SURFACE WATER SUPPLY OF PACIFIC SLOPE BASINS IN CALIFORNIA, 193S

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 tte water year 

ending September 30, 1939. The work was begun in 1888 in connection with special studies 

relating to irrigation. Measurements of flow of streams and measurements of stage and contents of lakes and reservoirs have been made at about 8,240 gaging stations Ir the United 

States and also at many gaging stations In Alaska and Hawaii. In July 1939, 4,160 gaging 

stations were being maintained by the Geological Survey and cooperating organizations. 

Miscellaneous discharge measurements were made at many other points.

In the execution of the work many State and private organizations have cooi^rated, 

either by furnishing data or by assisting in collecting data. Acknowledgments' for cooperation of the first kind are made In connection with the description of each station 

affected; cooperation of the second kind is acknowledged on page 9.

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-feet" Is an abbreviation for "cubic feet per second." A second-foct is the rate 

of discharge of water flowing in a channel when the cross-sectional area is 1 square foot 

and the 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 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 its surface. It is used 

for comparing run-off with rainfall, which is usually expressed in inches.

An "acre-foot," equivalent to 43,560 cubic feet, is the quantity of water required to 

cover an acre to the depth of 1 foot. The term is commonly used in connectior 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 run-off of 0.0372 inch from one square mile.

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

discharge."

"Control" Is a term used to designate the natural section or reach of the channel or 

artificial structure below the gage that determines the stage-discharge relation at the

EXPLANATION OF DATA

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

1
2 EXPLANATION OF DATA

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

direct readings on a nonrecordlng 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 gaging stations, equipped with water-stage recorder and measuring 

cable and car, are shown on plate 1.

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

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

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

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

and a table of monthly and yearly discharge and run-off. Skeleton rating tables are published except for those stations whose 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, its latitude and longitude determined from the best available maps, and information in regard to diversions that 

decrease the flow at the gage, artificial regulation from pondage or storage, and the 

accuracy of the records. Under "Average discharge" Is given the averafe discharge for the 

number of years indicated. It is given only for stations for which there are 10 or more 

complete years of record. Under "Extremes" are given the maximum disci:arge and gage 

height; the minimum discharge if there is little or no regulation; the minimum daily discharge If there is extensive regulation (also the minimum discharge If useful); and the 

minimum gage height (except when it is of no importance). Unless otherwise qualified, the 

maximum discharge corresponds to the crest stage, obtained by use of e water-stage recorder 

or a nonrecordlng gage read at the time of the crest. Likewise the mlrimum represents the 

lowest discharge, unless otherwise qualified. The peak discharge for the year with the 

time of its occurrence Is given below the table of monthly discharge fcr some stations. 

Selected lower peaks are also given if the peak discharge exceeded the mean discharge for 

that day by more than 10 percent. This supplementary information is generally not given 

for stations having drainage areas of less than 10 square miles or more than 10,000 square 

miles.

The table of daily discharge gives, for stations equipped with nonrecording gages, the 

discharge In second-feet corresponding to once-daily readings of the gfge or the mean of 

twice-daily readings. For flashy floods the mean dally discharge is determined from gageheight graphs based on gage readings made once or twice dally or oftener, as stated In the 

station description. 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 mean dally gage height. For stations subject to such fluctuation the mean daily 

gage height may not indicate the true mean dally discharge, which must be obtained by 

averaging the discharge for intervals of the day or by using the dischrrge Integrator, ar 

instrument for obtaining the mean daily discharge from a continuous gage-height graph and 

containing as an essential element the rating curve of the station.

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

for each month of the figures for that month given In the table of daily discharge. The 

column headed "Maximum" gives the maximum dally discharge and not the discharge when the 

water surface was at crest height. Likewise, In the column headed "Mirimum" the quantity

given Is the minimum dally discharge. The column headed "Mean" gives the average flow in 

cubic feet per second during the month.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of stream-flow data depends primarily on (1) the permanency of the stagedischarge relation and (2) the accuracy of observation 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 dally records are accurate within 5 

percent; "good," within 10 percent; "fair," within 15 percent; and "poor," vlthin 20 or a 

higher percent.

