SURFACE WATER SUPPLY OF THE COLORADO RIVER BASIN, 1958

SCOPE OF WORK

This volume is one of a series of 18 reports presenting measurements of stage, discharge , and content of streams, lakes, and reservoirs in the United States during the 

water year ending September 30, 1958. 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 14,000 gaging stations in the 48 States and at many 

others in the Territories of Alaska and Hawaii. On September 30, 1958, the Geological 

Survey and cooperating organizations were maintaining 7,090 gaging stations, including 

those in Alaska and Hawaii. Partial-record stations for low flow or for flood flow have 

been operated at many other points. In addition, discharge measurements are made at miscellaneous sites. The records for the water year October 1, 1957, to September 30, 1958, 

at gaging stations, partial-record stations, and miscellaneous sites in the Colorado River 

basin are given in this report.

Information of a more detailed nature than that published for most of the gaging stations given in this report is on file in the district offices listed above. Some gagingstation records for the Upper Colorado River basin have been analyzed by electronic computer to give the number of days in each year that the daily discharge was between 

selected limits (duration tables). Provisional records of discharge, information on the 

availability of electronic computer results, and other unpublished data concerning the 

gaging-station records may generally 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:

Gaging station is a particular site on a stream, canal, lake, or reservoir where 

systematic observations of gage height or discharge are obtained. When used in connection 

with a discharge record, the term is applied herein only to those gaging stations where a 

continuous record of discharge is obtained.

Partial-record station is a particular site where limited streamflow data are collected 

systematically over a period of years for use in hydrologic analyses.

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.
DOWNSTREAM ORDER AND STATION NUMBERS 3

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 (in.) shows the depth to which the drainage area would be covered if 

all the runoff for a given time period were uniformly distributed on it.

Acre-foot (ac-ft) is the quantity of water required to cover an acre to the depth of 

1 foot and is equivalent to 43,560 cubic feet.

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 stagedischarge 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 AND STATION NUMBERS

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

order of listing gaging-station records was changed. In this report, in a downstream 

direction along the main stem all stations on a tributary entering above a main-stem 

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

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

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

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

tributary, each indention in the listing of gaging stations in the table of contents of 

this report represents one rank. This downstream order and system of indention show 

which gaging stations are on tributaries between any two stations on a main stem and the 

rank of the tributary on which each gaging station is situated.

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

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

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

from source to mouth of the uppermost tributary to the tributary.

As an added means of identification, each gaging station and partial-record station 

has been assigned a station number. The numbers have been assigned in the same downstream 

order used in this report. In assigning station numbers, no distinction is made between 

partial-record stations and regular gaging stations, so that the station number for a 

partial-record station indicates downstream-order position in a list made up of both types
4 SURFACE WATER SUPPLY, 1958, PART 9

of stations. Gaps are left in the numbers to allow for new stations that may be 

established; hence the numbers are not consecutive. The complete number for each station 

has eight digits, but the station number as shown in this report, Just to the left of the 

station name, consists of only the essential digits of the complete number. For example, 

for a station with the complete number 09-0100.00, the station number shown in this report 

is 100. The notation in the two places to the left of the hyphen is the part number; it 

is 9 for all stations in this report and is therefore omitted.

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.

Rating tables giving the discharge for any stage are prepared from stage-discharge 

relation curves defined by discharge measurements. If extensions to the rating curves are 

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

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

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

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

tables gives the daily mean discharge, from which the monthly and the yearly mean discharge are computed. If the stage-discharge relation is subject to change because of frequent or continual change In the physical features that form the control, the daily mean 

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

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

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

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

the daily mean discharge is computed by what is essentially the shifting-control method.

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

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

method in which the slope or fall in a reach of the stream is a factor in determining discharge. Information requisite for determining the slope or fall is obtained by means of 

an auxiliary gage set at some distance from the base gage. At some stations the stagedischarge relation is affected by changing stage. If so, the rate of change In stage is 

used as a factor in the determination of discharge.

At most gaging stations in the northern part of the United States and at some in the 

mountainous regions of other parts the stage-discharge relation is affected by ice during 

the winter, and it becomes impossible to compute the discharge in the usual manner. Discharge for periods of ice effect is computed on the basis of the gage-height record and 

occasional winter discharge measurements, consideration being given to the available 

information on temperature and precipitation, notes by gage observers and engineers, and 

comparable records of discharge for other stations in the same or nearby basins. If the
EXPLANATION OP DATA 5

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 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 1958 is shown on page IV for the purpose 

of finding the day of the week Cor 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 

daturas 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 fewe^ than five complete years of record or for stations where changes in 

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

Under "Extremes" are given the maximum discharge and gage height; the minimum discharge if 

there is little or no regulation; the minimum daily discharge if there is extensive 

regulation (also the minimum discharge if useful); and the minimum gage height (unless it 

is of no importance). In the first paragraph, the data given are for the complete current 

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

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

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

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

last paragraph under "Extremes." Unless otherwise qualified, the maximum discharge corresponds to the crest stage obtained by use of a water-stage recorder, a crest-stage 

indicator, or a nonrecording gage read at the time of the crest. If the maximum gage 

height did not occur at the same time as the maximum discharge, it is given separately. 

Information pertaining to the accuracy of the records and conditions which affect the 

natural flow at the gaging station is given under "Remarks."

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

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

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

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

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

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

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

1932, to September 30, 1933. If no daily, monthly, or annual figures of discharge are 

concerned in the revision, that fact is brought out by notations after the year dates as

53970Z O -60 -Z
6 SURFACE WATER SUPPLY, 1958, PART 9

follows: "(M)" means that only the Instantaneous maximum discharge was revised; "(m)" 

that only the instantaneous minimum was revised; and "(P)" that only peak discharges were 

revised. If the drainage area has been revised, the report in which the revised figure 

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

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

drainage area necessitates corresponding revision of all figures based on the drainage 

area. Revised figures of cubic feet per second per square mile and runoff in inches 

resulting from a revision of the drainage area only are usually not published in the 

annual series of reports.

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

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

not published for stations on canals.

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

sudden or rapid fluctuation, the daily table gives the discharge corresponding to the 

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

height may not indicate the true daily mean discharge, which must be obtained by averaging 

the discharge for parts of the day or by using the discharge integrator, an instrument for 

obtaining the daily mean discharge from a continuous gage-height graph and containing, as 

an essential element, a curve representing the stage-discharge relation at the station. 

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

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

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

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

station description.

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

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

first day of its occurrence.

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. Discharge 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 noncontributlng areas, or if the average annual rainfall over the drainage 

basin is usually less than 20 inches.

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

daily discharges, not the momentary discharges when the water was at crest stage. Likewise, the minlmums 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
ACCURACY OP FIELD DATA AND COMPUTED RESULTS 7

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.

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 quality-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 

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

reported in the quality-of-water annual reports.

Data collected at partial-record stations and at miscellaneous sites are given at the 

end of each report. Partial-record stations are presented in two tables. The first is a 

table of discharge measurements at low-flow partial-record stations, and the second is a 

table of annual maximum stage and discharge at crest-stage stations. Discharge measurements at miscellaneous sites are given in a third table. Occasionally, a series of discharge measurements are made within a short time period to investigate the seepage gains 

or losses along a reach of a stream or to determine the low-flow characteristics of an 

area. Such measurements are given in special tables after the list of measurements at 

miscellaneous sites.

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.
8 SURFACE WATER SUPPLY, 1958, PART 9

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.

