^En the execution of the work many private and State organizations 

have cooperated, either by; furnishing data or by.assistlqig^ui^Ue.ctiqg 

da^a- 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, itO. , ». 

, Measurements of stream flow have been made at aboul 5,120 points 

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

Hawaiian Islands. In July, 1925,-1,710 gaging "stations were being 

maintained by the Geological Survey and the cooperating organizations. 'Ivf airy miscellaneous diBcha^nieasurements are nt-id^at dtiier

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. '"' " ' '' ' OF , (

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 % certain class oi work. These, terms *«may* be divided 

into two groups (1) those that represent a, rate of flow, as secondfeet, gallons' per minute, miner's inches, and discharge 1151 second-feet 

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

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

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

defined as follows:

 *

"Second-tfeet" 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 tised' as a fundamental 

ttmtirom which others are computed.

" Second-feet per square mite' * 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.

" Eun-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 use4 for, comparing run-off with 

rainfall, -which is usually expressed in, inches. . . . As "acre-foot," equivalent to 43,660 cubic feet, is the quantity 

required to cover an acre to the depth of 1 foot. The term i& com* 

monly 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 dischargp."

"Control"; a term used to designate the section or sections of the 

stream below the gage which determines the stage-discharge relation 

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

same section or sections at all stages.

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

^age the gage height at which water ceases to flow over the control.

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

measurements of flow made on streams in the United Statef during 

the year ending September 30,1925. "*

The data.presented in these reports were collected by the United 

States Geological Survey under the following authority contained in 

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

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

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

The work was begun in 1888 in connection with special studies 

relating to irrigation. Since the fiscal year ending June 30, 1895, 

appropriation bills passed by Congress have carried the following 

items:

For gaging the streams #nd determining the water supply of the United States; 

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

preparation of reports upon the best methods of utilizing the water resou,rces.

In the execution of the work many private and State organizations 

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

da$a. Acknowledgments for cooperation of the first kind a.re 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 5,120 points 

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

Hawaiian Islands. In July, 1925, 1,710 gaging'stations were being 

maintained by the Geological Survey and the cooperating organizations. Many miscellaneous discharge measurements are ma.de.at other 

points. In connection with this work data wfere 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^sdth a certain class of work. These terms maybe divided 

into two groups (1) those that represent a rate of flow, as secondfeet, gallons" per minute, miner's inches, and discharge in second-feet 

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

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

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

defined as follows:

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

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

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

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

unit irom 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 below the gage which determines the stage-discharge relation 

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

same section or sections at all stages.

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

gage the gage height at which water ceases to flow over the control.

EXPLANATION OF DATA

The data presented in this report cover the year beginning October 1, 1924, and ending September 30, 1925. At the beginning of 

January in most parts of the United States much of the precipitation
EXPLANATION OF DATA

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 runoff is possibly a small quantity in the ground; therefore the run-off for 

the year beginning October 1 is practically all derived from precipi* 

tation within that year. . - 

The base data collected at gaging stations consists 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 disFIGURE 1. Typical gaging station ,

charge are made with a current meter. The general methods are 

outlined in standard textbooks on the measurement of river discharge. A typical gaging station, equipped with water-stag'e recorder 

and measuring cable and car, is shown in Figure 1.

From the discharge measurements rating tables are prepared that 

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

height to these rating tables gives the daily discharge from which 

the monthly and yearly mean discharge is determined. ..i

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

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

of discharge measurements, a table showing the daily discharge of the 

stream, and a table of monthly and yearly discharge and run-off.

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

tables giving daily gage heights and results of discharge measurements 

are published. ,.;
4 SURFACE WATER SUPPLY, 1925, PART XI

 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.

Jn 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 now in cubic feet for each::second during the month. 

Onjt this average flow, computations Jtecorded in the remaining columns* wJiich. 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, measurements of flow, and interpretation of 

records. ; ., .- -- 

 A paragraph in the description of the station gives information 

regarding (1) the 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 heights to the rating table to obtain 

the daily discharge.

 ' : For the rating tabl.es "well defined" indicates, in general, that the 

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

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

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

individual measurements with reference to the mean rating curve.
\ .'.. PUBLICATIONS

The monthly means foi* any station may 

racy the quantity of water flowing past the gage, hut the figures 

showing discharge per square mile and.depth of run-pff in inches 

may be subject to gross errors caused by the,,inclusion of large noncontributing districts hi 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 th'e flow 

of the river above the station. "Second-feet per square mile" and 

"run-off,in niches" are therefore not' computed if such errors;appear 

probable. The computations are also omitted for stations on. str(e$ms 

draining areas in which the annual rainfall is less than 20 incji^g* 

All. figures representing "second-feet per square mile" an$ "run-o^ 

in inches" published in earlier reports by the Geological Sujrvje^ 

should be used with caution because of possible inherent, but unknown, 

sources of error. - p-.

Many gaging stations on streams in the irrigated areas of; 

United States are located above most of the t^yersions from th^se 

streams, and the discharge recorded does not show the water su|mte 

available for further development, as prior appropriations below tne 

stations must first be satisfied. To ^giye an idea.of the ajnounj, e^ 

prior appropriations, a paragraph on diversions is presented in each 

station description. Where figures are given they can not be considered exact but as being 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 preJiminary 

estimates; the tables of daily discharge allow more detailed studies 

of the variation hi flow. It should be borne in mind,'hoW'ever1, that 

the observations in each succeeding year may be expected! to,throw 

new light on d&t& previously published.

Investigation of water resources by the United States Geological 

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

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

it has comprised also investigation of such closely allied subjects as 

irrigation, water storage, water powers, ground waters, and quality of 

waters. Most of the results of these investigations have been published in the series of water-supply papers, but some have, appeared hi 

the monographs, bulletins, professional papers, and annual reports.

The results of stream-flow measurements are now published annually in 12 parts, each part covering an area whose boundaries coincide 

with natural drainage features as indicated below: '''«

COOPEBATION

Investigation of the water resources of California is being carried 

on by the United States Geological Survey in cooperation with the 

State m 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 ta enter into contracts with the Director of the United States Geological Survey for the purposed 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 1925 was maintained in accordance with the contract signed by W. F. McClufej 

State engineer. Additional funds were provided by the division of 

engineering and irrigation to maintain certain stations in the lower 

Sacramento and San Joaquin River Basins during the irrigating season. 

Additional funds for the maintenance of river-measurement stations 

were provided by a special act of the State legislature, chapter 309, 

statutes of 1923, and disbursed by the division of- water rights, 

Department of Public Works of the State of California, through 

Edward Hyatt, jr., chief of the division.

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

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

engineer.

All stations in Los Angeles County are maintained in cooperation 

with the board of supervisors and the Department of Agriculture, 

represented by the Forest Service through F. E. Bonner, district engineer, and the Weather Bureau through H. B. Hersey, .meteorologist. 

Los Angeles County and the Forest Service each pay the salary and 

expenses of one hydrographer detailed for field work. The Geological 

Survey supervises the work and compiles all stream-flow .data for 

publication,

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

their boards of supervisors. Cooperation is also furnished by the 

Weather Bureau-in maintaining precipitation stations.

Assistance in the maintenance of river-measurement stations was 

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

SAN DIEGO ftXVXB BASIN

SAN DIEGO RIVER NEAR SAHTBE, CALIF.

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

DRAINAGE AREA. 375 square miles (measured on topographic maps) for station at old Mission Dam.

RECORDS AVAILABLE. May 25, 1912, to September 30, 1925 (record not complete).

GAGE. Water-stage recorder on right bank at loop dam site, 1% miles below 

old Mission Dam. Prior to November 20, 1920, station was at old Mission Dam.

