SURFACE WATER SUPPLY OF THE COLORADO RIVER BASIN, 1954

SCOPE OF WORK

This volume is one of a series of 18 reports presenting measurements of stage, discharge, 

and content of streams, lakes, and reservoirs in the United States during the water year 

ending September 30, 1954. Since 1888, when the United States Geological Survey first studied streamflow in relation to problems of irrigation, similar measurements have been made at 

more than 13,050 gaging stations in the 48 States and at many others in the Territories of 

Alaska and Hawaii. On September 30, 1954, the Geological Survey and cooperating organizations were maintaining 6,750 gaging stations, including those in Alaska and Hawaii. Discharge measurements only were made at many other points in the 1954 water year, most of 

which are published at the end of this report.

DEFINITION OF TERMS AND ABBREVIATIONS

The terms of streamflow and other hydrologlc data, as used in this report, are defined 

as follows:

Cubic foot per second (cfs) 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.

Cubic feet per second per square mile (cfsm) is the average number of cubic feet of 

water flowing per second from each square mile of area drained, assuming that the runoff 

is distributed uniformly in 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. The term is used 

for comparing runoff with rainfall, which is also usually expressed in inches.

Acre-foot is the quantity of water required to cover an acre to the depth of 1 foot and 

is equivalent to 43,560 cubic feet. The term is commonly used in relation to storage for 

irrigation,

Cfs-day is the volume of water represented by a flow of 1 cubic foot per second for 

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

and represents a runoff of 0.0372 inch from 1 square mile.

Stage-discharge relation is the relation between gage height and the amount of water 

flowing in a channel, expressed as volume per unit of time.

Control designates a feature downstream from the gage that determines the stage-discharge 

relation at the gage. This feature may be a natural constriction of the channel, a long 

reach of the channel, or an artificial structure.

Contents is the volume of water in a reservoir. Unless otherwise indicated, volume is 

computed on the basis of a level pool and does not include bank storage. 

The drainage area of a stream at. a specified location is that area, measured in a
EXPLANATION OF DATA 3

horizontal plane, which is so enclosed by a topographic divide that direct surface rurioff 

from precipitation normally would drain by gravity into the river above the specified 

point. Figures of drainage area given herein include all closed basins, or noncontributing areas, within the area unless otherwise noted.

WSP is used as an abbreviation for "Water-Supply Paper" in references to previously 

published reports.

DOWNSTREAM ORDER OF LISTING GAGING STATIONS

Beginning with the series of reports for the water year ending September 30, 1951, the 

order of listing gaging-station records was changed. In this report, In a downstream direction along the main stem all stations on a tributary entering above a main-stem station 

are listed before that station. If a tributary enters between two main-stem stations, it 

is listed between them. A similar order is followed in listing stations on first rank, 

second rank, and other ranks of tributaries. To indicate the rank of any tributary on 

which a gaging station is situated and the stream to which it is immediately tributary, 

each indention in the listing of gaging stations in the table of contents of this report 

represents one rank. This downstream order and system of indention show which gaging stations are on tributaries between any two stations on a main stem and the rank of the tributary on which each gaging station is situated.

The order of listing used before the publication of the 1951 report listed first all 

stations on the main stem from headwaters toward mouth, then all stations on the uppermost 

tributary to the main stem from the tributary's source to mouth, and then all stations from 

source to mouth of the uppermost tributary to the tributary.

EXPLANATION OF DATA

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

of discharge. In addition, observations of factors affecting the stage-discharge relation, 

weather records, and other information are used to supplement base data 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 fluctuations. 

Measurements of discharge are made with a current meter by the general methods adopted 

by the Geological Survey on the basis of experience in stream gaging since 1888. These 

methods are described in Water-Supply Paper 888 and are also outlined in standard textbooks 

on the measurement of stream discharge. Typical structures in use at gaging stations are 

shown in figure 1.

Rating tables giving the discharge for any stage are prepared from stage-discharge relation curves defined by discharge measurements. If extensions to the rating curves are 

necessary to define the extremes of discharge, they are made on the basis of indirect 

determinations of peak discharge (such as slope-area or contracted-opening determinations, 

computation of flow over dams or weirs, and by other methods), velocity-area studies, and 

logarithmic plotting. The application of the daily mean gage height to those 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

FIGURE 1. GAGING-STATION STRUCTURES
EXPLANATION OP DATA 5

based on individual discharge measurements and notes by engineers and observers are used 

in applying the gage heights to the rating tables. If the stage-discharge relation for 

a station is temporarily changed by the presence of aquatic growth or debris on the control , the daily mean discharge is computed by what is essentially the shifting-control 

method.

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

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

method in which the slope or fall in a reach of the stream is a factor in determining 

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 stagedischarge relation is affected by changing stage. If so, the rate of change in 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, and it becomes 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 other stations in the same or nearby basins. If the 

stage-discharge relation is affected by ice, this information is given in a note to the 

table. No mention is made of occasional days of ice effect if the degree of accuracy of 

daily records is not changed. Records are published for the water year which begins on 

October 1 and ends on September 30. A calendar for the water year 1954 is shown on page 

IV for the purpose of finding the day of the week for any date.

The data herein presented generally comprise a description of the station, a skeleton 

rating table, and a table showing the daily discharge and monthly and yearly discharge 

and runoff of the stream.

The description of the station gives the location, drainage area, records available, 

type and history of gages, average discharge, extremes of discharge, general remarks, and 

notations of revisions of the previously published record. The location of the gaging 

station and the drainage area are obtained from the most accurate maps available. River 

mileage, given under "Location" for some stations, is that determined and used by the 

Corps of Engineers unless otherwise noted. Under "Records available" are given the periods 

for which there are published records generally equivalent to those at the present site. 

Under "Gage" are given the type of gage currently in use and the datum of the present gage 

above mean sea level, and a condensed history of the types, locations, and datums of previous gages used during the period of records available. Under "Average discharge" is 

given the average discharge for the number of years indicated. It is not given for stations having fewer than five complete years of record or for stations where changes in 

water development during the period of record cause the figure to have little significance. 

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). In the first paragraph, the data given are for the complete current 

water year unless otherwise specified. In the second paragraph, the data given are for the 

periods of record within the calendar year dates in the heading (not necessarily those for 

the complete years indicated by the heading dates). Reliable information concerning major

406704 O -56 -Z
6 SURFACE WATER SUPPLY, 1954, PART 9

floods that have occurred outside the period of record are given in the third or last 

paragraph under "Extremes." Unless otherwise qualified, the maximum discharge corresponds 

to the crest stage obtained by use of a water-stage recorder, a crest-stage indicator, or 

a nonrecording gage read at the time of the crest. If the maximum gage height did not 

occur at the same time as the maximum discharge, it is given separately. Information pertaining to the accuracy of the records and conditions which affect the natural flow at the 

gaging station is given under "Remarks."

Previously published records of some stations have been found to be in error on the 

basis of data or information later obtained. Revisions of such records are usually published along with the current records in one of the annual reports. In order to make it 

easier to find such revised records, a paragraph headed "Revisions (water years)" has been 

added to the description of all stations for which revised records have been published. 

Listed therein are all the reports in which revisions have been published, each followed 

by the water years for which figures are revised in that report. In listing the water 

years only one number is given; for instance, 1933 stands for the water year October 1, 

1932, to September 30, 1933. If no daily, monthly, or annual figures of discharge are concerned in the revision, that fact is brought out by notations after the year dates as follows: "(M)" means that only the instantaneous maximum discharge was revised; "(m)" that 

only the instantaneous minimum was revised; and "(P)" that only peak discharges were revised. If the drainage area has been revised, the report in which the revised figure was 

first published is given. It should be noted that for all stations for which cubic feet 

per second per square mile and runoff in inches are published, a revision of the drainage 

area necessitates corresponding revision of all figures based on the drainage area. Revised figures of cubic feet per second per square mile and runoff in inches resulting from 

a revision of the drainage area only, are usually not published in the annual series of reports .

Skeleton rating tables are published for all stations except those at which the daily 

discharge for the greater part of the open-water period was determined by the shiftingcontrol method, the slope method, or other special methods involving an equivalent adjustment to the gage height of more than one-tenth foot. Skeleton rating tables are generally 

not published for stations on canals.

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

sudden or rapid fluctuation, the daily 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. 

For stations equipped with nonrecording gages, the table'of daily discharge gives the discharge corresponding to once-daily readings of the gage, or to the mean of twice-daily 

readings, or to the mean gage height determined from gage-height graphs based on gage 

readings. For periods of rapidly changing stage, the daily mean discharge is determined 

from gage-height graphs based on gage readings, the frequency of which is stated in the 

station description.

In the table of daily discharge, the figures for the maximum day and the minimum day for 

each month are underlined. If the figure is repeated, it is underlined only on the first 

day of its occurrence.
ACCURACY OF FIELD DATA AMD COMPUTED RESULTS 7

In the monthly summary below the daily table, the line headed "Total" gives the sum of 

the daily figures; it is the total cfs-days for the month. The line headed "Mean" gives 

the average flow in cubic feet per second during the month. Runoff for the month may be 

expressed in cubic feet per second per square mile (line headed "Cfsm"), or in inches (line 

headed "In."), or in acre-feet (line headed "Ac-ft"). Figures for cubic feet per second per 

square mile and runoff in inches are omitted if the drainage area includes large noncontributing areas, or if the average annual rainfall over the drainage basin is usually less than 

20 inches.

