ATTTHOBIZATION 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 years ending September 30, 1919 and 1920.

The data presented in these reports were collected by the United 

States Geological Survey under the following authority contained 

in the organic law (20 Stat. L., p. 394) :

Provided, That this officer [the Director] shall have the direction of the Geological 

Survey and the classification of public lands and examination of the geological structure, mineral resources, and products of the national domain.

The work was begun in 1888 in connection with special studies 

relating to irrigation in the arid West. Since the fiscal year ending 

June 30, 1895, successive sundry civil bills passed by Congress have 

carried the following item and appropriations:

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

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

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

Annual appropriations for the fiscal years ending June SO, 1895-1921.

In the execution of the work many private and State organizations have cooperated, either by furnishing data or by assisting in 

eolleetmg data. Acknowledgments for cooperation of the first kind 

are made in connection with the description of each station affected; 

cooperation of the second kind is acknowledged on page 9.

Measurements of stream flow have been made at about 5,000 

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

the Hawaiian Islands. In July, 1920, 1,350 gaging stations were 

being maintained by the Survey and the cooperating organizations. 

Many miscellaneous discharge measurements are made at other 

points. In connection with this work data were also colieettd 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«off" or "discharge" is expressed in various terms, each of which has become 

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

into two groups (1) those that represent a rate of flow, as secondfeet, gallons per minute, miners' 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 niches, 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 tihe quantity 

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

The following terms not in common use are here defined:

"Stage-discharge relation"; an abbreviation for the term **f&lation 

of gage height to discharge." .

"Control"; a term used to designate the natural section or stretch 

of the channel or artificial structure below the gage which dafcenaines 

tibe 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 poiBt on 

l&e gage the gage height at which water ceases to flaw overthe 

control.

EXPLANATION #F DATA.

The datia pf«s«rt»d in $kis report cowr the two-year period b«giafiing October 1, 1918, and ending September 30, 19i§. At tlfee %egfflnkig of January in most parts of the United States rauefe. of the pre*- 

eipitation in the preceding three months is stored as ground water, in 

the form of snow or ice, or in ponds, lakes, and swamps, «nd this 

stored water passes off in the streams during the spring break-up. At 

tbe end of September, on the other hand, the only stored water avail- 

«Me for nm-off is possibly a small quantity in tfee ground; therefore 

tfae rim-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 used to 

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

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

that gives a continuous record of the fluctuations. Measurements of 

discharge are made with a current meter, (See Pis. I, IL) The 

.general methods are outlined in standard textbooks on the measurement of river discharge.

From the discharge measurements rating tables *re prepared that 

give the discharge for any stage, and these rating tables, when applied to gage heights, give the discharge from which the daily, 

»a$nthly, and yearly means of discharge are determined.

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

Hiis report comprise a description of the station, fi table giving 

results of discharge measurements, a table showing the daily discharge 

 el 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 

«tre published.

The description of the station gives, in addition to statements 

regarding location and equipment, information in regard td any eottditions that may affect the permanence of the stage-discharge relation, covering such subjects as the occurrence of ice, tfee 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 

fbw «,t the gage, artificial regulation, maximum and minmi'ttra recorded stages, and the accuracy of the records.

The taMe of daily discharge -gives, in general, the o!ischarge in 

fieoond-leet eoteasponding to the mean of the gage heigtdss read each

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

mean daily discharge may be. obtained by averaging quantities of 

discharge for regular intervals during the day, or by means of a 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 aot 

indicate correctly the stage when the water surface was at crest 

height, and the corresponding discharge was consequently larger 

than given in the maximum column. Likewise, in the column 

headed "Minimum" the quantity given is the mean flow for the 

day when the mean gage height was lowest. The column headed 

"Mean" is the average flow in cubic feet per second during the 

month. On this average flow computations recorded in the remaining columns, which are defined on page 2, are based.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS.

The accuracy of stream-flow data depends primarily (1) on the 

permanence of the stage-discharge relation and (2) on the accuracy 

of observation of stage, measurement 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 cen|* 

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

individual measurements with reference to the mean rating curve.

The monthly means for any station may represent with high accuracy the quantity of water flowing past the gage, but the figures 

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

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

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

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

the river above the station. "Second-feet per square mile'* and 

"run-off in inches" are-therefore not computed if such errors appear 

probable. The computations are also omitted for stations on streams 

draining areas in which the annual rainfall is less than 20 inches. All
figures representing "second-feet per square mile" and "run-off in 

inches" previously published by the Survey should be used with 

caution because of possible Inherent sources of error not known to the 

Survey,

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 below the 

station 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.

PtJBLICATIONS.

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.

The results of stream-flow measurements are now published 

annually in 12 parts, each part covering an area whose boundaries, 

coincide with natural drainage features as indicated below:

PART I. North Atlantic slope basins.

II. South Atlantic slope and eastern Gulf of Mexico basins.

III. Ohio Biver basin.

The records at most of the stations discussed in these reports 

extend over a series of years, and miscellaneous measurements at 

many points other than regular gaging stations have been mada 

each year. An index of the reports containing records obtained 

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

The following table gives, by years and drainage basin, the numbers of papers on surface-water supply published from I89& to 1920, 

The data for any particular station will be found in the reports 

covering, the years during which the station was maintained. For 

example, data for 1902 to 1920 for any station in the arm covered 

by Part IK are published hi Water-Supply Papers 83, 98, 128, 169, 

205, 243, 263, 283, 303, 323, 353, 383, 403, 433, 453, 473, and 503, 

which contain records for the Ohio River basin for those years. 

Results of miscellaneous measurements are published by drainage

GAGING-STATION RECORDS.

SNAKE RIVER.

SNAKE RIVER AT SOUTH BOUNDARY OS* YELLOWSTOBTE NATIONAL PARK.

LOCATION. A quarter of a mile below junction of Lewis and Snake rivers, half a mite 

north of Snake River soldier station and south boundary of Yellowstone National 

Pack, and 25 miles north of Moran, Wyo.

DRAINAGE AREA. 490 square mijea (measured on topographic maps). ;

EECOEDS AVAILABLE. June 19,1913, to September 30,1920.

GAGE. Overhanging chain gage on right bank; read by J.W. Eline and W. N. Ptmlue. 

Auxiliary chain gage on bridge about 2| miles downstream used August 4 to 

September 2 and September 4-14,1918, and July 25 to September 1 and September 3 and 4, 1920; read by Ed Shield.

DISCHARGE MEASUBEMENTS. Made from cable 225 feet below gage or by wading*

CHANNEL AND CONTROL. Bed composed of coarse gravel; clean except for occasional 

lodgment of drift. Control probably permanent at ordinary stages. One channel at gage but divided by an island into two channels at control.

EXTREMES OP DISCHARGE. Maximum stage recorded during yea* ending September 

30,1919, 5.9 feet at 7 p. m.-May 22 (discharge, 4,320 second-feet); minimum .stage, 

1.8 feet August 24-30 (discharge, 185 seconds-feet).

Maximum stage recorded during year ending September 30, 1920, 6.3 feet at 

6 p% m. June 13 (discharge, 5,100 second-feet); minimum stage, 1.8 feet October 29 

and 30, January 18-20, and February 20 and 21 (discharge, 185 aecond-feet)* » 

1913-1920: Maximum discharge during period, 5,690 second-feet June*?, 1$J4 

(gage height, 6.3 feet); same stage but lower discharge occurred June 13,1920. 

Minimum stage recorded, 1.4 feet October 26-31, 1915 (discharge, 160 secondfeet).

ICB. Stage-discharge relation not affected by ice, the formation of which is evidently 

prevented by hot springs above gage.

DIVERSIONS. None above station.

REGULATION. None.
SNAKE RIVER BASIN. 11

ACCUEACY. Stage-iiBcbaage relation changed slightly following the high water of 

May, 1919, and again after the high water of June, 1920. Two fairly well defined 

rating curves used, one applicable October 12, 1918, to May 26, 1919, and the 

other June 4, 1919, to July 24, 1920; rating curve for auxiliary gage used July 25 

to September 4, 1920, except for September 2 for which the result of a discharge 

measurement was used. Gage read to half-tenths twice daily during 1919, and 

once daily during 1920, except during periods indicated in footnote to tables 

of daily discharge and except from August 25 to September 4, 1920, when auxiliary gage was read. Daily discharge for days on which gage was read, ascertained 

by applying mean daily or daily gage height to rating table; for periods during 

which gage was not read it was ascertained by interpolation or estimation. Records good October 26,1919, to July 24,1920; others fair.

COOPEEATION. Gage-height record furnished by superintendent of Yellowstone Pack 

and by United States Reclamation Service.

SNAKE RIVER NEAR MORAN, WYO.

LOCATION. In sec. 17, T. 45 N., R. 114 W., 1£ miles below Moran post office, Teton 

County, and United States Reclamation Service dam at outlet of Jackson Lake. 

No important tributaries between dam and station.

DRAINAGE AREA. 820 square miles.

RECORDS AVAILABLE. September 21,1903, to September 30,1920.

GAGE. Combination inclined and vertical staff on left bank; datum lowered 1.0 foot 

July 26, 1915; used continuously until June 22, 1917. Thereafter until June 2®, 

1920, a Stevens 8-day water-stage recorder, installed June 14,1917, on bank in reaf 

of staff gage was used, except during periods October 16, 1917, to May 12, 1918; 

November 10,1918, to May 25,1919, and October 28, 1919, to June 20,1920, during 

which the staff gage was used. From June 21 to September 30, 1920, a Friez 

water-stage recorder at same site as the Stevens recorder was used; staff gage used 

September 21-30, 1920. Observer, Joseph Markham.

DISCHARGE MEASUREMENTS. Made from cable about 100 feet below gage or by wading.

CHANNEL AND CONTROL. Bed composed of gravel and boulders. Control practically 

permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 9.15 feet at 5 a. m. June 16 (discharge, 11,700 second-feet); minimum 

stage, 0.46 foot at 9 a. m. October 5 and 13 (discharge, 23 second-feet.)

Maximum stage recorded during year ending September 30, 1920, 9.02 feet at 

5.45 p. m. July 26 (discharge, 11,000 second-feet); minimum discharge, 13 secondfeet October 26 to December 20 and September 19-22, 29, and 30.

1903-1920: Maximum stage recorded, 10.41 feet at 8 p. m. June 12, 1918 (discharge, 15,100 second-feet); practically no flow during a few days in 1907 and 1909 

as a result of closing of gates in Jackson Lake dam.

ICE. Stage-discharge relation affected by ice. Gates in dam at Jackson'Lake are 

closed during winter. Flow past gage represents leakage through dam and inflow 

from springs.

DIVERSIONS. None between dam and station and none of consequence above Jackson Lake.

REGULATION. Flow controlled by operation of gates in Jackson Lake dam. Storage 

capacity of reservoir, 847,000 acre-feet.

ACCURACY. Stage-discharge relation changed during the high water of June, 1919, 

and again during the winter of 1919-20; affected by ice December 23, 1918, to 

March 31, 1919, and January 18 to April 17, 1920. Rating curve used October 1, 

1918, to June 14, 1919, well defined; curve used June 17, 1919, to April 17, 1920, 

well defined between 500 and 1,500 second-feet and poorly defined outside those 

limits; curve used April 18 to September 30, 1920, well defined; shifting-control 

method used June 15 and 16,1919. Operation of water-stage recorder satisfactory 

during periods October 1 to November 9, 1918, May 26 to October 27, 1919, and 

June 21 to September 30, 1920; staff gage read to hundredths once daily duringintervening periods. Daily discharge ascertained by applying to rating table thedaily gage height from staff gage or the mean daily gage height obtained by inspection of recorder graph except for period for which the shifting-control method was 

used, and except for periods during which stage-discharge relation was affected byice for which it was estimated. Records poor June 15 to August 6,1919;fairOctober 

1,1919, to April 17,1920; good for other periods.

COOPERATION. Gage-height record and several discharge measurements furnished 

by United States Reclamation Service.

SNAKE RTVEE HEAR HEISE, IDAHO.

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

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

formerly maintained near Lyon. Several small creeks enter between oldjsite 

and present station.*

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. September 25, 1910, to September 30, 1920.

GAGE. Friez water-stage recorder on left bank; installed July 8, 1913, and referred to 

combined vertical and inclined staff gage, which was used prior to that date. 

Gage inspected by W. J. Kreoaer and Lena Byington.

DISCHARGE MEASUREMENTS. Made from cable about 300 feet below gage.

CHANNEL AND CONTROL. Bed composed of rock ledge, coarse gravel, and cobblestones. One channel at all stages. Control formed by Anderson dam, parts of 

which washed out during high-water periods of 1917 and 1918.

EXTREMES OB DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 4.29 feet at^S p.m. June 16 (discharge, 17,900 second-feet); minimum 

stage, 0.10 foot September 25 and 27 (discharge, 2,670 second-feet). 

Maximum stage recorded during year ending September 30, 1920, 5.7 feet at 

a.xn. June 10 (discharge, 26,000 second-feet); minimum stage, 0.32 foot at 

3 p.m. November 23 (discharge, 2,280 second-feet).

1910-1920: Maximum discharge, about 52,000 second-feet June 16, 1918; minimum discharge, 2,180 second-feet March 10, 1915.

/CE. Stage^discharge relation seriously affected by ice. Observations discontinued 

during winter.

DIVERSIONS. No large diversions above station. A small ditch of about 25 secondfeet capacity takes out just above station.
18 -B.

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

ACCURACY. Stage-discharge relation changed slightly for low stages during winter of 

1918-19. Two well-defined rating curves used, one applicable October 1-8,1918, 

and the other applicable for remaining periods of record. Operation of waterstage recorder fairly satisfactory. Daily discharge ascertained by applying to 

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

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

DIVERSIONS FBOM Sif AKE RIVER BETWEEN HEISE AND SHELLEY GAGING STATIONS ,

IDAHO.

Between Heise and Shelley gaging stations forty-four 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 headgates. Gag-
20 SURFACE WATER SUPPLY, 191&-1920, PABT XH B.

ing 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 for the period June 1,1919, to September 15,1920.

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

and by operation of check gates. Rating curves well defined. Gages read to hundred ths daily. Records considered excellent. 1

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

Heise and Shelley gaging stations, for the irrigation seasons of 1919 and 19t0.

SNAKE BI7EB BASIN.

BRAKE BIVER NEAR SHELLS?. IDAHO.

LOCATION. In sec. 17, T.-l N., R. 37 E., a quarter of a mile aboye Woodville highway 

bridge and 3 miles north of Shelley, Bingham County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. March 18, 1915, to September 30,1920,

GAGE. Friez water-stage recorder on right bank; standard hook gage in float well, 

and combination vertical and inclined staff gage outside. Observers, James 

Thorne, W. F. Dawson, George Davis, and L. P. Dawson.

DISCHARGE MEASUREMENTS. Made from cable 600 feet above gage or by wading.

CHANNEL AND CONTROL. Control formed by lava-rock reef extending across channel, 

about 500 feet below gage. Banks high and clean at gage and control.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending Septembe* 

30, 1919, 9.13 feet May 31 (discharge, 13,700 second-feet); minimum stage, 3.68 

feet at 9.15ti. m. August 29 (discharge, 702 second-feet).

Maximum stage.recorded during year ending September 30,1920,11.59 feet at 2 

a. m. May 20 (discharge, 23,500 second-feet); minimum stage, 4.57 feet at 6 a. m. 

October 1 (discharge, 1,270 second-feet).

1915-1920: Maximum stage recorded, 16.97 feet at 1.30 p. m. June 17,1918 (dis. 

charge, 47,200 second-feet); minimum stage, 3.68 feet at 9.15 a. m. August 29,1919 

(discharge, 702 second-feet).

ICE. Stage-discharge relation probably seriously affected by ice. Observations discontinued during winter.

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

REGTJLATION. Natural flow during irrigation season is augmented by release of stored 

flood waters in Jackson Lake for use on Minidoka project and Twin Falls tracts.

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

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

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

inspection of recorder graph except as indicated in footnote to daily discharge 

table. Records good to excellent.

DIVERSIONS FROM SNAKE RIVER BETWEEN SHELLEY AND PORTERVILLE GAGING

STATIONS, IDAHO.

Between Shelley and Porterville gaging stations nine separate canals divert water 

'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 for the 

period June 1, 1919, to September 15, 1920.

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

plants and by operation of check gates. Rating curves well denned. Gages read 

to hundredths daily. Records excellent.

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

Shelley and Porterville gaffing stations for the irrigation seasons of 1919 and 1920.

SNAKE RIVER AT PORTERVILLE BRIDGE, NEAR BLACKFOOT, IDAHO.

LOCATION. In sec. 26, T. 2 S., R. 35 E., 3$ miles north of Blackfoot, Bingham County,- 

a quarter of a mile below Porterville Bridge, and just below heading of Danskin 

canal. Station was formerly maintained at Porterville Bridge, above heading of 

Danskin canal.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 13, 1918, to September 30, 1920, at present site; June 12 

to September 30, 1916, at site at Porterville Bridge.

GAGE. Friez water-stage recorder on left bank, referred to hook gage inside well and 

vertical staff outside; installed October 27, 1918, at site of inclined gage, which 

had been used since May 13,1918, but at a datum 1.54 feet higher. An auxiliary 

low-water gage on left bank about 100 yards upstream is used during extremely 

low stages. Gage used prior to September 30,1916, vertical staff on right abutment of Porterville Bridge.

DISCHARGE MEASUREMENTS,. Made from cables over two channels about a quarter 

of a mile below gage or by wading.

