SURFACE WATER SUPPLY OF THE COLORADO 

RIVER BASIN, 1926

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, 1926.

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 8.

Measurements of stream flow have been made at about 5,250 points 

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

Hawaiian Islands. In July, 1926, 1,730 gaging stations were being 

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

1
2 SURFACE WATER SUPPLY, 1926, PART IX

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 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 fundamental 

unit from which others are computed.

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

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

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

regards time and area.

"Run-off in inches" is the depth to which an area would be 

covered if all the water flowing from it in a given period were 

uniformly distributed on the surface. It is used for comparing 

run-off with rainfall, which is usually expressed in inches.

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

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

The following terms not in common use are here defined.

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

of gage height to discharge."

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

stream below the gage which determines 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 gag^ height at which water ceases to flow over the

control.

EXPLANATION OF DATA .

The data presented in this report cover the year beginning October 

1, 1925, and ending September 30, 1926. At the beginning of Janu-
EXPLANATION OF DATA " - &

ary 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 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

FIGUKE 1. Typical gaging station

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. The general methods are 

outlined in standard textbooks on the measurement of river discharge. A typical gaging station, equipped with water-stage recorder and measuring cable and car, is shown in Figure 1.

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 

results of discharge measurements, a table showing the daily discharge of the stream, and a table of monthly and yearly discharge 

and run-off.
4 SURFACE WATER SUPPLY, 1926, PART IX

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 condition that may affect the permanence of the stage-discharge relation, covering such subjects as the occurrence of ice, the use of the 

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

backwater; it gives also information as to diversions that decrease 

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

recorded stages, and the accuracy of the records.

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

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

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

fluctuation the discharge obtained from the rating table and the 

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

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

mean daily discharge may be obtained by averaging discharge at 

regular intervals during the day or by 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 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.
PUBLIOATIONB 5

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

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

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 main 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" 

published in earlier reports by the Geological Survey should be used 

with caution because of possible inherent but unknown sources of 

error.

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 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.

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, underground 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 bulletins, professional papers, annual reports, and 

monographs.

The records at most of the stations discussed in these reports 

extend over a series of years, and miscellaneous measurements at 

many points other than regular gaging stations have been made 

each year. An index of the reports containing records obtained 

prior to 1904 has been published in Water-Supply Paper 119.

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

1922. The data for any particular station will, as a rule, 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 of miscellaneous measurements are published 

by drainage basins.

COLORADO RIVER AT GLENWOOD SPRINGS, COLO.

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

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

Fork enters half a mile below.

DRAINAGE AREA. 4,560 square miles (measured on base map of Colorado).

RECORDS AVAILABLE. January 1, 1900, to September 30, 1926, 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; inspected by C. H. Oberly and Andrew Dickson.
COLORADO RIVER AND TRIBUTARIES ABOVE GREEN RIVER 13

DISCHARGE MEASUREMENTS. Made from cable beneath State Street bridge, 

a third of a mile below gage.

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

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

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

EXTREMES OP DISCHARGE. Maximum discharge occurred when water-stage 

recorder was not operating. By comparison with record of Roaring Fork 

at Glen wood Springs the mean daily discharge was estimated at 22,700 

second-feet on June 7; minimum stage, 2.1 feet from 7 to 11 a. m. December 

30 and 31 (discharge, 200 second-feet).

1900-1926: Maximum stage recorded, 12.55 feet at noon June 14 and 15, 

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

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

ICE. Stage-discharge relation nat affected by ice. Hot water from springs 

keeps river open. ,

DIVERSIONS. Between this station and Hot Sulphur Springs, water is diverted for 

irrigation of a few hundred acres.

REGULATION. Shoshone power plant of Public Service Co., 7 miles upstream, 

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

it for more than a few hours.

