SURFACE WATER SUPPLY OF SNAKE RIVER BASIN, 1949

SCOPE OF WORK

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

stage and flow made on streams, lakes, and reservoirs in the United States during the 

water year ending September 30, 1949. The work was begun in 1888 in connection with 

special studies relating to irrigation. Measurements of the flow of streams and of the 

stage and contents of lakes and reservoirs have been made at about 11,680 gaging stations 

in the 48 States and also at many in the Territories of Alaska and Hawaii. On September 

30, 1949, 6,240 gaging stations, including those in Hawaii and Alaska were being maintained by the Geological Survey and cooperating organizations. Miscellaneous discharge 

measurements were made during the Water year at many other points.

In the execution of the work many State and private organizations have cooperated, 

either by furnishing data or by assisting in collecting data. Cooperation of the first 

kind is acknowedged in connection with the description of each station affected; cooperation of the second kind is acknowledged; under the heading "Cooperation," in the introductory matter that precedes the gaging-statlon records in each volume. In the present 

volume, the section on cooperation of the second kind appears on page 12.

DEFINITION OF TERMS

The units in which stream-flow data are presented in this report and other terms used 

herein are defined as follows:

"Second-f«et" is an abbreviation for "cubic feet per second." A second-foot is the 

rate of discharge of a stream whose channel is 1 square foot in cross-sectional area and 

whose average velocity is 1 foot per second.

"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 ths runoff is distributed uniformly both as regards time and area.

"Runoff in inches" is the depth to which an area would be covered if all the water 

draining from it in a given period were uniformly distributed on its surface. It is used 

for comparing runoff with rainfall, which is usually expressed in inches.

An "acre-foot" is the quantity of water required to cover an acre to the depth of 

1 foot and is equivalent to 43,560 cubic feet. The term is commonly used in connection 

with storage for irrigation.

"Second-foot-day" is the volume of water represented by a flow of 1 second-foot for 24 

hours. It is equivalent to 86,400 cubic feet, 1.983471 acre-feet, or 646,317 gallons and 

represents a runoff of 0.0372 inch from 1 square mile.

"Stage-discharge relation" is an abbreviation for the term "relation between gage height 

and discharge."

"Control" is a term used to designate a feature downstream from the gage that determines the stage-discharge relation at the gage. This feature may be a natural section, 

a reach of the channel, or an artificial structure.

2 SURFACE WATER SUPPLY, 1949, PART 13

"Contents" is a terra applied to the volume of water In a reservoir. Unless otherwise 

Indicated, It Is computed on the basis of a level pool and does not include bank storage.

EXPLANATION OP DATA

The base data collected at gaging stations consist of records of stage, measurements 

of discharge, and general information used to supplement the records of stage and discharge 

measurements in determining the daily flow. The records of stage are obtained either from 

direct readings on a nonrecording gage or from a water-stage recorder that gives a continuous record of the fluctuations. Measurements of discharge are made with a current 

meter by the general methods outlined in standard textbooks on the measurement of river 

discharge. Typical structures in use at gaging stations are shown in figure 1.

Rating tables giving the discharge for any stage are prepared from the discharge measurements. The application of the daily mean gage height to those rating tables gives the 

daily mean discharge, from which the monthly and, the yearly mean discharge are computed. 

If the stage-discharge relation is subject to change because of frequent or continual 

change In the physical features that form the control, the daily mean discharge is determined by the "shifting-control method," in which correction factors based on individual discharge measurements and notes by engineers and observers are used in applying the 

gage heights to the rating tables. At .times the stage-discharge relation for a station 

may be temporarily changed by the presence of aquatic growth or debris on the control. 

For such times the daily mean discharge is computed by what is essentially the "shiftingcontrol" method, described above.

