SCOPE OP 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, 1953. 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 12,800 gaging stations in the 48 States and at many others in the Territories of Alaska and Hawaii. On September 30, 1953, 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 1953 water year, most of 

which are published at the end of this report.

DEFINITION OF TERMS AND ABBREVIATIONS

The terms of streamflow and other hydrologic 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 p^r 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 runoff 

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.

WSF^ 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 

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

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 OF 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 1953 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 

watei? 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). 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
6 SURFACE WATER SUPPLY, 1953, PART 9

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 infromation 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 values for the maximum day and the minimum day for 

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

day of its occurrence.

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

the daily values; it is, the total cfs-days for the month. The line headed "Mean" gives
ACCURACY OF FIELD DATA AND COMPUTED RESULTS 7

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"). Values 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 values 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 and footnote unless they 

were 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.

341092 O - 55 - 2
SURFACE WATER SUPPLY, 1953, 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 tables 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 beer) 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 Western Colorado Power Co. continued, during the water year October 1952 to September 1953, to collect records of daily discharge for Cascade Creek near Tacoma, Colo., 

which now cover the years 1915-53. The records for the years 1934-40 are published in the 

surface water-supply papers of the Geological Survey covering the Colorado River basin for 

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

Engineer of Colorado and the Denver district office of 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 during most of the year over all 

of the lower Colorado River basin. In the upper basin, streamflow during most of the 

year ranged from near normal in the northern part to deficient runoff in the southern 

part. No noteworthy floods occurred in the area covered by this report during the year. 

For three key gaging stations in the area covered by this report, a comparison of monthly 

and annual mean discharges during the 1953 water year with the median discharges for the 

25-year period 1921-45 is shown in figure 3 on the following page.

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

September 1899, October 1901 to October 1906 (published as "at Whitewater) , October 

1916 to September 1953 (October 1928 to December 1933 monthly discharge only, published 

in WSP 1313).

Gage. Water-stage recorders on river and canal. Datum of river gage is 4,566.14 ft above 

mean sea level, datum of 1929. Datum of canal gage is 4,567.14 ft above mean sea level, 

datum of 1929. Prior to Apr. 1, 1917, staff or chain gages at sites if miles downstream near mouth and 12 miles upstream at Whitewater at various datums. Apr. 1, 1917, 

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

Average discharge (combined flow). 45 years (1896-99, 1901-6, 1916-53), 2,730 cfs.

Extremes (combined flow) . Maximum discharge during year, 14,100 cfs June 14; minimum daily, 

624 Cfs Aug. 20-22.

1896-99, 1901-6, 1916-63: 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. Combined 

flow of river and Redlands -power canal minus about 40 cfs diverted during irrigation 

season represents entire flow that enters Colorado. River from Gunnison River basin. 

Records include flow of power canal. Natural flow of river affected by diversions for 

irrigation of about 233,000 acres above station, small diversions out of basin, small 

storage reservoir, and return flow from irrigated lands. Records of chemical analyses 

and water temperatures for the water year 1953 are given in WSP 1293.

GREEN RIVER BASIN 241

Uinta River near Neola, Utah

Location. Lat 40°32'10", long. 110°04'00", in SW£ (revised) sec. 25, T. 2 N., R. 2 W., 

Uinta meridian, on left bank 300 ft downstream from bridge, three-quarters of a mile 

upstream from Pole Creek, and 7 miles north of Neola.

Drainage area. 181 sq mi.

Records available.--July 1921 to September 1927 (fragmentary), September 1929 to September 1953.

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

Eb 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. 25 years (1925-26, 1929-53), 175 cfs.

Extremes. Maximum discharge during year, 2,200 cfs June 13 (gage height, 4.78 ft); minimum, 31 cfs Apr. 13.

1929-53: 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 stage, 5.57 ft 

June 18, 1949, site and datum then in use; minimum discharge recorded, that of Apr. 13, 

1953.

Remarks. Records good except those for periods of ice effect, which are fair. Water diverted from Pole Creek and Uinta River and used at Uinta Power & Light Co. powerplant, 

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 several small mountain lakes and reservoirs.

20 miles upstream from mouth.

Drainage area. 1,500 sq mi, approximately.

Records available. September 1909 to December 1910, January to August 1911 (gage heights 

only), November 1945 to September 1953.

Gage. Water-stage recorder. Altitude of gage is 4,600 ft (by barometer). September 1909 

To August 1911, reference point at site 100 ft upstream at different datum.

Average discharge. 7 years (1946-53), 119 cfs.

Extremes. Maximum discharge during year, 4,650 cfs Aug. 88 (gage height, 5.11 ft); minimum not determined, probably occurred during period of ice effect or no gage-height 

record.

1909-11, 1945-53: Maximum discharge observed, 8,100 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, September 1910.

Remarks. Records good except those for periods of ice effect 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. Flow 

affected by storage in Scofield Reservoir since 1926 (see p. 262). Records of chemical analyses and water temperatures for the water year 1953 are given in WSP 1293.

Saleratus Wash at Green River, Utah

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

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

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

Records available . October 1948 to September 1953.

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

Average discharge. 5 years, 2.97 cfs.

Extremes. Maximum discharge during year, 1,340 cfs Aug. 1 (gage height, 5.78 ft); no flow 

at times.

1948-53: 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.

River, 0.9 mile upstream from Colorado-New Mexico State line, and 1 mile north of Rosa.

Drainage area. 1,990 sq mi, approximately.

Records available. July 1895 to September 1899, September 1910 to September 1953 (December 1896, December 19-10, January and February 1912, January 1915 to September 1930 

monthly records only, published in WSP 1313). Prior to October 1920, published as two 

stations, Piedra and San Juan Rivers at Arboles, Colo., sum of which is equivalent.