In the yearly summary below the monthly summary, the figures of maximum are the maximum 

daily discharges, not the momentary discharges when the water was at crest stage. Likewise, the minimums in this summary are the minimum daily discharges.

Peak discharges and the times of their occurrence and corresponding gage heights of 

most stations are listed below the table of daily and monthly discharge. All independent 

peaks above the selected base are given. The base discharge, which is given in parentheses, is selected so that an average of about three peaks a year will be presented. 

Peak discharges are not published for canals, ditches, drains, or for any stream for which 

the peaks are subject to substantial control by man.

Footnotes to the table of daily discharge indicate periods when discharge was computed 

or estimated by unusual or special methods during periods of no gage-height record and ice 

effect, or by other effects that reduce the degree of accuracy of the records. Days on 

which discharge measurements were made are indicated by asterisk ana footnote unless they 

Here made at frequent regular intervals, in which instance the general frequency of discharge measurements is given under "Remarks" in the station description.

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 or stage is given. A skeleton table of capacity at given 

stages is usually given in the first report in which data for the reservoir are published, 

but it is omitted from succeeding reports.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of streamflow data depends primarily on (1) the stability 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 discharge, and interpretation of records.

The station description states the degree of 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 nearly accurate than the daily records.

Runoff at some stations, as indicated by the monthly mean, may vary widely from natural 

runoff, owing to diversion, consumption, regulation by storage, increase or decrease in 

evaporation due to artificial causes, or to other factors. For such stations, values of 

cubic feet per second per square mile and runoff in inches are not published unless storage or diversion records are included to indicate 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 it is so stated.
SURFACE WATER SUPPLY, 1954 , PART 9

Even at those stations where adjustments are made, large errors in computed runoff may 

occur when relatively large negative adjustments are made or when evaporation is large in 

comparison with the observed discharge.

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 actually show the water supply available at the stations for further development, 

because water must first be supplied to existing irrigation systems.

PUBLICATIONS

To facilitate publication of the annual series of reports, the area of the United 

States is divided into 14 parts whose boundaries coincide with certain natural drainage 

lines. Formerly, the results of streamflow measurements were published in 14 volumes, one 

for each of the 14 parts. Beginning with the reports for 1951, the records are published 

in 18 volumes, there being 2 volumes each for Parts 1, 2, 3, and 6. The boundaries of the

The records at most of the stations discussed in these reports extend over many years. 

Discharge 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 are listed in the same order as the 

streams and gaging stations in the body of the report. An index of the records obtained 

before 1904 has been published in Water-Supply Paper 119.

A compilation of records for the area covered by this report through September 1950 

has been published as WSP 1313. That report contains a summary of monthly and annual 

discharges for all previously published records as well as some records not contained in 

the annual series of water-supply papers. All records were reexamined and revised where 

warranted. Estimates of discharge were made to fill short gaps whenever practical.

Records of discharge have been published also in State reports. Most of these records are compiled in WSP 1313, however some of them are not contained in the publications 

of the Geological Survey. The following table contains a list of these reports for the 

area covered by this report.

The reports listed in the foregoing tablee contain the customary records of discharge 

collected during the systematic operation of gaging stations. Detailed information on 

the stage and discharge of many streams during major floods has been included in special 

reports on these floods published by the Geological Survey. The more recent of these 

special reports also contain other pertinent hydrologic information and analyses and 

compilations of data relating to earlier notable floods. The following list gives the 

numbers and titles of these reports.

RECORDS OF DISCHARGE COLLECTED BY AGENCIES OTHER THAN THE GEOLOGICAL SURVEY

The Agricultural Research Service of the United States Department of Agriculture has 

been collecting records of runoff near Safford, Ariz., beginning in 1938, from 6 areas 

of less than 800 acres. These records are in the files of the Agricultural Research 

Service.

HYDROLOGIC CONDITIONS

The water year was characterized by deficient runoff over most of the area covered 

by this report. New record-lows were experienced in Arizona during the period October 

to February. In March the Upper Gila River basin was above median for the first time 

since June 1952. Runoff of Colorado River near Cisco, Utah, was the lowest ever recorded 

in May and June. A notable flood occurred in Queen Creek in the Gila River basin 

August 19 causing an estimated one million dollar damage. Runoff was also the highest 

for August since 1934 for Gila River at head of Safford Valley near Solomon, Ariz. In 

the Tucson area, the runoff for Santa Cruz River for the July and August period was the 

highest for period of record beginning in 1906. For those key gaging stations in the area 

covered by this report, a comparison of monthly and annual mean discharges during the 1954 

water year with the median discharges for the 25-year period 1921-45 is shown in figure 

3 on the following page.

T929. Prior to Oct. 27, 1948, at site a quarter of a mile upstream at datum 4.86 ft 

higher.

Average discharge. 16 years, 124 efs (89,770 aere-ft per year).

Extremes. Maximum discharge during year, 642 efs Oct. 23 (gage height, 3.98 ft); minimum 

daily, 25 efs Mar. 29.

1938-54: Maximum discharge, 2,950 efs Aug. 5, 1945 (gage height, 7.76 ft, site and 

datum then in use), from rating curve extended above 1,300 efs; minimum observed, 

11 efs (discharge measurement) Feb. 1, 1951.

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

which are poor. Part of discharge is return flow from irrigated lands under lower end 

of Ironstone Canal from Uneompahgre River. Diversions for irrigation of a few hundred 

acres above station.

GUNNISON RIVER BASIN 123

Gunnison River near Grand Junction, Colo.

Location.--Lat 39°02', long 108°34', in NW£ sec. 35, T. IS., R. 1 W., Ute meridian, on 

left bank of river and right bank of canal, half a mile downstream from point of diversion of Redlands power canal and 2 miles upstream from mouth and Grand Junction.

Drainage area. 8,020 sq mi, approximately.

Records available. October 1894 to December 1895 (gage heights only), October 1896 to 

September 1899, October 1901 to October 1906, October 1916 to September 1954 (October 

1928 to December 1933 monthly discharge only, published in WSP 1313). Published as 

"at Whitewater," 1901-6.

Gages.--River: Water-stage recorder. Datum of gage is 4,555.14 ft above mean sea level, 

datum of 1929. Prior to Apr. 1, 1917, staff or chain gages at several sites l| miles 

downstream near mouth and 12 miles upstream at Whitewater at various daturns. Apr. 1, 

1917, to June 24, 1934, staff gage at present site and datum.

Canal: Water-stage recorder at same point as gage on river and at datum 12.0 ft 

higher. Apr. 1, 1917, to Apr. 23, 1936, staff gage half a mile upstream at different 

datum.

Average discharge (combined flow). 46 years (1896-99, 1901-6, 1916-54), 2,690 cfs 

(1,947,000 acre-ft per year).

Extremes (combined flow). '--Maximum discharge during year, 4,570 cfs Oct. 23; minimum daily, 

272 cfs July 4.

1896-99, 1901-6, 1916-54: Maximum discharge observed, 35,700 cfs May 23, 1920 (gage 

height, 14.95 ft), from rating curve extended above 22,000 cfs; minimum daily, 106 cfs 

July 20, 1934.

Remarks. Records good except those for periods of ice effect, which are fair. Redlands 

power canal diverts water above river station and returns it to Colorado River below 

mouth of .Gunnison River. Records show combined flow of river and Redlands power canal 

and except for about 40 cfs diverted below gage during irrigation season represents 

entire flow that enters Colorado River from Gunnison River basin. Natural flow of 

river affected by diversions for irrigation of about 233,000 acres above station, small 

diversions out of basin, small storage reservoirs, and return flow from irrigated lands. 

Records of chemical analyses and water temperatures for the water year 1954 are given 

in WSP 1353.

246 GREEN RIVER BASIN

Uinta River near Neola, Utah

Location. Lat 40 032'10", long 110°04'00", in SW£ sec. 25, T. 2 N., R. 2 W., Uinta merldian, on left bank 300 ft downstream from bridge, three-quarters of a miles upstream 

from Pole Creek, and 7 miles north of Neola.

Drainage area. 181 sq mi.

Records available. July 1921 to September 1927 (no winter records 1922-25, 1927), September 1929 to September 1954.

Gage. Water-stage recorder. Altitude of gage is 6,910 ft (from river-profile map). 

Prior to Aug. 4, 1951, water-stage recorder, staff or chain gages at several sites 

within 2,000 ft of present site at various datums. Aug. 4, 1951, to Aug. 11, 1952, 

water-stage recorder at present site at datum 1.14 ft higher.

Average discharge. 26 years (1925-26, 1929-54), 174 cfs (126,000 acre-ft per year).

Extremes. Maximum discharge during year, 856 cfs May 22 (gage height, 3.63 ft); minimum, 

24 cfs Mar. 31, Apr. 1.

1929-54: Maximum discharge, 3,320 cfs June 26, 1944 (gage height, 5.20 ft, site and 

datum then in use), from rating curve extended above 1,600 cfs; maximum gage height, 

5.57 ft June 18, 1949, site and datum then in use; minimum discharge recorded, that of 

Mar. 31, Apr. 1, 1954.

Remarks. Records good except those for periods of ice effect, which are fair. Water 

3Tverted from Pole Creek and Uinta River and used at powerplant of Uinta Power & Light 

Co., enters river about 1,000 ft above station. Uinta power canal diverts from river 

6 miles above station. Enlargement of canal completed in August 1944. Plow through 

canal increased Oct. 12, 13, 1944, and held nearly constant thereafter. Power canal 

and Pole Creek diversion feed to common forebay. Water not used through powerplant 

wastes through spillway of forebay at penstock Intake and enters river a short distance 

above station. Prior to Nov. 18, 1948, spill entered river half a mile below station. 

