Extremes.- Maximum discharge during year, 4,670 second-feet Apr. 3; maximum gage height, 

11.85 feet, 11:30 a.m. Apr. 3; no flow part of Oct. 12.

1938-42: Maximum discharge and gage height, that of Apr. 3, 1942; no flow on 

several days since continuous operation began Sept. 18, 1940.

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

 water-stage recorder as a factor. Flow past this station shows water available to 

Imperial Valley except for canal losses and waste at Pilot Knob wasteway. No flow 

through Pilot Knob wasteway during year except negligible leakage. Beginning March 

1942, Imperial Valley in California was supplied entirely by the All-American Canal.

Discharge, in second feet, water year October 1941 to September 1942

COLORADO RIVER MAIN STEM 33

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

Location.- Two gages consisting of staff gage on forebay and water-stage recorder on tallrace at power plant, lat. 32°46'30", long. 114°38'00 , In SEiSEi sec. 10, T. 16 S., R. 

R. 22 E., San Bernardino meridian, SCO feet downstream from turnout In Ail-American 

Canal to Yuma Main Canal, 3-J miles north of Yuma, 10-J miles downstream from intake of 

Yuma Main Canal at Laguna Dan, and 14$ miles downstream from intake of Ail-American 

Canal at Imperial Dan. 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 correction due to 

undetermined changes caused by earthquake of May 18, 1940).

Records available.- October 1938 to September 1942.

Extremes.- Maximum dally discharge during year, 1,980 second-feet Sept. 29; minimum dally, 

1,790 second-feet Oct. 15, Nov. 1.

1938-42: Maximum daily discharge, that of Sept. 29, 1942; no flow Sept. 5-11, 1939.

Remarks.- Records excellent. Dally discharge determined from flow through turbines, computed from relation between discharge, head, and gate openings, to which is added small 

discharge passed around power plant through waste gates. Bypassed discharge computed on 

basis of gage readings at forebay, and record of waste gate openings, by orifice formutla. Rating of turbines checked by current-meter measurements. Records show quantity 

of water available for irrigation on Valley division of Yuma project. Water not 

needed for Irrigation is returned to the river through Yuma Main Canal wasteway 3 

miles downstream. The All-American Canal first diverted water to the Yuma Main Canal 

above the power plant on Oct. 8, 1340, and furnished all the water at this point after 

Aug. 4, 1941.

Cooperation.- Record of gage heights at forebay and of turbine gate openings furnished by 

Bureau of Reclamation.

present site), in reports of Geological Survey. April.1917 to September 1930 and 

January 1934 to September 1942 in reports of State engineer.

Average discharge (river and power canal).- 22 years (1917-30, 1933-42), 3,023 secondfeet.

Extremes (combined flow of river and power canal).- Maximum discharge, 21,900 secondfeet May 27; minimum dally, 630 second-feet Aug. 31.

1917-30, 1933-42: Maximum discharge observed, 35,700 second-feet May 23, 1920 

(gage height, 14.95 feet), from rating curve extended above 21,400 second-feet; 

minimum daily, 106 second-feet July 20, 1934.

Remarks.- Records excellent except those for period Jan. 3 to Mar. 13, which are good. 

Diversions above station for irrigation. Combined flow of river and Redlands power 

canal minus about 40 second-feet diverted during Irrigation season represents entire 

flow that enters Colorado River from Qunnison River Basin. Discharge tables include 

flow of power canal.

a No gage-height record; discharge computed on basis of one discharge measurement and record for 

Little Snake River near Dixon, Wyo.

Note.- Stage-discharge relation affected by ice Mar. 27 to Apr. 5. No gage-height record Nov. 12 

to Mar. 26 (stage-discharge relation affected by ice during most of period); discharge computed on 

basis of three discharge measurements and weather records.

Time basis: Mountain standard time prior to 2 a.m., Feb. 97 1942; mountain war time thereafter. 

To convert war time to standard time, subtract 1 hour.

1939-40: Maximum discharge during water year, 202 second-feet May 16 (gage height, 

3.10 feet); minimum, 7 second-feet Jan. 2, but may have been less during period of Ice 

effect.

1940-41: Maximum discharge during water year, 360 second-feet Aug. 17 (gage height, 

4.50 feet), from rating curve extended 250 second-feet by logarithmic plotting; minimum 

not determined (occurred during period of Ice effect).

