SUEFACE WATER SUPPLY OF SNAKE RIVER

BASIN, 1927

AUTHORIZATION AND SCOPE OF WORK

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

measurements of flow made on streams in the United States during 

the year ending September 30, 1927.

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 dorrain.

The work was begun in 1888 in connection with special studies 

relating to irrigation. Since the fiscal year ending June 30, 1895, 

successive appropriation bills passed by Congress have carried the 

following items:

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

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

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

In this work many private and State organizations have cooperated, either by furnishing records 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 5,330 

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

the Hawaiian Islands. In July, 1927, 1,750 gaging stations were being maintained by the Geological Survey and the cooperating organizations. Many miscellaneous discharge measurements are made at 

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

in regard to precipitation, evaporation, storage reservoirs, river 

profiles, and water power in many sections of the country and will be 

made available in the water-supply papers from time to time.

DEFINITION OF TERMS

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

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

into two groups (1) those that represent a rate of flow, as second-feet, 

gallons per minute, miner's inches, and discharge in second-feet per 

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

as run-off in inches, acre-feet, and millions of cubic feet. The principal terms used in this series of reports are second-feet, second-feet 

per square mile, run-off in inches, and acre-feet. They may be 

defined as follows:

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

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

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

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

unit from which others are computed.

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

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

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

regards time and area.

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

if all the water flowing from it in a given period were uniformly distributed on the surface. It is used for comparing run-off with rainfall, which is usually expressed in depth in inches.

An "acre-foot," equivalent to 43,560 cubic feet, is the quantity required to cover an acre to the depth of 1 foot. The term is1 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 determines the stage-discharge 

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

be the same section or sections at all stages.

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

gage the gage height at which water ceases to flov^ over the

control.

EXPLANATION OF DATA

The data presented in this report cover the year beginning October 1, 1926, and ending September 30, 1927. At the beginning of 

January in most parts of the United States much of the precipita-
EXPLANATION OF DATA O

tion in the preceding three months is stored in the form of snow or 

ice, or in ponds, lakes, and swamps, or as ground water, and this 

stored water passes off in the streams during the spring brer,k-up. 

At the end of September, on the other hand, the only stored water 

available for run-off is possibly a small quantity in the ground; therefore the run-off for the year beginning October 1 is practically all 

derived from precipitation within the year.

The base data collected at gaging stations consist of records of 

stage, measurements of discharge, and general information ueed 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

FIGURE 1. Typical gaging station

that gives a continuous record of the fluctuations. Measurements of 

discharge are made with a current meter by the general methods 

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 

height to these rating tables gives the daily discharge from which 

the monthly and yearly mean discharges are determined.

The data presented for each gaging station in the area covered 

by this report comprise a description of the station, a table showing 

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

discharge and run-off.

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

tables giving daily gage height and results of discharge measurements 

are published.
4 SURFACE WATEE SUPPLY, 1927, PAET 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 fluctuation the discharge obtained from the rating table and mean daily 

gage height may not be the true mean discharge for the day. If 

such stations are equipped with water-stage recorders, the mean daily 

discharge may be obtained by averaging discharge at regular intervals during the day or by use of the discharge integrator, an instrument operating on the principle of the planimeter and containing as 

an essential element the rating curve of the station.

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

gives the mean flow for the day when the mean gage height was highest. As the gage height is the mean for the day, it does not indicate 

correctly the stage when the water surface was at crest height, and 

the corresponding discharge was consequently larger than given in 

the maximum column. Likewise, in the column headed "Minimum," 

the quantity given is the mean flow for the day when the mean gage 

height was lowest. The column headed "Mean" is the average flow 

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

based computations recorded in the remaining columns, which are 

denned on page 2.

ACCURACY OF FIELD DATA AND COMPUTED F,ESULTS

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 the daily gage height to the rating table to obtain the 

daily discharge.

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

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

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

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

individual measurements with reference to the mean rating curve.
PUBLICATIONS O

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 by the Geological Survey in earlier reports si ould 

be used with caution because of possible inherent but unknown 

sources of error.

Many gaging stations on streams in the irrigated sections of the 

United States are located 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 belov^ the 

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

prior appropriations, a paragraph on diversions is presented in each 

station description. The figures given can not be considered exact 

but represent the best information available.

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

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

estimates; the tables of daily discharge allow more detailed studies of 

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

observations in each succeeding year may be expected to throw new 

light on data previously published.

PUBLICATIONS

Investigation of water resources by the United States Geological 

Survey has consisted in large part of measurements of the volume 

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

but it has comprised also investigation of such closely allied subjects 

as irrigation, water storage, water powers, underground waters, and 

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

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

appeared in the bulletins, professional papers, monographs, and 

annual reports.

SNAKE RIVER NEAR EEISE, 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 30, 1927.

EQUIPMENT. Friez water-stage recorder on left bank. Discharge measurements 

made from cable 100 feet above gage. Zero of gage at 5,016.90 feet, sea-level 

datum.

CHANNEL AND CONTBOL. Bed composed of rock ledge, coarfe gravel, and 

cobblestones. One channel at all stages. Control formed by Anderson 

Dam, greater part of which washed out on May 19.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 13.90 feet 

at 10.50 a. m. May 19 during flood caused by the washing out of the landslide 

on Gros Ventre River in Wyoming (discharge not definitely determined but 

believed to have been about 60,000 second-feet); minimum stage recorded, 

1.27 feet at 3 p. m. February 10 (discharge, 2,000 second-feet).

1910-1927: Maximum discharge, that of May 19, 1927; minimum discharge, that of February 10, 1927 (discharge may h ave been less during iceaffected periods).

DIVERSIONS AND REGULATION. One canal with maximum capac'ty of about 30 

second-feet diverts water 1 mile above station and several canals divert from 

tributary streams in Swan Valley section, 30 miles upstream. Flow controlled 

to a large extent at outlet of Jackson Lake Reservoir where water is generally 

stored during winter and released during later part of summer.

ACCURACY. Stage-discharge relation changed January 4-14, May 19, June 3-27; 

seriously affected by ice December to February. Rating curves applicable 

between shifts are well defined between 2,000 and 30,000 second-feet by 18 

discharge measurements obtained during year. Operation of water-stage 

recorder satisfactory except October 3-8 and 24-27, when no records were 

obtained, December 14 to March 28, when daily staff readings were used, 

and at times between May 19 and June 2, when intake to float well was 

partly clogged. Discharge ascertained by applying mean daily gage height 

to rating table; shifting-control method used January 4-14, May 19, and 

June 3-27. Records good except those for periods of shifting control or ice 

effect, which are fair.

DIVERSIONS FROM SNAKE RIVER BETWEEN HEISE AND SHEIIEY GASIFY STATIONS, IDAHO

Between Heise and Shelley gaging stations 50 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 are available from June 1, 1919, to September 30, 1927.

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

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

daily to hundredths except during September, when occasional readings were 

made. Records good.

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

between Heise and Shelley gaging stations, Idaho, for the year ending September

18 SURFACE WATER SUPPLY, 1927, PART XII B

DIVERSIONS FROM SNAKE RIVER BETWEEN SHELLEY AND BLACKFOOT1 BRIDGE GAGING STATIONS, IDAHO

Between Shelley and Blackfoot Bridge gaging stations 14 separate canals 

divert from Snake 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 the water. Records are 

available from May 19, 1924, to September 30, 1927. From June 1, 1919, to September 30, 1923, diversions were summarized in two groups with station at Porterville Bridge for the point of division. After October 1, 1923, the intermediate 

point was at Blackfoot Bridge.

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

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

to hundredths daily except during September when occasional readings were 

made. Records good.

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

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

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

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

and 2 miles west of Blackfoot, Bingham County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 24, 1924, to September 30, 1927.

EQUIPMENT. Friez 8-day water-stage recorder on left bank or No. 2 channel onefourth mile below head of island where No. 1 channel separates from main 

river. Discharge made from cables on each channel or by wading.
SNAKE RIVER 19

CHANNEL AND CONTROL. Bed composed of cobble in gravel drift. Control 

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

stages. Two channels at gage, except at low stages when No. 1 channel is dry.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 8.30 feet from 

6 to 10 p. m. June 30 (discharge not determined because of insufficient data 

for definition of curve); minimum discharge, 1,700 second-feet at noon 

September 26 (gage height, 2.87 feet).

1924-1927: Maximum stage recorded, that of June 30, 1927; channels 

dry on numerous days in summers of 1924 and 1926.

DIVERSIONS AND REGULATION. Practically entire summer flow above station is 

appropriated by numerous diversions in Idaho Falls district. One small 

canal diverts between this and station at Clough ranch. Normal flow is 

augmented during irrigation season by release of stored water from Jackson 

Lake for use on Minidoka and Twin Falls tracts.

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

and observations discontinued during winter. Rating curves for medium 

and lower stages well defined by 16 discharge measurements made during 

current year and ranging from 2,000 to 13,000 second-feet; above 13,000 

second-feet rating not sufficiently well defined to warrant publication of 

discharge. Operation of water-stage recorder satisfactory except for few 

days in May. Daily discharge ascertained by applying mear daily gage 

height to rating table. Records good except for extremely high stages when 

gage heights only were obtained.

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 

one gage for No. 3 channel.

flow is augmented by release of stored water in Jackson Lake for use on 

Minidoka and Twin Falls tracts.

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

observations discontinued during winter. Two rating curves used, one from 

April 10 to June 3 and the other from June 14 to September 30. Rating 

curves well defined by 19 discharge measurements which range from 158 to 

6,430 second-feet and were made during current season. Operation of 

water-stage recorder satisfactory. Daily discharge ascertained by applying 

mean daily gage height to rating table; shifting-contro1 method used June 

4-13. Records good.

DIVERSION FROM SNAKE RIVER BETWEEN BLACKFOOT BRIDGE AND CLOUGH RANCH GAGING

STATIONS, IDAHO

Between Blackfoot Bridge and Clough ranch gaging stations, on-? small canal 

(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 the 

water. Records are available May 1, 1924, to September 30, 1927.

Stage-discharge relation affected by growth of aquatic plants. Rating curve 

fairly well defined. Gage read to hundredths daily May 8 to September 30. 

Records fair.

Blackfoot River is the only large tributary between station and mouth of 

Henrys Fork, 60 miles upstream. 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, 1927.

EQUIPMENT. Friez water-stage recorder on right bank; installed July 6, 1913. 

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 subject to slight shifts.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 12.62 feet 

from 6 a. m. to 1 p. m. July 1 (discharge, 33,700 second-feet); minimum 

stage, 2.31 feet at 12.30 a. m. October 1 (discharge, 618 second-feet).

1910-1927: 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 stage, 1.93 feet at 6 p. m. August 25, 1919 (difcharge, 118 secondfeet).
SNAKE RIVER 23

DIVERSIONS AND REGULATION. Practically entire natural summer f ow of river 

is diverted above station. Flow regulated by storage in Jackson Lake 

Reservoir and in Blackfoot-Marsh Reservoir on Blackfoot R'ver. Practically entire summer flow is released water from these reservoir.*',

ACCURACY. Stage-discharge relation changed; not seriously affected by ice. 