Considerable spill occurs at times when 1 of 2 power units is not operating. Summer 

flow slightly regulated by storage in several small mountain lakes and reservoirs.

November 1945, reference point at site 100 ft upstream at different datum.

Average discharge. 8 years (1946-54), 113 cfs (81,810 acre-ft per year).

Extremes. Maximum discharge during year, 5,420 cfs Sept. 4 (gage height, 5.58 ft); minimum, 15 cfs Aug. 4.

1909-11, 1945-54: Maximum discharge observed, 8,150 cfs Sept. 1, 1909 (gage height, 

1.8 ft below reference point, site and datum then In use), from rating curve based on 

many float determinations; no flow for several days during July, August, and September 

1910.

Remarks. Records good except those for periods of ice effect, doubtful, fragmentary, or 

no gage-height record, which are fair. Discharge measurements generally made once a 

week. Diversions above station for irrigation of about 18,000 acres, most of which is 

above station. Plow affected by storage in Scofield Reservoir since 1926 (see p. 267). 

Records of chemical analyses and water temperatures for the water year 1954 are given 

in WSP 1353.

Saleratus Wash at Green River, Utah

Location. Lat 39 0 00', long 110°09' , in NE^ sec. 16, T. 21 S., R. 16 E., on right bank 

about 500 ft south of railroad crossing on State Highway 24, half a mile southeast of 

town of Green River, and three-quarters of a mile upstream from mouth.

Records available. October 1948 to September 1954.

Gage. Water-stage recorder. Altitude of gage is 4,065 ft (from river-profile map).

Average discharge. 6 years, 2.92 cfs (2,110 acre-ft per year).

Extremes. Maximum discharge during year, 2,340 cfs Sept. 13 (gage height, 7.72 ft), from 

rating curve extended above 650 cfs on basis of slope-area determination of peak flow; 

no flow at times.

1948-54: Maximum discharge, 4,850 cfs July 8, 1950 (gage height, 8.67 ft), from 

rating curve extended above 650 cfs on basis of slope-area determinations at gage 

heights 6.10 and 8.67 ft; no flow at times.

Remarks. Records poor. Most of low flow is due to leakage from an irrigation flume which 

crosses the wash a short distance upstream and return flow from irrigation in immediate 

vicinity of station.

Discharge, In cubic feet per second, water year October 1953 to September 1954

datum. Mar. 15, 1940, to Oct. 12, 1941, and Feb. 16, 1951, to Mar. 10, 1954, waterstage recorder at site 600 ft downstream at datum 4.95 ft lower.

Average discharge. 26 years, 61.1 cfs (44,230 acre-ft per year).

Extremes.--Maximum discharge during year, 942 cfs Oct. 23 (gage height, 5.12 ft, site and 

datum then in use), from rating curve extended above 420 cfs on basis of slope-area 

determination at gage height 9.15 ft; no flow for many days in June and July.

1920-43, 1951-54: Maximum discharge, 5,300 cfs Oct. 14, 1941 (gage height, 7.30 ft, 

present site and datum), from rating curve extended above 200 cfs on basis of slopearea determination of peak flow; no flow at times for most years.

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

which are poor. Diversions for irrigation of about 10,000 acres above station. One 

diversion above station for irrigation of about 100 acres below station.

330 SAN JUAN RIVER BASIN

San Juan River near Bluff, Utah

Location. Lat 37°09', long 109°52', in SWir sec. 7, T. 42 S., R. 19 E., on left bank 

1,600 ft downstream from 'Gypsum Creek, 1,800 ft upstream from bridge, 20 miles southwest of Bluff, and 114 miles upstream from mouth.

Drainage area. 23,000 sq mi, approximately.

Records available. October 1914 to September 1954 (October 1917 to February 1927 monthly 

discharge only, published in WSP 1313).

Gage. Water-stage recorder. Altitude of gage is 4,050 ft (from river-profile map). 

Prior to Mar. 16, 1927, chain gages at sites about 1,700 ft downstream at different 

datum.

Average discharge. 40 years (1914-54), 2,879 cfs.

Extremes. Maximum discharge during year, 13,600 cfs Sept. 23 (gage height, 12.40 ft); 

minimum, 132 cfs Oct. 4.

1914-17, 1927-54: Maximum discharge, 70,000 cfs Sept. 10, 1927 (gage height, 32.0 

ft), from rating curve extended above 30,000 cfs; no flow July 3-13, 1934, Aug. 24-27, 

29, 1939.

Flood of Oct. 6, 1911, which is greatest known at Shiprock, New Mex., probably 

exceeded that of Sept. 10, 1927, at this station, but stage was not accurately determined .

Remarks. Records good. Discharge measurements generally made six times a week. Diversions for irrigation of about 190,000 acres above station. No diversion between station 

and mouth of river. Records of chemical analyses, water temperatures, and suspended 

sediment loads for the water year 1954 are given in WSP 1353.

Revisions (wateryears) . WSP 1213: 1940. WSP 1313: 1917, 1929. Figure of monthly runoff, 

for August 1945 published in WSP 1313 is corrected to 95,820 acre-ft.

Extremes. Maximum discharge during year, 1,600 cfs Sept. 11 (gage height, 7.38 ft), from 

rating curve extended as explanined below; no flow for many days.

1950-54: Maximum discharge, 4,390 cfs July 30, 1953 (gage height, 9.35 ft), from 

rating curve extended above 100 efs on basis of slope-area determinations at gage 

heights 7.20 and 7.76 ft and logarithmic plotting; no flow for many days during each 

year.

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

 which are poor. Diversions for irrigation of about 2,700 acres above station. Plow

may be slightly affected by transmountain diversion from East Pork Sevier River, which

is used for irrigation above station.

Water-stage recorder on Lyman Reservoir for determination of flow in spillway channel 

three-eighths of a mile north in SW£ sec. 4, T. 11 N., R. 28 E.

Average discharge. 12 years (1941-53), 2.73 efs (1,980 acre-ft per year).

Extremes. Maximum daily discharge during period Oct. 1 to June 30, 3 7 cfs May 5 6- no 

flow for several months. ' 

1941-54: Maximum discharge observed, 603 efs May 8, 1941 (including 546 cfs of 

spilled water); no flow at times.

Remarks. Records fair. Record of daily disenarge shows all water spilled and released 

from Lyman Reservoir to the river channel, but does not include flow diverted to Lyman 

Canal. See monthly table for combined flow of river and canal. No flow over Lyman Dam 

spillway this year. Since 1929 spill has occurred only during period Apr. 8 to about 

May 6, 1932, and Apr. 30 to May 13, 1941. Plow completely regulated by many reservoirs 

(combined capacity, 46,900 aere-ft, the largest of which is Lyman Reservoir (capacity, 

31,390 acre-ft). Diversions above station for irrigation of about 8,200 acres, including 1,500 acres served by Lyman Canal. Plow past this station supplemented by spring 

inflow downstream used to irrigate an additional 2,000 acres in vicinity of St. Johns.

350 LITTLE COLORADO RIVER BASIN

Little Colorado River at Hoibrook, Ariz.

Location. Lat 34°53'50", long 110°09'40", In SVf£SW£ see. 6, T. 17 N., R. 21 E., near

right bank on downstream side of bridge on U. S. Highway 260 at Hoibrook, 2j miles

downstream from Puereo River. 

Drainage area. 11,300 sq mi, approximately. 

Records available. March to November 1905, December 1905 to August 1906 (monthly discharge only), September 1906 to April 1907, May 1907 to December 1909 (gage heights

only), September 1949 to September 1954.

Average discharge. 6 years (1905--6, 1949-54), 96.0 cfs (69,500 acre-ft per year). 

Gage. Water-stage recorder. Datum of gage is 5,062.87 ft above mean sea level, datum of

T929. March 1905 to December 1909 staff gage at former highway bridge Just upstream

from present bridge, at different datum. 

Extremes. Maximum discharge during year, 10,800 cfs July 22 (gage height, 8.60 ft); no

flow at times during summer months.

1905-9, 1949-54: Maximum daily discharge, 20,200 cfs Nov. 27, 1905; no flow at

times in most summers.

Peak of flood of Sept. 19, 1923, was computed as 60,000 cfs, from cross section and

slope of water surface by Corps of Engineers, whose studies indicate that this was

probably the greatest flood since 1870. 

Remarks. Records fair except those for periods of ice effect and those for August and

September, which are poor. Discharge.measurements generally'made once a week after

Nov. 19. Diversions above station for irrigation of about 23.000 acres. Some regulation by reservoirs (combined capacity, about 73,000 acre-ft). 

Revisions (water years).--WSP 1313: 1906.

weather records, and comparison with records for related stations.

Note. Result of discharge measurement Apr. 19, 108 cfs; Apr. 26, 17 cfs.

Little Colorado River seepage investigation, Ariz.

The following table gives the results of a seepage investigation on Little Colorado 

River between mile 211.2 at Woodruff, Ariz., and mile 134 as shown on the Little Colorado 

River-profile Survey. These data were obtained to determine Infiltration characteristics 

of the channel, as part of the Investigation conducted by the Ground Water Branch. Gage 

heights at gaging station at Holbrook and on a gage near Winslow show that the variation 

In stage did not exceed 0.02 ft during the period covered by the Investigation.