1941-42: Maximum discharge during water year, 293 second-feet May 30 (gage height, 

3.89 feet); minimum not determined (occurred during period of ice effect).

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

Two small diversions above station for Irrigation. Waters from Oaks Park Reservoir on 

headwaters (capacity, 6,250 acre-feet) are diverted to Ashley Creek Basin, above station for Irrigation.

Cooperation.- Gage-height record and two discharge measurements Oct. 1 to Dec. 18, 1941 

furnished by Bureau of Reclamation. Records for March 1939 to September 1941 collected 

and computed by Bureau of Reclamation and reviewed by Geological Survey.

September 1942.

Average discharge.- 14 years (1925-26, 1929-42), 168 second-feet.

Extremes.- Maximum discharge during year, 1,490 second-feet June 7 (gage height, 3.58 

feet); minimum recorded, 43 second-feet Mar. 27, but may have been less during period 

of ice effect.

1929-42: Maximum discharge, 2,240 second-feet June 5, 1938 (gage height, 3.33 

feet, site and datum then in use), from rating curve extended above 1,300 second-feet; 

r.inimum recorded, 32 second-feet Mar. 10, 1941, but may have been less during period 

of ice effect.

Maximum discharge known, more than 3,000 second-feet June 9, 1922 (not determined 

more exactly because of unstable channel conditions).

Remarks.- Records good except those for periods of no gage-height record or ice effect, 

which are fair. Water which is diverted from Pole Creek and used at Uinta Power & 

Light Co.'s plant enters river 500 feet above station. Summer flow slightly regulated

Location.- Staff gage, lat. 39°48', long. 108°06', In N£ sec. 18, T. 3 S., R. 95 W., 

Just downstream from Story Gulch and 9 miles northwest of Rio Blanco. Altitude of 

gage, 6,950 feet (by barometer). A staff gage at different datum was destroyed by 

flood Apr. 14, 1942.

Drainage area.- 153 square miles.

Records available.- March 1941 to September 1942 (no winter records 1942).

Extremes.- Maximum discharge observed during year, 430 second-feet Apr. 13 (gage height, 

4.80 feet, datum then In use), from rating curve extended above 45 second-feet, but 

probably higher during period of no gage-height record; minimum observed, 2.2 secondfeet Mar. 15, 16 (gage height, 0.46 foot, datum then in use), probably less during

Maximum contents known, about 56,500 acre-feet at time first failure occurred May 

21, 1928 (gage height, about 7,607.2 feet).

Remarks.- Reservoir Is formed by earth and rock-fill, rock-faced dam. Storage began In 

May 1926. Original capacity, about 61,000 acre-feet. Due to several partial failures capacity Is now limited to 30,000 acre-feet between gage heights 7,571.0 feet 

(bottom of outlet tunnel) and about 7,595.7 feet (top of 5-foot flashboard control 

on spillway). Dead storage negligible. Gage read to half-tenths dally, usually 

about 9 a.m. Contents given herein are c&mputed from gage heights at that time; 

all available for release. Water Is used for Irrigation In the vicinity of Price.

Drainage area.- 776 square miles.

Records available.- May 1909 to December 1912 (published as Fremont River near Thurber) 

and October 1937 to September 1942.

Extremes.- Maximum daily discharge during year, 1,010 second-feet Apr. 5, 6; maximum discharge, 1,200 second-feet about Apr. 5 (gage height, 5.8 feet, from floodmarks), from 

rating curve extended above 700 second-feet; minimum daily observed, 53 second-feet 

July 13, 14.

1909-12, 1937-42: Maximum daily discharge observed, that of Apr. 5, 6, 1942; maximum discharge observed, that of Apr. 5, 1942; minimum daily observed, 18 second-feet 

June 2, 4, 13-15, 17, 18, 1912.

Remarks.- Records poor. Records include flow of Torrey Canal and Mill ditch and represent 

flow of Fremont River above these diversions. Discharge computed by combining flow in 

canals with that in river below canals. Gages read once daily. Several diversions 

above station for irrigation. Flow affected by Fish Lake and Johnson and Forsythe 

Reservoirs.

Diversion for Colorado River Indian Reservation, near Parker, Arlz.

Location.- Diversion for Colorado River Indian Reservation is made at the Arizona end of 

Headgate Rock Dam, which is at lat. 34°10'05", long. 114°16'30 n , in NEi sec. 31, T. 

