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 1960 water 

year. Since 1388, when the United States Geological Survey first studied streamflow in 

relation to problems of irrigation, similar records have been obtained at more than 15,500 

gaging stations in the 50 States. On September 30, 1960, the Geological Surve;r and cooperating organizations were maintaining 7,300 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 1960 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. Gaging-station 

records for the Upper Colorado River basin have been analyzed by electronic computer to 

give the number of days in each year that the daily discharge was between selected limits 

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

electronic computer results, and other unpublished data concerning the gaging-station records may generally be obtained from the district office.

DEFINITION OF TERMS AND ABBREVIATIONS

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

as follows:

Gaging station is a particular site on a stream, canal, lake, or reservoir where systematic observations of gage height or discharge are obtained. When used in connection with 

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

continuous record of discharge is obtained.

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

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

Cubic foot per second (cfs) is the rate of discharge of a stream whose channel is 

1 square foot in cross-sectional area and whose average velocity is 1 foot per second.
DOWNSTREAM ORDER AND STATION NUMBERS 3

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

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

is distributed uniformly in time and area.

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

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

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

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

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

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

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

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

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

Control designates a feature downstream from the gage that determines the stagedischarge relation at the gage. This feature may be a natural constriction of the channel, 

a long reach of the channel, or an artificial structure.

Contents is the volume of water in a reservoir. Unless otherwise indicatec1 , 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 ran'' of any 

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

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

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

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

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

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

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

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

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

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

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

order used in this report. In assigning station numbers, no distinction is ir^de between 

partial-record stations and regular gaging stations, so that the station numt?r for a 

partial-record station indicates downstream-order position in a list made up of both types
4 SURFACE WATER SUPPLY, 1960, 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 OF DATA

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

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

weather records , and other information are used to supplement base data in determining the 

daily flow. The records of stage are obtained either from direct readings on a nonrecording gage or from a water-stage recorder that gives a continuous record of fluctuations. 

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

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

methods are described in Water-Supply Paper 888 and are also outlined in standard textbooks on the measurement of stream discharge.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

used as a factor In the determination of discharge.

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

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

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

occasional winter discharge measurements, consideration being given to the available 

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

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

on September 30. A calendar for the water year 1960 is s'hown on page IV for the purpose 

of finding the day of the week for any date.

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

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

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

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

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

Corps of Engineers unless otherwise noted. Under "Records available" are given the periods for which there are published records generally equivalent to those at the present 

site. Under "Gage" are given the type of gage currently in use and the datum of the present gage above mean sea level, and a condensed history of the types, locations, and daturas 

of previous gages used during the period of records available. The reference to "datum of 

1929" and adjustments of other years are to the datum and adjustments of the U. S. Coast 

and Geodetic Survey. Under "Average discharge" is given the average discharge for the number of years indicated. It is not given for stations having fewer than five complete years 

of record or for stations where changes in water development during the period of record 

cause the figure to have little significance. Under "Extremes" are given the maximum discharge and gage height; the minimum discharge if there is little or no regulation; the minimum daily discharge if there is extensive regulation (also the minimum discharge if useful); and the minimum gage height (unless it is of no importance). In the first paragraph 

the data given are for the complete current water year unless otherwise specified. In the 

second paragraph, the data given are for the periods of record within the calendar year 

dates in the heading (not necessarily those for the complete years indicated by the heading 

dates). Reliable information concerning major floods that have occurred outside the period 

of record are given in the third or last paragraph under "Extremes." Unless otherwise 

qualified, the maximum discharge corresponds to the crest stage obtained by use of a waterstage recorder, a crest-stage gage, or a nonrecording gage read at the time of the crest. 

If the maximum gage height did not occur at the same time as the maximum discharge, it is 

given separately. Information pertaining to the accuracy of the records and conditions 

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

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

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

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

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

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

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

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

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

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

613923 O -61 -Z .
6 SURFACE WATER SUPPLY, 1960, PART 9

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

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

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

was first published is givea It should be noted that for all stations for w'lich 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 tto3 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 ths 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 obtainei 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 fne 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 tvice-daily 

readings, or to the mean gage height determined from gage-height graphs base! 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" giv?s the sum 

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

gives the average flow in cubic feet per second during the month. Discharge for the 

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

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

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

includes large 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 discharge. 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 which the 

peaks are subject to substantial control by man.

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

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

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

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

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

For most gaging stations on lakes and reservoirs the data presented comprise a description of the station and a monthly summary table of stage and contents. For some reservoirs 

a table showing daily contents or stage is given. A skeleton table of capacity at given 

stages is published each year for all reservoirs for which records are published on a 

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

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

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

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

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

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

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

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

"Remarks" paragraph in this report. At many gaging stations water temperature is obtained 

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

reported in the quality-of-water annual reports.

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

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

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

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

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

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

miscellaneous sites.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of streamflow data depends primarily on (1) the stability of the stagedischarge relation or, if the control is unstable, the frequency of discharge measurements, and (2) the accuracy of observations of stage, measurements of discharge, and 

interpretation of records.
8 SURFACE WATER SUPPLY, I960, 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 te less than 

5 percent; "good," less than 10 percent; "fair," less than 15 percent; and "poor," 

probably more than 15 percent. The records of monthly and yearly mean discharge and runoff are, in general, more nearly accurate than the daily records.

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

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

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

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

unless satisfactory adjustments can be made for diversions, for changes in contents of 

reservoirs, or for other changes incident to use and control. Evaporation from a reservoir is not included in the adjustments for changes in reservoir contents, unless it is so 

stated. Even at those stations where adjustments are made, large errors in computed runoff may occur when relatively large negative adjustments are made or when evaporation is 

large in comparison with the observed discharge.

Many gaging stations on streams in the irrigated areas of the United States are 

situated above most of the diversions from those streams, and therefore the discharge 

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

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

PUBLICATIONS

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 for each of the 14 parts. Beginning with the reports fcr 1951, the 

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

Parts 1, 2, 3, and 6. The boundaries of the various parts are indicated by the following 

list and the map in figure 1.

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

been published as WSP 1313. That report contains a summary of monthly and annual discharges for all previously published records as well as some records not contained in the 

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

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

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

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

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

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

special reports also contain other pertinent hydrologic information and analyses and 

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

numbers and titles of these reports.

WSP 147.......... Destructive floods in the United States in 1904.

WSP 162.......... Destructive floods in the United States in 1905.

WSP 771.......... Floods in the United States, magnitude and frequency.

WSP 847.......... Maximum discharges at stream-measurement stations through

	September 1938. 

WSP 967-A........ Floods of September 1939 in Colorado River basin below

	Boulder (Hoover) Dam. 

WSP 994.. ........ Cloudburst floods in Utah, 1850 to 1938.

WSP 997.......... Floods in Colorado.

WSP 1260-E....... Floods of April-June 1952 in Utah and Nevada.

WSP 1260-F....... Summary of floods in the United States during 1952.

WSP 1320-E....... Summary of floods in the United States during 1953.

WSP 1370-C....... Summary of floods in the United States during 1954.

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

Streamflow was generally near median the first 6 months of the water year and generally 

deficient the last 6 months. Deficient streamflow existed in practically every month of 

the water year in some part of the area covered by this report. Little Colorado River 

near Cameron, Ariz., and Rillito Creek near Tucson, Ariz., were dry all of July. This is 

only the 4th time that this has occurred in July on the Little Colorado River since 1921 

and the 5th time that it has occurred on Rillito Creek in 52 years of record. Little 

Colorado River near Cameron remained dry all of August whicn is the first time that this 

has happened in 40 years. Record low daily flow for September occurred in Gila River above 

Safford Valley, Ariz. In Arizona, record high daily flow occurred on Salt River near Roosevelt and Verde River below Tangle Creek, above Horseshoe Dam during October and on Little 

Colorado River near Cameron during November and December. Cloudburst flood near Tabiona, 

Utah on Sept. 2 developed rates of streamflow exceeding 500 cubic feet per second per 

square mile from 8.1 square miles.