Rating curves are well defined by 32 discharge measurements covering range between 2,200 to 25,000 second-feet and made during year. Operation of water-stage recorder satisfactory. Daily discharge ascertained by 

applying mean daily gage height to rating rable, using shifting-control 

method October 1-31 and July 2 to September 30. Records good.

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 northwest of American Falls, and 32 miles above 

Minidoka Dam. Portneuf River, Bannock Creek, and about 2,500 secondfeet of spring water enter Snake River between this and the station at 

Clough ranch. Raft River enters 18 miles below Neeley.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. March 17, 1906, to September 30, 1927.

EQUIPMENT. Friez 8-day water-stage recorder on left bank. Discharge measurements made from cable at gage.
SNAKE RIVER 25

CHANNEL AND CONTROL. Bed at measuring section rough. Banks high. One 

channel at all stages. Control composed of lava rock partly overlain with 

coarse gravel; shifts slightly.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 11.37 feet 

6 to 9 p. m. July 2 (discharge, 33,800 second-feet); minimum discharge, 

about 180 second-feet for several hours October 31, March 20, and April 5, 

when gates were closed at American Falls Reservoir.

1906-1927: Actual maximum stage doubtful; maximum mean daily stage, 

13.5 feet June 20, 1918 (discharge, 48,400 second-feet); minimum discharge, that of October 31, 1926, March 20 and April 5, 1927.

DIVERSIONS AND REGULATION. Numerous canals near Blackfoot s.nd Idaho 

Falls divert practically entire natural summer flow of Snake River. American 

Falls Reservoir about 4 miles above station controls flow except for small 

fluctuations due to operation of power plant of Idaho Power Co. just below 

reservoir.

ACCURACY. Stage-discharge relation not entirely permanent; slightly affected 

by ice. Rating curve well defined by a great number of discharge measurements, of which 22, ranging from 1,000 to 25,000 second-feet, v^ere made 

during current year. Operation of water-stage recorder satisfactory except 

for short periods when well was frozen. Daily discharge ascertained by 

applying mean daily gage height to rating table, using shifting-control 

method July 10 to September 30. Records good except those for estimated 

periods, which are fair.

SNAKE RIVER 29

SNAKE RIVER AT MILNEK, IDAHO

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

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

Minidoka station and Milner and no sizable inflow between Milner and 

station near Twin Falls except seepage and spring water.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 10, 1909, to September 30, 1927.

EQUIPMENT. Friez recorder on left bank below highway bridge, installed May 

28, 1919. Discharge measurements made from cable 400 yards above gage, 

from foot plank midway between gage and cable, or by wading.

CHANNEL AND CONTROL. Bed at gage composed of lava rock, overlain with very 

light gravel deposits and occasional loose rock. Left bank higl and steep; 

right bank confines flow in narrow gorge below elevation 15 feet gage datum; 

full river width above that point. Control practically permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 20.83 feet at 

7 a. ra. July 4 (discharge, 26,000 second-feet); minimum stage, 1.56 feet at 

7 a. m. October 17 (discharge, 15 second-feet).

1909-1927: Maximum stage recorded, 20.1 feet (original gage) June 12, 

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

August 22-26 and October 23 and 24, 1924 (gage height, 1.50 feet).

DIVERSIONS AND REGULATION. Twin Falls Canals divert water at Milner Dam, 

just above station. During part of season practically entire flow of river 

is taken by these and other canals. Flow past the station during irrigation 

season is regulated at Milner Dam.

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

ice. Rating curves well defined by large number of discharge measurements 

made in previous years, and checked by 11 measurements ranging from 

extremely low stages up to 23,000 second-feet made during current year. 

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, using 

shifting-control method February 21 to March 4, July 19, 20, and 

September 20. Records good.

COOPERATION. Gage-height record and seven discharge measurements furnished 

by Twin Falls Canal Co. and North Side Canal Co. (Ltd.).

CHANNEL AND CONTROL. Bed composed of lava boulders and solid rock in deelava canyon; very rough. Control formed by low falls 70 feet below gage 

permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded dur'ng year, from water

stage recorder, 14.76 feet at 10 a. m. July 4 (discharge, 27,200 second-feet)

minimum stage, 1.35 feet at 1 p. m. October 29 (discharge, 462 second-feet)

1923-1927: Maximum stage and discharge, that of July 4, 1927; minimur

stage recorded, 0.80 foot May 16-20, 1924 (discharge, 378 second-feet).

DIVERSIONS AND REGULATION. No water diverted from r'ver between this an 

the station at Milner. Flow past station is regulated directly by diversion 

of the North and South Side Canals at Milner, where practically the entir 

flow is diverted during a large part of the irrigation season; flow at sue 

times consists of inflow and seepage between this and the station at Milnei
SNAKE RIVER 31

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

curve well defined between 370 and 15,000 second-feet, above which it is 

extended, based on 48 discharge measurements made during the years 1923 

to 1927, of which 7 measurements ranging from 477 to 14,400 second-feet were 

made during current year. 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 for days waterstage recorder was not operating. Records excellent except those for June, 

which are fair.

COOPERATION. Gage-height record furnished by Idaho Power Co.

Daily discharge, in second-feet, of Snake River near Kimberly, Idaho, for the year

ending September SO, 1927

SNAKE RIVER NEAR HAGERMAN, IDAHO

LOCATION. In sec. 2, T. 8 S., R. 13 E., one-eighth mile above Ows^y Bridge, 

just above Upper Salmon Falls, and 4 miles south of Hagerman, Gooding 

County. Big Wood River enters 11 miles downstream.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. August 24, 1912, to June 18, 1917; July 2f. 1919, to 

September 30, 1927.

EQUIPMENT. Friez water-stage recorder on right bank; installed Apr'1 20, 1921. 

Discharge measurements made from cable 100 feet below gage.

CHANNEL AND CONTROL. Control rocky; subject to slight change owing to 

moss growth.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 7.18 feet at 4 p. m. July 4 (discharge, 31,400 se-?ond-feet); 

minimum stage, 3.33 feet at 6 a. m. May 17 (discharge, 5,120 second-feet).

1912-1917, 1919-1927: Maximum stage recorded, 7.75 feet at 6 p. m. 

June 10, 1914 (discharge, 35,100 second-feet); minimum stag^, 3.1 feet 

July 15 to August 2, 1915 (discharge, 4,030 second-feet). Data insufficient 

in 1916 and 1917 for determination of maximum and minimum slages.

DIVERSIONS AND REGULATION. 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 above. Flow 

directly regulated by diversions of Twin Falls Canals at Milner.
34 SURFACE WATER SUPPLY, 1927, PART XII B

ACCURACY. Stage-discharge relation changed slightly December 8-11 and January 23-28; not affected by ice. Curve well denned between 5,000 and 20,000 

second-feet used January 29 to September 30, and curves parallel thereto 

used October 1 to December 7 and December 12 to January 22; denned by 

seven discharge measurements ranging from 5,100 to 19,900 second-feet made 

during current year. Operation of water-stage recorder satisfactory except 

for breaks in record during November, December, and January. Daily 

discharge ascertained by applying to rating table mean daily gage height 

determined by inspecting recorder graph. Records excellent except estimates, 

which are good.

SNAKE RIVER 35

SNAKE RIVER AT KING HILL, IDAHO

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

!fet:M/road station at King Hill, Elmore County. Big Wood River enters from 

tiorth 20 miles above station.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 13, 1909, to September 30, 1927.

EQUIPMENT. Inclined staff on right bank installed August 24, 1922. Discharge 

measurements made from cable 100 feet below gage.

CHANNEL AND CONTROL. Bed composed largely of gravel. Control is lava 

reef partly overlain with gravel; shifts slightly.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, from highwater mark, 13.4 feet July 4 (discharge, 34,100 second-feet); minimum stage 

5.6 feet May 6, July 23-26, 28-31 (discharge, 6,780 second-feet).

1909-1927: Maximum stage recorded, 16.3 feet June 22, 1918 (discharge, 

47,200 second-feet); minimum stage, 4.5 feet July 7-9, August 15, 16, 1910 

(discharge, 4,760 second-feet).

DIVERSIONS AND REGULATION. No large diversions for irrigation are made 

between this and the station at Milner. Flow regulated by diversions at 

Milner. During parts of irrigation season practically entire flow of river is 

appropriated, and flow at King Hill is derived largely from springs and seepage water from the Twin Falls tracts.

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

curve well defined below 28,000 second-feet by previous curve and 16 discharge measurements made during 1925, 1926, and 1927, 6 of which, 

ranging between 6,960 and 21,300 second-feet, were made during current 

year. Gage read to hundredths once daily. Daily discharge ascertained 

by applying daily gage height to rating table. Records good.

SNAKE RIVER NEAR MURPHY, IDAHO

LOCATION. In NW. % sec. 18, T. 2 S., R. 1 E., Ada Count}-, three-fourths mile 

below Swan Falls power plant, 9 miles northeast 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, 1927.

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

house on Glass ranch; installed July 31, 1924. Disci arge measurements 

made from boat at ferry cable 1 % 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. Banks not subject 

to overflow. Control premanent.

EXTREMES OF DISCHARGE. Maximum discharge estimated, 33,500 second-feet 

July 4-6, when water-stage recorder was not operating; minimum stage 

recorded, 0.96 foot 11 a. m. to noon August 6 (discharge, 6,250 second-feet). 

1912-1927: 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 r.bove station during 

low-water periods in 1919 to 1926, inclusive.

DIVERSIONS AND REGULATION. A number of small pumping plants divert water 

for irrigation between this and the station at King Hill. 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, changes are of short duration.

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

curve well defined by discharge measurements of previous years but not 

checked by measurements during current year. Operation of water-stage 

recorder satisfactory except as indicated in footnote tc table of daily discharge. Daily discharge ascertained by applying to rating table mean daily 

gage height obtained by inspection of recorder graph except for periods 

recorder was not operating. Records fair except those for estimated 

periods, which are poor.

COOPERATION. Gage-height record furnished by Idaho Power Co.

SNAKE RIVER AT WEISER, IDAHO

LOCATION. In sec. 31, T. 11 N., R. 5 W., one-third mile above w».gon bridge 

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

Sucker Creek, and Owyhee and Malheur Rivers enter Snake River from left 

and Boise, Payette, and Weiser Rivers from right.

DRAINAGE AREA. Not measured.
38 SURFACE WATER SUPPLY, 1927, PART XII B

RECORDS AVAILABLE. October 8, 1910, to September 30, 1927. Fragmentary 

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

EQUIPMENT. Inclined concrete gage on right bank. Elevf.tion of zero of gage 

is at 2,087.22 feet above mean sea level. Discharge measurements made 

from cable 200 yards below bridge or from bridge.

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

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 10.27 feet 

June 17 (discharge, 56,300 second-feet); minimum stage, 2.25 feet October 

1, 2 (discharge, 8,290 second-feet).

1910-1927: 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 gage (discharge about 100,000 second-feet).

DIVERSIONS AND REGULATION. Some water is diverted between Weiser and the 

station near Murphy by pumping. Diurnal fluctuations during periods of 

low water due to operations at Swan Falls power plant upstream.