ACCURACY. Stage-discharge relation practically permanent; not affected by 

ice. Rating curve well defined. Operation of water-stage recorder satisfactory except as explained in footnote to daily-discharge table. Daily 

discharge ascertained by applying to rating table mean daily gage height 

obtained by inspection of recorder graph except from November 20 to April 

5 when daily discharge was computed from bihourly discharge on account of 

diurnal fluctuations. t Records excellent except for period of missing gage 

height, for which they are fair.

COLORADO RIVER NEAR CISCO, UTAH

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

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

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, 1926; 25 miles downstream at Moab October 1,. 

1913, to November 10, 1914; flow about the same at both places.

GAGE. Au continuous water-stage recorder on left bank half a mile above 

suspension highway bridge; inspected by G. C. Brown and Frank Hittle.

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 a riffle a quarter of a mile below 

gage; fairly permanent.

EXTREMES OF DISCHARGE. Maximum stage during year, 15.20 feet at 4 p. m. 

May 27 (discharge, 52,400 second-feet); minimum stage, 1.16 feet at 5 

a. m. September 27 (discharge, 1,430 second-feet).

1915-1917; 1923-1926: Maximum stage, 19.7 feet at 9 p. m. June 19, 

1917 (discharge, 76,800 second-fefft); 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 downstream to be affected, except in a general 

way, by regulation in Colorado.

ACCURACY. Stage-discharge relation practically permanent except for slight 

shifting caused by temporary deposits of sediment on control; affected 

by ice January 1 to February 11. Standard rating curve well defined. 

Operation of water-stage recorder satisfactory except as stated in footnote 

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

table mean daily gage height or by shifting-control method. Discharge 

during ice-affected periods and periods of missing gage height estimated 

by hydrographic comparison with flow at stations in Colorado and at Lees 

Ferry in Arizona. Records good except for estimated periods for which 

they are fair.

COLORADO RIVER AT IEES 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, 1926.
18 SURFACE WATER SUPPLY, 1926, PART IX

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 D. A. Dudley and Jerry Johnson or Elmer Johnson.

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 is composed of 

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

gage confined between banks that are not subject to overflow. Control is 

Paria riffle; composed of gravel and boulders.

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

recorder, 16.7 feet at 8 a. m. May 29 (discharge, 86,500 second-feet); minimum stage from water-stage recorder, 6.16 feet at 9 p. m. September 10 

(discharge, 3,100 second-feet).

1921-1926: Maximum stage recorded, 26.5 at 2 p. m. June 18, 1921 

discharge, about 190,000 second-feet); minimum stage, 4.2 feet at 5 p. m. 

December 27, 1924 (discharge, 750 second-feet); river frozen over.

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 altitude of 3,137.1 feet 

above sea level.

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

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 practically permanent during year, except 

for slight changes at the beginning of the spring floods and more changeable 

conditions during the short periods of maximum discharge. Rating curves 

well defined below 72,000 second-feet, but not satisfactory above. During 

the year 39 discharge measurements were made, of which 27 were made 

during the period of the spring floods, April 16 to July 12. Operation of 

water-stage recorder satisfactory, except August 18-19. Daily discharge 

ascertained by applying to rating table mean daily gage height determined 

from recorder graph, except for periods indicated in footnote to table of 

daily discharge and for a few days when hourly discharge was used because 

of rapidly changing stage. Records good.

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, 1926. 

GAGE-. Water-stage recorder in concrete shelter and stilling well on right bank.

Inspected by B. S. Barnes, D. H. Barber, W. E. Code, and K. C. McCarter,

resident hydrographers. Zero of gage 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 ranges from

a width of 250 feet at low water to 325 feet at high water. Banks are solid

rock and very high. 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, 24.27 feet at 2.30 p. m. May 29 (discharge, 85,600 second-feet);

minimum stage, from water-stage recorder, 2.14 feet at 1 a. m. September 12

(discharge, 3,810 second-feet).

1923-1926: Maximum stage recorded, 28.5 feet at 6 p. m. September 19,

1923 (discharge, 112,000 second-feet); minimum stage, 0.70 foot at 8 p. m.