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

natural runoff, owing to diversion, consumption, regulation by storage, increase or 

decrease in evaporation due to artificial causes, or to other factors. For such stations, 

figures of cubic feet per second per square mile and of runoff in inches are not published 

unless satisfactory adjustments can be made for diversions, 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 1.

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 1940, from 4 areas of 

less than 800 acres, and near Tombstone, Ariz., beginning in 1954, from 5 areas ranging 

from 594 to 38,400 acres. Also, the Agricultural Engineering Department, University of 

Arizona began collecting records in 1956 on an unnamed tributary to Pantano Wash, sec. 28, 

T. 14 S., R. 15 E., half a mile upstream from mouth and 9j miles east of Tucson, Ariz.

HYDROLOGIC CONDITIONS

Runoff during the 1958 water year was above median in the upper basin except during 

July to September when runoff was deficient over most of this part of the basin. In the 

lower basin, streamflow ranged from excessive in the northern part to deficient in the 

southern part during October to January; well above median during February to June and 

September; and deficient during July and August. No noteworthy floods occurred during 

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 1958 water year with the 

median discharges for the 25-year period 1921-45 is shown in figure 2 on the following

FRASER RIVER BASIN 25

250. Vasquez Creek near Winter Park, Colo.

Location. Lat 39"55"15", long 105°47'05", in NW£ sec. 33, T. 1 S., R. 75 W., on right 

bank 40 ft downstream from bridge on U, S. Highway 40, a quarter of a mile upstream 

from mouth, 2^ miles northwest of Winter Park, 2j miles southeast of Fraser, and 

3? miles downstream from Moffat water tunnel diversion.

Drainage area. 27.8 sq mi.

Records available. June 1907 to October 1909 (irrigation seasons only), October 1933 to 

September 1958. Published as Vasquez River at lower station, near Fraser 1907-9 and 

as "near West Portal" 1934-39. Records since May 26, 1937, equivalent to earlier 

records if diversion to Moffat water tunnel is added to flow past station.

Gage. Water-stage recorder and concrete control. Datum of gage is 8,768.48 ft above 

mean sea level, unadjusted. June 1, 1907, to Oct. 31, 1909, staff gage at site threequarters of a mile upstream at different datum.

Average discharge. 25 years (1933-58), 32.4 cfs (23,460 acre-ft per year), including 

diversions to Moffat water tunnel.

Extremes. Maximum discharge during year, 275 cfs May 23 (gage height, 2.68 ft); minimum 

daily, 0.1 cfs July 15-20.

1933-58: Maximum discharge, 470 cfs June 10, 1952 (gage height, 3.13 ft), from 

rating curve extended above 340 cfs; no flow at times in 1944, 1946, 1956.

Remarks. Records good except those below 9 cfs and those for periods of ice effect or 

no gage-height record, which are poor. Transmountain diversions above station to 

Moffat water tunnel (see p. 329) was 5,530 acre-ft during water year 1958.

Cooperation. Records of flow diverted to Moffat water tunnel furnished by State engineer.

Rating tables, water year 1957-58, except periods of Ice effect (gage height, In

feet, and discharge, In cubic feet per second)

Note . Stage-discharge relation affected by Ice Nov. 18, 22, 23, Nov. 28 to Dec. 6, Dec. 8, 

Jan. 1-11, Feb. 28 to Mar. 6, Mar. 10, 11.
GUKNISON RIVER BASIN 123 

1525. Gunnison River near Grand Junction, Colo.

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

left bank of river and right bank of canal half a mile downstream from point of diversion of Redlands power canal and 5 miles upstream from mouth and Grand Junction.

Drainage area.--8.020 sq mi, approximately.

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

September 1899, October 1901 to October 1906, October 1916 to September 1958. Monthly 

discharge only for some periods, published in WSP 1313. Published as "at Whitewater" 

1901-6.

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

.atum of 1929. Prior to Apr.'l, 1917, staff or chain gages at several sites 1? miles 

downstream near mouth and 12 Biles upstream at Whitewater at various datums. Apr. 1, 

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

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

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

different datum.

Average discharge (combined flow). 50 years (1896-99, 1901-6, 1916-58), 2,689 efs 

(17947,000 aere-ft per year).

Extremes (combined flow) . Maximum discharge during year, 20,400 cfs May 24; minimum 

daily, 456 cfs Aug. 15.

1896-99, 1901-6, 1916-58: Maximum discharge observed, 35,700 efs May 23, 1920 

(gage height, 14.95 ft), from rating curve extended above 22,000 efs; minimum daily, 

106 efs July 20, 1934.

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

which are fair. Redlands power canal diverts water above river station and returns it 

to Colorado River below mouth of dunnison River. Records show combined flow of river 

and Redlands power canal and except for about 40 cfs diverted below gage during irrigation season represents entire flow that enters Colorado River from Gunnison River 

basin. Natural flow of river affected by diversions for irrigation of about 233,000 

acres above station, small diversions out of basin, small storage reservoirs, and 

return flow from irrigated lands. Records of chemical analyses and water temperatures 

for the water year 1958 are given in WSP 1574.

Location. Lat 40°34'50", long 109°37'20", in SE£ sec. 1, T. 3 S., R. 20 E., on left 

bank three-quarters of a mile upstream from head of Utah Power & Light Co.'s canal, 

4f miles upstream from Dry Pork, and 10 miles northwest of Vernal.

Drainage area. 101 sq mi.

Records available.--October 1911 to April 1912, August to December 1912, October 1913 to 

September 1958. Monthly discharge only for some periods, published in WSP 1313.

Gage. Water-stage recorder. Altitude of gage is 6,250 ft (from river-profile map). 

Prior to June 6, 1914, staff gages at site If miles downstream at different datums. 

June 6, 1914, to Nov. 13, 1917, staff gage or water-stage recorder at site a quarter 

of a mile downstream at different datums.

Average discharge.--45 years (1913-58), 104 cfs (75,290 acre-ft per year).

Extremes. Maximum discharge during year, 980 cfs May 24 (gage height, 2.30 ft); minimum, 

21 cfs Apr. 1.

1911-58: Maximum discharge, 2,050 cfs May 29, 1921 (gage height, 8.23 ft, site 

and datum then in use), from rating curve extended above 860 cfs; minimum,13 cfs 

Apr. 26, 1957.

Remarks. Records excellent. Flow is increased by water released from Oaks Park Reservoir (capacity, 6,250 acre-ft) on Brush Creek and diverted to Ashley Creek basin for 

irrigation (see p. 217). City of Vernal pipeline (capacity, approximately 5 cfs) 

diverts water from tributary spring about 1,000 ft above station (diversions began 

Aug. 1, 1941). At times, a part of this flow is returned to Ashley Creek half a mile 

below station.

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. 30 years (1925-26, 1929-58), 172 cfs (124,500 acre-ft per year).

Extremes. Maximum discharge during year, 1,940 cfs May 28 (gage height, 4.97 ft); minimum 

recorded, 34 cfs Apr. 1, but may have been less during periods of no gage-height record. 

1929-58: 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. Flow 

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.

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

Average discharge.--43 years (1909-20, 1921-27, 1932-58), 104 cfs (75,290 acre-ft per 

year) .

Extremes. Maximum discharge during year, 1,260 cfs June 5 (gage height, 4.35 ft); maximum gage height, 4.57 ft Aug. 22; minimum discharge, 17 cfs Apr. 6.