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 1960 water year with 

the median discharge for the period 1931-60.

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, 290 cfs June 17 (gage height, 2.59 ft); no flow 

Aug. 9-11.

1933-60: 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, 1960.

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 

unknown for 1960 water year.

ERASER RIVER BASIN 27

325. Ranch Creek near Tabernash, Colo.

Location. Lat 39°59'51", long 105°49'22", In NE^NW^ sec. 6, T.I S.. R.75 W. , on right bank 

a quarter of a mile upstream from Meadow Creek and 1.2 miles east of Tabernash.

Drainage area. 50.7 sq mi.

Records available . September 1934 to September 1960 (discontinued). Records since 

May 15, 1949, equivalent to earlier records if diversion to Moffat water turnel is 

added to flow past station.

~Gage. Water-stage recorder. Datum of gage is 8.339.79 ft above mean sea level, datum of 

Average discharge . 26 years, 40.5 cfs (29,320 acre-ft per year), including diversion to 

Moffat water tunnel .

Extremes Maximum discharge during year, 402 cfs June 6 (gage height, 3.76 ft); maximum 

gage height, 5.63 ft Mar. 25 (backwater from ice); minimum discharge not determined.

1934-60: Maximum discharge, 754 cfs June 29, 1957 (gage height, 5.01 ft); maximum 

gage height, that of Mar. 25, 1960; no flow Feb. 15 to Mar. 13, 1937, Feb. 13, 1947, 

and perhaps other days.

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

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

6,950 acre-ft during water year 1960. Small diversion to Fraser River basin and several small diversions for irrigation of about 300 acres of hay meadows above station.

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

Average discharge. 9 years, 1,614 cfs (1,168,000 acre-ft per year).

Extremes. Maximum discharge during year, 8,200 cfs Mar. 26 (gage height, 5.35 ft); minimum daily, 330 cfs Mar. 1.

1951-60: Maximum discharge, 14,600 cfs May 29, 1956 (gage height, 7.42 ft); minimum 

daily, 170 cfs Nov. 16, 1955.

Maximum discharge observed, 22,200 cfs June 19, 1918, at site 1-J miles upstream. 

Revisions. The figure of maximum discharge for the water year 1957 has been revised 

to 13,400 cfs June 11, 1957 (gage height, 7.01 ft), superseding that published in 

WSP 1513.

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

which are poor. Natural flow of stream affected by transmountain diversions, storage 

reservoirs, power developments, diversions for irrigation, and return flow from irrigated areas. Records of chemical analyses, suspended sediment loadSj and water temperatures for the water year 1960 are given in WSP 1744.

Revisions. Revised figures of discharge, in cubic feet per second, for the water year 

1957, superseding those published in WSP 1513, are given herewith:

September I960. 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 l| miles downstream at different daturas. 

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

of a mile downstream at different daturas. Nov. 14, 1917, to Sept. 30, 1942, waterstage recorder at present site at datum 4.34ft lower. Oct. 1, 1942, to Aug. 5, I960, 

water-stage recorder at present site at datum 0.66 ft higher.

Average discharge. 47 years (1913-60), 102 cfs (73,840 acre-ft per year).

Extremes. Maximum discharge during year, 796 cfs May 12 (gage height, 2.13 ft); minimum 

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

1911-60: Maximum discharge, 2,050 cfs May 29, 1921, from rating curve extended 

above 860 cfs; maximum gage height, 3.39 ft June 16, 1929, present datum; minimum discharge recorded, 13 cfs Apr. 26, 1957, Feb. 6-19, Mar. 19, 20, 1960.

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. 229). 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.

2780. South Fork Rock Creek near Hanna, Utah

Location. Lat 40°33'10", long 110°42'10", in SE£ sec.20, T.2 N. , R.7 W. , Uinta meridian, 

on right bank 1 mile upstream from mouth and 11 miles northeast of Hanna.

Drainage area. 14 sq mi, approximately.

Records available.--August 1953 to September 1960.

Gage. Water-stage recorder. Altitude of gage is 7,860 ft (from river-profile map).

Average discharge. 7 years, 11.2 cfs (8,110 acre-ft per year).

Extremes.--Maximum discharge during year, 59 cfs June 3 (gage height, 1.88 ft); maximum 

gage height, 2.91 ft Nov. 20 (backwater from ice); minimum discharge rot determined

1953-60: Maximum discharge, 139 cfs May 29, 1958 (gage height, 2.42 ft); maximum 

gage height, that of Nov. 20, 1959; minimum discharge not determined.

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

which are fair. Pipeline that provides water for small hydroelectric plant and irrigation for Dude Ranch (capacity, approximately 1.5 cfs) diverts water from creek a 

short distance above station at times in summer months.

2970. Uinta River near Neola, Utah

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

on left bank 300 ft downstream from bridge , three-quarters of a mile upstream from Pole 

Creek, and 7 miles north of Neola.

Drainage area.--181 sq mi.

Records available.--July 1921 to September 1927 (no winter records 1922-25, 1927), September 1929 to September 1960.

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

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

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

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

Average discharge.--32 years (1925-26, 1929-60), 170 cfs (123,100 acre-ft per year).

Extremes. Maximum discharge during year, 1,070 cfs May 13 (gage height, 3.91 ft); minimum recorded, 42 cfs Mar. 11.

1929-60: 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, 5.5? 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 sTiall 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 I960, of Pole Creek canal are as follows:

flow for several days in July, August, September.

1909-11, 1945-60; Maximum discharge observed, 8,150 cfs Sept. 1, 1909 (gage height, 

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

many float measurements; no flow for several days in July, August, September 1910, 

July, August, September 1960.

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

which are fair. Discharge measurement or observation of no flow generally made once 

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

is above station. Flow affected by storage in Scofield Reservoir since 1926 (see 

p. 278). Records of chemical analyses for the water year 1960 are given in WSP 1744.

Records available.--January 1910 to September 1911, August 1927 to December 1931, November 

1955 to September 1960. Monthly discharge only for some periods, published in tfSP 1313.

Gage. Water-stage recorder. Altitude of gage is 5,405 ft (from river-profile map). 

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

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

Average discharge.--9 years (1910-11, 1927-31, 1956-60), 1,645 cfs (1,191,000 acre-ft per 

year).

Extremes.--Maximum discharge during year, 8,900 cfs Oct. 2 (gage height, 7.25 ft); maximum 

gage height, 7.32 ft Mar. 27; minimum daily discharge, 196 cfs Aug. 20.

1910-11, 1927-31, 1955-60: Maximum discharge determined, 20,500 cfs July 27, 1957; 

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

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

Maximum flood known reached a stage of 12 ft Oct. 6, 1911, datum ther in use (discharge, 80,000 cfs, estimated). Another major flood occurred Sept. 6, 1909.

Remarks, Records fair except those for periods of ice effect or doubtful or no gageheight record, which are poor. Discharge measurements generally made 2 to 5 times a 

month. Diversions above station for irrigation of about 52,000 acres, 2,000 of which 

is below station. Records of suspended sediment loads and water temperatures for the 

water year 1960 are given in WSP 1744.

3650. San Juan River at Farmington, N. Mex.

Location.--Lat 36°43'25", long 108°13'30", in SE^ sec.17, T.29 N., R.13 W., on left bank 

360 ft downstream from highway bridge, 4,000 ft downstream from Animas River, and 1 mile 

west of Farmington.

