SURFACE WATER SUPPLY OF PACIFIC SLOPE 

BASINS IN CALIFORNIA, 1923

AUTHORIZATION AND SCOPE OF WORK

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

measurements of flaw made on streams in the United States during 

the year ending September 30, 1923.

The data presented in these reports were collected by the United 

States Geological Survey under authority contained in the organic 

law (20 Stat. L. p. 394), which contains the following paragraph:

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 

of water supply for 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 this work many private and State organizations have cooperated, 

either by furnishing records or by assisting in their collection. 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 5.

Measurements of stream flow have been made at about 5,600 

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

the Hawaiian Islands. In July, 1923, 1,590 gaging stations were

1
2 SURFACE WATEK SUPPLY, 1923, PAET XI

being maintained by the Survey and the cooperating organizations. 

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. Information in 

regard to publications relating to .water resources is presented in the 

appendix to this report.

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 certain5 class of work. These terms may be divided 

"into two groups (1) those that represent a rate of flow, as secondfeet, gallons per minute, miners' 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 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 depth 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 section or sections of the 

stream channel below the gage which determine the stage-discharge 

relation at the gage. It should be noted that the control may not 

be the same section or sections at all stages.

The "point of zero flow" for a gaging station is that point on the 

gage the gage height at which water ceases to flow over the control.
SUBFACE WATEK SUPPLY, 1923, PABT XI 3 

EXPLANATION OF DATA

The data presented in this report cover the year beginning October 

1, 1922, and ending September 30, 1923. At the first of January 

in most parts of the United States much of the precipitation in the 

preceding three months is stored as ground water, in the form of 

show or ice, or in ponds, lakes, and swamps, 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 

precipitation within that year.

The base data collected at gaging stations consist of records of 

stage, measurements of discharge, and general information used to

FIGURE 1. Typical gaging station

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 with a current meter. The general methods are 

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.

From the discharge measurements rating tables are prepared that 

give the discharge for any stage. 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 comprise a description of the station, a table giving
4 SURFACE WATER SUPPLY, 1923, PART XI

 results of discharge measurements, a table showing the daily discharge of the stream, and a table of monthly and yearly discharge 

and run-off.

If the base data are insufficient to determine the daily discharge, 

tables giving daily gage height and results of discharge measurements are published.

The description of the station gives, in addition to statements 

regarding location and equipment, information in regard to any 

conditions that may affect the permanence of the stage-discharge 

relation, covering such subjects as the occurrence of ice, the use of 

the stream for log driving, shifting of control, and the cause and 

effect of backwater. It gives also information as to diversions that 

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

minimum recorded stages, and the accuracy of the records.

The table of daily discharge gives the discharge in second-feet 

corresponding to the mean of the gage heights read each day. At 

stations on streams subject to sudden or rapid diurnal fluctuations 

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-gage 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 operating on the principle of the planimeter and containing 

as an essential element the rating curve of the station.

In the table of monthly discharge the column headed "Maximum" 

gives the mean flow for the day when the mean gage height was highest. As the gage height is the mean for the day it does not indicate 

correctly the stage when the water surface was at crest height and 

the corresponding discharge was consequently larger than given in 

the maximum column. Likewise, in the column headed "Minimum " 

the quantity given is the mean flow for the day when the mean gage 

height was lowest. The .column headed "Mean" is the average 

flow in cubic feet per second during the month. On this average 

flow computations recorded in the remaining columns, which are 

defined on page 2, are based.

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.

A paragraph in the description of the station gives information 

regarding the (1) permanence of the stage-discharge relation, (2) 

precision with which the discharge rating curve is defined, (3) refine-
COOPERATION P

ment of gage readings, (4) frequency of gage readings, and (5) 

methods of applying daily gage height to the rating table to obtain the 

daily discharge.

For the rating curves "well defined" indicates, in general, that the 

rating is probably accurate within 5 per cent; "fairly well defined/' 

within 10 per cent; "poorly defined," within 15 to 25 per cent. 

These notes are very general and are based on the plotting of the 

individual measurements with reference to the mean rating curve.

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. All figures 

representing "second-feet per square mile" and "run-off in inches" 

published in the earlier reports by the Survey, should be used with 

caution because of possible inherent sources of error not known to 

the Survey.

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. To give an idea of the amount of prior appropriations, a paragraph on diversions is presented in each station 

description. The figures given can not be considered exact but 

represent the best information available.

The tables of monthly discharge give only a general idea of the 

flow at the station and should not be used for other than preliminary 

estimates; the tables of daily discharge allow 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.

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 2Q, 1905, March 11, 1907, and April 22, 1909,

sites and canal locations for the conservation and utilization of the 

flood and storm waters of the State. The work for the year 1923 

was maintained in accordance with the contract signed by W. F. 

McClure, State engineer. Additional funds for the maintenance of 

river-measurement stations were furnished by the division of water 

rights, Department of Public Works of the State of California, 

through H. A. Kluegel, chief of the division during the year.

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 maintained in cooperation with the Board of Supervisors, the Department of Agriculture, 

represented by the Forest Service through F. H. Fowler and F. E. 

Bonner, district engineers, and the Weather Bureau through H. B. 

Hersey, meteorologist. Los Angeles County pays the cost of the 

field work except for the services and expenses of one hydrographer 

furnished by the Forest Service. The Geological Survey supervises 

the work and compiles all stream-flow data for publication.

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

their boards of supervisors. Cooperation is also furnished by the 

Weather Bureau in maintaining precipitation stations.

Assistance in the maintenance of river-measurement stations was 

furnished by Southern California Edison Co., San Joaquin Light & 

Power Corporation, Pacific Gas & Electric Co., Western States 

Gas & Electric Co., Snow Mountain Water & Power Co., Ed Fletcher, 

and Southern Sierras Power Co.

Many complete records of run-off, gage-height records, and discharge measurements are furnished by various Federal bureaus, 

private companies, and individuals who are interested in the water 

resources of California. This cooperation is acknowledged and 

explained in the descriptions that precede the records.

The work in Oregon was carried on under a cooperative agreement 

with the State through Percy A. Cupper and Rhea Luper, State 

engineers. Financial cooperation was furnished by the United States 

Bureau of Reclamation, United States Office of Indian Affairs, The 

California-Oregon Power Co., Talent irrigation district, and Fort 

Elamath Meadows Co.

station at old Mission Dam.

RECORDS AVAILABLE. May 25, 1912, to September 30, 1923 (record not complete). Previous to November 10, 1920, station was at old Mission Dam.

GAGE. Water-stage recorder on right bank installed November 10, 1920.

DISCHARGE MEASUREMENTS. Made from cable just above gage or by wading.

CHANNEL AND CONTROL. Solid rock formation forces ground water to surface 

above dam. The old Loop Dam serves as part control.
SAN DIEGO KIVEK BASIN 9

EXTREMES OP DISCHARGE. Maximum stage during year, from water-stage 

recorder, 1.70 feet at 11 a. m. December 14 (discharge, 360 second-feet); 

stream practically dry during summer.

1912-1923: Maximum stage recorded, 25.1 feet January 27, 1916 (discharge, 70,200 second-feet); stream practically dry for several months each 

year except for a small amount of ground water forced to surface by rock 

formation.

DIVERSIONS. See Cuyamaca Water Co.'s flume near Lakeside. Water for 

irrigation is pumped from wells along the river above and below Lakeside.

REGULATION. Water is stored at Cuyamaca Reservoir on Boulder Creek.

ACCURACY. Stage-discharge relation changed slightly from time to time on 

account of sand on control. Standard rating curve well defined to 2,500 

second-feet and extended above. Water-stage recorder gave excellent gageheight record. Daily discharge ascertained by shifting-control method 

estimated May 20 to 25. Records good/

CUYAMACA WATER GO.'S FLUKE AT DIVERTING DAM, NEAR LAKESIDE, CALIF.

LOCATION. In SE. J^ sec. 11, T. 14 S., R. 2 E., at diverting dam on San Diego

River, 13 miles northeast of Lakeside, San Diego County. 

"RECORDS AVAILABLE. June 1, 1912, to September 30, 1923.

 GAGE. Vertical staff in a stilling box on outside of flume, about l',000 feet 

below intake, installed October 15, 1919. Previous gages were at approximately same location. Datum has always been elevation of floor of flume. 

Gage read by employees of Cuyamaca Water Co.

DISCHARGE MEASUREMENTS. Made from foot plank across flume at gage.

'CHANNEL AND CONTROL. The flume is 6 feet wide, 24 inches deep, and lined 

with tar paper to reduce leakage.

.EXTREMES OP DISCHARGE. 1912-1923: Maximum mean daily discharge, 51 

second-feet, March 24, 1913. No flow for periods nearly every year.

.ACCURACY. Stage-discharge relation did not change during the year. Rating 

curve well defined. Gage read to hundredths three times a day. Daily 

discharge ascertained by applying mean daily gage height to rating table. 

Records good.

 COOPERATION. Gage-height record and results of discharge measurements 

furnished by Cuyamaca Water Co., Ed. Fletcher, manager.

Cuyamaca Water Co.'s flume, which diverts water from San Diego River 

'below the mouth of Boulder Creek and receives water from the South Fork

 of San Diego River, is more than 30 miles long and discharges into Eucalyptus 

Reservoir near Grossmont. Water is stored in Cuyamaca Reservoir on Boulder

 Creek and released down the natural channel of Boulder Creek and San Diego 

River during low-water periods. A small amount of water is used in the vicinity

 of Eucalyptus Reservoir and the remainder carried by La Mesa ditch to Murray 

Reservoir, formerly called La Mesa Reservoir, about 8 miles northeast of 

San Diego. The flume supplied the city of San Diego with water until 1906, 

when the Southern California Mountain Water Co. extended its system to 

the city. The flume was again used to supply the city of San Diego after 

the floods of 1916, and it now supplies water for irrigation and domestic 

use. The Capitan Grande Indian Reservation has a water right of 0.8 second 

tfoot from this flume.

Coches Creek, 3 miles southeast of Lakeside, San Diego County, and 20 

miles below intake on San Diego River.

RECORDS AVAILABLE. January 1, 1907, to September 30, 1,923.

GAGE. Vertical staff in a stilling box fastened to outside of flume at same site 

as water-stage recorder used November 12, 1912, to June 30, 1915. Position of gage has been changed slightly several times since station was first 

established, but datum has always been same as elevation of floor of flume. 

Gage read by an employee of Cuyamaca Water Co.

DISCHARGE MEASUREMENTS. Made from foot plank across flume near gage.

CHANNEL AND CONTROL. In fall of 1914 the flume was deepened 8 inches and 

more tar-paper lining was put in. Capacity of flume was slightly increased 

as a result of repairs made December 1-19, 1917, December 7-19, 1918, and 

considerably increased after relining in latter part of 1921.

EXTREMES OP DISCHARGE. 1907-1923: Maximum mean daily discharge, 31 

second-feet June 13, 1922. No flow at times nearly every year.

ACCURACY. Stage-discharge relation did not change during year. Rating curve 

fairly well defined. Gage read to hundredths three times daily. Daily 

discharge ascertained by applying mean daily gage height to rating table, 

except for a few scattered days of no record for which it was interpolated 

or estimated by Cuyamaca Water Co. Records good.

COOPERATION. Gage-height record and results of most of the measurements 

furnished by Cuyamaca Water Co., Ed. Fletcher, manager.