At some gaging stations the stage-discharge relation is affected by backwater from 

reservoirs, tributary streams, or other sources, which necessitates the use of the "slope 

method," in which the slope or fall in a reach of the stream is a factor in the determination of discharge. Information requisite for determining the slope or fall is obtained 

by means of an auxiliary gage set at some distance from the base gage. At some stations 

the stage-discharge relation is affected by changing stage, and for them the rate of 

change of stage is used as a factor in the determination of discharge.

At most gaging stations in the northern part of the United States and at some in the 

mountainous regions of other- parts the stage-discharge relation is affected by ice during 

the winter, which makes it Impossible to compute the discharge in the usual manner. Discharge for periods of ice effect is computed on the basis of the gage-height record and 

occasional winter discharge measurements, consideration being given to the available information on temperature and precipitation, notes by gage observers and engineers, and 

comparable records of discharge for stations in the same or nearby basins. For those 

stations at which the stage-discharge relation ^s affected by ice, the days included in 

the periods of ice effect either are indicated in the table by symbols referring to a 

footnote that states this fact or are given in a general note following the table. The 

days on which discharge measurements were made during or between periods of ice effect, 

shortly before the first period, or shortly after the last period are similarly indicated 

by a footnote.

For most of the gaging stations on streams in the area covered by this report the data 

presented comprise a description of the station, a table showing the daily discharge of

the stream, and a table of monthly and yearly discharge and runoff. Skeleton rating 

tables are published for all stations except those at which the daily discharge for the 

greater part of the year was determined by the shifting-control method, the slope method, 

or other special methods.

The description of the station gives the type of gage, location, drainage area, records 

available, average discharge, extremes of discharge, general remarks, and notations of revisions of previously published record. The location of the gaging station and the drainage area are obtained from the most accurate maps available. Under "Average discharge" is 

given the average discharge for the number of years indicated. It is net given for stations having less than 10 complete years of record or for stations where changes in water 

development during the period of record cause the figure to have little significance. 

Under "Extremes" are given the maximum discharge and gage height; the minimum discharge if 

there is little or no regulation; the minimum daily discharge if there is extensive regulation (also the miniitfum discharge if useful); and the minimum gage height (unless it is 

of no importance). Unless otherwise qualified, the maximum discharge corresponds to the 

crest stage, obtained by use of a water-stage recorder or a nonrecording gage read at the 

time of the crest. Information pertaining to the accuracy of the records and conditions 

which affect the natural flow at the gaging station is given under "Remarks."

For some stations previously published records have been found to be in error on the 

basis of data or information obtained subsequently. Revisions of such records are usually 

published along with the current records in one of the annual reports. In order to make 

it easier to find such revised records, a paragraph headed "Revisions (water years)" has 

been added to the station description of all stations for which revised records have been 

published. Listed therein are all the reports in which revisions appear, each followed by 

the water years for which figures are revised in that report. In listing the report 

number, W. means Water-Supply Paper. In listing the years, water years are indicated by 

only 1 year, for instance, 1933 stands for the water year October 1, 1932, to September 30, 

1933. If there were no daily, monthly, or annual figures of discharge involved in the 

revision, that fact is brought out by notations after the year dates as follows: (M) means 

that only the Instantaneous maximum discharge was revised; (m) that only the instantaneous 

minimum was revised; and (P) that only peak discharges were revised. If the drainage area 

has been revised, the report in which the revised figure was first published is given. It 

should be noted that for all stations for which second-feet per square mile and runoff in 

inches are published, a revision of the drainage area necessitates corresponding revision 

of all figures based on the drainage area. Revised figures of second-feet per square mile 

and runoff in inches resulting from a revision of the drainage area only are usually not 

published in the annual series of reports.

