SUKFACE WATEE SUPPLY OF PACIFIC SLOPE 

BASINS IN CALIFOENIA, 1934

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, 1934.

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. 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 wells, 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 first 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 about 6,900 points 

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

Hawaiian Islands. In July 1934, 2,940 gaging stations were being 

maintained by the Geological Survey and the cooperating organiza1 Only $340,000 available for expenditure. 1

tions. Many miscellaneous discharge measurements were 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 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, 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", "second-feet per square mile", "run-off in inches", 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 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, 1933, and ending September 30, 1934. At the beginning of January in most parts of the United States much of the precipitation in the 

preceding 3 months is stored in the form of snow or ice, or in ponds,
EXPLANATION OF DATA 3

lakes, and swamps, or as underground water, and this stored water 

passes off in the streams during the spring break-up. At the end of 

September, on the other hand, the only stored water 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 the 

precipitation within that year.

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

and staff gages, cable, and car.

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 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
4 SURFACE WATER SUPPLY, 1934, PART 11

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.

Rating tables giving the discharge for any stage are prepared from 

the discharge measurements. The application of the daily gage 

heights to these rating tables gives the daily discharge from which the 

monthly and yearly mean discharge is computed.

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

this report usually comprise a description of the station and a table 

showing the daily discharge of the stream, and the monthly and 

yearly discharge and run-off.

The description of the station gives information in regard to the 

location and type of gage, 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 average discharge 

for the number of years indicated. It is given only for stations for 

which there are 10 or more complete years of record. Information 

under "Extremes" gives 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, and 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 a water-stage 

recorder or a nonrecording gage read at the time of the crest. Likewise the minimum represents the lowest discharge unless otherwise 

qualified.

The table of daily discharge gives, for stations equipped with nonrecording gages, the discharge in second-feet corresponding to oncedaily or the mean of twice-daily readings of the gage. For stations 

equipped with water-stage recorders the table gives the discharge corresponding to the mean daily gage height except for stations on streams 

subject to sudden or rapid fluctuation. For stations subject to such 

fluctuation the mean daily gage height may not indicate the true mean 

daily discharge, which must be obtained by averaging the discharge 

for intervals of the day or by using the discharge integrator, an instrument for obtaining the mean daily discharge from a continuous gageheight 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.
SUEFACE WATER SUPPLY, 1934, PART 11 5 

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 records. "Excellent" indicates that, in general, the daily 

records are accurate within 5 percent; "good", within 10 percent; 

"fair", within 15 percent; and "poor", within 20 percent or more.

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 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.

Many gaging stations on streams in the irrigated areas of the 

United States are situated 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.

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 

increased data and use of improved equipment.

In order to permit greater refinement in analysis and comparison 

of records for adjacent stations, the following changes have been 

made in the computation procedure: (a) Mean monthly discharge 

above 1,000 second-feet and monthly run-off above 10,000 acre-feet 

are expressed to four significant figures instead of three significant figures 

as formerly; (6) monthly run-off in acre-feet is computed from the 

total second-foot-days for the month and not from the mean discharge 

for the month; (c) drainage areas above 1,000 square miles, if measured on topographic maps or if otherwise warranted, are expressed to 

four significant figures instead of three as formerly. Some of the 

records in the series of reports for 1934 have been computed in accordance with the modified procedure.

PUBLICATIONS

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

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

Mississippi River).

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.

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 the 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 basins, the numbers of the papers on surface-water supply published from 1899 to 

1934. The data for any particular station will, as a rule, be found in 

the reports covering the years during which the station was maintained. For example, data from 1910 to 1920 for any station in the 

area covered by part 3 are published in Water-Supply Papers 283, 

303, 323, 353, 383, 403, 433, 453, 473, and 503, which contain records 

for the Ohio River Basin for those years.

SAN GABRIEL RIVER BASIN 65

San Gabriel River near Azusa, Calif.

Location.- Water-stage recorder in NWJ sec. 23, T. IN., R. 10 W., 1 mile above Southern California Edison Co.'s power house and 2 miles north of Azusa.

Drainage.- 214 square miles.

Records available.- 1894 to September 1934.

Average discharge.- 38 years (1896-1934), 106 second-feet at gage. Average combined 

discharge of river and diversions, corrected for storage and evaporation In 

Morris Reservoir, 39 years (1895-1934), 151 second-feet.

Extremes.- Maximum discharge during year, 6,120 second-feet Jan. 1 (gage height, 6.92 

feet); no flow for long periods.

1894-1934: Maximum discharge, 40,000 second-feet Jan. 18, 1916 (gage height, 

12.0 feet); no flow for several months each year.

Remarks.- Records good. Some discharge measurements furnished by Los Angeles County 

Flood Control District and Pasadena Water Department. Morris Reservoir of 

Pasadena Water Department was placed In operation during year; capacity, 39,350 

acre-feet. Azusa Canal (formerly power canal of Southern California Edison Co.) 

diverts about 5 miles above station, also above high-water line of Morris Reservoir. Sum of discharge In river at gage, Azusa Canal, storage released to city 

of Pasadena, and reservoir evaporation (see next page) gives total run-off comparable to combined discharge of San Gabriel River and Southern California Edison 

Co.'s canal as published In 1894-1933.
