SURFACE WATER SUPPLY OF PACIFIC SLOPE .BASINS 

Itf CALIFORNIA, 1919 AND 1920,

AUTHORIZATION AND SCOPE OF WORK.

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

measurements of flow made on streams in the United States during 

the years ending September 30, 1919 and 1920.

The data presented in these reports were collected by the United 

States Geological Survey under the following authority contained in 

the organic law (20 Stat. L., p. 394) :

Provided, That this officer [the Director] shall have the direction of the Geological 

Survey and the classification of public lands and examination of the geological structure, mineral resources, and .products of the national domain.

The work was begun in 1888 'hi connection with special studies 

relating to irrigation in the arid West. Since the fiscal year ending 

June 30, 1895, successive sundry civil bills passed by Congress have 

carried the following item and appropriations :

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

for the investigation of underground currents and artesian wells, and for the preparation of reports upon the best methods of utilizing the water resources.

In the execution of the work many private and State organizations 

have cooperated, either by furnishing data or by assisting ia collecting 

data. Acknowledgments for cooperation of the first kind are made 

in connection with the description of each station affected; cooperation of the second kind is acknowledged on pages 9 and 10.

Measurements of stream flow have been made at about 5,000 points 

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

Hawaiian Islands. In July, 1920, 1,350 gaging stations were 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.

DEFINITION OF TERMS.

The volume of water flowing in a stream the "runi-off" or "discharge" is expressed in various terms, each of which has become 

associated with a certain class of work. These terms may be divided 

into two groups (1) those that represent a rate of flow, as secondfeet, gallons per minute, miners' inches, and discharge in secondfeet per square mile, and (2) those that represent the actual quantity 

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

The principal terms used in this series of reports are second-feet, 

second-feet per square mile, run-off in inches, and acre-feet. They 

may be defined as follows:

"Second-feet" is an abbreviation for "cubic feet per second." 

A second-foot is the rate of discharge of water flowing in a channel 

of rectangular cross section 1 foot wide and 1 foot deep at an average 

velocity of 1 foot per second. It is generally used as a fundamental 

unit from which others are computed.

"Second-feet per square mile" is the average number of cubic feet 

of water flowing per second from each square mile of area drained, 

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

regards time and area.

"Run-t>ff in inches" is the depth to which an area would be covered if all the water flowing from it in a given period were uniformly 

distributed on the surface. It is used for comparing run-off with 

rainfall, which is usually expressed in inches.

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

required to cover an acre to the depth of 1 foot. The term is commonly used in connection with storage for irrigation.

The following terms not in common use are here defined:

"Stage-discharge relation;" an abbreviation for the term "relation 

of gage height to discharge."

"Control;" a term used to designate the 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 given gaging station is that point 

on the gage the gage height to which the surface of the stream 

falls when the discharge is reduced to zero.

EXPIiANATION OF I>ATA.

The data presented in this report cover the two years beginning 

October 1, 1918, and ending September 30, 1920. At the beginning 

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 snow 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 

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 gage or from a water-stage recorder that 

gives a continuous record of the fluctuations. Measurements of discharge are made with a current meter. (See Pis. I, II.) The general 

methods are outlined in standard textbooks on the measurement of 

river discharge.

From the discharge measurements rating tables are prepared that 

give the discharge for any stage, and these rating tables, when applied 

to the gage heights, give the discharge from which the daily, monthly, 

and yearly means of discharge are determined.

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

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

records 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 records 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, artifical regulation, maximum and minimum 

recorded stages, and the accuracy of the records.

The table of daily discharge gives, in general, 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.
4 SURFACE WATER SUPPLY, 1919 AND 1920, PART XI.

If such stations are equipped with water-stage recorders, the mean 

daily discharge may be obtained by averaging discharge at regular 

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

instrument 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 r 

which are defined on page 2, are based.

ACCURACY OP FIELD DATA AND COMPUTED RESULTS.

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

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

of observation of stage, measurement 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) refinement 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 tables "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 depth 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"
PUBLICATIONS. 5

previously published 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 sections of the 

United States are located above most of the diversions from those 

streams, and the discharge recorded does not show the water supply 

available for further development, as prior appropriations below the 

stations must first be satisfied. 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 they represent the best information available.

The table of monthly discharge gives 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.

PUBLICATIONS.

Investigation of water resources by the United States Geological 

Survey has consisted in large part of measurements of the volume of 

flow of streams and studies of the conditions affecting that flow, but 

it has comprised also investigation of such closely allied subjects as 

irrigation, water storage, water powers, ground 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 annual reports, bulletins, professional papers, and 

monographs.

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:

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 table which follows gives, by years and drainage basins, the 

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

to 1920. The data for any particular station will in general be 

found in the reports covering the years during which the station was 

maintained. For example, data for Machias River at Whitneyville, 

Me., 1903 to 1920, are published in Water-Supply Papers 97, 124, 

165, 201, 241, 261, 281, 301, 321, 351, 381, 401, 431, 451, 471, and 

501, which contain records for the New England streams from 1903 

to 1920. Results of miscellaneous measurements are published by 

drainage basins.

COOPERATION.

Investigation of the water resources of California is being carried 

on by the United States Geological Survey in cooperation with the 

State in accordance with acts of the State legislature, approved 

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

empowering the State authorities to enter into contracts with the 

Director of the United States Geological Survey for the purpose of 

making topographic maps, gaging streams, and surveying reservoir 

sites and canal locations for the conservation and utilization of the 

flood and storm waters of the State. The work for the years 1919 

and 1920 was maintained in accordance with the contract approved 

by the State Board of Control and signed by W. F. McCIure, State 

engineer.

Additional funds for the maintenance of river measurement 

stations were furnished by the# State Water Commission of California. 

The members of the commission during the two-year period were 

A. E. Chandler, W. A. Johnstone, A. W. Mason, and C. H. Lee; 

W. D. Stephens, governor; and W. F. McCIure, State engineer. 

Josephine A. Patten is secretary.

The entire expense of the stream-flow investigations in Tuolumne 

River drainage 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 accordance 

with a contract between the board of supervisors, the United States 

Department of Agriculture (represented by the Forest Service through 

F. H. Fowler, district engineer, and the Weather Bureau, through 

Ford A. Carpenter and H. B. Hersey, meteorologists), and the United 

States Geological Survey. Los Angeles County pays all expenses of 

the field work, except services furnished by the Forest Service, the 

Weather Bureau, and the Geological Survey. The Geological 

Survey supervises the work and compiles all field data for publication.

The stations in the Santa Ana River basin are maintained in co* 

operation with San Bernardino, Riverside, and Orange counties 

through their boards of supervisors. Substantial cooperation is also 

furnished by the Weather Bureau. The cost of installing the equipment at a number of the stations was paid from a special appropriation disbursed by the State Water Commission.

Assistance in the maintenance of river-measurement stations was 

furnished by the United States Forest Service, United States Weather 

Bureau, United States Indian Office, United States Bureau of 

Fisheries, National Park Service, County of Los Angeles, Santa 

Barbara Water Commission, Volcan Land & Water Co., Cuyamaca 

Water Co., Southern California Edison Co., and Turlock, Modes to, 

Oakdale, and South San Joaquin irrigation districts.

10 SURFACE WATER SUPPLY, 1919 AND 1920, PART XI.

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

companies, and individuals who are interested in the water resources 

of California. This cooperation is acknowledged 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, State engineer. Financial 

cooperation was also furnished by the United States Indian Office, 

the Goose Lake Valley Irrigation Co., and the Talent Irrigation

District.

DIVISION OF WORK.

The data for stations in California were collected and prepared for 

publication under the direction of H. D. McGlashan, district engineer, 

assisted by William Kessler, F. C. Ebert, Charles Leidl, J. F. Kunesh, 

C. J. Emerson, T. G. Bedford, K. M. Kelley, Jarrett Oliver, C. W. 

Sopp, and H. J. Tompkins. fe

The data for stations in Oregon were collected and prepared for 

publication under the direction of F. F. Henshaw, district engineer, 

assisted by R. C. Briggs, J. J. Dirzulaitis, K. N. Phillips, J. W. Bones, 

and Wendell Dawson, and by H. W. Humphrey and W. L. Smith, 

hydrographers of the United States Reclamation Service.

GAGING-STATION RECORDS.

SWEETWATEB BIVEB BASEST. 

SWEETWATER RIVER NEAR DESCANSO, CALIF.

LOCATION. In SE. J sec. 25, T. 15 S., R. 3 E., at Ellis ranch, 2 miles below mouth 

of Guatay Creek and 1$ miles below Descanso, San Diego County.

DRAINAGE AREA. 43.7 square miles (measure?! on topographic maps).

RECORDS AVAILABLE. November 21, 1905, to September 30, 1920.

GAGE. Staff gage installed November 6, 1918, a short distance below intake of Ellis 

ditch, and just above new concrete control. Previous gages were at approximately the same location but at different datums. Read by H. D. Ellis and 

W. E. Ellis.

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

CHANNEL AND CONTROL. Channel is cut in sand and fine gravel; bed shifting. 

Banks are generally high and not likely to be overflowed. A group of large 

boulders below the gage acted as a partial control until November 6,1918, when a 

concrete control was built at the same location.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30,1919, 2.70 feet during April 5 (discharge, 28 second-feet); minimum stage, 

1.32 feet at 5 p. m. July 21 (discharge, 0.1 second-foot).

Maximum stage recorded during year ending September 30, 1920, 4.70 feet at 

5 p. m. February 22 (discharge, 463 second-feet); minimum stage, 1.40 feet at 

5 p. m. September 3, 4, and 6 (discharge, 0.2 second-foot).

1905-1920: Maximum stage recorded, not known, occurred January 27, 1916 

(discharge, estimated from slope data, 9,870 second-feet); stream dry during a 

part of the years 1910,1911,1913, and 1916.

DIVERSIONS. About 0.3 second-foot is diverted above gage for irrigation on Ellis 

ranch.

REGULATION . None.
SWEETWATER RIVER BASIN. 11

ACCURACY. Stage-discharge relation not permanent. Five fairly well defined rating 

curves were used during the two years, and discharge was computed by shiftingcontrol method for a few short periods. Gage read to hundredths twice a day. 

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

Discharge for period of no gage heights was estimated from records on other 

streams. Records fair.

SURFACE WATER SUPPLY, 1919 AND 1920, PABT XI. 13

SAN DIEGO RIVER BASIN. 

SAN DIEGO RIVER NEAR SANTEE, CALIF.

LOCATION. In El Cajon grant, at old Mission dam, below Spring Canyon and just 

above Oak Canyon, 4| miles west of Santee, San Diego County.

DRAINAGE AREA. 375 square miles (measured on topographic maps).

RECORDS AVAILABLE. May 25,1912, to September 30,1920 (record not complete).

GAGE. -Staff in two sections installed December 12,1916. Lower section is bolted to 

upstream face of old dam near left end. Upper section fastened to large sycamore 

tree on left bank just above dam. Original location and datum have been maintained. Zero of gage is 266.42 feet above sea level, United States Geological Survey datum. Gage read by Thomas Netting.

DISCHARGE MEASUREMENTS. Made from cable about 500 feet above gage or by wading.

CHANNEL AND CONTROL. Bed is shifting sand. The old Mission dam serves as partial 

control.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30,1919, probably 6.20 feet at 8 a. m. March 22 (discharge, 99 second-feet); stream 

dry during October to January and June to September, except for a small quantity 

of ground water rising to the surface at the dam.

Maximum stage recorded during year ending September 30,1920, 10.8 feet during night of March 26 to 27 (discharge, 1,580 second-feet); stream dry during 

summer.

1912-1920: Maximum stage recorded, 25.1 feet January 27, 1916 (discharge, 

70,200 second-feet); stream practically dry for several months each year.

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 practically permanent. Rating curve used for 

October 1,1918, to February 21, 1920, is fairly well defined and after March 23, 

1920, well defined. A slightly different curve due to temporary changes in control 

was used February 22 to March 22, 1920. Gage read usually to half-tenths once 

a day. Daily discharge ascertained by applying gage height to rating table. 

The discharge was probably very small on all days when gage was not read. 

Records good for period covered by gage-height record.

COOPERATION. Gage-height record and results of several discharge measurementa 

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

SAN DIEGO RIVER BASIN. 15

BOULDER CREEK NEAR JULIAN, CALIF.

LOCATION. In Cuyamaca grant, at outlet of Cuyamaca reservoir, 7 miles south of 

Julian, San Diego County, and 12 miles above mouth of Boulder Creek.

DRAINAGE AREA. 12.0 square miles (measured on topographic map).

RECORDS AVAILABLE. June 19, 1912, to September 30, 1920.

GAGE. Vertical staff on right side of weir box, 3^ feet above weir. Zero at elevation 

of crest of the 6-foot Cippoletti weir, which is 100 feet below outlet gates of reservoir. Gage read by watchman at dam.

DISCHARGE MEASUREMENTS. Made by wading near weir. On account of velocity of 

approach, it has been necessary to rate weir.

CONTROL. Cippoletti weir acts as permanent control.

EXTREMES OP DISCHARGE. Maximum mean daily discharge reported during year 

ending September 30, 1919, 14.7 second-feet June 23 to July 16; stream dry 

December to April.

Maximum mean daily discharge reported during year ending .September 30, 

1920, 17.5 second-feet July 29 to August 1; stream dry December to May.

1912-1920: Maximum mean daily discharge recorded occurred January 28, 1916 

(discharge, 1,877 second-feet). No water is released from reservoir except when 

needed for Cuyamaca Water Co.'s flume.

DIVERSIONS. None.

REGULATION. Flow completely regulated by operation of outlet gate of reservoir. 

Cuyamaca dam, completed in 1886, was one of the first earth dams built in 

California to store water for irrigation. The dam was originally 35 feet high but in 

1894 was enlarged, increasing the capacity of the reservoir to 11,400 acre-feet. 

The present dam is 635 feet long and 41£ feet high, with an inner, slope of 2:1 

and an outer slope of li :1. From the reservoir the water flows 12^ miles down the 

natural channel of Boulder Creek and San Diego River to the intake of Cuyamaca 

Water Co.'s flume.

ACCURACY. Stage-discharge relation permanent except when changes are made in 

weir. A new rating was made in 1920, giving results only slightly different from 

the preceding one. Gage read daily to hundredths; additional observations are 

made when reservoir gates are changed. Records excellent when discharge does 

not exceed capacity of weir.

COOPERATION. Results of discharge measurements and record of daily discharge 

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

Sept. SO, 1920.

CUYAMACA WATER CO.'S FLUME AT DIVERTING DAM, NEAR LAKESIDE. CALIF.

LOCATION. In SE. \ sec. 11, T. 14 S., R. 2 E., just below intake at diverting dam, 

13 miles northeast of Lakeside, San Diego County.

KECORDS AVAILABLE. June 1, 1912, to September 30, 1920.

GAGE. Vertical staff in a stilling box on outside of flume, about 1,000 feet below 

intake, installed April 8, 1916. Part of the flume was rebuilt October 7 to 14, 

1919, and a new gage installed October 15 at approximately same location and 

datum. Original gage was similar but was 500 feet below intake and just above 

sand box. 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 lined with tar paper to reduce leakage.

EXTREMES OP DISCHARGE. 1912-1920: Maximum daily discharge 51 second-feet, 

March 24, 1913. No flow for certain periods nearly every year.

ACCURACY. Stage-discharge relation permanent from 1916 to October 6, 1919, when 

flume section was rebuilt. Two fairly well defined curves used after that date, 

a slight shift being caused by growth of aquatic plants. Gage read to hundredths 

three times daily. Daily discharge ascertained by applying mean daily gage 

height to rating table. Records fair.

COOPERATION. Gage-height record and results of several discharge measurements 

furnished by Cuyamaca Water Co.

Cuyamaca Water Co.'s flume, which diverts water from San Diego River and receives water from South Fork of San Diego River, is more than 30 miles long, 6 feet 

wide, and 24 inches deep. It discharges into La Mesa reservoir, about 8 miles northeast of San Diego. This system 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 service. The Capitan 

Grande Indian Reservation has a water right of 0.8 second-foot from this flume.

20 SURFACE WATER SUPPLY, 1019 AND 1920, PART XI.

CUYAMACA WATER CO.'S FLUKE NEAR LAKESIDE, CALIF.

LOCATION. At patrolman's cabin, half a mile above trestle crossing at Los 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, 1920.

GAGE. Vertical staff in a stilling box fastened to outside of flume just below patrolman's cabin at same site as water-stage recorder used from 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 the fall of 1914 the flume was deepened 8 inches and 

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

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

1918.

EXTREMES OP DISCHARGE. 1907-1920: Maximum mean daily discharge, 25 secondfeet, February 16, 1918. No flow during certain periods every year.

ACCURACY. Stage-discharge relation changed when flume was emptied December 1,

1919. probably for repairs, and about August 1, 1920, owing to growth of aquatic 

plants. Two fairly well-defined rating curves were used during the year. Gage 

read to hundredths three times daily. Daily discharge ascertained by applying 

mean daily gage height to rating table. Records fair.

COOPERATION. Gage-height record and results of several discharge measurements 

were furnished by Cuyamaca'Water Co.

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 17. .

to overflow.

EXTREMES OF DISCHARGE. Maximum stage during year Riding September 30, 

1919, from water-stage recorder, 2.35 feet at 6 p. m. March 14 (discharge, 192 

second-feet); minimum stage, from water-stage recorder, 0.81 foot August 30 

(discharge, not known).

Maximum stage during year ending September 30, 1920, from water-stage 

recorder, 3.45 feet at 5.30 p. m. August 2 (discharge, 820 second-feet); minimum 

stage from water-stage recorder, 0.83 foot at 6.30 p. m. September 4 (discharge, 

estimated 0.1 second-foot).

1912-1920: Maximum stage recorded, 11.0 feet January 27, 1916 (discharge, 

21,100 second-feet); stream dry October 1 to 2, 1913: August 12 to 29; and 

September 6 to 13, 1914.
SAN DIEGUITO KIVEE BASIN. 23

DIVERSIONS. No large diversions above the station.

REGULATION. None.

ACCURACY. Stage-discharge relation changes frequently.. Rating curves are fairly 

well defined. The operation of the water-stage recorder was satisfactory except 

October 1 to November 16, 1919, and a few other short periods of less than a 

week, when staff gage readings were used. Daily discharge ascertained by 

applying mean daily gage height to rating curve, by shifting-control method, 

and for the period May to September, 1920, by interpolation between measurements. On account of small discharge and lack of measurements, mean monthly 

discharge was estimated June to September, 1919, by comparison with record 

for Santa Ysabel Creek near Ramona.. Records fair for extreme low water and 

good for remainder of record.

COOPERATION. Results of several discharge measurements furnished by Volcan 

Land & Water Co.

o Estimated by comparison with record for Santa Ysabel Creek near Ramona. 

SANTA YSABEL CREEK NEAR RAMONA, CALIF.

LOCATION. In NE. £ NE. J sec. 27, T. 12 S., R. 1E., at Pamo dam site at lower end of

Pamo Valley, 1| miles below mouth of Temescal Creek and 4J miles north of

Ramona, San Diego County.

DRAINAGE AREA. 110 square miles (measured on topographic maps). 

RECORDS AVAILABLE. February 5, 1912, to September 30, 1920. 

GAGE. Vertical staff, known as gage "C," fastened to outside of automatic gage well

on left bank at dam site, has been used since December 1, 1917. Gage read by

C. M. DeVenelle and A. M. King. Original gage was a staff in four sections on left

bank, half a mile upstream. 

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

wading. 

CHANNEL AND CONTROL. Banks high and clean; channel straight for 200 feet above

and 600 feet below gage; bed is shifting sand. 

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September

30, 1919, 2.10 feet at 5 p. m. March 14 (discharge, 110 second-feet); minimum

stage during July, August, and September (discharge, 0.05 second-foot). 

Maximum stage recorded during year ending September 30, 1920, 4.60 feet at 5

p. m. March 26 (discharge, 740 second-feet); minimum stage, 1.72 feet at 5 p. m.

