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 in the West. 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 10.

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 the Survey and the cooperating organizations. 

Many miscellaneous discharge measurements were made at other 

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

2 SURFACE WATER SUPPLY, 1926, PART XII B

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

and water power in many sections of the country and will be madeavailable 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 becomeassociated 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. Theprincipal terms used in this series of reports are second-feet, secondfeet per square mile, run-off in inches, and acre-feet. They may bedefined 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 asregards 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 uniformlydistributed 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 quantityrequired 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 beginning October 

1, 1925, and ending September 30, 1926. At the beginning of January in most parts of the United States much of the precipitation 

in the preceding three months is stored as ground water, in the form
EXPLANATION OF DATA &

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

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

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

Tun-off is possibly a small quantity in the ground; therefore the runoff 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 

«tage, measurements of discharge, and general information used to 

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

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

that gives a continuous record of the fluctuations. Measurements of

 discharge are made with a current meter. The general methods are

FIGURE 1. Typical gaging station

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 

lieights 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 yeaily 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.
4 SURFACE WATER SUPPLY, 1926, PART XII B

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 

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 pi ammeter 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 

permanency 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.
PUBLICATIONS 0

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

individual measurements with reference to the mean rating curve.

The monthly means for any station may represent with high 

accuracy the quantity of water flowing past the gage, but the figures 

showing discharge per square mile and run-off in inches may be 

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

concerning water diverted for irrigation or other use, or by inability 

to interpret the effect of artificial regulation of the flow of the river 

above the station. "Second-feet per square mile" and "run-off in 

inches" are therefore not computed if such errors appear probable. 

The computations are also omitted for stations on streams draining 

areas in which the annual rainfall is less than 20 inches. All figures 

representing "second-feet per square mile" and "run-off in inches" 

published in the earlier reports by the Survey should be used with 

caution because of possible inherent sources of error not known to 

the 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, 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, monographs, professional papers, and 

annual reports.

8 SURFACE WATER SUPPLY, 1926, PART XII B

The records at most of the stations discussed in these reports 

extend over a series of years, and miscellaneous measurements at 

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

1926. 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 Kiver 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.

SNAKE RIVER NEAR HEISE, IDAHO

LOCATION. In sec. 5, T. 3 N., R. 41 E., 600 feet above Anderson Dam, Bonneville 

County, 3 miles above Heise, and 25 miles below site of station formerly 

maintained near Lyon. Several small creeks enter between old site and 

present station.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. September 25, 1910, to September 20, 1926.
14 SURFACE WATER SUPPLY, 1926, PART XII B

GAGE. Friez water-stage recorder on left bank; observers, Smith and Kremer.

DISCHAEGE MEASUREMENTS. Made from cable 150 feet below gage.

CHANNEL AND CONTROL. Bed composed of rock ledge, coarse gravel, and cobble- 

 stones. One channel at all stages. Control formed by Anderson Dam, 

parts of which washed out during the high-water periods of 1917 and 191& 

but have been replaced.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 6.59 feet 

4 to 6 a. m. May 25 (discharge, 19,000 second-feet); minimum stage recorded, 1.58 feet February 19 and 28 (discharge, 2,340 second-feet). Minimum discharge recorded, 2,310 second-feet at 2 p. m. December 30 (gage 

height, 2.46 feet).

1910-1926: Maximum discharge recorded, about 52,000 second-feet June 

16, 1918; minimum discharge, probably less than 2,100 second-feet during 

ice-affected period in December, 1924.

ICE. Stage-discharge relation affected by ice.

DIVERSIONS. No large diversions above station. A small ditch having a 

capacity of about 25 second-feet diverts just above station.

REGULATION. Flow controlled to a large extent by storage in Jackson Lake 

Reservoir.

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

25 to February 3, February 14 and 15. Two rating curves used during 

year, one from October 7 to January 26 and the other from January 27 to 

May 20 and June 24 to September 30, are fairly well defined. Staff gage 

read to hundredths once-daily December 29 to February 28; operation of 

water-stage recorder satisfactory for rest of year. Daily discharge ascertained by applying mean daily gage height to rating table, except for period 

of ice effect during which it was estimated from discharge measurements, 

observer's notes, and temperature records. Shifting-control method used 

October 1-7 and May 21 to June 23. Records good.

DIVERSIONS FEOM SNAKE EIVEE BETWEEN HEISE AND SHELLEY GAGING STATIONS, IDAHO

Between the Heise and Shelley gaging stations 47 separate canals divert water 

from Snake River for irrigation. More than one-third of these head in the Great 

Feeder, an old channel of the river, which has been equipped with head gates. 

Records of discharge of these canals are available from June 1, 1919, to September 

30, 1926.

Stage-discharge relation on many of the canals is affected by growth of aquatic 

plants or by operation of check gates. Rating curves well defined. Gages read 

daily to hundredths. Records good.

SNAKE RIVER 21

DIVERSIONS FROM SNAKE RIVER BETWEEN SHELLEY AND BLACKFOOT BRIDGE GAGING

STATIONS, IDAHO

Fourteen separate canals divert water from Snake River for irrigation between 

Shelley and Lower Blackfoot Bridge gaging stations. Gaging stations are maintained at heading of each canal by the United States Geological Survey for the 

Idaho State Department of Reclamation to facilitate distribution of the water. 

Records are available from May 19, 1924, to September 30, 1926.

Stage-discharge relation on many of the canals is affected by growth of aquatic 

plants or by operation of check gates. Rating curves are well defined. Gages 

read daily May 15 to September 30, and occasional-readings made May 1-14. 

Records good.

between Shelley and Blackfoot Bridge gaging stations, for the year ending September

SNAKE RIVER (NOS. 1 AND 2 CHANNELS) BELOW BLACKFOOT BRIDGE, NEAR BLACKFOOT,

IDAHO

LOCATION. In NW. % sec. 5, T. 3 S., R. 35 E., half a mile below Blackfoot lower

highway bridge and 2 miles west of Blackfoot, Bingham County. 

DRAINAGE AREA. Not measured. 

RECORDS AVAILABLE. April 24, 1924, to September 30, 1926.
22 SURFACE WATER SUPPLY, 1926, PART XII B

GAGE. Friez water-stage recorder on left bank of No. 2 channel one-fourth 

mile below head of island where No. 1 channel separates from main river ^ 

inspected by D. G. Taylor.

DISCHARGE MEASUREMENTS. Made from cables (No. 1 channel, one-fourth 

mile above gage; No. 2 channel, 50 feet below gage) or by wading.

CHANNEL AND CONTBOL. Bed composed of cobbles in gravel drift. Control 

subject to occasional shifts. Banks are low and subject to overflow at 

high stages. Two channels at gage except at low stages, when No. 1 

channel is dry.

EXTREMES OF DISCHARGE. Maximum stage recorded during period, 5.26 feet 

at 4 p. m. May 26 (discharge, 8,490 second-feet); dry on several days in 

September.

1924-1926: Maximum stage recorded, 7.37 feet at 10 p. m. May 23, 

1925 (discharge, 19,100 second-feet); dry on numerous days in summers of 

1925 and 1926.

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

DIVERSIONS. Practically entire summer flow of river above station is appropriated by numerous diversions in the Idaho Falls district. One small 

canal diverts between this station and station at Clough ranch.

REGULATION. Natural flow during irrigation season is augmented by the 

release of stored flood waters in Jackson Lake for use on the Minidoka and 

Twin Falls tracts.

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

defined. Operation of water-stage recorder satisfactory except May 16-21 

and September 11-30, when stage was below intake. Daily discharge 

ascertained April 26 to July 17 by applying to rating table mean daily gage 

height determined from recorder graph by inspection, and for rest of year 

by shifting-control method, except as noted in footnote to table of daily discharge. Records good.

At this point Snake River is divided into three channels, which are listed from 

east to west as Nos. 1, 2, and 3. One gage serves for Nos. 1 and 2 channels and 

another gage for No. 3 channel.

SNAKE RIVfcR (NO. 3 CHANNEL) BELOW BLACEFOOT BRIDGE, NEAR BLACKFOOT, IDAHO

LOCATION. In NW. % sec. 7, T. 3 S., R. 35 E., 2 miles below Blackfoot lower

highway bridge and 3J4 miles southwest of Blackfoot, Bingham County. 

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 3, 1924, to September 30, 1926. 

GAGE. Friez recorder on right bank; inspected by D. G. Taylor. 

DISCHARGE MEASUREMENTS. Made from cable 40 feet below gage or by wading. 

CHANNEL AND CONTROL. Bed composed of coarse gravel over cobbles. Banks

not subject to overflow except at extremely high stages. One channel at

gage, several overflow channels cross island between Nos. 2 and 3 channels at

high stages. 

EXTREMES OF DISCHARGE. Maximum stage recorded during period, 4.09 feet

at 4 p. m. May 26 (discharge, 1,770 second-feet); dry on several days during

September.

1924-1926: Maximum stage recorded, 6.01 feet at 10 p. m. May 23, 1925

(discharge, 4,940 second-feet); channel dry several days during August and

September, 1924, and September, 1925. 

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

discontinued during winter. 

DIVERSIONS. Practically entire natural summer flow of river above station is

appropriated by numerous diversions in the Idaho Falls district. One small

canal diverts between this station and station at Clough ranch.
24 SURFACE WATER SUPPLY, 1926, PART XII B

REGULATION. Normal flow during irrigation season is augmented by the release 

of stored flood waters in Jackson Lake for use on the Minidoka and Twin 

Falls tracts.

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

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

ascertained by shifting-control method. Records good.

At this point Snake River is divided into three channels, which are listed from, 

east to west as Nos. 1, 2, and 3. One gage serves for Nos. 1 and 2 channels and 

another gage for No. 3 channel.

DIVERSIONS FROM SNAKE RIVER BETWEEN BLACKFOOT BRIDGE AND CLOUGH RANCH GAGING

STATIONS, IDAHO

Between Blackfoot Bridge and Clough ranch gaging stations, one small canal1 

(Smith-Maxwell Canal) diverts water from Snake River for irrigation. A gaging 

station is maintained at heading of canal by the United States Geological Survey 

for the Idaho State Department of Reclamation to facilitate distribution of thewater. Records are available May 1, 1924, to September 30, 1926.

Stage-discharge relation affected by growth of aquatic plants. Rating curvefairly well defined. Gage read to hundredths May 8 to September 30. Records, 

fair.

