SUEPACE WATER SUPPLY OP PACIFIC SLOPE BASINS 

IN CALIFORNIA, 1917.

AUTHORIZATION AND SCOPE OF WORK.

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

measurements of flow of streams in the United States during the 

year} ending September 30, 1917.

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 30, 1895-1918.

In the execution of the work many private and State organizations 

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

data. Acknowledgments for cooperation of the first kind are made 

in connection with the description of each station affected; cooperation of the second kind is acknowledged on page 13.

Measurements of stream flow have been made at about 4,500 

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

the Hawaiian Islands. In July, 1917, 1,180 gaging stations were 

being maintained by the Survey and the cooperating organizations.

EXPIiANATION OF DATA.

The data presented in this report cover the year beginning October 

1, 1916, and ending September 30, 1917. At the first of January 

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

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

snow, 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 a 

year beginning October 1 is practically all derived from precipitation 

in that year.

The base data collected at gaging stations (PL I, B) 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 

(PL II) that gives a continuous record of the fluctuations. Measurements of discharge are made with a current meter by the general 

methods outlined in standard textbooks on the measurement of river 

discharge.

From the discharge measurements, rating curves and tables are prepared that give the discharge for any stage, and these rating tables, 

when applied to the gage heights, give the daily discharge from which 

the monthly and yearly mean discharge is determined.

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

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

ords 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 constancy of the stage-discharge relation, 

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

for log driving, shifting of channel, 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 TmninrniTn 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 

fluctuation the" discharge obtained from the rating table and the
12 SURFACE WATER SUPPLY, MM, PART XI.

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 is obtained by averaging the discharge at 

regular intervals during the day or by use of 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 for each second during the month. On 

this average flow computations recorded in the remaining columns, 

which are defined on page 10, are based.

ACCURACY OP PIEIiD DATA AND COMPUTED RECORDS.

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 or a footnote added 

to the table gives information regarding (1) permanence of the stagedischarge relation, (2) precision with which the discharge rating curve 

is defined, (3) refinement of gage readings, (4) frequency of gage 

readings, and (5) methods of applying daily gage height to the rating 

table to obtain the daily discharge. For the rating tables "well 

defined" indicates, in general, that the rating is probably accurate 

within 5 per cent; "fairly well defined," within 10 per cent; "poorly 

defined," within 15 to 25 per cent. These notes are very general and 

are based on the plotting of the inclividual measurements with reference to the mean rating curve.

The monthly means for any station may represent with high 

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

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

may be subject to gross errors caused by the inclusion of large noncontributing districts in the measured drainage area, by lack of 

information concerning water diverted for irrigation or other use, 

or by inability to interpret the effect of artificial regulation of the 

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

and "run-off (depth in inches)" are therefore not computed if such 

errors -appear probable. The computations are also omitted for 

stations on streams draining areas in which the annual rainfall
COOPEKATIOIT. . '13

is less than 20 inches. All figures representing "second-feet per 

square mile" and "run-off (depth in inches)" previously published 

by the Survey should be used with caution because of possible inherent but unknown sources of error.

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 table 'of daily discharge allows more detailed 

study of the variation in flow. It should be borne in mind, however, that the observations in each'succeeding year may be expected 

to throw new light on data previously published.

COOPERATION.

Investigation of the water resources of California is being carried 

on by the United States Geological Survey, in cooperation with the 

State in accordance with acts of the State legislature, approved 

March 16, 1903, March 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 1916-17 

was maintained in accordance with the contract approved by the 

State board of control and 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 are W. A. Johnstone, president; Irving 

Martin and A. E. Chandler, commissioners; W. D. Stephens, governor; and W. F. McClure, State engineer. Josephine A. Patten is 

secretary.

The entire expense of the stream-flow investigations in Tuolumne 

River drainage for the Hetch Hetchy project is paid by the city and 

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

All stations in Los Angeles County, except on San Gabriel River, 

are maintained in accordance with a contract between the Board of 

Supervisors and the Department of Agriculture, represented by the 

Forest Service through F. H. Fowler, engineer, district No. 5, and the 

Weather Bureau through Ford A. Carpenter, meteorologist. Los 

Angeles County pays all expenses of the field work except services 

furnished by the Forest Service, Weather Bureau, and Geological Survey. The Geological Survey has supervision of the work and compiles 

all field data for publication.

Assistance in the maintenance of river-measurement stations was 

furnished by the United States Forest Service, through F. H. Fowler, 

engineer, district No. 5; United States Weather Bureau, through Ford 

A. Carpenter and N. R. Taylor, meteorologists; United States Indian

Dennis, construction engineer; the Turlock, Modesto, Oakdale, and 

South San Joaquin irrigation districts.

Many complete estimates of run-off, gage height records, and discharge measurements are furnished by various federal bureaus, private companies, and individuals who are interested in the water 

resources of California. This cooperation is acknowledged and explained in the descriptions that precede the records. ; .

The work in Oregon was carried on under a cooperative agreement 

with the State through John H. Lewis, State engineer. Financial 

cooperation was also furnished by the Goose Lake Valley Irrigation 

Co. and the Talent Irrigation District.

BOULDER CREEK AT CTTTAMACA RESERVOIR, 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 Cyeek.

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

RECORDS AVAILABLE. June 19, 1912, to September 30,1917. '

GAGE. Vertical staff fastened to 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.

CHANNEL AND CONTROL. Cippoletti weir acts as permanent control.

EXTREMES OF DISCHARGE. Maximum daily discharge reported during year, 9.9, 

second-feet July 11; no water released from reservoir except when needed for 

Cuyamaca Water Co. 's flume.

1912-1917: Maximum daily discharge recorded, 1,877 second-feet, January 28 

1916.'

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 except when changes are made in 

weir. Gage read daily to hundredths with additional observations when reservoir 

gates are changed. Records excellent when discharge does not exceed capacity 

of weir.

COOPERATION. Record of daily discharge furnished by Cuyamaca Water Co

The following discharge measurement was made by D. A. McClung: 

June 28, 1917: Gage height, 0.35 foot; discharge, 4.8 second-feet.

Daily discharge, in second-feet, of Boulder Creek at Cuyamaca reservoir, near Julian, Calif., 

for the year ending Sept. 30, 1917.

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

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

about 13 miles northeast of Lakeside, San Diego County.

RECORDS AVAILABLE. May 4, 1912, to September 30, 1917.

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

intake; installed April 8, 1916. Previous gage was similar but was 500 feet 

below intake and just above sand box. Datum has always been elevation of 

floor of flume. Gage read by employees of Cuyamaca Water Co.

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

CHANNEL AND CONTROL. The flume is lined with tar paper to reduce leakage.

EXTREMES OF DISCHARGE. Maximum daily discharge 1912-1917 was 51 second-feet, 

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

ACCURACY. Stage-discharge relation permanent throughout year. Rating curve 

well defined. Gage read to hundred the three times daily. Daily discharge 

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

Cuyamaca Water Co.'s flume diverts water from San Diego River and receives 

through South Fork flume water from South Fork of San Diego River. The flume 

is 6 feet wide, 24 inches deep, and more than 30 miles long. It carries water 

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. Water was again furnished the 

city of San Diego after the floods, January, 1916. It now supplies water for irrigation of about 4,000 acres, and 7 per cent of the flow is used for domestic service. 

The Capitan Grande Indian Reservation has a water right of 0.8 second-foot from 

this flume.

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

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

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

intake on Sam Diego River.

RECORDS AVAILABLE. January 1, 1907, to September 30, 1917.

GAGE. Vertical staff in a stilling box fastened to outside of flume just below patrolman's cabin at same site as water-stage recorder used in previous years. Position 

of gage has been changed slightly several times since station was first established, 

but datum has always been same as elevation of floor of flume. Gage read by an 

employee of Cuyamaca Water Co.
SAN DIEGO RIVER BASIN. 21

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

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

more tar-paper lining was put in. Elevation of flume appears to vary slightly with 

quantity of water flowing.

EXTREMES OP DISCHARGE. Maximum daily discharge, 1907^-1917, was 24 second-feet, 

May 10-12, 1916. No flow at certain times nearly every year.

DIVERSIONS. Water is diverted into the flume from South Fork of San Diego River 

and a small quantity is diverted from this flume at Capitan Grande Indian Reservation above station.

ACCURACY. Stage-discharge relation not permanent throughout the year owing to 

poor condition of tar-paper lining and growth of moss in flume. Two fairly well 

defined rating curves were used throughout the year except for period March 29 

to May 22. Gage read to hundredths three times daily. Daily discharge ascertained by applying mean daily gage height to rating table or by shifting-control 

method. Records fair.

Calif., page 19.

SAN DIEGTJITO RIVER BASEST. 

SANTA YSABEL CREEK! NEAR MESA GRANDE, CALIF.

LOCATION. In NW. f sec. 21, T. 12 S., R. 2 E., at Sutherland dam site, about 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).

RECORDS AVAILABLE. December 29, 1912, to September 30, 1917.

GAGE. Friez 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 site but original datum has not been 

maintained.

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

CHANNEL AND CONTROL. Bed composed of 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 high, covered with brush, and not 

subject to overflow.

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

3.17 feet at 1 a. m. February 23 (discharge, 510 second-feet); minimum stage 

from water-stage recorder, 1.05 feet at 7 p. m. September 2 (discharge, 0.3 

second-foot).

1912-1917: Maximum stage recorded, 11.0 feet January 27, 1916 (discharge, 

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

6-13, 1914.

DIVERSIONS. None of any importance above the station.

REGULATION. None.

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

.deposition of sand or its scouring out at the control. Control was repaired November 6-9. Several well-defined rating curves used. Operation of water-stage 

recorder satisfactory throughout the year. Daily discharge, except that for 

October 1-11 (estimated from measurements) and November 6-9 (interpolated), 

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

by inspecting recorder graph. Records fair.

SANTA YSABEL CREEK NEAR RAMONA, CALIF.

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

of Pamo Valley, 1J miles below mouth of Temescal Creek, and about 4£ miles 

north of Ramona, San Diego County.

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

RECORDS AVAILABLE. February 5, 1912, to September 30, 1917.

GAGE. Leitz water-stage recorder, with concrete well and house, on left bank at dam 

site; in operation January 22 to 30, 1917; vertical staff fastened to outside of gage 

well, known as gage "C," was used December 8 to January 21, and July 1 to September 30,1917. Gage "B " is a vertical staff fastened to solid rock on left bank a 

short distance above gage "C," installed January 31, 1916; it was used October 1 

to December 7, 1916. Gage read by C. M. DeVenelle. Original gage was a staff 

in four sections on left bank, one-half mile upstream, with a short vertical section 

at concrete control.

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

CHANNEL AND CONTROL. Bed composed of shifting sand. Banks 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. It was 

only partly effective during high water as a large boulder in the channel a few feet 

upstream caused a sand bar to form at control. This boulder was removed in 

September, 1917.

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

4.55 feet at 1 a. m. February 23 (discharge, determined from extension of rating 

curve, 2,540 second-feet); minimum stage, 1.05 feet at 7 p. m. September 2 (discharge, 0.3 second-foot). \

1912-1917: Maximum stage recorded, 14.0 feet at 7 p. m. January 27, 1916 (discharge, 28,400 second-feet); minimum stage, 0.74 foot October 1-6,1915 (discharge, 

0.1 second-foot).

DIVERSIONS. None of any importance above the station. Water is diverted from 

Santa Ysabel Creek near mouth of 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 below the intake of the East San Pasqual.

REGULATION. None.
SAN DIEGTTITO EIVER BASIN. 25

ACCURACY. Stage-discharge relation not permanent during year on account of formation of sand bar above control. Fairly well-defined rating curves used December 

8-23; January 3-18; April 16 to May 17; and May 24 to September 30. For these 

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

height determined by inspecting gage-height graph. Discharge October 1 to 

December 7 estimated from discharge measurements and record for Mesa Grande. 

For remainder of year, not covered by rating curves, discharge was computed by 

shifting-control method aind from curves covering short periods. October 1 to 

January 21 and July 1 to September 30 gage read to hundredths twice daily. 

Records fair for periods covered by rating curves; remainder of record roughly 

approximate.

LOCATION. In SE. J NW. i sec. 18, T. 13 S., R. 2 W., at Carroll dam site, 5£ miles 

below Bernardo bridge, about 10J miles above mouth of river and 4 miles southwest of Bernardo, Sa.n Diego County.

DRAINAGE ARE A.-sr-299" square miles (measured on topographic maps).

RECORDS AVAILABLE. January 17, 1916, to September 30, 1917.

GAGE. Vertical staff in four sections on right bank at dam site; read by E. A. Bartl 

and E. W. Case. Zero of gage 214 feet above sea level.

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

CHANNEL AND CONTROL. Shifting sand with bed rock outcropping about 400 feet 

below gage; fairly permanent except during low stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 4.50 feet at 7 a. m.

February 23 (discharge, 1,410 second-feet); stream dry June 30 to September 30.

1916-1917: Maximum stage recorded, 21.2 feet 1 to 3 p. m. January 27, 1916

(discharge, 72,100 second-feet); no flow July 30 to September 30, 1916, and June

30 to September 30, 1917.

DIVERSIONS. East and West San Pasqual ditches divert water from this stream for 

irrigation in San Pasqual Valley. There are also several pumping plants in this 

valley.

REGULATION. None.

