SURFACE WATER SUPPLY OP THE COLORADO RIVER BASIN, 1957

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, 1957. 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 13,750 gaging stations In the 48 States and at many 

others In the Territories of Alaska and Hawaii. On September 30, 1957, the Geological 

Survey and cooperating organizations were maintaining 7,030 gaging stations, Including 

those in Alaska and Hawaii. Discharge measurements only were made at many other points 

in the 1957 water year. The name of each stream measured at points other than gaging 

stations Is not listed in the index to this report. Only the major river basins In 

which measurements were made are listed under the Item "Discharge measurements" in the 

Index.

gaging-station records may usually be obtained from the district office.

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 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
EXPLANATION OP DATA 3

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 

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.

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-statlon 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

EXPLANATION OF DATA 5

tables gives the dally mean discharge, from which the monthly and the yearly mean discharge are computed. If the stage-discharge relation Is subject to change because of 

frequent or continual change in the physical features that form the control, the dally 

mean discharge is determined by the shifting-control method, in which correction factors 

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

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

a station is temporarily changed by the presence of aquatic growth or debris on the control, the dally 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.

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. Records are published for the water year which begins on 

October 1 and ends on September 30. A calendar for the water year 1957 Is shown on page 

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

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

504434 O - 59 - 2
6 SURFACE WATER SUPPLY, 1957, PART 9

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 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 nonreeording 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 nonreeording 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
EXPLANATION OF DATA 7

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.

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 noneontributing areas, OP 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 discharfts when the water was at crest stage. Likewise, the minimums in this summary are the minimum daily discharges.

Peak discharges and the time 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 published each year for all reservoirs for which records are published on a daily 

basis, but is not published for reservoirs for which only monthly data are given.

Discharge measurements and determinations of peak flows made at sites other than gaging 

stations are listed at the end of each report.

At many gaging stations water samples are collected from the streams for the purpose of 

making chemical analyses, computing dissolved solids, suspended sediment loads, and 

particle-size distribution, or measuring water temperatures. For most of these samples 

the results are published in an annual series of water-supply papers entitled "Quality of 

Surface Waters of the United States" which is issued in four volumes. In this report under 

"Remarks" a reference is made to quality-of-water records collected at gaging stations on 

a regular basis and published in the quallty-of-water reports. At many other gaging stations quality-of-water data are obtained at irregular intervals and published as "miscellaneous analyses" in the quality-of-water reports; such records are not referred to in 

"Remarks" paragraph in this report. At many gaging stations water temperature is obtained
8 SURFACK WATER SUPPLY, 1957, PART 9

also at the time a discharge measurement Is made; such temperature readings are not 

reported In the quality-of-water annual 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 *ther factors. For such stations, figures 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. 

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 

various parts are Indicated by the following list and the map In figure 2.

HYDROLOGIC CONDITIONS H

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 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.

The reports listed in the foregoing table 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 4 areas of 

less than 800 acres.

HYDROLOGIC CONDITIONS

The water year began with runoff below median throughout the area covered in this 

report and remained so generally for the first six months of the water year. Runoff was 

at a record low fier October in San Juan River ab Parmington, N. Mex., and remained so until 

January. Virgin River at Littlefield, Ariz., reached a record low for November and the 

Little Colorado River near Cameron, Ariz., was dry Sept. 1, 1956, to January 1957, the 

longest period of no flow in a record that extends back to 1921, and the first time there 

has been no flow the entire month of December. In January, the flow at this station was 

the third highest for January since 1922. Runoff for calendar year 1956 in Arizona shows 

significantly the effect of the drought as record low or near record low runoff occurred 

over most of the State. Reservoir storage was lowest in many years. Excessive runoff 

occurred in streams draining the intermediate elevations in Arizona during January and 

February. Flow of Rillito Creek near Tucson was the highest for January since 1920. High 

runoff in Colorado during the period June to September was caused by snowmelt from the 

unusually heavy snow pack during the previous winter. Momentary maximum and minimum 

dailies for the months of July and August on Roaring Pork at Glenwood Springs, Colo., were
12 SURFACE WATER SUPPLY, 1957, PART 9

exceeded this year as a result of this snowmelt. In Utah, runoff in the Colorado River 

near Cisco and San Juan River near Bluff was record high for July. The maximum daily flow 

of Colorado River near Cisco was the greatest of record, exceeding that of the high-water 

year 1917. The water year ended with runoff, well above median except in Arizona where it 

was Just above median in the southeast and well below median throughout the rest of the 

State. Runoff was excessive in the upper Colorado River basin during the last six months 

of the water year. For three key gaging stations in the area covered by this report, a 

comparison of monthly and annual mean discharges during the 1957 water year with the median 

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

Pall Creek near Pall Creek, Colo.

Location. Lat 37°58', long 108°01', In sec. 24, T. 43 N. , R. 11 W., on left bank 

2.7 miles upstream from mouth and 2.8 miles south of town of Pall Creek.

Drainage area. 33.5 sq ml.

Records available. August 1941 to September 1957. Monthly discharge only for some 

periods, published In WSP 1313.

Sage. Water-stage recorder. Datum of gage Is 7,928.79 ft above mean sea level (Bureau 

of Reclamation benchmark). Prior to Aug. 24, 1949, at datum 2.00 ft higher.

Average discharge. 16 years, 24.8 cfs (17,950 acre-ft per year).

Extremes. Maximum discharge during year, 1,390 cfs May 4 (gage height, 6.19 ft, from 

floodmarks), result of release of temporary storage caused by mud slide Just upstream, 

from rating curve extended above 240 cfs on basis of slope-area determination of peak 

flow; minimum daily, 2.2 cfs Mar. 7.

1941-57: Maximum discharge, that of May 4, 1957; minimum not determined, occurred 

during period of no gage-height record.

Remarks. Records poor. Slight regulation by Sylvan Lake Reservoir (capacity,

230 acre-ft). One diversion exports water above station to Beaver and Saltado Creek 

basins for irrigation of about 2,000 acres. Diversions for irrigation of 200 acres 

above station.

GREEN RIVER BASIN 

Ulnta River near Neola, Utah

257

Location. Lat 40°32'10", long 110°04'00", In SW£ sec. 25, T. 2 N. , R. 2 W. , Ulnta 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 (no winter records 1922-25, 1927) SeptemDer 1929 to September 1957.

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 waterstage recorder at present site at datum 1.14 ft higher.

Average discharge.--29 years (1925-26, 1929-57), 171 cfs (123,800 acre-ft per year).

Extremes.--Maximum discharge during year, 2,020 cfs June 8 (gage height, 4.90 ft); minimum 

not determined, probably occurred during period of no gage-height record.

1929-57; 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 24 cfs 

Mar. 31, Apr. 1, 1954.

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

Summer flow slightly regulated by storage in several small mountain lakes and reservoirs. 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. Discharge measurements, in cubic feet per second, during the water year 

1957, of Pole Creek canal are as follows:

May 28.......... 2.58

June 6.......... 1.21

June 13.......... 3.77

June 26.......... 1.00

July 10.......... 7.13

GREEN RIVER BASIN 381

Saleratus Wash at Green River, Utah

Location. Lat 38°59'20", long 110°09'40" (revised), in NE£ sec. 16, T. 21 S., R. 16 E., 

on left bank a quarter of a mile southeast of Green River and 1 mile upstream from 

mouth. Prior to July 28, 1955, at site 1,300 ft downstream.