CHANNEL AND CONTROL. Bed composed of cobble in gravel drift; clean except for 

occasional lodgment of drift. Control may shift at high stages. One channel at 

gage but divided by an island into two channels at control, except at low stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 6.75 feet at 1 p. m. May 1 (discharge, 12,500 second-feet); minimum 

stage from auxiliary low-water gage, 2.07 feet at 9 a. m. September 16 (discharge, 

30 second-feet). ;

Maximum stage recorded during year ending September 30,1920, about 8.3 feet 

May 19 (discharge, 21,600 second-feet); minimum stage, 2.90 feet at 2 p. m. September 23 (discharge, 505 second-feet).

1916; 1918-1920: Maximum stage from inclined gage, 13.5 feet June 17 and 

18, 1918 (discharge, 46,900 second-feet); minimum stage from auxiliary lowwater gage, 2.07 feet at 9 a. m. September 16, 1919 (discharge, 30 second-feet).

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

during winter.

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

station.

REGULATION. Natural flow during irrigation season is augmented by release of stored 

flood waters in Jackson Lake for use on the Minidoka and Twin Falls tracts.
SJTAKE RIVEE BASES'.

AccuRAcr.-^tage-diecharge relation practically permanent during 191&; considered 

to have changed several times during 1920. Rating curve used during 1919, fairly 

well defined. Standard curve used during 1920, well defined below 15,000 

second-feet; extended above that point and subject to error; was used direct 

October 1 to November 25, April 6 to May 13, and August 29 to September 30; 

indirect method for shifting-control used for intervening periods. Operation of 

water-stage recorder rather unsatisfactory; staff gage readings usually obtained 

when recorder was not operating. Daily discharge ascertained by applying to 

rating tabie mean daily gage height from staff gage or mean daily gage height 

obtained by inspection of recorder graph, except for periods for which shiftingcontrol method was used and except as indicated in footnote to daily discharge 

tables. Records fair for 1919; good for 1920.

DIVERSIONS FROM SNAKE RIVER BETWEEN PORTERVILLE AND BLACKFOOT GAGING

STATIONS, IDAHO.

Between Porterville and Blackfoot gaging stations five separate canals divert water 

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
SHAKE KIVER BASIN.

Reclamation to facilitate distribution of the water. Records are available for the 

period June 1, 1919, to September 15, 1920. * 

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

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

hundredths daily. Records considered good.

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

Porterville and Blackfoot gaging stations for the irrigation seasons of 1919 and 1920.

2-8 SURFACE WATER SUPPLY, 1910-1920, PART XII B.

SNAKE RIVER NEAR BLACKFOOT, IDAHO.

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

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

only large tributary between station and mouth of Henrys Fork, 60 miles above. 

Portneuf and Bannock rivers and 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, 1920.

GAGE. Friez water-stage recorder on right bank; installed July 6, 1913, at same site 

and datum as staff gage installed October 1, 1912. Original gage, used June 6, 

1910, to September 30, 1912, was 50 feet above present site. Datum of gage 

raised 0.06 foot June 25, 1911, and 0.03 foot October 1, 1912, when new staff was 

installed. Observer, J. A. dough.

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

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

low and medium stages. Control shifts during high water.

EXTREMES OF DISCHARGE. Maximum stage during year ending September 30, 1919, 

from water-stage recorder, 8.25 feet at 12.30 p. m. May 1 (discharge, 12,100 secondfeet); minimum stage, 1.93 feet at 6 p. m. August 25 (discharge, 118 second-feet). 

x Maximum stage during year ending September 30, 1920, .from water stage 

recorder, 10.15 feet at noon May 20 (discharge, 21,700 second-feet); minimum 

stage, 2.31 feet October 1 (discharge, about 266 second-feet).

1910-1920: Maximum stage during period, from water-stage recorder, 14.8 

feet (approximately) at 5 p. m. June 18, 1918 (discharge, about 46,200 secondfeet); exact discharge uncertain because of probable shift in stage-discharge 

relation at about that time. Minimum stage, 1.93 feet at 6 p. m. August 25, 191& 

(discharge, 118 second-feet).

ICE. Floating ice sometimes present for short periods; stage-discharge relation apparently not affected.

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

station.

REGULATION. Flow regulated by storage in Jackson Lake reservoir and in BlackfootMarsh reservoir on Blackfoot River. Practically entire summer flow is released 

water from these reservoirs.

ACCURACY. Stage-discharge relation changed June 29, 1920. Rating curves well 

defined between 500 and 10,000 second-feet; poorly defined above 10,000 secondfeet. Operation of water-stage recorder satisfactory except during periods indicated in footnote to daily-discharge table. Daily discharge ascertained by applying to rating table mean daily gage height obtained by inspection of recorder 

graph except as indicated in footnote to daily-discharge table. Records excellent except those for extremely low stages and for high stages, which are fair.

SNAKE RIVER AT NEELEY, IDAHO.

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

County, 4 miles southwest of American Falls, and 32 miles above Minidoka dam. 

Portneuf and Bannock rivers and 2,500 second-feet of spring water enter Snake 

River between this station and station near Blackfoot. Baft River enters 18 

miles below Neeley.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. March 17, 1906, to September 30, 1920.

GAGE. Friez water-stage recorder on left bank; installed August 8, 1910, at same 

site and datum as staff gage previously used. Observers, C. Morgan and H. R. 

Wallis.

DISCHARGE MEASUREMENTS. Made from cable at gage.

CHANNEL AND CONTROL. Bed of river at measuring section rough, especially near 

right bank. Banks high and clean. One channel at all stages. Control compdsed of lava rock, probably partly overlain with coarse gravel; shifts slightly.

EXTREMES OF DISCHARGE. Maximum stage during year ending September 30, 1919, 

occurred during period of no record; maximum mean daily discharge, estimated 14,900 second-feet May 2. Minimum stage, from water-stage recorder, 

3.78 feet at 8 a. m. August 31 (discharge, 2,290 second-feet).

Maximum stage during year ending September 30, 1920, from water-stage 

recorder, 9.56 feet at 8 p. m. May 21 (discharge, 25,000 second-feet); minimum 

stage, 3.92 feet at 8 a. m. October 1 (discharge, 2,580 second-feet).

,1906-1920: Actual maximum stage doubtful; maximum mean daily stage, 

13.5 feet June 20, 1918 (discharge, 48,400 second-feet). Minimum stage, 3.65 

feet August 20-22, 1906 (discharge, 2,220 second-feet).
SNAKE RIVER BASIF.

ICB. Stage-discharge relation seriously affected by ice at times.

DIVERSIONS. Numerous canals near Blackfoot and Idaho Falls divert practically 

entire natural summer flow of river.

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

on Minidoka project and Twin Falls tracts. Diurnal fluctuations sometimes 

result from operation of power plant 4 miles upstream.

ACCURACY. Stage-discharge relation changed slightly during winter of 1918-19; 

affected by ice in January, 1919, and during period November 27,1919, to January 

20, 1920. Rating curve used October 1, 1918, to January 5, 1919, well defined. 

Curve used January 6, 1919, to September 30, 1920, well defined below 11,000 

second-feet; extended above that point. Operation of water-stage recorder 

unsatisfactory prior to May 25,1919; thereafter satisfactory except during winter; 

staff gage read about twice weekly during periods of no record from recorder. 

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

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

of daily discharge. Open-water records fair prior to May 25 and good thereafter; 

winter records fair.

corder installed in 1915; inspected by employees of United States Reclamation 

Service.

DISCHARGE MEASUREMENTS. Made from cable 50 feet below gage.

CHANNEL AND CONTROL. Bed composed of coarse gravel. One channel at all stages. 

Control shifts slightly.

EXTREMES OF DISCHARGE. Maximum stage during year ending September 30, 1919, 

from water-stage recorder, 9.33 feet at 11 p. m. May 2 (discharge, 14,200 secondfeet); minimum stage, 4.07 feet at 4.30 p. m. August 2 (discharge, 1,310 secondfeet).

Maximum stage during year ending September 30, 1920, from water-stage recorder, 11.06 feet at 3 a. m. May 22 (discharge, 22,200 second-feet); minimum stage, 

4.15 feet at 5 a. m. October 17 (discharge, 1,380 second-feet).

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

ACCURACY. Stage-discharge relation changed slightly during winter of 1919-20; 

affected by ice November 26,1919, to January 25,1920. Two well-defined rating 

curves used, one applicable October 1, 1918, to January 25, 1920, and the other 

applicable January 26 to September 30, 1920. Operation of water-stage recorder 

satisfactory, except during period December 25,1919, to January 17,1920, when 

staff gage was read to hundredth^ once daily. Daily discharge ascertained by 

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

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

of daily discharge. Open-water records for 1919, excellent; for 1920. good; winter

SNAKE RIVER BASIN. 3$ 

SNAKE RIVER AT MILKER, IDAHO.

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

Twin Falls County. No tributaries enter Snake 'River between Minidoka station and Milner, and no noteworthy 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, 1920.

GAGE. Friez water-stage recorder on left bank below highway bridge, referred to 

combination vertical and inclined staff gage; installed May 28, 1919. Staff gage 

in three sections on left bank 400 yards upstream, used October 20, 1909, to May 

27, 1919, except when supplemented by an auxiliary gage at different datum in 

three sections 100 yards downstream. Datum of auxiliary gage lowered 1.00 

foot July 30 and 1.00 foot September 7, 1916. Original gage used prior to October 

20,1909, was a vertical staff on right bank at about same datum as gage used after 

that date. Observer, W. N. McConnel.

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

midway between gage and cable, or by wading. Measurements may also be made 

from suspension highway bridge immediately above gage, but measuring conditions at this bridge are poor.

CHANNEL AND CONTROL. Bed 'of stream at gage composed of lava rock, overlain 

with very light gravel deposits and occasional loose rock. Left bank high 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 the year ending September 30,1919,15.90 feet (from old auxiliary gage) at 4.50 p. m. April 6 (discharge, 

12,400 second-feet); minimum stage, about 1.63 feet July 26 (discharge, 13 secondfeet); discharge July 31 to August 21 estimated 13 second-feet also.

Maximum stage during year ending September 30, 1920, from water-stage recorder, 17.51 feet at 12.30 p. m. May 22 (discharge, 16,100 second-feet); minimum 

stage recorded, 1.65 feet July 23 and August 25 (discharge, 13.5 second-feet); 

measured discharge, 12.5 second-feet August 4.

1909-1920: Maximum stage recorded, 20.1 feet June 12, 1909 (discharge, 44,400 

second-feet); minimum stage, 1.08 feet (old datum of auxiliary gage) August 

17-18, 1915 (discharge, 9 second-feet).

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

DIVERSIONS. Twin Falls canals divert water at Milner dam, just above station. 

During part of season practically entire flow of river is taken by these canals.

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

ACCURACY. Stage-discharge relation practically permanent at both old and new 

locations of gage. Rating curve used prior to May 29, 1919, well defined below 

500 second-feet and between 2,000 and 7,000 second-feet; otherwise poorly defined. 

Curve used May 29, 1919, to September 30, 1920, well defined for stages which 

/ occurred. Auxiliary gage read to hundredths once daily prior to May 29, 1919; 

new staff gage read to hundredths twice daily May 29 to June 8, 1919; operation 

of water-stage recorder satisfactory thereafter except as indicated in footnote to 

daily-discharge table. Daily discharge ascertained by applying mean daily 

gage height to rating table except for days of sudden changes in stage for which it 

was ascertained by hourly-discharge methods, and except as indicated in footnote to daily-discharge table. Records fair prior to May 29, 1919; good thereafter.

COOPERATION. Gage-height record and several discharge measurements furnished 

by Twin Falls Canal Co.
40 SURFACE WATEB SUPPLY, 193&-1920, PART XII B.

42 STJEFACE WATER SUPPLY, 1919-1920, PAST XII B.

SNAKE RIVER NEAR TWIN FALLS, IDAHO.

LOCATION. In sec. 33, T. 9 S., R. 17 E., at Perrine's Bridge, on I. B. Perrine Blue 

Lakes ranch, 4 miles north of Twin Falls, Twin Falls County, and 4 miles below 

Shoshone Falls. Outlet of Blue Lakes enters Snake River 200 feet below gage, 

and Salmon Falls Creek enters 18 miles below.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. September 29, 1911, to June 30, 1917, and May 1, 1919, to 

September 30, 1920.

GAGE. Inclined and vertical staff on left bank 100 feet above bridge; read by T. 

C. Shawver.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge.

CHANNEL AND CONTROL. Bed of stream at measuring section very rough. Banks 

high; not subject to overflow. Control composed of lava boulders and solid 

rock; permanent.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 7.45 feet at 9 a. m. May 1 (discharge, 10,700 second-feet); minimum 

discharge, 540 second-feet June 13-16 and June 18 to August 30.

Maximum stage recorded during year ending September 30, 1920, 9.68 feet at 

6 p. m. May 22 (discharge, 18,100 second-feet); minimum stage, 2.15 feet at 5.30 

a. m. July 15 (discharge, 515 second-feet).

1911-1917; 1919-20: Maximum stage recorded, 13.3 feet at 6 a.m. and 7 p. m. 

June 10, 1914 (discharge, 32,200 second-feet); minimum stage, 2.05 feet June 27 

to July 4, July 9-16, 18-20, 28-29, and 31, August 1-3, 6, and 7, 1915 (discharge, 

468 second-feet).

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

DIVERSIONS. No water is diverted from river between this station and that at Milner, 

except by small ranch ditches.

REGULATION. Flow past station regulated directly by diversions of North Side and 

South Side canals at Milner, where practically the entire flow of the river is 

diverted during latter part of irrigation season; flow at such times consists of inflow and seepage between this station and the one at Milner.

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

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

by applying mean daily gage height to rating table. Parts of daily-discharge 

record may be somewhat in error as a result of diurnal fluctuations due to operation 

of gates at Milner dam. Records of monthly discharge good.

SNAKE RIVER NEAR HAGERMAN, IDAHO.

LOCATION. In sec. 2, T. 8 S., R, 13 &>, at Owsley'e ferry,, just above Upper Salmon 

Falls and 4 miles south of Hagenjaan, Oooding County. Big Wood River enters 

10 miles below.

DRAINAGE AREA. Not measured. 

RECORDS AVAILABLE. August 24, 1912, to June 18,1917; July 25,1919, to September

30,1920.'

GAGE. Stevens water-stage recorder on right bank 200 feet above ferry, referred to 

inside and outside vertical staff gages; installed November 15, 1916; inspected 

by Jack Clegg, Gus Conrad, and C. B. Stark. Inclined staff on left bank 5Q 

feet below ferry used prior to August 15, 1915. Vertical staff at same site used 

thereafter until November 15, 1916. All gages at same datum. 

DISCHARGE MEASUREMENTS. Made from eable 100 feet below gage. 

CHANNEL AND CONTROL. Control rocky ;pra^tipally permanent. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 3.42 feet September 24 (discharge, 5,410 second-feet); minimum stage 

pfobably occurred during August when no gage-height record was obtained.

Maximum stage during year ending September 30, 1920, probably occurred on 

May 21 of 22 when recorder was not operating; minimum discharge, 4,520 secondfeet July 15-18 and 22-24. ^ ; ?

1912-1917; 1919-20: Maximum stage recorded, 7.75 feet at 6 p. m, June 10,1914 

(discharge, 35,100 second-feet); minimum stage, 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 stages. 

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. No noteworthy diversions between this station and the one 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's ferry is maintained largely 

by springs and waste water from irrigation above.

REGULATION. Flow regulated by diversions for the Twin Falls canals at Milner. 

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

Operation of water-stage recorder unsatisfactory (see footnote to table of daily 

discharge). Daily discharge ascertained by applying to rating table mean 

daily gage height obtained by inspecting recorder graph, except as indicated 

in footnote to tables of daily discharge. Records good for periods during which 

recorder was operating; other records fair.

SHAKE RIVER AT KING HILL, IDAHO.

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

station at King Hill, Elmore County. Big Wood River enters from north 20 miles 

above station.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 13, 1909, to September 30, 1920.

GAGE. Inclined staff on right bank; installed August 17, 1910; read by E. T. Giles. 

Original gage, used May 33,1909, to March 1,1910, was vertical staff on left bank 

at practically same site as present gage, but at datum about 2.2 feet higher. 

Temporary staff gage three-fourths of a mile above, used March 7 to August 16, 

1910.

DISCHARGE MEASUREMENTS. Made from cable 100 feet below gage.

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

gravel. Control is lava reef partly overlain with gravel; shifts slightly.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 30, 1919, 9.23 feet March 30 (discharge, 18,100 second-feet); minimum stage, 

5.45 ieet July 27 and August 31 (discharge, 6,060 second-feet).

Maximum stage recorded during year ending September 30, 1920, 10.24 feet 

at 4.30 p. m. May 19 (discharge, 20,900 second-feet); minimum discharge, 6,280 

second-feet July 18 and 23.

1909-1920: Maximum stage recorded, 16.3 feet June 22, 1918 (discharge, 47,20ft 

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

(discharge, 4,760 second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS.- No important diversions for irrigation are made between this station 

and the one at Milner.

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

irrigation season practically the entire flow of river is appropriated and flow 

at King Hill is derived largely from springs and seepage water from the Twin 

Falls tracts.
RIVER BASIN.

ACCURACY. Stage-discharge relation changed during high water in March and April, 

1919. Rating curve used Octoher 1 to March 30, 1919, well defined between 

4,500 and 20,000 second-feet; curve used April 10, 1919, to September 30, 1920, 

which is a revision of the previous curve at the high-water end, well defined 

between the same limits. Gage read to hundredths once daily. Daily discharge 

ascertained by applying daily gage height to rating table except as indicated in 

footnote to table of daily discharge. Records good.

COOPERATION. Gage-height record furnished by United States Reclamation Service.

Dincharge measurements of Snake Rirer at King Hill, Idaho, during the years ending

Sept. 30, 1919 and 1920.

