SURFACE WATER SUPPLY OF THE COLORADO RIVER BASIN, 1943

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, 1943. 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 9,670 gaging stations 

In the 48 States and also at many gaging stations in Alaska and Hawaii. In July 1943, 

5,130 gaging stations, including those In Hawaii, were being maintained by the Geological 

Survey and cooperating organizations. Mlscellandous 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; In this 

report cooperation of the second kind is acknowledged on'pages 10-11.

DEFINITION OF TERMS

The units in which stream-flow data are presented in this report and other terns 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 quantity of water required to cover an acra to the 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 the volume of water represented by a flow of I 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.

"Contents" is a term applied to the volume of water in a reservoir, not including water 

In bank storage unless so indicated*

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 

measurements in determining the daily 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 nade 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 daily mean gage height to these rating tables gives the 

daily 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 daily 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 "shifting-control" 

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 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 daily 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; the minimum discharge if there is little or no regulation; the minimum daily 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 railes 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 gageheight graphs based on gage readings made once or twice daily 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 daily mean 

gage height may not indicate the true daily 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 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 moved 

ahead 1 hour, or to 3 a.m. Records of daily discharge prior to February 9, 1942, have been 

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

on the basis of war time. To convert war time to standard time, subtract 1 hour.
4 SURFACE WATER SUPPLY, 1943, PART 9

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 error in the daily 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 "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. 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 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 nay 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 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 data 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, 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. 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.

RECORDS OF DISCHARGE COLLECTED BY AGENCIES OTHER THAN THE GEOLOGICAL SURVEY

The Western Colorado Power Co. continued, during the water year October 1942 to September 1943, to collect records of daily discharge at a former Geological Survey station 

near Tacoma, Colo. These records, which cover the years 1926-43, are In the company's 

files.

The Soil Conservation Service of the United States Department of Agriculture began 

In 1936 to make studies of runoff from eight areas near Mexican Springs, N. Mex. Four 

of the areas comprise less than 3,000 acres each, two comprise between 3,000 and 10,000 

acres each, and two comprise between 10,000 and 21,000 acres each. These studies are still 

continuing, and records of them are 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: Office of the State Water Commissioner, J. C. Wanslee, prior to 

March 15, and State Land Department, 0. C. Williams, Commissioner, thereafter; 

Salt River Valley Water Users' Association; Metropolitan Water District of Southern 

California (for certain stations on Colorado River below Boulder Dam and oh Williams 

River); San Carlos Irrigation and Drainage District; and Marlcopa County Municipal

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 1943.

Average discharge.- 16 years (1918-34), 20,210 second-feet (unregulated); 9 years (1934-43), 

16,350 second-feet (adjusted to Include storage In Lake Mead).

Extremes.- Maximum dally discharge during year, 22,200 second-feet Oct. 10; maximum elevation, 452.37 feet July 19; minimum discharge, 11,600 second-feet Aug. 3; minimum eleva- 

. tion, 443.45 feet Oct. 1.

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

June 22, 1931; minimum, 1,480 second-feet Aug. 17, 1934.

1935-43 (regulated): Maximum discharge, 35,700 second-feet Jan. 29, 1942: minimum, 

,375 second-feet Feb. 14, 1935; minimum daily, 422 second-feet Feb. 14. 1935: maximum 

elevation, that of July 19, 1943.

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 1857-68 and most likely In the high 

years 1862 or 1867.

Remarks.- Records good. 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.

All-American Canal above Pilot Knob wasteway, Calif.

Location.- Water-stage recorder, lat. 33°45', long. 114°42', In SEi sec. 24, T. 16 S.,

 R. !ii E., San Bernardlno meridian, at bridge on U. S. Highway 80, 1 mile upstream 

from Pilot Knob wasteway, 5 miles downstrem from turnout to Yuma Main Canal, 5« miles 

northwest of Yuma, and 19i miles downstream from Intake at Imperial Dam. Datum of 

gage Is 148.52 feet above mean sea level, datum of 1929. 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 1943.

