SURFACE WATER SUPPLY OF PACIFIC SLOPE BASINS 

IN CALIFORNIA, 1921

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, 1921.

The data presented in these reports were collected by the United 

States Geological Survey under the following authority contained in 

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

Provided, That this officer [the Director] shall have the direction of the Geological Survey and the classification of public lands and examination of the 

geological structure, mineral resources, and products of the national domain.

The work was begun in 1888 in connection with special studies 

relating to irrigation 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 the United States 

and for the investigation of underground currents and artesian wells, and for the 

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

Annual appropriations for the fiscal years ending June SO, 1895-19%%

In the execution of the work many private and State organizations 

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

data. Acknowledgments for cooperation of the first kind are made 

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

Measurements of stream flow have been made at about 5,200 points 

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

98681 25t WSP 531 2 1
2 SURFACE WATER SUPPLY, 1921, PART XI

Hawaiian Islands. In July, 1921, 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 "run-off" or "discharge" is expressed in various terms, each of which has become 

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

into two groups (1) those that represent a rate of flow, as secondfeet, gallons per minute, 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-off in inches" is the depth to which an area would be covered if all the water flowing from it in a given period were uniformly 

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

rainfall, which is usually expressed in inches.

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

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

The following terms not in common use are here defined:

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

of gage height to discharge." ,"

" Control;" a term used to designate the 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>r-at which water ceases to flow over 

the control. , ,,

EXPLANATION OP DATA

The data presented in this^eport cover the year beginning October 

1, 1920, and ending September 30, 1921. 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. The application of the daily gage 

heights to these rating tables give the daily discharge from which 

the monthly and yearly mean discharge is computed.

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

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

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, artificial 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.
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, 

which are defined on page 2, are based.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

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

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 to1 25 per 

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

the individual measurements with reference to the mean rating curve.

The monthly means for any station may represent with high 

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

showing discharge per square mile and run-off in niches 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 hi which the annual rainfall is less than 20 inches. All figures 

representing "second-feet per square mile" and "run-off in inches"
PUBLICATIONS 5

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

caution because of possible inherent sources of error not known to 

the Survey.

Many gaging stations on streams in the irrigated areas of the 

United States are 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 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 Gee logical 

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 water, 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 1921. 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, 

Maine, 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 year 1921 

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

McClure, State engineer.

Additional funds for the maintenance of river-measurement 

stations were furnished by the State Water Commission of California. The members of the commission during the year were C. H. 

Lee, executive member, W. A. Johnstone (resigned during year) 

A. W. Mason, and J. L. Matthews; W. D. Stephens, governor; and 

W. F. McClure, State engineer. Josephine A. Patten is secretary.

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

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

All stations in Los Angeles County were maintained in cooperation 

with the Board of Supervisors; the United States Department of 

Agriculture, represented by the Forest Service through F. H. Fowler, 

district engineer; the United States Weather Bureau, through H. B. 

Hersey, meteorologist; and the United States Geological Survey. 

Los Angeles County paid all expenses of the field work except services 

furnished by the Forest Service, Weather Bureau, and Geological 

Survey. The Geological Survey supervised the work and compiled 

all field data for publication.

The stations in the Santa Ana River basin were maintained in 

cooperation with San Bernardino, Riverside, and Orange counties 

through their boards of supervisors. Substantial cooperation was 

also furnished by the Weather Bureau. The cost of installation of a 

number of the stations was paid from a special appropriation disbursed by the State water commission.

Assistance in the maintenance of gaging stations was furnished by 

the United States Forest Service, United States Weather Bureaus, 

United States Indian Service, United States Bureau of Fisheries, 

National Park Service, Los Angeles County, Volcan Land & Water 

Co., Cuyamaca Water Co., Southern California Edison Co., San 

Diego Consolidated Gas & Electric Co., and Turlock, Modesto, Oakdale, South San Joaquin/ and Madera irrigation districts.
10 . SURFACE WATER SUPPLY, 1921, PART xi

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

private companies, and -individuals who are interested in the water 

resources of California. This cooperation is acknowledged and 

 explained in the descriptions that precede the records.

The work in Oregon was carried on under a cooperative agreement 

with the State through Percy A. Cupper, 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, R. C. Briggs, C. J. Emerson, 

K. M. Kelley, Jarrett Oliver, H. C. Troxell, Jesse Arnold, and H. J. 

Tompkins.

The field work in Oregon was carried on under the direction of 

F. F. Henshaw, district engineer, by J. W. Bones, R. C. Briggs, 

Wendell Dawson, and K. N. Phillips, and by Ted Cole, hydrographer 

of the United States Bureau of Reclamation. The ratings, special 

estimates, and computations were made and data prepared for publication by F. F. Henshaw, district engineer, assisted by G. H. Canfield, K. N. Phillips, and Wendell Dawson.

The manuscript was reviewed and assembled by J. J. Dirzulaitis.

GAGING-STATION RECORDS

SWEETWATEB RIVER BASIN

SWEETWATEE EIVEE NEAR DESCANSO, CALIF.

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

mouth of Guatay Creek and 1J^ miles below Descanso, San Diego County.

DRAINAGE AREA. 43.7 square miles (measured on topographic maps).

RECORDS AVAILABLE. November 21, 1905., to September 30, 1921.'

GAGE. Staff in three sections on left bank a short distance below intake of Ellis 

ditch. On November 6, 1918, a new staff was installed at a new datum 

at new concrete control below old gage. Previous gages were at approximately the same location but at different datums. Read by Henry D. 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 about 125 feet below gage acts as a partial control. On November 

6, 1918, a concrete control was built at this location.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 2.24 feet 

November 5 (discharge, 12 second-feet); minimum stage, 1.30 feet August 

7 (discharge, 0.1 second-foot).

1905-1921: Maximum stage not known, occurred January 27, 1916 

(discharge, about 9,870 second-feet); stream dry during a part of the years 

1910, 1911, 1913, and 1916.
SW1ETWATER ETVER BASIN

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

Ellis ranch.

REGULATION. None.

ACCURACY. Stage-discharge relation not permanent. Eating curve fairly well 

defined. Gage read to hundredths twice a day. Daily discharge ascertained by applying mean daily gage height to rating, curve except January 18 

to February 12 and March 12-22, when shifting-control method was used. 

Records good.

SAN DIEGO RIVER BASIN

SAN DIEGO RIVER NEAR SANTEE, CALIF.

LOCATION. At Loop dam site, 6 miles west of Santee, San Diego County.

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

at old Mission dam.

RECORDS AVAILABLE. May 25, 1912, to September 30, 1921 (record not complete) .

GAGE. Water-stage recorder on right bank at Loop dam site, 1J^ miles below 

old Mission dam. Station moved downstream November 20, 1920.

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

CHANNEL AND CONTROL. Solid rock formation forces ground water above dam 

to surface. The old Loop dam serves as part control.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 0.53 foot at 

10 a. m. March 14 (discharge, 15 second-feet); ground water rising to 

surface estimated as 0.1 second-foot during summer months.

1912-1921: Maximum stage recorded, 25.1 feet January 27, 1916 (discharge, 70,200 second-feet); stream practically dry for several months each 

year except for a small amount of ground water being forced to surface.

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 permanent. Rating curve fairly well defined by two discharge measurements and six estimates of discharge. Waterstage recorder installed November 10 and removed June 6. Recorder record 

excellent. Daily discharge ascertained by applying mean daily gage height 

to rating table. The discharge was probably very small on all days when 

gage was not in operation and has been estimated as 0.1 second-foot steady 

flow. Records fair.

COOPERATION. Gage-height record obtained in cooperation with Cuyamaca 

Water Co., Ed Fletcher, manager.

BOULDER CHEEK 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, 1921.

GAGE. Vertical staff on right side of weir box, 3J^ 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.
14 SURFACE WATER SUPPLY, 1921, PART XI

CONTBOL. Cippoletti weir acts as permanent control.

EXTREMES OF DISCHARGE. Maximum mean daily discharge during year, 13.5 

second-feet May 13; stream dry several months during year.

1912-1921: Maximum mean daily discharge, 1,877 second-feet January 

28, 1916. 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 41J^ feet 

high, with an inner slope of 2:1 and an outer slope of 1^: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. Rating curve well defined. 

Gage read daily to hundredths; additional observations are made when 

reservoir gates are changed. Records excellent.