SNAKE RIVER AT CIO UGH RANCH, NEAR BLACKFOOT, IDAHO

LOCATION. In sec. 31, T. 3 S., R. 34 E., a quarter of a mile below mouth of 

Blackfoot River and 14 miles southwest of Blackfoot, Bingham County. 

Blackfoot River is only large tributary between station and mouth of 

Henrys Fork, 60 miles above. Portneuf and Bannock Rivers and about 

2,500 second-feet of spring water enter between this station and station at 

Neeley.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. June 6, 1910, to September 30, 1926.

GAGE. Friez water-stage recorder on right bank; observer, J. A. Clough.

DISCHARGE MEASUREMENTS. Made from cable 50 feet above gage or by wading.

CHANNEL AND CONTROL. Bed composed of very coarse gravel. Two channels 

at low and medium stages. Control shifts slightly during high water.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 7.81 feet at 

8 to 10 a. m. April 23 (discharge, 12,800 second-feet); minimum stage, 1.52 

feet 5 to 8 p. m. September 16 (discharge, 147 second-feet).

1910-1926: Maximum stage recorded, 14.8 feet (approximately) at 5 

p. m. June 18, 1918 (discharge, about 46,200 second-feet); exact discharge 

uncertain because of probable shift in stage-discharge relation at this time. 

Minimum discharge, 118 second-feet at 6 p. m. August 25, 1919.

ICE. Floating ice sometimes present for short periods. Stage-discharge relation 

apparently not affected.

DIVERSIONS. Practically entire natural summer flow of river is diverted above 

station.

REGULATION. Flow regulated by storage in Jackson Lake Reservoir and in 

Blackfoot-Marsh Reservoir on Blackfoot River. Practically entire summer 

flow is released water from these reservoirs.

ACCURACY. Stage-discharge relation not permanent. Two well-defined curves 

used, one from October 1 to January 4 and the other from January 5 to 

September 30. Operation .of water-stage recorder satisfactory. Daily 

discharge obtained by applying mean daily gage height to rating table 

October 1 to May 4 and by shifting-control method from May 5 to September 

30. Records good.

SNAKE RIVER 29

SNAKE RIVER AT NEELEY, IDAHO

LOCATION. In sec, 11, T. 8 S., R. 30 E., half a mile north of Neeley post office, 

Power County, 4 miles southwest of American Falls, and 32 miles above 

Minidoka Dam. Portneuf River, Bannock Creek, and 2,500 second-feet of 

spring water enter Snake River between this station and station at Clough 

ranch. Raft River enters 18 miles below Neeley.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. March 17, 1906, to September 30, 1926",

GAGE. Friez water-stage recorder on left bank; inspected by A. J. Ayres",

DISCHARGE MEASUREMENTS. Made from cable at gage.

CHANNEL AND CONTROL. Bed at measuring section rough; particularly so near 

right bank. Banks high. One channel at all stages. Control composed of 

lava rock probably partly overlain with coarse gravel; shifts slightly.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 6.85 feet at 

8 a. m. April 21 (discharge, 11,600 second-feet); minimum stage, 3.81 feet 

at 6.30 p. m. September 17 (discharge, 2,440 second-feet).

1906-1926: Actual maximum stage doubtful; maximum mean daily stage, 

13.5 feet June 20, 1918 (discharge, 48,400 second-feet); minimum stage, 

about 2.97 feet from 11 a. m. to 4 p. m. October 7, 1924 (discharge about 

1,040 second-feet).

ICE. Stage-discharge relation affected by ice.

DIVERSIONS. Numerous canals near Blackfoot and Idaho Falls divert practically 

entire natural summer flow of Snake River. American Falls Reservoir, now 

nearing completion, will provide storage for future excess summer flow.

REGULATION. Summer flow augmented by stored water from Jackson Lake for 

use on Minidoka and Twin Falls tracts. Low stages due to operation of 

power plant 4 miles upstream. '

ACCURACY. Stage-discharge relation fairly permanent; affected by ice January 

11-15, 17-21, and January 24 to February 3. Curve fairly well defined. 

Operation of water-stage recorder satisfactory except for periods during 

winter when well was frozen. Daily discharge ascertained by applying mean 

daily gage height to rating table except as noted in footnote to table of daily 

discharge. Records good except for period affected by ice in January.

Dam (storage capacity about 67,000 acre-feet above spillway).

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

defined for low and medium stages. Operation of water-stage recorder 

satisfactory. Daily discharge ascertained October 1 to July 30 by applying 

mean daily gage height to rating table, and July 31 to September 30 by 

shifting-control method. Records good.

34 SURFACE WATER SUPPLY, 1926, PART XII B

SNAKE RIVER AT MHNER, IDAHO

LOCATION. In sec. 29, T. 10 S., R. 21 E., 500 yards below Milner Dam, at

Milner, Twin Falls County. No tributaries enter Snake River between

Minidoka station and Milnsr, and no noteworthy inflow between Milner

and station near Twin Falls except seepage and spring water. 

DKAINAGB AREA. Not measured.

RECORDS AVAILABLE. May 10, 1909, to September 30, 1926. 

GAGE. Friez resorder on left bank below highway bridge; inspected by W. N.

McConnel. 

DISCHARGE MEASUREMENTS. Made from a cable 400 yards above gage, from foot

planks midway between gage and cable, or by wading. 

CHANNEL AND CONTRO-L. Bed composed of lava rock, overlain with very slight

gravel deposits and occasional loose rock. Li-ft bank high and steep; right

bank confines flow in narrow gorge below 15-foot stage; full river width above

that point. Control practically permanent. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 11.58 feet at

9 a. m. November 2 (discharge, 7,400 second-feet); minimum stage, 1.43 feet at

5.30 p. m. September 7 (discharge, 10 second-feet).

1909-1926: Maximum stage recorded, 20.1 feet (original gage) June 12,

1909 (discharge, 44,400 second-feet); minimum discharge, 8 second-feet

August 22-26, 1924 (gage height, 1.50 feet). 

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

DIVERSIONS. Twin Falls Canals divert water at Milner Dam just above station,

and two pumping plants, P. A. Lateral, and Milner Low Lift Canal divert

from backwater of Milner Dam. During part of season practically entire

flow of river is taken by these canals. 

REGULATION. Flow past station during irrigation season is regulated at Milner

Dam. 

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

defined. Operation of water-stage recorder satisfactory, except during

extremely low stages, when staff gage was read to hundredths twice daily.

Discharge ascertained by applying mean daily gage height to rating table

October 1 to April 21, arid by shifting-control method April 22 to September

30. Records good. 

COOPERATION. Gage-height record and seven discharge measurements furnished

by Twin Falls Canal Co.

DIVERSIONS. No large diversions between this and the station at Milner. 

Practically entire flow of river is diverted at Milner during part of irrigation 

season by the Twin Falls Canals, and flow at Owsley Bridge is maintained 

largely by springs and waste water from irrigation upstream.

REGULATION. Flow directly regulated by diversions of the Twin Falls Canals 

at Milner.

ACCURACY. Stage-discharge relation changed slightly October 1 and March 1 

Two curves parallel to well-defined rating curve used, one October 1 to February 28 and the other March 1 to September 30. Operation of water-stage 

recorder satisfactory except as noted in footnote to table of daily discharge. 

Daily discharge ascertained by applying to rating table mean daily gage 

height determined from recorder graph by inspection, except as indicated in 

footnote to table of daily discharge. Records good.

SNAKE RIVER AT KING HUL, IDAHO

LOCATION. In sec. 7, T. 5 S., R. 11 E., 300 feet east of Oregon Short Line Railroad

station at King Hill, Elmore County. Big Wood River enters from north

20 miles above station. 

DRAINAGE AREA. -Not measured.

RECORDS AVAILABLE. May 13, 1909, to September 30, 1926. 

GAGE. Inclined staff on right bank; read by employee of United States Bureau

of Reclamation and H. C. Crouch.

DISCHARGE MEASUREMENTS. Made from cable 100 feet below gage. 

CHANNEL AND CONTROL. Bed at gage and measuring section composed largely

of gravel. Control is lava reef partly overlain with gravel; shifts slightly.
SNAKE BIVEB 41

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 8.55 feet 

at 8 a. m. November 10 (discharge, 15,300 second-feet); minimum stage, 5.01 

feet at 7.05 a. m. June 3 (discharge, 5,460 second-feet). A lower minimum may 

have occurred May 27 to June 2 when observer's readings were estimated 

because of deposit on lower end of gage.

1909-1926: Maximum stage recorded, 16.3 feet June 22, 1918 (discharge, 

47,200 second-feet); minimum stage, 4.5 feet July 7-9 and August 15-16, 

1910 (discharge, 4,760 second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. No important diversions between this station and the one at 

Milner.

REGULATION. Flow regulated by diversions at Milner. During certain parts of 

irrigation season, practically entire flow of river is diverted and flow at King 

Hill is derived largely from springs and seepage water from the Twin Falls 

tracts.

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

Gage read to hundredths once daily. Daily discharge ascertained by applying daily gage height to rating table except as indicated in footnote to dailydischarge table. Records good.

COOPERATION. Gage-height record, October to December, furnished by United 

States Bureau of Reclamation.

SNAKE RIVER NEAR MURPHY, IDAHO

LOCATION. In NW. y\ sec. 18, T. 2 S., R. 1 E., Ada County, three-quarters of a 

mile below Swan Falls power plant, 9 miles east of Murphy, Owyhee 

County, and 38 miles below mouth of Bruneau River.

DRAINAGE AREA. 41,900 square miles (measured on United States Land Office 

maps).

RECORDS AVAILABLE.-: August 29 to October 31, 1912; August 21, 1913, to 

September 30, 1926

GAGE. Au water-stage recorder on right bank a quarter of a mile below house 

on Glass ranch; inspected by J. G. Glass.

DISCHARGE MEASUREMENTS. Made from boat at ferry cable 1)4 miles above gage.

CHANNEL AND CONTROL. Bed composed of lava rock overlain with deposits of 

sand, silt, and gravel, where not scoured out by current. Control permanent. 

Banks not subject to overflow.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 5.46 feet at 6 a. m. November 9 (discharge, 16,500 secondfeet) ; minimum mean daily discharge, 6,380 second-feet June 20, July 2, and 

August 15.