Drainage area. 7.240 sq mi, approximately.

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

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

1912 to September 1960. Monthly discharge only for some periods, published in WSP 1313.

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

T929. June 19, 1904, to May 10, 1906, wire-weight gage at site li miles downstream at 

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

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

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

prior to October 1932, and 0.53 ft higher thereafter.

Average discharge. 48 years (1912-60), 2,594 cfs (1,878,000 acre-ft per year).

Extremes. Maximum discharge during year, 9,750 cfs June 5 (gage height, 4.98 ft); minimum daily, 249 cfs Aug. 21.

1912-60: Maximum discharge, about 68,000 cfs June 29, 1927 (gage height, 10.2 ft, 

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

27 cfs Aug. 28, 1939.

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

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

Remarks.--Records good except those for periods of ice effect or doubtful o" no gageheight record, which are poor. Discharge measurements generally made 2 to 4 times a 

month. Diversions above station for irrigation of about 86,000 acres, 4,000 of which 

is irrigated by Farmers Mutual ditch (see table below) which diverts from Animas River 

and bypasses this station; ditch flow not included in record. At times this ditch may 

be supplied partly or entirely by diversion from San Juan River below this station.

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

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

Remarks. Records excellent except those for period of ice effect, which ere fair. Dis-

 cfiarge measurements generally made four 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 temperatures for the 

water year 1960 are given in WSP 1744.

336 PARIA RIVER BASIN

3820. Paria River at Lees Ferry, Ariz.

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

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

Drainage area. 1 : 570 sq mi, approximately. 

Records available. October 1923 to September 1960.

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

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

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

Average discharge.--37 years, 30.6 cfs (22,150 acre-ft per year); median of yearly mean 

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

Extremes.--Maximum discharge during year, 370 cfs June 7 (gage height, 7.67 ft); minimum 

daily, 2.6 cfs Jan. 3.

1923-60: Maximum discharge, 19,000 cfs Sept. 12, 1956 (gage height, 15.3 ft), from 

rating curve extended above 1,500 cfs on basis of peak discharge computed as difference 

of flow of Colorado River above and below Paria River; maximum gage height, 16.3 ft 

Oct. 5, 1925 (from floodmark); no flow for periods in several winters prior to 1928.

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

those for periods of ice effect, which are poor. Diversions above station for irrigation of about 3,300 acres. Records of suspended sediment loads and water temperatures 

for the water year 1960 are given in WSP 1744.

TRANSMOUNTAIN DIVERSIONS 337

Transmountain diversions from Colorado River basin above Compact 

point, near Lees Perry, Ariz.

Records of all the transmountain diversions from the Colorado River basin above 

Ccmpact point, near Lees Ferry (the division point between the upper and lower basins 

of the Colorado River Compact) are given herein. They are listed and tabulated separstely by States.

In Colorado there are 22 tunnels or ditches, 21 of which are equipped with water-stage 

recorders. Records furnished by State engineer. The locations of these diversions are 

given in the following list.

100. Grand River ditch diverts water from tributaries of Colorado River to La Poudre 

PESS Creek (tributary of Cache la Poudre River) in the Platte River basin. Two collection ditches from headgates in sec.28, T.5 N., R.76 W., and sec.29, T.6 N., R.75 W., 

irtercept all tributaries upstream on each side of the Colorado River and converge at 

LE Poudre Pass.

Revisions (water years).--WSP 1313: 1912-27.

120. Eureka ditch diverts water from tributaries of Tonahutu Creek between headgate 

in sec.7, T.4 N. , R.74 W., and Sprague Pass, to Spruce Creek (tributary of Big Thompson 

RJver) in the Platte River basin.

Revisions (water years). WSP 1313: 1949.

130. Alva B. Adams tunnel diverts water from Shadow Mountain Reservoir and Grand Lake, 

ir NW-f sec.9, T.3 N. , R.75 W. , to Lake Estes (Big Thompson River) in the Platte River 

bssin. For daily discharge, see p. 15.

215. Berthoud Pass ditch diverts water from tributaries of Fraser River between the 

headgate, in sec.33, T.2 S., R.75 W., and Berthoud Pass, to Hoop Creek (tributary of West 

Fork Clear Creek) in the Platte River basin.

225. Moffat water tunnel diverts water from tributaries of Fraser River to South Boulder 

Creek in the Platte River basin by means of three collection ditches extending from the 

right bank of St. Louis Creek in sec.20, T.2 S., R.76 W., right bank of Vasquez Creek in 

sec.18, T.2 S., R.75 W., right bank of Fraser River in sec.23, T.2 S., R.75 W., left bank 

of North Fork Ranch Creek in sec.24, T.I S., R.75 W., and intercepting intermediate tributaries to the west portal of the tunnel. Since July 1959, water diverted by Jones Pass 

tunnel from tributaries of Williams Fork between the headgate on right bank of Bobtail 

Creek in sec.28, T.3 S., R.76 W., and headgate on left bank of McQueary Creek in sec.16, 

T.3 S., R.76 W., has been rediverted through Vasquez tunnel to Vasquez Creek in the Fraser 

River basin in sec.l, T.3 S., R.76 W., thence via collection ditch to the west portal of 

Moffat water tunnel where it is diverted to South Boulder Creek in the Platte River basin. 

(See table of diversions by Jones Pass tunnel published with records for Williams Fork 

near Leal, Colo.)

420. Hoosier Pass tunnel diverts water from tributaries of Blue River to Montgomery 

Reservoir (Middle Fork South Platte River), revised, in the South Platte River basin, 

from whence it is again diverted to South Catamount Creek, revised (tributary to 

Catamount Creek) in the Arkansas River basin. Three collection conduits, from Monte 

Cristo Creek in SWijNEir sec.2, T.8 S., R.78 W., Bemrose Creek in SWp3Wv sec.6 T.8 S., 

R.77 W., and McCullough Gulch in sec.26, T.7 S., R.78 W., intercept intermediate tributaries and converge at the north portal of the tunnel.

460. Boreas Pass ditch diverts water from tributaries of Blue River betweer the headgate in sec.S6, T.7 S. , R.77 W., and Boreas Pass, to Tarryall Creek in the Platte River 

basin.

485. Fremont Pass ditch diverts water from tributaries of Tenmile Creek in sees. 2 and 

3, T.8 S., R.79 W., to East Fork Arkansas River.

615. Columbine ditch diverts water from tributaries of Eagle River in sec.5, T.8 S. , 

R.79 W., to Chalk Creek (tributary of East Fork Arkansas River).

620. Ewing ditch diverts water from left bank of Piney Creek (tributary of Eagle River) 

in sec.11, T.8 S., R.80 W., to Thayer Gulch (tributary of Tennessee Creek), revised, in 

Arkansas River basin.

625. Wurtz ditch diverts water from tributaries of Eagle River between the headgate in 

sec.32, T.7 S. , R.80 W. , and Tennessee Pass, to Tennessee Creek (revised) in .Arkansas

LITTLE COLORADO RIVER BASIN

3855*. Little Colorado River below Lyman Reservoir, near St. Johns, Ariz.

Location. --Lat 34°22', long 109 °23', in SW^NEij sec.9, T.ll N. , R.28 E. , 65 ft downstream 

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

Drainage area.--790 sq mi.

Records available.--April 1941 to June 1954, April 1955 to September 1960.

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

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

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

Average discharge. 17 years (1941-53, 1955-60), 2.55 cfs (1,850 acre-ft per year).

Extremes.--Maximum daily discharge during year, 10 cfs July 3-5; minimum daily, 0.1 cfs 

for many days.

1641-60: Maximum discharge observed, 603 cfs May 8, 1941 (including 546 cfs of 

spilled water); no flow at times in most years.