December 28, 1924 (discharge, 700 second-feet).
20 SURFACE WATER SUPPLY, 1926, PART IX

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. *t

REGULATION. None.

ACCURACY. Stage-discharge relation changed to some extent during period of 

high water in May. Rating curves very well defined by 74 discharge 

measurements made during the year and well distributed with respect to 

both time and river stage. Operation of water-stage recorder satisfactory. 

Daily discharge ascertained by applying to rating table mean daily gage 

height determined from recorder graph. Records excellent.

COLORADO RIVER NEAR TOPOCE, ARIZ.

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

Topock, Mohave County.

DRAINAGE AREA. 171,000 square miles.

RECORDS AVAILABLE. February 1, 1917, to September 30, 1926.

GAGE. Continuous water-stage recorder on left bank; inspected by J. A. Baumgartner, K. C. McCarter, and J. E. Klohr, resident hydrographers. Zero 

of gage is 428.2 feet above sea level.

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

CHANNEL AND CONTKOL. 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, 19.80 feet at 2.30 a. m. June 1 (discharge, 84,800 second-feet); 

minimum stage recorded, 4.66 feet at 11 p. m. September 13 (discharge, 

3,390 second-feet).

1917-1926: Maximum stage recorded, 28.2 feet at 6 a. m. June 22, 1921 

(discharge, 174,000 second-feet); minimum discharge, 1,800 second-feet 

at 8 a. m. January 4, 1925.

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

for irrigation of about 1,500,000.acres.

REGULATION. None.

4ccuKACY. Stage-discharge relation continually changing. Discharge measurements made on alternate days throughout year. Measurements also made 

on intervening days when there was rapid change in stage. Measurements 

were made each day August 25 to September 30. Operation of waterstage recorder satisfactory. 'Daily discharge ascertained by shiftingcontrol method by applying to standard rating table mean daily gage 

height determined from recorder graph. Records good.

COLORADO RIVER AT YUMA, ARIZ.

LOCATION. In NE. K 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 east 5 

miles upstream from this station. 

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

available maps of the Colorado River Basin).

RECORDS AVAILABLE. April 1, 1878, to September 30, 1926. 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 at same point as vertical staff gage formerly used. 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 discharge during year, 73,100 second-feet 

on June 16 (stage, 25.18 feet); maximum stage, 26.65 feet at 1 p. m. June 6. 

Minimum stage, 15.90 feet at 7 p. m. September 16 (discharge, 2,130 secondfeet).

1902-1926: Maximum daily mean 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 in 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.
COLORADO RIVER AND TRIBUTARIES ABOVE GREEN RIVER 23

ACCURACY. Stage-discharge relation continually changing. Discharge measurements made on alternate days except Sundays throughout year. Beginning 

January, 1926, discharge measurements made with equipment and methods 

similar to those used at other gaging stations on Colorado River. Operation 

of water-stage recorder satisfactory, except November 7-13 and December 15 

to January 31, when staff readings were used. Staff gage read twice each day 

throughout year. Daily discharge ascertained by shifting-control method 

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

recorder graph.

 COOPERATION. Station operated by United States Bureau of Reclamation.

GUNNISON RIVER NEAR GRAND JUNCTION, COIO.

LOCATION. In NW. % sec. 35, T. 1 S., R. 1 W., half a mile below Redlands Co.'s 

canal and 2 miles above mouth of Gunnison River, in Grand Junction, Mesa 

County; below all tributaries.

DRAINAGE AREA. 8,020 square miles (measured on base map of Colorado).

RECORDS AVAILABLE. April 1, 1917, to September 30, 1926. From October 19, 

1894, to December 21, 1895, and May 2, 1897, to September 30, 1899, station maintained nearer mouth.

GAGE. Slope gage at left bank a quarter of a mile below canal intake; read by 

employee of Redlands Co.

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

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

high and not subject to overflow.

EXTREMES OF DISCHARGE. Combined flow: Maximum stage recorded during 

year, 8.95 feet 6 p. m. June 7 (discharge, 14,200 second-feet); minimum discharge, 327 second-feet September 3.