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 incomplete control.

EXTREMES of DISCHARGE. 1912-1925: 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 that is 

forced to surface.

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

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

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

COOPERATION. Gage-height record and results of several discharge measurements furnished by Cuyamaca Water Co., Ed Fletcher, manager.

There was no flow at this station during the year except for a small amount 

of ground water forced to the surface by solid bedrock control. This amounted 

to less than 1.0 second-foot at any tune and except for a few days was not more 

than 0.2 second-foot.

BOULDER CREEK 1TEAR JUUAK, CALIF.

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

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

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

RECORDS AVAILABLE. June 19,1912, to September 30, 1925.

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

elevation of crest of the 6-foot Cippoletti weir, which is 100 feet below 

outlet gates of reservoir. Gage read by watchman at dam.

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

velocity of approach, it has been necessary to rate weir.

CONTROL. Cippoletti weir acts as control.

EXTREMES OF DISCHARGE. Maximum mean daily discharge during year, 16.1 

second-feet August 7,17,26-27; stream dry several months during year.

1912-1925: 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 and enlarged in 1894, has a 

capacity of 11,400 acre-feet. From the reservoir the water flows 12J^ 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 practically permanent. Rating curve well 

defined. Gage read to hundredths daily; additional observations are made 

when reservoir gates are changed. Records excellent.

COOPERATION. Gage-height record and results of one discharge measurement 

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

SANTA ANA RIVER NEAR PR A DO, C&IIF.

LOCATION. At Riverside-Orange County line in lower Santa Ana Canyon, 3 

miles by river below Rincon Bridge and 3 miles southwest of Prado, Riverside County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. January 31, 1919, to September 30, 1925.

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

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

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

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

Banks covered with trees and brush.

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

recorder, 1.93 feet at 11 p. m. April 5 (discharge, 467 second-feet); minimum 

discharge, 45 second-feet at 8 p. m. July 26.

1919-1925: Maximum stage, from water-stage recorder, 5.45 feet at 3 a. m. 

February 23, 1920 (discharge, about 7,560 second-feet); minimum discharge, 

41 second-feet at 8 p. m. July 15, 1919.
28 SURFACE WATER SUPPLY, 1925, PART XI

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

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

out of underground storage by flowing wells and pumping plants.

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

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

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

Creek only during seasons of very high run-off. (See Elsinore Lake at Elsinore, p. 60.)

ACCURACY. Stage-discharge relation continually changing. Standard rating 

curves not well defined. Water-stage recorder gave excellent record. Daily 

discharge ascertained by shifting-control method. Records fair.

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

CALIF.

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

of canyon, 2% miles below intake on Santa Ana Eiver and 3 miles northeast of Mentone, San Bernardino County.

RECORDS AVAILABLE. 1896 to September 30,1925.

DISCHARGE. Canal discharge computed from records showing kilowatt output 

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

EXTREMES OF DISCHARGE. 1896-1925: Maximum mean daily discharge of canal, 

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

year.

DIVERSIONS. Water diverted from the fore bay of power plant by the Greenspot pipe line must be added to give total flow of canal above fore bay. 

From 1903 to 1911 pipe line diverted from canal above fore bay, but no discharge was reported. The present pipe line was put in operation September 

7, 1911.

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

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

considered good.
32 SURFACE WATER SUPPLY, 1925, PAET XI

COOPERATION. Record furnished by Southern California Edison Co. through 

H. W. Dennis, chief civil engineer.

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

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

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

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

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

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

Mentone, Calif., for the year ending September SO, 1926.

MILL CHEEK NEAR CBAFTONVI1LE, CALIF.

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

Bernardino County. 

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. January 21,1919, to September 30, 1925. 

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

Co.'s concrete diversion dam. Datum lowered 1 .foot November 21, 1922. 

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

by wading.
SURFACE WATER SUPPLY, 1925, PART XI

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

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

on account of the gravel which collects at the dam.

EXTREMES OP DISCHARGE. Maximum discharge during year, estimated by 

observer, about 3 second-feet on December 16, 17, 22, and 23. All water 

diverted into Mill Creek power canal No. 1 except for a few hours on each 

of the days listed above.

1919-1925: Maximum stage recorded, 4.80 feet December 20, 1921 (discharge, about 896 second-feet); all water diverted into Mill Creek power 

canal No. 1 at various times.

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

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

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

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

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

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

power plant No. 1. Water is diverted from Mill Creek by canal No. 1 

only when the water discharged from the combined power house is insufficient to operate power plant No. 1 to capacity.

ELSINORE LAKE AT ELSINOBE, CALIF.

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

RECORDS AVAILABLE. December 1, 1915, to September 30, 1925.

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

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

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

SURFACE WATER SUPPLY, 1925, PAS® XI

SAN GABRIEL RIVER BASIN 

SAN GABRIEL BITER NEAR AZUSA, CALIF.

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

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

and 2 miles north of Azusa, Los Angeles County,

DRAINAGE AREA. 214 square miles (revised measurement).

RECORDS AVAILABLE. 1894 to September 30, 1925.

GAGE. Water-stage recorder on right bank at the cable, 1,000 feet above ford 

at mouth of canyon, and 500 feet above the tunnel diversion; installed 

November 18,1922. On account of frequent changes in channel it has been 

necessary to install numerous staff gages and three recorder wells near the 

ford. These have been at independent datum planes.

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

wading.

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

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

recorder, 5,10 feet at noon April 4 (discharge, 3,000 second-feet); no flow 

October 1 to December 16, December 20 to March 5, March 11-28, and 

May 3 to September 30.

1894-19251 : 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. (For daily discharge of this canal see p. 69.)

REGULATION . None.

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

curve well defined below 1,000 second-feet; extended above. Water stage 

recorder record poor owing to debris from burned-over area clogging the 

inlet to the well. Graph partly estimated from numerous staff gage readings, 

measurements, and estimates of flow. Daily discharge ascertained by 

applying mean daily gage height to rating table, for days for which gageheight graph was available, by estimating and by interpolating between 

measurements. Records fair.

LOCATION. In NW. M NW. ^ see. 23, T. 1 N., R. 10 W., half a mile above

mouth of creek and 2J^ miles north of Azusa, Los Angeles County. 

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

RECORDS AVAILABLE. October 1, 1917, to September 30, 1925. (Discharge

measurements only, May 8, 1916, to June 11, 1917.) 

GAGE. Water-stage recorder on left bank at mouth of canyon. 

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

gage. 

CHANNEL AND CONTHOL. During fall of 1924 the drainage area was burned over,

causing sand and debris to be washed down the stream, completely covering

the pool and control. 

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

recorder, 6.50 feet at 10 a. m. April 4 (discharge, 1,470 second-feet); stream

dry during summer.

1917-1925: Maximum discharge recorded, 1,470 second-feet at 10 a. m.

April 4, 1925; stream dry several months each year.
SAN GABBIEL BIVBR BASIST

DIVERSIONS. Two small diversions above the station diverted all the water at 

times during the year.

REGULATION. None.

ACCURACY. Stage-discharge relation continually changing as channel of stream 

has been filled with sand and d4bris owing to \ urning over of the drainage 

area in 1924.' Several rating curves used. Water-stage recorder record 

only fair as the intake clogged with debris frequently. Daily discharge 

ascertained by shifting-control method and by interpolating between discharge measurements. Hourly discharge averaged February 20, March 6, 

29, 31, April 4, 5, 20, 22, and May 20. Records fair.

SAN DIMAS CREEK HEAR SAN DIM AS, CALIF.