For stations equipped with water-stage recorders, except those on streams subject to 

sudden or rapid fluctuation, the table gives the discharge corresponding to the daily mean 

gage height. For stations subject to such fluctuation the daily mean gage height may not 

indicate the true daily mean discharge, which must be obtained by averaging the discharge 

for parts of the day or by using the discharge integrator, an instrument for obtaining the 

daily mean discharge from a continuous gage-height graph and containing as an essential 

element a curve representing the stage-discharge relation at the station. For stations 

equipped with nonrecording gages, the table of daily discharge gives the discharge
ACCURACY OP FIELD DATA AND COMPUTED RESULTS 5

corresponding to either once-daily readings of the gage, the mean of twice-daily readings, 

or the mean gage height determined from gage-height graphs based on gage readings. For 

periods of rapidly changing stage, the daily mean discharge is determined from gage-height 

graphs based on gage readings, the frequency of which is stated in the station description.

In the table of monthly discharge the column headed "Second-foot-days" gives the sum 

for each month of the figures given in the table of daily discharge. The column headed 

"Maximum" gives the maximum daily discharge, not the momentary discharge when the water 

surface was at crest stage. Likewise, in the column headed "Minimum" the quantity given 

is the minimum daily discharge. The column headed "Mean" gives the average flow in cubic 

feet per second during the month.

Peak discharges with the times of their occurrence are listed below the table of monthly 

discharge for most stations. All independent peaks above the selected base are given. The 

base discharge, which is given in parentheses, is selected so that an average of about 

three peaks a year will be presented. Peak discharges are not published for canals, 

ditches, drains, or for any stream for which the peaks are subject to substantial control 

by man.

For most gaging stations on lakes and reservoirs the data presented comprise a description of the station and a monthly summary table of stage and contents. For some reservoirs a table showing daily contents or stage is given. A skeleton table of capacity at 

given stages is usually given in the first report in which data for a station are published 

but is omitted from succeeding reports.

The accuracy of stream-flow data depends primarily on (1) the permanency of the stagedischarge relation or, if the control is unstable, the frequency of discharge measurements 

and (2) the accuracy of observations of stage, measurements of flow, and interpretation of 

records.

The station description gives a statement in regard to the general accuracy of the records. "Excellent" indicates that, in general, the error in the daily records is believed 

to be less than 5 percent; "good," less than 10 percent; "fair," less than 15 percent; and 

"poor," probably more than 15 percent. The records of monthly and yearly mean discharge 

and runoff are, in general,- more accurate than the daily records.

Yield at some stations as indicated by monthly means may vary widely from natural yield, 

owing to diversion, consumption, regulation by storage, increase or decrease in evaporation 

due to artificial causes, or other factors. For such stations figures of "second-feet per 

square mile" and "runoff in inches" are not published unless storage or diversion records 

are included indicating the extent of the regulation or diversion or unless satisfactory 

adjustments can be made for changes in contents or reservoirs or for other changes incident 

to use and control. Evaporation from a reservoir is not included in the adjustments for 

changes in reaervoir contents, unless its inclusion is indicated. Even at those stations 

where adjustments are made, in soaie instances large errors in computed yields may occur 

when relatively large negative adjustments are applied or when evaporation is large in 

comparison with the observed discharge. Figures of second-feet per square mile and runoff 

in inches are also omitted if the drainage area includes large noncontributing areas or if 

the average annual rainfall over the drainage area is less than 20 inches.
6 SURFACE WATffl SUPPLY, 1149, PART 13

Many gaging stations on streams In the Irrigated areas of the United States are situated 

above most of the diversions from those streams, and therefore the discharge recorded does 

not show the water supply available for further development, as prior appropriations below 

the station must first be satisfied.

The table of monthly discharge presents In summary the distribution of the flow past the 

station. The table of dally discharge affords opportunity for more detailed studies of the 

variation in flow. As further observations in each succeeding year may be expected to 

throw new light on data previously published, it should be borne in mind that such data are 

subject to revision in succeeding water-supply papers.