ACCURACY. Stage-discharge relation not permanent except for short periods during 

ye£r. Changes in centrol fairly well defined by frequent discharge measurements. Fairly well defined rating curves used October 3 to December 1, January 

3-18, and May 9-June 29. Gage read to hundredths twice daily; frequent readings during high water. Daily discharge for periods covered by rating curves 

ascertained by applying gage height to rating table; discharge for remainder of 

year computed by shifting-control method from rating curves covering short 

periods. Records October to May good for channel of this type; records for June 

only fair, as no measurements were made during the month.

above Southern California Edison Colt 's Mentone plant, half a mile above mouth 

of Deep Creek, and 3J miles northeast of Mentone, San Bernardino County.

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

RECORDS AVAILABLE. July 1,1896, to September 30,1917.

GAGE. Vertical staff fastened to a rock ledge on left bank one-fourth mile above 

power house. Th(e gage was installed February 11, 1916, original datum not 

maintained. Record September 7-30, 1917, is from Gurley graph water-stage 

recorder at same location and datum. Gage used before February 11, 1916, was 

a vertical staff 10 feet upstream; destroyed by flood in January, 1916. Original 

gage was just above Wartn Springs Canyon, 1J miles upstream. Gage read by 

E. Givens.

DISCHARGE MEASUREMENTS. Made by wading near gage.

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

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 2.10 feet at 8 a. m. 

February 25 (discharge, 164 second-feet); minimum stage, 0.28 foot at 8 a. m. 

November 11 (discharge, JL.l second-feet).

1896-1917: Maximum discharge (stage not known, gage washed out) January 

27,1916, 29,100 second-feet; minimum discharge, 0.6 second-foot during parts of 

every month from October, 1913, to January, 1914 (stage, 2.3 feet).

DIVERSIONS. Water is diverted at Southern California Edison Co.'s plant No. 2, 2J 

miles above the gage for use at Mentone power house. The Greenspot pipe line 

diverts water for irrigation from the forebay at the Mentone power house. From 

the tailrace the water is carried across Santa Ana River and used for irrigation.

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

California Edison Go.'s power plants Nos. 1 and 2 are 5J and 2f miles, respectively, above the Menton^ plant.

ACCURACY. Stage-discharge relation permanent during year. Rating curve well 

defined. Gage read once a day to hundredths. Daily discharge October 1 to 

September 3 ascertained by applying gage height to rating table; September 7-30, 

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

gage-height graph. Records October 1 to September 6, fair; remainder of record 

good.

line on June 17. Discharge given above table for these days as well as for other days when discharge of 

canals was changed, may be subject to considerable error as the discharge given for river alone may not be 

the correct mean for the day. See pp. 40 and 41 for daily discharge of Southern California Edison Co.'s

NOTE. For monthly discharge tables for Southern California Edison Co.'s canal and Greenspot pipe 

line, see p. 41.
40 SURFACE WATER SUPPLY, 1017, PART XI.

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

HENTONE, CALIF.

LOCATION. At Southern California Edison Co.'s plant at mouth of canyon, 2f

miles below intake on Santa Ana Elver, and about 3 miles northeast of Mentone,

San Bernardino County.

RECORDS AVAILABLE. 1896 to September 30,1917. 

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

assumption that 1 second-foot develops 18.9 kilowatts. 

EXTREMES OF DISCHARGE. 1896-1917: Maximum mean daily discharge recorded,

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

DIVERSIONS. Water diverted from the fore bay by the Greenspot pipe line must be

added to give total flow of canal. From 1903 to 1911 pipe line diverted water

from canal above forebay and no discharge was reported. The present pipe line

was put in operation September 7, 1911.

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

2f miles above the Mentone plant at the mouth of the canyon. All 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 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..

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

Calif., for the year ending Sept. SO, 1917.

and 14 miles east of Redlands. 

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. September 23, 1903, to September 30, 1917. 

DISCHARGE. Obtained by combining results of current-meter measurements in

power canal with flow over diverting dam. The flow over diverting dam is only

roughly determined. 

EXTREMES OF DISCHARGE. 1903-1917: Maximum mean daily discharge reported,

368 second-feet February 20, 1914 (no record for flood of January, 1916); minimum

mean daily discharge reported, 7.0 second-feet November 19 and 20, 1904. 

DIVERSIONS. None. 

REGULATION. None. 

ACCURACY. Two sets of observations recorded each day at 6 a. m. and 6 p. m. When

total flow of Mill Creek is diverted into power canal records are considered good;

for higher stages they are roughly approximate. 

COOPERATION. Daily-discharge record furnished by Southern California Edison Co.,

through H. W. Dennis, construction engineer.

EXTREMES OF DISCHARGE. Maximum stage recorded during y^ar, 8.0 feet at 4 p m. 

December 24 (discharge determined from extension of rating; curve, 3,900 secondfeet) ; channel dry at gage for several months during year.

1894-1917: Maximum stage recorded, 12.0 feet January

40,000 second-feet); channel dry ft>r several months each year. 

DIVERSIONS. Southern California Edison Co.'s power canal Itieads about 5 miles

above station. Water was diverted through the tunnel about 600 feet above

ford, beginning April 1, 1917. 

REGULATION . None. 

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

defined. Gage read to hundredtks once a day. Daily discharge ascertained by

applying daily gage height to rating table. Records for October and December

roughly approximate; fair for remainder of year.

of power canal see table, p. 57.

SOUTHERN CALIFORNIA EDISON CO.'S CANAL NEAR AZTTSA, CALIF.

LOCATION. At Southern California Edison Co.'s power house, 9 miles below intake 

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

RECORDS AVAILABLE. 1896 to September 30, 1917.

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

assumption that 1 second-foot develops 25 kilowatts. Low-water record at power 

plant not reliable; discharge computed from weir records obtained at sand box,, 

about one-fourth mile below intake.

EXTREMES OP DISCHARGE. Maximum mean daily discharge recorded, 1896-1917, 

was 90 second-feet in 1915 and 1917; no flow during periods in 1901 and 1912.

ACCURACY. Records good.

The diversion dam for this canal is on San Gabriel River in the SE. J SE. J sec. 31, 

T. 2 N., R. 9 W., about 5 miles above gaging station on San Gabriel River near Azusa, 

at the mouth of the canyon. The water is used for power development at a point 

about 1J miles north of Azusa. The water, after leaving the power plant, is divided 

for irrigation, a part being discharged into Azusa-Covina canal and the remainder into 

Duarte canal. During rainy season part of the water from the powel1 plant is wasted 

back into San Gabriel River below gaging station.

Los Angeles County. , RECORDS AVAILABLE. May 18,1916, to September 30, 1917..

GAGE. Vertical staff in weir box; read by L. E. Allon, canyon guard.

DISCHARGE. Determined by two rectangular weirs; left weir, 2.25 feet, right weir, 

2.26 feet long, having end contractions. Crest of left weir is at zero gage height; 

crest of right weir is two hundredths foot lower at one end. Rating table, computed from weir table, has been checked by current-meter measurements made 

at mouth of intake pipe in weir box.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 0.46 foot at 7 a. m. 

April 28 (discharge, 4.6 second-feet); minimum stage, 0.21 foot at 5 p. m. September 20-25 and 28-30 (discharge, 1.4 second-feet).

1916-17: Maximum stage recorded, 0.49 foot May 18-19, 1916 (discharge, 

5.0 second-feet); minimum stage, 0.21 foot September 20-25 and 28-30, 1917 

(discharge, 1.4 second-feet).

ACCURACY. Stagerdischarge relation considered permanent since amount of backwater for any stage is probably constant. Gage read to hundredths twice a day. 

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 oi this water is collected

LOCATION. In SW. \ 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. Not measured.

RECORDS AVAILABLE. December 3, 1916, to September 30, 1917 (discharge measurements only, April 14 to September 4, 1916).

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

bank at mouth of canyon, just above concrete control.

DISCHARGE MEASUREMENTS. Made by wading at various sections above gage.

CHANNEL AND CONTROL. Bed composed of sand, gravel, and bbulders; shifting. 

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

fills in above and below dam affecting stage-discharge relation. Left bank 

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

during high stages.

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

4.90 feet at 4 p. m. December 24 (discharge determined from extension of rating 

curve, 770 second-feet); stream dry at least part of the time during October and 

November.

DIVERSIONS. None above.

ACCURACY. Stage-discharge relation changed by deposits of gravel above and below 

concrete control. Rating curve fairly well defined. Operation of water-stage 

recorder satisfactory except as indicated in note to daily discharge table. Daily 

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

determined by inspecting recorder graph, except December 24, when hourly 

* discharge was averaged. Records good.

COOPERATION. San Dimas Water Co. furnished observer for water-stage recorder.

TTTJTTNGA CREE£ NEAR StTNLAND, CALIF.

LOCATION. About in 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. Not measured.

RECORDS AVAILABLE. October 28, 1916, to September 30, 1917 (discharge measurements only, April 1 to August 27, 1916).

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

wading at various sections near dam.

CHANNEL AND CONTROL. Bed composed of gravel and boulders; apparently permanent. Control is concrete dam which has a notch in center about 20 feet long 

and 1 foot deep with steel angle set in the notch near downstream face. Stage of 

zero flow, about gage height 0.45 foot.

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

3.35 feet at 4.30 p. m. December 24 (discharge, determined from extension of 

rating curve, 800 second-feet); minimum stage from water-stage recorder, 0.47 foot 

at 5 p. m. August 29 (discharge, 0.2 second-foot).

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

above station. There are two £mall diversions between gage and mouth of canyon.

REGULATION. None.

ACCURACY. Stage-discharge relation permanent. Frequent discharge measurements have been obtained and rating curve is well defined below 250 second-feet. 

Operation of water-stage recorder was generally satisfactory but gage-height recorc1 

was in error, December 2$ to February 5, as end of intake pipe was covered wit! 

gravel. Daily discharge ascertained by applying to the rating table mean daily 

gage height determined by inspecting recorder graph, except on December 

24-25, when hourly discharge was averaged. Records excellent except for 

December 28 to February 5, when discharge was estimated froto record of flow 

of Pacoima Creek and Arroyo Seco.

HAINES CREEK NEAR TtTJtTNGA, CALIF.

LOCATION. In NE. i NE. i sec. 18, T. 2 N., R. 13 W., about 800 feet above mouth of

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

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. February 7 to September 30, 1917. 

GAGE.- Gurley graph water-stage recorder with concrete well and house, on right

bank, just above concrete control, about 800 feet above mouth of canyon. 

DISCHARGE MEASUREMENTS. Made by volumetric method, when discharge was

very small, and on crest of dam. A bridge has been built 4 feet above dam for

use during high water.
SURFACE WATER SUPPLY, 1917, PART XI.

CHANNEL AND CONTROL. Bed composed of boulders and gravel overlying solid rock; 

permanent. Banks high and fairly clean. A concrete dam, having a maximum 

height of about 5 feet above bed rock, 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, 

making control more sensitive for low stages. Zero flow, gage height 0.23 foot.

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

0.60 foot at 4 a. m. February 22 (discharge, 0.48 second-foot); minimum stage 

from water-stage recorder, 0.32 foot September 20-30 (discharge, 0.03 second-foot).

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. This water is used 

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

station, develops 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 period, Daily discharge ascertained by applying to rating table mean daily gage height determined by inspecting recorder graph. Records excellent.

SURFACE WATER SUPPLY, 1917, PART XI. 73 

SANTA CLARA RIVER BASIN.

SESPE CREEK NEAR SESPE, CALIF.

/

LOCATION. At Bradfields camp, in Santa Barbara National Forestt, three-fourths 

of a mile below mouth of West Fork of Sespe Creek, 4$ miles above intake of 

Fillmore Canal, and about 6| miles northwest of Sespe, Ventura County.

DRAINAGE ABBA. 216 square miles (measured by Ralph Bennett, consulting engineer).

RECORDS AVAILABLE. October 1, 1915, to September 30, 1917 (not complete).

GAGE. Painted on large bouldefr and on rock cliff on left bank; read by G. H. 

Killgore.

DISCHARGE MEASUREMENTS. Made from cable 250 feet above gage or by wading.

CHANNEL AND CONTROL. Gravel and large boulders; fairly permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 12.0 feet February 

24 (discharge, 3,830 second-feet); minimum stage recorded, 4.33 feet on several 

days in September (discharge, 3.6 second-feet).

1915-1917: Maximum stage recorded, 18.7 feet January 17, 1916 (discharge, 

18,600 second-feet); minimum stage, 4.33 feet on several days in September, 

1917 (discharge, 3.6 second-feet).

ACCURACY. Stage-discharge relation fairly permanent. The high water on February 21 and 22, 1917, caused slight changes in the channel. Fairly well denned 

rating curves used October I to February 20; February 23 to March 13; and 

March 27 to September 30, 1917. Gage read to hundredths; number of readings 

a day not known. Daily Discharge ascertained by applying gage height as 

reported, to, rating table, except March 14-26 and September 30, when.it was 

interpolated. Records good.

COOPERATION. Gage-height record and nearly all discharge measurements furnished 

by Sespe Light & Power Co.

SANTA YNEZ RIVER BASIN. 

SANTA YNEZ RIVER NEAR SANTA BARBARA, CALIF.

LOCATION. About on line between sees. 10 and 11, T. 5 N., R. 27 W., at Gibraltar 

dam site, just above mouth of Devil Canyon Creek, and 7 miles north of Santa 

Barbara, Santa Barbara County. Mono Creek enters 3£ miles above station.

DRAINAGE AREA. 218 square miles at site 900 feet downstream from gage used since 

August 2, 1916 (measured on topographic maps).

RECORDS AVAILABLE. November 1, 1903, to April 30, 1907; October 1, 1907, to January 31, 1908; February 6, 1910, to September 30, 1917, Station was maintained 

about 4| miles above present site January 1 to June 20, 1903.

