SURFACE WATER SUPPLY OF COLORADO RIVER

BASIN, 1921.

AUTHORIZATION AND SCOPE OF WORK.

This volume is one of a series of 14 reports presenting records.of 

measurements of flow made on streams in the United States during 

the year ending September 30, 1921.

The data presented in these reports were collected by the United 

States Geological Survey under the following authority contained in 

the organic law (20 Stat, L., p. 394):

Provided, That this officer [the Director] shall have the direction of the Geological Survey and the classification of public lands and examination of the 

geological structure, mineral resources, and products of the national domain.

The work was begun in 1888 in connection with special studies 

relating to irrigation in the arid West. Since the fiscal year, ending 

June 30, 1895, successive sundry civil bills passed by Congress Have 

carried the following item and appropriations:

For gaging the streams and determining the water supply of the United States, 

and for the investigation of underground currents and artesian wells, and. for, the 

preparation of reports upon the best methods of utilizing the water resources.

Annual appropriations for the fiscal years ending June SO, 1895~ 1982.

In the execution of the work many private and State organizations 

have cooperated either by furnishing data or by assisting in collecting 

data. Acknowledgments for cooperation of the first kind are made 

in connection, with the description of each station affected; cooperation of the second kind is acknowledged on page'9.

2 SURFACE WATER SUPPLY, 1921, PART IX.

Measurements of stream flow have been made at about 5,200 

points in the United States and also at many points in Alaska and 

the Hawaiian Islands. In July, 1921, 1,350 gaging stations were 

.being maintained by the Survey and the, cooperating organizations. 

Many miscellaneous discharge measurements were made at other 

points. In connection with this work data were also collected in 

regard to precipitation, evaporation, storage reservoirs, river profiles, 

and water power in many sections of the country and will be made 

available in water-supply papers from time to time.

DEFINITION OP TERMS.

 . t '

The volume of water flowing in a stream the "run-off" or "dis-

^harge" is expressed in various terms, each of which has become 

.associated with a certain class of work. These terms may be divided 

into two groups (1) those that represent a rate of flow, *as secondfeet, gallons per minute, miners' inches, and discharge in second-feet 

per square mile, and (2) those that represent the actual quantity 

of water, as run-off in inches, acre-feet, and millions of cubic feet. 

The principal terms used in this series of reports are second-feet, 

second-feet per square mile, run-off in inches, acre-feet, and millions 

of cubic feet. They may be defined as follows:

"Second-feet" is an abbreviation for "cubic feet per second." 

A second-foot is the rate of discharge of water flowing in a channel 

of rectangular cross-section 1 foot wide and 1 foot deep at an average 

velocity of 1 foot per second. It is generally used as a fundamental 

unit from which others are computed.

"Second-feet per square mile" is the average number of cubic feet 

of water flowing per second from each square mile of area drained, 

on the assumption that the run-off is distributed uniformly both as 

regards time and area.

"Run-off in inches" is the depth to which an area would be covered if all the water flowing from it in a given period were uniformly 

distributed on the surface. It is used for comparing run-off with 

rainfall, which is usually expressed in inches. '

An "acre-foot," equivalent to 43,560 cubic feet, is the quantity 

required to cover an acre to the depth of 1 foot. The term is commonly used in connection with storage for irrigation.

The following terms not in common use are here defined:

"Stage-discharge relation," an abbreviation for the term "relation 

of gage height to discharge."

"Control," a term used to designate the section or sections of the 

stream channel below the gage which determine the stage-discharge 

relation at the gage. It should be noted that the control may not 

be the same section or sections at all stages.

EXPLANATION OF DATA. 3,

The "point of zerp flow" for a gaging station is that point on the 

gage the gage height at which water ceases to flow over the. 

control.

EXPLANATION OF DATA.

The data presented in this report cover the year beginning October 

1, 1920, and ending September 30, 1921. At the beginning of. 

January in most parts of the United States much of the precipitation' 

in the preceding three months is stored as ground water, in the form 

of snow or ice, or in ponds, lakes, and swamps, and this stored water, 

passes off in the streams during the spring break-up. At the end 

of September, on the other hand, the only stored water available 

for run-off is possibly a small quantity in the ground; therefore the 

run-off for the year beginning October 1 is practically all derived, 

from precipitation within that year. ; .

The base data collected at gaging stations consist of records of 

stage, measurements of discharge, and general information used to 

supplement the gage heights and discharge measurements in determining the daily flow. The records of stage are obtained either from 

direct readings on a staff gage or from a water-stage recorder that 

gives a continuous record of the fluctuations. Measurements of 

discharge are made with a current metey by the general methods 

outlined in standard textbooks on the measurement of river discharge. (See Pis. I, II.)

From the discharge measurements rating tables are prepared that 

give the discharge for any stage. The application of the daily gage 

heights to these rating tables gives the daily discharge from which the 

monthly and yearly mean discharge is determined.

The data presented for each gaging station in the area covered by 

this report comprise a description of the station, a table giving records 

of discharge measurements, a table showing the daily discharge of 

the stream, and a table of monthly and yearly discharge and run-off.

If the base data are insufficient to determine the daily discharge, 

tables giving daily gage height and records of discharge measurements are published.

The description of the station gives, in addition to statements 

regarding location and equipment, information in regard to any conditions that may affect the permanence of the stage-discharge relation, 

covering such subjects as the occurrence of ice, the use of the stream 

for log driving, shifting of control, and the cause and effect of backwater. It gives also information as to diversions that decrease .the 

flow at the gage, artificial regulation, maximum and minimum 

recorded stages, and the accuracy of the records.

The table of daily discharge gives, in general, the discharge in 

second-feet corresponding to the mean of the gage heights read each 

day. At stations on streams subject to sudden or rapid diurnal ,

fluctuation the discharge obtained from the rating table and the 

mean daily gage height may not be the true mean discharge for the 

day. If such stations are equipped with water-stage recorders the 

mean daily discharge may be obtained by averaging discharge at 

regular intervals during the day or by use of the discharge integrator, 

an instrument operating on the principle of the planimeter and 

containing as an essential element the rating curve of the station. 

In the table of monthly discharge the column headed "Maximum" 

gives the mean flow for the day when the mean gage height was 

highest. As the gage height is the mean for the day it does not 

indicate correctly the stage when the water surface was at crest 

height and the corresponding discharge was consequently larger than 

given in the maximum column. Likewise, in the column headed 

"Minimum" the quantity given is the mean flow for the day when 

the mean gage height was lowest. The column headed "Mean" is 

the average flow in cubic feet per second during the month. On this 

average flow are based computations recorded in the remaining 

columns, which are defined on page 2.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS.

The accuracy of stream-flow data depends primarily (1) on the 

permanence of the stage-discharge relation, and (2) on the accuracy 

of observation of stage, measurements of flow, and interpretation of 

records.

A paragraph in the description of the station gives information 

regarding the (1) permanence of the stage-discharge relation, (2) 

precision with which the discharge rating curve is defined, (3) refinement of gage readings, (4) frequency of gage readings, and (5) 

methods of applying daily gage height to the rating table to obtain 

the daily discharge.

For the rating tables "well defined" indicates, in general, that the 

rating is probably accurate within 5 per cent; "fairly well defined," 

within 10 per cent; "poorly defined," within 15 to 25 per cent. 

These notes are very general and are based on the plotting of the 

individual measurements with Reference to the mean rating curve.

The monthly means for any station may represent with high accuracy the quantity of water flowing past the gage, but the figures 

showing discharge per square mile and depth in inches may be misleading owing to the inclusion of large noncontributing districts in the 

measured drainage area, and they may also be subject to gross errors 

caused by lack of information concerning water diverted for irrigation 

or other use, or by inability to interpret the effect of artificial regulation 

of the flow of the river above the station. "Second-feet per square 

mile" and "run-off in inches" are therefore not computed if such 

errors appear probable. The computations are also omitted for sta-

tioflfe on streams draining areas in which, the annual rainfall is less than 

20 iAches. ^.11 figures representing ( ' second-feet per square mile'' and.« 

"f\jai-o:ff in inches" previously published by tile'Survey should be 

used with caution because of possible inherent sources of error not 

known to the Survey. . . i

T|ie table of monthly discharge gives only a general idea of the1 

flow at the station and should not be used for other than preliminary 

estimates; the tables of daily discharge allow more detailed studies 

of the variation in flow. It should be borne in mind, also, that the 

observations in each succeeding year may be expected to throw new 

ligh£ on data previously published.

Investigation of water resources by the United States Geological 

Survey has consisted in large part of measurements of the volume of 

flow streams and studies of the conditions affecting that flow, but 

it has comprised also investigation of such closely allied subjects as 

irrigation, water storage, water powers, ground waters, and quality of 

waters. Most of the results of these investigations have been published in the series of water-supply papers, but some have appeared in 

the monographs, bulletins, professional papers, and annual reports.

The results of stream-flow measurements are now published annually in 12 parts, each part covering an area whose boundaries coincide with natural drainage features as indicated below:

Part I. North Atlantic slope basins.

II. South Atlantic slope and eastern Gulf of Mexico basins.

III. Ohio River basin.

IV. St. Lawrence River basin.

V. Upper Mississippi River and Hudson Bay basins.

VI. Missouri River basin. . ,

, NOTE. No stream-flow data are given in the Fifteenth and Seventeenth annual reports.

The records at most of the stations discussed in these reports extend over a series of years, and miscellaneous measurements at many 

points other than regular gaging stations have been made each year. 

An index of the reports containing records obtained prior to 1904 has 

been published in Water-Supply Paper 119.

The following table gives, by years and drainage basins, the numbers of the papers on surface-water supply published from 1899 to 

1920. The data for any particular station will be found in the 

reports covering the years during which the station was maintained. 

For example, data from 1902 to 1921 for any station in the area 

covered by Part III are published in Water-Supply Papers S3, 98,

scale"'' 1:500,000).

RECORDS AVAILABLE. July 22, 1904, to September 30, 1909; September 23, 1910, 

to September 30, 1921.

GAGE. Chain gage on downstream side of bridge; read by G. C. Henry. Prior 

to Appil 16, 1906, a staff gage 1,000 feet downstream, set to datum 6.07 feet 

lower, was used.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Bed composed of well-compacted gravel. Control 

150 feet downstream; shifting at long intervals. Banks not subject to overflow.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 8.7 feet at 

5 a. m. June 15 (discharge, 10,300 second-f eet) ; minimum discharge occurred 

during winter.

1904-1909; 1910-1921: Maximum stage recorded in 1921; minimum 

discharge occurs during winter (estimated at 63 second-feet on February 

15 and 25-27, 1908).