There is a small diversion from this flume at Capitan Grande Indian Reservation above the station. Water is also diverted into the flume from South 

Fork of San Diego River. For location of intake, description of flume, and explanation of the use of the water, see description of Cuyamaca Water Co.'s flume 

at diverting dam near Lakeside, page 13.

SANTA ANA EIVER BASIN 33

SAHTA AHA RIVER NEAR PRADO, CALIF.

LOCATION. At Riverside-Orange County line in lower Santa Ana Canyon, 

3 miles by river below Rincon bridge, and 3 miles southwest of Prado, 

Riverside County.

DRAINAGE ABEA. Not measured.

RECORDS AVAILABLE. January 31, 1919, to September 30, 1923.

GAGE. Water-stage recorder, in concrete well and house, on left bank.

DISCHARGE MEASUREMENTS. Made from cable 500 feet above gage. At low 

stages measurements are made from temporary footbridge at cable or by 

wading.

CHANNEL AND CONTROL. Bed is shifting sand. Banks are low and subject 

to overflow at high stages; channel about 800 feet wide at extreme flood 

stages. Right bank covered with trees and brush; left bank has trees and 

brush along bank of low-water channel.

EXTREMES OP DISCHARGE. Maximum stage during year, from water-stage 

recorder, 3.90 feet at 2.30 a. m. December 14 (discharge, 1,080 second-feet); 

minimum discharge, from water-stage recorder, 53 second-feet at 11.30 p. m. 

July 26, gage height, 0.10 foot.

1919-1923: Maximum stage, from water-stage recorder, 5.45 feet at 

3 a. m. February 23, 1920 (discharge, about 7,560 second-feet); minimum 

discharge, 41 second-feet, at 8 p. m. July 15, 1919, gage height from waterstage recorder, 1.21 feet.

DIVERSIONS. Numerous water companies divert water from main river and its 

tributaries above and below station. Large quantities of water are taken 

out of underground storage by flowing wells and pumping plants.

REGULATION. Storage has been developed at Bear Valley Reservoir in upper 

Santa Ana Basin and Hemet Reservoir in San Jacinto Basin. Lake Elsinore 

receives the run-off from San Jacinto Basin and discharges into Temescal 

Creek only during seasons of very high run-off. (See Lake Elsinore at 

Elsinore, p. 66.)

ACCURACY. Stage-discharge relation continually changing. Standard rating 

curves not well defined. Water-stage recorder gave good record except 

for a few days when there was no communication between gage well and 

stream and December 27 to January 7 and September 13-22, when clock 

was not running. Daily discharge ascertained by shifting-control method 

or was estimated or interpolated during periods of no gage height. Records 

fair.

SANTA ANA RIVER BASIN 37

SOUTHERN CALIFORNIA EDISON CO.'S CANAL AND GREENSPOT PIPE LINE NEAB MENTONE,

CALIF.

LOCATION. At Southern California Edison Co.'s Mentone power plant at mouth

of canyon, 2^ miles below intake on Santa Ana River1 and 3 miles northeast

of Mentone, San Bernardino County. 

RECOKDS AVAILABLE. 1896 to September 30, 1923. 

DISCHAHGE. Canal discharge computed from records showing kilowatt output

of power plant. Pipe-line discharge computed from weir record at forebay. 

EXTBEMES OF DISCHAKGE. 1896-1923: Maximum mean daily canal discharge;

recorded^ 97 second-feet March 16, 1905; no flow during short periods nearly

every year. 

DIVEKSIONS. Water diverted from the forebay by the Greenspot pipe line must

be added to give total flow of canal above forebay. From 1903 to 1911 pipe

line diverted from canal above forebay but no discharge was reported. The

present pipe line was put in operation September 7, 1911. 

ACCTTBACY. The record for power canal is computed on the assumption that

1 second-foot develops 18.9 kilowatts. The weir recorder the pipe line is

considered good.' 

COOPEEATION. Record furnished by Southern California Edison Co. through

H. W. Dennis, chief civil engineer.

The intake of this canal is at Southern California Edison Cbi's power plant 

No. 2, 2% miles above Mentone plant. All the water, except that taken by the 

Greenspot pipe line, is first used for development of power. After it leaves the 

Mentone power house it is carried across Santa Ana River in a flume and discharged into a lined canal from which it is distributed for irrigation. Before it 

enters the irrigation canal it has passed through three power plants.

Daily discharge, in second-feet, of Southern California Edison Co.'s canal near 

Mentone, Calif., for the year ending September 30, 1923

SANTA ANA ETVEB BASIN 39

MH1 CREEK NEAR CRAFTONVHIE, CALIF.

LOCATION. In NE. ^ sec. 13, T. 1 S., R. 2 W., at mouth of canyon, on Redlands-Bear Valley highway, 5^ miles northeast of Craftonville, San 

Bernardino County.

DRAINAGE ABBA. Not measured.

RECOBDS AVAILABLE. January 21, 1919, to September 30, 1923.

GAGE. Water-stage recorder on left bank just above Southern California 

Edison Co.'a concrete diversion dam. Datum lowered 1 foot November 

21, 1922.

DISCHARGE MEASUREMENTS. Made from highway bridge 75 feet below gage or 

by wading.

CHANNEL AND CONTROL. Bed consists of gravel and boulders; shifts during 

high stages. Control is concrete diversion dam but is not very satisfactory 

on account of the gravel which collects at dam.

EXTREMES OF DISCHARGE. Maximum stage during year, from water-stage 

recorder, 3.20 feet at 4 a. m. December 13 (discharge not determined); all 

water diverted into Mill Creek power canal No. 1 October 1 to December 10, 

December 20 to April 15, and May 28 to September 30, except September 2. 

1919-1923: Maximum stage recorded, 4.80 feet December 20, 1921 (discharge, about 896 second-feet); all water diverted into Mill Creek power 

canal No. 1 at various times.

DIVERSIONS. Mill Creek power canal No. 1 heads at the diversion dam at the 

station. Power canal No. 2 heads about 3 miles farther up the canyon and 

canal No. 3 about 3 miles above the headworks of canal No. 2. Canals Nos. 

2 and 3 lead to power plants Nos. 2 and 3 which are located in a combined 

power house near the intake of canal No. 1. The tailrace of the combined 

power house discharges into canal No. 1 and the water is used in power plant 

No. 1. Water is diverted from Mill Creek by canal No. 1 only when the water 

discharged from the combined power house is insufficient to operate power 

plant No. 1 to capacity. Ordinarily when canal No. 1 can not take all the 

flow in the creek it is not operated as the diversions by canals Nos. 2 and 3 

furnished sufficient water for plant No. 1. From May 25 to September 28, 

1922, and April 16 to May 27, 1923, water was diverted by canal No. 1 in 

addition to some being wasted down the creek. This diversion is included 

in the flow of the creek.

ACCURACY. Stage-discharge relation did not change during the year. Rating 

curve fairly well defined by four discharge measurements. Water-stage 

recorder record good. Daily discharge ascertained by applying mean daily 

gage height to rating table. Discharge December 15-19 estimated as water 

was wasted back to creek from No. 1 canal. May 27 and September 2 estimated. Combined daily discharge of creek and canals is the sum of flow in 

creek, power canals Nos. 2 and 3, and canal No. 1, except for the period April 

16 to May 26, when flow in creek included flow in canal No. 1. Records good.

COOPERATION. Water-stage recorder attended by employee of Southern California Edison Co.

50 SURFACE WATER SUPPLY, 1923, PAST XI

STRAWBEERY CREEK NEAR ARROWHEAD SPRINGS, CALIF.

LOCATION. At the Del Rosa Water Co.'s diversion dam in SE. M sec- 11, T. 1 

N., R. 4 W., half a mile south of Arrowhead Springs, San Bernardino County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. I ecember 27, 1919, to September 30, 1923.

GAGE. Water-stage recorder in concrete well and house on right bank 100 feet 

above diversion dam.

DISCHARGE MEASUREMENTS. Made from footbridge 200 feet above gage or by 

wading.

CHANNEL AND CONTROL. Bed consists of large boulders. Control is of boulders 

and concrete, 15 feet below gage.

EXTREMES OF DISCHARGE. Maximum stage during year, estimated by comparison with Waterman Creek, 2.95 feet at 6 a. m. December 14 (discharge, 

121 second-feet); minimum stage, from water-stage recorder, 0.43 foot 

from 4 to 8 p. m. September 2 (discharge, 0.9 second-foot).

1920-1923: Maximum stage, from water-stage recorder, 3.87 feet at 5 

a. m. January 2, 1922 (discharge, 408 second-feet); minimum stage, from 

water-stage recorder, 0.62 foot at 5 p. m. September 26, 1921 (discharge, 

0.7 second-foot).

DIVERSIONS. Arrowhead Hotel Co. diverts water through a 3-inch pipe line, 

for domestic use, from East Twin Creek 1 mile above gage.

REGULATION. Slight regulation at low water from diversion of Arrowhead 

Hotel Co.

ACCURACY. Stage-discharge relation changed when control was blocked with 

de'bris from a forest fire November 9 and again when it was cleared June 19. 

Discharge measurements during this period show practically continuous 

change in stage-discharge relation. Standard rating curves well defined. 

Water-stage recorder record of no value November 10-14, November 21 

to December 5, December 22 to January 13, as intake was clogged. Daily 

discharge ascertained by applying mean daily gage height to rating table 

October 1 to November 8 and by shifting-control method November 9 to 

September 30. Discharge interpolated for days on which intake was 

clogged. Records good.

ELSINORE LAKE AT ELSINORE, CALIF.

LOCATION. On northeast shore near outlet at Elsinore, Riverside County.

RECORDS AVAILABLE. December 1, 1915, to September 30, 1923.

GAGE. Vertical staff on northeast shore near outlet; read by W. L. Wilhite. 

Several gages at slightly different datums have been used but all have been 

referred to mean sea level. The location has been changed frequently in 

order to accommodate the rising or receding of the lake. The published 

elevations may be reduced to mean sea level by adding 1,200 feet.

Elsinore Lake overflows only during and after years of heavy rainfall. Temescal Creek is the high-water outlet for the lake. The heavy rains during the winte r
SANTA ANA RIVER BASIN 67

and spring of 1916 filled the lake and there was flow in Temescal Creek during 

1916 and until July, 1917. The surface of the lake has been below the outlet, 

since the later date. A history of the lake is published in United States Gecn 

logical Survey Water-Supply Papers 426, 429, and 441.

SAN GABRIEL RIVER BASIN

SAN GABRIEL RIVER NEAR AZUSA, CALIF.

LOCATION. In NW. % sec. 23, T. 1 N., R. 10 W., near road crossing at mouth 

of canyon, half a mile above Southern California Edison Co.'s power house, 

and 2 miles north of Azusa, Los Angeles County.

DRAINAGE AREA. 214 square miles (revised measurement).

RECORDS AVAILABLE. 1894 to September 30, 1923.

GAGE. A new water-stage recorder well was completed on November 18, 1922. 

For description of gages used in previous years see water-supply papers of 

those years.

DISCHARGE MEASUREMENTS. Made from cable 1,000 feet above ford or by 

wading near gage.

CHANNEL AND CONTROL. Gravel and boulders; shifts during high water.