1909-27, 1932-58: Maximum discharge, 2,870 cfs Aug. 9, 1941 (gage height, 6.38 ft, 

site and datum then in use), from rating curve extended above 780 cfs; minimum 

observed, 4 cfs Jan. 24, 1933 (discharge measurement).

Remarks.--Records good except those for periods of ice effect and fragmentary or no gageheight record, which are fair. Small diversions above station for irrigation. Ephraim 

and Spring City tunnels constructed by Bureau of Reclamation in 1936 and 1938, respectively, and several small canals divert from headwaters of Cottonwood Creek to The 

Great Basin for irrigation in San Pitch River basin (see p. 330).

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

1909.

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

which are poor. Discharge measurements generally made twice a month. Plow regulated 

by Vallecito Reservoir since April 1941 (see p. 301). Diversions for irrigation of 

about 25,000 acres above station.

and 1 mile west of Parmington.

Drainage area. 7.240 sq mi, approximately.

Records available. June to December 1904, January 1905 to September 1906 (gage heights 

and discharge measurements only; discharge records for January to December 1905 published in WSP 175 have been found to be unreliable and should not be used), September 

1912 to September 1958. Monthly discharge only for some periods, published in 

WSP 1313.

g_. Water-stage recorder. Datum of gage is 5,230.37 ft above mean sea level, datum of 

~29. June 19, 1904, to May 10, 1906, wire-weight gage at site L| miles downstream at 

different datum. May 11 to Sept. 22, 1906, chain gage and Sept. 19, 1912, to July 2, 

1918, staff gage, at site half a mile upstream at different daturas. Nov. 1, 1921, to 

Nov. 18, 1933, water-stage recorder at site 360 ft upstream at datum 1.04 ft higher 

prior to 1932, and 0.53 ft higher thereafter.

Average discharge. 46 years (1912-58), 2,637 cfs (1,909,000 acre-ft per year).

Extremes. Maximum discharge during year, 17,100 cfs June 7 (gage height, 6.18 ft); minimum daily, 348 cfs Sept. 5.

1912-58: Maximum discharge, about 68,000 cfs June 29, 1927 (gage height, 10.2 ft, 

site and datum then in use), from rating curve extended above 37,000 cfs; minimum 

daily, 27 cfs Aug. 22, 1939.

Maximum flood known occurred Oct. 6, 1911. Flood of Sept. 6, 1909, reached a stage 

of about 12.3 ft, site and datum then in use.

Remarks. Records good April to September, others fair except those for periods of ice 

effect or doubtful gage-height record, which are poor. Discharge measurements generally made 3 or 4 times a month. Diversions above station for irrigation of about 

86,000 acres, 4,000 of which are below station.

1929. Prior to May 1, 1920, staff gage and May 1, 1920, to May 24, 1927, water-stage 

recorder at several sites about 600 ft downstream at different daturas. May 25, 1927, 

to Sept. 30, 1938, water-stage recorder at site 60 ft downstream and Oct. 1, 1938, to 

Sept. 30, 1941, at present site at datum 1.00 ft higher.

Average discharge. 42 years (1905-6, 1917-58), 47.1 cfs (34,100 acre-ft per year).

Extremes. Maximum discharge during year, 652 cfs May 27 (gage height, 3.49 ft); minimum 

daily, 9 cfs Jan. 22, 23, Feb. 26 to Mar. 3.

1904-6, 1910, 1917-58: Maximum discharge, 1,880 cfs Sept. 22, 1941 (gage height, 

4.30 ft, present datum), from rating curve extended above 620 cfs on basis of slopearea measurement of peak flow; minimum not determined. 

Maximum flood known occurred Oct. 5, 1911.

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

which are poor. One diversion above station for irrigation of about 2,000 acres along 

Cherry Creek below station.

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 1958. 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 

1929. Prior to Jan. 19, 1923, staff gages or reference points within 400 ft of present 

gage, at different datums.

Average discharge. 47 years (1911-58), 18,270 cfs (13,230,000 acre-ft per year).

Extremes. Maximum discharge during year, 106,000 cfs June 1 (gage height, 19.00 ft); mlnimum, 3,400 cfs Aug. 21 (gage height, 6.17 ft).

1921-58: Maximum discharge, 220,000 cfs June 18, 1921 (gage height, 26.5 ft, from 

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

4.2 ft).

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

above 120,000 cfs on basis of discharge computed for flood of June 18, 1921, for 

station near Grand Canyon.

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

Natural flow of stream affected by transmountaln 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. Records of 

chemical analyses, suspended sediment loads, and water temperatures for the water year 

1958 are given In WSP 1574.

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

1.70 ft higher. Aug. 2 to Oct. 27, 1940, staff gage at site within 1 mile upstream at 

different datum.

Average discharge.--18 years, 19.7 cfs (14,260 acre-ft per year); median of yearly mean 

discharges, 14 cfs (10,100 acre-ft per year).

Extremes. -Maximum discharge during year, 1,120 cfs Apr. 23 (gage height, 11.28 ft); minimum, 1.0 cfs Oct. 21.

1940-58: Maximum discharge, 16,000 cfs July 25, 1940 (gage height, 17.1 ft, present 

datum, from floodmarks), by slope-area measurement of peak flow and reservoir inflow 

studies; no flow many days 1950-57.

Remarks. Records fair except those for periods of ice effect- or doubtful gage-height 

record, which are poor. Flow regulated by many small reservoirs, combined capacity, 

about 15,500 acre-ft. Diversions for irrigation of about 6,700 acres above station.

 stream from outlet tunnel in Lyman Dam and 9 1/3 miles south of St. Johns.

Drainage area. 790 sq mi.

Records available.--April 1941 to June 1954, April 1955 to September 1958.

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

released to river channel. Datum of gage is 5,925.35 ft above mean sea level, datum 

of 1929. Water-stage recorder on Lyman Reservoir for determination of flow in spillway channel three-eighths of a mile north in SWir sec. 4. T. 11 N., R. 28 E.

Average discharge. 15 years (1941-53; 1956-58), 2.64 cfs (1,910 acre-ft per year).

Extremes. Maximum daily discharge during year, 11 cfs May 7-18; minimum daily, 0.2 cfs 

on Mar. 20.

1941-58: Maximum discharge observed, 603 cfs May 8, 1941 (including 546 cfs of 

spilled water); no flow at times most years.

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

 which are poor. Record of daily discharge shows all water spilled and released from 

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

Canal (see p. 335 ). See monthly table for combined flow of river and canal. Ho flow 

over Lyman Dam spillway this year. Since 1929 spill has occurred only during period 

Apr. 8 to about May 6, 1932, and Apr. 30 to May 13, 1941. Plow completely regulated 

by many reservoirs (combined capacity, 46,900 acre-ft, the largest of which is Lyman 

Reservoir (capacity, 31,390 acre-ft). Diversions above station for irrigation of 

about 8,200 acres, including 1,500 acres served by Lyman Canal. Plow past this 

station supplemented by spring inflow downstream used to irrigate an additional 

2,000 acres in vicinity of St. Johns.

discharge only), October 1955 to September 1958. 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 

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

at different datum.

Extremes. Maximum daily discharge during year, 7.9 cfs July 13, 14; minimum daily, 

0.03 cfs Mar. 6-22.

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.

1953-58: Maximum daily discharge, 7.9 cfs Sept. 6-8, 1955, July 13, 14, 1958; no 

flow at times 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 Isee 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., 4j miles southeast of Show Low; dam 

completed and storage began in spring of 1953. Total capacity, 6,176 acre-ft, consisting 6T 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 Apr. 2 to Aug. 20. Elevations obtained daily during pumping and weekly the 

remainder of the year by Navapache Electric Co-operative, Inc. and monthly by Geological Survey.

