SURFACE WATER SUPPLY OP THE COLORADO RIVER BASIN, 1959

SCOPE OF WORK

This volume is one of a series of 20 reports presenting records of stage, discharge, 

and content of streams, lakes, and reservoirs in the United States during the 1959 water 

year. Since 1888, when the United States Geological Survey first studied streamflow in 

relation to problems of irrigation, similar records have been obtained at more than 

15,200 gaging stations in the 50 States. On September 30, 1959, the Geological Survey and 

cooperating organizations were maintaining 7,110 gaging stations. 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 1959 water 

year 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availability of electronic computer results, and other unpublished data concerning the 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 for 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 usei 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 seiond 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 3 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 saire 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 cf both types
4 SURFACE WATER SUPPLY, 1959, 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 

includes the part number, but the station number 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 to the left of the hyphen is the part number; it is 9 for 

all stations in this report, with one exception, and is therefore omitted. The exception 

is the transmountain diversion from Sevier Lake basin which is numbered as a part 10 station. For this station the "10-" is shown in the station number.

EXPLANATION OP 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 tickwater 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 ant5 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 ueual 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 ard engineers, and 

comparable records of discharge for other stations in the same or nearby basins. If the
EXPLANATION OF 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 enda 

On September 30. A calendar for the water year 1959 is shown on page IV for tt~e purpose 

of finding the day of the week for any date.

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

type and history of gage3, 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 giver 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, location?, 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 fewer than five complete years of record or for stations whnre nhanges 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 extersive 

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 giver are for 

the periods of record within the calendar year dates in the heading {not necesrarily 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 discinrge 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 maximrm 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 usvally 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
6 SURFACE WATER SUPPLY, 1959, 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 th3 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 hsaded "Cfsm"), or 

in inches (line headed "in"), or in acre-feet (line headed "Ac-ft"). F.'.gures for cubic 

feet per second per square mile and runoff in inches are omitted if the drainage area 

includes large noncontributing areas, or if the average annual rainfall over the drainage 

basin is usually less than 20 inches.

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

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

Peak discharges and the time of their occurrence and corresponding gage heights of most 

stations are listed below the table of daily and monthly dischartre. All independent peaks
ACCURACY OF 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 vrhich the 

peaks are subject to substantial control by man.

Footnotes to the table of daily discharge indicate periods when discharge ras 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 frequerny 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-ofrwater 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 temperatur3 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, 1959, 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 ir contents of 

reservoirs, or for other changes incident to use and control. Evaporatior 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 tte discharge 

recorded does not actually show the water supply available at the station? for further 

development, because water must first be supplied to existing irrigation systems.

PUBLICATIONS

Basic data for gaging stations are published in an annual series of reports consisting 

of 20 volumes, including one each for the States of Alaska and Hawaii. The area of the 

other 48 States is divided into 14 parts whose boundaries coincide with certain natural 

drainage lines. Formerly, the annual series of reports on surface-water supply consisted 

of 14 volumes, one £ or each of the 14 parts. Beginning with the reports for 1951, the 

records for the 48 States were published in 18 volumes, there being 2 voluues each for 

Parts 1, 2, 3, and 6. The boundaries of the various parts are indicated b7 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 8 areas ranging 

from 18 to 36,900 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 9| miles east of Tucson, Ariz.

HYDROLOGIC CONDITIONS

Runoff was generally median to deficient during the year except at times when it was 

excessive in scattered areas, particularly in Arizona. New monthly low runoff occurred in 

the following streams: San Juan River near Bluff, Utah, for March and May, SaA Juan River 

at Farmington, N. Mex., for March, Colorado River near Cisco, Utah, for April, and Salt 

River near Roosevelt, Ariz., for June. Near record lows occurred at other times in these 

or other streams In the Little Colorado River and Virgin River basins, Ariz., and the 

Green River basin, Utah. No noteworthy floods occurred during the year.

Figure 2 on page 12, for which records of three long-term gaging stations were used, 

shows a comparison of the monthly and yearly mean discharges for the 1959 water year with 

the median discharge for the period 1921-45.

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.--26 years (1933-59), 32.3 cfs (23,380 acre-ft per year), including 

diversions to Moffat water tunnel.

Extremes. Maximum discharge during year, 88 cfs June 8 (gage height, 1.79 ft); minimum 

daily, 0.1 cfs July 14, 22-24.

1933-59; 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 fair except those for periods of ice effect or no gage-height record, 

which are poor. Transmountain diversions above station to Moffat water tunnel was 

18,740 acre-ft during water year 1959.

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

1929. Jan. 1, 1911, to Feb. 23, 1915, staff gage at bridge 1,800 ft upstream at different datum. Feb. 24, 1915, to Sept. 30, 1921, staff gage and Apr. 24; 1932, to 

Oct. 5, 1935, water-stage recorder, at bridge half a mile downstream at different datum.

Average discharge. 39 years, 153 cfs (110,800 acre-ft per year), including diversions by 

Twin Lakes tunnel.

Extremes. Maximum discharge during year, 1,020 cfs June 17 (gage height, 3.93 ft); minimum daily, 6.7 cfs Sept. 6-8.

1910-21, 1931-59: Maximum discharge, 3,170 cfs June 18, 1917 (gage height, 7.2 ft, 

site and datum then in use, from floodmarks), from rating curve extended above 1,200 

cfs; minimum daily prior to construction of Twin Lakes tunnel, 15 cfs July 15, 16, 

1934; minimum daily since diversion through Twin Lakes tunnel, 0.4 cfs Sept. 24, 27 

28, 1956.

Remarks.--Records good except those for periods of ice effect, which are fair. Transmountain diversion 15 miles upstream through Twin Lakes tunnel to Arkansas River basin 

since May 24, 1935 (see p. 327). Salvation ditch diverts water above station for irrigation of about 1,000 acres below.

Revision (water years). WSP 1313: 1934(M) .

recorder at site 180 ft downstream at same datum. May 9, 1941, to Apr. 25, 1946, 

chain gage at site 100 ft downstream at same datum.

Average discharge.--33 years (1907-8, 1920-21, 1938-59), 275 cfs (199,100 acre-ft per 

year).

Extremes.--Maximum discharge during year, 1,080 cfs June 10 (gage height, 4.80 ft); minimum daily, 30 cfs Mar. 16.