EXTREMES OF DISCHARGE. Maximum stage during year, from floodmarks, 5.46 

feet morning of December 13 (discharge, 3,670 second-feet); no flow October 1 

to November 8> November 19 to December 2, and June 1 to September 30. 

1894-1923: Maximum stage recorded, 12.0 feet January 18, 1916 (discharge, 40,000 second-feet); stream dry for several months each year.

DIVERSIONS. The power canal of the Southern California Edison Co. heads 

about 5 miles above the station. (For daily discharge of this canal see p. 78.)

REGULATION. None.

ACCURACY. Stage-discharge relation changed frequently during year. Rating 

curves fairly well defined. Record from water-stage recorder good December 

3 to May 23. Daily discharge ascertained by applying mean daily gage 

height to rating tables except November 9-18, March 29 to April 6, and 

May 24-31, for which it was estimated from discharge measurements, and 

December 19 and May 16, for which it was interpolated. Records good.

SAWPIT CREEK NEAR MONROVIA, CALIF.

LOCATION. In SE. M NW. M sec. 13, T. 1 N., R. 11 W., at highway bridge just 

below junction of two main branches, 2 miles north of Monrovia, Los Angeles 

County.

DRAINAGE AREA. 5.3 square miles (measured on topographic map.)

RECORDS AVAILABLE. November 8, 1916, to September 30, 1923.

GAGE. Water-stage recorder in concrete well and shelter, on left bank at east 

end of highway bridge.

DISCHARGE MEASUREMENTS. Made from bridge or by wading near gage.

CHANNEL AND CONTROL. Bed consists of coarse gravel and boulders; apparently 

permanent. Channel is straight for 25 feet above gage and curved below; 

banks are high. A concrete and boulder dam was built across channel just 

below gage for an artificial control. Stage-discharge relation was changed 

by a rock slide at control on December 25, 1921.

EXTREMES OF DISCHARGE. Maximum stage during year, from water-stage 

recorder, 2.73 feet at 2 a. m. December 13 (discharge, 47 second-feet); stream 

dry at gage for several months. »

1916-1923: Maximum stage recorded, 2.65 feet March 10, 1918 (discharge, 

256 second-feet); a stage of 4.35 feet with a discharge of 178 second-feet 

occurred February 9, 1922; stream dry several months each year.

DIVERSIONS. Part of the water supply for Monrovia is obtained from the two 

branches of Sawpit Creek above gage. See record for Monrovia pipe line 

(P- 84).

REGULATION. None.

ACCURACY. Stage-discharge relation changed during high water of December 

13. Rating curves fairly well defined. No record from water-stage recorder 

March 8 to April 9. Daily discharge ascertained by applying mean 

daily gage height to rating table, except December 6, January 29, March 

8 to April 9, for which discharge was estimated by comparison with Fish 

Creek. Records fair.

COOPERATION. City of Monrovia furnished observer for water-stage recorder.

86 SURFACE WATER SUPPLY, 1923, PART XI

SAN DIMAS CREEK NEAR SAN DIMAS, CALIF.

LOCATION. In SW. ^i NE. ^ sec. 25, T. 1 N., R. 9 W., at mouth of San Dimas 

Canyon, 3 miles northeast of San Dimas, Los Angeles County.

DRAINAGE AREA. 18.3 square miles (measured on topographic map).

RECORDS AVAILABLE. December 3, 1916, to September 30, 1923. (Discharge 

measurements only, April 14 to September 4, 1916.)

GAGE. Water-stage recorder, in concrete well and house, on left bank.

DISCHARGE MEASUREMENTS. Made from cable about 50 feet above gage or by 

wading.

CHANNEL AND CONTROL. Bed consists of sand, gravel, and boulders; shifting. 

Control is low concrete dam built across channel just below gage well. This 

dam was raised about 2 feet January 18-23, 1918. During 1921 a wooden 

dam about 2J^ feet high was built on the control. There is a notch in it, 

in which are placed one or more planks to raise water so it can be diverted 

through a 12-inch pipe. This dam is removed at times. Gravel fills in above 

and below dam affecting stage-discharge relation. Left bank is steep and not 

subject to overflow; right bank is brushy and is overflowed during highstages.

EXTREMES OP DISCHARGE. Maximum stage during year, from flood marks. 

6.54 feet at 11 p. m. December 12 (discharge, 49 second-feet); practically 

dry afternoon of September 14.

1916-1923: Maximum stage, from water-stage recorder, 5.95 feet at 2 

p. m. February 9, 1912 (discharge, about 1,140 second-feet); stream dry 

during a part of October and November, 1916, September, 1919, August to 

December, 1921, and part of September 14, 1923.

DIVEKSIONS. The San Dimas Water Co. diverts water for irrigation through a. 

pipe line at the dam.

REGULATION. Unknown amount of storage developed above the gage.

ACCURACY. Stage-discharge relation depends on presence of temporary wooden 

diversion dam on top of concrete control and a plank in the control notch. 

Channel above dam also shifts causing changes in stage-discharge relation. 

Rating curves for each condition fairly well defined. Water-stage recorder 

record good, except for parts of December 12 and 13. Daily discharge ascertained by applying mean daily gage height to rating tables, except for several 

short periods, for which it was interpolated or estimated. Records fair.

HAINES CREEK NEAR TUJUNGA, CARF.

LOCATION. In NE. J^ NE. % sec. 18, T. 2 N., E. 13 W., 800 feet above mouth of

canyon and 1J^ miles northeast of Tujunga, Los Angeles County. 

DBAINAGE ABBA. 1.2 square miles (measured on topographic map). 

RECOBDS AVAILABLE. February 7, 1917, to September 30, 1923. 

GAGE. Water-stage recorder in concrete well and house, on right bank.
LOS ANGELES EIVER BASIN 93

DISCHARGE MEASUREMENTS. Made by wading near gage, or by volumetric method 

when discharge is very small. A gaging bridge, for use during high water, 

is located just above gage.

CHANNEL AND CONTBOL. Bed consists of boulders and gravel overlying solid 

rock, permanent; banks are high and fairly clean. A concrete dam, having 

a maximum height of about 5 feet above bedrock, was built across the channel 

at downstream face of gage well. A 12-foot concrete wing wall was constructed at left end of dam. Crest of dam has a trapezoidal notch 6 inches 

wide on bottom and 1 foot deep, which makes control more sensitive for low 

stages. Zero flow, gage height 0.23 foot.

ExTBEMEs OF DiscHABGE. Maximum stage during year, from water-stage 

recorder, 0.70 foot at 11 p. m. December 12 (discharge, 0.85 second-foot); 

minimum stage, 0.26 foot September 4-20 (discharge, 0.02 second-foot).

1917-1923: Maximum stage recorded, 1.74 feet January 2, 1922 (discharge, 15 second-feet); stream dry July 18 to August 1, 1921.

INVERSIONS. About a mile above the station a tunnel has been driven into ]bhe 

stream bed and a 4-inch pipe carries the water past the gage. This water is 

used for domestic supply at Tujunga. A similar tunnel, a short distance 

below the station, obtains a small supply during the greater part of the year.

REGULATION. A large number of small check dams, constructed of brush and 

boulders, have been built across the stream channel in the upper part of the 

drainage basin. ' '

ACCURACY. Stage-discharge relation changed December 14. Rating curves 

well defined. Operation of water-stage recorder satisfactory. Daily discharge ascertained by applying mean daily gage height to rating table. 

Records good.

RECORDS AVAILABLE. April 15, 1916, to September 30, 1923.

GAGE. Water-stage recorder on left bank about 150 feet below Scherer's cabin.

DISCHARGE MEASUREMENTS. Made from wooden bridge near gage or by wading.

CHANNEL AND CONTROL. Bed consists of gravel and boulders; one channel at 

all stages; straight for 75 feet above control. Right bank is rock cliff; left 

bank is stone wall 5 feet high which is probably above maximum stage. 

Control is small concrete dam, with triangular notch at left end, just below 

gage. Control is not permanent for high stages on account of varying 

amounts of gravel deposited in pool just above dam. Zero flow, gage 

height 0.70 foot; top of dam, gage height 1.50 feet.

EXTREMES OF DISCHARGE. Maximum stage during year, from water-stage 

recorder, 2.25 feet at 1 a. m. December 13 (discharge, 36 second-feet); minimum stage, from water-stage recorder, 0.87 foot at 7 p. m. September 20 

(discharge, less than 0.05 second-foot); stream probably dry part of each 

day about September 9 and 10 during period of missing gage-height record. 

1916-1923: Maximum stage recorded 2.55 feet at 8 p. m. March 13, 1921 

(discharge, 98 second-feet); a stage of 2.74 feet and a discharge of 93 secondfeet occurred February 9, 1922; stream dry during part of each day September 16 and 17, 1919.

DIVERSIONS. None above.

REGULATION. None.

AcctiRACY.-^Stage-discharge relation did not change during the year. Rating 

curve well defined up to 25 second-feet and extended above. Good gageheight record.from water-stage recorder except August 9 to September 16. 

Daily discharge ascertained by applying mean daily gage height to rating 

table, except November 9 and December 6 and 12 for which bi-hourly discharge was averaged; mean monthly flow for August and September estimated by comparison with records for adjacent streams. Records good.

curves fairly well defined. Staff gage read to tenths once daily except 

during changing stage when it is read oftener and the peak stage noted. 

Daily discharge ascertained by applying daily gage height to rating table, 

except December 10-13, January 22-25, and April 2-7 for which it was 

determined by plotting discharge hydrographs using all available gage 

readings and by comparison with records of flow at Edenvale and Madrono. 

Discharge interpolated on days for which gage was not read. Records fair.

DRAINAGE AREA. 620 square miles (mesaured by Spring Valley Water Co.).

RECORDS AVAILABLE. October 4, 1900, to September 30, 1923.

GAGE. Water-stage recorder on upstream face of dam on left bank. Previous 

to 1914 a,staff gage on upstream side of dam on right bank was used.

DISCHARGE MEASUREMENTS. Made from suspension footbridge about 400 feet 

above dam. Heavy weights and stayline are used for high-water measurements to insure correct position of current meter.

CHANNEL AND CONTROL. The concrete dam acts as a control for the station. 

Bed above and below dam consists of gravel .and boulders; shifts during 

high water.

EXTREMES or DISCHARGE. 1901-1923: Maximum mean daily discharge, 14,700 

second-feet March 7, 1911; minimum, no flow for part of nearly every year.

DIVERSIONS. See Spring Valley Water Co.'s aqueduct near Sunol, page 121,

REGULATION. Spring Valley Water Co. has under construction a large reservoir on Calaveras Creek. Water was released from Calaveras Reservoir 

after periods of natural flow.

ACCURACY. The dam has been rated in accordance with the cooperative agreement between the Spring Valley Water Co. and the city of San Francisco. 

Current-meter measurements have been obtained by both parties and a 

rating curve developed which has been accepted by both.
118

COOPERATION. Records showing millions of gallons per day furnished by Spring: 

Valley Water Co. through G. A. Elliott, chief engineer. Daily discharge 

converted into second-feet and monthly discharge computed by engineers* 

of United States Geological Survey.

DIVERSIONS. Practically all the low-water flow is diverted just below gage into

Kern River No. 3 canal. 

REGULATION. None. 