GAGE. Friez water-stage recorder installed August 2, 1916, on left bank at portal of 

tunnel 50 feet above base of Gibraltar dam. Previous gage was a staff in three 

sections about 900 feet below north portal of the Santa Barbara water-supply 

tunnel. April 13, 1911, gage datum was lowered 5.00 feet.

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

sections.

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

relatively permanent at low water. Control, which is base of Gibraltar dam, is 

satisfactory except for periods when flash boards and sand bags are placed on crest.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 8.8 feet at 5 p. m. 

December 24 (discharge, from extension of rating curve, -10,900 second-feet); 

minimum discharge, 0.2 second-foot September 15-30.

1904-1917: Maximum stage recorded, 23.0 feet at 8 p. m. January 25, 1914 (discharge, 13,100 second-feet); no flow during most of July to September 1904.

DIVERSIONS. City of Santa Barbara diverts water at gage for municipal use. The 

record includes this diversion. Practically all water in river was being diverted 

from July 14 to September 30.

REGULATION. None.

ACCURACY. Stage-discharge relation fairly permanent December 24 to May 29. 

During remainder of year flash boards and sand bags were in use on crest of dam 

and changes were frequently made. Two rating curves, fairly well defined to 

3,500 second-feet, were used December 24 to May 29; daily discharges for this period 

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

inspecting recorder graph. Discharge October 1 to December 23 estimated from 

discharge measurements and precipitation records; discharge May 30 to July 14 

interpolated between discharge measurements; July 15 to September 30, discharge from weir record of diversion, corrected for leakage. Records October 1 

to December 23, roughly approximate; remainder of record good.

COOPERATION. Gage-height record and most of discharge measurements furnished 

by city of Santa Barbara.

LOCATION . At highway bridge near east boundary of La Misidn Vieja de la Purfsima 

grant, 1J miles east of Lompoc, Santa Barbara County.

DRAINAGE AREA. 725 square miles (measured on topographic maps).

RECORDS AVAILABLE. November 10, 1906, to January 9, 1907; September 25,- 1907, 

to September 30, 1917 (except 1909).

GAGE. Vertical staff fastened to pier at right end of center span of bridge near downstream end; read by Donald McDonald. Datum lowered 1.00 foot June 27, 1917.

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

CHANNEL AND CONTROL. Sand; shifting. Banks high and not subject to overflow.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 3.20 feet at 

7.10 a. m., February 22 (discharge, 5,500 second-feet); minimum discharge, 18 

second-feet, September 25-30.

1906-1917: Maximum stage rec'orded, 13.0 feet, January 25, 1914 (discharge, 

41,800 second-feet); minimum discharge, 5 second-feet, October 13-21, 1913.

DIVERSIONS. Eicept for a small amount diverted by the city of Santa Barbara at 

Gibraltar dam, water is not diverted above the station, but there is some pumping 

from Wells along the banks of the river for irrigation.

REGULATION. None.

ACCURACY. Stage-discharge relation not permanent. Fairly well denned rating 

curves were used December 3-23, December 27 to January 30, January 31 to 

March 8, and March 17 to April 26. Gage read once a day to hundredths during 

low stages and to half-tenths at other times. Daily discharge ascertained by 

applying gage height to rating table for periods when tables were applicable; 

December 24-26 computed from a comparison with records'for Santa Barbara as 

gage heights do not appear to represent mean for these days. Remainder of 

record interpolated between discharge .measurements and by comparisons with 

Santa Barbara record. Records fair.

ALAMEDA CREEK NEAR NILES, CALIF.

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

above Nile?, one-fourth mile above highway bridge, and 1J miles northeast of 

Niles, Alameda County.

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

commission).
ALAMEDA CREEK BASIN. 93 ~

RECORDS AVAILABLE. October 1. 1916, to September 30, 1917.

GAGE. Water-stage recorder (Spring Valley Water Co. type) on right bank at highway 

water tank 1,800 feet above highway bridge.

DISCHARGE MEASUREMENTS. Made from suspension foot-bridge 800 feet below gage 

or by wading.

CHANNEL AND CONTROL. Bed composed of gravel; not permanent. Banks are high; 

channel straight from gage to some distance below suspension bridge. Lowwater control for gage solid rock and boulders.

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

10.45 feet at 5.30 a. m. February 25 (discharge, 10,160 second-feet); minimum discharge (stage not reported) 0.5 second-foot November 14-22.

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

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

near Sunolglen, p. 97.) Water for irrigation is diverted on right bank at Niles 

dam about a mile above station.

REGULATION. Spring Valley Water Co. has under construction a large storage reservoir 

on Calaveras Creek. June 20 to September 30 water was released from Calaveras 

reservoir.

ACCURACY. Stage-discharge relation not permanent. Frequent discharge measurements, covering entire range of stage, were obtained. Bating curves well defined. 

Daily discharge determined by averaging the results obtained by applying mean 

gage height for short period to rating table. Special care exercised in making discharge measurements, maintaining water-stage recorder and other equipment, and 

compiling record. Records excellent for station of this type.

COOPERATION. Data collected and compiled under presonal supervision of Paul 

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

California.

ALAMEDA CREEK NEAR DECOTO, CALIF.

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

Slough and about 1mile southwest of Decoto, Alameda County; about 6| miles 

below station in Niles Canyon near Niles. 

DRAINAGE AREA. Not measured.

RECORDS AVAEUABLE. October 1, 1916, to September 30, 1917.
ALAMEDA CREEK BASIN. 95

GAGE. Water-stage recorder (Spring Valley Water Co. type) on left bank, 400 feet 

above mouth of Dry Creek.

DISCHARGE MEASUREMENTS. Made from suspension footbridge just above gage or 

by wading. Measurements are also made at Rodriguez bridge, about 1£ miles 

downstream, and results reduced by discharge of Dry Creek to give flow at gages

CHANNEL AND CONTROL. Gravel, sand, and silt; not permanent. Banks are high 

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

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

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

about 19.0 feet, 9 p. m. February 21, discharge, 8,900 second-feet; stream dry 

October 1 to December 23, February 9-11,15-19, April 28 to July 16, and August 

7-17.

DIVERSIONS. See Alameda Creek near Niles, page 92. Water is also pumped from 

creek at four points above station for irrigation. At high stages water flows 

through Crandall Slough 1? miles above gage. Some water is returned to creek 

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

REGULATION. See Alameda Creek near Niles, page 92.

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

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

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

Records excellent for station of this type.

COOPERATION. Data collected and compiled under personal supervision of Paul 

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

California.

SURFACE WATER SUPPLY, 1917,, PART XI. 105

TULABE LAKE BASIN. 

TULARE LAKE IN KINGS COUNTY, CALIF.

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

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

5 miles southwest of Stratford.

DRAINAGE ABEA. Not measured. 

RECORDS AVAILABLE. March 15, 1906, to September 30, 1917 (incomplete). All 

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

GAGE. Vertical staff in three sections, two of which are fastened to the'headgate. 

High-water section is at junction of Smith's levee and the Empire levee two 

miles north. Gage read about once a week by Mrs. E. G. Kolbenstetter. Gage 

readings reduced to depth of water from the following data: Elevation of bottom 

of lake, 179.1 feet above mean sea level; elevation of zero of gage, 176.4 feet.

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

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

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

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

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

of the corner of sees. 27, 28, 33 and 34, T. 20 S., R. 20 E., about 10 miles south 

of Lemoore, near Stratford post office. The elevation of the zero of this gage 

was 171.0 feet. On August 20, 1913, a vertical staff in four sections was installed 

in main north and south waterway, 4 to 6 miles southeast of Stratford, its zero 

was also at elevation 171.0 feet. Sections No. 1 and No. 2 were 1 mile south of 

1910 gage in sec. 3, T. 21 S., R. 20 E. No. 3 was in sec. 10 and No. 4 was in 

sec. 15, 1 and 2 miles, respectively, south of sections Nos. 1 and 2.

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

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

was used up to October 28, 1916. The present high-water section was installed 

October 28, 1916.

EXTREMES OP STAGE. Maximum depth recorded during year, 9.1 feet February 18; 

minimum depth recorded, 6.6 feet September 22 and 30.

1906-1917: Maximum depth, 14.0 feet June 21, 1907; the lake was empty a 

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

and last part of November, 1915.

"The lake is roughly rectangular and its greatest length is from northwest to southeast. In November, 1907, when its margin was carefully determined, the lake had 

an area of about 274 square miles, a maximum depth of 12.4 feet, an average length 

of 20 miles, and a width of 13.5 miles; the water's edge was 3 miles from the town of 

Corcoran and the water surface about 12 feet below.

The lake bed resembles a flat saucer. The flat, level area in the bottom is approximately 180 feet above mean sea level and covers about 55 square miles. The lowest 

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

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

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

KAWEAH RIVER NEAR THREE RIVERS, CALIF.

LOCATION. In SE. | sec. 27, T. 17 S., R. 28 E., at J. 0. Carter's ranch, 1£ miles southwest of Three Rivers, Tulare County. South Fork enters three-fourths mile and 

North Fork 3 miles above station.

DRAINAGE AREA. 520 square miles.

RECORDS AVAILABLE. April 29, 1903, to September 30, 1917.

GAGE. United States Weather Bureau gage in three sections on left bank a few feet 

above cable and one-fourth mile back of observer's house; read by J. 0. Carter. 

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. For about two years the two gages were read interchangeably, according 

to varying conditions of repair of-each. On October 19, 1914, the Geological Survey repaired the upper section of the Weather Bureau gage and has used this gage 

since.

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

CHANNEL AND CONTROL. Gravel and boulders; fairly permanent.

EXTREMES OP DISCHARGE. Maximum stage recorded "during year, 10.0 feet, determined from flood marks, night of February 21 (discharge, from extension of rating 

curve, about 6,270 second-feet); minimum stage recorded, 4.75 feet at 6 p. m. 

September 29 (discharge, 46 second-feet).

1903-1917: Maximum stage recorded, 13.5 feet at 11 a. m. January 17, 1916 

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

stage recorded, 4.35 feet August 22, 1914 (discharge, 30 second-feet).

DIVERSIONS. Several small ditches divert water for local irrigation and domestic use 

above the station.

REGULATION. Power is developed on the Middle and East forks but effect of regulation is thought to be small.

ACCURACY. Rating curve well denned between 40 and 4,000 second-feet; above 4,000 

second-feet it is an extension. Gage read to hundredths twice daily. Daily discharge ascertained by applying mean daily gage height to rating table. Records 

excellent except those for extremely high stages which are probably good.

ACCURACY. Stage-discharge relation for low water changed October 4, January 4 

and February 26; rating curves before and after changes fairly well defined and 

merge into one at stage of 10 feet, Gage read to quarter-tenths once daily. Daily 

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

DISCHARGE MEASUREMENTS. Made from cable half a mile above gage or by wading. 

CHANNEL AND CONTROL. Bed composed of boulders and bedrock. Control is a compound weir consisting of a 64-foot rectangular sharp-crested weir with end contractions practically suppressed and an 8-foot rectangular sharp-crested weir 1 foot

deep in middle for low flow. Weir is very satisfactorily installed and leakage is

very small. 

ICE. Considerable ice forms at the station but it is unlikely that stage-discharge

relation is ever affected by it. 

DIVERSIONS. Fresno Flume & Lumber Co.'s two flumes divert water at Shaver Lake

dam. This water is used for transporting lumber and is not returned to stream

but conveyed to do vis and there used for irrigation. 

REGULATION. During dry season entire flow is regulated at Shaver Lake dam. Capacity of Shaver Lake reservoir is 4,880 acre-feet (reported by I. B. Bennett). 

ACCURACY. Stage-discharge relation permanent. Rating curve well denned below

800 second-feet and extended above. Daily discharge ascertained with a discharge integrator. Records excellent. 

COOPERATION. Stage record furnished by Fresno Flume & Lumber Co., through I. B.

Bennett, president.

FRESNO FLUME & LUMBER CO.'S UPPER FLUME AT SHAVER, tiALIF. 

\

LOCATION. About 75 feet below intake at Shaver Lake dam at Shaver, Fresno County. 

RECORDS AVAILABLE. November 13, 1915, to September 30, 1917. 

GAGE. Lietz water-stage recorder with its zero set at same elevation as crest of weir. 

DISCHARGE MEASUREMENTS. The weir was rated by discharge measurements made

from foot plank a short distance below. 

CHANNEL AND CONTROL. Channel is rectangular timber flume; control is 2J-foot

rectangular weir with steel crest. 

ICE. Considerable ice and snow accumulate in flume during winter. Flume not in

use during this period.
124r SURFACE WATER SUPPLY, 1917, PART XI.

AcctrRACY. Stage-discharge relation changed, probably after December 30. Two 

well-defined rating curves were used October 1 to December 30 and May 18 to 

September 30. Mean daily gage height obtained by inspecting recorder graph. 

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

hourly discharge averaged for days when there was much change in stage and 

when flume was dry for part of the day. Records good.

COOPERATION. Stage record furnished by Fresno Flume & Lumber Co.

The flume is used for transporting lumber about the yard at mill. The water is then 

wasted into lower flume. There is a slight leakage in flume which is returned to 

Stevenson Creek above gaging station at Shaver.

FRESNO FLUME & LUMBER CO.'S LOWER FLUME AT SHAVER, CALIF.

LOCATION. About 75 feet below intake at Sharver Lake dam at Shaver, Fresno County.

RECORDS AVAILABLE. January 6, 1916, to September 30, 1917.

GAGE. Lietz water-stage recorder; zero at elevation of crest of weir.

DISCHARGE MEASUREMENTS. The weir was rated by discharge measurements made 

from foot plank a short distance below.

CHANNEL AND CONTROL. Channel is rectangular timber flume; control is an 8-foot 

rectangular weir with steel crest.