Drainage area. 137,800 sq mi, approximately.

Records available. October 1922 to September 1954. Prior to 1944, published as Colorado 

River at Bright Angel Creek, near Grand Canyon. Gage-height records collected l|- miles 

downstream, 1908-13, published in reports of U. S. Weather Bureau.

Gage. Two water-stage recorders, one on left bank for ordinary flows since Oct. 1, 1934, 

and one on right bank 700 ft (revised) downstream since Dec. 9, 1922, used for high water 

only, since 1934. Datum of both gages is 2,418.7 ft above mean sea level, preliminary 

datum of 1929.

Average discharge. 32 years (1922-54), 17,390 cfs (12,590,000 acre-ft per year).

Extremes. Maximum discharge during year, 32,800 cfs May 27 (gage height, 15.05 ft); minimum, 3,310 cfs Sept. 8.

1922-54: Maximmm discharge, 127,000 cfs July 2, 1927 (gage height, 29.25 ft); minimum, 700 cfs Dec. 28, 1924 (gage height, -0.70 ft).

Maximum discharge known, 300,000 cfs about July 8, 1884 (computed on basis of flood 

studies at Lees Ferry). Crest discharge of flood of June 19, 1921, 220,000 cfs (gage 

height, 37.5 ft, from floodmarks), from rating curve extended above 120,000 cfs by logarithmic plotting.

Remarks. Records excellent. Discharge measurements generally made once a week and more 

often during high water. Natural flow of stream affected by transmountain diversions, 

storage reservoirs, power developments, ground-water withdrawals and diversions for 

irrigation, and return flow from irrigated areas. Records of chemical analyses, water 

temperatures, and suspended sediment loads for the water year 1954 are given in 

WSP 1353.

Meadow Valley Wash, 65 miles northwest of Overton, and ?J miles southeast of Moapa.

Drainage area. 8.180 sq mi (approximately ), Aof which only about 4,230 sq ml contributes 

directly to surface runoff.

Records available. May 1913 to August 1915, December 1915 to September 1916 (monthly discharge only), December 1947 to September 1952, October 1952 to September 1954 (monthly 

discharge only), discontinued. May 1913 to September 1916 published as "near St. 

Thomas.

Average discharge . 6 years (1948-54), 6.08 cfs.

at different da turns ( sites now submerged by Lake Mead ) .

Ex;;remes..- -Maximum discharge during year, 76 cfs July 26 (gage height, 0.94 ft); no flow 

for many days.

1913-16, 1947-54: Maximum discharge, 6,500 cfs Feb. 22, 1914 (gage height, between 

8 and 9 ft, datum then In use), from rating curve extended above 400 cfs on basis of 

slope-area determination of peak flow; no flow at times in most years.

Highest floods known, 10,000 cfs (estimated) Mar. 3, 1938, and 12,000 cfs (estimated) 

Aug. 11, 1941.

Reraarks . Records fair. Records show flow below Wells Siding diversion dam, including 

overflow from East Canal, which enters river Just below dam. Overflow record amounted 

to about 10 percent of total flow and was estimated on basis of 20 discharge measurements and field estimates. Daily records not sufficiently accurate for publication. 

Many diversions above station for irrigation. Water diverted at dam for irrigation 

downstream or for storage In Bowman Reservoir is not included in this record. Diversions on Apr. 1 were 0.61 cfs in Bowman Reservoir ditch, 9.81 cfs In East Canal, and 

20.3 cfs in West Canal. Considerable waste and drainage return flow enters river below 

station.

, long 114"44"10", in SW, sec. 3, T. 30 N. f R. 23 W., Gila and 

in center of Hoover Dam on Colorado River.

Drainage area. 167,800 sq mi, approximately.

Records available. February 1935 to September 1954. Published as Lake Mead at Boulder Dam 

prior to 1946.

Gage. Water-stage recorder supplemented by indicator read at 12 p.m. daily. Prior to 

Oct. 1, 1952,,daily readings of indicator. Datum of gage is at mean sea level, powerhouse datum, which is datum in use locally and originally based on adjustment of 1912; 

or 0.40 ft above mean sea elvel, datum of 1929, leveling of 1950.

Extremes. Maximum contents during year, 18,384,000 acre-ft Oct. 1 (gage height, 1,157.67

1935-54: Maximum contents, 27.790,000 acre-ft July 29, 30, 1941 (gage height, 

1,220.45 ft); minimum (since 1940), that of Sept. 30, 1954.

Remarks. Reservoir is formed by concrete arch gravity type dam; storage began Feb. 1, 

1935; dam completed Mar. 1, 1936. Total capacity, 31,047,000 acre-ft, consisting of 

the following: Dead storage, 2,620,000 acre-ft below gage height 895.0 ft (gate sills 

in outlet towers); usable contents, 27,207,000 acre-ft between gage heights 895.0 and 

1,221.4 ft (top of automatic spillway gates in raised position); and uncontrolled 

storage, 1,220,000 acre-ft between gage heights 1,221.4 and 1,229.0 ft. Reservoir is 

used to store water for flood control, irrigation, municipal water supply, and power 

development. Figures given herein represent usable contents.

Diversions from Lake Mead. Water is pumped from point 6 miles upstream from Hoover Dam to 

Henderson, Nev., area for municipal and industrial use. Discharge measured by venturi 

meter. Diversion started Apr. 7, 1942. Two pumping plants in the Nevada side of the 

powerplant at Hoover Dam pump water to Boulder City, Nev., for municipal use. Water 

is obtained from penstock and measured by venturi meter. Pumping began March 1932 but 

records available only since October 1935. Records of chemical analyses for the water 

year 1954 are given in WSP 1353.

Cooperation. Records of diversions from Lake Mead furnished by Bureau of Reclamation.

Note. Computed figures of gross evaporation are based on data obtained on Lake Mead by the Bureau 

of Reclamation and at Las Vegas by the Weather Bureau. Record computed by the Geological Survey 

using methods described in Geological Survey Professional Paper 298 {in preparation). Figures of 

gross monthly evaporation, In acre-feet, were determined by dividing the gross monthly evaporation 

in Inches by 12 and multiplying by the surface area of the lake in acres, corresponding to the average water-surface elevation for the month. The average error in the monthly figures of evaporation 

is believed to be approximately 10 percent or less, as compared with approximately 5 percent during 

the comprehensive studies of 1952-53, as reported in Professional Paper 298. "Gross" denotes the 

total evaporation from the lake without deductions for precipitation on the lake surface or for 

natural losses that would have occurred in the area now occupied by the lake.

378 COLORADO RIVER MAIN STEM

Colorado River near Topock, Ariz.

Location. Lat 34"41'15", long 114°27'45", in SW^NWtr sec. 13, T. 15 N., R. 21 W., Gila and 

Salt River meridian, on left- bank in Mohave Canyon, 2.7 miles downstream from Topock, 

39.5 miles upstream from Parker Dam, and 49 miles downstream from Davis Dam.

Drainage area. 172,300 sq mi, approximately. 

Records available. January 1917 to September 1954.

Gage. Water-stage recorder. Datum of gage is 423.02 ft above mean sea level, datum of 

1929. Gage readings have been reduced to elevations above mean sea level. Prior to 

Dec. 3, 1922, at site about 1 mile upstream at different datum. Since May 1, 1939, auxiliary water-stage recorder at former highway bridge at Topock, 2.7 miles upstream from 

base gage at datum 13.33 ft higher.

Average discharge.--17 years (1917-34), 20,260 cfs (14,670,000 acre-ft per year); 20 years 

U934-54), 14,500 cfs (10,500,000 acre-ft per year), unadjusted.

Extremes. Maximum daily discharge during year, 19,700 cfs May 20; maximum elevation,

456.32 ft May 22; minimum daily discharge, 7,660 cfs Oct. 26; minimum elevation, 450.60 

ft Oct. 26.

1917-34: Maximum discharge probably exceeded 200,000 cfs June 22, 1921; minimum, 

1,480 cfs Aug. 17, 1934.

1934-54: Maximum discharge, 35,700 cfs Jan. 29, 1942; minimum, 375 cfs Feb. 14, 

1935; minimum daily, 422 cfs Feb. 14, 1935; maximum elevation, that of May 22, 1954.

Discharge of about 300,000 cfs (based on determination at Lees Perry gaging station) 

occurred about July 10, 1884. Discharge in excess of 400,000 cfs (estimated) probably 

occurred within the period 1857-68 and most likely in 1862.

Remarks. Records excellent. Discharge measurements made twice a month. Many diversions 

above station for irrigation, municipal, and industrial uses. Flow regulated by Lake 

Mead since Feb. 1, 1935, and by Lake Mohave since Jan. 17, 1950.

Revisions (water years). WSP 918: 1921. WSP 1313: 1918(M), 1919(M).

California on Havasu Lake, 1.8 miles upstream from Parker Dam, and 156 miles downstream 

from Hoover Dam.

Records available. January 1939 to September 1954 (monthly record only after October 1942; 

see summary in WSP 1313). Published as supplement to the records for Colorado River below Parker Dam, 1942-50.

Gage..--Venturi meters in pressure lines at intake pumping plant, 

Average discharge. 15 years, 179 cfs (129,600 acre-ft per year).

Extremes. Maximum daily diversion during year, 666 cfs July 23; no diversion Nov. 13-18, 

Jan. 26-28.

1939-54: Maximum daily diversion, 692 cfs Mar. 26, 1939; no diversion for many 

periods.