1912-1926: Maximum stage recorded, 13.95 feet at 10 p. m. June 22, 

1918 (discharge, 47,300 second-feet); minimum stage, about 2.25 feet at 

6 a. m. August 6, 1917 (discharge, about 5,000 second-feet). Stage probably 

fell equally low at times of minimum load at power plant during low-water 

periods 1919 to 1926.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. A number of small pumping plants divert water for irrigation 

between this and the station at King Hill.

REGULATION. Large diurnal fluctuations in stage are caused by operation of 

gates at dam and by variation in load at power plant, but because of small 

relative amount of storage obtained, the changes are of short duration.

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

Operation of water-stage recorder satisfactory except July 11-15. Daily 

discharge ascertained by applying to rating table mean daily gage height 

obtained by inspection of recorder graph except as indicated in footnote to 

table of daily discharge. Records good.

The following discharge measurements were made:

October 9, 1925: Gage height, 4.38 feet; discharge, 13,900 second-feet.

July 16, 1926: Gage height, 0.28 foot; discharge, 7,430 second-feet.

SNAKE RIVER AT WEISER, IDAHO

LOCATION. In sec. 31, T. 11 N., R. 5 W., a third of a mile above wagon bridge 

at Weiser, Washington County. Between this station and station near 

Murphy, Sucker Creek and Owyhee and Malheur Rivers enter Snake River 

from left, and Boise, Payette, and Weiser Rivers enter from right. ' * 

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. October 8, 1910, to September 30, 1926. Fragmentary 

gage-height record obtained by United States Weather Bureau since 1895.

GAGE. Inclined staff on right bank; read by J. W. Lapish. Elevation of zero 

of gage is at 2,087.22 feet above sea level.

DISCHARGE MEASUREMENTS. Made from cable 200 yards below bridge.

105524 30 4
44 SURFACE WATER SUPPLY, 1926, PART XII B

CHANNEL AND CONTKOL. Bed composed of rocks and coarse gravel. One channel at all stages. Control fairly permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 7.30 feet 

February 7 (discharge, 34,700 second-feet); minimum stage, 1.61 feet 

August 17 (discharge, 5,980 second-feet).

1910-1926: Maximum stage recorded, 13.60 feet May 23, 1921 (discharge, 

83,100 second-feet); minimum stage, 1.35 feet August 5, 1924 (discharge, 

5,100 second-feet). A stage of 15.7 feet was observed March 3, 1910, on 

old Weather Bureau gaga (discharge, about 100,000 second-feet).

ICE. :Stage-discharge relation occasionally affected by ice during severe winters.

DIVERSIONS. Some water is diverted by pumping between Weiser and station 

near Murphy.

REGULATION. Diurnal fluctuations during periods of low water due to operations at Swan Falls power plant above station.

ACCURACY. Stage-discharge relation changed February 6-10 and March 17-20. 

Three well-defined rating curves used October 1 to February 5, February 

11 to March 16, and March 21 to September 30, respectively. Gage read 

to hundredths once daily. Daily discharge ascertained by applying daily 

gage height to rating table except February 6-10 and March 17-20, when 

shifting-control method was used. Records good.

COOPERATION. Gage-height record furnished by United States Weather Bureau.

DIVERSIONS FROM HENRYS FORK BETWEEN ASHTON AND ST. ANTHONY GAGING STATIONS,

IDAHO

Between Ashton and St. Anthony gaging stations six separate canals divert 

water from Henrys Fork for irrigation. Gaging stations are maintained at 

headings of each canal by the United States Geological Survey for the Idaho 

State Department of Reclamation to facilitate distribution of water. Records, 

are available from June 1, 1919,-to September, 30, 1926.

Stage-discharge relation on most of the canals affected by growth of aquatic 

plants or by operation of check gates. Rating curves well defined. Gages read 

to hundredths once daily except May 1-19 when occasional readings were made. 

Discharge interpolated for these days. Records good.

Daily discharge, in second-feet, of canals diverting from Henrys Fork between. 

Ashton and St. Anthony gaging stations, for the irrigation season of 1926

DIVERSIONS FROM HENRYS FORK BETWEEN ST. ANTHONY AND REXBURG GAGING STATIONS,

IDAHO

Between St. Anthony and Rexburg gaging stations four separate canals divert 

water from Henrys Fork for irrigation. Gaging stations are maintained at heading of each canal by the United States Geological Survey for the Idaho State 

Department of Reclamation to facilitate the distribution of water. Records are 

available from June 1, 1919, to September 30, 1926.

Stage-discharge relation on many of the canals affected by growth of aquatic 

plants. Rating curves well denned. Gages read to hundredths once daily 

except May 1-19, when occasional readings were made. Records good.

DIVERSIONS FROM FAIL RIVER ABOVE GAGING STATION NEAR SQUIRREL, IDAHO

Three separate canals divert water from Fall River for irrigation above gaging 

station near Squirrel. Gaging stations are maintained at the headings of each 

canal by the United States Geological Survey for the Idaho State Department of 

Reclamation to facilitate distribution of water. Records are available from 

June 1, 1919, to September 30, 1926.

Stage-discharge relation of these canals affected by growth of aquatic plants. 

Rating curves fairly well defined. Gages read to hundredths once daily May 15 

to September 30. Records good.

DIVERSIONS FROM FALL RIVER BETWEEN SQUIRREL AND CHESTER GAGING STATIONS, IDAHO

Between Squirrel and Chester gaging stations nine separate canals divert 

water from Fall River for irrigation. Gaging stations are maintained at heading 

of each canal by the United States Geological Survey for the Idaho State Department of Reclamation to facilitate distribution of water. Records are available 

from June 1, 1919, to September 30, 1926.

Stage-discharge relation of many of the canals affected by growth of aquatic 

vegetation or by operation of check gates. Rating curves fairly well defined. 

Gages read to hundredths once daily except May 1-19, when occasional readings 

were made. Records good.

Combined daily discharge, in second-feet, of canals diverting from Fall River between 

Squirrel and Chester gaging slations, for the irrigation season of 1926

DIVERSIONS FROM TETON RIVER BETWEEN GAGING STATION NEAR ST. ANTHONY AND MOUTH

OF RIVER, IDAHO

Between St. Anthony gaging station and mouth of Teton River 14 separate 

canals divert water for irrigation. Gaging stations are maintained at heading of 

each canal by the United States Geological Survey for the Idaho State Department of Reclamation to facilitate distribution of water. Records are available 

from June 1, 1919, to September 30, 1926.

Stage-discharge relation of these canals is affected by growth of aquatic plants. 

Rating curves are fairly well defined. Gages read to hundredths once daily 

except May 1-19, when occasional readings were made. Records good.

south of Idmon, and 19 miles northeast of Dubois, Clark County. Station 

is 26 miles north (upstream) of gage on Camas Creek near Camas.

DEAINAGE AREA. 216 square miles (measured on United States Geological 

Survey map of Mud Lake Basin).

RECORDS AVAILABLE. April 11, 1921, to September 13, 1926.

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

Geological Survey engineers.

DISCHARGE MEASUREMENTS. Made from wagon bridge 2 miles above gage or 

by wading 700 feet above gage.

CHANNEL AND CONTROL. Bed composed of lava boulders and gravel; practically 

permanent. Banks fairly high and brushy; right bank subject to overflow. 

Control well defined.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 4.27 feet at 

6.30 a. m. April 13 (discharge, 760 second-feet); minimum stage, 0.67 foot 

from 8 p. m. August 2 to 2 a. m. August 3 (discharge, 7.8 seeond-feet).

1921-1926: Maximum stage recorded, 5.75 feet May 21, 19*22 (discharge, 

1,550 second-feet); minimum discharge, that of August 2-3, 1926.

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

during winter.

DIVERSIONS. Two stock watering ditches of the Wood Live Stock Co. are the 

principal diversions above station. In addition, a number of small irrigation ditches divert water from tributaries above.

REGULATION: Some water stored in Frazier Reservoir on West Camas Creek, 

which has a capacity of 2,000 to 3,000 acre-feet, and released during lowwater period for use above gaging-station.

ACCURACY. Stage-discharge relation changed during winter. Two rating curves 

used during year; one from October 1-18 is well defined between 25 and 900 

second-feet; the other from April 7 to September 13 is well defined below 

200 second-feet. Operation of water-stage recorder satisfactory. Daily 

discharge ascertained by applying to rating table mean daily gage height 

determined by inspection of recorder graph except as noted on footnote to 

table of daily discharge. Records excellent except for May, which are 

good; estimated periods, poor.

The record at this station represents a portion of the natural flow of Big Lost 

River and, taken in conjunction with the record for west channel of Big Lost 

River and with the record for east and west channel's of Warm Spring Creek, will 

show the entire flow of Big Lost River at this point. Except for small diversions 

in several irrigation canals past the stations the combined flow of Big Lost 

River and Warm Spring Creek represents practically the entire surface flow 

at this point into Mackay Reservoir located a short distance below. For record 

at station on west channel of river and on east and west channels of Warm Spring 

Creek see pages 82, 90, and'92, respectively. For combined flow of both channels 

of Big Lost River and both channels of Warm Spring Creek see page 85.

BIG LOST RIVER (WEST CHANNEL) ABOVE MACKAY RESERVOIR, NEAR MACKAY, IDAHO

LOCATION. In sec. 5, T. 7 N., R. 23 E., 3 miles above Mackay Dam, above flow 

line of reservoir, and 7% miles above Mackay, Ouster County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 9, 1919, to September 30, 1926.

GAGE. Stevens 8-day water-stage recorder on left bank; installed May 4, 1920; 

inspected by employees of Utah Construction Co.
TRIBUTARY BASINS 83

DISCHARGE MEASUREMENTS. Made from suspension footbridge just above gage 

or by wading.

CHANNEL AND CONTROL. Bed composed chiefly of gravel. Channel winding; 

banks subject to overflow at extremely high stages. Control of gravel, 

fairly well defined but subject to change.

EXTREMES OF DISCHARGE. Maximum mean daily stage recorded during year, 

1.48 feet May 29 (discharge, 91 second-feet); minimum stage, 1.04 feet 

March 14-16, 25-31, April 1-7, 20-30, May 1 and 2 (discharge, 26 secondfeet).