ICE. Considerable ice and snow accumulate in flume during the winter when water 

is not running.

ACCURACY. Stage-discharge relation changed, probably after December 30, when 

flume was not in use. Two well-defined rating curves were used, one applicable 

October 1 to December 30, the other February 9 to September 30. Daily discharge ascertained by applying to rating table mean daily gage height obtained 

by inspecting recorder graph; hourly discharge averaged for days when there 

was much change in stage. Records good.

COOPERATION. Record of stage furnished by Fresno Flume & Lumber Co.

The water is used for transporting lumber from mill to Clovis, and is then used for 

irrigation.

SAN JOAQUIN RIVER BASIN. 127

FBESNO RIVEB BASIN. /* ' 

FRESNO RIVER NEAH KNOWLES, CALIF.

LOCATION. In N. \ sec. 15, T. 8 S., R. 20 E., at Fresno Crossing, about 6 miles northeast of Rnowles, Madera County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. September 16, 1911, to January 1, 1914; November 13, 1915, 

to September 30, 1917.

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

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

Gage read by J. E. Gayman. There have been several changes in gage sections; 

original datum has probably been maintained.

DISCHARGE MEASUREMENTS. Made from cable about 300 feet below bridge or by 

wading.

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

outcroppings of bedrock; fairly permanent. A concrete control was installed 

November 4, 1916.

EXTREMES OP DISCHARGE. Maximum stage recorded, during year,^6.0 feet at 5 p. m. 

February 21 (discharge, determined from extension of rating curve, 4,500 secondfeet); miniTniiTn stage recorded, 0.64 foot at 7 a. m. September 7 (discharge, 3.8 

second-feet).

1911-1914 and 1916-1917: Maximum stage recorded, February 21,1917; minimum stage recorded, 0.20 foot, August 6-10, 1913 (discharge, 1 second-foot).

DIVERSIONS. Water is diverted above the station for irrigation and lumbering PUTREGULATIONS. Diurnal fluctuation at low stages due to diversions above.

ACCURACY. Stage-discharge relation was changed by construction of a concrete 

control on November 4. Rating curve before change well denned between 25 

and 600 second-feet and extended above; curve after change well denned 

between 5 and 400 second-feet and extended above; curves coincide above 1,450 

second-feet. Gage read to quarter-tenths once or twice daily. Daily discharge 

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

for medium and probably fair for low and extreme high stages.

Discharge measurements of Fresno River near Knowles, Calif., during the year ending

Sept. 30, 1917.

LOCATION. In SW. i SE. i sec. 17, T. 1 N., R. 20 E., in Yosemite National Park 

about three-fourths mile below Hetch Hetchy dam site and 11 miles northeast of 

Sequoia, Tuolumne County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. December 20, 1914, to September 30, 1917. This station was 

established to take the place of the station at the dam site when it became necessary to discontinue that station on account of construction.

GAGE. Gurley weight-driven printing water-stage recorder on left bank. Difference 

in elevation between the zero of this gage and that of gage at dam site, 53.15 feet.

DISCHARGE MEASUREMENTS. Made from cable 30 feet below gage, or by wading.

CHANNEL AND CONTROL. Boulders and solid rock; considered permanent. Bed at 

measuring section was smoothed off by removing some boulders. Banks high 

and not subject to overflow.

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

13.8 feet at 4 a. m. June 10 (discharge, 10,000 second-feet); minimum stage, from 

water-stage recorder, 1.56 feet, September 30 (discharge, 34 second-feet). See 

foot-note to daily-discharge table.

1915-1917: Maximum stage, recorded June 10, 1917; minimum stage, from 

water-stage recorder, 1.16 feet November 4 to 7, 1915 (discharge, 14 second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS . None.

REGULATION. None.

ACCURACY. Stage-discharge relation changed December 4 and June 9 by debris 

lodging upon control. Rating burves well defined. Daily discharge ascertained 

by applying to rating table mlean daily gage height determined by averaging 

gage-height record or, for days of considerable fluctuation, by averaging mean 

hourly discharge (see footnote to daily-discharge table). Records excellent.

TTTOLUMliTE RIVER NEAR BUCK MEADOWS.i CALIF.

LOCATION. In SW. £ sec. 24, T. 1 S., R. 17 E., 1 mile below junction with South. Fork 

of Tuolumne River and 2 miles north of Buck Meadows, Mariposa County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. September 2, 1907, to September 30, 1917 (not complete).

GAGE. Gurley electric printing water-stage recorder on left bank, put in operation 

January 2, 1913. Previously, station was maintained by the Yosemite Power Co. 

in the pool above. Gage consisted of a vertical staff on left bank at site of United 

States Geological Survey's present cable. The Survey began reading the gage 

November 17, 1913, and developed a curve of relation.

DISCHARGE MEASUREMENTS. Made from cable one-third mile above gage.

CHANNEL AND CONTROL. Boulders and solid rock; probably permanent. Banks 

high and not subject to overflow.

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

11.3 feet at 2 a. m. June 9 (discharge, 17,700 second-feet); minimum stage from 

water-stage recorder, 0.76 foot at 11 p. m. September 30 (discharge, 50 second-feet). 

1907-1917: Maximum stage recorded, 14.00 feet January 14, 1909 (discharge, 

27,200 second-feet); minimum stage recorded, 0.70 foot October 3,1912 (discharge, 

32 second-feet).

DIVERSIONS. A small amount of water is diverted from South Fork of Tuolumne 

River, at Harden ranch, 7 miles above its mouth for irrigation in the vicinity of 

Groveland.

REGULATION. None.

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

trouble with water-stage recorder caused breaks in record (see footnote to dailydischarge table). Mean daily gage height determined by averaging gage heights 

recorded every 15 minutes by the water-stage recorder. Daily discharge ascertained by applying mean daily gage height to rating table except for periods of 

missing record, for which it was. estimated. Records excellent when recorder is 

running; estimates considered fair.

TTTOLTTMNE RIVER NEAR LA GRANGE, CALIF.

LOCATION. In NE. £ SE. i sec. 17, T. 3 S., R. 14 E., at La Grange dam, 1£ miles 

northeast of La Grange, Stanislaus County.

DRAINAGE AREA. 1,500 square miles.

RECORDS AVAILABLE.---August 30, 1895, to September 30, 1917.

GAGE. Painted on rock ledge on right bank 80 feet above dam; read by F. A. Townsend. Zero of gage is at average elevation of crest of dam. Until March 31,1908, 

the station was located at the wagon bridge at La Grange.
SAN JOAQUIN EIVEE BASIN. 147

DISCHARGE. Computed by means of weir formula from gage heights showing depth 

of water on crest of curved masonry diversion dam. Coefficient was determined 

from current-meter measurements made at highway bridge at La Grange; corrected 

to give discharge at dam. To obtain the total flow of Tuolumne River above 

La Grange dam, it is necessary to combine the flow over the dam with the discharge of Modesto, Turlock, and Yosemite Power Co.'s canals.

CHANNEL AND CONTROL. Bed composed of gravel and boulders. Dam is a permanent control.

EXTREMES OF DISCHARGE. Maximum stage during year, 6.5 feet June 9 (discharge, 

15,000 second-feet); minimum stage, no flow over dam (see footnote to dailydischarge table).

1907-1917: Maximum stage recorded, 16.45 feet, on the morning of January 

31, 1911; crest of flood from high-water mark on gage (discharge, 60,300 secondfeet); minimum stage, no flow over dam for long periods every year.

DIVERSIONS. Modesto and Turlock canals divert at dam. Yosemite Power Co. 's canal 

heads 13 miles above the dam and returns its water below the dam, about half a. 

mile above the bridge at La Grange. There is also a diversion from South Fork 

of Tuolumne River at Harden ranch for use in vicinity of Groveland.

REGULATION. At low water the small amount of storage behind La Grange dam 

affects the flow.

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

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

mean daily gage height to rating table.. Records good. The flow over the dam 

is at times affected by seepage through dam and by the water discharged 

through the ports and sand gates in the dam.

No discharge measurements were made at this station during the year.

Daily discharge, in second-feet, of Tuolumne River near La Grange, Calif., for the year

ending Sept. SO, 1917.

150 SURFACE WATEB SUPPLY, 1917, PART XI.

CHERRY CREEK NEAR SEQUOIA, CALIF.

LOCATION. In SW. J sec. 28, T. 2 N., R. 19 E., in Stanislaus National Forest, at abandoned sawmill camp 3 miles by trail from Lake Eleanor and about 13 miles north 

of Sequoia, Tuolumne County.

DRAINAGE AREA. 114 square miles 1 (above dam site in sec. 5, T. 1 N., R. 19 E.).

RECORDS AVAILABLE. April 1, 1910, to September 30, 1917.

GAGE. Gurley printing water-stage recorder on right bank 800 feet above site of old 

suspension bridge. Original gage was a Lietz graph water-stage recorder at the 

bridge. It was moved upstream to present site (new datum) October 22, 1913, 

and replaced by the present gage (same datum) November 30,1914.

DISCHARGE MEASUREMENTS. Made from cable 800 feet below gage or by wading.

CHANNEL AND CONTROL. Bed is fine gravel and sand, which shifts slightly, but 

control is a solid-rock dike except at right bank, where it is gravel and small 

boulders. Zero flow is at gage height 0.4 foot. Channel is straight above and 

curved to right below. Left bank is high; right bank fairly high and probably 

not .subject to overflow.

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

9.1 feet at 10 p. m. June 9 (discharge, determined from extension of rating curve, 

3,800 second-feet); minimum stage from water-stage recorder,0.81 foot, September 

30 (discharge, 1.0 second-foot).

1910-1917: Maximum mean daily discharge, 7,000 second-feet January 30, 1911 

(maximum stage unknown); channel dry September 6-12,1910.

ICE. Stream freezes over at gage but not at control. No ice effect on stage-discharge 

relation has been detected.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation for high water changed sometime before high 

water by two fallen trees in the stream below control. Rating curve well 

denned between 10 and 3,000 second-feet. Operation of water-stage recorder 

satisfactory throughout the year except those periods stated in footnote to dailydischarge table. Daily discharge ascertained by applying to rating table mean 

daily gage height determined by averaging the readings for the day. Records 

excellent, except those for extreme low water, which are considered good.

LOCATION. In SW. i sec. 3, T. 1 N., R. 19 E., in Yosemite National Park, one-third 

mile below Lake Eleanor dam site, 1J miles below Lake Eleanor, and 11 miles 

north of Sequoia, Tuolumne County.

DRAINAGE APEA. 79 square miles l (above dam site in sec. 3, T. 1 N., R. 19 E.).

RECORDS AVAILABLE. November 20, 1909, to September 30, 1917.

GAGE. Lietz water-stage recorder in wooden house on reinforced concrete well on 

right bank. Previous to November 13, 1915, recorder was 1 mile upstream 

on right bank. Short distance upstream from that location was a vertical staff 

in two sections which was probably the original gage.

DISCHARGE MEASUREMENTS. Made from cable 75 feet above gage or by wading.

CHANNEL AND CONTROL. Channel of small boulders; control of large boulders, 

ledge, and concrete wall for low water. Zero flow is at stage 0.9 foot. Channel 

straight above and below. Banks not subject to overflow.

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

6.25 feet at 5 a. m. June 10 (discharge, 1,580 second-feet); minimum stage from

water-stage recorder, 1.11 feet September 29 and 30 (discharge, 0.5 second-foot).

1910-1917: Maximum stage recorded, 13.1 feet January 30, 1911 (discharge,

5,000 second-feet); channel dry September 8 to 14, 1910.

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. None.

REGULATION. None.

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

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

by inspecting recorder graph. Records excellent.

154 SURFACE WATER SUPPLY, 1917, PART XI.

EVAPORATION FROM LAKE ELEANOR NEAR SEQUOIA, CALIF.

LOCATION. In sec. 35, T. 2 N., R. 19 E., in Yosemite National Park, about 12 miles 

north of Sequoia, Tuolumne County.

RECORDS AVAILABLE. February 27, 1915, to September 30, 1917.

EQUIPMENT. Evaporation pan is 48 inches in diameter, 10 inches deep, hung by 

four turnbuckles in a raft of cedar logs. Raft is anchored about 1,000 feet from 

the nearest shore.

METHOD. Observations are made several times a week by measuring the amount of 

water added to or taken from the pan in order to bring the water surface in the 

pan to the point of a metal cone set at its center. The water added or taken 

out is measured in a small can, the cubical content of which is known. Number 

of cans is reduced to depth in inches and that, corrected by the amount of precipitation, gives amount of evaporation.

ELEVATION. About 4,700 feet above sea level.

Total evaporation in inches, since last day recorded, of Lake Eleanor near Sequoia, Calif., 

for the year ending Sept. 30, 1917.

just above waste gate, three-fourths mile above power house, 1J miles northeast 

of La Grange, Stanislaus County, and 13| miles below intake on Tuolumne River. 

Canal is on left bank of river.

RECORDS AVAILABLE. 1908 to September 30, 1917 (not complete).

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

Sackett.

DISCHARGE MEASUREMENTS. Made in flume just below gage.

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

EXTREMES OF DISCHARGE. Maximum discharge recorded 1910-1917, 68 second-feet 

most of summer of 1916 and early part of 1917; no flow during parts of every year.

ACCURACY. Stage-discharge relation changed by silting up of canal in February. 

Rating curve before and after change fairly 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.

Yosemite Power Co.'s canal takes water from the south side of Tuolumne River 

at Indian Bar, in the SW. £ sec. 6, T, 2 S., R. 15 E., about 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 lecally known as the "La Grange 

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

hydroelectric plant which was installed late in 1907. The power house is on the left 

bank of the river about half a mile above the town of La Grange and is below the 

dam and head works of the Turlock and Modesto irrigation canals. Water diverted 

by canal is returned to river at power house. 

