SURFACE WATER SUPPLY OF COLORADO RIVER

BASIN, 1918.

AUTHORIZATION AND SCOPE OF WORK.

This volume is one of a series of 14 reports presenting results of 

measurements of flow made on streams in the United States during 

the year ending September 30, 1918.

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 30, 1895-1919.

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 pages 5 and 6.

Measurements of stream flow have been made at about 4,510 points 

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

Hawaiian Islands. In July, 1918, 1,180 gaging stations were being

l

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 OF TERMS.

The volume of water flowing in a stream the "run-off" or "discharge" is expressed in varipus 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 secondfeet 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, and acre-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 depth 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 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.

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

gage the gage height to which the water surface of the stream 

would fall if there were no flow.

EXPLANATION OF DATA.

The data presented in this report cover the year beginning October 

1,1917, and ending September 30,1918. 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 or chain gage or from a water-stage 

recorder that gives a continuous record of the fluctuations. Measurements of discharge are made with a current meter. (See Pis. I and II.) 

The general methods are outlined in standard textbooks on the 

measurement of river discharge.

From the discharge measurements rating tables are prepared that 

give the discharge for any stage, and these rating tables, when applied 

to the gage heights give the discharge from which the daily, 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 results 

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 heights and results 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 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 fluctuations 

the discharge obtained from the rating table and the mean daily 

gage height may not be the true mean discharge for the day. If
4 SURFACE WATER SUPPLY, 1918, PART IX.

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 using 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 for each second during the month. On this 

average flow computations recorded in the remaining columns, which 

are defined on page 2, are based.

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 or footnotes added to 

to the tables 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 heights to the 

rating table to obtain the daily discharge. 1

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 run-off in inches, may 

be subject to gross errors caused by the inclusion of large noncontributing districts in the measured drainage area, 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 stations

on streams draining areas in which the annual rainfall is less than 20 

inches. All figures representing "second-feet per square mile" and 

"run-off in inches" previously published by the Survey should be 

used with caution because of possible inherent sources of error not 

known to the Survey.

The table of monthly discharge gives only a general idea of the 

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, however, that 

the observations in each succeeding year may be expected to throw 

new light on data previously published.

GREEN RIVER AT LITTLE VALLEY, NEAR 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. 

DRAINAGE AREA. 41,000 square miles. 

RECORDS AVAILABLE. December 18,1910, to September 30,1918. Records obtained

at Green River (known also as Elgin or Blake) from 1894 to 1899 and 1905 to 1911

12 SUKFACE WATER SUPPLY, 1918, PART IX.

GAGE. Stevens continuous water-stage recorder replaced a Friez water-stage recorder on left bank about a mile above old ferry cable on December 16, 1917; 

inspected by R. C. Wheeler. Various gages at cable were in use from December 

18, 1910, to November 6, 1914, when Friez recorder was installed. The records 

at Green River were obtained from chain gage at Denver & Rio Grande Railroad bridge until December 2, 1910, when gage was moved 200 feet upstream to 

new highway bridge.

DISCHARGE MEASUREMENTS. Made from car on ferry cable.

CHANNEL AND CONTROL. Bed composed of gravel and sand. Principal control 

probably about two-thirds of a mile below the gage; apparently fairly permanent.

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

10.47 feet at 3 a. m. June 26 (discharge, 43,700 second-feet); minimum stage, from 

water-stage recorder, 0.03 foot at noon January 14 (discharge, 1,100 second-feet). 

1894-1899, 1905-1918: Maximum discharge recorded, 68,800 second-feet, May 

29, 1897; minimum stage recorded, 0.35 foot at 8 a. m. December 21, 1915 

(discharge, 875 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. Stage-discharge relation permanent; probably not affected by ice during 

year. Rating curve well defined between 800 and 70,000 second-feet. Operation of water-stage recorder satisfactory except as indicated in footnote to table of 

daily discharge. Daily discharge ascertained by applying to rating, table mean 

daily gage height determined by inspecting recorder graph. Records excellent, 

except for period December to February, for which they are good. At times 

during these three months there is a possibility of slight backwater from ice.

COOPERATION. Since December 16, 1917, station has been maintained by Utah 

Power & Light Co., which made all discharge measurements during year.

COLORADO RIVER NEAR TOPOCK, ARIZ.

LOCATION. In E. ^ sec. 16, T. 7 N., R. 24 E., at head of canyon If miles below 

Atchison, Topeka & Santa Fe Railway bridge at Topock, Mohave County, and 

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

DRAINAGE AREA. 171,000 square miles (169,000 square miles at Hardyville, Ariz., 

plus about 2,000 square miles between Hardyville and gaging station).
14 SURFACE WATER SUPPLY, 1918, PART IX.

RECORDS AVAILABLE. February 1, 1917, to September 30, 1918.

GAGE. Stevens water-stage recorder on right bank just above point where river 

rapidly narrows and enters rock canyon; inspected by G. M. Bobst.

DISCHARGE MEASUREMENTS. Made from cable just below gage.

CHANNEL AND CONTROL. Above gage, channel is wide and bed, composed of loose 

sand, is constantly shifting. At low stages large sand bars form numerous islands 

between Topock and the gage. Below gage, river enters steep-walled rock canyon and channel rapidly narrows from about 800 to 400 feet. Bed in canyon 

shifts during floods. No well-defined control.

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

15.5 feet at 4 a. m. June 30 (discharge, 99,000 second-feet); minimum stage, 

1.2 feet September 12 (discharge, 4,900 second-feet).

1917-18: Maximum stage recorded, 27 feet about July 1, 1917, determined from 

flood marks on gage (discharge determined from extension of rating curve, about 

156,000 second-feet); minimum stage recorded during 1918.

DIVERSIONS. Water is diverted for irrigation and the development of power from 

main river and tributaries above the station.

ACCURACY. Stage-discharge relation not permanent. Standard rating curve fairly 

well defined below 90,000 second-feet, applicable direct February 1 to June 20; 

indirect method for shifting control used June 21 to September 30. Operation 

of water-stage recorder satisfactory. Mean daily gage height determined by inspecting recorder graph. Daily discharge ascertained by applying mean daily 

gage height to rating table except for period for which the shifting-control 

method was used. Records fair.

Sept. 30, 1918.

HORSE CREEK BASIN. 

HORSE CREEK AT DANIEL, WTO.

LOCATION. About sec. 2, T. 33 N., R. Ill W., at highway bridge three-fourths mile 

south of Daniel, Lincoln County. No tributary between station and mouth.

DRAINAGE AREA. 193 square miles (measured on map of United States Geological 

Survey; scale, 1:500,000).

RECORDS AVAILABLE. 7April 1, 1915, to November 18, 1918, when station was discontinued. State engineer maintained station at this point during 1913 and 1914.

GAGE. Vertical staff on upstream side of left abutment; read by Mrs. S. R. Hill 

and W. D. Blackman.
18 SURFACE WATER SUPPLY, 1918, PART IX.

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

CHANNEL AND CONTROL. Channel composed of gravel; control is 100 feet below

gage at small rapids; shifted slightly during 1918. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 5.7 feet at 10

a. m. June 16 (discharge, 1,530 second-feet). Minimum discharge probably

occurs during winter. 

ICE. Stage-discharge relation seriously affected by ice; observations discontinued

during winter. 

DIVERSIONS. Prior to December 31, 1916, adjudicated diversions of 161 second-feet

from Horse Creek, all above the station. 

REGULATION. None. 

ACCURACY. Stage-discharge relation slightly shifting. Rating curve used October

1 to November 19, well defined; curve used April 22 to November 18, fairly well

defined between 15 and 1,200 second-feet. Gage read to hundredths once daily.

Daily discharge ascertained by applying daily gage height to rating table.

Owing to uncertainty in gage heights, records can not be considered better

than fair.

Discharge measurements of Horse Creek at Daniel, Wyo., during the year ending Sept. 30,

1918.

COTTONWOOD CHEEK BASIN. 

COTTONWOOD CREEK NEAR BIG PINEY, WYO.

LOCATION. About sec. 21, T. 32 N., R. Ill W., at highway bridge near Hayden's^ 

ranch, 16 miles north of Big Piney, Lincoln County.

DRAINAGE AREA. 241 square miles (measured on United States Geological Survey 

map; scale, 1:500,000).

RECORDS AVAILABLE. April 25, 1916, to September 30, 1918.

GAGE. Creek flows in tw^ channels 1 mile apart; vertical staff on north channel, and 

Stevens water-stage recorder on south channel, installed May 7, 1918, at datum of 

vertical staff used previously; both gages read by Mrs. J. G. Hayden.

DISCHARGE MEASUREMENTS. Made from bridge on each channel or by wading.

CHANNEL AND CONTROL. North channel: Channel composed of coarse gravel; control 

shifted during 1918, owing to backwater from drift lodged on fence near control. 

South channel: Channel composed of sand and gravel; control shifted after high 

water of 1918.

EXTREMES OP DISCHARGE. North channel: Maximum stage recorded during year,. 

4.2 feet at 8 p. m. June 16, affected by backwater (discharge, 586 second-feet); 

minimum stage possibly occurred during winter, when |pcords were discontinued. 

South channel: Maximum stage recorded during year, 5.0 feet from 8 a. m. to 

2 p. m. June 17 (discharge, 355 second-feet); minimum stage recorded, 1.8 feet 

November 15, 1917 (discharge, practically zero).

ICE. No data.

DIVERSIONS. Prior to December 31, 1916, adjudicated diversions of 38 second-feet 

from Cottonwood Creek above station and 55 second-feet below.