Gage. Water-stage recorder. Altitude of gage is 5,980 ft (from river-profile map). Priorto Oct. 1, 1920, at sites on Piedra and San Juan Rivers at Arboles, Colo. (see WSP 1313 

for descriptions). Oct. 1, 1920, to Apr. 12, 1922, chain gage 75 ft downstream at different datum. Apr. 13, 1922, to Sept. 18, 1930, water-stage recorder 550 ft upstream 

at datum 0.7 ft higher. Sept. 19, 1930, to Aug. 31, 1938, water-stage recorder at sites 

330 and 430 ft upstream at datum 1.0 ft higher. Sept. 1, 1938, to Dec. 19, 1949, waterstage recorder at present site at datum 1.0 ft higher.

Average discharge. 44 years (1896-97, 1910-53), 1,272 cfs.

Extremes. Maximum discharge during year, 5,400 cfs May 29 (gage height, 6.22 ft); minimum 

daily, 45 cfs Sept. 27, 28.

1920-53: Maximum discharge, about 25,000 cfs June 29, 1927 (gage height, 13.5 ft, 

from estimated graph, site and datum then in use), from rating curve extended above 

8,000 cfs by logarithmic plotting; minimum daily, that of Sept. 27, 28, 1953.

Maximum flood known occurred Oct. 5, 1911. A major flood occurred Sept. 5 or 6, 1909.

Remarks. Records good except those for periods of ice effect, which are poor. Discharge 

measurements generally made 4 to 6 times a month. Diversions for irrigation of about 

14,000 acres above station.

Revisions (water years). WSP 1313: 1896-97, 1910-11, 1914.

Records available. June 1907 to October 1910 (gage heights only, January to October 1910) 

and October 1927 to September 1953 (October 1927 to September 1930 monthly discharge 

only, published in WSP 1313) in reports of Geological Survey. Published as "at Turley" 

1907-8.

Gage.--Water-stage recorder. Altitude of gage is 5,540 ft (from river-profile map).

Prior to Nov. 30, 1908, staff gage at site 4 miles upstream at different datum. Dec. 9,

1908. to Sept. 27, 1909, chain gage and Sept. 28, 1909, to Oct. 31, 1910, staff gage, 

at site half a mile downstream at different daturas. Oct. I, 1927, to Dec. 20, 1950, 

water-stage recorder at present site at datum 1.0 ft higher.

Average discharge. 28 years (1907-9, 1927-53), 1,472 cfs.

Extrrme?. --Maximum discharge during year, 5,310 cfs May 29 (gage height, 6'.06 ft); minimum 

daily, 70 cfs Sept. 29.

1927-53: Maximum.discharge, 25,000 cfs Aug. 11, 1929 (gage height, 9.70 ft, present 

datum); minimum daily, 17 cfs Aug. 18, 24, 25, 1939.

Maximum stage known, 21 ft, present datum, Oct. 5 or 6, 1911. Flood of Sept. 6,

1909. reached a stage of about 11 ft, site and datum then in use (discharge probably 

exceeded that of 1929). Flood of June 29, 1927, was of about the same magnitude as 

those of 1909 and 1929.

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

record, which are poor. Discharge measurements generally made 3 or 4 times a month. 

Diversions for irrigation of about 48,000 acres above and 4,500 below station. Records 

of chemical analyses, water temperatures, and sediment loads for the water year 1953 

are given in WSP 1293.

8.5 ft, site and datum then in use), from rating curve extended above 10,000 cfs by 

logarithmic plotting; minimum daily, 5.4 cfs Sept. 1, 1950.

Maximum flood known occurred Oct. 6, 1911, when a stage of about 16.5 ft, present 

site and datum, was reached. Flood of Sept. 6, 1909, reached a stage of 11.1 ft, 1904-5 

site and datum (discharge, about 19,000 cfs).

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

which are poor. Discharge measurements generally made 2 to 4 times a month. Diversions 

for irrigation of about 30,000 acres above station. Records of chemical analyses, water 

temperatures, and sediment loads for the water year 1953 are given in WSP 1293.

San Juan River near Bluff, Utah

Location. Lat 37°09', long. 109°52', in SW^ 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 1953 (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 

daturas.

Average discharge. 39 years (1914-53), 2,918 cfs.

Extremes. Maximum discharge during year, 9,270 cfs July 30 (gage height, 10.20 ft); minimum, 112 cfs Sept. 13.

1914-17, 1927-53: 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. 24-37, 

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 

sediment loads for the water year 1953 are given in WSP 1293.

Revisions (water years). WSP 1213: 1940. WSP 1313: 1917, 1929.

Extremes. Maximum discharge during year, 69,600 cfs June 17 (gage height, 15.60 ft); minimum, 3,160 cfs Sept. 30 (gage height, 6.08 ft).

1921-53: Maximum discharge, 220,000 cfs June 18, 1921 (gage height, 26.5 ft, from 

floodmarks), from rating curve extended above 120,000 cfs on basis of discharge computed for station near Grand Canyon; minimum, 750 cfs Dec. 27, 1924 (gage height, 4.2 

ft).

Maximum discharge known, about 300,000 cfs July 7, 1884 (gage height, 31.5 ft, present site and datum, from floodmark at mouth of'Paria River), from rating curve extended 

above 120,000 cfs on basis of discharge computed for flood of June 18, 1921, for station near Grand Canyon.

Remarks. Records excellent. Natural flow of stream affected by transmountain diversions, 

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

irrigation, and return flow from irrigated areas. Discharge measurements generally 

made once a week during normal flow and more often during high water. Records of 

chemical analyses, water temperatures, and sediment loads for the water year 1953 are 

given in WSP 1313.

Revisions (water years) .--WSP 859: 1921-23. WSP 1313: 1914-21.

LITTLE COLORADO RIVER BASIN 335

Little Colorado River below Lyman Reservoir, near St. Johns, Ariz.