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 1958.

Average discharge. 10 years (1905-6, 1949-58), 99.0 cfs (71,670 acre-ft per year).

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

of 1929. March 1905 to December 1909, staff gage at former highway bridge Just 

upstream from present bridge at different datum.

Extremes. Maximum discharge during year, 7,000 cfs Sept. 14 (gage height, 8.85 ft); min 

imum daily, 0.3 cfs Aug. 2.

1905-9, 1949-58: 'Maximum discharge determined, 21,800 cfs Aug. 5, 1957 (gage 

height, 10.96 ft); maximum daily, 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 353

4025. 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 1958. Prior to 1944, published as Colorado 

River at Bright Angel Creek, near Grand Canyon. Gage-height records collected if- 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. 36 years, 17,320 cfs (12,540,000 acre-ft per year).

Extremes.--Maximum discharge during year, 108,000 cfs June 2 (gage height, 26.97 ft); minimum, 4,080 cfs Aug. 21.

1922-58: 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 except those for periods of fragmentary gage-height record, 

which are good. 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, suspended sediment loads and water temperatures for the water year 1958 are given in WSP 1574.

354 BRIGHT ANGEL CREEK BASIN

4030. Bright Angel Creek near Grand Canyon, Ariz.

Location. Lat 36 C 05'55", long 112°Q5<4Q tt , on right bank 1,000 ft upstream from mouth and 

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

Drainage area. 98.4 sq mi.

Records available. October 1923 to September 1958.

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

Is 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 datums. Jan. 30, 1933, to Aug. 19, 1936, waterstage recorder 200 ft upstream from present site at datum 4.5 ft higher.

Average discharge. 35 years, 37.4 cfs (27,080 acre-ft per year).

Extremes. Maximum discharge during year, about 900 cfs Aug. 22 (gage height, 2.33 ft); 

minimum daily, 17 cfs for several days.

1923-58: Maximum discharge, 4,400 cfs Aug. 19, 1936, from rating curve extended 

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

Aug. 6-9, 1954.

Remarks. Records good below 50 cfs and fair above except those for periods of doubtful 

or no gage-height record, or indefinite stage-discharge relation, which are poor. 

Minor diversion for irrigation of a few acres above station. Discharge measurements 

made 3 times a month. Some fluctuation in flow caused by powerplant 9 miles upstream 

from station; no regulation by storage.

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

364 VIRGIN RIVER BASIN

4160. Muddy River near Moapa, Nev.

Location. Lat 36°43', long 114°42', in SE£ sec. 15, T. 14 S., R. 65 E., on left bank 

three-quarters of a mile downstream from Home Ranch, 5 miles northwest of Moapa, and 

9? miles upstream from Meadow Valley Wash.

Drainage area. 3.860 sq mi, approximately, of which about 80 sq mi contributes directly 

to surface runoff.

Records available. July 1913 to September 1915, April 1916 to September 1918, June 1928 

to October 1931, April to July 1932, October 1944 to September 1958. Monthly discharge only for some periods, published in WSP 1313. Records for January 1904 to 

December 1906 (gage heights only), 1908-9 (discharge measurements only), and April 

to October 1910 not equivalent owing to large difference in drainage area.

Sage. Water-stage recorder and Cippoletti weir. Altitude of gage is 1,710 ft (from 

river-profile map). Oct. 21, 1944, to Sept. 30, 1948, water-stage recorder at datum 

0.08 ft higher.

Average discharge. SI years (1913-15, 1916-18, 1928-31, 1944-58), 46.5 cfs (33,660 

acre-ft per year).

Extremes. Maximum discharge during year, 280 cfs Feb. 4 (gage height, 3.23 ft); minimum, 

37 cfs May 22.

1913, 1915-17, 1945-58: Maximum discharge uncertain, occurred Feb. 21, 1914 (gage 

height, 9.9 ft); minimum, 34 cfs Nov. 20, 1951.

Remarks. Records excellent. Diversions for irrigation above station. Normal flow 

originates from springs in reach 0.9 to 2.5 miles upstream from station.

Revisions (water years). WSP 1243: 1914(M). WSP 1343: 1950(M).

Records available. January 1917 to September 1958, 

since October 1938.

Daily mean elevations published

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

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

Dec. 3, 1922, at site about 1 mile upstream at different datum. Since May 1, 1939, 

auxiliary water-stage recorder at former highway bridge at Topock, 2.7 miles upstream 

from base gage at datum 13.33 ft higher.

Average discharge.--17 years (1917-34), 20,260 cfs (14,670,000 acre-ft per year); 24 years 

(1934-58) , 14,190 cfs (10,870,000 acre-ft per year), unadjusted.

Extremes. Maximum daily discharge during year, 24,500 cfs May 3; maximum elevation,

457.05 ft May 11; minimum daily discharge, 8,080 cfs Oct. 28; minimum elevation, 45233 

ft Oct. 28.

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

1,480 cfs Aug. 17, 1934.

1934-58; Maximum discharge, 35,700 cfs Jan. 29, 1942; maximum elevation, that of 

May 11, 1958; minimum discharge, 375 cfs Feb. 14.

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

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

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

DIVERSIONS FROM HAVASU LAKE 377

4270. Colorado River aqueduct near Parker Dam, Ariz.-Calif.

Location. Lat 34°19'00", 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 1958 (monthly discharge only after October 

1942, published 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. 19 years, 287 cfs (207,800 acre-ft per year).

Extremes. Maximum daily diversion during year, 1,130 cfs Dec. 14; no flow Dec. 6, 10-12, 

Jan.21.

1939-58: Maximum daily diversion, that of Dec. 14, 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 4,581 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.

Location. Lat 34°19'00", long 114°09'25", in NW-J-SW^ sec. 28, T. 3 N., R. 27 E., San

Bernardino meridian, at intake pumping plant for Colorado River aqueduct of Metropolitan Water District of Southern California, 1.8 miles upstream from Parker Dam on Colorato River, which is 156 miles downstream from Hoover Dam.

Drainage area. 178.800 sq mi, approximately, at Parker Dam.

Records available. July 1938 to September 1958. Published as "Parker Reservoir near 

Parker Dam" 1938.

Gage. Water-stage recorder. Datum of gage is 400.54 ft above mean sea level, datura of 

T929. Gage readings have been reduced to elevations above mean sea level.

Extremes. Maximum contents during year, 624,000 acre-ft June 26 (elevation, 450.77 ft); 

minimum, 510,400 acre-ft Jan. 16 (elevation, 444.74 ft).

1938-58: Maximum contents, 693,000 acre-ft (by temporary use of flashboards) 

Apr. 18, 1943, June 4, 1953; maximum elevation, that of June 26, 1958; minimum contents, 

71,400 acre-ft June 25, 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 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. Prior to Oct. 1, 1956, different capacity table used. 

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) 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, reregulation 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. Figures 

given herein represent usable contents. For record of diversion to Colorado River 

aqueduct and return flows, see record for Colorado River aqueduct near Parker Dam (see 

p. 377).

Location. Lat 34°15'30", long 114°09'00", in NE^SWi 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 1958. Published as "near Parker, Ariz.," prior 

to October 1937.

Gage. Water-stage recorder. 

1929.

