AUTHORIZATION AND SCOPE OF WORK

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

measurements of flow made on streams in the United States during 

the year ending September 30, 1925.

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. Since the fiscal year ending June 30, 1895, 

successive appropriation bills passed by Congress have carried the 

following items:

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.

In the execution of the work many private and State organizations 

have cooperated, either by furnishing data or by assisting in collecting data. Acknowledgments for cooperation of the first kind are 

made in connection with the description of each station affected; 

cooperation of the second kind is acknowledged on page 9.

Measurements of stream flow have been made at about 5,120 points 

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

Hawaiian Islands. In July, 1925, 1,710 gaging stations were being 

maintained by the Geological Survey and the cooperating organizations. Many miscellaneous discharge measurements were made at 

other points.. In connection with<,thi§ 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.
2 SURFACE WATER SUPPLY, 1925, PART IX 

DEFINITION OF TERMS

The volume of water flowing in a stream the "run-off" or "discharge" is expressed in various terms, each of which has become 

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

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

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

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

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

per square mile, run-off in inches, 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 fuoljaanental 

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.

"Kun-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 of the 

stream channel below the gage which determine the stage-discharge 

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

be the same section or sections at all stages.

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

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

control.

EXPLANATION OF DATA

The data presented in this report cover the year ending September 30, 1925. At the beginning of January in most parts of the 

United States much of the precipitation in the preceding three 

months is stored in the form of snow or ice, or in ponds, lakes, and 

swamps, or as ground water, 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 possi-
EXPLANATION OF DATA 6

bly 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 of 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. The general methods 

are outlined in standard textbooks on the measurements of river 

discharge. A typical gaging station, equipped with water-stage 

recorder and measuring cable and car, is shown in Figure 1.

FIGURE 1. Typical gaging station

From the discharge measurements rating tables are prepared that 

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

heights to these rating tables gives the daily discharge from which 

the monthly and yearly mean discharge is computed.

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

this report comprise a description of the station, a table giving records of discharge measurements, a table showing the daily discharge 

of the stream, and a table of monthly and yearly discharge and 

run-off.

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

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

The description of the station gives, in addition to statements 

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

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

stream for log driving, shifting of control, and the cause and effect 

of backwater; it gives also information as to diversions that decrease 

the flow at the gage, artificial regulation, maximum and minimum 

recorded stages, and the accuracy of the records.

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

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

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

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 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 per 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 gives information 

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

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

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

the daily discharge.

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

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

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

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

individual measurements with reference to the mean rating curve.

The monthly means for any station may represent with high 

accuracy the quantity of water flowing past the gage, but the fig-
PUBLICATIONS 5

ures 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/' published in the earlier reports, should be used with 

caution because of possible inherent sources of error not known to 

the Geological Survey.

Many gaging stations on streams in the irrigated areas of the 

United States are situated above most of the diversions from those 

streams, and the discharge recorded does not show the water supply 

available for further development, as prior appropriations below the 

stations must first be satisfied. To give an idea of the amount of 

prior appropriations, a paragraph on diversions is presented in each 

station description. The figures given can not be considered exact 

but represent the best information available.

The tables of monthly discharge give 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.

PUBLICATIONS

Investigation of water resources by the United States Geological 

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

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

it has comprised also investigation of such closely allied subjects as 

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

of waters. Most of the results of these investigations have been 

published in the series of water-supply papers, but some have appeared 

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

The results of stream-flow measurements are now published annually in 12 parts, each part covering an area whose boundaries 

coincide with natural drainage features as indicated below:

Part I. North Atlantic slope basins (St. John River to York River).

II. South Atlantic slope and eastern Gulf of Mexico basins (James River to 

the Mississippi).

III. Ohio River Basin.

IV. St. Lawrence River Basin.

V. Upper Mississippi River and Hudson Bay Basins.

VI. Missouri River Basin.

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

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

An index of the reports containing records obtained prior to 1904 

has been published in Water-Supply Paper 119.

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

1922. The data for any particular station will be found in the 

reports covering the years during which the station was maintained. 

For example, data for Machias River at Whitneyville, Me., 1903 to 

1921, are published in Water-Supply Papers 97, 124, 165, 201, 241, 

261,281,301,321,351, 381,401,431,451,471,501, and 521, which contain records for the New England streams from 1903 to 1921. Results

RECOEDS AVAILABLE. January 1, 1900, to September 30, 1925; also May 12 to 

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

GAGE. Friez water-stage recorder on right bank in front of power house; installed May 17, 1910; inspected by C. H. Oberly. Prior to that date, a 

staff gage referred to same datum was used.

DISCHAEGE MEASUEEMENTS. Made from cable beneath State Street Bridge, a 

third of a mile below gage.

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

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

 intervals. Banks not subject to overflow except at extremely high stages.

EXTEEMES OF DISCHAEGE. Maximum stage during year from water-stage recorder, 8.06 feet at noon May 31 (discharge, 11,200 second-feet); minimum 

stage, 1.85 feet at 3 p. m. November 16 (discharge, 120 second-feet).

