SURFACE WATER SUPPLY OF PACIFIC SLOPE 

BASINS IN CALIFORNIA, 1930

AUTHORIZATION AND SCOPE OF WORK

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

measurements of flow made on streams in the United States during 

the year ending September 30, 1930.

The data presented in these reports were collected by th"* 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. Since the fiscal year ending June 30, 1895, 

successive appropriation bills passed by Congress have carried the 

following items;

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

and for the investigation of underground currents and artesian well", and for 

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

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

collecting data. Acknowledgments for cooperation of the f rst kind 

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

cooperation of the second kind is acknowledged on page 10.

Measurements of stream flow have been made at abo^t 6,070 

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

the Hawaiian Islands. In July, 1930, 2,430 gaging stations were 

being maintained by the Geological Survey and the cooperating 

organizations. Many miscellaneous discharge measurements were
2 SURFACE WATER SUPPLY, 1930, PART 11

made at other points. In connection with this work data were also 

collected in regard to precipitation, evaporation, storage reservoirs, 

river profiles, and water power in many sections of the country and 

will be made available in 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 whbh 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, miner's inches, and discharge in second-feet 

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

water, as run-off in inches, acre-feet, and millions of cubic feet. The 

principal terms used in this series of reports are second-feet, secondfeet per square mile, run-off in inches, and acre-feet. They may be 

defined as follows:

"Second-feet" is an abbreviation for "cubic feet p^r 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 cf area drained, 

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

regards time and area.

"Kun-off in inches" is the depth to which an aref. 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 inches.

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

required to cover an acre to the depth of 1 foot. The term 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 "relation 

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 determines 

the stage-discharge relation at the gage.

EXPLANATION OF DATA

The data presented in this report-cover the year beginning October 1, 1929, and ending September 30, 1930. At the beginning of 

January in most parts of the United States much of the precipitation in the preceding three months is stored in the form of snow or 

ice, or in ponds, lakes, and swamps, or as undergro^ind water, and
EXPLANATION OF DATA O

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

At the end of September, on the other hand, the only storedjwater 

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

derived from precipitation within that year.

The base data collected at gaging stations consist of records of 

stage, measurements of discharge, and general information used to

FIGUEE 1. Typical river-measurement station showing concrete well and house for water-stage recorder

and staff gages, cable, and car

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 witn a current meter by the general 

methods outlined in standard textbooks on the measurement of 

river discharge. A typical gaging station, equipped with water-stage 

recorder and measuring cable and car, is shown in Figure 1.
4 SURFACE WATER SUPPLY, 1930, PART 11

From the discharge measurements rating tables are prepared that 

give the discharge for any stage. The application of the daily gage 

height to these rating tables gives the daily discharge from which 

the monthly and yearty mean discharge is computed.

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

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

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

discharge and run-off.

The description of the station gives, in addition to statements regarding location and type of gage, information as to diversions that 

decrease the flow at the gage, artificial regulation, maximum and 

minimum recorded discharge, and the accuracy of the records. The 

maximum discharge given under "Extremes" does not represent the 

crest discharge unless a water-stage recorder was in operation or unless 

a nonrecording gage was read at the time of the crest.

The table of daily discharge gives, in general, the discharge in second-feet corresponding to the daily gage height, which may be a once 

daily reading or the mean of twice daily readings of a nonrecording 

gage or the mean daily gage height obtained from a water-stage 

recorder graph.

At stations on streams subject to sudden or rapid diurnal fluctuation the discharge obtained from the rating table and the mean daily 

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

stations are equipped with water-stage recorders, the mean daily discharge may be obtained by averaging discharge at regular intervals 

during the day or by using the discharge integrator, an instrument 

for obtaining 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 "Maximum" 

gives the maximum daily discharge, and not the discharge when the 

water surface was at crest height. Likewise, in the column headed 

"Minimum" the quantity given is the minimum daily discharge. 

The column headed "Mean" is the average flow in cubic feet per 

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

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

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

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

of observation of stage, measurements of flow, and interpretation of 

records.