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

 are~fair. Record of daily discharge shows all water spilled and released from Lyman 

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

(see preceding page). See monthly table for combined flow of river and canal. No flow 

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

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

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

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

about 8,200 acres, including 1,500 acres served by Lyman Canal. Flow past this station supplemented by spring inflow downstream used to irrigate an additional 2,000 

acres in vicinity of St. Johns.

3920. Show Low Creek below Jaques Dam, near Show Low, Ariz.

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

just below Jaques Dam, 3f miles northwest of Lakeside and 4? miles southeast of Show 

Low.

Drainage area. 67.2 sq mi.

Records available. November 1941 to January 1945, June 1953 to September 19F5 (monthly 

discharge only), October 1955 to September 1960. Monthly discharge only Fovember 1941 

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

Gage. Water-stage recorder and V-notch weir with supplementary lake elevation readings 

Tor flow over concrete spillway. Altitude of gage is about 6,530 ft (from topographic 

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

datum.

Average discharge. 7 years (1953-60), 3.V2 cfs (2,690 acre-ft per year).

Extremes. Maximum discharge during year. 440 cfs (inflow from spillway several hundred 

feet downstream from station) Mar. 8 (lake elevation, 6,570.80 ft from flcodmark), minimum daily discharge, 0.3 cfs Oct. 29 to Nov. 2.

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

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

1953-60: Maximum discharge, that of Mar. 8, 1960; no flow at times.

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

which are fair, and those for period of spill, which are poor. Record sirce 1953 shows 

flow below Lake Show Low in Show Low Creek. 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 Porestdale Creek diversions from Show Low Creek, near Show Low).

Revisions. WSP 1393: Drainage area.

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

Jaques Dam in NW^ sec.10, T.9 N., R.22 E., 4| miles southeast of Show Low; dam completed and storage began in spring of 1953. Total capacity to spillway, 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 ard 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. Elevations obtained periodically by Navapache 

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

LITTLE COLORADO RIVER BASIN 353

3970. Little Colorado River at Holbrook, Ariz.

Location.--Lat 34°53'50", long 110°09i40", in SW^-SW^ sec.6, T.17 N., R.21 E., near right 

bank on downstream side of bridge on U. S. Highway 260 at Holbrook, 2-j 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 1960.

Average discharge.--13 years (1905-6, 1949-60), 96.7 cfs (70,010 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, 11,400 cfs Oct. 29 (gage height, 9.50 ft); 

minimum, 0.1 cfs May 30.

1905-9, 1949-60: Maximum discharge determined, 21,800 cfs Aug. 5, 1957 (gage 

height, 10.96 ft); maximum daily, 20,200 cfs Nov. 27, 1905; no flow at times in most 

summers.

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

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

was probably the greatest flood since 1870.

Remarks. Records fair except those for periods of ice effect or doubtful or no gageheight record, which are poor. Diversions above station for irrigation of about 

23.000 acres. Some regulation by reservoirs (combined capacity, about 7J.OOO acreft).

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

COLORADO RIVER MAIN STEM 

4025. Colorado River near Grand Canyon, Arlz.

363

Location. Lat 36°Q5'55", long 112°05'30", on left bank at Kalbab 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 1960. Prior to 1944, published as Colorado 

River at Bright Angel Creek, near Grand Canyon. Gage-height records collected 1^ miles 

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

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

and 1 on right bank 700 ft downstream since Dec. 9, 1922, used only for high water 

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

of 1929.

Average discharge.--38 years, 17,010 cfs (12,310,000 acre-ft per year).

Extremes. Maximum discharge during year, 46,300 cfs June 10 (gage height, 17.95 ft); minimum, 2,710 cfs Aug. 25 (gage height, 1.26 ft).

1922-60: Maximum discharge, 127,000 cfs July 2, 1927 (gage height, 29.25 ft); minimum, 700 cfs Dec. 28, 1924 (gage height, -0.70 ft).

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

studies at Lees Ferry). Crest discharge of flood of June 19, 1921, 220,(no cfs (gage 

height, 37.5 ft, from floodmarks), from rating curve extended above 120, 010 cfs by logarithmic plotting.

Remarks. Records excellent except those for period of doubtful gage-height record, which 

are good. Discharge measurements generally made once a week; more often during high 

water. Natural flow of stream affected by transmountain diversions, storage reservoirs, 

power developments, ground-water withdrawals and diversions for irrigation, and return 

flow from irrigated areas. Records of chemical analyses, suspended sedimsnt loads, and 

water temperatures for water year 1960 are given in WSP 1744.

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

Average discharge. 37 years, 36.6 cfs (26,500 acre-ft per year).

Extremes.--Maximum discharge during year, 240 cfs June 6 (gage height, 1.52 ft); minimum 

daily, 14 cfs for several days.

1923-60: Maximum discharge, 4,400 cfs Aug. 19, 1936, from rating curve extended 

above 250 cfs on basis of slope-area measurement of peak flow; minimum daily, 12 cfs 

July 3-14, 1959.

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

which are fair. Minor diversion for irrigation of a few acres above station. Some 

fluctuation in flow caused by powerplant 9 miles upstream from station; no regulation 

by storage. Records of chemical analyses for the water year 1960 are given in WSP 1744.

384 COLORADO RIVER MAIM STEM

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 sqmi, approximately.

Records available. January 1917 to September 1960. Daily mean elevations published 

since October 1938.

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

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

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

supplementary 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), 2U.260 cfs (14,670,000 acre-ft per year); 26 years 

(1934-60), 14,070 cfs (10,160,000 acre-ft per year), unadjusted.

Extremes.--Maximum discharge during year, 17,700 cfs July 1; maximum elevation, 457.21 

ft July 1; minimum discharge, 6,900 cfs Dec. 20; minimum elevation, 452.32 ft Dec. 20.

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

1,480 cfs Aug. 17, 1934.

1934-60: Maximum discharge, 35,700 cfs Jan. 29, 1942; maximum elevation, 457.37ft, 

July 9, 1959; minimum discharge, 375 cfs Feb. 14, 1935; minimum daily, 42S 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 1857-63 and most likely in 1862.

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

diversions above station for irrigation, municipal, and industrial uses. Flow regulated by Lake Mead (see p. 379) since Feb. 1, 1935, and by Lake Mohave (see p. 381) 

since Jan. 17, 1950. Records of water temperatures for the water year 1960 are given 

in WSP 1744.

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

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 1960 (monthly diversions only after October 1942).Published as a supplement to records for Colorado River belcw Parker Dam, 

1942-50.

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

Average discharge.--21 years, 360 cfs [260,600 acre-ft per year).

Extremes. 1939-60: Maximum daily diversion, 1,990 cfs Aug. 14, 1960; no diversion at

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

from Havasu Lake. During the year 7,778 acre-ft (partly estimated) of cooling water, 

which is included in the record of diversions, was returned to Havasu La're at the 

pumping plant. Percolation from Gene and Copper Basin Reservoirs was measured in 

4 washes between pumping plant and Copper Basin Wash by means of weirs, each about 

1 mile from Colorado River. Percolation amounted to 5,124 acre-ft during the water 

year and was not subtracted from the diversion record.

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

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 1960. 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, 608,000 acre-ft May 12 (elevation, 449.97 ft); 

minimum, 520,200 acre-ft Mar. 23 (elevation, 445.29 ft).

1938-60: 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, 

TS31T. Usable capacity, 619,400 acre-ft between elevations 400.54 (sill of regulating 

gates) and 450.54ft (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 0.07 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, reregulation of river for irrigation demand, and as a basin from which water is pumped by Metropolitan Water District 

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

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

COLORADO RIVER MAIN STEM 391

4280. Colorado River below Parker Dam, Ariz.-Calif.

Location.--Lat 34°15'30", long 114°09'00", in NE^SW^- sec.16, T.2 N., R.27 E., San Bernardino meridian, on right bank 3.9 miles downstream from Parker Dam, 10.4 miles 

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

Drainage area. 178.800 sq mi, approximately.