1900-1925: Maximum stage recorded, 12.55 feet at noon June 14 and 15, 

1918 (discharge, 30,100 second-feet); minimum stage, 1.6 feet at 5 p. m. 

February 6, 1921 (discharge, 80 second-feet).

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

river open.

DIVEESIONS. Between this station and Hot Sulphur Springs, diversions for 

irrigation of a few hundred acres.

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

controls flow during day at low water, but has insufficient pondage to control it for more than a few hours.

ACCURACY. Stage-discharge relation slightly shifting. Rating curves used 

October 1 to December 20 and December 21 to September 30 are both well 

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

ascertained by applying to rating table meai> daily gage height obtained by 

inspection of recorder graph; shifting-control method used October 21 toDecember 20 and January 29 to April 5. Records good.

COLORADO RIVER NEAR CISCO, UTAH

LOCATION. In NW. M sec. 17, T. 23 S., R. 24 E., 1 mile below mouth of Dolores 

River, 15 miles by road south of Cisco, Grand County, and 90 miles above 

confluence with Green River.

DRAINAGE AREA. 24,100 square miles (measured on General Land Office map).

RECORDS AVAILABLE. November 10, 1914, to September 30, 1917, and October 

1, 1922, to September 30, 1925; October 1, 1913, to November 10, 1914, 

25 miles downstream at Moab; flow about same at both places.

GAGE. Au continuous water-stage recorder on left bank half a mile above suspension highway bridge; installed December 7, 1922; inspected by G. C. 

Brown. Same datum as in 1917.

DISCHARGE MEASUREMENTS. Made from cable 400 feet below gage.

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

below station. Left bank high and not subject to overflow; right bank in 

extreme floods is Overflowed between station and bridge. Bed composed of 

sand and gravel. Low-water control is at a riffle, believed to be ledge rock, 

a quarter of a mile below gage; fairly permanent.
14 SURFACE WATER SUPPLY, 1925, PAET IX

EXTREMES OF DISCHARGE. Maximum stage during year, 9.86 feet at noon June 1 

(discharge, 28,200 second-feet); minimum stage not recorded, occurred 

during ice-affected period (by hydrographic comparison, discharge was 1,500 

second-feet or less).'

1915-1917; 1923-1925: Maximum stage, 19.7 feet at 9 p. m. June 19, 

1917 (discharge, 76,800 second-feet); minimum stage, 1.14 feet at 8 p. m. 

September 3, 1924 (discharge, 844 second-feet).

ICE. Stage-discharge relation affected by ice.

DIVERSIONS. Below practically all diversions. A. large amount of water is 

diverted in Colorado for irrigation.

REGULATION. Station is too far below to be affected, except in a general way, 

by regulation in Colorado.

ACCURACY. Stage-discharge relation practically permanent; slight shifting, 

believed to be caused by temporary deposits of sediment on control; affected 

by ice December 20 to March 7. Standard rating curve well defined. Operation of water-stage recorder satisfactory except December 10-13, March 14- 

16, May 29, 30, June 9,10, July 28, 29, and September 10-12. Daily discharge 

determined by applying to rating table mean daily gage height ascertained 

from recorder graph or staff gage readings; shifting-control method used 

May 21-31, June 17-22, September 5-7, and 22-24. Discharge during iceaffected periods and periods of missing gage height estimated by hydrographic 

comparison with Colorado River stations in Colorado and Lees Ferry station 

in Arizona. Records good except for estimated periods during winter, for 

which they are fair.

COLORADO RIVER AT LEES FERRY, ARIZ.

LOCATION. At Lees Ferry, just above mouth of Paria River, at head of Marble 

Gorge, and at lower end of Glen Canyon, Coconino County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. June 13, 1921, to September 30, 1925.

GAGE. Continuous water-stage recorder installed January 19, 1923, on left 

bank at head of Paria riffle. Zero of gage is 3,106.35 feet above sea level. 

Recorder inspected by J. E. Klohr and D. H. Barber, resident hydrographers.

DISCHARGE MEASUREMENTS. Made from cable about 1 mile upstream.

CHANNEL AND CONTROL. Channel at measuring section straight and fairly 

uniform. Banks high and not subject to overflow. Bed composed of sand 

and silt and is scoured several feet during each flood season. Channel at 

gage confined between banks not subject to overflow. Control is Paria 

riffle, composed of gravel and boulders.

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

recorder, 13.6 feet at 9.15 a. m. June 3 (discharge, 54,900 second-feet); 

minimum stage, 4.2 feet at 5 p. m. December 27 (discharge, 750 secondfeet); river frozen over.
16 SURFACE WATER SUPPLY, 1925, PART IX

1921-1925: Maximum stage recorded, 26.5 feet at 2 p. m. June 18, 1921 

(discharge, about 190,000 second-feet); minimum discharge occurred on 

December 27; 1924.