The station description gives *a statement in regard to the general 

accuracy of the records. "Excellent" indicates that records are 

accurate within 5 per cent; "good," within 10 per cent; "fair," 

within 15 per cent; and "poor," within 20 per cent or more.

r

The monthly means for any station may represent with high 

accuracy the quantity of water flowing past the gage, but the figures 

showing discharge per square mile and run-off in inches may be subject to gross errors caused by the inclusion of large noncontributing 

districts in the measured drainage area, by lack of information concerning water diverted for irrigation or other use, or by inability to 

interpret the effect of artificial regulation of the flow of the rivr 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.

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.

Many gaging stations on streams in the irrigated areas 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 

stations must first be satisfied.

Investigations 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 f ow, but 

it has comprised also investigation of such closely allied sul jects as 

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

quality of waters. Most of the results of these investigation 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 boundar°.s coincide with natural drainage features, as indicated below:

Part 1. North Atlantic slope basins (St. John to York River).

2. South Atlantic slope and eastern Gulf of Mexico basins (Janes River 

to the Mississippi).

3. Ohio River Basin.

4. St. Lawrence River Basin.

5. Hudson Bay and upper Mississippi River Basins.

6. Missouri River Basin. '

7. Lower Mississippi River Basin.

8. Western Gulf of Mexico basins.

8 SUBFACE WATER SUPPLY, 1930, PART 11

The records at most of the stations discussed in these reports 

extend over a 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 in the same relative order as th^ regular gaging 

stations. 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 t asins, the numbers of the papers on surface-water supply published from 1899 to 

1930. The data for any particular station will be fouri in the reports 

covering the years during which the station was maintained. For 

example, data from 1910 to 1920 for any station in t*ie area covered 

by Part 3 are published in Water-Supply Papers 28", 303, 323, 353, 

383, 403, 433, 453, 473, and 503, which contain recoHs for the Ohio 

River Basin for those years.

COOPERATION

Investigation of the water resources of California is being carried 

on by the United States Geological Survey in cooperation with the 

State in accordance with acts of the State legislature, approved 

March 16, 1903, March 20, 1905, March 11, 1907, and April 22,1909, 

empowering the State authorities to enter into contracts with the 

Director of the United States Geological Survey for the purpose of 

making topographic maps, gaging streams, and surveying reservoir 

sites and canal locations for the conservation and utilization of the 

flood and storm waters of the State. The State fttn^s for the work 

during the year 1930 were provided for in the State budget and the 

usual agreement was executed by B. B. Meek, director of public works, 

and Edward Hyatt, State engineer.

The entire expense of the stream-flow investigations in the Tuolumne River Basin for the Hetch Hetchy project is paid by the city 

and county of San Francisco, through M. M. O'Shaughnessy, 

city engineer.

All stations in Los Angeles County are maintainec1 in cooperation 

with the board of supervisors and the Department of Agriculture, 

represented by the Forest Service through E. W. Framer, district 

engineer, and by the Weather Bureau through H. B. Hersey, meteorologist. The Forest Service pays the salary and expenses of a 

hydrographer detailed for field work. The Geological Survey supervises the work and compiles all stream-flow data for publication.

The stations in the Santa Ana River Basin are maintained in cooperation with San Bernardino, Riverside, and Orange Counties 

through their boards of supervisors. Cooperation if also furnished 

by the Weather Bureau in maintaining precipitation stations.

Assistance in the maintenance of the river-measurement stations 

was furnished by the Southern California Edison Co., San Joaquin 

Light & Power Corporation, Pacific Gas & Electric Co., Snow 

Mountain Water & Power Co., Merced Irrigation District, Southern 

Sierras Power Co., East Bay Municipal Utility District, and other 

permittees and licensees of the Federal Power Commission.

The work in Oregon was carried on under cooperative agreement 

between the United States Geological Survey and the State of Oregon 

through Rhea Luper, State engineer. Financial assistance was furnished by the California Oregon Power Co.

Acknowledgment is due also to the Corps of Engineers, United 

States Army, for financial assistance in collecting records published 

herein.