October 6 and 7 (discharge estimated, 0.1 second-foot). 

1912-1920: Maximum stage recorded, 14.0 feet, January 27, 1916 (discharge,

28,400 second-feet); minimum discharge, 0.05 second-foot during July, August,

and September, 1919. 

DIVERSIONS. No large diversions above the station. Water is diverted from Santa

Ysabel Creek near the mouth of the canyon, 5 miles below the station, by East

San Pasqual ditch, which takes out on the left bank, and West San Pasqual ditch,

which takes out on the right bank and below the intake of East San Pasqual ditch. 

REGULATION . None. 

ACCURACY. Stage-discharge relation changes frequently. Staff gage read to hundredths twice daily. Fairly well-defined rating curves used October 1 to Novem22925 23 WSP 511-
26 SURFACE WATER SUPPLY, 1919 AND 1920, PART XI.

ber 13,1918, and January 1 to March 30, 1919. Daily discharge for these periods 

ascertained by applying mean daily gage height to rating table, and for other 

periods by direct application to curve or by shifting-control method. During 

low water, discharge was obtained mainly by interpolation between measurements. Mean monthly discharge for November and December, 1918, estimated 

from record for Santa Ysabel Creek near Mesa Grande. Records good. 

COOPERATION. Results of most discharge measurements furnished by Volcan Land & 

Water Co.

SANTA MARIA CREEK NEAR RAMONA, CALIF.

LOCATION. In SE. £ sec. 11, T. 13 S., R. 1W., 7 miles below mouth of Hatfield Creek

and b\ miles west of Ramona, San Diego County. 

DRAINAGE AREA. 57.3 square miles (measured on topographic map). 

RECORDS AVAILABLE. November 6, 1912, to September 30, 1920, when station was

discontinued. 

GAGE. Friez water-stage recorder with concrete well and house on left bank just

above control. Original datum has been maintained.

DISCHARGE MEASUREMENT. Made from cable 370 feet below gage or by wading. 

CHANNEL AND CONTROL. Bed is shifting sand. Concrete control just below gage at

an outcropping of solid rock was rebuilt during summer of 1916. Zero flow

occurs at about 1.70 feet engage. Left bank high; right bank sloping; one channel

all stages. About 1,000 feet below gage valley narrows to a rocky gorge at

proposed dam site. On this account there is natural storage in the channel

during high water. 

EXTREMES OF DISCHARGE. Maximum stage during year ending September 30, 1919,

from water-stage recorder, 2.5 feet at 11 p. m. March 21 (discharge, 38 second-feet);

stream dry October 1 to November 15 and July to September, except for a very

small quantity of ground water brought to the surface at the concrete control. 

Maximum stage diiring year ending September 30, 1920, from water-stage

recorder, 3.45 feet at 1 p. m. March 26 (discharge, 198 second-feet); stream dry

during summer. 

1912-1920: Maximum stage recorded, 15.9 feet at 5 p. m. January 27, 1916

(discharge, 7,140 second-feet); stream practically dry for several months each

year.
32 SURFACE WATEE SUPPLY, 19fL0 AJTD 192», PART XI.

DIVERSIONS . None.

REGULATION . None.

ACCURACY. Stage-discharge relation practically permanent. The rating curve for 

the previous year was used for the year ending September 30,1919, as no measurements were made. A slightly different rating curve which is well defined was 

developed from nine measurements made during the year ending September 30, 

1920. Operation of the water-stage recorder satisfactory except March 8 to 14, 

1919, when no record was obtained, owing to someone disturbing the instrument. 

Discharge for this period estimated by comparison with flow of Santa Ysabel Creek 

near Ramona. Daily discharge ascertained by applying to the rating table mean 

daily gage height determined by inspecting recorder graph, except March 22 and 

26, 1920, when hourly discharge was averaged. Records fair for 1919 and good 

for 1920.

COOPERATION. Gage-height record and results of most discharge measurements furnished by Volcan Land & Water Co.

SANTA ANA 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 AREA. Not measured.

RECORDS AVAILABLE. January 31, 1919, to September 30, 1920.

GAGE. Stevens continuous water-stage recorder, installed in concrete well and 

house, on left bank at county line.

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 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 lowwater channel.

EXTREMES OF DISCHARGE. Maximum stage during period January 31 to September 

30, 1919, from water-stage recorder, 2.37 feet at 3 a. m. March 15 (discharge, 770 

second-feet); minimum stage, from water-stage recorder, 1.21 feet at 8 p. m. 

July 15 (discharge, 41 second-feet).

Maximum stage during year ending September 30, 1920, from water-stage 

recorder, 5.45 feet at 3.30 a. m. February 23 (discharge from extension of rating 

curve, 7,560 second-feet); minimum stage, from water-stage recorder, 0.93 foot 

at 10 p. m. August 5 (discharge, 45 second-feet).

DIVERSIONS. Numerous water companies divert water from main river and its.tributaries both above and below station. Large quantities of water are taken out of 

underground storage by flowing wells and pumping plants.
44 SURFACE WATER SUPPLY, 1919 AND 1920, PART XI.

REGULATION. Storage has been developed at Big Bear reservoir in upper Santa Ana 

River basin and at Hemet reservoir in San Jacinto River basin. Lake Elsinore 

receives the run-off from San Jacintp River basin, and discharges into Temescal 

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

pp, 79-80.)

ACCURACY. Stage-discharge relation not permanent; changes in control are slight 

during low stages. Record from water-stage recorder satisfactory. Mean daily 

gage height determined by inspecting recorder graph. Daily discharge ascertained by. applying mean daily gage height to rating tables, to curves covering 

short periods, or by shifting-control method. Hourly discharge was averaged 

February 8 and 23, March 2 and 22,1920. Measurements were made.frequently; 

records are good for this type of station.

LOWER SANTA ANA RIVER.

For comparative purposes, discharge measurements were made on the same days, 

during the irrigation season of 1919, at Los Angeles & Salt Lake Railroad bridge, about 

4 miles southwest of Riverside; at Atchison, Topeka & Santa Fe Railway bridge, about 

1 mile southwest of Prado (Rincon); and at the gaging station at Riverside-Orange 

County line, about 3 miles southwest of Prado. (See station description, pp. 43-44.)

These measurements were continued during the irrigation season of 1920. In August 

and September additional measurements were made at Rubidoux Bridge, Hamner 

Avenue Bridge, and intake of Anaheim Union and Santa Ana canals.

The results of these measurements are given in the following table:

SOUTHERN CALIFORNIA EDISON CO.'S CANAL 1 AND GREENSPOT PIPE LINE NEAR

MENTONE. CALIF.

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

canyon, 2f miles below intake on Santa Ana River, and 3 miles northeast of 

Mentone, San Bernardino County.

RECORDS AVAILABLE. 1896 to September 30, 1920.

DISCHARGE. Canal discharge' computed from records showing kilowatt output of 

power plant. Discharge of pipe line computed from weir record at forebay.

EXTREMES OF DISCHARGE. 1896-1920: Maximum mean daily canal discharge recorded, 97 second-feet March 16,1905; no flow during short periods nearly every 

year.

DIVERSIONS. 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.

ACCURACY. The record for power canal is computed on the assumption that 1 secondfoot develops 18.9 kilowatts. The weir record for the pipe line is considered good.

COOPERATION. Record furnished by Southern California Edison Co. through H. W. 

Dennis, chief engineer.

The intake of this canal is at Southern California Edison Co.'s power plant No. 2, 

2| miles above the Mentone plant at the mouth of the canyon. All the water, except 

that taken by the Greenspot pipe line, is first used for the development of power. 

After it leaves the Mentone power house it is conducted 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.

i Canal owned by Pacific Light & Power Corporation prior to 1917.

SANTA ANA RIVER BASIN. 51

MILL CREEK NEAR CRAFTONVILLE, 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 AREA. Not measured.

RECORDS AVAILABLE. January 21, 1919, to September 30, 1920.

GAGE. Gurley printing water-stage recorder on left bank just above Southern California Edison Co.'s concrete diversion dam used to September 27, 1919, and 

then replaced by a Gurley 8-day graph water-stage recorder.

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 the dam.

EXTREMES OP DISCHARGE. Maximum mean daily discharge recorded dxiring period 

January 21 to September 30, 1919, 18 second-feet March 21. All water diverted 

into canal No. 1 at various times during year.

Maximum stage recorded during year ending September 30, 1920, 2.00 feet 

(staff gage) on the morning of February 22 (discharge, from extension of rating 

curve, 650 second-feet). All water diverted into canal No. 1 at various times 

during year. \

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

Power canal No. 2 heads about 3 mile? 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. 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 fxirnish sufficient water for plant No. 1.

ACCURACY. Stage-discharge relation not permanent. Three fairly well defined 

rating curves were used. Operation of water-stage recorder fairly satisfactory. 

Daily discharge ascertained by applying mean daily gage height to rating tables, 

interpolating between measurements, or by shifting-control method. The discharge of Mill Creek is combined with that for power canal No. 1 and power 

canals Nos. 2 and 3 to give the total flow of Mill Creek. See pages 55-58 for record 

of flow in canals. Record fair.

COOPERATION. Water-stage recorder attended by electrician of Southern California 

Edison Co.

DIVERSIONS. The East Highlands Orange Co. diverts water from Plunge Creek at 

several points, from 2 to 5 miles above s,tation. A small quantity of water is 

diverted about 200 feet above gage, and when not needed for irrigation is wasted 

back into creek just below control.

REGULATION. None.

ACCURACY. Stage-discharge relation not permanent. Three well defined rating 

curves used during period. The water-stage recorder did not operate during a few 

short periods, and the discharge was estimated from flow of Santa Ana River and 

precipitation records. Discharge estimated January 1 to February 7, 1920, on 

account of low flow. Daily discharge ascertained by applying to rating table 

mean daily gage height determined by inspecting water-stage recorder graph, 

except February 22, March 2 and 22, 1920, when hourly discharge was averaged.

LYTLE CREEK AND FONTANA PIPE LINE NEAR FONTANA, CALIF.

LOCATION. In NW. J sec. 6, T. 1 N., R. 5 W. (unsurveyed), one-fourth mile below 

Lytle Creek power plant of Southern California Edison Co., 4J miles above 

Fontana power plant, and 7J miles north of Fontana, San Bernardino County*

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. October 1,1918, to September 30, 1920.

GAGE. Gurley graph water-stage recorder in concrete well and house on left hank..

DISCHARGE MEASUREMENTS. Made from cable at gage or by wading.

CHANNEL AND CONTROL. Gravel and boulders; shifts at high stage.
SANTA ANA RIVER BASIN. 69

EXTREMES OP DISCHARGE. During the year ending September 30, 1919, all the 

flow of Lytle Creek was diverted past the station by the Fontana pipe line.

Maximum discharge during year ending September 30, 1920, 291 second-feet 

from discharge measurement, March 2.

DIVERSIONS. Water is diverted about 3 miles above gage in sec. 26, T. 2 N., R. 6 W., 

by Southern California Edison Co. for the Lytle Creek power plant. This water 

is then carried directly across the creek by a siphon to the headworks of the 

Fontana pipe line which serves the plant of the Fontana Power Co. situated in 

sec. 22, T. 1 N., R. 5 W., about 4A miles downstream. The Fontana Union 

Water Co. develops ground water by means of a tunnel above the headworks of 

the Fontana pipe line which is supplied to the pipe line, and also diverts water 

by means of a temporary diversion dam on Lytle Creek above Lytle Creek power 

plant into the Fontana pipe line in order to operate the Fontana plant at capacity 

when water is available. During low-water period water is pumped from gravels 

into the Lytle Creek power plant canal by Fontana Union Water Co.

ACCURACY. Daily discharge of Lytle Creek when there was flow past the station waa 

ascertained from discharge measurements, estimates of flow by the Southern 

California Edison Co., and by interpolation. The records for Lytle Creek and 

Fontana pipe line are combined to give total flow of the creek.

COOPERATION. Records of daily discharge of Fontana pipe line furnished by Southern 

California Edison Co.

Sept. SO, 1920.

SAN JACINTO RIVER NEAR ELSINORE, CALIF.

LOCATION. Near east line of sec. 9, T. 6 S., R. 4 W., 1\ miles above junction with

Elsinore Lake (low-water stage), one-fourth mile above highway crossing, and 2

miles southeast of Elsinore, Riverside County.

DRAINAGE AREA. 717 square miles (measured on topographic maps). 

RECORDS AVAILABLE. January 1, 1916, to September 30, 1920. 

GAGE. Vertical staff in two sections on right bank about one-fourth of a mile above

highway crossing; read by W. L. Wilhite. 

DISCHARGE MEASUREMENTS. Made from railway bridge three-fourths of a mile

below gage or by wading. 

CHANNEL AND CONTROL. Gravel and small boulders; practically permanent. One

channel at all stages.
SANTA ANA RIVER BASIN. 77

EXTREMES OP DISCHARGE. Maximum stage recorded during the year ending September 30, 1919, 1.40 feet at 10 a. m. March 17 (discharge, 6.5 second-feet); 

stream practically dry October 1 to November 16 and May 12 to September 30.

Maximum stage recorded during year ending September 30, 1920, 3.26 feet 

at 2 p. m. March 27 (discharge, 234 second-feet); stream dry for several months. 

1916-1920: Maximum stage recorded, 19.0 feet at 11 a. m. January 28, 1916 

(discharge, 14,000 second-feet); stream dry for several months each year.

DIVERSIONS. The Temescal Water Co. diverts water for irrigation above the station. 

Water is also diverted above San Jacinto for irrigation.

RKGULATION. Water is stored for irrigation at Hemet reservoir on South Fork of 

San Jacinto River.

ACCURACY. Stage-discharge relation not permanent. No measurements were made 

in 1919 and the rating curve for the previous year was used. Ten measurements 

in 1920 determine a new curve fairly well defined, differing slightly from the old 

below 50 second-feet, and with an increasing difference above that point. Gage 

read to hundredths once daily; numerous gaps in the record. Daily discharge ascertained by applying gage height to rating table and interpolating for days on 

which gage was not read. Records fair. .

SANTA ANA RIVER BASIN. 79

ELSINORE LAKE AT ELSINORE, CALIF.

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

RECORDS AVAILABLE. December 1, 1915, to September 30, 1920.

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.

EMnore 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 winter 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 

latter date. A history of the lake is published in United States Geological Survey 

Water-Supply Papers 426, 429, and 441.

EXTREMES OF DISCHARGE. Maximum stage during year ending September 30, 1919, 

from water-stage recorder, 1.42 feet at 6 p.m. November 26 (discharge, 1.6 secondfeet); minimum stage for year not known; discharge estimated 0.1 second-foot 

for periods during August and September.

Maximum stage during year ending September 30, 1920, from water-stage 

recorder, 2.89 feet at 2.30 a. m. March 2 (discharge, 99 second-feet); minimum 

discharge, 0.2 second-foot August 23 and 24, and September 1 to 5.

1917-1920: Maximum stage, from water-stage recorder, 4.00 feet at 3 p.m. 

March 7, 1918 (discharge, 362 second-feet); minimum stage not known (discharge 

estimated, 0.1 second-foot) for periods during August and September, 1919.

DIVERSIONS. The Southern California Edison Co. diverts water, about 1 mile above 

the station, for power development. (See p. 84.)
SANTA ANA RIVER BASIN. 81

REGULATION. None.

ACCURACY. Stage-discharge relation not permanent until concrete control was constructed. On account of slight changes in the control, three fairly well defined 

rating curves were used before September 30, 1919. Measurements made since 

define an excellent curve. Daily discharge ascertained by applying to the rating 

table mean daily gage height determined by inspecting recorder graph. Several 

short gaps occurred in the gage-height record; discharge for these periods was interpolated, or estimated from records of flow on adjacent streams. Records good.

COOPERATION. Water-stage recorder inspected by employee of Southern California 

Edison Co.

SAN GABRIEL RIVER BASIN.

SAN GABRIEL RIVER NEAR AZUSA, CALIF.

LOCATION. In NW. \ sec. 23, T. 1N., 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. 222 square miles.

RECORDS AVAILABLE. 1894 to September 30, 1920.

GAGE. Gurley graph water-stage recorder on left bank at rock point above ford. 

Original location of gage was just above ford at mouth of canyon. On account 

of frequent changes in channel it has been necessary to install numerous gages 

at points from 1,000 feet above ford to 600 feet below. Most of the gages used 

have been installed at independent datums.

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

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

EXTREMES OP DISCHARGE. Maximum stage during year ending September 30, 1919, 

from water-stage recorder, 4.98 feet at 3.30 p. m. February 11 (discharge, 230 

second-feet); stream dry at gage for several periods during the year.

Maximum stage during year ending September 30, 1920, from water-stage recorder, 7.93 feet at 4 a. m. March 2 (discharge, 3,750 second-feet); stream dry at 

gage for several periods during the year.

1894-1920: 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. Water was diverted through the tunnel about 500 feet 

above ford at various times. (For daily discharge of these canals see pp. 91 and 93.)

REGULATION. None.
GABRIEL RIVER BAS

ACCURACY. Stage-discharge relation not perm

well denned. Operation of water-stage recorder 

charge ascertained by applying to the rating table 

mined by inspecting recorder graph, except Febru 

when hourly discharge was averaged. Records go

.anent throughout year. Rating curves 

was satisfactory. Daily disnean daily gage height deterry 9, 22, and March 22, 1920,

intake on San Gabriel River and 1$ miles north of Azusa, Los Angeles County. 

RECORDS AVAILABLE. 1896 to September 30,1920. 

DISCHARGE. Computed from record showing kilowatt output of power plant, on the

assumption that a discharge of 1 second-foot develops 25 kilowatts. 

EXTREMES OF DISCHARGE. Maximum mean daily discharge during year ending

September 30, 1919, 92 second-feet during February, March, April, May, and

June. Canal dry February 5. 

Maximum mean daily discharge during year ending September 30, 1920, 95

second-feet during March and June. Canal dry February 23 to 26 and March

2 to 11. 

1896-1920: Maximum mean daily discharge recorded, 97 second-feet November

27, 1908; canal usually dry for a few days each year. 

ACCURACY. Records good.

Diversion dam for canal is on San Gabriel River in SE. £ SE.± sec. 31, T. 2 N., R.9 W., 

5 miles above gaging station on San Gabriel River at the mouth of the canyon near 

Azusa. The water is used for power development at a point about 1J miles north of 

Azusa and, after leaving the power plant, is divided and used for irrigation, part is 

discharged into Azusa-Covina canal and the remainder into Duarte canal. During 

the rainy season part of the water from the power plant is wasted back into San Gabriel 

River below the gaging station.

TUNNEL DIVERSION NEAR AZUSA, CALIF.

LOCATION. Near line between sees. 22 and 23, T. 1 N., R. 10 W., at weir box where 

water is divided between Azusa and Duarte canals, 1,000 feet northeast of Southern 

California Edison Co.'s power plant and 1J miles north of Azusa, Los Angeles 

County.

RECORDS AVAILABLE. October 1, 1917, to September 30, 1920.

GAGE, Vertical staff fastened to north wall of weir box at reference point used during 

1918. Elevation of reference point 3.40 feet, referred to gage datum. Gage 

read by B. Bunje.

DISCHARGE MEASUREMENTS. Made by wading near gage.

CHANNEL AND CONTROL. Concrete weir box. During part of year 1919 a 12-inch 

plank was placed on top of Azusa weir, and during 1920 the record was further 

complicated by also shutting off the Durate weir at times; for some periods both 

weirs were shut off and water reached Azusa canal through the sand box.

ACCURACY. Stage-discharge relation changed frequently owing to manipulation of 

weirs, especially during 1920. Rating curves fairly well defined. Gage read to 

half-tenths daily. Daily discharge ascertained by applying daily gage height 

to rating table when both weirs were open; at other times based on measurements. 