Location. Lat 34°22', long. 109°23', in SW^NE^ see. 9, T. 11 N., R. 28 E., 65 ft downstream from outlet tunnel in Lyman Dam and 9 1/3 miles south of St. Johns. 

Drainage area. 790 sq mi, approximately. 

Records available .--April 1941 to September 1953.

Gage. Water-stage recorder and concrete control for determination of quantity of water 

released to river channel. Altitude of gage is 5,920 ft (from river-profile map). 

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

three-eights of a mile north in SWi sec. 4, T. 11 N., R. 28 E. 

Average discharge. 12 years, 2.73 cfs.

Extremes.--Maximum daily discharge during year, 9.0 cfs Aug. 4-6; minimum dally, 0.1 cfs 

(leakage) for several months.

1941-53: Maximum discharge observed, 603 cfs May 8, 1941 (including 546 cfs of 

spilled water); no flow at times.

Remarks. Records fair. Record of daily discharge 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. Flow completely regulated by many 

reservoirs (combined capacity, 46,900 acre-ft, the largest of which is Lyman Reservoir (capacity, 31,390 acre-ft, adjusted in 1952 for accumulation of sediment). Diversions above station for irrigation of about 8,200 acres, including 1,500 acres 

served by Lyman Canal. Flow past this station supplemented by spring inflow downstream used to irrigate an additional 2,000 acres in vicinity of St. Johns.

1953.

Average discharge. 5 years (1905-6, 1949-53), 94.7 cfs.

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

1929. March 1905 to December 1909 staff gage at former highway bridge just upstream 

from present bridge at different datum.

Extremes.--Maximum discharge during year, 6,030 cfs July 29 (gage height, 7.53 ft); no flow 

at times April to June.

1905-9, 1949-53: Maximum daily discharge, 20,200 cfs Nov. 27, 1905; no flow at times 

in 1951 and 1953.

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 poor. Diversions above station for irrigation of about 23,000 acres. 

Some regulation by reservoirs (combined capacity, about 73,000 acre-ft).

Revisions (water years). WS? 1313: 1906.

datum), from rating curve extended above 13,500 cfs on basis of velocity-area studies 

and verified by slope-area determination at gage height 13.4 ft; no flow for many days 

in each year.

Ploodmarks 3 ft higher than stage of flood of Apr. 4, 1929, were found in 1929, 

1,850 ft downstream from gage.

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

Water diverted above station for railroad and minor municipal uses. Winslow principal 

water supply is from recently drilled wells. Records show discharge over dam and do 

not include flow in canal that diverts at dam or leakage through dam. Plow in the canal 

was measured May 14, 5.27 cfs. Leakage was measured Oct. 28, 2.1 cfs; May 14, 2.74 cfs;

ft above mean sea level.

Drainage area. 5.090 sq mi, approximately. 

Records available. October 1929 to September 1953.

Gage. Water-stage recorder. Datum of gage is 1,763.68 ft above mean sea level, datum of 

1929. Prior to May 27, 1933, staff gage at site 300 ft upstream and May 28, 1933, to 

Nov. 7, 1939, at present site, both at datum 2.53 ft higher. Nov. 8, 1939, to Mar. 31, 

1942, staff gage at present site at datum 2.00 ft higher.

Average discharge. 24 years, 251 cfs.

Extremes. Maximum discharge during year, 5,490 cfs Aug. 27 (gage height, 8.66 ft); minimum, 62 cfs for several days in June and September.

1929-53: Maximum discharge, 22,000 cfs Mar. 3, 1938 (gage height, 12.8 ft, present 

datum, from floodmarks), by slope-area determination of peak flow; minimum observed, 50 

cfs for many days in several years, resulting from nearby fairly uniform spring inflow.

Remarks. Records good. Diversions above station for irrigation of about 18,000 acres, 

of which 600 are below station. See supplemental discharge measurements for occasional 

determinations of spring inflow in this vicinity. Records of chemical analyses, water 

temperatures, and sediment loads for water year 1953 are given in WSP 1293.

Revisions (water years). WSP 959: 1932. WSP 979: 1930-31, 1933-37. WSP 1313: 1940(M).

gage is 1,432.16 ft above mean sea level, datum of 1929 (Bureau of Reclamation benchmark). May 1913 to September 1916, staff gages at sites 14^ and 15 miles downstream 

at different datums (sites now submerged by Lake Mead).

Extremes.--Maximum discharge during year, 37 cfs Jan. 19 (gage height, 0.62 ft); no flow 

for many days.

1913-16, 1947-53: 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.

Remarks. Records good prior to Mar. 1, poor thereafter. Daily records not sufficiently

 accurate for publication. 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 19 discharge 

measurements and field estimate^. Many diversions above station for irrigation. Water 

diverted at dam for irrigation clownstrean or for storage in Bowman Reservoir is not 

included in this record. Considerable waste and drainage return flow enters river 

below station. Supplemental discharge measurements, in cubic feet per second, of 

diversions were made as follows:

Colorado River aqueduct near Parker Dam, Ariz.-Calif.

375

Location. Lat 34e 19'00", long. 114e 09'25", in NWiSWfc sec. 28, T. 3 N., R. 27 E., San 

Bernardino meridian, at Intake pumping plajnt or Metropolitan Water District of Southern California on Havasu Lake, 1.8 miles upstream from Parker Dam, and 156 miles downstream -from Hoover Dam.

Records available. January 1939 to September 1953 (monthly records only after October 

1942.see summary in WSP 1313).

Page. Venturi meters in pressure lines at Intake pumping plant.

Average discharge. 14 years, 164 cfs.

Extremes. 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. During this year 1,110 acreft 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 the 

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

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

to September 1953 (monthly discharge).