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

curve well denned between 5,500 and 60,000 second-feet by preceding curve 

and five discharge measurements ranging from 9,010 1o 50,300 second-feet 

and made during current year. Gage read to hundredths once daily. Daily 

discharge ascertained by applying daily gage height to rating table. 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 StateDepartment of Reclamation to facilitate distribution of the water. Records are 

available from June 1, 1919, to September 30, 1927.

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

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

read to hundredths daily except during September, when occasional readings 

were made. Records good.

DIVERSIONS FROM FAIL RIVER ABOVE GAGING STATION NEAR SQUIRREL, IDAHO

Above gaging station near Squirrel three 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 the water. Records are available 

from June 1, 1919, to September 30, 1927.

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

Rating curves fairly well defined. Gages read daily to hundr^dths except during 

September, when occasional readings were made. Records food.

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

gaging station near Squirrel, Idaho, for irrigation season of 1927

DIVEBSIONS FEOM FAIL EIVEE BETWEEN SQUIREEI AND CHESTEE GAGING STATIONS, IDAHO

Between Squirrel and Chester gaging stations 10 separate canals divert water 

from Fall River for irrigation. Gaging stations are maintained at the 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, 1927.

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

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

Gage read to hundredths daily except during September, wh?n occasional readings were made. Records good.

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

Squirrel and Chester gaging stations, Idaho, for irrigation season of 1927

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

OP RIVER. IDAHO

Between St. Anthony gaging station and mouth of Teton River 15 separate 

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

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

from June 1, 1919, to September 30, 1927.

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

Rating curves are fairly well denned. Gage read to hundredths daily except 

during September, when occasional readings were made. Records fair.

DRAINAGE AREA. 220 square miles (measured on United States Geological 

Survey map of Mud Lake Basin).

RECORDS AVAILABLE. April 15, 1921, to September 30, 1927.

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

May 8, 1927. Prior to May 8, 1927, gage was vertical staff attached to cottonwood tree on left bank, 175 feet below recorder site. Discharge measurements made from highway bridge at Dubois or by wading.

CHANNEL AND CONTROL. Bed composed of lava rock and gravel. P^nks steep 

and brushy; one channel at all stages. Control fairly well defined but 

occasionally fouled by drift.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 3.2 feet April 

27, 28 (discharge, 293 second-feet); minimum stage, 0.58 foot July 21-23 

(discharge, 5 second-feet). Lower stage may have occurred during period 

of no record.

1921-1927: Maximum discharge, 637 second-feet May 20, 1922 (gage 

height, 4.9 feet); stream reported dry August 3 to about November 30, 

1924.

DIVERSIONS AND REGULATION. A few small diversions several miles upstream. 

During summer practically entire flow is diverted below gage for irrigation.

ACCURACY. Stage-discharge relation changed slightly on April 27'and 28; affected by ice; record discontinued during winter. Rating curve used prior 

to April 27 is well denned by several discharge measurements made in 1925 

and 1926 and checked closely by two measurements made in Mr.rch of current year. Curve used subsequent to May 8 is well defined by nine discharge 

measurements, ranging from 8.2 to 169 second-feet, made dur'ng current 

year. Gage read to hundredths once daily prior to May 8; thereafter operation of wrater-stage recorder was satisfactory. Daily discharge ascertained 

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

determined from inspection of recorder graph except as indicated in footnote to table of daily discharge; shifting-control method, defined by two 

measurements, used April 27 to May 8. Records excellent May 8 to June 

30; others good except those for estimated periods, which are fair.

BIG LOST RIVER (EAST CHANNEL) ABOVE MACKAY RESERVOIR, N"?AR MACKAY, IDAHO

LOCATION. In sec. 32, T. 8 N., R. 23 E., 3 miles above Mackay Dam, above 

flow line of reservoir, and lY-i miles above Mackay, Custer County.

DRAINAGE AREA. -Not measured.

RECORDS AVAILABLE. May 9, 1919, to September 30, 1927.

EQUIPMENT. Stevens 8-day water-stage recorder on right bank. Discharge 

measurements made from suspension footbridge 20 feet below gage or by 

wading.

CHANNEL AND CONTROL. Bed composed of gravel; fairly permanent. One channel at low and medium stages; right bank overflowed at high stages. Control 

fairly well defined.

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

3.18 feet June 13 (discharge, 800 second-feet); channel reported dry, December 20 to noon May 17.

1919-1927: Maximum stage recorded, 3.37 feet June 16, 1922 (discharge, 

999 second-feet); no flow April 27 to May 16, 1920, in winter of 1923, for 

long periods in 1924, January 1 to May 7, 1925, January 11 to May 2, 1926, 

and December 20, 1926, to May 17, 1927.

DIVERSIONS AND REGULATION. No diversions between gage and reservoir. 

Several canals divert water in vicinity of Chilly above "dry beds" which 

extend from a few miles above gage to a point about 15 miles above. No 

regulation except as affected by diversions above gage.

ACCURACY. Stage-discharge relation changed very slightly during frozen period 

when channel was practically dry. Rating curve used pnor to December 20 

is fairly well defined by measurements made in 1926 and shape of previous 

purve. Rating curve used subsequent to May 16 is well defined below and 

extended above 750 second-feet, by six discharge measurements made during 

year. 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 indicated in footnote to table of daily 

discharge. Records good except those for estimated period, which are poor.

COOPERATION. Gage-height record and two 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 the record for west channel of Big Lost 

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

show the entire flow of Big Lost River at this point. The combined flow of Big 

Lost River and Warm Spring Creek represents practically tl e entire surface flow 

at this point into Mackay Reservoir, situated 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 71, 76, and 78, respectively. For combined flow of both channels 

of Big Lost River and both channels of Warm Spring Creek see page 73.

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 1% miles above Mackay, Custer County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 9, 1919, to September 30, 1927.

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

1920. Discharge measurements made from suspension footbridge just above 

gage or by wading.
72 SURFACE WATER SUPPLY, 1927, PART XII B

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 durjng year, 

3.00 feet June 14 (discharge, 493 second-feet); minimum stage, 0.93 foot 

April 5 to May 5 and May 14-16 (discharge, 15 second-feet).

1919-1927: Maximum discharge (estimated), 1,200 second-feet June 5-16, 

1921, when water-stage recorder was not operating (gage height, from highwater mark on gage, 4.45 feet); minimum stage, 0.84 foot May 3-6, 1925 

(discharge, 13 second-feet).

DIVERSIONS AND REGULATION. No diversions between station and reservoir. 

Several canals divert water above "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.

ACCURACY. Stage-discharge relation changed very slightly Fsptember 6-20; not 

affected by ice owing to spring inflow above gage. Rating curve used prior 

to September 7 is well defined below 500 second-feet by nine discharge 

measurements made during 1926 and 1927, of which seven were made during 

the current year. Operation of water-stage recorder satisfactory except 

for short periods when recorders clock was not running properly. Daily 

discharge ascertained by applying to rating table mean daily gage height 

obtained by inspection of recorder graph except as noted in footnote 

to daily discharge table; shifting-control method usei September 6-30. 

Recorded 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 channe1 of Big Lost River 

and with the record for east and west channels of Warm Spr'ng Creek will show 

the entire surface flow of Big Lost River at this point. The combined flow of 

Big Lost River and Warm Spring Creek represents practically the entire flow at 

this point into Mackay Reservoir, situated 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 70, 76, and 78, respectively. For conbined flow of both 

channels of Big Lost River and Warm Spring Creek see page 73.

BIG LOST EIVEE BELOW MACKAY RESERVOIR, NEAR MACKAY, IDAHO

LOCATION. In sec. 18, T. 7 N., R. 24 E., 450 feet below Oleson suspension bridge,, 

half a mile above heading of Streeter ditch, 1% miles below Mackay Dam, and 

2% miles above Mackay, Custer County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. December 1, 1903, to August 31, 1906; May 12, 1912, to 

April 29, 1913; January 1, 1919, to September 30, 1927. From April 29, 

1913, to March 15, 1915, records were obtained 1 mile below present site. 

Streeter ditch diverts water between these two points.

EQUIPMENT. Friez water-stage recorder on left bank installed May 4, 1920. 

Discharge measurements made from cable just below gage or by wading.

CHANNEL AND CONTROL. Bed composed of gravel; shifts occasionally. Moss 

growth at times affects stage-discharge relation.

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

4.14 feet June 17 and 18 (discharge, 1,430 second-feet); minimum stage, 1.23 

feet November 5-8 (discharge, 25 second-feet).

1903-1906, 1912-1915, 1919-1927: Maximum stage recorded, 5.79 feet 

June 10, 1921 (discharge, 2,990 second-feet); minimum stage, that of November 5-8, 1926.

DIVERSIONS AND REGULATION. Numerous diversions above MackajT Reservoir, 

but Sharp ditch is only diversion between gage and reservoir. Flow past 

gage regulated by operation of gates in Mackay Dam. Prior to 1917 regulation from storage above was practically negligible.

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

Rating curve is well defined by seven discharge measurements ranging between 

82 and 1,370 second-feet and made during year. Operation of water-stage 

recorder satisfactory. Daily discharge ascertained March 8 to July 11 by 

applying to rating table mean daily gage height determined by inspecting 

recorder graph, and for rest of year by shifting-control method. Records 

good.

COOPERATION. Gage-height record and two discharge measurements furnished 

by water commissioner for Big Lost River.

WARM SPRING CREEK (EAST CHANNEL) NEAR MACKAY, IDAHO

LOCATION. In NE. % sec. 5, T. 7 N., R. 23 E., 500 feet above junction with west

channel of Warm Spring Creek, 3% miles above Mackay Dam, and 7l/2 miles

northwest of Mackay, Ouster County. 

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 1, 1919, to September 30, 1927. 

EQUIPMENT. Vertical staff on right bank; installed May 3. 1920. Discharge

measurements made from suspension bridge 125 feet above gage or by wading. 

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

covered with brush. One channel at all stages. Channel congested by growth

of moss during summer.
TRIBUTARY BASINS 77

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 2.54 feet June 

14 (discharge, 154 second-feet); minimum discharge, 15 second-feet April 

15-19 (gage height, 1.28 feet April 16).

1919-1927: Maximum discharge recorded, 225 second-feet June 15, 1922; 

minimum discharge, 9 second-feet May 8, 9, 13, and 14, 1919, and May 18-21, 

1920.

DIVERSIONS AND REGULATION. Natural flow practically all diverted during irrigation season. Flow during summer represents return flow from irrigation 

above. Entire flow stored in Mackay Reservoir 3^ miles below. No regulation.

ACCURACY. Stage-discharge relation affected by growth of moss and by brush 

along banks; not affected by ice owing to inflow of springs above. Rating 

curve well defined. Seven discharge measurements, ranging from 22.4 to 

122 second-feet, were made during current year. Gage read to hundredths 

once or twice a week. Daily discharge ascertained by shifting-control 

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

only fair because of infrequent gage readings.

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 the record for west channel of Warm Spring 

Creek and east and west channels of Big Lost River will show the entire surface 

flow of Big Lost River which enters Mackay Reservoir a short distance below. 