Datum of gage is 346.23 ft above mean sea level, datum of

Average discharge. 24 years (1934-58), 13,890 cfs (10,060,000 acre-ft per year), unadjusted; 13,930 cfs (10,080,000 acre-ft per year), adjusted to include storage in 

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

Extremes. Maximum discharge during year, 22,800 cfs Apr. 22 (gage height, 22.53 ft); 

minimum, 3,690 cfs Oct. 17 (gage height, 17.59 ft).

1934-58: 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

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

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

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

at Yuma, All-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.--24 years (1934-58) 13,060 cfs (9,455,000 acre-ft per year).

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 1958 (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. Records of daily discharge since 1936 published 

in reports of Gila Water Commissioner.

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.

4460. Willow Creek near Double Circle Ranch, near Morenci, Ariz.

Location. Lat 33°21'15", long 109°31'30", in NE^ see. 13, T. 1 S., R. 27 E., unsurveyea, in San Carlos Indian Reservation, on left bank 1 mile upstream from lower end 

of box canyon, 2^ miles northwest of Double Circle Ranch, 2f miles upstream from 

mouth, and 19 miles northwest of Morenci.

Drainage area. 149 sq mi.

Records available.--August 1944 to September 1958.

Gage. Water-stage recorder. Altitude of gage is 4,969 ft (by barometer).

Average dlschar^ 

of unadjustec

e. 14 years,'12.7 cfs (9,190 acre-ft per year), unadjusted; median of 

"yearly mean discharges, 11 cfs (8,000 acre-ft per year).

Extremes. Maximum discharge during year, 1,640 cfs Mar. 22 (gage height, 6.84 ft), from 

rating curve extended above 200 cfs as explained below; minimum, 0.2 cfs Jan. 24, 

result of freezeup upstream.

1944-58: Maximum discharge, 4,230 cfs Jan. 13, 1952 (gage height, 7.62 ft), from 

rating curve extended above 20 cfs on basis of slope-area measurement of peak flow; 

maximum gage height, 7.72 ft Aug. 6, 1955; no flow Sept. 1-10, 1944, and part of 

June 29, 1946.

Remarks. Records good except those above 100 cfs, which are fair, and those for periods 

of no gage-height record, which are poor. Most flow of less than 20 cfs past this 

station is water pumped from Black River (see p. 394).

4470. Eagle Creek above pumping plant, near Morenci, Ariz.

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 1958.

Sage. Water-stage recorder, Parshall flume and weir. Altitude of gages is 3,650 ft 

Tfrom 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. 14 years, 32.8 cfs (23,750 acre-ft per year), unadjusted; median of 

yearly mean discharges, 26 cfs (18,800 acre-ft per year).

Extremes. Maximum discharge during year, 6,150 cfs Sept. 10 (gage height, 8.1 ft, at 

supplementary gage); minimum, 7.3 cfs July 14.

1944-58: Maximum discharge, that of Sept. 10, 1958; minimum, 3.2 cfs July 1, 1946.

A discharge of 13,000 cfs (by slope-area measurement of peak flow) occurred Feb. 10, 

1932, at a stage of 11 ft above normal low water at footbridge 2? miles downstream.

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

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

from Black River was pumped into Eagle Creek basin, 514 miles upstream from this 

station, for about three-quarters of the year (see p. %94). Diversions by pumping 

for industrial and municipal 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-three 

percent of the pumpage was from Eagle Creek.

4490. Diversions from Gila River in Safford Valley, Ariz.

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

vicinity of Bonita Creek on the east to San Carlos Indian Reservation on the west. 

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

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

end of the valley, is 0.6 mile upstream from station on Gila River near Solomon. 

Intake of Colvin-Jones Canal, at the lower end, is 25.8 miles upstream from station at 

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

Records available. 1936-58 (records of combined monthly diversions in Safford Valley, 

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

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

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

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

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

Remarks. Record shows total diversions unadjusted for return flows. Decreed area for 

irrigation in Safford Valley is 32,512 acres. Water was issued this year for entire 

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

not included.

Cooperation. Records furnished by Gila Water Commissioner.

GILA RIVER BASIN 

4695. Gila River below Coolidge Dam, Ariz.

411

Location.--Lat 33°10'15", long 110°31'45", in SW£ sec. 17, T. 3 S., R. 18 E., unsurveyed, 

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

Drainage area. 12 .886 sq mi.

Records available. July to October 1899, April 1900 to March 1902, July to September 1902, 

December 1908 to December 1904; January to May 1905 (gage heights only); June to November 1905; August 1910 to February 1911 (gage heights only); April 1914 to September 

1958. Published as "at San Carlos" 1899-1911, as "near San Carlos" 1914-26, as "at 

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) . 46 years (1900-1901, 

19U3-4, 1914-58), 366 cfs (265,000 acre-ft per year); median of yearly mean discharges, 

230 cfs (167,000 acre-ft per year).

Extremes. Maximum discharge during year, 924 cfs July 12 (head on flume, 3.66 ft); minimum daily, 2.8 cfs for several days in October and November.

1914-58: 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 for period of no gage-height record, which are 

poor. 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 1958 

water year as 0.53 cfs on Jan. 10, 0.57 cfs on May 21, and 0.65 cfs on June 11.

Records available. June 1943 to June 1947, July 1950 to September 1958 (monthly discharge 

only, July 1954 to March 1955). Also extremes for water years 1948-50, published in 

WSF 1179.

Gage. Water-stage recorder and supplemental water-stage recorder 460 ft downstream. Datum 

of gage is 2,940.51 ft above mean sea level, datum of 1929. Prior to July 1950, at 

site 400 ft downstream at datum 2.98 ft lower.

Average discharge. 11 years (1943-46, 1950-58), 56.8 cfs (41,120 acre-ft per year); medlan or yearly mean discharges, 37 cfs (26,800 acre-ft per year).

Extremes. Maximum discharge during year, 10,800 cfs Aug. 17 (gage height, 10.03 ft); no 

flow for many days.

1943-58: Maximum discharge, 28,600 cfs Aug. 2, 1951 (gage height, 18.0 ft), from 

rating curve extended above 1,400 cfs on basis of slope-area measurement of peak flow; 

no flow at times in each year.

Maximum discharge known, about 90,000 cfs Sept. 28, 1926 (gage height, 21.5 ft, 

former datum, from floodmark), computed on basis of peak discharge of same flood for 

station at Charleston and for Oila River at Kelvin.

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

which are poor. Diversions above station for irrigation of about 5,300 acres, including about 200 acres in Mexico.

416 MLA RIVER BASIN

4740. alia River at Kelvin, Ariz.

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

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

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

Drainage area. 18.011 sq mi, of which 5,125 sq mi is below Coolidge Dam. 

Records available. January 1911 to September 1958.

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

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

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

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

Average discharge. 47 years (1911-58), 494 cfs (357,600 acre-ft per year); median of 

yearly mean discharges, 350 cfs (253,000 acre-ft per year); adjusted for storage in 

San Carlos Reservoir.

Extremes. Maximum discharge during year, 5,310 cfs Aug. 6 (gage height, 8.40 ft); minimum daily discharge, 11 cfs Oct. 26-28.

1911-58; Maximum discharge, about 132,000 cfs Jan. 20, 1916 (gage height, 19.5.ft), 

from rating curve extended above slope-area measurement at gage height 16.2 ft; minimum, less than 1 cfs in summers of several years.

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

height, 12.6 ft).

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

Discharge measurements generally made 3 times a month during release from Cooldige 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. 410); no other regulation. San Pedro River contributes major portion on unregulated inflow. Records of 

chemical analyses, suspended sediment loads, and water temperatures for the water 

year 1958 are given in WSP 1574.