Remarks. Figures given herein show water diverted to project and surface return flow

through drainage canal at lower end of project. Daily diversions estimated on basis of 

current meter measurements made once a week and adjusted between measurements on basis 

of gate changes at canal intake. Surface return flow to Colorado River through drainage canal estimated on basis of current meter measurements made once a week. Only 

monthly records are published. Water used for irrigation of 33,777 acres this year 

on east side of Colorado River between Parker and Ehrenberg.

DIVERSIONS BETWEEN PARKER DAM AND IMPERIAL DAM 

Palo Verde Canal near Blythe, Calif.

Location. Lat 33°44 I 00", long. 114°30'45", in NEftjw£ sec. 19, T. 5 S., R. 24 E., San 

Bernardino meridian, at canal intake structure 10 miles northeast of Blythe and 43 

miles downstream from Headgate Rock Dam. Prior to Dec. 1, 1952, at site 300 ft 

downstream.

Records available.--January 1922 to December 1923, January 1925 to September 1953 (prior 

to October 1950, monthly discharge only).

Gage. Recording gage to obtain total gate opening and water-stage recorders above and 

Delow intake gates to record head. Datum of gages is 280.99 ft above mean sea level, 

datum of 1929. Aug. 7, 1950, to Nov. 30, 1952, water-stage recorder on tailrace and 

auxiliary recorder half a mile downstream, at same datum. For description of gages 

and determination of discharge prior to Aug. 7, 1950, see WSP 1313.

Remarks.--Records good except those for period Oct. 29 to Feb. 23 when large part of flow 

was returned to river downstream from gates, which are poor. Figures given herein 

represent flow diverted from Colorado River for irrigation of 66,532 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.

Return flow through Outfall drain, as measured in NE£ sec. 11, T. 9 S., R. 21 E., 

1 mile south of Palo Verde is given in table below.

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. July 13, 1934, to Sept. 30, 1942, water-stage 

recorder at site 14* miles upstream at datum 167.38 ft above mean sea level, datum of 

1929.

Willow Creek near Point of Pines, near Morenci, Ariz.

Location. Lat 33°22'45", long. 109a 39'00", in NWi sec. 2, T. 1 S., R. 26 E., unsurveyed, 

in San. Carlos Indian Reservation on right bank at head of box canyon, 4 miles east of 

Point of Pines, 10 miles west of Double Circle Ranch, and 23 miles northwest of Morenci.

Drainage area. 102 sq mi.

Records available. August 1944 to September 1953.

Gage. Water-stage recorder and concrete control. Altitude of gage is 5,804 ft (by 

barometer).

Average discharge. 9 years, 11.8 cfs.

Extremes.--Maximum discharge during year, 378 cfs July 8 (gage height, 5.04 ft), from 

rating curve extended above 60 cfs on basis of slope-area determination at gage height 

10.1 ft; no flow for many days from December to February.

1944-53: Maximum discharge, 2,590 cfs Jan. 13, 1952 (gage height, 10.1 ft), from 

rating curve extended above 60 cfs on basis of slope-area determination of peak flow; 

no flow for many days each year.

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

fair. Almost all flow of less than 20 cfs past this station is water pumped from Black 

River (see record on preceding page).

Revisions (water years). WSP 1213: 1945-47, 1948(P), 1949.

392 GILA RIVER BASIN

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, 3£ miles downstream from Double Circle Ranch, and 17 miles northwest of 

Morenci.

Drainage area.--377 sq mi.

Records available. August 1944 to September 1953.

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. 9 years, 21.5 cfs.

Extremes. Maximum discharge during year, 456 cfs Aug. 1 (gage height, 4.68 ft), from 

rating curve extended above 170 cfs on basis of slope-area determination at gage 

height 8.51 ft; minimum, 3.4 cfs Jan. 12.

1944-53: 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, 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. 389).

Inflow between station and point 2£ miles downstream, below Sheep Wash, as determined by discharge measurements, was measured as follows: 4.1 cfs Jan 3; 4.2 cfs 

Apr. 3; 4.6 cfs on June 30; and 4.6 cfs on Sept. 8. Discharge measurements or estimates, in cubic feet per second, of the combined flow of Eagle Creek 900 ft above 

Willow Creek and Double Circle ditch are given below.

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.

 Records excellent except those above 90 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, 51? miles upstream from this station, for about 

three-quarters of the year (see p. 389). Diversions by pumping for mining, metallurgical treatment of ore, and domestic use in and near Morenci and Clifton are made from 

Eagle Creek, 2f 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.

Twelve canals, listed in 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 

Colvln-Jones Canal, at lower end, is 25.8 miles upstream from station at Calva. Record 

of canals obtained below wasteways used for regulation.

Records available.--1936-53 (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 Colvln-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.

Pages. 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.

on left bank 2,200 ft downstream from Coolidge Dam.

Drainage area. 12,886 sq mi (revised).

Rec ords avallab1e. July 1899 to November 1905 (fragmentary), August 1910 to February 1911 

Igage nelgnts and discharge measurements only), April 1914 to September 1953.

Gage. Water-stage recorder and 30 ft concrete Parshall flume. Datum of gage is 2,309.33 

rt 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 datums.

Average discharge. 41 years (1901, 1904, 1914-53), 388 'Cfs (adjusted for storage in San 

Carlos Reservoir).

Extremes. Maximum discharge during year, 373 cfs Dec. 16 (head on flume, 2.13 ft); minimum daily, 0.6 cfs Sept. 30.

1914-53: 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); no flow at Coolidge Dam at times in most years when gates in dam 

were closed.

Remarks. Records excellent except those below 5 cfs, which are fair. Discharge measurements 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 page). Record includes flow of Warm Springs which enters between dam and 

gage and was measured as 0.78 cfs on Oct. 11, 0.52 cfs on May 11, and 0.46 cfs on 

Sept. 11.

GILA RIVER BASIN 403

San Pedro River at Charleston, Ariz.