ACCURACY. Stage-discharge relation fairly permanent. Rating curve fairly well

defined. Gage-height record good except for the period July 8-25 when the

weir was sWglitly undermined apti 'April 3-13 when charts were lost. Daily

discharge ascertained by applying mean daily gage height to rating table

except April 3-13 and July 8-25, for which they were estimated. Discharge

interpolated March 11-12 and May 24. Records good. 

COOPERATION. Gage-height record and results of discharge measurements

furnished by Southern California Edison Co., through H. W. Dennis, chief

civil engineer.

SAN JOAQUIN RIVER NEAR NEWMAN, CALIF.

LOCATION. In SW. M sec. 3, T. 7 S., R. 9 E., at drawbridge on Hill's ferry road,

300 feet below mouth of Merced River and 3J£ miles northeast of Newman,

Stanislaus County. 

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 29, 1912, to September 30, 1923. 

GAGE. Vertical staff fastened to upstream side of downstream support of draw

span, 60 feet below bridge, in middle of stream. Gage read by Rasmus

Lorensen.

DISCHARGE MEASUREMENTS. Made from bridge or by wading. 

CHANNEL AND CONTROL. Sand and small gravel; shifts during high water.

Banks subject to overflow. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 13.9 feet at

7 a. m. and 5 p. m. May 26 and 7 a. m. May 27 (discharge, 12,100 secondfeet); minimum stage recorded, 2.2 feet September 10 and 11 (discharge,

222 second-feet); minimum discharge, 90 second-feet on October 17 and 18. 

1912-1923: Maximum stage recorded, 18.0 feet at 9 a. m. January 27,

1914 (discharge, 20,700 second-feet); minimum stage recorded, 1.0 foot

October 5 and 8-18, 1913 (discharge, 50 second-feet). 

DIVERSIONS. Practically entire low-water flow of main river and tributaries is

diverted for irrigation, hence the low-water records show mainly the amount

of return water. 

REGULATION. Storage is developed for power at Huntington Lake on Big Creek,

at Crane Valley Reservoir on North Fork Creek, and a small amount on

Stevenson Creek at Shaver. 

ACCURACY. Stage-discharge relation changed frequently during the year.

Rating curves well defined. Staff gage read to hundredths twice daily.

Daily discharge ascertained by applying mean daily gage height to rating

table or by shifting-control method. Records good.

LOCATION. In sec. 28, T. 8 S., R. 25 E., one-fourth mile above mouth and half a

mile southeast of Big Creek post office, Fresno County. Elevation, 5,000

feet. 

DRAINAGE AREA. 27 square miles (measured on topographic map by Pacific

Light & Power Co.). 

RECORDS AVAILABLE. January 1, 1910, to September 30, 1915, and January 26,

1922, to September 30, 1923. 

GAGE. Water-stage recorder in wooden well and house at right side on weir pool.

about 50 feet above highway bridge. Zero of gage is at elevation of weir

crest. 

DISCHARGE MEASUREMENTS. Made from footbridge about 15 feet above weir or

by wading. 

CHANNEL AND CONTROL. Sharp-edged 38-foot rectangular weir with partial end

contractions, at lower end of natural pool in solid rock. Considerable

velocity of approach at high stages. 

EXTREMES OP DISCHARGE. Maximum stage during year, from water-stage

recorder, 2.48 feet at 6 p. m. May 15 (discharge, 690 second-feet); minimum

stage, from water-stage recorder, 0.04 foot October 10-26 and September 10-

12 (discharge, 2.2 second-feet).

1910-1915: Extremes of discharge occurring in 1910, 1911, and 1913 were

based on computations from formula, without discharge measurements, and

are not considered as reliable as later records.

1922-1923: Maximum stage, from water-stage recorder, 3.53 feet at

6 p. m. June 1, 1922 (discharge, 1,110 second-feet); minimum stage, from

water-stage recorder, 0.04 foot October 10-26 and September 10-12, 1923

(discharge, 2.2 second-feet). 

ICE. Water-stage recorder float operated in oil container. Ice formed on weir

crest occasionally and caused backwater, for which allowance was made

before application of open-water rating. 

DIVERSIONS. Southern California Edison Co. diverts water above gage for

power house No. 1 hydraulic valves, and for cooling transformers; estimated

maximum diversion 0.5 second-foot. 

REGULATION. None. 

ACCURACY. Stage-discharge relation permanent. Rating curve well defined.

Gage heights slightly affected by ice during winter and proper corrections

made. Water-stage recorder gave excellent gage-height record except

December 23-31. Daily discharge ascertained by applying mean daily gage

height to rating table October 1 to April 4 and June 2 to Sepember 30; by

use of discharge integrator April 5 to June 1. Records excellent. During

the year 42 discharge measurements were made at the station. 

COOPERATION. Gage-height record and results of discharge measurements

furnished by Southern California Edison Co. through H. W. Dennis, chief

civil engineer.

STEVENSON CREEK AT SHAVER, CALIF.

LOCATION. In sec. 13, T. 9 S., R. 24 E., three-fourths mile west of Shaver, Fresno

County. Elevation about 5,000 feet.

DRAINAGE ABE A. 30.2 square miles (measured on topographic map). 

RECORDS AVAILABLE. October 1, 1916, to September 30, 1920, and April 9, 1922,

to September 30, 1923. 

GAGE. Water-stage recorder in wooden well and house on right bank about 20

feet above compound weir. Zero of gage set at elevation of crest of lower

weir.

57284 28 13
186 SURFACE WATER SUPPLY, 1923, PAST XI

DISCHARGE MEASUREMENTS. Made from cable one-fourth mile above gage or

by wading. 

CHANNEL AND CONTROL. Bed composed of boulders and bedrock. Control is

a compound weir consisting of a 64-foot rectangular sharp-crested weir with

incomplete end contractions, and an 8-foot rectangular sharp-crested weir

1 foot deep, in middle of the larger weir. Leakage is small. Velocity of

approach is considerable at high stages. 

EXTREMES OF DISCHARGE. Maximum stage during year, from water-stage

recorder, 1.83 feet at 3 a. m. May 8 (discharge, 209 second-feet); minimum

stage, from water-stage recorder, 0.11 foot at noon January 10 (discharge,

0.6 second-foot).

1916-1920; 1922-1923: Maximum mean daily discharge, 712 second-feet

on April 7, 1920, minimum stage, 0.12 foot August 27 to September 8, 1922

(discharge, 0.7 second-foot).

ICE. Stage-discharge relation slightly affected by ice, January 29 to February 2. 

DIVERSIONS. Southern California Edison Co.'s flume at Shaver diverts water at

Shaver Lake Dam and from Camp 22 Creek, a tributary of Stevenson Creek.

This water is used at power houses 2 and 8, then spills into Big Creek near

mouth. See page 188 for daily discharge of the flume. 

REGULATION. During dry season flow is regulated at Shaver Lake Dam. There

was 3,191 acre-feet of water in Shaver Lake on September 30,1922, and 3,579

acre-feet on September 30, 1923. 

ACCURACY. Stage-discharge relation did not change during year. Rating curve

fairly well defined. Water-stage recorder gave excellent gage-height record.

Daily discharge ascertained by applying mean daily gage height to rating

table, except April 10, 11, May 6, and 8, which were subdivided. Discharge

January 29 to February 2 estimated. Records fair. 

COOPERATION. Gage-height record furnished by Southern California Edison Co.

through H. W. Dennis, chief civil engineer.

No discharge measurements were made during the year.

Daily discharge, in second-feet, of Stevenson Creek at Shaver, Calif., for the year 

ending September 30, 1928

feet.

RECORDS AVAILABLE. February 16, 1922, to September 30, 1923.

GAGE. Water-stage recorder in wooden well and house.

DISCHARGE MEASUREMENTS. Made from plank about 200 feet above gage,

CHANNEL AND CONTROL. Timber flume 6.85 feet wide and 6 feet deep lined with 

tar paper held in place with fine mesh galvanized wire and battens. Control 

is indefinite.

EXTREMES OF DISCHARGE. Maximum stage during year, from water-stage 

recorder, 4.72 feet at 1 p. m. April 11 (discharge, 368 second-feet); minimum stage, flume dry at various times.

1922-1923: Maximum stage, from water-stage recorder, 4.72 feet at 

1 p. m. April 11, 1923 (discharge, 368 second-feet); flume dry at times 

during each year.

ICE. Stage-discharge relation not seriously affected by ice.

ACCURACY. Stage-discharge relation changed on account of impermanence of 

paper lining of flume. Rating curves fairly well defined. Good gageheight record from water-stage recorder with only one missing period May 30 

to June 2. Daily discharge ascertained by use of discharge integrator 

April 1 to July 21; for the remainder of the year, by applying mean daily 

gage height to rating table, or on days of considerable fluctuation by computing and summing discharge for subdivided days. Southern California 

Edison Co. furnished estimated discharge for period May 30 to June 2. 

Records fair. During the year 8 discharge measurements were made at the 

station.

OOPERATION. Gage-height record and results of discharge measurements 

furnished by Southern California Edison Co. through H. W. Dennis, chief

MERGED RIVER AT EXCHEQUER, CAIIF.

LOCATION. In SW. }& NE. }& sec. 13, T. 4 S., R. 15 E., just above remains 

of an old dam at Exchequer, Mariposa County, above mouth of Cotton 

Creek, and 8 miles upstream from Merced Falls. A new station 1 mile 

downstream and about on section line between sees. 14 and 23, T. 4 S., R. 

15 E., was put into operation on October 25, 1922.

DRAINAGE AREA. 1,020 square miles (measured on topographic maps) at old 

site. Not measured at new site.

RECORDS AVAILABLE. November 28, 1915, to September 30, 1923.

GAGE. Water-stage recorder on right bank 250 feet above the dam at old site. 

Water-stage recorder on right bank at new site.

DISCHARGE MEASUREMENTS. Made from cable one-half mile above gage or by 

wading just below cable or on top of dam at old site. From cable 1 mile 

below gage at new site or by wading.

CHANNEL AND CONTROL. Bed consists of boulders, gravel, and solid rock. 

Control at old site is old concrete dam. Banks high, clean, not subject to 

overflow. Part of dam was blasted February 1, 1918, to make a fishway. 

At new site channel is solid rock overlain with gravel. Control will probably 

be permanent.
200 SITBFAOE WATER SUPPLY, 1923, PABT XI

EXTREMES OF DISCHARGE. Maximum stage during year from water-stage 

recorder, 10.50 feet at 10.30 a. m. April 6 (discharge, 11,500 second-feet); 

minimum stage from water-stage recorder, 0.13 foot at 2 p. m. September 

14 (discharge, 16 second-feet).

1915-1923: Maximum stage recorded, 20.0 feet at 4 p. m. January 17, 

1916 (discharge, determined from extension of rating curve, about 22,000 

second-feet); minimum stage recorded, 4.0 feet in August 1921, and September, 1919 and 1921 (discharge, 14 second-feet).

DIVERSIONS. None.

REGULATION. Several small power plants above have little or no storage. The 

effect of their operation is slight except during low water, when they alternate with the plant at Mereed Falls in storing water and developing power 

twice daily.

ACCURACY. Stage-discharge relation at new site practically permanent. Rating 

curve at old site well defined; curve at new site well defined between 20ft 

and 7,000 second-feet and extended above and below. Recorder record 

excellent. Daily discharge ascertained by applying mean daily gage height 

to rating table October 25, November 19 to December 15, January 23-26, 

and August 1 to September 30 and by means of a discharge integrator at 

other times. Records excellent.