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

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

DRAINAGE AKEA, 18.3 square miles (measured on topographic map).

RECORDS AVAILABLE. December 3, 1916, to September 30, 1925. (Discharge 

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

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

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

wading.

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

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

1921 a wooden dam about 2J^ feet high was built on the control. There 

is a notch in it, in which are placed one or more planks to raise water so it 

can be diverted through a 12-inch pipe. This dam is removed at times. 

Gravel fills in above dam, affecting stage-discharge relation. Left bank is 

steep and not subject to overflow; right bank is brushy and is overflowed 

during high stages.

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

recorder, 4.83 feet at 10 a.m. January 26 (discharge, 6.2 second-feet); practically no flow October 1 to November 9 and July 25 to September 30.

1916-1925: Maximum stage, from water-stage recorder, 5.95 feet at 2 p. m. 

February 9,1922 (discharge, about 1,140 second-feet); stream often dry for 

several months during the year.

DIVERSIONS. The San Dimas Water Co. diverts practically the entire flow 

below the gage.

REGULATION. Complete regulation at the Los Angeles County Flood Control 

District dam about half a mile upstream.

ACCURACY. Stage-discharge relation changed frequently owing to leakage 

between flashboards and concrete control. Rating curve fairly well defined. 

Water-stage recorder record good. Daily discharge ascertained by applying 

mean daily gage height to rating table, using the shifting-control method, 

except for the period July 11-24, for which it was estimated. Records good.

TUJUNGA CREEK WEAK SUNIAND, CAIIF.

LOCATION. Near center of sec. 32, T. 3 N., R. 13 W. (unsurveyed), at a partly 

constructed and abandoned dam, 2 miles above mouth of canyon and 4 miles 

northeast of Sunland, Los Angeles County.

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

RECORDS AVAILABLE. October 28, 1916, to September 30, 1925. Discharge 

measurements only, April 1 to August 27, 1916.

GAGE. Water-stage recorder on right bank above dam.

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

by wading.

CHANNEL AND CONTROL. Bed consists of gravel and boulders. Control is concrete dam, which has a notch in center about 20 feet long and 1 foot deep.- 

Stage-discharge relation affected by deposits of sand and gravel above the 

dam.

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

recorder, 2.23 feet at 3 a. m. April 5 (discharge, 325 second-feet); minimum 

discharge, 0.1 second-foot, October 1-5.

1916-1925: Maximum stage recorded, 6.20 feet at 5 p. m. December 19, 

1921 (discharge, 8,600 second-feet); minimum discharge estimated at 0.1 

second-foot, September 20-23,1919, and several days in August, September

> and October, 1924.

DIVERSIONS. Two or three ranches divert part of the low-water flow for irrigation above the station. There are two small diversions between gage and 

mouth of canyon.

REGULATION. None.

ACCURACY. Stage-discharge relation not permanent. Water-stage recorder record good, except during very low stages when water does not reach well. 

Daily discharge ascertained by shifting-control method or by interpolation 

between measurements during low water. Records fair.

HAINES CREEK NEAR TUJDNGA, CALIF.

LOCATION. In NE. }4 NE. }4 sec. 18, T. 2 N., R. 13 W., 800 feet above mouth 

of canyon and IJ^j miles northeast of Tujunga, Los Angeles County.

DRAINAGE AREA. 1.2 square miles.

RECORDS AVAILABLE. February 7,1917, to September 30, 1925.

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

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

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

water, is located just above gage.

CHANNEL AND 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 th®
84 SURFACE WATER SUPPLY, 1025, PART XI

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

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

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

for low stages. Zero flow, gage height, 0.23 foot.

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

recorder, 0.80 foot at 9.30 a. m. April 4 {discharge, 1.1 second-feet); practically dry August 29 to September 30.

1917-1925: Maximum stage recorded, 1.74 feet January 2,1922 (discharge, 

15 second-feet); stream dry July 18 to August 1, 1921, and August 29 to 

September 30, 1925.

DIVEESIONS. 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. 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.

ACCUEACY. Stage-discharge relation permanent. Rating curve fairly well defined. Operation of water-stage recorder satisfactory except March 21-24 

and June 21 to July 26, August 7-10, and August 29 to September 30. 

Daily discharge ascertained by applying mean daily gage height to rating 

table, except for periods noted above for which it was estimated. Records 

good.

ICE. Stage-discharge relation seriously affected by ice from December 16 to 

March 17.

ACCURACY. Stage-discharge relation changed at low water, probably due to 

undermining of artificial control. Rating curves fairly well defined. Waterstage recorder record excellent, except December 16 to March 17, when well 

was frozen. Daily discharge ascertained by applying mean daily gage height 

to rating table, except October 28, 29, and November 9, for which hourly 

discharge was averaged. Records good.

SODTE FORK OF SAN JOAQUIN BIVER NEAR FLORENCE LAKE, CALIF.

LOCATION. In sec. 36, T. 7 S., R. 27 E., Fresno County, 2 miles northwest of 

Florence Lake and 6 miles above mouth of Bear Creek. Elevation about 

7,200 feet.

DRAINAGE ABBA. Not measured.
140 SURFACE WATER SUPPLY, 1925, PART XI

RECOKDS AVAILABLE. December 29, 1921, to September 30, 1925.

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

DISCHARGE MEASUREMENTS. Made from cable one-third mile below gage or by 

wading.

CHANNEL AND CONTROL. Solid granite and boulders at gage. Control is a low 

concrete dam, subject to slight erosion. One channel at all stages; banks 

not subject to overflow.

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

recorder, 12.80 feet at 11 p. m. May 28 (discharge, 2,120 second-feet); minimum stage, 7.77 feet August 30 and September 2-7, stream practically dry, 

owing to diversion above.

1921-1925: Maximum stage, from water-stage recorder, 13.75 feet at 10 

p. m. June 4, 1922 (discharge, 3,460 second-feet); minimum stage August 

30 and September 2-7, 1925, stream practically dry.

ICE. Stage-discharge relation seriously affected by ice December 18-26, January 

15-16, and February 23.

DIVERSIONS. Beginning April 13, 1925, most of the flow of South Fork of San 

Joaquin River was diverted half a mile above the gage by Florence Lake 

Tunnel (see p. 149) to Huntington Lake on Big Creek.

REGULATION. Flow regulated by storage in Florence Lake and control at 

diversion dam.

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

very well defined. Water-stage recorder record excellent except when 

affected by ice. Daily discharge ascertained by applying mean daily gage 

height to rating table, except during ice-affected period, for which it was 

ascertained by comparison with records for near-by stations, and April 13-21, 

28 and 29, May 14, 17-23, June 7, 9-27, July 1 and 2, for which it was ascertained by use of discharge integrator or by averaging hourly discharge. 

Records excellent.

COOPERATION. Gage-height record and results of discharge measurements furnished by Southern California Edison Co., through H. W. Dennis, chief civil 

engineer.

PITMAN CREEK AT BIG CREEK, CALIF.

LOCATION. In sec. 28, T. 8 S., R. 25 E., one-fourth mile above junction with

Big Creek and half a mile southeast of Big Creek post office, Fresno County.

Elevation, 5,000 feet. 

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

Light & Power Co.). 

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

1922, to September 30, 1925.
SAN JOAQUIN RIVER AND TRIBUTARIES ABOVE FRESNO RIVER 171

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

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

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

by wading.

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

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

velocity of approach at high stages.

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

recorder, 2.00 feet at 7 p. m. May 4 (discharge, 488 second-feet); minimum 

stage, from water-stage recorder, 0.03 foot October 1-5 (discharge, 0.6 

second-foot).