1903-31, 1938-59: Maximum discharge recorded, 3,730 cfs May 5, 1941 (gage height, 

5.90 ft, site and datum then in use), from rating curve extended above 1,900 cfs; no 

flow at times in 1908; minimum daily determined since beginning of diversion through 

Gunnison tunnel, 7 cfs July 10-15, 17, 21, 24-28, 1910.

Remarks.--Records good. Natural flow of stream affected by water diverted from Gunnison 

River (see record of diversion with record for Gunnison River below Gunnison tunnel, 

p. 105) and other adjacent basins, diversions for irrigation of about 90,000 acres 

above station, and return flow from irrigated areas.

Sept. 30, 1932, to Oct. 14, 1935, water-stage recorder, at site 300 ft upstream at 

different datum.

Average discharge (combined flow). 41 years, 40.9 cfs (29,610 acre-ft per year).

Extremes (combined flow).--Maximum discharge during year, 456 cfs May 15; minimum daily, 

8.5 cfs Dec. 30.

1917-21, 1922-59: Maximum discharge observed, 1,640 cfs June 6, 1921 (gage height, 

4.5 ft, site and datum then in use), from rating curve extended above 700 cfs; minimum 

daily, 4.3 cfs Dec. 19, 1939.

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

which are poor. Diversions above station for municipal supply of Grand Junction and 

by Raber ditch for irrigation of about 60 acres below station. Records of these 

diversions furnished by State engineer and monthly figures are adjusted to show total 

flow of stream. Regulation by a few small reservoirs above station.

b Stage-discharge relation affected by ice.

Note. No gage-height record Jan. 8-19, Jan. 22 to Feb. 9 (stage-discharge relation affected by 

ice during most of period); discharge estimated on basis of 2 discharge measuretients, weather records, and records for nearby stations.
GUMISON RIVER BASIN 127

1525. Gunnison River near Grand Junction, Colo.

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

bank of river and right bank of canal, half a mile downstream from point of diversion 

of Redlands power canal and 2 miles upstream from mouth and Grand Junction.

Drainage area. 8,020 sq mi, approximately.

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

September 1899, October 1901 to October 1906, October 1916 to September 1959. Monthly 

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

1901-6.

Gages. River: Water-stage recorder above gage height 0.85 ft and once-daily staff-gage 

readings below. Datum of gage is 4,555.14 ft above mean sea level, datum of 1929. 

Prior to Apr. 1, 1917, staff or chain gages at several sites 1-| miles downstream near 

mouth and 12 miles upstream at Whitewater at various daturas. 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). 51 years (1896-99, 1901-6, 1916-59), 2,662 cfs 

(1,927,000 acre-ft per year).

Extremes (combined flow). Maximum discharge during year, 7,160 cfs June 15; minimum 

dally, 256 cfs July 21.

1896-99, 1901-6, 1916-59: Maximum discharge observed, 35,700 cfs May 23, 1920 (gage 

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

July 20, 1934.

Remarks. Records good except those for periods of ice effect 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 Gunnison River. Records show combined flow cf river 

and Redlands power canal and except for about 40 cfs diverted below gage durirg 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 ecres 

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 1959 are given in WSP 1644.

Location.--Lat 40°53'10", long 109°54'10", in NE£ sec.28, T.2 N., R.18 E., on left bank 

350 "ft downstream from confluence of North and South Forks and 12 miles southwest of 

Manila.

Drainage area.--45.9 sq mi.

Records available.--October 1942, April 1943 to September 1959.

Gage.--Water-stage recorder. Altitude of gage is 8,680 ft (from topograohic map).

Average discharge.--16 years (1943-59), 12.9 cfs (9,340 acre-ft per year).

Extremes.--Maximum discharge during year, 36 cfs May 2 (gage height, 4.28 ft); minimum 

daily, 0.1 cfs Oct. 1 to Dec. 8.

1942-59: Maximum discharge, 1,020 cfs May 19, 1948 (gage height, 6.05 ft), from 

rating curve extended above 250 cfs; no flow Nov. 5-7, 9, 10,1956.

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

which are fair. Transbasin diversions by Sheep Creek canals above station (see 

p. 185,187). Since June 1954, water has been diverted from Carter Creek drainage to 

Sheep Creek above the Sheep Creek lower canal to increase the irrigation supply in 

that canal; flow at this station could also be affected. Some storage in several 

small mountain lakes.

Records available. April 1904 to October 1905, June 1910 to November 1912, April 1916 

to September 1959. Monthly discharge only for some periods, published in WS° 1313. 

No winter records prior to 1917.

Gage. Water-stage recorder. Datum of gage is 5,900.23 ft above mean sea level, datum 

of 1929. Prior to Apr. 24, 1916, staff or chain gage at Thornburgh Bridge 14 miles 

downstream at different datum. Apr. 24, 1916, to Nov. 3, 1917, chain gage and Nov. 4, 

1917, to Mar. 8, 1937, water-stage recorder, at site 700 ft downstream at datum 

0.92 ft higher prior to Oct. 1, 1932, and at present datum thereafter.

Average discharge. 43 years (1916-59), 1,580 cfs (1,144,000 acre-ft per year).

Extremes. Maximum discharge during year, 6,690 cfs June 10 (-gage height, 6.77 ft); minimum daily, 54 cfs Sept. 15.

1904-5, 1910-12, 1916-59: Maximum discharge observed, 17,900 cfs May 19, 1917 

(gage height, 10.4 ft, from floodmarks, site and datum then in use), from rating curve 

extended above 12,000 cfs; minimum daily, 2 cfs July 17-19, 1934.

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

flow of stream affected by transbasin diversions, numerous storage reservoirs, and 

diversions above station for irrigation of about 65,000 acres above and about 

800 acres below station. Records of chemical analyses and water temperatures for the 

water year 1959 are given in WSP 1644.

2665. Ashley Creek near Vernal, Utah

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

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

4^ miles upstream from Dry Fork, 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 1959. 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 1? 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. Nov. 14, 1917, to Sept. 30, 1942, water-stage 

recorder at present site at datum 5.00 ft lower.

Average discharge. 46 years (1913-59), 103 cfs (74,570 acre-ft per year).

Extremes. Maximum discharge during year, 581 cfs May 15 (gage height, 1.81 ft); minimum, 

15 cfs Jan. 20-28, Jan. 31 to Feb. 2, Feb. 6,7.

1911-59: Maximum discharge, 2,050 cfs May 29, 1921, from rating curve extended 

above 860 cfs; maximum gage height, 4.05 ft June 16, 1929, present datum; minimum discharge, 13 cfs Apr. 26, 1957.