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

records), October 1934 to September 1960. Published as "near Parker Ariz." prior 

to October 1937.

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

1929.

Average discharge.--26 years (1934-60), 13,710 cfs (9,926,000 acre-ft per year), unadjusted; 13,740 cfs (9,947,000 acre-ft per year), adjusted for storage in Havasu Lake 

but not Lake Mead and Lake Mohave.

Extremes.--Maximum discharge during year, 18,700 cfs June 11 (gage height 21.62 ft)- 

minimum, 3,500 cfs Dec. 5 (gage height, 17.40 ft).

1934-60: Maximum discharge, 42,400 cfs Feb. 8, 1937; no flow at Parker Dam for 

parts of several days in 1942 when gates in dam were closed; minimum daily 1 440 cfs 

Feb. 15, 1935.

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

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

Remarks.--Records excellent. Discharge measurements generally made twice a month. Many 

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

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

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

392 TRIBUTARIES AND DIVERSIONS BETWEEN PARKER DAM AND PALO VERDE DIM

4285. Colorado River Indian Reservation Main Canal, near Parker, Ariz.

Location. Two gages, lat 34°10'05", long 114°16'30", in SE^NW-jj sec.31, T.10 N. , R.19 W. , 

Gila and Salt River meridian. Forebay gage, in river gate-control structure at Arizona 

end of Headgate Rock Dam. Tailrace gage, 250 ft below canal intake gates at Headgate 

Rock Dam. Both gages are on Colorado River Indian Reservation Ij miles northeast of 

Parker and 14-jy miles downstream from Parker Dam.

Records available.--January 1915 to September 1960 (prior to January 1937, fiscal year 

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

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

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

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

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

Prior to October 1954, discharge computed by various methods as described in WSP 1313.

Extremes.--Maximum daily diversion during year, 988 cfs July 17, 18; no diversion Jan. 30

1955-60: Maximum daily diversion, that of July 17, 18, 1960; no diversion at times 

in most years.

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

computed on basis of head on intake gates and gate openings. Records show water 

diverted to project and surface return flows to Colorado River through 2 drainage 

canals and 2 wasteways, all of which are equipped with water-stage recorders. Water

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

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

less that of 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,

extends from a point about 8 miles east of State line to vicinity of Guthrie, Ariz. 

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

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

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

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

from station on Gila River below Blue Creek, near Virden, N. Mex. Intal-e of York 

Canal, at western end, is about 14 miles upstream from station on Gfila Fiver near 

Clifton, Ariz.

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 pumps for pumped

water.

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

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

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

Drainage area. 377 sq mi.

Records available . August 1944 to September 1960.

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

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

Average discharge . --16 years, 23.0 cfs (16,650 acre-ft per year), unadjusted; median of 

yearly mean discharges, 19 cfs (13,800 acre-ft per year).

Extremes . --Maximum discharge during year, 4,990 cfs Jan. 12 (gage height, 6.2 ft), from 

rating curve extended above 190 cfs on basis of hydraulic radius-velocity study; minimum daily discharge, 4.6 cfs Oct. 17, 18.

1944-60: Maximum discharge, 7,270 cfs Sept. 10, 1958 (gage height, 8.7 ft), from 

rating curve extended above 1,000 cfs on basis of slope-area measuremert of peak flow; 

minimum, 1.5 cfs Sept. 5, 1951.

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

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

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

Eagle Creek basin 25 miles upstream and since Apr. 27, 1959, from Eagle Creek Wells 

into Eagle Creek 1? miles upstream is an appreciable part of flow past this station 

(see p. 407 for diversions from Black River). Water pumped from Eagle Creek Wells 

is shown below in monthly summary.

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

and 13 miles upstream from mouth.

Drainage area. 613 sq mi.

Records available.--April 1944 to September 1960.

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.--16 years, 35.0 cfs (25,340 acre-ft per year), unadjusted; median of 

yearly mean discharges, 29 cfs (21,000 acre-ft per year).

Extremes. Maximum discharge during year, 5,350 cfs Jan. 12 (gage height, 7.6 ft, at supplementary gage); minimum, 7.9 cfs July 2.

1944-60: 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| mileles downstream.

Remarks. Records good except those above 50 cfs, which are fair. Diversions above statflon for irrigation of about 500 acres, mostly above Willow Creek. Water from Black 

River was pumped into Eagle Creek basin, 51? miles upstream from this station, for 

about 6 months (see p. 407); 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, 2| miles downstream from this station, and from San Francisco River near Clifton. 

The monthly quantities diverted are shown in the table below. Ninety-four percent of 

the pumpage was from Eagle Creek.

4695. Gila River below Coolidge Dam, Ariz.

Location. Lat 33°10'15", long 110°31'45", in SW^ sec.17, T.3 S., R.18 E. (ursurveyed), 

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

Drainage area. 12,886 sq mi.

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). 48 years (1900-1901, 

1903-4, 1914-60), 359 cfs (259,900 acre-ft per year); median of yearly mean discharges, 

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

Extremes.--Maximum discharge during year, 861 cfs July 20 (gage height, 3.43 ft); minimum daily, 2.4 cfs Nov. 25-30, Dec. 2.

1914-60: Maximum discharge, 130,000 cfs Jan. 20, 1916, estimated on basis of peak 

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

Maximum discharge since completion of Coolidge Dam, 1,350 cfs July 28, 1952 (gage 

height, 4.64 ft).

Remarks. Records excellent except those below 5 cfs, which are fair. Large diversions 

above San Carlos Reservoir for irrigation, metallurgical treatment of ore, and municipal supply. About 55,500 acres of land was irrigated, a considerable portion by 

pumping from ground water. Plow regulated by San Carlos Reservoir at Coolidge Dam 

since Nov. 15, 1928 (see preceding page). Record includes flow of Warm Springs which 

enters between dam and gage and was measured during the 1960 water year as 0.64 cfs 

Jan. 21.

GILA RIVER BASIN

4700. Gila River at Winkelman, Ariz.

Location. Lat 33 "00'10", long 110°45'55", in NW^NE^ sec. 13, T.5 S. , R.15 E., on right 

bank ! $ miles north of Winkelman, 2 miles upstream from San Pedro River, and 29 miles 

downstream from Coolidge Dam.

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

Records available. September 1917 to June 1918, December 1928 to February 1935 (discharge 

measurements only), September 1941 to September 1960.

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

1929, supplementary adjustment of 1949. Sept. 10, 1917, to June 1918, chain gage at

bridge 1.5 miles downstream at different datum.

Average discharge (adjusted for storage in San Carlos Reservoir). 19 years (1941-60), 

189 cfs (136,800 acre-ft per year); median of yearly mean discharges, 150 cfs (109,000 

acre-ft per year).

Extremes. Maximum discharge during year, 2,370 cfs Dec. 26 (gage height, 7.44 ft); minimum, 7.8 cfs Dec. 2.

1941-60: 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 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, metallurgical treatment of ore, and muncipal 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. 418).

GILA RIVER BASIN 425

4740. Gila River at Kelvin, Ariz.

Location.--Lat 33°06'10", long 110°58 I 45", in NWjj-NWij sec.12, T.4 S., R.13 E. , on left bank 

at Kelvin, 1,000 ffc downstream from Mineral Creek, 17 miles downstream from San Pedro 

River, and 192 miles upstream from Ashurst-Hayden Dam.

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

Records available. January 1911 to September 1960.