COOPERATION. Gage-height record and measurements furnished by Cuyamaca 

Water Co.

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

LOCATION. In SE. 3 sec. 11, T. 14 S., R. 2 E., just below intake, at diverting 

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

RECORDS AVAILABLE. June 1, 1912, to September 30, 1921.

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 7-14r 

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 Cuyamaea Water Co.

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

CHANNEL AND <5dNTROL. The flume is lined with tar paper to reduce leakage.

EXTREMES OF DISCHARGE. 1912-1921: Maximum daily discharge, 51 secondfeet, March 24, 1913. No flow for periods nearly every year.

ACCURACY. Stage-discharge relation permanent. Rating curve fairly well defined. Gage read to hundredths three times daily except for a few days 

when it was read only twice. Daily discharge ascertained by applying 

mean daily gage height to rating table. Records fair.

COOPERATION. Gage-height record and discharge measurements furnished by 

Cuyamaea Water Co.

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

receives water from the South Fork of San Diego River, is 6 feet wide, and 24 

inches deep, and more than 30 miles long. 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 irrgiation and 

domestic service. The Capitan Grande Indian Reservation has a water right 

of 0.8 second-foot from this fltnne.

same as elevation of floor of flume. Gage read by an employee of Cuyamaca Water Co.

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

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

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

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

made December 7-19, 1918.

EXTREMES OP DISCHARGE. 1907-1921: Maximum mean daily discharge, 25 

second-feet February 16, 1918. No flow at times nearly every year.

ACCURACY. -Stage-discharge relation changed January 18 and April 15. Two 

fairly well defined rating curves were used during year. Gage read to 

hundredths three times daily except for several days when it was read 

twice. Daily discharge ascertained by applying mean daily gage height to 

rating table. Records fair.

COOPERATION. Gage-height record and some measurements 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.

SAN DIEGUITO RIVER BASIN

SANTA ISABEL CREEK NEAR MESA GRANDE, CALIF.

LOCATION. In NW. \^ sec. 21, T. 12 S., R. 2 E., at Sutherland dam site, 1 mile 

below Sutherland, 1J^ miles above mouth of Black Canyon Creek, .and 

4J^ miles southwest of Mesa Grande, San Diego County.

DRAINAGE AREA. 53.4 square miles (measured on topographic map).
SAljT DIEGUITO EI7EE BASIN 21

RECORDS AVAILABLE. December 29, 1912, to September 30, 1921.

GAGE. Water-stage recorder on right bank just above Sutherland dam site. 

Gage datum was lowered 0.21 foot on October 12, 1916, on account of change 

in control. Previous gages have been at same location but original datum 

has not been maintained.

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

CHANNEL AND CONTROL. Bed is shifting sand. A concrete control has been 

constructed at an outcropping of bedrock 20 feet below gage. This control 

was repaired November 6-9, 1916. Banks are high, i covered with brush, 

and not subject to overflow.

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

recorder, 2.12 feet at 1 p. m. March 14 (discharge, 68 second-feet); no flow 

July 6-14 and July 23 to September 30.

1912-1921: Maximum stage recorded, 11.0 feet January 27, 1916 (discharge, 21,100 second-feet); stream dry October 1-2, 1913; August 12-29, 

September 6-13, 1914; July 6-14 and July 23 to September 30, 1921.

DIVERSIONS. No large diversions above the station.

REGULATION. None.

ACCURACY. Stage-discharge relation at low stages changes frequently owing to 

sand collecting on control. Standard rating curve is well defined by 61 

discharge measurements. The operation of the water-stage recorder was 

satisfactory throughout the year. Daily discharge ascertained by applying 

mean daily gage height to rating table or by shifting-control method. 

Records good.

GAGE. Water-stage recorder on left bank at dam site used during fluctuating 

stages. A vertical staff fastened to outside of gage well used during re 

mainder of year. Gage read by C. M. DeVenelle. Original gage was a staff 

in four sections on left bank, one-half mile up stream, with a short vertical 

section at concrete control.

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

by wading.
SAN DIEGUITO MVEB BASIN

CHANNEL AND CONTROL. Shifting sand. Banks are high and clean; channel 

straight for 200 feet above and 600 feet below gage. Concrete control 

built across channel just below gage was completed December 8, 1916, 

and was destroyed by the high water on March 12, 1918.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 2.60 feet at 

2 p. m. March 14 (discharge, 122 second-feet); stream practically dry during July, August, and September.

1912-1921: Maximum stage recorded, 14.0 feet January 27, 1916 (discharge, 28,400 second-feet); stream practically dry July, August, and September, 1921.

DIVERSIONS. 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 the East San Pasqual ditch.

RE GTTL ATIO N . None.

ACCURACY. Stage»-discharge relation changed frequently. Staff gage read to 

hundredths twice daily. Water-stage recorder in operation January 2 to 

September 30. Two well-defined rating curves used January 18 to March 

11 and March 13-27. Daily discharge for these periods ascertained by applying mean daily gage height to rating table, and for other periods by 

reading direct from curves or by shifting-control method. During low 

water discharge was ascertained mainly by interpolation between discharge 

measurements. Records fair.

ESCONDIDO MUTUAL WATER CO.'S CANAL NEAR NELLIE, CALIF.

LOCATION. In SW. % NW. Y± sec. 33, T. 10 S., R. 1 E., 500 feet below intake

on San Luis Rey River, 3J^ miles above Rincon Indian Reservation, 5

miles southwest of Nellie, San Diego County, and 15 miles northeast of

Escondido. 

RECORDS AVAILABLE. October 1, 1896, to September 30, 1921, except that there

are no records for the years 1901-2 and 1903-4.

GAGE. Enameled vertical staff indicating depth of water on crest of weir. 

DISCHARGE MEASUREMENTS. Made from plank across canal or by wading at

various sections near gage. 

CONTROL. Rectangular weir with steel plate crest 6 feet long in concrete slab,

500 feet below intake. October 29, 1915, wooden weir board was replaced

by concrete slab with steel plate for crest. Length of crest not changed.

March, 1916, Mr. E. R. Bowen installed a weir at south portal of tunnel No.

2 and developed rating curves for the various crude weirs which had been

used in previous years. 

COOPERATION. Daily-discharge record furnished by Escondido Mutual Water

Co.; computed from weir table. Monthly discharge computed by United

States Geological Survey.

The canal is 5,6 miles long; consists of flume, ditch, and tunnel sections 

constructed through a very rough, mountainous country. It discharges into a 

reservoir about 6 miles northeast of Escondido. The dam is 76 feet high and 

380 feet long, is of the usual rock-fill type, and is faced with redwood planks. 

The reservoir (capacity, 3,120 acre-feet) supplies water for irrigation and domestic uses at Escondido and vicinity.

No discharge measurements during the year.

SURFACE WATER SUPPLY, 1921, PABT XI

SANTA ANA RIVER BASIN

SANTA ANA BITER NEAR MENTONE, CALIF.

LOCATION. In SW. ^ sec. 4, T. 1 S., R. 2 W., near mouth of canyon, onefourth mile above Southern California Edison Co.'s power plant, half a 

mile above mouth of Deep Creek, and SJHa miles northeast of Mentone, San 

Bernardino County.

DRAINAGE AREA. 189 square miles (measured on topographic map).

RECORDS AVAILABLE. July 1, 1896, to September 30, 1921.

GAGE. Water-stage recorder, in concrete well and shelter, installed September 7, 

1917, on left bank at rock ledge one-fourth mile above power house, at same 

location and datum as vertical staff installed February 11, 1916. Previous 

staff, destroyed by the flood of January, 1916, was 10 feet upstream at an 

independent datum. Original gage was just above Warm Springs Canyon, 

IJHa miles upstream.

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

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

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

recorder, 4.20 feet at 6 a. m. March 14 (discharge, 1,100 second-feet); 

minimum stage, 0.72 foot January 26 (discharge, 1.1 second-feet).

1896-1921: Maximum discharge (stage not known, gage washed out), 

29,100 second-feet January 27, 1916, computed from cross-section and slope; 

minimum stage 0.44 foot at 1 a. m. October 12, 1919 (discharge estimated, 

0.1 second-foot).