1919-1926: Maximum discharge, estimated 1,200 second-feet from highwater mark on gage during period June 5-16, 1921, when water-stage 

recorder was not operating (gage height, 4.45 feet); minimum stage, 0.84 

foot May 3-6, 1925 (discharge, 13 second-feet).

ICE. Formation of ice negligible on account of spring inflow above.

DIVERSIONS. None between station and reservoir. Several canals divert water 

above the "dry beds" which extend from a point a few miles above station 

to a point about 15 miles above, near Chilly. No surface flow passes the 

"dry beds" except during fairly high stages.

REGULATION. None.

ACCURACY. Stage-discharge relation unchanged during year. Rating curve 

well defined below 200 second-feet and fairly well defined above to 500 secondfeet. Operation of watei>stage recorder satisfactory. Daily discharge 

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

inspection of recorder graph. Records excellent.

COOPERATION. Gage-height record and three discharge measurements furnished 

by water commissioner for Big Lost River.

The record at this station represents a portion of the natural flow of Big Lost 

River and taken in conjunction with record for east channel of Big Lost River 

and with the record for east and west channels of Warm Spring Creek will show 

the entire surface of Big Lost River at this point. Except for small diversions in 

several irrigation canals past the stations the combined flow of Big Lost River 

and Warm Spring Creek represents practically the entire flow at this point into 

Mackay Reservoir located a short distance downstream. For record at station 

on east channel of river and on east and west channels of Warm Spring Creek 

see pages 80, 90, and 92, respectively. For combined flow of both channels of 

Big Lost River and Warm Spring Creek see page 85.

EXTREMES OF CONTENTS. Maximum stage recorded during year 56.10 feet 

April 18 and 19 (contents, 31,270 acre-feet); no available storage August 12 

to September 30.

1919-1926: Maximum stage recorded, 63.62 feet June 26, 1922 (contents, 

40,500 acre-feet); minimum contents, water surface below bottom of outlet 

tunnel August 1 to October 19, 1919, August 5, 17-27, 31, September 1-5, 

12-14, 18, 1920, August 5, 1924, and August 12 to September 30, 1926 

(minimum stage during these periods, 6.6 feet August 24 to September 2, 

1919).

COOPERATION. Gage-height record furnished by Utah Construction Co., 

through water commissioner for Big Lost River.

Stored water from this reservoir is used for irrigation of land near Arco, under 

the Utah Construction Co.'s Carey Act project. About 5,600 acres are under 

cultivation at present, but this area is subject to change from year to year. 

Elevation of bottom of outlet tunnel corresponds to 7.0 feet on gage, at which 

stage the usable storage is zero, although there is about 125 acre-feet of water in 

reservoir, which is not available for use. Elevation of crest of spillway corresponds to 62.0 feet on gage, at which stage capacity of reservoir is 38,400 acre-feet, 

about 2,400 acres of land being submerged.

used; one from October 1 to December 14 is well defined below 150 secondfeet, and the other from March 19 to September 30 is well defined below 100 

second-feet. Operation of water-stage recorder satisfactory. Daily discharge ascertained by applying to rating table mean daily gage height 

obtained by inspection of recorder graph except as indicated in footnote to 

table of daily discharge. Records good except for estimated periods, for 

which they are fair.

LOCATION. In sec. 29, T. 10 S., R. 21 E., at wagon bridge one-eighth mile below 

head gates at Milner, Twin Falls County.

RECORDS AVAILABLE. May 10, 1909, to September 30, 1926.

GAGE. Friez water-stage recorder on left bank; at site and datum of vertical 

staff gage installed in summer of 1912. Inspected by W. N. McConnel.

DISCHARGE MEASUREMENTS. Made from cable 50 feet above gage.

CHANNEL AND CONTROL. Channel at gage blasted out of rock; practically permanent. Occasional slight changes in control are due to deposition of silt 

and operation of gates at Murtaugh Lake 6 miles downstream.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 10.44 feet at 

8 a. m. May 3 (discharge, 3,600 second-feet); minimum stage, 1.60' feet 

November 2 and 3 (discharge, 53 second-feet).

1909-1926: Maximum discharge recorded, 4,600 second-feet August 12, 

1918; canal dry September 20, 1920.

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. None above gage and none of importance for several miles below.

REGULATION. Flow regulated by head gates.
TRIBUTARY BASINS 111

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

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

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

inspection of recorder graph or by shifting-control method except as noted 

in footnote to daily-discharge table. Records good.

 COOPERATION. Gage-height record and 26 discharge measurements furnished 

by Twin Falls Canal Co.

South Side Twin Falls Canal diverts water from south side of Snake River at 

Milner Dam and furnishes water for stock and irrigation on about 210,000 acres

 of land near Twin Falls. The distribution system comprises about 110 miles of 

main canal and 590 miles of laterals.

ROCK CREEK NEAR TWIN FALLS, IDAHO

LOCATION. On south line of sec. 36, T. 9 S., R. 16 E., at "Highwood" bridge, 3 

miles above confluence with Snake River, and 3% miles northwest of Twin 

Falls, Twin Falls County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. March 27, 1922, to September 30, 1926.

GAGE. Friez water-stage recorder on right bank, installed July 31, 1922; inspected by T. T. Rutledge.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Bed composed of lava rock covered with boulders, 

gravel, and silt. One channel at all stages. Banks high; covered with 

brush. Control formed by lava reef covered in part by boulders and brush 

growth; fairly permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 3.10 feet 2 to 6 p. m. October 25 (discharge, 563 second-feet); 

minimum stage, 0.81 foot from 11 p. m. April 1 to 2 a. m. April 2 (discharge, 

90 second-feet).

1922-1926: Maximum stage recorded, 4.70 feet at 5 p. m. January 29, 

1925 (discharge, 939 second-feet); minimum stage, that of April 2, 1926.

ICE. Stage-discharge relation not affected by ice.

Diversions. After spring floods the natural flow is entirely diverted for irrigation 

several miles upstream. Flow past gage derived largely from waste and 

seepage water from the South Side Twin Falls tract.

REGULATION. At times* waste water from South Side Twin Falls Canal which 

crosses Rock Creek about 10 miles above causes appreciable changes in

ACCURACY. Stage-discharge relation changed several times during year. Rating 

curve well defined between 100 and 350 second-feet and extended above. 

Operation of water-stage recorder satisfactory except for short periods. 

Daily discharge from October 1 to February 16 ascertained by applying to 

rating table mean daily gage height determined from inspection of recorder 

graph, and from February 7 to September 30 by shifting-control method, 

except as indicated in footnote to table of daily discharge. Records good 

except those for stages above 400 second-feet, which are fair, and those for 

estimated periods, which are poor.

COOPERATION. Gage-height record furnished by Murtaugh Irrigation District.

SALMON FALLS CREEK NEAE SAN JACINTO, NEV.

LOCATION. In sec. 23, T. 47 N., R. 64 E., in canyon 200 yards below county 

highway bridge, 250 yards below mouth of Shoshone Creek, and 5 miles 

north of San Jacinto, Elko County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. September 17, 1909, to September 30, 1916; October 1, 

1918, to September 30, 1926.

GAGE. Au water-stage recorder on right bank; installed September 25, 1924; 

inspected by employees of Salmon River Canal Co. (Ltd.).

DISCHARGE MEASUREMENTS. Made from cable 20 feet below gage or by wading.

CHANNEL AND CONTROL. Bed composed of gravel. Control shifts slightly. 

Left bank subject to overflow at high stages. Stage of zero flow determined 

June 12, 1926, gage height 1.70 feet ±0.10 foot.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 4.27 feet at 2 to 3 a. m. March 17 (discharge, 350 secondfeet); minimum discharge, 18 second-feet July 27 and 28.

1909-1916, 1919-1926: Maximum stage recorded, 7.5 feet May 22, 1912 

(discharge, 1,280 second-feet); minimum stage, 2.28 feet July 25, 1919 

(discharge, 10 second-feet).

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

116 SURFACE WATER SUPPLY, 1926, PART XII B 

BIG WOOD EIVEE AT HAILEY, IDAHO

LOCATION. In sec. 9, T. 2 N., R. 18 E., at steel highway bridge a quarter of a 

mile southwest of Hailey, Blaine County.

DRAINAGE AREA. 640 square miles (measured on topographic maps).

RECORDS AVAILABLE. June 11, 1915, to September 30, 1926.

GAGE. Vertical staff in two sections on right bank, installed October 2, 1922; 

read by R. F. Bowman and C. J. Bradley.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Bed composed of coarse gravel and sand; clean. 

Banks low; covered with light brush. Log cribbing along left bank constructed in April, 1922, prevents overflow and confines flood discharge in 

one channel. Control subject to change at high stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 3.60 feet at 

8 a. m. April 30 (discharge, 945 second-feet); minimum stage, 0.46 foot at 5.30 

p. m. August 26 (discharge, 4.8 second-feet). A lower discharge may have 

occurred during estimated periods.

1915-1926: Maximum stage recorded, 5.70 feet June 12, 1921 (discharge, 

3,560 second-feet); minimum discharge, 0.1 second-foot September 10-20 

and October 2-9, 1924.

ICE. Stage-discharge relation slightly affected by ice.

DIVERSIONS. A number of small diversions for irrigation, principally from 

tributaries, are made above station. Hailey power plant, half a mile 

upstream, utilizes as a tailrace a natural channel on east side of river known 

as Big Wood Slough- A large amount of water is diverted from main 

stream in this manner and is returned to river below station. A record of 

the flow of Big Wood Slough is being obtained (see p. 129), and the total 

flow of Big Wood River is represented by amount of water passing both 

stations.

REGULATION. Variation in the amount of water used at Hailey power plant 

causes some diurnal fluctuation at gage, but as observations on the river 

and on Big Wood Slough are practically simultaneous each day, the effect 

of such regulation is probably eliminated.

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

ice December 18 to February 1. Two rating curves used; the first, applicable October 1 to December 18, is well defined below 2,000 second-feet; 

the second, applicable 'February 2 to September 30, is well defined below 

800 second-feet. Gage read twice daily to hundredths April 28 to September 25 and once daily at other times except during winter. Daily discharge 

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

except as indicated in footnote to table of daily discharge. Records good 

except for estimated periods, for which they are poor.

COOPERATION. Five discharge measurements furnished by water master for 

Big Wood and Little Wood Rivers.