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. Court decrees for diversions of 800 second-feet from Colorado

across the divide into headwaters of Cache la Poudre River. Under this 

decree 9,200 acre-feet was diverted during 1921.

REGULATION. Diurnal fluctuation during spring of year from alternate melting 

and freezing of mountain snow. No artificial regulation.

ACCURACY. Stage-discharge relation shifted considerably during spring breakup; affected by ice November 6 to April 5. Rating curve used from April 

1 to September 30 well defined. Shifting-control method used for October 

and November with previous rating curve as standard. Gage read to 

hundredths twice daily; readings for September apparently in error. Daily 

discharge ascertained by applying mean daily gage height to rating table 

except for periods of ice effect and period for which gage readings are in 

error, for which it was ascertained as noted in footnote to tables of daily 

discharge and except for period for which shifting-control method was used. 

Open-water records good except for September, for which they are fair; 

winter records fair.

112 SURFACE WATER SUPPLY, 1921, PART IX-.

COLORADO BI7EB AT GIENWOOD SPRINGS, COIO.

LOCATION. In sec. 9, T. 6 S., R. 89 W., at Glenwood Springs, Garfield County. 

No Name Creek enters Colorado River 2 miles above station and Roaring 

Fork half a mile below.

DBAINAGE AREA. 4,560 square sniles (revised; measured on map of Colorado, 

scale 1:500,000).

RECOBDS AVAILABLE. January 1, 1900,. to September 30, 1921; also May 12 

to July 17, 1899, at point just above Roaring Fork.

GAGE. Friez water-stage recorder on right bank in front of power house; installed May 17, 1910; inspected by Forest Service employee. See WaterSupply Paper 175 for history of early gages and gage used in 1905 which was 

also used until May 17, 1910. No change in gage datum.

DISCHARGE MEASUREMENTS.-" Made from cable beneath State Street bridge, a 

third of a mile below gage.

CHANNEL AND CONTROL. Bed composed of well-compacted gravel, on which silt 

is deposited. Control at riffle 300 feet downstream; slightly shifting. 

Banks not subject to overflow except at extreme high stages.

EXTREMES OF DISCHARGE. Maximum stage during year, from water-stage 

recorder, 12.3 feet at 8 p. m. June 15 (discharge, 29,000 second-feet); minimum stage, 1.6 feet at 5 p. m. February 6 (discharge, 80 second-feet).

1900-1921: Maximum stage recorded, 12.55 feet at noon June 14 and 

15, 1918 (discharge, 30,100 second-feet); minimum stage recorded that of 

February 6, 1921.

ICE. Stage-discharge relation not affected by ice. Hot water from springs 

keeps river open.

DIVERSIONS. Court decrees for diversion of 48 second-feet of water from Colorado River for irrigation between this station and Hot Sulphur Springs and 

1,250 second-feet for power. Water diverted for power is returned to river 

above Glenwood Springs.

REGULATION. Shoshone power plant of Colorado Power Co., 7 miles upstream, 

controls flow during day at low water but has insufficient pondage to control 

it for more than a few hours.

ACCURACY. Stage-discharge relation practically permanent. Rating curve 

well defined. Operation of water-stage recorder fairly satisfactory (see 

footnote to daily-discharge table). Daily discharge ascertained by applying 

to rating table mean daily gage height obtained from recorder, graph by inspection or, for days of considerable diurnal fluctuation, by averaging the 

bi-hourly discharge, except for periods during which recorder did not operate 

for which it was ascertained as indicated in footnote to daily-discharge table. 

Records excellent except for periods of missing gage-height record, for which 

they are fair.

COOPERATION. Gage-height record furnished by United States Forest Service.

Bureau states that highest stage known was about 18.5 feet on July 4, 1884 

(discharge estimated from extension of rating curve and levels across overflow, 125,000 second-feet); minimum stage, 1.9 feet August 26-30, 1919 

(discharge, 1,270 second-feet).

ICE. Stage-discharge relation seriously affected by ice; daily discharge not 

determined during winter.

DIVERSIONS. Court, decrees for diversions of 788 second-feet from Colorado 

River between the Palisade station and Fruita.

RE GUL ATION . None.

ACCURACY. Stage-discharge relation not permanent. Rating curve fairly well 

defined below 40,000 second-feet. Gage read to tenths twice daily. Daily 

discharge ascertained by applying mean daily gage height to rating table 

except for period affected by ice December 14 to January 31 and shifting 

control September 11-30. Records good below 40,000 second-feet and fair 

above.

J COLORADO BITER WEAR TOPOCE, ARIZ.

LOCATION. In E. J^ sec. 16, T. 7 N., R. 24 E., in Mohave Canyon 1% miles 

below Atchison, Topeka & Santa Fe Railway bridge at Topock, Mohave 

County, and 16 miles (by main channel of river) below Needles, Calif.

DBAINAGE ABEA. 171,000 square miles.

RECOBDS AVAILABLE. February 1, 1917, to September 30, 1921..

GAGE. Stevens continuous water-stage recorder on right bank at mouth of 

Mohave Wash just above point where river enters a narrow section of 'the 

canyon. .

DISCHABGE MEASUREMENTS. Made from cable just below gage.

CHANNEL AND CONTROL. Channel straight above and below gage. Above the 

gage the channel is wide and the bed of loose sand is constantly shifting. 

At low stages large sand bars form numerous islands between Topock and 

the gage. Below the gage the river enters a steep walled rock canyon and 

the channel contracts from about 800 feet to 400 feet. The bed in the canyon scours during floods, and fills during low stages. The control is 

indefinite.

EXTREMES OP DISCHARGE. Maximum stage during year from water-stage recorder, 28.2 feet on June 22 (discharge, 174,000 second-feet); minimum discharge 5,900 second-feet on December 27.

1917-1921: Maximum stage and discharge occurred on June 22, 1921;. 

minimum discharge, 4,100 second-feet on January 16, 1919.

DIVEBSIONS. Water is diverted for irrigation and power development from main 

river and tributaries above the station.

ACCUBACY. Stage-discharge relation not permanent. During the year 30 

discharge measurements were made covering a range in discharge from 8,000 

to 80,000 second-feet. Operation of water-stage recorder satisfactory 

during most of the year. Mean daily gage heights determined by inspecting recorder graph. Daily discharge ascertained by shifting-control 

method. Records fair.

Daily discharge, in second-feet, of Colorado River near Topock, Ariz., for the year

ending Sept. 30, 1921.

COLORADO RIVER AT YUMA, ARIZ.

LOCATION. In NE. ^ NE. ^ sec. 35, T.16 S., R. 22 E., San Bernardino base

and meridian, 100 feet upstream from Southern Pacific Co.'s original

bridge at Yuma, Yuma County. Since the change in channel on June 7,

1920, Gila River enters from the east 5 miles upstream from this station. 

DRAINAGE AREA. 242,000 square miles (measured on map compiled from

best available maps of the Colorado River basin). 

RECORDS AVAILABLE. April 1, 1878, to September 30, 1921. Gage heights

only before January 1, 1902. 

GAGE. Vertical staff in two sections on left bank; zero of gage is 102.79 feet

above mean sea level. Published incorrectly in Water-Supply Paper 509. 

DISCHARGE MEASUREMENTS. Made from cable 1,000 feet downstream from gage. 

CHANNEL AND CONTROL. Bed composed of shifting sand and silt; 'subject to

much scour during high water. No well-defined control. 

EXTREMES OP DISCHARGE. Maximum mean daily discharge during year, 186,000

second-feet on June 28; minimum mean daily discharge, 5,100 second-feet

on December 27. 

1902-1921: Maximum mean daily discharge, 240,000 second-feet, January

22,1916; minimum mean daily discharge, 1,800 second-feet January 16, 1919.

Maximum discharge on January 22, 1916, was caused by a flood from Gila

River. 

DIVERSIONS. Water is diverted for irrigation and power from main river and

tributaries above station. At Laguna dam about 15 miles upstream water

is diverted for the Yuma project of the United States Bureau of Reclamation.

The annual diversion is about 500,000 acre-feet. Some of the water diverted

is returned to the river at the spillway below the gaging station at Yuma. 

REGULATION. Flow affected at times by sluicing at Laguna dam. 

ACCURACY. During the year 164 discharge measurements were made at the

station; daily discharge determined by shifting-control method. 

COOPERATION. Complete records furnished by the Bureau of Reclamation,

but data have been revised slightly to conform to the computation rules

used by the United States Geological Survey.

FRASER RIVER NEAR ARROW, COIO.

LOCATION. In NE. M sec. 4, T. 2 S., R. 75 W., a quarter of a mile from Vasquez 

siding on Denver & Salt Lake Railroad in Arapahoe National Forest and 

1-Hj miles southwest of Arrow, Grand County. Nearest tributary enters 

half a mile above.

DEAINAGE AREA. 29 square miles, revised (measured on special map).

RECORDS AVAILABLE. September 23, 1910, to September 30, 1921.
20 SURFACE WATER SUPPLY, 1921, PART IX.

-GAGE. Friez water-stage recorder on left bank 300 feet upstream from old 

logging road crossing at Vasquez; inspected by forest ranger. Prior to 

June 3, 1916, vertical staff attached to downstream side of bridge on trail to 

Arrow and a quarter of a mile above railroad bridge was used. During 

winter, readings taken from staff gage 1 mile upstream at railroad bridge.

DISCHARGE MEASUREMENTS. Made from footbridge near gage or by wading.

CHANNEL AND CONTROL. Bed composed of boulders and coarse gravel; fairly 

permanent. No well-defined control. Banks are not subject to overflow.

EXTREMES OF DISCHARGE. Maximum stage during year from water-stage 

recorder, 2.5 feet at 8 p. m. June 11 (discharge, 525 second-feet); minimum 

discharge probably occurred during winter.

1911-1921: Maximum discharge recorded, 820 second-feet at 9 p. m., 

June 13, 1918 (gage height, 2.9 feet) ; minimum discharge, 2 second-feet on 

March 30 1912 (gage-height, 0.60 foot).

ICE. Stage-discharge relation affected by ice.

DIVERSIONS. Court decrees for diversions of 53 second-feet across divide from 

headwaters of Fraser River into headwaters of Clear Creek. During 1921 

100 acre-feet were diverted. Below station, court decrees for 74 secondfeet for irrigation and 61 second-feet for placer mining and power.

REGULATION. Diurnal fluctuation during spring, caused by alternate melting 

and freezing of mountain snow. No artificial regulation.