The following discharge measurement was made by Charles Leidl: 

March 25, 1917: Gage height, 2.76 feet; discharge, 62 second-feet.

and the cross section increased. The discharge per foot stage above 1.5 feet has

been increased. 

CAPACITY. Maximum discharge 1903-1917, 954 second-feet part of summer of 1917;

stage, 5.2 feet 

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

defined. Gage read to hundredths twice daily and manipulation of gates noted.

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

or by averaging results obtained by applying gage heights for parts of day to

rating table. Records excellent. 

COOPERATION. Gage-height record and some discharge measurements furnished by

Modesto Irrigation District.

166 SURFACE WATER SUPPLY, 1917, PART XI.

STANISLAUS RIVER NEAR KNIGHTS FERRY, CALIF.

LOCATION. In SW. i sec. 1, T. 1 S., R. 12 E., 300 feet above old Tulloch dam, 2 miles 

above Goodwin dam and 6 miles above Knights Ferry, Stanislaus County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. December 18, 1915, to September 30, 1917.

GAGE. Stevens continuous water-stage recorder on right bank in reinforced concrete 

well and house. Previous to July 28,1917, record is from a Gurley electric printing water-stage recorder.

DISCHARGE MEASUREMENTS. Made from cable 20 feet upstream from gage or by 

wading.

CHANNEL AND CONTROL. Bed composed of solid rock and shifting sand; straight for 

250 feet above and 300 feet below; one channel at all stages. Control is Tulloch 

dam. Point of zero flow, gage height 0.9 foot.

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

9.11 feet at 3.45 a. m. February 21 (discharge, determined from extension of rating 

curve, 17,400 second-feet); minimum stage from water-stage recorder, 1.33 feet 

8 to 10 p. m. November 10 (discharge, 213 second-feet).

1916-1917: Maximum stage recorded February 21, 1917; minimum stage recorded, 1.21 feet at 3 a. m. September 8 and 16 and 6 a. m. September 10, 1916 

(discharge, 146 second-feet).

DIVERSIONS. Ditches diverting water for hydraulic mining are numerous 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). The water diverted for power development 

on Middle Fork at Sand Bar Flat near Avery is returned to river above this station.

REGULATION. Storage is developed in Middle Fork (see Relief Creek near Baker 

Station), North Fork, and" South Fork drainage basins.

ACCURACY. Stage-discharge relation permanent. Rating curve well denned below 

10,000 second-feet and extended above. Recorder not running during periods 

stated in footnote to daily discharge table. Mean daily gage height ascertained 

by averaging readings printed every fifteen minutes by the printing water-stage 

recorder and by an approximate method of integrating the graph made by the 

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

daily gage height to rating table. Records excellent for periods for which 

recorder graph was obtained.

TTTICA GOLD MUTING CO.'S CANAL NEAR AVERY, CALIF.

LOCATION. In sec. 35, T. 5 N., R. 15 E., about 450 feet below headworks on North 

Fork of Stanislaus River and 5 miles northeast of Avery, Calaveras County.

RECORDS AVAILABLE. July 14, 1914, to September 30, 1917.

GAGE. Enameled vertical staff gage, installed May 19, 1915, on right side of flume; 

read by James Hunter. Previous to May 19, 1915, a vertical staff gage was 

located 300 feet above and on the right bank. It was too near the headgate and 

could not be properly rated.

DISCHARGE MEASUREMENTS. Made from footplank across flume at gage.
172 SURFACE WATEE SUPPLY, 1917, PART XI.

CHANNEL AND CONTROL. Rectangular wooden flume.

EXTREM-ES OF DISCHARGE. Maximum stage recorded, 1.65 feet May 19, 1915 (discharge, 116 second-feet).

ICE. Stage-discharge relation may be affected by ice.

ACCURACY. Stage-discharge relation changed; not affected by ice during year. 

Rating curve well defined. Gage read to half-tenths once a day except January 

to September, when it was read on alternate days. Daily discharge ascertained 

by applying daily gage height to rating table. Discharge for days on which 

gage was not read estimated the same as on previous day up to July 12 and 

interpolated after that date. Records good.

COOPERATION, Gage-height record furnished by Utica Gold Mining Co.

SOUTH FORK OF STANISLAUS RIVER AT STRAWBERRY,! CALIF.

LOCATION. In SE. J sec. 17, T. 4 N., R. 18 E., at site of former Sonora-Bridgeport 

State highway bridge at Strawberry, Tuolumne County, a summer resort in 

Stanislaus National Forest, 1£ miles below mouth of Herring Creek and 15 miles 

northeast of Confidence.

DRAINAGE AREA. About 54 square miles.

RECORDS AVAILABLE. October 20, 1911, to January 31, 1917, when station was 

discontinued.

GAGE. Vertical staff on left bank fastened to abutment of former bridge about 30 

feet above suspension footbridge. Gage read by an employee of Sierra & 

San Francisco Power Co. Original gage, which was at the same place, was torn 

out when the bridge was removed August 31,1914. A temporary gage was used 

until October 10 and the old gage was reinstalled October 14. Original datum has 

probably not been maintained.

DISCHARGE MEASUREMENTS. Made from suspension footbridge, or by wading.

CHANNEL AND CONTROL. Gravel and boulders; appear permanent. Left bank is 

about 20 feet high; right bank is lower but probably is not subject to overflow.

EXTREMES OF DISCHARGE. 1911-1917: Maximum stage recorded, 5.4 feet at 4 p. m. 

June 8, 1915 (discharge, 1,450 second-feet); minimum stage recorded, 1.15 feet 

November 2 and 3, 1912 (discharge, 3 second-feet).

ICE. Stage-discharge relation is probably slightly affected by ice.

DIVERSIONS. None above. 

REGULATION. The flow is partly regulated by three reservoirs which have been 

constructed above the station to supply Tuolumne and Sonora with water for 

domestic use. This water is diverted about 10 miles below the station.

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

well defined below 900 second-feet. Gage read to half-tenths twice daily. Daily 

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

Records good.

COOPERATION. Gage-height record furnished by Sierra & San Francisco Power Co., 

through H. F. Jackson, general manager.

COSUMNES RIVER AT MICHIGAN BAR, CALIF.

LOCATION. In NW. £ SE. £ sec. 36, TVS N., R. 8 E., at highway bridge at Michigan 

Bar, Sacramento County, 5^ miles southwest of Latrobe. North and Middle forks 

unite 12 miles above station.

DRAINAGE AREA. 524 square miles.

RECORDS AVAILABLE. October 20,1907, to SeptemberUO, 1917.

GAGE. Vertical staff on downstream end of bridge pier, near left bank; read by 

C. B. Ruman.

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

CHANNEL AND CONTROL. Sand, gravel, and small boulders; fairly permanent. 

Stage of zero flow, gage height, 1.4 feet±0.1 foot.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 11.0 feet at midnight February 21 (discharge, 22;900 second-feet); minimum stage recorded, 2.00 

feet August 24 to September 25 (discharge, 6.0 second-feet).

1907-1917: Maximum stage recorded, 11.0 feet February 21, 1917 (discharge, 

22,400 second-feet); minimum stage, river dry July 25 to September 16, 1908.

DIVERSIONS. Douglas and Enterprise ditches, which have a combined capacity of 

about 50 second-feet, divert from the Middle and South forks. The water is used 

for power, domestic, and irrigation supplies at Plymouth and vicinity. Slug 

Gulch ditch capacity of 7 or 8 second-feet also diverts water from the Middle 

fork when prior appropriations permit. Michigan Bar canal, which has a capacity 

of about 50 second-feet, heads on the main Cosumnes at Musicdale Creek. No 

record is available showing the amount of water that is diverted.

REGULATION. Flow is partly regulated by diversions.

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

6 second-feet. Gage reacl to hundredths twice daily. Daily discharge ascertained 

by applying mean daily gage height to rating table. Records excellent except 

those for low water, which are good.

DREWS CREEK NEAR LAKEVTEW, OREG.

LOCATION. In SW. \ sec. 4, T. 40 S., R. 18 E., at highway bridge half a mile below 

mouth of Willow Creek, 1 mile below Drews Creek dam, and 18 miles southwest 

of Lakeview, Lake County.

DRAINAGE AREA. 211 square miles.

RECORDS AVAILABLE. January 16,1909, to September 30, 1917, when station was 

discontinued,

GAGE. Friez water-stage recorder since March 19, 1912, referred to a vertical staff 

on the highway bridge, installed March 1, 1910. Gage inspected by R. J. Gilbert 

and James McShane. Inclined staff at station No. 1, at the dam site a mile above 

present gage, used January 16 to May 31, 1909, and vertical staff at station No. 2, 

at a dump-car bridge 100 feet below the dam site, November 20,1909, to February 

28, 1910.

DISCHARGE MEASUREMENTS. Made from wagon bridge or by wading.

CHANNEL AND CONTROL. Bed composed oi gravel and sand; shifts slightly; drift 

and growth of aquatic plants may collect on control occasionally and affect 

stage-discharge relation. At highest stages water flows into a second channel.

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

5.82 feet at 3 p. m. April 23 (discharge, 828 second-feet); minimum stage, from 

water-stage recorder, 1.77 feet at 8 a. m. December 5 (discharge uncertain; 

probably less than 1 second-foot).

1909-1917: Maximum stage recorded, 8.3 feet January 16, 1909, on original 

gage, (discharge, 2,730 second-feet). Gage height estimated as 12 to 13 feet on 

gage No. 2 (gage washed out) on evenings of March 1 and 2, 1910 (discharge 

probably about 3,000 second-feet. Creek dry at times prior to construction of 

reservoir.

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

for one to two months.

DIVERSIONS. The North Drews canal of the Goose Lake Valley Irrigation Co. diverts 

water past the station; record is kept of its discharge and this is added to determine 

the total run-off from the creek.
GOOSE LAKE BASIN". 191

REGULATION. Since the last part of 1912 water has been stored in the reservoir 

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

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

corrected for storage are often negative during the summer as the discharge into 

the reservoir becomes too small to offset the evaporation losses.

ACCURACY. Stage-discharge relation fairly permanent and rating curve fairly well 

defined for period February 22 to July 8, which includes practically all the runoff; unstable rest of year on account of ice and growth of aquatic plants. Operation of water-stage recorder satisfactory^for most of year. Daily discharge ascertained by applying to the rating table mean daily gage height determined by 

inspecting recorder graph, or for days of considerable fluctuation, by averaging 

results obtained by applying to the table the gage height for various subdivisions 

of the day. Discharge July 9 to September 30 computed by shifting-control 

method. Records good'March to June; fair, July to September; roughly approximate, October to February.

NORTH DREWS CANAL NEAR LAKEVIEW, OREG.

LOCATION. In sec. 3, T. 40 S., R. 18 E., nearly opposite station on Drews Creek, 

about 2 miles below intake of canal at Drews Creek dam, one-third mile above 

a spillway, 18 miles southwest of Lakeview, Lake County.

RECORDS AVAILABLE. March 18, 1914, to September 30, 1917, when station waa 

discontinued.

GAOE. Vertical staff on right side of flume at station 107. A gage just below outlet 

gate of dam was also read during 1915. Gage readers, R. J. Gilbert and James 

McShane.

DISCHARGE MEASUREMENTS. Made from collar of flume or by wading.

CHANNEL AND CONTROL. 12-foot wooden flume.

EXTREMES OP DISCHARGE. Maximum stage recorded during year and during period 

1914 to 1917, 2.50 feet July 17-21 (discharge, 112 second-feet). Canal dry at 

times.

ACCURACY. Stage-discharge relation not permanent owing to growth of aquatic 

plants. Rating curve used April 22 to July 31, fairly well denned. Daily discharge ascertained by applying daily gage height to rating table and interpolating records for days for which gage was not read. Shifting-control method 

used for October 1 to November 6, and August 1 to September 30; changes in 

stage-discharge relation somewhat uncertain; records only fair. Gage read to 

half-tenths daily July 8 to September 30, and about three times a week prior to 

June 9.

North Drews canal diverts water from drews Creek at reservoir dam in the SE. J

COTTONWOOD CHEEK NEAR LAKEVIEW, OREG.

LOCATION. In SW. | sec. 29, T. 38 S., R. 19 E., about half a mile below dam site of 

a proposed storage reservoir, near edge of valley, and 10 miles northwest of Lakeview, Lake County.

DRAINAGE AREA. 30 square miles.

RECORDS AVAILABLE. November 22, 1908, to September 30, 1&17, when station was 

discontinued.

GAGE . Vertical staff on left bank; read once daily by Peter Segner. From November 

22,1908, to January 18, 1909, a gage just above a weir, one-fourth mile below the 

dam site, was used.

103503° 20 WSP 461 18
194 SURFACE WATER SUPPLY, 1917, PAET XI.

DISCHARGE MEASUREMENTS. Made from a footbridge 40 feet below present gage, or 

by wading near gage.

CHANNEL AND CONTROL. Bed composed of clean gravel; somewhat shifting.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 3.0 feet May 10 

(discharge, 265 second-feet); minimum stage recorded, 0.20 foot in October and 

November (discharge, 2 second-feet).

1908-1917: Maximum stage recorded, 3.4 feet November 23, 1909 (discharge, 

337 second-feet); minimum discharge, 1 second-foot in 1909, 1910, 1913, and 1914.

ICE. Stage-discharge relation seriously affected by ice from November to March; flow 

estimated.

DIVERSIONS. At present practically no diversions above station.