Records available. October 1948 to September 1957.

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

Prior to July 28, 1955, at site 1,300 ft downstream at different datum.

Average discharge.--9 years (1948-57), 2.71 cfs (1,960 acre-ft per year).

Extremes. 1954-55: Maximum discharge during year, 700 cfs July 25 (gage height, 4.03 ft); 

no flow at times.

1955-56: Maximum discharge during year, 372 cfs May 24 (gage height, 4.88 ft); no 

flow most of time.

1956-57: Maximum discharge during year, 2,250 cfs Aug. 30 (gage height, 9.70 ft), 

from rating curve extended above 500 cfs on basis of slope-area determination at gage 

heights 8.77 and 9.25 ft; no flow most of time.

1948-57: 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 each year.

Remarks. Records poor. Most of the low flow prior to 1956 is due to leakage from an 

irrigation flume which crosses the wash a short distance upstream and return flow from 

irrigation in the immediate vicinity of the station.

Discharge, In cubic feet per second, water year October 1954 to September 1955

Records available.--May 1909 to July 1921, October 1921 to September 1927, May 1932 to 

September 1957. Monthly discharge only for some periods, published in WSP 1313.

Gage.--Water-stage recorder. Altitude of gage is 6,050 ft (from topographic map). Prior 

£o Aug. 11, 1921, staff gages and Aug. 11, 1921, to June 4, 1957, water-stage recorder 

at several sites in vicinity of present gage at different datums.

Prior to Apr. 3, 1910, staff gage and Apr. 3, 1910, to Oct. 3, 1911, water-stage 

recorder, at same site at different datum. July 27, 1927, to Dec. 19, 1931, waterstage recorder at same site at different datum.

Average discharge.--6 years (1910-11, 1927-31, 1956-57), 1,770 cfs (1,281,000 acre-ft per 

year).

Extremes. Maximum discharge during year, 20,500 cfs July 27 (gage height, 9.60 ft); minimum daily, 94 cfs Dec. 16.

1910-11, 1927-31, 1955-57: Maximum discharge determined, that of July 27, 1957; 

maximum gage height, 11.50 ft Aug. 11, 1929, site and datum then in use (discharge not 

determined); minimum daily discharge determined, 50 cfs Sept. 15, 1956.

Maximum flood known reached a stage of 12 ft, datum then in use, on Oct. 6, 1911 

(discharge estimated as 80,000 cfs). Another major flood occurred Sept. 6, 1909.

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

and those above 5,000 cfs, which are poor. Discharge measurements generally made 6 to 

8 times a month. Diversions above station for irrigation of about 52,000 acres, 2,000 

of which are below station. Records of water temperatures and suspended sediment loads 

for the water year 1957 are given in WSP 1523.

340 SAN JUAN RIVER BASIN

Animas River at Farmington, N. Mex.

Location. Lat 36°43'20", long 108°12'00", in SE£ sec. 16, T. 29 N. , R. 13 W. , on left 

bank at bridge on State Highway 17, 0.6 mile southeast of Farmington and 1.3 miles 

upstream from mouth.

Drainage area.--1,360 sq mi, approximately.

Records available.--June 1904 to October 1905 (published as "near Farmington"), September 

1912 to September 1957. Monthly discharge only for some periods, published in¥SP1313.

Gage.--Water-stage recorder. Altitude of gage is 5,278 ft (from bridge-profile plans). 

Prior to Nov. 1, 1905, chain gage at old bridge a quarter of a mile upstream at different datum. Sept. 17, 1912, to Oct. 4, 1938, water-stage recorder at site 0.6 mile 

downstream at lower datums (datum lowered 2.0 ft Aug. 15, 1927, and raised 0.2 ft 

Dec. 16, 1929) .

Average discharge. 46 years (1904-5, 1912-57), 977 cfs (707,300 acre-ft per year).

Extremes. Maximum discharge during year, 10,400 cfs July 27; maximum gage height, 7.15ft 

June 6; (gage height, 5.18 ft); minimum daily discharge not determined (probably 

occurred Oct. 1 during period of uncertain stage-discharge relation).

1904-5, 1912-57: Maximum discharge, about 25,000 cfs June 29, 1927 (gage height, 

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

logarithmic plotting; minimum daily, 2.4 cfs Sept. 5, 1956.

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 fair except those for periods of ice effect, the month of October, and 

those above 6,000 cfs, 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 suspended sediment loads for the water 

year 1957 are given in WSP 1523.

Revisions (water years). WSP 1243: 1931. WSP 1313: 1913.

348 SAN JUAN RIVER BASIN

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 1957. Monthly discharge only for some 

periods , 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 

daturns.

Average discharge.--43 years (1914-57), 2,820 cfs (2,042,000 acre-ft per year).

Extremes. Maximum discharge during year, 30,200 cfs July 29 (gage height, 18.80 ft); minimum, 21 cfs Oct. 1.

1914-17, 1927-57: Maximum discharge, 70,000 cfs Sept. 10, 1927 (gage height, 

32.0 ft), from rating curve extended above 31,000 cfs; no flow July 3-13, 1934, 

Aug. 24-27, 29, 1939.

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

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

Remarks.--Records excellent. 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 1957 are given in WSP 1523.

Revisions (water years). WSP 1213: 1940. WSP 1313: 1917, 1929. WSP 1343: 1945.

bank at head of Marble Gorge at Lees Perry, Just upstream from Paria River, 16 miles 

downstream from site of Glen Canyon Dam, 28 miles downstream from Utah-Arizona State 

line, 61.5 miles upstream from Little Colorado River, and 79 miles downstream from 

San Juan River.

Drainage area.--107.900 sq mi, approximately.

Records available. January 1895 to September 1957. Calendar year estimates and monthly 

discharge only for some periods, published in WSP 1313.

Gage.--Water-stage recorder. Datum of gage is 3,106.16 ft above mean sea level, datum of 

T929. Prior to Jan. 19, 1923, staff gages or reference points within 400 ft of present 

gage, at different daturas.

Average discharge. 46 years (1911-57), 18,240 cfs (13,210,000 acre-ft per year).

Extremes.--Maximum discharge during year, 126,000 cfs June 12 (gage height, 21.14 ft); 

minimum, 2,600 cfs Oct. 2 (gage height, 5.75 ft).

1921-57: 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,

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 oh basis of discharge computed for flood of June 18, 1921, 

for station near Grand Canyon.

Remarks.--Records excellent except those for period of ice effect, which are good. 

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. Discharge measurements generally made once a week.

Paria River at Lees Perry, Ariz.

Location--Lat 36°52'20", long 111°35'40", In NW^NEi sec. 13, T. 40 N., R. 7 E., on left 

bank half a mile upstream from mouth and 1 mile northwest of Lees Perry.

Drainage area. 1,570 sq mi, approximately. 

Records available . October 1923 to September 1957.

Gage. Water-stage recorder. Datum of gage is 3,123.40 ft above mean sea level, datum of 

1929. Prior to Oct. 5, 1925, staff gage at site 2,000 ft upstream at different datum. 

Oct. 13, 1925, to Sept. 11, 1929, staff gage at present site and datum.