REGULATION. Diversion works at head of south channel control flow through south 

channel during low stages.

ACCURACY. North channel: Stage-discharge relation fairly permanent except for 

period June 6 to 30, when drift caused backwater. Rating curve fairly well 

defined. Gage read to hundredths twice daily during high water and once daily 

during August and September. Daily discharge ascertained by applying mean 

daily gage height to rating table. Records fair.

South channel: Stage-discharge relation shifted after high water. Rating curve 

fairly well defined; applied indirectly July 1 to September 30. Gage read to hundredths once daily from October 1 to May 6. BeginningrMay 7 gage heights taken 

from water-stage recorder which operated satisfactorily. Records good.

LOCATION. About sec. 33, T. 32 N., R. 108 W., at highway bridge a quarter of a mile 

south of Ne vfork, Fremont County. No tributary between station and mouth 

.1 mile below.

DRAINAGE AREA. 348 square miles (measured on map of United States Geological 

Survey; scale, 1:500,000).

RECORDS AVAILABLE. April 1,1905, to October 31,1906; May 11, 1915, to September 

30, 1918.

GAGE. Vertical staff on downstream side of left abutment; read by Mrs. Pearl Eppelman, John Tarkelson, and Gus Eppleman. Gage a quarter of a mile upstream 

used during 1905; gage for 1906 located at bridge and referred to datum 0.27 foot 

higher than present gage.

DISCHARGE MEASUREMENTS. Made from two-span highway bridge or by wading.

CHANNEL AND CONTROL. Channel composed of sand and gravel. Control 100 feet 

downstream at gravel bar; affected by backwater from New Fork during high 

water of 1918. Banks are overflowed at stage of 6 feet.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 6.8 feet at 6 a. m. 

June 11 (discharge, 3,020 second-feet); minimum discharge probably occurs 

during winter.

ICE. Stage-discharge relation seriously affected by ice; observations discontinued.

DIVERSIONS. Prior to December 31, 1916, adjudicated diversions of 119 second-feet 

from East Fork, all above station.

REGULATION. Flow of East Fork regulated to minor extent by many small lakes at 

headwaters.

ACCURACY. Stage-discharge relation fairly permanent except when affected by backwater. Rating curve used October 1 to November 30, fairly well denned; curve 

used April 4 to September 30, well denned throughout. Gage read to hundredths 

twice daily. Daily discharge ascertained by applying mean daily gage height 

to rating table. Records excellent except for June and August, for which they 

> are fair.

ASHLEY CHEEK BASIN.

ASHLEY CREEK NEAR VERNAL, UTAH.

LOCATION. In sec. 12, T. 3 S., R. 20 E., three-quarters of a mile above heading of 

power canal of Vernal Milling & Light Co., 4 miles above mouth of Dry Fork, 

and 12 miles northwest of Vernal, Uinta County.

DRAINAGE AREA. 101 square miles (measured on topographic maps).

RECORDS AVAILABLE. June 6, 1914, to September 30, 1918. From October 8, 1911, 

to June 5, 1914, fragmentary records were obtained at 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.
ASHLEY CREEK BASIN. 39

<G MM. Gurley water-stage recorder on left bank three-quarters of a mile above heading of power canal, installed November 14, 1917; inspected by William Mort. 

Staff gage on right bank 850 yards above heading of power canal, July 12 to November 13, 1917. Lietz water-stage recorder on right bank about 400 yards above 

heading of power canal, April 15, 1915, to June 17, 1917, at same location as 

vertical staff gage from which fragmentary records had been obtained since June 

6, 1914. Description of gages used previous to that date published in WaterSupply Paper 459.

DISCHARGE MEASUREMENTS. Prior to June 17, 1917, made from cable about 75 feet 

above gage or by wading; after that date, by wading.

OHANNEL AND CONTROL. Bed steep and rough; subject to change during high water. 

No well-defined control.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 4.50 feet at 12.30 

p. m. May 25 (discharge, 324 second-feet); minimum discharge, 35 second-feet 

at 3 p. m. February 15. As gage was read once each week, it is probable that the 

preceding determinations do not represent the extreme stages reached.

1911-1918: Maximum discharge recorded, 1,350 second-feet, May 23, 1914 

(probably exceeded by high water in June, 1917); minimum stage recorded, 1.34 

feet April 8, 1917 (discharge. 28 second-feet).

ICE. Stage-discharge relation apparently not affected by ice.

DIVERSIONS. Above all diversions.

REGULATION. None.

ACCURACY. Stage-discharge relation changed when gage was moved November 14, 

1917; not affected by ice. Rating curve used October 1 to November 13, fairly 

well defined; curve used November 14 to September 30, fairly well defined between 

30 and 250 second-feet. Operation of water-stage recorder not satisfactory. 

Weekly readings by observer used except November 17-30 and February 2-7. 

Daily discharge ascertained by applying to rating table mean daily gage height 

determined by inspecting recorder graph or by applying weekly gage height to 

rating table. Monthly discharge not comouted. Records fair.

DTJCHESNE RIVER AT MYTON, UTAH.

LOCATION. In NW. J sec. 25, T. 3 S., R. 2 W., at highway bridge at Myton, Duchesne 

County, 3 miles below mouth of Lake Fork and 15 miles above mouth of Uinta 

River.

DRAINAGE AEEA. 2,750 square miles (measured on topographic maps).

RECORDS AVAILABLE. October 26, 1899, to November 30, 1910; July 26, 1911, to 

September 30, 1918.

GAGE. Chain gage near left end of bridge, installed August 6, 1910; readings about 

2.7 feet lower than those on previous gage; read by Abe Smith. . From October 

26,1899, to June 6,1909, chain gage at old wooden bridge half a mile below present 

site. June 6, 1909, river cut new channel and chain gage was installed July 9, 

1909, about a quarter of a mile upstream and at different datum; moved 100 feet 

downstream 1 month later; datum unchanged.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading 100 feet 

below.

CHANNEL AND CONTROL. Bed composed of coarse gravel. Principal control probably 

a gravel bar at the ford 100 or 200 feet below the gage; shifting at long intervals. 

Banks comparatively low, but not subject to overflow, although subject to erosion 

during high water.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 5.7 feet at 5.35 

p. m. June 10 (discharge, 4,790 second-feet); minimum stage recorded, 1.0 foot 

September 1 and 2 (discharge, 56 second-feet).

1899-1918: Maximum stage recorded, 7.4 feet June 20, 22, and 23, 1917 (discharge, 9,690 second-feet); minimum stage recorded in 1918.

ICE. Stage-discharge relation seriously affected by ice.

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

irrigation above station.

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

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

ACCURACY. Stage-discharge relation changed during winter; affected by ice December 18 to February 28. Rating curve used October 1 to December 17, well 

defined; curve used March 1 to September 30, well denned. Gage read to halftenths twice daily. Daily discharge ascertained by applying mean daily gage 

height to rating table except for period of ice effect. Records good.

DTTCHESNE RTVER, BASIN. 49

LAKE FORK NEAR ALTONAH, UTAH.

LOCATION. In S. J sec. 32, T. 1 N., R. 4 W., a quarter of a mile below heading of 

United States Lake Fork canal and 4J miles northwest of Altonah, Duchesne 

County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. October 15,1917, to September 30,1918. June 4 to September 

18, 1917, station maintained three-eighths mile upstream; records not directly 

comparable, as United States Lake Fork canal diverts water between stations.

GAGE. Stevens continuous water-stage recorder on right bank; installed October 15, 

1917; inspected by Warren Foote and W. R. Preece.

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

CHANNEL AND CONTROL. Bed composed of boulders and gravel; somewhat shifting. 

No well-defined control.

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

4.24 feet at 4.30 a. m. June 11 (discharge, 2,000 second-feet); minimum discharge 

not determined.

ICE. Stage-discharge relation affected by ice.

DIVERSIONS. Above all diversions except Farnsworth canal, Payne canal, and 

United States Lake Fork canal. Records of these canals for the irrigation season 

accompany records for this station.

REGULATION. A number of small lakes on the headwaters have been developed to 

store about 5,000 acre-feet.

ACCURACY. Stage-discharge relation not permanent; shifted October 15 to December 

4, and June 2. Rating curves poorly defined. Operation of water-stage recorder 

unsatisfactory as indicated in footnote to table of daily discharge. Daily discharge ascertained by applying to rating table mean daily gage height determined 

from inspection of recorder graph; shifting-control method used October 15 to 

December 4. R?c:>rds fair. 

Records of discharge of Farnsworth, Payne, and United States Lake Fork canals

for the irrigation season are published herewith to supplement the records of flow

at this station, as these are the only diversions in the Lake Fork basin above this

station. The records of daily discharge of these canals were furnished by C. C. Jacob,

Federal court water commissioner. Following these records is a table of combined

flow showing total run-off of Lake Fork including diversions.

irrigation season accompany records for this station.

REGULATION. None.

ACCURACY. Stage-discharge relation changed during winter; affected by ice December 21 to March 6. Rating curves fairly well defined between 60 and 600 secondfeet. Operation of water-stage recorder satisfactory except December 21 to April 

24, during which period weekly staff gage readings were obtained. Daily discharge ascertained by applying to rating table mean daily gage height determined 

by inspecting recorder graph. Records fair.

Records of discharge of Cedar View canal for the irrigation season are published with 

this station to supplement the records of flow at the station, as this is the only diversion 

in the Uinta River basin above this station. The records of daily discharge of this 

canal were furnished by C. C. Jacob, Federal court water commissioner. Following 

these records is a monthly table giving combined flow of Uinta River and canal, which 

is total flow of river.