ACCURACY. Stage-discharge relation for regular station practically permanent; 

for winter station not permanent. Rating curve for regular station well 

defined between 15 and 400 second-feet. Staff gage read to hundredths 

once daily from October 8 to May 21. Operation of water-stage recorder 

satisfactory except for short periods, as shown in footnote to table of daily 

discharge. Daily discharge ascertained by applying to rating table one 

daily gage reading or mean daily gage height determined by inspecting 

gage-height graph. Records excellent except during winter, for which they 

are fair.

subject to overflow.

EXTREMES OF DISCHARGE. Maximum stage not recorded, as gage was not read

during period of high water. Minimum discharge, 7 second-feet March 12.

1911-1921: Maximum stage recorded, 4.0 feet, June 5, 1912 (discharge,

1,010 second-feet); minimum stage, 0.01 foot at 7 a. m., October 15, 1917

(discharge, 1 second-foot).

ICE. Stage-discharge relation not affected by ice except for occasional short' 

periods.

DIVERSIONS. Court decrees for diversions of 6 second-feet from Eagle River 

above station, and also a decree for diversion to the Arkansas basin of 18.5 

second-feet from Piney Creek, a tributary. During 1921, 1,850 acre-feet 

were diverted.

REGULATION. Diurnal fluctuation during spring, caused by alternate melting 

and freezing of mountain snow. Filling of Pando ice pond in fall reduces 

flow for a few days.

ACCURACY. Stage-discharge relation shifts between narrow limits. Rating 

curve well defined between 5 and 500 second-feet. Gage read to hundredths 

twice daily. Readings for July 10 to September 24 unreliable. Daily discharge ascertained by applying mean daily gage height to rating table, except 

as noted in footnote to table of daily discharge. Records fair.

UNCOMPAHGRE RIVER AT OURAT, COIO.

LQCJATION. Riyer; In sec. 31, T. 44 N., R. 7 W., in box canyon a short distance

upstream from highway bridge half a mile south of Ouray, Ouray County.

Nearest tributary,. Canyon Creek, enters 150 feet below; nearest tributary

above is Bear Creek.

Power-house flume: In tailrace of power-house flume in Ouray about 100

feet upstream from entrance to river. Water diverted from Uncompahgre

River above river station. 

DKAINAGE AREA. 44 square miles (measured on topographic map).
1PART it. ' '

S0 AVAILABLE. JanuaTy 2$, J.911, to September 30, 1921, for river statfon 

and February 25, 1916, to September 30, 1921, for power-house flume. 

Combined daily flow for river and flume are given, as intermittent operation 

of power house causes low-water flow in river to fluctuate to such an extent 

that one daily gage height does not represent essentially the mean daily 

stage. From January 7 to March 17, 1908, records were kept at dam of 

Ouray Electric Light & Power Co., 1 mile south of present-station,

GAGE. River: Stevens water-stage recorder installed April 22, 1919, and referred to vertical staff used since 1911 and attached to rock cliff at left side 

of stream 150 feet above mouth of Canyon Creek; inspected by T. J. Watkins. 

Power house flume: Vertical staff fastened to' side of wooden flume just 

below power house. " " 

DISCHARGE MEASUREMENT^". River: Made from footbridge at gage or by wading 

Flume: Made from footbridge just below gage.

CHANNEL AND CONTROL. River: Bed composed of small boulders. Control 

short distance downstream, shifting at intervals; station is in box canyon 

that has high vertical walls. :

Flume: Control is plank nailed across bottom of flume at lower end.

EXTREMES OP DISCHARGE. River: Maximum stage during year from water-stage 

recorder, 5.9 feet at 7p. m. June 11 (discharge, 1,930 second-feet); minimum 

stage, 0.28 foot at 10 a. m. December 25 (discharge, 0.5 second-feet).

1911-1921: Maximum stage recorded that of June 11 during 1921; 

minimum discharge, no flow February 2, 3, and 29, 1912.

ICE. Stage-discharge relation not affected by ice, a,s warm springs keep stream 

open.

T>iVERSIONS. No diversion above station other than pipe line whose flow is 

included in these records. '

REGULATION. Diurnal fluctuation during spring from alternate melting and 

freezing of mountain snow.

ACCURACY. River; Stage-discharge relation not permanent; no.t affected toy 

ice during winter-. Two standard rating curves fairly well defined used 

during the year. Operation of water-stage recorder satisfactory. Daily 

 discharge ascertained by applying to rating tables mean daily gage height 

determined by inspection of gage-height graph, or for days of considerable 

fl tuations during low water by averaging bihourly discharge, as noted in 

Jfootuote to table of daily discharge. Shifting-control method used during 

the year. Records good.

Flume: Daily discharge from October 1 to December 31 obtained by 

applying poorly defined rating table to one daily gage height, as diversion 

was continuous^ From January 1 to June 11 diversions were made inter* 

mittently, and discharge was determined from study of charts for riVgr 

station which is below diversion. No diversion subsequent to June 11. 

Records fair except from January to April, for which they are good.

Records of combined discharge of river and flume good except those for 

October to December which ar<e only fair, as the quantity of water diverted 

by the flume during the period is a large percentage of the total discharge.

DOLORES RIVER AT RICO, COIO.

LOCATION. In sec. 36, T. 40 N., R. 11 W., at highway bridge at upper edge of 

Rieo, Dolores County. Silver Creek jsnters just above station.

DRAINAGE ABE A. 83 square miles (measured on topographic map).

RECORDS AVAILABLE. June 9 to December 31, 1914; June 1, 1919, to June 10, 

1921, when station was destroyed by high water.

GAGE. Vertical staff fastened to right abutment used during 1914 and until 

August 12, 1919. 4On August 14, 1919, a chain gage referred to datum 1.84 

feet lower, was installed on bridge; read by G. E. Hicks.

DISCHARGE MEASUREMENTS. Made from single-span bridge or by wading.

CHANNEL AND CONTBOL. Bed composed of small boulders. Control 175 feet 

downstream at rapids composed of well-compacted boulders; shifting during 

extreme high water.

EXTREMES OF DISCHARGE. Maximum stage not recorded, as gage was destroyed 

by flood June 11; minimum stage, 0,90 foot at 5 p. mM January 3 (discharge, 

10 second-feet).

ICE. Stage-discharge relation slightly affected by ice for short periods.

REGULATION. None.

DIVERSIONS. The Syndicate Mining Co. diverts about 2 second-feet from 

Horse Creek, a tributary of Dolores River, and carries it to pressure pipe 

located several hundred yards below gage. Water is diverted from April to 

November. The flow through the pipe varies between 1.7 and 2.0 secondfeet, but this does not include the entire amount diverted as considerable 

is wasted over a spillway just below the gage. No other diversions above.

ACCURACY. Stage-discharge relation hot permanent; affected by ice for short 

periods. Rating curve not well defined above 200 second-feet. Gage read 

to hundredths twice daily. Daily discharge ascertained by applying mean 

daily height to rating table, except as explained in footnote to table of daily 

discharge. Records good.

COOPERATION. The Syndicate Mining Co. furnished the gage-height record.

GEEEN RIVER AT LITTLE VALLEY, WEAR GREEN RIVER, UTAH.

LOCATION. In sec. 4, T. 22 S., R. 16 E., 1 mile above old Little Valley ferry

, and 6 miles downstream from Green River, Emery County. San Rafael

River enters Green River 16 miles downstream, in sec. 25, T. 23 S., R. 16 E.

DRAINAGE AREA. 41,000 square miles (measured in 1915, on best available 

maps of Colorado River basin).

AVAILABLE. December 18, 1910, to September 30, 1921. Records 

obtained at Green River (known also as Elgin or Blake) from 1894 to 1899, 

and 1905 to 1911, give practically the same flow.

. Stevens continuous water-stage recorder on left bank 1 mile above old 

ferry, since December 16, 1917, referred to hook gage inside well and inclined staff gage outside; inspected by A. I. Anderson. For history of 

previous gages see Water-Supply Paper 479.

DISCHARGE MEASUREMENTS. Made from car on old ferry cable.

CHANNEL AND CONTROL. Bed composed of gravel and sand. Fairly permanent 

..,. gravel riffle two-thirds of a mile below gage. Banks high and not subject 

to overflow.

EXTREMES OF DISCHARGE.- Maximum stage during year, from water-stage recorder, J.4.12 feet at 11 a. m. June 17 (discharge, 65,500 second-feet); minimum stage recorded, 0.02 foot at 2 p. m. December 18 (discharge, 1,040 

second-feet).

1894-1899; 1905-1921: Maximum discharge recorded, 68,800 secondfeet May 29, 1897; minimum stage recorded, 0.95 foot December 1, 1919 

(discharge, 510 second-feet).

ICE. Stage-discharge relation affected by ice nearly every winter.

DIVERSIONS. Station is below practically all diversions from Green River.

REGULATION. None.

ACCURACY, rStage-discharge relation changed slightly March 16-18, and considerably May 16 to June 6; affected by ice January 3-31. Rating curves 

well defined between 800 and 70,000 second-feet. Operation of water-stage 

recorder satisfactory except December 16 to January 2, for which record is 

slightly uncertain; January 3-31, when recorder was not operating becuase 

of ice; and June 8-11, July 8-12, 24, and August 5-6, 1-3, when no record 

was obtained. Daily discharge ascertained by applying to rating table 

mean daily gage height determined from recorder graph or, for periods of 

faulty gage-height record by comparison with flow at a gaging station maintained at Ouray, Utah, by Utah Power & Light Co. For period of ice effect 

mean discharge ascertained by means of one meter measurement, fragmentary gage-height record, weather records, and observer's notes. Openwater records excellent; winter records fair.

COOPERATION. Since December 16, 1917, station has been maintained in cooperation with Utah Power & Light Co., which made most of the discharge 

measurements.

MAST FORK AT EAST FORK CANAL, WYO.

LOCATION. In sec. 10, T. 31 N., R. 106 W., 300 feet above intake of East Fork 

canal, 18 miles southeast of Boulder, Sublette County. Nearest tributary, 

Canal Creek, enters just below.

DRAINAGE AREA. 106 square miles (measured on base map of Wyoming, scale 

1:500,000).

RECORDS AVAILABLE. During irrigation seasons of 1916, 1917, and 1921.

GAGE. Vertical staff-on left bank; read by Robert Hawkins.

DISCHARGE MEASUREMENTS. Made from cable near gage or by wading.

CHANNEL AND CONTROL. Bed composed of small boulders; control 100 feet 

downstream, apparently permanent.