Average discharge . 34 years, 30.8 cfs (22,300 acre-ft per year); median of yearly mean 

discharges, 27 cfs (19,500 acre-ft per year).

Extremes. Maximum discharge during year, 3,310 cfs Aug. 22 (gage height, 11.2 ft), from 

rating curve extended above 1,200 cfs on basis of peak discharges of 2,000 and 3,000 cfs 

computed as difference of flow of Colorado River above and below Paria River; minimum, 

0.9 cfs Dec. 24.

1923-57: Maximum discharge, 16,100 cfs Oct. 5, 1925 (gage height, 16.3 ft, present 

datum), from rating curve extended above 2,000 cfs on basis of float-area determination 

of peak flow; no flow during periods in several winters prior to 1928.

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

measurements generally made once a week. Diversions above station for irrigation of 

about 3,300 acres. Records of water temperatures and suspended sediment loads for the 

water year 1957 are given in WSP 1523.

Location. Lat 34°11'40", long 110 0 00'15", in NW£ sec. 10, T. 9 N., R. 22 E. , on right 

bank Just below Jaques Dam, 3| miles northwest of Lakeside and 4| miles southeast of 

Show Low.

Drainage area. 67.2 sq mi.

Records available. November 1941 to January 1945, June 1953 to September 1955 (monthly 

discharge only), October 1955 to September 1957. Monthly discharge only November 1941 

to January 1945, published in WSP 1313. Published as "at Jaques dam site, near Lakeside" 1941-45.

Gage. Water-stage recorder and V-notch weir. Altitude of gage is about 6,530 ft (from 

""typographic map) . November 1941 to January 1945 staff gage at site 100 ft upstream 

at different datum.

Extremes. Maximum daily discharge during year, 7.4 cfs Sept. 19 to 22; no flow 

Feb. 9-22, 28, Mar. 1, 2.

1941-45: Maximum daily discharge, 304 cfs Mar. 6, 1943 (gage height, 4.00 ft, 

datum then in use); no flow Aug. 8,9, 1943.

1953-57: Maximum daily discharge, 7.9 cfs Sept. 6-8, 1955 (gage height, 1.59 ft); 

no flow for a few days in most years.

Remarks.--Records good. Record since 1953 shows water released and seepage from Lake 

Show Low to Show Low Creek. No flow this year over spillway of Jaques Dam. Flow 

regulated by several reservoirs, largest of which are Lake Show Low, completed in 

1953; Lakeside Reservoir, completed prior to 1941; and Scott Reservoir, completed in 

1946 (combined capacity, 8,800 acre-ft). Diversions for irrigation of about 200 acres 

above Lake Show Low and diversion by pumping of floodwater stored in Lake Show Low 

to Forestdale Creek in Salt River basin (see record for Forestdale Creek diversions 

from Show Low Creek, near Show Low, Ariz.) .

Revisions. WSP 1393: Drainage area.

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. Diversion by pumping to Forestdale Creek occurred 

Mar. 21 to Apr. 11. For records of previous years see Forestdale Creek diversions 

from Show Low Creek, near Show Low. Elevations obtained weekly by Navapache Electric 

Co-operative, Inc. and once a month by Geological Survey.

1916-17, 1918-20, 1929-57: Maximum discharge, 13,000 cfs July 26, 1940; no flow 

for some days in spring or summer of most years.

Maximum discharge recorded, 25,000 cfs Dec. 5, 1919 (gage height, 12.0 ft, datum 

then in use), from rating curve extended above 2,000 cfs. Flood of Jan. 19, 1916, 

reached a stage of 12.7 ft, from floodmarks , datum then in use (discharge not detennined)i

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

which are poor. Diversions above station for irrigation of about 22,000 acres. Some 

regulation by reservoirs above station (combined capacity, about 73,000 acre-ft, not 

including Lone Pine Reservoir). Records of chemical analyses, water temperatures, 

and suspended sediment loads for the water year 1957 are given in WSP 1523.

LITTLE COLORADO RIVER BASIM 367

Little Colorado River at Holbrook, Ariz.

Location. La t 34°53'50", long 110 009'40", in SWpSWi sec. 6, T. 17 N., R. 21 E. , near 

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

downstream from Puerco 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 1957.

Average discharge. 9 years (1905-6, 1949-57), 98.7 cfs, (71,460 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, 21,800 cfs Aug. 5 (gage height, 10.96 ft); no 

flow part of each day June 21, 25, July 25.

1905-9, 1949-57: Maximum discharge determined, that of Aug. 5, 1957; 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, or doubtful or no gageheight record, which are poor. Discharge measurements generally made twice a month. 

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.

COLORADO RIVER MAIN STEM 375

Colorado River near Grand Canyon, Ariz.

Location. Lat 36°05'55", long 112°05'30", on left bank at Kaibab Bridge, a quarter of a 

mile upstream from Bright Angel Creek, 11 miles by trail northeast of Grand Canyon, 

Coconino County, 26 miles downstream from Little Colorado River, and 267 miles upstream 

from Hoover Dam.

Drainage area.--137 .800 sq mi, approximately.

Records available.--October 1922 to September 1957. 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 downstream since Dec. 9, 1922, used only for high water 

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

of 1929.

Average discharge. 35 years (1922-57), 17,240 cfs (12,480,000 acre-ft per year).

Extremes. Maximum discharge during year, 125,000 cfs June 13 (gage height, 29.1 ft); minimum, 2,860 cfs Oct. 1.

1922-57: Maximum 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; 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 1957 are given in 

WSP 1523.

376 BRIGHT ANGEL CREEK BASIN

Bright Angel Creek near Grand Canyon, Ariz.

Location.--Lat 36°05'55", long 112°05'40", on right bank 1,000 ft upstream from mouth and 

11 miles by Bright Angel trail from Grand Canyon, Coconino County.

Drainage area. 98.4 sq mi.

Records available . October 1923 to September 1957.

Gage. Water-stage recorder at present site and datum since Apr. 22, 1943. Datum of gage 

Ts 2,452.1 ft above mean sea level, preliminary datum of 1929. Oct. 20, 1923, to 

Jan. 29, 1933, and Aug. 25, 1936, to Apr. 21, 1943, staff gages at several sites within 

3,200 ft of mouth at various daturas. Jan. 30, 1933, to Aug. 19, 1936, water-stage 

recorder 200 ft upstream from present site at datum 4.5 ft higher.

Average discharge. 34 years, 36.6 cfs (26,500 acre-ft per year).

Extremes. Maximum discharge during year, 1,770 cfs Aug. 5 (gage height, 5.80 ft), from 

rating curve extended above 730 cfs on basis of slope-area determination of peak flow; 

minimum daily, 16 cfs for several days.

1923-57: Maximum discharge, 4,400 cfs Aug. 19, 1936, from rating curve extended 

above 250 cfs on basis of slope-area determination of peak flow; minimum daily, 13 cfs 

Aug. 6-9, 1954.

Remarks. Records good. Minor diversion for irrigation of a few acres above station.

Discharge measurements made once a week. Some fluctuation in flow caused by powerplant 

9 miles above station; no regulation by storage.