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

based on computations from'formula, without discharge measurements, and 

considered not so reliable as later records.

1921-1925: Maximum stage, from water-stage recorder, 3.53 feet at 6 

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

water-stage recorder, 0.03 foot October 1-5, 1924 (discharge, 0.6 secondfoot).

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

crest occasionally and caused backwater, for which allowance was made 

before application of open-water rating.

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

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

maximum diversion, 0.5 second-foot.

REGULATION. None.

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

Gage heights slightly affected by ice during winter and proper corrections 

made. Water-stage recorder record excellent. Daily discharge ascertained 

by applying mean daily gage height to rating table, except October 28, 29, 

November 9, and April 14, for which hourly discharge was averaged. 

Records excellent.

SAN JOAQUIN RIVER AND TRIBUTARIES ABOVE FRESNO RIVER 173

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

recorder, 0.83 foot at noon February 6 (discharge, 19 second-feet); practically dry during first part of October.

1916-1920; 1922-1925: Maximum mean daily discharge, from waterstage recorder, 712 second-feet on April 7, 1920; practically no flow July to 

about October 15, 1924.

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

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

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

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

mouth. See page 174 for daily discharge of the flume.

REGULATION. Flow is regulated at Shaver Lake Dam. There were 1,845 acrefeet of water in Shaver Lake on September 30, 1924, and 3,070 acre-feet on 

September 30, 1925.

ACCURACY. Stage-discharge relation shifting during October and November. 

Rating curve December 1 to September 30 well defined. Water-stage 

recorder record excellent. Daily discharge ascertained by applying mean 

daily gage height to rating table except November 9, February 6, July 24, 

August 10 and 13, September 11 and 12, for which hourly discharge was 

averaged and November 1-5 and 28-30, for which it was estimated. Mean 

monthly discharge estimated for October. Records good except for October 

and November, for which they are fair.

COOPERATION. Gage-height record and results of discharge measurements furnished by Southern California Edison Co., through H. W. Dennis, chief 

civil engineer.

MERCED RIVER AT EXCHEQUER, CALIF.

LOCATION. About on section line between sees. 14 and 23, T. 4 S., R. 15 E., 1 

mile below remains of old dam at Exchequer, Mariposa County, 8 miles 

above Merced Falls. Prior to October 25, 1922, station was maintained at 

old dam at Exchequer.

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

maps).

RECORDS AVAILABLE. November 28, 1915, to September 30, 1925.

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

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

CHANNEL AND CONTROL. Channel is solid rock, overlain with gravel. Channel 

and control permanent. Banks high, clean, are not overflowed.

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

recorder, 12.35 feet at 1 p. m. February 6 (discharge, 15,400 second-feet); 

minimum stage, about 0.00 foot from 5 a. m. to noon August 10, water being 

stored (discharge, 20 second-feet).

1915-1925: Maximum discharge, about 22,000 second-feet at 4 p. m. 

January 17, 1916; minimum discharge, 14 second-feet part of August or 

September, 1919 to 1921.

DIVERSIONS. None.

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

effect of their operation is slight except during low water when they alternate 

with the plant at Merced Falls in storing water and developing power twice 

daily. Slightly regulated by gates in new Exchequer Dam now under 

construction.

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

well defined. Recorder record excellent, except December 13-15, 20-28, 

and March 10-19 when recorder did not operate. Daily discharge ascertained by applying mean daily gage height to rating table, except October 

29, November 9, 10, December 8, February 6, and 12, for which hourly 

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

record. Records good.

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

184 SURFACE WATER SUPPLY, 1925, PART XI

MERCED RIVER NEAR MERCED FALLS, CALIF.

LOCATION. In sec. 11, T. 5 S., R. 15 E., 1,500 feet above Yosemite Valley Railroad trestle 26-B and 2^ miles above Merced Falls, Mariposa County.

DRAINAGE AREA. 1,090 square miles at former site.

RECORDS AVAILABLE. April 6, 1901, to November 30, 1913, and April 1, 1923, 

to September 30, 1925.

GAGE. Water-stage recorder in a 24-inch steel pipe well and shelter on right 

bank. Gage used in 1913 was about half a mile downstream.

DISCHARGE MEASUREMENTS. Made from cable at gage.

CHANNEL AND CONTROL. Channel is gravel and sand. Control is a rock and 

gravel riffle 500 feet below gage. One channel at low and two at high stagesChannel straight above and below gage. Water is swift and smooth. Right 

bank high and wooded, left bank low and will be overflowed.

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

recorder, 9.17 feet at 2 p. m. February 6 (discharge, 15,500 second-feet); 

minimum stage, 0.80 foot August 10 (discharge, 4 second-feet).

1901-1913; 1923-1925: Maximum discharge, 37,200 second-feet January 

30, 1911; no flow November 21, 1901.

DIVERSIONS. None.

REGULATION. No large storage above station. Power plants above station 

and at Merced Falls alternated in storing water and developing power 

twice daily during low-water period. This causes a diurnal fluctuation of 

about half a foot. A small amount of storage at Exchequer Dam affects 

flow. Exchequer Dam is not completed.

ACCURACY. Stage-discharge relation changed February 6. Rating curves well' 

denned between 100 and 3,000 second-feet. Water-stage recorder record' 

excellent, except September 6-16, when clock stopped. Daily discharge 

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

the period September 6-16, for which it was interpolated. Records good.

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

The following discharge measurements were made:

March 29, 1925: Gage height, 2.82 feet; discharge, 1,980 second-feet.

September 24, 1925: Gage height, 0.28 foot; discharge, 64 second-feet.

Daily discharge, in second-feet, of Merced River near Merced Falls, Calif., for the 

year ending September SO, 1925

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

Dam. Prior to the construction of Don Pedro Dam, the canal diverted at 

Indian Bar, 7;Hj miles upstream. Water was used for power up to May 23, 

1923, and returned to river hah* a mile above bridge at La Grange. After 

May 22, 1923, water was used to supply the town of La Grange. See page 

206 for record of this canal. There is also a diversion from South Fork of 

Tuolumne River at Harden ranch for irrigation near Groveland.

REGULATION. Completely regulated by gates in Don Pedro Dam. There was 

71,300 acre-feet of water in Don Pedro Reservoir September 30, 1924, and 

201,540 acre-feet September 30,1925. Water is also stored in Hetch Hetchy 

Reservoir and Lake Eleanor. See pages 188 and 198.

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

well defined. Water-stage recorder record excellent, except December 4-11, 

when record paper tore and stopped the clock. Daily discharge ascertained 

by applying mean daily gage height to rating table. Discharge December 

4-11 estimated from power-house records. Records excellent.

The following discharge measurements were made:

May 24,1925: Gage height, 14.30 feet; discharge, 9,890 second-feet.

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

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

Dam, just above waste gate, 1J4 miles northeast of La Grange, Stanislaus 

County, and 4 miles below intake at Don Pedro Dam on Tuolumne River.

RECORDS AVAILABLE. 1908 to September 30, 1925 (not complete).

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

J. L. Beltz.

DISCHAEGE MEASUREMENTS. Made in flume just below gage.

CHANNEL AND CONTROL. Rectangular ditch excavated mostly in shale rock.
TUOLUMNE RIVER BASIN 207

EXTREMES OF DISCHARGE. 1908-1925: Maximum discharge recorded, 72 secondfeet November 28, 1921.