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

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 (diversion began Aug. 1, 1941); at.times, part of this 

flow is returned to Ashley Creek half a mile below station.

, . . , 

stage recorder at present site at datum 1.14 ft higher.

Average discharge. 31 years (1925-26, 1929-59), 171 cfs (123,800 acre-ft per year).

Extremes. Maximum discharge during year, 1,100 cfs June 7 (gage height, 3.95 ft); minimum recorded, 39 cfs Mar. 20 (result of powerplant regulation).

1929-59: 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 ice effect or 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. Discharge measurements , in cubic 

feet per second, during the water year 1959, of Pole Creek canal are as follows:

site at datum 3 ft higher.

Average discharge. 23 years (1909-18, 1945-59), 190 cfs (137,600 acre-ft per yaar).

Extremes. Maximum discharge during year, 687 cfs Sept. 17 (gage height, 5.44 f 1:); minimum daily determined, 0.1 cfs Aug. 31, Sept. 8, 14, 15.

1909-20, 1945-59: Maximum discharge, 12,000 cfs Sept. 2, 1909 (gage height, 

12.7 ft, site and datum then in use), from rating curve extended above 3,100 cfs by 

logarithmic plotting; no flow at times.

Remarks. Records good except those for periods of ice effect, fragmentary or no gageheight record, and those computed from once-daily staff-gage readings, which are fair. 

Discharge measurements generally made once a week. Diversions above station for 

irrigation of about 42,000 acres. Several small transmountain diversions from tributaries for irrigation in Sevier Lake basin. Records of chemical analyses, suspended 

sediment loads, and water temperatures for water year 1959 are given in WSP 1644.

Revisions (water years). WSP 1213: 1950. WSP 1343: 1909-12(M), 1917(M).

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

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

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

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

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

indefinite stage-discharge relation, which are poor. Discharge measurements generally 

made 3 to 5 times a month. Diversions above station for irrigation of about 52,000 

acres, 2,000 of which are below station. Records of suspended sediment loads and 

water temperatures for the water year 1959 are given in WSP 1644.

of 1929. Prior to May 1, 1920, staff gage and May 1, 1920, to May 24, 1927, waterstage recorder, at several sites about 600 ft downstream at different datums. 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. 43 years (1905-6, 1917-59), 46.4 cfs (33,590 acre-ft per year).

Extremes. Maximum discharge during year, 152 cfs May 15 (gage height, 1.90 ft); minimum 

not determined.

1904-6, 1910, 1917-59: Maximum discharge, 1,880 cfs Sept. 22, 1941 (gage height, 

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

Maximum flood known occurred Oct. 5, 1911.

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. One diversion 

above station for irrigation of about 2,000 acres along Cherry Creek below station.

324 SAM JUAN RIVER BASIN

3795. San Juan River near Bluff, Utah

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

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

Drainage area. 23,000 sq mi, approximately.

Records available.--October 1914 to September 1959. Monthly discharge only for some 

periods, published in WSP 1313.

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

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

datums.

Average discharge.--45 years, 2,793 cfs (2,022,000 acre-ft per year).

Extremes. Maximum discharge during year, 5,370 cfs Aug. 8 (gage height, 7.96 ft); minimum observed, 21 cfs July 29.

1914-17, 1927-59: Maximum discharge, 70,000 cfs Sept. 10, 1927 (gage height, 

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

Aug. 24-27, 29, 1939.

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

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

determined.

Remarks.--Records excellent except those for periods of fragmentary or ro gage-height 

record or those computed from once-daily staff-gage readings, which are fair. Discharge measurements generally made five times a week. Diversions for irrigation of 

about 190,000 acres above station. No diversion between station and mouth of river. 

Records of chemical analyses, suspended sediment loads, and water teirperatures for 

the water year 1959 are given in WSP 1644.

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

COLORADO RIVER MAIN STEM 325

3800. Colorado River at Lees Ferry, Aria.

Location. Lat 36°51'55", long 111°35'15", in NE^SE^ see.13, T.40 N., R.7 E., on left bank: 

at head of Marble Gorge at Lees Perry, just upstream from Paria River, 16 miles downstream from site of Glen Canyon Dam, 28 miles downstream from Utah-Arisona 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 1959. Calendar year estimates ard 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.--48 years (1911-59), 18,090 cfs (13,100,000 acre-ft per year).

Extremes.--Maximum discharge during year, 38,900 cfs June 19 (gage height, 12.53 ft); minimum, 2,810 cfs Sept. 17 (gage height, 5.89 ft).

1921-59: Maximum discharge, 220,000 cfs June 18, 1921 (gage height, 26.£ ft, from 

floodirarks), 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. Discharge measurements generally made once a week. 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 1959 are given in WSP 1644.

flow at times.

Remarks. Records good. Record since 1953 shows flow below Lake Show Low in Show Low 

C~rlJek. No flow this year over spillway of Jaques Dam. Flow regulated by several 

reservoirs, largest of which are Lake Show Low, completed in 1953; Lakeside Reservoir, 

completed prior to 1941; and Scott Reservoir, completed in 1946 (combined capacity, 

8,800 acre-ft). Diversions for irrigation of about 200 acres above Lake Show Low and 

diversion by pumping of floodwater stored in Lake Show Low to Forestdale Creek in 

Salt River basin (see record for Forestdale Creek diversions from Show Low Creek, near 

Show Low).

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., 4| miles southeast of Show Low; dam completed and storage began in spring of 1953. Total capacity, 6.176 acre-ft, consisting of 1,070 acre-ft dead storage below elevation 6,535.0 ft (sill of outlet structure), and 5,106 acre-ft usable storage between elevations 6,535.0 and 6,570.0 ft 

(sill of overflow spillway). Capacity table prepared by Leeds, Hill, and Jewett, 

Consulting Engineers, from surveys by the firm. Water cannot be pumped when lake 

elevation is below 6,538.5 ft (sill of intake to pumping plant) but can be released 

to river channel down to elevation 6,535.0 ft. There was no diversion by pumping to 

Forestdale Creek this year. Elevations obtained periodically by Navapache Electric 

Co-operative, Inc. and monthly by Geological Survey.

342 LITTLE COLORADO RIVER BASIN

3970. Little Colorado River at Holbrook, Ariz.

Location. Lat 34°53i50", long 110°09'40", in SW^SW^- sec.6, T.17 H., R.21 E., near right 

bank on downstream side of bridge on U. S. Highway 260 at Holbrook, 2? miles downstream from Puerco River.

Drainage area. 11,300 sq mi, approximately.