DIVERSION. Water is diverted at Southern California Edison Co.'s plant 

No. 2, 2j^ miles above gage for use at Mentone power house. The Greenspot 

pipe line diverts water for irrigation from the forebay at Mentone power 

house. From the tailrace the water is carried across Santa Ana River and 

used for irrigation.

REGULATION. Water is stored on Bear Creek at Bear Valley reservoir. Southern 

California Edison Co.'s power plants Nos. 1 and 2 are 5*4, and 2% miles, 

respectively, above the Mentone plant, at the mouth of the canyon. Capacity of Big Bear reservoir is 65,065 acre-feet.

ACCURACY. Stage-discharge relation not permanent. Rating curves fairly well 

defined. Recorder operated satisfactorily. Daily discharge ascertained by 

applying mean daily gage height to rating table. Records good.

SANTA ANA BIVEE NEAR PR ADO, CALIF.

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

(unsurveyed), 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, 192?.
38 SURFACE WATER SUPPLY, 1921, PART XI

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

at county line.

DISCHAKGE MEASUKEMENTS. Made from cable 500 feet above gage. At low 

stages measurements are made from temporary footbridge at cable or by 

wading.

CHANNEL AND CONTKOL. Bed consists of sand; shifting.' Banks are low and 

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

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

brush along bank of low-water channel.

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

recorder, 5.60 feet at 5 p. m. March 14 (discharge, about 2,900 second-feet); 

minimum stage, 1.12 feet at 10 p. m. July 17 (discharge, 60 second-feet).

1919-1921: Maximum stage from water-stage recorder, 5.45 feet at 

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

stage from water-stage recorder, 1.21 feet at 8 p. m. July 15, 1919 (discharge, 

41 second-feet).

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

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

out of underground storage by flowing wells and pumping plants.

REGULATION. Storage has been developed at 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 Jacinto River basin and discharges 

into Temescal Creek only during seasons of very high run-off. (See Lake 

Elsinore at Elsinore p. 67).

ACCURACY. Stage-discharge relation continually changing. Five fairly well 

defined curves used during year. Operation of 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, by shifting-control method, and by interpolation between measurements. Records are good.

For comparative purposes, discharge measurements were made on the same 

day during the irrigating season at various points in the lower Santa Ana River 

drainage basin. Measurements were also made at some of these points during 

the irrigating season of 1919 and 1920. The results of these measurements are 

given in the following table.

SOUTHEBH CALIFORNIA EDISON CO.'S CANAL AND GEEENSPOT FIFE LINE HEAR MENTONE,

CALIF.

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

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

of Mentone, San Bernardino County. 

RECOBDS AVAILABLE. 1896 to September 30, 1921.

DISCHARGE. Canal discharge computed from records showing kilowatt output 

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

Records furnished by power company.

EXTREMES OP DISCHARGE. 1896-1921: 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.

ACCTJBACY. The record for power canal is computed on the assumption that 1

second-foot develops 18.9 kilowatts. The weir record for the pipe line is

considered good.

COOPEBATION. 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 line, is first used for 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 passes through 

three power plants.

MHL CREEK NEAR CRAFTONVUXE, CALIF.

LOCATION. In NE. }^ sec. 13, T. 1 S., R. 2 W.,at mouth of canyon, on RedlandsBear Valley highway, 5% miles northeast of Craftonville, San Bernardino 

County.

DRAINAGE AREA. Not measured.

RECOBDS AVAILABLE. January 21, 1919, to September 30, 1921.

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

Edison Co.'s concrete diversion dam.

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 OF DISCHARGE. Maximum stage during year from water-stage 

recorder, 0.90 foot at 6 a. m. March 14 (discharge, from extension of rating 

curve, about 280 second-feet); all water diverted into Mill Creek power 

canal No. 1 at various times during year.

1919-1921: Maximum stage recorded, 2.00 feet February 22, 1920 (discharge, about 650 second-feet); all water diverted into Mill Creek power 

canal No. 1 at various times.

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

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

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

2 and 3 lead to power plants No. 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 furnish sufficient water for plant No. 1.

ACCURACY. Stage-discharge relation not permanent. Rating curves fairly well 

defined. Water-stage recorder operated part of time. Daily discharge 

ascertained by applying mean daily gage height to rating tables, interpolating 

between measurements, estimated by employees of Southern California
SANTA ANA EIVEB BASIN 45

Edison Co., or by measurements over weir in Mill Creek power canal No. 1. 

Combined daily discharge of creek and canals is the sum of the flow in creek, 

in power canal No. 1, and power canal No. 2 and 3 (see p. 47 for record of 

flow in canals). Records fair.

COOPERATION. Water-stage recorder attended by electrician of Southern 

California Edison Co.

PLUNGE CREEK NEAR EAST HIGHLANDS, CALIF.

LOCATION. In NE. J^ sec. 1, T. 1 S., R. 3 W., at mouth of canyon at crossing of 

North Fork ditch siphon, 2 miles northeast of East Highlands, San 

Bernardino County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. January 26, 1919, to September 30, 1921.

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

about 10 feet above siphon.

DISCHARGE MEASUREMENTS. Made by wading.

CHANNEL AND CONTROL. Bed composed of gravel and boulders; shifting. 

Control is section of abandoned steel pipe line filled with sand, and gravel 

and imbedded in channel. Right bank high; left bank is overflowed during 

extreme floods.

EXTREMES OP DISCHARGE. Maximum stage during year from water-stage recorder, 3.15 feet at 4 a. m. March 14 (discharge, 1,100 second-feet); no 

flow for several months during year.

1919-1921: Maximum stage, from water-stage recorder, 3.15 feet at 

4 a. m. March 14, 1921 (discharge, 1,100 second-feet); no flow for several 

months during each year.

DIVERSIONS. The East Highlands Orange Co. controls Plunge Creek water 

and diverts at several points, from 2 to 5 miles above station. A small 

quantity of water is diverted about 200 feet above gage, which is wasted 

back into creek just below control when not needed for irrigation.

REGULATION. None.

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

rating curves used during year. The water-stage recorder operated satisfactorily. Daily discharge ascertained by applying to rating table mean 

daily gage height determined by inspecting water-stage recorder graph. 

Records fair.

ELSINORE LAKE AT ELSINORE, CALIF.

LOCATION. A short distance southeast of outlet at Elsinore, Riverside County.

RECOKDS AVAILABLE. December 1, 1915, to September 30, 1921.

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.

Elsinore Lake overflows only during and after years of heavy rainfall. Temescal Creek is the high-water outlet for the lake. The heavy rains during the 

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.

always in place. Weirs are 1.6 feet long. All water may be diverted into

one pipe line by addition of flashboards on one weir. 

EXTREMES OF DISCHARGE. Maximum mean daily discharge recorded during

the period, 9.4 second-feet July 13. No water is diverted at times. 

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

Water-stage recorder stopped November 28 to December 12 and September

10-30, 1921. Daily discharge ascertained by applying mean daily gage

height to rating table and interpolating when recorder was not in operation.

Records good.

76 SURFACE WATER SUPPLY, 1921, PART XI

SAN GABRIEL RIVER BASIN

SAW GABRIEL RIVER NEAR AZTTSA, CA1IF.

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

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

and 2 miles north of Azusa, Los Angeles County.

DRAINAGE AREA. 222 square miles.

RECORDS AVAILABLE. 1894 to September 30, 1921.

GAGE. 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 near gage.

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

EXTREMES OF DISCHARGE. Maximum stage during year, from flood marks, 7.45 

feet March 14 (discharge, 4,000 second-feet); stream dry at gage several 

times during year.

1894-1921: 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 station. Water was diverted through the tunnel about 

500 feet above ford at various times. (For daily discharge of these canals 

see pp. 78-81.)

REGULATION. None.

ACCURACY. Stage-discharge relation not permanent throughout year. Rating 

curves well defined. Operation of water-stage recorder satisfactory. Daily 

discharge ascertained by applying to rating table mean daily gage height 

determined by inspecting recorder graph. Records good.

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. 87.)

REGULATION. None.

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

Water-stage recorder operated satisfactorily. Daily discharge ascertained 

by applying to rating table mean daily gage height determined by inspecting 

recorder graph. Records excellent.

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

MONROVIA PIPE LINE NEAR HOKROVIA, CAIIF.

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

settling reservoir at mouth of Sawpit Canyon and 1H miles north of Monrovia, Los Angeles County.

RECORDS AVAILABLE. May 18, 1916, to September 30, 1921.