ACCURACY. Stage-discharge relation permanent 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 Don Pedro Dam. It originally diverted water at Indian 

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

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

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

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

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

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

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

was discontinued, and the record now shows the amount of water diverted to 

supply the town of La Grange. Considerable more water is diverted at Don 

Pedro Dam than passes the gaging station on the canal. Most of this water is 

wasted back into the river above La Grange Dam, as the canal is in bad repair 

and is not to be used after a pumping, plant is installed .to supply La Grange 

with water.

The following discharge measurement was made:

May 23, 1925: Gage height, 0.18 foot; discharge, 0.5 second-foot.

Daily discharge, in second-feet, of Sierra & San Francisco Power Co.'s canal near 

La Grange, Calif., for the year ending September SO, 1925

NOTE. Natural mean discharge and run-oft determined by deducting water diverted from South Fork 

of Stanislaus River into the Middle Fork and correcting for storage in Relief Reservoir.

STANISLAUS RIVER NEAR KNIGHTS FERRY, CALIF.

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

2 miles above Goodwin Dam, and 6 miles above Knights Ferry, Stanislaus

County.

DRAINAGE AREA. Not measured. 

RECORDS AVAILABLE. December 18, 1915, to September 30, 1925. 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. Point of zero flow, gage height 0.6 foot. Control

is completely drowned out above stage of 5 feet.
STANISLAUS RIVER BASIN 213

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

recorder, 12.63 feet at 10.30 a. m. February 6 (discharge, 25,200 secondfeet); minimum stage, 0.90 foot at 7 p. m. October 21 (discharge, 25 secondfeet).

1903-1914: Maximum stage recorded, 26.0 feet at 4 a. m. January 31, 

1911 (discharge, 60,000 second-feet); no flow December 3-5, 1912.

1915-1925: Maximum stage recorded, that of February 6, 1925; minimum

stage recorded, 0.88 foot at 7 a. m. July 15, 1924 (discharge, 21 second-feet).

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

Water is also diverted from South Fork into Tuolumne Basin and from

North Fork through Utica Gold Mining Co.'s canal for use near Murphy

and Angels. The water diverted for 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 Fork, North Fork, and South Fork.

ACCURACY. Stage-discharge relation changed April 16. Bating curves well 

defined below 1,500 second-feet, fairly well defined between 1,500 and 5,000 

second-feet, and extended above. Water-stage recorder record excellent, 

except November 21-26, when clock stopped. Daily discharge ascertained 

by applyiag-siefta daily gage hfcigfet to rating table, except Febrtrary 6, 

for whiuil-^iowrly discharge was aw rageSy «ad the period November 21-26, 

for which it was estimated at 400 second-feet. Records good below 1,500 

second-feet and fair above.

The following discharge measurements were made: 

April 1, 1925: Gage height, 3.32 feet; discharge, 2,720 second-feet. 

April 1, 1925: Gage height, 3.30 feet; discharge, 2,680 second-feet. 

May 13, 1925: Gage height, 3.80 feet; discharge, 3,860 second-feet.

MOKELUMNE RIVER AT WOODBRIDGE, CALIF.

LOCATION. In NE. ^ NE. ^ sec. 34, T. 4 N., R. 6 E., at highway bridge, a

quarter of a mile northeast of Woodbridge, San Joaquin County. 

DRAINAGE AREA. Not measured. 

RECORDS AVAILABLE. May 27, 1924, to September 30, 1925 (low-water records

only). 

GAGE. Water-stage recorder in wooden well and shelter on left bank 100 feet

below bridge.

DISCHARGE MEASUREMENTS. Made from bridge or by wading. 

CHANNEL AND CONTROL. Channel is shifting sand. Stream meanders through a

deep sluggish channel. Control indefinite. 

EXTREMES OF DISCHARGE. 1924-1925: Minimum stage during period, from

water-stage recorder, 1.38 feet at 8 a. m. September 3, 1924 (discharge, 0.9

second-foot).

ACCURACY. Stage-discharge relation not permanent. Standard rating curves 

fairly well defined. Water-stage recorder record excellent, except November 

8-17 and July 27, whenllashboards were removed from the dam above, causing a rise in the stream and submerging the water-stage recorder. Daily 

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

using shifting-control method, except October 30, for which hourly discharge 

was averaged. Records good.

SACRAMENTO RIVER NEAR RED BLUFF, CALIF.

LOCATION. In lot 4, sec. 34, T. 28 N., R. 3 W., at lower epd 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 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, 1925. In 1879 the 

State engineer and in 1893 and 189W"the commissioner "of piifoHe worice 

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.

DISCHARGE MEASUREMENTS. Made from cable at gage.

CHANNEL AND CONTROL. Coarse gravel and small boulders; practically 

permanent.

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

recorder, 25.18 feet at 9 p.m. February XI (discharge, 156,000 second-feet); 

minimum stage, from water-stage recorder, 0.10 foot at 3 p. m. July 11 

(discharge, 2,810 second-feet).

1902-1925: Maximum stage recorded, 35.2 feet February 3, 1909 (discharge, 278,000 second-feet); minimum stage, from water-stage recorder, 

0.06 foot at 3 p. m. August 12, 1924 (discharge, 2,720 second-feet).

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

from some of the tributaries for irrigation.

REGULATION. A small diurnal fluctuation at low water is caused by operation 

of power plants of Pacific Gas & Electric Co. on Pit River.

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

defined. Water-stage recorder record excellent. Daily discharge ascertained by applying mean daily gage heigfit'tb rating table, except October 

28, November 9-10, and 20, for which hourly discharge was averaged, and 

January 21, for which it was interpolated. Records excellent. 

17690 29 WBP 611 16
234 SURFACE WATER SUPPLY, 1925, PART XI

The following discharge measurements were made:

February 8, 1925: Gage height, 16.85 feet; discharge, 78,500 second-feet.

September 10, 1925: Gage height, 0.62 foot; discharge, 3,840 second-feet.

LOCATION. At county bridge at Me Arthur, Shasta County.

RECORDS AVAILABLE. December 1, 1923, to September 30, 1925.

GAGE. Staff gage attached to downstream side of right abutment of bridge,

about 200 feet above gates controlling canal spillway to Pit River.

250 SURFACE WATER SUPPLY, 1925, PAET XI

CHANNEL AND CONTROL. Channel has been cut through fine soil. Spillway gates 

200 feet below gage control stage-discharge relation.

DIVERSIONS. The canal diverts from the headwaters of Fall River, one heading 

at Tule Lake and another at Tule River, and its lower end spills into Pit 

River. It has a very flat gradient and may be used both for irrigation and 

drainage by manipulation of checks and spillway gates.

REGULATION. The flow of the canal is entirely regulated by headgates, checks 

and spillways. .

ACCURACY. On account of the regulation below gage and moss in channel stagedischarge relation changes continually. Daily discharge given is the result 

of the current-meter measurement for the day and may not be the mean 

discharge for the day. Records fair.

COOPERATION. Results of discharge measurements furnished by the Mount 

Shasta Power Corporation.

The canal is used both for irrigation and drainage of lands on the north side 

of Pit River near McArthur. Below the gage a small amount of water is taken 

from the canal for irrigation on the south side of Pit River and also about 3 

second-feet to supply the local hydroelectric plant.

MIDDLE FORK OF AMERICAN RIVER NEAR EAST AUBURN, CALIF.

LOCATION. In SE. % sec. 6, T. 12 N., R. 9 E., at Mountain Quarry Co.'s plant, 

13^ miles above junction with North Fork of American River, and S% miles 

northeast of East Auburn, Placer County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. October 22, 1911, to September 30, 1925.

GAGE. Staff in four sections on left bank at pump house; read by J. A. Collins.

DISCHARGE MEASUREMENTS. Made from cable 700 feet below gage or by wading.