J(JIXTREMES OP DISCHARGE. 1916-1917; 1921: Maximum stage recorded during 

irrigation seasons, 4.6 feet on June 23 and 25, 1917 (discharge, 1,400 secondfeet); minimum stage, 1.0 foot September 23, 1916, and August 20-23, 

25-28, and 30, 1921 (discharge, 8 second-feet).

ICE. No data.

DIVERSIONS. Prior to July 1, 1921, there was adjudicated diversion of 26 

second-feet from East Fork above the station.

REGULATION. Flow regulated to small extent by many small lakes at headwaters. Alternate melting and freezing of mountain snow causes diurnal 

fluctuation during spring.

ACCURACY. Stage-discharge relation permanent. Rating curve fairly well 

defined below 1,200 second-feet. Gage read to tenths once daily. Daily 

discharge ascertained by applying gage-height to rating table. Records 

fair.

COOPERATION. Gage-height record furnished by East Fork Canal Co.

1911, to June 5, 1914, fragmentary records were obtained at the power plant, 

the total flow of the creek being determined by including the discharge from 

the tailrace. Records are also available for a point below the mouth of 

Dry Fork from March 15, 1900, to December 31, 1904.

GAGE. Stevens continuous water-stage recorder on left bank three-quarters of a 

mile above heading of power canal, installed June 14, 1919. Recorder 

inspected and supplementary staff gage read once a week by Adam Erickson 

and William Thomas.

4.18 feet in February and March (discharge, 32 second-feet).

1911-1921: Maximum discharge recorded that of May 29, 1921; minimum discharge, 26 second-feet on February 7, 1920 (gage height, 3.36 feet).

ICE. None.

DIVERSIONS. None above station.

REGULATION. None.

ACCURACY. Stage-discharge relation not affected by ice. Changes in channel 

conditions caused slight change in stage-discharge relation about June 10, 

1921. Rating curves well defined from 30 to 300 second-feet and extended 

above. Operation of water-stage recorder satisfactory except November 15 

to March 25 and June 6-10. Weekly staff gage readings obtained during 

winter and no record June 6-10. Daily discharge determined only for 

days when gage was read during the period November 15 to March 25.

NORTH FORK OF DUCHESNE RIVER NEAR HANNA, UTAH.

LOCATION. In NW. % NE. M sec. 35, T. 2 N., R. 9 W., TJinta special base and 

meridian, 250 feet below Hades Creek, 6 miles above confluence with West 

Fork, and 10 miles northwest of Hanna, Duchesne County.

DRAINAGE AREA. ^75 square miles (measured on topographic map).

RECORDS AVAILABLE. August 16 to September 30, 1921.

GAGE. Vertical enamel staff on left bank 10 feet downstream from cable; read 

by V. R. Savage.

DISCHARGE MEASUREMENTS. Made from cable or by wading.

CHANNEL AND CONTROL. Channel straight for half a mile above gage; makes 

sharp turn to left 50 feet below gage. Steep cobble riffle immediately below 

gage. One channel at all stages. Bed of gravel and small boulders. Right 

bank high. Left bank lower but probably not subject to overflow. Stage of 

zero flow 0.8 foot as determined October 1, 1921.

EXTREMES OP DISCHARGE. Extremes for the year do not occur during period of 

present records.

ICE. Stream probably freezes over at times each winter.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Rating curve for gage-height records thus far obtained is based on 

two discharge measurements made August 16 and October 1, 1921, and point 

of zero flow on October 1. It is well defined for range in stage occurring 

during period of records. Gage read to hundredths once daily except September 25-29. Daily discharge determined by applying daily gage height 

to rating table and interpolating for September 25-29. Records good.

The following discharge measurement was made by Purton and Woolley: 

August 16, 1921: Gage height, 1.16 feet; discharge, 74 seoond-feet.

DUCHESNE RIVER NEAR TABIONA, UTAH.

LOCATION. In SW. J^ sec. 17, T. 2 S., R. 6 W., Uinta special base and meridian, 

at highway bridge 8 miles southeast of Tabiona, Duchesne County, and 

5*>4 miles above Rock Creek.

DRAINAGE AREA. 352 square miles.

RECORDS AVAILABLE. January 16, 1919, to September 30, 1921.

GAGE. Stevens steel tape gage on downstream side of bridge; installed March 

8, 1920; read by Lyman Duke.

DISCHARGE MEASUREMENTS. Made by wading or from bridge.

CHANNEL AND CONTROL. Channel composed of gravel and sand.* Left bank 

high and not subject to overflow. Right bank overflowed at extreme high 

stage allowing water to pass around the bridge. Gravel riffle 50 feet below 

gage. Zero flow at gage height 0.9 foot as determined on September 21, 1919.

EXTREMES OP DISCHARGE. Maximum discharge about 2,500 second-feet on 

June 13; uncertain because gage readings for that time are doubtful and 

river was over right bank. Minimum discharge, 83 second-feet on February 

26 (gage height, 9.40 feet).

 >. 1919-1921: Maximum discharge that of June 13, 1921. Minimum discharge probably less than 70 second-feet in January, 1919, when river was 

frozen over.

ICE. River freezes over each winter.

DIVERSIONS. Some small diversions for irrigation above this station.

REGULATION. None.

ACCURACY. Stage-discharge relation below 800 second-feet changed during 

high water about May 31; affected by ice November 29, 30, and December 

13 to January 21. Rating curves fairly well defined. Gage read to hundredths once a day throughout the year. Daily discharge ascertained by 

applying daily gage height to rating table, except for period of ice effect 

and period June 14-24 for which gage readings are doubtful. Discharge 

for period of ice effect estimated from observer's notes, temperature records, 

and comparison with flow of Duchesne River at ,Duchesne. Discharge 

for period June 14-24 estimated from comparison with flow of Duchesne 

River at Duchesne. Records good.

DUCHESNE RIVER AT DUCHESNE, UTAH;

LOCATION. In NW. J^ sec. 1, T. 4 S., R. 5 W., Uinta special base and meridian, 

half a mile north jof post office at Duchesne, Duchesne County, at bridge 

on road from Duchesne Jo Tabiona, half a mile above mouth of Strawberry River.

DRAINAGE AREA. 660 square miles.

RECORDS AVAILABLE. December 3, 1917, to September 30, 1921.

GAGE. Chain gage on downstream handrail of bridge near right bank; read 

by E. S. Winslow.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Channel straight for several hundred feet below gage. 

Prior to high water in 1921 main channel from upstream approached bridge 

at sharp angle from the right and at low water a bar under bridge caused 

two separate channels which reunited a few feet below gage. Since high 

water, stream has been in one channel normal to bridge resulting in a straight 

channel from a hundred feet above gage to several hundred feet below. 

Bed composed of gravel and cobbles. The head of a long heavy gravel 

riffle is a short distance below gage. Banks are low but not subject to 

overflow. Stage of zero flow at gage height 2.6 feet as determined August 4 

and 18, 1921.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 8.40 feet on 

June 13 (discharge, 4,060 second-feet). Minimum discharge probably less 

than 150 second-feet in latter part of December when stage-discharge relation 

was affected by ice.

1918-1921: Maximum discharge that of June 13, 1921. Minimum 

discharge, 53 second-feet July 29 and August 23-27, 1919.

ICE. Stream freezes every winter.

DIVERSIONS. Below all diversions above mouth of Strawberry River; numerous 

diversions above and below station. Rock Creek enters between this 

station and the station near Tabiona.

REGULATION. None except by diversion.

ACCURACY. Stage-discharge relation changed during high water of about 

June 12; also changed slightly during winter; affected by ice December 10 

to February 23. Rating curves fairly well defined. Gage read to halftenths once a day except September 26-30. Daily discharge ascertained 

by applying daily gage height to rating table except as follows: Discharge 

for period of ice effect estimated from temperature records, observer's 

notes, and hydrographic study of flow at this station in conjunction with that 

of Duchesne River at Myton, Strawberry River at Duchesne, and Lake 

Fork near Myton; interpolated for September 26-30. Records good.

RECORDS AVAILABLE. October 26, 1899, to November 30, 1910, and July 26, 

1911, to September 30, 1921.

GAGE. Chain gage on upstream rail near the left end of steel highway bridge; 

installed August 6, 1910; read by Owen Smith.

DISCHARGE MEASUREMENTS. Made from the highway bridge or by wading about 

500 feet below the bridge.

CHANNEL AND CONTROL. Bed composed of coarse gravel; banks comparatively 

low but not likely to be overflowed, although they are subject to erosion 

during high water. Current comparatively swift and makes an angle with 

the bridge at low stages. Gravel riffle at ford 100 or 200 feet below the 

gage.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 7.8 feet at 

9.30 a. m. June 12 and 8 a. m. June 13 (discharge, 9,500 second-feet); minimum stage recorded, 1.8 feet on October 1 and 2 (discharge, 285 secondfeet).

1899-1921: Maximum stage recorded, 7.4 feet, June 20, 22, and 23, 1917 

(discharge, 9,69*0 second-feet). Minimum stage recorded, 0.75 foot at 

8.30 p. m. August 23 and 8 a. m. August 24, 1919 (discharge, 8 second-feet).

ICE. Stage-discharge relation seriously affected by ice every winter.

DIVERSIONS. Much of the low-water flow of the river and its tributaries is 

diverted for irrigation above the station.

REGULATION. Annual run-off is affected by storage in the United States Bureau 

of Reclamation reservoir on Strawberry River, one of the main tributaries.

ACCURACT. Stage-discharge relation below 1,500 second-feet changed during 

high water in June and July, and again during freshet August 31 to September 5; affected by ice November 28 to February 28. Rating curves well 

defined below 6,000 second-feet and extended above. Gage read to halftenths twice a day. Readings reported for the periods March 11-31 and 

August 31 to September 5 discarded as unreliable. Daily discharge ascertained by applying mean daily gage height to rating table except as follows: 

For periods of ice effect discharge was estimated from observer's notes, 

recorded gage heights, weather records, and hydrographic comparison with 

Duchesne River at Duchesne, Strawberry River at Duchesne, and Lake 

Fork near Myton; for March 11-31 and August 31 to September 5, discharge 

estimated from hydrographic study as for ice periods; discharge interpolated 

October 24, May 25, 26, and September 21 and 22 because gage was not 

read. Records good.

STRAWBERRY RIVER AT DUCHESNE. UTAH.

LOCATION. In E. 3^ sec. 2, T. 4 S., R. 5 W., Uinta special base and meridian, at 

Winslow's ranch, 1 mile west of post office at Duchesne, Duchesne County, 

half a mile above mouth of Indian Canyon, a small tributary entering from 

south, and 13^ miles above confluence of Strawberry and Duchesne rivers.