RECORDS AVAILABLE. May 3, 1909, to September 30, 1918.

GAGE. Stevens continuous water-stage recorder on right bank, installed September 

11, 1917; inspected by J. P. Brockbank. Original gage, vertical staff on right 

bank at same site as present gage but at independent datiun, used May 3, 1909, 

to October 6, 1912. Inclined staff gage at same site and datum, October 7, 

1912, to April 29, 1913. Stevens continuous water-stage recorder on left bank, 

100 feet upstream, used April 30, 1913, to September 9, 1917.

DISCHARGE MEASUREMENTS. Made by wading or from cable.

CHANNEL AND CONTROL. Bed composed of coarse gravel; shifts occasionally during 

high stages. No well-defined control.

EXTREMES or DISCHARGE. Extremes for year ending September 30, 1918, uncertain. See Accuracy.

1909-1918: Maximum stage from water-stage recorder, 6.1 feet from 8 to 10 

p. m. May 23,1914 (discharge, 1,200 second-feet); minimum discharge, 12 secondfeet, March 20-23, 1912.

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. Several small ditches divert from tributaries above station.

REGULATION. A small storage reservoir on Huntington Creek above the station 

controls flow to slight extent.

ACCURACY. Operation of water-stage recorder not satisfactory owing to excessive 

clogging of inlet pipe and filling of stilling well with mud. Discharge not ascertained, as gage-height record is not an index of discharge.

into headwaters of Cache la Poudre River. Under this decree 14,371 acre-feet

was diverted in 1918 between May 19 and August 19. 

REGULATION. Diurnal fluctuation in spring from alternate melting and free/ing of

mountain snow. No artificial regulation. 

ACCURACY. Stage-discharge relation considered permanent, except during winter

when affected by ice. Rating curve well defined. Gage read to hundredths

once daily except December 1 to March 31, when it was read every other day.

Daily discharge ascertained by applying daily gage height to rating table and

interpolating for days of missing gage heights except for puriods of ice effect.

Records good at ordinary stages, but fair during high water and winter period.

76 SURFACE WATER SUPPLY, 1918, PART IX.

DRAINAGE AREA. 2,380 square miles.

EECORDS AVAILABLE. July 24, 1904, to September 30,1918, when station was discontinued.

GAGE. Friez water-stage recorder on right bank 200 feet above wagon bridge, used 

since October 15, 1915; inspected by C. H. Yust. Original gage, a chain on left 

bank, 100 feet above present location, installed July 24, 1904, and used until 

October 17, 1906; datum 0.80 foot lower than present. Inclined staff directly 

opposite chain gage, at present gage datum, used October 18, 1906, to July 27, 

1910. Friez water-stage recorder installed near staff gage and at same datum used 

July 28, 1910, to October 14, 1915, except during winter when staff gage was used.

DISCHARGE MEASUREMENTS. Made from cable just above gage. Winter measurements made from bridge at head of rapids.

CHANNEL AND CONTROL. Bed composed of sand, silt, and scattered boulders. Control is head of rapids 250 feet downstream; slightly shifting, as silt is deposited 

and later scoured out by high water. Banks high and are not overflowed.

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

19.0 feet at noon June 15 (discharge, 16,800 second-feet); minimum discharge 

occurred during winter when stage-discharge relation was affected by ice.

ICE. Stage-discharge relation affected by ice during most of winter.

DIVERSIONS. Court decrees for diversion of 35 second-feet from Grand River between 

this station and Hot Sulphur Springs.

STORAGE. Station is located at proposed Kremmling reservoir site. A dam built 230 

feet above the river bed at the mouth of Gore Canyon will impound nearly 

2,200,000 acre-feet.

REGULATION. Diurnal fluctuation during spring, caused by alternate melting and 

freezing of mountain snow.

ACCURACY. Stage-discharge relation slightly shifting. Standard rating curve well 

denned. Operation of water-stage recorder satisfactory except for brief periods 

given in footnote to table of daily discharge. Mean daily gage height obtained 

by inspection of recorder graph. Daily discharge ascertained by indirect 

method for shifting control. Records good except during winter, when they 

are fair.

78 SURFACE WATER SUPPLY, 1918, PART IX. 

GRAND RIVER AT GLENWOOD SPRINGS COLO.

LOCATION. Ifi sec. 9, T. 6 S., R. 89 W., at Glenwood Springs, Garfield County. No 

Name Creek enters Grand River 2 miles above station and Roaring Fork half a 

mile below.

DRAINAGE AREA. 4,520 square miles (measured on Nell's map of Colorado).

RECORDS AVAILABLE. January 1, 1900, to September 30, 1918; 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. See Water-Supply Paper 175 for history of early gages and gage 

used in 1905 which was also used until May 17, 1910.

DISCHARGE MEASUREMENTS. Made from cable beneath State Street bridge, one-third 

mile below gage.

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

is deposited. Control is riffle 300 feet downstream; slightly shifting. Banks are 

not overflowed except at extremely high water.

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

12.55 feet at noon June 14 and 15 (discharge, 30,100 second-feet); minimum 

stage, 1.9 feet at 3 p. m. March 17 (discharge, 155 second-feet).

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

river open.

DIVERSIONS. Court decrees for diversion of 13 second-feet from Grand River between 

this station and the one near Kremmling for irrigation, 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 the day at low water, but has insufficient pondage to control it 

. for more than a few hours.

ACCURACY. Stage-discharge relation changed gradually during October, November, 

and December. Standard rating curve used October 1 to December 31, well 

defined; curve used January 1 to September 30. well defined. Operation of 

water-stage recorder satisfactory except for short periods as indicated in footnote 

to daily-discharge table. Daily discharge ascertained by applying to rating table 

mean daily gage height obtained by inspecting recorder graph, except for period 

October 1 to December 31 for which the shifting-control method was used and 

except as indicated in footnote to daily-discharge table. Records excellent.

COOPERATION. Gage heights furnished by United States Forest Service.

GRAND RIVER NEAR FRUITA, COLO.

LOCATION. In sec. 20, T. 1 N., R. 2 W. New Mexico principal meridian, at highway 

bridge 1$ miles south of Pruita, Mesa County. Nearest important tributary, 

Little Salt Wash, enters 1 mile below station; Gunnison River enters at Grand 

Junction, 12 miles above.

DRAINAGE AREA. 16,800 square miles (measured on Hayden's atlas).

RECORDS AVAILABLE. Flood records during 1908, 1909, and 1910; continuous records 

April 1, 1911, to September 30, 1918.

GAGE. Chain on downstream side of left span; read by L. C. Jones. Prior to May 3, 

1911, gage was vertical staff attached to center pier; datum 0.05 foot lower.

DISCHARGE MEASUREMENTS. Made from three-span highway bridge.

CHANNEL AND CONTROL. Bed composed of silt and gravel which will shift during 

high water, scouring out at high stages and filling in afterwards. Control is 

riffle 600 feet downstream; somewhat shifting. Banks are high and are not overflowed, except at stages above 14 feet.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 13.9 feet at 5 p. m. 

June 14, and 8 a. m. June 15 (discharge, 57,000 second-feet); minimum stage 

occurs during winter.

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. Court decrees for diversion of 788 second-feet from Grand River between 

Palisade station and Fruita.

REGULATION. None.

ACCURACY. Stage-discharge relation practically permanent except during high 

water when channel and control scour and fill. Rating curve well defined below 

20,000 second-feet, but uncertain above, owing to the scour and fill. Gage read 

to tenths twice daily. Daily discharge ascertained by applying mean daily 

gage height to rating table. Records good except during high water when they 

may be 10 to 15 per cent too small, as indicated by comparison with flow of Grand 

River near Palisade and Gunnison River near Grand Junction.

COOPERATION. Gage heights furnished by Weather Bureau.

BLUE RIVER AT DILLON, COLO.

LOCATION. In sec. 18, T. 5 S., R. 77 W., at highway bridge on edge of Dillon, Summit 

County. Nearest tributaries, Snake River and Tenmile Creek, enter a short distance below.

DRAINAGE AREA. 110 square miles (measured on Forest atlas).

RECORDS AVAILABLE. October 15, 1910, to September 30, 1918.

GAGE. Vertical staff on right abutment of bridge facing channel; read by E. Cooke, 

M. D. Pierce, and Frank Sopir.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Bed composed of compact gravel upon which lodges 

detritus from hydraulic dredges, near Breckenridge. Control is riffle 50 feet downstream, which shifted during high water of 1918. Banks high and not overflowed. Point of zero flow, 0.4 foot (± .1).

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 3.7 feet at 7 p. m. 

June 16 (discharge, 900 second-feet); minimum discharge of 20 second-feet occurred February 28 and March 1.

ICE. Stage-discharge relation affected by ice.

DIVERSIONS. Court decrees for diversion of 2.3 second-feet for irrigation from Blue 

River above station and 63 second-feet below; also placer decrees for diversion of 

118 second-feet near Breckenridge. Unadjudicated diversion from the headwaters of Blue River across Boreas Pass to Tarryall Creek.

REGULATION. Diurnal fluctuation during spring, caused by alternate melting and 

freezing of mountain snow.

ACCURACY. Stage-discharge relation not permanent, but shifted slightly after high 

water; affected by ice. Standard rating curve well denned below 700 secondfeet. Gage read to half-tenths twice daily. Daily discharge ascertained by 

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

Indirect method for shifting control June 1 to August 31. Records good except 

during winter, for which they are fair.