Tables of combined discharge of Big Wood River and Big Wood Slough are 

published herein.

4, 1909, gage-height record only is available. Practically no storage prior 

to July 14, 1909, when first stop logs were placed in tunnel entrance.

GAGE. All readings made by measuring with a weighted steel tape from tower 

on east side of dam. Below elevation 4,855 feet readings obtained by measuring from a well-defined offset in walls of tower; whea stages are above that 

elevation measurements are made in a 5%-inch well casing which serves as a 

stilling well, bolted to face of tower. Readings made by attendant at the 

dam. Observations are referred to an assumed datum which is about 137 

feet lower than sea level. (To change readings to sea-level datum about 

137 feet should be subtracted.)

EXTREMES OP CONTENTS. Maximum stage recorded during year, 4,920.33 feet 

April 29 (contents, 140,500 acre-feet); minimum stage recorded, 4,841.91 

feet September 4 (contents, 4,445 acre-feet).

1909-1926: Maximum stage recorded, 4,935.08 feet June 18, 1922 (contents, 191,818 acre-feet); reservoir drained December 24-26 and 29, 1909,

1924.

COOPERATION. Gage-height record furnished by water master for Big Wood 

and Little Wood Rivers.

Stored water from this reservoir is used for irrigation on about 69,000 acres of 

land, under Carey Act project of the Big Wood Canal Co. (Ltd.). Elevation of 

bottom of outlet gates corresponds to 4,818.5 feet on gage, which is about 3 feet 

lower than the actual stage of zero storage. Elevation of concrete lip spillway 

crest corresponds to 4,930 feet on gage. Use of a system of flashboards extends 

the actual elevation of spillway crest to 4,935 feet, at which stage the capacity of 

reservoir is about 191,000 acre-feet, about 4,000 acres being submerged at this 

stage.

Dam and 18 miles northwest of Richfield, Lincoln County. No tributaries 

between dam and station.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 19, 1911, to September 30, 1926.

GAGE. Gurley water-stage recorder on right bank, installed April 20, 1916, 

inspected by Ed Dayton.

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

CHANNEL AND CONTROL. Bed and control composed of clean coarse gravel 

and small boulders; somewhat shifting. Banks high and brushy.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 4.97 feet from 9 p. m. to midnight June 30 (discharge, 1,420 

second-feet); minimum stage, 1.61 feet from 8 p. m. September 27, to 7 a. m., 

September 28 (discharge, 15 second-feet).

1911-1916: Maximum stage recorded, 9.2 feet, May 18, 1911 (discharge, 

5,070 second-feet); no flow reported February 3, 1915.

ICE. Stage-discharge relation seldom affected by ice.

DIVERSIONS. No diversions are made by Big Wood Canal Co. above this station, 

but numerous ranch diversions are made in the upper part of basin, the

ACCTTBACY. Stage-discharge relation changed several times during year. Rating 

curve used prior to November 20 well defined between 20 and 2,500 secondfeet; curve used November 20 to September 30 well defined between 20 and 

1,600 second-feet. Operation of water-stage recorder satisfactory except 

during winter when staff gage was read to hundredths once a week. Daily 

discharge ascertained by applying daily or mean daily gage height to rating 

table or by averaging discharges for intervals of a day, except as indicated 

in footnote to table of daily discharge. Shifting-control method used May 

13 to June 27 and August 25 to September 30. During periods water-stage 

recorder was operated mean daily gage height was determined by inspection 

of recorder graph. Records good except during winter, for which they are 

fair.

COOPERATION. Gage-height record and several discharge measurements furnished by water master for Big Wood and Little Wood Rivers.

BIG WOOD SLOUGH AT HAILEY, IDAHO

LOCATION. In sec. 9, T. 2 N., R. 18 E., at highway bridge, one-eighth mile 

northeast of steel highway bridge across Big Wood River, and one-eighth 

mile southwest of Hailey, Blaine County.

RECORDS AVAILABLE. June 11, 1915, to September 30, 1916.

GAGE. Vertical staff in concrete stilling well on left bank 3 feet below highway 

bridge; installed August 3, 1923; read by R. F. Bowman.

DISCHARGE MEASUREMENTS. Made from footbridge or by wading.

CHANNEL AND CONTROL. Bed composed of sand and gravel. Banks covered with 

brush and may be overflowed. One channel at all stages. Control formed by 

a woodstave water pipe, laid in bed of stream about 15 feet below gage; 

changes slightly.

EXTREMES OF DISCHARGE. Maximum stage recorded during year,. 1.88 feet at. 

5 p. m. November 9 (discharge, 251 second-feet); minimum discharge, 12 

second-feet June 23, 24, and 27.

1915-1926: Maximum stage recorded, 3.00 feet June 6, 1921 (discharge, 

419 second-feet); minimum discharge, 0.9 second-foot March 21-24, 1919:

ICE. Stage-discharge relation seldom affected by ice. > !

DIVERSIONS. None.

REGULATION. The amount of water passing gage is affected by load at power 

plant half a mile upstream, and there is considerable fluctuationj. The main 

river station is affected inversely by any such regulation, so that the accuracy of the summation of the two records is presumably Effected only 

slightly by this factor.

ACCURACY. Stage-discharge relation changed frequently during year by accumulation on and removal of drift from control. Rating curve fairly welldefined. Gage read to hundredths once daily except April 27 to September 25 

during which it was read twice daily. Daily discharge ascertained by shiftingcontrol method. Records from April to September, good; others fair.

COOPERATION. Four discharge measurements furnished by water master for 

Big Wood and Little Wood Rivers.

Big Wood Slough is a natural channel of Big Wood River that is utilized also 

as a tailrace for the Hailey power plant. The record from this station represents 

a portion of the natural flow of Big Wood River and taken in conjunction with the 

record at the near-by station on the main river, will show the entire flow of the 

river at this point. For record from station on the main river see page 116. For 

record of combined flow of Big Wood River and Big Wood Slough see page 118. .

ACCURACY. Stage-discharge relation changed April 18-30, May 26-29, August

16-28, and September 17-30, owing to aquatic growth and brush along

banks. Four curves parallel to well-defined rating curve used during

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

ascertained by shifting-control method, except as noted in footnote to table

of daily discharge. Records good. 

COOPERATION. Gage-height record and some discharge measurements furnished

by water master for Big Wood and Little Wood Rivers.

LITTLE WOOD RIVER AT SHOSHONE, IDAHO

LOCATION. In sec. 2, T. 6 S., R. 17 E., just above diversion dam for town 

water supply and 400 feet above highway bridge on Shoshone-Richfield 

road in Shoshone, Lincoln County. t

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 1, 1922, to September 30, 1926.

GAGE. Gurley water-stage recorder on left bank; inspected by B. E. Powell 

and James Devaney.

DISCHARGE MEASUREMENTS. Made from cable quarter of a mile above gage or 

by wading.

CHANNEL AND CONTROL. Bed composed of lava rock partly overlain with sand 

and gravel. Banks steep. One channel at all stages. Control for low 

and medium stages formed by crest of concrete diversion dam, middle 

section of which consists of flashboards. No well-defined control for high 

stages.

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

recorder, 1.57 feet at 11 p. m. May 26 (discharge, 326 second-feet); minimum stage unknown as water fell below trenched inlet to well several 

times.

1922-1926: Maximum stage recorded, 2.26 feet June 18, 1922 (discharge, 

664 second-feet); minimum stage, 0.34 foot at 10 a. m. September 3, 1924 

(discharge, 0.4 second-foot). 

CE. No record.
TRIBUTARY HASINS 139

DIVEBSIONS. Numerous irrigation diversions above and below. A small ditch 

for the Shoshone water supply diverts from left bank directly below gage.

REGULATION. None except that due to diversions.

ACCURACY. Stage-discharge relation unchanged during year. Rating curve 

used well defined between 0 and 500 second-feet. Operation of waterstage recorder not wholly satisfactory. Owing to stage dropping below 

inlet to well one daily staff reading to hundredths used July 15-18, 25-31, 

August 1, 2, 12-14, 31, arid September 14. Daily discharge ascertained 

by applying to rating table daily or mean daily gage height except as indicated in footnote to table of daily discharge. During periods water-stage 

recorder was operated mean daily gage height determined by inspection 

of recorder graph. Records good. «

COOPERATION. Gage-height record and three discharge measurements furnished 

by water master for Big Wood and Little Wood Rivers.

142 SUEFACE WATER SUPPLY, 1926, PART XII B 

FISH CREEK NEAR CARET, IDAHO

LOCATION. In sec. 22, T. 1 N., R. 22 E., \% miles below dam of Carey ValleyReservoir Co. and 11 miles northeast of Carey, Blaine County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 10, 1919, to September 30, 1920; May 12, 1923, to 

September 30, 1926. Several discharge measurements obtained in" 1921 

and 1922.

GAGE. Vertical staff on left bank, attached to concrete float well, October 1 to 

December 11; Stevens 8-day water-stage recorder on left bank thereafter; 

inspected by A. Gilliam.

DISCHARGE MEASUREMENTS. Made by wading.

CHANNEL AND CONTROL. Bed composed of lava rock covered by gravel, sand, 

and silt. One channel at all stages. Control formed by Cippoletti weir set 

in concrete, located immediately below gage; weir crest is 17.64 feet in 

length. Zero of gage at mean elevation of weir crest.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 1.20 feet from 

midnight to 7.30 a. m. July 17 (discharge, 78 second-feet); practically dry 

during nonirrigation season.

1919-1920, 1923-1926: Maximum stage recorded, 1.46 feet August 3 and 

5, 1923 (discharge, 108 secorid-feet); practically no flow during nonirrigation seasons since completion of reservoir above gage in 1920.

ICE. Stage-discharge relation probably affected by ice; practically no flow in 

winter. *

DIVERSIONS. None between station and dam.

REGULATION. Flow completely regulated by operation of gates in dam above.

ACCURACY. Stage-discharge relation changed slightly. Two rating curves used 

during year; one from October 1 to December 11 is well defined between 0 

and 80 second-feet above which it is extended on basis of standard weir 

formula; the other, based on formula for trapezoidal weirs, used April 29 to 

September 30. Staff gage read once daily to hundredths October 1 to December 11. Operation of water-stage recorder satisfactory April 29 to September 30. Daily discharge determined by applying to rating table daily 

gage height or mean daily gage height obtained by inspection of recorder 

graph; shifting-control method used September 20-30. Records good except for estimated periods, for which they are fair.