For record from station on west channel of Warm Spring Creek and east and west 

 channels of Big Lost River see pages 70, 71, and 78, respectively. For record of 

combined flow of both channels of Big Lost River and Warm Spring Creek see 

page 73.

411 second-feet); minimum discharge, 61 second-feet May 7, 1925.

DIVERSIONS AND REGULATION. Practically entire flow diverted during irrigation season. Flow during summer represents return flow from irrigation 

above. Entire flow passing gage impounded in Mackay Reservoir below. 

No regulation.

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

to inflow from springs. Standard rating curve well defined. Seven discharge measurements ranging from 80.6 to 219 second-feet, were made 

during current year. Operation of water-stage recorder satisfactory. 

Daily discharge ascertained by shifting-control method. Records good.

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 the record for east channel of Warm 

Spring Creek and the record for east and west channels of Pig Lost River will 

show practically entire surface flow of Big Lost River which enters Mackay 

Reservoir a short distance below. For record from stations on east channel of 

Warm Spring Creek and on east and west channels of Big Lost River, see pages 

70, 71, and 76, respectively. For record of combined flow o* both channels of

PORTNEUF RIVER AT POCATELLO, IDAHO

LOCATION. In sec. 27, T. 6 S., R. 34 E., at highway bridge at foot of Carson 

Street, in west end of Pocatello, Bannock County.

DRAINAGE AEEA. Not measured.

HECORDS AVAILABLE. August 31, 1911, to September 30, 1927. For station 

1 mile upstream, May 18, 1897, to October 14, 1899.

EQUIPMENT. Vertical staff attached to pile of Carson Street highway bridge 

near left bank; installed September 8, 1919. From May 14 to September 30, 

1927, a Stevens 8-day recorder temporarily installed on left bank one-third 

mile below bridge staff and at different datum was used. Discharge measurements made from cable 500 feet below recorder site, from Carson Street 

bridge, or by wading.

 CHANNEL AND CONTROL. Bed composed of rocks and boulderr; very rough. One 

channel except at extremely high stages when left b<vnk is overflowed. 

Control shifts.
TRIBUTARY BASINS

EXTREMES OF DISCHARGE. Maximum stage recorded during year, £.70 feet May 

1-3 (discharge, 821 second-feet); minimum stage, 0.95 foot (at recorder site), 

at 6 a. m. July 20 (discharge, 56 second-feet).

1911-1927: Maximum stage recorded, 7.8 feet May 30, 1917 (discharge,, 

in excess of 2,000 second-feet during period May 13 to June 14, 1917, when 

left bank was overflowed); minimum stage, 1.92 feet June 24 and 28, 1919 

(discharge, 44 second-feet).

1897-1899: Maximum stage recorded, 12.80 feet May 18, 1897 (discharge, 1,880 second-feet); minimum stage, 6.10 feet July 4-11, 13, 17, 

and 18, 1898 (discharge, 14 second-feet).

DIVERSIONS AND REGULATION. Numerous ranch diversions above gage. The 

largest single diversion is canal of Portneuf-Marsh Valley Canal Co., which 

irrigates land near Downey. No regulation below head of Portneuf-Marsh 

Valley Canal Co.'s canal. Storage reservoir of company near Chesterfield 

has capacity of about 28,000 acre-feet.

ACCURACY. Stage-discharge relation not permanent; affected by growth of 

moss and by ice. Hating curve used October 1 to May 13, is fairly well1 

defined by discharge measurements made in 1926 and two measurements 

made in March and April of the current year; curves used subsequent to May 

13 poorly denned, based on 21 measurements ranging from 104 to 704 secondfeet and made after May 13 of current year. Staff gage read to half-tenths 

one to three times a week, October 1 to May 13; operation of water-stage 

recorder satisfactory for rest of year. Daily discharge December 1 to 

May 13 ascertained by applying to rating table daily staff gage height 

or mean daily gage height determined by inspection of recorder graph, and 

for rest of year by shifting-control method, except as indicated in footnote 

to table of daily discharge. Records fair.

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% milns northwest of Twin 

Falls, Twin Falls County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. March 27, 1922, to September 30, 1927.

GAGE. Friez water-stage recorder on right bank; installed July 31, 1922. Discharge measurements made from highway bridge.

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

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

Control formed by lava reef covered in part by boulders and brush growth; 

fairly permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, from highwater marks on bank, 4.5 feet September 21 (discharge, 984 second-feet) 

minimum stage, 0.80 foot from noon to 6 p. m. Ap^il 23 (discharge, 9£ 

second-feet).

1922-1927: Maximum discharge recorded, that of September 21, 1927: 

minimum discharge, 90 second-feet from 11 p. m. April 1 to 2 a. m. April 

2, 1926 (gage height, 0.81 foot).

DIVERSIONS AND REGULATION. 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 P;de Twin Falls tract. 

At times waste water from South Side Twin Falls Canp.l which crosses Rock 

Creek about 10 miles above the station causes appreciable changes in stage.

ACCURACY. Stage-discharge relation changed several times after April 2; not 

affected by ice. Two rating curves well defined between 100 and 500 secondfeet, above which they are extended. Ten discharge measurements ranging 

from 115 to 446 second-feet were made during current year. Operation of 

water-stage recorder satisfactory except for short periods. Daily discharge 

ascertained October 1 to April 2 and June 22 to September 16 by applying 

to rating table mean daily gage height determined from inspection of recorder 

graph, and for rest of year by shifting-control method. Records good except those for stages above 500 second-feet, which are fair, and those for 

estimated periods, which are poor.

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

SALMON FAILS CREEK NEAR SAN JACINTO, NEV.

LOCATION. In sec. 23, T. 47 N., R. 64 E., in canyon 200 yards b^low 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, 1927.

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

1924. Discharge measurements made from cable at gage or by wading.

CHANNEL AND CONTROL. Bed composed of gravel. Left bank subject to overflow at high stages. Control shifts slightly.
98 SURFACE WATER SUPPLY, 1927, PART XII B

EXTREMES OF DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 5.92 feet at 3 to 5 p. m. May 20 (discharge, 818 second-feet); 

minimum discharge, 24 second-feet August 12-14 and September 17 (gage 

height, 2.46 feet).

1909-1916, 1919-1927: 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).

DIVERSIONS AND REGULATION. A large number of diversions on ranches of 

Utah Construction Co. above station appropriate a large portion of lowwater flow of Salmon Falls and Shoshone Creeks. No regulation except 

that due to diversions. The Salmon Dam of Salmon Plver Canal Co., 15 

miles below station, forms a reservoir having a capacity of about 180,000 

acre-feet.

ACCURACY. Stage-discharge relation changed slightly February 20-22; not 

affected by ice. Rating curve applicable October 1 to February 19 is well 

denned by discharge measurements made in 1926 and two measurements 

made during October of the current year; curve applicable February 23 to 

September 30 is well defined between 20 and 850 second-feet based on 15 

measurements ranging from 33.4 to 800 second-feet and made during this 

period. Operation of water-stage recorder very satisfactory except for 

periods in December, January, and February. Daily discharge ascertained 

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

of recorder graph. Shifting-control method used February 20-22. Records 

excellent after February 22; others good except those fo" estimated periods, 

which are fair.

COOPERATION. Gage-height record and 11 discharge measurements furnished 

by Salmon River Canal Co. (Ltd.).

BIS WOOD RIVER AT HAIIEY, IDAHO

LOCATION. In SW. % 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, 1927.

EQUIPMENT. Vertical staff on right bank, installed October 2, 1922. Discharge 

measurements made from bridge or by wading.

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

Banks low; covered with light brush. Log cribbing along l?ft 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 discharge recorded, 3,060 second-feet, 

occurred at 6.50 a. m. May 17, 6 p. m. June 8, 8 a. m. June 12, 7.40 a. m. 

June 12, and 7 a. m. June 14 (maximum gage height, 5.70 feet recorded at 

6.50 a. m. May 17); minimum recorded stage, 0.40 foot October 16-21 

(discharge, 3.4 second-feet). A lower discharge may have occurred during 

winter.

1915-1927: Maximum discharge, 3,560 second-feet June 12, 1921 (gage 

height, 5.70 feet); minimum discharge, 0.1 second-foot September 10-20 

and October 2-9, 1924.

DIVERSIONS AND REGULATION. 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 belov^ station. A 

record of the flow of Big Wood Slough is being obtained (see p. 112), and 

the total flow of Big Wood River is represented by amount of water passing 

both stations. 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.
100 SURFACE WATER SUPPLY, 1927, PART XII B

ACCURACY. Stage-discharge relation changed somewhat gradually during flood 

period from April 28 to June 21; not seriously affected by ice. During the 

current year 22 discharge measurements were made, of which four closely 

checked well-defined rating curve used prior to April 28; 13 measurements 

were used in developing curve well defined between 130 and 2,600 secondfeet, applicable after June 21, and five measurements denned curves applicable during the period of shifting control. Gage read to hundredths twice 

daily April 25 to September 16 and once daily at other times except December 

9 to March 3, when flow consisted only of leakage through diversion dam 

above. Daily discharge ascertained by applying daily ard mean daily gage 

height to rating table except as noted above. Record? good except those 

for estimated periods, which are poor.

COOPERATION. Twelve 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.

CHANNEL AND CONTROL. Bed composed of coarse gravel. Banks clean; may 

be overflowed at extremely high stages. Control shifts occasionally.

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

recorder, 4.04 feet at 6 p. m. May 17 (discharge, 2,620 second-feet); minimum 

stage recorded, 1.16 feet October 7 (measured discharge, 34.8 second-feet). 

1911-1927: Maximum stage recorded, 6.07 feet at 7 p. m. June 16, 1921 

(discharge, 3,660 second-feet); minimum discharge, 25 second-feet April 

22-24, 1920; lower flow may have occurred on a day of no record.

DIVERSIONS AND REGULATION. Numerous diversions for irrigation above 

station. Flood waters stored in Magic Reservoir. No regulation except as 

effected by diversions above station.

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

between 100 and 2,400 second-feet by 10 discharge measurements ranging 

from 138 to 2,160 second-feet and made during current year. Operation of 

water-stage recorder satisfactory. Daily discharge ascertained by applying 

to rating table mean daily gage height obtained by inspection or recorder 

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

excellent.

COOPERATION. Gage-height record and seven discharge measurements furnished 

by water master for Big Wood and Little Wood Rivers.

LOCATION. Iii NE. % SE. % sec. IS, T. 2 g., R. IS E.. Blaine County, 18 miles 

northwest of Richfield, Lincoln County.

DRAINAGE AREA. 1,500 square miles (furnished by Idaho Irrigation Co.).

RECORDS AVAILABLE. February 3, 1909, to September 30, 1927. Prior to April 

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.

EQUIPMENT. 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; when 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. 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.).

limits as determined by 22 discharge measurements made durirg the current 

year; not affected by ice. Standard rating curve is well defined below 2,500 

second-feet and extended above. Operation of water-stage r?corder satisfactory except during winter, when readings were discontinue*:1 . Daily discharge ascertained by applying to rating table mean daily gage height 

determined by inspection of recorder graph except for April 7 when discharge 

was determined by averaging results obtained by applying hourly gage heights 

to rating table. Records good except those during winter, which are fair.