SNAKE RIVER AT DILLON, COLO;

LOCATION. In. sec. 18, T. 5 S., R. 77 W., at highway bridge 100 yards above mouth 

of river, at Dillon, Summit County. Nearest tributary, a small stream, enters 

from north 1 mile above station.

DRAINAGE AREA. 92 square miles (measured on Forest atlas).

RECORDS AVAILABLE. October 15, 1910, to September 30, 1918.

GAGE. Vertical staff on downstream side of right bridge abutment; read by Frank 

Sopir. Prior to April 26, 1913, gage was 2 feet farther upstream, and although referred to same datum, water piled up on gage during high water, giving a higher 

reading for same discharge.

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

CHANNEL AND CONTROL. Bed composed of small boulders, rough, but permanent. 

Control 50 feet downstream; shifted during 1918. Banks are not overflowed.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 3.1 feet at 7 a. m. 

and 7,p. m. June 15 (discharge, 1,170 second-feet); minimum discharge 8 secondfeet for several days during winter.

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. Snake River ditch of Summit County Power Co. diverts about 30 

second-feet from Snake River above Dillon. Irrigation decree for 4.5 second-feet 

above Dillon.

REGULATION. Operation of power canal affects low-water flow.

ACCURACY. Stage-discharge relation not permanent; affected by ice. Rating curve 

used from October 1 to May 31, well defined below 600 second-feet. Curve used 

from June 15 to September 30, fairly well defined. Shifting-control method used 

June 1-14. Gage read to hundredths twice daily. Daily discharge ascertained 

by applying mean daily gage height to rating table except for period for which 

shifting-control method was used and except as indicated in footnote to dailydischarge table. Records good except for winter, for which they are fair.

TENMILE CREEK AT DILLON, COLO. ,

LOCATION. In sec. 18, T. 5 S., R. 77 W., at highway bridge 300 yards above mouth 

of creek, in Dillon, Summit County. Nearest tributary, Canon Creek, enters 

from west 4 miles above.

DRAINAGE AREA. 113 square miles (measured on Forest atlas).

RECORDS AVAILABLE. October 15, 1910, to September 30, 1918.

 GAGE. Vertical staff on downstream side of center pier; read by Frank Sopir and E. 

Cooke. Prior to June 10, 1914, gage was at side of pier where during high stages 

the water piled up on the gage, giving a higher reading for the same discharge, 

although referred to the same datum.

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

CHANNEL AND CONTROL. Bed composed of small boulders; rough but permanent. 

Control 30 feet downstream; shifted during 1918. Banks high and are not overflowed.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 4.25 feet at 8 a. m. 

June 11 (discharge, 1,600 second-feet); minimum discharge of 2 second-feet 

occurred February 15, 16, 17, and 20.

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. Court decrees for diversion of 11 second-feet from Tenmile Creek above 

station.

REGULATION. Diurnal fluctuation during spring, caused by alternate melting and 

freezing of mountain snow.

ACCURACY. Stage-discharge relation not permanent, but shifted during high water; 

affected by ice. Standard rating curve well defined below 1,000 second-feet. 

Shifting-control method used June 9 to September 30. Gage read to hundredths 

twice daily. Daily discharge ascertained by applying mean daily gage height 

to rating table except for period for which shifting-control method was used 

and except for period of ice effect. Records good except for winter, for which 

they are fair.

92 SURFACE WATfeR SUPPLY, 1918, PART IX.

EAGLE RIVER AT REDCLIFF, COLO.

LOCATION. In sec. 29, T. 6 S., R. 80 W., at footbridge in Redcliff, Eagle County. 

Nearest tributary, Turkey Creek, enters 100 yards below station; HomestakeCreek enters 1 mile below.

DRAINAGE AREA. 74 square miles (measured on topographic map).

RECORDS AVAILABLE. January 8, 1911, to September 30, 1918.

GAGE. Chain on downstream side of footbridge; read by forest ranger. Staff gage 

in same section and referred to same datum, read during high water.

DISCHARGE MEASUREMENTS. Made from highway bridge 800 feet above station or by 

wading.

CHANNEL AND CONTROL. Bed composed of boulders and is very rough. Control 

short distance below gage; shifts between narrow limits. Banks are high and 

are not overflowed.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 3.5 feet at 7.30 a. m.. 

June 10,11, and 12 (discharge, 685 second-feet); minimum stage, 0.01 foot at 7 a. m. 

October 15 (discharge, 1 second-foot).

ICE. Stage-discharge relation not affected by ice during year.

DIVERSIONS. Court decrees for diversion 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 1918, 2,210 acre-feet diverted under this 

decree.

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 not permanent but shifted slightly; unaffected 

by ice. Rating curve used from October 1 to May 22 well defined below 500 

second-feet; curve used May 27 to September 30 well defined below 700 secondfeet. Indirect method for shifting control used January 3 to March 5, and May 

23-25. Gage read to hundredths usually twice daily. Daily discharge ascertained 

by applying mean daily gage height to rating table except for periods for which 

the shifting-control method was used. Records good.

COOPERATION. Gage heights furnished by United States Forest Service.

HOMESTAKE CREEK NEAR RED CLIFF, COLO.

LOCATION. In sec. 30, T. 6 S., R. 80 W., a quarter of a mile above mouth of creek, at 

first Forest Service bridge, 1 mile from Redcliff, Eagle County; below all tributaries.

DRAINAGE AREA. 64 square miles (measured on topographic map).

RECORDS AVAILABLE. January 8, 1911, to September 30, 1918.

GAGE. Vertical staff attached to center pier of bridge used since October 18, 1917; 

at practically same location as gage used January 8, 1911, to August 16, 1914. 

August 17, 1914, to October 17, 1917, gage was a quarter of a mile upstream. 

Read by forest ranger.

DISCHARGE MEASUREMENTS. Made from bridge or by wading near by.

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

50 feet downstream at small rapids; apparently permanent.

EXTREMES or1 DISCHARGE. Maximum stage recorded during year, 6.2 feet at 9 a. m. 

June 24 (discharge, 1,300 second-feet); minimum discharge probably occurred 

during winter when stage-discharge relation was affected by ice.

ICE. Stage-discharge relation seripusly affected by ice; observations discontinued.

DIVERSIONS. Court decrees for diversion of 1.2 second-feet from tributary of Homestake Creek.

REGULATION. Diurnal fluctuation during spring from alternate melting and freezing 

of mountain snow.

ACCURACY. Stage-discharge relation apparently permanent. Rating curve used 

prior to October 18, when gage location was changed, well defined below 650 

second-feet; curve used after that date not well defined. Gage read at irregular 

intervals. Daily discharge ascertained by applying daily gage height to rating 

table and estimating for days of no gage height. One reading does not represent 

mean daily gage height during spring. Records poor during high water and fair 

for remainder of year.

COOPERATION. Gage heights furnished by United States Forest service.

ROARING FORE AT ASPEN, COLO.

LOCATION. In sec. 7, T. 10 S., R. 84 W., at bridge near old power plant at Aspen, 

Pitkin County. Castle, Maroon, and Hunter creeks all enter below.

DRAINAGE AREA. 109 square miles (measured on topographic map).

RECORDS AVAILABLE. February 25, 1915, to September 30, 1918. From January 1, 

1911, to February 24, 1915, station was maintained just below Cooper Avenue 

bridge, three-quarters of a mile upstream.

GAGE. Vertical staff at downstream end of right bridge abutment; read by H. W. 

Wood and Francis McDonnell. Gage used at original section was a vertical staff 

fastened to old crib abutment on right bank, 25 feet below Cooper Avenue bridge; 

no determined relation between two gages.

DISCHARGE MEASUREMENTS. Made from single-span bridge or by wading near by.
GKAND EIVEE BASIN. 99>

CHANNEL AND CONTROL. Bed composed of small boulders and is fairly smooth. 

Control not well defined; shifts occasionally. Banks high and not subject to 

overflow.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 5.8 feet at 8 a. m. 

June 13 (discharge, 2,380 second-feet); minimum stage, 1.06 feet at 9 a. m. November 28 (discharge, 28 second-feet).

ICE. Stage-discharge relation practically unaffected by ice during winter.

DIVERSIONS. Salvation ditch, which has a decree for 58 second-feet, diverts water 

above station from middle of May to middle of September. It was not used 

during 1918. The mines at Aspen pump into the river about 6 second-feet, 

which enters above the station.

REGULATION. Diurnal fluctuation during spring caused by alternate melting and 

freezing of mountain snow.

ACCURACY. Stage-discharge relation not permanent, but shifted during high water.. 

Rating curve used from October 1 to May 23 well defined below 2,000 second-feet; 

curve used June 5 to September 30 well defined; shifting-control method used 

May 24 to June 5. Gage read to hundredths twice daily. Daily discharge ascertained by applying mean daily gage height to rating table except for period for 

which shifting-control method was used. Records good.

ROARING FORK BELOW ASPEN, COLO.

LOCATION. In sec. 1, T. 10 S., R. 85 W., at first highway bridge 2 miles below Aspen, 

Pitkin County. Nearest tributary above is Castle Creek; nearest below, Maroon 

Creek.

DRAINAGE AREA. 223 square miles (measured on topographic map).

HECORDS AVAILABLE. October 18, 1913, to June 30, 1918, when station was discontinued.

GAGE. Vertical staff on left abutment of bridge, facing channel; read at irregular 

intervals by forest ranger.

DISCHARGE MEASUREMENTS. Made from two-span bridge.

CHANNEL AND CONTROL. Bed composed of gravel and small boulders; slightly 

shifting. No well-defined control. Banks are high and not subject to overflow.