ACCURACY. Stage-discharge relation for stages below 0.7 foot changed during high 

water of April and May; affected by ice November 13 to March 28. Two welldefined rating curves used. Gage read to half-tenths once daily. Daily discharge ascertained by applying daily gage height to rating table. Records fair 

for May and April on account of diurnal fluctuation; poor November to February 

owing to lack of measurements to determine effect of ice obstruction; good for 

rest of year.

SACRAMENTO RIVER BASIN. 

SACRAMENTO RIVER NEAR RED BLUFF, CALIF.

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

below proposed Iron Canyon dam site and 4 miles northeast of Red Bluff, Tehama 

County. Paines Creek enters about 3 miles above and Antelope Creek 7 miles 

below station.

DRAINAGE AREA. 9,300 square miles, not including the 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 the drainage area including Goose Lake, should be 

used with caution because of the large noncontributing area.

RECORDS AVAILABLE. January 28, 1902, to September 30, 1917. In 1879 the State 

engineer and in 1893 and 1894 the commissioner of public works made measurements at this point. From April 30, 1895, to June 30, 1902, a gaging station was 

maintained at Jellys Ferry, 12 miles above Red Bluff.

GAGE. Staff in seven sections on left bank; read by Richard Groebe. Several gages 

have been used at this station, but all observations have been reduced to the 

present datum. The United States Weather Bureau gage at Red Bluff has been 

used occasionally.

DISCHARGE MEASUREMENTS. Made from cable 50 feet above the gage.

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

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 28.0 feet at 4.20 

p. m. February 11 (discharge, 188,000 second-feet); minimum stage recorded, 1.0 

foot August 14-16 and September 6-9, 19-20 (discharge, 4,200 second-feet).

1902-1917: Maximum stage recorded, 35.2 feet, February 3, 1909 (discharge, 

278,000 second-feet); minimum stage recorded, 0.9 foot September 7-28, 1903 

(discharge, 3,980 second-feet).

DIVERSIONS. A small amount of water is diverted from some of the minor tributaries 

for irrigation.

REGULATION. No large storage reservoirs have been developed in the drainage 

area above the station.

ACCURACY. Stage-discharge relation permanent except for slight variation at low 

water, the maximum amount of which is 5 per cent at the minimum recorded 

stage of 0.9 foot. Such a change probably occurred February 25. Rating curves 

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

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

SACRAMENTO RIVER BASIN. 211 

FEATHER RIVER AT OROVILLE, CALIF.

LOCATION. In serf. 8, T. 19 N., R. 4 E., at highway bridge at Oroville, Butte County, 

6 miles below junction of North and Middle forks and 30 miles above mouth of 

Yuba River.

DRAINAGE AREA. 3,640 square miles.

RECORDS AVAILABLE. January 1,1902, to September 30,1917.

GAGE. Friez water-stage recorder 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 

with 2 feet added to the readings to reference them to the datum of the United 

States Geological Survey staff gage installed on left bank about 1,000 feet above 

the bridge in December, 1905. The latter gage was washed out several times, 

and until repaired, the Weather Bureau gage was used. December 16, 1912, the 

present water-stage recorder was put in operation.

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

low water measurements have been made from a boat about 1,000 feet below the 

bridge.

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

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

16.15 feet at 10 a. m. February 25 (discharge, 110,000 second-feet); minimum 

stage from water-stage recorder, 0.79 foot at 9 a. m. September 30 (discharge, 1,340 

second-feet).

1902-1917: 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, 0.13 foot at 10 a. m. October 7,1913; 

(discharge, 790 second-feet).

DIVERSIONS. Minor diversion from tributaries above the station.

STORAGE. See North Fork of Feather River near Prattville, Calif.

REGULATION. The operation of the Big Bend plant of the Great Western Power Co. 

causes diurnal fluctuations in stage, especially during extremely low water, when 

it amounts to about a foot.

ACCURACY. Stage-discharge relation has not changed since May 12, 1915. Rating 

curve well defined above 1,400 second-feet. Operation of water-stage recorder 

satisfactory throughout the year. Daily discharge ascertained with discharge integrator or, for days of wide range in stage, by averaging results obtained by applying mean gage height of two-hourly intervals to rating table. Records excellent

MIDDLE FORK OF FEATHER RIVER AT SLOAT, CALIF.

LOCATION. Half a mile above Sloat, Plumas County, three-fourths mile above mouth 

of Poplar Creek, and about l\ miles below Cromberg.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. November 3,1910, to September 30, 1917.

GAGE. Gurley seven-day water-stage recorder on right bank installed September 11, 

1917. From December 5, 1913, to September 11, 1917, record is from a Gurley 

electric printing water-stage recorder; original gage at California White Pine Co.'s 

log chute at Cromberg. Several changes in gage at that site were made, but all 

gages were on downstream side of log chute piers and original datum maintained. 

Gage at new site has different datum. During construction of recorder well 

(November 9 to December 4, 1913) a staff gage was read at new site, new datum. 

Water-stage recorder inspected by George Langhorst.

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

CHANNEL AND CONTROL. Boulders and gravel; practically permanent. Left bank 

flat and timbered; submerged at flood stages.

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

6.75 feet at 10 p. m. March 29 (discharge, 4,040 second-feet); minimum stage, 

2.60 feet from 11 a. m. to 1 p. m. September 15 (discharge, 50 second-feet).

1910-1917: Maximum stage recorded, 13.0 feet April 7, 1911 (discharge, 9,640 

second-feet); minimum stage recorded, 2.2 feet September 17-29,1913 (discharge, 

44 second-feet).

ICE. Stage-discharge relation slightly affected by ice for very short periods.

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation has not changed since station was relocated in 

1913; not affected by ice 1916-17. Rating curve well defined below 6,000 secondfeet but extended above. Mean daily gage height determined by averaging 

readings from the printing water-stage recorder or by inspecting graph from the 

seven-day water-stage recorder. Daily discharge ascertained by applying mean 

daily gage height to rating table. Records excellent except those obtained by 

estimation, which are fair (see footnote to daily-discharge table).

YUBA RIVER AT SMARTSVILLE, 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, 6^ miles below mouth of South 

Fork, 7 miles above mouth of Dry Creek, and 18 miles above the junction with 

Feather River.

DRAINAGE AREA. 1,220 square miles.

RECORDS AVAILABLE. June 2, 1903, to September 30, 1917.

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 the gage datum was 

lowered 10 feet on 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. ,
SACRAMENTO RIVER BASIN. 225

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

the result of extensive mining in the early days, the channel has been filled witjh 

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, 18.0 feet at 8.15 

a. m. February 25 (discharge, 45,800 second-feet); minimum stage recorded, 1.95 

feet at 4.25 p. m. September 20 (discharge, 226 second-feet).

1903-1917: Maximum stage recorded, 28.3 feet January 15, 1909 (discharge, 

111,000 second-feet); minimum stage recorded, 3.23 feet October 5, 1913 (di£- 

charge, 216 second-feet); Bed of stream is being eroded so that stage becomes 

lower each year.

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

next paragraph.

REGULATION. Small lakes near the headwaters of the South Fork of Yuba are 

utilized as storage reservoirs. A part of this water is diverted into the Bear Riv^r 

drainage basin.

ACCURACY. Stage-discharge relation changed during high water of February 25, 

April 12, and June 4. Curves used from October 1 to February 25 and from June 

5 to September 30 are well defined; curves used between February 26 and 

June 4 are fairly well defined. Gage read to quarter-tenths once daily. Daily 

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

from February 25 to June 4 are fair; those for other periods are excellent.

NORTH FORK OF NORTH FORK OF YTTBA RIVER l AT DOWNIEVILLE, CALIF.

LOCATION. In NE. | NW. i sec. 35, T. 20 N., R. 10 E., at upper highway 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 1£ miles above station.

DRAINAGE AREA. 71.2 square miles.

RECORDS AVAILABLE. November 1, 1910, to September 30, 1917.

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 composed of gravel and small boulders. Since flood 

of May 11, 1915, control is the dam.

EXTREMES or DISCHARGE. Maximum stage recorded during year, 6.5 feet at 9 p. m. 

February 24 (discharge, 4,330 second-feet); minimum stage recorded, 2.4 feet 

October 15 to November 3 and November 10-16 (discharge, 59 second-feet).

1911-1917: Maximum stage recorded, 8.0 feetat 5 p. m. May 11,1915 (discharge 

from extension of rating curve, about 6,760 second-feet); minimum stage recorded, 

2.55 feet October 14-18, 1912 (discharge, 36 second-feet).

ICE. Stage-discharge relation slightly affected by ice for short periods in severe 

winters.

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

station.

REGULATION. See Accuracy.

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

flash boards on the dam and on the operation of the power plant which takes its 

water between the gage and dam. Observer has been instructed to read the gage 

when plant is not miming; it is usually shut down between about 7.30 a. m. and 

4.30 p. m. Stage-discharge relation was slightly affected by ice January 18-21. 

Rating curve for no boards on dam, well defined below 2,000 second-feet and is 

an extension above; curves for 12-inch boards on dam, well defined; for 18-inch 

boards on dam, fairly well defined. Gage read to half-tenths, sometimes hundredths, twice daily. Daily discharge ascertained by applying mean daily 

gage height to rating table. Records good.

COOPERATION. Gage-height record furnished by John T. Mason.

AMERICAN RIVER AT FAIROAKS, CALIF.

LOCATION. At highway bridge 1,500 feet northwest of Southern Pacific Co.'s railroad 

. station at Fairoaks Bridge, half a mile southeast of Fairoaks, Sacramento County, 

and 10 miles below mouth of South Fork.

DRAINAGE AREA. 1,910 square miles.

RECORDS AVAILABLE. November 3, 1904, to September 30, 1917.

GAGE. Gurley printing water-stage recorder on right bank 800 feet below bridge, 

installed January 18,1914. A temporary vertical staff gage on right bank about 40 

feet above bridge read October 1 to December 8,1916, and another temporary staff 

gage about 60 feet above the bridge read July 22 to September 30, 1917, by Edgar 

Cosby. These gages have independent, datums. Previous to installation of 

recorder, several staff gages at the right abutment of bridge had been used. 

The same datum has been maintained since station was established.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge, or by wading.

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

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

13.98 feet at 7.45 a. m. February 25 (discharge, 42,300 second-feet); minimum 

stage, 2.0 feet on temporary gage September 3-5, 14, 18 and 21 (discharge, 83 

second-feet). ,

1907-1917: Maximum stage recorded, 30.4 feet March 19, 1907 (discharge, from 

extension of rating curve, about 119,000 second-feet); minimum stage, 2.01 feet 

from 8 to 10.30 a. m. September 24, 1915 (discharge, from extension of rating 

curve, about 25 second-feet.)

DIVERSIONS. Water is diverted for irrigation above the station.

REGULATION. See descriptions of Middle, North, and South forks. Low-water flow 

partly regulated by power plant at Folsom.

ACCURACY. Stage-discharge relation changed February 25, 28 and April 12. Sand 

bar interfered with operation of recorder about July 21. Temporary staff gages 

were read from October 1 to December 8 and from July 21 to September 30. 

Rating curves developed when these gages were read are fairly well defined; 

rating curves used December 9 to July 21 are well defined. 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. For periods when recorder was not running (see footnote to 

daily-discharge table) discharge estimated from United States Weather Bureau 

gage heights at Folson by means of a relation curve. Records excellent when 

recorder was rtmning, good when staff gages were read, and fair for estimated 

periods.

MIDDLE FORK OF AMERICAN RIVER NEAR EAST AUBURN, CALIF.

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

1J miles above junction with North Fork of American River and 3J miles northeast of East Auburn, Placer County. I

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. October 22, 1911, to September 30, 1917.

GAGE. Staff in three sections on left bank at pump house; read by H. M. Power and 

J. A. Collins.

DISCHARGE MEASUREMENTS. Made from cable installed November 22, 1916, 700 feet 

below gage or by wading.

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

are high and not subject to overflow.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 13.0 feet at 7 a. m. 

February 25 (discharge, from extension of rating curve, 15,600 second-feet); 

minimum stage recorded, 1.5 feet at 8 p. m. September 1 (discharge, 50 secondfeet).

1911-1917: Maximum stage recorded, 18.0 feet at 7 a. m. January 1, 1914 (discharge from extension of rating curve,l about 26,400 second-feet); minimum stage 

recorded, 1.0 foot at 7 a. m. October 23, 24, and 31,1915 (discharge, 32 second-feet).

DIVERSIONS. Little South Fork ditch diverts from Gerle Creek into Pilot Creek 

drainage basin. Pilot Creek ditch diverts from Pilot Creek for irrigation on 

Georgetown divide. vThe former ditch is used to supplement the latter when 

the flow of Pilot Creek is not sufficient. Its maximum discharge is probably 

less than 20 second-feet.

REGULATION. 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 during floods of February 25 and 

April 26. Rating curve used October 1 to February 25, well defined below 7,000 

second-feet; curve used February 26 to April 26, well defined between 1,200 and 

5,000 second-feet; curve used April 27 to September 30, well defined below 7,000 

second-feet. Gage read to tenths once daily; oftener during high water. Daily 

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

Records good.

PUT AH CREEK BASIN. 

PTTTAH CREEK AT WINTERS, CALIF.

LOCATION. Just below Southern Pacific Co.'s railroad bridge at Winters, Yolo 

County, in Rio de los Putos grant.

DRAINAGE AREA. 805 square miles.

RECORDS AVAILABLE. September 26,1905, to September 30,1917.