COOPERATION. Gage-height record and results of discharge measurements

recorder, 12.30 feet at 3 a. m. June 10 (discharge, 8,350 seconds-feet); minimum stage, from water-stage recorder, 0.60 foot at 10 a. m. May 15 (discharge, 2.0 second-feet. Plow completely regulated by Hetch Hetchy 

Reservoir).

1915-1923: Maximum stage, from water-stage recorder, 13.4 feet at 3 a. m. 

May.29, 1919 (discharge, 11,400 second-feet); minimum stage, from waterstage recorder, 0.60 foot at 10 a. m. May 15, 1923 (discharge, 2.0 second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. None.

REGULATION. Regulated by gates in O'Shaughnessy Dam at Hetch Hetchy 

Reservoir since completion of dam in 1923. There was 151,500 acre-feet of 

water in Hetch Hetchy Reservoir September 30, 1923.

ACCURACY. Stage-discharge relation permanent. Rating curve very well 

defined. Water-stage recorder record excellent except for periods October 

4-8 and January 16 to February 13 when the clock was stopped. Daily 

discharge ascertained by applying mean daily gage height to rating table 

except May 8, 25, July 7, and August 18 and 19, for which hourly discharge 

was averaged. Discharge for periods of no gage-height record were estimated 

from records of Tuolumne River near Buck Meadows, Cherry Creek, and 

Eleanor Creek. Records excellent.

TUOLUMNE RIVES ABOVE IA GRANGE DAM, NEAR IA GRANGE, CAIIF.

LOCATION. In NE. % sec. 3, T. 3 S., R. 14 E., half a mile below Don Pedro 

Dam, 3J^ miles above La Grange Dam and 5 miles above La Grange, 

Stanislaus County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. March 19, 1915, to September 30, 1923, also 1895 to 

1917 at La Grange Dam.

GAGE. Water-stage recorder on left bank half a mile below Don Pedro Dam.

DISCHARGE MEASTTREMENTS. Made from cable 80 feet below gage or by wading.

CHANNEL AND CONTROL. Bed consists of solid rock and boulders. Banks 

are high, one channel at all stages. Control is solid rock dike which extends 

entirely across the stream and over which at low water there is a drop of 

about 5 feet. Point of zero flow, gage height 0.06 foot.

EXTREMES OF DISCHARGE. Maximum stage during year from water-stage 

recorder, 16.4 feet at 10.30 a. m. June 25 (discharge, 12,900 second-feet); 

minimum stage, from water-stage recorder, 0.54 foot November 26 to 

December 1 (discharge, 1.4 second-feet; flow completely regulated by gates 

in Don Pedro Dam).

1915-1923: Maximum stage recorded, 27.58 feet at 5.15 p. m. February 

21, 1917 (discharge, 36,500 second-feet); minimum stage recorded, 0.54 

foot November 26 to December 1, 1922 (discharge, 1.4 second-feet).

DIVERSIONS. Sierra & San Francisco Power Co.'s canal diverts at the Don 

Pedro Dam since the dam was completed. Prior to that date it diverted at 

Indian Bar 73^ miles upstream. Water was used for power and returned to 

river half a mile above bridge at La Grange until May 22, 1923; after that 

date the water was used to supply the town of La Grange. There is also a 

diversion from South Fork of Tuolumne River at Harden ranch for irrigation in vicinity of Groveland.

REGULATION. Completely regulated by gates in Don Pedro Dam. The dam 

was completed about January 1, 1923. Water was stored at times during 

November and December, 1922. The reservoir was filled for the first time 

about June 25, 1923. There was 183,000 acre-feet of water in Don Pedro 

Reservoir September 30, 1923. Water is also stored in Hetch Hetchy 

Reservoir and Lake Eleanor. See pages 207 and 217.

ACCURACY. Stage-discharge relation permanent. Rating curve very well 

denned. Water-stage recorder record excellent except for period January 

14-21 when clock was stopped. Daily discharge ascertained by applying 

mean daily gage height to rating table except November 16, 23, 24, December 

2, 26, January 1, February 1, 3, 8, 21, 23, 28, and March 1 for which hourly 

discharge was averaged. Discharge for period January 14-21 estimatedRecords excellent except for estimated period for which they are fair.

SIERRA & SAN FRANCISCO POWER CO.'S CANAL NEAR LA GRANGE, CAUF.

LOCATION. In SW. M sec. 16, T. 3 S., R. 14 E., at short flume opposite La 

Grange Dam, just above waste gate, three-fourths mile above power house, 

1% miles northeast of La Grange, Stanislaus County, and 4 miles below 

intake at Don Pedro Dam on Tuolumne River.

RECORDS AVAILABLE. 1908 to September 30, 1923 (not complete).

GAGE. Enameled vertical staff on right side of flume near upper end; read by 

H. T. Sackett.

DISCHARGE MEASUREMENTS. Made in flume just below gage.

CHANNEL AND CONTROL. Rectangular ditch excavated mostly in shale rock.

EXTREMES OF DISCHARGE. 1908-1923: Maximum discharge recorded, 72 secondfeet November 28, 1921.

ACCURACY. Stage-discharge relation changed when canal was empty December 

14-30. Rating curves well defined. Gage read to hundredths once daily. 

Daily discharge ascertained by applying gage height to rating table. Records 

good.

COOPERATION. Gage-height record furnished -by Turlock irrigation district, 

through R. V. Meikle, chief engineer.

The Sierra & San Francisco Power Co.'s canal takes water from the south side 

of Tuolumne River at Don Pedro Dam. It originally diverted at Indian Bar, 

in SW. }£ sec. 6, T. 2 S., R. 15 E., 13 miles above the town of La Grange. This 

canal was built in the early days to supply water for hydraulic mining in the 

vicinity of La Grange, and is now locally known as the "La Grange mining 

ditch." Having been thoroughly repaired, it was used as a supply canal for the 

hydroelectric plant which was installed in 1907 on the left bank of the river about 

half a mile above La Grange and below La Grange Dam. Water diverted by 

canal was returned to river at power house. May 23, 1923, the power plant was 

discontinued and the record now shows the amount of water diverted to supply 

the town of La Grange.

diverted for power development on Middle Fork at Sand Bar Flat near Avery 

is returned to river above this station.

REGULATION. Flow is partly regulated by storage in the drainage basins of the 

Middle, North, and South Forks.

ACCURACY. Stage-discharge relation changed from that of last year. Rating 

curve well defined below 6,000 second-feet and extended above. No record 

owing to trouble with water-stage recorder, October 16-21, November 25-27, 

December 15-17, 23, 25-30, January 9-14, January 20 to February 9, March 

2-3, 25-26, and April 9-21. Daily discharge ascertained by applying mean

SACRAMENTO RIVER NEAR RED BLUFF, CALIF.

LOCATION. In lot 4, sec. 34, T. 28 N., R. 3 W., at lower end of Iron Canyon, 4 

miles northeast of Red Bluff, Tehama County. Paines Creek enters 3 miles 

above and Antelope Creek 7 miles below station.

DRAINAGE AREA. 9,300 square miles, not including drainage area of Goose 

Lake 1,090 square miles which belongs naturally in Pit River basin but 

has contributed no water except for a short time in 1869 and for more than 

two hours during a severe storm from the north in 1881, when the lake 

overflowed to North Fork of Pit River. Previously published figures of 

discharge in second-feet per square mile and run-off in depth in inches, 

based on drainage area including Goose Lake, should be used with caution 

because of the large noncontributing area.

RECORDS AVAILABLE. January 28, 1902, to September 30, 1923. In 1879 the 

State engineer and in 1893 and 1894 the commissioner of public works made 

measurements at this point. Prom April 30, 1895, to June 30, 1902, a gaging 

station was maintained at Jellys Ferry, 12 miles above Red Bluff.
SACKAMENTO BIVER BASIN 247

GAGE. Water-stage recorder in concrete well and shelter on left bank. Outside 

staff gage in same section as the well. Previous to January 1, 1920, a staff 

gage in seven sections about 50 feet below the well was used. Datum not 

changed.

DISCHARGE MEASUREMENTS. Made from cable at the gage.

CHANNEL AND CONTROL. Coarse gravel and small boulders; practically permanent.

EXTREMES OP DISCHARGE. Maximum stage during year, from water-stage 

recorder, 11.60 feet at noon December 28 (discharge, 47,500 second-feet); 

minimum stage, from water-stage recorder, 0.30 foot part of August 27-28 

(discharge, 3,150 second-feet).

1902-1923: Maximum stage recorded, 35.2 feet February 3, 1909 (discharge, 278,000 second-feet); minimum stage, from water-stage recorder 

0.30 foot at 2.45 p. m. August 18, 1920, and part of August 27-28, 1923 

(discharge, 3,150 second-feet).

DIVERSIONS. Anderson-Cottonwood Canal has diverted water from Sacramento 

River at Redding since 1918. A small amount of water is diverted from 

some of the minor tributaries for irrigation.

REGULATION. No storage of any importance has been developed in the drainage area above the station. A small diurnal fluctuation at low water is 

probably caused by operation of power plants of Pacific Gas & Electric 

Co., on Hat Creek and Pit River.

ACCURACY. Stage-discharge relation practically permanent. Rating curve 

well denned. Water-stage recorder operated satisfactorily throughout year. 

Daily discharge ascertained by applying mean daily gage height to rating 

table. Records excellent.

TUBA RIVER AT SMARTSVHIE, CALIF.

LOCATION. In SW. M SW. M sec. 22, T. 16 N., R. 6 E., at Narrows, 1 mile north 

of Smartsville, Yuba County, 1 mile below mouth of Deer Creek, 6K miles 

below mouth of South Fork, 7 miles above mouth of Dry Creek, and 18 miles 

above junction with Feather River.

DRAINAGE AKEA. 1,220 square miles.

RECORDS AVAILABLE. June 2, 1903, to September 30, 1923.

GAGE. Staff in three sections, bolted to solid rock on left bank; read by Joseph 

French. On account of the gradual erosion of the channel, gage datum was 

lowered 10 feet August 1, 1906. Before the change, first section was vertical 

and driven into gravel near left bank 50 feet below cable; second section 

was painted on rock ledge on left bank.
288 STJBFACE WATEB SUPPLY, 1923, PABT XI

DISCHARGE MEASUREMENTS. Made from cable at gage.

CHANNEL AND CONTBOL. Gravel and small boulders; shifts during high water. 

As the result of extensive hydraulic mining in the early days the channel 

has been filled with an enormous quantity of tailings. At the station the 

depth of mining debris is estimated to be more than 80 feet.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 13.5 feet at 

12.25 p. m. December 13 (discharge, 28,000 second-feet); minimum stage 

recorded, 1.42 feet at 4.25 p. m. October 1 (discharge, 224 second-feet).

1903-1923: Maximum stage recorded, 28.3 feet January 15, 1909 (discharge, 111,000 second-feet); minimum stage recorded, 2.32 feet August 25, 

September 8 and 11, 1920 (discharge, 106 second-feet).

DIVERSIONS. Water is diverted for power and irrigation above the station.

REGULATION. Several small glacial lakes near the headwaters of the South Fork 

of Yuba River are utilized as storage reservoirs. A part of this water is 

diverted into Bear River drainage basin.