Revisions (water years). WSP 1213: 1941. WSP 1283: Drainage area.

382 VIRGIN RIVER BASIN

Virgin River at Littlefleld, Ariz.

Location. Lat SS-SS 1 , long 113°56', in SW£sw£ sec. 4, T. 40 N., R. 15 W., on right bank 

three-eighths of a mile downstream from Beaverdam Wash, three-eighths of a mile upstream 

from Llttlefield, and 36 miles upstream from water line of Lake Mead at elevation 

1,221 ft above mean sea level.

Drainage area. 5,090 sq mi, approximately. 

Records available . October 1929 to September 1957.

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

1929. Prior to May 28, 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. 28 years, 238 cfs (172,300 acre-ft per year); median of yearly mean 

discharge, 210 cfs (152,000 acre-ft per year).

Extremes.--Maximum discharge during year, 3,950 cfs Aug. SI (gage height, 8.00 ft); minimum, 52 cfs June 8.

1929-57: Maximum discharge, 82,000 cfs Mar. 3, 1938 (gage height, 12.8 ft, present 

datum, from floodmarks), by slope-area determination of peak flow; maximum gage height, 

13.60 ft Aug. 25, 1955; minimum observed discharge, about 50 cfs for many days in 

several years, resulting from nearby fairly uniform spring Inflow.

Remarks. Records good. Discharge measurements generally made twice a month. Diversions 

above station for Irrigation of about 23,200 acres. See measurements of discharge at 

points other than gaging stations for occasional determinations of spring Inflow In 

this vicinity. Records of chemical analyses, water temperatures, and suspended sediment loads for the water year 1957 are given In WSP 1523.

level, datum of 1929, leveling of 1950; used locally as at mean sea level, powerhouse 

datum, based on adjustment of 1912.

Extremes. Maximum contents during year, 21,737,000 acre-ft Sept. 9 (gage height, 1,184.12 

ft); minimum, 11,269,000 acre-ft Apr. 20 (gage height, 1,089.61 ft).

1935-57: Maximum contents 27,790,000 acre-ft July 29, 30, 1941 (gage height, 

1,220.45 ft); minimum (since 1940), 10,695,000 acre-ft Apr. 26, 1956 (gage height, 

1,083.21 ft).

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 and Las Vegas, Nev., area for municipal and industrial use. Discharge 

measured by venturi meters. Diversion started Apr. 7, 1942. First diversion to Las 

Vegas Valley Water District occurred October 1956. 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.

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

Colorado River Commission of Nevada.

Revisions (water years). WSP 899: 1935-39.

1942 (elevation, 412.09 ft).

Remarks. --Lake is formed by concrete-arch dam; dam was completed and storage began

 July 1, 1938. Usable capacity, 619,400 acre-ft, revised (neglecting slope in lake), 

between elevations 400.54 (sill of regulating gates) and 450.54 ft (top of regulating 

gates) above mean sea level, based on resurvey of Havasu Lake made in April 1957 by 

U. S. Bureau of Reclamation between elevations 430.54 and 450.54 ft. Dead storage, 

28,600 acre-ft below 400.54 ft (based on original survey). About 0.07 ft fall indicated between gage and Parker Dam under normal operating conditions. Drawdown below 

elevation 440.54 ft (contents, 439,400 acre-ft, revised] not legally permissible except 

by consent of the Metropolitan Water District of Southern California or in an emergency 

affecting the safety of the dam. Lake is used for flood control, power development, 

re-regulation of river for irrigation demand, and as a basin from which water is pumped 

by Metropolitan Water District of Southern California to Colorado River aqueduct.

398 DIVERSIONS FROM HAVASU LAKE

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

Location. Lat 34°19 I 00", long 114°09'25", In NW£SW£ sec. 28, T. 3 N. , R. 27 E., San

Bernardino meridian, at intake pumping plant of Metropolitan Water District of Southern 

California on Havasu Lake, 1.8 miles upstream from Parker Dam and 154 miles downstream 

from Hoover Dam.

Records available. January 1939 to September 1957 (monthly discharge only after October 

1942, see summary in WSP 1313). Published as a supplement to the records for Colorado 

River below Parker Dam, 1942-50.

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

Average discharge.--18 years, 261 cfs (189,000 acre-ft per year).

Extremes. Maximum daily diversion during year, 1,080 cfs May 8; no flow Apr. 23, 24.

IF39-57: Maximum daily diversion, that of May 8, 1957; no diversion for many periods.

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

pumped from Havasu Lake, less return surface flow from Gene and Copper Basin Reservoirs. 

No water returned as surface flow from either reservoir since 1941 except in 1953 and 

1956. During this year 4,495 acre-ft of cooling water, which is included in the record 

of diversions, was returned to Havasu 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.

COLORADO RIVER MAIN STEM 399

Colorado River below Parker Dam, Ariz.-Calif.

Location. Lat 34°15'30", long 114°09'00", in NE^SW^ sec. 16, T. 2 N. , R. 27 E. , San 

Bernardino meridian, on right bank 3.9 miles downstream from Parker Dam, 10.4 miles 

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

Drainage area.--178 ,800 sq mi, approximately.

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

records) , October 1934 to September 1957. Published as "near Parker, Ariz.," prior 

to October 1937.

Gage. Water-stage recorder. Datum of gage is 346.23 ft above mean sea level, datum of 

^1929.

Average discharge.--23 years (1934-57), 13,820 cfs (10,010,000 acre-ft per year), unadJusted; 13,860 cfs (10,030,000 acre-ft per year), adjusted to include storage in 

Havasu Lake, but not in Lake Mead and Lake Mohave.

Extremes.--Maximum discharge during year, 18,000 cfs June 25; maximum gage height, 

21.40 ft Sept. 13 and 14; minimum discharge during year, 1,960 cfs Jan. 10 (gage 

height, 17.15 ft) .

1934-57: 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 discharge, 

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 

diversion to Colorado River aqueduct and return flows see record for Colorado River 

aqueduct near Parker Dam (preceding page).

400 DIVERSIONS AND RETURN FLOWS BETWEEN PARKER DAM AMD IMPERIAL DAM

Colorado River Indian Reservation Main Canal, near Parker, Ariz.

Location.--Two gages, lat 34°10'05", long 114"16'30", in SE^NW^ sec. 31, T. 10 N., 

R. 19 W., Gila and Salt River meridian. Forebay gage, in river gate-control structure, at Arizona end of Headgate Rock Dam. Tailrace gage, 250 ft below canal intake 

gates at Headgate Rock Dam. Both gages are on Colorado River Indian Reservation, 

I? miles northeast of Parker, and 14| miles downstream from Parker Dam.

Records available.--January 1915 to September 1957 (prior to January 1937, fiscal year 

diversions only; January 1937 to September 1954, monthly diversions only).

Gage --Tape gages on intake gates to show openings, read at time of each gate change, 

water-stage recorders above and below intake gates to record head. Datum of gages is 

350.00 ft above mean sea level, datum in use locally, or 350.51 ft above mean sea 

level, datum of 1929. Normal operating level of forebay is 362.9 ft, datum in use 

locally. Prior to October 1954, discharge computed by various methods as described 

in WSP 1313.