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

only), September 1949 to September 1959.

Average discharge. 11 years (1905-6, 1949-59), 95.5 cfs (69,140 acre-ft per year); 

median of yearly mean discharges, 85 cfs (61,500 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, 6,300 cfs Aug. 6, 9 (gage height, 8.95 ft); no 

flow for part of several days.

1905-9, 1949-59: Maximum discharge determined, 21,800 cfs Aug. 5, 1957 (gage 

height, 10.96 ft); maximum daily, 20,200 cfs Nov. 27, 1905; no flow et 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 good except those for periods of ice effect and those after Aug. 8, 

which are fair, and those for periods of doubtful or no gage-height record, which are 

poor. Diversions above station for Irrigation of about 23,000 acres. Some regulation by reservoirs (combined capacity, about 73,000 acre-ft).

COLORADO RIVER MAIN STEM 351

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 1959. 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 S.418.7 ft above mean sea level; preliminary datum 

of 1929.

Average discharge. 37 years, 17,110 cfs (IS,390,000 acre-ft per year).

Extremes.--Maximum discharge during year, 38,300 cfs June 19 (gage height, 16.11 ft); minimum, 3,290 cfs Sept. 18.

1922-59: 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 Perry). 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 no gage-height record, w'lich 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 1959 are given in WSP 1644.

4150. Virgin River at Littlefield, Ariz.

Location. Lat 36-53', long 113°56', in SW&3WJ sec.4, T.40 N., R.15 W., on right bank 

three-eighths of a mile downstream from Beaver Dam Wash, three-eighths of a mile 

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

elevation 1,221 ft above mean sea level.

Drainage area. 5,090 sq mi, approximately. 

Records available. October 1929 to September 1959.

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

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

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

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

Average discharge. 30 years, 240 cfs (173,800 acre-ft per year); median of yearly mean 

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

Extremes. Maximum discharge during year, 3,490 cfs Aug. 19 (gage height, 7.76 ft); minimum, 55 cfs July 23.

1929-59: Maximum discharge, 22,000 cfs Mar. 3, 1938, by slope-area measurement of 

peak flow; maximum gage height, 13.60 ft Aug. 25, 1955; minimum discharge observed, 

about 50 cfs for many days in several years, resulting from nearby fairly uniform 

spring inflow.

Remarks. Records good except those for periods of doubtful gage-height record, which are 

fair. Diversions above station for irrigation of about 23,200 acres. Records of 

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

year 1959 are given in WSP 1644.

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

Records available. Contents: February 1935 to September 1959. Evaporation: March 1952 

to September 1959. Published as Lake Mead at Boulder Dam prior to 1946.

. Water-stage recorder. Prior to Oct. 1, 1952, daily readings of indicator. Datum 

of gage is 0.40 ft above mean sea level,' datum of 1929, leveling of 1950; used locally 

as at mean sea level, powerhouse datum, based on adjustment uf 1912.

Extremes. Maximum contents during year, 23,320,000 acre-ft Oct. 1 (gage height, 1,195.53 

ft); minimum, 20,036,000 acre-ft Sept. 30 (gage height, 1,171,13 ft).

1935-59: Maximum contents, 27.790,000 acre-ft July 29, 30, 1941 (gage height, 

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

1,083.21 ft).

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

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

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

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

1,221.4 ft (top of automatic spillway gates in raised position); and uncontrolled storage, 1,220,000 acre-ft between gage heights 1,221.4 and 1,229.0 ft. Reservoir is used 

to store water for flood control, irrigation, municipal water supply, and power development. Figures given herein represent usable contents.

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

Henderson and Las Vegas, Nev., area for municipal and industrial use. Discharge measured by venturi meters. Diversion started Apr. 7, 1942. First diversion to Las Vegas 

Valley Water District occurred October 1956. Two pumping plants in the Nevada side of 

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

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

1932 but records available only since October 1935.

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

Colorado River Commission of Nevada.

COLORADO RIVER MAIN STEM 373 

4240. Colorado River near Topock, Ariz.

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

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

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

Drainage area. 172,300 sq mi, approximately.

Records available. January 1917 to September 1959. Daily mean elevations published 

since October 1938.

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

T929; 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); 

25 years"(1934-59), 14,150 cfs (10,240,000 acre-ft per year), unadjusted.

Extremes. Maximum discharge during year, 18,200 cfs July 9; maximum elevation, 457.37 ft 

July 9; minimum discharge, 8,690 cfs Nov. 2; minimum elevation, 453.22 ft Nov. 2.

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

1,480 cfs Aug. 17, 1934.

1934-59: Maximum discharge, 35,700 cfs Jan. 29, 1942; maximum elevation, that of 

July 9, 1959; minimum discharge, 375 cfs Feb. 14, 1935; minimum daily, 422 cfs Feb. 14, 

1935.

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.

Remarks. Records excellent. Discharge measurements generally made about four times a 

month prior to June 1, twice a month thereafter. Many diversions above station for 

irrigation, municipal, and industrial uses. Flow regulated by Lake Mead since 

Feb. 1, 1935, and by Lake Mohave since Jan. 17, 1950. Records of water temperatures 

for the water year 1959 are given in WSP 1644.

Revisions (water years). WSP 918: 1921. WSP 1313: 1918-19(M).

376 BILL WILLIAMS RIVER BASIN

4260. Bill Williams River near Alamo, Ariz.

Location. Lat 34°14', long 113"35' , in SW£NW£ sec.2, T.10 N., R.13 W., on left bank 

1.5 miles downstream from Alamo, 2.0 miles downstream from Bullard Wash, and 6 miles 

downstream from confluence of Santa Maria and Big Sandy Rivers.

Drainage area. 4.730 sq mi, approximately, of which 400 sq mi is below confluence of 

Santa Maria and Big Sandy Rivers.

Records available.--October 1939 to September 1959. Monthly discharge only for some 

periods, published in WSP 1313. Prior to October 1943, published as Williams River 

near Alamo.

Gage. Water-stage recorder. Datum of gage is 1,002.95 ft above mean ssa level, datum 

of 1929. Supplementary water-stage recorder at site 300 ft downstream at datum 

0.51 ft higher since Apr. 18, 1955.

Average discharge. 20 years, 95.7 cfs (69,280 acre-ft per year); median of yearly mean 

discharges, 46 cfs (33,300 acre-ft per year).

Extremes.--Maximum discharge during year, 2,900 cfs Aug. 18 (gage height, 4.99 ft, 

supplementary gage); minimum daily, 2.0 cfs Oct. 23.