DRAINAGE AREA. 1,040 square miles (measured on topographic maps).

RECORDS AVAILABLE. June 10, 1908, to November 30, 1910; March 16, 1914, 

to September 30, 1921.

GAGE. Vertical staff installed July 30, 1918, on downstream side of right abutment of bridge; read by E. S. Winslow. For gages used prior to July 30, 

1918, see Water-Supply Paper 479.

DISCHARGE MEASUREMENTS. Made from cable just below bridge or by wading.

CHANNEL AND CONTROL. Channel straight for several hundred feet above and 

below gage. Bed composed of sand and fine gravel. Gravel riffle 200 feet 

below gage. Natural channel about 50 feet wide is constricted at bridge 

to 36 feet wide. Banks comparatively low; covered with underbrush; 

left bank subject to overflow at very high stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 5.85 feet at 

7 a. m. May 31 and 7 p. m. June 9 (discharge, 1,440 second-feet); minimum 

stage recorded, 2.20 feet at 8 a. m. November 30 (discharge, 74 second-feet). 

1908-1921: Maximum discharge recorded, 1,860 second-feet, April 22, 

1910; minimum discharge, 30 second-feet, November 20, 1914. Records 

obtained prior to 1914 incomplete.

ICE. Stage-discharge relation affected by ice every winter.

DIVERSIONS. Water stored in Strawberry Valley reservoir (capacity, 250,000 

acre-feet) about 40 miles above station, is diverted by means of a tunnel to 

the Spanish Fork drainage basin. Some water is also diverted from the 

upper end of Strawberry Valley to the basin of Provo River.

REGULATION. Since 1912 flow of river has been affected by operation of Strawberry Valley reservoir.

ACCURACY. Stage-discharge relation changed slightly during winter; affected 

by-ice December 7 to March 3. Rating curves well defined below 500 

second-feet and fairly well defined above. Gage read to half-tenths twice 

a day until August 4 and to hundredths thereafter. Daily discharge ascertained by applying mean daily gage height to rating table except for period 

when stage-discharge relation was affected by ice. For this period, discharge 

was estimated from weather records, observer's notes, and hydrographic 

comparison with Duchesne River at Duchesne and at Myton, and Lake 

Fork near Myton. Records good.

108 SURFACE WATER SUPPLY, 1921, PART IX.

UIWTA RIVER WEAR WE01A, UTAH.

LOCATION. About on line between sees. 25 and 26, T. 2 N., E. 2 W., Uinta 

special base and meridian, 800 feet above tailrace of Pole Creek power 

plant, IK miles above mouth of Pole Creek, and 9 miles north of Neola, 

Duchesne County.

DRAINAGE AREA. 181 square miles.

RECORDS AVAILABLE. July 30 to September 30, 1921.

GAGE. Stevens continuous recorder on left bank, supplemented by inside hook 

and outside vertical staff gages; inspected by Jed Timothy.

DISCHARGE MEASUREMENTS. Made from cable at gage or by wading. Measuring conditions exceptionally bad on account of rough channel.

CHANNEL AND CONTROL. Channel steep and rough. Bed composed of boulders 

and gravel. Banks fairly high and probably not subject to overflow unless 

channel changes, which may readily occur during high water. Gage height 

of zero flow at 0.25 foot as determined on August 2, 1921.

EXTREMES OP DISCHARGE. Not determined.

ICE. River freezes over every winter.

DIVERSIONS. None above station.

REGULATION. None.

ACCURACY. Rating curve for gage-height records thus far obtained is based on 

two discharge measurements made August 2 and October 3, 1922, and point 

of zero flow on August 2. It is well defined for range in stage occurring 

during period of records. Operation of water-stage recorder satisfactory. 

Daily discharge ascertained by applying to rating table mean daily gage 

height determined from recorder graph. Records good.

The following discharge measurement was made by W. E. Dickinson: 

August 2, 1921: Gage height, 2.53 feet; discharge, 420 second-feet.

Daily discharge, in second-feet, of Uinta River near Neola, Utah, for the period 

July 30 to Sept. SO, 1921.

GREEN RIVER BASIN. 109 

WHITEROCKS CREEK NEAR WHITEROCKS, UTAH.

LOCATION. In sec. 18, T. 2 N., R. 1 E., Uinta special base and meridian, 8 miles 

north of Whiterocks, Uinta County. United States Whiteroeks canal 

diverts from left side and Farm Creek canal from right side 2 miles below 

station.

DRAINAGE ABBA. 118 square miles.

RECORDS AVAILABLE. August 1 to September 30, 1921, at present site. November 8, 1917, to June 2, 1921, at a point about 2 miles downstream below 

diversion of United States Whiterocks canal and above Farm Creek canal. 

1899 to 1904 and 1907 to 1910 somewhere in vicinity of present site. Records 

are comparable.

GAGE. Stevens continuous water-stage recorder on left bank; installed August 

4, 1921; inspected by J. F. Wilkin. Also inside hook and outside .vertical 

enamel staff gages.

DISCHARGE MEASUREMENTS. Made by' wading or from cable a quarter of a 

mile above gage.

CHANNEL AND CONTROL. Narrow box canyon. Stream bed is steep and rough; 

composed of boulders and gravel. Channel is subject to change by erosion 

during high water.

EXTREMES OF DISCHARGE. Maximum stage during year not recorded, but 

maximum discharge occurred in June and probably exceeded 1,700 secondfeet. Minimum discharge, less than 14 second-feet in the winter. 

1918-1921: Maximum and minimum discharge occurred in 1921.

ICE. Stream freezes over each winter.

DIVERSIONS. After August 1, 1921, above all diversions. Prior to August 1, 

above all diversions except United States Whiterocks canal which diverts 

from left bank just above this station. Records of discharge of this canal 

for the irrigation season accompany records for this station.

REGULATION. None.

ACCURACY. Station destroyed by flood in June; rebuilt at present site in August. 

Stage-discharge relation at each site permanent for periods of record, except 

as affected by ice in winter. Rating curve for period October to May 

well defined below 800 second-feet; curve for August and September well 

defined. Operation of water-stage recorder satisfactory only during periods 

for which daily discharge is given continuously in table; weekly staff gage 

readings used for other periods. Daily discharge ascertained by applying 

to rating table mean daily gage height determined from recorder graph. 

Recorder not in operation August 1-3 and September 4-27. Staff gage 

read September 9, 14, and 22. Daily discharge for these periods estimated 

by hydrographic comparison with Uinta River near Neola. Monthly mean 

discharge estimated October to March from weather records, observer's 

notes, and interpolated between values obtained from weekly gage readings. 

Records fair.

Records of discharge of the United States Whiterocks canal for the irrigation 

season are published with this station to supplement the records of flow at the 

station prior to August 1,1921, as this was the only diversion in the Whiterocks 

Creek basin above this station. The records of daily discharge of this canal 

were furnished by C. C. Jacob, Federal Court water commissioner.

LOCATION. In sec. 36, T. 13 S., R. 9 E., at ford 300 feet west of Denver & Rio 

Grande Western Railroad main line at Spring Glenn, 1 mile above diversion 

dam of Price River Irrigation Co., 2 miles south of Helper, Carbon County, 

and 3 miles below Spring Creek.

DRAINAGE AREA. 530 square miles (measured on topographic maps).

RECORDS AVAILABLE. February 21, 1904, to September 30, 1921.

GAGE. Vertical staff on left bank; installed July 16. 1907; read by D. S. 

Rowley. For gages used prior to July 16, 1907, see Water-Supply Paper 479.

DISCHARGE MEASUREMENTS. Made by wading,

CHANNEL AND CONTROL. Bed of stream composed of gravel and fine sand. A 

riffle immediately below ford shifts occasionally during floods.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 5.12 feet on 

May 30 (discharge, 1,950 second-feet). Unrecorded floods of short duration were much higher on August 1, 22, 23, 25, 30, and 31. Minimum 

discharge not determined.

1904-1921: Summer floods occur nearly every year and often greatly 

exceed any recorded stage. Maximum stage recorded for which discharge 

was determined," 8.43 feet at 9 p. m. June 25, 1917, determined by leveling 

from hub set at high-water mark (discharge determined from extension of 

rating curve, 8,500 second-feet). Minimum stage recorded, 3.1 feet (old 

chain gage) during December, 1905, and January, 1906 (discharge, 4 secondfeet).
112 SURFACE WATER SUPPLY, 1921, PART IX.

ICE. Stage-discharge relation affected by ice for short periods nearly every 

winter.

DIVERSIONS. Main diversions from Price River are below station.

REGULATION. Flow of river was affected by storage at Mammoth reservoir 

(capacity about 11,000 acre-feet) of Price Irrigation Co. on Gooseberry 

Fork, 40 miles above station, until June 24, 1917, when dam broke.

ACCURACY. Stage-discharge relation changed during winter and again during 

spring high water in early part of June; affected by ice December to February. Rating curves fairly well defined below 400 second-feet; extended 

above.\ Gage read to hundredths once a day and oftener during periods 

of rapidly changing stage. Daily discharge ascertained by applying mean 

daily gage height to rating table. Discharge for period of ice effect estimated from one meter measurement, temperature records, and observer's 

notes on ice conditions. Records fair. ^

FISH CREEK NEAR SCOFIEID, UTAH.

LOCATION. In sec. 10, T. 12 S., R. 7 E., three-quarters of a mile above railroad 

siding at Hale, 5 miles northeast of Scofield, Carbon County, and 10 miles 

above point where Fish Creek and White River unite to form Price River.

DRAINAGE AREA. 163 square miles (measured on United States Forest Service 

map, 1920).

RECORDS AVAILABLE. November 17, 1917, to September 30, 1921, when 

station was discontinued; fragmentary.

GAGE. Stevens eight-day water-stage recorder on left bank 85 feet below 

railroad bridge; installed November 17, 1917; inspected by J. E. Jensen. 

Also inside and outside vertical enamel staff gages.

DISCHARGE MEASUREMENTS. Made by wading, from railroad bridge near gag©, 

or from road bridge 1 mile upstream.

CHANNEL AND CONTROL. One channel at all stages. Right bank is a high rock 

cliff; left bank lower but probably not subject to overflow. Railroad embankment a few feet back from left bank can not be overflowed. Stream 

bed gravel and sand. Riffle a short distance below gage.

EXTREMES OF DISCHARGE. Not determined for current year.

1918-1921: Maximum stage recorded, 10.4 feet about May 24, 1920, from 

high-water mark in gage house (discharge about 1,000 second-feet). Minimum discharge not determined.