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

Banks high and not subject to overflow.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 25.0 feet at 

7.30 a. m. February 6 (discharge, about 36,300 second-feet); minimum stage, 

1.84 feet October 1-3 (discharge, 23 second-feet).

1911-1925: Maximum stage recorded, that of February 6,1925; minimum 

discharge recorded, 23 second-feet September 26 to October 3, 1924.

DIVERSIONS. Pilot Creek ditch diverts from Pilot Creek for irrigation on 

Georgetown divide. Little South Fork ditch diverts from Gerle Creek and 

discharges into Pilot Creek drainage basin where it is used when necessary 

to supplement the flow in Pilot Creek ditch; maximum discharge is probably less than 20 second-feet.

HEGTTLATION. Storage is developed in Loon Lake at the head of Gerle Creek to 

serve the ditches mentioned in the preceding paragraph.

ACCURACY. Stage-discharge relation changed February 7. Rating curves fairly 

well defined below 5,000 second-feet and extended above. Staff gage read to 

quarter-tenths twice daily except December 25, 28, February 1, 15, 22, 

March 1, 8, 15, 29, April 5, May 10, 17, 24, 31, June 7, 14, 21, 28, July 26, 

August 2, 9, 16, 23, 30, September 6, 13, 20, 27. Daily discharge ascertained 

by applying mean daily gage height to rating table except for days when 

gage was not read, for which it was estimated by comparison with records 

for North Fork of American River. Records good.

SOUTH FOBK OF AMERICAN BIVEB NBAS CAMINO, CALIF.

LOCATION. In NE. ^ SW. ^ sec. 25, T. 11 N., R. 11 E., 1 -mile below intake 

of Western States Gas & Electric Co.'s flume, 300 feet above mouth of Iowa 

Canyon Creek and 3 miles northwest of Camino, Eldorado County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. October 30, 1922, to September 30, 1925.

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

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

CHANNEL AND CONTROL. Channel is solid rock and boulders, with large pool 

at gage. Control is solid rock and boulders; permanent.

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

recorder, 19.0 feet at 7 a. m. February 6 (discharge, 18,000 second-feet);

minimum stage, 0.68 foot at noon October 27 (discharge, 3.7 second-feet).

1922-1925: Maximum stage, that of February 6, 1925; minimum stage,

that of October 27, 1924.

DIVERSIONS. Echo Lake flume diverts water from Echo Lake into South Fork 

of American River above station. El Dorado Canal diverts water for power 

and irrigation from the river above the station. Water used for power is 

returned to the river above the station, but about 40 second-feet is diverted 

for irrigation from May to October. Summerfield ditch diverts about 10 

second-feet from Slab Creek, and this is used for power below station. 

Western States Gas & Electric Co.'s flume diverts water 1 mile above gage 

for use for power.

REGULATION. Flow partly regulated by storage reservoirs above and by operation of Western States Gas & Electric Co.'s power plant, about 3 miles above.

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

below 6,700 second-feet. Water-stage recorder record good except August 

19-22. Daily discharge ascertained by applying mean daily gage height to 

rating table, except July 1 to September 30, for which discharge integrator 

was used, and October 28, November 9, February 4-7, for which hourly discharge was averaged. For periods of no gage-height record discharge was 

estimated by comparison with records for Silver Creek and El Dorado Canal.

of El Dorado Canal, three-fourths mile above mouth, and 2 miles southeast 

of Whitehall, Eldorado County.

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

RECORDS AVAILABLE. October 1, 1922, to September 30, 1925.

GAGE. Water-stage recorder on right bank. Previous to July 23, 1924, record 

was obtained from a staff gage on right bank, 30 feet below recorder.

DISCHARGE MEASUREMENTS. Made from a plank across creek at gage or by 

wading.

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

steep and not subject to overflow. Control, solid granite and permanent, 

except as it may be slightly influenced by changes in piers of old flume 

trestle.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, from waterstage recorder, 4.95 feet at 3 a. m. February 6 (discharge, 715 second-feet); 

minimum stage from water-stage recorder, 0.85 foot October 1 and 2 

(discharge, 0.2 second-foot).

1922-1925: Maximum stage, that of February 6,1925; minimum discharge 

recorded, 0.1 second-foot August 28 to September 2, 1924.

ICE. Float frozen in well December 19-29 and January 9-16.

DIVERSIONS. None.

ACCURACY. Stage-discharge relation changed February 6, owing to damage by 

high water to trestle piers of old flume in gage pool. Rating curves well 

defined. Water-stage recorder record good except December 2-6, March 

14-23, August 19-29, and when affected by ice. Daily discharge ascertained 

by applying mean daily gage height to rating table, except November 9 and 

February 4-6, for which hourly discharge was averaged. For periods of no 

gage-height record or when affected by ice, discharge estimated by comparison with records for Plum Creek and South Fork of American River. 

Records good.

106 second-feet); water is usually turned out of canal part of each day. 

DIVERSIONS. Water is diverted into Finnon Reservoir from One Eye Creek,

through One Eye ditch and from Slab Creek through Summer-field ditch. 

REGULATION. Flow completely regulated by gates in dam at Finnon Reservoir. 

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

Staff gage read to hundredths before and after regulation. Mean daily

discharge ascertained by reducing results obtained by applying gage height

for part of a day to rating table. Records good.

No discharge measurements were made during the year.

328 SURFACE WATER SUPPLY, 1925, PART XI

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

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

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

Mendocino County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. November 18, 1909, to September 30, 1925. (Monthly 

discharge only for 1909-1922.)

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

equalizing reservoir about 800 feet above Van Arsdale Dam.

DISCHARGE MEASUREMENTS. Measurements in 1919 were made from a suspension bridge below dam.

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

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

on crest. Crest of flashboards is very uneven. Average elevation in 1925 

was 4.22 feet for first part of year and 4.6 feet last part. Length of crest 

about 286 feet. A sluice gate in bottom of dam is opened only when stage is 

rising rapidly or when reservoir is emptied. Reservoir is an enlargement 

of the natural stream and is about 400 feet wide and a mile or more long 

and is fairly well filled with sand and aquatic plants.

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

recorder, 7.80 feet with flashboards on part of dam and sluice gate open at 

1 p. m. February 18 (discharge, 17,800 second-feet). Maximum discharge, 

including flow through power house at Potter Valley, 18,100 second-feet. 

Minimum discharge, wasted down South Eel River, about 2 second-feet.

DIVERSIONS. Water diverted through a tunnel to the power house of Snow 

Mountain Water & Power Co. in Potter Valley and then wasted down a 

branch of Russian River.

REGULATION. Entire flow regulated at Lake Pillsbury. Flow diverted to power 

house except about 2 second-feet, which is wasted down South Eel River 

through the fishway and sluice gate.

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

dam. Rating curve well defined. Gage height record good. Daily discharge ascertained by applying hourly gage height to rating table after 

subtracting average height of flashboards from the gage height. When sluice 

gate was open, 700 second-feet were added to give total daily discharge. 

Records fair.

No discharge measurements were made during the year.

Daily discharge, in second-feet, of South Eel River at Van Arsdale Dam, near Potter 

Valley, Calif., for the year ending September SO, 1925

LOCATION. In west % NW, ^ sec. 6, T. 17 N., R. 11 W., at power house of 

Snow Mountain Water & Power Co., 3 miles northwest of Potter Valley, 

Mendocino County.

RECORDS AVAILABLE. October 1, 1922, to September 30, 1925.
332 SURFACE WATER SUPPLY, 1925, PART XI

GAGE. Water-stage recorder in stilling well on left bank of tailrace about 100 

feet below power house, installed October 1, 1923. Previous gage was a 

float gage in same well. Datum not changed.