EXTREMES OF DISCHARGE. Data too few.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. Between this station and the one at Aspen there are a number of small 

diversions, some of which, return the water to the river above the station. Roaring 

Fork Light & Power Co. diverts water from Maroon Creek into Castle Creek and 

thence into Roaring Fork above station.

KEGULATION. Diurnal fluctuation during spring from alternate melting and freezing 

of mountain snow.

ACCURACY. Stage-discharge relation shifted between narrow limits. Standard rating 

curve well defined below3,000second-feet. Gageread tohundredthssemiweekly. 

Daily discharge ascertained by applying daily gage height to rating table and 

estimating for days when gage was not read. During spring, one reading does 

not represent mean for day. Records poor.

COOPERATION. Gage heights furnished by United States Forest Service.

The following discharge measurement was made by T. J. Watkins: 

January 24, 1918: Gage height, 0.15 foot; discharge, 125 second-feet.

ROARING FORK AT GLENWOOD SPRINGS, COLO.

LOCATION. In sec. 9, T. 6. S., R. 89 W., 1,500 feet above month of river, at Glenwood 

Springs, Garfield County.

DRAINAGE AREA. 1,450 square miles (measured on Nell's map of Colorado).

RECORDS AVAILABLE. April 6, 1906, to September 30, 1909; September 21, 1910, to 

September 30, 1918.

GAGE. Gurley water-stage recorder installed October 27, 1917, and referred to inclined staff on left bank 800 feet above highway bridge, used since November 20, 

1915; inspected by United States Forest Service. Chain gage on downstream side 

of highway bridge previously used; relation between gages not determined.
102 SURFACE WATER SUPPLY, 1918, PART IX.

DISCHARGE MEASUREMENTS. Made from single-span highway bridge.

CHANNEL AND CONTROL. Bed composed of boulders and coarse gravel, practically

permanent during 1918. No well-defined control. Banks high and not subject

to overflow. 

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

8.45 feet at 8 a. m. June 14 (discharge, 17,600 second-feet); minimum stage, 0.64

foot at 4 p. m. February 16 (discharge, 340 second-feet). 

ICE. Stage-discharge relation not seriously affected by ice, as river seldom freezes

over, and only occasionally does slush or anchor ice form. 

DIVERSIONS. There are court decrees for diversions of 164 second-feet from Roaring

Fork between Glenwood Springs and station below Aspen. 

REGULATION. Diurnal fluctuation during spring, caused by alternate melting and

freezing of mountain snow. 

ACCURACY. Stage-discharge relation permanent; not affected by ice. Rating curve

well defined. Operation of water-stage recorder satisfactory. Daily discharge

ascertained by applying to rating table mean, gage height obtained by inspecting

gage-height graph. Records excellent except during winter, when possibility of

slight ice effect makes them good. 

COOPERATION. Gage heights furnished by United States Forest Service.

CASTLE CREEK NEAR ASPEN, COLO.

LOCATION. In sec. 35, T. 10 S., R. 85 W., 75 feet below highway bridge, 4| miles 

above Aspen, Pitkin County. No inflow below, except spring run-off from small 

gulches; nearest tributary above, Conundrum Creek, enters 1 mile upstream.

DRAINAGE AREA. 62 l square miles (measured on topographic map).

RECORDS AVAILABLE. February 16, 1911, to September 30, 1918.

GAGE. Gurley water-stage recorder on left bank, 75 feet below bridge; inspected by 

forest ranger. Staff on opposite bank at datum 1.0 foot higher than present gage, 

used February 16, 1911, to February 28, 1912. Vertical staff on right abutment of 

bridge at present datum used February 29, 1912, to April 11, 1915, but owing to 

slope of stream, gage readings were somewhat higher.

DISCHARGE MEASUREMENTS. Made from two-span bridge or by wading near by.

CHANNEL AND CONTROL. Bed composed of coarse gravel; shifts during high water. 

Control is small rapids just below cable; shifting at intervals. Left bank is high 

and not subject to overflow; right bank subject to overflow a distance of 75 feet at 

gage height 4.3 feet.

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

3.9 feet at 7 p. m. June 15 (discharge, 1,090 second-feet): minimum stage, 0.68 

foot at 5 a. m. February 26 (discharge, 24 second-feet).

ICE. Stage-discharge relation affected by ice.

DIVERSIONS. No water diverted aboye station except possibly for a small amount of 

meadow irrigation. Court decrees for diversion of 160 second-feet below station.

REGULATION. Diurnal fluctuation during spring caused by alternate melting and 

freezing of mountain snow.

ACCURACY. Stage-discharge relation not permanent; shifted at beginning of high 

water. Rating curve used October 1 to June 3 fairly well defined; curve used 

June 8 to September 30 well denned. Operation of water-stage recorder satisfactory except for periods indicated in footnote to daily-discharge table. Daily 

discharge ascertained by applying to rating table mean daily gage height determined by inspection of gage-height graph, except for period of ice effect; shifting-control method used April 1 to June 3. Records excellent except for period 

January 1 to June 8, for which they are fair.

COOPERATION. Gage heights furnished by United States Forest Service.

GUNNISON RIVER NEAR GTTNNISON, COLO.

LOCATION. In sec. 3, T. 49 N., R. 1 W. New Mexico principal meridian, at highway 

bridge 2 miles west of Gunnison, Gunnison County. Nearest tributary, Tomichi 

Creek, enters 1 mile below.

DRAINAGE AREA. 1,010 square miles (measured on Hayden's atlas).

RECORDS AVAILABLE. November 27, 1910, to November 30, 1914; April 27, 1916, to 

September 30, 1918.

GAGE. Bristol water-stage recorder on downstream side of right abutment, referred 

to chain gage in center of bridge. Chain gage used subsequent to June 19, 1918; 

read by C. W. Chinery. April 27 to September 30, 1916, gage referred to vertical 

staff at right abutment having datum 0.15 foot higher.

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

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

during high water. Control at well-defined rapids below bridge; shifted during 

high water of 1918. Banks not subject to overflow except during extremely 

high water.

EXTREMES OF DISCHARGE. Maximum stage from water-stage recorder, 4.05 feet at 

8 a. m. June 13 (discharge estimated at 11,400 second-feet); minimum discharge 

of 180 second-feet occurred on several days during December and January.

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. Court decrees for diversion of 276 second-feet from Gunnison River 

between this station and the forks at Almont.

REGULATION. None.

ACCURACY. Stage-discharge relation shifted during and subsequent to the high 

water of June; affected by ice. Standard rating curve well defined below 6,000 

second-feet; was used direct prior to June 2. During the period June 2-21 

there was considerable overflow and two overflow curves were used based upon 

available information and a comparison with flow at Almont. From June 22, 

when overflow was practically stopped by filling in with broken rock, to September 30, the shifting-control method was used based upon a discharge measurement made in October, 1918, and upon comparison with flow at Almont. 

Operation of water-stage recorder satisfactory prior to June 18; thereafter chain 

gage was read to half-tenths twice daily. Daily discharge ascertained by applying mean daily gage height to rating table except for periods of ice effect and 

periods for which the shifting-control method was used. Records fair.

GTTNNISON RIVER NEAR GRAND JUNCTION, COLO.

LOCATION. In NW. i sec. 35, T. 1 S., R. 1 W., a quarter of a mile below Redlands 

Irrigation & Power Co.'s canal and 1£ miles above mouth of Gunnison River in 

Grand Junction, Mesa County, below all tributaries.

DRAINAGE AREA. 7,920 square miles (measured on map of Colorado Geological Survey; scale, 1 : 500,000).

RECORDS AVAILABLE. April 1, 1917, to September 30,1918. From October 19,1894, 

to December 21,1895, and May 2,1897, to September 30,1899, station maintained 

nearer mouth.

GAGE. Vertical staff at left bank a quarter of a mile below canal intake; read by 

employee of Redlands Irrigation & Power Co. Original gage vertical staff attached to wall of Denver & Rio Grande Railroad Co.'s pump house some distance 

below present site. Moved July 5, 1895, to highway bridge 1 mile below present gage. Relation between different gages not determined.

DISCHARGE MEASUREMENTS. Made from car and cable at gage section.

CHANNEL AND CONTROL. Bed composed of well-compacted gravel; permanent. Control at rapids 500 feet downstream; practically permanent. Banks high and not 

subject to overflow.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 10.1 feet at 6.4& 

p. m. June 14 (discharge, 17,600 second-feet); minimum stage, 1.35 feet at 8 

a. m. August 5 (discharge, 190 second-feet).

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

DIVERSIONS. Below all diversions from Gunnison River. Most of water diverted 

through Redlands canal is used for pumping and is returned to Grand River 

below the Gunnison.

COMBINED FLOW. Combined flow <of Gunnison River and Redlands power canal 

represents flow of Gunnison River which enters Grand River less about 25 secondfeet which is used during irrigation season.

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

defined. Gage read to half-tenths twice daily. Daily discharge ascertained by 

applying mean daily gage height to rating table. Records excellent except for 

winter period, for which they are good.

COOPERATION. Daily gage heights furnished by Redlands Irrigation & Power Co.

114 SURFACE WATER SUPPLY, 1918, PART IX.

TOMICHI CREEK AT SARGENTS, COLO.

LOCATION. In NW. \ sec. 28, T. 48 N., R. 5 E., at railroad bridge three-quarters of a 

mile west of Sargents, Saguache County. Nearest tributary, Marshall' Creek, 

enters a quarter of a mile above.

DRAINAGE AREA. 165 square miles (revised) (measured on Hayden's atlas).

RECORDS AVAILABLE. May 12,1917, to September 30,1918.