Extremes. Maximum daily diversion during year, 794 cfs Sept. 27-30; no diversion on 

several days.

1955-57: Maximum daily diversion, 800 cfs June 25, 1955; no diversion at times in 

most years.

Remarks. Records excellent. Daily diversions computed on basis of head and gate

openings. Records show water diverted to project and surface return flows to Colorado 

River through 3 drainage canals and 2 wasteways, all of which are equipped with waterstage recorders. One drain returns flow to river between the stations, Colorado River 

below Palo Verde Dam and below Cibola Valley.

Cooperation. Record of canal intake gate opening and return surface flow to Colorado 

River furnished by Bureau of Indian Affairs.

Revisions.--Figures of diversions for 1915-36, published in WSP 879, 918, 1049, and 1313 

as calendar year diversions, were actually diversions for fiscal years ending June 30 

of indicated year.

is in Wj sec. 9, T. 15 S., R. 24 E., San Bernardino meridian; the Arizona end in 

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

upstream from Laguna Dam, PS 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 1957 (monthly 

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

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

The combined daily records of discharge obtained at gaging stations on Colorado River 

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

Dam, less that of the 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 14J miles upstream at datum 167.38 ft above 

mean sea level, datum of 1929.

Average discharge.--23 years (1934-57), 12,990 cfs (9,404,000 acre-ft per year).

Extremes. Maximum daily discharge during year, 13,700 cfs July 8, 11; minimum daily, 

2,220 cfs Jan. 13.

1934-57: Maximum discharge, 40,800 cfs Sept. 5, 1949; 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.

Monthly discharge. In cubic feet per second, year October 1956 to September 1957

GILA RIVER BASIN 407

Diversions from Glla 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 1957 (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.

Gage.--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. Water was issued 

for 6,865 acres during 1957.

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.

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

Location. Lat 33°18'00", long 109°29'30", in SE-j 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 1957.

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

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

Average discharge .--13 years, 20.3 cfs (14,700 acre-ft per year).

Extremes. Maximum discharge during year, 1,610 cfs Aug. 1 (gage height, 5.64 ft); minimum, 4.8 cfs Nov. 21.

1944-57: Maximum discharge, 7,000 cfs Jan. 13, 1952 (gage height, 8.51 ft), from 

rating curve extended above 1,9.00 cfs on basis of slope-area determination of peak 

flow; minimum, 1.5 cfs Sept. 5, 1951.

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

Diversions above station for irrigation of about 500 acres; one small diversion 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. 413).

Inflow between station and point 2-f miles downstream, below Sheep Wash, as determined by discharge measurements, was 3.0 cfs Oct. 22, 4.5 cfs Jan. 16, 3.7 cfs Apr. 25, 

and 2.5 cfs July 16. Discharge measurements or estimates, in cubic feet per second of

GILA RIVER BASIN 417

Eagle Creek above pumping plant, near Morenci, Aric.

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

bank 2| 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 1957.

Sage.--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. 13 years, 29.9 cfs (21,650 acre-ft per year); median of yearly mean 

discharges, 25 cfs (18,100 acre-ft per year).

Extremes. Maximum discharge during year, 4.S10 cfs July 26 (gage height, 6.65 ft, at 

supplementary gage); minimum, 8.9 cfs Dec. 27, result of freezeup.

1944-57: Maximum discharge, 5,340 cfs 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 2j miles 

downstream; the stage of the flood of Sept. 26, 1944, was about 2.5 ft lower at 

same site.

Remarks. Records excellent except those for periods of no gage-height record and 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, 5l| miles upstream from this station, for about three-quarters of the 

year (see p. 413). Diversions by pumping for mining, metallurgical treatment of ore, 

and domestic use in and near Morenci 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 the table below. Ninety-four percent of the pumpage 

was from Eagle Creek.

Drainage area.--2,192 sq mi.

Records available.--June 1931 to September 1932, May 1935 to September 1957. Prior to 

October 1949, published as "near Solomonsville."

Gage.--Water-stage recorder and concrete control. Datum of gage is 2,960.15 ft above mean 

sea level, datum of 1929.

Average discharge.--23 years (1931-32, 1935-57), 14.8 cfs (10,710 acre-ft per year).

Extremes. Maximum discharge during year, 8,950 cfs Aug. 30 (gage height, 18.33 ft); no 

flow for many days.

1931-57: 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 13,800 acres, mostly 

by pumping from ground water. Flood flows are partly regulated by six flood control 

detention structures on mainstream and tributaries, combined capacity in excess of 

10,500 acre-ft.

~l929. Prior to Oct. 1, 1954, at datum 3.00 ft higher.

Average discharge. 28 years, 244 cfs (176,600 acre-ft per year); median of yearly mean 

discharges, 180 cfs (130,000 acre-ft per year).

Extremes. Maximum discharge during year, 4,220 cfs Sept. 1; maximum gage height, 10.3 ft 

July 28; no flow for many days.

1929-57: Maximum discharge, 27,900 cfs Oct. 1, 1941 (gage height, 14.82 ft, present 

datum); no flow for short periods in most years.

Maximum discharge known, probably in excess of 100,000 cfs Jan. 20, 1916, computed on 

basis of peak discharge at stations near Solomon and at Kelvin.

Remarks. Records good except those above 1,000 cfs, which are fair, and those for periods 

of no gage-height record, which are poor. Discharge measurements generally made three 

times a month. Diversion above station for metallurgical treatment of ores, municipal 

uses, and irrigation of about 69,000 acres, partly by pumping from ground water.

of 1929. Prior to Jan. 11, 1911, staff gage at former railroad bridge, 10 miles downstream at different datum. Apr. 26, 1914, to July 31, 1915, water-stage recorder at 

site 9| miles downstream and Nov. 14, 1929, to Jan. 31, 1942, water-stage recorder at 

site 4 miles downstream, both at different datum.

Average discharge.--28 years (1929-57), 45.7 cfs (33,090 acre-ft per year); median of 

yearly mean discharges, 28 cfs -(20,300 acre-ft per year).

Extremes. Maximum discharge during year, 7,310 cfs July 26 (gage height, 9.2 ft); no 

flow for many days.

1929-57: Maximum discharge, 40,600 cfs Mar. 14, 1941 (gage height, 11.4 ft, site 

and datum then in use), from rating curve extended above 23,000 cfs on basis of rate 

of change in storage in San Carlos Reservoir; no flow for some days in most years.

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

Discharge measurements generally made three times a month. Diversions above station 

for irrigation of about 600 acres.

Coolidge Dam" 1927-38.

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, waterstage recorder at various sites within 1 mile upstream from present site at different 

datums.

Average discharge (adjusted for storage in San Carlos Reservoir).--45 years (1900-1901, 

1903-4, 1914-57), 365 cfs (264,200 acre-ft per year); median of yearly mean discharges, 

220 cfs (159,000 acre-ft per year).

Extremes . Maximum discharge during year, 509 cfs July 31 (head on flume, 2.56 ft); minimum daily, 0.6 cfs for many days.

1914-57: 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. 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 during the 1957 water year as 0.70 cfs 

on Feb. 19, 0.88 cfs on May 3, and 0.78 cfs on June 12.