Records fair,

ISie intake of this canal is on San Gabriel River about 600 feet above United States 

Geological Survey gaging station on San Gabriel River near Azusa. Water is used to 

augment the irrigation supply obtained from the tailrace of the Southern California 

Edison Co.'s power plant and to provide a supply when the water is shut out of power 

canal.

ROGERS GREEK NEAR AZUSA, CALIF.

LOCATION. In southwest corner of sec. 14, T. 1 N., R. 10 W.. half a mile above mouth 

of creek, and 2\ miles north of Azusa, Los Angeles County.

DRAINAGE AREA. 6.4 square miles (measured on topographic map).

EECORDS AVAILABLE.- October 1, 1917, to September 30, 1920. (Discharge measurements only, May 8, 1916, to June 11, 1917.)

GAGE. Stevens continuous water-stage recorder on left bank at mouth of canyon, 

half a mile above junction with San Gabriel River.

DISCHARGE MEASUREMENTS. Made by wading or from cable about 150 feet below 

gage.

CHANNEL AND CONTROL. Boulders, gravel, and solid rock; fairly permanent. A 

new control was built about 30 feet above the natural control, during the summer 

of 1920.

EXTREMES or DISCHARGE. Maximum stage during year ending September 30, 1919, 

from water-stage recorder, 1.98 feet at 10 p. m. February 11 (discharge, 17 second 

feet); stream dry October 1 to November 5 and June 7 to September 30.

Maximum stage during year ending September 30, 1920, from water-stage 

recorder, 4.15 feet at 2 a. m. March 2 (discharge, 206 second-feet); stream dry 

during summer.

1917-1920: Maximum stage recorded, 5.25 feet at 11.30 p. m. March 10, 1918 

(discharge, 332 second-feet); stream dry several months each year.

DIVERSIONS. Beginning April 27, 1920, a pipe line has diverted an unknown quantity 

of water from a point about 40 feet above the gage. After April 30, 1920, this 

diversion is not included in tables. The capacity of this pipe line is 0.5 secondfoot.

REGULATION. None.

ACCURACY. Stage-discharge relation not permanent. Several fairly well-defined 

rating curves used. Daily discharge ascertained by applying to the rating table 

mean daily gage height determined by inspecting recorder graph, or on days of 

considerable fluctuation, by averaging hourly discharge. Records good.

SA1ST GABRIEL RIVER BASIN. 97

FISH CREEK NEAR DUABTE, CALIF.

LOCATION. In SW. i SW. £ aec. 15, T. IN., R. 10 W., three-fourths mile above 

mouth of canyon and 4 miles northeast of Duarte, Los Angeles County.

DRAINAGE AREA. 6.5 square miles (measured on topographic map).

RECORDS AVAILABLE. July 23 to September 30, 1916; and July 28, 1917, to September 30,1920.

GAGE. Gurley graph water-stage recorder in concrete well and house on left bank.

DISCHARGE MEASUREMENTS. Made by wading near gage.

CHANNEL AND CONTROL. Gravel and boulders; not permanent. Banks high and 

not subject to overflow. In 1918 a concrete control was built at an outcrop of 

bedrock a short distance below gage.

EXTREMES OF DISCHARGE. Maximum stage during year ending September 30, 1919, 

from water-stage recorder, 2.59 feet at 10.30 a. m. February 11 (discharge, 21 

second-feet); no flow July 27-31 and August 6 to September 26.

Maximum stage during year ending September 30, 1920, from water-stage 

recorder, 4.10 feet at 12.30 a. m. March 2 (discharge, 255 second-feet); minimum 

stage, from water-stage recorder, 1.53 feet August 17 and 18 (discharge, 0.01 

second-foot).

DIVERSIONS. None above.

REGULATION. None.

ACCURACY. Stage-discharge relation not permanent. Several fairly well-defined 

rating curves were used. Water-stage recorder operated satisfactorily. Daily 

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

determined by inspecting recorder graph, or on days of considerable fluctuation, 

by averaging hourly discharge. Records good.

SAWPIT CREEK NEAR MONROVIA, CALIF.

LOCATION-. In SE. \ NW. \ 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, 1920.

GAGE. Gurley graph water-stage recorder in concrete well and shelter, on left bank 

at east end of highway bridge.

BISCHARGE MEASUREMENTS. Made from bridge or by wading.

 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. Control is a concrete-boulder dam just below gage. In 1919 a dam was 

built a short distance above the gage, forming a pool for intercepting sand and 

gravel, which would otherwise collect in the channel at gage and change the 

velocity of approach.

EXTREMES OF DISCHARGE. Stream dry at gage throughout the year ending September 

30, 1919.

Maximum stage during year ending September 30, 1920, from water-stage 

recorder, 2.01 feet at 2 a. m. March 2 (discharge from extension of rating curve, 

58 second-feet); stream dry at gage for several months.

1916-1920: Maximum stage recorded, 2.65 feet March 10, 1918 (discharge, 256 

second-feet); 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. 102). During 

1919 the entire flow of the creek was diverted by the pipe line.
100 SURFACE WATEB SUPPLY, 1919 AND 1920, PART XI.

REGULATION . None.

ACCURACY. The measurements made during 1920 determine a new well-defined 

rating curve. Operation of water-stage recorder satisfactory. Daily discharge 

ascertained by applying to the rating table the mean daily gage height determined 

by inspecting recorder graph. Records good.

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

102 SURFACE WATER SUPPLY, 1919 AND 1920, PART XI.

MONROVIA PIPE LINE NEAR MONROVIA, CALIF.

LOCATION. Near southeast corner of sec. 14, T. 1 N., R. 11 W., 300 feet above settling 

reservoir at mouth of Sawpit Canyon, and 1^ miles north of Monrovia, Los Angeles 

County.

RECORDS AVAILABLE. May 18, 1916, to September 30,1920.

GAGE. Vertical staff in weir box; read by E. S. Armstrong, canyon guard.

DISCHARGE. Determined by two rectangular weirs, with end contractions; left weir, 

2.25 feet long; right weir, 2.26 feet long. Crest of left weir is at zero gage height; 

crest of right weir is 0.02 foot lower at one end. Rating table has been checked 

by current-meter measurements made at mouth of intake pipe in weir box.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 0:36 foot at 5 p. m. February 11 (discharge, 3.1 second-feet); minimum 

stage, 0.14 foot at 5 p. m. August 13 to September 26 (discharge, 0.8 second-foot).

Maximum stage recorded during year ending September 30, 1920, 0.40 foot 9 a. 

m. February 22 also 5 p. m. March 21 (discharge, 3.7 second-feet); minimum stage 

0.14 foot at 5 p. m. July 28 to August 24 (discharge, 0.8 second-foot).

1916-1920: Maximum stage recorded, 0.49 foot May 18 to 19, 1916 (discharge, 

5.0 second-feet); minimum stage, U.14 foot August 13 to September 26, 1919, and 

July 28 to August 24, 1920 (discharge, 0.8 second-foot).

ACCURACY. Stage-discharge relation considered permanent since backwater conditions for any stage are probably constant. Gage read to hundredths twice daily. 

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

Records excellent.

COOPERATION. Gage-height record furnished by city of Monrovia.

The Monrovia pipe line furnishes part of the water supply of Monrovia. It obtains 

its water from two branches of Sawpit Creek. Most of this water is collected by tunnels 

driven into the sides of the canyon.

Daily discharge, in second-feet, of Monrovia pipe line near Monrovia, Calif., for the years 

ending Sept. 30, 1919 and 1920.

GAGE. Gurley graph 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; permanent; 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. Zero flow, 

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

EXTREMES OF DISCHARGE. Maximum stage during year ending September 30, 1919, 

from water-stage recorder, 1.75 feet at 3.30 a. m. February 11 (discharge, 5.9 

second-feet); stream dry during part of September 16 and 17.

Maximum stage during year ending September 30, 1920, from water-stage recorder, 2.28 feet at 1.30 a. m. March 2 (discharge, 55 second-feet); minimum 

stage, from water-stage recorder, 0.84 feet several days in August and September 

(discharge, 0.03 second-foot).

1916-1920: Maximum stage recorded, 2.30 feet March 10, 1918 (discharge, 58 

second-feet); stream dry during part of each day, September 16 and 17, 1919.

DIVERSIONS. None above.

REGULATION. None.

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

Mean daily gage heights determined by inspection of water-stage recorder graph. 

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

except February 22, March 1 and 2, 1920, when hourly discharge was averaged. 

For periods not covered by gage-height record, discharge was estimated from 

record of flow of Santa Anita Creek. Records good.

SAN GABEIEL RIVER BASIN. 109

SAN DIMAS CHEEK NEAR SABT DIMAS, CALIF.

LOCATION. In SW. i NE. J 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, 1920. (Discharge measurements only, April 14 to September 4, 1916.)

GAGE. Gurley graph water-stage recorder, in concrete well and house, on left bank.

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

CHANNEL AND CONTROL. Bed consists of sand, gravel, and boulders; shifting. Control is low concrete dam built across channel just below gage. This dam was 

raised about 2 feet January 18-23, 1918. 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 high stages.

EXTREMES OP DISCHARGE. Maximum stage during year ending September 30, 1919, 

from water-stage recorder, 3.80 feet at 4.30 p. m. February 11 (discharge, 37 secondfeet); no flow September 16 and 17.

Maximum stage during year ending September 30, 1920, from water-stage 

recorder, 6.15 feet at 1.30 a. m. March 2 (discharge, from extension of rating curve, 

1,010 second-feet); minimum mean daily discharge estimated, 0.01 second-foot 

August and September.

1916-1920: Maximum stage recorded in 1920; stream dry during a part of October and November, 1916, and September, 1919.

DIVERSIONS. None above. The San Dimas Water Co. diverts water for irrigation 

150 feet below gage.

ACCURACY. Stage-discharge relation not permanent owing to flashboards in control 

notch at times, and to sand and gravel deposits at control. The several rating 

curves are fairly well defined. Daily discharge ascertained by applying to the 

rating table or directly to the curves the mean daily gage heights determined by 

inspecting recorder graph. For days of considerable fluctuation, hourly discharge was averaged. For periods not covered by gage-height record, discharge 

was interpolated or estimated from record of flow on Santa Anita Creek. Records 

good.

COOPERATION. San Dimaa Water Co. furnished attendant for water-stage recorder.

ending Sept. 30, 1919 and 1920.

DALTON CREEK NEAR GLENDORA, CALIF.

LOCATION. In center of sec. 21, T. 1 N., R. 9 W., at Glendora Irrigation Co.'s dam, 

one-fourth mile above mouth and 2£ miles northeast of Glendora, Los Angeles 

County.

DRAINAGE AREA. 7.5 square miles.

RECORDS AVAILABLE. December 1, 1919, to September 30, 1920.

GAGE. Stevens continuous water-stage recorder in concrete well and house on right 

bank.

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

CHANNEL AND CONTROL. Control is the rubble masonry dam. Crest of dam slopes 

from wings to center, being 5'feet lower at the center. Pool above dam has been 

filled with silt and control is not effective.

EXTREMES OP DISCHAKGE. Maximum stage during year, from water-stage recorder,' 

4.03 feet at 12.45 a. m. March 2 (discharge, from extension of rating curve, 525 

second-feet); no flow August 8 to September 30.

DIVERSIONS. The Glendora Irrigation Co. diverts water half a mile and \\ miles 

above the gage through a 10-inch pipe. A 12-inch pipe line diverts water at the 

control. The total diversion is measured over a 20-inch weir. (See record of 

diversion on p. 113.)

REGULATION . None.

ACCURACY. Stage-discharge relation changed frequently owing to collection of silt 

on the control. Drainage area was burned over during 1919 and excessive 

erosion during rainy se'ason brought down an unusual amount of silt. Waterstage recorder operated satisfactorily throughout year except for a time in March. 

Daily discharge ascertained by applying mean daily gage height to rating curves 

covering short periods of time, and estimated from the record of San Dimas 

Creek. Records poqr.

S&TON CREEK NEAR PASADENA, CALIF.

LOCATION. Near line between sees. 2 and 11, T. 1 N., R. 12 W., at mouth of canyon 

just above Mount Wilson toll bridge, 4 miles northeast of Pasadena, Los Angeles 

County.

DRAINAGE AREA. 6.5 square miles (measured on topographic map).

RECORDS AVAILABLE. March 1, 1918, to September 30, 1920.

GAGE. Gurley graph* water-stage recorder on left bank just above toll bridge-*,

DISCHARGE MEASUREMENTS. Made by wading near gage.

CHANNEL AND CONTROL. Gravel and boulders, fairly permanent; concrete control.

EXTREMES OF DISCHARGE. Maximum stage during year ending September 30, 1919, 

from water-stage recorder, 2.16 feet at 9 a. m. February 11 (discharge, 54 secondfeet); no flow for several months.

Maximum stage during year ending September 30, 1920, from water-stage 

recorder, 2.77 feet at 1.30 a. m. March 2 (discharge, 105 second-feet); no flow for 

several months.

1918-1920: Maximum stage recorded, 3.47 feet at 4 a. m. March 11, 1918 (discharge, 470 second-feet); no flow for considerable periods each year.

DIVERSIONS. The Precipice Canyon Water Co. diverts an unmeasured amount of 

water above the station.

REGULATION. None.

ACCURACY. Stage-discharge relation permanent. A new curve averaging all measurements was used for the year ending September 30, 1920. It is fairly well defined 

and differs slightly from previous curve. Daily discharge ascertayied by applying to the rating table mean daily gage height determined by inspecting recorder 

graph, except February 22 and March 2, 1920, when hourly discharge was averaged. Water-stage recorder operated satisfactorily. Records good.

and 4 miles northeast of San Fernando, Los Angeles County.

DRAINAGE AREA. 27. 9 square miles (measured on topographic maps),

RECORDS AVAILABLE. March 31, 1916, to September 30,-1920 (not complete).

GAGE. Gurley graph water-stage recorder, in concrete well and house, on left bank,, 

installed December 2, 1916. Previous gage was a staff fastened t& a boulder on 

left bank, 216 feet above water-stage recorder.

DISCHARGE MEASUREMENTS. Made from cable 20 feet above gage or by wading.

CHANNEL AND CONTROL. Bed consists of sand, gravel, and boulders; not permanent. 

Left bank is steep rock cliff; right bank is gently sloping and covered with brusht 

and trees. Control is a low boulder and concrete dam built across channel about T 

feet below gage.-

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, from water-stage recorder, 1.81 feet at 2 p. m. February 11 (discharge, 34 

second-feet); no flow for several months.

Maximum stage recorded during year ending September 30, 1920, from waterstage recorder, 5.79 feet at 4 a. m. March 22 (discharge from extension of rating 

curve, 1,330 second-feet); no flow during October and November 22 and 23.

1,440 second-feet); usually no flow for several months each year.

DIVERSIONS. None above station. Water is diverted just below control.

REGULATION. None.

ACCURACY. Stage-discharge relation not permanent on account of change made ia 

artificial control February 6, 1919, and shifting deposits of sand at control. The 

entire drainage area was burned over during September, 1919, and more than the 

usual amount of debris has been brought down since. Several well-defined rating 

curves were used. Daily discharge ascertained by applying to the rating tables 

mean daily gage height determined by inspecting recorder graph. Water-stage 

recorder operated satisfactorily. Records good.

TUJTTNGA CHEEK NEAR STTNLANDi CALIF.

LOCATION. Near center of sec. 32, T. 3 N., R. 13 W. (unsurveyed), at a partly constructed and abandoned dam, 2 miles above mouth of canyon, and 4 miles northeast of Sunland. Los Angeles County.

DRAINAGE AREA. 106 square miles (measured on topographic map).

RECORDS AVAILABLE. October 28, 1916, to September30, 1920. (Discharge measurements only, April 1 to August 27. 1916.)

GAGE. Stevens water-stage recorder on right bank above dam.

DISCHARGE MEASUREMENTS. Made from cable about 1,000 feet below gage or by 

wading.

CHANNEL AND CONTROL. Bed consists of gravel and boulders; appears permanent. 

Control is concrete dam, which has a recess in center of the top providing a lowwater channel about 20 feet long and 1 foot deep. A steel angle-is set in the recess 

near downstream face.

EXTREMES OF DISCHARGE. Maximum stage during year ending September 30, 1919 r 

from water-stage recorder, 1.92 feet at 11 a. m. February 11 (discharge, 136 second-- 

feet); minimum stage not known, as water-stage recorder was not in operation 

during the period of lowest water (discharge estimated as 0:1 second-foot, September 20 to 23).

Maximum discharge during year ending September 30, 1920; estimated as 

1,400 second-feet on March 22, by comparison with adjacent streams; minimumdischarge similarly estimated as 0.5 second-foot October 9 to 14 and December 2. 

1916-1920: Maximum stage recorded, 3.35 feet December 24, 1916 (discharge, 

from revised rating cruve denned by measurements in 1918, 1,960 second-feet); 

minimum stage not known (discharge estimated as 0.1 second-foot, September 20s 

to 23, 1919).

DIVERSIONS. Two or three ranches divert a part of the low-water flow for irrigation 

above the station. There are two small diversions between gage and mouth of 

canyon.

REGULATION. None.
LOS ANGELES KTVER BASIN. 119

ACCURACY. Stage-discharge relation not permanent owing to sand collecting at control. Frequent discharge measurements have been made which determine two rating curves, differing slightly; well denned below 200 second-feet and fairly well denned between 200 and 800 second-feet. Operation of the water-stage recorder not 

entirely satisfactory owing to difficulty in keeping intake pipe open. Discharge 

estimated for periods of no record by comparison with adjacent streams. Daily discharge ascertained by applying to the rating table mean daily gage height determined by inspecting recorder graph. High-water records fair; other records good.

Sept. SO, 1919 and 1920.

LOS ANGELES RIVER BASIN. 121 

HAINES CREEK NEAR TUJUNGA, CALIF.

LOCATION. In NE. J NE. \ sec. 18, T. 2 N., R. 13 W., 800 feet above mouth of canyon and 1J miles northeast of Tujunga, Los Angeles County.

DRAINAGE AREA. 1.2 square miles (measured on topographic map).

RECORDS AVAILABLE. February 7, 1917, to September 30, 1920.

3-AGE. Gurley graph water-stage recorder in concrete well and house, on right bank.

IISCHARGE MEASUREMENTS. Made by volumetric method when discharge is very 

small, and by wading on crest of dam. The gaging bridge, for use during high 

water is 4 feet upstream from dam.

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

permanent; both banks 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 

about 0.25 foot.

EXTREMES or DISCHARGE. Maximum stage during year ending September 30, 1919, 

from water-stage recorder, 0.73 foot at 4 a. m. February 11 (discharge, 0.81 secondfoot); minimum stage from water-stage recorder, 0.27 foot September 5 to 12 

(discharge, 0.01 second-foot).

Maximum stage during year ending September 30, 1920, from water-stage 

recorder, 1.16 feet at 8.30 a. m. March 22 (discharge, 4.0 second-feet); minimum 

stage from water-stage recorder, 0.27 foot several days in August and September 

(discharge, 0.01 second-foot).

1917-1920: Maximum stage recorded, 1.37 feet March 10, 1918 (discharge, 6.8 

second-feet); minimum stage and discharge in 1919 and 1920.

DIVERSIONS. About a mile above the station a tunnel has been driven into the

stream bed and a 4-inch pipe carries the water past the gage. See page 123 for

. record of this diversion. 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 permanent. Rating curve fairly well defined. 

Operation of water-stage recorder satisfactory throughout the year. Daily discharge ascertained by applying to the rating table mean daily gage height determined by inspecting gage-height graph, except March 22, 1920, when bi-hourly 

discharge was averaged. Records good.

The following discharge measurement was made by volumetric method by C. W. 

Sopp: 

July 12, 1919: Gage height, 0.28 foot; discharge, 0.01 second-foot.

ARROYO SECO NEAR PASADENA, CALIF.

LOCATION. Near south line of sec. 30, T. 2 N., R. 12 W. (unsurveyed), just

trail crossing at forest ranger's station in Angeles National Forest, 1£ miles abov-^ 

mouth of Millard Canyon, 3 miles above Devil's Gate, and 5J miles northwest 

of Pasadena, Los Angeles County.