1939-59: Maximum discharge, 65,100 cfs Aug. 29, 1951 (gage height, 30.8 ft); minimum daily, 1.1 cfs Sept. 4, 1958.

Flood of Sept. 6, 1939, reached a stage of 39.6 ft, from floodmarks (discharge, 

86,000 cfs, from rating curve extended above 50,000 cfs on basis of slope-area measurement of peak flow made just below confluence of Santa Maria and Big Sandy Rivers). 

Ploodmarks indicate a previous stage of about 46 ft.

Remarks.--Records fair except those for periods of doubtful gage-height record, which 

are poor. Diversions above station for irrigation of about 5,000 acres, most of which 

is irrigated by pumpage from ground water.

Revisions (water years). WSP 1213: 1939(M), 1941(P).

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 1959 (monthly diversions only after October 

1942). Published as a supplement to records for Colorado River below Parker Para, 

1942-50.

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

Average discharge. 80 years, 318 cfs (230,200 acre-ft per year).

Extremes.--1939-59: Maximum daily diversion, 1,310 ofs Aug. 6, 1959; no diversion at 

times.

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

pumped from Havasu Lake, less return surface flow from Gene and Copper Basin Feservoirs. No water returned as surface flow from either reservoir since 1941 except in 

1953, 1956, Dec. 14, 15, 1958, Feb. 12, 1959 (8,272 acre-ft was returned during the 

water year 1959). During this year 4,983 acre-ft (partly estimated) of coolirg 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 ebout 

1 mile from Colorado River. Percolation amounted to 5,110 acre-ft during the water 

year and was not subtracted from the diversion record.

378 COLORADO RIVER MAIM STEM

4275. Havasu Lake near Parker Dam, Ariz.-Calif.

Location. Lat 34"19'00", long 114°09'23", in NW£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 Colorado 

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 1959. Published as Parker Reservoir near 

Parker Dam 1938.

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

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

Extremes. Maximum contents during year, 617,800 acre-ft May 7 (elevation, 450.46 ft); 

minimum, 537,300 acre-ft Feb. 16 (elevation, 446.24 ft).

1938-59: Maximum contents, 693,000 acre-ft (by temporary use of flashboards) 

Apr, 18, 1943, June 4, 1953; maximum elevation, 450.77 ft 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, 

rSSF. 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 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 C.07 ft fall indicated between gage and Parker Dam under normal operating conditions. Drawdown below 

elevation 440.54 ft not legally permissible except by consent of the Metropolitan 

Water District of Southern California or in an emergency affecting safety of the dam. 

Lake is used for flood control, power development, re-regulation of river for irrigation demand, and as a basin from which water is pumped by Metropolitan Water District 

of Southern California to Colorado River aqueduct. Figures given herein represent 

usable contents. For record of diversion to Colorado River aqueduct and return flow, 

see record for Colorado River aqueduct near Parker Dam, preceding page.

Corrections. Figures in table of usable contents for the water year 1958 were erroneously 

published as thousands of acre-feet; figures are in acre-feet.

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

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

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

at Yuma, 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 14^ miles upstream at datum 167.38 ft above 

mean sea level, datum of 1929.

Average discharge (unadjusted).--35 years (1934-59), 12,990 cfs (9,404,000 acre-ft per 

year).

Extremes. Maximum daily discharge during year, 16,300 cfs Aug. 5; minimum daily, 7,910 

cfs Nov. 7 .

1934-59: Maximum discharge, 40,800 cfs Sept. 5, 1939; minimum, 538 cfs Aug. 3, 

1934; minimum daily since regulation of Hoover Dam began, 1,450 cfs Feb. 17, 1935.

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

diversions in vicinity of Yuma. Many diversions from Colorado River and tributaries 

upstream. Flow regulated by many reservoirs, principally Lake Mead, since 1935.

Location.--Duncan Valley lies along Gila River in Hidalgo County, N. Hex., 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 valtey, is 6 miles downstream 

from station on Gila River below Blue Creek, near Virden, N. Hex. 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 1959 (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 

are published on the following two pages of 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 puims 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 include1 in these records. 

Decreed area for irrigation for the valley is 8,061 acres. Water was issued for 6,865 

acres during 1959.

GILA RIVER BASIN 399

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

Location. Lat 33°04'00", long 109°26'45", in SEvNE£ 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 1959.

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

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

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

75 ft downstream at different datum.

Average discharge. 15 years, 33.1 cfs (23,960 acre-ft per year), unadjusted; median of 

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

Extremes. Maximum discharge during year, 4,780 cfs Aug. 17 (gage height, 7.2E ft, at 

supplementary gage); minimum, 8.9 cfs July 2.

1944-59: Maximum discharge, 6,150 cfs Sept. 10, 1958 (gage height, 8.1 ft, at 

supplementary gage); 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 50 cfs, which are fair, and those for

periods of no gage-height record, which are poor. Diversions above statior for irrigation of about 500 acres, mostly above Willow Creek. Water from Black River was pumped 

into Eagle Creek basin, 51J miles upstream from this station, for about 6 ironths (see 

p. 395), and water was pumped from wells into Eagle Creek near Double Circle Ranch 

for about 5 months (see preceding page). Diversions by pumping for industrial and 

municipal use in and near Morenci and Clifton are made from Eagle Creek, 2f miles downstream from this station, and from San Francisco River near Clifton. The monthly 

quantities diverted are shown in the table below. Ninety-four 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, extending from vicinity 

of Bonita Creek on the east to San Carlos Indian Reservation on the wast. 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. 1936-59 (records of combined monthly diversions in Safford Valley, 

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

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

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

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

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

Remarks. 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. There was no miscellaneous direct pumping this year.

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 upstream from mouth of San Carlos River. Apr. 29, 1914, to Mar. 8, 1937, 

water-stage recorder at various sites within 1 mile upstream from present site at 

different datums.

Average discharge (adjusted for storage in San Carlos Reservoir). 47 years (1900-1901, 

1903-4, 1914-59), 360 cfs (260,600 acre-ft per yearj; median of yearly mean discharges, 

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

Extremes. Maximum discharge during year, 671 cfs June 29 (gage height, 3.04 ft); minimum 

daily, 1.0 cfs for several days.

Extremes. Maximum discharge during year, 1.300 cfs Oct. 6 (gage height, 5.95 ft); minimum, 

1.7 cfs Aug. 12.