ACCURACY. Stage-discharge relation changed at high water of December 13 

and April 6. Rating curves, fairly well defined, are parallel and show very 

slight change in control. Gage read to quarter-tenths once daily. Daily 

discharge ascertained by applying daily gage height to rating table. Records 

good.

of water in Echo Lake on September 30, 1923. 

ACCURACY. Stage-discharge relation may shift slightly as the flume is old.

Rating curve based on one discharge measurement and point of zero flow.

Daily discharge ascertained by applying daily gage height to rating curve.

Records fair.

Canal diverts water from Echo Lake in Truckee River basin into South 

Fork of American River basin.

MEDLEY LAKES OUTLET NEAR VADE, CALIF.

LOCATION. In SW. M sec. 29, T. 12 N., R. 17 E., half a mile below auxiliary 

dams, 1 mile below main dam of Western States Gas & Electric Co. at 

Medley Lakes, and 5 miles northwest of Phillips, Vade post office, Eldorado 

County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. September 11, 1922, to September 30, 1923 (except 

winter).

GAGE. Water-stage recorder in masonry well and shelter on left bank just below 

the third small lake from the main dam.

DISCHARGE MEASUREMENTS. Made from a foot log across stream just below 

gage.

CHANNEL AND CONTROL. Bed of stream is smooth. Banks are solid granite, 

steep, and will not be overflowed. Water surface smooth; velocity good. 

Control is solid rock; permanent.

EXTREMES OF DISCHARGE. Maximum stage during period, from water-stage 

recorder, 2.10 feet at 4 p. m. May 24 (discharge, 82 second-feet); minimum 

stage, from Water-stage recorder, 0.24 foot August 4-9 (discharge, 0.6 secondfoot).

ICE. Snow collects to a depth of 12 feet forming a bridge across stream. At 

times this settles or breaks causing backwater, and stage-discharge relation 

was thus affected May 7-23.

DIVERSIONS. None.

REGULATION. Partly regulated by gates in dam at Medley Lakes. There was 

760 acre-feet of water in Medley Lakes on September 30, 1923.

ACCURACY. Stage-discharge relation permanent. Rating curve well defined. 

Water-stage recorder record good. No record obtained during the winter 

as the station is inaccessible. Daily discharge ascertained by applying mean 

daily gage height to rating table except May 7-15, 17, 18, 22, and 23, for 

which it was estimated from discharge measurements owing to snow on the 

control. Discharge September 15-22 estimated. Records good.

of Whitehall, Eldorado County.

DRAINAGE AREA. 22.8 square miles (measured on topographic maps).

RECORDS AVAILABLE. October 1, 1922, to September 30, 1923.

GAGE. Vertical staff gage, enamel sections, attached to a pier of the trestle 

work of the Eldorado Canal flume: read by ditch walker.

DISCHARGE MEASUREMENTS. Made from a plank across creek at the gage.

CHANNEL AND CONTROL. Bed of stream is smooth solid granite. Banks are 

steep and are not overflowed. Water surface smooth and swift. Control, 

solid granite; permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 3.45 feet, 

April 6 (discharge, 312 second-feet); minimum discharge recorded, 0.4 

second-foot August 26-28, September 9-12, and 15-21.

DIVERSIONS. Western States Gas & Electric Co. diverts water about 600 feet 

above gage through a feeder flume to Eldorado Canal. Water was diverted

SOUTH EEL RIVER AT VAN ARSDAIE DAM, NEAR POTTER VALLEY, CALIF.

LOCATION. In NE. ^ SE. H sec. 30, T. 18 N., R. 11 W., at Van Arsdale Dam 

of Snow Mountain Water & Power Co., 5 miles north of Potter Valley, 

Mendocino County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. November 18, 1909, to September 30, 1923. (Monthly 

discharge only for 1909 to 1922.)

GAGE. Water-stage recorded in pipe well and wooden shelter on left bank of 

equalizing reservoir about 800 feet above Van Arsdale Dam.

DISCHARGE MEASUREMENTS. Measurements in 1919 were made from a supension 

bridge below dam. Wading measurements made about IK miles below dam.

CHANNEL AND CONTROL. Control is the Van Arsdale Dam. Average elevation 

of crest of dam is 0.07 foot gage datum. At low water, flashboards are placed 

on crest. Crest of flashboards is very uneven; average elevation in 1923 

was 4.22 feet. Length of crest about 280 feet. A sluicje gate in bottom of 

dam is opened only when stage is rising rapidly or when reservoir is emptied. 

Reservoir is an enlargement of the natural stream and is about 400 feet wide, 

a mile or more long, and is fairly well filled with sand and aquatic plants.

EXTREMES OF DISCHARGE.' Maximum stage during the year, from water-stage 

recorder, 5.43 feet with flashboards on dam and sluice gate open at 4 a. m. 

April 8 (discharge, 1,800 second-feet). Maximum discharge, including flow 

through Potter Valley power house, 2,050 second-feet. Minimum discharge, 

about 2 second-feet, wasted down South Eel River on days for which daily 

discharge is not given. Minimum daily discharge, including flow through 

power house, 57 second-feet December 1.

DIVERSIONS. Water is diverted from the reservoir through a tunnel to the power 

house of Snow Mountain Water & Power Co. in Potter Valley and then 

wasted down a branch of Russian River.

REGULATION. Low-water flow completely diverted to power house; about 2 

second-feet wasted down South Eel River through the fishway and sluicje gate.

ACCURACY. Stage-discharge relation permanent when flashboards are not on 

dam. Rating curve well defined. Gage-height record good. Daily discharge ascertained by applying mean daily gage height to rating table except 

when flashboards are on dam when the average height of flashboards is subr 

tracted before applying to rating table. When sluice gate was open, 700 

second-feet were added to give total daily discharge. Combined monthly 

discharge is sum of flow over dam, through sluice gate a,nd through the tunnel. 

Records fair.
336 SURFACE WATEH SUPPLY, 1923, PART XI

The following discharge BasasuFement was mad* by WiHiam 

April22, 1923: Gage height, 4.67 feet (Baseboards on dam); discharge, 361

EEL BXVER AT SCOTIA, CAUF.

LOCATION, In sec. 18, T. 1 N., R. 1 E., at Wfldwood Bridge, half a mile northeast of Scotia, Humboldt County. Laribee Creek enters 14 miles above 

and Van Duzen River 7 miles below station.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. December 15, 1910, to February 6, 1913; October 1, 

1916, to September 30, 1923.

GAGE. Staff gage in eight sections, read by Millard Barisdale. Section No. 1 

is spiked to old cofferdam on northeast corner of footing of middle pier; 

No. 2 is painted on upstream and south corner of middle pier; No. 3 is 

painted on downstream and north face of footing of south pier; No. 4 is 

painted on vertical form brace at downstream end of south pier; No. 5 is 

painted on downstream face of south pier; No. 6 is painted on vertical post 

of first wooden bent of trestle; No. 7 is painted on vertical post of second 

bent of trestle; No. 8 is painted on vertical post of third bent of trestle. 

Former gages at this station were destroyed when suspension bridge was 

built in 1914 and when it was destroyed in 1915. The original datum has 

not been maintained, but the new datum probably does not differ more than 

a few tenths of a foot from the original.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Solid rock and gravel; fairly permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 26.9 feet at 

5 p. m. December 28 (discharge, 73,400 second-feet); minimum stage 

recorded, 8.40 feet at 4 p. m. September 18 (discharge, 60 second-feet).

1911-1923: Maximum stage recorded, 55.5 feet February 2, 1915 (discharge, from extension of rating curve, about 290,000 second-feet); minimum 

discharge, 40 second-feet September 9-11, 1920.

DIVERSIONS. Water is diverted from South Eel River by Snow Mountain 

Water & Power Co. and wasted down a branch of Russian River (see p. 342).

REGULATION. None.

ACCURACY. Stage-discharge relation not changed during year. Rating curve 

well defined. Staff gage read to hundredth^ twice daily. Daily discharge 

ascertained by applying mean daily gage height to rating table. Records 

good.

converge into one tailrace just above gage. Bottom and sides of tailrace 

are concrete. Tailrace is rectangular, 12 feet wide and 8 feet deep. Control 

is an 8 by 12 inch plank placed in weir guides to form a submerged weir.

EXTREMES OF DISCHARGE. Maximum mean daily discharge during the year, 317 

second-feet October 10-13.

DIVERSIONS. Water may be diverted from the tailrace above gage through two 

small ditches for irrigation in Potter Valley. None diverted this year.

REGULATION. Completely regulated by operation at power plant.

ACCURACY. Stage-discharge relation permanent. Rating curve very well 

defined. Float gage read to hundredths each time a change in load is made 

at power house. Daily discharge October 1 to November 30 computed 

from power output. Discharge December 1 to September 30 ascertained by 

plotting all available gage heights, estimating gage height graph, and using 

a discharge integrator. Records fair October and November, excellent 

December to September.

Water for the power plant is diverted from South Eel River at Van Arsdale 

Dam. The tailrace discharges into a tributary of Russian River.

KLAMATH RIVER BASIN 

WHIIAMSON BIVER ABOVE 8PEINQ CREEK, NEAE KLAMATH AGENCY, OHEQ.

LOCATION. In sec. 2, T. 34 S., R. 7 E., 8 miles north of Chiloquin, 2 miles above 

Spring Creek, and 6 miles northeast of Klamath Agency, Klamath County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. November 9, 1917, to September 30, 1919, and May 23, 

1920, to September 30, 1923. Stations maintained at Rocky Ford in sec. 

1, T. 33 S., R. 7 E., March 26, 1908, to June 30, 1910, and 5 miles above 

Spring Creek, May 1, 1912, to September 30, 1913, give practically the 

same record, except for a few second-feet inflow from springs below Rocky 

Ford.

ICE. Stevens continuous recorder on left bank. Inspected by J. A. McKeever.

DISCHARGE MEASUREMENTS. Made from cable 25 feet below gage or by wading 

at same section.

CHANNEL AND CONTROL. Bed composed of sand and gravel, fairly permanent; 

one channel at all stages. Control is riffle 200 feet below gage. Stagedischarge relation is probably affected by growth of aquatic plants.

EXTREMES OP DISCHARGE. Maximum stage during year from water-stage 

recorder, 2.58 feet at noon, April 6 (discharge, 810 second-feet); minimum 

stage from recorder, 0.06 foot October 10-13 (discharge, 17 second-feet) 

1917-1923: Maximum stage from water-stage recorder, 3.84 feet April 

13, 1919 (discharge, 1,220 second-feet). The flood of 1917, about April 27 

or 28, reached a stage of 5.65 feet, as determined by leveling to high-water 

marks (discharge, estimated by extension of rating curve, 2,500 secondfeet); minimum stage recorded, -0.19 foot July 26, 1920 (discharge,- 1& 

second-feet).

346 SURFACE WATER SUPPLY, 1923, PART XI

IQE. Stage-discharge relation not affected by ice.

DIVERSIONS. A large area of Klamath Marsh and adjoining lands are irrigated 

by natural flooding, and smaller areas by ditches.

REGULATION. None.

ACCURACY. Stage-discharge relation changed slightly during spring high water 

affecting only low stages; affected by drift on control November 1 to January 9; two fairly well-defined rating curVes used, identical above 45 secondfeet, shifting-control method used November 1 to January 9. Operation of 

water-stage recorder fairly satisfactory up to August 2 except for three 

short periods of quite uniform flow. Daily discharge ascertained by applying to rating table mean daily gage height determined by inspecting recorder 

graph. Records good, except for October to December, August, and 

September, for which they are fair.