GAGE. Vertical staff in weir box; read by Armstrong and Pratt, canyon guards.

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 OF DISCHARGE. Maximum mean daily discharge, 3.7 second-feet 

March 16 and 17; minimum mean daily discharge, 0.6 second-foot September 21-29.

1916-1921: Maximum mean daily discharge recorded, 5.0 second-feet 

May 18 and 19, 1916; minimum mean daily discharge recorded, 0.6 secondfoot September 21-29, 1921.

ACCURACY. Stage-discharge relation permanent. 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.

SAW DIMAS CREEK WEAR SAW DIMAS, CALIF.

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

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

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

RECORDS AVAILABLE. December 3, 1916, to September 30, 1921. (Discharge 

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

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

of canyon just above concrete control.
SURFACE WATER SUPPLY, 1921, PART XI

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

wading.

OHANNEL AND CONTBOL. 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. During 1921 a wooden dam 

about 2^2 feet high was built on the control. It has a notch in it, in which 

are placed flashboards to raise water so it can be diverted through a 12-inch 

pipe. 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.

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

recorder, 7.70 feet at 12.30 a. m. March 14 (discharge, about 800 secondfeet) ; no flow October 1-6 and August 20 to September 30.

1916-1921: Maximum stage, from water-stage recorder, 6.15 feet at 1.30 

a. m. March 2, 1920 (discharge from extension of rating curve, 1,010 secondfeet) ; stream dry during a part of October and November, 1916, September, 

1919, and August and September, 1921.

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

pipe line at the dam.

ACCURACY. Stage-discharge relation changed when flashboards in notch in dam 

were placed or removed. Rating curves for various conditions are fairly 

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

Daily discharge ascertained by applying mean daily gage height to rating 

table, except March 13 and 14 when hourly discharge was averaged. Records 

good.

90 SURFACE WATER SUPPLY, 1921, PART XI

DAITON CREEK NEAR GIENDORA, CALIF.

LOCATION. At 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, 1921.

GAGE. Water-stage recorder in concrete well and shelter 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 OF DISCHARGE. Maximum stage during year from water-stage recorder, 3.00 feet at 1.10 a. m. March 14 (discharge, 294 second-feet); no 

flow October 1-29, November 4, 10, 11, 14, February 11-13, June 21-27, 

and July 7 to September 30.

1919-1921: Maximum stage from water-stage recorder, 4.03 feet at 12.45 

a. m. March 2, 1920 (discharge, 525 second-feet); no flow for several months 

during each year.

DIVERSIONS. The Glendora Irrigation Co. diverts water half a mile and 1% 

miles above the gage through a 10-inch pipe line. A 12-inch pipe line 

diverts water at the control. No record of amount diverted was kept for 

this year, except for some miscellaneous measurements; page 294.

REGULATION. None.

ACCURACY. Stage-discharge relation changes due to silt collecting on the control. Rating curves well defined. Drainage area was burned over during 

1919 and excessive erosion during rainy season brought down an unusual 

amount of silt. Water-stage recorder operated satisfactorily throughout 

year. Daily discharge ascertained by applying mean daily gage height to 

rating table. Records good.

LOS ANGELES RIVER BASIN

PACOIMA CREEK NEAR SAN FERNANDO, CALIF.

LOCATION. In SE. ^ NE. M sec. 24, T. 3 N., R. 15 W., 600 feet above mouth of 

canyon 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, 1921 (not complete).

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

December 2, 1916. Previous gage was a staff fastened to 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 brush and trees. Control is a low boulder and concrete dam 

built across channel about 7 feet below gage.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 3.73 feet at 10 p. m. May 21 (discharge, 440 second-feet); 

no flow September 27 and 28.

1916-1921: Maximum stage recorded, 4.68 feet December 24, 1916 

(discharge, 1,440 second-feet); usually no flow during part of each year.

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

REGULATION. None.

ACCURACY. Stage-discharge relation not permanent on account of shifting 

deposits of sand at control. The entire drainage area was burned over during 

September, 1919, and more than the usual amount of debris was brought 

down. Several well defined rating curves were used. Water-stage recorder 

operated satisfactorily except May 22 and 23 when discharge was estimated 

from flow of Tujunga Creek. Daily discharge ascertained by applying to 

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

Records good.

stage, 0.50 foot August^ 23 and September 26-29 (discharge, 0.5 secondfoot).

1916-1921: Maximum stage recorded, 3.35 feet December 24, 1916 (discharge, from revised rating curve defined by measurements in 1918, 1,960 

second-feet); minimum stage not known (discharge estimated as 0.1 secondfoot, September 20-23, 1919).

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

irrigation above the station. f There are two small diversions between gage 

and mouth of canyon.

REGULATION. None.

ACCURACY. Stage-discharge relation not permanent due to sand collecting at 

control; changed from that of last .year. Rating curve well defined below 

400 second-feet. Operation of the water-stage recorder satisfactory except 

for period October 27 to November 4 and April 8-22. Daily discharge 

ascertained by applying to rating table mean daily gage height determined 

by inspecting recorder graph. Records good.

HAIWES CHEEK NEAR TUJUNGA, CALIF.

LOCATION. In NE. M NE. M 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, 1921.

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

DISCHARGE MEASUREMENTS. Made by volumetric method when discharge is 

very small, or by wading on crest of dam. A gaging bridge, for use during 

high water, is 4 feet above dam. -»
96 SUEFACE WATER SUPPLY, 1921, PART XI

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

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

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

channel at downstream face of gage well. A 12-foot concrete wing wall was 

constructed at left end of dam. Crest of dam has a trapezoidal notch 6 

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

for low stages. Zero flow, gage height about 0.25 foot.

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

recorder, 1.15 feet at 8 p. m. May 21 (discharge, 3.8 second-feet); stream 

dry July 18 to August 1.

1917-1921: Maximum stage recorded, 1.37 feet March 10, 1918 (discharge, 

6.8 second-feet); stream dry July 18 to August 1, 1921.

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. A fragmentary 

record of upper diversion is given on page 97. 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 well defined. 

Operation of water-stage recorder satisfactory throughout year. Daily 

discharge ascertained by applying to rating table mean daily gage height 

determined by inspecting gage-height graph. Records good.

The following discharge measurement was made by H. J. Tompkins: 

May 21, 1921: Gage height, 1.02 feet; discharge, 2.5 second-feet, j

118 SURFACE WATER SUPPLY, 1921, PART XI

KERN RIVER BASIN 

KEEN RIVER NEAR KERNVILIE, CALIF.

LOCATION. In SE. % sec. 14, T. 23 S., R. 32 E., at base of Fairview Mountain, 

1 mile below intake of Kern River No. 3 canal, in Tulare County, in Kern 

National Forest, 3 miles above Salmon Creek, and 15 miles north of Kernville, Kern County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. January 1, 1912, to September 30, 1921.

GAGE. Water-stage recorder on left bank 1 mile above mouth of Tobias Creek. 

Original gage was vertical staff in three sections fastened to overhanging 

willow tree on left bank 160 feet above recorder. From April 1 to September 

14, 1913, readings were taken from a temporary staff in two sections located 

one-fourth mile upstream. The readings were reduced to the original datum 

by a relation 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 and at the same datum.

DISCHARGE MEASUREMENTS. Made from cable 90 feet below recorder or by 

wading.

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

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

recorder, 3.98 feet at 8 a. m. June 8 (discharge, 3,000 second-feet); minimum

stage, 0.70 foot at the dam at 6 a. m. July 27 (discharge, 0.4 second-foot).

1912-1921: Maximum stage recorded, 8.8 feet, from water-stage recorder,

 at 4 p. m. January 17, 1916 (discharge, 9,690 second-feet); minimum stage,

 0.70 foot at the dam at 6 a. m. July 27, 1921 (discharge, 0.4 second-feet).

DIVERSIONS. Kern River No. 3 canal diverts water for power about 1 mile above 

station. The water is returned to the river at the power house about 8 miles 

below station.

REGULATION. Complete regulation by the canal at stages below capacity of 

canal.

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

Water-stage recorder operated satisfactorily to July 12 when water fell below 

intake pipe. Staff gage on dam read frequently during day, July 13 to 

August 6; staff gage at recorder read once daily August 7 to September 30. 