1917-1926: 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 power 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 which enters Colorado River, less about 

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

ACCURACY. River and canal: Stage-discharge relation not permanent. Rating 

curves fairly well defined. Gages read to half-tenths twice daily. Daily 

discharge for river and canal ascertained by applying mean gage height to 

rating tables except period April 6 to August 20, when shifting control method 

was used for river. Combined daily discharge ascertained by adding the 

, daily discharge of river and canal. Records fair.

ITNCOMPAHGRE RIVER BEIOW OITRAY, COIO.

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, 1926.

GAGE. Gurley water-stage recorder installed March 28, 1917, referred to vertical staff, attached to rock cliff 500 feet above bridge; inspected by F. A. Rice.

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 OP DISCHARGE. Maximum stage during year, from water-stage recorder, 5.1 feet at 10 p. m. June 6 (discharge, 1,320 second-feet); minimum 

stage, 0.92 foot at 8 a. m. April 2 (discharge, 20 second-feet).

1913-1926: Maximum discharge recorded, 2,530 second-feet at 1 a. m. 

June 14, 1918 (gage height, 5.5 feet); 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 aH 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 decrease in discharge for short periods.

ACCURACY. Staj^diseharge relation not permanent; not affected by ice. 

Rating etHwe fairly well defined. Operation of water-stage recorder satisfactory except for periods as explained in footnote to daily-discharge table. 

Daily discharge ascertained by shifting-control method except October 

1-4 and February 11 to March 5, when mean gage-height obtained by 

inspection of recorder graph was applied to rating table. Records fair.

LOCATION In NW. Ji SW. % sec. 15, T. 21 S., R. 16 E., at highway bridge 1 mile 

southeast of Green River, Emery County. San Rafael River enters from 

right 22 miles downstream.

DRAINAGE ABBA. 40,600 square miles (measured on base maps).

RECORDS AVAILABLE. October 21,1894, to October 15, 1899; February 16, 1905, 

to December 31, 1911; June 21, 1924, to September 30, 1926. Records 

obtained at Little Valley, 7Bailes*tl6WE»trea;'m, December 18, 1910, to June 

20, 1924, give practically the same flow.

'GAGE. Stevens continuous water-stage recorder on downstream side of bridge 

pier near right bank, installed September 19, 1924; inspected by H. T. 

Howland.

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

gage.

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

all stages. Left bank high and not subject to overflow; right bank lower and 

may be overflowed at extreme stages. However, water is confined by highway and Denver & Rio Grande Western Railroad bridges. There is a welldefined break in slope three-quarters of a mile downstream.

EXTREMES OP DISCHARGE. Maximum stage during year, 10.67 feet at 10 p. m. 

May 26; maximum discharge, 24,500 second-feet May 9; minimum stage, 4.84 

feet at 1 p. m. December 20 (discharge, 1,140 second-feet).

1894-1899;'lW5iil'926: Maximum*dfedfctomge retft»cted,*68^800'sffcond^f0et 

May 29, 1897; minimum stage recorded, 0.95 foot on December 1, 1919 

(discharge, 510 second-feet).

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

DIVERSIONS. Below practically all diversions.

.REGULATION. Some regulation due to irrigation.

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

affected by ice December 20-31 and January 4 to February 4. Standard 

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

during year except from August 12 to September 4, during which time two 

daily readings were obtained. Daily discharge ascertained by applying to 

rating table mean daily gage height; shifting-control method used October 

1-5 and May 9 to September 30. Gage heights during ice-affected period 

were only affected for part of each day; discharge for this period ascertained 

by computing an effective gage height and applying it to rating curve. 

Records good.

"COOPERATION. Since December 16, 1917, station has been maintained in cooperation *with Utah Power & Lig*yp©o.