SHAKE RIVEK NEAR MURPHY, IDAHO. ^ '' 

LOCATION. In NW. J sec. 18, T. 2 S., R, IE., Ada County, three-quarteBS of a mile 

below Swan Falls power plant, 1J miles below, company ferry, 12 miles east of 

Murphy, Owyhee County, and 38 miles below mouth of Bruneau River.

DRAINAGE ABBA. 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, 1920.

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

ranch of S. N. Glass; installed September 7, 1914; inspected by George Bahler. 

Original gage, a temporary vertical staff, installed at this site August 29, 1912, 

was replaced October 2, 1912, by an inclined staff, and a vertical, low-water 

section was added August 22, 1913. Friez water-stage recorder, temporarily 

installed, used December 13,1913, to June 27,1914. All gages at practically same 

site and set to same datum. , i v

DISCHARGE MEASUREMENTS. Made from ferryboat 1J miles above gage.

CHANNEL AND CONTROL. Bed composed of lava rock with deposits of sand, silt, and 

gravel, where not scoured out by current. Control practically permanent. 

Banks not subject to overflow.

EXTREMES OF DISCHARGE. Maximum stage during year ending September 36, 

1919, from water-stage recorder, 6.43 feet at 7 p. m. March 31 (discharge, 19,000 

second-feet); minimum mean daily stage, -1.12 feet July 30 (discharge,.6,190 

second-feet); absolute minimum not definitely known because water fell below 

intake pipe at times of minimum load at power plant above.

Maximum stage recorded during year ending September 30, 1920, from waterstage recorder, 7.87 feet at 2 p. m. May 24 (discharge, 23,500 second-feet); minimum 

mean daily stage, 1.28 feet July 26 (discharge, 6,080 second-feet); absolute 

minimum not definitely known because water fell below intake at times of minimum load at power plant above.

1912-1920: 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 above during low-water periods in 1919 

and 1920.

ICE. Stage-discharge relation not affected by ice.

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

this station and the one at King Hill. ,-,

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

dam above 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. Rating curve well defined. Operation of water-stage recorder satisfactory except as indicated in footnote to 

tables of daily discharge. Daily discharge ascertained by applying to rating table 

mean daily gage height obtained by inspection of recorder graph except as indicated in footnote to table of daily discharge. Records good.

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

Sept. 30, 1919 and 1920.

30, 1919, 9.9 feet April 5 (discharge, 53,800 second-feet); minimum stage, 1.5 

feet August 1 (discharge, 5,550 second-feet).

Maximum stage recorded during year ending September 30, 1920, 10.03 feet 

at 9 a. m. December 24 (stage-discharge relation affected by an ice jam; discharge 

not determined); maximum open-water stage recorded, 7.61 feet at 9 a. m. May 

24 (discharge, 36,900 second-feet); minimum stage, 1.6 feet at 9 a. m. July 31 

(discharge, 5,860 second-feet).

1910-1920: Maximum stage recorded, 14.5 feet (United States Geological Survey datum) June 15, 1912 (discharge, 73,800 second-feet); minimum stage, 1.5 

feet (Weather Bureau datum) August 28 and 29, 1915, and August 1, 1919 (discharge, 5,550 second-feet). A stage of 15.7 feet was observed March 3, 1910, on

52 SURFACE WATER SUPPLY, 1919-1920, PART XII B.

ICE. Stage-discharge relation occasionally affected by ice.

DIVERSIONS. Some water is diverted between Weiser and the station near Murphy 

by pumping.

REGULATION. Diurnal fluctuations during periods of low water due to operations at 

Swan Falls power plant above.

ACCURACY. Stage-discharge relation permanent except aa affected by ice. Rating 

curve well defined. Gage read to tenths once daily October 1 to July 5, 1919, 

and to hundredths once daily July 6, 1919, to September 30, 1920. Daily discharge ascertained by applying daily gage height to rating table except for periods 

December 16-30, 1919, and January 10-17, 1920, during which stage-discharge 

relation was affected by ice, for which mean discharge was ascertained by means 

of weather records and comparison with flow of adjacent streams. Open-water 

records good except for low-water periods, for which they are only fair on account 

of diurnal fluctuation; winter records fair.

COOPERATION. Gage-height record furnished by Weather Bureau.

SURFACE WATER SUPPLY, 1919-1920, PART XII B.

SNAKE RIVER AT RIPARIA, WASH.

LOCATION. In sec. 31, T. 13 N., R. 38 W., at Oregon-Washington Railroad & Navigation Co.'s bridge at Riparia, Whitman County.

DRAINAGE ABEA. 102,000 square miles (measured by Weather Bureau).

RECORDS AVAILABLE. October 1, 1915, to September 30, 1920. Gage-height record 

during parts of May and June, 1900 to 1902, May 1 to November 30, 1904, July 1, 

1905, to December 31, 1906, February 1, 1908, to June 30, 1910, and August 1T 

1910, to February 28, 1917, obtained and published by Weather Bureau.

GAGE. Chain gage on railroad bridge installed September 12, 1917; read by W. W. 

Pickett, jr. Previous gage was vertical staff in three sections; referred to same 

datum.

DISCHABGE MEASUBEMENTS. Made from railroad bridge.

EXTREMES OF DISCHABGE. Maximum stage recorded during year ending September 

30, 1919, 13.3 feet at 8 a. m. May 30 (discharge, 167,000 second-feet); minimum 

stage, 0.1 foot August 28 to September 5 (discharge, 10,900 second-feet).

Maximum stage recorded during year ending September 30, 1920, 12.2 feet at 

9 a. m. June 17 (discharge, 148, 000 second-feet); minimum stage occurred in December when stage-discharge relation was affected by ice; discharge probably 

less than 12,000 second-feet.

1916-1920: Maximum stage recorded, 18.2 feet May 30, 1917 (discharge, 256,000 

second-feet); minimum stage, 0.1 foot August 28 to September 5, 1919 (discharge, 

10,900 second-feet); discharge may have been less in December, 1919.

Maximum stage recorded, as published by United States Weather Bureau, 24.7 

feet June 5, 1894 (discharge from extension of rating curve, 409,000 second-feet).

CHANNEL AND CONTBOL. Control for low stages is sand and gravel channel above 

Texas Rapids; shifting. For high stages, control is solid lava bed of Texas Rapids 

half a mile below gage; permanent.

ICE. Stage-discharge relation occasionally affected by ice.

DIVEBSIONS. A large amount of water is diverted above gage for irrigation.

REGULATION. Flow is partly regulated by storage in Jackson Lake reservoir (capacity, 

847,000 acre-feet), Arrowrock reservoir (capacity about 280,000 acre-feet), Deer 

Flat reservoir (capacity, 177,000 acre-feet), and in other smaller reservoirs in the 

basin; also by diversions for irrigation.

ACCURACY. Stage-discharge relation for low water changed gradually from January 22 

to February 26, 1919; affected by ice December 1-29, 1919. Rating curves well 

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

applying daily gage height to rating table except for period January 24 to February 25, 1919, for which it was ascertained by shifting-control method, and 

except for periods indicated in footnote to table of daily discharge. Records 

good except those for period of ice effect.

was a vertical staff at different datum, attached to crib pier of Ora highway 

bridge.

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

CHANNEL AND CONTROL. Bed composed of coarse gravel. Control not well denned; 

shifts slightly during high stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 2.50 feet at 6.30 

p. m. May 16 (discharge, 5,130 second-feet); minimum stage, 0.64 foot April 25 

and 26 (discharge, 1,150 second-feet).

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 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 for the 

period June 1,1919, to September 15,1920.

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

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

to hundredths daily. Records considered good.

IjfflNRYS FOEK AT ST. ASTHOinr, IDASW.

LOCATION. IB sec. 1, T. 7 N., R. 40 E., half a mile upstream from, bridge on main 

street of St. Anthony, Fiemont County, and 9 miles below mouth of Pall River.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. March 26, 1919, to September 30, 1920.

GAGE. Inclined staff on right bank; read by employees of Utah Power & Light Co.

DISCHARGE MEASUREMENTS. Made from cable about 600 feet below gag£*

CHANNEL AND CONTROL. Bed composed of coarse gravel and outcrops of lava. One 

channel at all stages. Control shifts slightly at high stages.

EXTREMES OF DISCHARGE, Maximum stage recorded during year ending September 

30,1919, 5,70 feet May 1 (discharge, 6,210 second-feet); minimum stage, 2.30 feet 

August 29 (discharge, 615 second-feet).

Maximum stage recorded during year ending September 30, 1920, 5.70 feet 

May 19 (discharge, 5,500 second-feetV, minimum stage recorded, 2.15 feet July 

15 and 16 (discharge, 545 second-feet); actual minimum stage probably occurred 

July 23 and 24 (discharge, estimated 530 second-feet).

ICE. Stage-discharge relation seriously affected by ice. Observations discontinued 

during winter.

DIVERSIONS. Numerous diversions above and below station.

REGULATION. Flow affected by manipulation of canal headgates above station and 

by operation of Ashton and St. Anthony power plant about 17 miles upstream.

ACCURACY. Stage-discharge relation practically permanent during year ending 

September 30, 1920. Rating curve well defined between 750 and 3,500 secondfeet; extended outside those limits. Gtage read to hundredths once daily. Daily 

discharge ascertained by applying daily gage height to rating table except as 

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

No discharge measurements were made during 1919 at stages above 3.33 feet 

(disqharge, 1,640 second-feet). Discharge above that stage based on extension 

of rating curve, which is not substantiated by high-stage measurements of subsequent years; hence records for the year may be considerably in error above 

about 2,000 second-feet. These records are published as furnished.

CoopERATioN.-^Complete record for the period March 26 to September 30, 1919, 

gage-height record for 1920, and several discharge measurements furnished by 

Utah Power & Light Co.

DIVERSIONS FROM HENRYS FORK BETWEEN ST. ANTHOWT AND REXBTTRG GAGING

STATIONS, IDAHO.

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

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

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

of Reclamation to facilitate distribution of the water. Records are available for the 

period June 1,1919, to September 15,1920.

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

and by operation of check gates. Rating curves well defined. Gages read to hundredths daily. Records considered good.

Combined daily discharge, in second-feet, of e&nah diverting from Benrys Fork,, between 

St. Anthony and R&anarg gaging stations, for (he i'frigation seasons of1919 and 1920.

ICE. Stage-discharge relation seriously affected by ice. Observations discontinued 

during winter.

DIVERSIONS. A large percentage of the natural summer flow diverted above station.

REGULATION. None except that due to operation of headgfctes of irrigation canals.

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

well denned; used direct for periods April 27-30 and September 30 to November 26, 1919, and April 10 to May 19 and July 13, 1920; indirect method for shifting control, based on frequent discharge measurements, used for other periods. 

Operation of water-stage recorder satisfactory except during periods May 25-30, 

September 7-12 and October 19 to November 7, 1919, and April 1-9, 19-23, May

and half a mile northeast of Warm Kiver, Fremont County. Eobiason Creek 

enters a quarter of a mile below station.

DRAINAGE AREA. 144 square miles (measured on Forest Service maps).

EECORDS AVAILABLE. January 24,1912, to March 22,1915; April 3» 1918, to September 30,1920. 

GAGE. Vertical staff on downstream side .of new bridge bent; installed April 27, 

1920; read by Axel Anderson. Original gage at similar location on old bridge 

destroyed June 24, 1919. Two auxiliary gages used July 10, 1919, to April 26, 

1920. All gages at slightly different datum.

DISCHARGE MEASUREMENTS. Made by wading near gage.

CHANNEL AND CONTROL. Bed composed of large cobbles or boulders in gravel 

drift. Control shifts slightly. Stage-discharge relation affected by growth of 

aquatic plants.

EXTREMES OF DISCHARGE. Maximum discharge during year ending September 30, 

1919, 492 second-feet April 26-29; minimum stage recorded, 1.30 feet December 

10-13, January 15, February 21, 22, 25, March 4, 9, 10, 12, 14-16, and 24 (discharge, 197 second-feet).

Maximum stage recorded during year ending September 30, 1920, 2.2 feet 

(present gage) May 13 (discharge, 575 second-feet); minimum stage, 13 feet 

(auxiliary gage) February 8-10, 15-22, 24-29, and March 1-6 (discharge, 17$ 

second-feet).

1912-1915; 1918-1920: Maximum stage recorded, 2.3 feet (original gage) June 2, 

1912 (discharge, 900 second-feet); minimum stage, 1.3 feet (auxiliary gage) 

February 8-10, 15-22, 24-29, and March 1-6, 1920 (discharge, 173 second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. None above station.

BEGULATION. None.

ACCURACY. Stage-discharge relation affected by shifting control and by changes in 

position and datum of gages. Three fairly well defined standard rating curves 

used, applicable October 1,1918, to April 7,1920, April 8 to June 23,1920, and July 

1 to September 30,1920; curves used direct October 1, 1918, to April 15,1919, and 

April 27 to September 30, 1920; indirect method for shifting control used for 

remaining periods. Gage read to half-tenths once daily. Daily discharge 

ascertained by applying daily gage height to rating table except for periods for 

which shifting-control method was used, and except as indicated in footnote to 

table of daily discharge. Eecords fair.

DIVERSIONS PROM FAIX RIVER ABOVE e&ai*a? BTATJOH WEAR SQTJIRRBI,, IDABO.

Above the 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 Bepartment of Reclamation to 

facilitate distribution of the water. Records are available for the period June 1, 1919, 

to September 15,1920.

Stage-discharge relation oti most of the canals is affected by growth of aquatic plants. 

Rating curves well defined. Gages read to hundredths daily. Records considered 

good.

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

station near Squirrel, Idaho, for the irrigation seasons of 1919 oftd 1920.

Original gage was a vertical staff attached to bridge at Wilson's sawmill- 3 miles 

upstream.

DISCHARGE MEASUREMENTS. Made from cable 200 feet below gage or by wading.

CHANNEL AN£> CONTROL. Bed composed of boulders in gravel drift. Control formed 

by riffle below gage; fairly permanent. Banks high, clean, and not subject to 

overflow. One channel at all stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 6.25 feet at 6 p. m. May 29 (discharge, 4,730 second-feet); minimua* 

stage, 1.80 feet September 26 and 27 (discharge, 344 second-feet).

Maximum stage recorded during year ending September 30, 1920, 4.16 feet at 

10.30 a. m. June 12 (discharge, 2,900 second-feet); minimum stage, 1.67 feet 

February 26 and 27 (discharge, 279 second-feet).

1904-3909: 1918-1920; Maximum stage recorded, 5.6 feet, June 14, 15, and 23, 

1918 (discharge, 5,380 second-feet); minimum stage, 1.4 feet April 5, 1905 (discharge, 168 second-feet).

ICE. Silage-discharge relation occasionally affected by ice.

DIVERSIONS.- Three irrigation canals divert above- station.

REGULATION. None except that due to headgate changes on canals above station.

ACCURACY. Stage-discharge relation practically permanent except as affected by ice. 

Two well defined rating carves used, the first applicable October 1, 1918, to 

May 25, 1919, ths second applicable May 26, 1919, to September 30, 1920; the 

second curve differs from the first only in that it better averages later discharge 

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

DIVERSIONS FROM FALL RIVER BETWEEN SQ

TIONS, IDAHO.

AND CHESTER GAGING STABetween Squirrel and Chester gaging stations nine separate canals divert water 

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

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

Reclamation to facilitate distribution of the water. Records are available for the 

period June 1,1919, to September 15,1920.

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

and by operation of check gates. Rating curves iairly well defined. Gages read to 

hundredths daily. Records considered good.

DIVERSIONS FROM TETOK RIVER BETWEEN GAGING STATION NEAR ST. ANTHONY 

AND MOTTTH OF RIVER, IDAHO.

Between the gaging station near St. Anthony and mouth «f river fourteen Beparate 

canals divert water from Teton Elver 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 for the period June 1,1919, to September 15,1920.

Stage-discharge relation on these canals is seriously affected by growth of aquatic 

plants. Rating curves fairly well defined. Gages read to hundredths daily. Records 

considered fair.

DISCHARGE MEASUREMENTS. Made from cable 200 feet downstream from gage or by

CHANNEL AND CONTROL. Bed composed of boulders in gravel drift; fairly permanent. Left bank is overflowed at high stages; both banks are brush covered.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30,1919, 9.83 feet at 5.05 p. m. April 24 (discharge, 1,650 second-feet); minimum 

stage, 1.91 feet August 27-29 (discharge, 13 second-feet).

Maximum stage recorded during year ending September 30, 1920, 12.1 feet at 

10 a. m. May 9 (discharge,' 2,550 second-fee4;); minimum stage, 2 13 feet February 

28 (discharge, estincated because of ice, 24 second-feet).

1916-1920: Maximum stage recorded, 16.3 feet May 15, 1917 (discharge, 4,200 

second-feet); minimum stage, 1.91 feet August 27-29, 1919 (discharge, 13 secondfeet).

ICE. Stage-discharge relation seriously affected by ice; data inadequate for determination of daily discharge.

DIVERSIONS. No irrigation canals of any consequence above station.

REGULATION. None.

ACCURACY. Stage-discharge relation for low stages changed during winter of 1918-19, 

and again following the high water of May, 1920; seriously affected by ice. 

Rating curves used October 1 to December 22,1918, and March 24,1919> to June 

2, 1920, well defined; curve used June 3 to September 30, 1920, well defined 

above 600 second-feet and fairly well defined below that point. Gage read to 

hundredths once daily. Daily discharge ascertained by applying daily 

height to rating table except for periods of ice effect and for days of no gage readi ng 

for which it was ascertained as indicated in footnote to daily-discharge tables. 

Open-water records for 1919, good; for 1920, fair; winter records, poor.

EIVER BASIN.

GRAYS LAKB OUTUET K»AB. BCEBMAH, IDAHO.

LOCATION. In sec. 15, T. 3 S., R. 42 E., 3 miles below bridge at outlet of lake and 

3J miles west of Herman, Bonneviile County.

