FLOODS OF DECEMBER 1955-JANUARY 1956 IN THE FAR WESTERN STATES

PART 2. STREAMFLOW DATA

By Walter Hofraan and S. E. Rantz

INTRODUCTION

Water-Supply Paper 1650-B presents basic hydrologic information on the floods of 

December 1955-January 1956 and complements the descriptive material in 1650-A. 

Basic records of stage and discharge in the area covered by this report are collected by the U.S. Geological Survey as part of a continuous program in cooperation 

with the States of California, Idaho, Oregon, Nevada and Washington; county and 

city agencies within these states; and agencies of the Federal Government. The 

records of stage and discharge were collected and computed under the direction of 

the following district engineers; California, R. C. Briggs, succeeded by R. S. 

Lord; Idaho, T. R. Newell; Oregon, K. N. Phillips; Nevada, M. T. Wilson; Washington, 

F. M. Veatch.

EXPLANATION OF DATA

The report data consist of records of stage and discharge for gaging stations, 

and peak-stage and peak-discharge information for numerous miscellaneous sites and 

partial-record stations in or on the fringe of the area of intensive flooding. The 

records are presented in more detail than those in the regular annual reports and 

are more useful for the many hydraulic and hydrologic studies relative to flood 

phenomena.

The basic data collected at stream-gaging stations consist of records of stage, 

measurements of discharge, and general information useful in determining the daily 

flow. The records of stage are obtained either from the continuous trace of a 

water-stage recorder or from periodic direct readings on a nonrecording gage. Discharge measurements are generally made by use of a current meter; however, indirect 

methods are used at times.

In general, the information presented for each gaging station is: a description 

of the station, a tabulation of daily mean discharges for December 1955 and January 

1956, a tabulation of stages and discharges at selected intervals during each day 

of the flood rise and recession for the two or three highest floodpeaks during the 

2-month period. For the miscellaneous sites and partial-record stations, only the 

station description is presented.

The station description gives information relative to: the location of the 

gage; size of the drainage area above the gage; nature of the gage-height record
2 FLOODS, DECEMBER 1955-JANUARY 1956, FAR WESTERN STATES

obtained during the period covered by this report; datum of gage; definition of 

the stage-discharge relation; maximum stage and discharge during the December 1955 

and January 1956 flood; previous maximum during the period of record; available 

maximum data for floods outside the period of record; the effect of regulation and 

diversion; and other pertinent general information.

Daily mean discharges during the months of December 1955 and January 1956 

follow the station description for each gaging station. In general, this 2-month 

period shows antecedent conditions, flood flows, and enough of the flood-recession 

records to allow adequate study of the flood hydrology. Also shown in these 

tables are the monthly mean discharge in cubic feet per second and the volume of 

monthly runoff in acre-feet and in inches. The monthly runoff is not given for 

stations where regulation or diversion affect the runoff significantly or where 

the drainage area has not been determined.

The tables of stage and discharge at selected times, where such detailed definition is warranted, follow the daily mean discharge tables. Enough detail is 

presented so that hydrographs of the two or three highest flood peaks may be accurately constructed. Because these flood peaks did not occur on the same days 

throughout the entire area, the periods of detailed record do not necessarily 

coincide for all stations.

Most of the stage data were obtained from records of continuous water-stage 

recorders. For stations with nonrecording gages or where the water-stage recorder was not functioning properly, the indicated stages were obtained from 

graphs constructed from gage readings, floodmarks, and by comparison with nearby 

stations. Details of the methods used at each station .are given in the "Gageheight record" paragraph of the station description.

The sites for which stage and (or) discharge data are presented in this report 

are numbered in downstream order from the headwater of the stream to the mouth; 

sites on tributaries are inserted in the order in which the tributaries enter the 

main stream. This is the same order in which records are presented in the Geological Survey annual series of water-supply papers. However, in the annual series 

publication the sites in this report are distributed among the following five separate parts: Part 10, the Great Basin; Part 11, Pacific slope basins in California; Part 12, Pacific slope basins in Washington and the upper Columbia River 

basin; Part 13, the Snake River basin; Part 14, Pacific slope basins in Oregon and 

the lower Columbia River basin. To maintain a continuous numerical sequence in 

this report, the site numbers have been arranged in ascending part order, beginning with Part 10.

The area covered by this report has been divided into eight subareas or hydrologic regions plus an area of minor flooding.

13. Topaz Reservoir near Topaz, Calif.

Location. Lat 38°41', long 119°31', in sec.28, T.10 N., R.22 E., 6 miles north of 

Topaz.

Gage-height record. Float and staff gages read approximately once daily at unscheduled times. Datum of gage is at mean sea level.

Maxima. December 1955 to January 1956: Contents, 36,420 acre-ft Jan. 31 (elevation, 

4T9"94.13 ft,approximately).

1931 to November 1955: Contents, 60,240 acre-ft June 30, 1941 (elevation, 

5,005.35 ft).

Remarks. Topaz Reservoir, formerly known as Alkali Lake, was formed by the diversion of water from West Walker River through a feeder canal and the construction 

of an outlet tunnel through a low saddle in rim of lake. Storage began Jan. 30, 

1922. Usable capacity, 59,440 acre-ft between elevations 4,972.3 ft (lowest 

practical elevation for diversion through tunnel, bottom of outlet tunnel at elevation 4,970 ft) and 5,005 ft (3 ft below top of levee). Capacity of reservoir 

increased from about 45,000 to 59,440 acre-ft in October 1937 by an earthfill, 

rock-faced levee at south end. Water Is used for irrigation in Walker River 

Irrigation District. Elevations furnished by Walker River Irrigation District.