ICE. Stream freezes over each winter

DIVERSIONS. No information. Probably some small diversions for irrigation 

above the station.

REGULATION. None since the failure on June 24, 1917, of the Mammoth reservoir 

dam on Gooseberry Fork, a tributary to Fish Creek. This reservoir had a 

capacity of about 10,000 acre-feet and was used by the Price River Irrigation 

Co. to store water for irrigation near Price, Utah.

ACCURACY. Stage-discharge relation changed slightly during period, December 

to June, when no record was obtained. Rating curves well defined below 

400 second-feet. Operation of water-stage recorder satisfactory only for 

periods of discharge given in daily-discharge table. Daily discharge ascertained by applying to rating table the mean daily gage height determined 

from recorder graph. Discharge not determined December 16 to June 24 

and July 3-27. Records given are good.

HUNTINGTON CREEK NEAR CASTLEDALE, UTAH.

LOCATION. In sec. 33, T. 18 S., R. 9 E., half a mile below bridge on road to 

Green River, 5 miles above mouth of Cottonwood Creek, and 6 miles east 

of Castledale, Emery County.

DRAINAGE AREA. 325 square miles (measured on topographic maps).

RECORDS AVAILABLE. May 12, 1911, to August 13, 1921, when station was 

discontinued; fragmentary.

GAGE. Stevens continuous water-stage recorder on right bank; inspected by 

Rex Peterson; installed May 2, 1913, at same datum as vertical staff gage 

which it replaced.

DISCHARGE MEASUREMENTS. Made by wading or from cable just below gage.

CHANNEL AND CONTROL. Bed composed of sand and small gravel. Banks 

fairly high; subject to erosion but not to overflow. Original artificial control 

which was formed by 2 by 12 inch planks, placed edgewise in a trench and 

anchored to pipes driven into stream bed, has been obliterated.
GREEN RIVER BASIN. 117

EXTREMES OP DISCHARGE. Maximum stage during year from water-stage 

recorder, 7.45 feet at 9 a. m. June 10 (discharge, 1,000 second-feet). Floods 

in July and August probably exceeded this. Discharge probably less than10 second-feet at times during the winter.

1911-1921: Maximum stage recorded, 11.3 feet, September 8, 1913, when 

dam above station broke (discharge estimated, 1,750 second-feet). Minimum stage recorded, 0.95 foot, September 10,1915 (discharge, 2.5 second-feet).

ICE. Stage-discharge relation seriously affected by ice each winter.

DIVERSIONS. The station is below all diversions in Castle Valley.

REGULATION. Flow affected by irrigation in Huntington district.

ACCURACY. Stage-discharge relation changed during high water about June 10 

and changed radically during floods in August; affected by ice December 

1 to March 10. Rating curves fairly well defined below 200 second-feet 

and extended above parallel to 1914 curve. Operation of water-stage 

recorder not satisfactory owing to silting up of stilling well during frequent 

periods. No record obtained during winter. Daily discharge ascertained 

by applying to rating table mean daily gage height determined from recorder 

graph. Discharge interpolated or estimated for a few short periods of no 

gage-height record. Records given are good.

EXTREMES OF DISCHARGE. Maximum stage recorded during period October 1, 

1920, to July 16, 1921, 5.9 feet June 10 (discharge, 1,880 second-feet). 

Short-time discharge of sudden floods in July, August, and September 

greatly exceeded this. Minimum discharge probably less than 15 secondfeet in winter.

1909-1921: Maximum discharge recorded, 1,980 second-feet, September 

7, 1913; minimum discharge recorded, 5 second-feet, September 21, 1910.

ICE. Stage-discharge relation affected by ice every winter.

DIVERSIONS. Two or three small ditches divert water above station but all 

the main ditches take out below.

REGULATION. None.

ACCURACY. Stage-discharge relation changed slightly about June 10, during 

spring high water, and changed considerably several times during July, 

August, and September during period of sudden floods; affected by ice 

December 1 to February 24. Rating curves fairly well defined below 800 

second-feet and extended above. No rating could be determined for the 

period July 17 to September 30. Gage read to tenths four to six times a week. 

Daily discharge ascertained by applying daily gage height to rating table 

and by interpolation for days when gage was not read, except for period 

when stage-discharge relation was affected by ice. For this period discharge was estimated from observer's notes, weather records, and one discharge measurement. Discharge not determined July 17 ifco September 

30. Records good.

120 SURFACE WATER SUPPLY, 1921, PART IX.

FERRON CREEK (UPPER STATION) NEAR PERRON, UTAH.

LOCATION. In SW. J^ sec. 1, T. 20 S., R. 6 E., a quarter of a mile below house 

at Peterson ranch, 1J^ miles above grist mill, and 5 miles northwest of 

Ferron, Emery County.

DRAINAGE AREA. 140 square miles (measured on United States Forest Service 

map, 1920).

.RECORDS AVAILABLE. May 6, 1911, to September 30, 1921.

GAGE. Inclined staff on right bank; read by Joseph Peterson; installed September 13, 1911. Datum lowered 1.00 foot September 4, 1919.

DISCHARGE MEASUREMENTS. Made by wading or from cable 15 feet upstream 

from gage.

CHANNEL AND CONTROL. Banks high and not subject to overflow. Bed composed of sand and gravel. Current swift and has tendency to cut channel 

deeper. Stage of zero flow at gage height, 0.5 foot as determined August 

12, 1921.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 6.6 feet at 

9 p. m. June 9 (discharge, 1,290 second-feet); minimum stage recorded, 

0.90 foot on November 15 and March 27 (discharge, 8 second-feet).

1911-1921: Maximum stage recorded, 10.0 feet at 3 p. m. July 25, 1920 

(discharge probably 2,000 second-feet); minimum discharge recorded, 

1 second-foot, March 22 and 23, 1912.

ICE. Stage-discharge relation seriously affected by ice every winter.

DIVERSIONS. Above all diversions except a small ditch for the Peterson ranch.

REGULATION. None.

ACCURACY. Stage-discharge relation changed during high water May 26 to 

June 8. From November 28 to March 5 there was ice in the creek but 

during a large part of January and February Ice was supported clear of the 

water by the banks of the narrow channel. Rating curves fairly well 

defined below 400 second-feet and extended above. Gage read to hundredths 

twice a day April to September and once a day October to March. Not 

read November 23, January 17, March 19, and September 26 and 28. During thunder-storm period in July and August high-water marks were noted. 

Daily discharge ascertained by applying mean daily gage height to rating 

table except for days of large fluctuation and periods when stage-discharge 

relation was affected by ice. For these periods discharge was estimated 

from one meter measurement, observer's notes, recorded gage heights, and 

weather records. Discharge interpolated for days when gage was not read. 

Records good.

LITTLE COLORADO RIVER BASIN. 

ZUWI RIVER AT BIACK ROCK, If. MEX.

LOCATION. At reservoir of Zuni Indian Reservation at Black Rock, McKinley 

County. Rio de Los Nutrias, nearest large tributary, enters from north 4 

miles above.

DRAINAGE AREA. About 660 square miles.

RECORDS AVAILABLE. Yearly flow July 1, 1903, to June 30, 1905; July 1, 1908, 

to June 30, 1910. Monthly flow October 1, 1910, to September 30, 1921. 

Record since July 1, 1908, shows inflow into reservoir.

METHOD OF COLLECTING DATA. From July 1, 1903, to June 30, 1905, records 

were obtained by the ordinary stream-gaging methods. Reservoir -completed in 1908. Record beginning July 1, 1908, obtained by means of gage 

in reservoir and capacity curve for reservoir, quantity of water released from 

the reservoir during the periods of inflow being taken into consideration.

FLOODS. Channel dry greater part of the year below point where it leaves 

mountains, but stream is subject to sudden floods of considerable volume 

and usually of short duration.

DIVERSIONS. Reservoir at Ramah, about 18 miles above station, capacity of 

which is given as 4,240 acre-feet, is used to irrigate about 1,150 acres in T. 

11 N., R. 16 W. There are other small ponds or reservoirs in drainage area.

VIRGIN RIVER BASIN. 

VIRGIN RIVER AT VIRGIN, UTAH.

LbcATioN. In. NW. M sec. 27 or NE. M sec. 28, T. 41 S., R. 12 W., a few 

hundred feet above point where river enters a steep, narrow gorge, and 

three-quarters of a mile west of Virgin, Washington County. Station 

replaces one maintained prior to February, 1915, half a mile above Virgin 

and gives practically same record of flow.

DRAINAGE AREA. 1,010 square miles (measured on topographic maps).

RECORDS AVAILABLE. April 18, 1909, to September 30, 1921.

GAGE. Chain gage on the right bank near the lower end of sandstone bluff. 

Installed February 1, 1915; read by Lawrence Earl.

DISCHARGE MEASUREMENTS. Made by wading below the gage, except during 

high water, when old cable above Virgin must be used.
VIRGIN EIVEE BASIN. 123

CHANNEL AND CONTROL. Bed consists of sand and gravel. Right bank high; 

left bank low and is overflowed. One channel at all stages. Principal control is a grayel bar a short distance below the gage; shifting.

EXTREMES OF DISCHARGE. Not determined for current year.

1909-1918: Maximum stage recorded, 11.6 feet at upper station October 

27, 1912 (discharge estimated, 12,000 second-feet). The flood of August 

31, 1909, probably equaled or exceeded this flow. Minimum discharge, 24 

second-feet, July 1, 2, 4, and 5, 1909.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. Above ail important diversions.

RE GUL ATION. None.

ACCURACY. Stage-discharge relation variable. Gage read to hundredths four 

or five times a week. Occasional floods of short duration occurred which 

do not appear in recorded gage heights. Rating curves not sufficiently well 

defined to warrant publication of daily discharge. Monthly discharge is 

believed to be accurate enough for general studies.

11582 25t WSP 529 9
SUBFACE WATER SUPPLY, 1921, PART IX.

SANTA CLARA GREEK NEAR CENTRA!,, UTAH.

LOCATION. In sec. 11, T. 39 S., R. 16 W., j'ust above bridge at R. H. Hunt's 

ranch, 1 mile southeast of Central, Washington County, on road to Pine 

Valley. Hunt's spring, which has fairly constant discharge of about 3 

second-feet, enters 10 feet below gage.

DRAINAGE AREA. 84 square miles (measured on topographic maps).

RECORDS AVAILABLE. April 21, 1909, to September 30, 1921.