Extremes.- Maximum discharge during year, 5,240 second-feet Mar. 31; maximum gage height, 

13.80 feet July 21; no flow part of July 21 when Pilot Knob check gates were closed

f0ri938^43?llDMaxlmum discharge, that of Mar. 31, 1943; maximum gage height, that of 

July 21, 1943; 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 for 

power development and Irrigation In Imperial and Coachella Valleys, except for canal 

losses and waste at Pilot Knob wasteway. No flow through Pilot Knob wasteway during 

year except negligible leakage.

 tallrace at power plant, lat. 32°46'3011 , long. IWSS'OO", In SEiSEi sec. 10,

T. 16 S., R. 22 E., San Barnardlno meridian, 500 feet downstream from turnout In AllAmerican Canal to Yuma Main Canal, 3i miles north of Yuma, and 14i 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 pf 1929 (subject to 

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

Records available.- October 1938 to September 1943.

Extremes.- Maximum dally discharge during year, 2,040 second-feet Nov. 11; minimum dally, 

1,171) second-feet June 14.

1938-43: Maximum dally discharge, that of Nov. 11, 1943; 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 

formula. Rating of turbines checked by current-meter measurements. Records show quantity of water diverted from All-Amerlcan Canal for power development, irrigation on 

Valley division of Yuma project, and water returned to Colorado River through Yuma Main 

Canal wasteway (see p. 35) 3 miles downstream.

COOT 3ration.- Record of gage heights on forebay and of turbine gate openings furnished by 

ureau or Reclamation.

34 COLORADO RIVER MAIN STEM

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

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

recorder, lat. 32°43'45", long. 114037'15", in SWiSEi sec. 26, T. 16 S., R. 22 E., San 

Bernardino meridian, on California side of river, 500 feet downstream from Yuma Main 

Canal wasteway and 3 miles downstream from siphon-drop power plant. At outlet, waterstage recorder in NWiNEi sec. 35, T. 16 S., R. 22 E., San Bernardino 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 1929).

Records available.- October 1938 to September 1943.

COLORADO RIVER MAIN STEM 35

Yuma Main Canal wasteway at Yuma, Ariz.

Location.- Yuma Main Canal wasteway receives water from Yuma Main Canal at gates, lat. 

32"44'00", long. 114°37'15", In SWiSEi sec. 26, T. 16 S., R. 22 E., San Bernardino 

meridian, 500 feet upstream from Intake of Colorado River siphon on Yuma Main Canal, 

half a mile north of Yuma, and 3 miles downstream from siphon-drop power plant on 

Yuma Main Canal. The wasteway discharges Into Colorado River half a mile downstream 

from station on Colorado River at Yuma.

Records available.- April 1913 to September 1943 (prior to October 1930, yearly discharge 

only, see Wate?-Supply Paper 879; 1930-38, published as separate table In records for 

Colorado River at Yuma.)

Extremes.- Maximum dally discharge during year, 1,670 second-feet July 11; minimum 

dally, 490 second-feet June 14,

1930-43: Maximum dally discharge, 1,900 second-feet Feb. 21, 1932: no flow several 

days In 1937, 1938, 1939.

Remarks.- Records good. Discharge computed as difference between discharge of Yuma Main 

Canal at siphon-drop power plant and that of same canal below Colorado River siphon, 

with deduction for small Irrigation diversions from canal between those stations. 

Records do not include 35,900 acre-feet from California Drainage Canal returned during 

water year to Colorado River at mouth of wasteway.

Cooperation.- Record of diversions for irrigation from Yuma Main Canal and discharge from 

California Drainage Canal furnished by Bureau of Reclamation.

» Winter discharge measurement made on this day.

Note.- Stage-discharge relation affected by ice Dec. 11-19. No gage-height record Dec. 20 to 

Apr. 10 (stage-discharge relation affected by ice during most of period); discharge computed on 

basis of three discharge measurements and weather records. 

Time basis; Mountain war time. To convert war time to standard time, subtract 1 hour.
TRIBUTARIES ABOVE GREEN RIVSR 

Gunnison River near Grand Junction, Colo.

near mouth), April 1917 to September 1928 and January 1934 to September 1943 (at present site) in reports of Geological Survey. April 1917 to September 1930 and January 

1934 to September 1943 in reports of State engineer.