Daily discharge ascertained by applying mean daily gage height to rating 

table except July 14-21 and July 26 to August 6, when discharge was ascertained by applying mean daily gage height at the dam to rating table developed for the dam. Records good.

COOPERATION. Station maintained in cooperation with Southern California 

Edison Co. through H. W. Dennis, construction engineer.

DISCHARGE MEASUREMENTS. Made from cable 1J^ miles below gage or by 

wading.

CHANNEL AND CONTROL. Rough; boulders and gravel; shift slightly during 

high water. Banks high and not subject to overflow.

EXTREMES OP DISCHARGE. Maximum stage uncertain owing to poor gage readings; minimum stage recorded 0.8 foot August 18-26 (discharge, 2.6 secondfeet).

1910-1921: Maximum stage recorded, 8 feet at 8 a. m. January 26, 1914 

(discharge, determined from extension of rating curve, about 2,750 secondfeet); minimum stage, 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 March 14. Rating curve for 

temporary gage below pump house fairly well defined; curve for gage above 

pump house well defined. Gage apparently read occasionally from October 

1 to May 9; read to half-tenths once daily May 10 to September 30. Daily 

discharge not ascertained for period October 1 to April 30. Daily discharge 

ascertained by applying gage height to rating table. Mean monthly discharge for months October to April estimated from flow of Tule River and 

from flow on certain days when record appeared reliable. Records poor 

October to May and fair June to September.

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

miles southwest of Three Rivers, Tulare County. S South Fork enters threefourths of a mile above station and North Fork 3 miles above.

DRAINAGE AREA. 520 square miles.

RECORDS AVAILABLE. April 29, 1903, to September 30, 1921.

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 Vickroy 

and Nice. Water-stage recorders were used from! March 29 to August 7 

at same site as staff gage. 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.

September 3-5, 10-16, 20, and October 17-19, 1919 (discharge, 26 secondfeet).

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 second-feet.

REGULATION. Power is developed on the Middle and East forks but effect is 

thought to be small.

ACCURACY. Stage-discharge relation changed June 10. Rating curves well 

defined between 40 and 4,000 second-feet; extended above. Gage read to 

half-tenths twice daily. Water-stage recorder record used March 29 to 

August 7. Daily discharge ascertained by applying mean daily gage height 

to rating table. Records poor, October 1 to March 28 owing to unreliability

KAWEAH RIVER AT McEAY POINT, NEAR LEMON COVE, CALIF.

LOCATION. On 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 July 7, 1921.

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.

DIVERSIONS. 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 

acre-feet. 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.

LOCATION. In NW. % sec. 5, T. 11 S., R. 21 E., 1^ miles northeast of Friant, 

Fresno County.

DRAINAGE AREA. 1,640 square miles at old location 2 miles upstream.

RECORDS AVAILABLE. October 18, 1907, to September 30, 1921.

GAGE. Water-stage recorder on left bank, installed December 9, 1913. Previous to that date a staff gage located on left bank in SE. J sec. 34, T. 10 S., 

R. 21 E.,, 4 miles northeast of Friant, was used.

DISCHARGE MEASUREMENTS. Made from cable 300 feet below gage or by wading.

CHANNEL AND CONTROL. Bed consists of sand and gravel. Control is a solid 

rock dyke about 500 feet below gage.

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

recorder, 13.08 feet at 8 a. m. June 12 (discharge, 15,300 second-feet); minimum stage from water-stage recorder, 3.01 feet at 3 a. m. September 12 

(discharge, 162 second-feet).

1907-1921: Maximum stage recorded, 21.72 feet at 11.30 p. m. January 25, 

1914 (discharge, from extension of rating curve, about 46,200 second-feet); 

minimum stage from water-stage recorder 2.67 feet from 6 a. m. to 10 p. m. 

September 27, 1920 (discharge, 98 second-feet); stage was probably lower as 

instrument could not record below 2.67 feet as float rested on bottom of well.

between 240 and 16,000 second-feet and extended above. Water-stage 

recorder stopped November 25 to February 20. Mean daily gage height 

determined by averaging readings printed every 15 minutes by the 

water-stage recorder. Daily discharge ascertained by applying mean daily 

gage height to rating table. Discharge for periods of no record determined 

by comparison with records of flow of Kings River near Sanger and the 

Weather Bureau gage heights at Friant. Records excellent except for 

estimated periods which are fair.

a Estimated from records of flow of Kings River near Sanger and the Weather Bureau gage-height records 

of San Joaquin River at Friant.

SAN JOAQUIN RIVER HEAR NEWMAN, CAUF.

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

road, 300 feet below mouth of Merced River and 3J^ miles northeast of

Newman, Stanislaus County. 

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. April 29, 1912, to September 30, 1921. 

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

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

Lorensen.

DISCHARGE MEASUREMENTS. Made from bridge or by wading. 

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

Banks subject to overflow.
140 SURFACE WATER SUPPLY, 1921, PART XI

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 12.5 feet

at 7 a. m. January 20 (discharge, 9,200 second-feet); minimum stage 1.45

feet October 1 and 2 (discharge, 58 second-feet).

1912-1921: Maximum stage recorded, 18.0 feet at 9 a. m. January 27,

1914 (discharge, 20,700 second-feet); minimum stage 1 foot October 5 and

8 to 18, 1913 (discharge, 50 second-feet). 

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

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

amount of return water. 

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

Creek, at Crane Valley reservoir on North Fork Creek. 

ACCURACY. Stage-discharge relation changed December, 13, March 5, and

June 6. Rating curves well defined except for period December 14 to

March 5 which is fairly well defined. Gage read to half-tenths once daily.

Daily discharge ascertained by applying gage height to rating table except

March 6 to April 3 when shifting-control method was used. Records good.

FRESNO RIVER BASIN 

FEESNO BIVEB NEAE KNOWLES, CAUF.

LOCATION. In N. J^ sec. 15, T. 8 S., R. 20 E., at Fresno Crossing, 6 miles 

northeast of Knowles, Madera County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. September 16, 1911, to January 1, 1914, and November 

13, 1915, to September 30, 1921.

GAGE. Vertical staff in two sections; low-water section on left bank about 60 

feet above bridge; high-water section on right bank about 100 feet above 

bridge. There have been several changes in gage sections but the original 

datum probably has been maintained. Gage read by J. E. Gayman.

DISCHARGE MEASUREMENTS. Made from cable about 300 feet below bridge 

or by wading.

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

outcroppings of bedrock; fairly permanent. A concrete control was installed November 4, 1916.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 3.60 feet 

at 4.30 p. m. January 18 (discharge, determined from extension of rating 

curve, about 1,740 second-feet); minimum stage, 0.50 foot August 31 and 

September 1 (discharge, 1.0 second-foot).

1911-1914 and 1916-1921: Maximum stage recorded, 6.0 feet at 5 p. m. 

February 21, 1917 (discharge, determined from extension of rating curve, 

about 4,500 second-feet); no flow part of August and September, 1919.

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

REGULATION. Diurnal fluctuation at low stages due to diversions above.

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

below 400 second-feet and extended above. Gage read to hundredths 

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

table. Records good except those for high water which are fair.

MERCED RIVER AT MILIKEN BRIDGE, NEAR NEWMAN, CALIF.

LOCATION. At concrete highway bridge 7 miles above Newman, Stanislaus 

County.

RECORDS AVAILABLE. March 18 to August 31, 1921.

GAGE. Staff gage on left bank just below bridge.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Shifting sand; control is a stretch of the river. Backwater from high stages on San Joaquin River affects stage-discharge relation.

DIVERSIONS. Practically all the water of Merced River is diverted above the 

station. The records show the amount of water going to waste during 

high stages and the amount of return water from irrigation during low 

stages.

REGULATION. See preceding paragraph.

ACCURACY. Stage-discharge relation not permanent. Rating curves fairly well 

defined. Gage read to half-tenths twice daily. Daily discharge ascertained 

by applying mean daily gage height to rating table except June 9-28 when 

shifting-control method was used. Records good.

TUOLUMNE RIVER ABOVE IA GRANGE DAM, NEAR LA GEANGE, CALIF.

LOCATION. In NE. 34 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, 1921.

GAGE. Water-stage recorder on left bank 1 mile below Don Pedro dam (in 

course of construction).