Gage-height record.--Water-stage recorder graph. Datum of gage is at mean sea level.

Maxima.--December 1955 to January 1956: Elevation, 187.40 ft Jan. 31. 

1906 to December 1955: Elevation, 196.8 ft June 27, 28, 1941. 

Lake elevation of June 27, 28, 1941, was highest known since about 1890.

Remarks. Tulare Lake receives water from Kings, Kaweah, and Tule Rivers during highwater periods and occasionally from Kern River, Deer Creek, and several small 

intermittent streams. Natural boundary of lake has been greatly altered by construction of levees and other reclamation work and storage In 1956 was confined 

to 12 sections or approximately 7,680 acres. Elevation at lowest point of lake 

is now about 180 ft above mean sea level.

portion of Bowman Dam on Canyon Creek, 4 miles east of Graniteville and 8 miles 

south of Sierra City.

Drainage area. 29.4 sq mi.

Gage-height record. Staff gage read irregularly. Datum of gage is 5,000.0 ft above 

mean sea level. Gage readings have been reduced to elevations above mean sea 

level.

Maxima.--December 1955 to January 1956: Contents, 64,200 acre-ft Jan. 30 (elevation, 

5,558.0 ft).

1926 to November 1955: Contents observed, 70,500 acre-ft one or more days in 

1937, 1943, 1950, 1951, 1953 and 1954 (elevation, 5,565.9 ft).

Remarks. Lake is formed by one rockfill and one concrete-arch dam; they were completed and storage began in November 1926. Capacity, 68,200 acre-ft between elevations 5,400 ft (bottom of outlet tunnel) and 5,563 ft (crest of concrete-arch 

dam) above mean sea level. Plashboards are occasionally added, increasing elevation to 5,564.5 ft and capacity to 69,400 acre-ft. Lake receives water from 

Middle Yuba River through Milton-Bowman tunnel and releases it through BowmanSpaulding Canal which conveys it to reservoirs of Pacific Gas & Electric Co. 

Water is eventually used for irrigation by Nevada Irrigation District. Record of 

contents, computed from gage readings made at irregular times, shows total 

contents, all of which are available for release.

Jan. 7, for which graph was reconstructed on basis of frequent Telemark readings. 

Datum of gage is 0.12 ft above mean sea level.

Discharge record. Stage-discharge relation defined by current-meter measurements.

Maxima.--December 1955 to January 1956: Discharge, 95,300 cfs 4:30 p.m. Dec. 23 

[gage height, 28.67 ft).

1949 to November 1955: Discharge, 104,000 cfs 10:00 a.m. to 12 m. Nov. 21, 

1950; gage height, 30.14 ft 12 m. Nov. 21, 1950.

Maximum known prior to Nov. 21, 1950: Discharge, 103,000 cfs Jan. 17, 1909 

(gage height, 29.6 ft), from reports of California Division of Water Resources.

Remarks. Flow regulated by Shasta Lake (see station 253), Folsom Reservoir (see 

station 349), and several other reservoirs and powerplants above station, and by 

bypassing for flood control. When discharge at Verona exceeds about 55,000 cfs, 

flow begins over Premont weir (26 miles upstream) into Yolo bypass (see 

station 365). When stage at Sacramento reaches 27.5 ft, gates are opened in 

Sacramento weir 4 miles upstream (see station 332) to reduce discharge at 

Sacramento.

mean sea level, datum of Bureau of Reclamation. Gage readings have been reduced 

to elevations above Bureau of Reclamation datum.

Maxima. December 1955 to January 1956: Elevation, 4,142.68 ft llp.m. Jan. 22.

1904 to November 1955: Elevation, 4,144.98 ft about Apr. 20, 1904, from highwater marks.

Remarks. Reservoir is formed by concrete dam at outlet of natural lake completed in 

1921, which replaced a temporary dam built in 1919; storage began Apr. 15, 1919. 

Capacity, 584,000 acre-ft between elevations 4,135.0 and 4,143.3. ft. Dead storage below elevation 4.135 ft not known; lake level ordinarily maintained between 

elevations, 4,137 ft (contents, 118,600 acre-ft) and 4,143.3 ft. Water stored 

may be diverted through "A" Canal for irrigation of land under Klamath project of 

Bureau of Reclamation, or released to Link River through dam or powerplants at 

Klamath Falls. Area of lake at high stages is partly controlled by diking. Lake 

elevations, particularly extremes, are very much affected by wind.

determined from gage-height graph based on gage readings and shape of graph for 

Payette Lake at McCall.

Maxima. December 1955 to January 1956: Contents observed, 302,800 acre-ft Jan. 30, 

5F~(elevation, 4,809.37 ft); rate of inflow about 11,000 cfs about 12 m. to 

4 p.m. Dec. 22.

1948 to November 1955: Contents observed, 405,100 acre-ft June 20, 1953 (elevation, 4,815.01 ft).

Remarks. Reservoir is formed by earthfill dam completed in May 1949. Storage 

began Nov. 7, 1947. Capacity, 703,200 acre-ft between elevations 4,766 ft 

(4.0 ft above sill of outlet tunnel) and 4,828 ft (top of spillway gates). 

Figures herein show contents above elevation 4,766 ft. The Bureau of Reclamation plans to limit withdrawal to elevation 4,787.5 ft, retaining 50,000 acre-ft 

capacity as dead storage. Contents table computed from tables furnished by 

Bureau of Reclamation (revised 1950). Water is used for irrigation of lands in 

the Payette Division of the Boise project and for power at Black Canyon powerplant near Emmett.