PUBLICATIONS

The results of stream-flow measurements are now published annually in 14 parts, each 

part covering an area whose boundaries coincide with natural drainage features as indicated 

below:

The records at most of the stations discussed In these reportB extend over s series of 

years. Miscellaneous measurements at many points other than regular gaging stations have 

been made each year and are published under "Miscellaneous discharge measurements" at the 

end of each report, the streams and points of measurement listed appearing In the same 

relative order as the streams and gaging stations in the body of the report. An index of 

the records obtained prior to 1904 has been published In Water-Supply Paper 119.

Each of the reports on surface water supply for the year 1939, Issued as Water-Supply 

Papers 871 to 884 (see table on p. 8), contains, for the area covered by that report, a 

suttcnary of yearly discharge at gaging stations at which 10 or more complete years of record 

have been collected. These summaries are available also as separate reprints.

Reports have been publlsned that are compilations of records for various areas, usually 

a single State or drainage basin. These reports contain records previously published 

(some of which have been revised), as well as some records not contained in the annual 

series of water-supply papers. The following table gives the numbers and titles of these 

reports, arranged alphabetically, some by States and some by drainage basins.

feet); no usable contents on several days during period August to October 1919 (elevation, 6,730.00 feet).

Remarks . Reservoir was formed by log crib dam in 1906 with a usable capacity of 300,000 

acre-feet. The dam washed out in July 1910 and was replaced oy an earth dam, forming 

a reservoir with a usable oapaoity of 380,000 acre-feet. The earth dam was raised in 

1916 increasing the usable capacity to 790,000 acre-feet. In 1917, by dredging the 

outlet, the capacity was further increased to 847,000 acre-feet between elevatlona 

6,730 feet (top of baffles to aluices) and 6,769 feet (top of spillway gates). Water 

ie used for irrigation in Snake River Valley, Idaho. Gage read once daily at 8 a.m.

SNAKE RIVER MAIN STEM 19

Diversions from Snake River between Heise and Shelley gaging stations, Idaho

Between Heise and Shelley gaging stations, 47 canals divert water from Snake River for 

irrigation; of these 36 divert above mouth of Henrys Pork. Records available during each

f Fragmentary gage-height record; discharge computed from'partly estimated gage heights. 

Note.--No gage-height record Jan. 10-24, Jan. 29 to Feb. 65 discharge computed on basis of records 

for stations near Buhl and at King Hill.
32 SNAKE RIVER MAIN STEM

Snake River at King Hill, Idaho

Location. --Mater-stage recorder, lat. 43°00', long. 115°11', in SW^- sec. 7, T. 5 S., R. 

mrr, 300 feet east of railroad station at King Hill and 20 miles downstream from 

Big Wood River. Datum of gage is 2,492.3 feet above mean sea level, by stadia levels.

Records available.--May 1909 to September 1949.

Extremes.--Maximum discharge during year, 18,100 second-feet Feb. 25 (gage height, 9.54 

I'eet); minimum, probably less than 2,500 second-feet at times when stage was below 

intake on several days during period Sept. 21-30; minimum daily, 5,790 second-feet 

July 10.

1909-49: Maximum discharge observed, 47,200 second-feet June 22, 1918 (gage height, 

16.3 feet), from rating curve extended above 30,000 second-feet; minimum, probably less 

than 2,500 second-feet at times when stage was below intake on several days during 

period Sept. 21-30, 1949; minimum daily, 4,760 second-feet July 7-9, Aug. 15, 16, 1910.

Remarks.--Records good. Flow regulated by power plants at Lower Salmon Falls and near 

Bliss and many reservoirs above station. Practically entire flow at Milner diverted 

during irrigation season; flow at King Hill is then derived largely from springs and 

seepage entering below Milner.

SNAKE RIVER MAIN STEM 35

Snake River at Oxbow, Oreg.

Location. Water-stage recorder, lat. 44°57', long. 116°51', in NW£ sec. 16, T. 7 S., R. 