ACCURACY. Stage-discharge relation changed during winter arid again on August 

10. Normal rating curve well defined. Gage read to hundredths four or 

five times a week from October 1 to May 5 and daily for the remainder of 

year. Daily discharge ascertained by applying mean daily gage height to 

rating table, using two parallel shifts. Discharge estimated or interpolated 

for days of missing gage heights. Records fair.

STRAWBEEEY RIVER AT DUCHESNE, UTAH

LOCATION. In SW. Y* NE. % sec. 2, T. 4 S., R. 5 W., Uinta special base and 

meridian, at Winslow ranch, three-quarters of a mile west of post office 

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

Indian Canyon Creek, a small tributary entering from south, and \Y% miles 

above confluence with Duchesne River.

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

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

1914, to September 30, 1926.

GAGE. Enameled vertical staff 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.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 7.0 feet at 

7 a. m. August 10 (discharge, 1,270 second-feet); minimum stage, 4.05 feet 

at 7 p. m. July 26 (discharge, 33 second-feet).

1908-1926: Maximum stage recorded, 7.7 feet (old datum) on 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. 50,000 to 75,000 acre-feet of water from Strawberry Valley 

Reservoir (capacity, 250,000 acre-feet), about 40 miles above station, is 

diverted annually by tunnel to Spanish Fork drainage 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 not permanent. Two rating curves are 

fairly well defined. Gage read to half-tenths twice a day. Daily discharge 

ascertained by applying mean daily gage height to rating table. Discharge 

for ice-affected periods estimated from one discharge measurement, temperature records, observer's notes, and hydrographic comparison with all Duchesne River stations. Records fair.

1900-1903; 1907-1926; maximum stage, 9.4 feet June 22 and 23, 1917 

(discharge, 4,350 second-feet); minimum discharge July 24, 1916, probably 

zero.

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

DIVERSIONS. No diversions below station; several canals of the United States 

Indian Service and some privately-owned canals divert above for irrigation. 

Some return water from irrigation enters a short distance above station.

REGULATION. Flow affected by irrigation diversions.

ACCURACY. Stage-discharge relation permanent; affected by ice during winter. 

Rating curve well defined. Water-stage recorder operated satisfactorily 

except as stated in footnote to daily-discharge table. Daily discharge ascertained by applying mean daily gage height to rating table. Discharge for 

periods of missing gage height and periods of ice effect estimated by comparison 

with records for Duchesne River stations or interpolated. Daily discharge 

good; estimated periods fair.

PRICE EIVER NEAR HELPER, UTAH

LOCATION. In SE. ^ sec. 36, T. 13 S., R. 9 E., at highway bridge three-quarters 

of a mile above diversion dam of Price River Irrigation Co., 2 miles south of 

Helper, Carbon County, and 3 miles below Spring Creek.

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

RECORDS AVAILABLE. February 21, 1904, to September 30, 1926.

GAGE. Chain gage on highway bridge; inspected by D. S. Rowley.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Bed of stream composed of gravel and sand. Control is a riffle of gravel and cobbles.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 9.4 feet at 

11 a. m. October 5 (discharge determined from extension of rating curve, 

1,400 second-feet); minimum stage recorded, 6.48 feet September 22-28 

(discharge, 9 second-feet).

1904-1926: Summer floods occur nearly every year and often greatly 

exceed any recorded stage. Maximum stage recorded, for which discharge 

was determined, 8.43 feet at 9 p. m. June 25, 1917 (discharge determined 

from extension of rating curve, 8,500 second-feet); minimum discharge, 

4 second-feet during December, 1905, January, 1906, and August 8, 1925.

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

DIVERSIONS. Main diversions from Price River are below station.
GREEN RIVER BASIN 71

REGULATION. Flow regulated after May, 1926, by storage reservoir on Fish 

Creek, which is main tributary to Price River.

ACCURACY. Stage-discharge relation changed several times during year. Standard rating curves fairly well defined. Gage read to hundredths once daily 

with occasional omissions and twice daily during periods of rapidly changing 

stage. Daily discharge ascertained by applying mean daily gage height to 

rating table using shifting-control method. Discharge for periods of ice 

effect estimated from temperature records, observer's notes, and one meter 

measurement. Discharge interpolated or estimated from observer's notes 

for days for which no gage heights were obtained and for small flood October 

4-6. Records fair.