Gage. Water-stage recorder. Supplementary water-stage recorder 900 ft upstream since

lay 27, 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 de-turns.

Average discharge (adjusted for storage in San Carlos Reservoir).--49 years, <*85 cfs

(352,100 acre-ft per year); median of yearly mean discharges, 350 cfs (254,000 acre-ft 

per year).

Extremes.--Maximum discharge during year, 11,200 cfs Dec. 26; maximum gage height, 11.22 ft 

Sept. 9; minimum daily discharge, 27 cfs Nov. 18, Dec. 4, 5.

1911-60: Maximum discharge, about 132,000 cfs Jan. 20, 1916 (gage heigtt, 19.5 ft), 

from rating curve extended above slope-area measurement at gage height 16. £ 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 diversiors above 

station for irrigation, of which about 90 percent is above Coolidge Dam. About 78,000 

acres irrigated (in 1955), a considerable portion by pumping from ground wster. Plow 

regulated by San Carlos Reservoir (Coolidge Dam) after Nov. 15, 1928 (see F. 418 ); no 

other regulation. San Pedro River contributes major portion of unregulated inflow. 

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

water year 1960 are given in WSP 1744.

Revisions (water years).--WSP 329: 1911. WSP 609: 1916(M). WSP 629: 1914-17. WSP 1119: 

1913, 1915, 1917(M), 1921(M), 1922-23, 1927(M). WSP 1283: Drainage area.

426 GILA RIVER BASIN

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 1960 (head on crest of dam only). Records of 

monthly diversions to Florence-Casa Grande Canal, January 1928 to September 1960.

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

cfatum of 1929. Crest elevation normally raised 1.0 ft to 1.4 ft 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, 3.05 ft Dec. 26; no flow over dam most of year. 

1923-60; Maximum head on dam, 3.0 ft Sept. 28, 1926; no flow over dam most of each 

year.

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

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

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

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

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

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

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

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

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

Average discharge.--17 years (1939-46, 1950-60), 28.1 cfs (20,300 acre-ft per year); 

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

Extremes.--Maximum discharge during year, 6,420 cfs Aug. 11 (gage height, 6.12 ft); no 

flow for most of year.

1939-47, 1950-60: Maximum discharge, 17,000 cfs Aug. 14, 1940 (gage height, 9.9ft, 

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

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

which are poor. Many diversions above station, mostly by pumping from ground water, 

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

disposal plant occasionally causes flow past station during dry.periods, but is not 

included in this record.

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 upstres-m 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 1960.

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

1929, Phoenix-Picacho supplementary adjustment of 1949.

Average discharge. 18 years (1940-46, 1948-60), 21.7 cfs (15,710 acre-ft per year); 

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

Extremes. Maximum discharge during year, 707 cfs Jan. 15 (gage height, 11.97 ft); no 

flow for many days.

1940-46, 1947-60: 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 fair. Many diversions above station, mostly by pumping from 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.

Extremes. Maximum discharge during year, 78,200 cfs Dec. 26 (gage height, 2f..30 ft): minimum, 106 cfs Sept. 27, 28.

1913-60: Maximum discharge, 117,000 cfs Mar. 14, 1941 (gage height, 2*.4 ft), from 

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

measurements at 66,000 and 102,000 cfs; minimum, 59 cfs all or part of each day 

July 1-4, 7-12, 1955.

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

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

Several small diversions for irrigation of about 4,000 acres above station and 2 transbasin diversions above station, 1 into basin from Show Low Creek and 1 out of basin to 

Willow Creek. Discharge measurements generally made 3 or 4 times a month. Records 

show inflow to Roosevelt Reservoir. See page 464 for record for Tonto Creek, which 

also contributes to Roosevelt Reservoir. Records of water temperatures for the water 

year 1960 are given in WSP 1744.

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

465

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

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

Apache Lake, formed by Horse Mesa Dam, 17 miles downstream from Roosevelt Dam; Canyon 

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

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

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

Records available April 1910 to September 1960. Prior to October 1934 month-end contents only, published in WSP 1313. Evaporation: April 1958 to September 1960.

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, 1,452 000 acre-ft May 20- minimum 

503,600 acre-ft Oct. 28. ' '

1910-60: Maximum contents, 1,764,000 acre-ft May 22, 1941; minimum 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 (sill of lowest outlet in Stewart Mountain Dam) to 2,136 ft (top of spillway 

gates in raised position on Roosevelt Dam). Since 1910, spill over Roosevelt Dam 

because of capacity storage has occurred only during the following periods- Apr. 15 

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

1920, and Apr. 13 to July 24, 1941. Water from this system is used for irrigation of 

Salt River Valley and for generation of power.

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

Association.

Revisions.--WSP 1283: Drainage area.

GILA RIVER BASIN 

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

Location. Lat 34°22'05", long 111 0 39'55", in NE-jjSWjj sec. 20, T.llj N., R.7 E., at head of 

Stehr Lake , 2£ miles northeast of Childs powerplant, 4.4 miles by flume downstream from 

Irving powerplant, and 17? miles southeast of Camp Verde.

Records available . --January 1952 to September 1960.

Gage. Water-stage recorder and weir in concrete flume, 

(from topographic map).

Altitude of gage is 3,730 ft

Extremes.--1952-60; Maximum daily discharge, 51 cfs Apr. 17-21, 1952; no flow for short 

periods in most years.

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

which are fair. Record is obtained at head of Stehr Lake, a regulatory basin, and 

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

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

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

Fossil Creek enters the flume below Irving powerplant and was measured as follows-. 

Nov. 13, 0.96 cfsj July 15, 0.11 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.

Discharge, in cubic feet per second, water year October 1959 to Septembej 1960

Extremes.--Maximum discharge during year, 23,400 cfs Dec. 26 (gage height, 14.57 ft); minimum"!" 61 cfs July 18, caused by power regulation on Fossil Creek.

1945-60: Maximum discharge, 81,600 cfs Dec. 31, 1951 (gage height, 17.62 ft), from 

rating curve extended above 42,000 cfs by logarithmic plotting; minimum, 48 cfs June 17, 

1956, July 18, 19, 1958, caused by power regulation on Fossil Creek.

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

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

on Verde River.

Remarks.--Records good prior to April and excellent thereafter except those for periods of 

fragmentary or no gage-height record, which are fair. Discharge measurements generally 

made twice a month. Diversions above station for irrigation of about 12,500 acres, 

some of which is pumping from ground water. Low flow slightly regulated by powerplant 

32 miles above station, using water from Fossil Creek. This station is above all major 

reservoirs on Verde River.

5095. Reservoir system on Verde River at and below Horseshoe Dam, A^lz.

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. (unsarveyed).

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

Records available .--July 1939 to September 1960. Prior to 1946, published a<3 Bartlett 

Reservoir at Bartlett Dam.

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

17900.00 ft and on Bartlett Reservoir 1,609.46 ft above mean sea level, datum of 1929.

Extremes.--Maximum contents during year, 260,400 acre-ft Mar. 11; minimum, 18,700 acre-ft

1939-60: 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, 1954. Bartlett Reservoir is formed by concrete multiple-arch 

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

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

between elevations 1,915.0 (sill of outlet gate) and 2,026.0 ft (top of spillway gates); 

Bartlett Reservoir, 179,500 acre-ft between elevations 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 

and for municipal supply.

5100. Verde River below Bartlett Dam, Ariz.

Location. Lat 33°48'30", long 111"40"00", in HE^ sec.6, T.5 N., R.7 E., on right bank 

2i miles downstream from Bartlett Dam and 3? miles upstream from Camp Creek.

Drainage area. 6,188 sq mi.