GAGE. Vertical staff nailed to cottonwood tree on left bank about 20 feet above 

the ford; read by Mrs. R. H. Hunt. Datum of gage was raised 0.45 foot 

on January 20, 1910, 2.00 feet on February 22, 1916, and lowered 1.00 foot 

on August 12, 1918.

DISCHARGE MEASUREMENTS. Made by wading or from footbridge at gage.

CHANNEL AND CONTROL. Stream bed consists of gravel arid sand. Banks 

fairly high but may be overflowed at extreme stage; one channel at all 

staged. A riffle formed by small boulders 100 feet below gage is fairly 

permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 1.55 feet oa 

May 30 (discharge, 52 second-feet); minimum stage recorded, 1.00 foot on 

February <J8 (discharge, 9 second-feet).

1909-1921: Maximum stage recorded, 5.00 feet at 11 a. m. October 6,, 

1916 (discharge, 1,450 second-feet); minimum stage recorded, 0.82 foot on 

January 8, 1920 (discharge, 4 second-feet).

ICE. Stage-discharge relation seldom affected by ice.

DIVERSIONS. The New Castle Reclamation Co. has constructed a reservoir on 

Grass Valley Creek with a capacity of 23,000 acre-feet. Water is diverted 

into the reservoir from Santa Clara Creek above town of Pine Valley and 

released into tunnel through rim of the Great Basin for Irrigation of lands 

outside the Colorado River basin. The Central canal diverts water about 

2 miles above station for irrigation of lands near Central. This canal has 

been measured when it was carrying 16 second-feet.

REGULATION. Fksv affected by the diversions and storage above.

ACCURACY. Stage-discharge relation changed by sudden freshet on March 13; 

constant before and after that date. No ice during current year. Bating 

curves well defined below 250 second-feet. Gage read to hundredth? once 

a day with frequent omissions of one to two. days. Daily discharge ascer-

; tained by applying daily gage height to rating table and interpolating 

discharge for days when gage was not read. Records good.

126 SUEFACE WATER SUPPLY, 1921, PAET IX.

GILA RIVER BASIN. 

GILA RIVER NEAR SOLOMONVILLE, ARIZ.

LOCATION. In NE. M sec. 31., T. 6 S., R. 28 E., 1 mile below intake of Brown 

canal and 10 miles above Solomonville, Graham County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 21,1914, to September 30,1921.

GAGE. Stevens continuous water-stage recorder on left bank, directly opposite 

J. W. Earven's ranch; inspected by J. W. Earven.

DISCHARGE MEASUREMENTS. Made by cable at gage or by wading.

CHANNEL AND CONTROL. Bed composed of gravel, sand, and silt; shifts considerably during rises.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 7.55 feet at 

10.30 p. m. August 21 (discharge, 15,700 second-feet); minimum stage, 

0.75 foot June 30 and July 1 (discharge, 60 second-feet).

1914-1921: Maximum stage, determined from flood marks on gage, 14.0 

feet January 19, 1916 (discharge, about 100,000 second-feet from extension 

of rating curve); minimum discharge, that of June 30 and July 1, 1921.

DIVERSIONS. Brown canal, which irrigates a few hundred acres on the north 

side of the river, heads 1 mile above this station, maximum capacity about 

25 second-feet. About 8,000 acres are irrigated from Gila River above the 

gaging'station, principally in Duncan Valley.

ACCURACY. Stage-discharge fairly permanent between rises. 27 measurements made during the year defined rating curves used as follows: October 

1-15, fairly well defined below 1,000 second-feet; October 16 to November 

30, indirect method for shifting control used; December 1 to February 15, 

well defined below 250 second-feet; February 17 to March 1, indirect 

method for shifting control used; March 2 to August 21, well defined; 

August 22 to September 25, well defined; September 26-30, well defined. 

Water-stage recorder checked on days when measurements were made, and 

at other times by J. W. Earven. The operation of the recorder was satisfactory throughout the year except for short periods when clock trouble 

occurred. The observer's staff gage readings were used during these missing 

periods as follows: December 20-23, January 13-15, 27, May 23, 25, July 5, 

August 2-6. No records December 16-19, January 12, 24-26, May 24, 

July 4, 6, 31, August 1, 4, and 5. Discharge interpolated for these periods. 

Daily discharge ascertained by applying mean daily gage height to rating 

table. Records good.

128 SURFACE WATER SUPPLY, 1921, PART IX.

Stevens continuous water-stage recorder on left bank; inspected by 

Tecora Ketchayan and Harvey Ford.

DISCHARGE MEASUREMENTS. Made from cable 1 mile above gage or by wading,

CHANNEL AND CONTROL. Bed consists of sand, gravel, and boulders; shifting. 

Control afforded by rapids over heavy boulders just below gage. Channel 

at measuring cable, 1 mile upstream from gage, is wide and shallow; fills 

with quicksand at certain stages. Banks not subject to overflow. Poor 

for measurements under 1,000 second-feet. At a point 400 feet above gage 

river makes abrupt entry into box canyon filled with gravel and boulders. 

At low stages gravel bar is formed on left bank around point of rock at gage 

location, necessitating the maintenance of a ditch from channel to gage 

well. This low-water condition develops a changeable control, and frequent 

inspection of well and ditch, as well as frequent measurements, are required 

to obtain the stage-discharge relation under these control conditions.

EXTREMES OP DISCHARGE. 'Maximum stage during year from water-stage 

recorder, 9.9 feet at 4 p. m., July 31 (discharge, 12,800 second-feet); minimum 

stage 0.75 foot, June 15 and June 27 to July 2 (discharge, 0.2 second-foot). 

1914-1921: Maximum stage 25.5 feet, January 20, 1916 (discharge, from 

extension of rating curve, about 92,000 second-feet); minimum stage dry 

June 28 to July 1, 1919.

DIVERSIONS. Water for irrigating about 24,000 acres is diverted from river 

above station by Safford Valley. About 8,000 acres is irrigated from this 

stream above station near Solomonville.

ACCURACY. Stage-discharge relation changes on account of changes in ditch 

to gage during low water, and changes in gravel bar about gage at other 

 stages. Standard rating curve fairly well denned between 1,000 and 14,000 

second-feet, and poorly defined above. Below 1,000 second-feet, three 

rating curves covering different periods of time, dependent upon changes in 

ditch and control, and discharge measurements have been used. Waterstage recorder checked weekly, or semiweekly, during year by observer's 

staff gage readings, read to half-tenths. The reliability of the low-flow 

records during the year has been somewhat affected by the low-water channel 

conditions. See "Channel and control." Comparison has been made with 

records obtained on Gila River near Solomonville and at Kelvin. The 

operation of water-stage recorder was reasonably satisfactory except when 

influenced by poor channel conditions at low water, as indicated in footnote to daily discharge table. Daily discharge ascertained by applying 

mean daily gage height to rating table, except for missing periods as indicated 

in footnote to daily-discharge table. Records fair.

ending Sept. 30, 1921.

130 SURFACE WATER SUPPLY, 1921, PART IX.

GILA RIVER AT KELVIN, ARIZ.

LOCATION. In sec. 12, T. 4'S., R. 13 E., 1,000 feet 1 below mouth of Mineral 

Creek, one-fourth mile below concrete highway bridge, 1 mile below Kelvin,2 

Final County, and 25 miles above Florence.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. January 26, 1911, to September 30, 1921.

GAGE. Stevens continuous water-stage recorder installed June 15, 1914, on left 

bank half a mile above original gage and referred to new datum. Original 

gage, an inclined staff fastened to basalt ledge on right bank opposite observer's house. For description of various gages used, see Water-Supply 

Paper 459.

DISCHARGE MEASUREMENTS. Made from highway bridge one-fourth mile 

above gage or by wading.

CHANNEL AND CONTROL. Bed composed of sand, gravel, and silt; continually 

shifting. No well-defined control.

EXTREMES OF DISCHARGE. Maximum stage during year from staff reading, 8 

feet on August 22 (discharge, 15,500 second-feet); minimum stage from 

water-stage recorder, 1.6 feet June 18 to July 4 (discharge, 1.0 second-foot); 

1911-1921: Maximum stage 19.5 feet about noon January 20, 1916, 

determined from flood marks (discharge, from extension of rating curve, 

about 93,000 second-feet); no flow June 29 to July 11, 1913.

DIVERSIONS. About 24,000 acres is irrigated from this stream between this 

station and Solomonville, and about 8,000 acres above Solomonville.

ACCURACY. Stage-discharge relation continually changing. Standard rating 

curve fairly well defined below 30,000 second-feet, poorly defined above* 

Rating curves for short periods between rises used. Water-stage recorder 

checked weekly during year by observer's staff gage readings read to hundredths. Operation of water-stage recorder satisfactory except for periods 

indicated in footnote to daily-discharge table. Daily discharge ascertained 

by applying mean daily gage height to rating table except for February 

9-15, when indirect method for shifting control was used; and for missing 

periods as indicated in footnote to daily-discharge table. Records good.

ARAVAIPA CREEK HEAR FELDMAN, ARIZ?.

LOCATION. In sec. 9, T. 7 S., R. 16 E., 2 miles east of Feldman, Final County, 

1,200 feet above junction of Aravaipa Creek and San Pedro River, and "at 

concrete highway dip.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 21, 1919, to September 30, 1921, when station was 

discontinued.

GAGE. Painted on downstream side of concrete dip from 1.0 to 3.0 feet and from 

3.0 to 8.0 feet on county vertical pipes at either end of dip; gage read by 

Delia E. Barker.

DISCHARGE MEASUREMENTS. Made by wading up to 1,000 second-feet; above 

1,000 second-feet, by floats.

CHANNEL AND CONTROL. Bed consists of gravel and boulders; shifting. Control afforded by concrete dip, affected by deposits of gravel and sand. Banks 

not subje'ct to overflow.

EXTREMES OP DISCHARGE. Maximum stage during year, 5.0 feet on July 31 

(discharge, 12,600 second-feet); minimum stage, zero flow each month.

1919-1921: Maximum stage 6.3 feet on August 2, 1919 (discharge, 20,000 

second-feet); minimum stage, zero flow each month.

ICE. None.

DIVERSIONS. Approximately 2,000 acres irrigated above gage.

REGULATION. None.

ACCURACY. Stage-discharge relation changes on account of gravel deposits on 

dip and shifting of low-water channel. Curves for short periods used for 

low water. Standard curve poorly defined above 500 second-feet. Gage 

read to quarter-tenths once daily and oftener during rises. Daily discharge 

ascertained by applying mean daily gage height to rating table or by hourly 

discharges on rapidly changing stages. Records poor on account of changing 

control and lack of measuring equipment.

SAffTA CRUZ BIVEB AT TUCSOIT, ABIZ.