4H K., at Oxbow, five-eighths of a mile upstream from intake of diversion tunnel for 

Oxbow power plant and 2^ miles upstream from Indian Creek. Datum of gage is 1,696.71 

feet above mean sea level, datum of 1929, supplementary adjustment of 1947.

Records available. May 1923 to September 1949.

Extremes. Maximum discharge during year, 37,400 second-feet Mar. 19; maximum gage height, 

about 29 feet (ice jam), from floodmark, sometime during period Jan. 17-27; minimum, 

8,320 second-feet July 11 (gage height, 7.55 feet).

1923-49: Maximum discharge, 74,600 second-feet Apr. 21, 1943; maximum gage height, 

that of January 1949; minimum, 4,890 second-feet Aug. 6, 1924 (gage height, 6.30 feet).

Remarks. Records excellent except those for period of ice effect, which are good. Flow 

regulated by many reservoirs above station. Diurnal fluctuation caused by Swan Falls 

power plant. Some diversions below Weiser for irrigation.

92 MOD LAKE BASIN

Mud Lake near Terreton, Idaho

Location. Water-stage recorder, lat. 43°53', long. 112°24i, In SW£ sec. 1, T. 6 N., R.

 34 i!., 2 miles north of First Owsley pump house, 2f miles northeast of Terreton, and 

14 miles southwest of Hamer; supplemental staff gage at pump house. Datum of each 

gage is 4,775.33 feet above mean sea level.

Records available.--April 1921 to September 1949.

Extremes. Maximum contents during year, 43,500 acre-feet Apr. 89 (gage height, 8.55

reet); minimum daily, 4,940 acre-feet Aug. 22; minimum gage height, 0.51 foot Sept. 16 

(affected by wind).

1921-49: Maximum contents observed, 61,660 acre-feet May 5, 1923 (gage height, 9.20 

feet); practically no contents Oct. 1 to Nov. 15, 1937 (at 4 p.m. Nov. 15 water was released from Camas Creek into lake).

Remarks. Mud Lake is a perched body of water confined by earth dikes and fed by ground-

 waTer and surface tributaries augmented by well flows. For complete description of 

Mud Lake region see Water-Supply Paper 818. Water for irrigation is diverted from lake 

by pumping. During low-lake stages inflow from Camas Creek may be bypassed through 

Camas Creek diversion canal directly to lake outlet channel' leading to First Owsley 

pumping plant. Bypass was not used during 1949. Other irrigation diversions are made 

by various means from adjacent lakes and wells and Camas Creek above lake. Area of 

Mud Lake is varied from time to time by changes in dikes. Figures given herein represent contents above gage height -4.0 feet. Capacity table prepared from surveys made 

by Geological Survey and adjusted for changes in dikes. High winds occasionally disturb the recording of lake stages.

Cooperation.--Water-stage recorder inspected by Water District No. 66 and supplemental

* Winter discharge measurement made on this day.

Note. Stage-discharge relation affected by Ice Nov. 27 to Dec. 2, Dec. 5 to about Mar. 14 (no 

gage-height record Dec. 28 to Feb. 21, Feb. 25 to Mar. 14j discharge computed on basis of weather 

records and flow during adjacent periods).
110 BIG LOST RIVER BASIN

Warm Spring Creek (east channel) near Mackay, Idaho

Location.--Water-stage recorder, lat. 430 58', long. 113°45', In NEj- sec. 5, T. 7 N., R, 

23 E., 700 feet upstream from confluence with west channel and 7? miles northwest of 

Mackay.

Records available. May 1919 to September 1949. 

Average discharge.--30 years, 28.7 second-feet.

Extremes. Maximum discharge during year, 109 second-fee-t May 20 (gage height, 2.94 feet); 

minimum, 20 second-feet Apr. 20-28, May 1-8.

1919-49: Maximum discharge observed, 225 second-feet June 15, 1922 (gage height, 

3.24 feet, site and datum then in use); minimum, 9 second-feet May 8, 9, 13, 14, 1919, 

May 18-21, 1920.