GILA RIVER BASIN 417

4750. Glla River at Ashurst-Hayden Dam, near Florence, Arlz.

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

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

Drainage area. 18.305 sq ml.

Records available. July 1923 to September 1958 (head on crest of dam only). Records of 

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

1958.

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

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

record of diversion. Prior to Jan. 12, 1937, water-stage recorder 900 ft downstream 

from Ashurst-Hayden Dam.

Extremes. Maximum head on dam during year, 1.45 ft Oct. 12; no flow over dam greater 

part of year.

1923-58; Maximum head on dam, 8.0 ft Sept. 28, 1926; no flow over dam greater 

part of each year.

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

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

extensive sluicing. Florence-Casa Grande Canal diverts water at dam supplemented by 

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

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

to show water available at dam, except for flow through dam or water 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.

GILA RIVER BASIN 425

4830. Tucson Arroyo at Vine Avenue, Tucson, Ariz.

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

right bank at Vine Avenue, a quarter of a mile downstream from Arroyo Chico and 

2j 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 1958.

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

mean sea level (city of Tucson bench mark).

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

from 23.4 sq mi.

Extremes.--Maximum discharge during year, 860 cfs Sept. 11 (gage height, 6.40 ft); no 

flow most of year.

1944-58: 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 measurement of 

peak flow; no flow most of each year.

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

A flood-control project diverted runoff from 15.2 sq mi at upper end of basin into a 

flood-control detention reservoir in SEij- 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. An overflow spillway on main interceptor canal in NE£sw£ sec. 22, 

T. 14 S., R. 14 E., allows overflow to Tucson Arroyo when canal discharge exceeds 

about 1,000 cfs.

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

different datum.

Average discharge. 15 years (1939-46, 1950-58), 28.5 cfs (20,630 acre-ft per year); 

median of yearly mean discharges, 23 cfs (16,700 acre-ft per year).

Extremes. Maximum discharge during year, 7,890 cfs Aug. 12 (gage height, 7.03 ft); no 

flow for many days.

1939-47, 1950-58: Maximum discharge, 17,000 cfs Aug. 14, 1940 (gage height, 9.9 ft, 

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

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

which are poor. 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.

929, Phoenix-Picacho supplementary adjustment of 1949.

Average discharge. 16 years (1940-46, 1948-58), 22.6 cfs (16,360 acre-ft per year); 

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

Extremes. Maximum discharge during year, 3,360 cfs Nov. 3 (gage height, 16.10 ft); no 

flow many days.

1940-46, 1947-58: 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 many years.

Remarks. Records good except those for periods of doubtful or 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.

GILA RIVER BASIN 

5010. Reservoir System on Salt River at and below Roosevelt Dam, Ariz.

453

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

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

Canyon Lake, formed by Mormon 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 1958. Prior to October 1934, month-end contents only, published in WSP 1313.

Evaporation: April to September 1958.

Gages. Roosevelt Lake, water-stage recorder. Apache Lake, water-stage indicator in 

powerplant connected to long distance transmitter on lake since April 1949; prior to 

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

gages.

Extremes. Maximum contents of system during year, 905,200 acre-ft May 29; minimum contents, 293,200 acre-ft Oct. 4.

1910-58: 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 Lake, 70,000 acre-ft. Dams forming these reservoirs were built as follows: 

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

The 4 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, and Apr. 13 to July 24, 1941. Water from this system is used for irrigation of 

Salt River Valley and for generation of power.

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

Association.

Revisions. WSP 1283: Drainage area.

Usable contents, in thousands of acre-feet, at 12 p.m., water year October 1957 to September 1958

5075. Fossil Creek diversions to Childs powerplant, near Camp Verde, Ariz.

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

head of Stehr Lake, 2^ 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 1958.

§_. Water-stage recorder and weir in concrete flume, 

from topographic map).

Altitude of gage is 3,730 ft

Extremes. Maximum daily discharge during year, 46 cfs Jan. 13, Feb. 3, 17-19, Mar. 7, 

Sept. 12, 23, 24, 26; minimum, 23 cfs Nov. 5.

1952-58: Maximum daily discharge, 51 cfs Apr. 17-21, 1952; no flow for brief 

periods in most years.

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

and shows the water used by 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: 

Oct. 16, 0.89 cfs; Nov. 21, 1.59 cfs; Dec. 18, 1.28 cfs; Jan. 17, 1.06 cfs; June 13, 

1.05 cfs; July 18, 0.65 cfs; and Sept. 25, 2.31 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 97 percent of record published 

herewith.

Location. Lat 34°04'25", long 111°42 I 50", in sec. 35, T. 9 N., R. 6 E., unsurveyed, in 

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

upstream from Horseshoe Dam.

Drainage area. 5.872 sq mi (including 373 sq mi in Aubrey Valley Playa, a closed basin). 

Records available. August 1945 to September 1958.

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

929.

Average discharge. 13 years, 411 cfs (297,600 acre-ft per year); median of yearly mean 

discharges, 330 cfs (239,000 acre-ft per year).

Extremes. Maximum discharge during year, 21,100 cfs Mar. 23 (gage height, 14.30 ft); minimum, 48 cfs July 18, 19, caused by power regulation on Fossil Creek.

1945-58: Maximum discharge, 81,600 cfs Dec. 31, 1951 (gage height, 17.62 ft), from 

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

48 cfs June 17, 1956, July 18, 19, 1958, caused by power regulation on Fossil Creek.

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

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.

"at McDowell," "at McDowell near Lehi," "near McDowell," and "above Camp Creek near 

McDowell."

Gage.. Water-stage recorder. Datum of gage is 1,572.34 ft above mean sea level, datum 

of 1929. Prior to Feb. 17, 1925, staff gages at several sites about 20 miles downstream at various datums. Feb. 17, 1925, to Dec. 31, 1941, water-stage recorder at 

two sites within half a mile upstream from Camp Creek, at various datums.

Average discharge. 70 years, 692 cfs (501,000 acre-ft per year), adjusted for storage 

in Bartlett and Horseshoe Reservoirs.

Extremes. Maximum discharge during year, 4,150 cfs Mar. 25 (gage height, 8.07 ft); minimum daily, 6 cfs Jan. 28 to Feb. 1.

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

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

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

1939-58: Maximum discharge, 45,800 cfs Mar. 15, 1941 (gage height, 17.5 ft, present site and datum, from floodmarks); no flow at Bartlett Dam at times in several 

years when gates in dam were closed.

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

which are fair. Discharge measurements generally made four times a month. Diversions 

for irrigation above station of about 12,500 acres, some of which is by pumping from 

ground water. Flow completely regulated by Bartlett Reservoir since Feb. 5, 1939, 

and by Horseshoe Reservoir since Nov. 15, 1945 (see preceding page), except during 

periods of spill or occasional flood flows below Bartlett Dam. Records of chemical 

analyses and water temperatures for the water year 1958 are given in WSP 1574.

Revisions (water years). WSP 1049: 1893, 1913-14, 1917-18, 1925-27 1929. WSP 1213-

discharges, 9.4 cfs (6,800 acre-ft per year).

Extremes. Maximum discharge during year, 4,620 cfs June 21 (gage height, 7.72 ft); minimum daily, 0.2 cfs June 10-16.