COOPERATION. Gage-height record furnished by water master for Fish Creek.

WEST FORE OF FISH CREEK HEAR CARET, IDAHO

LOCATION. In sec. 3, T. 1 N., R. 22 E., 1% miles above confluence with Fish 

Creek, 2 miles above dam of the Carey Valley Reservoir Co., and 14 miles 

northeast of Carey, Blaine County.

DRAINAGE AREA. About 12.5 square miles (measured on base map of Idaho).

RECORDS AVAILABLE. May 11, 1920, to September 30, 1926. Discharge 

measurements only available in 1923.

GAGE. Prior to May 14 measured head of water on weir crest. Staff gage on 

left bank reinstalled May 14, 1926; read by A Gilliam and G. C. Thompson.

DISCHARGE MEASUREMENTS.- Made by wading.

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

at all stages. Control formed by 12-foot'Cippoletti weir set in concrete 

prior to May 14, 1926,-after which it was formed by 4-foot Cippoletti weir 

for stages below 0.26 foot, and by 12-foot weir for higher stages.

EXTREMES OP 'DISCHARGE. Maximum discharge during year, estimated 5.0 

second-feet April 16-28; minimum discharge, estimated 0.1 second-foot 

December 4-7, January 16-31, and July 27-31. Probably not actual 

extremes.

1920-1922, 1925-1926: Maximum stage recorded, 0.93 foot at 9 p. m. 

April 22, 1922 (discharge, 42.8 second-feet); minimum discharge, 0.1 secondfoot at 8.30 p. m. August 8, 1920, for several days in 1924 after June 26, on 

December 4-7, 1925, January 16-31, and July 27-31, 1926.

ICE. jStage-discharge relation affected by ice.

DIVERSIONS. One small diversion above gage.

REGULATION. None.

ACCURACY. Stage-discharge relation changed May 9-14, when artificial control 

formed by 12-foot weir crest was reduced to 4 feet for low stages; slightly 

affected by accumulation of trash on control September 23-30. Rating 

curves used based on standard weir formula and curves parallel thereto as 

defined by discharge measurements. Depth of water over weir crest 

measured to hundredths for days indicated in footnote to table of daily 

discharge. Daily discharge determined by applying daily gage height to 

rating table except for days of missing records for which it was interpolated 

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

except November to April, for which they are poor.

COOPERATION. Gage-height record furnished by water master for Fish Creek.

Spofford and Geological Survey engineers.

DISCHARGE MEASUREMENTS. Made from footbridge or by wading.

CHANNEL AND CONTROL. Bed composed of sand and small gravel. Left bank 

brushy below gage and may be overflowed at high stages. Control formed 

by well-defined riffle 40 feet below gage; subject to change.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 1.91 feet June 14 (discharge, 65 second-feet); channel practically dry after July 31 and November to March.

1917, 1924-1926:. Maximum stage recorded, 2.73 feet July 15, 1925 

(discharge, 127 second-feet); practically no flow except during irrigation 

seasons.

DIVERSIONS. None between reservoir and gage. A small amount of leakage 

from dam above flows to left of gage and enters the creek channel some 

distance below. During 1926 this flow was included in that passing gage.

REGULATION. Flow regulated by gates at Long Tom Reservoir.

ACCURACY. Stage-discharge relation changed during winter. Two welldefined rating curves used, the first applicable October 1-8 and the second 

April 27 to July 31. Operation of water-stage recorder satisfactory except 

Jtfne 17-29. Daily discharge ascertained by applying to rating table mean 

daily gage height determined by inspection of recorder graph, except as 

indicated in footnote to table of daily discharge. Records good.

OWYHEE RIVER NEAR OWYHEE, OREG.

LOCATION. In sec. 2, T. 21 S., R. 46 E., at county bridge \% miles southwest 

of Owyhee, Malheur County, 3 miles above mouth of river, and 10 miles 

southwest of Nyssa.

DKAINAGE ABE A. About 11,100 square miles. Watershed poorly defined on 

available maps.

RECOKDS AVAILABLE. March 26, 1890, to December .31, 1893; January 1, 1895, 

to October 3, 1896; August 28, 1903, to September 30, 1916; May 17 to October 9, 1920; March 8, 1921, to September 30, 1926.

GAGE. Chain gage on upstream side of highway bridge; read by Walter Pinkston or Violet Pinkston.

DISCHAKGE MEASUKEMENTS. Made from bridge or by wading.

CHANNEL AND CONTKOL. Bed composed of gravel; may shift during high stages.

EXTKEMES OF DISCHAKGE. Maximum stage recorded during year, 7.2 feet in the

morning of February 9 (discharge, 6,220 second-feet); no flow July 5 and 6.

1890-1893, 1895-1896, 1903-1916, 1920-1926: Maximum stage recorded,

12.9 feet March 2, 1910 (discharge, 23,200 second-feet); no flow July 7, X9,

August 14-16, 1924, and July 5-6, 1926.

ICE. Stage-discharge relation affected by ice January 4, 5, and 8-19.

DIVEKSIONS. Owyhee Canal, the principal diversion immediately above station, 

heads about 6 miles above gage. This canal diverts practically entire natural low-water flow of river. (See p. 155.)

REGULATION. Variation in the flow may be caused by manipulation of gates at 

head of Owyhee Canal.

ACCUKACY, Stage-discharge relation permanent. Rating curve fairly well defined. Staff gage read to half-tenths once daily. Daily discharge ascer- 

 tained by applying daily gage height to rating table except as stated in 

footnote to daily-discharge table. Records good.

The following discharge measurements were made: 

March 26, 1926: Gage height, 4.45 feet; discharge, 1,460 second-feet. 

June 24, 1926: Gage height, 1.60 feet; discharge, 4 second-feet.

LOCATION. In sec. 21, T. 3 N., R. 4 E., at highway bridge on Boise-Arrowrock 

road, 'a quarter of a mile above mouth, and 5 miles southwest of Arrowrock, 

Boise County.

DRAINAGE AREA. 426 square miles (measured on topographic maps).

RECORDS AVAILABLE. October 1, 1914, to September 30, 1926 (discharge measurements only prior to December 1, 1915).

GAGE. Vertical staff on right bank, 35 feet above highway bridge; read by 

Oliver Call. Prior to October 10, 1925, used a vertical staff on right bank 

20 feet below present site.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Bed composed of boulders, cobbles, and sand. Stream 

usually carries much sand and silt as a result of placer operations in Boise 

Basin. Control shifts frequently owing to deposition of sand at low stages 

and scouring out at high stages. One channel at all stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 2.58 feet 

May 5 (discharge, 809 second-feet); minimum discharge, 12 second-feet 

August 2-8, 13, 16, and 17.

1915-1926: Maximum stage recorded, 6.3 feet April 11, 1916 (discharge, 

3,140 second-feet); minimum discharge, 7.9 second-feet August 13-15, 17, 

and 18, 1924.

ICE. Stage-discharge relation ordinarily not seriously affected by ice.

DIVERSIONS. No important diversions above station.

REGULATION. None.

ACCURACY. Stage-discharge relation changed several times during year. Two 

well-defined rating curves and curves parallel thereto were used. Gage read 

to hundredths once daily; rough water at high stages makes it difficult to 

read gage with refinement. Daily discharge determined by applying daily 

gage height to rating table November 21 to February 28 and July 3 to September 30, and by shifting-control method for remainder of year. Records 

of daily discharge, fair; records of monthly discharge, good. 

COOPERATION. Several discharge measurements made by employees of United 

States Bureau of Reclamation and water master for Boise River.

TBIBTJTABY BASINS 173

CHANNEL AND CONTROL. Concrete control about 200 feet below gage. There 

is some disintegration of concrete during winter because of poor quality. 

Above a medium stage concrete control is submerged and contraction and 

riffle 200 feet farther downstream acts as control.

.EXTREMES OF DISCHARGE. Maximum stage recorded during year, 4.80 feet 

May 2-3 (discharge, 470 second-feet); seepage amounted to 1 second-foot 

when gates to reservoir were closed October 9 to April 19.

1906-1926: Maximum discharge recorded, 5,490 second-feet March 2, 

1910; minimum discharge recorded prior to construction of dam, practically 

mo flow during August, 1910; determined by subtracting discharge of South 

Fork from discharge of main river below South Fork. Minimum discharge 

since construction of dam somewhat less than 1 second-foot when gates 

are closed; stream was dry August 1 to September 16, 1919, while dam 

was being constructed.

ICE. No water released from dam during winter.

^DIVERSIONS. A large area of bottom land is irrigated with flood water above 

station.

REGULATION. Flow past station entirely controlled by operation of gates in 

Warmsprings Dam beginning November, 1919.

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

Staff gage read to hundredths once daily and time noted when change was 

made in gate openings at dam. Daily discharge ascertained by applying 

idaily gage height or weighted daily gage height to rating table. Records 

good.

permanent prior to December 22, 1924, after which time several changes 

occurred by filling in and washing out of material on control caused by 

highway excavation on side hill above on left bank.
TRIBUTARY BASINS 187

EXTREMES or DISCHARGE. Maximum stage recorded during year, 9.15 feet 

May 5 (discharge, 9,890 second-feet); minimum stage, 1.96 feet September 

15 (discharge, 620 second-feet).

1922-1926: Maximum stage recorded, 12.54 feet June 7 and 8, 1922 

(discharge, 18,900 second-feet); minimum discharge, 455 second-feet December 18, 1924.

ICE. Stage-discharge relation affected by ice.

DIVERSIONS. Several diversions for irrigation from tributaries above station.

REGULATION. Spring and summer flow slightly -affected by regulation at outlet 

of Payette Lake, 58 miles upstream.

ACCURACY. Stage-discharge relation changed slightly at low stages following

maps).

RECORDS AVAILABLE. November 23, 1912, tc September 30, 1916; July 27, 

1919, to September 30, 1926. February 13, 1906, to November 22, 1912, 

at site in sec. 2, 2 miles upstream. Two small creeks enter between the 

two stations.

GAGE. Au water-stage recorder on right bank, installed November 29, 1924; 

inspected by L. W. Goodin.

DISCHARGE MEASUREMENTS. Made from cable 200 feet below gage.