Remarks.--Records good except those for periods of no gage-height record and those for Sept. 

14-30, which are fair. Practically all natural flow above station diverted during irrigation season. Discharge during summer represents return water from irrigation. The 

sum of the combined discharge of east and west channels of Warm Spring Creek and the 

combined discharge of east and west channels of Big Lost River, near Mackay, represents 

practically the entire surface flow of Big Lost River which enters Mackay Reservoir.

Cooperation.--Water-stage recorder graph furnished by Water District No. 27.

flow at times during most years.

Remarks.--Records good except those for Apr. 15 to May 10, which are fair, and those for 

periods of ice effect or no gage-height record, which are poor. Canal diverts from 

Canyon Creek in sec. 36, T. 2 S., R. 6 E., and delivers water to Mountain Home cooperative canal, which heads in Mountain Home feeder canal half a mile below station, for 

irrigation of about 5,000 acres in Mountain Home Irrigation District. During nonirrigation season and at times when there is a surplus of water for irrigation, canal feeds 

directly into Mountain Home Reservoir. No diversion from canal above station; two 

small diversions between station and headgates of Mountain Home cooperative canal. 

Plow regulated by headgates in Canyon Creek and by Long Tom and Little Camas Reservoirs.

Discharge, In second-feet, water year October 1948 to September 1949

OWYHEE RIVER BASIN

Owyhee Reservoir at Owyhee Dam, near Nyssa, Oreg.

Location. Staff gage, lat. 43°38', long. 117° 15', in sec. 20, T. 22 S., R. 45 E at

 Owyhee Dam, 21 miles southwest of Nyssa. Datura of gage is at mean sea level (levels 

by Bureau of Reclamation).

Drainage area.--11,160 square miles.

Records available. October 1932 to September 1949.

Extremes. Maximum contents observed during year, 1,010,100 acre-feet June 7 (elevation.

 2,£>o'0.88 feet); minimum observed, 630,600 acre-feet Oct. 1 (elevation, 2,622.30 feet).

1932-49: Maximum contents observed, 1,125,000 acre-feet June 11, 1936 (elevation, 

2,670.27 feet); minimum observed since full capacity was attained on May 7, 1936, 

630,500 acre-feet Sept. 30, 1948 (elevation, 2,622.29 feet).

'emarks.--Reservoir is formed by concrete arch-gravity dam, completed in September 1932;

 storage began Oct. 16, 1932. Capacity, 1,121,800 acre-feet between elevations 2,367.5 

feet (bottom of sluice gates) and 2,670 feet (top of spillway gate), 715,000 acre-feet 

between elevations 2,590.2 feet (diversions tunnel) and 2,670 feet. Dead storage below 

elevation 2,367.5 feet negligible. Figures given herein are of contents above elevation 2,367.5 feet. The reservoir will generally not be drawn below elevation 2,590.2 

feet. Water is released through diversion tunnel to South Canal for irrigation of 

lands west of Snake River in the vicinity of Homedale, Idaho, and to North Canal for 

irrigation of lands north and west of Owyhee River, and through sluice gates to river 

for Owyhee Canal, which diverts about 18 miles downstream. Gage read once daily.

herein represent contents above elevation 3,327 feet. Storage began in 1919. In 1926 

a half interest in reservoir was purchased by the Federal Government for Vale project 

of Bureau of Reclamation. Water used to irrigate lands on both sides of river between 

Namorf and Ontario. Once-daily gage readings and data for computing capacity table 

furnished by Bureau of Reclamation.