COOPERATION. Gage-height record and 18 discharge measurements furnished by 

water master for Big Wood and Little Wood Rivers.

RECORDS AVAILABLE. April 21, 1921, to September 30, 1927. No flow passed 

gage during 1926.

EQUIPMENT. Vertical staff on right bank. Discharge measurements made 

from cable 300 feet below gage or by wading.

CHANNEL AND CONTROL. Bed composed of lava rock partly covered with gravel. 

One channel at all stages. Control formed by lava-rock riffle about 100 

feet below gage; fairly permanent. Point of zero flov at gage height, 

approximately 0.5 foot.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 6.00 feet at 

6.50 a. m. May 19 (discharge, 2,100 second-feet); channel reported dry 

throughout year except for days for which discharge is given.

1921-1927: Maximum stage recorded, 12.79 feet (old datum) June 13, 

1921 (discharge, 3,330 second-feet); channel practically dry except during 

irrigation seasons each year, and then only when Lincoa n Canal does not 

divert the entire flow of river.

DIVERSIONS AND REGULATION. Numerous diversions for irrigation made above 

and below station. Richfield and Lincoln Canals are main diversions 

between station and Magic Dam. Lincoln Canal, completed in spring of 1925, 

diverts all the flow, except during high water, around station on right bank 

to conserve channel losses in the natural stream bed throughout an 8-mile 

stretch of the river. Flow regulated by diversions above and by operation 

of head gates at Magic Dam 13 miles above.

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

between 150 and 2,000 second-feet, based on four discharge measurements 

made during current year and shape of previous curves. Gage read to hundredths twice daily. Daily discharge ascertained by applying mean daily 

gage height to rating table, except as indicated in footnote to table of daily 

discharge. Records good.

COOPERATION. Gage-height record and two discharge measurements furnished 

by water master for Big Wood and Little Wood Rivers.

BIG WOOD RIVER BELOW NORTH GOODING CANAL, NEAR SHOSHONE, IDAHO

LOCATION. In sec. 15, T. 4 S., R. 18 E., 300 yards below headwcrks of North 

Gooding Canal, 13 miles northeast of Shoshone, Lincoln County, and 14 

miles below Magic Dam.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. January 1, 1911, to September 30, 1927.

EQUIPMENT. Gurley 7-day water-stage recorder on right bank, installed July 5,, 

1920. Discharge measurements made from cable about 100 feet below gage 

or by wading.

CHANNEL AND CONTROL. Bed composed of lava rock; practically permanent; 

rough. At extreme high stages water overflowed above North Gooding 

diversion dam into secondary channel to left of gage. Control well defined.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 7.35 feet at 6.05 p. m. on May 18 and 6.35 a. m. on May 19 

(discharge, 1,640 second-feet); channel reported dry except during period of 

recorded flow as shown in table of daily discharge.

1911-1927: Maximum stage recorded, 15.0 feet (old datum) May 18, 1921 

(discharge, 3,180 second-feet); no flow during several different periods.

DIVERSIONS AND REGULATION. Station is below all diversions of Big Wood 

Canal Co. North Gooding and Richfield Canals divert water between 

station and Magic Dam. Lincoln Canal, which was designed to carry about 

700 second-feet and was completed in spring of 1925, heads 7 miles below 

Magic Dam and empties directly into North Gooding Canal at its head 

gates a quarter of a mile above station; it diverts water on right bank of 

Big Wood River for the purpose of conserving loss in the natural channel 

throughout this stretch of the river. Flow past station is regulated by gates 

at Magic Dam and head gates of the North Gooding and Richfield Canals.

BIG WOOD SLOUGH AT HAHEY, IDAHO

LOCATION. In sec. 9, T. 2 N., R. 18 E., at highway bridge one-eighth milenortheast of steel highway bridge across Big Wood R: ver and one-eighth 

mile southwest of Hailey, Blaine County.

RECORDS AVAILABLE. June 11, 1915, to September 30, 1927.

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

highway bridge; installed August 3, 1923. Discharge measurements madefrom 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 wood stave water pipe, laid in bed of stream about 15 feet below 

gage; changes slightly. Protruding willow stumps near right bank collectdrift occasionally, which affects stage-discharge relation.

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

7.30 a. m. April 26 (discharge, 312 second-feet); minimum discharge, 27" 

second-feet August 24-28, in the afternoon of August 29-31, and morning, 

of September 7 (gage height, 1.12 feet).

1915-1927: Maximum stage recorded, 3.00 feet June 6, 1921 (discharge; 

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

DIVERSIONS AND REGULATION. No diversions. The amount of water passing 

gage is affected by load at power plant half a mile upstream; considerable 

fluctuation. Main river station is affected inversely by any such regulation,, 

so that the accuracy of the summation of the two records is presumably 

affected only slightly by this factor.

ACCURACY. Stage-discharge relation changed frequently during year; slightly 

affected by ice January 22-30. During the year 15 discharge measurements: 

were made which closely defined the rating curves applicable between shiftsin the stage-discharge relation. Gage read to hundredths twice daily April 

25 to September 16 and once daily at other times. Drily discharge ascertained by applying daily or mean daily gage height to rating table, except 

for ice-affected period for which it was estimated. Records good except 

those for November to April 10, which are 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 sho\" entire flow of river 

at this point. For record from station on main river see pi.ge 99. For record 

of combined flow of Big Wood River and Big Wood Slough see page 101.

LINCOLN CANAL NEAR RICHFIELD, IDAHO

LOCATION. In sec. 9, T. 3 S., R. 18 E., at head of canal, 100 yard^ east from 

Shoshone-Hailey highway, 5% miles below Magic Dam, and 12 miles northeast of Richfield, Lincoln County.

RECORDS AVAILABLE. April 15, 1925, to September 30, 1927.

EQUIPMENT. Gurley 7-day water-stage recorder on right bank 400 feet below 

head gates. Discharge measurements made from cable 400 feet below gage 

or by wading.

CHANNEL AND CONTROL. Bed composed of lava covered by gravel. One channel 

at all stages. Control not definitely defined.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 4.00 feet at 4 p. m. May 28 (discharge, 706 second-feet); 

probably no flow October 1 to November 14, November 18 to April 22, and 

September 17-30.

1925-1927: Maximum stage and discharge recorded, that of May 28, 1927; 

no flow for long periods each year.

DIVERSIONS AND REGULATION. Flow regulated by gates at head of ci.nal.

ACCURACY. Stage-discharge relation changed very slightly during winter; no 

flow during ice period. Rating curve used November 15-17 is well defined 

by discharge measurements made in 1926; curve used after Apr'1 22 is well 

defined below 600 second-feet and is based on preceding curve and 11 discharge measurements ranging from 204 to 573 second-feet made during 

the current year. Operation of water-stage recorder satisfactory; daily 

staff gage readings used November 15-17. Daily discharge ascertained by 

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

determined by inspection of recorder graph. Records good except those for 

November, which are fair.

COOPERATION. Gage-height record and eight discharge measurements furnished 

by water master for Big Wood and Little Wood Rivers.

Lincoln Canal diverts water from right bank of Big Wood River in sec. 9, 

T. 3 S., R. 18 E., from which point water is carried 10 miles, approximately 

paralleling the river to head of North Gooding Canal in sec. 15, T. 4 S., R. 18 E. 

Lincoln Canal was completed in spring of 1925 and used thereafter for conserving large channel losses in the natural stream bed of this stretch of river during 

irrigation seasons.

minimum stage, 0.39 foot October 9 (measured discharge, 17.5 second-feet). 

1922-1927: 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).

DIVERSIONS AND REGULATION. Numerous irrigation diversions above and below. 

A small ditch for the Shoshone water supply diverts from left bank directlybelow gage. No regulation except that due to diversions.

ACCURACY. Stage-discharge relation permanent; observations discontinued 

during winter. Rating curve well defined between 15 and 400 second-feet by 

nine discharge measurements ranging from 17.5 to 334 second-feet and made 

during current year. Infrequent readings to hundredths from staff gage 

October 9 to 26. Operation of water-stage recorder satisfactory April to 

September. Daily discharge ascertained by applying to rating table daily 

or mean daily gage height except as noted in footnote to table of daily discharge. During period water-stage recorder was operated mean daily gage 

height determined by inspection of recorder graph. Records good.

COOPERATION. Gage-height record and discharge measurements furnished by 

water master for Big Wood and Little Wood Rivers.

LOCATION. In sec. 2, T. 1 N., R. 22 E., 1% miles above mouth of West Fork

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

miles northeast of Carey, Blaine County.

DRAINAGE AREA. About 56 square miles (measured on br,se map of Idaho). 

RECORDS AVAILABLE. May 3, 1920, to September 30, 1927. 

EQUIPMENT. Stevens 8-day water-stage recorder on right bank; installed

March 22, 1926. Discharge measurements made by wading. 

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

may be overflowed at high stages. Control formed by 18-foot Cippoletti

weir set in concrete, 8 feet below gage.
TRIBUTARY BASINS 123

EXTREMES OF DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 1.66 feet from 4 to 6 a. m. April 28 (discharge, 138 secondfeet); channel reported dry from 5 p. m. October 17 to 11 p. m. October 27. 

1920-1927: Maximum stage recorded from water-stage recorder, 1.78 

feet 9 a. m. to 1 p. m. May 6, 1922 (discharge, 158 second-f e?.t); channel 

reported dry from 1 to 7 a. m. September 9, from 8 p. m. September 9 to 6 

a. m. September 12, and from 5 p. m. October 17 to 11 p. m. October 27, 

1926.

DIVERSIONS AND REGULATION. Several small diversions above gage. No regulation except that caused by diversions.

ACCURACY. Stage-discharge relation changed slightly June 17 to July 13; not 

seriously affected by ice. Two rating curves used during ye?,r, one from 

October 1 to June 16 and the other from July 14 to September 30; based on 

four discharge measurements, ranging from 5.7 to 62.2 second-feet and made 

during the current year, and shape of former curve. Water-stage recorder 

operated satisfactorily October 1 to November 2 and April 7 to September 

30. During intervening period staff gage read to hundredths at infrequent 

intervals. Daily discharge determined by applying to rating table daily 

staff-gage reading or mean daily gage height determined by inspection of 

recorder graph; shifting-control method used June 17 to July 13. Records 

good except those for estimated periods, which are poor.

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

NOTE. Crooks Slough, which carries some of the water diverted or overflowed from Fish Creek above 

gage on left bank, contributed the following amounts of water as measured into Carey Valley Reservoir: 

April, 180 acre-feet; May, 30 acre-feet; June, 260 acre-feet; no flow from July to September.

FISH CHEEK NEAR CABEY, IDAHO

LOCATION. In sec. 22, T. 1 N., R. 22 E., l/l 2 miles below dam of Carey Valley 

Reservoir 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, 1927. Several discharge measurements obtained in 1921 and 

1922.

EQUIPMENT. Stevens 8-day water-stage recorder immediately above highway 

bridge on left bank; installed April 29, 1926. 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. Shortly prior to May 6, 1927, 

length of weir crest was increased from 17.64 to 18.00 feet. Zero of gage 

set at mean elevation of weir crest.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 1.91 feet May 19 (discharge, 170 second-feet); minimum discharge (estimated), 1.0 second-foot October 14-16, wher water was diverted 

through sluice gates in weir. Lower discharge may have occurred at times 

during period of no record.