LOCATION. In see. 14, T. 14 S., R. 13 E., at Congress Street Bridge at Tueson, 

Pima County, 7 miles above Rillito Creek.

RECORDS AVAILABLE. October 15, 1905, to September 30, 1921.

DEAINAGE ABEA. Not measured.

GAGE. Staff gages painted on downstream side of each bridge abutment. 

Original gage was painted on bridge pier on left bank. During 1911 and 

up to September 30, 1912, gage heights were observed from temporary 

staff or by measuring to the water surface from a reference point on bridge. 

October 1, 1912, to July 7, 1913, a chain gage installed on bridge was used.. 

Original datum was maintained until November 22, 1913, when it was 

lowered 2 feet. From December 12, 1914, to September 7, 1916, gage 

heights were obtained from a reference point to 16.73 feet above datum. 

During summer of 1916 a new bridge was constructed and a staff gage was 

installed September 7, on one side of the piers at a different datum. Since 

then, additional painted gages, set to the same datum, have been used to 

facilitate observations when river flows in several channels past the bridge. 

Observer, J. O. Kenny.

DISCHARGE MEASUEEMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Bed composed of sand; channel wide and shallow; 

shifts badly at all stages. High water of August 2, 1921, washed out bank 

protection on right bank upstream from bridge and permitted the river to 

encroach on road embankment. The direction of approach of river to 

bridge measuring section was considerably altered. Temporary revetment 

was later placed on right bank to protect bank from further cutting.
4HLA HIVEK BASIN. 161

EXTREMES OP DISCHARGE. Maximum discharge recorded during year, 4,000 

second-feet, about 7 a. m. August 1, from hydrograph; minimum flow, 

zero most of year.

1905-1921: Maximum stage recorded, 9.8 feet, December 24, 1914 (discharge, approximately 9,000 second-feet). Stream dry most of each year 

at this point;

DIVERSIONS. Diversions above the station for irrigation, amounts unknown.

ACCURACY. Stage-discharge relation not permanent. Loose sand channel and 

control continually changing. Gage read to tenths several times daily 

during flow periods. Daily discharge computed by indirect methods, and 

hydrographs prepared for high-water periods. Records fair. During part 

of winter for a period of one or two months usually from 2 to 6 second-feet 

flows past the gage which is not measured. This is waste from irrigation 

ditch that enters the river about one-quarter mile upstream.

 COOPERATION. Daily-discharge record furnished by University of Arizona 

through Prof. G. E. P. Smith, irrigation.engineer.

RIILITO CREEK NEAR TUCSON. ARIZ.

LOCATION. In sec. 23, T. 13 S., R. 13 E., at highway bridge on Oracle road, 4 

miles above confluence with Santa Cruz River and 4 miles north of Tucson, 

Pima County.

DRAINAGE AKEA. Not measured.

RECOKDS AVAILABLE. January 12, 1911, to September 30, 1921 (incomplete).

GAGE. Staff gage painted on downstream side of right abutment, referred to as 

gage A. Additional painted gages as needed, set to same datum, are located 

on the several piers of the highway bridge to facilitate observations when 

river flows in several channels past the bridge. These are designated as 

gages B, C, D, E, and F, starting from first pier from right abutment. Gage 

E was installed January 19, 1920; gage F was installed in the fall of 1921 

after the pier was rebuilt. A Richard Freres water-stage recorder attached 

to right abutment of bridge was used part of the time prior to July 21; 1916, 

when it was destroyed. Observer, Morgan Mason.

DISCHAKGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTKOL. Bed composed of sand which is constantly shifting. 

On July 31, 1921, at 5 p. m. the fifth pier from the right abutment (first 

pier from left abutment) became undermined and washed out allowing 

two bridge spans to drop into the channel. Low-water flows passed through 

that opening and in a narrow channel parallel to the bridge through the last 

span. On about August 28, 1921, bridge repair operations again changed 

the low-water channel. Repairs were completed about October 17, 1921, 

leaving a hill of sand some 16 feet high immediately downstream from the 

bridge.

EXTKEMES OP DISCHAKGE. Maximum discharge recorded during year, midnight, July 31, 16,000 second-feet, from hydrograph. Stream dry greater 

part of year.

1911-1921: Maximum discharge recorded, as given above; maximum 

mean daily discharge, about 16,000 second-feet on December 23, 1914 (no 

record of discharge at peak of flood). Stream dry greater part of each year.

DIVERSIONS. Flood water is diverted for irrigation above station, amount' 

unknown.

ACCURACY. Stage-discharge relation not permanent. Loose sand channel and 

control continually changing. Gage read to tenths several times daily during 

flow periods. Daily discharge computed by indirect methods and hydrographs. Many of the small flows that did not reach gage were estimated. 

Records poor.

COOPERATION. Discharge measurements and record of daily discharge furnished by University of Arizona, Prof. G. E. P. Smith, irrigation engineer.

SALT RIVER NEAR ROOSEVELT, ARIZ.

LOCATION. At diversion dam for power canal, 10 miles above upper end of

Roosevelt reservoir and 20 miles east of Roosevelt, Gila County. 

DBAINAGE AKEA. 1,222 square miles (measured by United States Bureau of

Reclamation). 

RJBCOBDS AVAILABLE. October 1, 1913, to September 30, 1921 (including all

water diverted for the development of power but not flow of Tonto Creek);

February 7, 1901, to December 9, 1907, at site of Roosevelt dam (including

flow of Tonto Creek).

1910-1913: Discharge at Roosevelt dam computed from records of flow

into and out of the reservoir (representing natural flow of Salt River, including

Tonto Creek and water diverted for the development of power). 

11582 25f WSP 529 12
164 SURFACE WATER SUPPLY, 1921, PART IX.

GAGE. Principal gage is vertical staff on left bank, bolted to concrete wall.at 

head of canal. Temporary gages are used from time to time on account of 

the channel shifting away from the main gage.

DISCHARGE MEASUREMENTS. Made from cable at dam site or by wading near 

dam site. Prior to January 19, 1916, when the dam was destroyed by flood, 

low-water measurements were made by wading below the dam. Above 

wading stage, discharge was determined from elevation of water surface in 

reservoir, taking into account known outflow and computed inflow from other 

sources besides Salt River.

CHANNEL AND CONTROL. Shifting sand and gravel. Prior to its destruction by 

flood on January 19, 1916, the dam formed a permanent control.

EXTREMES OF DISCHARGE. Maximum mean daily discharge during the year,

12,000 second-feet, August 22; minimum discharge, 152 second-feet, July 4.

1913-1921: Maximum mean daily discharge, 79,200 second-feet January

15,1916; minimum discharge, 152 second-feet September 25,1918, and July 4,

1921.

DIVERSIONS. None.

ACCURACY. Discharge measurements are made nearly every day when discharge 

is less than about 3,000 second-feet, and the results should be excellent. For 

flow greater than 3,000 second-feet there are no facilities for making discharge 

measurements. Discharge determined from extension of rating curve and 

study of reservoir contents, anti results are subject to considerable error.

COOPERATION. Daily-discharge records furnished by Salt River Valley Water 

Users' Association.

NORTH FORK OF WHITE RIVER AT WHITERIVER, ARIZ.

LOCATION. At power plant half a mile from Fort Apache Indian School at 

v Whiteriver, Navajo County, 2J^ miles above junction of north and east 

forks of White River.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. October 1, 1916, to September 30, 1921 (incomplete).

GAGE. Vertical staff on right bank just below tailrace of power plant; after 

June 6 an inclined staff 140 feet below power plant (datum lowered 3.0 feet); 

read by Chester Gate wood.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Bed composed of sand and gravel; shifts during high 

water. Control is of gravel and boulders.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 7.0 feet in 

afternoon of August 4 and 5 (discharge, 2,700 second-feet); minimum discharge, 10 second-feet June 22 and 27.

1916-1921: Maximum stage recorded, 7 feet during February, 1920 (discharge, not determined); minimum discharge, 10 second-feet June 22 and 27, 

1921.

ICE. Stage-discharge relation probably not seriously affected by ice.

DIVERSIONS. Water diverted for power development and returned to river above

REGULATION. Slight fluctuation may occasionally be caused by operation of 

power plant just above gage.

ACCURACY. Stage-discharge relation fairly permanent. Rating curves poorly 

denned. Gage read to quarter-tenths twice daily. Daily discharge ascertained by applying mean daily gage height to rating table except for periods 

December 17-29, April 1, 2, 4-12, 17, May 21-23, when discharge was interpolated, and January 19 to March 31, when no record was obtained.

172 SURFACE WATER SUPPLY, 1921, PART IX.

AGUA FRIA RIVER NEAR GLENDALE, ARIZ.

LOCATION. In sec. 28, T. .6 N., R. 1 E., at uncompleted masonry diversion dam 

of Beardsley irrigation project at Camp Dyer, 4 miles below mouth of Castle 

Creek and 22 miles northwest of Glendale, Maricopa County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. November 10, 1910, to September 30, 1921. <:

GAGE. Staff gage fastened to damaged stilling well at same datum on right 

bank at upstream face of dam; read by Will Benson. (For record of earliey 

gages used see Water-Supply Paper 479, p. 179.)

DISCHARGE MEASUREMENTS. Made from cable about one-third of a mile below 

gage or by wading. , . . i

CHANNEL AND CONTROL. Channel composed of gravel and shifting sand. 

Principal control is formed by the unfinished portion of the masonry diversion dam and ledge on which it is built. This dam has a large gap or opening 

near the right bank through which the low and medium flow passes, a scour 

gate opening, 4 feet by 7^ feet, in the base near the left bank through which 

flow from the left channel passes at higher stages, and another gap or opening 

near the left bank that carries flow at still higher stages. At extreme high 

stages the stream flows over the entire broad crest of the dani, which is at 

elevation 28.2 feet on the gage. Sand fills in and scours out of the crevices 

in the right gap of the dam continually with each rise in the river. The 

stage-discharge relation, therefore, is not permanent.

EXTREMES OP DISCHARGE. Maximum stage recorded during the year, 15.6 

feet at 6 p. m. July 31; minimum stage, 2.75 feet August 12 and 13.

1910-1921: Maximum stage, 33, feet November 27, 1919, determined 

from flood marks (discharge, about 105,000 second-feet from extension of 

rating curve); minimum discharge, 0.6 second-foot September 24 to 26, 1919.

DIVERSIONS. Water is diverted above gage for irrigating two or three small 

ranches; amount not known.

ACCURACY. No daily discharges computed, as base data was insufficient. Gageheight record good. ,