DRAINAGE AREA. 16.4 square miles (measured on topographic map).

RECORDS AVAILABLE. December 1, 1910, to September 30, 1920.

GAGE. Gurley graph water-stage recorder in concrete well and house, installed 

September 30,1916, on right bank just upstream from original staff gage. Origins! 

datum was not maintained.

DISCHARGE MEASUREMENTS. Made from cable 130 feet below gage or by wading.

CHANNEL AND CONTROL. Bed consists of solid rock, gravel, and boulders. A concrete dam, extending to bedrock, was built across channel 15 feet below gageThere is a notch in the crest 2 feet wide and 1 foot deep. In July, 1919, a concrete intake box was built from gage house down to control.

EXTREMES OF DISCHARGE. Maximum stage during year ending September 30, 1919, 

from water-stage recorder, 2.72 feet at 8 a. m. February 11 (discharge, 92 secondfeet); minimum stage, from water-stage recorder, 0.72 foot September 15 to 17 

(discharge, about 0.1 second-foot).

Maximum stage during year ending September 30, 1920, from water-stage recorder, 3.74 feet at 1.30 a. m. March 2 (discharge, 670 second-feet); minimum stage, 

from water-stage recorder, 0.72 foot August 20 to 23 (discharge, 0.04 second-foot).

1910-1920: Maximum stage recorded, 12.5 feet February 20, 1914 (discharge, 

from extension of rating curve, 5,630 second-feet); minimum discharge, August 

20 to 23, 1920.
LOS ANGELES ETVEK BASIN. 127

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation affected by changes made at control May 12 

and July 31, 1919; apparently permanent since the latter date. The several 

rating curves are well defined except for period June 22* to September 30, 1919, 

when discharge was interpolated between measurements, and read from curves 

covering short periods of time. Daily discharge was ascertained by applying 

to the rating table mean daily gage height determined by inspection of recorder 

graph. Hourly discharge was averaged for February 22, March 1, 2, and 22, 

1920. Water-stage recorder was not in operation for certain periods (see footnote 

to table of daily discharge); discharge interpolated or estimated by comparison 

with record of flow on Tujunga Creek. Records good.

SURFACE WATER SUPPLY, 1919 AND 1920, PART XI. 131

CARPINTERIA CHEEK BASIN. 

GOBERNADOR CREEK NEAR CARPINTERIA, CALIF.

LOCATION. In SW. \ SW. \ sec. 14, T. 4 N., R. 25 W., 1,000 feet below junction of 

Eldorado and Steer creeks and 3J miles northeast of Carpinteria, Santa Barbara 

County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. June 24, 1916, to September 30, 1920 (not complete).

GAGE. Vertical staff in two sections on left bank; read by K. C. Lillingston. A temporary gage was used June 24 to September 11,1916.

DISCHARGE MEASUREMENTS. Made from cable 150 feet below gage or by wading.

CHANNEL AND CONTROL Small boulders and gravel; shifts. Banks high, clean, and 

not subject to overflow.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, from high-water mark, 2.4 feet between November 17 and 19 (discharge, 

88 second-feet); minimum stage, 0.98 foot August 25, 1919 (discharge, 0.4 secondfoot).

Maximum stage for the year ending September 30, 1920, not known; stream was 

practically dry part of August and September.

1916-1920: Maximum stage recorded, 3.5 feet February 21,1917 (discharge, 200 

second-feet); stream practically dry August and September, 1920.

DIVERSIONS. None above. The Gobernador Water Co. diverts water at a submerged 

dam 1 mile below station.

REGULATION. None.

ACCURACY. Stage-discharge relation changed slightly. Gage read to hundredths 

about once a week. Daily discharge ascertained by applying gage height to rating 

table. Record for 1919 fair, but as only one measurement was made in 1920 that 

record must be considered poor. Monthly discharge not computed.

COOPERATION. Gage-height record furnished by K. C. Lillingston.

ALAMEDA CREEK BASIN. 143

ALAMEDA CREEK NEAR NILES, CALIF.

LOCATION. In Niles Canyon, one-eighth mile below Southern Pacific Co.'s first 

bridge above Niles, one-fourth of a mile above highway bridge, and 1J miles 

northeast of Niles, Alameda County.

DRAINAGE AREA. 633 square miles (measured on topographic map by State Water 

Commission).

RECORDS AVAILABLE. October 1, 1916, to September 30, 1920.

GAGE. Gurley electric printing water-stage recorder on right bank at highway water 

tank 1,800 feet above highway bridge. Previous to January 15, 1918, gage was a 

Spring Valley Water Co. type water-stage recorder.

DISCHARGE MEASUREMENTS. Made from suspension footbridge 800 feet below gage 

or by wading.

CHANNEL AND CONTROL. Gravel; not permanent. Banks are high; channel straight 

from gage to some distance below suspension bridge. Control at gage solid rock 

and boulders.

DIVERSIONS. Spring Valley Water Co. obtains water from the gravels at lower end of 

Livermore Valley, above station. See Spring Valley Water Co.'s aqueduct near 

Sunolglen. Water, for irrigation purposes, is diverted on right bank at Niles dam 

about 1 mile above station.

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

period of natural low-water flow.

ACCURACY. Stage-discharge relation not permanent. Frequent discharge measurements, covering entire range, of stage, were obtained during 1919. Rating curves 

are well defined. Daily discharge determined by averaging the results obtained 

by applying mean gage height for short period to rating table. Special care was 

exercised in making discharge measurements, maintaining water-stage recorder 

and other equipment, and compiling record. Record excellent.

COOPERATION. Data for 1919 collected and compiled under personal supervision of 

Paul Bailey, engineer, and furnished for publication by State Water Commission 

of California.

146 SURFACE WATER SUPPLY, 1919 AND 1920, PART XI. 

ALAMEDA CREEK NEAR DECOTO, CALIF.

LOCATION. At Beard tract, 400 feet above mouth of Dry Creek, below Crandall Slough, 

and 1 mile southwest of Decoto, Alameda County; 6| mil«s below station in Niles 

Canyon near Niles.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. October 1, 1916, to September 30, 1919, when the station was 

discontinued.

GAGE. Gurley electric printing water-stage recorder on left bank, 400 feet above 

mouth of Dry Creek. Previous to January 15 gage was a Spring Valley Water Co. 

type water-stage recorder.

DISCHARGE MEASUREMENTS. Made from suspension footbridge just above gage or 

by wading. Measurements are also made at Rodriques Bridge, 1| miles downstream, and results reduced by discharge of Dry Creek to give flow at gage.

CHANNEL AND CONTROL. Composed of gravel, sand, and silt; not permanent. Banks 

high and steep, and have been cleared in vicinity of station. At flood stage some 

water leaves channel through Crandall Slough, 1$ miles above gage.

DIVERSIONS. See Alameda Creek near Niles. In addition, water is pumped from 

creek at four points above station for irrigation purposes. Some water is returned 

to creek at three gravel-washing plants between mouth of canyon and station.

REGULATION. See Alameda Creek near Niles.

ACCURACY. Stage-discharge relation not permanent. Frequent discharge measurements were obtained covering entire range of stage. Several well-defined rating 

curves were used during year. Daily discharge determined by averaging the 

results obtained by applying mean gage height for short period to rating table. 

Special care was exercised in making discharge measurements, maintaining waterstage recorder and other equipment, and compiling record. Records excellent.

COOPERATION. Data collected and compiled under personal supervision of Paul 

Bailey, engineer, and furnished for publication by State Water Commission of 

California.

curve. The first gage was replaced March 17, 1914, by a vertical staff in two 

sections, 7 feet downstream from the original one, on the same bank and at the 

same datum. The recorder was installed September 15, 1913, in the same pool

TT7LARE LAKE BASIN. 

TTJLARE LAKE IN KINGS COTJNTY, CALIF.

LOCATION. At headgate at corner of north-south and east-west levees on G.<Albert 

Smith ranch, at quarter corner between sees. 8 and 17, T. 21 S., R. 20 E., 5 miles 

southwest of Stratford.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. March 15, 1906, to September 30, 1920 (incomplete). All 

published records give actual depth of water on the lowest point of the lake bed.

GAGE. Vertical staff in three sections, two fastened to the headgate, high-water 

section at junction of Smith's levee and the Empire levee 2 miles north; read by 

Ernest Coonradt. Gage readings reduced to depth of water from the following 

data. Elevation of bottom of lake, 179.1 feet above mean sea level; elevation of 

zero of gage, 176.4 feet.

During 1906 and a part of 1907 the readings were made from a gage near the 

entrance of Kings River near Lemoore, at the middle of sec. 4, T. 21 S., R. 20 E.; 

zero of that gage was at elevation 175.1 feet. May 11, 1907, a staff gage was set 

near Corcoran, with its datum at the same elevation, and was used until July 30, 

1909. July 28, 1910, a vertical staff was installed on the section line just south of 

the corner of sees. 27, 28, 33, and 34, T. 20 S., R. 20 E., about 10 miles south of Lemoore, near Stratford post office; elevation of the zero of this gage, 171.0 feet. 

August 20, 1913, a vertical staff in four sections was installed in main north and 

south waterway, 4 to 6 miles southeast of Stratford; its zero was also at elevation 

171.0 feet. Sections No. 1 and No. 2 were 1 mile south of gage used in 1910 in 

sec. 3, T. 21 S., R. 20 E.; No. 3 was in sec. 10; and No. 4 was in sec. 15, 1 mile 

and 2 miles, respectively, south of sections Nos. 1 and 2.

Present gage was installed May 15, 1914, on account of the rebuilding of the 

levees. The high-water section on the levee near by, added July 16, 1916, was 

used up to October 28, 1916, after which the present high-water section has been 

in use.
162 SURFACE WATER SUPPLY, 1919 AND 1920, PART XI.

EXTREMES OF STAGE. Maximum depth recorded during years ending September 

30, 1919 and 1920, 2.3 feet October 1, 1919; lake empty April 30, 1919, to September 30, 1920.

1906-1920: Maximum depth, 14.0 feet June 21, 1907; the lake was empty a 

period in 1906, the last part of October to the last part of December, 1914, the last 

part of November, 1916, and from April 30, 1919, to September 30, 1920.

The lake is roughly rectangular in shape, and its greatest length is from northwest to 

southeast. In November, 1907, when its margin was carefully determined, the lake 

had a maximum depth of 12.4 feet, an average length of 20 miles, a width of 13.5 miles, 

and an area of about 274 square miles; the water's edge was 3 miles from the town of. 

Corcoran, and the water surface about 12 feet below.

The lake bed resembles a flat saucer. The flat, level area in the bottom is about 

180 feet above mean sea level and covers about 55 square miles. The lowest poin t 

on the crest of the delta ridge to the .north is about 27 feet higher than the bottom 

of the lake. Natural outflow will not occur, therefore, until the lake has a maximum 

depth of nearly 30 feet and an area of nearly 1,000 square miles.

TULAEE LAKE BASIN. 169

SOUTH FORE OF TITLE RIVER NEAR PORTERVILLE, CALIF.

LOCATION. Opposite Indian school in Tule Indian Reservation, 2 miles below 

mouth of Rocky Creek, 7 miles southeast of Success, 8 miles above jtlnction with 

Tule River, and 14 miles southeast of Porterville, Tulare County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. October 10, 1910, to September 30, 1920.

GAGE. Vertical staff on right bank 30 feet above pump house, July 18,1916, to June 

30,1920; read by employees of Indian Service. Original gage was 100 feet above 

pump house and at a different datum. A temporary gage located 350 feet below 

pump house and at an independent datum was used July 1 to September 30,1920.

DISCHARGE MEASUREMENTS. Made from cable 1£ miles below gage or by wading.

CHANNEL AND CONTROL. Rough; boulders and gravel; shifts slightly during high 

water. Banks high and not subject to overflow.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 3.0 feet night of March 2 (discharge, 300 second-feet); minimum stage 

recorded, 0.7 foot August 24 to September 17 (discharge, 1.8 second-feet).

Maximum stage recorded during year ending September 30, 1920, 4.8 feet at 

6 p. m. April 15 (discharge, 1,030 second-feet); minimum stage recorded, 0.9 

foot October 21-25 and 1.88 feet (temporary gage) August 7-14 (discharge, 4 

second-feet).

1910-1920: Maximum stage recorded, 8 feet at 8 a. m. January 26, 1914 

(discharge, determined from extension of rating curve, about 2,750 second-feet); 

minimum stage recorded, 0.48 foot August 8-24 and September 14, 1918 (discharge, 

0.7 second-foot).

DIVERSIONS. Several small irrigation ditches, having a total capacity of about 12 

second-feet, divert water above the station.

REGULATION. None.

ACCURACY. Stage-discharge relation changed November 24, 1918. Rating curves 

well defined between 3 second-feet and 200 second-feet and extended above. 

Curve for temporary gage fairly well defined. Gage read to half-tenths once 

daily but gage heights are unreliable December 8-9, 1919, and February 20-28, 

1920. Daily discharge ascertained by applying gage height to rating table, 

except December 8-9, 1919, and February 20-28, 1920, when it was estimated 

from flow of Tule River. Records good to June 30, 1920, and fair July 1 to 

September 30, 1920.

COOPERATION. Gage-height record furnished by United States Indian Service.

KAWEAH RIVER NEAR THREE RIVERS, CALIF. '

 LOCATION. In SE. i sec. 27, T. 17 S., R. 28 E., at J. O. Carter's ranch l\ miles southwest of Three Rivers, Tulare County. South Fork enters three-fourths of a 

mile above station and North Fork 3 miles above.

DRAINAGE AREA. 520 square miles.

RECORDS AVAILABLE. April 29, 1903, to September 30, 1920.

GAGE. Vertical and inclined staff in four sections on left bank a few feet above cable 

and one-fourth of a mile back of observer's house; read by J. H. Vickroy. The 

original gage was installed by the United States Geological Survey at same location and datum. On December 5, 1912, the Weather Bureau gage was installed 

and for about two years the two gages were read interchangeably. October 19, 

1914, the Geological Survey repaired the upper section of the Weather Bureau 

gage and used this gage to October 27, 1917, when the entire gage was rebuilt.

DISCHARGE MEASUREMENTS. Made from cable at gage or by wading.

CHANNEL AND CONTROL. Gravel and boulders; fairly permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 8.1 feet at 7.40 a. m. May 29 (discharge, 2,830 second-feet); minimum stage, 4.50 feet October 25, 26, September 3 to 5,10 to 16, and 20 (discharge, 

26 second-feet).

Maximum stage recorded during year ending September 30, 1920, 9.8 feet at 

7.30 a.m. April 16 (discharge, 5,850 second-feet); minimum stage, 4.50 feet October 17 to 19 (discharge, 26- second-feet).

1903-1920: Maximum stage recorded, 13.5 feet at 11 a. m. January 17, 1916 

(discharge, from extension of rating curve, about 14,700 second-feet); minimum 

discharge, 26 second-feet, in years ending September 30, 1919 and 1920.
172 SURFACE WATER SUPPLY, 1919 AND 1920, PART XI.

DIVERSIONS. Several canals divert water above McKay Point and below Three 

Rivers. Capacity of these canals is about 135 second-feet with an annual diversion of about 35,000 acre-feet.

REGULATION. Power is developed on the Middle and East forks, but effect on discharge at the gaging station is thought to be small.

ACCURACY. Stage-discharge relation not changed during toe period. Rating curve 

well denned between 40 and 4,000 second-feet. Gag£ read to half-tenths twice 

daily but it is believed that the observer estimated gage heights frequently 

during high water. Daily discharge ascertained by applying mean daily gage 

height to rating table. Records good during low water but are questionable 

during high water owing to unreliability of observer.

KAWEAH RIVER AT McKAY POINT , NEAR LEMON QOVE, CALIF.

LOCATION. On section line between sees. 3 and 4, T. 17 S., R. 27 E., at diversion 

dam at McKay Point, 1 mile west of Lemon Cove, Tulare County, and 9 miles 

below United States Geological Survey gaging station near Three Rivers.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. October 1, 1918, to September 30, 1920.

GAGE. Water-stage recorder on left bank a short distance above dam.

DISCHARGE MEASUREMENTS. Made by wading on crest of dam, or from cable 1 mile 

upstream at high water.

CHANNEL AND CONTROL. Control formed by two broad crested weirs set at an angle 

of 90 degrees with the point upstream. The left weir is 117 feet long and the 

right weir is 113 feet long. The left weir discharges into Kaweah River and the 

right weir into St. Johns River. Both weirs are level for a distance of 12 feet 

back from overfall. Height of overfall is 15 inches, the water falling on a sloping 

concrete apron.

DIVERSION. Several irrigating ditches divert water between the gaging station near 

Three Rivers and McKay Point. Proceeding downstream they are as follows: 

Meyers ditch, diverts 2 second-feet half time for 10 months. 

Marks ditch, diverts 2 second-feet half time for 10 months. 

Lemon Cove ditch, diverts 7 second-feet continuously for 9 months. 

Merryman ditch, diverts 9 second-feet continuously for 9 months. 

Wutchumna ditch, diverts 10 per cent of the flow up to 1,000 second-feet with 

no stated rights above that stage, continuously except during November. During 

May and June it may divert as much as 115 second-feet.

The total annual diversion of these ditches is between 30,000 and 35,000 acrefeet. The maximum capacity of all ditches is about 135 second-feet.

ACCURACY. Stage-discharge relation changes when flashboards are placed on weirs 

to divide water. Rating curves for each condition well defined up to 1,700 

second-feet and fairly well defined above. Water-stage recorder set to record 

natural scale. Daily discharge ascertained by applying mean daily gage height 

to rating table.

COOPERATION. Daily-discharge record furnished by H. H. Holley, consulting 

engineer, Visalia, Calif.

NORTH FORE OF KAWEAH RIVER AT KAWEAH, CALIF.

LOCATION. In SW. i sec. 2, T. 17 S., R. 28 E., at highway bridge in Sequoia National 

Forest, half a mile north of Kaweah, Tulare County, and 2 miles above junction 

with Kaweah Eiver. Manikin Creek enters one-fourth mile below and Sheep 

Creek 2£ miles above gage.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. October 12, 1910, to September 30, 1920.

GAGE. Staff gage in two sections on right bank; low-water section is inclined and 

fastened to abutment of bridge; upper section is vertical and fastened to sycamore 

tree 20 feet below bridge. Previous to flood of January, 1914, gage was vertical 

staff fastened to right abutment. Original datum has been maintained. Gage 

read by J. T. Weckert and T. T. Gross.

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

CHANNEL AND CONTROL. Solid rock and sand; fairly permanent. One channel at 

all stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 2.5 feet at 11 a. m. February 11 (discharge, 360 second-feet); minimum 

stage, 0.03 foot at 5 p. m. September 2 (discharge, 2.0 second-feet).

Maximum stage recorded during year ending September 30, 1920, 4.22 feet at 

9 a. m. April 17 (discharge, 1,500 second-feet); minimum stage, 0.20 foot at 3.30 

p. m. August 20 (discharge, 1.5 second-feet).

1910-1920: Maximum stage recorded, 10.2 feet at 7 p. m. January 25, 1914 

(discharge, from extension of rating curve, about 7, 400 second-feet); minimum 

discharge, 0.8 second-feet, August 27, 1913.

DIVERSIONS. About 20 second-feet is diverted by several small ditches for irrigation 

above the station.
TULARE LAKE BASIN. 177

REGULATION. None.

ACCURACY. Stage-discharge relation changed October 2, 1918, and April 17, 1920. 

Rating curves used to April 17, 1920, fairly well defined between 2 and 400 secondfeet and extended above; curve used April 18 to September 30, 1920, fairly well 

defined between 25 and 400 second-feet. Gage read to hundredths once daily. 