Location. Lat 31°37'40",- long. 110°10'30", in NE^NEi sec. 11, T. 21 S., R. 21 E., in 

Spanish land grant of San Juan de las Boquillas y Nogales, at downstream side of pier 

near center of highway bridge a quarter of a mile south of Charleston, ij miles upstream from Charleston dam site, 8| miles upstream from Babocomari River, and 29 miles 

upstream from Benson.

Drainage area. 1.219 sq mi, of which 696 sq mi is in Mexico.

Recorgs available. January 1904 to August 1906 (January and February 1904, gage heights 

only), October 1910 to August 1912 (discharge measurements and some gage heights), 

September 1912 to September 1953. Published as "near Lewis Springs" 1910-11, "near 

Pairbank" 1911-26, and "at Fairbank" 1912.

Gage. Water-stage recorder and concrete control. Datum of gage is 3,954.26 ft above mean 

sea level, datum of 1929. Prior to Dec. 1, 1942, staff gage or water-stage recorder at 

various sites within 65 miles downstream at different datums.

Average discharge. 42 years (1904-5, 1912-53), 65.5 cfs.

Extremes. Maximum discharge during year, 8,590 cfs July 7 (gage height, 8.2 ft); minimum 

1.5 cfs June 26.

1916-53: Maximum discharge, about 98,000 cfs Sept. 28, 1926 (gage height, 21.9 ft, 

site and datum then in use), by slope-area determination of peak flow; minimum since 

1928, 0.9 cfs June 26, 27, 1951.

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

Diversions, mostly by pumping from ground water, for irrigation of about 1,600 acres 

above station, Including an estimated 200 acres in Mexico. Record shows flow at 

Charleston dam site.

Revisions (water years). WSP 1119: 1939(m). WSP 1213: 1914, 1916(M), 1918(M), 1919,

Gila River at Kelvin, Arlz.

405

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-J miles upstream from Ashurst-Hayden Dam.

Drainage area.--18,Oil sq mi, of which 5,125 sq mi is below Coolidge Dam (revised). 

Records available.--January 1911 to September 1953.

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 water-stage recorder 900 Ft upstream since May 27, 1951.

Average discharge. 42 years (1911-53), 519 cfs (adjusted for storage in San Carlos 

Reservoir).

Extremes. Maximum discharge during year, 4,210 cfs July 7 (gage height, 7.1 ft); minimum 

daily, 0.6 cfs July 3.

1911-53: Maximum discharge, about 132,000 cfs Jan. 20, 1916 (gage height, 19.5 

ft), from rating curve extended above slope-area determination at gage height 16.2 ft; 

minimum, less than 1 cfs in summers of several years.

Maximum discharge since completion of Coolidge Dam, 42,800 cfs Aug. 8, 1930 (gage 

height, 12.6 ft); minimum, less than 1 cfs in summers of several years.

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

which are poor. Discharge measurements generally made twice a month October to February and three times a month March to September. Large diversions above station for 

irrigation, of which more than 90 percent are above Coolidge Dam. About 61,000 acres

406 GILA RIVER BASIN

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

Location. Lat 33°06'00", long. 111°14'50", In SW$NW£ see. 8, T. 4 S., R. 11 E., on left 

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

Drainage area. 18.305 sq mi.

Records available. July 1923 to September 1953 (head on crest of dam only). Records of 

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

iy53 * Gage. Water-stage recorder. Permanent crest of dam Is 1,562.6 ft above mean sea level, 

datum of 1929. Crest height was 1.77 ft higher during year 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 diversions. Prior to Jan. 12, 1937, water-stage recorder 900 ft downstream from Ashurst-Hayden Dam.

Extremes. Maximum head on dam during year, 2.0 ft July 29; no flow over dam greater part 

of year.

1923-53: Maximum head on dam, 8.0 ft Sept. 28, 1926; no flow over dam greater part 

of each year.

Remarks. Records show daily mean head on dam and monthly diversions to Florenee-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-aere 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 is by pumping 

from ground water.

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

Location. lat 34°10'40", long. 110°01'00", In SWi sec. 16, T. 9 N., R. 22 E., on boundary 

of Fort Apache Indian Reservation, on right bank 170 ft below terminal structure of 

Show Low Creek diversion works, 4,350 ft west of pumping plant on Lake Show Low, and 

7 miles by road south of Show Low.

Records available. May to September 1953.

Gage. Water-stage recorder and V-notch sharp-crested weir. 

above mean sea level (Bureau of Reclamation benchmark).

Datum of gage is 6,621.57 ft

Extremes. Maximum daily discharge during period, 17.2 cfs May 21; no flow most of period.

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

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

First diversion began May 14, 1953, except that pump testing caused minor flow May 8.

Thirteen discharge measurements made during May.

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

Jaques Dam in NW£ 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

GILA RIVER BASIN 429

Salt River near Chrysotile, Ariz.

Location.--Lat 33°48', long. 110°30', in sec. 25, T. 6 N., R. 17 E., unsurveyed, in San 

Carlos Indian Reservation, on left bank 1,200 ft upstream from bridge on U. S. Highway 60, 5? miles northeast of Chrysotile, 8 miles, upstream from Cibecue Creek, and 

33 miles downstream from confluence of Black and White Rivers.

Drainage area.--2.850 sq mi, approximately.

Records available.--September 1924 to September 1953.

Gage. Water-stage recorder. Datum of gage is 3,354.57 ft above mean sea level, datum 

of 1929.

Average discharge.--29 years, 617 cfs.

Extremes.--Maximum discharge during year, 3,680 cfs July 30 (gage height, 5.01 ft); minimum, 73 cfs Sept. 28 (gage height, 1.29 ft).

1924-53: Maximum discharge, 52,900 cfs Feb. 7, 1937 (gage height, 15.18 ft); minimum, 58 cfs July 11, 1951 (gage height, 1.19 ft).