The high-water mark of the flood of 1884 at the ranch near the mouth of 

Paria River, as identified by Jerry Johnson, is at elevation 3,137.1 feet above 

sea level.

ICE. Stage-discharge relation affected by ice.

DIVERSIONS. Water is diverted from main river and tributaries above station 

for irrigation of about 1,500,000 acres.

RE GULATION. None.

ACCURACY. Stage-discharge relation remained practically permanent from 

beginning of record until about September 20, 1925, when a change in 

control was caused by a series of sharp freshets; affected by ice December 

24 to February 6. During the year 62 discharge measurements, well distributed with respect to time and stage of river, were made. Rating curves 

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

discharge ascertained by applying to rating table mean daily gage height 

determined from recorder graph, except for period of ice effect for which 

daily discharge was estimated from ten discharge measurements and a 

detailed comparison with discharge at the Grand Canyon station where no 

ice occurred. Records good. '

" COLORADO RIVER AT BRIGHT ANGEL CREEK, NEAR GRAND CANYON, ARIZ.

LOCATION. 300 feet above Kaibab Bridge, Grand Canyon National Park, a 

quarter of a mile above Bright Angel Creek, and 11 miles by trail northeast 

of Grand Canyon, Coconino County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. October 1, 1922, to September 30, 1925.

GAGE. Continuous water-stage recorder in concrete shelter and stilling well on 

right bank; inspected by B. S. Barnes and R. G. Kasel, resident hydrographers. Zero of gagp is 2,420.3 feet above sea level.

DISCHARGE MEASUREMENTS. Made from cable 20 feet upstream from gage.

CHANNEL AND CONTROL. Channel at gage and measuring section is 275 feet 

wide at low water and 300 feet at high water. Bed is silt and sand which 

scours and fills each season. Control is Bright Angel Creek rapids.

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

recorder, 18.75 feet at 10 p. m. June 3 (discharge, 53,700 second-feet); 

minimum stage, 0.70 foot at 8 p. m. December 28 (discharge, 700 secondfeet).

1923-1925: Maximum stage recorded, 28.5 feet at 6 p. m. September 19, 

1923 (discharge, 112,000 second-feet); minimum discharge occurred on 

December 28, 1924.

ICE. No ice has occurred at this station during the period of record.

DIVERSIONS. Water is diverted from main river and tributaries above station 

for irrigation of about 1,500,000 acres.

REGULATION. None.

ACCURACY. Stage-discharge relation remained practically permanent after the 

flood of September, 1923, until about August 27, 1925. A series of sudden 

freshets of short duration in August and September, 1925, caused a slight 

scouring of control. During the year 51 discharge measurements were 

made, well distributed with respect to both time and river stage. Rating 

curves are well defined. Operation of water-stage recorder satisfactory. 

Daily discharge ascertained by applying to rating table mean daily gage 

height determined from recorder graph. Records good.

COLORADO RIVER NEAR TOPOCK, ARIZ.

LOCATION. At lower end of a narrow section of Mohave Canyon, 3 miles below 

Topock, Mohave County.

DRAINAGE AKEA. 171,000 square miles.

RECORDS AVAILABLE. February 1, 1917, to September 30, 1925.

GAGE. Continuous water-stage recorder on left bank; inspected by D. A. Dudley, W. C. Chase, J. A. Baumgartner, and J. E. Klohr, resident hydrographers. 

Zero of gage is 423.2 feet above sea level (new determination of sea level 

elevation; gage datum unchanged).
COLORADO EIVER AND TRIBUTARIES ABOVE GREEN RIVER 19

DISCHARGE MEASUREMENTS. Made from cable 20 feet upstream from gage.

CHANNEL AND CONTROL. Channel is straight above and below gage. Banks 

are rock and have steep slopes. Bed is composed of sand and silt and shifts 

continually. The control is indefinite.

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

recorder, 14.70 feet at 8 a. m. June 6 (discharge, 51,200 second-feet); minimum discharge, 1,800 second-feet at 8 a. m. January 4.

1917-1925: Maximum stage recorded, 28.2 feet at 6 a. m. June 22, 1921 

(discharge, 174,000 second-feet); minimum discharge occurred on January 4, 

1925.

DIVERSIONS. Water is diverted from main river and tributaries above station for 

irrigation of about 1,500,000 acres.

REGULATION. None.

ACCURACY. Stage-discharge relation continually changing. Complete discharge 

measurements made three times a week or oftener, October 1 to April 30, 

and on alternate days, May 1 to September 30. On intervening days, with 

few exceptions, short-cut discharge measurements were made. These shortcut measurements consisted of complete soundings throughout the measuring 

section and complete velocity observations at eight key points in the crosg 

section by means of which the discharge for the measurements was computed 

using well-defined coefficients. Operation of water-stage recorder satisfactory. Daily discharge ascertained by shifting-control method, using the 

mean daily gage height determined from recorder graph. Records good.

COLORADO RIVER AT YUMA. ARIZ.