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

for the year ending September, 1919, are good except at low stages. Owing to 

lack of sufficient discharge measurements the records for the year ending September 30, 1920, are fair, except those at low stages, which are probably poor.

stopped May 8 to June 12, October 28 to November 9, 1919, and December 27, 

1919, to January 4, 1920. Mean daily gage height determined by averaging readings printed every fifteen minutes by the water-stage recorder. Daily discharge 

ascertained by applying mean daily gage height to rating table. Discharge for 

periods of no record estimated by comparison with record for Kings River near 

Sanger. Records excellent except for estimated periods, for which they are fair.

SAN JOAQUIN RIVEB BASIN. 189

STEVENSON CREEK AT SHAVER, CALIF.

LOCATION. Three-fourths of a mile below Shaver Lake dam and three-fourths of a 

mile west of Shaver, Fresno County.

DRAINAGE AREA. 30.2 square miles (measured on topographic map).

RECORDS AVAILABLE. October 1,1916, to September 30,1920.

GAGE. Lietz water-stage recorder on right bank about 50 feet above weir. Zero of 

gage set at elevation of crest of low-water weir.

DISCHARGE MEASUREMENTS. Made from cable half a mile above gage or by wading.

CHANNEL AND CONTROL. Boulders and bedrock. Control is a compound weir consisting of a 64-foot rectangular sharp-crested weir with end contractions practically 

suppressed and in the middle of this weir an 8-foot rectangular, sharp-crested 

weir, 1 foot deep, for low flow. Weir is very satisfactorily installed and leakage 

is very small.

ICE. Considerable ice forms at the station, but it is not likely that the stage-discharge 

relation is ever affected by it.

DIVERSIONS. Fresno Flume & Lumber Co.'s two flumes divert water at Shaver Lake 

dam. This water was used for floating lumber to Clovis and then used for irrigation during 1918 and part of 1919. Two waste gates in the lower flume return the 

water to the creek above the station. It is not know^ when these waste gates were 

open and so the total flow from the drainage area is indeterminate.

REGULATION. During dry season entire flow is regulated at Shaver Lake dam. Capacity of Shaver Lake reservoir is reported as 4,880 acre-feet.

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

800 second-feet and is an extension above. Daily discharge ascertained by applying mean daily gage height to rating table. Hourly discharge was averaged for 

days when there was much change in stage.

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

through H. W. Dennis, construction engineer.

No discharge measurements were made during the years 1918 to 1920.

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

Sept. 30, 1918-1920.

SURFACE WATER SUPPLY, 1919 AND 1920, PART XI. 199

MEECED EIVEE BASIN. 

MERCED RIVER AT HAPPY ISLES BRIDGE, NEAR YOSEMITE, CALIF.

LOCATION. At Happy Isles Bridge, below power house 1^ miles southeast of Yosemite, 

Mariposa County.

DRAINAGE AREA. 181 square miles (measured on topographic maps).

RECORDS AVAILABLE. August 23,1915, to September 30,1920.

'xAGE. Friez water-stage recorder on right bank about 20 feet below bridge. Previous to November 2, 1916, the gage was a staff fastened to downstream side of 

large boulder which is used for the right abutment of the bridge.

DISCHARGE MEASUREMENTS. Made from Clark Bridge about half a mile below gage 

or by wading.

CHANNEL AND CONTROL. Boulders; practically permanent. Banks high; not subject 

to overflow.

EXTREMES OF DISCHARGE. Maximum stage during year ending September 30, 1919, 

from water-stage recorder, 7.10 feet at 10 p. m. May 28 (discharge, 3,800 secondfeet); minimum stage, from water-stage recorder, 0.42 foot September 25 to 27 

(discharge, 7 second-feet).

Maximum stage during year ending September 30, 1920, from water-stage recorder, 6.10 feet at 11 p. m. May 19 (discharge, 2,720 second-feet); minimum stage, 

from water-stage recorder, 0.43 foot at 10 a. m. November 25 (discharge, 7.5 secondfeet). *

1915-1920: Maximum stage recorded in 1919 (discharge, 3,800 second-feet); 

minimum stage, from water-stage recorder, 0.13 foot at 11 a. m. January 9, 1918 

(discharge, 2.1 second-feet).

"CE. Stage-discharge relation not affected by ice.

DIVERSIONS. None.

REGULATION. Power plant above station; water returned to the river just above 

gage. Plant not in regular operation during the period; abandoned during 1920.

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

denned. Mean daily gage height determined by inspecting recorder graph. 

Daily discharge ascertained by applying mean daily gage height to rating 

table. For periods of no record, discharge estimated by comparison with the 

records for Merced River at Pohono Bridge, Tenaya Creek, and South Fork of 

Merced River at Wawona (see footnote to daily-discharge table). Records excellent except for periods when recorder did not work properly.

'COOPERATION. Gage-height record furnished by officials of Yosemite National Park.

Discharge measurements of Merced River at Happy Isles Bridge, near Yosemite, Calif, 

during the year ending Sept. 30, 1919.

upstream from Merced Falls.

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

RECORDS AVAILABLE. November 28, 1915, to September 30, 1920.

GAGE. Vertical staff in four sections bolted to solid rock ledge on right bank 250 

feet above old dam; read by Heigel, Johnston, and Stewart.

DISCHARGE MEASUREMENTS. Made from cable half a mile above gage or by wadin?.

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

is old concrete dam. Banks high, clean, and not likely to be overflowed. Part 

of dam was blasted out February 1, 1918.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30,1919,14.8 feet at 7 a. m. May 29 (discharge, 8,540 second-feet); minimum stage, 

4.0 feet September 21, 22, and 26 (discharge, 14 second-feet).

Maximum stage recorded during year ending September 30, 1920, 15.0 feet at 

5 p. m. April 15 (discharge, 8,950 second-feet); minimum stage, 4.0 feet September 24 and 27 (discharge, 14 second-feet).

effect of their operation is believed to be slight except during low water.

ACCURACY. Stage-discharge relation practically permanent. Rating curve we1 ! 

denned above 30 second-feet. Gage read to half-tenths twice daily. Daily 

discharge ascertained by applying mean daily gage height to rating table. Records excellent except those for low water when operation of power plants causes 

diurnal fluctuation.

218 SURFACE WATER SUPPLY, 1919 AND 1920, PART XI.

TUOLUMNE RIVER ABOVE LA GRANGE DAM, NEAR LA GRANGE, CALIF.

LOCATION. In NE. £ sec. 3, T. 3 S., R. 14 E., 3£ 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, 1920.

GAGE. Gurley printing water-stage recorder on left bank.

DISCHARGE MEASUREMENTS. 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 ending September 30, 1919, 

from water-stage recorder, 18.10 feet at 9 a. m. May 29 (discharge, 15,600 secondfeet.) Minimum stage, from water-stage recorder, 1.50 feet from 6 to 9 a. m. 

September 23 (discharge, 17 second-feet). «

Maximum stage during year ending September 30, 1920, from water-stage 

recorder, 18.05 feet at 4 a. m. April 16 (discharge, 15,500 second-feet); minimum 

stage, from water-stage recorder, 1.73 feet from 4 p. m. November 20 to 8 a. m. 

November 21 (discharge, 27 second-feet).

1916-1920: Maximum stage recorded, 27.58 feet at 5.15 p. m. February 21, 1917 

(discharge, 36,500 second-feet); minimum stage, 1.06 feet October 30, 31, November 4 and 5, 1917 (discharge, 5 second-feet).

DIVERSIONS. Sierra and San Francisco Power Co.'s canal heads 9J miles above the 

station and returns its water half a mile above the bridge at La Grange, except 

during irrigation seasons in 1919 and 1920, when the water was not used for power 

but was returned to river above La Grange dam for use by Waterford Irrigation 

District. There is also a diversion from South Fork of Tuolumne River at Harden 

ranch for use in vicinity of Groveland.

REGULATION. None.

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

Operation of water-stage recorder satisfactory. Mean daily gage height determined by averaging gage heights printed every 15 minutes by the water-stage 

recorder. Daily discharge ascertained by applying mean daily gage height to 

rating table, except February 10 and 11, 1919, March 1 and 21, 1920, when 

hourly discharge was averaged. Records excellent.

CHERRY CREEK NEAR HETCH HETCHY, CALIFS

LOCATION. In SW. \ see. 28, T. 2 N., R. 19 E., in Stanislaus National Forest, at 

abandoned sawmill camp, 3 miles by trail from Lake Eleanor, 7$ miles northwest 

of Hetch Hetehy, and 13 miles north of Sequoia, Tuolumne County.

DRAINAGE AREA. 114 square miles 5 (above dam site in sec. 5, T. 1 N., R. 19 E.).

RECORDS AVAILABLE. April 1, 1910, to September 30, 1920, and May 26 to October 

15, 1901, at Eleanor trail crossing.

GAGE. Gurley printing water-stage recorder on right bank 800 feet above site of 

old suspension bridge. Original gage was a Lietz graph water-stage recorder at 

the bridge. It was moved upstream to present site (new datum) October 22, 

1913; and replaced by the present gage (same datum) November 30, 1914.

DISCHARGE MEASUREMENTS. Made from cable 800 feet below gage or by wading.

CHANNEL AND CONTROL. Bed consists of fine gravel and sand which shifts slightly. 

Control is a solid rock dike except at right bank, where it is gravel and small 

boulders. Channel is straight above and curved to right below. Left bank is 

high; right bank fairly high and probably not subject to overflow. Zero flow, 

gage height 0.4 foot.

EXTREMES OF DISCHARGE. Maximum stage during year ending September 30, 1919, 

from water-stage recorder, 8.14 feet at 10.30 p. m. May 28 (discharge, from extension of rating curve, about 3,550 second-feet); minimum stage, from water-stage 

recorder, 0.68 foot from noon September 26 to 7 a. m. September 28 (discharge, 

0.3 second-foot).

< Formerly published as "Cherry Creek near Sequoia, Calif."

6 Freeman, John E., The Hetch Hetehy water supply for San Francisco, p. 24,1912.
TTJOLTJMNE RIVER BASIN. 225

Maximum stage during year ending September 30, 1920, from water-stage 

recorder, 8.10 feet at 9 p. m. May 19 (discharge from extension of rating curve, 

3,550 second-feet); minimum stage, from water-stage recorder, 0.83 foot at 1 p. m. 

October 23 (discharge, 1.1 second-feet).

1910-1920: Maximum mean daily discharge, 7,000 second-feet January 31, 1911 

(maximum stage unknown); minimum stage, no flow September 6 to 12, 1910.

ICE. Stream freezes over at gage but not at control. Stage-discharge relation probably not affected by ice.

DIVERSIONS . None.

REGULATION. None.

ACCURACY. Stage-discharge relation permanent. Rating curve well defined between 10 and 3,000 second-feet. Operation of water-stage recorder satisfactory 

throughout the year. Daily discharge ascertained by applying to rating table 

mean daily gage height determined by averaging the readings printed every 15 

minutes by the water-stage recorder, except October 5, 1918, September 29, 

October 24, and December 11, 1919, when hourly discharge was averaged. 

Records excellent except those for extreme low water, which are good.

5,000 second-feet); minimum stage, dry September 8 to 14, 1910.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. None.

REGULATION. Flow completely regulated by operation of gates in Eleanor dam.

ACCURACY. Stage-discharge relation permanent. Rating curve well defined. Operation of water-stage recorder satisfactory throughout the period. Daily discharge 

ascertained by applying to rating table mean daily gage height determined by 

inspecting recorder graph, except days of large diurnal fluctuation, when hourly 

discharge was averaged. Records excellent.

Meadows, Mariposa County. Middle Fork enters 2J miles above the station.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. September 13, 1910, to September 30, 1920 (records fragmentary before September 30, 1916).

GAGE. Stevens continuous water-stage recorder installed November 4, 1916, on 

right bank 600 feet above trail bridge, at same location and datum as inclined 

staff gage installed May 19, 1914. Previous to this date gage was a vertical staff 

on middle pier of bridge at downstream end and at same datum as present gage.

DISCHARGE MEASUREMENTS. Made from cable half a mile above gage or by wading.

CHANNEL AND CONTROL. Boulders and gravel; very rough; practically permanent.

EXTREMES OF DISCHARGE. Maximum stage during year ending September 30, 1919, 

from water-stage recorder, 6.90 feet at 11 p. m. May 28 (discharge, 1,860 secondfeet); minimum stage from water-stage recorder, 2.27 feet at 7 p. m. August 10 

(discharge, 3.0 second-feet).

Maximum stage recorded during year ending September 30, 1920, 6.41 feet at 

3 a. m. May 20 (discharge, 1,270 second-feet); minimum stage, 2.38 feet October 

22 to 23 (discharge, 5 second-feet).

1910-1920: Maximum stage recorded, between 8 and 10 feet January 25, 1914. 

A camper at the bridge said that on that date the water touched the under 

stringers of the footbridge (discharge not determined); minimum discharge, 3 

second-feet, September 15, 1913, and August 10, 1919.

DIVERSIONS. Water is diverted at Harden ranch, 7 miles above mouth, for use in

TUOLUMNE RIVER BASIN. 231

REGULATION. A small amount of storage is developed at Harden ranch.

ACCURACY. Stage-discharge relation has remained practically permanent. Rating 

curve well defined. Mean daily gage height determined by inspecting recorder 

graph. Daily discharge ascertained by applying mean daily gage height to 

rating table except February 9 to 11, 26, May 28, 29, December 11, 1919, March 

1 and April 15, 1920, when hourly discharge was averaged. Records good.

SIERRA & SAN FRANCISCO POWER CQ.'S CANAL NEAR LA GRANGE, CALIF. 

"JOCATION. In SW. \ sec. 16, T. 3 S., R. 14 E., at short flume opposite La Grange 

dam, just above waste gate, three-fourths of a mile above power house, 1J miles 

northeast of La Grange, Stanislaus County, and 13f miles below intake on Tuolumne River.

RECORDS AVAILABLE. 1908 to September 30, 1920 (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. 

"^XTREMES OP DISCHARGE. 1908-1920: Maximum discharge recorded, 70 secondfeet during part of season 1919-1920.

ACCURACY. Stage-discharge relation changed February 10, 1919, and during fall of

1919 when canal was dry. Rating curves well denned. 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 

'""uolumne River at Indian Bar, in SW. J sec. 6, T. 2 S., R. 15 E., 15 miles above the 

'own of La Grange. This canal was built in the early days to supply water for 

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

Grange mining ditch." Having been thoroughly repaired, it is used as a supply 

<~anal for the hydroelectric plant which was installed in 1907. The power house is 

< " ! the left bank of the river about a half mile above La Grange and is below La Grange 

'am. Water diverted by canal is returned to river at power house. During the 

frrigating seasons of 1919 and 1920 water was returned to the river above La Grange 

j'am and sold to the Waterford Irrigation District.

238 SURFACE WATER SUPPLY, 1919 AND 1920, PART XI.

MODESTO CANAL NEAR LA GRANGE, CALIF.

LOCATION. In SE. J sec. 17, T. 3 S., R. 14 E., below waste gates, 500 feet below 

intake at La Grange dam on Tuolumne River, and 1J miles northeast of La Grange, 

Stanislaus County. Canal is on right bank of river.

RECORDS AVAILABLE. April 26, 1903, to September 30, 1920.

GAGE. Vertical staff in concrete well on left bank. March 27, 1920, gage was moved 

50 feet downstream when canal was improved. Gage read by J. H. Morton.

DISCHARGE MEASUREMENTS. Made from footbridge 500 feet below gage.

CHANNEL AND CONTROL. Canal is concrete lined; control is slope and cross-section 

below gage. For the last few years timber flumes that formed the canal a mile 

or more below the station have been gradually replaced by fills with concrete 

lining. The cross-section has been increased thereby increasing capacity of 

canal.

EXTREMES OP DISCHARGE. 1903-1920: Maximum discharge, 1,340 second-feet, in 

April and May, 1920.

ACCURACY. Stage-discharge relation changed when canal was improved in 1920. 

Rating curves well denned. Gage read to hundredths twice daily and changes 

in gates noted. Daily discharge ascertained by applying mean daily gage height 

to rating table or by averaging results obtained by applying gage height for parts 

of day to rating table. Records excellent.

COOPERATION. Gage-height record and results of some discharge measurements 

furnished by Modesto Irrigation District. The water is used to irrigate abo^t 

59,000 acres of land in the Modesto Irrigation District.

NOTE. Natural run-off in acre-feet determined by deducting the flow of Philadelphia ditch from the 

observed flow at Sand Bar Flat and then correcting for storage in Rslief reservoir.

STANISLAUS RIVER NEAR KNIGHTS FERRY, CALIF.

LOCATION. In SW. i sec. 1, T. 1 S., R. 12 E., 300 feet above old Tulloch dam, 2 

miles above Goodwin dam, and 6 miles above Knights Ferry, Stanislaus County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. December 18, 1915, to September 30, 1920. Also at Knights 

Ferry, May 19, 1903, to April 30, 1916.

GAGE. Stevens continuous water-stage recorder on right bank in reinforced concrete 

well and house, installed July 28, 1917, replacing a Gurley printing recorder.

DISCHARGE MEASUREMENTS. Made from cable 20 feet above gage or by wading.

CHANNEL AND CONTROL. Bed consists of solid rock and shifting sand. Channel 

straight for 250 feet above and 300 feet below; one channel at all stages. Control 

is Tulloch dam. Point of zero flow, gage height about 0.6 foot.

EXTREMES OF DISCHARGE. Maximum stage during year ending September 30, 1919, 

from water-stage recorder, 5.95 feet at 8 a. m. May 1 (discharge, 9,700 second-feet); 

minimum stage, from water-stage recorder, 1.02 feet at 8 a. m. September 24 (discharge, 60 second-feet).

Maximum stage recorded during year ending September 30, 1920, 5.70 feet at 

6.30 a. m. May 20 (discharge', 8,860 second-feet); minimum stage, 0.94 foot from 

1 to 7 p. m. November 25 (discharge, 39 second-feet).

1915-1920: Maximum stage recorded, 9.11 feet at 3.45 a. m. February 21, 1917 

(discharge, determined from revised extension of rating curve, 20,000 secondfeet); minimum stage occurred November 25, 1919.
STANISLAUS EIVER BASIN. 245

DIVERSIONS. Numerous ditches divert water for mining above the station. Water 

is also diverted from South Fork into the Tuolumne basin and from North Fork 

for use in the vicinity of Murphy and Angels (see Utica Gold Mining Co.'s canal 

near A very, page 249). The water 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 practically permanent. Rating curve well defined below 10,000 second-feet and extended above. Recorder not running during periods stated in footnote to daily-discharge table. Mean daily gage height 

determined by inspecting recorder graph. Daily discharge ascertained by applying mean daily gage height to rating table. Records excellent.

Co. 's canal and 5 miles northeast of Avery, Calaveras County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. July 14, 1914, to September 30, 1920.

GAGE. Vertical staff in two sections on right bank, read by James Hunter.

DISCHARGE MEASUREMENTS. Made from cable 35 feet below gage or by wading.

CHANNEL AND CONTROL. Large boulders and gravel; apparently permanent. One 

channel at all stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 6.0 feet May 7 (discharge, 2,150 second-feet); minimum stage, 0.90 foot 

September 21 to 30 (discharge, 23 second-feet).

Maximum stage recorded during year ending September 30, 1920, 5.7 feet May 

23 (discharge, 1,880 second-feet); minimum stage, 0.85 foot November 27 and 

29 (discharge, 20 second-feet).

1914-1920: Maximum stage recorded, 8.7 feet May 11, 1915 (discharge, 5,250 

second-feet); minimum discharge, 20 second-feet, November 27 and 29, 1919.

DIVERSION. Water is diverted from Beaver Creek into North Fork of Stanislaus River 

about half a mile above the station.

REGULATION. Flow regulated to some extent by reservoirs on the headwaters of this 

stream.

ACCURACY. Stage-discharge relation practically permanent. Rating curve well defined between 30 and 4,000 second-feet. Gage read to half-tenths once on alternate days. Daily discharge ascertained by applying gage height to rating 

table, and interpolated for days on which gage was not read. Records good; lowwater records subject to some uncertainty owing to^effect of regulation and lack of 

refinement in gage readings.