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

owing to diversions, amount consumed, 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 "run-off In Inches" are not published unless reservoir 

records are included indicating the extent of the regulation, or satisfactory adjustments 

can be made for changes In contents of reservoirs or for other changes incident to use and 

control. Figures of second-feet per square male and run-off in inches are also omitted If 

the drainage area includes large noncontrlbuting areas or if the average annual rainfall 

over the drainage area is less than 20 inches.

Many gaging stations on streams in the Irrigated areas of the United States are situated above most of the diversions from those streams, so that 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 gives a general idea of the flow at the station. The 

table of daily discharge allows 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, and that greater degrees of refinement in 

computations and records may be warranted with the Increase In data and the use of improved 

equipment.

southeast of Stratford.

Records available.- May 1937 to September 1939. 

plete), at several other sites.

March 1906 to September 1920 (incoms,- Maximum stage recorded during year, 191.0 feet Feb. 17-27. 

jJo"6-39: Maximum stage probably occurred June 21, 1907 (gage height, 14.0 feet, 

former site and datum); lake dry or practically so during parts of 1906, 1914, 1916, 

1919, each year of 1920-22, and 1924-36, and 1937.

Remarks.- Tulare Lake receives water from Kings, Kaweah, and Tule Rivers during hlghwater periods and occasionally from Kern River, Deer Creek, and several small intermittent streams. Its boundaries nave been greatly altered In recent years by construction of levees and other reclamation work. Water reached lake from tributaries 

about Feb. 10, 1937, for first time since April 1923, and lake attained a stage of 

192.3 feet June 16, 1937 (contents, about 420,000 acre-feet). It then receded until 

Dec. 14, 1937, when flow from flood of Dec. 11 was received. Slowly rising stage continued through March 1938, except for occasional levee breaks, which caused stage to 

fall and storage to Increase. The spring rise began about Apr. 15, 1938, and continued until June 5, 1938, when peak was reached. Amount of water in storage continued to Increase, due to more levee breaks, until June 30, 193S. Since then, the 

trend has been downward, with slight fluctuations during 1939 caused by pvmplnp; Into 

and out of lake. Gage-height record obtained under supervision of Roy L. May and 

furnished by Tulare Lake Reclamation District No. 749.

288 FEATHER RIVER BASIN

Bowman Lake near Granltevllle, Calif.

Location.- Staff gage, lat. 39°27', long. 120°39', In SWi sec. 5, T. 18 N., R. 12 E.. at 

Bowman Dam on Canyon Creek, 4 miles east of Granltevllle. Zero of gage Is 5,000.0 

feet above mean sea level.

Drainage area.- 30 square miles.

Records available.- December 1926 to September 1939.

Extremes.- Maximum contents during year, 50,600 acre-feet Oct. 1 (elevation, 5,541.0 

feet); minimum, less than 1,000 acre-feet and therefore doubtful Mar. 3-25 (minimum 

elevation recorded, 420.0 feet Mar. 20-23).

1926-39: Maximum contents, 70,500 acre-feet June 16, 17, 1937 (elevation, 5,565.9 

feet); minimum, less than 1,000 acre-feet and therefore doubtful at times during 1926, 

1928-31, 1933-35, 1937, 1939.

Remarks.- Lake Is formed by one rock-fill and one concrete-arch dam; storage began In 

November 1926. Usable capacity, 68,200 acre-feet between elevations f,000 feet 

(bottom of outlet tunnel) and 5,563 feet (crest of concrete dam) above'mean sea level. 

Flashboards occasionally added, increasing elevation to 5,564.5 feet and capacity to 

69,400 acre-feet. Lake receives water from Middle Fork of Tuba River through MiltonBowman tunnel and releases it through Bowman-Spaulding canal to reservoirs of Pacific 

Gas and Electric Co. Water is eventually used for irrigation by Nevada Irrigation 

District (see pp. £84,290). Record of daily gage readings, made at odd times, furnished 

by Nevada Irrigation District. Records show contents at times of gage readings, all 

of which is available for release.

AMERICAN RIVER BASIN

Silver Lake outlet near Klrkwood, Calif.

Location.- Water-stage recorder, lat. 38°40', long. 120°08', in SWi sec. 32, T. 10 N., 

R. 17 E., 1,000 feet downstream from Silver Lake Dam and 3 miles southwest of Kirkwood. 

Altitude, about 7,200 feet.