Agency Valley Reservoir.--Pressure gage with mercury column, lat. 43°55', long. 118°09', 

in sw£ sec. it>, T. 19 S., R. 37 E., at dam on North Fork Malheur River, a quarter of 

a mile northwest of Beulah. Gage readings are elevations above mean sea level by 

original surveys of Bureau of Reclamation, or 7.72 feet less than elevations above 

mean sea level, datum of 1929. Drainage area, 420 square miles. Records available, 

December 1935 to September 1949. Maximum contents observed during year, 58,550 acrefeet Apr. 22 (elevation, 3,339.27 feet); minimum observed, 10,160 acre-feet Sept. 30 

(elevation, 3,301.80 feet). Maximum contents observed during period 1935-49, 62,770 

acre-feet May 3, 1941 (elevation, 3,341.50 feet); minimum observed since full capacity 

was attained Apr. 9, 1938, that of Sept. 30, 1949.

Reservoir is formed by earth-fill, rock-faced dam; storage began in December 1935. 

Capacity, 59,920 acre-feet between elevations 3,263.21 feet (bottom of outlet tunnel) 

and 3,340 feet (top of 17-foot spillway gates); with gates lowered the capacity is 

32,220 acre-feet. No dead storage. Water is used for irrigation of lands below 

Juntura, on Vale project of Bureau of Reclamation. Capacity table and daily gage 

readings furnished by Bureau of Reclamation.

Other reservoirs.--There are several other reservoirs in the Malheur River Basin, all 

with less than 3,500 acre-feet capacity except Willow Creek No. 3 Reservoir near 

Malheur, which has a capacity of 49,000 acre-feet.

Records available. --October 1945 to September 1949 in reports of Geological Survey; March 

iy3Y to September 1941 in reports of State engineer; October 1941 to September 1945 in 

files of State engineer. August 1903 to March 1907, February 1910 to May 1917, March 

1922 to June 1923 at site 9 miles upstream, in reports of Geological Survey; February 

to June 1919 in reports of State engineer. April 1904 to December 1905 at site at Vale, 

6 miles downstream, in reports of Geological Survey; May to September 1938 in files of 

State engineer. April 1933 to May 1936 (fragmentary) at site 3 miles upstream, in files 

of State engineer. Records at various sites not equivalent because of diversions and 

increasing return flow from Vale-Oregon Canal since 1931.

Average discharge. --13 years (1933-34, 1937-49), 39.6 second-feet.

Extremes . Maximum discharge during year, 310 second-feet Mar. 23; maximum gage height, 

 3.4 'feet Feb. 16 (ice jam); minimum daily discharge, 3 second-feet Jan. 11, 12, 24-26. 

1903-7, 1910-17, 1919, 1922-23, 1933-49: Maximum discharge, 6,240 second-feet

Mar. 1, 1910 (gage height, 8.6 feet, site and datum then in use), from rating curve

extended above 1,200 second-feet; no flow at times.

Remarks. Records fair except those for periods of ice effect or no gage-height record, 

wnTch are poor. Occasional fluctuations caused by releases from Vale-Oregon Canal of 

Vale-Oregon Irrigation District, which diverts water from Malheur River for irrigation 

of lands west of Vale; considerable return flow at times enters Bully Creek above 

station. Small diversions above station for irrigation.

Cooperation. Water-stage recorder inspected by employees of Vale-Oregon Irrigation District.

PAYETTE RIVER BASIN 181

North Fork Payette River near Banks, Idaho

Location.--Water-stage recorder, lat. 44°07', long. 116°06', in SEs: sec. 16, T. 9 N., R.

 3'E., 40 feet downstream from steel highway bridge, 2j miles north of Banks, and 3 miles 

upstream from confluence with South Fork. Datum of gage is 3,081.13 feet above mean 

sea level, preliminary unadjusted elevation.

Drainage area.--933 square miles.

Kecords available. April 1947 to September 1949.

Extremes.--Maximum discharge during year, 3,540 second-feet May 21; maximum gage height,

 lU.b'o1 feet Jan. 28 (ice jam); minimum recorded, 50 second-feet Dec. 17 (gage height, 

3.15 feet ), but may have been less during period of ice effect.