GAGE. Staff in five sections on left bank, 600 feet below bridge; read by Miss Velma 

Wyatt. An auxiliary vertical staff on right bank is used for low water. Although 

set to the same datum it does not read the same as left-bank gage. The original 

datum has been maintained. A temporary gage was used from April 25 to July 

31, located 80 feet above the highway bridge and below a small Diversion for 

pumping on right bank. This gage is set to sea-level datum.
248 SURFACE WATER SUPPLY, 1917, PART XI.

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

CHANNEL AND CONTROL. Sand and gravel; somewhat shifting. Two channels at 

low water but the left channel usually carries very little water.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 29.0 feet at 3 

p. m., February 24 (discharge, from extension of rating curve, about 37,300 

second-feet); minimum stage recorded, 3.83 feet at 6 p. m., September 20 (dis-" 

charge, 1.0 second-foot).

1905-1917: Maximum stage recorded, 39.0 feet, December 31, 1913, from flood 

marks at gage (discharge, from extension of rating curve, about 60,000 secondfeet); no flow during parts of the years ending September 30, 1913 and 1914.

DIVERSIONS. There are several small diversions for irrigation above the station.

REGULATION. None.

ACCURACY. Stage-discharge relation changedg frequently during year. All curves 

are fairly well defined except the high-water curve which is an extension. Gage 

read to hundredths once daily and occasionally twice daily. Daily discharge 

ascertained by applying daily gage height to rating table or by shifting-control 

methods. Records good.

COOPERATION. Gage-height record April 25 to July 31 and some discharge measurements furnished by C. I. Rhodes.

-stage recorder, 6.81 

recorder, 3.50 feet at

LINK RIVER AT KLAMATH FALLS, ORE«.

LOCATION. In NW. I sec. 32, T. 38 S., R. 9 E., at county b;idge

at Klamath Falls. Klamath County, 1J miles below 

Lake, immediately above head of Lake Ewauna.

DRAINAGE AREA. 3,110 square miles.

RECORDS AVAILABLE. May 15, 1904, to September 30, 1917.

GAGE. Friez water-stage recorder on left bank, about 500

the NW. J sec. 32; elevation of zero is 4,080.0 feet above sesb level 

on opposite bank and a little farther upstream was used June 

30, 1912. Chain gage on the bridge used 1904 to 1908 

recorder was not working until 1914, when daily readings

over Link River, 

outlet of Upper Klamath

yards above bridge in 

Friez recorder 

6, 1908, to August 

and for periods when 

were discontinued.
258 SURFACE WATER SUPPLY, 1911, PART XI.

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

low water.

CHANNEL AND CONTROL. Rocks and boulders in rapids; mud and sand at bridge. 

The control for thfr gage is evidently permanent and water from the tailrace 

of California-Oregon Power Co.'s plant, which enters the river opposite the 

gage, appears to affect it the same as if it came down the river channel. The 

stage discharge relation at the chain gage is affected by backwater from Lake 

Ewanna, especially when the wind is blowing.

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

7.8 feet at 7 a. m. May 9 (discharge, 4,330 second-feet); minimum stage during 

year, 4.68 feet at 4 a. m. November 4 (discharge, 620 second-feet).

1904-1917: Maximum stage, 7.30 feet at gage at bridge May 12,1904, determined 

May 15, 1904, from high-water marks (discharge, 9,400 second-feet); minimum 

stage since September, 1912, 3.74 feet at 8 a. m. August 8, 1915 (discharge as 

estimated from downward extension of rating curve, about 200 second-feet). 

Minimum stage is due to effect of wind on Upper Klamath Lake, and river is 

said to have gone nearly dry at times.

ICE. Stage-discharge relation not affected by ice.

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

Reclamation Service diverts water from Link River immediately below the 

lower end of Upper Klamath Lake. For record of this diversion, see page 279. 

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. The only artificial regulation is caused by operation of power plant 

and is small. Marked natural fluctuations are caused by effect of wind on 'IFpper 

Klamath Lake.

ACCURACY. Stage-discharge relation for medium and high stages changed sometime 

between May, 1916, and March, 1917. Beginning October 1, 1916, new rating 

curve used which was fairly well denned between 1,000 and 4,000 second-feet, 

but somewhat uncertain for lowest stages. Operation of water-stage recorder 

satisfactory except December 30 to February 3, April 22 to May 8, and May 27 to 

June 4; partial record during these periods. Daily discharge for periods October 

1 to December 6 and July 1§ to September 30, ascertained by use of discharge 

integrator. Daily discharge for rest of year ascertained by applying to the rating 

table the mean daily gage height determined by inspecting gage-height graph. 

Records excellent February to April; fair October to January; good May to 

September. »

260 SURFACE WATER SUPPLY, 1917, PART XI.

KLAMATH RIVER AT SPENCER BRIDGE, NEAR KENO, OREG.

LOCATION. In sec. 32, T. 39 S., R. 7 E., at highway bridge about a mile below Spencer 

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

Klamath County, on road to Ashland.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. October 7, 1913, to September 30, 1917. 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, Bertha Spencer.

DISCHARGE MEASUREMENTS. Made from upstream side of wagon bridge or at low 

water by wading. The bridge is supported by bents 20 feet apart, center to center, 

resting on concrete footings about 2 feet wide and extending above high water. 

The upstream eni of these piers is immediately under the upstream handrail. 

The meter has generally been suspended from the upstream projection of certain 

floor beams where velocities have not been influenced by the piers. Measurements by wading have been made just above the bridge.

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

very even.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 2.10 feet May 10 

and 12 (discharge, 4,450 second-feet); minimum stage recorded, 0.03 foot September 25 (discharge, 963 second-feet).

1904-1917: Maximum stage recorded at Keno, 15.3 feet about May 10,1904, from 

high-water marks observed May 31 (discharge, 9,250 second-feet); minimum stage 

at Keno, 11.5 feet October 2, 1908 (discharge, 730 second-feet). Stage-discharge 

relation varied considerably at Keno station. The lowest discharge obtained as 

the result of a measurement was 680 second-feet (stage, 12.0 feet) November 3, 

1905.

ICE, Stage-discharge relation not affected by ice. 

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

At times water finds its way into Lower Klamath Lake through Klamath Straits; 

at other times the flow is into the river. Much of the winter flow of Lost River is 

diverted into Klamath River between Klamath Falls and Keno stations.

REGULATION. Some natural regulation due to effect of wind on the wide flat stretches 

of river above Keno.

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

defined and confirmed by current-meter'measurements, made in 1018. Gage read

to.hundredths three times a week. Daily discharge ascertained by applying

daily gage heights to rating table. Records good except those for extremely low

 water, which are only fair, owing to diurnal fluctuations.

COOPERATION. Field data furnished by United States Reclamation Service, J. B. 

Bond, project manager, Klamath project.

No discharge measurements were made at this station during the year.

SPRAGTJE RIVER NEAR YAINAX, OREG.

LOCATION. In NW. £ sec. 20, T. 36 S., R. 13 E., about 2 miles above highway bridge 

on road from Yainax to Silver Lake, 4 miles above mouth of Sycan River, and 

10 miles east of Yainax, Klamath County.

DRAINAGE AREA. 513 square miles. /

RECORDS AVAILABLE. April 19, 1912, to September 30, 1917.

GAGE. Stevens water-stage recorder on left bank; installed February 20,1914, at site 

of vertical staff gage, which was read about once a week prior to that date. Gage 

reader, L. F. Belknap. '

DISCHARGE MEASUREMENTS. Made from cable about 100 feet below gage; at high 

stages, from wagon bridge 2 miles downstream, and inflow estimated.

CHANNEL AND CONTROL. Bed composed of sand and gravel; control not well defined, 

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.

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

5.75 feet at 8 p. m. April 24 (discharge, 1,320 second-feet). Recorder indicated a 

minimum of 0.62 foot between November 26 and March 27 (discharge, 101 secondfeet).

1912-1917: Maximum stage recorded^is that of 1917; minimum stage, 0.6 foot, 

indicated by recorder between December 16, 1915, and February 16, 1916 (discharge, 100 second-feet). There was recorded at a station 2 miles downstream, on 

May 21, 1904, a discharge of 2,080 second-feet.

ICE. Stage-discharge relation seldom affected by ice, as stream is spring fed.

DIVERSIONS. Considerable water is diverted near Ely for irrigation.

REGULATION. None.

ACCURACY. Stage-discharge relation fairly permanent, except during summer, when 

it was affected by growth of aquatic plants. Well-defined rating curve used October 1 to June 16; transition curve, to allow for effect of aquatic growth, June l£to 

September 30. Water-stage recorder operated satisfactorily October 5 to November 25 and May 27 to July 5. No observer during winter; recorder did not run 

after July 5. Gage read once a day to tenths September 16-30. Records good, 

except those for July and August, which are poor because of fragmentary gage 

height record.

270 SURFACE WATER SUPPLY, 1917, PART XI.

SPRAGUE RIVER AT CHILOQUIN, OREG.

LOCATION.1 In NE. | sec. 3', T. 35 S., R. 7 E., half a mile above mouth and same distance above Southern Pacific Railroad bridge, where station was located up to 

October 31,1914, half a mile below diversion dam of Modoc Point canal of United 

States Indian Service, and about three-fourths mile south of Chiloquin, Klamath 

County.

DRAINAGE AREA. 1,550 square miles.

RECORDS AVAILABLE. July 25, 1911, to September 30, 1917; partly fragmentary.

GAGE. Friez water-stage recorder on right bank 500 feet above wagon bridge; installed 

June 25,1917. Vertical staff on wagon bridge was read November 1,1914, to June 

25, 1917, and a chain gage on railroad bridge up to October 31, 1914.

DISCHARGE MEASUREMENTS. Made from upstream side of wagon bridge.

CHANNEL AND CONTROL. Bed composed of rocks and boulders; heavy control; may 

shift slightly.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 5.3 feet at time of 

measurement April 27 (discharge, 4,490 second-feet); minimum stage from waterstage recorder, 1.00 foot at 2 p. m. July 31, caused by closing of sluice gate in 

diversion dam (discharge, 240 second-feet; including Modoc Point canal, 259 

second-feet).

1911-1917: Maximum stage recorded in 1917; minimum natural discharge, 

including Modoc Point canal, 293 second-feet September 1-5, 1915.

ICE. Stage-discharge relation affected by ice only during short periods of extremely 

cold weather.

DIVERSIONS. The Modoc Point canal, completed in 1915, diverted some water 

around the gage, of which a partial record was kept. A considerable quantity of 

water is also diverted for irrigation in the headwaters of Sprague and Sycan rivers.

REGULATION. Manipulation of sluiceway of diversion dam may cause some fluctuation at the gage.

ACCURACY. Stage-discharge relation practically permanent at each station. Rating 

curves well defined; that for old gage changed slightly at higk stages on basis of 

measurement of April 27. Gage read to hundredths up to June 23 on days for 

which discharge has been published. Operation of recorder satisfactory June 28 

to July 7 and July 20 to September 20. Daily discharge ascertained by applying 

to rating table the daily gage reading or the mean daily gage height obtained by 

inspecting the recorder graph. Records good June to September. Data inadequate for determination of monthly discharge prior to June.

SYCAN RIVER NEAR YAINAX, OREG.

LOCATION. In NW. J sec. 28, T. 35 S., R. 12 E., about 5 miles by stream above 

mouth and 16 miles northeast of Yainax, Klamath County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. November 25, 1911, to October 29, 1917, when station was 

moved 2 miles upstream.

GAGE. Stevens water-stage recorder on left bank; inspected by W. C. Robinson and 

L. F. Belknap. Vertical staff in sec. 3, T. 36 S., R. 12 E., about 3 miles below 

present gage, was used 1911 to 1913.

DISCHARGE MEASUREMENTS. Made from cable 15 feet upstream from gage, or by 

wading.

CHANNEL AND CONTROL. Stream bed gravel and sand; heavy growth of aquatic 

plants in summer; shifting. One channel at all stages; banks not subject to 

overflow.

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

11.25 feet about 8 a. m. Aprjl 25 (discharge, estimated from extension of rating 

curve, 2,250 second-feet); minimum stage indicated by water-stage recorder 

between October 12 and March 28 (clock stopped), 0.18 foot (discharge, 15 secondfeet). 

1911-1917: Maximum and minimum discharge are those of 1917.

ICE. Stage-discharge relation apparently not seriously affected by ice, as most of 

low-water flow comes from springs.

DIVERSIONS. Some water is used for irrigation by flooding Sycan Marsh.

REGULATION. None.

ACCURACY. Stage-discharge relation apparently permanent except during October, 

1916 and from June 14 to September 15, 1917, when it was affected by growth of 

aquatic plants. Rating curves applicable as follows: October 5-11, 1916 and 

June 14 to September 15, 1917, transition curve fairly well denned; March 28 to 

June 13, well denned below 700 second-feet; indirect method for shifting control 

used September 16 lo October 28,1917. Operation of water-stage recorder satisfactory beginning March 28 except June 19-24 and September 8-11. Daily discharge ascertained by applying to the rating table the mean daily gage height 

determined by inspecting recorder graph. Records good except those for 

last week in April, which are fair. /

KLAMATH RIVEK BASIN. 275

MODOO POINT CANAL NEAR CHILOQUIN, OREG.

LOCATION. In SE. \ sec. 3, T. 35 S., R. 7 E., at intake about a mile south of Chiloquin, Klamath County.

RECORDS AVAILABLE. June 14, 1915, to September 30, 1917.

GAGE. Inclined staff on left of concrete-lined section, about 100 feet below head 

gates; installed June 29,1915. Previous to that date readings were made on gage 

at bridge, one-half mile below.