' WILLIAMSON RIVER BELOW SPRAGUE RIVER, NEAR CHILOQUIN, OREG.

LOCATION. In sec. 3, T. 35 S., R. 7 E., one-fourth mile below mouth of Sprague 

River and three-fourths mile southwest of Chiloquin, Klamath County.

DRAINAGE AREA. 2,810 square miles.

RECORDS AVAILABLE. June 25, 1917, to September 30, 1922, and August 31 to 

September 30, 1923. The sum of discharge records at stations on Williamson 

and Sprague Rivers above their junction is directly comparable with these 

records.

GAGE. Friez water-stage recorder on left bank installed August 31 at new 

datum.

DISCHARGE MEASUREMENTS. Made from cable at gage section.

CHANNEL AND CONTROL. Rocky ledge and boulders; probably permanent.

EXTREMES OF DISCHARGE. Maximum daily discharge during year by combining 

records at stations above, 2,250 second-feet April 1; minimum stage from 

water-stage recorder, 2.44 foot at 2 p. m. September 5 (discharge, 502 

second-feet).

1911-1923: Maximum discharge, 7,300 second-feet April 27, 1917 (sum of 

discharges on that date at stations on Sprague River at Chiloquin, 4,490 

second-feet and Williamson River at Chiloquin, estimated 2,500 second-feet); 

minimum stage recorded. 0.35 foot at 6 a. m. October 14, 1920 (discharge, 

320 second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. Modoc Point Canal diverts from Sprague River above the station. 

Large areas of land are irrigated from the river and its tributaries.

REGULATION. Manipulation of gates of dam used for logging on Sprague River 

causes considerable fluctuation at times at the gage.

ACCURACY. Stage-discharge relation practically permanent for new gagB. 

Operation of water-stage recorder satisfactory. Daily discharge ascertained by applying to rating table mean daily gage height determined by 

inspecting gage height graph. Monthly means for October to August have 

been computed by adding discharge at station on Williamson River above 

Spring Creek and Sprague River at McCready ranch (p. 359) and estimating 

inflow, mostly from springs, as 35 to 40 second-feet to Sprague River, and 

290 to 330 second-feet to Williamson River. Records for September good, 

estimated monthly means, fair.

staff read about once a week to September 30, 1920, and daily since that 

date. Zero on gage is 4,135.93 feet above sea level as determined in October, 

1926. Gage readings 1918 to 1923 have been reduced to a datum of 4,100 

feet. Published elevations for an indefinite period prior to October 1, 1923, 

are 0.2 foot too high. During 1904 and 1905, vertical staff on Pelicaft Bay; 

zero 4,137.78 feet above sea level as determined by E: C. LaRue on June 

1920. All elevations Tefer to United States Bureau of Reclamation datum.
KLAMATH BIVEB BASIN 349

EXTREMES OP STAGE. Maximum stage recorded during year, 4,142.24 feet May

16; minimum stage recorded, 4,139.22 feet September 24. 

1904-1923: Maximum stage, 4,144.98 feet (United States Bureau of

Reclamation datum) about April 20, 1904, determined from high-water 

»m«jks May 28, 1904; minimum stage recorded, 4,139.13 feet October 5,

1920 (datum of October, 1926). 

FLUCTUATION. Gage heights are very much affected by wind. The water is

lowered near the outlet when the wind blows from the south and is raised

as much above its normal level when the wind is in the opposite direction.

There is a periodic oscillation when the wind blows for any length of time. 

REGULATION. Water stored by dam at outlet of lake, beginning April 15, 1919. 

COOPERATION. Gage-height record furnished by the California Oregon Power

Co. and United States Bureau of Reclamation.

LINE RIVER AT KLAMATH FALLS, OREG.

LOCATION. In NW. % sec. 32, T. 38 S., R. 9 E., one-fourth mile above county 

bridge over Link River, 1 mile below outlet of Upper Klamath Lake, and 

immediately above head of Lake Ewauna at Klamath Falls, Klamath 

County.

DRAINAGE AREA. 3,110 square miles.

RECORDS AVAILABLE. May 15, 1904, to September 30, 1923.

GAGE. Friez water-stage recorder on left bank; elevation of zero is 4,080.35 feet 

above sea level, Bureau of Reclamation datum, according to latest determination; inspected by Bureau of Reclamation engineers. Friez recorder on 

opposite bank and a little farther upstream was used June 6, 1908, to 

August 30, 1912. Chain gage on the bridge used 1904 to 1908.
350 SURFACE WATER SUPPLY, 1923, PART XI

DISCHAEGE MEAUREMENTS. Made from bridge, section deep, current sluggish at 

low water, bed composed of mud and sand.

CHANNEL AND CONTROL. Rock and boulder riffle a short distance below gage 

affords fairly permanent control. Water from tailrace of California Oregon 

Power Co.'s plant, which enters the river opposite the gage, appears to 

affect stage about the same as if it came down the river channel.

EXTEEMES OF DISCHARGE. Maximum stage during year from water-stage 

recorder, 7.18 feet at noon January 16 (discharge, 3,250 second-feet); 

minimum stage during year from recorder, 4.81 feet practically all day 

December 13 and 15 (discharge, 608 second-feet).

1904r-1923: Maximum stage, 7.30 feet at gage at bridge May 12, 1904, 

determined May 15, 1904, from high-water marks (discharge, 9,400 secondfeet); minimum stage, 4.07 feet, August 30, 1918, determined by leveling 

(discharge estimated as 22 second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. The main or "A" canal of the Klamath project of the United 

States Bureau of Reclamation diverts water from Link River immediately 

below Upper Klamath Lake. Record is kept of this diversion. (See 

p. 369). Some water is also diverted for irrigation from the tributaries to 

Upper Klamath Lake, but the total run-off is as yet only slightly affected.

REGULATION. Water stored in Upper Klamath Lake by dam beginning April 

15, 1919. Fluctuations caused by effect of wind on Upper Klamath Lake 

are much less marked than before dam was constructed. '

ACCURACY. Stage-discharge relation changing April 16 and 17. Two rating 

curves used fairly well defined. Water-stage recorder operated in satisfactory manner October 1-8, December 9-19, and 28-31, January 4 to August 

23. Staff gage readings, once a day used at other times. Daily discharge 

ascertained by applying to rating table mean daily gage height obtained by 

inspecting the recorder graph, or the daily gage reading. Records good.

KLAMATH RIVER AT SPENCER BRIDGE, NEAR KENO, OREG.

LOCATION. In SW. % sec. 31, T. 39 S., R. 7 E. at Spencer Bridge 1 mile below 

Spencer Creek, 6 miles below former station at Keno, and 18 miles west of 

Klamath Falls, Klamath County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. October 7, 1913, to September 30, 1923. Records' were 

obtained at Keno May 31, 1904, to December 31, 1913.

GAGE. Lietz water-stage recorder and staff gage on left bank about 500 feet 

below bridge used beginning September 1, 1923. Vertical staff near 

upstream end of first concrete pier at east end of bridge in NW. ^ sec. 32 

used to August 24, 1923. Gage readers Mrs. Roy F. Beck and employees of 

California-Oregon Power Co. Datum lowered 1.0 foot June 21, 1918, and 

0.54 foot July 16, 1921.

DISCHARGE MEASUREMENTS. Made from upstream side of wagon bridge.

CHANNEL AND CONTROL. Narrow channel confined by rock crib and timbers of 

former bridge, practically permanent. Wide even channel and control of 

heavy gravel and boulders at old gage.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 3.65 feet 

January 20 (discharge, 3,890 second-feet); minimum stage from water-stage 

recorder, 2.06 feet (1924 datum) at new location September 24 (discharge, 

770 second-feet).

1913-1923: Maximum stage recorded, 2.42 feet, original datum April 21, 

1914 (discharge, 5,130 second-feet); minimum stage recorded, 0.38 foot 

August 3, 1918 (discharge, 386 second-feet). A stage of 15.3 feet (discharge, 

9,250 second-feet) occurred at Keno station about May 10, 1904.

ICE. Stage-discharge relation affected by ice February 1-19.

DIVERSIONS. Only a small quantity of water diverted below Klamath Falls 

station. Practically all the flow of Lost River during the nonirrigating 

season is diverted into Klamath River below Klamath Falls by the Lost 

River diversion canal (pp. 370-371).

REGULATION. Water stored in Upper Klamath Lake by California Oregon 

Power Co., beginning April 15, 1919. Some natural regulation due to 

effect of wind on the wide flat stretches of river above Keno.

ACCURACY. Stage-discharge relation changed during ice period of January 1-19, 

also September 1 when station was moved. Three well defined rating curves 

used. Gage read to hundredths three times a week to January 23, daily 

January 25 to August 18, twice daily August 19 to September 30. Recorder 

operated September 7-30. Daily discharge ascertained by applying to 

rating table daily gage reading or mean gage height obtained by inspecting 

recorder graph. Records good beginning February 20, fair"prior to that.

GAGE. Vertical staff on left bank; read by L. F. Belknap.

CHANNEL AND CONTROL. Bed composed of sand and gravel; no definite control 

as stream is very sluggish for miles above and below gage; banks subject 

to overflow at a stage of about 5 feet and considerable water may flow in 

a cut-off across a bend to the right of the station.

DISCHARGE MEASUREMENTS. Made from cable about 100 feet below gage.

EXTREMES OF DISCHARGE. Maximum stage recorded during period and probably 

for year, 3.00 feet April 9 (discharge, 430 second-feet); minimum discharge 

recorded, 89 second-feet July 17 (gage height, 0.70 foot).

2,080 second-feet occurred at a station 2 miles downstream on May 21, 1904. 

ICE. Stage-discharge relation not seriously affected by ice, as stream is spring

fed.

DIVERSION. Considerable water is diverted near Ely for irrigation.

REGULATION. None.

ACCURACY. Stage-discharge relation changed during winter and affected by 

aquatic growth June to September. Rating curve used October 1 to November 10, poorly defined; rating curve used March 5 to May 31 fairly well 

defined; shifting-channel method used June 1 to September 1. Gage read 

to hundredths about three times a week except November 1 to March 15.

RECORDS AVAILABLE. May 13 to November 6, 1918, April 20 to August 31, 

1919, and March 20 to August 25, 1920, May 10 to August 31, 1921, and 

October 1, 1921, to November 25, 1923, when station was discontinued.

GAGE. Stevens continuous recorder installed October 14, 1921, on left bank of 

creek, about 1 mile above location of gage used in 1921 and 1% miles above 

gage used 1918 to 1920, No regular observer; recorder inspected only at 

time of visits by Geological Survey engineers.

DISCHARGE MEASUREMENTS. Made from foot-log 100 feet below gage or by 

wading.

CHANNEL AND CONTROL. Stream bed crooked and deep, vertical sod banks with 

scattered growth of willows; control is a gravel riffle 30 feet below gage.

EXTREMES OF DISCHARGE. Maximum stage during period October 1, 1922, to 

November 25, 1923, from water-stage recorder, 2.00 feet at 1 a. m. May 10 

(discharge, 111 second-feet); minimum stage, 0.39 foot at 8 p. m. August 18 

(discharge, 3.7 second-feet).