1941-59: Maximum discharge, 55,000 cfs, of which 500 cfs was released at Coolidge 

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

basis of slope-area measurement of peak flow; no flow at times when Coolidge Dam is 

closed.

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

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

About 69,000 acres irrigated in the basin above Coolidge Dam, a considerable portion by 

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

4740. Gila River at Kelvin, Ariz.

Location. La t 33°06'10", long 110°58'45", in NW^NWi 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 19j miles upstream from Ashurst-Hayden Dam.

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

Records available . January 1911 to September 1959. 

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

1915. Supplementary water-stage recorder 900 ft upstream since May £7, 1951. 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. 

Average discharge (adjusted for storage in San Carlos Reservoir) . 48 years, 487 cfs

(352,600 acre-rt per year); median of yearly mean discharges, 340 cf& (246,000 acre-ft

per year) . 

Extremes . Maximum discharge during year 5,930 cfs Aug. 17; maximum gage height 8 47 ft

July 28; minimum daily discharge, 23 cfs Jan. 22, 23, July 15.

1911-59: Maximum discharge, about 132,000 cfs Jan. 20, 1916 (gage, height, 19.5 ft),

from rating curve extended above slope-area measurement at gage hgigl-t 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 periods of no gage-height record, which are poor.

Discharge measurements generally made three times a month. Large diversions above

station for irrigation, of which about 90 percent is above Coolidge lam. About

78,000 acres irrigated (in 1955), a considerable portion by pumping from ground water.

Plow regulated by San Carlos Reservoir (Coolidge Dam) after Nov. 15, 1928 (see p. 408);

no other regulation. San Pedro River contributes major portion of unregulated inflow.

Records of chemical analyses, suspended sediment loads, and water teirceratures for the

water year 1959 are given in WSP 1644.

GILA RIVER BASIN 415

4750. Gila River at Ashurst-Hayden Dam, near Florence, Ariz.

Location. Lat 33°06'00", long 111°14'50", in SW^NW^ sec.8, T.4 S., R.ll E., on left bank 

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

Drainage area. 18,305 sq mi.

Records available. July 1923 to September 1959 (head on crest of dam only). Rscords of 

monthly diversions to Florence-Casa Grande Canal, January 1928 to September 1959.

Gage. Water-stage recorder. Permanent crest of dam is 1,562.6 ft above mean S3a level,

"cfatuin 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, 2.34 ft July 28; no flow over dam most of year.

T9"23-59: Maximum head on dam, 8.0 ft Sept. 28, 1926; no flow over dam most of each 

year.

Remarks. Records show daily mean head on dam and monthly diversions to Florenc3-Casa

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

extensive sluicing. Plorence-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 Cirlos 

Reservoir. Diversions above station for irrigation of about 78,000 acres, a considerable portion of which is irrigated by pumping from ground water.

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

GILA RIVER BASIN

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

Location. Lat 32 0 13'00", long 110"57'00", in SW^NE^ sec. 18, T.14 S., R.14 E., on right 

bank at Vine Avenue, a quarter of a mile downstream from Arroyo Chico and 2f 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: August 1945 to June 1953, 

23.4 sq mi; June 1953 to June 1954, 18.1 sq mi; June 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 1959.

Gage. Water-stage recorder and concrete control, 

sea level (city of Tucson bench mark).

Datum of gage is 2,411.9 ft above mean

Average discharge. 8 years (1944-52), 0.68 cfs (492 acre-ft per year), representing flow 

from 23.4 sq mi.

Extremes. Maximum discharge during year, 2,540 cfs Aug. 20 (gage height, 8.52 ft); no 

flow for most of year.

1944-59: Maximum discharge, 4,100 cfs July 24, 1948 (gage height, 9.9 ft), from 

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

of peak flow; no flow for most of each year.

Remarks. Records good except those for periods 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 SE£ 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 NEtrSW-j sec.22, 

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

1,000 cfs.

430 GILA RIVER BASIN

4890. Santa Cruz River near Laveen, Ariz.

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

River Indian Reservation, on downstream side of highway bridge, 3.4 miles upstream 

from mouth, 4.3 miles south of Komatke, and 9 miles south of Laveen.

Drainage area. 8,581 sq mi.

Records available. January 1940 to September 1946, December 1947 to September 1959.

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

of 1929, Phoenix-Picacho supplementary adjustment of 1949.

Average discharge. 17 years (1940-46, 1948-59), 22.4 cfs (16,220 acre-ft per year); 

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

Extremes. Maximum discharge during year, 3,010 cfs Aug. 12 (gage height, 16.03 ft); no 

flow for many days.

1940-46, 1947-59: 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 the underground 

basin, for municipal uses and 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.

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

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

River; Roosevelt Lake, formed by Roosevelt Dam, in sec.20, T.4 N., R.12 E. (ursurveyedfc 

Apache Lake, formed by Horse Mesa Dam, 17 miles downstream from Roosevelt Dan; 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 1959. Prior to October 1934 month-end 

contents only, published in 1313. Evaporation: April 1958 to September 1959.

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, 811,000 acre-ft Feb. 26; minimum 

contents, 511,700 acre-ft Sept. 30.

1910-59: 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 Flat 1923-26; 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.

5075. Fossil Creek diversions to Childs power-plant, near Camp Verd°, Ariz.

Location. Lat 34°22'05", long 111°39'55", in NE^SW^ sec.20, T.ll| 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 1959.

Gage.--Water-stage recorder and weir in concrete flume. Altitude of gage is 3,730 ft 

(from topographic map).

Extremes. Maximum daily discharge during year, 47 cfs Sept. 5; minimum, 36 cfs Oct. 1-5,

1952-59: Maximum daily discharge, 51 cfs Apr. 17-21, 1952; no flow for short 

periods in most years.

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

ancTshows 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 powerplant and was measured as 

follows: Oct. 16, 0.61 cfs; Dec. 18, 0.74 cfs; Apr. 30, 0.81 cfs; May 29, 0.75 cfs; 

June 25, 0.27 cfs; and Sept. 3, 0.55 cfs. Based on these measurements, observations of 

no flow in Fossil Creek below Irving, and records for previous years, the flow through 

Irving powerplant is estimated as being equal to about 99 percent of the record published herewith.

5095. Reservoir system on Verde River at and below Horseshoe Dam, Ariz.

Location. This system comprises two storage reservoirs created by Horseshoe and Bartlett 

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

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

by Bartlett Dam, lat 33°49', long 111°38', in sec.34, T.6 N., R.7 E., unsurveyed.