COOPERATION. Gage-height record furnished by Utica Gold Mining Co.

Discharge measurements of North Fork of Stanislaus River near Avery, Calif., during the

year ending Sept. SO, 1919.

SOUTH SAN JOAQTTIN CANAL NEAR KNIGHTS FERRY, CALIF.

LOCATION. At footbridge three-fourths of a mile below headgate at Goodwin dam 

on Stanislaus River, 4 miles above Knights Ferry, Stanislaus County.

RECORDS AVAILABLE. May 1, 1914, to September 30, 1920. Also miscellaneous 

measurements and rough estimates for 1913.

GAGE. Vertical staff in gage well on left bank installed March 12, 1915; original gage 

was inclined staff on right bank 100 feet below and probably at the same datum. 

Gage read by Craig, Dolling, and Hill.

DISCHARGE MEASUREMENTS. Made from footbridge at gage.

CHANNEL AND CONTROL. Canal has trapezoidal section and is concrete lined. 

Tunnels below gage lined with concrete between September 19, 1919, and February 7, 1920.

EXTREMES OP DISCHARGE. 1914-1920: Maximum discharge, 1,030 second-feet, June 

19 to 24, 1920; no flow several periods each year.

ACCURACY. Stage-discharge relation changed when canal was cleaned between 

January 18 and February 25, 1919, and February 7, 1920, when canal was improved. Old and new rating curves well denned. Gage read to hundredths 

twice daily. Daily discharge ascertained by applying mean daily gage height 

to rating table. Records excellent.

COOPERATION. Daily gage-height record furnished by South San Joaquin Irrigation 

District.

South San Joaquin canal is on the right bank of the river. The water is used for 

irrigation in the Oakdale and South San Joaquin irrigation districts.

left low-water channel; No. 2, vertical, post in left bank; No. 3, vertical, bolted 

to middle pier near downstream end; No. 4, vertical, bolted to left abutment 

near downstream end. Read by Frank Hodges.

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

CHANNEL AND CONTROL. Sand and gravel; somewhat shifting. Right bank is high 

and not subject to overflow; left bank is overflowed above stage 15 feet, for a 

distance of 200 feet.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 10.9 feet at 7.30 a. m. February 11 (discharge, 7,540 second-feet); minimum stage, 1.0 foot at 7.30 p. m. July 21 (discharge, 17 second-feet).

GOOSE LAKE BASIN. 

DREW CREEK RESERVOIR NEAR LAKEVIEW, OREG.

LOCATION. Dam is in sec. 5, T. 40 S., R. 18 E.; reservoir extends upstream 10 miles. 

RECORDS AVAILABLE. February 26, 1913, to September 30, 1920; occasional readings

until February 6, 1916; after that date readings practically every day. 

GAGE. Gage attached to upstream face of dam since 1915. Previous readings

obtained by measuring down from the floor of gate house. Gage heights refer to

a datum level with lowest contour of reservoir. Gage reader, James McShane. 

OUTLETS. A tunnel with sill at elevation 16.3 feet and a blowout pipe in center of

dam at bottom. 

EXTREMES OF CONTENTS. Maximum stage recorded during year ending September 30,

1919, 47.0 feet May 10 to 22 (contents, 33,100 acre-feet); minimum stage, 30.7

feet November 2 to December 31 (contents, 3,910 acre-feet). 

Maximum stage recorded during year ending September 30, 1920, 41.8 feet

May 12 to 15 (contents, 20,000 acre-feet); minimum stage, 21.3 feet September

30 (contents, 980 acre-feet). 

1913-1920: Maximum stage recorded, 53.4 feet April 18 to 20, 1914 (contents,

55,500 acre-feet). 

ACCURACY. Prior to 1914 the estimated monthly increase or decrease in storage is

subject to some error, as the readings of water stage were very rough, but the

error for the entire year is probably not great. Beginning in 1914 the results are

The following readings, at the end of each month, have been used in correcting the

DREW CHEEK NEAR LAKEyiEW, OREG.

i

LOCATION. In SE. J sec. 4, T. 40 S., R. 18 E., at highway bridge half a mile below 

mouth of Willow Creek, 1 mile below Drew Creek dam, and 18 miles southwest 

of Lakeview, Lake County.

DRAINAGE AREA. 211 square miles.

RECORDS AVAILABLE. January 16, 1909, to September 30, 1919. 9

GAGE. Friez water-stage recorder on right bank, 100 yards upstream from highway 

bridge, used since May 18, 1918; inspected by James McShane. Several other 

gages prior to that date; relation of datums uncertain.

DISCHARGE MEASUREMENTS. Made from wagon bridge or by wading.

CHANNEL AND CONTROL. Control about 150 feet below gage, of rock and apparently 

permanent; bed composed of gravel and sand; shifts slightly; drift and growth of 

aquatic plants collect on control occasionally, affecting stage-discharge relation. 

One channel at all stages. Willows on right bank.

EXTREMES OP DISCHARGE. Maximum stage during year ending September 30, 1919, 

from water-stage recorder, 1.86 feet at 10 a. m. April 13 (discharge from extension 

of rating curve, 230 second-feet); minimum stage, from water-stage recorder, 0.12 

foot September 12, 13 (discharge, 2.6 second-feet); discharge probably less than 

this during winter.

1909-1919: Maximum stage recorded, 8.3 feet January 16, 1909 (discharge, 

2,730 second-feet). Discharge estimated (gage washed out) on evenings of March 

1 and 2, 1910, about 3,000 second-feet. Creek dry at times prior to construction 

of reservoir.

ICE. Stage-discharge relation affected by ice during the coldest weather, generally 

for one or two months.

DIVERSIONS. The North Drew canal of the Goose Lake Valley Irrigation Co. diverts 

water past the station.

REGULATION. Beginning with the last part of 1912, water has been stored in the 

 reservoir of the Goose Lake Valley Irrigation Co. just above the station. A negligible quantity of water was stored prior to that time. The run-off records when 

corrected for storage are often negative during the summer as the discharge into 

the reservoir becomes too small to offset the evaporation losses.

9 See footnote to monthly-discharge table.
272 SURFACE WATER SUPPLY, 1919 AND 1920, PART XI.

ACCURACY. Stage-discharge relation changed during winter. Rating curve for 

March 26 to September 30 well denned below 70 second-feet. Operation of 

recorder satisfactory April 11 to September 30. Reading made on staff gage once 

a day October 1 to March 31 and April 5. Daily discharge ascertained by applying to rating table the daily gage reading or the mean daily gage height obtained 

by inspecting the recorder graph. Records good, except for estimated periods.

COTTONWOOD CREEK NEAR LAKEVIEW, 6REG.

LOCATION. In SW. J sec. 29, T. 38 S., R. 19 E., one-fourth of a mile below dam site 

of proposed storage reservoir, near edge of valley, and 10 miles northwest of Lakeview, Lake County.

DRAINAGE AREA. 30 square miles.

RECORDS AVAILABLE. November 22, 1908, to September 30, 1919, when station was 

discontinued.

GAGE. Barrett and Lawrence water-stage recorder on right bank; inspected by Peter 

Segner and Jake McCully. Prior to May 31, 1919, a vertical staff on left bank 

about one-fourth of a mile below was used. From November 22,1908, to January 

18, 1909, a gage just above a weir, one-fourth of a mile below the dam site, was 

used.

DISCHARGE MEASUREMENTS. Made from a footbridge 40 feet below staff gage or by 

wading.

CHANNEL AND CONTROL. Control at recorder is a rocky riffle, practically permanent; 

at staff gage, bed composed of clean gravel, somewhat shifting.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 2.8 feet April 7 

(discharge, 220 second-feet); minimum stage, 0.40 foot August 24 (discharge, 1.0 

second-foot).

1908^1919: Maximum stage recorded, 3.4 feet November 23, 1909 (discharge, 

337 second-feet); minimum stage 0.05 foot August 31 to September 3, 1918 (discharge, 0.2 second-foot).

ICE. Stage-discharge relation seriously affected by ice December to March; flow 

estimated.

DIVERSIONS. Some water diverted for irrigation in a valley above the station.

ACCURACY. Stage-discharge relation probably permanent during year at each location. Rating curves used as follows: October 1 to May 31, for staff gage, well 

defined below 120 second-feet; June 1 to September 7, for recorder, well defined. 

Staff gage read once a day up to May 31. Operation of water-stage recorder fairly 

satisfactory June 5 to August 16. Daily discharge ascertained by applying to rating 

table the daily gage reading or the mean daily gage height obtained by inspecting 

the recorder graph. Records good for June to August, fair remainder of year except 

for periods of estimated discharge.

below station.

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

1,090 square miles which belongs naturally in the 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 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, 1920. In 1879 the State 

engineer and in 1893 and 1894 the commissioner of public works made measurements at this point. From April 30, 1895, to June 30, 1902, a gaging station was 

maintained at Jellys ferry, 12 miles above Red Bluff.

GAGE. Staff in seven sections on left bank; read by Groebe. and Freemyers. January 1, 1920, a Stevens continuous water-stage recorder was installed 50 feet 

above staff gage. Several gages have been used at this station, but all observations have been reduced to the present datum. The United States Weather 

Bureau gage at Red Bluff has occasionally been used.

DISCHARGE MEASUREMENTS. Made from cable 50 feet above the gage.

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

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 30, 1919, 23.4 feet at 8.45 a. m. February 11 (discharge, 137,000 second-feet); 

minimum stage, 0.6 foot September 3-8 (discharge, 3,660 second-feet).

Maximum stage during year ending September 30, 1920, from water-stage 

recorder, 9.30 feet at 10 p. m. April 15 (discharge, 35,600 second-feet); minimum 

stage, from water-stage recorder, 0.30 foot at 2.45 p. m. August 18 (discharge, 

3,150 second-feet).

1902-1920: Maximum stage recorded, 35.2 feet February 3, 1909 (discharge, 

278,000 second-feet); minimum stage occurred in 1920.

DIVERSIONS. The 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. s

REGULATION. No storage of any importance has been developed in the drainage area 

above the station.

ACCURACY. Stage-discharge relation changed February 11, 1919. Rating curves 

well defined. Gage read to half-tenths twice daily October 1, 1918, to April 27, 

1919, and once daily May 18 to December 31, 1919, after which water-stage 

recorder was used. Daily discharge ascertained by applying daily gage reading 

or mean daily gage height to rating table. Records excellent.

ending Sept. 30, 1919 and 1920.

FEATHER RIVER AT OROVILLE, CALIF.

LOCATION. In sec. 8, T. 19 N., R. 4 E., at highway bridge at Oroville, Butte County, 

6 miles below junction of North and Middle forks and 30 miles above mouth of 

Yuba River.

DRAINAGE AREA. 3,640 square miles.

RECORDS AVAILABLE. January 1, 1902, to September 30, 1920.

GAGE. Stevens continuous water-stage recorder installed August 28, 1920, replacing 

Friez water-stage recorder in use since December 16, 1912; on right bank 200 feet 

below bridge, at same datum as United States Weather Bureau vertical staff 

which is in two sections on pier of highway bridge near right bank. Weather 

Bureau gage was used 1902 to 1905 by adding 2 feet to the readings to reduce them 

to the datum of United States Geological Survey staff gage installed on left bank 

about 1,000 feet above bridge in December, 1905. The latter gage was washed out 

several times, and, until repaired, the Weather Bureau gage was used.

DISCHARGE MEASUREMENTS. Made from cable 1,000 feet above bridge. At extreme 

low water, measurements have been made from a boat about 1,000 feet below the 

bridge.

CHANNEL AND CONTROL. Boulders and gravel; shifts somewhat during high water.

EXTREMES OP DISCHARGE. Maximum stage during year ending September 30, 1919, 

from water-stage recorder, 14.58 feet at 5 a. m. February 11 (discharge, 84,200 

second-feet); miraTtniTn stage, from water-stage recorder, 0.17 foot at 10 a. m. 

August 25 (discharge, 975 second-feet).

Maximum stage during year ending September 30, 1920, from water-stage 

recorder, 9.05 feet at 1 a. m. April 16 (discharge, 25,900 second-feet); minimum 

stage, from water-stage recorder, 0.39 foot at 11 a. m. September 29 (discharge, 

626 second-feet).

1902-1920: Maximum stage recorded, 30.2 feet on Weather Bureau gage; 39.3 

feet on gage 1,000 feet above, March 19, 1907 (discharge, 187,000 second-feet); 

minimum stage occurred in 1920 (discharge, 626 second-feet).
FEATHER RIVER BASIN. 309

DIVERSIONS. Minor diversions from tributaries above the station.

STORAGE. See North Fork of Feather River near Prattville, Calif.

REGULATION. The operation of the Big Bend plant of the Great Western Power Co. 

causes diurnal fluctuations in stage, especially during extreme low water, when 

it amounts to about a foot.

ACCURACY. Stage-discharge relation changed January 21 and April 30,1919. Rating 

curves well defined between 1,000 and 15,000 second-feet. Operation of waterstage recorder satisfactory except during periods indicated in footnote to daily 

discharge table. Daily discharge ascertained by applying mean daily gage height 

to rating tables except November 15,1918, January 19, 20, February 9-11, 1919, 

when hourly discharge was averaged. Records excellent.

SPANISH CREEK AT KEDDIE, CALLF,

LOCATION. In SW. i sec. 22, T. 25 N., R. 9 E., at highway bridge at Kiddie, Plumas 

County, 2 miles above junction with Indian Creek.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. October 22, 1911, to May 31, 1920.

GAGE. Staff gage in two sections on left bank 250 feet below bridge, used since 

October 1, 1917. First section inclined; second section vertical; fastened to 

alder trees. Gage read by Luman, Swindler, McElroy, and Norton.

Prior to August 12,1914, low-water section was a vertical staff fastened to a stump 

on left bank 20 feet below bridge and a high-water section was painted on the left 

abutment of bridge. From August 12, 1914, to September 30, 1917, gage was a 

vertical staff in three sections; first section on right bank 50 feet above bridge; 

second section on left bank 20 feet below bridge; third section fastened to down 

stream side of left bridge pier. Present gage not at same datum as previous gages.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge or by wading.

CHANNEL AND CONTROL. Boulders; practically permanent. A loose rock dam built 

on control August 19, 1919, caused a change in stage-discharge relation.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 9.5 feet at 5 p. m. February 11 (discharge, from extension of rating 

curve, about 6,900 second-feet); minimum stage 3.0 feet July 29 to August 18 

(discharge, 20 second-feet).

Maximum stage recorded during the period October 1, 1919 to May 31, 1920, 

7.0 feet at 9 a. m. April 16 (discharge, 1,520 second-feet); minimum stage, 4.1 

feet October 11-15 (discharge 37 second-feet).

1911-1920: Maximum stage recorded, 10.0 feet at 11 a. m., December 31, 1913, 

and at 1 p. m. January 2, 1914 (discharge, from extension of rating curve, about 

9,450 second-feet); minimum stage recorded, 2.95 feet August 15 and 28, 1918 

(discharge, 17 second-feet).

DIVERSIONS. Water is diverted from Spanish Creek for irrigation in American Valley.

REGULATION. None.

ACCURACY. Stage-discharge relation changed August 19 to September 6, 1919, when 

rock dam was built on control. Rating curve before change well defined between 

30 and 1,000 second-feet and is extended above and below; curve after change 

fairly well denned between 20 and 100 second-feet. Gage read to tenths twice 

daily. Gage-height record after May 31, 1920, apparently unreliable and not 

used. Daily discharge ascertained by applying mean daily gage height to rating 

table. Records fair.

MIDDLE FORK OF FEATHER RIVER AT SLOAT, CALIF.

LOCATION. Half a mile above Sloat, Plumas County, three-fourths of a mile above 

mouth of Poplar Creek, and 1£ miles below Cromberg.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. November 3, 1910, to September 30, 1920.

GAGE. Gurley graph water-stage recorder on right bank. Original gage was at 

California White Pine Co. 's log chute at Cromberg. Several changes in gage at 

that site were made. All were on downstream side of log chute piers and original 

datum was maintained. During construction of recorder well (Nov. 9-Dec. 4, 

1913) a staff gage at new site and new datum was read. From December 5, 

1913, to September 11,1917, record is from a Gurley printing water-stage recorder.

DISCHARGE MEASUREMENTS. Made from cable 1 mile above gage or by wading.

CHANNEL AND CONTROL. Boulders and gravel, practically permanent. Left bank, 

flat and timbered, overflowed at flood stages.

EXTREMES OP DISCHARGE. Maximum stage during year ending September 30, 

1919, from water-stage recorder, 6.8 feet at 6 p. m. February 10 (discharge, 4,070 

second-feet); minimum stage from water-stage recorder, 2.52 feet, September 

22-26 (discharge, 34 second-feet).

Maximum stage during year ending September 30, 1920, from water-stage 

recorder, 5.90 feet at 10 p. m. April 15 (discharge, 2,740 second-feet); minimum 

stage 2.47 feet August 15-17, September 8-10,13-16, and 21 (discharge, 28 secondfeet).

1910-1920: Maximum stage recorded, 13.0 feet April 7, 1911 (discharge, 9,640 

second-feet); minimum stage occurred in 1920 (discharge, 28 second-feet).

ICE. Stage-discharge relation affected by ice December 23 to January 6,1919.

DIVERSIONS . None.

REGULATION . None.
316 SURFACE WATER SUPPLY, 1919 AND 1920, PART XI.

ACCURACY. Stage-discharge relation has remained practically permanent since 

station was relocated in 1913; slightly affected by ice for short periods. Bating 

curve well defined below 6,000 second-feet and is extended above. Mean daily

YUBA BIVEB AT SMAKTSVILLE, CALIF.

LOCATION. In sec. 22, T. 16 N., B. 6 E., at Narrows, 1 mile north of Smartsville, Yuba 

County, 1 mile below mouth of Deer Creek, 6^ miles below mouth of South Fork, 

7 miles above mouth of Dry Creek, and 18 miles above junction with Feather River.

DRAINAGE AREA. 1,220 square miles.

RECORDS AVAILABLE. June 2,1903, to September 30,1920.

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.

DISCHARGE MEASUREMENTS. Made from cable at gage.

CHANNEL AND CONTROL. 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 ending September 

30, 1919, 14.2 feet February 11 (discharge, 29,400 second-feet); minimum stage, 

2.70 feet August 29, September 5, 6, and 27 (discharge, 155 second-feet).

Maximum stage recorded during year ending September 30, 1920, 12.3 feet at 

2.30 p. m. April 15 (discharge, 20,600 second-feet); minimum stage, 2.32 feet August 

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

1903-1920: Maximum stage recorded, 28.3 feet January 15, 1909 (discharge. 

111,000 second-feet); minimum stage occurred in 1920 (discharge, 106 secondfeet).
328 SURFACE WATER SUPPLY, 1919 AND 1920, PART XI.

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

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

River are utilized as storage reservoirs. A part of this water is diverted into the 

Bear River drainage basins.

ACCURACY. Stage-discharge relation changed during high water of January 20, February 11, May 3, and December 11,1919, and April 15, 1920. Rating curves fairly 

well defined. Gage read to half-tenths once daily. Daily discharge ascertained 

by applying gage height to rating table. Records good.

below bridge; section 2 on right bank 35 feet below bridge. From December ]8, 

1912, to August 16, 1914, a Gurley printing water-stage recorder was in operation 

on the right bank 50 feet below the bridge at the same datum. Gage read by 

Henning and Finch".

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Gravel and small boulders tailings from placer mining; 

shift during high water. Banks high, rocky, wooded, and not subject to overflow.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 10.8 feet at 5.30 p. m. February 10 (discharge, 12,000 second-feet); 

minimum stage, 1.70 feet September 26-28 (discharge, 40 second-feet).

AMERICAN RIVER AT FAIROAKS, CALIF.

LOCATION. At highway bridge 1,500 feet northwest of Southern Pacific Co.'s railroad 

station at Fairoaks Bridge, half a mile southeast of Fairoaks, Sacramento County, 

and 10 miles below mouth of South Fork.