DRAINAGE AREA. Not measured. '

RECORDS AVAILABLE. Aprils, 1916, to September 30, 1920.

GAGE. Stevens continuous water-stage recorder on right bank; installed April 20, 

1918; inspected by Thomas Priest. Prior to April 20, 1918, vertical staff at 

same location and datum.

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

CHANNEL AND CONTROL. Channel composed of gravel and small cobbles; left bank 

subject to overflow at gage height of about 3.5 feet. Control is rock ledge 25 

feet below gage; fairly permanent.

EXTREMES OF DISCHARGE. Maximum stage during year ending September 30,1919, 

from water-stage recorder, 4.45 feet for several hours April 23 (discharge, 544 

second-feet); minimum stage, 0.73 foot August 25 (discharge, 1.3 second-feet). 

A lower discharge probably occurred during period of no record.

Maximum stage recorded during year ending September 30, 1920, 4,2 feet 

(staff gage reading) at 3.30 p. m. May 18 (discharge, 485 second-feet); minimum 

stage, 0.63 foot August 30 and 31 (discharge, 0.5 second-foot). A higher maximum 

discharge may have occurred during period of no record.

1916-1920: Maximum stage recorded, 5.9 feet at 9 a. m. May 15,1917 (discharge, 

1,350 second-feet); minimum stage, 0.63 foot August 30 and 31, 1920 (discharge, 

0.5 second-foot).

ICE. Ice practically stops flow from lake at times, but springs probably keep channel 

near gage free from ice. Observations discontinued during winter.

DIVERSIONS. No diversions between lake and station. Diversions for irrigation are 

made above lake, but amount of water diverted is not known.

REGULATION. No artificial regulation above station.

ACCURACY. Stage-discharge relation practically permanent. Two fairly well-defined 

rating curves used, applicable during period of record in 1919 and 1920^ respectively. Operation of recorder not entirely satisfactory. Daily discharge ascertained by applying to rating table mean daily gage height obtained by inspection 

of recorder graph and by interpolating or estimating for periods of no gage-height 

record. Records good from later part of May to July, 1920; fair for other periodsDischarge measurements of Grays Lake outlet near Herman, Idaho, during the years ending

Sept. SO, 1919 and 1920.

30, 1919* 3.54 feet June 25 (discharge, 371 second-feet); minimum discharge, 

practically no flow during period of no record, when headgates were closed.

Maximum stage recorded during year ending September 30, 1920, 4.83 feet 

at 9.45 a. m. August 12 (discharge, 486 secohd-feet); minimum discharge, practically no flow during period of no record, when headgates were closed.

1912-1920: Maximum stage recorded, 4.83 feet August 12, 1920 (discharge, 

486 second-feet); minimum discharge, practically no flow during period of no 

record, when headgates were closed.

ICE. Canal not operated during winter.

DIVERSIONS. None.

REGULATION. Flow controlled at headgates 600 feet above.

ACCURACY. Stage-discharge relation not permanent. Two standard rating curves 

used; one, applicable October 1, 1918, to September 30, 1919, well defined; the 

other, applicable May 23 to September 30,1920, well defined above 175 secondfeet and extended below that point on basis of previous curve; curve used direct 

for period June 11 to July 15, 1920; indirect method for shifting control used for 

other periods of record except June 27 to September 30,1919, during which period 

headgates of canal were closed and observer made daily estimates of leakages 

through gates. Gage read to humdredths once daily. Daily discharge for the 

period June 11 to July 15, 1920, ascertained by applying" daily gage height to 

rating table; for other periods of record it was ascertained by shifting-control 

method, from observer's estimates, or as noted in footnote to table of daily discharge. Records good. <

BLACKFOOT RIVER ABOVE RESERVOIR, NEAR HENRY, IDAHO.

LOCATION. About sec. 9, T. 7 S., R, 42 E., at Gully's ranch, 1£ miles above flow 

line of Blackfoot-Marsh reservoir, 7 miles south of Henry, Caribou County, and 

13 miles north of Soda Springs.

DRAINAGE ABBA. 360 square miles (measured on Land Office map).

RECOKDS AVAILABLE. March 25, 1914, to September 30, 1920.

GAGE. Vertical staff on right bank half a mile above Cully's house and 200 feet 

below shearing plant; used October 22f 1914, to October 11, 1917, and June 11, 

1919, to September 30, 1920; read by Mrs. A. C. Swanson. The original gage,
EIVEB BASIK, 93

in use prior teOctober 22, 1914, was a vertical staff attached to stream-ward side 

of right pier of bridge, three-quarters of a mile upstream. Gage used October 12. 

1917, to June 10, 1919, was an inclined staff at practically the same location as 

present gage.

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

CHANNEL AND CONTROL. One channel at ordinary stages; two to three channels at 

high stages. Bed composed of loose rock and bouldera and some gravel. Control of loose rock; fairly permanent. , '

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 4.78 feet, at 6 p. m. April 23 (discharge, 1,100 second-feet); minimum 

stage, 0.98 foot at noon August 17 (discharge, 23 second-feet). A lower discharge 

may have occurred during winter period.

Maximum stage recorded during year ending September 30, 1920, 5.96 feet at 

2 p. m. May 14 (discharge, 1,680 second-feet); minimum stage, 1.20 feet at 3.30 

p. m. November 12 (discharge, 38 second-feet). A lower discharge may have 

occurred during winter period.

1914-1920: Maximum stage, estimated from high-water mark above gage, 

6.85 feet May 16, 1917 (discharge, 2,060 second-feet); minimum stage recorded, 

0.98 foot August 17, 1919 (discharge, 23 second-feet); a lower discharge probably 

occurred during winter period.

ICE. Stage-discharge relation seriously affected by ice. Observations discontinued 

during winter.

DIVERSIONS. A few small ranch diversions are made above gage.

REGULATION. None. Entire flow past gage is impounded in Blackfoot-Marsh 

reservoir 1£ miles below.

ACCURACY. Stage-discharge relation slightly shifting; affected by ice November 

23-30, 1918, November 14, 19-30, 1919, and April 1-9, 1920. Standard rating 

curve used October 1 to November 22, 1919, fairly well defined; used direct 

October 17 to November 22; shifting-control method used prior to October 17. 

Curve used March 29 to September 30, 1919, well defined above 200 second-feet 

and fairly well defined below that point; used direct. Curve used October 1 

to November 18, 1919, practically the same as preceding curve; used direct. 

Curve used April 10 to September 30, 1920, well defined above 200 second-feet 

and fairly well defined below that point; used direct April 10 to July 22; shiftingcontrol method used July 23 to September 30. Gage read to quarter-tenths once 

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

except for periods during which shifting-control method was used, and except 

as indicated in footnote to daily-discharge table. Records good except those for 

periods during which shifting-control method was used or stage-discharge relation 

was affected by ice, which are fair. Records for October and November, 1918, 

subject to some error owing to uncertainty regarding corrections for gage shifts.

ICE. Stage-discharge relation not seriously affected by ice, presumably because of 

proximity of station to reservoir.

DIVERSIONS. Few. small diversions for irrigation above reservoir.

REGULATION. Flow entirely regulated by storage in reservoir which has a capacity 

of about 300,000 acre-feet.

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

of aquatic plants. Two rating curves used; one applicable October 1, 1918, to 

September 30,1919, fairly well defined between 20 and 900 second-feet, the other 

applicable October 1, 1919, to September 30, 1920, well defined between 8 and 

1,000 second-feet. Operation of water-stage recorder satisfactory August 30 to 

September 30, 1919. Staff gage read to hundredths twice daily during other 

periods. Daily discharge ascertained by applying mean daily gage height from 

recorder graph or from staff gage to rating table, except as indicated in footnote to daily-discharge tables. Records good except those for periods of 

estimation.

COOPERATION. Gage-height record furnished by United States Indian Service.

BLACKFOOT HIVER NEAR SHELLEY, IDAHO.

LOCATION. In sec. 7, T. 2 S., R. 38 E., 1J miles above mouth of canyon, 3 miles above 

N. A. Just's ranch, 10 miles southeast of Shelley, Bingham County, and 18 miles 

northeast of Blackfoot. Below all important tributaries.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE.- June 26, 1909, to September 30, 1920. From March 23, 1908, 

to December 31,1909, records were obtained near Presto, about 5 miles below site 

of present station. No tributaries enter between the two sites, but during irrigation season several canals divert probably 50 second-feet.

GAGE. Friez water-stage recorder on right bank; inspected by Rufus E. Reid,

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

CHANNEL AND CONTROL. Bed rocky and rough. One channel at all stages. Control 

somewhat shifting.

EXTREMES OF DISCHARGE. Maximum stage during year ending September 30, 1919i 

from water-stage recorder, 5.24 feet at 7.30 p. m.'May 29 (discharge^ 9Q7 secondfeet) ; minimum stage, 2.83 feet at midnight January 23 (discharge, about 15 secondfeet; ice jam above station retarded flow temporarily).

Maximum stage during year ending September 30, 1920, from water-stage 

recorder, 5.55 feet at 5 a. m. June 11 (discharge, 1,240 second-feet); minimum 

stage, 3.00 feet at 5 a. m. December 27 (discharge, about 23 second-feet); a lower 

flow may have occurred during period of ice effect.

1909-1920: Maximum stage recorded, 5.86 feet at 11.46 p. m, April 1,1913 (discharge, 1,420 second-feet); minimum stage, 2.83 feet at midnight January 23,1919 

(discharge, about 15 second-feet; ice jam above station retarded flow temporarily).

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. None of consequence from river or tributaries above station.
100 -B.

. Mow regulated largely by storage in Blackfoot-Marsh reservoir of 

United States Indian Service, about 40 miles upstream.

ACCURACY. Stage-discharge relation changed slightly April 7, 1920; seriously affected 

by ice. Two rating curves used, both fairly well defined above 50 second-feet, 

one applicable prior to April 7,1920, the other applicable thereafter; shifting-control method used April 7, 1920. Operation of water-stage recorder fairly satisfactory, except during periods of ice effect, when occasional staff gage readings were 

'obtained. Daily discharge ascertained by applying to rating table mean daily 

gage height obtained by inspection of recorder graph, except for periods of ice effect and for periods of no record as indicated in footnote to table of daily discharge. 

Open-water records good, except those for October and November, 1919, which are 

fair; winter records fair.

102 SURFACE WATER SHJPPKY, 191^-1920, PART XH B.

BLACKFOOT RIVER WEAK BLACKFOOT, IDAHO.

LOCATION. In sec. 27, T. 3. S., R. 34 E., at old Jarvis ranch, 2 miles above junction

with Snake River and 8 mile* southwest of Blackfoot, Bingham County. 

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. Jaly 27, 1913, to September 30, 1920. 

GAGE. Inclined staff on right bank half a mile south of Jarvis ranch house; read by

Oliver L. Kofoed.

DISCHARGE MEASUREMENTS. Made from cable 100 yards below gage or by wading. 

CHANNEL AND CONTROL. Bed composed of gravel. Control presumably of same

material; fairly permanent. One channel at all stages. Banks covered with

heavy growth of brush and willows which may affect stage-discharge relation at

high stages. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September

30, 1919, 6.52 feet at 6.30 p. m. June 2 (discharge, 304 second-feet); minimum

discharge, no flow, on several days. 

Maximum stage recorded during year ending September 30, 1920, 7.7 feet at

I p. m. August 29 (discharge, 501 second-feet); minimum discharge, no flow, June 

18 and 19.

1913-1920: Maximum stage recorded, above 9.3 feet during period June 15-18» 

1918, when stage-discharge relation was affected by overflow and by backwater 

from Snake River; maximum discharge recorded, 673 second-feet September 21 

and 22,1914; minimum discharge, no flow, on several days during 1919 and 1920.

ICE. Observations discontinued during winter. .

DIVERSIONS. Principal diversions above gage are the Fort Hall canals near Blackfoot; several smaller diversions also made near Blackfoot.

REGULATION. Flow regulated by storage in the Balckfoot-Marsh reservoir of the 

United States Indian Service, and by manipulation of canal headgates above 

station.

ACCURACY. Stage-discharge relation changed^ slightly during period of no flow July

II to August 11,1919. Standard rating curve used May 26 to September 30,1919, 

fairly well defined; used direct May 26 to July 10; parallel curve used August 12 to 

September 30. Fairly well defined curve used during 1920; practically the same 

as standard curve for 1919. Gage read to hundredths once daily. Daily discharge 

ascertained by applying daily gage height to rating table except as indicated in 

footnote to daily-discharge table. Records fair.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 30, 1919, 2.30 feet about 7 p. m. April 19, 20, and 21 (discharge, 115 secondfeet); minimum stage, 1.03 feet (original gage datum) at 8.30 a. m. January 8 

(discharge, about 6.9 second-feet); owing to lack of actual discharge measurements 

during period of minimum discharge this figure should be used with caution. 

Maximum stage recorded during year ending September 30, 1920, 2.90 feet at 

8.30 a. m. May 9 (discharge, 179 second-feet); minimum discharge, estimated 

8.4 second-feet February 7.

1914-1920: Maximum stage recorded, 3.5 feet at 8 p. m. April 19, 1914 (discharge from extension of rating curve, 292 second-feet); minimum discharge, 

' about 6.9 second-feet January 8,1919.

ICE. Stage-discharge relation not affected by ice because of warm springs.

DIVERSIONS. One small diversion above station and one below.

REGULATION. No artificial regulation.

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

curve used prior to August 19, 1919, when new gage was installed, fairly well 

defined; was used direct December 30, 1918, to May 4, 1919, and as basic curve 

for shifting-control method for other periods. Rating curve used beginning 

August 19,1919, fairly well defined between 12 and 90 second-feet, poorly defined 

below 12 second-feet and above 90 second-feet based upon form of previous curve; 

was used direct August 19 to September 13, and September 26 to November 26, 

1919, and May 4-13 and September 12-30, 1920, and as basic curve for shiftingcontrol method for other periods. Gage read to hundredths twice daily. Daily 

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

for periods for which shifting-control method was used and except as indicated 

in footnote to table of daily discharge. Records of discharge for individual days 

during certain periods may be subject to error, but records of monthly discharge 

are fair.

MEADOW CREEK NEAR HENRY, IDAHO.

LOCATION. In sec. 3 T. 6 S., R. 42 E., half a mile above flow line of Blaekfoot.

Marsh reservoir, three-fourths of a mile below Goose Lake or Pelican Slough,

and 1* miles northeast of Henry, Caribou County. 

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 20,1914, to September 30,1920. 

GAGE.1 Stevens water-stage recorder on left bank; installed June 27,1914. Vertical

staff at same location and datum used April 20 to June 26, 1914. Observers!

Mrs. W. J. Chester and Ray Christensen.

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

CHANNEL AND CONTROL. Control originally an old rock diversion dam about 100

feet below gage; was torn out August 17-19, 1915, and stage-discharge relation

completely changed. New control composed of rocks and gravel; somewhat

shifting. One channel at all stages; banks very brushy. « EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September

30,1919, from water-stage recorder, 3.93 feet April 22 (discharge, 210 second-feet);

minimum discharge probably somewhat less than 0.5 second-foot during July.

Maximum stage recorded during year ending September 30,1920, from waterstage recorder, 4.25 feet at 4 p. m. May 11 (discharge, 283 second-feet); minimum

discharge probably somewhat less than 2 second-feet during latter part of June. 

1914-1920: Maximum stage recorded, 4.81 feet May 1.7, 1917 (discharge, 424

second-feet); minimum discharge probably somewhat less than 0.5 second-foot

during July, 1919. 

ICE. Stage-discharge relation seriously affected by ice. Observations discontinued

during winter.

DIVERSIONS. Some water used for irrigating hay and pasture lands above. 

REGULATION. Goose Lake or Pelican Slough acts as'a regulating basin.
BIVEIfc BASIN". 107

ACCURACY.--Stage-dMjarge relation not permanent. Two fairly well defined rating 

curves used, one applicable April 12 to May 8, 1919, and August 16, 1919, to 

September 30, 1920, the other May 16 to August 13, 1919. Operation of waterstage recorder unsatisfactory. Daily discharge-ascertained by applying to rating 

table mean daily gage height obtained by inspecting recorder graph except as 

indicated in footnote to table of daily discharge and except for the periods 

August 14-15,1919, and June 12-24,1920, for which it was ascertained by means 

of the indirect method for.shifting control. Records fail?.

LOCATION. In sec. 13, T. 2 S., E. 36 E., 100 feet above double metal flume by which 

canal crosses Eastern Idaho Slough, a quarter of a mile below nearest highway 

bridge, 1£ miles below point where Sand Creek crosses canal, and 5 miles southeast of Firth, Bingham County.

RECORDS AVAILABLE. March 29,1914, to September 30,1920.

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

Jensen, and William Hall.

DISCHARGE MEASUREMENTS. Made from one of the highway bridges above or by 

wading.

CHANNEL AND CONTROL. Bed composed of silt, sand, and fine gravel; may shift 

 slightly, but flume heading just below probably furnishes permanent control for 

high stages. Point of zero flow at gage height about 0.5 foot.

EXTREMES OF DISCHARGE. Maximum stage during year ending September 30, 1919, 

from water-stage recorder, 5.27 feet at 6 a. m. October 10 (discharge, 417 secondfeet); canal dry during winter period.

Maximum stage during year ending September 30, 1920, from water-stage recorder, 5.68 feet at 2 p. m. September 26 (discharge, 474 second-feet); canal dry 

during winter period.

1914-1920: Maximum stage recorded, 5.68 feet September 26, 1920 (discharge, 

474 second-feet); c3hal dry during several periods.

ICE. Stage-discharge relation seriously affected by ice. No flpw permitted during 

winter.

DIVERSION None.