1918-1923: Maximum stage from recorder, 3.6 feet May 19, 1922 (discharge, 307 second-feet); minimum discharge that of 1923.

ICE. Stage-discharge relation evidently affected by ice from about December 1 

to April 7, discharge estimated from study of temperature records and estimated discharge at time of visit March 22 and records of other streams.

DIVERSIONS. None above station; water is spread over meadows below station 

by numerous dams.

REGULATION. None. '

ACCURACY. Stage-discharge relation apparently permanent. Rating curve well 

defined. Operation of water-stage recorder satisfactory for periods for 

which daily discharge is given, and December 1 to January 3, when stagedischarge relation was ice affected. Clock run down at other times. Daily 

discharge ascertained by applying to rating table mean daily gage height 

obtained by inspecting recorder graph. Discharge for estimated periods 

somewhat uncertain, but accuracy of yearly total is probably good.

ANNA CREEK NEAR FORT KLAMATH, OREG.

LOCATION. In sec. 36, T. 32 S., R. 6 E., at sawmill 3 miles below boundary of 

Crater Lake National Park and 6 miles northwest of Fort Klamath, Klamath County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. November 12, 1922, to September 30, 1923.

GAGE. Vertical staff on right bank, relocated May 4, 1923.

DISCHARGE MEASUREMENTS. Made from footbridge near gage or by wading.
KLAMATH RIVER BASIN 367

CHANNEL AND CONTROL. Gravel and cobbles, with some pumice sand and con* 

siderable accumulation of logs and drift.

EXTREMES OP DISCHARGE. Maximum discharge recorded during year, 108 second-feet July 14 (gage height, 1.83 feet); minimum stage recorded, 0.70 foot 

March 11 (discharge, 44 second-feet); discharge probably lower during ice 

period.

ICE. Stage-discharge relation affected by ice November 30, December 1, 7-19, 

December 30 to January 5, January 20-21, January 24 to February 19,

DIVERSIONS. None above station, much of the flow is diverted below for irrigation in the Wood River Valley.

REGULATION. May be regulated occasionally by operation of flashboards at 

log pond just above.

ACCURACY. Stage-discharge relation unstable, owing to change in drift on control. Fairly well defined rating curves used as follows: November 12 to 

December 31, January 1 to May 4, May 5 to July 14, and September 18-30; 

indirect shifting-control method used July 15 to September 17. Gage read 

to hundredths once a day. Daily discharge ascertained by applying daily 

gage reading to rating table. Discharge during ice periods estimated from 

study of observer's notes and temperature records. Records fair.

"A" CANAL AT KIAMATH PAHS, OREG.

LOCATION. In SE ]4= see. 29, T. 38 S., R. 9 E., below tunnel 1 mile below head

gates of canal near Klamath Falls, Klamath County. 

RECORDS AVAILABLE. Irrigation seasons, 1911-1923. Some water was diverted

for three or four years prior to 1911, but no record was kept. 

GAGE. Stevens 8-day water-stage recorder on right bank of canal just back of

Bureau of Reclamation office.* Recorder was located above weir above the

tunnel prior to 1923.

DISCHARGE MEASUREMENTS. Made from bridge just above present gage, formerly from a foot plank just inside lower end of tunnel, about half a mile

below old gage. 

CHANNEL AND CONTROL. Broad flat earth section; old gage was above a

trapezoidal weir, 18.15 feet long, with its crest, 7.27 feet above bottom of

canal. 

EXTREMES OF DISCHARGE. Maximum stage during year from water-stage

recorder, 7.90 feet July 31 to August 2 (discharge, 690 second-fecit); canal

dry each winter.

1911-1923: Maximum discharge, 773 second-feet June 28, 1922 (gage

height above weir, 4.83 feet); minimum discharge, zero. 

ACCURACY. Stage-discharge relation fairly permanent May 9 to August 28,

unstable thereafter. Fairly well-defined curve used, May 9 to August 28,

discharge estimated by ditch rider May 1-8, shifting-control method used

August 29 to September 30. Operation of water-stage recorder satisfactory.

Daily discharge ascertained by applying to rating table mean daily-gage

height obtained by inspecting recorder graph. Record good, except for

September, when it was fair. 

COOPERATION. Records furnished by United States Bureau of Reclamation.

"A" Canal diverts from Link River immediately below outlet of upper 

Klamath Lake in NE. M sec. 30, T. 38 S., R. 9 E. The water is used for irrigating lands east of Klamath River on both sides of Lost River. Most of the return 

water reaches Lost River.

to September 30, 1923. Records April 1, 1916, to September 30, 1918, 

obtained at a station referred to as "near Klamath Falls, Oreg."

OAGE. Vertical staffs showing height of water in pond back of head gates and 

in canal below gates, read once a day. Record beginning May 4 obtained 

at a recorder station located below spillway from C canal.

GATE OPENINGS. The head works of the canal comprise three hand-operated 

sliding gates, each 4 feet wide and 6 feet high. The gate openings are 

recorded each day. Water from Klamath River backs up the canal nearly 

to its head, even if no water is running.

CHANNEL AND CONTROL. Wide shallow canal, excavated in sand and silt; backwater from Klamath River extends practically to head of canal.

DISCHARGE MEASUREMENTS. Made from a footbridge a short distance below 

head gate.

DISCHARGE COEFFICIENTS. Tables of discharge coefficients and velocity for 

computing the flow through the gates considered as orifices have been obtained 

by plotting the coefficients determined from meter measurements.

EXTREMES OF DISCHARGE. Maximum discharge during the year, 319 second-feet 

March 26-28. Canal dry at times.

1912-1923: Maximum discharge, 508 second-feet, February028, 1914; 

minimum, canal dry.

DIVERSIONS. Beginning in June, 1922, water was wasted from the C-G canal 

into the diversion canal, and the amount estimated. Beginning May 4, 

1923, the station was located below the wasteway.

ACCURACY. Coefficients used in computing discharge through orifices are fairly 

well defined for March and April, poorly defined October to February. 

Operation of water-stage recorder fairly satisfactory; stage-discharge 

relation unstable; mean daily gage heights obtained by inspecting the 

recorder graph; daily discharge ascertained by shifting-control method. 

Records fair.

COOPERATION. Field data furnished by the United States Bureau of Reclamation.

is probably returned to the river above gage. Other small ditches divert 

above station.

REGULATION. Considerable diurnal fluctuation at the gage owing to irrigation 

above. Some water diverted for irrigation probably returns to river above 

the gage by seepage.

ACCURACY. Stage-discharge relation did not change during period of record 

during year. Rating curve well defined. Staff gage read to hundredths once 

daily April 7 to June 24 but record is fragmentary. Water-stage recorder 

record excellent June 26 to September 30. Daily discharge ascertained by 

applying mean daily gage height to rating table. Records fair April 7 toJune 24 and excellent June 26 to September 30.

COOPERATION. Gage-height record and results of several discharge measurements furnished by State division of water rights.

STREAM-GAGING STATIONS AND PUBLICATIONS 

RELATING TO WATER RESOURCES

INTRODUCTION

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 powers, 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, monographs, professional papers, 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 I. North Atlantic slope basins (St. John River to York River).

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

the Mississippi).

III. Ohio River Basin.

IV. St. Lawrence River Basin.

V. Upper Mississippi River and Hudson Bay Basins.

VI. Missouri River Basin.

VII. Lower Mississippi River Basin.

VIII. Western Gulf of Mexico Basins.

I.. Colorado River Basin. 

X. Great Basin.

XI. Pacific slope basins in California.

XII. North Pacific slope basins, published in three volumes:

A, Pacific slope basins in Washington and upper Columbia River

Basin.

B, Snake River Basin. 

C, Lower Columbia River Basin and Pacific slope basins in Oregon.

HOW GOVERNMENT REPORTS MAY BE OBTAINED OR CONSULTED

NOTE. No data regarding stream flow are given in the 15th and 17th annual reports.

The records at most of the stations discussed in these reports 

extend over a series of years and miscellaneous measurements at 

many points other than regular gaging stations have been made 

each year. 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 

1923. The data for any particular station will, as a rule, be found in 

the reports covering the years during which the station was main-, 

tained. For example, data for Machias River at Whitneyville, 

Maine, 1903 to 1921, are published in Water-Supply Papers 97, 124, 

165, 201, 241, 261, 281, 301, 321, 351, 381, 401, 431, 451,471, 501, and 

521, which contain records for the New England streams form 190& 

to 1921. Results of miscellaneous measurements are published by 

drainage basins.

GAGING STATIONS 395

In these papers and in the following lists the stations are arranged 

in downstream order. The main stem of any river is determined 

by measuring or estimating its drainage area that is, the headwater 

stream having the largest drainage area is considered the continuation of the main stream, and local changes in name and lake surface 

are disregarded. All stations from the source to the mouth of the 

main stem of the river are presented first, and the tributaries in 

regular order from source to mouth follow, the streams in each 

tributary basin being listed before those of the next basin below.

In exception to this rule the records for Mississippi River are 

given in four parts, as indicated on page 391, and the records for large 

lakes are taken up in order around the rim of the lake.

PRINCIPAL STREAMS .

The rivers draining into the Pacific Ocean from California include 

San Diego, San Dieguito, San Luis Rey, Santa Ana, San Gabriel, 

Los Angeles, Santa Ynez, Santa Maria, and Salinas Rivers, draining 

areas south of San Francisco Bay; San Joaquin River, whose chief 

tributaries are Kings, Merced, Tuolumne, Stanislaus, Calaveras, 

and Mokelunme Rivers; Sacramento River, whose principal tributaties are Pit, Feather, and American Rivers; and Russian, Eel, Mad,

into Goose Lake, at the head of Pit River, all the streams in this 

division are entirely in California.

In addition to the list of gaging stations and the annotated list of

GEOLOGIC FOLIOS

Under the plan adopted for the preparation of a geologic map of the United 

States the entire area is divided into small quadrangles, bounded by certain 

meridians and parallels, and these quadrangles, which number several thousand, 

are separately surveyed and mapped.1 The unit of survey is also the unit of 

publication, and the maps and description of each quadrangle are issued in the 

form of a folio. When all the folios are completed they will constitute 

the Geologic Atlas of the United States. A folio is designated by the name 

of the principal town or of a prominent natural feature within the quadrangle. 

Each folio includes maps showing the topography, geology, underground 

structure, and mineral deposits of the area mapped and several pages of descriptive text. The text explains the maps and describes the topographic and 

geologic features of the country and its mineral products. The topographic 

map shows roads, railroads, waterways, and, by contour lines, the shapes of the 

hills and valleys and the height above sea level of all points in the quadrangle. 

The areal-geology map shows the distribution of the various rocks at the surfaces. The structural-geology map shows the relations of the rocks to one another 

underground. The economic-geology map indicates the location of mineral 

deposits that are commercially valuable. The artesian-water map shows the 

depth to ground-water horizons. Economic-geology and artesian-water maps are 

included in folios, if the conditions in the areas mapped warrant their publication. The folios are of special interest to students of geography and geology 

and are valuable as guides in the development and utilization of mineral resources.

All the folios contain descriptions of the drainage of the quadrangles. The 

folios in the following list contain also brief discussions of the underground waters 

in connection with the economic resources of the areas and more or less information concerning the utilization of the water resources.

An asterisk (*) indicates that the stock of the folio is exhausted. '