Records available.--August 1888 to September 1960. Prior to October 1941, published 

under different names as follows: "near Port McDowell," "at mouth," "above Salt 

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

Creek, neap McDowell."

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

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

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

Average discharge. 72 years, 685 cfs (495,900 acre-ft per year); median of yearly mean 

discharges, 550 cfs (398,000 acre-ft pep year), adjusted for storage in Bartlett and 

Horseshoe Reservoirs.

Extremes. Maximum discharge during year, 3,500 cfs July 4 (gage height, 8.20 ft); minimum daily discharge, 0.3 cfs Oct. 12, 14.

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

1891); minimum daily, 29 cfs July 11, 13, 1901. Floods of Nov. 27, 190F, and Mar. 4, 

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

1939-60: Maximum discharge, 45,800 cfs Mar. 15, 1941 (gage height, 17.5 ft, present site and datum, from floodmarks); no flow at Bartlett Dam at times in several 

years when gates in dam were closed.

Remarks. Records good. Discharge measurements generally made three or more times a 

month. Diversions for irrigation above station of about 12,500 acres, some of which 

is by pumping from ground water. Flow completely regulated by Bartlett Reservoir 

since Feb. 5, 1939, and Horseshoe Reservoir since Nov. 15, 1945 (see preceding page), 

except during periods of spill or occasional flood flow below Bartlett I'm. Entire 

flow is diverted at Granite Reef Dam, 10 miles downstream, for irrigation in Salt 

River Valley and municipal use by the City of Phoenix. Records of chemical analyses 

and water temperatures for the water year 1960 are given in WSP 1744.

Remarks. Water is diverted from infiltration galleries and shallow wells from the Verde 

River and also by pumping directly from the Verde and Salt Rivers. Infiltration galleries on right bank of Verde River in SE£ sec.6, T.3 N., R.7 E., three-quarters of a 

mile downstream from McDowell and 6^ miles upstream from mouth of river; pump on Verde 

River since 1950 located in SE^ sec.31, T.3 N., R.7 E., 1 mile upstream from mouth and 

6 miles downstream from McDowell; and four pumps on Salt River since May 6, 1954, 

located in SE£ sec.6, T.2 N., R.7 E., just below mouth of the Verde River. Water is 

used for municipal supply of Phoenix and is carried 29 miles to that cit/ by pipeline. 

Negligible amount of waste occurs below point of measurement.

Water for Phoenix municipal use since June 3, 1954, is also diverted from the Arizona Canal at the Squaw Peak filtration plant at lat 33°31', long 112°02', in SE£ 

sec.10, T.2 N., R.3 E. This water is included in published record Diversions from Salt 

River at Granite Reef Dam, Ariz. The diversion from Squaw Peak filtration plant is 

shown in the first table below.

5120. Diversions from Salt River at Granite Reef Dam, Ariz.

Location. --Lat 33°31', long 111°42', at heads of Arizona and South Canals, vihich divert 

on right and left banks, respectively, at Granite Reef Dam on Salt River, 3j miles downstream from Verde River.

Gages.--Water-stage recorders.

Remarks.--Records given herein are those of discharge at the two gaging stations less flow 

returned from the canals to the river by wasteways between stations and irrigated lands 

and represent the flow diverted from Salt River for irrigation in Salt River Valley and 

to city of Phoenix for municipal use. See preceding page for published record of Diversions for city of Phoenix from Salt and Verde Rivers near McDowell, Ariz. Discharge 

computed on basis of gage heights and current-meter measurements; flow returned to 

river at canal wasteways computed from records of rated gates or weirs. Plow at Granite Reef Dam is regulated by four dams on Salt River (see Reservoir System on Salt 

River at and below Roosevelt Dam), and by Bartlett and Horseshoe Dams on Verde River.

Cooperation. Records furnished by Salt River Valley Water Users' Associaticn.

daily, 0.1 cfs for many days.

1940-60: Maximum discharge, 13,000 cfs Mar. 1, 1941, from rating curve extended 

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

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

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

seepage only.

Remarks. Records fair except those for periods of indefinite stage-discharge relation or 

doubtful or no gage-height record, which are poor. Diversions above station for mining 

and irrigation of about 600 acres. No water diverted to Perry Canal this year.

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

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

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

Lake Pleasant Dam, at different datum.

Average discharge.--32 years (1914-19, 1933-60), 90.1 cfs (65,230 acre-ft per year); 

median of yearly mean discharges, 43 cfs (31,100 acre-ft per year).

Extremes. 1910-24. 1933-60: 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 poor. Figures given herein represent flow into Lake Pleasant. Discharge computed on basis of three factors as follows: 1. Change in contents of Lake 

Pleasant and in contents of small reservoir behind diversion dam ! £ 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 hydrograph. Weir rule 

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

from Lake Pleasant as measured over diversion dam (none since May 13, 1941). 3. Effect 

of rainfall and evaporation on lake; evaporation assumed as 0.85 of that measured once 

daily in 3-foot square land pan buried 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.

5135. Lake Pleasant at Lake Pleasant Dam, Ariz.

Location Lat 33"SI 1 , long 112"16', in NW£ sec.21, T.6 N. , R.I E. , at left upstream end 

of Lake Pleasant Dam on Agua Fria River.

Drainage area.--1,460 sq mi, approximately.

Records available.--February 1928 to September 1960 (annual figures only prior to 1939).

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, 49,710 acre-ft Mar. 25, 26, 27 (gage height,

 125.17 ft); minimum, 14,050 acre-ft Oct. 28.

1928-60: 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 aere-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.

Cooperation. Gage-height record furnished by Maricopa County Municipal Water Conservation

0.3 mile downstream from canal intake, 0.7 mile downstream from Agua Fria River, 

3 miles southwest of Avondale, and 4 miles downstream from Salt River.

Records available.--May 1953 to September 1960.

Gage. Water-stage recorder and Parshall flume. Datum of gage is 904.62 ft above mean 

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

Average discharge. 7 years, 28.9 cfs (20,920 acre-ft per year).

Extremes. 1953-60: Maximum daily discharge, 257 cfs Aug. 8, 1954; no flov for several 

days in most years.

Remarks.--Records good. Canal diverts from right bank of Gila River in SE^SW^- sec.28, 

T.I N., R.I W., for Irrigation in the Buckeye area. Total acreage this year in the 

Buckeye Irrigation District Is 17,700 acres. Record includes waste water and flow from 

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

channel In SW^NW^ sec.34, T.I N., R.I W., near mouth of Agua Fria River. In February 

1960 pumpage of water from the Buckeye Canal began between canal intake and measuring 

flume and Is not Included In the canal record.

482 GILA RIVER BASIN

5195. Gila River below Glllespie 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 Gillesple 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 1960 (river below dam only). Records for

Gila Bend Canal May 1935 to September 1960 (since October 1941, monthly t? is charge only); 

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

estimates only), October 1939 to September 1960 (since October 1941, monthly discharge 

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

September 1960. 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 

BTlow 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 erd 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 downstream 

from intake.

Average discharge (river below dam). 19 years (1941-60) 26.7 cfs (19,330 e ere-ft per 

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

Extremes. Maximum discharge over dam during year, 640 cfs Jan. 19 (gage height, 10.31 ft); 

no flow for most of year.

1921-60: Maximum discharge observed, 85,000 cfs Dec. 28, 1923 (gage feight, 16.0ft, 

present datum); no flow for most of time in most years.

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

Remarks. Records good except those below 10 cfs, which are fair. Records include flow 

over crest and through sluice gates of Gillespie Dam, but do not include flow in Gila 

Bend and Enterprise Canals which divert from river immediately above dam. Other large 

diversions above station for irrigation, 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; there was excessive flow from 

Nov. 4 to Dec. 10 which was estimated and included for this water year.