Remarks. Pumping began Jan. 7, 1939. Figures of monthly diversion shown represent water 

pumped less return surface flow from Gene and Copper Basin Reservoirs. No water returned as surface flow from either reservoir since 1941 except on Nov. 16, 17, 1953, 

when 910 acre-ft were returned from Gene Reservoir to Havasu Lake. During this year 

1,499 acre-ft of cooling water, which is included in the record of diversions, was returned to the lake at the pumping plant. Percolation from Gene and Copper Basin Reservoirs was measured in 4 washes between pumping plant and Copper Basin'Wash by means of 

weirs, each about 1 mile from Colorado River. Percolation amounted to 5,110 acre-ft 

during water year, and was not subtracted from the diversion record.

Cooperation. Records furnished by Metropolitan Water District of Southern California.

but not in Lake Mead and Lake Mohave.

Extremes. Maximum discharge during year, 20,300 cfs Sept. 5 (gage height, 21.78 ft); 

minimum daily, 8,150 cfs Nov. 7; minimum gage height, 17.01 ft Dec. 3.

1934-54: Maximum discharge, 42,400 cfs Feb. 8, 1937; no flow at Parker Dam parts of 

several days in 1942 when gates in dam were closed; minimum daily, 1,440 cfs Feb. 15, 

1935.

An unregulated discharge of probably less than 1,350 cfs occurred Aug. 18, 1934 

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

Remarks. Records excellent. Discharge measurements generally made three times a month. 

Many diversions above station. Flow regulated by Lake Mead since Feb. 1, 1935, Lake 

Mohave since Jan. 17, 1950, and by Havasu Lake since July 1, 1936. For record of

auxiliary recorder half a mile downstream.

Remarks. Records good except those for periods of doubtful record of gate openings, which 

are poor. Figures given herein represent flow diverted from Colorado' River for irrigation of 67,460' acres. Discharge measurements generally made twice a month. Regulatory return flow from spillway basin about 500 ft downstream from intake gates has been 

subtracted from these records. There is appreciable unmeasured return flow from six 

wasteways extending throughout the project and from Outfall drain which has not been 

subtracted.

sec. 30, T. 6 S., R. 21 W., Gila and Salt River meridian. The dam is 5 miles upstream 

from Laguna Dam, 15 miles northeast of Yuma, 90 miles downstream from intake of Palo 

Verde Canal, and 147 miles downstream from Parker Dam.

Drainage area. 184,600 sq mi, approximately.

Records available. 1903-34 (yearly discharge only), July 1934 to September 1954 (monthly 

discharge only since October 1942). Published as "near Picacho, Calif.," prior to 1943.

Sage. No gage on river at this site. Discharge figures published herewith are based on 

combined daily records of discharge obtained at gaging station on Colorado River at 

Yuma, Ail-American Canal near Imperial Dam. Gila Gravity Main Canal at Imperial Dam, 

and North Gila Valley Canal at Laguna Dam (estimated), less that of Gila River near 

Dome. Drainage and waste return flows and channel losses between these stations and 

Imperial Dam have been neglected. Prior to October 1942, water-stage recorder at site 

14f miles upstream at datum 167.38 ft above mean sea level, datum of 1929.

Average discharge.--20 years (1934-54), 13,490 cfs (9,766,000 acre-ft per year).

Extremes. Maximum daily discharge during year, 17,400 cfs May 25; minimum daily, 8,080 cfs

1934-54: Maximum discharge, 40,800 cfs Sept. 5, 1939; minimum, 538 cfs Aug. 3, 1934; 

minimum daily discharge since regulation of Hoover Dam began, 1,450 cfs Feb. 17, 1935.

Remarks. Records show flow of Colorado River reaching Imperial Dam, which is above all 

diversions in vicinity of Yuma. Many diversions from Colorado River and tributaries upstream. Flow regulated by many reservoirs, principally Lake Mead, since 1935.

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

Location. Duncan Valley lies along Gila River in Hidalgo County, N. Mex., and Greenlee 

County, 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. Nine 

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

and several pumps have rights to divert water from Gila River for irrigation in the 

valley. The first three canals listed divert in New Mexico, and the others divert in 

Arizona. Intake of Sunset Canal, at eastern end of valley, is 6 miles downstream from 

station on Gila River below Blue Creek, near Virden, N. Mex. Intake of York Canal at 

western end is about 14 miles upstream from station on Gila River near Clifton, Ariz.

Records available. January 1936 to September 1954 (combined monthly diversions and annual 

diversions by each canal). See WSP 1313 for summary of records of each canal (some 

since 1914) prior to 1951. Records of daily discharge for Sunset and New Model Canals 

published elsewhere in this report.

Ga ge. Water-stage recorders and Parshall flumes on canals, and rated pumps for pumped 

water.

Remarks. Record shows total diversions, unadjusted for return flows. Water obtained by 

pumping from ground water for irrigation in the valley is not included in these records. 

Decreed area for irrigation for the valley is 8,061 acres, of which 6,300 acres were 

irrigated during 1954.

Cooperation. All records except those for Sunset and New Model Canals furnished by Gila 

water Commissioner. Combined monthly diversions compiled by Gila Water Commissioner 

and Geological Survey.

CILA RIVER BASIN 401

Eagle Creek near Double Circle Ranch, near Morenci, Ariz.

Location. Lat 33°18'00", long 109°29'30", in SE£ sec. 32, T. 1 S., R. 28 E., unsurveyed, 

on left bank half a mile upstream from head of box canyon 2f miles downstream from 

Willow Creek, 3t miles downstream from Double Circle Ranch, and 17 miles northwest of 

Morenci.

Drainage area. 377 sq mi.

Records available. August 1944 to September 1954.

Gage. Water-stage recorder. Altitude of gage is 4,722 ft (by barometer). Prior to 

Jan. 13, 1952, at datum 2.01 ft higher.

Average discharge. 10 years, 21.6 cfs (15,640 a ere-ft per year).

Extremes. Maximum discharge during year, 4,380 cfs Aug. 24 (gage height, 7.15 ft), from 

rating curve extended above 80 cfs on basis of slope-area determination at gage height 

8.51 ft; minimum, 2.0 cfs Dec. 25, result of freezeup.

1944-54: Maximum discharge, 7,000 cfs Jan. 13, 1952 (gage height, 8.51 ft), from 

rating curve extended above 170 cfs on basis of slope-area determination of peak flow; 

minimum, 1.5 cfs Sept. 5, 1951.

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

good, and those above 25 cfs during July and August, which are fair. Diversions above 

station for irrigation of about 500 acres; negligible diversion to one ditch between 

mouth of Willow Creek and this station. Water pumped from Black River into Eagle Creek 

basin 25 miles upstream is an appreciable part of flow past this station (see p. 398). 

Inflow between station and point 2£ miles downstream, below Sheep Wash, as determined 

by discharge measurements, was 4.7 cfs Mar. 16, 6.5 cfs May 26, and 4.6 cfs on July 16. 

Discharge measurements or estimates of the combined flow of Eagle Creek 900 ft above 

Willow Creek and of Double Circle ditch, in cubic feet per second, for the water year 

1954, are given as follows:

a No gage-height record; discharge estimated on basis of records for station above pumping plant, 

near Morenci, and Willow Creek near Double Circle Ranch, near Morenci.
402 GILA RIVER BASIN 

Eagle Creek above pumping plant, near Morenci, Ariz,

Location. Lat 33°04'00", long 109°26'45", in SE&iEi sec. 22, T. 4 S., R. 28 E., on right 

bank Z\ miles upstream from Phelps Dodge Corp. pumping plant, 5 miles west of Morenci, 

and 13 miles upstream from mouth.

Drainage area. 613 sq mi.

Records available. April 1944 to September 1954.

Gage. Water-stage recorder, Parshall flume and weir. Altitude of gage is 3,650 ft (from 

' topographic map). Supplementary water-stage recorder 80 ft upstream at datum of 

Parshall flume. Prior to Nov. 15, 1952, supplementary water-stage recorder at site 

75 ft downstream at different datum.

Average discharge. 10 years, 31.6 cfs (22,880 acre-ft per year).

Extremes.--Maximum discharge during year, 4,930 efs July 22 (gage height, 6.95 ft, at supplementary gage), from rating curve extended above 3,900 cfs by logrithmic plotting; 

minimum, 6.8 cfs Dee. 24, result of freezeup.

1944-54: Maximum discharge, 5,340 efs Jan. 14, 1952 (gage height, 10.6 ft, at 

former supplementary gage and datum then in use), from rating curve extended above 

1,700 cfs by logarithmic plotting; minimum, 3.2 cfs July 1, 1946.

A discharge of 13,000 cfs (by slope-area determination of peak flow) occurred 

Feb. 10, 1932, at a stage of 11 ft above normal low water at footbridge 2^ miles downstream; the stage of flood of Sept. 26, 1944, was about 2.5 ft lower at same site.

Remarks. Records excellent except those above 100 cfs, which are fair. Diversions above 

station for irrigation of about 500 acres, mostly above Willow Creek. Water from 

Black River was pumped into Eagle Creek basin, 5li miles upstream from this station, 

for about three-quarters of the year (see p. 398). Diversions by pumping for mining, 

metallurgical treatment or ore, and domestic use in and near Morenei and Clifton are 

made from Eagle Creek, 2^ miles downstream from this station, and from San Francisco 

River near Clifton. The monthly quantities diverted are shown in table below. 

Slightly less than 96 percent of the pumpage was from Eagle Creek.