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

Records available.--July 1939 to September 1959. Prior to 1946, publishsd as Bartlett 

Reservoir at Bartlett Dam.

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

1,900.00 ft and on Bartlett Reservoir 1,609.46 ft above mean sea level, datum of 1929.

Extremes. Maximum contents during year, 126,800 acre-ft Mar. 8, 9; minimum, 29,040 acre1939-59: Maximum contents, 310,100 acre-ft May 2, 1952; no storage at times when 

natural flow of river was passed through reservoir system.

Remarks. Horseshoe Reservoir is formed by earth- and rock-fill dam; dam completed and 

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

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

2 reservoirs is 322,300 acre-ft divided as follows; Horseshoe Reservoir, 142,800 acreft between elevations 1,915.0 (sill outlet gate) and 2,026.0 ft (top of spillway gates); 

Bartlett Reservoir, 179,500 acre-ft between elevation 1,619.46 (10 ft above sill of 

outlet gates) and 1,797.46 ft (top of spillway gates). No dead storage. Records given 

herein represent usable contents. Water is used for irrigation of Salt River Valley

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

Location. Lat 33°51», long 112°16', in NW£ sec.21, T.6 N., R.I E., at left u;stream end 

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

River.

Drainage area. 1,459 sq mi.

Records available. November 1910 to September 1914 (gage heights only), Octot°r 1914 to 

September 1919, October 1919 to September 1924 (gage heights only), October 1933 to 

September 1959 (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 1-J- miles downstream from 

Lake Pleasant Dam, at different datum.

Average discharge. 31 years (1914-19, 1933-59), 91.0 cfs (65,880 acre-ft per year); 

median of yearly mean discharges, 42 cfs (30,400 acre-ft per year).

Extremes. 1910-24, 1933-59: 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 summer 

of several years.

Remarks. Records fair. Figures given herein represent flow into Lake Pleasart. 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 hydrograrh. 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 l\ 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.

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

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

^datum of 1929.

Extremes.--Maximum contents during year, 21,580 acre-ft Aug. 26 (gage height, 102.96 ft); 

minimum, 10,580 acre-ft Aug. 1.

1928-59: 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.

GILA RIVER BASIN 467

5195. Gila River below Gillespie Dam, Ariz.

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

of Gillespie Dam, 8 miles downstream from Hassayampa River. 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 1959 (river below dam only). Records for

Gila Bend Canal May 1935 to September 1959 (since October 1941, monthly discharge only); 

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

estimates only), October 1939 to September 1959 (since October 1941, monthly discharge 

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

September 1959. Published as at Gillespie Dam" prior to 1939.

Gages. Gila River; Water-stage recorder since July 28, 1924. Datum of gage is 10.00 ft 

Below 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, 1939, 600 ft dowrstream from 

intake.

Average discharge (river below dam). 18 years (1941-59), 27.2 cfs (19,690 acre-ft per 

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

Extremes. Maximum discharge over dam during year, 480 cfs Aug. 17 (gage height, 10.22 ft); 

no flow for most of year.

1921-59: 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 except those for period of indefinite stage-discharge relation, 

which are poor. Records include flow over crest and through sluice gates of Gillespie 

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

immediately above dam. Other large diversions above station for irrigation, municipal, 

and industrial use. Flow of Gila River and tributaries above this station is regulated 

by San Carlos Reservoir on Gila River (capacity, 1,205,000 acre-ft), by a series of 

reservoirs on Salt River (capacity, 1,755,000 acre-ft), by Bartlett and Horseshoe 

Reservoirs on Verde River (capacity, 322,300 acre-ft), and by Lake Pleasant on Agua 

Fria River (capacity, 163,800 acre-ft). 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 tables below. 

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

for the water year 1959 are given in WSP 1644.

Revisions (water years).--WSP 1213: 1939. WSP 1243: 1924(M). WSP 1283: Drainage area.

GILA RIVER BASIN 469

5205. Gila River near Dome, Ariz.

Location. Lat 32°45'40", long 114°25'10", in SWf sec.4, T.8 S., R.2I 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 1959. Monthly discharge only for some periods, published in WSP 1313. Published as "at Yuma and Gila City" 1903, as "near Gila 

City" 1904, and as "at Dome (Gila City)" 1905-6. Records for 1907-29 are fublished 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 192?, no gage; 

discharge estimated. October 1903 to December 1906, principal staff gage * 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, 802 cfs Aug. 8 (gage height, 9.45 ft); no flow 

for many days.

1929-59: Maximum discharge, 20,700 cfs Feb. 15, 1932 (gage height, 16.75 ft); no 

flow for part or all of each year.

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

Remarks. Records good except those below 10 cfs after Aug. 26, which are poor. 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 station Gila River below Gillefpie Dam).

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

Many diversions from Colorado River and tributaries. Principal diversions below 

Parker Dam are Colorado River Indian Reservation Canal, Palo Verde Canal, All-American 

Canal, and Gila Gravity Main Canal. Return flows entering downstream but above northerly 

international boundary are Yuma Main Canal wasteway, Reservation Canal Main Drain 

No. 4, Drain 8-B, and Pilot Knob powerplant and wasteway. See monthly table below 

for combined flow of river, Yuma Main Canal wasteway, and Reservatior Canal Main Drain 

No. 4. Flow of Colorado River regulated by Hoover, Davls, Parker, Headgate Rock, and 

to a small extent by Imperial, Palo Verde, and Laguna Dams. No regulation on Gila 

River below Painted Rock Dam. Records of chemical analyses for the irater year 1959

DIVERSIONS AND RETURN PLOWS AT AND BELOW IMPERIAL DAM 475

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

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

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

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

Records available. July 1926 to September 1959. Monthly discharge only prior to October 1938, published in WSP 1313. Diversions from Ail-American Canal and Yuma Main 

Canal above siphon-drop powerplant, October 1947 to September 1959 (monthly discharge 

only). Diversions from Yuma Main Canal between siphon-drop powerplant and Yama Main 

Canal wasteway, October 1940 to September 1959 (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. 33 years, 1,711 cfs (1,239,000 acre-ft per year).

Extremes. Maximum daily discharge during year, 2,020 cfs Dec. 25, 26; minimum daily, 

20 cfs Jan. 7.

1930-59: 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. Plow 

regulated by gates from Ail-American Canal to Yuma Main Canal. Records show quantity 

of water diverted from Ail-American Canal to Yuma Main Canal, except that "diverted 

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

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

downstream.