10 N., R. 19 W., Glla and Salt River meridian, on Colorado River Indian Reservation, 

14 miles northeast of Parker, and 14i miles downstream from Parker Dam. The diversion 

is measured by means of a rated canal gate below wasteway, at crossing of Arizona 

Highway 72, ll miles downstream from intake. Prior to June 28, the diversion was made 

at a pump house on left bank of Colorado River in SEi sec. 2, T. 9 N., R. 20 W., 1 

mile southwest of Parker.

Records available.- January 1915 to December 1938 (calendar year discharge), January 1937 

to September 1942 (monthly discharge).

Remarks.- Figures given herein show water available to the project. Discharge prior to 

June 28 computed from records of pump operation; discharge beginning June 28 computed 

on basis of head gate openings In canal below wasteway; both ratings checked occasionally by current-meter measurements. Water is used for irrigation of lands on the 

Colorado River Indian Reservation on east side of Colorado River between Parker and 

Ehrenberg. During the period of gravity diversion, July to September, 3,200 acre-feet 

of water was wasted into natural sloughs at the lower end of the project but was not 

in sufficient quantity to reach the Colorado River as surface flow.

Cooperation.- Records furnished by Office of Indian Affairs.

GILA RIVER BASIN 

Diversions from Glla River In Duncan Valley, N. Mex.-Arlz.

287

Duncan Valley lies along Glla River In Hidalgo County, N. Hex., and Greenlee County, 

Arlz. The part In New Mexico Is also known as Vlrden Valley. The valley extends from 

a point about 8 miles east of the State line to the vicinity of Guthrle, Arlz. Ten 

canals, listed In the following table according to their position from east to west, and 

five pumps divert water from Glla River for Irrigation In the valley. The first four 

canals listed divert In New Mexico, the others In Arizona. The Intake of the Sunset 

Canal, at the eastern end of the valley, is 4 miles downstream from the station on Glla 

River below Blue Creek, near Vlrden, N. Hex. The Intake of the York Canal at the western 

end Is about 5 miles upstream from the station on Glla River near Clifton, Arlz.

Records of dally and monthly diversions are available for Sunset and Moddle 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. Discharge measurements are available for York Canal for 

1914-15 and 1923-31.

Records of dally diversions since January 1936, except for Sunset, Moddle, and Shrlver 

Canals for 1939-42, have been collected and furnished by the Glla Water Commissioner 

appointed by the United States District Court for Arizona. Water-stage recorders and 

rectangular sharp-crested weirs were used by the Water Commissioner to obtain records on 

the canals and rated pumps were used to obtain records of pumped water. See pp. 

for records of Sunset, Moddle, and Shrlver Canals for 1942.

The following tabulations of the annual diversions by each canal and the combined 

monthly diversions by the canals as a group have been compiled by the Geological Survey.

Diversions from Gila River in Safford Valley, Ariz.

Safford Valley lies along Gila River in Graham County, Arlz., extending from the 

vicmity of Bonlta Creek on the east to San Carlos Indian Reservation on the west. 

Twelve canals, listed in the following table In downstream order, and one pump divert 

water from Gila River for irrigation In the valley. Intake of Brown Canal, at the upper 

end of the valley, is about three-quarters of a mile upstream from the station on Gila 

River near Solomonsville. Intake of Colvin-Jones Canal, at the lower end, is about 20 

miles upstream from station on Gila River near Calva.

Records of monthly diversion for all the canals except Fourness, Fort Thomas, and 

Colvin-Jones are available for 1914-15; records of dally and monthly diversions for all 

the canals except Colvin-Jones are available for 1920-31; records for Brown Canal are

records for 1914-15 and 1920-31). Records of monthly diversions for all canals are 

available for 1936-42.

Records of daily diversions since January 1936 have been collected by the Gila Water 

Commissioner, appointed by United States District Court for Arizona. Water-stage 

recorders with Parshall flumes or weirs were used by the water commissioner to obtain 

records of diversion by the canals, and rated pump was used to obtain record of pumped 

water. See record of Gila River at Safford for flow of Gila River between intakes of 

Graham and Smlthvllle Canals.

The following tabulations of annual diversion by each canal and combined monthly 

diversion by the canals as a group have been compiled and furnished by r^la Water 

Commissioner.

GILA RIVER BASIN 299

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

Location.- Water-stage recorder, lat. 33°06', long. 111°15', In NWt sec. 8, T. 4 S., R.