1919-20, 1923-1927: Maximum stage recorded, that of May 19, 1927; 

channel reported practically dry at times when gates are closed in dam 

above.

DIVERSIONS AND REGULATION. No diversions between station and dam. Flow 

completely regulated by operation of gates in dam.

ACCURACY. Stage-discharge relation changed slightly by increasing length of 

weir control shortly before May 6; records discontinued December 1 to 

May 5. Two well-defined rating curves used, the first applicable October 1 

to November 30 and the other applicable after May 5; both curves are based 

on shape of standard Cippoletti weir formula and discharge measurements, 

of which three ranging from 7.2 to 129 second-feet were made during 

the current year. Operation of water-stage recorder satisfactory except for 

short periods in November, May, July, and August. Daily discharge 

ascertained by applying to rating table daily staff gage 1 ^ight or mean daily 

gage height determined by inspection of recorder graph. Records good.

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

WEST FORK OF FISH CREEK NEAR CAREY, IDAHO

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

Creek, 2 miles above dam of the Carey Valley Reservoir Co., r,nd 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, 1927. Discharge

measurements only available in 1923. 

EQUIPMENT. Vertical staff gage on left bank; installed May 14, 1926; set to

read actual depths over weir crest. Discharge measurements made by

wading.
126 SURFACE WATER SUPPLY, 1927, PART XII B

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

at all stages. Control formed by a 4-foot Cippoletti weir for stages below 

0.29 foot, and by 12-foot weir for higher stages.

EXTREMES OF DISCHARGE. Maximum discharge during year, estimated 30 

second-feet, April 26 to May 3; minimum discharge, 0.2 second-foot October 

1 to November 7, July 11-17, 27-29, August 1-12, 16-24, and September 

1-30 (gage height, 0.05 foot October 5). Probably not actual extremes.

1920-1922, 1924-1927: 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.

DIVERSIONS AND REGULATION. One small diversion above gage. No regulation.

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

curve for stages below 2.2 second-feet determined f~om standard weir 

formula, and for stages above it is based on two discharge measurements 

made during the current year at 13.9 and 4.4 second-feet, respectively. 

Gage read to hundredths one to three times a week. Daily discharge determined by applying daily gage height to rating table except for days of 

missing records, for which discharge was interpolated or estimated as noted 

in footnote to table of daily discharge. Records fair.

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

OWYHEE RIVER NEAR OWYHEE, OREG.

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

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

DRAINAGE AREA. About 11,100 square miles. Watershed poorly defined on 

available maps.

RECORDS 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, 1927.
TRIBUTARY BASINS 133

EQUIPMENT. Chain gage on upstream side of highway bridge. Discharge measurements made from bridge or by wading.

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

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 8.3 feet April 4 

(discharge, 7,750 second-feet); minimum stage recorded, 2.0 feet August 4 

(discharge, 9 second-feet).

1890-1893, 1895-96, 1903-1916, 1920-1927: Maximum stage recorded, 

12.9 feet March 2, 1910 (discharge, 23,200 second-feet); minimum discharge, 

no flow July 7, 19, August 14-16, 1924, and July 5-6, 1926.

DIVERSIONS AND REGULATION. Owyhee Canal, the principal diversion immediately above station, heads about 6 miles above gage. This canal diverts 

practically entire natural low-water flow of the river. (See p. 134.) Variation in the flow may be caused by manipulation of gates at head of Owyhee 

Canal.

ACCURACY. Stage-discharge relation affected by ice and changed February 23. 

Rating curve used prior to change fairly well defined by several ir easurements 

in previous years, the last of which was on September 30, 1926. Rating curve 

used after change is fairly well defined by seven measurements made during 

current year and ranging from 23 to 5,530 second-feet. Staff gage read to 

half-tenths once daily. Daily discharge ascertained by applying daily gage 

height to rating table except as noted in footnote to table of daily discharge. 

Records fair.

COOPERATION. Records furnished by State engineer of Oregon.

about 10 miles downstream and has a maximum capacity of 2,500 secondfeet. Several smaller canals, total capacity of about 2,900 second-feet^ 

divert below New York Canal. Since February 21, 1915, flow has been 

regulated by storage in Arrowrock Reservoir, 4 miles upstream, which has 

capacity of about 280,000 acre-feet. Water is stored during winter and 

spring and released during irrigation season.
TRIBUTARY BASINS 139

ACCURACY. Stage-discharge relation changed slightly October 1 21, March 19 

to April 11; practically unaffected by ice. Two rating curves, well defined 

below 13,000 second-feet by 18 discharge measurements made during year 

and shape of previous curves, were used; one from October 1 to March 18 

and the other from March 19 to September 30. Operation of water-stage 

recorder satisfactory except for short periods water was below intake pipe. 

Daily discharge ascertained by applying to rating table mean daily gage 

height determined by inspection of recorder graph; shifting-control method 

used October 1-21 and March 19 to April 11. Records good except those 

for estimated periods which are fair.

COOPERATION. Eight discharge measurements furnished by United States 

Bureau of Reclamation and water master for Boise River.

DIVERSIONS FROM BOISE RIVER, IDAHO

Below mouth of Moore Creek and between gaging stations at Dowiing ranch 

and Notus 27 principal canals and a number of small farm laterals divert water 

from Boise River for use in irrigation.

Daily gage-height records were obtained, frequent discharge measurements 

made, and records summarized under direction of W. E. Welsh, water master for 

Boise River.

Records are available from 1919 to 1927. Record of daily diversions subsequent to 1915 is on file in office of Idaho commissioner of reclamation.

ECJUIPMENT. An continuous water-stage recorder on right bank; installed August 

14, 1925. Discharge measurements made from cable 100 feet above gage or 

by wading.

CHANNEL AND CONTKOL. Bed composed of mud and gravel. One channel at 

all stages. Control of coarse gravel and rock; practically permanent.

EXTREMES OF DISCHARGE. Maximum stage during year, from water-stage recorder, 10.1 feet at 2 p. in. May 17 (discharge, 8,440 second-feet); minimum 

stage, 2.23 feet at lip. m. October 7 (discharge, 223 second-feet).

1911-1927: Maximum discharge recorded, 9,200 second-feet at 11 a. m. 

May 15, 1917 (gage height, 9.53 feet); minimum discharge, 142 second-feet 

December 31, 1925 (gage height, 1.92 feet).

DIVERSIONS AND REGULATION. None.
TRIBUTARY BASINS 143

ACCURACY. Stage-discharge relation changed June 10-20; slightly affected by 

ice. Rating curve used prior to June 10 is well defined between 200 and 

6,500 second-feet by five discharge measurements made during current year 

and shape of former curve; curve used subsequent to June 20 ie well defined 

between 400 and 6,000 second-feet by three measurements made during current year arid shape of former curve. Operation of water-stage recorder 

satisfactory except for breaks in record due to inattention of observer. 

Daily discharge ascertained by applying to rating table mean daily gage 

height determined by inspection of recorder graph except June 10-20 during 

which shifting-control method was used. Records good.

head gates at Little Camas Reservoir.

ACCURACY. Stage-discharge relation changed slightly after break in canal 

August 6-17; no flow during winter. Two rating curves fairly well defined 

between 35 and 70 second-feet; by one discharge measurement each and 

shape of curve used in 1926. 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 for August 4, 19, 

20, and September 9, for which discharge is mean of discharge for shorter 

intervals. Records good.

COOPERATION. Gage-height record furnished by Mountain Home Irrigation 

District.

Water released from Little Camas Reservoir in sec. 9, T. 1 S., R. 9 E., is 

carried 13 miles through Little Camas Canal into Long Tom Basin and collected 

in Long Tom Reservoir for release for irrigation use on about 5,000 acres of 

land near Mountain Home.

MOORE CREEK NEAR ARROWROCK, IDAHO

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 3 miles southwest of Arrowrock, 

Boise County.

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

RECORDS AVAILABLE. October 1, 1914, to September 30, 1927 (discharge 

measurements only prior to December 1, 1915).

EQUIPMENT. Vertical staff 011 right bank, 35 feet above highway bridge. Discharge measurements made from 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. One channel at all stages. Control shifts frequently owing to 

deposition of sand at low stages and scouring out at high stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 4.30 feet April 

27 and 7.50 a. m. April 28 (discharge, 2,670 second-feet); minimum stage, 

0.40foot October 1 (discharge, 33 second-feet).

1915-1927: 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.

DIVERSIONS AND REGULATION. No large diversions above station; no regulation.

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

curve well defined below 2,600 second-feet by 20 discharge measurements, 

ranging from 40 to 2,500 second-feet and made during the current year, and 

shape of previous curve. Gage read to hundredths one? 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 29 to 

March 28 and by shifting-control method for remainder of year. Daily 

discharge records fair; monthly records good.

COOPERATION. Eleven discharge measurements furnishec1 by United States 

Bureau of Reclamation and water master for Boise River.

MALHEUR RIVER BELOW WARMSPRINGS RESERVOIR, NEAR RIVERSIDE, OREG.

LOCATION. In SW. % sec. 17, T. 23 S., R. 37 E., 1 mile below Warmsprings Dam.

3 miles above mouth of South Fork, and 4 miles northwest of Riverside,

Malheur County.

DRAINAGE AREA. About 1,100 square miles. 

RECORDS AVAILABLE. December 9, 1914, to July 4, 1917, and March 18, 1919,

to September 30, 1927. From January 3, 1906, to March 31, 1907, and

December 15, 1908, to May 25, 1910, records were obtained at a station at

Riverside 4 miles below.
150 SURFACE WATER SUPPLY, 1927, PART XII B

EQUIPMENT. Hook gage in stilling well on left bank; installed April 19, 1927. 

Prior to April 19 a vertical staff gage at same location wrs used. Discharge 

measurements made from highway bridge one-fourth mfe below dam or by 

wading.

CHANNEL AND CONTROL. New concrete control completed April 19, 200 feet below 

gage. Above a medium stage concrete control is submerged and riffle 200 

feet farther downstream acts as control.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 5.36 feet at 6 

p. m. June 10 (discharge, 855 second-feet); seepage amounted to 1 second-foot 

when gates to reservoir were closed.

1906-1910, 1914-1917, 1919-1927: Maximum discharge recorded, 5,490 

second-feet March 2, 1910; minimum discharge recorded prior to construction of dam, practically no 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.

DIVERSIONS AND REGULATION. A large area of bottom land is irrigated with 

flood water above station. Beginning November, 191P, flow past station 

entirely controlled by operation of gates in Warmsprings Dam.

ACCURACY. Stage-discharge relation changed by new concrete control, completed April 19. Rating curve used before change veil denned below 

1,000 second-feet by six discharge measurements made in 1925 and 1926. 

Rating curve used subsequent to change is well defined between 39 and 765 

second-feet by five discharge measurements made during current year. 

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

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

dailj* gage height or weighted daily gage height to rating table. Records 

good.