CHANNEL AND CONTROL. Bed of stream composed of cobbles and coarse gravel 

with a few large rocks. Control practically permanent. One channel at 

all stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 6.04 feet at 9 a. m. May 5 (discharge, 9,920 second-feet); 

minimum discharge, 565 second-feet 5 to 7 a. m. September 16.

1906-1916, 1919-1926: Maximum stage recorded, 9.57 feet at 1 p. m. 

June 9, 1921 (discharge, 22,100 second-feet); minimum stage recorded, 

0.30 foot at 10 p. m. December 18, 1924 (discharge, 365 second-feet).

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

DIVERSIONS. Several diversions for irrigation from tributaries above station; 

none between this station and the one at Banks.

REGULATION. During irrigation season, flow past station slightly affected by 

regulation at outlet of Payette Lake 70 miles upstream.

ACCURACY. Stage-discharge relation changed slightly at low stages following 

high water of June 16. Two rating curves used well defined between 600 

and 21,000 second-feet; the first applicable prior to June 16, and the other 

applicable thereafter. Operation of water-stage 'recorder satisfactory. 

Daily discharge ascertained by applying to rating table mean daily gage 

height determined by inspection of recorder graph. Records excellent.

Between the stations at Banks and Horseshoe Bend the river leaves the granite 

and enters the lava, and a loss in flow occurs which ranges from 2 to nearly 4 

per cent of the mean annual flow.

PAYETTE RIVER NEAR .EMMETT, IDAHO

LOCATION. -In sec. 22, T. 7 N., R. 1 W., three-eighths mile below Black Canyon 

Dam and 5 miles northeast of Emmett, Gem County. *

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. June 11, 1925, to September 30, 1926.

GAGE. Au water-stage recorder on right bank, installed June 11, 1925; inspected 

by C. A. Harris.

DISCHARGE MEASUREMENTS. Made from cable 800 feet above gage.

CHANNEL AND CONTROL. Bed composed of rock and coarse gravel. One channel 

at all stages. Control formed by well-defined rock and gravel riffle; may 

shift.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 9.29 feet at 12.10 p. m. May 5 (discharge, 14,400 second-feet); 

minimum stage, 1.17 feet from 3 to 4.30 p. m. March 3 (discharge, 56 secondfeet).

1925-1926: Maximum and minimum stages recorded occurred during 

1926.

TCE. Stage-discharge relation probably affected by ice during severe winters.

DIVERSIONS. Numerous canals divert water for irrigation above and below 

station.

REGULATION. Flow past gage affected at times by operation of gates in Black 

Canyon Dam and by storage of water in Payette Lake.

ACCURACY. Stage-discharge relation probably changed slightly November 18 

and May 5. Three rating curves, well defined between 250 and 6,500 secondfeet, used, respectively, November 19 to May 5, May 6 to September 30, and 

October 1 to November 18. Operation of water-stage recorder satisfactory 

except for short period owing to broken pencil. Daily discharge ascertained 

by applying to rating table mean daily gage height determined by inspection 

of recorder graph. Records excellent below 6,500 second-feet; others good.

COOPERATION. Gage-height record furnished by United States Bureau of 

Reclamation.

192 SURFACE WATER SUPPLY, 1926, PART XII--B

DEADWOOD RIVER NEAR LOWMAN, IDAHO

LOCATION. In sec. 29, T. 9 N., R. 7 E., 600 feet above bridge on Garden ValleyLowman highway, 700 feet above confluence with South Fork of Payette 

River, and 2^ miles west of Lowman, Boise County.

DRAINAGE AREA. 201 square miles (revised; measured on Forest Service maps).

RECORDS AVAILABLE. August 11, 1921, to September 30, 1926.

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

Forest^ Service rangers.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Bed composed of gravel and boulders; rough. Banks 

fairly low but not subject to overflow; gradient steep. Control fairly well 

defined, wide, and not sensitive; practically permanent.

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

recorder, 3.71 feet at 1 a. m. May 5 (discharge, 1,810 second-feet); minimum 

stage recorded, 1.32 feet August 16 (discharge, 86 second-feet). Actual 

minimum discharge probably occurred December 30 or 31 during ice-affected 

period.

1921-1926: Maximum stage recorded, 4,53 feet at 3 a. m. May 26, 1922 

(discharge, 3,080 second-feet); minimum stage recorded, 1.12 feet August 

29, 1924 (discharge, 75 second-feet). Lower discharge may have occurred 

about December 18, 1924, during extreme cold period.

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation changed during ice-affected period December 25 to February 28. Two rating curves used; the first, applicable 

October 1 to December 20, is well defined between 100 and 1,700 second-feet 

and the other, applicable March 7 to September 30, is well defined between 

90 and 1, 700 second-feet. Staff gage read to hundredths about once a week 

during winter, because of severe ice conditions. Operation of water-stage 

recorder satisfactory for remainder of year. Daily discharge ascertained by 

applying to rating table daily staff gage height or mean daily gage height 

determined by inspection of recorder graph except as noted in footnote to 

table of daily discharge. Records .good except those for November to 

February, which are fair.

COOPERATION. Services of observer furnished by United States Forest Service.

'(discharge, 4,250 second-feet); minimum discharge, that of September 30, 

1926.

ICE. Stage-discharge relation very seldom affected by ice, presumably because of 

proximity of station to Payette Lake.

DIVERSIONS. None above station.

REGULATION. Flow during irrigation season partly regulated by changing flashboards in dam installed in October and November, 1923, at outlet of Payette 

Lake.

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

well defined below 2,700 second-feet. Water-stage recorder operated satisfactorily except July 5-26 and August 21 to September 1, when staff gage was 

lead frequently to hundredths. Daily discharge ascertained by applying 

io rating table daily staff gage reading or mean daily gage height determined 

by inspection of recorder graph, except as noted in footnote to table of daily 

discharge. Records above 300 second-feet excellent; others fair.

COOPERATION. Services of observer furnished by United States Forest Service.

gage is at bottom of rating flume.

DISCHARGE MEASUREMENTS. Made from foot walk across concrete rating flume.

CHANNEL AND CONTROL. Canal above and below gage is about 20 feet wide. 

Bed composed of hard clay and gravel; fairly permanent. Banks are clean 

and not subject to appreciable growth of moss or weeds.

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

recorder, 3.43 feet at 9 a. m. May 5 (discharge, 219 second-feet). Canal 

reported practically dry from December to March and April 17 to 18.

1920-1926: Maximum discharge recorded, that of May 5, 1926; canal 

usually dry except during irrigation season.

DIVERSIONS. One farm lateral diverts about a quarter of a mile above gage.

REGULATION. Flow regulated at Luck waste gate, half a mile above, which in 

practice forms the head of the canal, although actual diversion from Weiser 

River is located about 1% miles above gage. Water from waste gate returns 

to Weiser River through slough which formerly was main channel of river.

ACCURACY. Stage-discharge relation not permanent. Three well-defined rating 

curves used; one October 1-26, another April 7 to May 21, and July 27 to 

September 20, and a third May 29 to July 20. Operation of water-stage 

recorder satisfactory except October 18 to 23, when staff gage was read to 

hundredths once daily. Daily discharge ascertained by applying to rating 

table daily staff-gage reading or mean daily gage height obtained by inspection of recorder graph except as indicated in footnote to table of daily discharge. Shifting-control method used May 22-28 and July 21-26. Records 

excellent except those from May to July, which are good.

COOPERATION. Gage-height record furnished by Weiser Irrigation District.

The Weiser Irrigation District Canal diverts water from north side of Weiser 

River in sec. 3, T. 10 N., R. 4 W., \% miles above gage, and furnishes water for 

irrigation of about 7,000 acres, included in projects of the Weiser Irrigation District and Weiser Bench Irrigation District near Weiser. The district maintains 

about 20 miles of main canal.

SALMON RIVER BELOW YANKEE FORK, NEAR CLAYTON, IDAHO

LOCATION. In sec. 20, T. 11 N., R. 15 E., an eighth of a mile below Sunbeam 

Dam and mouth of Yankee Fork, 4 miles above Robinson Bar, 12 miles 

below Stanley and mouth of Valley Creek, and 17 miles above Clayton, 

Ouster County.

DRAINAGE AREA. 841 square miles (measured on topographic maps).

RECORDS AVAILABLE. October 28, 1921, to September 30, 1926.

GAGE. Vertical staff on left bank; read by Llewellyn Clawson.

DISCHARGE MEASUREMENTS. Made from cable three-tenths mile below gage.

CHANNEL AND CONTROL. Bed composed of boulders and gravel. Banks high; 

one channel at all stages. Control formed by well-defined boulder and rock 

riffle; practically permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 3.50 feet at 7.30 

a. m. May 5 (discharge, 2,360 second-feet); minimum stage, 0.07 foot at 

12.50 p. m. September 25 (discharge, 274 second-feet).

1922-1926: Maximum stage recorded, 7.6 feet June 7, 15, and 17, 1922 

(discharge, 6,760 second-feet); minimum stage, that of September 25, 1926.

ICE. Stage-discharge relation affected by ice.

DIVERSIONS. None of importance above station.

REGULATION. None. Future operation of power plant at Sunbeam Dam may 

affect flow somewhat during low stages, owing to probable changes in gage 

opening. Power plant not in operation at present.

ACCURACY. Stage-discharge relation unchanged after March 8. Two rating 

curves well defined between 300 and 6,000 second-feet used from October 11 

to November 3 and March 9 to September 30, respectively. Gage read 

usually to hundredths twice daily April 9 to September 30; once daily at other 

times. Daily discharge ascertained by applying daily gage height or mean 

daily gage height to rating table, except as indicated in footnote to table 

of daily discharge. Records for October and June to Septembei!' good; 

others fair except those for November 4 to March 8, which are poor.

COOPERATION. Gage-height records furnished by Love & von Brecht.

VALLEY CREEK AT STANLEY, IDAHO

LOCATION. In sec. 3, T. 10 N., R. 13 E., one-eighth mile above Valley Creek 

ranger station, one-fourth of a mile above confluence with Salmon River, 

and three-eighths of a mile below Stanley, Ouster County.

DRAINAGE AREA. 176 square miles (measured on topographic maps).

RECORDS AVAILABLE. December 21, 1910, to October 31, 1913; May 2, 1921, 

to September 30, 1926.