DISCHARGE MEASUREMENTS. Made from a plank across tailrace just below 

gage.

CHANNEL AND CONTROL. Three individual tailraces from units Nos. 1, 3, and 4 

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

are concrete. Tailraee is rectangular, 12 feet wide and 8 feet deep. Control is an 8 by 12 inch plank placed in weir guides to form a submerged 

weir.

EXTREMES OF DISCHARGE. Maximum mean daily discharge recorded during 

year, 317 second-feet January 14.

1922-1925: Maximum mean daily discharge recorded, 317 second-feet 

October 10-13, 1922, and January 14, 1925.

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

small ditches for irrigation in Potter Valley. Water was diverted at various 

times from October 1-17 and June 26 to September 30 but is included in 

table of daily discharge.

REGULATION. Completely regulated by operation at power plant.

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

defined. Water-stage recorder record excellent. Daily discharge ascertained 

by applying mean daily gage height to rating table, by use of discharge 

integrator, or by averaging hourly discharge. Records good.

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

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

The following discharge measurement was made: 

March 2,1925: Gage height, 3.26 feet; discharge, 300 second-feet.

minimum stage, 1.05 feet, about August 20 (discharge, 18 second-feet).

1917-1925: Maximum discharge, 1,220 second-feet April 13, 1919. The 

flood of April 27 or 28, 1917, had an estimated discharge of 2,500 secondfeet. Minimum discharge, 14 second-feet June 19-21, 1924.

ICE. Stage-discharge relation probably affected by ice December 18-27; 

recorder not operating, discharge estimated.

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

by natural flooding, and smaller areas by ditches.

REGULATION. None.

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

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

obtained by inspecting recorder graph. Records good, except for November, 

August, and September, for which they are fair.

UNE RIVER AT EIAMATH FAILS, OREG.

LOCATION. In NW. ^i sec. 32, T. 38 S., R. 9 E., 200 yards above outlet of Keno 

Canal, three-eighths mile above county bridge over Link River at Klamath 

Falls, Klamath County, and 1 mile below outlet of Upper Klamath Lake.

DRAINAGE AREA. 3,800 square miles (revised; measured on topographic and 

Forest Service map).

RECORDS AVAILABLE. May 15, 1904, to September 30, 1925. The location of 

this station has been changed from time to time, but the records always 

represented the flow under the county bridge.

GAGE. Stevens eight-day water-stage recorder on left bank above outlet of Keno 

Canal; recorder inspected and staff gage read daily by employee of California Oregon Power Co.

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

at low water. To refer measurements made at bridge to gage above outlet 

of Keno Canal, the measured discharge at bridge is reduced by the measured or computed discharge of Keno Canal.

CHANNEL AND CONTROL. Bed at bridge composed of mud and sand, with some 

boulders on left side. Rock and boulder riffle, a short distance below gage 

and above outlet of Keno Canal, forms practically permanent control for 

present gage.

EXTREMES OF DISCHARGE. Maximum combined discharge of Link River and 

Keno Canal, 2,350 second-feet at 4 p. m. April 30; minimum combined discharge 148 second-feet at 10.30 a. m. February 7.

1904-1925: Maximum stage, 7.30 feet at gage at bridge May 12,1904 

(discharge, 9,400 second-feet); minimum stage, 4.07 feet, August 30, 1918 

determined by leveling (discharge estimated at 22 second-feet).
338 SURFACE WATER SUPPLY, 1925, PAET XI

ICE. Stage-discharge relation not affected by ice.

DIVBKSIONS. After April 15 the main or "A" canal of the Klamath project of 

the United States Bureau of Reclamation diverted water from Link River 

immediately below Upper Klamath Lake. Keno Canal of California Oregon 

Power Co. diverts around the present gage, but the flow of the canal is 

included in the record for Link River. (See p. 359.) Some water is also 

diverted for irrigation from the tributaries of Upper Klamath Lake, but the 

total run-off is as yet only slightly affected.

REGULATION. Water stored in Upper Klamath Lake by dam beginning April 

15, 1919.

ACCTTKACY. Stage-discharge relation practically permanent. Rating curve well 

defined at all ordinary stages, and based on discharge measurements made 

at the county bridge and reduced by flow of Keno Canal. Operation of 

water-stage recorder satisfactory, except for short periods. Daily discharge 

ascertained by applying to rating table mean daily gage height obtained by 

inspection of recorder graph and adding the flow in the Keno Canal. Discharge estimated February 24, June 24-26, August 27-28, and September 10, 

12-15, on basis of daily gage reading, or incomplete gage height record, and 

kilowatt-hour output of east side power plant. Records excellent except 

for short periods, for which they are fair.

The following discharge measurements were made:

December 3, 1924: Gage height, 2.30 feet; discharge, 2,030 second-feet.

September 23, 1925: Gage height, 2.18 feet; discharge, 1,960 second-feet.

Daily discharge, in second-feet, of Link River at Klamath Falls, Oreg., for the year

ending September SO, 1925

LOCATION. In SW. J^ sec. 31, T. 39 S., R. 7 Er , at Spencer Bridge, 1 mile below 

Spencer Creek, 6 miles below former station at Keno, and 18 miles west of 

Klamath Falls, Klamath County.

DRAINAGE AREA. 4,000 square miles (revised; measured on topographic and 

Forest Service maps). j

RECORDS AVAILABLE. October 7, 1913, to September 30, 1925. Records at 

Keno May 31, 1904, to December 31, 191o.

GAGE. Stevens continuous water-stage recorder on right bank about 500 feet 

below bridge used since October 1, 1923; inspected by B. K. Robinson.

DISCHARGE MEASUREMENTS. Made from upstream side of bridge or by wading.

CHANNEL AND CONTROL. Narrow channel, confined by rock crib and timber 

of former bridge; practically permanent.

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

year, 4.78 feet at noon January 7 (discharge, 2,340 second-feet); minimum 

stage, from water-stage recorder, 1.61 feejt at 8.30 p. m. February 7 (dis 

charge, 594 second-feet).

1913-1925: Maximum discharge, 5,130 (second-feet April 21, 1914; minimum discharge, 371 second-feet June 14,1924. A stage of 15.3 feet (discharge, 9,250 second-feet) occurred at Ke:io station about May 10, 1904.
340 SURFACE WATER SUPPLY, 1925, PART XI

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. Only a small quantity of water diverted below Klamath Falls 

station. Practically all the flow of Lost River during the nonirrigating 

season is diverted into Klamath River below Klamath Falls by the Lost River 

diversion canal (p. 361).

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 permanent. Rating curve well defined 

between 700 and 2,200 second-feet. Operation of water-stage recorder 

satisfactory, except December 20 to January 5, when float was frozen in 

well. Daily discharge ascertained by applying to rating table mean gage 

height obtained by inspection of recorder graph. Records good.

EIAMATE RIVER NEAR COfCO, CALIF.

LOCATION. In NW. }£ sec. 31, T. 48 N., R. 14 W., a quarter of a mile above 

mouth of Fall Creek, 2 miles below the California Oregon Power Co.'s Copco 

plant and half a mile south of Copco post office, Siskiyou County, Calif.

DRAINAGE AREA. 4,300 square miles (measured on topographic and Forest 

Service maps).

RECORDS AVAILABLE. October 1, 1923, to September 30, 1925.

GAGE. Stevens continuous water-stage recorder on right bank; inspected by 

operator at Fall Creek plant of California Oregon Power Co.

DISCHARGE MEASUREMENTS. Made from cable 20 feet above gage.