GAGE. Lallie water-stage recorder installed October 5, 1917, and referred to former 

vertical staff attached to downstream piling of railroad bridge; read by W. S. Cole.

DISCHARGE MEASUREMENTS. Made by wading or from pile bent bridge.

CHANNEL AND CONTROL. Bed composed of gravel; shifting. Control 30 feet down 

stream a^small rapids of compact gravel; practically permanent.

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

3.4 feet during forenoon of May 29 (discharge, 410 second-feet); minimum discharge 

probably occurs during winter.

ICE. Stage-discharge relation seriously affected by ice; observations discontinued.

DIVERSIONS. A few small ditches divert water for irrigation above Sargents.

REGULATION. Diurnal fluctuation during spring, caused by alternate melting and 

freezing of mountain snow.

ACCURACY. -/Stage-discharge relation permanent. Rating curve well defined. 

Operation of water-stage recorder satisfactory. Daily discharge ascertained by 

applying to rating table mean daily gage height determined by inspecting gageheight graph. Wide control at high water makes station nonsensitive, and for 

that reason records for high water are good and for other stages excellent.

Discharge measurements of Tomichi Creek at Sargents, Colo., during the year ending

Sept. 30, 1918.

LAKE FORK AT LAKE CITY, COLO.

LOCATION. In sec. 34, T. 44 N., R. 4 W., at private bridge one-third mile above 

Henson Creek, in Lake City, Hinsdale County.

DRAINAGE AREA. 126 square miles (measured on topographic map).

RECORDS AVAILABLE. April 21 to September 30,1918.

OAGE. Vertical staff fastened to downstream side of right bridge abutment; read by 

Eugene Otis.

DISCHARGE MEASUREMENTS. Made by wading or from bridge.

 CHANNEL AND CONTROL. Bed composed of coarse gravel well compacted; permanent. Control at small rapids 250 feet downstream; apparently permanent. 

Banks not subject to overflow except during extremely high stages.

EXTREMES OF DISCHARGE. Maximum stage recorded, 2.57 feet at 8 a. m. June 14 

(discharge, 980 second-feet); minimum discharge occurs during winter.

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. Practically none which do not return to stream above station. Court 

decrees for diversions of 22 second-feet from Lake Fork below station.

REGULATION. Flow naturally regulated by Lake San Cristobal, 4 miles upstream; 

area 1 square mile. During low water operation of power plant, 1 mile upstream, 

may influence discharge slightly.

ACCURACY. Stage-discharge relation permanent. Rating curve well defined. Gage 

read to hundredths twice daily. Daily discharge ascertained by applying mean 

daily gage height to rating table. Width of control at high water makes station 

nonsensitive, and for that reason records for that period are good, and for other 

periods, excellent.

GRAND BIVEB BASIN.

SURFACE CREEK AT CEDAREDGE, COLO.

121

LOCATION. About sec. 29, T. 13 S., B. 94 W., at Cedaredge, Delta County. Nearest 

tributary, Mill Creek, enters 4 miles above.

DRAINAGE AREA. 43 square miles (measured on Forest atlas).

RECORDS AVAILABLE. May 16, 1917, to September 2, 1918.

GAGE. Lallie water-stage recorder referred to vertical staff fastened to right concrete 

abutment of footbridge, 400 feet upstream from highway bridge in Cedaredge.

DISCHARGE MEASUREMENTS. Made from footbridge at gage section.

CHANNEL AND CONTROL. Bed composed of small boulders filled in behind control 

which is old concrete weir filled up flush with boulders and gravel, located 12 feet 

downstream. Control permanent. Above stage 0.7 foot water flows through an 

overflow channel which may shift somewhat.

EXTREMES OF DISCHARGE. Maximum stage during year, 1.5 feet at 10 p. m. May 

14 (discharge, 330 second-feet); minimum discharge occurs during winter.

ICE. No data. Flow very small as most of it is stored during winter.

DIVERSIONS. Court decrees for diversion of 142 second-feet from Surface Creek above 

station, of which 67 second-feet is for diversion out of drainage basin. Below, 

court decrees for 272 second-feet.

REGULATION. Alternate melting and freezing of snow in mountains caused diurnal 

fluctuation during spring. Court decrees for storage of 8,140 acre-feet on headwaters of Surface Creek. The release of this flow during irrigation season changes 

natural flow.

ACCURACY. Stage-discharge relation permanent. Rating curve well denned. Operation of water-stage recorder satisfactory except for short periods, as shown in 

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

rating table mean daily gage height obtained by inspection of recorder graph. 

Owing to wide control station is nonsensitive, and records can be considered only 

good.

TJNCOMPAHGRE RIVER AT OTJRAY, COLO.

LOCATION. River: 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 TJncompahgre River above 

river station.

DRAINAGE AEEA. 44 square miles (measured on topographic map).
GBAND KtVBE BASI1SF, 123

RECORDS AVAILABLE. January 25, 1911, to September 30, 1918, for river station and 

February 25, 1916, to September 30, 1918, for power-house flume. Beginning 

October 1,1917, only combined daily flow for river and flume are given, as intermittent operation of latter 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. Fipm January 7 to March 17, 1908, records were kept at dam of Ouray 

Electric Light & Power Co., 1 mile south of present station, and were furnished 

through courtesy of Wheeler & Whinnerah.

GAGE. River: Vertical staff attached to rock cliff at left side of stream 150 feet above 

mouth of Canyon Creek.

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

power house. Both gages read by T. J. Watkins, forest ranger.

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

Flume: Made from footbridge just below gage. »

CHANNEL AND CONTROL. River: Bed composed of small boulders and is rough and 

shifting. Control short distance downstream; slightly shifting during 1918. 

Station is in box canyon with high vertical walls.

Flume: Control is plank nailed across bottom of flume at lower end; permanent elevation of crest, 0.9 foot gage height.

EXTREMES OP DISCHARGE. River: Maximum stage recorded during year, 4.4 feet 

at 8 p. m. June 13 (discharge, 1,180 second-feet). Data insufficient for determining minimum discharge.

ICE. Stage-discharge relation not affected by ice, as warm springs keep stream open.

DIVERSIONS. No diversion above station other than pipe line, whose flow is included 

in these record?.

REGULATION. Diurnal fluctuation during spring, from alternate melting and freezing 

of mountain snow.

ACCURACY. Stage-discharge relation shifted slightly after high water. Fating curve 

well defined below 700 second-feet. Gage read to hundredths once daily except 

period May 13 to June 17, when it was read twice daily. Daily discharge ascertained by applying mean daily gage height to rating table; shifting-control 

method used August 1 to September 30. Records good.

COOPERATION. Gage heights furnished by United States Forest Service.

GRAND RIVER BASIN.

UNCOMPAHGRE RIVER BELOW OtTRAY, COLO.

125

LOCATION. In sec. 30, T. 44 N., R. 7 W. New Mexico principal meridian, near lowest 

bridge in Ouray, Ouray County, a third of a mile below railroad station; below 

all tributaries in Ouray.

DRAINAGE AREA. 76 square miles (measured on topographic map).

RECORDS AVAILABLE. May 12, 1913, to September 30, 1918.

GAGE. Gurley water-stage recorder installed March 28, 1917, referred to vertical 

staff attached to rock cliff, 500 feet above bridge used since March 22, 1916; 

inspected by T. 3. Watkins, forest ranger. Original gage, vertical staff attached 

to downstream side of right bridge abutment, was used prior to March 22, 1916.

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

CHANNEL AND CONTROL. Bed composed of coarse gravel and small boulders; somewhat shifting during 1918. No well-defined control. Banks not subject to 

overflow except above extremely high stage of 6.5 feet.

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

5.5 feet at 1 a. m. June 14 (discharge, 2,530 second-feet); minimum stage, 0.6 

foot at 11 p. m. February 8 (discharge, 17 second-feet).

ICE. Stage-discharge relation not affected by ice, as warm springs keep the river from 

freezing.

DIVERSIONS. All diversions returned to river above station except one of 5.2 secondfeet from Oak Creek.

REGULATION. Diurnal fluctuation during spring, caused by alternate melting and 

freezing of mountain snow.

ACCURACY. Stage-discharge relation not permanent, but shifted after high water. 

Rating curve well defined below 800 second-feet. Operation of water-stage 

recorder satisfactory. Daily discharge ascertained by applying to rating table 

mean daily gage height determined by inspecting gage-height graph; indirect 

method for shifting control used August 21 to September 30. Records good.

Discharge measurements of Uncompahgre River below Ouray, Colo., during the year

ending Sept. 30, 1918.

LITTLE COLORADO RIVER BASIN. 

LITTLE COLORADO RIVER NEAR WOODRUFF, ARIZ.

LOCATION. In T. 16 N., R. 22 E., at highway bridge 1J miles below Woodruff, Navajo County, and 4 miles below Silver Creek.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. December 5, 1915, to September 30, 1918.

GAGE. Stevens continuous water-stage recorder on right bank just below highway 

bridge.

DISCHARGE MEASUREMENTS. Made from bridge or by wading near bridge.

CHANNEL AND CONTROL. Bed consists of bedrock covered with thin deposit of sand 

and silt; shifts considerably because of large quantities of silt that are constantly 

being deposited at low stages and scoured out at each rise. No well-defined 

control. Banks not subject to overflow.

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

2.24 feet at 1 p. m. March 14 (discharge, 337 second-feet); minimum stage probably occurred during period of no record.

1915-1918: Maximum stage, 12.7 feet January 19, 1916 (discharge not determined). Stream dry for about 2 weeks during June and July, 1916.
136 SURFACE WATER SUPPLY, 1918, PART IX.