HUNTHTGTON GREEK NEAR HUNTINGTON, UTAH

LOCATION. In SE. % sec. 6, T. 17 8., R. 8 E., at old Cunha ranch, 7 miles northwest of Huntington, Emery County. Below all main tributaries, except 

Fish Creek.

DRAINAGE AREA. 188 square miles (measured on Forest Service map, 1920).

RECORDS AVAILABLE. May 3, 1909, to September 30, 1926; fragmentary.

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

Joseph Cunha.

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

CHANNEL AND CONTROL. Bed composed of gravel and sand. Control of coarse 

gravel; fairly permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 4.45 feet at 

4 pr. m. September 11 (discharge, 755 second-feet); minimum stage, 1.24 feet 

at 7 p. m. November 5 (no flow, probably caused by ice jam above).

1909-1926: Maximum discharge, 1,340 second-feet at 9.30 p. m. May 25,

1920. and at 11 p. m. May 25, 1922. Discharge may have been greater in

1921. Minimum stage, 1.24 feet at 7 p. m. November 5, 1926 (no flow, probably caused by ice jam above).

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. Several small ditches from tributaries above station.

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

controls distribution of flow to a slight extent.

ACCURACY: Stage-discharge relation changed slightly at low-water stages. Rating curves well defined between 30 and 700 second-feet; extended above. 

Operation of water-stage recorder satisfactory except during winter. Daily 

discharge ascertained by applying to rating tables mean daily gage height 

determined from recorder graph. Records good except for winter estimates, 

which are fair.

PARIA RIVER BASIN 

PARIA RIVER AT LEES FERRY, ARIZ.

LOCATION. On unsurveyed land half a mile above mouth and a mile northwest 

of Lees Ferry, Coconino County. Paria River enters Colorado River at 

Lees Ferry.

DKAINAGE AREA. 1,520 square miles (measured on topographic maps).

RECORDS AVAILABLE. November 22, 1923, to September 30, 1926.

GAGE. Vertical staff gage on left bank installed October 13, 1925; read by Jerry 

and Elmer Johnson. Prior to October 13, a slope gage 2,000 feet upstream 

was used.

DISCHARGE MEASUREMENTS. Made by wading near gage.

CHANNEL AND CONTROL. Channel straight for 100 feet above and several hundred feet below gage. Right bank is earth of former flood plain, now cultivated farm land and not subject to overflow. Left bank is high rock cliff. Bed 

composed of sand and gravel. Gravel riffle 30 feet downstream from gage 

forms low-water control. Extreme high water in Colorado River may cause 

backwater for a short period at a time of year when discharge of Paria River 

is low and uniform.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 17.5 feet at 

5 p. m. October 5 (discharge, 16,100 second-feet); minimum stage, 0.30 foot 

on June 25 (discharge, 1 second-foot).

1924-1926: Maximum stage recorded, 17.5 feet at 5 p. m. October 5, 1926 

(discharge, 16,100 second-feet); minimum discharge, probably zero on several nights of December and January for years ending September 30, 1924 

and 1925, when river was frozen solid.

ICE. Some ice is apt to occur each winter at this station.

DIVERSIONS. About 1,000 acres irrigated from Paria River. Station is below 

all diversions.

REGULATION. None.

90720 30 6
76 SURFACE WATER SUPPLY, 1926, PART IX

ACCURACY. Gaging station destroyed by flood on October 5. New station 

2,000 feet downstream installed October 13. A discharge measurement by 

surface floats made during the flood on October 5 and later referenced to the 

gage installed October 13 bridges this gap in the record. Stage-discharge 

relation at the new station permanent except for slight changes for low stage. 