Discharge measurement made on this day.
GILA RIVER BASIN 431

Gila River at Winkelman, Aric.

Location.--Lat 33°00'10", long 110°45'55", in NW^NE^ sec. 13, T. 53., R. 15 E., on right 

bank 1-j 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, December 1928 to February 1935 (discharge 

measurements only), September 1941 to September 1957.

Gage.--Water-stage recorder at present site since Sept. 11, 1941. Datum of gage is 

TT,920.95 ft above mean sea level, datum of 1929, supplementary adjustment of 1949. 

September- 1917 to June 27, 1918, chain gage at bridge 1.5 miles downstream at different 

datum.

Average discharge. 16 years (1941-57), 171 cfs (123,800 acre-ft per year); median of 

yearly mean discharges, 137 cfs (99,200 acre-ffc per year), adjusted for storage in San 

Carlos Reservoir.

Extremes. Maximum discharge during year, 1,270 cfs Aug. 12 (gage height, 5.76 ft); minimum, no flow for many days.

1941-57: 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 at times in summer and fall 

when Coolidge Dam is closed.

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

Large diversions above station for irrigation, metallurgical treatment of ore, and 

municipal supply, but none between Coolidge Dam and this station. About 69,000 acres 

irrigated in the basin above Coolidge Dam, a considerable portion by pumping from 

ground water. Flow regulated by San Carlos Reservoir (see p. 429). Discharge measurements generally made three times a month during release from Coolidge Dam and twice a 

month the remaining parts of the year.

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 (adjusted for storage in San Carlos Reservoir).--46 years (1911-57), 

493 cfs (357,600 acre-ft per year); median of yearly mean discharges, 346 cfs 

(250,000 aere-ft per year).

Extremes. Maximum discharge during year, 4,540 cfs Aug. 19 (gage height, 7.12 ft); minimum daily, 0.1 cfs July 14-19.

1911-57: 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 for several years.

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

height, 12 .6 ft) .

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

Discharge measurements generally made 3 times a month during release from Coolidge Dam 

and 2 times a month during the remaining periods. Large diversions above station for 

irrigation, of which about 90 percent is above Coolidge Dam. About 78,000 acres irrigated (in 1955), a considerable portion by pumping from ground water. Flow regulated 

by San Carlos Reservoir (Coolidge Dam) since Nov. 15, 1928 (see p. 429); no other regulation. San Pedro River contributes major portion of unregulated inflow. Records of 

chemical analyses and water temperatures for the water year 1957 are given in WSP 1523.

GILA RIVER BASIN 437

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

Location. Lat 33°06'00", long 111°14'50", in SW^NW^ sec. 8, T. 43., R. 11 E., on left 

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

Drainage area. 18,305 sq mi.

Records available.--July 1923 to September 1957 (head on crest of dam only). Records of 

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

1957.

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

aatum of 1929. Crest height was about 1.17 ft higher by use of flashboards. Prior 

to Apr. 12, 1932, chain gage at same site and datum. Water-stage recorder and Parshall flume on Florenee-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 Ashurst-Hayden Dam.

Extremes.--Maximum head on dam during year, 1.87 ft Aug. 19; no flow over dam greater 

part of year.

1923-57: 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 Florence-Casa 

Grande Canal. Mean head is often net 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 78,000 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.

Correction. The daily mean head for July 31, 1955, was 0.67 ft, superseding erroneous 

figure published in WSP 1393.

Daily mean head, in feet, water year October 1956 to September 1957

GILA RIVER BASIN 445 

Tucson Arroyo at Vine Avenue, Tucson, Ariz.

Location.--Lat 32°13'00", long 110°57'00", in SW^NE^ sec. 18, T. 14 S., R. 14 E., on right 

bank at Vine Avenue, a quarter of a mile downstream from Arroyo Chico and 2-J- miles 

upstream from mouth.

Drainage area. Original area prior to August 1945, 27.0 sq mi; subsequently reduced to 

following areas by flood-control diversion structures: 1945-53, 23.4 sq mi; 1953-54, 

18.1 sq mi; 1954 to June 1956, 15.9 sq mi; since June 1956, 8.2 sq mi. The contributing area above an overflow spillway on main interceptor canal is not included in 

the latter area. See Remarks.

Records available.--June 1944 to September 1957.

Gage. Water-stage recorder and concrete control. Datum of gage is 2,411.9 ft above 

mean sea level (city of Tucson benchmark).

Average discharge. 8 years (1945-53), 0.68 cfs (492 acre-ft per year), representing 

flow from 23.4 sq mi.

Extreme s.--Maximum discharge during year, 716 cfs July 17 (gage height, 6.29 ft); no 

flow most of year.

1944-57: Maximum discharge, 4,100 cfs July 24, 1948 (gage height, 9.9 ft), from 

rating curve extended above 1,800 cfs on basis of conveyance-extension determination 

of peak flow; no flow most of each year.

Remarks.--Records good. A flood-control project diverted runoff from upper end of basin 

into a flood-control detention reservoir in SE-f sec. 29, T. 14 S., R. 14 E. , from 

which reservoir water is released to Julian Wash, which enters Santa Cruz River 

upstream from Tucson Arroyo. Runoff was from 15.2 sq mi. Maximum temporary storage 

during year occurred Aug. 22-23 or Aug. 31 to Sept. 1, negligible storage during 

remainder of year. An overflow spillway was constructed on main interceptor canal 

last year in NE^SW-f sec. 22, T. 14 3., R. 14 E.; this will allow overflow to Tucson 

Arroyo when canal discharge exceeds about 1,000 cfs.

September 1957.

Gage. Water-stage recorder. Datum of gage is 2,137.13 ft above mean sea level (Arizona 

Highway Department benchmark). Prior to June 30, 1947, at site 4f miles downstream 

at different datum.

Average discharge. 14 years (1939-46, 1950-57), 28.5 cfs (20,630 acre-ft per year); 

median of yearly mean discharges, 22.4.cfs (16,200 acre-ft per year).

Extremes.--Maximum discharge during year, 4,400 cfs Sept. 1 (gage height, 5.69 ft); no 

flow for many days.

1939-47, 1950-57: Maximum discharge, 17,000 cfs Aug. 14, 1940 (gage height, 9.9 ft, 

site and datum then in use); no flow most of each year.

Remarks.--Records fair. Many diversions above station, mostly by pumping from ground 

water for irrigation of about 34,000 acres. Waste water from irrigation and from 

sewage disposal plant occasionally causes flow past station during dry periods, but 

is not included in this record.

GILA RIVER BASIN 453

Santa Cruz River near Laveen, Ariz.

Location (revised). Lat 33 0 13'56", long 112°10'08", in NE^NE^ sec. 29, T. 2 S., R. 2 E., 

in Gila River Indian Reservation, on downstream side of highway bridge 4.3 miles south 

of Komatke, 3.4 miles upstream from mouth, and 9 miles south of Laveen.

Drainage area. 8,581 sq mi.

Records available. January 1940 to September 1946, December 1947 to September 1957.

Gage. Water-stage recorder. Datum of gage is 1,020.86 ft above mean sea level, datum of 

T929, Phoenix-Picacho supplementary adjustment of 1949.