1940-58: Maximum discharge, 13,000 cfs Mar. 1, 1941, from rating curve extended 

above 1,600 cfs on basis of slope-area measurement of peak flow; maximum gage height, 

12.00 ft Aug. 3, 1955; negligible flow at times during the summer months in most years 

when entire flow was diverted to Perry Canal above station and flow past gage was 

seepage only.

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

Diversions above station for mining and irrigation of about 600 acres. Water diverted 

just upstream from station to Perry Canal.

5130. Agua Fria River at Lake Pleasant Dam, Ariz.

Location . Lat 33°51', long 112°16', in NW£ sec. 21, T. 6 N., R. IE., 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 heights only), October 1933 to 

September 1958 (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 Lj miles downstream from 

Lake Pleasant Dam, at different datum.

Average discharge. 30 years (1914-19, 1933-58), 93.3 cfs (67,550 acre -ft per year); 

median of yearly mean discharges, 47 cfs (34,000 acre-ft per year).

Extremes . 1910-24 . 1933-58: 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) computed 

from twice-daily readings by Clausen-Peirce weir rule and release by hydrograph. Weir 

rule readings checked by current meter measurements by U. S. Geological Survey; (b) 

spill from Lake Pleasant as measured over diversion dam (none since 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 1-g- ft in ground near left end of 

Lake Pleasant Dam. Effect of bank storage and bank release in Lake Pleasant is not 

taken into account. For months when inflow to lake is small and other factors relatively large, discordant figures of runoff may appear. Such discrepancies that may be 

attributed to inaccuracies in the capacity table or to the fact that bank storage and 

bank release are not taken into account, result in quantities too large for periods of 

falling stage but are compensated for by quantities too small for periods of rising 

stage. Inaccuracies in figures of release and evaporation, which may be within reasonable limits within themselves, may result in disproportionally large inaccuracies in 

small figures of inflow computed as residuals. Diversions for irrigation above Lake 

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

temperatures for the water year 1958 are given in WSP 1574.

Cooperation. Records collected and prepared in cooperation with Maricopa County Municipal

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

end of Lake Pleasant Dam on Agua Fria River.

Drainage area. 1,460 sq mi, approximately.

Records available. February 1928 to September 1958 (yearly data only, prior to 1939).

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

~<Iatum of 1929.

Extremes. Maximum contents during year, 24,400 acre-ft Apr. 22 (gage height, 105.80 ft);

 minimum, 3,160 acre-ft Oct. 2, 3, 10, 11.

1928-58: 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.

5140. 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 1958.

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.

Average discharge. 5 years, 31.4 cfs (22,800 acre-ft per year).

Extremes. Maximum daily discharge during year, 245 cfs Aug. 9; no flow Oct. 3-6.

I§53-58: Maximum daily discharge, 257 cfs Aug. 8, 1954; no flow for several days 

In most years.

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

Canal diverts from right bank of Gila River in SE£SW£ sec. 28, T. 1 N., R. 1 W., for 

Irrigation in the Buckeye area. Total 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 

SWpW^ 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 (see table below) furnished by Salt River 

Valley Water Users' Association.

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

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

Drainage area. 49,620 sq mi.

Records available. August 1921 to September 1958 (river below dam only). Records for 

Gila Bend Canal May 1935 to September 1958 (since October 1941, monthly discharge 

only); for Enterprise Canal June 1935 to September 1939 (discharge measurements and 

monthly estimates only), October 1939 to September 1958 (since October 1941, monthly 

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

June 1935 to September 1958. Published as "at Gillespie Dam" prior to 1939. 

s.~Gila River: Water-stage recorder since July 28, 1924. Datum of gage is 10.00 ft 

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

datum of 1929. Prior to Nov. 11, 1924, depth of water read on crest at left end of 

dam. Nov. 11, 1924, to July 22, 1932, datum of gage was at average elevation of dam 

crest. July 23, 1932, to Apr. 27, 1955, datum of gage was 5.00 ft below average 

elevation of 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). 17 years (1941-58), 28.3 cfs (20,490 acre-ft per 

year); median or yearly mean discharges, 14 cfs (10,100 acre-ft per year).

Extremes. Maximum discharge over dam during year, 976 cfs Sept. 13 (gage height, 

10.48 ft); no flow most of year.

1921-58: 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 fair. Records include flow over crest and through sluice gates of

Gillespie Dam, but do not include flow in Gila Bend and Enterprise Canals which divert 

from river immediately above dam. Other large diversions above station for irrigation. 

Plow 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 Pria River 

(capacity, 163,800 acre-ft). Leakage through closed sluice gates is estimated as 

about 0.5 cfs during periods of no flow and is not included in the record.

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 following page. 

Records of combined flow are fair. Records of suspended sediment loads and water 

temperatures for the water year 1958 are given in WSP 1574.

GILA RIVER BASIN 469

5205. Gila River near Dome, Ariz.

Location Lat 32°45'40", long 114°25'10", in SWi sec. 4, T. 8 S., R. 21 W. , on right bank 

440 ft upstream from bridge on State Highway 95, 3 miles west of Dome, and 12 miles 

upstream from mouth.

Drainage area.--58,080 sq mi, approximately (includes 373 sq mi in Aubrey Valley Playa, a 

closed basin, and excludes all other closed basins).

Records available. January 1903 to September 1958. Monthly discharge only for some 

periods, published in WSP 1313. Published as "at Yuma and Gila City" 1903, as "near 

Gila City11 1904, and as "at Dome (Gila City)" 1905-6. Records for 1907-29 are 

published in WSP 918 as "at Yuma and at and near Dome."

Gage. Water-stage recorder since May 1929. Datum of gage is 148.18 ft above mean sea 

level, datum of 1929. Prior to October 1903 and January 1907 to April 1929, no gage; 

discharge estimated. October 1903 to December 1906, principal staff gage 4 miles 

upstream at datum 158.37 ft above mean sea level, adjustment of 1912, supplemented by 

many staff gages at different datums.

Extremes. Maximum discharge during year, 719 cfs July 31 (gage height, 8.63 ft); no flow 

most of year.

1929-58: Maximum discharge, 20,700 cfs Feb. 15, 1932 (gage height, 16.75 ft); no 

flow part or all of each year.

Maximum daily discharge, 200,000 cfs (roughly estimated) Jan. 22, 1916.

Remarks.--Records good. Most low flow is waste and drainage return from Wellton-Mohawk 

Division of Gila project. Many diversions above station for irrigation. Flow above 

station regulated by reservoirs at and above Gillespie Dam (see Remarks for that 

station).

Revisions (water years). WSP 918: 1905. WSP 1283: Drainage area.

5230. All-American Oanal near Imperial Dam, Ariz. -Calif .

Location. Lat 32«52'15", long 114«28'50" in SEjNW^ sec. 17, T. 15 S., R. 24 E., San 

Bernardino meridian, on left bank 6,000 ft downstream from intake at west end of 

Imperial Dam and 13£ miles upstream from turnout to Yuma Main Canal .

Records available . October 1938 to September 1958. 

October 1939, published in WSP 1313.

Monthly discharge only prior to

gage. Water-stage recorder. Datum of gage is 150.00 ft above mean sea level, datum of 

1929 (subject to undetermined changes caused by earthquake of May 18, 1940). 

Since Aug. 21, 1952, auxiliary water-stage recorder 18| miles downstream from base gage.

Average discharge.--17 years (1941-58), 7,131 cfs (5,163,000 acre-ft per year).

Extremes. Maximum daily discharge during year, 13,500 cfs Apr. 16; maximum gage height, 

24.51 ft Apr. 16; minimum daily discharge, 3,580 cfs Feb. 9.