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 dyke which extends 

entirely across 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 not recorded but flow 

over the La Grange dam was about 25,000 second-feet, at 7 a. m. January 

18; minimum stage, from water-stage recorder, 2.27 feet from 12.30 to 

5.15 p. m. October 5 (discharge, 76 second-feet).

1916-1921: 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 & San Francisco Power Co.'s canal heads 9^ miles above 

the station and returns its water half a mile above the bridge at La Grange, 

except during irrigation season, when.the water is not used for power but 

is 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 irrigation in vicinity of Groveland.

REGULATION. None.

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

Water-stage recorder stopped frequently during year due to various causes. 

Mean daily gage height determined by averaging gage heights printed 

every hour by the water-stage recorder. Daily discharge ascertained by 

applying mean daily gage height to rating table. Discharge for periods 

when water-stage recorder was stopped estimated from flow of river at 

Buck Meadows and flow over La Grange dam. Records excellent except 

estimated periods which are fair.

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 shift 

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.

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 except for a few short periods from January to March. 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 6 and September 2, when hourly discharge was averaged. Records excellent except those for extreme low water 

which are considered good.

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 vicinity of Groveland.

REGULATION. A small amount of storage is developed at Harden ranch.

ACCURACY. Stage-discharge relation changed June 11-30 when muck from the 

tunnels above gage was washed down by high water and deposited on control. 

Rating curve before change well defined; curve after change poorly defined. 

Mean daily gage height determined by inspecting recorder graph. Daily 

discharge ascertained by applying daily gage height to rating table except 

January 17 and 18 when hourly discharge was averaged. Records good 

October 1 to June 11 and poor June 12 to September 30.

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

LOCATION. In SW. J4 sec. 16, T. 3 S., R. 14 E., at short flume opposite La 

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

1J4 miles northeast of La Grange, Stanislaus County, and 13^ miles below 

intake on Tuolumne River.

RECORDS AVAILABLE. 1908 to September 30, 1921 (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.
168 SUEFACE WATER SUPPLY, 1921, PAET XI

EXTREMES OF DISCHARGE. 1908-1921: Maximum discharge recorded, 70 second*

feet during part of season 1919-20. 

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

well defined. Gage read to hundredths once daily. Daily discharge

ascertained by applying gage height to rating table. Records good. 

COOPERATION. Gage-height record furnished by Turlock Irrigation District,

through R. V. Meikle, chief engineer.

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

side of Tuolumne River at Indian Bar, in SW. % sec. 6, T. 2 S., R. 15 E., 15 miles 

above the town of La Grange. This canal was built in the early days to supply 

water for hydraulic mining in the vicinity of La Grange, and is now locally 

known as the La Grange mining ditch. Having been thoroughly repaired, it is 

used principally as a supply canal for the hydroelectric plant which was installed 

in 1907. The power house is on the left bank of the river about half a mile 

above La Grange and is below La Grange dam. Water diverted by canal is 

returned to river at power house except during some irrigation seasons when it 

is returned to the river above La Grange dam and sold to the Waterford Irrigation District. During 1921 the water was returned to the river above La Grange 

dam from June 1 to July 7.

MODESTO CANAL NEAR LA ORANGE, CALIF.

t

LOCATION. In SE. ^t 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, 1921.

GAGE. Vertical staff in concrete well on left bank, 500 feet below head gates. 

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 cross section of 

canal 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 OF DISCHARGE. 1903-1921: Maximum discharge, 1,340 second-feet 

part of 1920.

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

10 to February 19. Rating curves well defined. Gage read to hundredths 

twice daily. 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 good.

COOPERATION. Gage-height record furnished by Modesto Irrigation District.

The water is used for irrigation in the Modesto Irrigation District.

174 SURFACE WATER SUPPLY, 1921, PART XI

STANISLAUS RIVER NEAR KNIGHTS FERRY, CALIF.

LOCATION. In SW. ^ sec. 1, T. 1 S., R. 12 E,, 300 feet above old Tulloch dam, 

2 miles above Good win dam, and 6 miles above Knights Ferry, Stanislaus 

County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. December 18, 1915, to September 30, 1921. Also at 

Knights Ferry, May 19, 1903, to April 30, 1916.

GAGE. Water-stage recorder on right bank in reinforced concrete well and 

house.

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.

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

recorded, 9.45 feet at 8 a. m. January 18 (discharge, 16,200 second-feet); 

minimum stage from water-stage recorder, 1.10 feet at noon October 4 

(discharge, 94 second-feet).

1915-1921: Maximum discharge, 20,000 second-feet, at 3.45 a. m. February 21, 1917; minimum stage recorded, 0.94 foot from 1 to 7p.m. November 25, 1919 (discharge, 39 second-feet).

DIVERSIONS. Numerous ditches divert water for mining above the station. 

Water is also diverted from the South Fork into 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 177). The water diverted for the development of power on Middle Fork at Sand Bar Flat near Avery is returned 

to river above this station.

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

Middle, North, and South forks.

ACCURACY. Stage-discharge relation changed from that of previous year. 

Rating curve well defined. Water-stage recorder stopped several times 

during year. Mean daily gage height determined by inspecting recorder 

graph. Daily discharge ascertained by applying mean daily gage height to 

rating table, except January 17 and 18 when hourly discharge was averaged. 

Estimated periods obtained by comparison with flow of Mokelumne River 

at Clements, the gage heights at the Goodwin dam, and the maximum and 

minimum gage heights recorded by the pencil. Records good.

DIVERSION. Water is diverted from Beaver Creek into the North Fork of 

Stanislaus River about half a mile above station.

REGULATION. Flow regulated to some extent by reservoirs on the headwaters 

of this stream.

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

between 30 and 4,000 second-feet. Gage read to half-tenths once daily or 

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; low-water 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.

No discharge measurements were made during year.

1913-1921: Maximum stage recorded, 53.4 feet April 18-20, 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 good.

The following readings, at the end of each month, have been used in 

correcting the observed flow of Drew Creek below the dam:

DREW CREEK NEAR IAEEVZEW, OREG.

LOCATION. In SE. % 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 Lake view, Lake County.

DRAINAGE AREA. 211 square miles.

RECORDS AVAILABLE. January 16, 1909, to September 30, 1919, and February 23 

to September 30, 1921, when station was discontinued.

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 stagedischarge relation. One channel at all stages. Willows on right bank.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 2.32 feet 

March 14 to 22 (discharge from extension of rating curve, 550 second-feet); 

minimum discharge recorded 6 second-feet August 6-19 and August 29 to 

September 20, practically no flow reported October 1 to February 22.

1909-1919, 1921: 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.

ICE. Stage-discharge relation affected by ice during coldest weather, generally 

for one or two months.
192 SURFACE WATEB SUPPLY, 1921, PART XI

DIVERSIONS. The North Drew canal of the Goose Lake Valley Irrigation Co., 

diverts water past station; record is kept of its discharge and this is added 

to obtain the total run-off from the creek.

REGULATION. Beginning with the last part of 1912, water has been stored in the 

reservoir of the Goose Lake Valley Irrigation Co. just above station. A 

negligible quantity of water was stored prior to that time. The run-off 

records when corrected for storage are often negative during summer as the 

discharge into the reservoir becomes too small to offset the evaporation 

losses.

ACCTTEACY. Stage-discharge relation apparently permanent except when affected 

by growth of aquatic plants. Poorly defined rating curve used February 23 

to June 25; shifting-control method thereafter. Operation of water-stage 

recorder unsatisfactory; daily reading on staff gage used except for a few days 

of considerable fluctuation. Daily discharge ascertained by applying to 

rating table mean daily gage height obtained by inspecting recorder graph, 

or the daily gage reading. Records-fair.

198 SURFACE WATER SUPPLY, 1921, PART XI

SACRAMENTO RIVER WEAR BED BLUFF, CALIF.

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

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

miles above and Antelope Creek 7 miles below station.

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

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

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

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

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

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

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

because of the large noncontributing area.

RECORDS AVAILABLE. January 28, 1902, to September 30, 1921. 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. Water-stage recorder in concrete well and shelter on left bank, installed 

January 1, 1920. Outside staff gage in six sections at the well. Previous 

to January 1, 1920, record is from a staff gage in seven sections about 50 

feet below the well. Datum not changed.

DISCHARGE MEASUREMENTS. Made from cable at the gage.