Average discharge 15 years (1940-46, 1948-57), 22.0 cfs (15,430 acre-ft per year); 

median of yearly mean discharges, 14 cfs (10,100 acre-ft pep year).

Extremes. Maximum discharge during year, 1,040 cfs Aug. 20 (gage height, 12.40 ft); no 

flow for many days.

1940-46, 1947-57: Maximum discharge, 5,060 cfs (including an estimated 1,000 cfs 

in overflow channel bypassing gage), Aug. 28, 1951 (gage height, 17.00 ft); no flow at 

times in 1950-51, 1954-57, and negligible seepage flow amounting to less than 0.05 cfs 

in 1940, 1948-49.

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

Many diversions above station, mostly by pumping from underground basin, for municipal 

uses and for irrigation of about 240,000 acres, not including San Carlos project. 

Much of low flow at times is drainage and wasteway return from irrigated lands upstream.

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

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

Drainage area.--6.211 sq mi, at Stewart Mountain Dam.

Records available . April 1910 to September 1957 (prior to October 1934, contents at end 

of each month only, published in WSP 1049 and 1313).

Gages. Roosevelt Lake, water-stage recorder; Apache Lake, water-stage indicator in powerpTant connected to long distance transmitter on lake since April 1949; prior to that 

date, staff gage or reference mark; Canyon and Saguaro Lakes, mercury column gages.

1910-57: 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 4 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; Saguaro

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,

Fossil Creek diversions to Childs powerplant, near Camp Verde, Ariz.

Location. Lat 34°22'05", long 111°39'55", in NE^SW^ sec. 20, T. llj N., R. 7 E., at 

head of Stehr Lake, 2-5- miles northeast of Childs powerplant, 4.4 miles by flume downstream from Irving powerplant, and 17| miles southeast of Camp Verde.

Records available.--January 1952 to September 1957.

Extremes. 1952-57: 

in most years.

Maximum daily discharge, 51 cfs Apr. 17-21, 1952; no flow at times

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

and shows the water used Dy Childs powerplant. Most of the 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 the flume below Irving plant and was measured as follows: 

Nov. 4, 0.77 cfs; Nov. 27, 0.76 cfs; Jan. 22, 1.38 cfs; June 14, 0.78 cfs; July 10, 

0.78 cfs; Aug. 14, 1.06 cfs, and Sept. 16, 0.39 cfs. Based on these measurements, 

observations of no 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.

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 periods of no gage-height record and those 

above 3,300 cfs, which are good. Diversions above station for irrigation of about 

12,500 acres, some of which are 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.

GILA RIVER BASIN 475 

Agua Fria River at Lake Pleasant Dam, Ariz.

Location.--Lat 33°51' , long 112 0 16', in NW£ sec. 21, T. 6 N. , R. 1 E., at left upstream 

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

New River.

Drainage area.--1,459 sq mi.

Records available.--November 1910 to September 1914 (gage heights only), October 1914 to 

September 1919, October 1919 to September 1924 (gage height only), October 1933 to September 1957 (monthly discharge only). Published as "near Glendale" prior to 1920.

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

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

recorder at several sites in the vicinity of diversion dam l£ miles downstream from 

Lake Pleasant Dam, at different datum.

Average discharge.--29 years (1914-19, 1933-57), 94.7 cfs (68,560 acre-ft per year); 

median of yearly mean discharge, 47.3 cfs (34,240 acre-ft per year).

Extremes.--1910-24 . 1933-57; Maximum discharge, about 105,000 cfs Jan. 28, 1916 (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 

summers of several years.

Remarks. Records fair. Figures given herein represent flow into Lake Pleasant. Discharge computed on basis of three factors as follows- 1. Change in contents of Lake 

Pleasant and in contents of small reservoir behind diversion dam 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 sinoe May 13, 1941). 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 11 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 themsleves, may result 

in disproportionally large inaccuracies in small figures of inflow computed as residuals. Diversions for irrigation above Lake Pleasant of probably not over 1,000 acres. 

Records of chemical analyses and water temperatures for the water year 1957 are given 

in WSP 1523.

Cooperation.--Records collected and prepared In cooperation with Maricopa County Municipal 

Water Conservation District No. 1.

Location. Lat 33°51', long 112 c'16' , In Mi; sec. 21, T. 6 N., R. 1 E., at left upstream 

end of Lake Pleasant Dam on Agua Pria River.

Drainage area. 1,460 sq mi, approximately.

Records available. February 1928 to September 1957 (yearly data only, prior to 1939).

Gage. Staff gage read twice daily. Datum of 

aatum of 1929.

a;e is 1,431.2 ft above mean sea level,

Extremes. Maximum contents during year, 25,160 acre-ft Mar. 21 (gage height, 106.53 ft); 

minimum, 3,170 acre-ft Sept. 29, 30.

1928-57: 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 (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.

Buckeye Canal near Avondale, Ariz.

Location.--Lat 33°23'40", long 112°22'25", in SW^-SW^ sec. 28, T. 1 N. , R. 1 W. , on left

bank 0.3 mile 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.--May 1953 to September 1957.

Gage.--Dual water-stage recorder and Parshall flume. Datum of gage is 904.62 ft above 

mean sea level, datum of 1929, supplementary adjustment of 1949.

Extremes. Maximum daily discharge during year, 108 cfs Aug. 21; no flow for many days. 

TS53-57: Maximum daily discharge, 257 cfs Aug. 8, 1954; no flow for several days 

in 1953, 1956-57.

Remarks. Records excellent above 10 cfs and good below. Canal diverts from right bank 

oFTJila River in SEjj-SWi sec. 28, T. 1 N., R. 1 W. , for irrigation in the Buckeye area. 

Total acreage this year in the Buckeye Irrigation District is 17,700 acres. Record 

includes waste water and flow from canals of Salt River project, delivered through 

Buckeye feeder ditch to the Gila River channel in SWrNW^ sec. 34, T. 1 N., 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. Record of Buckeye feeder ditch furnished by Salt River Valley Water Users' 

Association.

only;; ror Enterprise canal June I93b to September laaa idiscnarge measuremens easurements and 

monthly estimates only), October 1939 to September 1957 (since October 1941, monthly 

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

June 1935 to September 1957.

crest of dam.

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

Enterprise Canal: Water-stage recorder since Nov. 29, 1929, 600 ft downstream from 

intake .

Average discharge (river below dam) .--16 years (1941-57), 29.3 cfs (21,210 acre-ft per 

year) ; median or yearly mean discharges , 15 cfs (10,900 acre-ft per year).

Extremes. Maximum discharge over dam during year, 205 cfs Jan. 29 (gage height, 10.14 ft): 

Approximate inflow during this period was 250 cfs. A peak discharge of 959 cfs 

occurred Jan. 13 during sluice period, all of which was from storage behind dam. 

Estimated peak inflow did not exceed 250 cfs. No flow most of year.

1921-57: Maximum discharge observed, 85,000 cfs Dec. 28, 1923 (gage height, 

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

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

Remarks . 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) . During calendar year 1956, there was no flow below the dam.

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

and for monthly records of Gila Bend Canal and Enterprise Canal see tables below. 

Records of combined flow are fair. Records of chemical analyses and water temperatures 

for the water year 1957 are given in WSF 1523.