ICK. Stage-discharge relation not seriously affected by ice.

DIVERSIONS. Much of the low-water flow is diverted for irrigation in vicinity of St.

Johns and Snowflake; amount unknown. 

REGULATION. There are several small reservoirs on headwaters of this stream and

on Silver Creek which regulate the flow to some extent. 

ACCURACY. Stage-discharge relation changed considerably during floods and slightly

at low stages. Standard rating curve fairly well defined below 400 .second-feet

and poorly defined above. Operation of water-stage recorder unsatisfactory.

Daily discharge determined by shifting-control method. Records fair.

VIRGIN RIVER BASIN. 

VIRGIN UTTER AT VIRGIN, UTAH.

LOCATION. In NW. £ sec. 27 or NE. \ sec. 28, T. 41 S., R. 12 W., a few hundred feet 

above point where river enters 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.

RECORDS AVAILABLE. April 18, 1909, to September 30, 1918.

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

February 1, 1915; read by Lawrence Earl. For description of gages at original 

section see Water-Supply Paper 459.

DISCHARGE MEASUREMENTS. Made by wading below gage except during high water 

when old cable above Virgin must be used.

CHANNEL AND CONTROL. Bed consists of sand and gravel. Principal control is a 

gravel bar a short distance below the gage; shifts slightly. Left bank subject to 

overflow.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 7.3 feet at 2.30 

p. m. March 12 (discharge estimated from extension of rating curve, 5,100 secondfeet); minimum stage recorded, 1.62 feet at 7 p. m. July 3 (discharge, 42 secondfeet).

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 

equalled 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 all important diversions.

RE GULATION . None.

ACCURACY. Stage-discharge relation changed during floods. Standard rating curve 

fairly well defined except for peaks of sharp floods. Gage read to hundredths 

once daily about five or six times a week. Daily discharge determined by applying daily gage height to rating table and interpolating for days when gage was not 

read, except for floods, which are roughly estimated. Records poor.

LOCATION. In sec. 3, T. 6 S., R. 30 E., 1,500 feet above Arizona & New Mexico 

Railroad bridge at Guthrie, Greenlee County, and 8 miles above junction of 

Gila and San Francisco rivers.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. November 6, 1910, to July 11, 1918, when station was discontinued.

GAGE. Stevens water-stage recorder on left bank, installed May 16, 1914, at datum 

different from that of inclined staff gage on right bank about 500 feet above railroad bridge, which was used prior to that date; inspected by A. 0. Baker, 

Howard Sprouse, and Willard Marshall.

DISCHARGE MEASUREMENTS. Made from cable 1,000 feet below gage or by wading.

CHANNEL AND CONTROL. Bed composed of sand and gravel; shifts slightly at low 

stages and considerably at high stages. No well-defined control.

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

5.7 feet 12.30 p. m. July 1 (discharge, 2,280 second-feet); minimum discharge, 

24 second-feet, May 13,15, and 26.

1910-1918: Maximum stage recorded, 14.7 feet morning of October 15, 1916 

(discharge not determined); minimum discharge, 18 second-feet, May 21, 1914.

DIVERSIONS. Sufficient water to irrigate about 7,000 acres of land is diverted from 

stream above station.

ACCURACY. Stage-discharge relation not permanent. Standard rating curve fairly 

well defined below 500 second-feet, poorly defined from 500 to 2,400 second-feet, 

and extended above 2,400 second-feet. Shifting-control method used during 

year. Operation of water-stage recorder satisfactory. Records fair.

GILA RIVER NEAR SAN CARLOS, AR.IZ.

. One mile above dam site in box canyon on San Carlos Indian Reservation and 6 miles below San Carlos Indian Agency, Gila County.

DRAINAGE AREA. Not measured. 

RECORDS AVAILABLE. April 29, 1914, to September 30,1918, at present site; July 11, 

1899, to Nov. 27,1905, at point half a mile south of Indian Agency at San Carlos 

and below San Carlos River; August 17, 1910, to February 5, 1911, at point just 

below Arizona Eastern Railroad bridge and half a mile above San Carlos River.

GAGE. Stevens water-stage recorder on left bank 1 mile above dam site.

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

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

Control afforded by rapids over heavy boulders just below gage; shifts somewhat 

because of sand filling in and washing out between boulders.

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

8.84 feet at 9 p. m. August 6 (discharge, 8,630 second-feet); minimum stage, from 

water-stage recorder, 0.26 foot June 12-14 (discharge, 3 second-feet).

1914-1918: Maximum stage, 25.5 feet January 20, 1916 (discharge, from extension of rating curve, about 92,000 second-feet); minimum stage, 0.15 foot July 1, 

1914 (discharge, 1 second-foot).

DIVERSIONS. Water for irrigating about 30,000 acres is diverted from river in valley 

just above station. About 7,000 acres is irrigated from this stream above station 

at Guthrie.

ACCURACY. Stage-discharge relation continually changing. Standard rating curve 

fairly well denned below 14,000 second-feet and poorly denned above. Shiftingcontrol method used during year. Operation of water-stage recorder reasonably 

satisfactory except as indicated in footnote to daily-discharge table. Records 

fair.

from flood marks (discharge, from extension of rating curve, about 93,000 secondfeet); no flow June 29 to July 11, 1913.

DIVERSION'S. About 30,000 acres is irrigated front this stream between this station 

and Guthrie, and about 7,000 acres above Guthrie.

ACCURACY. Stage-discharge relation continually changing. Standard rating curve 

fairly well defined below 30,000 second-feet; poorly defined above. High-water 

discharge measurements subject to considerable error due to impossibility of obtaining accurate soundings. Shifting-control method used during year. Operation 

of water-stage recorder satisfactory except during March when staff gage was used. 

Records fair.

QUEEN CREEK NEAR SUPERIOR, ARIZ.

LOCATION. One mile below dam site near Whitlow's ranch and 12 miles below Superior, Final County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. February 14, 1915, to September 30, 1918. A station was 

operated at Whitlow's ranch during 1896 and fragmentary records of stage and 

flood occurrence kept during 1897 to 1899. Total run-off, January, 1896, to 

August 11,1899, published in Twenty-first Annual Report, Part IV. 

82375 WSP 479 22 11
156 SURFACE WATER SUPPLY, 1918, PART IX.

GAGE. Inclined staff on left bank 1 mile below dam site, installed September 15," 

1916; read by W. C. Mullins and Hart Mullins. Original gage was vertical staff 

painted on rock ledge on right bank at lower end of box canyon about 500 feet 

above Whitlow's ranch house, installed February 14, 1915. For description of 

succeeding gages, see Water-Supply Paper 459.

DISCHARGE MEASUREMENTS. Made from cable at dam site or by wading.

CHANNEL AND CONTROL. Bed composed of sand and gravel which is constantly 

shifting. No well-defined control. Left bank subject to overflow at extremely 

high water.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 8.0 feet at 10.30 

a. m. August 6 (discharge, about 5,000 second-feet); channel dry for long periods 

during year. Floods with considerable greater discharge have occurred during 

previous years, but no reliable record is available showing maximum stage or discharge. Channel at present gage is dry for considerable period each year; at 

dam site 1 mile above gage, discharge seldom, if ever, is less than about 1 secondfoot.

DIVERSIONS. Water diverted above gage to irrigate a few acres; amount unknown.

ACCURACY. Stage-discharge relation not permanent. Rating curve poorly defined. 

Gage read to half-tenths or hundredths twice daily. Daily discharge not accurate enough to publish. Monthly estimates poor but show the deficiency of 

water.

SANTA CRTJZ RIVER NEAR NOGALES, ARIZ.

LOCATION. In SW. % sec. 36, T. 23 S., R. 14 E., just below proposed dam site at 

Yerba Buena ranch, half a mile above city pumping plant, and 7 miles northeast 

of Nogales, Pima County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. March 22 to November 30,1907, and April 1,1909, to September 

30, 1918 (incomplete).

GAGE. Richard Freres' water-stage recorder on left bank about half a mile above 

city pumping plant installed January 3,1916; inspected by W. W. Coons. Original 

gage, a vertical staff on right bank about 500 feet below the intake of a small irrigation ditch and about one-fourth mile above the present gage. For description 

of succeeding gages, see Water-Supply Paper 459.

DISCHARGE MEASUREMENTS. Made by wading.

CHANNEL AND CONTROL. Bed composed of sand and gravel, which is constantly 

shifting. No well-defined control.

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

2.1 feet from noon to 4 p. m. August 7 (discharge, 142 second-feet). No reliable 

records of maximum floods during previous years. Channel is generally dry 

during part of each year.

DIVERSIONS. Water is diverted above station for irrigation of about 140 acres.

ACCURACY. Stage-discharge relation continually changing. Standard rating curve 

defined by 19 discharge measurements made during year from which the changes 

in stage-discharge relation were determined with fair accuracy for low stages. 

Changes during high stages not well defined. Water-stage recorder was not sensitive and gage heights are subject to errors as great as 0.05 foot at any time. Daily 

discharge ascertained by shifting-control method. Records fair for low stages 

and poor for high stages.

Independent datum at each location.
162 SURFACE WATER SUPPLY, 1918, PART IX.

DISCHARGE MEASUREMENTS. Made from cable or by wading.

CHANNEL AND CONTROL. Bed composed of sand and gravel. Control is solid rock; 

permanent.