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 on following page. Records of combined flow are good. Records of chemical analyses and water 

temperatures for the water year 1960 are given in WSP 1744.

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

5210. Colorado River at Yuma, Ariz.

Location. Lat 32 0 43'45", long 114°37'15", in NW^NE^ sec.35, T.16 S., R.22 E., San Ber-

 nardino meridian, on left bank 500 ft upstream from lower highway bridge, 1,800 ft 

downstream from upper highway bridge at Yuma, half a mile upstream from Yuma Main 

Canal wasteway, 5 miles downstream from Gila River, 7 miles upstream from boundary 

between California and Mexico, and 19 miles downstream from Imperial Dam.

Drainage area. 242,900 sq mi, approximately, including all closed basins entirely within, 

the drainage boundary.

Records available. January 1878 to December 1901 (gage heights only), January 1902 to 

September I960.

Gage. Water-stage recorder. Datum of gage is 102.32 ft above mean sea level, Yuma proj-

 ect datum,or 102.86 ft, datum of 1929, leveling of 1941 (datum was 0.07 ft lower prior 

to earthquake of May 18, 1940). Prior to May 1922 staff gages at several sites 600 to 

1,000 ft upstream at approximately same datum. May 1922 to October 1933, water-stage 

recorder or automatic transmitter at site 800 ft upstream from present site at same 

datum. Nov. 11, 1933, to July 19, 1934, staff gage at present site and datum. Supplementary water-stage recorder 180 ft downstream since Oct. 30, 1953.

Extremes. Maximum discharge during year, 10,300 cfs Jan. 19 (gage height, 14.49 ft); min-

 imum daily, 377 cfs Feb. 26; minimum gage height, 10.55ft Jan. 5.

1902-34: Maximum discharge, 250,000 cfs Jan. 22, 1916 (gage height, 34.0 ft); minimum daily, 18 cfs Aug. 25-27, 1934, caused by diversion at Laguna Dam.

1934-60: Maximum discharge, 34,900 cfs Sept. 7, 1939 (gage height, 24.57 ft); minimum, 41 cfs Mar. 8, 1956; minimum gage height, 8.36 ft July 16, 1947. 

Remarks. Records excellent. Discharge measurements generally made once or twice a week.

 Many diversions from Colorado River and tributaries. Principal diversions below Parker 

Dam are Colorado River Indian Reservation Canal, Palo Verde Canal, All-Araerican 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 Reservation Canal Main Drain No. 4. Flow 

of Colorado River regulated by Hoover, Davis, Parker, Headgate Rock, and to a small 

extent by Imperial, Palo Verde, and Laguna Dams. No regulation on Oila R'ver below 

Painted Rock Dam. Records of chemical analyses for the water year 1960 are given in 

WSP 1744.

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

Location. Lat 32°46'35", long 114°38 I 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 

All-American Canal to Yuma Main Canal, 4 miles north of Yuma, and 14-J- miles downstream 

from intake of All-American Canal at Imperial Dam.

Records available. July 1926 to September 1960. Monthly discharge only prior to October 

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

above siphon-drop powerplant, October 1947 to September 1960 (monthly discharge only). 

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

wasteway, October 1940 to September 1960 (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.--34 years 1,713 cfs (1,240,000 acre-ft per year).

Extremes.--1930-60: 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 througl turbines, compuTed from relation between discharge, head, and gate openings as logged by powerplant 

operators. Bypass discharge through waste gates determined from relationship of forebay elevation and gate openings as logged by powerplant operators. Rating of turbines 

and bypass flow checked by two or more discharge measurements a month. Flow regulated 

by gates from All-American Canal to Yuma Main Canal. Records show quantity of water 

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

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

returned to Colorado River through Yuma Main Canal wasteway, Similes downstream.

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

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

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

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

to irrigate about 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, water year October 1959 to September 1960

5250. Yuma Main Canal wasteway at Yuma, Ariz.

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

lat 32°44'00", long 114°37'20", in SWjSE^- sec. 26, T.16 S. , R.22 E., San Bernardino 

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

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

Main Canal. The wasteway discharges into Colorado River in SW-J- 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 1960. Monthly discharge only for some periods, published in WSP 1313.

Average discharge.--32 years (1928-60), 1,255 cfs (908,600 aere-ft per year).

Extremes.--1930-60: Maximum daily discharge, 2,020 cfs Dec. 24, 25, 1948; no flow for 

several days in 1937-39, 1945, 1950.

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

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

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

mile above its mouth.

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

Reclamation.

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

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

InTaKe, lat 32°43'50", long 114°37'10", in SWjSE^ sec.26, T.16 S., R.£2 E., San Bernardino meridian, on left bank in California, 1,645 ft downstream from center of Yuma 

Main Canal wasteway gates and 3-| miles downstream from siphon-drop powerplant. At outlet, in NW^NE^ 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 1960. Monthly discharge only prior to Octoher 1938, published in WSP 1313. Diversion from Yuma Main Canal for irunicipal supply 

for Yuma, October 1947 to September 1960 (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. 36 years, 475 cfs (343,900 acre-ft per year).

Extremes. 1930^0: 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 or no gag?-height record, 

which are good, and those below 50 cfs, which are poor. Daily discharge computed from 

relation between discharge and head on siphon, which is difference between intake and 

outlet gages. Discharge measurements made every two weeks with additional measurements 

to define unusual conditions. Records show quantity of water deliverei through Colorado River siphon for irrigation of 44,915 acres (1959 determination) in the Valley 

Division of the Yuma project and for supplementary municipal supply fo" city of Yuma. 

Records of chemical analyses and water temperatures for the water year 1960 are given 

in WSP 1744.

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

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

Revisions. Revised figures of diversion for supplementary municipal supply for city of 

Yuma for the-water years 1958-59, superseding those published in WSP 1563 and 1633, are 

given herewith.

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

Records available.--February 1939 to September 1960. Prior to October 19"3, monthly discharge only, published in WSP 1313. Prior to October 1956, published as Pilot Knob 

wasteway near Pilot Knob, Calif.

Gage.--Water-stage recorder on right bank of Ail-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, 4,390 cfs Jan. 8; no flow for many days. 

1939-60: Maximum daily discharge, 8,35U cfs Jan. 26, 1958; no flow for long periods.

Remarks. Records excellent. Daily discharge computed from flowmeter 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 durirg flow. Records show water released through Pilot Knob powerplant and wasteway from Ail-American 

Canal and returned to Colorado River through Rockwood gates. Pilot Knob wasteway 

completed in summer of 1938 and first flow occurred Feb. 5, 1939. Pilot Knob powerplant was completed in January 1957 and first flow occurred Jan. 14, 1957. See table 

below for monthly return flow by Pilot Knob wasteway only.

Cooperation.--Midnight readings of flowmeter, recorder graph of forebay, and record of 

tailrace elevation and gate openings furnished by Imperial Irrigation District.

498 DISCHARGE AT PARTIAL-RECORD STATIONS AND MISCELLANEOUS SITES

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

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

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

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

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

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

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

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

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

are called measurements at miscellaneous sites.

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

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

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

table.

Low-flow partial-record stations

Measurements of streamflow in the area covered by this report made at low-flow, 

partial-record stations are given in the following table. Most of these measurements were 

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

These measurments, when correlated with the simultaneous discharge of a nearby stream 

where continuous records are available, will give a picture of the low-flow potentiality 

of stream. The column headed "Period of record" shows the water years in which measurements were made at the same, or practically the same, site.

DISCHARGE AT PARTIAL-RECORD STATIONS AND MISCELLANEOUS SITES 499

Crest-stage partial-record stations

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

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

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

tbe 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 

wster years for which the annual maximum has been determined.