404 GILA RIVER BASIN

Diversions from Gila River in Safford Valley, Ariz.

Location. Safford Valley lies along Gila River in Graham County, Ariz., extending from 

vicinity of Bonita 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 upper 

end of the valley, is 0.6 mile upstream from station on Gila River near Solomon. Intake of Colvin-Jones Canal, at the lower end, is 25.8 miles upstream from station at 

Calva. Record of canals obtained below wasteways used for regulation.

Records available. 1936-54 (records of combined monthly diversions in Safford Valley, 

and annual diversions by each canal); records of monthly diversion 1914-15 and records 

of monthly and daily diversion, 1920-31 for all canals except Colvin-Jones; records 

for Brown Canal also for water year 1931-32. Tidwell Canal was published as Michelana 

Canal in records for 1914-15 and 1920-31.

Gages. Water-stage recorders and Parshall flumes on canals and rated pump.

Remarks. Figures shown are total diversions unadjusted for return flows. Decreed area 

for irrigation in Safford Valley is 32,512 acres and water was issued this year for 

entire acreage. Water obtained by pumping from ground water for irrigation in the 

valley is not included.

Cooperation. Records furnished by Gila Water Commissioner.

or yearly mean discharges, 10.7 cfs.

Extremes. Maximum discharge during year, 6,980 cfs Sept. 12 (gage height, 14.20 ft); no 

flow for many days.

1931-54: Maximum discharge, 27,500 cfs Aug. 9, 1931 (gage height, 19.0 ft), by 

slope-area determination of peak flow; no flow for many days in each year.

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

Records do not include waste water passing station from San Jose Canal, which diverts 

from Gila River. Diversions above station for irrigation of about 1,600 acres, mostly 

by pumping from ground water.

Some regulation of flood flows prior to failure of dam Aug. 11, 1954, on floodcontrol detention reservoir located 35 miles upstream in sees. 22, 23, 27, T. US.,

Published as "at San Carlos" 1899-1911, as "near San Carlos" 1914-26, and as at Coolidge 

Dam" 1927-28.

Gage. Water-stage recorder and Parshall flume. Datum of gage is 2,309.33 ft above mean 

sea level, datum of 1929. Prior to Feb. 5, 1911, staff or chain gages at various sites 

and datums above mouth of San Carlos River. Apr. 29, 1914, to Mar. 8, 1937, water-stage 

recorder at various sites within 1 mile upstream from present site at different datum.

Average discharge. 42 years (1901, 1904, 1914-54), 383 cfs (277,300 acre-ft per year);

 median of yearly mean discharges, 245 cfs (adjusted for storage in San Carlos Reservoir).

Extremes. Maximum discharge during year, 545 cfs June 24 (head on flume, 2.67 ft); minimum 

daily, 0.6 cfs for many days during October, November, and December.

1914-54: Maximum discharge, 130,000 cfs Jan. 20, 1916, estimated on basis of peak 

discharge near Solomon and at Kelvin; no flow for several periods. Maximum discharge 

since completion of Coolidge Dam,1,350 cfs July 28, 1952 (head on flume, 4.64 ft).

Remarks. Records excellent except those below 5 cfs, which are fair. Discharge measure-

 ments generally made three times a month. Large diversions above San Carlos Reservoir 

for Irrigation, metallurgical treatment of ore, and municipal supply. About 55,500 

acres of land were irrigated, a considerable portion by pumping from ground water. Flow 

regulated by San Carlos Reservoir at Coolidge Dam since Nov. 15, 1928 (see preceding

bank 15- miles north of Winkelman, 2 miles upstream from San Pedro River, and 29 miles

downstream from Coolidge Dam.

Drainage area . --13 . 268 sq mi, of which 382 sq mi is below Coolidge Dam. 

Records available . September 1917 to June 1918, September 1941 to September 1954. 

Gage . Water-stage recorder. Datum of gage is 1,920.95 ft above mean sea level, datum of

1929, supplementary adjustment of 1949. Prior to Sept. 10, 1941, chain gage at bridge

1.5 miles downstream at different datum. 

Average discharge . 13 years (1941-54), 181 cfs (131,000 acre-ft per year); median of

yearly mean discharges, 117 cfs, all adjusted for storage in San Carlos Reservoir. 

Extremes . Maximum discharge during year, 51,700 cfs Aug. 5 (gage height, 17.89 ft), from

rating curve extended above 2,200 cfs on basis of slope-area determination of discharge

at 55,000 cfs; no flow parts of Oct. 4, 5, 6.

1941-54: Maximum discharge, 55,000 cfs, 500 cfs of which was released at Coolidge

Dam, Aug. 9, 1944 (gage height, 18.40 ft), from rating curve extended above 2,900 cfs

on basis of slope-area determination of peak flow; no flow parts of June, July, and

August, 1947, June and July 1951. 

Remarks . Records good. Large diversions above station for irrigation, metallurgical

treatment of ore, and municipal supply, but none between Coolidge Dam and this station.

About 55,500 acres irrigated in the basin above Coolidge Dam, a considerable portion by

pumping from ground water. Flow regulated by San Carlos Reservoir (see p. 408). Discharge measurements generally made once a month October to Februrary and three times

a month March to September.

Location. Lat 33°06'10", long 110°58'45", in NW£NW£ sec. 12, T. 4 S., R. 13 E., on left 

bank at Kelvin, 1,000 ft downstream from Mineral Creek, 17 miles downstream from 

San Pedro River, and 19^ miles upstream from Ashurst-Hayden Dam.

Drainage area. 18,011 sq mi, of which 5,125 sq mi is Below Coolidge Dam. 

Records available. January 1911 to September 1954.

Gage. Water-stage recorder at present site June 15 to Nov. 30, 1914, and since Sept. 1, 

1915. Datum of gage is 1,743.22 ft above mean sea level, datum of 1929, supplementary adjustment of 1949. Prior to June 15, 1914, and Dec. 1, 1914, to Aug. 31, 1915, 

staff gages at several sites within 2 miles of present site at different datums. 

Supplementary recorder 900 ft up.streara since May 27, 1951.

Average discharge. 43 years (1911-54), 515 cfs (372,800 acre-ft per year); median of 

yearly mean discharges, 360 cfs (adjusted for storage in San Carlos Reservoir).

Extremes. Maximum discharge during year, 17,800 cfs Aug. 5 (gage height, 13.07 ft); minimum daily, 1.2 cfs for several days in October.

GILA RIVER BASIN 415

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

Location. Lat 33°06'00", long 111°14'50", in SW^NWi sec. 8, T. 4 S., R. 11 K. , on left 

bank at Ashurst-Hayden Dam 9 miles northeast of Florence.

Drainage area. 18,305 sq mi.

Records available . July 1923 to September 1954 (head on crest of dam only). Records of 

monthly diversions to Florence-Casa Grande Canal available January 1928 to September 

1954.

Gage . Water-stage recorder. Permanent crest of dam is 1,562.6 ft above mean sea level,

"datum of 1929. Crest height during year varied from 1.53 to 1.76 ft higher prior to 

Aug. 4, 1954, and was 1.10 ft higher thereafter by use of flashboards. Prior to Apr. 12, 

1932, chain gage at same site and datum. Water-stage recorder and Parshall flume on 

Florence-Casa Grande Canal, 2.6 miles downstream at China Wash, to obtain record of 

diversion. Prior to Jan. 12, 1937, water-stage recorder 900 ft downstream from AshurstHayden Dam.

Extremes . Maximum head on dam during year, 3.7 ft Aug. 19 (by observation); no flow over 

dam greater part of year.

1923-54: Maximum head on dam, 8.0 ft Sept. 28, 1926; no flow over dam greater part 

of each year.

Remarks. Records show dally 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. Florence-Casa Grande Canal diverts water at dam supplemented by 

pumping from ground water for irrigation of land under 100,000-acre San Carlos project. 

Canal records adjusted for intervening sluicing and pumping (but not natural losses), 

to show water available at dam, except for flow through dam or passed over dam during 

times of flood runoff. Flow regulated by San Carlos Reservoir. Diversions above 

station for irrigation of about 60,000 acres, a considerable portion of which are 

irrigated by pumping from ground water.

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

 in Spanish land grant of Buena Vista, on left bank three-quarters of a mile downstream 

from international boundary, 5i miles upstream from Yerba Buena dam site, and 65 miles 

east of Nogales.

Drainage area. 533 sq mi, of which 348 sq mi is in Mexico.

Records available. March to November 1907 and April 1909 to December 1912 (discharge meas-

 urements and rragmentary gage-height record), January 1913 to June 1922 (October 1915 

to September 1916 monthly and annual discharge only), May 1930 to December 1933, July 

1935 to September 1954. Water year figures of runoff for 1913, 1915-16, 1920-22, 1930, 

1934-35 published herewith for first time.

Gage. Water-stage recorder since June 3, 1930. Datum of gage is 3,702.54 ft above mean

~sea level, datum of 1929 (levels by International Boundary and Water Commission). Prior 

to June 30, 1922, staff gages and water-stage recorders at various sites 5 to 6 miles 

downstream at different datums. .

Average discharge. 35 years (1912-22, 1929-54), 20.3 cfs (14,700 acre-ft per year); median 

of yearly mean discharges, 16.0 cfs. .