EXTREMES OF DISCHARGE. 1912-1918: Maximum stage recorded, 15.9 feet, determined from flood marks, December 20,1914 (discharge, determined from extension 

of rating curve, about 18,000 second-feet); minimum discharge recorded, 30 

second-feet at 4 a. m. January 14, 1918.

DIVERSIONS. None.

ACCURACY. Stage-discharge relation permanent. Eating curve well defined from 

40 to 150 second-feet. Operation of water-stage recorder satisfactory, but no observer was available to attend it after Feb. 19. Mean daily gage height determined by inspecting graph from water-stage recorder. Daily discharge below 

300 second-feet ascertained by applying mean daily gage height to rating table; 

above 300 second feet, discharge not determined. Daily gage heights for entire 

period, published. Records good.

SALT RIVER NEAR ROOSEVELT, ARIZ.

LOCATION. At diversion dam for power canal, 10 miles above upper end of Eoosevelt 

reservoir and 20 miles east of Roosevelt, Gila County.

DRAINAGE AREA. 4,222 square milfts (measured by United States Reclamation 

Service.)

RECORDS AVAILABLE. October 1, 1913, to September 30, 1918 (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).
164 SURFACE WATER SUPPLY, 1918, PART IX.

GAGE. Principal gage is a 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 year, 6,120 

second-feet, March 10; minimum discharge, 152 second-feet, September 25.

1913-1918: Maximum mean daily discharge 79,200 second-feet, January 15, 

1916; minimum discharge, 152 second-feet, September 25, 1918.

DIVERSIONS. None.

ACCURACY. Discharge measurements are naade nearly every day when discharge is 

less than about 3,000 second-feet, and 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, and results are subject to considerable error.

COOPERATION. Daily-discharge records furnished by Salt River Valley Water Users' 

Association.

Daily discharge, in second-feet, of Salt River near Roosevelt, Ariz., for the year ending

Sept. SO, 1918.

datum 1.8 feet above original gage; read by Nicholas A. Vyne. Original gage 

was a vertical staff painted on east bridge pier.

DISCHARGE MEASUREMENTS. Made from higli^ay bridge or by wading.

CHANNEL AND CONTROL. Bed composed of clay and sand; shifting during high water. 

No well-defined control. Banks not subject to overflow except at extremely 

high water.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 14.5 feet at 6 p. m. 

March 8; probably some backwater from Beaver Creek, discharge not determined. 

Minimum stage recorded, 0.45 foot June 8-10 (discharge, 38 second-feet).

1912-1918: Maximum stage recorded, 17.0 feet on night of January 18,1916 (dipcharge not determined); minimum discharge, 31 second-feet, June 28 and 29, 1914.

ACCURACY. Stage-discharge relation practically permanent during year, except for 

periods in February and March, when it was affected by backwater from Beaver 

Creek. Rating curve well defined below 3,000 second-feet. Curve used above 

3,000 second-feet based on logarithmic extension and is subject to considerable 

error. Gage read to half-tenths once daily; during high water oftener. Daily 

discharge ascertained by applying mean daily gage height to rating table. Records 

fair for low stages and poor for high stages.

BEAVER CREEK AT CAMP VERDE, ARIZ.

1/ocATioN. In sec. 30, T. 14 N., R. 5 E., a quarter of a mile above junction with 

Verde River and 1 mile northeast of Camp Verde, Yavapai County.

DRAINAGE AREA. Not measured.

HECORDS AVAILABLE. December 1, 1912, to September 303 1918.

<JAGE. Inclined and vertical .staff on right bank, installed August 14, 1916, at same 

datum and at practically isame location as original gage which was washed out 

January 21, 1916; read by Nicholas A. Vyne. From January 22 to August 13, 

1916, temporary gage at datum 1.46 feet above original gage was used. All readings on temporary gage reduced to datum of original gage.

DISCHARGE MEASUREMENTS. Made by wading near gage.

 CHANNEL AND CONTROL. Bed composed of sand, clay, and solid rock; shifts slightly 

at low stages and considerably at high stages. No well-defined control.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 14.2 feet at noon 

March 8 (discharge not determined); minimum discharge, 7 second-feet during 

parts of April, July, and September.

1912-1918: Maximum stage occurred in 1918; minimum discharge, 1.5 secondfeet, April 26-30, 1913.

DIVERSIONS. Water is'diverted for irrigation at several points above station; quantity unknown. A small amount of water is discharged into creek above gage at 

times by an irrigation ditch which diverts from Verde River above the mouth 

of Beaver Creek.

ACCURACY. Stage-discharge relation probably affected by backwater from Verde 

River, during the periods February 25-28 and March 8-13; otherwise practically 

permanent. Rating curve well defined below 50 second-feet and extended above. 

Gage read to half-tenths once daily; during high water oftener. Daily discharge 

ascertained by applying mean daily gage height to rating table. Records fair for 

low stages and poor for high stages.

GILA BrVEK BASIN. 179 

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 AEBA. Not measured.

RECOKDS AVAILABLE. November 10, 1910, to September 30, 1918.

GAGE. Stevens continuous water-stage recorder on right bank, installed October 2, 

1913; destroyed by flood on January 27, 1916, and replaced March 21, 1916; during 

the interval staff-gage readings were made by R. Jones. From August 28, 1913, 

to October 2, 1913, Richard Freres (Paris, France) water-stage recorder was used. 

Prior to August 28, 1913, gages were vertical staffs, either painted on or attached 

to masonry diversion dam, with datum 20 feet lower than that used for waterstage recorders.

DISCHARGE MEASUREMENTS. Made from cable about one-third of a mile below gage 

or by wading near gage.

CHANNEL AND CONTROL. Bed above and below the dam consists of shifting sand and 

gravel. Principal control is formed by the unfinished portion of the diversion 

dam and ledge on which dam is built. At low and medium stages entire stream 

flows through the larger opening in the dam near the right bank. At high stages 

the stream divides and part flows through the opening near the left bank and 

through a scour gate opening in the dam. At extreme high stages the stream 

flows over the entire crest of the dam. This control shifted considerably because 

of the crevices in dam filling in with sand and washing out during high stages. On 

October 18, 1914, an artificial control was completed across the right opening or 

gap in dam but was partly destroyed by flood of January 29, 1915. It was repaired October 28, 1915, but was again partly destroyed during floods of January, 

1916, and April, 1917.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 16.5 feet at 11 

a. m. August 6 (discharge, from extension of rating curve, about 39,600 secondfeet); minimum discharge during year, 2 second-feet, parts of June to September. 

1910-1918: Maximum stage on record, 30 feet January 27, 1916, determined 

from flood marks (discharge from extension of rating curve, about 105,000 secondfeet) ; minimum discharge, 2 second-feet, has occurred at numerous times during 

the period of record.

DIVERSIONS. Water is diverted above gage for irrigating two or three small ranches; 

amount not known.

ACCURACY. Stage-discharge relation not permanent. Standard rating curve fairly 

well defined below 4,000 second-feet. Operation of water-stage recorder satis-, 

factory except as indicated in footnote to daily-discharge table. Daily discharge ascertained by the shifting-control method. Mean daily gage height 

determined by inspecting gage graph or, on days of considerable fluctuation, by 

averaging hourly gage heights. Records fair for low and medium stages; poor for
180 SURFACE WATER SUPPLY, 1918, PART IX.

SURFACE WATER SUPPLY, 1918, PART IX. 183

WHITEWATEE, BASIN. 

WHITEWATER DRAW NEAR DOUGLAS, ARIZ.

ILocATiON. In sec. 10, T. 24 S., R. 27 E., opposite city pumping plant, a quarter of 

a mile above highway bridge, a quarter of a mile above El Paso & Southwestern 

Railroad bridge, 1 mile above electric railway bridge, and about 1} miles west of 

Douglas, Cochise County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE August 24 to October 10, 1911, at electric railway bridge; 

July 21, 1912, to February 15, 1916, at highway bridge; and February 16, 1916, 

to September 30, 1918, at present location.

 GAGE Vertical and inclined staff on right bank opposite city pumping plant; read 

by Mrs. L. E. King and Mrs. Joseph Harris. Original gage installed in August, 1911, 

at electric railway bridge was read until October 10, 1911. On July 21, 1912, 

station was moved three-quarters of a mile upstream to highway bridge. Datum 

was raised 3.00 feet January 20, 1915. February 16, 1916, station was moved a 

quarter of a mile upstream to its present location and gage set at an independent 

datum.

DISCHARGE MEASUREMENTS Made from cable near gage or by wading.

CHANNEL AND CONTROL Bed composed of sand and gravel; shifts frequently. Slag 

dumped into the channel below the gage causes backwater at the gage and scours 

out at high water.

EXTREMES OF DISCHARGE. Maximum stage during year, 8.0 feet July 15 (discharge, 

from extension of rating curve, about 1,050 second-feet); minimum discharge about 

0.2 second-foot between floods.

1911-1918: maximum stage recorded, 13.6 feet at 9 a. m. December 23, 1914 

(discharge, from extension of rating curve, about 3,000 second-feet). Stream 

dry or carries less than 0.5 second-foot the greater part of each year.

DIVERSIONS. Some flood water is diverted above station for irrigation, quantity 

unknown.

ACCURACY. Stage-discharge relation changes frequently. Rating curve denned 

by measurements made during 1919 was used. On days when discharge was 

greater than ordinary seepage flow (about 0.2 second-foot) gage was read twice 

daily to half-tenths and during rapidly fluctuating stages, oftener. On account 

of the extremely flashy character of the flow the assumption that the average of 

the observed gage heights was the mean for the day may cause considerable error. 

Daily discharge determined by applying mean daily gage height to rating table. 

Records fair.