Drainage area.- 14,9 square miles.

Records available.- September 1922 to September 1939.

Average discharge.- 17 years, 29.7 second-feet.

Extremes.- Maximum discharge during year, 121 second-feet Apr. 18 (gage height, 2.31 feet); 

minimum, 0.1 second-foot Jan. 7-9.

1922-59: Maximum discharge, 504 second-feet Dec. 11, 1937 (gage height, 5.10 feet), 

from rating curve extended above 190 second-feet; minimum, 0.1 second-foot during 

periods when reservoir gate was closed.

Remarks.- Records excellent except those for periods of ice effect, Ja". 5, 6, Jan. 13 to 

Feb. 16, Feb. 23 to Mar. 12, which were computed on basis of gage-height graph and 

weather records at Twin Lakes and are fair. Storage in Silver Lake was 3,420 acre-feet 

on Sept. 30, 1938, and 3,520 acre-feet on Sept. 30, 1939. In addition to water released 

through darp and over spillway, some water escapes from Silver Lake through porous rock 

formation. The discharge at this station combined with seepage froii Silver Lake near 

Kirkwood (see following page) represents practically entire outflow from Silver Lake. 

Gage-height record and resalts of three discharge measurements furnished by Pacific 

Gas & Electric Co.

AMERICAN RIVER BASIN 305

Seepage from Silver Lake near Klrkwood, Calif.

Location.- Staff gage, lat. 38°40', long. 120°07', In SWi sec. 32, T. 10 N., R. 17 E., 

Just upstream from road crossing and half a mile northeast of Silver Lake Darn. 

Altitude, about 7,800 feet.

Records available.- October 1929 to September 1939. 

Average discharge.- 10 years, 3.74 second-feet.

Extremes.- Maximum discharge observed during year, 15 second-feet Hay 11 to June 5; no 

flow during most of year.

1929-39.: Maximum discharge observed, 25 second-feet June 9, 1930; no flow during 

most of each year.

Remarks.- Records good. Gage read once dally. No flow when Silver Lake gage height Is 

below 14.0 feet. This Is a record of largest amount of seepage from Silver Lrke 

through porous rock formation; other seepage from Silver Lake Is of little or no 

consequence. The discharge at this station combined with that for Silver Lake outlet 

near Klrkwood (see preceding page) represents practically entire outflr~T from Silver 

Lake. Gage-height record and results of two discharge measurements furnished by 

Pacific Gas & Electric Co.

YEARLY-DISCHARGE SUMMARY

The summaries contained In the following tables give In convenient form for general 

reference and for use in preliminary Investigations the figures of yearly discharge and 

run-off for certain gaging stations in the Pacific slope basins in California. All gagIng stations, both active and discontinued, at which 10 or more complete years of record 

have been collected are represented, also some special stations, as noted below. The 

summaries present figures of maximum and minimum daily discharge and mean discharge, in 

second-feet, and run-off, In acre-feet, for both the water years ending September 30 and 

the calendar years. The figures for the water years prior to 1912 and figures for the 

calendar years 1312 to 1933 have not been previously published In the annual water-supply 

papers but are included in these summaries.

The number of the water-supply paper in which the figures of daily and monthly discharge as well as yearly discharge ar^ published Is shown In the column headed W.S.P.(no. 

and page). The descriptions contained In the water-supply papers indicated give detailed 

information relative to the gaging stations, including location, diversions, regulation 

by storage, and otner pertinent information.

Summaries for Incomplete years are given for those stations In irrigated regions for 

which seasonal records were collected in order to show the flow available for irrigation. 

An incomplete year is included for other stations If the maximum dally discharge or minimum dally discharge for all the years of record occurred In that year.

These summaries include canal records that are supplementary to records for river stations. They also include records of contents of some reservoirs that materially affect 

stream flow.

Former names under which records for sorie of the stations have been published In the 

annual water-supply papers are Indicated in these yearly summaries as follows;

1. If the name of the stream or town or other feature to which the station is referred has been changed, the former name Is given In parentheses, indicating that records 

for some of the earlier years are published under the obsolete name.

2. If the entire name of z. station has been changed, the superseded name and years 

when It was used are given In parentheses beneath the present name.