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

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

recorder, 22.36 feet at noon January 30 (discharge, 127,000 second-feet); 

minimum stage from water-stage recorder, 0.45 foot at 5 a. m. October 2 

(discharge, 3,400 second-feet).

1902-1921: Maximum stage recorded, 35.2 feet February 3, 1909 (discharge, 278,000 second-feet); minimum stage from water-stage recorder, 

0.30 foot at 2.45 p. m. August 18, 1920 (discharge, 3,150 second-feet).

DIVERSIONS. The Anderson-Cottonwobd canal has diverted water from Sacramento River at Redding, since 1918. A small amount of water is diverted 

from some of the minor tributaries for irrigation.

REGULATION. No storage of any importance has been developed in the drainage 

area above station.

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

well defined. Water-stage recorder operated satisfactorily except January 

11-18 when paper tore. Daily discharge ascertained by applying mean 

daily gage height to rating tables except January 11-18 when it was estimated from flow of streams above. Records excellent.

FEATHER RIVER AT OROVILLE, CALIF.

LOCATION. In see. 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 mile*1 

above mouth of Yuba River.

DRAINAGE AREA. 3,640 square miles.

RECORDS AVAILABLE. January 1, 1902, to September 30, 1921.

GAGE. Water-stage recorder in concrete well and wooden shelter, 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.
FEATHEB EIVEE BASIN 1223

DISCHARGE MEASUREMENTS. Made from cable 1,000 feet above bridge. At

extreme low water measurements have been made from a boat 1,000 feet

below bridge.

CHANNEL AND CONTROL. Boulders and gravel; shift somewhat during high water. 

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

recorder, 14.25 feet at 4 a. m. November 19 (discharge, 82,200 second-feet);

minimum stage from water-stage recorder, 0.37 foot at 10.30 a. m. October

5 (discharge, 638 second-feet).

1902-1921: 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 from water-stage recorder, 0.39 foot at 11

a. m. September 29, 1920 (discharge, 626 second-feet). 

DIVERSIONS. Minor diversions from tributaries above 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 November 19. Rating curves

well defined below 15,000 second-feet. Operation of water-stage recorder

satisfactory except for a few short periods when observer neglected gage.

Daily discharge ascertained with a discharge integrator. Records excellent.

226 SURFACE WATER SUPPLY, 1921, PART XI

SPANISH GREEK AT KEDDIE, CALIF.

LOCATION. In SW. i sec. 22, T. 25 N., R. 9 E., at highway bridge at Keddie, 

Plumas County, 2 miles above junction with Indian Creek.

DRAINAGE ABBA. Not measured.

RECOUPS AVAILABLE. October 22, 1911, to September 30, 1921.

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 G. M. 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 downstream 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 

was partly built on control August 19, 1919, and completed during summer 

of 1921.

EXTREMES OF DISCHARGE. Maximum mean discharge recorded during the period 

February 14 to September 30 was 1,840 second-feet on March 13; minimum 

discharge probably occurred sometime during the period August 11-20. 

1911-1921: 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 sometime during the period 

October 1 to February 13 when record is considered unreliable, also July 

20 due to construction of loose rock dam on control. Rating curve fairly 

well defined. Gage read to half-tenths twice daily, but record is unreliable 

from October 1 to February 13 and discharge for this period not computed. 

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

table. Discharge for period July 21 to September 30, when dam was built 

on control, estimated from flow of Middle Fork of Feather River at Sloat 

and from the gage heights at Hadley's ranch 1 mile upstream. Records 

fair February 14 to September 30.

TUBA RIVER AT SMARTSVHIE, CALIF.

LOCATION. In sec. 22, T. 16 N., R. 6 E., at Narrows, 1 mile north of Smartsville, Yuba County, 1 mile below mouth of Deer Creek, 62^ 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.

HECORDS AVAILABLE. June 2, 1903, to September 30, 1921.

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; shift 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 .de'bris is estimated to be more than 80 feet.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 13.4 feet at 

8 a. m. January 18 (discharge, 24,800 second-feet); minimum stage, 2.48 

feet'October 2-3 (discharge, 158 second-feet).

1903-1921: Maximum stage recorded, 28.3 feet January 15, 1909 (discharge, 111,000 second-feet); minimum stage, 2.32 feet August 25, September 8 and 11, 1920 (discharge, 106 second-feet).

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

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

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

is diverted into the Bear River drainage basins.

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

19 and March 13. Rating curves fairly well defined. Gage read to quarter-tenths once daily. Daily discharge ascertained by applying gage height 

to rating table. Records fair.

bridge in Downieville, Sierra County, 500 feet above dam and one-fourth 

mile above junction with North Fork of Yuba River. East Fork of North 

Fork enters one-eighth mile above and Middle Fork of North Fork IJ^ 

miles above station.

DRAINAGE AKEA. 71.2 square miles.

RECORDS AVAILABLE. November 1, 1910, to September 30,1921.

GAGE. Vertical staff fastened to right abutment of bridge; read by J. T. Mason.

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

CHANNEL AND CONTROL. Bed consists of gravel and small boulders. Natural control at low stages is a riffle below the gage and at high stages is the dam. An 

artificial control is formed by adding flashboards of variable height to the dam.
240 SURFACE WATER SUPPLY, 1921, PART XI

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 5.50 feet 

(flashboards on dam) at 4.30 p. m. November 19 (discharge, 3,340 secondfeet); minimum stage 2.50 feet (flashboards on dam) October 1-6 (discharge, 

31 second-feet).

winters.

DIVERSIONS. The intake of the municipal water system of Downieville is above 

station.

REGULATION. None.

ACCURACY. Stage-discharge relation dependent on the presence and height of 

flashboards upon the dam and on the operation of the power plant which 

diverts water between the gage and dam. Observer reads the gage when 

plant is not running. It is usually shut down between 7.30 a. m. and 4.30 

p. m. Flashboards of variable height were used during year. Rating 

curves fairly well defined. Gage read to hundredths twice daily. Daily 

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

Records fair.

EEL RIVER BASIN

EEL RIVER AT SCOTIA, CALIF.

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

Van Duzen River 7 miles below the station.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. December 15, 1910, to February 6, 1915; October 1, 1916, 

to September 30, 1921.

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

spiked to old cofferdam on northeast corner of footing of middle pier; No. 2 

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

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

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

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

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

trestle; No. 8 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, 38.2 feet at 

7.20 a. m. November 19 (discharge, 148,000 second-feet); minimum discharge, 63 second-feet October 5.

1911-1921: Maximum stage recorded, 55.5 feet February 2, 1915 (discharge, from extension of rating curve, about 290,000 second-feet); minimum 

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

DIVERSIONS. None.

RE GULATION. None.

ACCURACY. Stage-discharge relation at low water changed January 30. Rating 

curves fairly well defined. Gage read to hundredths twice daily. Daily 

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

Records fair.

WILLIAMSON RIVER ABOVE SPRING CREEK, NEAR EL&JHATH AGENCT, OEEG.

$ ' LOCATION. In sec. 2, T. 34 S., R. 7 E., 8 miles nortre<Sl Chiloquin, 2 miles above 

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

DRAINAGE AREA. Not measured.

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

1920, to September 30, 1921. 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. Inspected by Mrs. Anna 

McKeever. 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-dispharge relation is probably affected by growth of aquatic plants. 

No definite control at temporary gage.

EXTREMES OF DISCHARGE. Minimum stage from water-stage recorder 0.12 

foot, September 15 to 18 (discharge, 16 second-feet). No record of maximum.

1917-1921: Maximum stage from water-stage recorder 3.84 feet, April 13, 

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

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

marks (discharge, estimated by extension of rating curve 2,500 second-feet. 

Minimum stage recorded, 0.19 foot July 26, 1920 (discharge, 15 secondfeet).
262 SUEFACE WATER SUPPLY, 1921, PART XI

ICE. Ice practically never forms at the station.

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

by natural flooding, and smaller areas by ditches.

RELATION. None.

ACCUKACY. Stage-discharge relation changed slightly during high-water period. 

The date of change has been taken arbitrarily as December 1. Two well 

denned rating curves used. Water-stage recorder operated in satisfacto^ 

manner October 29 to January 6, March 27 to July 14, and August 27 to 

September 30. Daily discharge obtained by applying to rating table mean 

daily gage height obtained by inspecting recorder graph. Records good except 

estimates for periods when recorder was not operating which are fair.