DRAINAGE AREA. 1,910 square miles.

RECORDS AVAILABLE. November 3, 1904, to September 30, 1920.

GAGE. Gurley graph water-stage recorder on right bank 800 feet below bridge. A 

temporary vertical staff gage on right bank 60 feet above bridge was used October 1, 

1918, to February 9, 1919, and June 1, 1919, to September 30, 1920. Datum of 

temporary gage raised 0.09 foot August 30, 1920, to agree with gage painted on 

bridge pier. The gage at the bridge was used February 10,1919, and February 26 

to March 8, 1919. Previous to January 18, 1914, several staff gages at right abutment of bridge were used. From January 18, 1914, to August 24, 1916, and 

December 9, 1916, to July 21, 1917, the record is from a Gurley printing waterstage recorder at same site as present gage. A temporary gage near bridge was 

used when recorder could not be operated.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge or by wading.

CHANNEL AND CONTROL. Gravel and small boulders; shifts during high water.
350 SURFACE WATER SUPPLY, 1919 AND 1920, PART XI.

EXTREMES OF DISCHARGE. Maximum stage during year ending September 30, 1919, 

from water-stage recorder, 18.5 feet February 11 (discharge, 67,500 second-feet); 

minimum stage, 0.66 foot on temporary gage August 29 (discharge, 92 second-feet). 

Maximum stage recorded during year ending September 30, 1920, 10.6 feet 

(gage at bridge) at 8 a. m. April 16 (discharge, 20,100 second-feet); minimum 

stage, 0.40 foot September 23-27 (discharge, 100 second-feet).

1907-1920: Maximum stage recorded, 30.4 feet March 19, 1907 (discharge, from 

extension of rating curve, about 119,000 second-feet); minimum stage, 2.01 feet 

from 8 to 10.30 a. m. September 24, 1915 (discharge, from extension of low-water 

curve, about 25 second-feet).

DIVERSIONS. Water is diverted for irrigation above station.

REGULATION. See descriptions of Middle, North, and South forks. Low-water flow 

partly regulated by power plant at Folsom.

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

gages were used as noted under "Gage." Staff gages read to tenths twice daily 

October 1, 1918, to March 8, 1919, and to hundredths twice daily April 1, 1919, to 

September 30, 1920. Rating curves are fairly well denned. Mean daily gage 

height determined by inspection of the water-stage recorder graph or by averaging 

daily staff-gage readings. Daily discharge ascertained by applying mean daily 

gage height to rating table. For periods when gages were not read (see footnote 

to daily-discharge table) discharge estimated from Weather Bureau gage height? 

at Folsom. Records good.

LOCATION. In SE. \ sec. 6, T. 12 N., R. 9 E., at Mountain Quarry Co.'s plant, 1J 

miles above junction with North Fork of American River and 3£ miles northeast 

of East Auburn, Placer County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. October 22, 1911, to September 30, 1920.

GAGE. Staff in four sections on left bank at pump house; read by J. A. Collins.

DISCHARGE MEASUREMENTS. Made from cable 700 feet below gage or by wading.

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

high and not subject to overflow.

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 17.5 feet, from flood marks, February 11 (discharge, 25,000 second-feet); 

minimum stage, 2.45 feet September 22-28 (discharge, 54 second-feet).

Maximum stage recorded during year ending Sept. 30, 1920, 10.5 feet at 8 a. m. 

April 16 (discharge, 9,000 second-feet); minimum stage, 2.55 feet September 6-9 

(discharge, 46 second-feet).

1911-1920: Maximum stage recorded, 18.0 feet at 7 a. m. January 1, 1914 (discharge, from extension of rating curve, about 26,400 second-feet); minimum stage, 

1.0 foot at 7. a. m. October 23, 24, and 31,1915 (discharge, 32 second-feet).

DIVERSIONS. Pilot Creek ditch diverts from Pilot Creek for irrigation on Georgetown 

divide. Little South Fork ditch diverts from Gerle Creek and discharges into 

Pilot Creek drainage basin where it is used when necessary to supplement the flow 

in Pilot Creek ditch; maximum discharge is probably less than 20 second-feet.

REGULATION. Storagels developed in Loon Lake at the head of Gerle Creek to serve 

the ditches mentioned in the preceding paragraph.
AMERICAN EIVEE BASIN. 353

16, 1920. Rating curve used October 1, 1918, to February 11, 1919, fairly well 

defined below 5,000 second-feet; curve used February 12 to May 1, 1919, fairly 

well defined; curve used May 1, 1919, to April 16, 1920, well defined below 4,000 

second-feet, and extended above 4,000 second-feet; curve used April 16 to September 30, 1920, fairly well defined. Gage read to half-tenths twice daily.

Maximum stage recorded during year ending September 30, 1920, 9.75 feet 

at 9 a. m. April 16 (discharge, 3,840 second-feet); minimum stage, 3.58 feet at 

2.30 p. m. September 21 (discharge from discharge measurement, 49 secondfeet).

1911-1920: Maximum stage recorded, 19.0 feet at 4 p. m. January 25, 1914 

(discharge, from extension of rating curve, about 15,000 second-feet); minimum

DIVERSIONS. Water is diverted just below the mouth of Silver Fork for irrigation, 

mining, and municipal supply for Placerville. Power is developed near the 

mouth of Rock Creek by the Western States Gas & Electric Co. At low water the 

entire flow of the South Fork of American River is diverted for power; occasionally 

the quantity is insufficient and additional water is purchased from the Sierra 

Water Supply Co. The water diverted for power is returned to the river above 

the gaging station.

REGULATION. Echo and Silver lakes are used as storage reservoirs.

ACCURACY. Stage-discharge relation changed February 11, 1919. Rating curves 

well defined below 5,000 second-feet and extended above. Gage read to hundredths once daily. Daily discharge ascertained by applying gage height to 

rating table. Records excellent.

EEL RIVER BASIN. 

EEL RIVER AT SCOTIA, CALIF.

LOCATION. In sec. 18, T. 1 N., R. 1 E., at Wild wood 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, 1915; October 1, 1916, to 

September 30, 1920.

GAGE. Staff gage in eight sections, read by Bixler and 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 ending September 

30, 1919, 38.3 feet at noon January 17 (discharge, 149,000 second-feet); minimum 

stage, 8.82 feet at 7 p. m. September 2 (discharge, 63 second-feet).

Maximum stage recorded during year ending September 30, 1920, 25.0 feet at 

7.30 a. m. April 16 (discharge, 62,000 second-feet); minimum stage, 8.84 feet 

September 9-11 (discharge, 40 second-feet).

1911-1920: Maximum stage recorded, 55.5 feet February 2, 1915 (discharge, 

from extension of rating curve, about 290,000 second-feet); minimum stage 

occurred in 1920 (discharge, 40 second-feet).
364 SURFACE WATER SUPPLY, 1919 AND 1920, PART XI.

ACCURACY. Stage-discharge relation at low water changed January 17,1919, and April 

16, 1920. Rating curves well denned below 120,000 second-feet and extended 

above. Gage read to hundredths twice daily. Daily discharge ascertained by 

applying mean daily gage height to rating table. Records good.

KLAMATH RIVER BASIN. 369

WILLIAMSON RIVER ABOVE SPRING CREEK, NEAR KLAMATH AGENCY, OREG.

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 to September 30, 1920. 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 an inflow of a few 

second-feet from springs below Rocky Ford.

GAGE. Stevens continuous recorder on left bank. Temporary gage at Kirk sawmill, 

about 6 miles upstream, read October 29,1918, to March 31,1919.

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

same section.

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

one channel at all stages. Control is riffle 200 feet below gage. Stage-discharge 

relation Ls probably affected by growth of aquatic plants. No definite control at 

temporary gage.

EXTREMES OF DISCHARGE. Maximum stage during year ending September 30, 1919, 

from water-stage recorder 3.84 feet, at 3 a. m. April 13 (discharge estimated from 

extension of rating curve, 1,220 second-feet); minimum stage recorded 0.02 foot 

August 23 (discharge, 25 second-feet); stage was probably slightly lower in September.

Maximum stage during year ending September 30, 1920, probably occurred in 

March when recorder was not operating; minimum stage from water-stage recorder 

 0.19 foot at 11 p. m. July 26 (discharge, 15 second-feet).

ICE. Practically no ice in river at regular gage; river frozen from December 17 to some 

time in March, at temporary gage.

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 twice during periods of record. Three 

well-defined rating curves used. Operation of recorder fairly satisfactory. Daily 

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

obtained by inspecting the recorder graph. For temporary station, stage discharge 

relation probably permanent except as affected by ice. Rating curve poorly

defined, gage read to hundredths

1918, and January, 1919, on account of ice and for April, 1919, on account of lack

of high-water measurements; fair 

1918-19 and good for 1920.

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

DRAINAGE AREA. 2,810 square miles.

RECORDS AVAILABLE. June 25, 1917, to September 30, 1920. The sum of discharge 

records at stations on Williamson and Sprague rivers above their junction is 

directly comparable with these records.

{JAGE. Friez water-stage recorder on left bank with inside hook and outside staff gage.

DISCHARGE MEASUREMENTS. Made from cable at gage.

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

somewhat uneven.

EXTREMES OF DISCHARGE. Maximum stage during year ending September 30, 1919, 

from water-stage recorder, 3.57 feet at 3 a. m. April 9 (discharge, 3,480 secondfeet); minimum stage from water-stage recorder, 0.63 foot at 10 a. m. July 13 (discharge, 485 second-feet); total including canal about 515 second-feet.

Maximum stage during year ending September 30, 1920, from water-stage recorder, 2.61 feet at 2 a. m. March 28 (discharge, 2,290 second-feet); minimum 

stage from water-stage recorder, 0.47 foot at noon July 24 (discharge, 356 secondfeet).

1911-1920: Maximum discharge obtained by adding results obtained at stations 

above junction, about 7,000 second-feet April 27, 1917; Williamson River estimated as 2,500 second-feet. Minimum stage occurred in 1920.

ICE. Stage-discharge relation not affected by ice during 1919; not seriously affected 

in 1920.

372 SURFACE WATER SUPPLY, 1919 AND 1920, PART XI.

ACCURACY. Stage-discharge relation changed during January, 1920. Rating curves 

well denned. Gage-height record good except for few short periods. Daily discharge ascertained by applying to the rating table the mean daily gage heights 

obtained by inspecting the recorder graph, or in times of considerable fluctuation 

by subdividing days. Records good.

COOPERATION. Part of field data furnished by U. S. Reclamation Service, H. D. 

Newell, project manager.

374 SURFACE WATER SUPPLY, 1919 AND 1920, PART XI.

TIPPER KLAMATH LAKE NEAR KLAMATH FALLS, OREG.

LOCATION. In sec. 30, T. 38 S., R. 9. E., at outlet of Upper Klamath Lake, 2 miles' 

northwest of Klamath Falls, Klamath County.

RECORDS AVAILABLE. May 28, 1904, to September 30, 1920; records from October 23,. 

1904, to December 31, 1905, have not previously been published.

GAGE. Friez water-stage recorder February 16, 1906,toJune 16,1918; since that datevertical staff read about once a week. Zero on gage is 4,136.13 feet above sea 

level. Gage readings 1918, 1919, and 1920 reduced to a datum of 4,100 feet. During 1904 and 1905, vertical staff on Pelican Bay; zero, 4,137.78 feet above sea leve1 

(United States Reclamation Service datum) as determined by E. G. LaRue in 

June, 1920.

EXTREMES OP STAGE. 1919: Maximum stage recorded during year, 42.38 feet June 

7; minimum stage recorded, 40.08 feet September 6.

1920: Maximum stage recorded during year, 42.43 feet April 18; minimum stage 

recorded, 40.13 feet September 11.

1904-1920: Maximum stage, 4,144.98 feet (United States Reclamation Servicedatum) about April 20, 1904, determined from high-water marks May 28, 1904; 

minimum stage recorded, 4,039.63 feet September 2 and November 5, 1917 (stagesomewhat lower in July, 1918, recorder not working).

FLUCTUATION. Gage heights are very much affected by the wind. The water i& 

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 opposite direction. There is a. 

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

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

1919.

376 SURFACE WATER SUPPLY, 1919 AND 1920, PART XI.

LINK RIVER AT KLAMATH FALLS, OREG.

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

bridge over Link River, 1| miles below outlet of Upper Klamath Lake, and imme 

diately above head of Lake Ewauna at Klamath Falls, Klamath County. 

"DRAINAGE AREA. 3,110square milea.

RECORDS AVAILABLE. May 15, 1904, to September 30, 1920.

GAGE. Friez water-atage recorder on left bank; elevation of zero ia 4,080.0 feet above 

sea level. Friez recorder on opposite bank and a little farther upstream was 

used June 6, 1908, to Auguat 30, 1912. Chain gage on the bridge uaed 1904 to 

1908. Gage reader, Marie Talbot.

DISCHARGE MEASUREMENTS. Made from bridge, aection deep, current aluggish at 

low water.

CHANNEL AND CONTROL. Bed composed of mud and sand with rock and boulder 

rapids. Rock and boulder riffle a short distance below gage affords fairly permanent control. Stage-discharge relation at chain gage is affected by backwater from Lake Ewauna and wind. Water from the tailrace of the CaliforniaOregon Power Co.'s plant, which enters the river opposite the gage appears to 

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

EXTREMES OF DISCHARGE. Maximum stage during year ending September 30, 1919, 

from water-stage recorder, 6.95 feet at 8 p. m. April 7 (discharge, 3,430 secondfeet); minimum stage during year from recorder, 4.47 feet at 4 p. m. August 30 

(discharge, 356 second-feet).

Maximum stage during year ending September 30, 1920, from water-stage 

recorder, 6.00 feet at noon December 25 (discharge, 2,000 second-feet); minimum 

stage, from water-stage recorder, 4.64 feet at 5 p. m. September 19 (discharge, 492 

second-feet).

1904-1920: Maximum stage, 7.30 feet at gage at bridge May 12, 19*04, determined May 15, 1904, from high-water marks (discharge, 9,400 second-feet); minimum stage, 4.07 feet August 30, 1918, determined by leveling (discharge esti- 

. mated 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 Reclamation Service diverts water from Link River immediately below Upper 

Klamath Lake. Record is kept of this diversion (see p. 410). 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 a temporary dam beginning 

April 15, 1919. Marked natural fluctuations are caused by effect of wind on 

Upper Klamath Lake.

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

defined. Operation of recorder unsatisfactory on account of failure of observer 

to read staff gage in many instances. Staff gage read once a day by CaliforniaOregon Power Co., March 1 to September 30, 1920. Daily discharge ascertained 

by applying to rating table the mean daily gage height obtained by inspecting 

the recorder graph. Records good most of the time, uncertain for a few periods 

owing to questionable gage-height record, but in general it is consistent with 

that for Klamath River at Spencer Bridge.

COOPERATION. Most of field, data furnished by United States Reclamation Service, 

H. D. Newell, project manager. Results of several discharge measurements, 

furnished by California-Oregon Power Co.

380 SUEFACE WATER SUPPLY, 1919 AND 1920, PART XI.

KLAMATH RIVER AT SPENCER BRIDGE, FEAR KENO, OREG.

LOCATION. In sec. 32, T. 39 S., R. 7 E., at highway bridge 1 mile below Spencer

Creek, 6 miles below former station at Keno, and 18 miles west, on road to Ashland, from Klamath Falls, Klamath County. 

DRAINAGE AREA. Not measured. 

RECORDS AVAILABLE. October 7, 1913, to September 30, 1920. Records at Keno,

May 31, 1904, to December 31, 1913, give results smaller by the relatively small

flow contributed by Spencer Creek. 

GAGE. Vertical staff near upstream end of first concrete pier at east end of bridge.

Datum lowered 1.0 foot June 21, 1918. Gage reader, Esther Anderson. 

DISCHARGE MEASUREMENTS. Made from upstream side of wagon bridge or by wadinp

at low water just above the bridge. 

CHANNEL AND CONTROL. Heavy gravel and boulders; practically permanent; bee1

even. 

EXTREMES OP DISCHARGE. Maximum stage recorded during year ending September

30, 1920, 2.65 feet April 17 (discharge, 3,430 second-feet); minimum stage recorded, 0.88 foot August 28 (discharge, 820 second-feet). 

Maximum stage recorded during year ending September 30, 1920, 1.70 fee*.

February 10, 12, and 14 (discharge, 1,840 second-feet); minimum stage recorded.

0.82 foot August 26 (discharge, 720 second-feet). 

1904-1920: Maximum stage recorded at Keno, 15.3 feet about May 10, 1904,

from high-water marks observed May 31 (discharge, 9,250 second-feet); minimurr

stage recorded, 0.38 foot August 3, 1918 (discharge, 386 second-feet), 

ICE. Stage-discharge relation not affected by ice. 

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 between Klamath Falls and Keno stations. 

REGULATION. Water stored in Upper Klamath Lake by California-Oregon Power

Co., beginning April 15, 1919. Some natural regulation owing to effect of wind

on the wide flat stretches of river above Keno. 

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

defined. Gage read about three times a week to hundredths. Daily discharge

ascertained by applying the daily gage reading to rating table. Records good. 

COOPERATION. Field data furnished by United States Reclamation Service, H. D,

Newell, project manager, Klamath project.

Discharge measurements of Klamath River at Spencer Bridge, near Keno, Oreg., durinft 

the years ending Sept. 30, 1919 and 1920.

SPRAGTJE RIVER NEAR BEATTY, OREG.

LOCATION. In NW. J sec. 20, T. 36 S., R. 13 E., 2 miles above highway bridge on road 

from Yainax to Silver Lake, 4 miles above mouth of Sycan River, and 3 miles 

east of Beatty post office, Klamath County.

DRAINAGE AREA. 513 square miles.

RECORDS AVAILABLE. April 19,1912, to September 30,1920, fragmentary.
390 SURFACE WATER SUPPLY, 1919 AND 1920, PART XI.

GAGE. Vertical staff gage with duplicate inclined section on left bank. Stevens 

water-stage recorder at same location used February 20, 1914, to September 11, 

1917; gage readers, C. G. Burk and E. B. Henry.

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 this station.

DISCHARGE MEASUREMENTS. Made from cable about 100 feet below gage; at high 

stages, from wagon bridge 2 miles downstream, and inflow estimated.

EXTREMES OF DISCHARGE. Maximum stage during 1919 probably occurred about 

April 4, no record. Minimum stage recorded, 0.50 foot July 6-19 (discharge, 98 

second-feet). a

Maximum stage recorded during 1920, 2. 6 feet May 10 (discharge, 277 secondfeet); minimum stage recorded, 0.56 foot September 18 (estimated discharge, 

66 second-feet).

1912-1920: Maximum stage from water-stage recorded, 5.75 feet April 24, 1917 

(discharge, 1,320 second-feet); minimum stage recorded, 0.66 foot September 18, 

1920 (estimated discharge, 66 second-feet). Discharge of 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 high water of April, 1919, and 

during winter of 1919-20. Well defined rating curves used. Gage read once a 

day to hundredths in February and March 1919; to tenths thereafter. Some of 

gage readings for 1920 questionable. Daily discharge ascertained by applying to 

rating table the daily gage reading directly except during November, December, 

and January, 1919, when the shifting-control method was used. Records good 

for 1919, fair for 1920.

SPRAGUE RIVER AT CHILOQDTN, OREG.

LOCATION. In NE. \ sec. 3, T. 35 S., R. 7 E., half a mile above mouth and same 

distance above Southern Pacific Railroad bridge (where station was located before 

October 31,1914), half a mile below diversion dam of Modoc Point canal of United 

States Indian Service, and three-fourths mile south of Chiloquin, Klamath County.

DRAINAGE AREA. 1,550 square miles.

RECORDS AVAILABLE. July 25, 1911, to September 30, 1919; partly fragmentary. 

Station discontinued.

GAGE. Friez water-stage recorder on right bank 500 feet above wagon bridge, installed 

June 25, 1917. Vertical "staff on wagon bridge was read November 1, 1914, to 

June 25,1917, and a chain gage on railroad bridge before October 31, 1914. Gage 

reader, Anna McKeever.