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

meridian, 100 feet upstream from original Southern Pacific Railroad bridge 

and half a mile downstream from highway bridge at Yuma, Yuma County. 

Since the change in channel on June 7, 1920, Gila River enters from the 

east 5 miles upstream from this station.

DRAINAGE ABE A. 242,000 square miles (measured on map compiled from best 

available maps of the Colorado River Basin).

RECORDS AVAILABLE. April 1, 1878, to September 30, 1925. Gage heights only 

prior to January 1, 1902.

GAGE. Long-distance water-stage recorder installed May 1, 1922. Sender in 

stilling well on left bank 100 feet upstream from original Southern Pacific 

Railroad bridge. Continuous recorder in office of Bureau of Reclamation. 

Sender and recorder inspected daily by Dan Martinez. Prior to installation 

of recorder vertical staff at same location and datum. Zero of gage is 102.79 

feet above mean sea level.

DISCHARGE MEASUREMENTS. Made from cable 1,100 feet downstream from gage.

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

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

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 23.45 feet 

at 9 p. m. June 8 (discharge, 53,200 second-feet); minimum stage, 13.71 

feet at noon January 8 (discharge, 1,150 second-feet).

1902-1925: Maximum mean daily discharge, 240,000 second-feet January 

22, 1916; minimum discharge, 1,150 second-feet on January 8, 1925.

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

tributaries. Some water is diverted out of the drainage basin above this 

station. Water for the Yuma project of the United States Bureau of Reclamation is diverted from right side of river at Laguna Dam 15 miles upstream. Canal siphons under river at Yuma. Wasteway from canal returns 

water to river on right side half a mile below gaging station. Imperial 

Irrigation District diverts water from river on right side 7 miles downstream 

from this station.

REGULATION. Flow temporarily affected at times by sluicing at Laguna Dam. 

Storage on tributaries has very little effect on flow at this station.

ACCURACY. Stage-discharge relation continually changing. Discharge measurements made on alternate days, except Sundays, throughout year, with measurements made daily except Sunday during October. No measurements 

were made during the period January 24 to February 9, because of fire
COLOBAB0 RIVER AND TEITOTAIIISS ABOVE GBEEN EIVBE 21

damage to measuring cable. Operation of waters-stage recorder satisfactory 

except January 25 to February 19, when recorder was removed owing to fire; 

staff readings used during this period. Daily discharge ascertained by 

shifting-control method, using the mean daily gage height determined from 

recorder graph. Discharge for period January 24 to February 9 estimated 

from hydrographic comparison with Colorado River near Topock, consideration being given to variation in diversion at L^guna Dam. 

COOPERATION. Station operated by United States Bureau of Reclamation. 

Records furnished by Bureau of Reclamation and reviewed and checked 

by Geological Survey.

discharge, 523 second-feet at 6 a. m. October 2 and 3.

1917-1925: Maximum stage recorded, 14.95 feet at 8 a. m. and noon May 

23, 1920 (discharge, 35,700 second-feet); minimum discharge, 155 secondfeet September 6, 1924.

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

DIVERSIONS. Below all diversions from Gunnison River and tributaries. Most 

of water diverted through Redlands Canal is for pumping and is returned 

to Colorado River below mouth of the Gunnison.

COMBINED FLOW. Combined flow of Gunnison River and Redlands power 

canal represents flow of Gunnison River that enters Colorado River, less 

about 25 second-feet, which is used during irrigation season.

ACCUBACY. Stage-discharge relation shifts at intervals; affected by ice. Rating 

curves for river used October 1 to December 9 and December 10 to September 

30 are both well defined; for canal, not well defined. Gages read to halftenths twice daily. Daily discharge ascertained by applying mean daily 

gage height to rating table; shifting-control method was used for canal 

October 1 to December 10. Records for river good; for canal poor.

UNCOMPAGHRE RIVER BELOW OTJRAY, COLO.

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 ABE A. 76 square miles (measured on topographic map).

RECORDS AVAILABLE. May 12, 1913, to September 30, 1925.

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 W. S. Doran. Original gage, vertical staff attached to downstream side%of right bridge abutment, used prior to March 22, 1916.

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

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

Control is broken rock ledge 50 feet downstream on which mill tailings are 

alternately deposited and scoured out. Banks not subject to overflow except 

at extreme high-water stage of 6.5 feet.

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

recorder, 4.92 feet at 7 p. m. July 20, due to cloudburst in Canyon Creek 

(discharge, 1,340 second-feet); minimum stage, 0.70 foot 4 to 9 a. m. January 

29 (discharge, 16 second-feet).

1913-1925: Maximum discharge recorded, 2,530 second-feet at 1 a. m. 

June 14, 1918; minimum discharge, 10 second-feet February 5 and 6, 1915, 

March 18, 1922, and January 21, 1923.

ICE. Stage-discharge relation not affected by ice; warm springs keep river open.

DIVERSIONS. Practically all diversions returned to river above station.