Rating curves well defined below 100,second-feet and extended to 16,100 

second-feet as measured on October 5. Gage read to hundredths once a day 

except for some omissions of one or more days October to May as indicated 

in footnote to table of daily discharge. Additional readings made during 

periods of floods. Daily discharge ascertained by applying daily gage 

height to rating table. Discharge interpolated or estimated for days when 

gage was not read. Discharge for days of floods are poor. Records good.

LITTLE COLORADO RIVER BASIN 

LITTLE COLORADO RIVER AT GRAND FALLS, ARIZ.

IIOCATION. In T. 24 N., R. 11 E., unsurveyed, on Navajo Indian Reservation 

at Grand Falls, 38 miles northeast of Flagstaff, Coconino County. Clear Creek 

enters from left about 60 miles upstream. Moenkopi Wash enters from right 

about 40 miles downstream. Little Colorado River enters Colorado River 

70 miles below this station.

DRAINAGE ARfcA. 22,100''square miles (measured on topographic maps).

RECORDS AVAILABLE. November 15, 1925, to September 30, 1926.

GAGE. Water-stage recorder on left bank, 1,000 feet downstream from Grand 

Falls, installed January 5, 1926. Staff gage used November 15, 1925, to 

January 4, 1926.

DISCHARGE MEASUREMENTS. Made from cable 663 feet downstream from gage 

or by wading near gage.

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

silt. Banks not subject to overflow. Rock riffle about 200 feet downstream 

from gage. High-water control is rock channel extending several miles below 

station and is not subject to appreciable change.

EXTREMES OF DISCHARGE. Maximum stage recorded during period November 

15, 1925, to September 30, 1926, 22.5 feet at 9 a. m. September 27 (discharge, 

21,600 second-feet); minimum discharge, no flow on various days throughout 

the period.

ICE. River freezes over at gage for short periods during December and January 

when weather is coldest and when river is very low. Backwater from ice is 

for the most part negligible.

DIVERSIONS. Water diverted for irrigation in upper basin. Acreage irrigated 

above this station not known. No diversions below this station.

REGULATION. None.

ACCURACY. Stage-discharge relation permanent, except for discharge below 50 

second-feet, when scouring and filling of sand may affect velocity of approach 

to control. Rating curve well defined from 50 to 4,000 second-feet; extended 

above. Operation of water-stage recorder satisfactory except as shown in 

footnote to daily-discharge table. Staff gage read twice a day to hundredths 

November 15 to January 4. Daily discharge ascertained by applying daily 

mean gage height to rating table or from hourly discharge for days of considerable range in stage, except as noted in footnote to daily-discharge table. 

Records good.

SANTA CIARA CREEK NEAR CENTRAL, UTAH

LOCATION. In sec. 11, T. 39 S., R. 16 W., just above bridge at R. H. Hunt 

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.

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

RECORDS AVAILABLE. April 21, 1909, to September 30, 1926.

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

feet above bridge; read by Mrs. R. H. Hunt.

DISCHARGE 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 stages; one channel at all 

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

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 2.00 feet at 

4 p. m. April 19 (discharge, 105 second-feet); minimum stage recorded, 

0.96 foot January 7, 9, 11, and 19 (discharge, 4 second-feet).

1909-1926: Maximum stage recorded, 5.00 feet at 11 a. m. October 6, 

1916 (discharge, 1,450 second-feet); minimum discharge, 4 second-feet 

January 8, 1920, and January 6-11 and 19, 1926.

ICE. Stage-discharge relation seldom affected by ice.

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

Creek. Water is diverted, into reseryoir from Santa Clara Creek above 

town of Pine Valley and when available is exchanged for direct flow 

diverted into a tunnel through rim of the Great Basin for irrigation of lands 

outside the Colorado River Basin. The Central Canal diverts water about 

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

has been measured when it was carrying 16 second-feet.

REGULATION. Flow affected by the diversions and storage above.

ACCURACY. Stage-discharge relation shifted slightly during high water. Rating 

curves fairly well defined. Gage read to hundredths once daily three or 

four days a week. Daily discharge ascertained by applying daily gage 

height to rating table and interpolating discharge for days when gage was 

not read. Records fair.