DISCHARGE MEASUREMENTS. Made from upstream side of wagon bridge.

CHANNEL AND CONTROL. Bed and control composed of rocks and boulders; may shift 

slightly; obstructed by logs April 29 to May 10, 1918, and beginning about April 

1,1919.

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

3.12 feet April 8 (stage-discharge relation affected by logs); minimum stage from 

water-stage recorder, 0.65 foot August 4 and 26, caused by holding water behind 

splash dam above (discharge, about 120 second-feet).

1911-1919: Maximum stage recorded, 5.3 feet March 28, 1917 (discharge, 4,490 

second-feet); minimum unregulated discharge, 208 second-feet, or 248 second-feet 

including Modoc Point canal, July 15 and 16, 1918.

ICE. Stage-discharge relation affected by ice only during short periods of extremely 

cold weather.

DIVERSIONS. The Modoc Point canal, completed in 1915, diverted some water around 

the gage, of which a record was kept, see page 406. A considerable quantity of 

water is also diverted for irrigation in the headwaters of Sprague and Sycan rivers.

REGULATION. Manipulation of sluiceway of diversion dam may cause some fluctuation at the gage. Beginning in July, 1919, a splash dam was also operated a few 

miles above the station.

ACCURACY. Stage-discharge relation practically permanent October to March; 

affected by log obstruction thereafter, and no daily discharge can be computed. 

Rating curve well defined. Operation of recorder satisfactory except for a few 

short periods for which discharge is estimated. Daily discharge ascertained by 

applying to rating table the mean daily gage height obtained by inspecting the 

recorder graph. Records good except for January for which they are fair.

FIVEMILE CREEK NEAR ELY, OREG.

LOCATION. In sec. 34, T. 35 S., R. 13 E., 4 miles above mouth and 10 miles northeast of Beatty, Klamath County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. September 8, 1917, to September 30, 1920, fragmentary.

GAGE. Vertical staff on right bank installed May 11, 1919, Stevens 8-day recorder 

on left bank and vertical staff about 1 mile above mouth, in sec. 1, T. 36 S., used 

prior to May 11.

DISCHARGE MEASUREMENTS. Made by wading near gage.

CHANNEL AND CONTROL. Bed of small boulders. Control is a rocky riffle about 25 

feet below gage. At old station channel crooked and lined with thick growth of 

willows. An artifical control consisting of a log with sheet piling driven on the 

upstream side was installed September 14, 1917, but was unsatisfactory owing to 

washing around ends.

EXTREMES OF DISCHARGE. Maximum stage during 1919 indicated by water-stage 

recorder, clock stopped; 2.7 feet on old gage, probably about April 4 (discharge 

estimated from extension of curve 112 second-feet); minimum stage recorded 

during year, 0.92 foot, July 12 (discharge, 20 second-feet).

Maximum discharge reported during 1920, 24 second-feet on April 14; minimum 

discharge reported 18 second-feet throughout July.

1917-1920: Maximum stage that of 1919: minimum discharge, 18 second-feet, 

July, 1920.
KLAMATH RIVER BASIN. 395

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

DIVERSION. None above gages, two ditches divert between former gage section and 

mouth of stream.

REGULATION. None.

ACCURACY. Stage-discharge relation at first station apparently permanent during 

year, somewhat unstable at present station. Fairly well denned rating curves 

used February 7 to May 11, and June 14 to September 30, 1919. Shifting-control 

method used May 17 to June 7, 1919, and throughout 1920. Recorder operated 

February 7-14, April 5-12, and April 22 to May 6, 1919. Gage read once or 

twice a week May 11 to September 30, 1919, and April 1 to September 30, 1920. 

Daily discharge ascertained by applying to rating table the mean daily gage 

height obtained by inspecting the recorder graph, or the daily gage reading, 

either directly or by shifting-control method. Records fair.

KLAMATH RIVER BASIN. 397

SYCAN RIVER NEAR SILVER LAKE, OREG.

LOCATION. In sec. 21, T. 32 S., R. 14 E., one-fourth mile above upper diversion dam 

for Sycan Marsh, 1 mile above ZX ranch house, and 30 miles south of Silver Lake, 

Lake County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. May 10 to October 31, 1918, April 21 to September 30, 1919, 

and March 22 to June 10, 1920. May 2 to October 28, 1905, at former station at 

bridge.

GAGE. Stevens 8-day recorder on right bank inspected by C. A. Jeffries and H. T. 

Stanley.

DISCHARGE MEASURMENTS. Made by wading near gage at low and medium stages; 

from wagon bridge three-fourths mile below gage at high stages.

CHANNEL AND CONTROL. Gravel bed somewhat shifting, baliks of silt and soil, with 

scattered willows; banks overflowed in extreme floods.

EXTREMES OF DISCHARGE. Maximum stage during spring of 1919 observed from highwater marks, 4.72 feet, probably April 28 or 29 (discharge, estimated from extension of rating curve, 800 second-feet); minimum stage from water-stage recorder, 

0.28 foot August 22 to 25 (discharge, 2.2 second-feet). 

1920: Recorder not operating when maximum or minimum stages occurred.

ICE. Stream probably freezes nearly solid in winter.

DIVERSIONS. None above station; most of the water is applied to Sycan Marsh by 

flooding, from several dams and ditches.

REGULATION. None.

ACCURACY. Stage-discharge relation changed during winter when record was 

suspended. Fairly well denned rating curves used. Operation of water-stage 

recorder fairly satisfactory during irrigation seasons. Daily discharge ascertained 

by applying to rating table the mean daily gage heights obtained by inspecting 

the recorder graph. Records good, except for estimated periods.

SYCAN RIVER NEAR BEATTY, OREG.

LOCATION. In SE. J sec. 8, T. 35 S., R. 12 E., 8 miles by stream above mouth, 11 

miles by road north of Beafty, and 18 miles northeast of Yainax, Klamath County.

DKAINAGE AREA. Not measured.

RECORDS AVAILABLE. October 29, 1917, to September 30, 1920; November 25, 1911, 

to October 30,1917, at station referred to as Sycan River near Yainax.

GAGE. Stevens water-stage recorder on left bank; inspected by J. L. Richards and 

A. S. Hotchkin. Vertical staff in sec. 3, T. 36 S., R. 12 E., about 6 miles below 

present gage, was used 1911 to 1913, and recorder in NE. J sec. 28, about 3 miles 

below present gage, up to October 29, 1917.

DISCHARGE MEASUREMENTS. Made from cable 200 feet upstream from gage or by 

wading.

CHANNEL AND CONTROL. Stream bed, gravel and small boulders, fairly even; control 

of boulders about 100 feet below gage, fairly permanent. One straight channel 

at all stages; banks not subject to overflow.

EXTREMES OF DISCHARGE. Maximum stage during 1919 from water-stage recorder, 

4.25 feet at 3 p. m. April 25, lasting for only a few minutes, caused by the breaking 

of an ice jam (discharge, 1,600 second-feet). Maximum stage lasting for any considerable time was 4.0 feet at 5 a. m. April 4 (discharge, 1,420 second-feet). 

Minimum stage, from water-stage recorder, 0.12 foot March 7 (discharge, 9.4 

second feet).

1920: Recorder not operating at times when extremes occurred. 

1911-1919: Maximum stage at station in sec. 28,11.25 feet, April 25, 1917 (discharge, 2,250 second-feet); minimum that of 1919.

ICE. Stage-discharge relation not affected by ice, as most of winter flow comes from 

springs.

DIVERSIONS. Some water is used for irrigation by flooding.

REGULATION. None.
400 SURFACE WATER SUPPLY, 1919 AND 1920, PART XI.

ACCURACY. Stage-discharge relation changed slightly during spring of 1919 and 

during spring of 1920. Rating curves well defined below 700 second-feet and 

identical above 90 second-feet. Operation of water-stage recorder satisfactory 

from November 30, 1918, to September 30, 1919, except for short periods; unsatisfactory during 1920 owing to clock's stopping. Daily discharge ascertained by 

applying to rating table the mean daily gage height obtained by inspecting the 

recorder graph. Records good except for estimated periods for which they are 

fair.

LONG CREEK NEAR SILVER LAKE, OREG.

LOCATION. In sec. 4, T. 32 S., R. 13 Ev 27 miles south of Silver Lake, Lake County,

above point where creek begins to divide and spread over marsh. 

DRAINAGE AREA. Not measured. 

RECORDS AVAILABLE. May 13 to November 6, 1918, April 20 to August 31, 1919, and

March 20 to August 25, 1920. 

GAGE. Stevens continuous recorder installed on left bank of creek with outside

staff gage.

DISCHARGE MEASUREMEMTS. Made by wading below gage. 

CHANNEL AND CONTROL. Stream bed crooked and deep, vertical sod banks with

scattered growth of willows; no definite control, beaver dams may occasionally

cause backwater. 

EXTREMES OF DISCHARGE. Maximum stage during 1919, observed from high-water

marks April 20, was about 2.95 feet (discharge, 108 second-feet); minimum stage

recorded, 0.38 foot at time of measurement August 30 (discharge, 5.7 second-feet). 

Maximum stage during 1920 from water-stage recorder, 2.45 feet at noon May 9

(discharge, 66 second-feet); minimum discharge, 6. 2 second-feet August 7 and 8. 

ICE. No record during winter. 

DIVERSIONS. None above station; water is spread over meadows below station by

numerous dams. 

REGULATION. None. 

ACCURACY. Stage-discharge relation practically permanent during 1919; changed

for stages above 1.5 feet during high water in 1920. Rating curves fairly well

denned. Operation of recorder unsatisfactory. Daily discharge ascertained by

applying to rating table the mean daily gage height obtained by inspecting the

recorder graph. Records fair.

410 SURFACE WATER SUPPLY, 1919 AND 1920, PART XI.

A CANAL AT KLAMATH FALLS, OREG.

LOCATION. In NW. £ sec. 29, T. 38 S., R. 9 E., at head of tunnel one-fourth mile 

below headgates of canal and 1 mile northwest of Klamath Falls, Klamath County.

RECORDS AVAILABLE. Irrigation seasons, 1911-1920. 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 above weir. 

Barrett & Lawrence water-stage recorder used prior to 1917.

DISCHARGE MEASUREMENTS. Made from a foot plank just inside lower end of tunnel 

about half a mile below gage; rectangular section, 13.5 feet wide.

CHANNEL AND CONTROL. Trapezoidal weir, 18.15 feet long, with its crest 7.27 feet 

above bottom of canal, which is a concrete-lined section 13.5 feet wide on the 

bottom, 12 feet deep, and with side slopes \ to 1; canal has become partly filled 

with debris, which has fallen in from the sides.

EXTREMES OP DISCHARGE. Maximum stage during 1919 from water-stage recorder, 

3.82 feet at 3 p. m. May 28 (discharge, 550 second-feet).

Maximum stage during 1920 from water-stage recorder, 4.06 feet at 3 p. m. 

May 25 (discharge, 640 second-feet). 

191JL-1920: Maximum discharge that of 1920. Minimum discharge, zero.

ACCURACY. Stage-discharge relation unstable. Discharge for given gage height 

increasing from year to year as velocity of approach becomes greater owing to 

filling up of canal above weir. Rating curve for 1919 interpolated between those 

for 1916 and 1920; for 1920 well defined. Operation of water-stage recorder 

satisfactory except during June, 1919. Daily discharge ascertained by applying 

to the rating table mean daily gage height determined by inspecting of gageheight graph. Record for 1919, fair; 1920, good.

COOPERATION. Data furnished by United States Reclamation Service.

This canal diverts water from Link River immediately below outlet of Upper 

Klamath Lake, in the NE. \ sec. 30, T. 38 S., R. 9 E., for irrigating lands east of 

Klamath River on both sides of Lost River. Most of the return waters reach Lost 

River.

412 SURFACE WATER SUPPLY, 1919 AND 1920, PART XI, 

LOST RIVER AT WILSON BRIDGE, NEAR OLENE, OREG.

LOCATION. On line between sees. 29 and 30, T. 39 S., R. 10 E., at Wilson Bridge, 

one-fourth mile below diversion dam and 4 miles by river below Olene, Klamath 

County.

RECORDS AVAILABLE. March 14, 1912, to September 30, 1920, when station was 

discontinued.

DRAINAGE AREA. Not measured.

GAGE. Gurley 8-day recorder, referred to vertical staff fastened to highway bridge. 

Zero of gage, 4,005.01 feet above sea level or 0.17 foot lower than previous datum. 

Gage inspected by watchman for dam.

DISCHARGE MEASUREMENTS. Made from highway bridge.

CHANNEL AND CONTROL. Gravel and chalk rock; clean and fairly permanent.

EXTREMES OF DISCHARGE. Maximum stage during year ending September 30, 1919, 

from water-stage recorder, 72.1 feet at noon April 6 (discharge, 2,190 second-feet); 

minimum discharge estimated as 6 second-feet (leakage through flashboards) 

October 1 to March 24 and May 1 to September 30.

Maximum stage during year ending September 30, 1920, from water-stage 

recorder, 61.0 feet March 27 (discharge, 120 second-feet); minimum discharge estimated 6 second-feet October 1 to March 23, March 30 to April 18 and April 22 to 

September 30.

1904-1920: Maximum stage recorded, 18.5 feet during night of February 6,1907, 

at Merrill station (discharge, 9,600 second-feet). The maximum stage for Olene 

station was 13.5 feet early in 1904, determined from high-water marks by John 

H. Lewis, May 24, 1904 (discharge, from partly developed rating curve, 8,600 

second-feet). Minimum stage recorded for natural flow conditions, 4.29 feet June 

19, 1911, at Olene (discharge, 58 second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. This station is just below the dam at which practically all the discharge of Lost River up to about 500 second-feet is diverted through the diversion 

canal into Klamath River or into G canal on the east bank of river. A considerable portion of the low-water flow of Lost River is now diverted by pumping, and 

water is diverted into Lost River from Upper Klamath Lake; no record of this 

diversion in 1919.

REGULATION. Considerable pondage at dam.

ACCURACY. Stage-discharge relation practically permanent during 1919; assumed 

permanent during 1920. Rating curve well defined. Operation of recorder satisfactory except April 1-7, 1919, for which daily gage readings were used. Daily 

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

obtained by inspecting the recorder graph. Records good.

COOPERATION. Field data furnished by United States Reclamation Service, H. D. 

Newell, project manager.

Discharge measurements of Lost River at Wilson Bridge, near Olene, Oreg., during the

year ending Sept. 30, 1919.

Maximum stage during year ending September 30, 1920, from water-stage 

recorder, 7.1 feet at 2 a. m. April 18 (discharge, 1,410 second-feet); minim urn 

stage not recorded, stream practically dry.

1904-1920: Maximum stage recorded, 14.0 feet February 5, 1907 (discharge, 

6,730 second-feet).
KLAMATH K1VER BASIN. 417

ICE. Stage-discharge relation affected by ice, as control remains unobstructed.

DIVERSIONS. A small irrigating flume, carrying about 1 second-foot, diverts water 

above the station.

REGULATION. Flow may be occasionally affected by a rock and brush diversion 

dam just above gage.

ACCURACY. Stage-discharge relation practically permanent during 1919; assumed 

permanent during 1920. Rating curve fairly well defined. Operation of waterstage recorder fairly satisfactory. Daily discharge ascertained by applying to 

rating table mean daily gage height obtained by inspecting recorder graph. 

Records good.

COOPERATION. Field data furnished by United States Reclamation Service, Klamath 

project, H. D. Newell, project manager.

KLAMATH EIVEB BASIN. 419

LOST RIVER DIVERSION CANAL NEAR OLENE, OBEO."

LOCATION. In SW. J sec. 29, T. 39 S., R. 10 E., at intake of canal at Lost River dam, 

4 miles below Olene, Klamath County.

RECORDS AVAILABLE. May 1, ^912, to March 31, 1916, and October 1,1918, to September 30, 1920; records April 1, 1916, to September 30, 1918, obtained at a station referred to as "near Klamath Falls, Oreg."

GAGE. Vertical staffs showing height of water in pond back of headgates and in canal 

below gates read once a day. Records for the station near Klamath Falls obtained by use of two Gurley 8-day water-stage recorders at stations 85 and 330 of 

the canal.

GATE OPENINGS. The headworks of the canal comprise three hand operating sliding 

gates, each 4 feet wide and 6 feet high. The gate openings are recorded each day, 

and for each period of less than a day when the gates are changed. Water from 

Klamath River backs up the canal nearly to its head, even if no water is running.

DISCHARGE MEASUREMENTS. Made from a footbridge a short distance below the 

headgate.

DISCHARGE COEFFICIENTS. Tables of discharge coefficients and velocity for computing the flow through the gates considered as orifices have been deducted by 

plotting the coefficients determined from meter measurements. Tables based 

on measurements during 1912 to 1917 have been used for 1919. For 1920 one 

curve has been used for all gate openings based on meter measurements of 1921.

EXTREMES OF DISCHARGE. Maximum discharge during year ending September 30, 

-1919, 370 second-feet, head on gates 0.65 foot, 2 gates open 5.2 feet, 1 open 5.0 

feet. Minimum; canal dry beginning May 3.

1920: Maximum discharge during year ending September 30,1920, 331 secondfeet, head on gates 1.0 foot, area of orifices 55.2 square feet. Minimum; canal 

dry beginning May 9. 

1912-1920: Maximum discharge, 508 second-feet, February 28, 1914.

ACCURACY. Coefficients used in computing discharge through orifices are not well 

denned for 1919 and 1920. Gages read to half-tenths once a day, gate openings 

read to inches whenever gates are changed. Daily discharge ascertained by 

obtaining from a table the velocity for the observed head and multiplying by 

the area of gate opening in square feet. Records fair.

COOPERATION. Field data furnished by the United States Reclamation Service.

Discharge measurements of Lost River diversion canal near Olene, Oreg., during

and 1921.

SHASTA RIVER NEAR MONTAGUE, CALIF.

LOCATION. In N. £ NE. J sec. 33, T. 45 N., R. 6 W., at highway bridge 1J miles 

southwest of Montague, Siskiyou County, Little Shasta River enters 1 mile above 

and Yreka Creek 5fc miles below station.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. August 24, 1911, to September 30, 1913; September 20, 1916, 

to Septamber 30, 1929.

GAOE. Vertical staff in two sactions; lower section fastened to bridge pier on right 

bank; upper section to left abutment. Several changes in gage section have been 

made but original datum has been maintained. Gage read by Merrill and Spooner.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Small boulders and gravel; fairly permanent. Banks are 

subject to overflow during very high water.

EXTREMES OF DISCHARGE. Maximum stage recorded during year ending September 

30, 1919, 5.65 feet at 9 a.m. February 10 (discharge, 1,490 second-feet); minimum 

stage during year, 2.45 feet at 9 a.m. July 17 (discharge, 10 second-feet).

Maximum stage recorded during year ending September 30, 1920, 3.8 feet 

December 20 and 21 (discharge, 315 second-feet); minimum stage during year, 

2.2 feet 9 a.m. July 19 (discharge, 2.0 second-feet.)

1911-1920: Maximum stage recorded, 5.65 feet at 9 a.m. February 10, 1919 

(discharge, 1,490 second-feet); minimum stage, 2.1 feet April 7, 1918 (discharge, 

1.5 second-feet).

DIVERSIONS. The Dwinnell ditch diverts about 30 second-feet 2 miles above the 

gage. The Grenada ditch diverts about 40 second-feet 12 miles above the gage. 

Some water is probably returned to the river above the gage. Other small ditches 

divert above the station.

REGULATION. Considerable diurnal fluctutaion at the gage due to irrigation above.

ACCURACY. Stage-discharge relation changed December 20, 1919. Rating curves 

well defined between 10 and 400 second-feet and extended above. Gage read 

to half-tenths once daily and to hundredths occasionally. Daily discharge ascertained by applying daily gage height to rating table. Records good except 

those for irrigating season which are fair.