REGULATION. Diurnal fluctuation during spring caused by alternate melting 

and freezing of mountain snow. Intermittent operation of power pipe line 

above station causes sudden fluctuation in discharge for short periods.

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

curve fairly well defined. Operation of water-stage recorder satisfactory 

except as explained in footnote to table of daily discharge. Daily discharge 

ascertained by applying to rating table mean daily gage height obtained by 

inspection of recorder graph, using shifting-control method March 16 to 

Ju^y 25. Records fair.

GAGE. Bristol float-type water-stage recorder at right abutment; inspected by 

Bureau of Reclamation employee.

DISCHARGE MEASUREMENTS. Made from bridge.

CHANNEL AND CONTROL. Bed composed of silt and gravel. Control shifts during 

high water. Banks not subject to overflow.

EXTREMES OF DISCHARGE. Maximum stage during year from water-stage recorder, 4.4 feet at 8 a. m. July 5 (discharge, 1,740 second-feet); minimum stage 

recorded, 0.64 foot April 3 and 4 (discharge, 45 second-feet).

1903-1925: Maximum discharge recorded, 2,490 second-feet at 7.30 p. m. 

June 12, 1921; minimum discharge recorded since diversion through Gunnison Tunnel began in 1910, 7 second-feet on several days during July, 1910.

ICE. No data, as records are discontinued during winter.

DIVERSIONS. Ditches above station divert normal flow during irrigation season; 

records represent chiefly return seepage water.

REGULATION. (See diversions.)

ACCURACY. Stage-discharge relation shifts at intervals. Well-defined rating 

curves used October 1 to August 24, August 25 to September 19, and September 23-30. 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, using shiftingcontrol method October 1 to. November 30. Records good.

COOPERATION. Field data furnished by United States Bureau of Reclamation.

GREEN RIVER AT GREEN RIVER,' UTAH

LOCATION. In NW. % SW. }i sec. 15, T. 21 S., R. 16 E., at highway bridge 

1 mile southwest of Green River, Emery County. San Rafael River enters 

Green River 22 miles downstream.

DRAINAGE AREA. 40,600 square miles.

RECORDS AVAILABLE. October 21, 1894, to October 15, 1899; February 16, 

1905, to December 31, 1911; June 21, 1924, to September 30, 1925. Records 

obtained at Little Valley, 7 miles downstream, December 18, 1910, to June 

20, 1924, give practically the same flow.

GAGE. Stevens continuous water-stage recorder on bridge pier near right bank, 

installed September 19, 1924; inspected by H. T. Howland.

DISCHARGE MEASUREMENTS. Made from cable at old ferry site, 7 miles below

CHANNEL AND CONTROL. Bed composed of gravel and sand. One channel at all 

stages. Left bank high, not subject to overflow; right bank lower, may be 

overflowed at extreme stages. However, water is confined by highway and 

Denver & Rio Grande Western Railroad bridges. There is a well-defined 

break in slope 1,000 feet below gage.

EXTREMES OF DISCHARGE. Maximum stage during year, 10.04 feet at 11 p. m. 

May 26 (discharge from extension of rating curve, 20,600 second-feet); 

minimum stage not recorded.

1894-1899; 1905-1925: Maximum discharge recorded, 68,800 second-feet 

May 29, 1897; minimum stage, 0.95 foot December 1, 1919 (discharge, 

510 second-feet).

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

DIVERSIONS. Below practically all diversions.

REGULATION. Slight regulation by diversion from tributaries.

ACCURACY. Stage-discharge relation changed several times during year; affected 

by ice December 22 to March 5. Normal rating curve well defined. Operation of water-stage recorder satisfactory during year except March 7 and 8. 

Daily discharge ascertained by applying to rating table mean daily gage 

height determined from recorder graph, making parallel shifts to all measurements. Discharge estimated for periods of no gage heights and during iceaffected period from temperature records, two meter measurements, and observer's notes or by comparing combined flow of Green River and Colorado 

River near Cisco with Colorado River at Lees Ferry. Daily discharge good, 

estimated periods fair.

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

Described in earlier reports as near "Blake" or " Elgin."

Duchesne, Duchesne County, three-quarters of a mile above mouth of Indian 

Canyon Creek, a small tributary entering from south, and 1J^ miles above 

confluence of Strawberry and Duchesne Rivers.

DBAINAGE AREA. 1,040 square miles (measured on topographic map).

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

1914, to September 30, 1925.

GAGE. Enameled vertical staff installed June 13, 1922, on downstream side of 

right abutment of bridge; read by E. S. Winslow.

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

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

below gage. Bed of sand and fine gravel. Natural channel about 50 feet 

wide is constricted at bridge to 36 feet. Banks comparatively low; covered 

with underbrush; left bank subject to overflow at very high stages. Gravel 

riffle 200 feet below gage; fairly permanent.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 7.7 feet at 

7 p. m. July 2 (discharge, 1,200 second-feet); minimum stage, 4.05 feet July 19, 

20, August 1, 2, and 6-9 (discharge, 37 second-feet).