GAGE. Vertical staff on left bank, installed May 2, 1921; read by W. L. Rose 

and R. E. Alien.

DISCHARGE MEASUREMENTS. Made from log bridge 300 feet upstream or by 

wading.

CHANNEL AND CONTROL. Bed composed of gravel. Banks fairly low; left bank 

may be overflowed at extremely high stages. Control well defined; practically permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 2.26 feet on 

May 5 (discharge, 507 second-feet); minimum discharge considerably less 

than 55 second-feet occurred during estimated period December 26 to 

January 15.

1910-1913, 1921-1926: Maximum stage recorded, 4.4 feet May 29, 1921 

(discharge, 1,850 second-feet); minimum stage, 0.84 foot September 7, 

1924 (discharge, 41 second-feet).

ICE. Stage-discharge relation affected by ice.

DIVERSIONS. A few ranch diversions for irrigation above station.

REGULATION. None.

ACCURACY. Stage-discharge relation changed slightly during year. Two welldefined rating curves used; the first applicable October 4 to December 9 

and the second applicable March 10 to September 30. Gage read to hundredths twice daily April 10 to June 2, somewhat irregularly at other times. 

Daily discharge determined by applying daily or mean daily gage height to 

rating table except as indicated in footnote to table of daily discharge. 

Records good for October and April to September; others fair except those 

for estimated periods, which are poor.

YANKEE FORK OF SALMON RIVER NEAR CIAYTON, IDAHO

LOCATION. In sec. 20, T. 11 N., R. 15 E., at Sunbeam Dam, 350 feet above 

confluence with Salmon River, 3 miles west of Robinson Bar, 7 miles south 

of Bonanza, and 18 miles west of Clayton, Ouster County.

DRAINAGE AREA. 195 square miles (measured on topographic maps).

RECORDS AVAILABLE. May 3, 1921, to September 30, 1926.

GAGE. Vertical staff on right bank; read by Llewellyn Clawson.

DISCHARGE MEASUREMENTS. Made from highway bridge 175 feet below gage 

or by wading.

CHANNEL AND CONTROL. Bed composed of rock, boulders, and gravel. One 

channel at all stages. Control formed by rock and gravel riffle 50 feet 

below gage; well defined at low and medium stages. Although gradient is 

steep, control is not well defined at high stages owing possibly to a slight 

backwater effect from Salmon River when in flood.

EXTREMES OF DISCHARGE. Maximum discharge, 602 second-feet, occurred 

May 5; minimum discharge, probably less than 30 second-feet, occurred 

during frozen period December 25 to January 15.

1921-1926: Maximum stage recorded, 5.24 feet at 8 p. m. June 12, 1921 

(discharge, 3,360 second-feet); minimum discharge, 22 second-feet, April 5, 

x 1924 (gage height, 0.10 foot). Lower flow may have occurred during iceaffected periods.

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. None.

REGULATION. None.

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

between 30 and 800 second-feet, above which it is extended parallel to former 

curve. Gage read usually to hundredths twice daily April 9 to September 

30; once daily at other times. Daily discharge ascertained by applying 

daily or mean daily gage height to rating table except as indicated in footnote to table of daily discharge. Records fair except for estimated periods, 

for which they are poor.

COOPERATION. Gage-height record furnished by Love & vonBrecht.

BIG BOULDER CREEK NEAR CLAYTON, IDAHO

LOCATION. In NE. % sec. 15, T. 9 N., R. 17 E., below power plant of the Livingston Mines Corporation, half a mile above junction with East Fork of Salmon 

River, and 11 miles southwest of Clayton, Custer County.

DRAINAGE AREA. 27 square miles (measured on topographic map and land 

office map).
TRIBUTARY BASINS 227

RECORDS AVAILABLE. May 15 to September 30, 1926.

GAGE. Vertical staff on left bank; read by power-plant operators.

DISCHARGE MEASUREMENTS. Made by wading.

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

all stages. Control is well-defined riffle immediately below gage; not permanent.

EXTREMES OF DISCHARGE. Maximum .stage .recorded during period of record, 

1.32 feet at 7 a. m. May 20 (discharge, 47 second-feet); minimum measured 

discharge, 5.9 second-feet September 23. Maximum flow of probably more 

than 100 second-feet occurred for short time on August 24 from break in 

surge tank.

DIVERSIONS. Livingston Mines Corporation diverts water for power purposes 

about three-quarters of a mile upstream, but water is returned to stream 

30 feet above gage.

REGULATION. Flow practically unaffected by power diversion above.

ACCURACY. Stage-discharge relation changed on August 24 by gravel deposit on 

control caused by break in power plant surge tank on hillside above gage. 

Two rating curves used; the first applicable prior to August 24 is fairly well 

defined between 15 and 150 second-feet, above and below which it is extended, 

and the second applicable after September 22 is fairly well defined. Gage 

read to hundredths twice daily* except as noted in footnote to table of daily 

discharge. Daily discharge ascertained by applying mean daily gage height 

to rating table. Records fair except those for estimated period, which are 

poor.

minimum stage recorded during year, 1.03 feet August 1, 2, 5, and 6 (discharge, 44 second-feet).

1921-1926: Maximum stage recorded, determined on that day from watermarks on gage house, 5.0 feet shortly prior to June 12, 1925 (discharge, 

from extension of rating curve, about 2,800 second-feet); minimum stage 

recorded, August 1, 2, 5, and 6, 1926. Lower discharge probably occurred 

during period of no record.

ICE. Stage-discharge relation affected by ice; records discontinued during winter.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation fairly permanent. Rating curve, well defined between 60 and 900 second-feet, and curve parallel thereto were used. 

Operation of water-stage recorder satisfactory except during August and

EAST FORK OF WAIIOWA RIVER NEAR JOSEPH, OREG.

LOCATION. In SE. % sec. 29, T. 3 S., R. 45 E., one-fourth mile above mouth, 

1 mile below diversion dam of Wallowa Falls power plant, 1 mile above 

Wallowa Lake, and 6 miles south of Joseph, Wallowa County.

DISCHARGE AREA. Not measured.

RECORDS AVAILABLE. July 27, 1924, to September 30, 1926.

105524 30 16
236 SUEFACE WATER SUPPLY, 1926, PART XII B

GAGE. Vertical staff on right bank, 100 yards above bridge on road to power

house; read by W. K. Wagner. Also auxiliary inclined gage at diversion

dam 1 mile above. 

DISCHARGE MEASUREMENTS. Made from bridge 100 yards below gage, from

plank across stream, or by wading. 

CHANNEL AND CONTROL. Channel curved above and below gage. Bed of

coarse gravel and boulders; practically permanent. Steep gradient. Banks

are not overflowed except in extremely high water. Control 10 feet below

gage; well defined. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 1.44 feet

May 1 (discharge, 36 second-feet); minimum stage, 0.70 foot August 24

and 25 (discharge, 1.8 second-feet).

1924-1926: Maximum stage recorded, 1.92 feet June 29, 1925 (discharge,

111 second-feet); minimum stage, that of August 24-25, 1926. 

ICE. Stage-discharge relation seriously affected by ice. 

DIVERSIONS. The penstock to power house of Wallowa Falls power plant

, diverts at dam 1 mile upstream. 

REGULATION. Operation of power plants affects flow, maximum effect being

during low-water period; during extremely low-water periods in winter

practically all flow at dam is diverted. 

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

Rating curve fairly well defined. Staff gage read to hundredths twice daily

except during winter and August 12 to September 8, when it was read once

daily. Daily discharge ascertained by applying daily or mean daily gage

height to rating table. Records good for open channel and fair during ice

period.

Discharge over dam, length of crest of spillway being 21.6 feet, has been computed from weir tables for rectangular contracted weir, the application of which 

was checked by one discharge measurement, for the few days gage at dam was 

read. These records indicate that inflow between dam and gaging station is 2 to 3 

second-feet at low water and averages 17 per cent of flow at gaging station when 

flow at station is more than 15 second-feet.

CIEARWATER RIVER NEAR IEWISTON, IDAHO

LOCATION. In NE. % sec. 28, T. 36 N., R. 5 W., three-eighths mile below concrete diversion dam under construction by Inland Power & Light Co., 3 

miles east of the Eighteenth Street highway bridge at Lewiston, Nez Perce 

County, and 4 miles above mouth of river.

RECORDS AVAILABLE. August 23, 1910, to October 31, 1913; October 2, 1924, 

to September 30, 1926.

DRAINAGE AREA. 9,640 square miles.

OAGE. Stevens continuous water-stage recorder on right bank at former Central 

Ferry site; reinstalled October 2, 1924; inspected by employees of Inland 

Power & Light Co. Zero of present gage at elevation 733.33 feet above 

mean sea level, United States Geological Survey datum from bench marks 

at Lewiston described in Bulletin 567.

DISCHARGE MEASUREMENTS. Made from highway bridge at Lewiston and 

Spalding, and from cable, 8 miles upstream at Spalding.

CHANNEL AND CONTROL. Bed composed of boulders and gravel. Two channels 

at extremely high stages. Control formed by well-defined gravel and boulder 

riffle; practically permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 13.36 feet from 3 to 4 p. m. April 19 (discharge, 62,400 

second-feet); minimum stage recorded, 2.4 feet August 14 and 16 (discharge, 

2,030 second-feet).

1910-1913, 1924-1926: Maximum stage recorded, 16.0 feet (17.3 feet 

present datum) May 28, 1913 (discharge, 98,800 second-feet); minimum 

stage recorded, that of August 14 and 16, 1926. Actual maximum stage 

and discharge on May 28, 1913, was probably somewhat higher than was 

recorded as indicated by comparison with gage heights obtained at city of 

Lewiston pumping plant.

Crest elevation during flood of June, 1894, was 20.8 feet, present gage 

datum (discharge, about 136,000 second-feet) as determined by J. C. Stevens, 

who referred the high-water mark to the Central Ferry gage during investigations made in 1924.

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

severe winters.

DIVERSIONS. Practically none.

REGULATION. None.
TEIBUTABY BASINS 251

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

between 2,000 and 50,000 second-feet, above which it is extended. Operation of water-stage recorder satisfactory except for short periods. Daily 

discharge ascertained by applying to rating table mean daily gage height 

determined by inspection of recorder graph except as indicated in footnote 

to table of daily discharge. Records good except those for estimated periods, 

which are fair.