1947-49: Maximum discharge, 8,830 second-feet May 11, 1947, computed on basis of 

records for station near Smiths Ferry; minimum recorded, 36 second-feet Dec. 31, 1947 

(gage height, 3.01 feet).

Remarks.--Records excellent except those below about 500 second-feet, which are good, and 

those for periods of ice effect or no gage-height record, which are fair. Flow regulated by Payette Lake (see p. 177), Lake Fork Reservoir (see p. 184), Cascade Reservoir (see p. 179) and occasionally by mill dam at Cascade. Many diversions from 

tributaries above station for irrigation.

below Lake Irrigation District Canal, Johnson Creek at Yellow Pine, and other nearby streams.
184 PAYETTE RIVER BASIN

Lake Pork Reservoir near McCall, Idaho

Location. Staff gage and graduations on concrete gate-control structure of dam on Lake

 itork Payette River, lat. 44°54', long. 116°03', in Nwpwir sec. 13; T. 18. N., R. 3 E., 

3 miles east of McCall. Datum of gage is at mean sea level (levels by Lake Irrigation 

District).

Records available.--April 1926 to September 1949.

Extremes.--Maximum contents observed during year, 19,120 acre-feet June 17 (elevation,

 b,liy.37 feet); practically no storage at times during fall and winter.

1926-49: Maximum contents observed, 19,740 acre-feet June 19, 1941 (elevation, 

5,118.75 feet); practically no storage above elevation 5,101.0 feet for long periods 

during fall and winter of most years.

Remarks.--Reservoir is formed by earth- and rock-fill dam coir^leted in 1926. Capacity,

 IE7940 acre-feet between elevations 5,101.0 feet (lower limit of capacity table, 4.0 

feet above gate sill of outlet) and 5,117.0 feet (top of flashboards, 5.0 feet above 

spillway crest). Dead storage unknown. Water is used for irrigation of about 6,800 

acres of land in vicinity of Norwood. Figures given herein represent contents above 

5,101.0 feet. There is some usable storage below elevation 5,101.0 feet, but natural 

flow passing through reservoir when outlet gates are operating prevents withdrawal of 

storage to elevation of sill of gates. Gage reading of 5,099.64 feet observed Apr. 2. 

Gage read once daily. Time of reading variable. Storage figures from gage heights as 

observed.

Cooperation.--Elevation record and capacity table furnished by Lake Irrigation District.

222 SALMON RIVER BASIN

Salmon River at Whitebird, Idaho

Location.--Water-stage recorder, lat. 45°45', long. 116°20', In sec. 22, T. 38 N., R. 1 

t., Just upstream from Whltebird Creek, half a mile downstream from Canfleld-Joseph 

highway bridge, and 1 mile southwest of Whitebird. Datum of gage is 1,412.65 feet above 

mean sea level, datum of 1929, supplementary adjustment of 1947.

Drainage area. 13,550 square miles, Including that of Whltebird Creek.

Records available. August 1910 to September 1917, October 1919 to September 1949.

Average discharge. 37 years, 10,510 second-feet.

Extremes. Maximum discharge during year, 76,500 second-feet May 16 (gage height, 29.04 

reet); minimum, 2,430 second-feet Dec. 19 (gage height, 11.53 feet), but may have been 

less during period of ice effect.

1910-17. 1919-49: Maximum discharge, 103,000 second-feet June 3, 1948 (gage height, 

32.95 feet); minimum, 1,580 second-feet Dec. 11, 1932 (gage height, 10.23 feet), from 

rating curve extended below 2,200 second-feet.

Maximum stage known, about 37.5 feet, present datum, June 1894 (discharge, 120,000 

second-feet).

Remarks. Records excellent except those for periods of ice-effect or no gage-height recora, which are fair. Amount of water diverted above station for irrigation is a negligible percentage of total flow.

Revisions (water years). W 753: 1932. W 1043: Drainage area.

Discharge, in second-feet, water year October 1948 to September 1949