1908-1925: Maximum stage recorded, 7.7 feet (old datum) May 27, 1922 

(discharge, 3,230 second-feet); minimum discharge, 30 second-feet, November 20, 1914. Records obtained prior to 1914 incomplete.

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

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

acre-feet) about 40 miles above station, is diverted by tunnel to Spanish 

Fork Basin. Some water is also diverted from upper end of Strawberry 

Valley to basin of Provo River.

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

ACCURACY. Stage-discharge relation changed slightly during winter and returned 

to normal July 1; affected by ice December 12 to March 8. Rating curve 

well defined. Gage read to half-tenths twice a day. Daily discharge ascertained by applying mean daily gage height to rating table using parallel shifts 

to measurements March 9 to June 30. Discharge for ice-affected periods estimated from one discharge measurement, temperature records, observer's notes 

and by hydrographic comparison with all Duchesne River stations. Records 

good.

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 rarely affected by ice.

DIVERSIONS. Above all important diversions.

REGULATION. None.

ACCURACY. Stage-discharge relation variable; affected by ice about December 

21-28. Rating curve poorly defined. Gage read to hundredths four or five 

times a week. Daily discharge ascertained by applying gage height to rating 

table and interpolating or estimating discharge for days when gage was not 

read. Records poor.

The following discharge measurements were made:

April 24, 1925: Gage height, 2.90 feet; discharge, 206 second-feet.

August 22, 1925: Gage height, 2.83 feet; discharge, 75.4 second-feet.

SANTA CLARA CREEK NEAR CENTRAL, UTAH

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

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

Valley. Hunts Spring, which has fairly constant discharge of about 3 

second-feet, enters 40 feet below gage.

DEAINAGE ABE A. 84 square miles (measured on topographic map).

RECOBDS AVAILABLE. April 21, 1909, to September 30, 1925.

GAGE. Vertical enamel staff nailed to cottonwood tree on left bank about 50 

feet above bridge; read by Mrs. R. H. Hunt. Datum of gage was raised 

0.45 foot January 20, 1910; 2.00 feet February'22, 1916, and lowered 1.00 

foot August 12, 1918.

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

CHANNEL AND CONTROL. Stream bed consists of gravel and sand. Banks fairly 

high but may be overflowed at extreme stage; one channel at all stages. A 

riffle formed by small boulders 40 feet below gage is fairly permanent. Point 

of zero flow at gage height 0.7 foot ± 0.1 foot, determined June 9f 1923.
86 SURFACE WATER SUPPLY, 1925, PART IX

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 2.2 feet at 

4 p. m. September 18 (discharge, 157 second-feet); minimum stage, 0.98 

foot September 12, 14, 16, and 17 (discharge, 5 second-feet).

1909-1925: Maximum stage recorded, 5.00 feet at 11 a. m. October 6, 

1916 (discharge, 1,450 second-feet); minimum stage, 0.82 foot January 8, 

1920 (discharge, 4 second-feet).

ICE. Stage-discharge relation seldom affected by ice.

DIVERSIONS. The New Castle Reclamation Co. has a reservoir on Grass Valley 

Creek, with a capacity of 23,000 acre-feet. Water is diverted into reservoir 

from Santa Clara Creek above town of Pine Valley and exchanged for direct 

flow taken by tunnel through rim of the Great Basin for irrigation of lands 

outside the Colorado River Basin, Central Canal diverts water about 2 

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

measured when it was carrying 16 second-feet.

REGULATION. Flow affected by the diversions and storage above.

ACCURACY. Stage-discharge relation permanent during year. Rating curve well 

defined. Gage read to hundredths once daily three or four times a week. 

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

interpolating discharge for days when gage was not read, except September 

18 and 19, when heavy rains occurred and discharge was estimated from a 

study of precipitation data. Records fair.

The following discharge measurements were made:

April 25, 1925: Gage height, 1.16 feet; discharge, 10.4 second-feet.

August 21, 1925: Gage height, 1.08 feet; discharge, 7.6 second-feet.

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

of rating curve); minimum discharge, July 4, 1923, 26 second-feet.

DIVERSIONS. Station is above diversions for irrigation in Safford Valley, except 

Brown Canal which diverts water 1 mile above station for irrigating 820 

acres. Brown Canal wasteway returns some water to river below this 

station. About 14,000 acres are irrigated from Gila River and tributaries 

above Safford Valley

REGULATION. None except by diversions for irrigation.

ACCURACY. Stage-discharge relation continually changing. Standard rating 

curve well defined to 10,000 second-feet, poorly defined above. Operation 

of water-stage recorder satisfactory. Daily discharge ascertained by 

applying mean daily gage height to rating table or by taking mean of hourly 

discharges obtained by applying hourly mean gage height to rating table; 

shifting-control method used October 1 to July 23, August 25-30, and 

September 15-30. Records good.

QUA RIVER NEAR SAN CARLOS, AEIZ.