 11 L'.~ at Ashurst-Hayden Dam. 10 miles northeast of Florence. Permanent crest or 

dam is 1,562.6 feet (revised) above mean sea level, datum of 1929. Crest height at 

times temporarily increased by use of flashboards. Florence-Casa Grande Canal diverts 

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

Drainage area.- 18,300 square miles.

Records available.- July 1923 to September 1942 (head on crest of dam only). Records of

 diversions to Klorence-Casa Grande Canal available January 1928 to September 194^.

Extremes^- Maximum head on dam during year, 1.36 fee,t Aug. 8; no flow over dam greater

Pal"l923-42: 'Maximum head on dam, 8.0 feet Sept. 28, 1926; no flow over dam greater 

part of each year.

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

 flramfe Canal. Diversion records are those at canal 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 the dam, 

except for water passed over the dam or sluiced through the dam during times of flood. 

Many diversions above station for irrigation. Flow regulated at Coolidge Dam except 

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

portion of unregulated inflow.

Cooperation.- Records of diversions to Florence-Casa Grande Canal furnished by Office

 of Indian Affairs; 20 discharge measurements made and records reviewed by Geological 

Survey.

Remarks.- Records good except those for periods of indefinite stage-discharge relation, 

those for days of fragmentary gage-height record, and thr , above 500 second-feet, 

all of which are fair. Small diversions above station foi Irrigation. For comparison 

of flow at present site and at former site 4 miles downstream, results of discharge

Drainage area.- 6,160 square miles at Bartlett Dam. 

Records available.- July 1939 to September 1942.

Extremes.- Maximum contents during year, 123,600 acre-feet Mar. 22 (gage height, 163.88 

feet); no storage July 29 to Sept. 4, Sept. 9, and Sept. 11 to 16.

1939-42: Maximum contents, 184,800 acre-feet Feb. 17, 1941 (gage height, 180.80 

feet), of which 2,200 acre-feet was uncontrolled storage; no storage at times.

Remarks.- Reservoir is formed by concrete multiple-arch dam; storage began Feb. 5, 1939;

 dam completed in May 1939. Capacity, 182,600 acre-feet between gage heights 0.0 

(sill of outlet gates) and 188.0 feet (top of spillway gates). Natural flow passing 

through reservoir when outlet gates are open prevents withdrawal of storage to gage 

height of gate sill. There is no dead storage. Water is used for irrigation of 

lands below reservoir and for municipal supply. Figures given herein represent usable 

contents.

(ll:30 p.m.) 27490 sec.-ft.; Aug. 6 (7 p.m.) 6,280 sec.-ft.

a No gage-height record; discharge computed on basis of rainfall records, adjoining good record, 

and comparison with falling stages of rises similar to that of Aug. 6.

Time basis; Mountain standard time prior to 2 a.m., Peb. 9, 1942; mountain war time thereafter. 

To convert war time to standard time, subtract 1 hour.
GILA RIVER BASIN 335

Agua Fria River at Lake Pleasant Dam, Ariz.

Location.- Staff gage, lat. 33°51', long. 112°16', in IJWi sec. 21, T. 6 N., R. 1 E., at

left upstream end of Lake Pleasant Dam, 24i miles upstream from mouth of New River.

Datum or 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 

Glendale, Ariz.), October 1933 to September 1942.

Extremes.- Maximum 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 

1941-42). 3. Effect of rainfall and evaporation on lake; evaporation assumed as 0.7 

of that measured once daily in 3-f.oot-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 the Maricopa County 

Municipal Water Conservation District No. 1.

feet), of which 500 acre-feet was uncontrolled storage; no storage Sept. 5, 1933, 

July 19 to Aug. 13, 1940.

Remarks.- Lake is formed by multiple-arch dam; dam completed and storage began in 1927. 

Capacity, 178,000 acre-feet between gage heights 57.0 feet (22.0 feet above center 

line of outlet works) and 170.0 feet (top of spillway gates). There is no storage 

below gage height 57.0 feet because of accumulated silt. Water released from 

reservoir flows down river channel li miles to diversion dam where it is diverted 

for Irrigation near Beardsley. Figures given herein represent usable contents in 

Lake Pleasant. Contents of small reservoir formed by diversion dam Is not Included.

Cooperation.- Gage-height record furnished by Marlcopa County Municipal Water Conservation District No. 1.