Extremes. Maximum discharge during year, 10,600 cfs July 10 (gage height, 13.27 ft), from

 rating curve extended above 1,800 cfs on basis of slope-area determination of peak flow;

n° 1930-54?6 Maximum discharge, 12 ,000 cfs Aug. 31, 1935 (gage height, 12.3 ft), from 

rating curve extended above 2,300 cfs on basis of slope-area determinations at gage 

heights 9.5 and 10.9 ft; maximum gage height, that of July 10, 1954; no flow for several 

days or parts of days in most years.

Flood of Dee. 22, 1914, which is greatest known at Tucson, Ariz., probably exceeded 

that of Aug. 31, 1935, at this station, but stage was not accurately determined. 

Remarks Records good. Irrigated area above station comprises about 2,500 acres, all but

In San Carlos Indian Reservation, on left bank 1 mile downstream from Phelps Dodge 

Corp. pumping plant, 1^ miles downstream from Freezeout Creek, 7 miles northwest of 

Point of Pines, and 63 miles upstream from confluence with White River.

Drainage area. 560 sq mi.

Records available. June 1953 to September 1954.

Gage. Water-stage recorder. Altitude of gage Is 5,742 ft (from river-profile map).

Extremes. 1953: Maximum discharge during period June to September, 140 cfs July 26 

(gage height, 3.56 ft); minimum, 7.0 cfs Sept. 11, 12.

1953-54: Maximum discharge during water year, 5,000 cfs Mar. 23 (gage height, 9.35 

ft), from rating curve extended above 540 cfs on basis of slope-area determination of 

peak flow; minimum, 3.5 cfs Dec. 7, result of freezeup.

Remarks. Records good except those for periods of Ice effect, which are fair. Water Is 

diverted at pumping plant 1 mile upstream and pumped into headwaters of Willow Creek 

(tributary of Eagle Creek) for mining, metallurgical treatment of ores, and domestic 

supply In vicinity of Morencl (see records for Willow Creek diversion from Black River, 

near Morencl). Combined flow of river and diversion Is shown in monthly tables given 

herein.

flow most of year.

1953-54: Maximum discharge, that of June 9, 10, 1954, no flow for many days.

Remarks.--Records excellent. Entire flow consists of water pumped from Lake Show Low in 

Little Colorado River basin, into headwaters of Forestdale Creek in Salt River basin.

Lake Show Low.--A lake on Show Low Creek, tributary of Little Colorado River, formed by 

Jaques Dam in NWt sec. 10, T. 9 N., R. 22 E., 4f miles southeast of Show Low; dam completed and storage began in spring of 1953. Total capacity, 6,176 acre-ft, consisting 

of 1,070 acre-ft dead storage below elevation 6,535.0 ft (sill of outlet structure) 

and 5,106 acre-ft usable storage between elevations 6,535.0 and 6,570.0 ft (sill of 

overflow spillway). Capacity table prepared by Leeds, Hill, and Jewett, consulting 

engineers, from surveys by the firm. Water cannot be pumped when lake elevation is below 6,538.5 ft ( sill of intake to pumping plant), but can be released to river channel 

down to elevation 6,535.0 ft. The following table shows elevations, in feet, and usable 

contents, in acre-feet. Elevations Mar. 31 to Aug. 31 furnished by Navapache Electric

capacity of the four reservoirs is 1,755,000 acre-ft, divided as follows: Roosevelt 

Lake, 1,382,000 acre-ft; Apache Lake, 245,000 acre-ft; Canyon Lake, 58,000 acre-ft; 

Sahuaro Lake, 70,000 acre-ft. Dams forming these reservoirs were built as follows: 

Roosevelt 1905-11; Horse Mesa 1924-27; Mormon Plat 1923-25; Stewart Mountain 1928-30. 

The four dams forming these reservoirs completely develop the fall in Salt River from 

Roosevelt Lake to Stewart Mountain Dam. Elevation of water surface varies from 1,422.0 

ft, sill of lowest outlet in Stewart Mountain Dam, to 2,136 ft, top of spillway gates 

in raised position on Roosevelt Dam. Since 1910, spill over Roosevelt Dam because of 

capacity storage has occurred only during the following periods: Apr. 15 to June 21, 

1915, Jan. 19 to May 30, 1916, Apr. 21 to June 7, 1917, Feb. 17 to June 3, 1920, 

Apr. 13 to July 24, 1941. Water from this system is used for irrigation of Salt River 

Valley and for generation of power.

Cooperation. Records of daily contents furnished by Salt River Valley Water Users' Association.

Location. La t 34«22'05", long 111 "39 '55", In NEfcSW^ sec. 20, T. ll£ N. , R. 7 E. , at head 

of Stehr Lake, 2f miles northeast of Chllds powerplant, 4.4 miles by flume downstream 

from Irvlng powerplant, and 17-J miles southeast 'of Camp Verde.

Records available. January 1952 to September 1954.

. Hater-stage recorder and weir In concrete flume, 

from topographic map).

Altitude of gage Is 3,730 ft

Extremes. Maximum dally discharge during year, 50 cfs Apr. 4, 5; no flow Dec. 4-6.

1952-54: Maximum dally discharge, 51 cfs Apr. 17-21, 1952; no flow Aug. 13, 14, 

1952, Dec. 4-6, 1953.

Remarks. Records good. Record Is obtained at head of Stehr Lake, a regulatory basin, and 

shows the water used by Childs powerplant. Most of flow originates at Fossil Springs 

which are fairly constant. Diversion is made from Fossil Creek 8 miles upstream from 

this station and is first used by Irving powerplant. A secondary diversion from Fossil 

Creek enters flume below Irving plant and was measured as follows: Oct. 29, 0.11 cfs; 

Jan. 21, 0.72 cfs; Apr. 27, 0.74 efs; May 20, 0.43 cfs; June 23, 0.19 cfs; July 28, 

0.35 cfs; Aug. 27, 0.34 cfs; Sept. 28, 0.26 cfs. Based on these measurements, observations of flow In Fossil Creek below Irving, and records for previous years, flow 

through Irving powerplant is estimated as about 98 percent of record published herewith.

Extremes . Maximum discharge during year, 19,700 cfs Mar. 23 (gage height, 13.59 ft); minimum, 64 cfs June 20, 21 (gage height, 1.42 ft), caused by power regulation on Fossil 

Creek.

1945-54: Maximum discharge, 81,600 efs Dec. 31, 1951 (gage height, 17.62 ft), from 

rating curve extended above 42,000 cfs by logarithmic plotting; minimum, 52 cfs 

July 10, 1951 (gage height, 1.25 ft).

Greatest flood since 1924 occurred Mar. 3, 1938, discharge, 100,000 cfs (gage 

height, 19.0 ft, from floodmarks), computed from comparison of peak discharge at other 

stations on Verde River.

Remarks . Records excellent. Diversions above station for irrigation of about 12,500

acres, some of which is by pumping from ground water. Discharge measurements generally 

made twice a month. Low flow slightly regulated by powerplant 32 miles above station, 

using water from Fossil Creek. This station is above all major reservoirs on Verde 

River.

 Dams on Verde River. Horseshoe Reservoir, formed by Horseshoe Dam, lat 33°59'15 , long 

111*42'45", in sec. 2, T. 7 N., R. 6 E., unsurveyed; and Bartlett Reservoir, formed by 

Bartlett Dam, lat 33°49', long lll^S', in sec. 34, T. 6 N., R. 7 E., unsurveyed.

Drainage area. 6,185 sq mi at Bartlett Dam.

Records available. July 1939 to September 1954. 

Reservoir at Bartlett Dam.

Prior to 1946, published as Bartlett

s. Water-stage recorders on dam structures. Datum of gage on Horseshoe Reservoir is 

7900.00 ft and on Bartlett Reservoir 1,609.46 ft above mean sea level, datum of 1929.

Extremes. Maximum contents during year, 165,400 acre-ft Apr. 4; minimum, 6,320 acre-ft

1939:54: Maximum contents, 310,100 acre-ft May 2, 1952; no storage at times when 

natural flow of river was passed through reservoir system.

Remarks. Horseshoe Reservoir is formed by earth- and rocle-flll dam; dam completed and 

 storage began Nov. 15, 1945. Bartlett Reservoir is formed by concrete multiple-arch 

dam; dam completed May 1939 and storage began Feb. 5, 1939. Total capacity of the two 

reservoirs is 322,300 acre-ft divided as follows: Horseshoe Reservoir, 142,800 acre-ft 

between elevation 1,915.0 ft (sill of outlet gage) and 2,026.0 ft (top of spillway 

gates); tfartlett Reservoir, 179,500 acre-ft between elevation 1,619.46 ft (10 ft above

location. Lat 34°19', long 112*04', in NW&El sec. 20, T. 11 N., R. 3 E., on left bamc at 

Sycamore dam site, 700 ft downstream from Big'bug Creek and 12 miles southeast of Mayor.

Drainage area. 588 sq mi.

Records available. January 1940 to September 1954.

Gage. Water-stage recorder. Datum of gage is 3,434 ft (levels by Marioopa County Municipal Water Conservation District No. 1).

Average discharge. 14 years, 15.2 cfs (11,000 aore-ft per year).

Extremes. Maximum discharge during year, 4,570 cfs Sept. 3 (gage height, 7.22 ft); minimum daily discharge, 0.1 cfs June 13-15.

1940-54: Maximum discharge, 13,000 efs Mar. 1, 1941 (gage height, 11.97 ft), from 

rating curve extended above 1,600 efs on basis of slope-area determination of peak fl 

flow; negligible flow at times during the summer months in most years lihen. entire flow 

was diverted to Perry Canal above station, and flow past gage was seepage only.