LOCATION. In T. 3 S., R. 18 E., unsurveyed, half a mile above San CarlOs dam 

site on San Carlos Indian Reservation and 6^ miles west of San Carlos, 

Gila County. San Carlos River enters on right 8 miles upstream.

DRAINAGE AREA. 12,900 square miles (measured on topographic maps).

RECORDS AVAILABLE. April 29, 1914, to September 30, 1925. July 11, 1899, 

to November 27, 1905, at point half a mile south of 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. Water-stage recorder installed July 3, 1924, on right bank, 500 feet 

downstream from previous recording gage.

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

CHANNEL AND CONTROL. Bed composed of sand, gravel, and boulders. Banks 

not subject to overflow. Low-water channel well defined, always open to 

gage well. Riffle 800 feet below station. High-water control formed by 

narrowing of walls and sharp bend at dam site.

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

recorder, 14.1 feet at noon September 4 (discharge, 14,400 second-feet); minimum stage, 0.91 foot at 9 p. m. October 2 (discharge, 0.3 second-foot).

1914-1925: Maximum discharge about 130,000 second-feet 2 January 20, 

1916 (stage about 28.0 feet, present gage); river dry June 28 to July 1,1919.

* Previously published as 92,000 second-feet. Revised figure is based on rating for Kelvin station determined from measurements of flood in 1926.
GILA EJVER BASIN 91

DIVERSIONS. About 38,000 acres are irrigated frorn Gila River and tributaries 

above this station.

REGULATION. None except by diversions for irrigation.

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

well de/fined to 2,000 second-feet, fairly well defined to 20,000 second-feet. 

Operation of water-stage recorder satisfactory. Daily discharge ascertained 

by applying mean daily gage height to rating table, or by averaging hourly 

discharge; shifting-control method used November 14 to July 27, August 

1-26, and September 23-30. Records good.

GELA RIVER AT KELVIN, ARIZ.

LOCATION. In sec. 12, T. 4 S., R. 13 E., 1,000 feet below mouth of Mineral 

Creek, a quarter of a mile below concrete highway bridge, a mile west of 

Kelvin, Final County, 15 miles below mouth of San Pedro River, and 15 miles 

above Ashurst-Hayden Dam.

DRAINAGE AREA. 18,100 square miles (measured on topographic maps and 

Greenidge map of Sonora, Mexico).

RECORDS AVAILABLE. January 26, 1911, to September 30, 1925.

GAGE. Water-stage recorder on left bank; installed June 15, 1914; new stilling 

well and shelter installed June 17, 1924. No change in datum of gage.

DISCHARGE MEASUREMENTS. Made from highway bridge a quarter of a mile 

above gage or by wading.

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

shifting. Banks not subject to overflow. Gravel riffle 300 feet below gage.

EXTREMES OF DISCHARGE. Maximum stage during year from water-stage recorder, 6.9 feet at 2.30 a. m. September 4 (discharge, 11,200 second-feet); 

minimum stage from water-stage recorder, 1.25 feet occurred on June 3, 9, 

10, 13, 14, and 18 (discharge, 0.7 second-foot).

1911-1925: Maximum stage recorded, 19.5 feet about noon January 20, 

1916, determined from floodmarks (discharge from extension of rating curve, 

about 132,000 second-feet 8); no flow June 29 to July 11, 1913.

DIVERSIONS. Station is above diversions for "Florence-Casa Grande Valley. 

About 38,000 acres are irrigated from Gila River above this station. Acreage 

irrigated from San Pedro River not known.

REGULATION. None except by diversions for irrigation.

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

well defined to 20,000 second-feet and fairly well defined above. Operation 

of water-stage recorder satisfactory. Daily discharge ascertained by applying daily mean gage height to rating table or by averaging the hourly discharge; shifting-control method used for entire year. Records good.

8 Previously published as 93,000 second-feet. Revised figure is based on rating determined from measurements of flood in 1926.

NOTE. Gage heights in above table show head on crest of dam. No water over crest of dain during 

months and days for which no record is given.
GILA BIVEB BASIN 

QUA RIVER AT GIILESPIE DAM. AKIZ.

LOCATION. In SE. M NB. M sec. 28, T. 2 S., R. 5 W., at GiUespie Dam, Mancopa County. Hassayampa River enters on right 8 miles upstream. Gila 

River enters Colorado River 150 miles downstream. There are no large 

tributaries between Gillespie Dam and mouth of Gila River.

DRAINAGE ABBA. 48,100 square miles (measured on topographic maps and 

Greenidge map of Sonora, Mexico).

RECORDS AVAILABLE. August 4, 1921, to September 30, 1925.

GAGE. Water-stage recorder on left wing wall 10 feet upstream from crest of 

Gillespie Dam, installed July 28, 1924. Zero of gage at mean elevation of 

crest of dam, and at elevation 753.8 feet above mean sea level. Prior to 

iaetaUation of recorder, records were obtained by Gila Water Co. by measuring height of water on crest at left end of dam.