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

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

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

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

to irrigate about 10,600 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, year October 1958 to September 1959

5250. Yuma-Main Canal wasteway at Yuma, Ariz.

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

rnr3"2 044'00", long 114"37'20", in SW£SE£ sec.26, T.16 S., R,22 E., San Bernardino 

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

half a mile north of Yuma, and 3i 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 1959. Monthly discharge only for some periods, published in WSP 1313.

Average discharge. 31 years (1928-59), 1,253 cfs (907,100 acre-ft per year).

Extremes.--Maximum daily discharge during year, 1,950 cfs Dec. 25; minimum daily, 20 cfs

1930-59: Maximum daily discharge, 2,020 cfs Dec. 24, 25, 1948; m flow for several 

days in 1937-39, 1945, 1950.

Remarks. Records excellent except those below 900 cfs, which are good. Discharge computed as differences between discharge of Yuma Main Canal at siphon-'irop powerplant 

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

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

mile above its mouth.

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

Reclamation.

Discharge, in cubic feet per second, water year October 1958 to September 1959

DIVERSIONS AND RETURN PLOWS AT AND BELOW IMPERIAL DAM 

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

477

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 SWvSEij 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 85 miles downstream from siphon-drop powerplant. At 

Outlet, in NWij-NEt 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 1959. 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 1959 (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.--35 years, 476 cfs (344,600 acre-ft per year).

Extremes. Maximum daily discharge during year, 852 cfs July 24; no flow Jan. 5-7.

 1930-59: Maximum daily discharge, 882 cfs Aug. 15, 1952; no flow for short periods in 

most years.

Remarks. Records excellent except those between 50 and 200 cfs, which are good, and 

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

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

Discharge measurements made every two weeks with additional measurements to define 

unusual conditions. Records show quantity of water delivered through Coloralo River 

siphon for irrigation of 44,915 acres in the Valley Division of the Yuma project and 

for supplementary municipal supply for city of Yuma. Records of chemical analyses for 

the water year 1959 are given in WSP 1644.

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

furnished by Arizona Water Co. (prior to April 1955, Arizona Public Service Co.).

Discharge, in cubic feet per second, water year October 1958 to September 1959

5270. Pilot Knob powerplant and wasteway near Pilot Knob, Calif.

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

Bernardino meridian, 2 miles east of summit of Pilot Knob, 6 miles west of Yuma, Ariz., 

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

Records available. February 1939 to September 1959. Prior to October 1943, monthly dis-

 charge only, published in WSP 1313. Prior to October 1956, published as Pilot Knob 

wasteway near Pilot Knob, Calif.

Sage. --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 

bypass 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, 6,360 cfs Dec. 15; no flow for many days.

 T9"39-59: Maximum daily discharge, 8,350 cfs Jan. 26, 1958; no flow for long 

periods.

Remarks . Records excellent. Daily discharge computed from flow-meter equipment and head 

and openings on wasteway gates or from head and gate openings on wicket and wasteway 

gates. Discharge measurements generally made three times a month. 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 coiroleted 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.

Cooperation. Midnight readings of Aowmeter, recorder graph of forebay, and record of 

tailrace elevation and gate openings furnished by Imperial Irrigation District.

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

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

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

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

the Ail-American Canal. See also 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 Yuna.

WHITEWATER DRAW BASIN 

5375. Whitewater Draw near Douglas, Ariz.

Location. Lat 31°21'15", long 109°35'00", in SWpSE^ see.10, T.24 S., R.27 E., at downstream side of pier on bridge on 0. S. Highway 80, l| miles upstream from international boundary and 2 miles west of Douglas.

Drainage area. 1.023 sq mi.

Records available. August to October 1911 (gage heights and discharge measurements only), 

July to October 1912, January to June 1913, October 1913, December 1913 to June 1914, 

February to June 1915, October 1915 to September 1919, October 1919 to April 1922 

(gage heights and discharge measurements only), June 1930 to December 1933, May 1935 

to September 1959 (July 1954 to March 1955 monthly discharge only). Monthly discharge 

only for some periods, published in WSP 1313. Records for July to September, November 

1913, July 1914 to July 1915, July to September 1915, published in WSP 359, 389, 409, 

and 1049 have been found to be unreliable and should not be used. Published as White 

River near Douglas 1911 and as White Water River near Douglas 1912.

Gage. Water-stage recorder. Datum of gage is 3,906.94 ft above mean saa level, datum of 

T929, supplementary adjustment of 1958; prior to May 14, 1938, 0.03 ft higher. Prior 

to Apr. 30, 1922, staff gages at various sites between a quarter of a mile upstream and 

three-quarters of a mile downstream, at different datums.

Average discharge. 30 years (1915-19), 1930-33, 1935-46, 1947-59), 11.8 cfs (8,540

acre-ft per year); median of yearly mean discharges, 9.4 cfs (6,800 acre-ft per year).

Extremes. Maximum discharge during year, 2,760 cfs July 27 (gage heigl-t, 14.93 ft); no 

flow for many days.

1911-22, 1930-59: Maximum discharge, 5,060 cfs Aug. 7, 1955; maj-inrum gage height, 

that of July 27, 1959; no flow at times in most years.

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

which are poor. Diversions above station for irrigation of about 27,800 acres (in 

1953), mostly by pumping from ground water. Whitewater Draw discharges into Gulf of 

California through Yaqui River in Mexico. Record shows flow at international boundary, 

except for smelter waste water which joins stream below station.

Revisions. See Records available.

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, tte 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 r partialrecord 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 arerl 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 £ third 

table.

Low-flow partial-record stations

Measurements of streamflow in the area covered by this report made at low-flov, 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 storege. These 

measurements, when correlated with the simultaneous discharge of a nearby streair 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.

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 creststage 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.

SAN JUAN RIVER SEEPAGE INVESTIGATION

During the 1959 water year, three series of discharge measurements were made in the San Juan Rive

the reach between main-stem gaging stations at Farmington and Shiprock. Discharge past Farmington r

The second and third series were made between the main stem stations at Rosa and Shiprock.

The second series was made Dec. 2, 3, to investigate winter flow. Discharge past the Rosa gaging 

result of channel storage and release from ice upstream. Discharge at the Shiprock gage varied from 

The third series was made Sept. 14-17. Discharge in the reach above Los Pinos River as indicated 

from 100 to 86 cfs. Flow past Farmington was affected Sept. 16 by a temporary cofferdam in channel 

Farmington showed a gradual increase from 155 to 170 cfs.