Flood peak of 74,000 cfs (gage height, 18 ft, from floodmarksj, from rating curve 

extended above 52,000 cfs by logarithmic plotting, occurred prior to 1924 and is 

believed to be peak of flood of Jan. 19, 1916.

Remarks. Records excellent except those for periods of fragmentary or no gage-height 

record, which are good. Several small diversions for irrigation above station of 

about 3,100 acres, 1 transmountain diversion into the basin (see p.425 for record of 

Forestdale Creek diversion from Show Low Creek, near Show Low), and 1 transmountain 

diversion out of the basin (see p.389 for record of Willow Creek diversions from 

Black River, near Morenci).

1913-53: Maximum discharge, 117,000 cfs Mar. 14, 1941 (gage height, 24.4 ft), 

from rating curve extended above 55,000 cfs on basis of velocity-area studies and 

float-area measurements at 66,000 and 102,000 cfs; minimum, 60 cfs July 12, 1951. 

Minimum discharge known, about 42 cfs Aug. 5, 1911.

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

good. Several small diversions for irrigation of about 4,000 acres above station. 

Two transmountain diversions above station, one into basin from Show Low Creek and one

432 GILA RIVER BASIN

Reservoir system on Salt River at and below Roosevelt Dam, Ariz.

Location. This system comprises 4 storage reservoirs created by 4 separate dams on Salt 

River; Roosevelt Lake, formed by Roosevelt Dam, in sec. 20, T. 4 N., R. 12 E., unsurveyed; Apache Lake, formed by Horse Mesa Dam, 17 miles downstream from Roosevelt Dam; 

Canyon Lake, formed by Mormon Plat Dam, 27 miles downstream from Roosevelt Dam; Sahuaro 

Lake, formed by Stewart Mountain Dam, 37 miles downstream from Roosevelt Dam.

Drainage area. 6,210 sq mi (revised), approximately, at Stewart Mountain Dam.

Records available. July 1910 to September 1953 (prior to October 1934 contents at end of 

each month only, published in WSP 1049 and 1313.

Gage.--Roosevelt Lake: water-stage recorder operates above elevation 2,024 ft, staff

gage below; Apache Lake: water-stage indicator in powerplant connected to long distance 

transmitter on lake since April 1949; prior to that date staff gage or reference mark; 

Canyon and Sahuaro Lakes: mercury column gages.

Extremes. Maximum contents of system during year, 1,405,000 acre-ft Mar. 15-17; minimum 

contents, 1,007,000 acre-ft Sept. 30.

1910-53: Maximum contents, 1,764,000 acre-ft May 22, 1941; minimum contents, 20,680 

acre-ft Sept. 16, 1940.

Remarks. Records given herein represent usable contents. Dead storage negligible. Total 

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 aere-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 Roos&velt 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.

1,396.33 ft above mean sea level, datura of 1929.

Average discharge.--23 years, 860 cfs.

Extremes.--Maximum discharge during year, 2,200 cfs July 13 (gage height, 5.10 ft); no 

flow for many days.

1930-53: Maximum discharge, 11,700 cfs May 7, 1941 (gage height, 15.97 ft, site 

and datum then in use); no flow for many days November 1952 to February 1953.

Remarks. Records excellent except those between 5 and 50 cfs, which are good, and those 

below 5 cfs, which are poor. Discharge measurements generally made four times a month. 

Flow regulated at Stewart Mountain Dam and three other dams (combined capacity, 

1,755,000 acre-ft, see preceding page). Entire flow is diverted at Granite Reef Dam, 

10 miles dovmstream for irrigation in Salt River Valley. Records of chemical analyses 

and water temperatures for the water year 1953 are given in WSP 1293.

436 GILA RIVER BASIN

Verde River below Tangle Creek, above Horseshoe Dam, Arlz.

Location.--Lat 34°04'25", long. 111°42'5Q", In sec. 35, T. 9 N., R. 6 E., unsurveyed, in 

 Tonto National Forest, on left bank l£ miles downstream from Tangle Creek and 9 miles 

upstream from Horseshoe Dam.

Drainage area.--5.872 sq mi, revised (including 373 sq mi, revised, in Aubrey Valley Playa, 

a closed basin).

Records available. August 1945 to September 1953.

Gage. Water-stage recorder. Datum of gage is 2,029.0 ft above mean sea level, datum of ~~T929.

Average discharge.--8 years (1945-53), 416 cfs.

Extremes.--Maximum discharge during year, 6,390 cfs Aug. 29 (gage height, 10.00 ft); minimum, 62 cfs June 27 (gage height, 1.42 ft), caused by power regulation on Fossil Creek. 

1945-53: Maximum discharge, 81,600 cfs 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 except those for period of no gage-height record, which are 

good. 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.

Extremes.--Maximum discharge during year, 1,230 cfs June 24 (gage height, 4.57 ft); min-

 Imum daily, 20 cfs Mar. 22.

1888-1939: Maximum discharge not determined (probably over 150,000 cfs, Feb. 24, 

1891); minimum daily, 29 cfs July 11, 13, 1901. Floods of Nov. 27, 1905, and Mar. 4, 

1938, reached maximum discharges of 96,000 and 95,000 efs respectively.

1939-53: Maximum discharge, 45,800 efs Mar. 15, 1941 (gage height, 17.5 ft, present site and datum, from floodmarks); no flow at Bartlett Dam at times in several 

years when gates in dam were closed.

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

acres, some of which is by pumping from ground water. Flow completely regulated by Bartlett Dam since Feb. 5, 1939, and by Horseshoe Dam since Nov. 15, 1945 (see preceding 

page), except during periods of spill. Discharge measurements generally made four 

times a month. Records of chemical analyses and water temperatures for the water year 

1953 are given in WSP 1293.

downstream from canal intake, 0.7 mile downstream from Agua Fria River, 3 miles southwest of Avondale, and 4 miles downstream from Salt River.