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

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

Verde Canal, Ail-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, Reservation Canal Main Drain No. 4, Drain 8-B, and Pilot Knob 

wasteway See monthly table below for combined flow of river, Yuma Main Canal wasteway, and Reservation Canal Main Drain No. '4. Flow of Colorado River regulated by 

Hoover, Da vis, 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 twice a week.

DIVERSIONS AND RETURN FLOWS AT AND BELOW IMPERIAL DAM

Yuma Main Canal at siphon-drop powerplant , near Yuma , Aris .

Location. La t 32°46'35" , long 114°38'05", in SE^SE^ sec. 10, T. 16 S., R. 22 E., San 

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

downstream from intake of Ail-American Canal at Imperial Dam.

Records available .--July 1926 to September 1957. Monthly discharge only for some periods, 

published in WSP 1313. Diversions from Ail-American Canal and Yuma Main Canal above 

siphon-drop powerplant, October 1947 to September 1957 (monthly discharge only). 

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

wasteway, October 1940 to September 1957 (monthly discharge only).

Gage . --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. 30, 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 wells. Since Sept. 15, 1952, water-stage recorder operated on 

forebay by Bureau of Reclamation.

Average discharge . --31 years, 1,702 cfs (1,232,000 acre-ft per year).

Extremes . --Maximum daily discharge during year, 1,980 cfs Sept. 22; minimum daily, 10 cfs 

Jan. 7-10.

1930-57: Maximum daily discharge. 2,040 cfs Nov. 11, 1943; no flow on some days 

in 1937-39, 1945.

Remarks , --Records excellent except those for period of leakage, which are poor. 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 determined from relationship of forebay elevation and gate openings as logged by powerplant operators. Rating of turbines and bypass flow checked 

by two or more discharge measurements a month. Flow regulated by gates from AilAmerican Canal to Yuma Main Canal. Records show quantity of water diverted from AilAmerican 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, 3-jj- miles downstream.

The combined diversions by several small canals from the Ail-American Canal 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. These diversions used 

tD irrigate about 10,800 acres on the Bard and Indian Units of the Reservation Division of the Yuma project in California.

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

Reeclamation .

Yuma Main Canal wasteway at Yuma, Ariz.

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

lat 32°44'00" , long 114°37'20", 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-jj 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.

Reoords available. April 1913 to September 1957. Monthly discharge only for some periods, 

published in WSP 1313.

Average discharge.--29 years (1928-57), 1,244 cfs (900,600 acre-ft per year).

Extremes. Maximum daily discharge during year, 1,740 cfs Aug. 5; minimum daily, 5 cfs 

Dec. 18-22, Jan. 1, 7-10, 18, 19.

1930-57: Maximum daily discharge, 2,020 cfs Dec. 24, 25, 1948; no flow for several 

days in 1937-39, 1945, 1950.

Remarks. Records excellent except those between 50 and 900 cfs, which are good, and those 

below 50 cfs, 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 Reservation Canal Main Drain No. 4 which 

discharges into the wasteway a quarter of a mile above its mouth.

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

of Reclamation.

490 DIVERSIONS AND RETURN PLOWS AT AND BELOW IMPERIAL DAM

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 SWijSE^ 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 powerplant. 

At outlet, in NW-^NE-j 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 upper highway 

bridge over Colorado River at Yuma.

Records available. January 1924 to September 1957. Monthly discharge only for some 

periods, published in W3P 1313. Diversion from Yuma Main Canal for municipal supply 

for Yuma, October 1947 to September 1957 (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. 33 years, 474 cfs (345,300 acre-ft per year).

Extremes. Maximum daily discharge during year, 788 cfs Aug. 3; no flow all or part of 

each day Jan. 6-11.

1930-57: Maximum daily discharge, 883 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 generally made every two weeks. Records show quantity of water 

delivered through Colorado River siphon for irrigation of 45,360 acres in the Valley 

Division of the Yuma project and for supplementary municipal supply for City of Yuma. 

Records of chemical analyses for the water year 1957 are given in WSP 1523.

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

furnished by Arizona Public Service Co.

492 DIVERSIONS AND RETURN FLOWS AT AND BELOW IMPERIAL DAM

Pilot Knob powerplant and wasteway near Pilot Knob, Calif. 

(Formerly published as Pilot Knob wasteway near Pilot Knob, Calif.)

Location. Lab 32°44'15", long 114°42'55", in NW£SW£ sec. 25, T. 16 S., R. 21 E., San

Bernardino meridian, 2 miles east of summit of Pilot Knob, 6 miles west of Yuma, Ai-iz. , 

and 20.8 miles downstream from intake of All-American Canal at Imperial Dam.

Records available.--February 1939 to September 1957. Prior to October 1956, published as 

Pilot Knob wasteway near Pilot Knob, Calif. Prior to October 1943, monthly discharge 

only, published in WSP 1313.

Gage. Water-stage recorder on right bank of All-American Canal, 550 ft upstream from 

wasteway gates and 1,800 ft from entrance of powerplant. Tailrace gage is on left 

bank 680 ft below powerplant with automatic recording equipment in control house. All 

by-pass gates are equipped with calibrated openings which are read on all gate changes. 

Datum of forebay and tailrace gage is at mean sea level, datum of 1929. Elevation of 

sill of wasteway gates is 147.88 ft, datum of 1929.

Extremes.--Maximum daily discharge during year, 3,040 cfs Sept. 10; no release most of 

year when wasteway gates closed except for leakage estimated about 10 cfs to Dec. 31. 

Leakage negligible after gate seals replaced on Dec. 31.

1939-57: Maximum daily discharge, 4,650 cfs Aug. 10, 1950; no flow during long

periods.

Remarks. Records excellent above 2,000 cfs, good 2,000 to 1,200 cfs, and poor below 1,200. 

Daily discharge computed from head, gate openings on wicket, and wasteway gates used 

with rating based on current meter measurements. Records show water released through 

Pilot Knob powerplant and wasteway from All-American Canal and which is returned to 

Colorado River through Rockwood gates. Pilot Knob wasteway completed in summer of 

1938 and first flow occurred Feb. 5, 1939. Pilot Knob powerplant was completed in 

January 1957 and first flow occurred Jan. 14, 1957. Leakage through wasteway gates 

when closed since April 1953, has been about 10 cfs and has not been included in any 

records published except period Sept. 10-17, 1956, when there was flow through automatic bypass gates. Replacement of gate seals on Dec. 31, 1957, reduced this leakage 

to a negligible quantity thereafter.

For records of combined return flow to Colorado River by Pilot Knob powerplant and 

wasteway, and for monthly return flow by wasteway only, see tables below.

Cooperation. Recorder graph of forebay, record of tailrace elevation and gate openings, 

furnished by Imperial Irrigation District.

a No gage-height record; discharge estimated on basis of high-water mark, weather records,

DISCHARGE MEASUREMENTS AT POINTS OTHER THAW GAGING STATIONS 497

Measurements of streamflow made at points other than regular gaging stations in the 

area covered by this report 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. Measurements believed to have been made under base-flow conditions are identified by an asterisk^*) to the left of the discharge figure. 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. The column headed, 

"Measured previously" shows the water years in which measurements were made at the same, 

or practically the same, site.

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

a separate table on page 501.