1938-58: Maximum daily discharge, that of Apr. 16, 1958; maximum gage height, that 

of Apr. 16, 1958; no flow at times in several years.

Remarks. Records excellent. Discharge measurements generally made every 4 to 5 days. 

All-American Canal diverts water from Colorado River at Imperial Dam. Water is used 

for power development and for irrigation in Yuma, Coachella, and Imperial Valleys. 

Water can be released back to the river through Pilot Knob powerplant and wasteway for 

power, regulatory purposes, or for downstream use in Mexico. First diversion to AllAmerican Canal began October 1938 but prior to October 1940 was used only for priming 

canal.

Cooperation. gage-height record furnished by Imperial Irrigation District.

Discharge, In cubic feet per second, water year October 1957 to September 1958

DIVERSIONS AND RETURN FLOWS AT AND BELOW IMPERIAL DAM

5240. Yuma Main Canal at siphon-drop powerplant, near Yuma, Ariz.

Location. Lat 32°46'35", long 114 0 38'05", in SE-fSE^ 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 14jr miles downstream from intake of Ail-American Canal at Imperial Dam.

Records available.--July 1926 to September 1958. Monthly discharge only prior to October 

1938, published in WSP 1313. Diversions from All-American Canal and Yuma Main Canal 

above siphon-drop powerplant, October 1947 to September 1958 (monthly discharge only). 

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

wasteway, October 1940 to September 1958 (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. 32 years, 1,707 cfs (1,236,000 acre-ft per year).

Extremes. Maximum daily discharge during year, 2,020 cfs Feb. 15, Aug. 1, 2; minimum 

daily, 571 cfs Oct. 7.

1930-58: Maximum daily discharge, 2,040 cfs Nov. 11, 1943; no flow for some days in 

1937-39, 1945.

Remarks. Records excellent. 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 All-American Canal to Yuma Main Canal. Records show quantity of water 

diverted from All-American Canal to Yuma Main Canal, except that diverted from forebay 

of powerplant to Walapai Canal. The water not needed for irrigation on Yuma project is 

returned to Colorado River through Yuma Main Canal wasteway, 3 f miles downstream. 

The combined diversions by several small canals from the All-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 to 

irrigate about 9,100 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 Reclamation.

Discharge, in cubic feet per second, water year October 1957 to September 195S

5250. 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 SWJj-SEi sec. 26, T. 16 S., R. 22 E., San Bernardino 

meridian, 1,645 ft upstream from intake of Colorado River siphon on Yuma Main Canal, 

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

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

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

Records available. April 1913 to September 1958. Monthly discharge only for some periods, published in WSP 1313.

Average discharge. 30 years (1928-58), 1,249 cfs (904,200 acre-ft per year).

Extremes. Maximum daily discharge during year, 1,970 cfs Jan. 9; minimum daily, 126 cfs

1930-58: 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 below 900 cfs, which are good. Discharge computed as difference between discharge of Yuma Main Canal at siphon-drop powerplant 

and that of same canal below Colorado River siphon, with deduction for small irrigation diversions from canal between those stations. Records do not include flow 

of Reservation Canal Main Drain No. 4 which discharges into the wasteway a quarter 

of a mile above its mouth.

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

of Reclamation.

Discharge, in cubic feet per second, water year October 1957 to September 1953

5255. Yuma Main Canal below Colorado River siphon, at Yuma, Ariz.

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

intake, lat 32°43'50", long 114°37'10", in SW^SE^ 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-J miles downstream from siphon-drop powerplant. 

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

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

bridge over Colorado River at Yuma.

Records available. January 1924 to September 1958. Monthly discharge only prior to October 1938, published in WSP 1313. Diversion from Yuma Main Canal for municipal supply 

for Yuma, October 1947 to September 1958 (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. 34 years, 476 cfs (344,600 acre-ft per year).

Extremes. Maximum daily discharge during year, 791 cfs July 24; minimum daily, 24 cfs 

January 6-9.

1930-58: Maximum daily discharge, 882 cfs (corrected) Aug. 15, 1952; no flow for 

short periods 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.

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, 8,350 cfs Jan. 26; no flow many days.

T9~39-58: Maximum daily discharge, that of Jan. 26, 1958; no flow for long periods.

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

T720~0 prior to Apr. 1 and good above 1,000 cfs and fair below thereafter. Daily 

discharge computed from head, and 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 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. See table below for monthly return flow 

by Pilot Knob wasteway only.

480 DIVERSIONS AND RETURN FLOWS AT AND BELOW IMPERIAL DAM 

Return surface flows from Yuma project, Arlz-Calif.

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

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

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

through the All-American Canal. Also see records of Yuma Main Canal at siphon-drop 

powerplant and below Colorado River siphon.

The Reservation Canal Main Drain No. 4 and Drain 8-B in the Reservation Division and 

the Cooper, Eleven-Mile, and Twenty-one Mile wasteways in the Valley Division return 

surface flows to the Colorado River. Water collected by the Main drain and East Main 

canal in the Valley Division is delivered across the international boundary for use in 

Mexico. None of. this water is included in the record of the Colorado River at Yuma.

Reservation Canal Main Drain No. 4.

Location. Water-stage recorder 500 ft upstream from crossing of U. S. Highway 80.

DISCHARGE AT PARTIAL-RECORD STATIONS AND MISCELLANEOUS SITES 483

As the number of streams on which streamflow information is likely to be desired far 

exceeds the number of stream-gaging stations feasible to operate at one time, the Geological Survey collects limited streamflow data at sites other than stream-gaging stations. 

When limited streamflow data are collected on a systematic basis over a period of years 

for use in hydrologic analyses, the site at which the data are collected is called a 

partial-record station. Data collected at these partial-record stations are usable in 

low-flow or flood-flow analyses, depending on the type of data collected. In addition, 

discharge measurements are made at other sites not included in the partial-record program. 

These measurements are generally made in times of drought or flood to give better areal 

coverage to those events. Those measurements and others collected for some special reason 

are called measurements at miscellaneous sites.

Records collected at partial-record stations are presented in two tables. The first 

is a table of discharge measurements at low-flow partial-record stations, and the second 

is a table of annual maximum stage and discharge at crest-stage stations. Discharge measurements made at miscellaneous sites for both low flow and high flow are given in a third 

table.

Low-flow partial-record stations

Measurements of streamflow in the area covered by this report made at low-flow, partialrecord stations are given In the following table. Most of these measurements were made 

during periods of base flow when streamflow is primarily from ground-water storage. These 

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

The column headed "Period of record" shows the water years in which measurements were made 

at the same, or practically the same, site.

484 DISCHARGE AT PARTIAL-RECORD STATIONS AND MISCELLANEOUS SITES

Crest-stage partial-record stations

The following table contains annual maximum discharges for crest-stage stations. A 

crest-stage gage is a device which will register the peak stage occurring between inspections of the gage. A stage-discharge relation for each gage is developed from discharge 

measurements made by indirect measurements of peak flow or by current meter. The date of 

the maximum discharge is not always certain but is usually determined by comparison with 

nearby continuous-record stations, weather records, or local inquiry. Only the maximum 

discharge for each water year is given. Information on some lower floods may have been 

obtained but is not published herein. The years given in the period of record represent 

water years for which the annual maximum has been determined. The maximum discharge for 

each year since the crest-stage gage was established is given. The peak discharge for 

some years may have been published in a previous report as a measurement of discharge. 

Figures given herein supersede all previous figures of peak discharge for the floods 

listed.