CHANNEL AND CONTROL. Bed at wide riffle composed of hardpan, gravel, and 

small boulders; not subject to shift, but stage-discharge relation may be 

affected by aqueous growth. One channel at all stages.

EXTREMES OF DISCHARGE. Maximum discharge during year occurred February 

21 when recorder was not operating; minimum discharge, 3.2 second-feet at 

3 p. m. October 5 (gage height, from water-stage recorder, 0.60 foot).

1913-1923, 1926-1927: Maximum discharge recorded, 8,450 second-feet 

during night of February 7, 1916; minimum discharge, that of October 5, 

1926.

Estimated discharge of flood of March 1, 1910, from high-water mark at 

Froman ranch, 12,600 second-feet. The floods of March 7 and 9, 1894, are 

said to have been about 0.3 foot higher.

DIVERSION AND REGULATION. Many small diversions are made from river and 

its tributaries above gage, the largest being made near Drewsey and from 

North Fork near Juntura. Flow controlled to a large extent since November, 

1929, by Warmsprings Dam.

ACCURACY. Stage-discharge relation affected by aquatic growth on control 

during October, November, and July to September, and by ice during part 

of winter. Rating curve fairly well defined below 1,500 second-feet by 

eight discharge measurements made during year. 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 obtained by inspecting recorder graph; shifting-control method used 

October 1 to November 30 and July 1 to September 29 on basis of discharge 

measurements of October 1, July 7, 28, and September 11. Records good 

except flat estimates of discharge, which are fair.

channel at all stages. Control composed of large boulders; well defined and 

practically 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.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 13.7 feet at 

8.30 and 11 a. m. June 14 (discharge, 22,300 second-feet); minimum stage, 

2.12 feet October 30 (discharge, 655 second-feet).

1922-1927: Maximum stage and discharge recorded, tl at of June 14, 1927; 

minimum discharge recorded, 455 second-feet December 18, 1924.

DIVERSIONS AND REGULATION. Several diversions for irrigation from tributaries 

above station. Spring and summer flow slightly affected by regulation at 

outlet of Payette Lake, 58 miles upstream. Between tl e stations at Banks 

and Horseshoe Bend the river leaves the granite and enters lava formation, 

and a loss occurs which ranges from 2 to nearly 4 per cent of the mean annual 

flow.

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

22-27. Rating curves are well defined; based on discharge measurements 

for 1926 and nine measurements ranging from 841 to 22,000 second-feet and 

made during the current year. Gage read to hundredths once daily. Daily 

discharge ascertained by applying daily gage height to rr.ting table; shiftingcontrol method used February 23 to June 13. Records good.

high water on June 13; slightly affected by ice December 14-18 and January 

22-29. From October 1 to June 13 rating curve used is well defined by 

nine discharge measurements ranging from 655 to 20,200 second-feet and 

made during this period; after June 13 curve used drawn on basis of five 

measurements, ranging from 1,270 to 16,900 second-feet and made after 

high water, and shape of previous curve. Operation of water-stage recorder 

satisfactory. Daily discharge ascertained by applying to rating table mean 

daily gage height determined by inspection of recorder graph; shiftingcontrol method used June 14-21. Records good. 

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

and enters lava formation, and a loss in flow occurs between these stations, as

shown by the records.

ACCURACY. Stage-discharge relation permanent except during period February 

21 to March 15, when tree was lodged on control; not affected by ice because 

of close proximity to lake. Rating curve is well defined below 3,500 secondfeet; based on preceding curve and 16 discharge measurements made during 

1926 and 1927, of which eight measurements, ranging from 105 to 3,380 

second-feet, were made during current year; curve used during period affected 

by tree on control was based on one discharge measurement made March 10. 

Operation of water-stage recorder satisfactory except December 21-29, 

January 1-14, 24-30, and February 6-14. Daily discharge ascertained by 

applying to rating table mean daily gage height determined by inspection 

of recorder graph except as noted above. Records excellent except those for 

estimated periods, which are fair.

CRANE CREEK NEAR MIDVAIE, IDAHO

LOCATION. In SE. J£ sec. 19, T. 12 N., R. 2 W., 400 feet below Crane Creek 

Dam and 12 miles southeast of Midvale, Washington County. No tributaries between dam and station; Last Chance Creek enters three-quarters 

of a mile below station.

DRAINAGE AREA. 269 square miles (measured on topographic maps).

RECORDS AVAILABLE. October 30, 1910, to April 8, 1916; May 1, 1924, to 

September 30, 1927.

EQUIPMENT. Au water-stage recorder on right bank, installed May 2, 1924. 

Discharge measurements made from cable or by wading.

CHANNEL AND CONTROL. Bed composed of lava rocks and coarse gravel, very 

rough. One channel at all stages. Control formed by 20-foot Cippoletti 

weir, installed in concrete 25 feet below gage. Average elevation of weir 

crest corresponds to 0.02 foot on gage.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 3.19 feet February 21-23 (discharge, 596 second-feet); channel reported dry October 9-26, November 17 to February 4, February 9-16, 

May 16-31, June 1, 21, 22, July 14 and 15.

1910-1916, 1924-1927: Maximum stage recorded, 8.9 feet December 3, 

1910 (discharge, 4,240 second-feet); no flow reported at tinier each year 

when gates in dam are closed.

DIVERSIONS AND REGULATION. No large diversions above gage. Flood waters 

are impounded in Crane Creek Reservoir and flow past gage therefore shows 

only the amount of water released through dam and does not necessarily 

represent natural flow of Crane Creek. Flow regulated by gates at dam.

ACCURACY. Stage-discharge relation changed slightly about February 21, owing 

mostly to leakage under artificial control; not affected by ice. Rating 

curves are well defined below and extended above 300 second-feet. Curve 

used October 1 to February 21 is based on discharge measurements made 

in 1926; curve used thereafter is based on shape of preceding curve and 

eight discharge measurements ranging from 9 to 191 second-feet, made during current year. 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 during days of appreciable change in stage for which discharge was determined by averaging 

results obtained by applying to rating table mean gage heights for hourly 

or other intervals of the day and except as indicated in footnote to table 

of daily discharge. Records good.

COOPERATION. Services of observer furnished by Crane Creek Reservoir Administration Board.

WEISER IRRIGATION DISTRICT CANAL NEAR WEISER, IDAHO

LOCATION. In sec. 32, T. 11 N., R. 4 W., at Durbin ranch, 1^ miles below headworks of canal and 7 miles above Weiser, Washington County.

RECORDS AVAILABLE. April 29, 1920, to September 30, 1927.

EQUIPMENT. Friez water-stage recorder adjacent to left sid^ of concrete rating 

flume. Zero of gage is at bottom of rating flume. Discharge measurements 

made from footwalk across concrete rating flume.

CHANNEL AND CONTROL. Bed composed of hard clay and gravel; fairly permanent. 

Banks are clean and not subject to appreciable growth of moss or weeds.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 3.38 feet at noon July 8 (discharge, 21£ second-feet); canal 

practically dry for long periods during winter.

1920-1927: Maximum discharge recorded, 3.43 feet at 9 a. m. May 5, 

1926 (discharge, 219 second-feet); canal usually dry except during irrigation 

season.

DIVERSIONS AND REGULATION. One farm lateral diverts water a quarter of a mile 

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

practically forms head of canal, although actual diversion from Weiser River 

is located about \% miles above gage. Water from waste gate returns to 

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

ACCURACY. Stage-discharge relation not permanent; no flow during winter. 

Three well-defined rating curves used, based on shape of previous curves and 

eight discharge measurements ranging between 119 f,nd 184 second-feet 

and made during the current year. Operation of wate--stage recorder satisfactory. Daily discharge ascertained by applying to rating table mean 

daily gage height determined by inspection of recorder graph; shiftingcontrol method used May 5-6 and July 23-28. Records excellent.

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

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

Weiser River in sec. 3, T. 10. N., R. 4 W., ll/2 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 T^eiser. The district 

maintains about 20 miles of main canal.

SALMON EIVEE BELOW YANKEE FORK, NEAR CLAYTON, IDAHO

191

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 Clay ton, 

Custer County.

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

RECORDS AVAILABLE. October 28, 1921, to September 30, 1927.

EQUIPMENT. Au water-stage recorder on left bank; installed September 3, 1927. 

Prior to this date a vertical staff at present site was used. Gage datum 

lowered 1.50 feet on October 3, 1926. 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 discharge during year (estimated), 8,000 

second-feet June 27, based on flow at Stanley and Salmon (gage height, 

about 9.65 feet); minimum stage recorded, 1.42 feet on mornings of October 

30, 31, February 11 and 12 (discharge, 249 second-feet).

1922-1927: Maximum discharge recorded, that of June 27, 1927; minimum 

stage and discharge recorded, that of October 30, 31, 1926, and February 11 

and 12, 1927.

DIVERSIONS AND REGULATION. No large diversions above station. No regulation because power plant at Sunbeam Dam is not being operated.

ACCURACY. Stage-discharge relation permanent except as affected by ice January 21-25 and February 13-18. Rating curve is well defined between 300 

and 7,000 second-feet, based on shape of preceding curve and eight discharge 

measurements ranging from 333 to 6,230 second-feet and made during 

current year. After September 2 operation of water-stage recorder was 

satisfactory; from October 1 to September 1 staff gage was read to hundredths 

and half-tenths generally twice daily except during period December to 

April when only one reading daily was reported. Daily discharge ascertained by applying daily or mean daily gage height to rating table, except 

as indicated in footnote to table of daily discharge. During period waterstage recorder was operated mean daily gage heights were determined by 

inspection of recorder graph. Records excellent for September; others good 

except those for estimated periods, which are fair.

COOPERATION. Gage-height record furnished by Love & Von Brecht.

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

curve, well defined between 570 and 10,000 second-feet, is based upon preceding curve and eight discharge measurements ranging from 862 to 9,000 

second-feet and made during the current year. Gage read to hundredths 

once daily except during high stages when it was read to half-tenths. Daily 

discharge ascertained by applying daily gage height to rating table except 

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

those for March to April, which are fair.

YANKEE FORK OF SALMON RIVER NEAR CIAYTON, IDAHO

LOCATION. In sec. 20, T. 11 X., 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 map).

RECORDS AVAILABLE. May 3, 1921, to September 30, 1927.

EQUIPMENT. Vertical staff on right bank. Datum of gage lowered 0.50 foot 

October 3, 1926. 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 denned 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 wT hen in flood.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 6.10 feet June 

8 (discharge, 2,420 second-feet); minimum discharge, 14 second-feet at 7.10 

a. m. October 30, November 2, and at 4.10 p. m. December 5 (gage height, 

0.79 foot).

1921-1927: Maximum discharge recorded, 3,360 second-feet at 8 p. m. 

June 12, 1921 (gage height, 6.79 feet present datum); minimum stage and 

discharge recorded, that of October 30, November 2, and Decerrber 5, 1926.

DIVERSIONS AND REGULATION. None.

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

Rating curve well defined between 30 and 2,000 second-feet, is based on 20 

discharge measurements made during 1925 to 1927, of which seven measurements, ranging from 35.1 to 1,780 second-feet, were made during current 

year. Gage read, usually to hundredths twice daily. Daily discharge ascertained by applying daily or mean daily gage height to rating tab1 ^. Records 

good except those for estimated periods, which are fair.