CHANNEL AND CONTROL. Bed composed of coarse gravel, some large boulders, 

and bedrock; practically permanent. Banks high, with some brush.

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

recorder, 5.15 feet at 3 p. not. August4 (discharge, 4,100 second-feet); mini-

, mum discharge due to complete shutdown of plant at Copco, about 10

second-feet. This occurred frequently, both units shut down for about 8

hours each night July 6 to August 3.

1924-1925: Maximum stage from recorder, 5.85 feet January 2, 1924 (discharge, 4,880 second-feet); minimum, that of 1925.

ICE. None.

DIVERSIONS. One small diversion on left bank around station.

REGULATION. Discharge is regulated by storage in upper Klamath Lake and 

California Oregon Power Co.'s reservoit above plant at Copco No. 1. 

When no water is going over dam, the discharge varies with the load on the 

power plant. Practically no pondage above diversion dam of Copco No. 2, 

but operation of radial gates may cause sudden fluctuation of short duration.

ACCURACY. Stage-discharge relation changed between July 6 and August 3, by 

excavation past gage and control of tailra.ce of Copco hydroelectric plant 

 No. 2. Rating curves well defined for periods before and after these dates. 

Operation of water-stage recorder satisfactory except November 8, January 

11, June 1-27, July 12 to August 2, September 8, 9, and 18. Relation curve 

of discharge to electrical output well defined. Daily discharge ascertained 

by use of discharge integrator except for iperiods noted above, for which it 

was obtained from the electrical output. Records excellent.

LOCATION. In NE. M sec. 13, T. 46 N., R. 12 W., above highway bridge, 300 

feet above mouth of Walker Creek, 1J^ miles southeast of Seiad Valley, 

Siskiyou County, and llj^ miles below mouth of Scott River.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. November 23, 1912, to June 30, 1925, when the station 

was discontinued.

GAGE. Staff in five sections on left bank one-fourth mile above highway bridge; 

read by M. J. Brickley.

DISCHARGE MEASUREMENTS. Made from cable 35 feet below gage.

CHANNEL AND CONTROL. Gravel and boulders; fairly permanent. Banks are 

high and not subject to overflow.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 12.7 feet at 

5 p. m. February 4 (discharge, 23,700 second-feet); minimum stage recorded, 

2.1 feet October 6 (discharge, 480 second-feet).

1912-1925: Maximum stage recorded, 13.3 feet at 9.30 p. m. December 

31, 1913 (discharge, from extension of rating curve, about 26,500 secondfeet); minimum stage recorded, 2.05 feet November 25, 1917 (discharge, 

about 320 second-feet).

DIVERSIONS. Water is diverted from main river and tributaries above station 

for use in irrigation, placer mining, and power developments.

REGULATION. Low-water flow affected by operation of power plant above.

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

defined above 900 second-feet. Staff gage read to tenths once daily. 

Daily discharge ascertained by applying mean daily gage height to rating 

table. Records good at high water and only fair at low water owing to 

regulation from power plants above.

No discharge measurements were made during the year.

Daily discharge, in second-feet, of Klamath River near Seiad Valley, Calif., for the

KENO CANAL AT KLAMATH FALLS, OREG.

LOCATION. In NE. % sec. 31, T. 38 S., R. 9 E., 200 feet above penstock to west 

side plant of California Oregon Power Co., one-fourth mile above Link 

River bridge at Klamath Falls, Klamath County.

RECOKDS AVAILABLE. October 1, 1923, to September 30, 1925.

GAGE. Vertical staff gage on left bank of canal; integrating watt-hour meter 

and indicating wattmeter in power house; read by employees of California 

Oregon Power Co.

DISCHARGE MEASUREMENTS. Made from footbridge at gage. The measured 

discharge in second-feet is referred to the load in kilowatts.

CHANNEL AND CONTROL. Smooth earth bottom, high banks, and swift, even 

current at measuring section. Stage is controlled by load on turbines of 

power plant.

EXTREMES OF DISCHARGE. Not possible to determine maximum momentary 

discharge. Maximum daily discharge, 276 second-feet March 14; canal dry 

February 17 to March 5.

DIVERSIONS. Spillway from canal to river 300 feet above power plant was in 

use about 50 days, but the total waste probably did not exceed 1,000 acrefeet, and has been disregarded.

REGULATION. The flow is controlled by gates at head of canal, which are regulated to supply water for power plant.
360 SURFACE WATER SUPPLY, 1925, PART XI

ACCURACY. Kilowatt-discharge relation apparently changed during year for 

discharges above 190 second-feet. Curves of relation used as follows: 

October 1 to February 15, well denned; for March 6 to September 30, fairly 

well defined. Integrating watt-hour meter read to hundredth^ of kilowatthours once daily at midnight. Records good.

Keno Canal diverts water from Upper Klamath Lake at the Link River 

storage dam in SE. 34 sec. 30. Water is used for developing power and returned 

to Link River in NE. J4 sec. 31.

' IOST RIVER DIVERSION CAKTAI KTEAR OIEBTE, OREG.

LOCATION. In SE. J^ sec. 30, T. 39 S., R. 10 E., a quarter of a mile below intake 

of canal at Lost River Dam, 4 miles below Olene, Klamath County.

RECORDS AVAILABLE. March 14, 1912, to September 30, 1925.

GAGE. Water-stage recorder on right bank about 100 yards below spillway from 

the "C-G" canal, beginning May 4, 1923; vertical staffs showing height of 

water in pond back of head gates and in canal below gates also read once 

a day.

CHANNEL. AND CONTROL. Wide shallow canal, excavated in sand and silt; 

backwater from Klamath River extends practically to head of canal.

DISCHARGE MEASUREMENTS. Made from a footbridge a short distance below 

head gate or from wagon bridge at gage.

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

recorder, 4.17 feet on October 30 (discharge, 316 second-feet). Canal 

practically dry August 18-24.

1912-1925: Maximum discharge recorded, 508 second-feet February 28, 

1914.

DIVERSIONS. Beginning in June, 1922, water has been wasted from "C-G" 

canal into the diversion canal, the amount of which has been estimated. 

Beginning May 4, 1923, the station was located below wasteway.

ACCURACY. Stage-discharge relation at recorder site unstable on account of 

varying backwater from Klamath River and growth of aquatic plants. 

Fairly well defined rating curve used February 14 to April 7; shifting-control method used rest of year; daily discharge ascertained by applying to 

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

Discharge computed using gates of Lost River dam as orifices April 28, 

May 15-18, August 10-17, and 25. Records fair.

COOPERATION. Records furnished by United States Bureau of Reclamation.

Lost River diversion canal diverts from Lost River in SW. J4 sec. 29, T. 39 S.* 

R. 10 E., and discharges into Klamath River in SW. ^ set:. 17, T. 39 S.,R. 9 E. 

The discharge of Lost River during the nonirrigation season has been diverted 

into Klamath River beginning in 1912 to assist in the reclamation of the bed of 

Tule Lake. Most of the water discharged during October, 1924, was released 

from storage at the Clear Lake Reservoir near the head of Lost River.

into Bear Creek Basin by Talent Irrigation District. Practically no irrigation 

within the basin. Two small ditches divert water around gage.

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

defined below 350 second-feet. 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. 

Discharge estimated November 10-12, December 15-25, August 5-9, and 

12-18. Records good, except for estimated periods and periods when discharge was above 350 second-feet, for which they are fair. 

The following discharge measurements were made: 

April 17, 1925: Gage height, 3.23 feet; discharge, 308 second-feet. 

August 10, 1925: Gage height, 0.55 foot; discharge, 3.1 second-feet.