Records available. Hay to September 1953.

Gage. Water-stage recorders and 15-foot concrete Parshall flume. Datum of gage is 

t?04.62 ft above mean sea level, datum of 1929, supplementary adjustment of 1949.

Extremes.--Maximum daily discharge during period, 170 cfs July 31; no flow for several 

days.

Remarks. Records excellent except those for periods of doubtful or no gage-height recorTT which are fair. Canal diverts from right bank of Gila River in SE^SW^ sec. 28, 

T. 1 N., R. 1 W., for irrigation in the Buckeye area. Total irrigated acreage in the 

Buckeye Irrigation District is 17,480 acres. Record includes waste water and flow 

from canals of Salt River project, delivered through Buckeye feeder ditch to the Gila 

River channel in SW^Nw£ sec. 34, T. IN., R. 1 W., near mouth of Agua Fria River. 

Difference in flow of canal and Feeder ditch gives diversion from Gila River except 

for channel losses and minor waste water entering canal from nearby fields of Salt 

River project.

Cooperation. Most of record May 1-25 furnished by Salt River Valley Water Users' Assoelation and Buckeye Irrigation Co. Record of Buckeye feeder ditch furnished by Salt 

River Valley Water Users' Association.

GILA RIVER BASIN 441

Agua Fria River at Lake Pleasant Dam, Ariz.

Location.--Lat 33°51', long. 112 016', In NW£ sec. 21, T. 6 H., R. IE., at left upstream

 end of Lake Pleasant Dam, 22 miles northwest of Glendale and 24f miles upstream from

mouth of New River.

Drainage area. 1.460 sq mi, approximately. 

Records available. November 1910 to September 1914 (gage heights and discharge measure-

 ' merit's only); October 191'4 to September 1919, October 1919 to September 1924 (gage

heights only and some discharge measurements), October 1933 to September 1953 (monthly

discharge).

Gage --Staff gage on Lake Pleasant sead twice daily. Datum of gage is 1,431.2 ft above 

"inean sea level, datum of 1929. Prior to Sept. 30, 1924, staff gage or water-stage

recorder, at different datum, at several sites in the 'vicinity of diversion dam 1£

miles downstream from Lake Pleasant Dam. 

Average discharge. 25 years (1914-19, 1933-53), 106 cfs. 

Extremes.--1910-24. 1933-53: Maximum discharge, about 105,000 efs Jan. 28, 1946 (gage

 height, 30 ft, same datum as in 1919, from floodmarks), Nov. 27, 1919 (gage height, 

33 ft, datum then in use, from floodmarks), from rating curve extended above 13,000 cfs 

on basis of velocity-area studies (on basis of comparative gage heights, the.flood of 

Nov. 27, 1919, is believed to have been the greater); no flow during spring and summer 

of several years.

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

 cEarge computed on basis of three factors as follows: 1. Change in contents of Lake 

Pleasant and in contents of small reservoir behind diversion dam l£ miles downstream 

from Lake Pleasant. 2. (a) Release from Lake Pleasant (see table below) as measured 

by water-stage recorder and sharp-crested rectangular weir in canal 650 ft downstream 

from intake at diversion dam, rated by current-meter measurements and frequently checked 

by a Clausen-Pierce weir rule; and (b) spill from Lake Pleasant as measured over diversion dam (none since May 13, 1941J. 3. Effect of rainfall and evaporation on lake; 

evaporation assumed as 0.85 of that measured once daily in 3-foot square land pan buried 

li ft in ground near left end of Lake Pleasant Dam. Effect of bank storage and bank 

release in Lake Pleasant is not taken into account. For months when inflow to lake is 

small and other factors relatively large, discordant figures of runoff may appear. Such 

discrepancies that may be attributed to inaccuracies in the capacity table or to the 

fact that bank storage and bank release are not taken into account, result in quantities too large for periods of falling stage but are compensated for by quantities too 

small for periods of rising stage. Inaccuracies in figures of release and evaporation, 

which may be within reasonable limits within themselves, may result in disproportionally 

large inaccuracies in small figures of inflow computed as residuals. Natural runoff 

from this basin during June was small. Diversions for irrigation above Lake Pleasant 

of probably not over 1,000 acres. Records of chemical analyses and water temperatures 

for the water year 1953 are given in WSP 1293.

Cooperation. Records collected and prepared in cooperation with Maricopa County Municipal water Conservation District No. 1.

Lake Pleasant at Lake Pleasant Dam, Arlz.

Location. Lat 33°51', long. 112°16', in NW£ sec. 21, T. 6 N., R. IE., at left upstream 

end of Lake Pleasant Dam on Agua Fria River.

Drainage area. 1.460 sq mi, approximately.

Records available. February 1928 to September 1953 (yearly data only, prior to 1939).

Gage. Staff gage read twice daily. Datum of gage is 1,431.2 ft above mean sea level, 

datum of 1929.

Extremes.--Maximum contents during year, 83,920 acre-ft Oct. 1 (gage height, 142.59 ft); 

minimum, 33,700 acre-ft Sept. 30.

1928-53: Maximum contents, 178,500 acre-ft Apr. 19, 1941 (gage height, 170.13 ft) 

of which 500 acre-ft 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, 163,800'acre-ft between gage heights 59 ft (25 ft above center line of outlet works) and 170.0 ft (top of spillway gates). There is no storage below gage 

height 59 ft because of accumulated sediment. Water released from reservoir flows 

down river channel l£ miles to diversion dam where it is diverted for irrigation near 

Beardsley. Figures given herein represent usable contents in Lake Pleasant. Contents 

of small reservoir formed by diversion dam is not included.

Cooperation. Page-height record furnished by Maricopa County Municipal Water Conservation District No. 1.

GILA RIVER BASIN

Qa,

Gila River below Gillespie Dam, Arlz.