REGULATION. Flow partly regulated by Snake River head gates, 12 miles above, and 

partly by gates at Sand Creek crossing, 1£ miles above.

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

defined. Operation of water-stage recorder satisfactory except as indicated in footnote to daily-discharge table. Daily discharge ascertained by applying to rating 

table mean daily gage height obtained by inspection of recorder graph except as 

noted in footnote to daily-discharge table. Records goqd for 1919; excellent for 

1920. 

Idaho (Government) canal diverts water from left bank of Snake River in sec. 31, T.

1 N., R. 37 E., and discharges into Biackfoot River in sec. 24, T. 2S., R.36 E. The

canal also receives water from Sand Creek 1£ miles above this station.

SAND CREEK NEAR FIRTH, IDAHO.

LOCATION. In sec. 7, Tf 2 S., R. 37 E., 400 feet downstream from point where Idaho 

(Government) canal crosses creek and 4 miles east of Firth, Bingham County.

RECORDS AVAILABLE. December 21, 1916 to September 30, 1920.

GAGE, Vertical staff on left bank on upstream side of highway bridge; read by J. A. 

Vaughn and'P. W. Wernette. Prior to May 17, 1917, vertical staff on left bank, 

300 feet upstream.

DISCHAUGE MEASUREMENTS. Made from highway bridge, from small flume crossing 

creek 50 feet downstream, or by wading.

CHANNEL AND CONTROL. Bed composed of silt, sand, and fine gravelj ahifting. 

Banks clean; subject to overflow at high stages. Point of zero flow at gage height 

about 0.1 foot; determined August 20,1919.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 4.34 feet at 7 a. m. April 3 (discharge, 348 second-feet); minimum digcharge, no flow, June 5-7, 9-20, July 31, August i-15, 22-31, September, 1-7, 10, 

14, 15,18-22, 26, 27, and 29 (regulation headgates closed).

Maximum stage recorded during year ending September 30, 1920, 4.1 feet. 

December 19 and March 18 (stage-discharge relation affected by ice); maxjmtinj 

discharge, 267 second-feet, at 8.30 a. m. May 15 (gage height, 3.56 feet); minimum 

discharge, no flow, October 1, June 26-28, and August 22-28 (regulation head* 

gates closed).

1916-1920: Maximum stage recorded, 4.34 feet at 7 a. m. April 3, 1919 (discharge, 348 second-feet); minimum discharge, no flow, on numerous dates whea 

regulation headgates were closed.

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. None between Idaho (Government) canal crossing and station.

REGULATION." Idaho (Government) canal which crosses the creek 400 feet above 

station receives entire flow of creek as tributary, and regulates flow returned to 

creek below by means of headgates. Above this point the creek channel is 

utilized as a waste ditch for numerous canal systems.
111

AccuftAtY. StageidiBbhttrge relation changed during each winter period; seriotBly 

affected by ice. Eating curve used prior to winter of 1918-19, well defined; 

curve used thereafter until beginning of winter of 1919-80, well defined below 

250 second-feet and extended above that point; curve used after winter of 1919-20, 

well defined below 240 second-feet and extended above that point. Gage read 

to hmdredths once daily during 1919, and to quarter-tenths once daily during 

1920, Daily discharge ascertained by applying daily gage height to rating table 

except for periods of ice effect and days of sudden changes in stage, as noted in 

footnote to daily-discharge tables. Open-water records fair; winter records 

sub] set to error.

14,1914; and May 11 to September 30, 1920.

GAGE. Friez water-stage recorder on left bank; installed June 17, 192O; referred to 

outside vertical staff which was used May 11 to June 16,1920. A vertical staff at 

same site but at a datum 2.07 feet higher was used June 7,1912, to November 14, 

1914. Prior to June 7, 1912, a vertical staff on left bank 100 feet below present 

gage and at a different datum, was used. Observers, Mrs. John Howell and 

Edward Mulligan.

DISCHARGE MEASUREMENTS. Made from cable a Quarter of a mile below gage or by 

wading.

CHANNEL AND CONTROL. Bed composed of sand, gravel, and cobbles. Channel 

straight. Banks covered with brush and subject to overflow at high stages. 

Control composed of gravel and cobbles; may shift at high stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 4.05 feet at 9 

a. m. June 15 (discharge, 1,620 second^feet); minimum stage, from water-stage 

recorder, 1.33 fejet 1 a. m. to 6 a. m. September 5 (discharge, 96 second-feet). 

: 1904-7-1920: Maximum stage recorded (not including period of no record, see 

records available), 6.28 feet June'20,1911 (discharge, 3,420 second-feet); minimum stage, 1.9 feet April 2, 1909 (discharge, 35 second-feet).

I <}E. Stage-discharge relation seriously affected by ice. , .?

second-feet, diverts about 100 yards above cable; flow in ditch is added to measured discharge at cable to obtain total flow past gage.

REGULATION. None except that due to diversions.

ACCURACY. Stage-discharge relation practically permanent during period of record. 

Rating curve well defined between SO and 1,000 second-feet. Staff gage read to 

hundredths twice daily May 11 to June 16; mean daily g/ige height thereafter 

obtained from water-stage recorder graph. Daily discharge ascertained by applying to rating table the mean daily gage height obtained by inspection of recorder 

graph or by averaging the two daily staff gage readings, except as indicated in 

footnote to table of daily discharge. Records good.

GAGE. Friez water-stage recorder on right bank 100 feet below highway bridge; 

referred to inside and outside staff gages; inspected by Edward Mulligan.

DISCHARGE MEASUREMENTS. Made from highway bridge or wading.

CHANNEL AND CONTROL. Bed composed of sand and gravel; fairly permanent. 

One channel at all stages. Control for low stages, gravel and cobble riffle; for 

high stages, log diversion dam a short distance below low-water control.

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

recorder, 3.30 feet at noon June 30 (discharge, 714 second-feet); stream reported 

dry July 27 to September 30.

DIVERSIONS. Several diversions for irrigation above. Station located near head of 

Chilly dry beds or "sinks." Usually about August 1 the stream becomes dry at 

this point owing to excessive losses in stream bed and to diversions above.

REGULATION. None, except that due to diversions.

ACCURACY. Stage-discharge relation changed July 16 by construction of small diversion dam below gage. Two poorly defined rating curves used, one applicable 

June 24 to July 15^ the other July 16 to September 30. Operation of water-stage 

recorder was not entirely satisfactory. Daily discharge ascertained by applying 

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

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

in footnote to table of daily discharge, except for period May 21 to June 19,1920, 

for which it was ascertained by theindirect method for shifting control, and except 

for period of ice effect, for which it was ascertained by means of three discharge 

measurements. Records good, except for periods during which ice effect or 

overflow occurred, for which they are fair. 

COOPERATION. Gage height record and numerous discharge measurements furnished

by Utah Construction Co.

The record at thia 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 the entire surface flow at this point into Mackay 

reservoir located a short distance below. For record at station on west channel of river 

and on east and west channels of Warm Spring Creek see pages 123, 137, and 140r 

respectively. For combined flow of both channels of Big Lost River and both channels of Warm Spring Creek see page 125. '

MACKAY RESERVOIR NEAR MACKAY, IDAHO,

LOCATION, In sec. 12, T. 7 N., E. 23 E., 4 miles northwest of Mackay, Ouster County.

RECORDS AY ARABLE,; January 1, 1919, to September 30, 1920. Kecords obtained 

by Utah Construction Co. prior to January 1^ 1919, but were not published by 

United States Geological Survey.

GAGE. Vertical staff on headgate tower near right end of dam; read to tenths once 

daily by employee of Utah Construction Co.

EXTREMES OF CONTENTS. Maximum stage recorded during year ending September 

30, 1919, 50.2 feet April 21 to May 2 (contents, 24,890 acre-feet); minimum contents, water surface below bottom of outlet tunnel, August 1 to September 30 

(maximum stage during this period, 6.9 feet August 1; minimum stage, 6.6 feet 

August 24 to September 2).

Maximum stage recorded during year ending September 30, 1920, 35.3 feet 

May 12 and 14 (contents, 12,240 acre-feet); minimum contents, water surface 

below bottom of outlet tunnel, October 1-19, August 5, 17-27, 31, and Septeto* 

ber 1-5, 12c44, and 18 (maximum stage during these periods 7.0 feet October 14- 

19, August 17, 18, 20-22, 26, 27, and September 12-14, and 18; minimum stage, 

6.75 feet October 1 and 2).

CooPEEATioN.'^-Gage-height record furnished by Utah Construction Co.

Stored water from this reaervoir is used for irrigation of land in the vicinity of Arcb, 

under the Utah Construction Co.'s Carey Act project. About 7,000 acres are under 

cultivation at present, but this area is subject to change from year to year. The reservoir is formed by a gravity earth dam 750 feet in length at crest. The crest is 75 feet 

above bottom of concrete core wall below which there is 15 feet of sheet piling to prevent excessive seepage. Crest of spillway is 10 feet below crest of dam, and 55 feet 

above bottom of outlet tunnel. Elevation of bottom of outlet tunnel corresponds to 

7.0-feet on gage, at which stage the usable storage is zero, although there is about 125 

acre-feet of water in the reservoir, which is not available for use. Elevation of crest 

of spillway corresponds to 62.0 feet on gage, at which stage the capacity of the reser-
EWER

voiria 38,400 acre-fetrfcy about 2,400 *cres of land being submerged. As tfce foundation 

of the dam is located on very porous material and* the core wall does not penetrate to 

bedrock, heavy seepage loss occurs, and at times during low water the inflow is not 

sufficient to counteract this loss plus the loss sustained by evaporation. Thus the 

stage of water in the reservoir occasionally falls below the bottom of the outlet tunnel. 

A study of the stream-flow records at this point indicates that most of the seepage 

from the reservoir reappears in the river channel above the gaging station at the 

"Narrows" 1J miles downstream, where favorable rock structure forces underground 

water to the surface. Additional water also reappears, part of which is probably side 

drainage while part evidently flows underground at the places where the surface flow 

into the reservoir is measured and thence through the reservoir. Seepage loss will 

probably diminish as silting takes place, although the amount of water thus lost has 

not varied appreciably in the last few years.

ACCURACY. Stage-discharge relation permanent during 1919; changed slightly 

several times during 1920. Two well-defined rating curves used; one was used 

direct January 1 to September 30 and December 16-30, 1919, and July 23 to 

August 15, 1920; the other was used direct October 11 to November 11, 1919, 

March 1 to June 5, June 18 to July 16 and August 19 to September 5, 1920; shifting-control method based on several discharge measurements, used for other 

periods. Operation of water-stage recorders satisfactory. Daily discharge ascertained by applying to rating table mean daily gage height obtained by inspecting 

recorder graph, except for periods for which shifting-control method was used 

and except as indicated in footnote to tables of'daily discharge. Records good 

except during periods January to March and August, 1919.

on basis of form of subsequent curve; the second, applicable May 12 to September 

30, 1920, is well defined between 70 and 700 second-feet; curves were used direct 

except for period May 12-31 for which the shifting-control method was used. 

Staff gage read to hundredths at least once daily prior to May 19, 1920; thereafter 

gage-height record was obtained from water-stage recorder, which operated satisfactorily. Daily discharge ascertained by applying to rating table title daily gage 

height from staff gage or the mean daily gage height obtained by inspection of 

recorder graph, except for periods for which the shifting-control method was used 

and except as indicated in footnote to tables of daily discharge. Records prior to 

June, 1920, fair; subsequent records good.

RECORDS AVAILABLE. May 1,1919, to September 30,1920. 

GAGE. Vertical staff on right bank; read by employees of Utah Construction Co.

Prior to May 3,1920, a vertical staff on right bank 100 feet above present gage and

at about same datum was used. 

DISCHARGE MEASUREMENTS. Made by wading or from suspension bridge 125 feet

above gage. 

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

stages. Banks steep and covered with brush. Channel congested by growth of

moss during summer. 

EXTREMES ' OF DISCHARGE. Maximum stage recorded during year ending September ,

30, 1919, 2.29 feet May 29 (discharge, 77 second-feet); minimum discharge, 9

REGULATION. None except that due to diversions.

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

banks. Two standard rating curves used, both fairly well defined, the first 

applicable prior to May 3, 1920, when new gage was installed, and the second 

applicable thereafter; curves used direct March 1-31, May 1 to June 16 and August 

2-24,1920; indirect method for shifting control used for other periods. Gage read 

to hundredths several times a week. Daily discharge ascertained by applying 

daily gage height to rating table except for periods for which the shiftingcontrol method was used and except as indicated in footnote to tables of daily 

discharge. Records good for 1919; fair for 1920.

COOPERATION. Gage-height record and several discharge measurements furnished 

by Utah Construction Co. and 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 stations 

on west channel of Warm Spring Creek and east and west channels of Big Lost River 

see pages 140,121, and 123, respectively. For record of combined flow of both channels of Big Lost River and Warm Spring Creek see page 125.

Juae 15, 1920, and September 14-30, 1920; indirect method for shifting control 

used for .intervening periods. Operation of water-stage recorder satisfactory. 

Daily discharge ascertained by applying1 to rating table mean daily gage heigitt 

obtained by inspection oi recorder graph except for .periods for which the shiftingcontrol method was used and except as indicated;in footnote to tables ofdafly 

discharge. Records good -except for high stages, for which they are fair.

COOPERATION. Gage-height record and several discharge measurements furnished 

by Utah Construction Co..

The record at this station represents a portion Of the ttaturfcl 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 Big Lost River will show practically the entire 

surface flow of Big Lost River, which enters Macfeay reservoir a short distance below\ 

For record from stations on east channel oiWarm Spring Creek and on east and west 

channels of Big Lost River see pages 137,121, and 123, respectively. For record of combined flow of both channels of Big Lost River and Warm Spripg Creek see page 125. c

144 SUKFACE WATEB, SUPPLY, 1919-1920, PART XII B.

CEDAR CREEK BELOW POWER PLANT, NEAR MACKAY, IDAHO.

LOCATION. In sec. 2, T. 7 N., R. 24 E., 75 feet below power house of Maekay Light 

& Power Co., immediately below diversion dam of Clark ditch, and 4 miles northeast of Mackay, Custer County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 1 to September 30, 1920. Records from October 20, 

1911, to March 31, 1913, are available for station 500 feet below the forks, and 

about 1 mile above present station.

GAGE. Vertical staff on left bank 10 feet below diversion dam of Clark ditch; read 

by power plant attendant.

DISCHARGE MEASUREMENTS. Made by wading.

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

and rock; fairly permanent. Control of same material; at times affected by de*bris.

EXTREMES OP DISCHARGE. Maximum stage recorded during period, 1.52 feet June 22 

(discharge, 90 second-feet); minimum stage, 0.18 foot May 7 (discharge, 0.5 secondfoot).

DIVERSIONS. Clark ditch diverts a short distance above gage. To determine total 

flow of Cedar Creek the flow in Clark ditch should be included. Mackay Light 

& Power Co. diverts water for power purposes about 1 mile upstream, but water 

is returned to stream a short distance above gage.

REGULATION. Slight diurnal fluctuation during low-water periods owing to impounding of water 1 mile upstream at power diversion dam and release through 

dam. Same regulation due to diversions by Clark ditch.

ACCURACY. Stage-discharge relation not permanent. Two rating curves used, the 

first, applicable May 1-21, fairly well defined, the second, applicable May 31 to 

September 30, well defined between 1 and 80 second-feet; curves used direct 

May 1-21 and May 31 to September 5; indirect method for shifting control used for 

remaining periods. Gage read to hundredths twice daily. Daily discharge 

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

for which the shifting control method was used and except as indicated in lootnote to table of daily discharge. Records good except for May, for which they are 

fair.

COOPERATION. Gage-height record and numerous discharge measurements furnished 

by water commissioner for Big Lost River.

1918, to March 19,1919, and August 17,1919, to March 18,1920, when it was rea4 

about three times weekly. Daily discharge ascertained by applying daily gage 

height to rating table except for days of no gage reading for which it was interpolated, and except for periods during which stage-discharge relation .was affected 

by ice for which it was ascertained by means of occasional gage readings, one discharge measurement, observer's notes, weather records, and comparison with flow

, at Topaz. Open-water records good; winter records fair*

ACCURACY. Stage-discharge relation changed slightly during period July 3-5, 1919, 

when canal was dry, and again during winter of 1919-20. Fairly well denned 

nting curve used April 29 to July 2, 1919; parallel curve used for remainder of 

season. Well-defined curve used during 1920. Gage read to hundredths twice 

t aily April 8 to September 5, 1920, and once daily during remaining periods of 

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

to rating table except as noted in footnote to daily-discharge tables. Records 

good for 1919; excellent for 1920.

3,170 second-feet); canal dry on many dates when headgates were closed.

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

DIVERSIONS. None between gage and headgates and none for some distance below 

giige. Surplus water may be discharged into river through waste g&tes about 200 

feet below headgates.

REGULATION. Flow regulated by head and waste gates.

ACCUHACY. Stage-discharge relation not permanent, owning largely to growth of 

aquatic plants; not affected by ice. Two standard rating curves used; one, 

applicable October 1, 1918, to September 21,1919, well defined; the other, applicable October 20, 1919, to September 19,1920, well defined above 1,200 second-

RI7EB BASIN.

BIG WOOD BT7ER BELOW MAGIC DAM, JSTEAR BJCHFIKLD, IDAHO. ,

LOCATION. In sec. 18, T. 2 S,». B. 18 is,, Blaine County, half»a mile below Magic 

dam of Idaho Irrigation Co. and 18 miles northwest of Richfield, Lincoln County. 

No tributaries between dam and station.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 19, 1911, to September 30, 1920.

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

former Lallie recorder; inspected by employees of Idaho Irrigation Co. DatuiQ 

presumably unchanged since establishment of station. *

DISCHARGE MEASUREMENTS. Made from cable 10 feet above gage or by wading.