The following discharge measurements were made: 

December 13, 1925: Gage height, 1.15 feet; discharge, 9.2 second-feet. 

May 6, 1926: Gage height, 1.64 feet; discharge, 46.4 second-feet. 

June 11, 1926: Gage height, 1.24 feet; discharge, 16.6 second-feet.

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

recorder, 11.9 feet at 10.30 p. m. April 6 (discharge, 9,960 second-feet): 

no flow July 8-10, August 31, and September 3-10.

1914-1926: Maximum stage, 25.5 feet January 20, 1916 (discharge 

estimated, 130,000 second-feet); minimum discharge, no flow June 28 to 

July 1, 1919, and July 8-10, August 31, September 3-10, 1926.

above this station.

ACCURACY. Stage-discharge relation not permanent; probably fairly permanent 

for high stages but changed for low stages by each flood. Daily discharge 

ascertained by shifting-control method. Records good.

Records of discharge for certain high-water periods in the years ending September 30, 1915 and 1916, revised on basis of a comparison, by means of hydrographs, of discharge at the San Carlos station with the discharge at the stations 

on Gila River near Solomonsville and at Kelvin, are given in the table on page 

90. The revised records for the Kelvin station, published in this report and based 

on discharge measurements of the flood in 1926, were used in revising the records 

for the San Carlos station.

QUA RIVER AT GIL1ESPIE DAM, ARIZ.

LOCATION. In SE. % NE. % sec. 28, T. 2 S., R. 5 W., at Gillespie Dam, Maricopa 

County. Hassayampa River enters from right 8 miles upstream.

DRAINAGE AREA. 48,100 square miles.

RECORDS AVAILABLE. August 4, 1921, to September 30, 1926.

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 753.8 feet above mean sea level.

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

recorder, 3.95 feet at 6 a. m. September 30 (discharge, 38,300 second-feet); 

minimum stage, crest of dam dry on various days during year.

1921-1926: Maximum stage recorded, 6.0 feet on December 28, 1923 

(discharge, 70,000 second-feet); minimum stage, crest of dam dry for 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 is irrigated from 

Gila River and tributaries above this dam.

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

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

has been extended by using formula for broad-crested weirs, Q = 2.64L£Tf, 

and assumed velocities of approach based on observed conditions. Below 

100 second-feet rating varies somewhat on account of accumulation of moss 

or trash on crest of dam. Water discharged through sluice gates, separately 

computed, and included in daily discharge. Records good.

SALT RIVER NEAR CHRYSOTILE, ARIZ.

LOCATION. In SE. J4 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 about 15 miles upstream, and Cibecue Creek

' enters from right 8 miles downstream.

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

RECORDS AVAILABLE. September 18, 1924, to September 30, 1926.

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

DISCHARGE MEASUREMENTS. Made from cable 100 feet downstream from gage 

or by wading half a mile downstream from gage.

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 OF DISCHARGE. Maximum stage recorded during year, 8.5 feet at 

9 p. m. April 6 (discharge, 10,900 second-feet); minimum stage recorded^ 

1.60 feet at 1 a. m. September-11 (discharge, 150 second-feet).

1925-1926: Maximum stage recorded, 8.5 feet at 9 p. m. April 6, 1926 

(discharge, 10,900 second-feet); minimum stage recorded, 1.48 feet on 

December 27, 1924 (discharge, 127 second-feet).
GILA RIVER BASIN 131

ICE. Practically no ice forms at this station.

DIVERSIONS. Only minor diversions above this station.

REGULATION. None.

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

not permanent for lower discharge 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 except May 20-25, when float 

was on mud. Daily discharge ascertained by applying mean daily gage 

height to rating table or, for days of considerable range-in stage, by averaging 

the hourly discharge; shifting-control method used October 1 to March 25 

and May 27 to September 30. Discharge interpolated May 20-25. Records 

good.