Average discharge (river and power canal).- 23 years (1917-30, 1933-43), 2,998 second- 

-feet.

Extremes (combined flow of river and power canal).- Maximum discharge, 13,700 secondfeet my 5; minimum daily, 704 second-feet July 29.

1917-30, 1933-43: Maximum discharge observed, 35,700 second-feet Hay 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. 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 Gunnison River Basin. 

Figures of discharge include flow of power canal.

at site Just downstream from Dry Fork. October 1911 to June 1914 at power plant li 

miles downstream.

Average discharge.- 27 years (1914-16, 1918-43), 105 second-feet.

Extremes.- Maximum discharge during year, 702 second-feet Apr. 30 (gage height, 2.97 feet); 

minimum, 16 second-feet Mar. 21.

1911-43: Maximum discharge, 2,050 second-feet my 29, 1921; minimum recorded, 16 

second-feet Mar. 21, 1937, Mar. 21, 1943.

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

Flow Is Increased by water released from Oaks Park Reservoir (capacity, 6,250 acre-feet) 

on Brush Creek and diverted to Ashley Creek Basin for Irrigation. City of Vernal pipe 

line (capacity, approximately 5 second-feet) diverts water from tributary spring 1,000 

feet above station (diversion began Aug. 1, 194l). At times, part of this flow Is returned to Ashley Creek half a mile below gage.

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

River. Datum of gage 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 1943 In reports of Geological Survey. January to October 1911 and 

November 1915 to December 1931 in reports of State engineer.

Average discharge.- 23 years (1916-20, 1921-25, 1927-31, 1932-43), 2,898 second-feet.

Extremes.- Ifcximuin discharge during year, 10,700 second-feet Hay 5 (gage height, 6.90 

feet); minimum daily, 270 second-feet Jan. 20.

1930-31, 1932-43: 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. Diversions above station for irrigation.

Discharge, in second-feet, water year October 1942 to September 1943

Records available.- November 1911 to June 1912, April 1913 to September 1914 (fragmentary), 

and October 1940 to September 1943 in reports of Geological Survey. April 1913 to September 1914, April 1920 to September 1928 (no winter records prior to 1928), and October 1940 to September 1943 in reports of State engineer. Figures for flood of May and 

June 1920, published in reports of State engineer, are considered too high from information by his office.

Extremes.- Maximum discharge during year, 865 second-feet May 1 (gage height, 3.33 feet); 

minimum daily, 15 second-feet Jan. 19.

1920-28, 1940-43: Maximum discharge, 3,040 second-feet Sept. 12, 1927 (gage height, 

8.50 feet, site and datum then in use, from floodmarks), by slope-area method; minimum 

daily recorded, 12 second-feet Jan. 4, 1941, but may have been less during periods of 

no record.

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

which are fair. Diversions above station for irrigation.

QILA RIVER BASIN 295

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

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

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

a point 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 five 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. Mex. The intake of York Canal at western end is 5 miles upstream from station on Gila 

River hear Clifton, Ariz.

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 diversions since January 1936, except for Sunset, Moddle, and Shriver Canals 

for 1939-43, have been furnished by 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. 302-3CT7 for records of Sunset, Moddle, and Shriver Canals 

for 1943.

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

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

GILA RIVER BASIN 

Diversions from Gila River in Safford Valley, Arlz.

299

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

of Bonlta Creek on the east to San Carlos Indian Reservation on the west. Twelve canals, 

listed in following table in downstream order, and one pump divert water from Gila River 

for irrigation in valley. Intake of Brown Canal, at upper end of valley, is threequarters of a mile upstream from station on Gila River near Solomonsville. Intake of 

Colvln-Jones Canal, at lower end, is 20 miles upstream from station on Gila River near 

Calva.

Records of monthly diversion for all canals except Fourness, Fort Thomas, and ColvlnJones are available for IQM-IS; records of daily and monthly diversions for all canals 

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

also for water year 1931-32 (Tidwell Canal published as Michelana Canal in records for 

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

1936-43.