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

which are poor. Diversions above station for mining and irrigation of about 600 acres. 

Water diverted just above station to Perry Canal.

Extremes. Maximum discharge over dam during year, 1,760 cfs Aug. 12 (gage height, 5.64 

ft); no flow most of year.

1921-54: Maximum discharge observed, 85,000 cfs Dec. 28, 1923 (gage height, 11.0 

ft, present datum); no flow for extended periods each year.

Maximum discharge known, 250,000 cfs (estimated) in February 1891.

Remarks. River records good except those for period of sluice (Aug. 24), which is poor. 

Records include flow over crest and through sluice gates of Gillespie Dam but do not 

include flow in Gila Bend and Enterprise Canals which divert from river immediately 

above dam. Other large diversions above station for Irrigation. Flow of Gila River 

and tributaries above this station is regulated by San Carlos Reservoir on Gila River 

(capacity, 1,205,000 acre-ft); by a series of reservoirs on Salt River (capacity, 

1,755,000 acre-ft); by Bartlett and Horseshoe Reservoirs on Verde River (capacity, 

322,300 acre-ft); and by Lake Pleasant on Agua Fria River (capacity, 163,800 acre-ft).

For records of combined flow of Gila River, Gila Bend Canal and Enterprise Canal, 

published as Gila River above diversions at Gillespie Dam, and for monthly records of 

Gila Bend Canal and Enterprise Canal, see tables on following page. Records for chemical analyses and water temperatures for the water year 1954 are given in WSP 1353.

Remarks. Records excellent. Many diversions from Colorado River and tributaries. Prin- 

 cTpal diversions below Parker Dam are Colorado River Indian Reservation Canal, Palo 

Verde Canal, All-American Canal, Gila Gravity Main Canal, and North Gila Valley Canal. 

Return flows entering downstream but above northerly international boundary are Yuma 

Main Canal wasteway, California drain, Araz drain, and Pilot Knob wasteway. See 

monthly table below for combined flow of river, Yuma Main Canal wasteway, and California drainage canal. Plow of Colorado River regulated by Hoover, Davis, Parker, Headgate Rock, and to a small extent by Imperial and Laguna Dams. No regulation on Gila 

River below Gillespie Dam. Discharge measurements generally made three times a week.

Bernardino meridian, on right bank at downstream end of powerplant, 500 ft from turnout in All-Amerlcan Canal to Yuma Main Canal, 4 miles north of Yuma, and 14i miles 

downstream from Intake of All-Amerlcan Canal at Imperial Dam.

Records available. July 1926 to September 1954 (prior To October 1938 monthly discharge 

only published in WSP 0.313). Diversions from All-Amerlcan Canal and Yuma Main Canal 

above siphon-drop powerplant, October 1947 to September 1954 (monthly discharge only). 

Diversions from Yuma Main Canal between siphon-drop powerplant and Yuma Main Canal 

Canal wasteway^ October 1940 to September 1954 tnonthly discharge only; prior to 

lOclofier 1947 published In WSP 1313).

. Differential recorder^ to record head on turbines of powerplant. Normal operating 

evel of forebay at ft>ow«rglant is 151.0 ft above mean sea level, datum of 1929,or 150 3 

ft above mean sea level, Yums project datum. Prior to Oct. 30, 1938, floating staff 

gases on tallrace and in atilling well connected to forebay. Oct. 30, 1938, to Mar. 1, 

1945, water-stage recorder on tallrace and floating staff gage on forebay stilling 

well, and Mar. 2, 1945, to Jan. 11, 1951, water-stage recorders on tallrace and forebay tilling well.

;e discharge.--28 years, 1,721 cfs.

j.y, 1,360 cfo Peb. 15. 

1930-54: Maximum dally discharge, 2,040 cfs Nov. 11, 1943; no flow for some days in

Remarks.-- flecords excellent. Dally discharge determined from flow through turbines, computed from relation between discharge, head, and gate openings as logged by powerplant 

operators. Bypass discharge through waste gates is Included in record. Rating of 

turbines checked by two or more discharge, measurements a month. Flow regulated by 

gates from Ail-American Canal. Records show quantity of water diverted from All- 

.tawican, Canal to Yuma Main Canal, except that diverted from forebay of powerplant to 

Walapai Canal. Bie water not 'needed for Irrigation on Yuma project Is returned to 

Colorado River through Yuma Main Canal wasteway,,\3|jnileB downstream.

The combined diversions by several small canals from the All-American Canal and by 

walapal Canal from Yuma Main Canal, above the powerplant, and the combined diversions 

by several small canals from the Yuma Main Canal between siphon-drop powerplant and 

Yuma Main Canal wasteway are shown in the monthly table below. These diversions used 

to Irrigate about 10,800 acres on the Bard and Indian Units of the Reservation Division of the Yuma project In California.

Yuma Main Canal wasteway at Yuma , Arlz .

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

 TaT~32 044'00", long 114°37'20", in SWfeE^ sec. 26, T. 16 S., R. 22 E., San Bernardino 

meridian, 1,646 ft upstream from intake of Colorado River siphon on Yuma Main Canal,

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

Yuma Main Canal. The wadteway discharges into Colorado River in SW£ sec. 26, T. 16 

R. 22 E. , half a mile downstream from station on Colorado River at Yuma.

S.,

Records available . -April 1913 to September 1964 (prior to October 1930, monthly discharge 

only, published in WSP 1313).

Average discharge. -26 years (1928-54), 1,264 cfs.

Extremes . -Maximum daily discharge during year, 1,910 cfs nov. 17, Dec. 3; minimum daily, 

 SWcfs Mar. 9.

1930-64; Maximum daily discharge, 2,020 cfs Dec. 24, 25, 1948; no flow for several 

days in 1937-39, 1946, 1950.

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

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

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

Records do not include flow of California drainage canal which discharges into the 

wasteway a quarter of a mile above its mouth.

Cooperation . -Record of small irrigation diversions between Yuma Main Canal at siphondrop powerplant and Yuma Main Canal below Colorado River siphon furnished by Bureau 

of Reclamation.

DIVERSIONS AND RETURN FLOWS AT AND BELOW IMPERIAL DAM 463

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

Location. Two gages, one at each end of canal siphon passing under Colorado River. At

 intake, lat 32°43'50", long 114°37'10", in SW^S'Ei sec. 26, T. 16 S., R. 22 E., San 

Bernardino meridian, on left bank in California, 1,645 ft downstream from center of 

Yuma Main Canal wasteway gates, and 3£ miles downstream from siphon-drop power-plant. 

At outlet, in NW^NE^ sec. 35, T. 16 S., R. 22 E., San Bernardino meridian, on right 

bank in Arizona. Both gages are a quarter of a mile downstream from highway bridge 

over Colorado River at Yuma.

Records available. January 1924 to September 1954 (prior to October 1938, monthly discharge only published in WSP 1313). Diversion from Yuma Main Canal for municipal 

supply for Yuma, October 1947 to September 1954 (monthly discharge only).

Gage. Water-stage recorder at each end of siphon. Datum of each gage is 100.03 ft above 

mean sea level, Yuma project datum, or 100.57 ft, datum of 1929. Elevation of sill of 

inlet is 125.5 ft above mean sea level, datum of 1929. Prior to Oct 29, 1938, staff 

gages at approximately same sites, read simultaneously.

Average discharge. 30 years, 480 cfs.

Extremes. Maximum daily discharge during year, 793 cfs July 30; minimum daily, 10 cfs fTov7~16-17.

1930-54: Maximum daily discharge, 882 cfs Aug. 15, 1952; no flow during short periods In most years.

Remarks. Records excellent except those between 100 and 200 cfs, which are good, and 

those below 100 cfs, which are poor. Daily discharge computed from relation between 

discharge and head on siphon, which is the difference between intake and outlet gages. 

Discharge measurements made every two weeks. Records show quantity of water delivered 

through Colorado River siphon for irrigation of about 45,500 acres in the Valley Division of the Yuma project and fer supplementary municipal supply for city of Yuma. Records of chemical analyses for the water year 1954 are given in WSP 1353.

Cooperation. Records of diversion for supplementary municipal supply for city of Yuma 

furnished by Arizona Public Service Co.

Discharge., In cubic feet per second, water year October 1953 to September 1954

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

The Yuma project consists of the Reservation Division In California operated by the 

Bureau of Reclamation and the Valley Division in Arizona operated by the Yuma County Water 

Users' Association. Water is obtained from the Colorado River at Imperial Dam through the 

Ail-American and Yuma Main Canals. See records of Yuma Main Canal at siphon-drop powerplant and below Colorado River siphon.

The California drainage canal and Araz drain in the Reservation Division and the Cooper, 

Eleven-Mile, and Twenty-one Mile wasteways in the Valley Division return surface flows to 

the Colorado River. Water collected by the Main drain and East Main Canal in the Valley 

Division is delivered across the international boundary for use in Mexico. None of this 

water is included in the record of the Colorado River at Yuma.

468 MISCELLANEOUS DISCHARGE MEASUREMENTS

Measurements of streamflow In the Colorado River basin made at points other than regular 

gaging stations are given In the following table. Most of these measurements were made during periods of base flow when streamflow is primarily from ground-water storage. These 

measurements when correlated with the simultaneous discharge of a nearby stream where continuous records are available will give a picture of the low-flow potentiality of stream. 

For many sites measurements have been made in other years.

Determinations of peak flow at points other than regular gaging stations are given in a 

separate table on page 472.