DISCHARGE MEASUREMENTS. Made by wading on apron below dam or in river 

channel half a mile downstream.

CHANNEL AND CONTROL. Bed composed of silt filled in above dam about level 

with eresft, except along face of dam and near left bank where bed is kept 

below crest by sluicing. Bed above dam probably scours during floods. 

There are two sluice gates at left end of dam behind the long wing wall, on 

the river side of which the gage is attached. The gates of the Gila Water 

Co.'s canal are also situated against the left bank behind this wing wall. 

Gage height is affected by sluicing for a short period each day at various times 

during the year.

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

recorder, 2.30 feet at 12.30 a. m. September 20 (discharge, 15,200 second-feet); 

no flow over dam on various days during year.

1921-1925: Maximum stage recorded, 6.0 feet December 28, 1923 (discharge, 70,000 second-feet); no flow over dam during various periods each 

year.

DIVERSIONS. Water diverted from Gila River by Gillespie Dam. When water 

is below crest of dam a gate is kept open which turns a small quantity of 

water downstream to satisfy prior rights. About 275,000 acres are irrigated 

from Gila River and tributaries above this dam.

REGULATION. None except by irrigation diversions and by gates of dam.

ACCURACY. Stage-discharge relation permanent. Principal rating curve is based 

on fifteen discharge measurements made during 1925 and 1926 and is well 

defined from 100 to 10,000 second-feet. From 10,000 to 150,000 second-feet 

the rating has been extended by using the formula lor broad-crested weirs, Q =» 

2.64 LHJ, and assumed velocities of approach based on observed conditions. 

Below 100 second-feet the rating varies somewhat on account of accumulation of moss or trash on crest. For this principal rating, gage heights at 

recorder station are used. Principal rating curve is used for the period 

November 11 to September 30. Rating for the period October 1 to November 10 is based on one discharge measurement made April 25, 1924, and on 

extension of principal rating above discussed. It is not well defined. Gage 

height for this measurement was obtained by direct measurement of depth of 

water on crest at left end of dam and was affected by draw down at crest. 

Operation of water-stage recorder satisfactory except for period October 1 

to November 10, when clock was stopped. Depth of water on crest at left 

end of dam read once each day to nearest quarter-inch during this period. 

Readings of depth of water on crest are affected by draw down at crest. 

For the period October 1 to November 10, daily discharge ascertained by 

applying to rating table for that period the daily readings of depth of wjater
96 SURFACE WATER StfPPLY, 1925, PART IX

on crest of dam. For the period November 11 to September 30, daily dis 

charge ascertained by applying to rating table for that period the mean daily 

gage height or by averaging the hourly discharge. Records good. 

COOPERATION. Gage-height record October 1 to November 10 furnished by 

Gila Water Co.

SALT BITER NEAR CHRYSOTHE, ARIZ.

LOCATION. In SE. % sec. 5, T. 5 N., R. 18 E., on San Carlos Indian Reservation 

at Big Peninsula Bend, near Chrysotile, Gila County. Black River joins 

White River to form Salt River 15 miles upstream, and Cibecue Creek 

enters on right 8 miles downstream.

DRAINAGE AREA. 3,050 square miles (measured on topographic maps).

RECORDS AVAILABLE. September 18, 1924, to September 30, 1925.

GAGE. Water-stage recorder on left bank, installed October 2, 1924. Staff 

gage used September 18 to October 1, 1924.

DISCHARGE MEASUREMENTS. Made from cable 100 feet downstream from gage 

or by wading.

CHANNEL AND CONTROL. Bed composed of bedrock and deposits of gravel 

and silt, which scour and fill. Banks not subject to overflow. Bedrock 

riffle and falls 400 feet below gage. Extreme high-water control formed 

by narrowing of rock side walls a quarter of a mile below gage.

EXTREMES OP DISCHARGE. Maximum stage recorded during period of records, 

6.5 feet at 11.30 p. m. March 8 (discharge, 6,550 second-feet); minimum 

stage recorded, 1.48 feet on December 27 (discharge, 127 second-feet).
134 SURFACE WATER SUPPLY, 1925, PART IX

ICE. Practically no ice forms at this station.

DIVERSIONS. Only minor diversions above this station.

RE GUL ATION. None.

ACCURACY. Stage-discharge relation permanent above 1,500 second-feet, but 

for lower discharge, not permanent because of filling and scouring of silt in 

channel between gage and principal control. Rating curve well defined 

between 150 and 8,000 second-feet and extended above and below. Operation of water-stage recorder satisfactory. Staff gage read twice a day to 

hundredths September 18 to October 1, 1924. Daily discharge ascertained 

by applying mean daily gage height to rating table or from hourly discharge 

for days of considerable range in stage; shifting-control method used September 18 to October 6, December 1 to April 20, May 9-13, and July 22 

to September 30. Records good.

COOPERATION. Permittee of Federal Power Commission project No. 425 

furnished results of 20 discharge measurements.