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

Commissioner, appointed by U. S. District Court for Arizona. Water-stage recorders with 

Parshall flumes or weirs were used by water commissioner to obtain records of diversion 

by canals, and rated pump was used to obtain record of pumped water. See records for 

Gila River at Safford for flow of Gila River between intakes of Graham and Smlthville 

Canals.

The following tabulation of annual diversion by each canal and combined monthly diversion by canals as a group have been compiled and furnished by Gila Water Commissioner.

Annual diversions, In acre-feet, to each canal during water year 1942-43 

and calendar year 1942

306 01LA RIVER BASIN

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

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

 11 b!., 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 increased 1.34 

inches all 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 1943 (head on crest of dam only). Records 

or diversions to Florence-Casa Grande C^nal available January 1928 to September 1943.

Extremes.- Maximum head on dam during year, 2.22 feet Aug. 10; no flow over dam greater 

part of year.

1923-43: 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 

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

extensive sluicing. 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 dam, 

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

diversions above station for irrigation. Flow regulated by Coolldge 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 1942 to September 1943

308 GILA RIVER BASIN

Gila River below Gillespie Dam, Ariz.

Location.- Water-stage recorder above left end of Gillespie Dam, lat. 33°14', long. 

112"45", in S5iNE4 sec. 28, T. 2 S., R. 5 W., 8 miles downstream from Hassayampa 

River. Average elevation of crest of dam is 753.46 feet above' mean sea level, datum 

of 1929, and 5 feet above datum of gage. Gillespie Canal diverts from left bank and 

Enterprise Canal diverts from right bank at Gillespie Dam.

Drainage area.- 49,600 square miles.

Records available.- August 1921 to September 1943 (river only). Records for Gillespie 

Canal May 1935 to September 1943; for Enterprise Canal June 1935 to September 1939 

(discharge measurements only), October 1939 to September 1943.

Extremes.- Maximum discharge during year, 2,200 second-feet Aug. 5 (height over crest of 

dam, 0.75 foot); no flow for several periods during year.

1921-43: Maximum discharge, 70,000 second-feet Dec. 28, 1923 (height over crest 

of dam, 6.0 feet), by computation of flow over dam; no flow for several periods In 

each year.

Maximum discharge known, 250,000 second-feet (estimated) in February 1891.

Remarks.- River records good except those below 100 second-feet and those for periods of 

no gage-height record, which are fair. Records include flow over crest and through 

sluice gates of Gillespie Dam but do not include flow in Gillespie and Enterprise 

Canals which divert from river immediately above dam. Other diversions above station

Conservation District No. 1).

Drainage area.- 588 square miles.

Records available^- January 1940 to September 1943.

Extremes.- Maximum discharge during year, 3,500 second-feet Sept. 25 (gage height, 6.70 

reet), from rating curve extended above 1,200 second-feet on basis of slope^area determinations at gage heights 9.44 and 11.97 feet; negligible flow at times during summer 

months when entire flow was diverted to Perry Canal above station, seepage flow only 

past gage.

1940-43: Maximum discharge, 13,000 second-feet Mar. 1, 1941 (gage height, 11.97 

feet), by slope-area method; negligible flow at times during summer months In most 

years when entire flow was diverted to Perry Canal above station, seepage flow only 

past gage.

Remarks.- Records good except those for Aug. 2 to Sept. 17, which are fair. Diversions 

aoove station for irrigation and mining. Figures of dally discharge do not include 

water diverted Just above station to Perry Canal.

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

lert upstream end of Lake Pleasant Dam, 2A\ miles upstream from mouth of New River. 

Datum of 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 

uienaaie), uccoDer 1933 to September 1943.

Extremes.- FfeLXimum 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. Discnarge computed on basis of three factors as follows: 1. Change in contents of Lake 

Pleasant and in contents of small reservoir behind diversion dam \\ 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 1942-43). 

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 Maricopa County Municipal 

water conservation District No. 1.

1928-43: Maximum contents, 178,500 acre-feet Apr. 19, 1941 (gage height, 170.13 

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 1-J 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.