COOPERATION. Gage-height record furnished by Love & Von Bre?ht.

BIG BOULDER CREEK NEAR CIAYTON, IDAHO

LOCATION. In NE. % sec. 15, T. 9 N., R. 17 E., below power plant of 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 plats).

RECORDS AVAILABLE. May 15, 1926, to September 30, 1927.
TRIBUTARY BASINS 199

EQUIPMENT. Vertical staff on left bank 30 feet below tailrace of power plant, 

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 year, 2.04 feet 

morning of June 26 (discharge, 206 second-feet); minimum estimated discharge, 6 second-feet, January 1 to February 19.

1926-1927: Maximum stage and discharge occurred on Jun^ 26, 1927; 

minimum measured discharge, 5.9 second-feet, September 23, 1926.

DIVERSIONS AND REGULATION. 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; flow past gage practically unaffected 

by power diversion above.

ACCURACY. Stage-discharge relation changed May 14-17 and on June 26; not 

seriously affected by ice. Three rating curves fairly well defined by 15 

discharge measurements, of which 11 made during the current year were 

used October 1 to May 13, May 18 to June 25, and June 27 tc September 

30, respectively. Gage read to hundredths twice daily except lecember 12 

to February 19, when gage was not read. Daily discharge determined by 

applying mean daily gage height to rating table, except for period of missing 

gage heights, for which it was estimated, based on power plant operator's 

report of flow through power plant; shifting-control method used May 

14-17 and June 26. Records fair except those for November 16 to May 13, 

which are poor owing to missing and unreliable gage heights.

COOPERATION. Gage-height record furnished by Livingston Mines Corporation.

Daily discharge, in second-feet, of Big Boulder Creek near Claylon, Idaho, for the 

year ending September 30, 1927

EXTREMES OF DISCHARGE. Maximum stage during year, determined from highwater marks in gage well, 5.1 feet about June 8 (discharge, determined from 

extension of rating curve about 2,950 second-feet); minimum stage, 1.22 feet 

at 4-9 a. m. October 2 (discharge, 76 second-feet).

1921-1927: Maximum stage and discharge recorded, that of June 8, 1927; 

minimum stage recorded, 1.03 feet August 1, 2, 5, and 6, 1926 (discharge, 

44 second-feet). Lower discharge probably occurred during period of no 

record.

DIVERSIONS AND REGULATION. None.

ACCURACY. Stage-discharge relation permanent except as affected by ice; 

observations discontinued during winter. Rating curve based on eight 

discharge measurements, five of which were made during current year, and 

preceding curves well defined between 60 and 1,800 second-feet, above 

which it is extended. Operation of water-stage recorder satisfactory except 

June 8-18, when discharge was estimated by comparison with flow of Deadwood River and from high-water mark occurring June 8. Daily discharge 

ascertained by applying to rating table mean daily gage height determined 

from inspection of recorder graph except as noted above. Records good 

below 1,800 second-feet; others fair.

EAST FORK OF WALLOWA 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.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. July 27, 1924, to September 30, 1927.

^EQUIPMENT. Vertical staff on right bank, 100 yards above bridge on road to 

power house. 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. Fed 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, 2.20 feet at 

1 p. m. June 26 (discharge, 203 second-feet); minimum stag3, 0.62 foot 

at 1 p. m. January 31 and February 15 (discharge, 0.5 second-foot).

1924-1927: Maximum and minimum discharges recorded, those of June 26, 

January 31, and February 15, 1927.

DIVERSIONS AND REGULATION. The penstock to Wallowa Falls power house 

diverts at dam 1 mile upstream. 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 affected by ice and changed June 8. Rating 

curve used October 1 to June 7 well defined below 100 second-feet by 12 

discharge measurements, of which 4 were made during current year. 

Rating curve used June 8 to September 30, well defined below 7C second-feet 

by four discharge measurements made during current year; extended above. 

Staff gage read to hundredths twice daily except during winter and occasionally at other times when it was read once daily. Daily discharge ascertained 

by applying daily or mean daily gage height to rating table. Pecords fair.

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. They indicate that inflow between dam and gaging station is 2 to 3 secondfeet at low water and averages 17 per cent of flow at gaging station vhen flow at 

station is more than 15 second-feet.

WALLOWA FALLS POWER PLANT TAILEACE NEAR JOSEPF, OREG.

LOCATION. In SE. % sec. 29, T. 3 S., R. 45 E., 150 feet below power house, a 

quarter of a mile above point where channel discharges into the West Fork 

of Wallowa River, and 6 miles above Joseph, Wallowa County.

RECORDS AVAILABLE. August 27, 1924, to September, 30, 1927.

EQUIPMENT. Vertical staff on right wing wall of weir 150 feet below power 

house. Discharge measurements made by wading or from plank.

CHANNEL AND CONTROL. The control is a 5-foot Cippoletti weir made from 2-inch 

plank, beveled at top and set in concrete. The weir vas bent 20 degrees 

out of plumb on June 27 by overflow from East Fork of Wallowa River.
TRIBUTARY BASINS 209

EXTREMES OF DISCHARGE. Maximum discharge through power plant recorded 

during year, 11 second-feet August 24 (gage height, 0.68 foot); minimum 

discharge recorded, 4.5 second-feet at 6 a. m. several days in April and May 

(gage height, 0.44 foot).

1924-1927: Maximum discharge recorded that of August 24, 1927; 

minimum discharge recorded, 3.5 second-feet August 31 and September 1, 

1924 (gage height, 0.34 foot).

DIVERSIONS AND REGULATION. Flow regulated by discharge through nozzle for 

impulse wheel in power house, but opening in nozzle is changed only about 

twice a day, minor variations in load being taken care of by deflection of 

nozzle.

ACCURACY. Stage-discharge relation changed June 27 when weir was bent partly 

over by overflow from East Fork of Wallowa River. Rating curve used 

prior to change is fairly well defined by three discharge measurements made 

during year; rating curve used after, defined by only one discharge measurement made on July 24 and former well-defined curve. Staff gage generally 

read to hundredths twice daily but occasionally read only once ds.ily. Daily 

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

table; but when ga^e was not read or read only in morning, discharge was 

estimated. Records fair.

Water is diverted at dam on East Fork of Wallowa River into a conduit 16 or 

18 inches in diameter and carried 1 mile to power house. After leaving power 

house the water follows a tortuous channel for a quarter of a mile and discharges 

into West Fork. Elevation of crest dam above nozzle at power house is 1,160 

feet.

76,600 second-feet); minimum stage occurred in December, 1919, when 

stage-discharge relation was affected by ice (discharge probably less than 

500 second-feet).

DIVERSIONS AND REGULATION. Several small ditches divert water for irrigation 

above station. No regulation.

ACCURACY. Stage-discharge relation probably changed slightly on December 4; 

not affected by ice. Rating curve used prior to change is well denned below 

60,000 second-feet, above which it is extended; subsequent to December 3- 

a curve was used based on shape of previous curve and five discharge measurements made during current year and ranging from 3,680 to 52,400 

second-feet. Gage read to tenths once daily. Daily discharge determined, 

by applying daily gage height to rating table. Records good.

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

CLEARWATER RIVER NEAR LEWISTON, 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, 1927, when station was discontinued.

DRAINAGE AREA. 9,640 square miles.

EQUIPMENT. Stevens continuous water-stage recorder on right bank at former 

Central Ferry site; installed October 2, 1924. Zero of present gage is at 

733.33 feet above mean sea level when referred to United States Geological 

Survey bench marks at Lewiston as described in Bulletin 567. Discharge 

measurements made from highway bridge at Lewiston and at Spalding and 

from cable 8 miles upstream at Spalding. 

HANNEL AND CONTROL. Bed composed of boulders and gravel. Two channels 

at extremely high stages. Control formed by well-defined gravel and 

boulder riffle; not permanent.

TREMES OF DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 18.26 feet at 1 p. m. June 9 (discharge, 109,000 second-feet); 

minimum stage recorded, 3.46 feet at 2 to 7 p. m. August 29 (discharge, 

3,340 second-feet).

1910-1913, 1924-1927: Maximum stage and discharge recorded on June 

9, 1927; minimum stage, 2.4 feet August 14 and 16, 1926 (discharge, 2,030 

second-feet).

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.

DIVERSIONS AND REGULATION. None.

\
218 SURFACE WATER SUPPLY, 1927, PART XII B

ACCURACY. Stage-discharge relation changed April 29, 30, and May 19, durin 

flood stages; not affected by ice. Rating curve used October 1 to April 2 

well defined between 2,000 and 50,000 second-feet and extended above 

checked closely by four discharge measurements made during this perioc 

Two curves used thereafter based on 11 additional measurements mad 

during current year ranging in discharge from 4,610 to 107,000 second-feet 

Operation of water-stage recorder not entirely satisfactory. Daily discharg 

ascertained by applying to rating table mean daily gage height determineby inspection of recorder graph except as indicated in footnote to table o 

daily discharge. Records excellent.

COOPERATION. Gage-height record furnished by Inland Power & Light Co.

Daily discharge, in second-feet, of Clearwater River near Lewiston, Idaho, for th 

year ending September 80, 1927

TFCANNON RIVER NEAR POMEROY, WASH.

LOCATION. In sec. 13, T. 11 N., R. 40 E., at highway bridge at abandoned post 

office of Marengo, 9 miles southwest of Pomeroy, Columbia County, 14 

miles above Petaha Creek, and 17}£ miles north of Dayton.

DRAINAGE AREA. 109 square miles (measured on Umatilla National Forest 

map).

RECORDS AVAILABLE. August 31, 1913, to June 30, 1915; March 1, 1924, to 

September 30, 1927.

EQUIPMENT. Vertical staff in two sections on downstream corner of left abutment. Discharge measurements made from highway bridge or by wading.

CHANNEL AND CONTROL. Bed composed of gravel. Banks not subject to overflow. Control formed by boulder and gravel riffle 75 feet below gage; 

shifting at high water.

EXTREMES OF DISCHARGE. Maximum discharge recorded during year, 602 

second-feet April 28 (gage height, 5.38 feet); minimum stage, 4.15 feet 

October 1 (discharge, 59 second-feet).

1913-1915, 1924-1927: Maximum discharge, 642 second-feet at 8.30 a. m. 

February 5, 1925 (gage height, 5.35 feet); minimum stage recorded, 1.2 feet 

at 7.30 a. m. December 24. 1914 (discharge, 25 second-feet).

DIVERSION AND REGULATION. Several small diversions for irrigation above 

station.

ACCURACY. Stage-discharge relation changed on April 29 and gradually thereafter until June 30; affected by ice December 14-17 and January 18-26. 

Rating curve used October 1 to April 28, well defined below 400 second-feet; 

checked by two discharge measurements made in April of current year. 

Curve used July 1 to end of year fairly well denned by ore discharge measurement, point of zero now, and shape of previous curves. Gage read to 

hundredths once daily. Daily discharge ascertained by applying daily 

gage height to rating table; shifting-control method, based upon results 

of three discharge measurements made during the period, used April 29 to 

June 30. Records good.