Location. Lat 33°13'45", long. 112°46'00", In SE^NE^ sec. 28, T. 2 S., R. 5 W., at left 

end of Gillespie Dam, 8 miles downstream from Hassayampa River. Olla Bend Canal 

diverts from left bank and Enterprise Canal diverts from right bank at Olllesple Dam.

Drainage area. 49,620 sq ml (revised).

Records available. August 1921 to September 1953 (river below dam only). Records for 

Gila Bend Canal May 1935 to September 1953 (since October 1941, monthly discharges only); 

for Enterprise Canal June 1935 to September 1939 (discharge measurements and monthly 

estimates only), October 1939 to September 1953 (since October 1941, monthly discharges 

only). Combined discharge of river and Gila Bend and Enterprise Canals, June 1935 to 

September 1953, 1935-50 monthly discharge, published in WSP 1313 as Gila River above 

diversions at Gillespie Dam.

;e. --Gila River: Water-stage recorder since July 28, 1924. Datum of gage is 5.00 ft 

Below average elevation of crest of dam, which is 753.46 ft above mean sea level, datum 

of 1929. Prior to July 23, 1932, datum of gage was at average elevation of. dam crest. 

Aug. 4, 1921, to Nov. 10, 1924, depth of water read on crest at left end of dam. 

Gila Bend Canal: Water-stage recorder 200 ft downstream from headgates. 

Enterprise Canal: Water-stage recorder since Nov. 29, 1939, 600 ft downstream from 

intake.

Extremes. Maximum discharge over dam during year, 115 cfs Nov. 20 (gage height, 5.10 ft). 

An estimated peak discharge of about 1,000 cfs occurred below dam for a few minutes 

Aug. 2 during sluice period, most of which was from storage behind dam, estimated peak 

inflow did not exceed 150 cfs. No flow most of year.

1921-53: Maximum discharge observed, 85,000 cfs Dec. 28, 1923 (gage height, 11.0 ft, 

present datum); no flow for long periods each year.

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

Remarks. River records good except those for period of sluice Aug 2, which are fair. 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 acreft); 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 of chemical 

analyses and water temperatures for the water jear 1953 are given in WSP 1293.

Revisions (water years). WSP 1213: 1939. WSP 1243: 1924(M).

above siphon-drop powerplant (October 1947 to September 1953,monthly discharge only). 

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

wasteway (October 1946 to September 1953,monthly discharge only).

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

level of forebay of powerplant is 151.0 ft above mean sea level, datum of 1929, or 150.3 

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

gages on tailrace and in stilling well connected to forebay. Oct. 39, 1938, to Mar. 1, 

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

and Mar. 2, 1945, to Jan. 11, 1951, water-stage recorders on tailrace and forebay stilling 

well.

Average discharge. 27 years, 1,715 cfs.

Extremes.--Maximum daily discharge during year, 2,020 cfs Oct. 26, Nov. 14, 15, 16; minimum 

daily, 145 cfs Jan. 5.

1930-53: Maximum daily discharge, 2,040 cfs Nov. 11, 1943; no flow for some days in 

1937-39, 1945.

Remarks. Records excellent except those below 1,500 cfs, which are fair. Daily 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 mea'surements a month. Plow regulated by gates from All-Ameriean Canal. Records show quantity of water diverted from Ail-American Canal to Yuma Main Canal, except that diverted 

from forebay of powerplant to Walapai Canal. The water not needed for irrigation on 

Yuma project is returned to Colorado River through Yuma Main Canal wasteway, 3t miles 

downstream.

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

Walapai 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.

Cooperation. Record of turbine gate openings and diversions furnished by Bureau of Reclamation.

452 DIVERSIONS AND RETURN FLOWS AT AND BELOW IMPERIAL DAM

Yuma Main Canal wasteway at Yuma, Ariz.

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

raT"32°44'00", long. 114°37'20", in SW&SE£ sec. 26, T. 16 S., R. 22 E., San Bernardino meridian, 1,645 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 wasteway discharges into Colorado River in SW£ sec. 26, T. 

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

Records available. April 1913 to September 1953 (prior to October 1930 monthly discharge 

only, published in WSP 1313).

Average discharge. 25 years (1928-53), 1,258 cfs.

Extremes. Maximum daily discharge during year, 1,900 cfs Dec. 25; minimum daily, 142 cfs

1930-53: Maximum daily discharge, 2,020 cfs Dec. 24, 25, 1948; no flow for several 

days in 1937-39, 1945, 1950.

Remarks. Records good except those for Jan. 5, 8, and Feb. 12, which are poor. 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. Records of small irrigation diversions between Yuma Main Canal at siphon-drop 

powerplant and Yuma Main Canal below Colorado River siphon furnished by Bureau of 

Reclamation.

Discharge, in cubic feet per second, water year October 1952 to September 1953

DIVERSIONS AND RETURN FLOWS AT AND BELOW IMPERIAL DAM 453

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

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 SWtSEs sec. 26, T. 16 S., R. 22 E., San Bernardlno meridian, on left bank In California, 1,645 ft downstream from center of Yuma 

Main Canal wasteway gates and 3j miles downstream from siphon-drop powerplant. At outlet, In NW^NEu sec. 35, T. 16 S., R. 22 E., San Bernardlno 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 1953 (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 1953,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. Elevatipn 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. 29 years, 480 cfs.

Extremes. Maximum daily discharge during year, 84'3 cfs July 27; minimum daily, 3 cfs Jan. 5. 

1930-53: 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 50,000 acres in the Valley division of 

the Yuma project, and 2,290 acres in the unit B auxiliary project (until July 14 when 

unit was transferred to Gila project), and for supplementary municipal supply for city 

of Yuma. Records of chemical analyses for the water year 1953 are given in WSP 1293.

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 1952 to September 1953