WILLIAMSON RIVER BELOW SPRAGTJE RIVER, NEAR CHILOQTJIN, OREG.

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

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

DRAINAGE ABBA. 2,810 square miles.

RECORDS AVAILABLE. June 25, 1917, to September 30, 1921. The sum of discharge records at stations on Williamson and Sprague rivers above their 

junction is directly comparable with these records.

GAGE. Friez water-stage recorder on left bank 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 from water-stage 

recorder, 3.42 feet at noon March 13 (discharge, 3,260 second-feet); minimum stage from water-stage recorder, 0.35 foot at 6 a. m. October 14, very 

uncertain as drum of recorder slipped (discharge estimated as sum of Williamson River above Spring Creek, 320 second-feet).

1911-1921: Maximum discharge obtained by adding results obtained at 

stations above junction, about 7,000 second-feet April 27, 1917; Williamson 

River estimated from high-water mark as 2,500 second-feet. Minimum 

stage recorded that of 1921.

ICE. Stage-discharge relation affected by ice, during extremely cold winters.

DIVERSIONS. Modoc Point canal diverts past the station. Large areas of 

land are irrigated from the river and its tributaries.

ACCURACY. Stage-discharge relation practically permanent. Affected by ice 

in January and February and by logs on control September 17-30. Welldefined rating curves used October 1 to September 16 and September 17-30, 

Gage-height record good except for January and February and short periods 

at other times. Daily discharge ascertained by applying to rating table 

mean daily gage height obtained by inspecting recorder graphs. Records 

good except for periods when recorder was stopped or stage-discharge relation affected by ice, for which they are fair.

KLAMATH EIVEB, BASIN 265

UPPER KLAMATH LAKE NEAR KLAMATH FALLS. ORE6.

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, 1921.

GAGE. Friez water-stage recorder February 16, 1906, to June 16, 1918; vertical 

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

date. Zero on gage is 4,136.13 feet above sea level. Gage readings 1918 

to 1921, reduced to a datum of 4,100 feet. During 1904 and 1905, vertical 

staff on Pelican Bay; zero 4,137.78 feet above sea level (United States 

Bureau of Reclamation datum) as determined by E. C. LaRue on June> 

1920.

EXTKEMES OP STAGE. Maximum stage recorded during year, 42.85 feet April 

4; minimum stage recorded, 39.33 feet October 5.

1904-1921: Maximum stage, 4.144.98 feet (United States Bureau of 

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

marks May 28, 1904; minimum stage recorded that of 1921.

FLUCTUATION. Gage heights very much affected by wind. Water is lowered 

near outlet when wind blows from south and is raised as much above its 

normal level when wind is in opposite direction. There is a periodic oscillation when wind blows for any length of time.

REGULATION. Water stored by a temporary dam at outlet of lake, beginning 

April 15, 1919.

COOPEKATION. Record for 1921 furnished by California-Oregon Power Co. and 

United States Bureau of Reclamation.

" Average of two readings a day. Gage not read May 11, 12, and June 7.
266 SURFACE WATER SUPPLY, 1921, PART XI

LINE RIVER AT KLAMATH FALLS, OREG.

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

bridge over Link River, 1J4 miles below outlet of Upper Klamath Lake, and 

immediately above head of Lake Ewauna at Klamath Falls, Klamath County.

DRAINAGE AREA. 3,110 square miles.

RECORDS AVAILABLE. May 15, 1904, to September 30, 1921.

GAGE. Friez water-stage recorder on left bank; elevation of zero is 4,080.0 feet 

above sea level. Friez recorder on opposite bank and a little farther upstream was used June 6, 1908, to August 30, 1912: Chain gage on bridge 

used 1904 to 1908. Gage reader, Marie Talbot.

DISCHARGE MEASUREMENTS. Made from bridge; section deep, current sluggish 

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 Calif ornia-Oregon Power Co.'s plant, which 

enters the river opposite gage appears to affect stage the same as if it came 

down river channel.

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

recorder,*8.30 feet at 3 p. m. April 4 (discharge, 5,000 second-feet); minimum 

stage during year from recorder, 4.67 feet August 13 (discharge, 366 secondfeet).

1904-1921: Maximum stage, 7.30 feet at gage at bridge May 12, 1904, 

determined May 15, 1904, from high-water marks (discharge, 9,400 secondfeet); minimum stage, 4.07 feet, August 30, 1918, determined by leveling 

(discharge estimated at 22 second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. The main or A canal of the Klamath project of the United States 

Bureau of Reclamation diverts water from Link River immediately below 

Upper Klamath Lake. Record is kept of this diversion. (See pp. 284-285.) 

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 changing during year. Rating curves and 

periods of application poorly defined. Operation of recorder not satisfactory 

because observer did not read staff gage but recorded position of pencil on 

graph; recorder graphs corrected by daily staff gage reading made by an 

employee of the California-Oregon Power Co. Discharge determined^ by 

applying corrected mean gage heights from graph, or daily staff gage reading, 

when recorder was not operating, to rating tables, and method of shifting 

channel January 13 to April 27. Records fair.

COOPERATION. Most of field data furnished by United States Bureau of Reclamation, H. D. Newell, project manager.

KIAMATH RIVER AT SPENCER BRIDGE, NEAR 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, 1921. 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. Gage reader Mrs. Roy F. Beck. Datum lowered 1.0 foot June 21, 

1918, and 0.56 foot July 16, 1921.

DISCHARGE MEASUREMENTS. Made from upstream side of wagon bridge, or by 

wading at low water just above bridge.

CHANNEL AND CONTROL. Heavy gravel and boulders; practically permanent; 

bed even.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 3.32 feet 

March 24 (discharge, 4,270 second-feet); minimum stage recorded, 1.28 

foot August 11, new datum (discharge, 640 second-feet). The true maximum 

was probably about 4,700 second-feet, estimated April 4 and 5 from records 

at Copco.

1913-1921: Maximum stage recorded 2.42 feet, original datum April 21, 

1914 (discharge, 5,130 second-feet); minimum stage recorded, 0.38 foot 

August 3, 1918 (discharge, 386 second-feet). A stage of 15. 3 feet (discharge, 

9,250 second-feet), occurred at Keno station about May 10, 1904.
KLAMATH RIVEfe BASIN 269

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 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 due to 

effect of wind on the wide flat stretches of river above Keno.

ACCURACY. Stage-discharge relation probably permanent throughout year 

except as affected by change of gage datum July 16. Two fairly well defined 

rating curves used. Staff gage read to hundredths three times a week 

October 1 to March 26 and July 16 to September 30, occasional readings at 

other times. Daily discharge ascertained by applying daily gage heights to 

rating tables; mean discharge estimated for periods when gage was not read. 

Records good except for periods when discharge was estimated for which 

they are fair.

 COOPERATION. Field data furnished by United States Bureau of Reclamation, 

H. D. Newell, project manager, Klamath project.

LOCATION. In NW. M 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, 1921, fragmentary.

GAGE. Vertical staff gage with duplicate inclined section on left bank; read by 

L. F. Belknap. Stevens water-stage recorder at same location used 

February 20, 1914, to September 11, 1917.

CHANNEL AND CONTROL. Bed composed of sand and gravel; no definite control 

as stream is very sluggish for miles above and below gage; banks subject to 

overflow at a stage of about 5 feet and considerable water may flow in a 

cut-off across a bend to the right of the station.

DISCHARGE MEASTTBEMENTS. 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 recorded during period 5.6 feet 

March 6 (discharge, 1,270 second-feet); minimum stage 0.92 foot September 

13-19 (discharge, 102 second-feet).

1912-1920: Maximum stage from water-stage recorder, 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 unstable owing to growth of aquatic 

plants. Fairly well defined rating curve used October 1 to June 15, indirect 

shifting control method thereafter. Gage read to hundredths about three 

times a week. Daily discharge ascertained by applying daily gage reading 

to rating table. Records good.

August 2, 1920 (discharge, 3.2 second-feet, uncertain).

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. ,

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

nine discharge measurements in 1920 and 1921 and two in 1922. Operation of water-stage recorder satisfactory except for short periods. Daily 

discharge ascertained by applying to rating table mean daily gage height 

obtained by inspecting recorder graph. Records excellent except during 

part of winter when recorder was not operated, and for periods when recorder was not operating satisfactorily, for which they are fair.