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

and small boulders; somewhat shifting.

EXTREMES OP PISCHARGE. Maximum stage during year ending September 30,1919, 

from water-stage recorder, 5.13 feet May 25 and 26 (discharge, 1,570 second-feet); 

minimum discharge estimated 6 second-feet March 25 to April 3 (represents 

, leakage through gates and dam when gates were closed).

Maximum stage during year ending September 30, 1920, from water-stage 

recorder, 5J57 feet at 8 a. m. May 27 (discharge, 1,780 second-feet); minimum 

stage, 1.17 feet February 8-10 (discharge, 1.6 second-feet).

1911-192Q: Maximum stage recorded, 9.2 feet May 18, 1911 (discharge, 5,070 

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

ICE. Stage-discharge relation seldom affected by ice.

DIVERSIONS. No diversions made by Idaho Irrigation Co. immediately above station, 

but numerous ranch diversions are made in the upper drainage, the largest quantity of water probably being used in the district around Bailey. Flood waters 

are stored in Magic reservoir just above station and the first diversion by the 

company is Richfield canal, about 2 miles below.

REGULATION. Flow past station completely regulated by gates in outlet tunnel at 

Magic dam.

ACCURACY. ^Stage-discharge relation for high stages changed slightly during high 

water of May, 1920; slightly affected by ice during winter of 1919-20. Two 

rating curves used, both well defined below 1,600 second-feet, one applicable 

October 1, 1918, to September 30, 1919, and the other which is practically the 

same below 400 second-feet, applicable October 1, 1919, to September 30, 1920. 

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

applying to rating table mean daily gage height obtained by inspecting recorder 

graph except as indicated in footnote to tables of daily discharge. Open-water 

records good prior to April 6, 1JSL9, and excellent thereafter; winter records good.

COOPERATION. Gage-height recora and several discharge measurements furnished 

by Idaho Irrigation Co.

Discharge measurements of Big Wood River below Magic dam, near Richfield, Idaho, 

during the years ending Sept. SO, 1919 and 1920.

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

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

canal, 13 miles northeast of Shoshone, Lincoln County, and 14 miles below Magic 

dam.

DRAIN AGE AREA. Not measured.

KECORDS AVAILABLE. January 1, 1911, to September 30, 1920.

GAGE. Gurley 7-day water-stage recorder on right bank at same site as vertical staff 

gage which had been used since July 8,1918; installed in temporary shelter July 

5,1520, and referred to the staff gage; on September 25,1920, a permanent concrete 

shelter at same site was completed in which the recorder was installed, and a new 

outside staff gage was constructed (at same datum as previous staff gage) to which 

the recorder is referred. Prior to July 8, 1918, a vertical staff gage on left bank 

opposite present gage was used until about May 14, 1917, when it was destroyed 

by high water. A temporary vertical staff gage was installed May 15, 1917, at 

same location ,but at a datum 7.51 feet higher and was used until July 9, 1917. 

Thereafter until July 8, 1918, a new permanent staff gage was used; at same location and datum as gage used prior to about May 14,1917. All gage readings made 

on temporary staff gage were corrected to former datum. Gage datum raised 6.06 

feet July 8, 1918. Employee of Idaho Irrigation Co. acts as observer.

DISCHARGE MEASUREMENTS. Made from cable about 100 feet below gage or by 

wading.

CHANNEL AND CONTROL. Channel cut in lava rock. Stream bed rough. Control 

practically permanent. Measuring conditions are unfavorable on account of: 

rough cross section and irregular velocities.
190 STTBFACE WATBB PART XII B,

EXTREMES OF DISCHARGE, Maximum stage recorded during year emdiog !Septei»l«!r 

30,1919, 3.18 feet May 25 (discharge, 205 second-feet); stream reported dry July 

27 to August 9.

Maximum stage recorded during year ending September 30, 1920, 4.24 feet at 

6.30 p. m. June 12 (discharge, 394 second-feet); stream,reported dry April 1 to 

 May J7, June 7-10, June 26 to July 4, July 18 to August 4, and August 13 to September 28.

1911-1920: Maximum stage recorded, 15.0 feet (old datum) May 18, 1911 {discharge, 3,180 second-feet); no flow occurred during several different periods 

since establishment of station.

ICE.-^-Ice forms at gage but not at control; observations discontinued during wintes.

DIVERSIONS. Station below all divisions of Idaho Irrigation Co. North Gooding and 

Richfield canals divert between station and Magic dam.

REGULATION. Flow past station is regulated by operation of gates at Magic dam aad 

headgates of North Gooding and Richfield canals.

ACCURACY. Stage-discharge relation practically permanent. Two rating curves 

used; one, applicable April 20 to August 13, 1919, well denned between 50 and 

275 second-feet, fairly well defined above 275 second-feet, and poorly defined 

below 50 second-feet; the other, applicable April 1 to September 30, 1920, is a 

revision of the previous curve below 70 second-feet baaed on later discharge meaaurementsand is well defined below 275 second-feet and fairly well defined above 

that point. Gage read to hundredths twice daily prior to July 5,1920; thereafter 

mean daily gage height was obtained from water-stage recorder. Daily discharge 

ascertained by applying mean daily gage height to rating table except as indicated 

in footnote to tables of daily discharge. Records good except for low stages during 

1919.

COOPERATION. Gage-height record and several discharge measurements furnished fey

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

Banks covered with brush and subject to overflow. Control formed by a woodstave water pipe laid in bed of stream about 15 feet below gage.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 2.10 feet at noon August 9 (discharge, 166 second-feet); minimuia discharge, 0.9 second-foot March 21-24.

Maximum stage recorded during year ending September 30, 1920, 2.20 feet 

December 13 (discharge, 196 second-feet); minimum stage, 0.70 foot December 7 

(discharge, 3.0 second-feet).

1915-1920: Maximum stage recorded, 2.62 feet May 7, 1917 (discharge, 244 second-feet); minitaum discharge, 0.9 second-foot March 21-24,1919.

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

DIVERSIONS. None.

BE<HJLATION. The amount of water passing gage is affected by load at power plant 

half a mile upstream, and there is considerable diurnal fluctuation. The main 

river 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 not permanent; affected by ice December 21»

1918. to January 9, 1919. Used three rating curves as follows: October 1 to De" 

cember 20, 1918, well defined between 10 and 180 second-feet; January 10 to 

December 13,1919, well defined between 5 and 140 second-feet; and December 16,

1919. to September 30, 1920, fairly well defined between 5 and 170 second-feet. 

Gage read to hundredths once daily. Daily discharge ascertained by applying 

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

discharge and except for period during which stage-discharge relation was affected 

by ice for which mean discharge was ascertained by means of gage heights, weather 

records, and comparison- with flow of main river. Records fair prior to February 

1, 1919, thereafter good, except for possible inaccuracies due to breaks in gageheight record.

COOPERATION. Gage-height record furnished by Idaho Irrigation Co. Several discharge measurements furnished by Idaho Irrigation Co. and the water master for 

Big Wood and Little Wood rivers.

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

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

of the natural flow of Big Wood River and taken in conjunction with the record at the 

near-by station on the main river, will show the entire flow of the river at this point. 

For record from station on the main river see page 180. For record of combined flow 

of Big Wood River and Big Wood Slough see page 181.

CAM AS CREEK NEAR BLAINE, IDAHO.

LOCATION. In sec. 15, T. 1 S., R. 16 E., 500 feet below sheep bridge, a quarter of a 

mile north of Macon siding on Hill City branch of Oregon Short Line Railroad, 

1| miles below railroad bridge, 2J miles above backwater of Magic reservoir, and 

4 miles southeast of Blaine, Camas County. No tributaries or diversions between 

station and Magic reservoir.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 9, 1912, to September 30, 1920. Results of discharge 

measurements made in 1911 by Idaho Irrigation Co. are also available.

GAGE. Gurley water-stage recorder on left bank; installed June 1, 1916, to replace 

Lallie water-stage recorder at same location which had been used prior to that 

date. Location and datum of gage unchanged since 1912. Gage inspected by 

employees of Idaho Irrigation Co.

DISCHARGE MEASUREMENTS. Made from sheep bridge or by wading. ,

CHANNEL AND CONTROL. One channel at all stages. Bed of stream rocky, but control

somewhat shifting.

i EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 5.44 feet April 29 (measured discharge, 858 second-feet); minimum 

discharge, 2.4 second-feet August 14 and 24-28; probably not actual extremes for 

the year.

Maximum stage during year ending September 30, 1920, from water-stage recorder, 3.81 feet at 11.15 a. m. April 12 (discharge, 410 second-feet); minimum 

stage, 0.89 foot 4 p. m. to 6 p. m. August 17 (discharge, 2.3 second-feet); probably 

not actual extremes for the year.

1911-1920: Maximum stage recorded, 10.76 feet April 12, 1916 (measured discharge, 5,240 second-feet); minimum stage, 0.89 foot 4 p. m. to 6 p. m. August 17, 

1920.(discharge, 2.3 second-feet); probably not actual extremes. «
SNAKE RIVER BASIN. 201

ICE. Observations discontinued during winter.

DIVERSIONS. Many small diversions are made above station, but no data are available 

concerning them.

KEGULATION. None.

ACCURACY. Stage-discharge relation not permanent; changed during winter of 1919-20. 

Two rating curves used as follows: May 20 to October 8,1919, well defined between 

2 and 900 second-feet; April 5 to September 30,1920, well defined between 2 and 

250 second-feet. Operation of water-stage recorder satisfactory except at extremely low stages. Daily discharge ascertained by applying to rating table mean 

daily gage height obtained by inspection of recorder graph, except as indicated 

in footnote to table of daily discharge. Records good.

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

Idaho Irrigation Co.

1920. Two rating curves used as follows: April 21 to August 12, 1919, well 

defined between 11 and 300 second-feet; April 14 to September 30; 1920, well defined between 15 and 225 second-feet. Latter curve was used direct April 14 to July 

25; indirect method for shifting control used July 26 to September 30. Gage read 

to hundredths once daily during 1919; gage height obtained from water-stage 

recorder during 1920. Daily discharge ascertained by applying to rating table 

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

graph, except for periods for which shifting-control method was used and except 

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

FISH CREEK NEAR CARET, IDAHO.

LOCATION^ In sec. 15, T. 1 N., R. 22 E., at dam of Atlas Development Co., 12 miles 

northeast of Carey, Blaine County.

DRAINAGE AREA. Not measured:

RECORDS AVAILABLE. April 10, 1919, to September 30,1920.

GAGE. Staff gage in recording gage float well, on left side, near lower end of outlet 

channel of multiple arch dam; used January 21 to September 150, 1920. Gage is 

set to read the head on an 18-foot concrete Cippoletti control-weir located at end 

of outlet channel. Prior to January 21, 1920, records were obtained at a site 

about 1,000 feet below dam. The gage at lower location was set to read the head 

on a 12-foot wooden Cippoletti control-weir located a short distance below gage. 

Gage read by employees of Atlas Development Co. Stevens 8-day waterstage recorder at lower site April 10, 1919, to January 20, 1920, and at upper 

site January 21 to May 3, 1920, but operated only April 10 to December 28, 

1919.

DISCHARGE MEASUREMENTS. Made from footbridge or by wading.

CHANNEL AND CONTROL. Control formed by 18-foot concrete Cippoletti weir; stage 

of zero flow at gage height 0.0 foot. The control at site 1,000 feet below dam was 

a 12-foot wooden Cippoletti weir; stage of zero flow at gage height 0.03 foot.,

EXTREMES OP DISQHARGE. Maximum stage recorded during year ending September 

30,1919,1.70 feet at 2 p. m. April 26 (discharge, 101 second-feet); minimum stage, 

0.20 foot August 5 and 6 (discharge, 2.8 second-feet).

Maximum stage recorded during year ending September 30, 1920, 0.98 foot at 

5.30 p. m. May 14 (discharge, 65 second-feet); minimum discharge, 1.5 secondfeet February 15-22 (flow interpolated February 17-21, when a lower discharge 

may have occurred).

ICE. Stage-discharge relation not affected by ice presumably due to proximity of 

station to reservoir.

DIVERSIONS. 'None between this station and the one above dam.

[REGULATION. Flow regulated by headgates at dam above.

ACCURACY. Stage-discharge relation practically permanent for both gage locations. 

Two rating curves used as follows: April 10, 1919, to January 20, 1920, for lower 

gage, fairly well denned below 95 second-feet; January 21 to September 30,1920, 

fairly well defined below 80 second-feet. Operation of water-stage recorder rather 

unsatisfactory prior to December 29, 1919; after that date staff gage was read to 

hundredths twice daily. Daily discharge ascertained by applying to rating table 

mean daily gage height obtained by inspection of recorder graph or by averaging the two daily readings except as indicated in footnote to table of daily dis- 

, charge. Records good. i

COOPERATION. Gage-height record furnished by Atlas Development Co.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. Numerous diversions for irrigation above.

REGULATION. None.

ACCURACY. Stage-discharge relation changed several times owing to light aquatic 

growth below gage. Rating curve well defined between 20 and 140 second-feet; 

used direct May 25 to June 14, July 1-7, and August 15 to September 30; indirect 

method for shifting control used for intervening periods. Operations of waterstage recorder satisfactory. Daily discharge ascertained by applying to rating 

table mean daily gage height obtained by inspection of recorder graph, or,> for 

days of considerable fluctuation, by averaging the discharge obtained by applying to rating table the gage height for hourly or other regular intervals, except as 

indicated in footnote to table of daily discharge. Records of the actual flow in 

channel past gage, good. Part of the time, however, some additional flow was 

diverted around gage on right bank through a small slough which heads about 300 

feet above gage. Prior to August 1 the amount of this additional flow is unknown; 

but from August 1 to September 30 a fairly accurate record of the flow was obtained 

which is covered in footnote to table of monthly discharge.

NOTE. See footnote to daily-discharge tables.

OWYHEE RIVER NEAR GOLD CREEK, KEY.

LOCATION. In W. \ sec. 24, T. 44 N., R. 54 E., an eighth of a mile below Wild 

Horse dam site, 9 miles west of Gold Creek, Elko County, and 65 miles north of 

Elko.

DRAINAGE AREA. 209 square miles (measured on map compiled by Irrigation Service 

of United States Indian Office).

RECORDS AVAILABLE. March 26, 1916, to September 30,1920.

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

Johnson.

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

CHANNEL AND CONTROL. Bed composed of rocks and loose sand. Control is rock 

riffle in each of two channels where stream is divided by small island about 500 

feet below gage; subject to change by work of beavers. Left bank high and 

rocky; right bank overflowed at extreme high stages; dense growth of willows 

along banks.

EXTREMES OF DISCHARGE. Maximum and minimum stages not determined for year 

ending September 30, 1919.

Maximum stage during year ending September 30,1920, 6.0 feet about April 30, 

determined on May 5 from high-water mark (discharge, 623 second-feet); minimum discharge recorded, 1.8 second-feet September 10, by current-meter measurement.

1916-1920: Maximum stage recorded from water-stage recorder, 8.5 feet at 3 

a. m. May 14, 1917 (discharge, from extension of rating curve, 1,380 second-feet); 

minimum discharge, probably less than 1 second-foot in August, 1918.

ICE. River freezes every winter; observations discontinued.

DIVERSIONS. Wild hay meadows above station irrigated during flood season.

REGULATION. None.

ACCURACY. Stage-discharge relation permanent except as affected by backwater from 

beaver dams. Standard rating curve well defined below 450 second-feet; used 

direct except for periods of backwater effect from beaver dams, as indicated in 

footnote to tables of daily discharge. Operation of water-stage recorder unsatisfactory at times. Daily discharge ascertained by applying to rating table mean 

daily gage height obtained by inspection of recorder graph except as indicated
216 WATER SUPPLY, 1919-1920, PABT XII B.

in footnote to daily discharge tables. Estimates of mean monthly discharge, 

indicated in footnote to daily discharge tables, obtained by means of eight 

discharge measurements and comparison with flow at station near Owyhee, Nev. 

Records good for periods during which recorder was operating and channel 

was unobstructed; fair for periods of^obstructed channel; estimates of monthly 

discharge roughly approximate.

ACCURACY. Stage-discharge relation changed slightly below 125 second-feet follbwing the high water of April and May, 1919; changed back to old rating during 

winter of 1919-20. Two rating curves used, both well defined below 1,500 secondfeet, one applicable for November, 1919, and the other applicable for remaining 

periods of record. Operation of water-stage recorder unsatisfactory except during 

periods October 1 to November 4, 1918, March 24 to May 29, and November 3 to 

December 9,1919, December 25,1919, to January 28,1920, and April 20 to June 11, 

1920. Daily discharge for periods during which recorder was operating ascertained by applying to rating table mean daily gage height obtained by inspection 

oi recorder graph except as indicated in footnote to daily-discharge tables. Estimates of mean monthly discharge during 1919, indicated in footnote to table of 

daily discharge, obtained by means of two discharge measurements and comparison with flow at station near Gold Creek. Records good for periods during 

which recorder was operating; estimates of monthly discharge roughly approximate*

RECORDS AVAILABLE. March 21, 1911, to September 30, 1920.

GAGE. Friez water-stage recorder on right bank; installed April 4, 1915, to replace 

inclined staff at same location and datum; inspected by Roy Call.

DISCHARGE MEASUREMENTS. Made from cable 50 feet above gage or by wading.
SNAKE BIVER. BASIN. 38*

CHANNEL AND OONTBOL. Bed composed of gravel and boulders, Conteol practically 

permanent, except under unusually severe ice or flood conditions. Banks not 

overflowed. One channel at all stages.

EXTBEMES OF BISCHABKJE.' Maximum stage during year ending September 30,1919, 

from water-stage recorder, 7.5 feet at 4 p. m. May 29 (discharge, 8,790 second-feet); 

minimum stage, 1.94 feet at 8 p. m. September 16 (discharge, 244 second-feet); 

lower flow may have occurred during winter. j 

Maximum stftge during year ending September 30, 1920, from water-stage 

recorder, 6.04 feet at 1 a. m. May 17 (discharge, 5,840 second-feet); minimum 

stage, 1.83 feet at noon February 3 (dischafge, 186 second-feet); lower flow may 

have occurred during winter.

1911-1920: Maximum stage recorded, 7.82 feet at 3 a. m. May 15,1917. ([discharge, 

9,430 second-feet); minimum stage, 1.73 feet at 10.30 p. m. November 13, 1916

IOB. Stage-discharge relation seriously affected by ice. "'

DIVERSIONS. No important diversions above station and none between it and the 

station at Bowling.

REGULATION. None.

ACCURACY. Stage-discharge relation, below 1^600 second-feet, changed by high 

water of May, 1919, and again slightly by the high water of May, 1920; affected by 

ice December 15,1918, to February 25, 1919, and November 26, 1919, to January 

26,1920. Three well-defined rating curves used, applicable respectively, October 

1,1918, to May 29,1919, May 30,1919, to May 17,1920, and May 18 to September 

30,1920; above 1,600 second-feet the curves are practically identical. Operation 

of water-stage recorder satisfactory, except during winter periods, when staff gage 

was read occasionally. Daily discharge ascertained by applying to rating table 

mean daily gage height obtained by inspection of recorder graph except as indicated in footnote to daily-discharge tables and except for periods of ice effect for 

which it was ascertained by means of occasional gage readings, observer's notes, 

and weather records. Open-water records good; winter records poor.

ARROWROCK RESERVOIR AT ARROWROCK, IDAHO.

LOCATION. In E. £ sec. 13, T. 3 N., R. 4 E., at Arrowrock, Boise County, 22 miles by

road east from Boise. 

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. October 1, 1917, to September 30, 1920. 

GAGE. Graduations painted on center of upstream vertical face of concrete dam in 

September, 1917; read usually to tenths once daily by E. L. Ballard, superintendent of Arrowrock dam. Vertical staff in seven sections on south side of 

reservoir immediately above dam used after storage in reservoir was initiated, 

with exception of few months in 19161, when chain gage on dam was used. Uncertainty in changes in staff gages caused by ice and frost action make publication of 

actual observations prior to use of present gage seem unwarranted. 

EXTREMES OP CONTENTS. Maximum stage recorded during year ending September 

30, 1919, 3,212.8 feet May 30 (contents, 281,900 acre-feet); natural flow passing 

through reservoir, September 13-17 and 20-30.

Maximum stage recorded during year ending September 30, 1920, 3,212.5 feet 

June 9 and 10 (contents, 281,000 acre-feet); natural flow passing through reservoir 

October 1 and September 13-30.

1917-1920: Maximum stage recorded, 3,214.1 feet June 14, 1918 (contents, 

285,800 acre-feet); natural flow passing through reservoir September 13-17, 20-30, 

and October 1,1919, and September 13-30, 1920. * 

COOPERATION. Gage-height record and table of storage capacity furnished by United

States Reclamation Service.

Stored water from this reservoir is used for irrigation of land in Boise Valley. The 

reservoir is formed by a concrete dam, gravity section, 348.5 feet high and 1,100 feet 

long at crest. Base of dam is 223 feet thick and thinnest point near the top is 15.5 

feet thick. A 16-foot roadway is carried across on top of the dam. A lip spillway at 

north end of dam has a carrying capacity of 40,000 second-feet. Elevation of spillway crest referred to gage datum is 3,205 feet, the capacity of the reservoir at tha,t

stage being 259,000 acre-feet. A movable crest is provided for $ie spillway, the top 

of which is at elevation 3,211 feet. The capacity of the reservoir at that stage is 276,500 

acre-feet, and about 2,900 acres of land ia submerged. Elevation of center line of 

sluice gates is 2,967 feet, the capacity of the reservoir at that stage being 131 acre-feet.

NOTE. Natural flow passing through reservoir Sept. 13-17,20-30, and Oct. 1,1919, and Sept. 13-30,1920
BIYEB BASIN;« -' -' ' -

BOJSE RIVBB. AT DOWLIHO'S RANCH, WEAR ARROWROCK, IDAHO.

LOCATION. In sec. 15, T. 3 N., R. 4 E., at Bowling's ranch, Elmore County, threefourths of a mile above Moore Creek, 2 miles below Highland power dam, and 4 

miles below Arrowrock, Boise County.

DRAINAGE ABBA. 2,230 square miles (measured on topographic maps).

RECORDS AVAILABLE. March 12,1911, to September 30,1920.

GAGE. Friez water-stage recorder on left bank; installed March 19, 1915, to replace 

an inclined staff set to same datum and at practically same location; inspected 

by J. N. Davis.

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

CHANNEL AND CONTROL. Bed of stream composed of gravel and boulders. One 

channel at all stages. Control shifts slightly.

EXTREMES OP DISCHARGE. Maximum stage during year ending September 30, 1919, 

from water-stage recorder, 8.26 feet at midnight May 29 (discharge, 13,600 secondfeet); minimum stage, 1.50 feet for several hours on March 24 and 25 (discharge 

104 second-feet).

Maximum stage during year ending September 30, 1920, from water-stage 

recorder, 6.25 feet for several hours on June 9 (discharge, 6,700 second-feet); 

minimum stage, 1.30 feet (staff gage reading) at 8 a. m. March 5 and 6 (discharge, 

70 second-feet); lower flow may have occurred on either of these days when water 

fell below intake pipe, owing to regulation at Arrowrock dam.

1911-1920: Maximum stage recorded, 8.7 feet June 13, 1911 (discharge, 15,100 

second-feet); minimum stage occurred December 15 and 28, 1917, when stage 

was below gage owing to closing of gates at Arrowrock dam (estimated discharge, 

20 second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. None of consequence above station. New York canal of Boise project, 

United States Reclamation Service, diverts 10 miles below and has a maximum 

capacity of about 2,500 second-feet. Several smaller canals, total capacity of 

2,900 second-feet, divert below New York canal.

REGULATION . Since February 21, 1915, flow has been regulated at Arrowrocfc 

reservoir, 4 miles upstream, which has storage capacity of about 280,000 acre-feet. 

Water is stored during winter and spring and released during irrigation season.

ACCURACY. Stage-discharge relation changed slightly during high water of May 29 

and 30, 1919; affected by ice during winter of 1919-20. Three rating curves 

used. From October 1, 1918, to May 29, 1919, the 1918 rating curve was used 

after applying a correction of +0.02 foot to recorded gage height on basis of 

measurements made during period March, 1918, to May, 1919; this is equivalent 

to using a curve parallel to the 1918 curve, and such a curve would be well defined. 

Curve used May 30,1919, to January 19,1920, well defined above 240 second-feet. 

Curve used January 20 to September 30,1920, well defined within limits of stage 

which occurred; differs from previous curve only in that it is better defined by 

later discharge measurements. Operation of water-stage recorder satisfactory, 

except during a few short periods in cold weather and except during extremely 

low stages; daily staff-gage readings were made when recorder was not operating. 

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

obtained by inspection of recorder graph, except for periods indicated in footnote 

to tables of daily discharge, except for period noted above, for which 1918 rating 

was applicable, and except for days of considerable fluctuation in stage for which 

it was ascertained by averaging the results obtained by applying to rating table 

the gage height for hourly or other regular intervals. Open-water records excellent, with the exception possibly of those for extremely low stages; records for 

periods of ice effect, fair to good.

COOPERATION. Several discharge measurements furnished by United States Reclamation Service and water master for Boise River.

high water of May 29 and 30, 1919; affected by ice during periods November to 

January, 1919 and 1920. Three well defined rating curves used, applicable 

October 1,1918, to May 29,1919, May 30,1919, to January 16,1920, and January 17 

to September 30,1920; curve used May 30,1919, to January 16,1920, is a revision 

of the previous curve below 700 second-feet; curve used January 17 to September 

30,1920, is a revision of previous curve above 600 second-feet, having been drawn 

so as to better average later discharge measurements. Operation of water-stage 

record unsatisfactory during 1919 and during cold weather; satisfactory during 

19201 DMly discharge ascertained by applying to rating table mean daily gage

! height obtained by inspection of recorder graph except for periods of ice effect 

and lor periods .during which recorder was not operating as indicated in footnote 

to tables of daily discharge. Open-water records excellent for 1919 and good for

; 1920; winter records good for 1919 and fair for 1920.

MOOBK GREEK KKAH AKROWROCK, U3AHO.

LOCATION. In sec. 21, T. 3 N., R. 4 E., a quarter of a mile above highway bridge 

on Boise- Arrowrock road, half a mile above mouth, and 5 miles southwest of 

Arrowtock, Boiee County.

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

RECORDS AVAILABLE. October 1, 1914> to September 30, 1920 (discharge measurements only prior to December 1, 1915). >

GAGE. ^Graduations to feet and tenths chiseled on face of rock ledge on left bank of 

stream and marked with white paint; read by A. P. Webb.

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

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

shifts frequently owing to deposition of sand at low stages and scouring out at 

high stages. Stream usually carries much sand and silt as a result of placer 

operations in Boise Basin. One channel at all stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 6.00 feet at 7.30 p. m. April 4 (discharge, about 2,800 second-feet); 

minimum stage recorded, 0.65 foot morning of August 30 (discharge, 20 secondfeet); actual minimum flow may have occurred during period of ice effect.

Maximum discharge during year ending September 30, 1920, 1,150 second-feet 

April 13 and May 10; minimum stage recorded, 0.60 foot August 17 and 21-23 

(discharge, 17 second-feet).

1915-1920: Maximum stage, 6.3 feet April 11, 1916 (discharge, 3,140 secondfeet); minimum stage, 0.60 foot August 17 and 21-23, 1920 (discharge, 17 secondfeet).

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

DIVERSIONS. No important diversions above station.

REGULATION. None.

ACCURACY. Stage-discharge relation practically permanent during 1919 except as 

affected by ice, but changed frequently during 1920; only slightly affected by 

ice during 1920. Standard rating curve well defined; used direct October 1, 1918, 

to October 22, 1919, February 28 to April 4, 1920, and July 21 to September 30, 

1920; indirect method for shifting control used for intervening periods. Gage 

read to half-tenths once daily during high water and to hundredths during low 

water; rough water at high stages makes it difficult to read gage with refinement. 

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

for periods for which the shilting-control method was used and except as indicated 

in footnote to tables of daily discharge. Records of daily discharge subject to 

error; records of monthly discharge, good.

COOPERATION. Several discharge measurements furnished by United States Reclamation Service and water master for Boise River.

Drewsey, Harney County, and 6 miles above limit of backwater of Warmsprings 

reservoir.

DRAINAGE ABBA. Not measured.

RECORDS AVAILABLE. June 1 to September 30, 1920. Records for station referred to 

by same name in Water-Supply-Paper 393 (p. 168) not comparable.

GAGE. Stevens 8-day water-stage recorder on left bank a quarter* of a mile below 

ranch house; installed July 14; inspected by Silas Tillotson. Staff gage read 

June 5 to July 13; readings corrected by 0.33 foot to reduce them to datum of 

recorder.

DISCHARGE MEASUREMENTS. Made by wading near gage.

CHANNEL AND CONTROL. Bed composed of gravel and sand; fairly permanent. One 

channel at all stages. '

EXTREMES OF DISCHARGE. Maximum stage recorded during period, 1.62 feet June 8 

and 10 (discharge, 128 second-feet); minimum stage, from water-stage recorder, 

0.62 foot August 17 (discharge, 2.6 second-feet).

ICE. No winter record.

DIVERSIONS. Large area irrigated above station. No diversion between station 

and Warmsprings reservoir, or around gage.

REGULATION. None.

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

defined between 2 and 20 second-feet; fairly well defined between 20 and 150 

second-feet. Gage read three times a week prior to July 5; operation of water-stage 

recorder satisfactory July 14 to September 30. Daily discharge ascertained by 

applying to rating table the daily gage height from staff gage and interpolating for 

days of missing gage height, or applying the mean daily gage height obtained by 

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

discharge. Records good.

COOPERATION. Field data furnished by H. G. Kennard, water master for Malheur 

County.

MALHETJR RIVER BELOW WARMSPRINGS RESERVOIR, HEAR RIVERSIDE, OREG.

LOCATION. In SW. J 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. From March 18, 1919, to April 27, 1920, station was 1 mile upstream, 

in SW. J sec. 8, T. 23 S., R. 37 E., 250 feet below dam.

DRAINAGE AREA. About 1,100 square miles.

RECORDS AVAILABLE. March 18,1919, to September 30,1920, from stations described 

above. December 9, 1914, to July 4, 1917, from station 500 feet above dam site. 

January 3, 1906, to March 31, 1907, and December 16, 1908, to December 31, 

1910, from station 4 miles below dam and 200 feet above South Fork.
248 SURFACE WATEB SUPPLY,, 1919-1920, PAET XII B.

At upper station, vertical staff on right bank; at low«r*Statiaft^«v»rti9iklstaff 

in 2 sections on left bank; read by TJ. S. Yoat. For description of gages at other 

locations see Water-Supply Papers 214, 252, 272, 292, 413, 443, and 463.

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

dam or by wading,

CHANNEL AND CONTROL. Bed composed of gravel and small stones; likely to shift 

in floods. One channel for medium and high stages at upper station, but during 

low stages water crosses riffle in two or more channels. At -lower station one 

channel at all stages. Concrete control installed April 27, 1920, about 2QQ feet 

below gage; permanent except for occasional deposition of debris.

EXTREMES OF DISCHARGE. Maximum stage recorded during period March 18, 1919, 

to September 30, 1920, 5.25 feet April 5, 1919 (discharge, 1,350 second-feet); 

minimum discharge, no flow, August 1 to Septernber 16 and September 18, 1919. 

1906-1910; 1915-1917j 1919-20: Maximum discharge recorded, 5,490 secondfeet Mar^h 2, l&W (gage height on Riverside gage, 10.7 feet); 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. ;

ICE. -No water released from dam during winter.

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

REGULATION. Flow past station entirely controlled by operation of gates in Warmsprings dam'since its completion on November 25, 1919.

ACCURACY. Stage-discharge relation changed several times during summer of 1919, 

when dam,was being constructed, owing to debris lodging on control; changed 

also on April 28, 1920, when gage was moved. Rating curve,used prior to May 

13, 1919, well defined above 300 second-feet; parallel curve used May 19 to June 

8, 1919; shifting-control method used May 14-18 and June 9. Curve used July 

30 to December 18, 1919, fairly well defined for range in stage which occurred. 

Curve used April 28 to September 30, 1920, well defined between 10 and 350 

second-feet. Gage read to huridredths once daily. Daily discharge ascertained 

by applying daily gage height to rating table except for periods for which shiftingcontrol method was used and except as indicated in footnote to table of daily 

discharge. Records good except those for period June to November, 1919, 

which are fair to poor.

COOPERATION. Gage-height record and most of discharge measurements furnished 

 by Warmsprings Irrigation District and water master.

MALHETTR RIVER NEAR NAMORF, OREG.

LOCATION. In SE. £ sec. 2, T. 21 S., R. 40 E., at F. J. Froman's ranch, 1 mile south 

of east portal of tunnel No. 1 oti Oregon & Eastern Railroad, 3 miles west of Namorf flag station, and 15 miles west of Harper post office, Malheur County. North 

Fork of Malheur River enters near Juntura, 20 miles above.

DRAINAGE AREA. 2,560 square miles (measured on General Land Office map).

RECORDS AVAILABLE. May 24, 1913, to September 30, 1920.

GAGE. Inclined staff on right bank, 300 feet above Froman's house; read by F. J. 

Froman. Datum raised 1.53 feet August 17, 1918.

DISCHARGE MEASUREMENTS. Made from flume 400 feet above gage or by wading.

CHANNEL AND CONTROL. Control, 400 feet below gage, composed of cobbles and 

coarse gravel; clean; shifts at high stages. Channel between control and gage 

and above gage is wide and current is sluggish.. One channel at all stages at 

gage. Stage of zero flow at gage height 0.46 foot, as determined October 31,1919.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 4.62 feet April 1 (discharge, 2,940 second-feet); minimum stage, 0.60 

foot July 25 (discharge, 4 second-feet).

Maximum stage recorded during year ending September 30, 1920, 8.0 feet at 

10 a. m. January 16 (discharge estimated, 2,500 second-feet; stage-discharge relation affected by an ice jam). Minimum stage occurred during period of ice effect 

discharge probably as low as 10 second-feet for a short time.

1913-1920: Maximum stage recorded, 10.7 feet February 6, 1916 (discharge 

not determined on account of ice jam); maximum open-water stage recorded, 9.1 

feet during night of February 7, 1916 (discharge, 8,450 second-feet); minimum 

stage, 0.60 foot July 25, 1919 (discharge, 4 second-feet). Highest stage in recent 

years 11.3 feet March 1,1910, determined by leveling to high-water marks pointed 

out by F. J. Froman June 4, 1918 (discharge from extension of rating curve, 

12,600 second-feet). Floods of March 7 and 9, 1894, are said to have been about 

0.3 foot higher.

ICE. Stage-discharge relation occasionally seriously affected by ice.
SHAKE BIVEE BASIN.

DIVERSIONS. ^Many small diversions from river and its tributaries above gage, t&e 

largest being near Drewsey and from North Fork near Beulah.

REGULATION.: Flow largely controlled at Warmsprings dam since November 25,1919. 

Capacity of Warmsprings reservoir, 170,000 acre-feet.

ACCURACY. -Stage-discharge relation changed during high water of latter part of 

March, 1919, during ice jam of January 16, 1920, when wire fence below gage 

was washed out, and on May 11, 1920, when wire fence was replaced; affected 

by ice November 29 and 30, and December 1, 20-22, and 29-31, 1918, January 

1-15, and November 26-28, 1919, and December 6, 1919, to January 16, 1920. 

Two well defined rating curves used, one applicable October 1, 1918, to March 

31, 1919, and January 17 to May 10, 1920, and the other applicable April 1,1919, 

to January 16,1920, and May 11 to September 30,1920. Gage read to hundredths 

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

table except for periods of ice effect for which it was ascertained by means of 

gage heights, observer's notes, and weather records and except as indicated in 

footnote to table of daily discharge. Open-water records good except those for 

July and August, 1919, which are poor; winter records subject to error.

PAYETTE RIVER HEAR HORSESHOE BEND, IDAHO.

LOCATION. In sec. 14, T. 7 N., R. 2 B., 100 feet east of tracks of Idaho Northern 

branch of Oregon Short Line Railroad and 1£ miles northeast of Horseshoe Bend, 

Boise County.

DRAINAGE AREA. 2,160 square miles measured on topographic and Land Office

RECORDS AVAILABLE. February 13, 1908, to September 30, 1916, and July 27, 1919, 

1919, to September 30, 1920. Prior to November 23, 1912, data refers to gage 

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

stations.

GAGE. Barrett and Lawrence water-stage recorder on right bank about 200 feet 

above railroad crossing installed May 3, 1912; inspected by S. H. McAlister. 

February 13, 1906, to November 22, 1912, inclined gage on right bank 2 miles 

above present gage.

DISCHARGE MEASUREMENTS. Made from cable 200 feet below gage.

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

with a few large rocks. Control practically permanent.

EXTREMES op DISCHARGE. Maximum stage during period July 27, 1919, to September 30, 1920, from water-stage recorder, 6.62 feet at 11 a. m. June 16 (discharge, 

11,600 second-feet); minimum stage, 0.79 foot November 28 (discharge, 550 

second-feet). Gage height, May 29, 1919, 8.04 feet; measured discharge, 16,500 

second-feet.

1906-1916; 1919-20: Maximum stage recorded, 9.45 feet at 6 a. m. June 20, 

1916 (discharge, 19,600 second-feet); minimum stage, 0.79 foot November 28, 

1919 (discharge, 550 second-feet).

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. A few small ranch diversions are made above station. Record represents practically total flow from upper Payette basin.

REGULATION. Flow during. July, August, and September partly regulated by 

installation and later gradual removal of temporary dam at outlet of Payette 

Lake, 70 miles above.

ACCURACY. Stage-discharge relation permanent except as affected by ice. Rating 

curve well defined between 630 and 15,000 second-feet. Operation of waterstage recorder satisfactory. Daily discharge ascertained by applying to rating 

table mean daily gage height obtained by inspection of recorder graph except 

as indicated in footnote to table of daily discharge. Open-water records good? 

' winter records fair.

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

NORTH FORK OF PAYETTE RIVER AT LARDO, IDAHO.

LOCATION. In sec. 8, T. 18 N., R. 3 E., a quarter of a mile below Lardo, Valley County, 

and outlet of Big Payette Lake. No tributaries enter between lake and gage.

DRAINAGE AREA. 131 square miles (measured on topographic and Land Office maps)-

RECORDS AVAILABLE. September 1,1908, to June 30,1917; May 24,1919, to September 30, 1920.

GAGE. Inclined staff on left bank, installed July 25,1911; read by Mark Cole, Alice 

Stiles, James Stiles, and Vernon Land. Original temporary gage, used September 

1 to October 8,1908, was located about 1 mile below site of present gage; permanent vertical staff gage used thereafter until July 25, 1911, was installed October 

14, 1908, on left bank about 30 feet below present site. Gage datum unchanged 

since October 14, 1908.

DISCHARGE MEASUREMENTS. Made from cable half a mile below gage or by wading.

CHANNEL AND CONTROL. Bed of stream and control composed of cobbles and gravel; 

slightly shifting.

EXTREMES OF DISCHARGE. Maximum stage recorded during period May 24, 1919, to 

September 30,1920, 6.7 feet June 10,1920 (discharge, 3,070 second-feet); minimum 

stage, 1.0 foot November 10-26, 1919 (discharge, 3 second-feet).

1908-1917; 1919-20: Maximum stage recorded, 7.5 feet June 5,1909 (discharge, 

4,250 second-feet); minimum discharge, 3 second-feet October 21 and 22, 1911, 

and November 10-26, 1919.

ICE. Stage-discharge relation not affected by ice, presumably because of proximity 

of station to Big Payette Lake. <

DIVERSIONS. None above station.

REGULATION^ Flow during July, August, and September partly regulated by 

installation and later gradual removal of temporary dam at outlet of Payette 

Lake, a quarter of a mile above.

ACCURACY. Stage-discharge* relation changed slightly in January, 1920. Rating 

curve used May 24, 1919, to January 15, 1920, well defined below 2,000 secondfeet; parallel curve used after January 15,1920, based on later discharge measurements. Gage read to half-tenths once daily; readings unreliable at times. Daily 

discharge ascertained by applying daily gage height to rating table except as 

indicated in footnote to table of daily discharge. Open-water records good; 

winter records fair.

NOTE. Figures for August and September, 1920, do not represent natural flow because dam at outlet of 

Payette Lake was out from Aug. 15 to Sept. 28. See footnote to daily-discharge tables.

NORTH FORK OF PAYETTE RIVER AT VAN WYCK, IDAHO.

LOCATION. In sec. 26, T. 14 N., R. 3 E., at highway bridge half a mile north of Van 

Wyck, Valley County, and 2 miles northwest of Cascade. Willow Creek, a small 

stream, enters from south half a mile below.

DRAINAGE AREA. 586 square miles (measured on topographic and Land Office maps).

RECORDS AVAILABLE. January 1, 1912, to June 30, 1916; June 9 to September 30, 

1920. Gage heights January 1 to August 7, 1912, were derived from private 

records from comparative gage readings; daily discharge not determined prior 

to June 20, 1912. Several discharge measurements were made during 1919 and 

spring of 1920.

GAGE. Vertical staff spiked to downstream side of second bridge pier from right end 

of bridge; read by Udell Witchey. Gage used August 8, 1912, to May 4, 1913, 

was a vertical staff at same location, reading 0.6 foot higher than present gage.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Bed composed of rock overlain with sand and gravel. 

Control somewhat shifting.

EXTREMES OP DISCHARGE. Maximum stage recorded during period, June 9 to September 30, 1920, 6.65 feet June 13 (discharge, 4,750 second-feet); minimum stage, 

1.70 feet August 20 and 21 (discharge, 128 second-feet).

1912-1916; 1920: Maximum stage recorded, 9.1 feet June 1 and 2,1913 (discharge, 

8,140 second-feet); minimum stage occurred August 20 and 21, 1920.

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

DIVERSIONS. None of consequence above station.

REGULATION. Flow during July, August, and September partly regulated by installation and later gradual removal of temporary dam at outlet of Payette 

Lake, 30 miles above.

ACCURACY. Stage-discharge relation practically permanent during period. Rating 

curve fairly well defined between 140 and 4,300 second-feet. Gage read to halftenths once daily. Daily discharge ascertained by applying daily gage height 

to rating table and interpolating for days of no record. Records fail.

below gage or by wading.

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

with brush; left bank not likely to be overflowed; right bank subject to overflow 

at extremely high stages. Control formed by poorly-defined gravel riffle and by 

log embedded in stream bed below gage; affected at times by debris.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 5.7 feet May 19? 

(discharge, 584 second-feet); minimum stage, 2.3 feet November 12 (discharge, 

3 second-feet); lower flow may have occurred during period of ice effect.

1910-1913: Maximum stage recorded, 5.4 feet April 29 and 30, 1912 (discharges, 

512 second-feet); minimum stage, 2.0 feet July 23-27,1911 (discharge, 0.5 secondfoot.)

ICE. Stage-discharge relation seriously affected by ice.

DIVERSIONS. Several small ditches divert above and below station.

REGULATION. Flow regulated by headgates at Lost Greek reservoir about 12 miles 

above. Headgates changed only occasionally.

ACCURACY. Stage-discharge relation practically permanent, except as affected by 

ice November 29 to February 9. Rating curve fairly well defined between 3 and 

260 second-feet. Gage read to hundredths once daily. Daily discharge ascertained by applying daily gage height to rating table, except for period during which 

stage-discharge relation was affected by ice for which it was ascertained by means 

of gage heights, one discharge measurement, observer's notes, and weather records. Records good.

SNAKE RIVER BASIKT,

EXTREMES OF DisesABGE^Maximum discharge during period of record* 183 secondfeet July 18, by current-meter measurement (gage-height indeterminate); minimum stage, from water-stage recorder, 1.75 feet August 28-31 (discharge, 5.6 

second-feet).

DIVERSIONS. Canal of, Crane Creek Irrigation District, which diverts about 4 miles 

above gage, is principal diversion. Several small ranch diversions a short distance

. Flow regulated by headgates at Crane Creek reservoir and by diverACCURACY. Stage-discharge relation permanent after August 21 when concrete 

control was completed; prior to that date numerous changes of control occurred 

as indicated by frequent discharge measurements. Standard rating curve used 

prior to August 21, fairly well defined; was used direct July 21, 27-31, August 1, 

4, and 11-14; indirect method for shifting control used for intervening periods 

except for July 14-20, 22, and August 15 and 19, for which results of discharge 

measurements were used. Curve used August 21 to September 15, well defined 

between 5 and 25 second-feet; was used direct throughout period. Operation of 

water-stage recorder fairly satisfactory. Daily discharge ascertained by applying 

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

except as noted above and except as indicated in footnote to tables of daily discharge. Records prior to August 21, fair; thereafter, good.

OOOPEBATION. - Gage-height record and numerous discharge measurements funyshed

LOCATION. In sec. 3, T, 11 N., R. 3 W., 150 feet below diversion dam of Crane Creek 

Irrigation District, which is about 4$ miles above mouth of Crane Creel?, and 14 

miles northeast of Weiser, Washington County.

RECOBDS AVAILABLE. June 23 to September 30, 1920.

GAGE. Friez water-stage recorder on right side of wooden flume^ inspected fey John 

Eogge.

DISCHARGE MEASUREMENTS. Made from plank across flume.

CHANNEL AND CONTROL. Section of wooden flume forms control. Zero flow at gag© 

height 0.36 foot; determined June 25, 1926.

EXTREMES OF DISCHARGE. Maximum stage recorded during period, from waier-stage 

recorder, 2.83 feet 4 to 8 a. m. July 15 (discharge, 79 second-feet); minimum stage 

1.53 feet at 11 p. m. September 30 (discharge, 25 second-feet). Actual maximum 

and minimum stages may have occurred on a day of no record.

ICE. Canal dry except during irrigation season. '

DIVERSIONS. None between gage and point of diversion. Entire flow diverted below 

for irrigation.

REGULATION . Flow controlled by headgates 150 feet above gage.

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

24 and 70 second-feet. Water-stage recorder operated satisfactorily, but observer 

was frequently unable to visit gage at end of week, and several breaks in record 

therefore occurred. Daily discharge ascertained by applying to rating; table 

mean daily gage height obtained by inspection of recorder graph and by interpolating for days of no record as noted in footnote to daily-discharge table. 

Records good, except those for days of interpolation, for which they are fair.

WEISER IRRIGATION DISTRICT CANAL NEAR WEISER, IDAHO.

LOCATION. In sec. 32, T. 11 N., R. 4 W., at Durbin ranch, 1£ miles below head works 

of canal and 7 miles above Weiser, Washington County.

RECORDS AVAILABLE. -April 29 to September 30,1920.

 GAGE. Friez water-stage recorder in concrete well and house adjacent to left side 

of concrete rating flume; inspected by L, H. Alsop, ditch walker. Zero of gage 

is at bottom of rating flume. ;

DISCHARGE MEASUREMENTS. Made from footwalk across concrete rating flume.

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

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

not subject to appreciable growth of moss or weeds.

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

4.13 feet at 2 p. m. May 23 (discharge, 206 second-feet); minimum stage, 0.84. 

foot at 6 a. m. August 15 (discharge, 21 second-feet).

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

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

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

is located about 1J miles above gage. Water from waste gate returns to Weiaer 

River through a slough which formerly was main channel of river.

ACCURACY. Stage-discharge relation not permanent, owing to cleaning of canal, and

> lodging of brush upon the control. Two rating curves used,which are well d^fiaesa 

between 20 and 200 second-feet; one is applicable April 29 to July 28, August 

9-14, and August 31 to September 30, and the other July 29 to August 4 and
280 SURFACE WATER SUPPLYj 1919--1920, PART XH B.

August 15-30. Operation of water-stage recorder satisfactory. Daily discharge 

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

inspection of recorder graph, except for period August 5-8, for which the shiftingcontrol method was used, and except as indicated in footnote to table of daily 

discharge. Records good.

COOPERATION. Gage-height record and several discharge measurements furnished 

by Stuart M. French, engineer for Weiser Irrigation District.

Weiser Irrigation District canal diverts from right bank of Weiser River in sec. 3, 

T. 10 N., R. 4 W. Water is used for irrigation of about 9,600 acres of land in Weiser 

Valley.

LOCATION. In sec. 6, T. 21 N., R. 22 E., at rear of "Rose ranch buildings, 300 feet 

below the island, just above Lemhi River, and a quarter of a mile below highway 

bridge at Salmon, Lemhi Oounty. '

DRAINAGE AREA. 3,600 square miles (Forest Service records).

RECORDS AVAILABLE. April 25,1912, to September 30,1916; July 6,1919, to September 30, 1920.

GAGE. Inclined staff on left bank; installed October 20,1913; read by S. C. Scribner, 

and E. A. Renner. Prior to October 20,1913, gage was an inclined staff 30 feet 

upstream. Both gages referred to same datum but present gage reads about 0.08 

foot lower.

DISCHARGE MEASUREMENTS. Made from cable 700 feet below gage.

CHANNEL AND CONTROL. One channel at all stages. Bed composed of rock overlain 

with sand and gravel. Control shifts slightly.

EXTREMES OP DISCHARGE. Maximum stage recorded during period July 6, 1919, to 

September 30, 1920, 6.1 feet June 16, 1920 (discharge, 6,810 second-feet); minimum discharge, 710 second-feet August 30 to September 3 and December 8 and 9, 

1919; lower flow may have occurred during periods of no record.

1912-1916; 1919-20: Maximum^ discharge recorded, 12,900 second-feet June 10, 

1912; minimum discharge recorded^ 710 second-feet August 30 to September 3 

and December 8 and 9, 1919; lower flow may have occurred during periods of no 

record.

ICE. Stage-discharge relation usually affected by ice. j

DIVERSIONS. A small ditch diverts from left bank between bridge and gage, but its 

maximum capacity is less than 1 per cent of low-water flow.

REGULATION. None.

ACCURACY. Stage-discharge relation changed during winter of 1919-20; affected by 

ice December 15,1919, to February 8,1920. Two rating curves used; one, applicable July 6,1919, to December 14,1920, fairly well defined above 800 second-feet, 

the other, applicable February 9 to September 30,1920, fairly well defined between 

900 and 7,000 second-feet. Gage read to half-tenths once daily except as indicated 

in footnote to table of daily discharge. Daily discharge ascertained by applying 

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

discharge and except for period during which stage-discharge relation was affected 

by ice for which it was ascertained by means of occasional gage readings, one discharge measurement, observer's notes, and weather records. Records fair.

LOCATION. -In sec. 22, T. 28 N., B. 1 E., at highway bridge at Whitebird, Idaho 

County, just above Whitebird Creek, and 800 feet above Canfield ferry. Below 

all important tributaries.

DRAINAGE AREA. 13,600 square miles (measured on General Land Office map, 

edition of 1909).

BECORDS AVAILABLE. August 18, 1910, to September 30, 1917; October 1, 1919, to 

September 30, 1920.

GAGE. Since September 14, 1920, chain gage on handrail of highway bridge at new 

datum; read by B. E. and L. E. Shuck. Gage used prior to October 4, 1915, 

consisted of low-water section on right bank at ferry landing and high water 

section on left bank 75 feet below cable; October 4, 1915, to September 13, 1920, 

inclined staff in two sections on left bank beneath ferry cable, about 800 feet 

below present site. Temporary gage used December 31, 1916, January 1, 2, 

and 15-20, 1917, when stage was below inclined sections. Gages at same datum 

prior to September 13, 1920.

DISCHARGE MEASUREMENTS. Made from gaging car suspended from ferry cable.

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

below gage; one channel at all stages. Banks not subject to overflow. Control 

composed of section of river channel and large boulder riffle three-eighths of a 

mile below; permanent.

EXTREMES aw DISCHARGE. Maximum stage recorded during year, 15.09 feet June 17 

(discharge, 56,700 second-feet); minimum stage occurred in December when stagedischarge relation was affected by ice (discharge probably below 2,600 secondfeet).

1910-1917; 1919-20: Maximum stage recorded, 20.05 feet at 6 p. m. June 19, 

1916 (discharge, 85,100 second-feet); minimum stage, November 15, 1916, when 

water fell below gage (estimated discharge, 2,500 second-feet).

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

DIVEKSIONS. None of consequence above station. , ,

REGULATION. None.

ACCUKACY. Stage-discharge relation permanent except as affected by ice November 

30 to December 19, January 4-12, and 22-23. Eating curve well denned. Gage 

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

daily gage height to rating table except for periods during which stage-discharge 

relation was affected by ice for which it was ascertained by means of gage heights 

and weather records, and except for period October 1-4 during which no gageheight record was obtained for which it was ascertained by comparison with flow 

of Clearwater River at Kamiah. Open-water records good; winter records poor.