DISCHARGE MEASUREMENTS. Made by wading. f

CHANNEL AND CONTROL. Earth section of canal begins immediately below gage; 

bottom width, 10 feet; grade, 2.64 feet per mile. Operation of controlling wasteway about a mile below apparently does not affe.ct stage-discharge relation at 

intake, but did have a material effect at the gage on the bridge.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 2.30 feet July 14 

(discharge, 43 second-feet). Canal dry at times; 95 second-feet was diverted 

July 10,1915, but most of it turned back into river at first wasteway.

ACCURACY. Stage-discharge relation practically permanent during season. Rating 

curve well defined. Gage read to quarter-tenths but not regularly. Daily discharge ascertained by applying gage reading to rating table. Canal dry from

LOCATION. In sec. 22, T. 33 S., R. 7J E., at highway bridge one-fourth mile east 

of Fort Klamath, Klamath County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. August 5, 1911, to September 30, 1917.

GAGE. Vertical staff attached to bridge; read by Mrs. E. A. Page.

DISCHARGE MEASUREMENTS. Made from highway bridge.

CHANNEL AND CONTROL. Clean graVel overlain with pumice sand, dunes of which 

may at times be observed moving downstream; likely to shift.

EXTREMES OF DISCHARGE. Maximum open-water stage recorded during year, 1.9 

feet May 1 (discharge, 370 second-feet); minimum discharge, 216 second-feet 

September 22, 23 and 26-30.

1911 and 1913-1917: Maximum stage recorded, 2.50 feet July 24/1913 (discharge, 495 second-feet, somewhat uncertain). The lowest stage on record is 

0.90 foot January 21-23, 1913 (discharge not computed).

ICE. Stage-discharge relation unaffected by ice, as most of the water comes from 

copious springs a few miles above. _

DIVERSIONS. Considerable water is diverted above station for watering hay lands, 

mostly in May and June.

REGULATION. None.

ACCURACY. Stage-discharge relation not permanent on account of log jams. Daily 

discharge ascertained by indirect method April 24 to September 30. Data 

inadequate for determination of discharge October 1 to April 23. Gage read 

once daily to half-tenths. Records good April to September.

RECORDS AVAILABLE. March 14, 1912, to September 30, 1917.

DRAINAGE AREA. Not measured.

GAGE. Vertical staff fastened to highway bridge. Zero of gage, 4,005.18 feet above 

sea level. Temporary gages used in 1917 but all readings reduced to datum of 

regular gage. Gage read by watchman for dam.

DISCHARGE MEASUREMENTS. Made from highway bridge.

CHANNEL AND CONTROL. Gravel and chalk rock; clean and fairly permanent.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 73.24 feet at 10 

a. m. April 25 (discharge 2,920 second-feet); minimum discharge estimated as 3 

second-feet (leakage through flashboards) November to March, inclusive.

1904-1916: Maximum stage recorded, 18.25 feet, mean for February 7, 1907, 

at Merrill station (discharge, 9,200 second-feet). The maximum stage for Olene 

station was 13.5 feet early in 1904, determined from high-water marks by John H. 

Lewis, May 24,1904 (discharge, from partly developed rating curve, 8,600 secondfeet). Minimum stage recorded for natural flow, 4.29 feet June 19, 1911, at 

Olene (discharge, 58 second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. This station is just below the dam at which practically all the discharge 

of Lost River up to about 500 second-feet is diverted through the diversion canal 

into Klamath River or into the G canal on the east bank of the river.

REGULATION. Changes in discharge covering several days may be caused at times 

by operation of the movable crest and outlet gates of the dam. Practically no 

water has ever reached this station from the area above the Clear Lake storage 

reservoir since June, 1909, when the dam was^closed.

ACCURACY. Stage-discharge relation changed about April 25, probably by sand filling 

in below gage on falling stage. Two fairly well defined rating curves used. 

Gage read to hundredths once daily while water was running. Daily discharge 

ascertained by applying daily gage height to rating table. Records only fair on 

account of diurnal fluctuations.

COOPERATION. Field data furnished by United States Reclamation Service.

TITLE LAKE NEAR MERRILL, OREG.

LOCATION. In sec. 8, T. 41 S., R. 11E., at boat landing on J. F. Adams's ranch, half 

a mile south of ranch building and 3 miles east of Merrill, Klamath County.

RECORDS AVAILABLE. May 17, 1904, to September 30, 1917.

GAGE. Vertical staff or pile driven in bed of Lost Eiver at a point which was formerly 

close to its mouth but is now nearly 2 miles from the open lake. Datum of gage, 

4,043.93 feet above sea level since September 22, 1916; all readings reduced to a 

-datum 4,000 feet above sea level. Several gages used prior to 3916; readings beginning October 1, 1912, refer to sea-level datum; earlier readings subject to some 

uncertainty of datum. Gage readers, employees of United States Reclamation 

Service.

EXTREMES OF STAGE. Highest stage during year occurred in April; it was considerably higher than the true water surface of Tule Lake, because of high velocity 

and consequent slope of river. Minimum stage recorded, 1.20 feet, or 4,045.13 

feet above sea level, September 29, 1917.

1904-1917: Maximum stage recorded, 11.35 feet April 30 and May 1, 1907, or 

4,059.91 feet above sea level. Mininmim stage recorded is that of 1917.
KLAMATH RIVER BASIN. 283

DIVERSION AND REGULATION. No water has reached the mouth of Lost River from 

drainage area above Clear Lake Dam since June, 1909; since May 1, 1912, most of 

the discharge .of Lost River up to 400 or 500 second-feet has been diverted at 

Lost River dam into Klamath River or through the "G" canal for irrigation.

MILLER GREEK NEAR LORELLA, OREG.

LOCATION. In sec. 7, T. 40 S., R. 14 E., at site of an old wagon bridge about threefourths mile above highway bridge, a mile east of Swingle ranch in Langell Valley, 

and 3 miles south of Lorella, KLamath County.

DRAINAGE AREA. 270 square miles.

RECORDS AVAILABLE. April 1, 1909, to September 30, 1917; August 10, 1904, to 

December 1908, for a station in sec. 12, T. 39 S., R. 13 E., at the lower end of 

Horsefly Valley and 10 miles or more by creek above the present station. Only a 

small amount of inflow between the two points.

GA.GE. Friez water -stage recorder on left bank attached to old bridge abutment until 

April 25, when installation was washed out. Recorder installed temporarily on 

right bank opposite original location on April 26. Gage inspected by A. I. Brooks.

DISCHARGE MEASUREMENTS. Made from highway bridge or, at low water, by wading; 

current is sluggish at the bridge, as the gradient of the stream is flat.

CHANNEL AND CONTROL. Stream bed composed of rocks and gravel overlain with some 

silt; control fairly permanent; left bank subject to overflow in floods.

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

8.85 feet at 8 a. m. April 26 (discharge, 2,970 second-feet); minimum stage from 

water-stage recorder, 2.60 feet October 1-13 (creek probably dry or nearly so).

1904-1917: Maximum stage recorded, 14.0 feet February 5, 1907 (discharge, 

6,730 second-feet).
284 SURFACE WATER SUPPLY, 1917, PART XI.

ICE. Stage-discharge relation apparently not materially affected by ice, as control 

remains open. Open-channel rating curve was formerly applied throughout the 

winter, but discharge for low winter stages in 1917 has not been computed.

DIVERSIONS. A small irrigating flume, carrying about 1 second-foot, diverts water 

above the station.

REGULATION. Flow may be occasionally affected by a rock and brush divenpon dam 

just above gage.

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

denned above 20 second-feet. Operation of water-stage recorder fairly satisfactory except for a few days in April and May. Daily discharge ascertained by 

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

recorder graph. Records fair:

OLENE WASTEWAY AT OLENE, OREG.

LOCATION. In SW. i sec. 14, T. 39 S., R. 10 E., at flume on F canal of Klamath 

project that crosses Lost River at Olene, Klamath County, about 4 miles upstream 

from Lost River dam.

RECORDS AVAILABLE. Irrigation seasons, 1915 to 1917.

GAGE. Records are kept of width of gate opening and of head of water on the orifice.

DISCHARGE MEASUREMENTS. Made in flume above and below wasteway, and difference between the two measurements taken as outflow from wasteway.

ACCURACY. Coefficient of discharge fairly well determined for discharge of 12 to 20 

second-feet; somewhat uncertain outside of these limits. Gage and gate opening 

recorded to half-tenth once a day. Records for total yearly run-off fair.

COOPERATION. Records furnished by United' States Reclamation Service.

No current-meter measurements were made during the year.

The Olene wasteway is used to supply water from Link River to supplement the 

flow of Lost River when the latter is insufficient to supply the G canal. The records 

are used in obtaining the total natural flow of Lost River.

LOST RIVER DIVERSION CANAL, NEAR KLAMATH FALLS, OREG.

LOCATION. At corner of sees. 25 and 36, T. 39 S., R. 9 E., and sees. 30 and 31, T. 39 S., 

R. 10 E., at wagon bridge about 10 miles southeast of Klamath Falls, Klamath 

County.

RECORDS AVAILABLE. May 1, 1912, to September 30, 1917.

GAGE. Two Gurley 7-day recorders; No. 1 installed at wagon bridge at station 85; 

No. 2 at a wagon bridge at station 330, or about 5 miles below No. 1. Gage readings have been recorded to same datum, which is 4,080 feet above sea level. 

Gage read by employees o^ U. S. Reclamation Service. .Gages above and below 

the intake gates at the Lost River dam, 1 in the SW. £ sec. 29, T. 39 S., R. 10 E., 

were read up to March 31,1916, and openings of the three gates recorded.

1 This station has been referred to as "Lost River diversion canal, near Olene."
286 SURFACE WATER SUPPLY, 191*7, PART XI.

DISCHARGE MEASUREMENTS. Made from a footbridge near southeast corner of sec. 30, 

about a mile above gage No. 1, and about one-half mile below intake of canal.

CHANNEL AND CONTROL. Artificial canal having a normal section about 50 feet wide 

on bottom, with side slopes 2 to 1, slope 0.00008, and designed to carry 4 to 5 feot 

depth of water. Klamath River backs water normally up to head of canal.

EXTREMES OP DISCHARGE. Maximum discharge during year, 390 second-feet March 

30.

1912-1916: Maximum discharge recorded, 508 second-feet February 28, 1914, 

for openings of 5.5 feet on all three gates and a head of 0.85 foot. Canal dry at 

times.

ICE. Stage-discharge relation unaffected by ice.

ACCURACY. Stage-discharge relation affected by backwater from Klamath River. 

Daily discharge ascertained according to the method outlined in Water-Supply 

Paper 345-E. 1 Individual discharge measurements, unless proper corrections are 

made for the slope in the water surface at the time of each measurement, plot 

discordantly. When the discharge is corrected to correspond to that which 

would occur for an average slope, these measurements develop a rating curve, 

called the "normal curve." This normal rating curve has been used in the 

determination of daily flow, the discharge for any given day as determined from 

this curve being corrected to correspond to the slope in the .water surface as 

obtained from the gage heights at gages Nos. 1 and 2. Normal rating curve is 

poorly defined. Water-stage recorders operated in a satisfactory manner except 

at gage No. 1, March 4-16, and at other times when operation of float may 

have been hampered by ice for short periods. 1 Reeords fair.

COOPERATION. Field data furnished by U. S. Reclamation Service.

Lost River diversion canal diverts water from Lost River into Klamath River to 

assist in lowering Tule Lake for the purpose of reclaiming the lake bed.

dam, 4 miles south of Olene, Klamath County. 

RECORDS AVAILABLE. Irrigating seasons, 1912 to 1917. 

GAGE. Stevens 8-day water-stage recorder 200 feet below the intake. 

DISCHARGE MEASUREMENTS. Made from wagon bridge 1,500 feet below intake. 

CHANNEL AND CONTROL. Canal is of regular section, 16 feet wide on the bottom and

practically permanent. Control not well defined; timber check at station 112

was not operated in 1917 to any considerable extent.
288 SUEFACE WATEE SUPPLY, 1917, PART XI.

EXTREMES OP DISCHARGE. Maximum stage recorded during irrigating season, May 

24 to September 29, 4.19 feet August 4 (discharge, 125 second-feet); maximum 

discharge, 159 second-feet at 4 p. m. June 16 (gage height, 3.94 feet). Minimum 

stage, 1.00 foot May 25 to 28 (discharge, 23 second-feet); minimum discharge, 15 

second-feet September 29 (gage height, 2.00 feet).

ACCURACY. Stage-discharge relation not permanent, being affected somewhat by 

operation of check, but mostly by growth of aquatic plants. Bating curve well 

defined and used May 24 to June 12. Daily discharge ascertained by indirect 

method for shifting control. Operation of recorder satisfactory except June IB29, J*ly 27-31, and August 18-31, when one reading daily on staff gage was used. 

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

height obtained by inspecting the recorder graph. Records fair.

COOPERATION. Field data and computations by United States Reclamation Service, 

Klamath project, J. B^Bond, project manager.

G canal diverts water from Lost River in the SW. } sec. 29, T. 39 S., R. 10 E., and 

irrigates land east of the lower part of the river and north of Tule Lake. Return

RELATING TO WATER RESOURCES.

^NTRODTJCTION.

Investigation of water resources by the United States Geological 

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

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

it has comprised also investigation of such closely allied subjects as 

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

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

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

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

coincide with natural drainage features as indicated below:

Part I. North Atlantic slope basins.

II. South Atlantic slope and eastern Gulf of Mexico basins.

III. Ohio River basin.

IV. St. Lawrence River basin.

V. Upper Mississippi River and Hudson Bay basins.

VI. Missouri River basin. 

VII. Lower Mississippi River basin. 

VIII. Western Gulf of Mexico basins.

IX. Colorado River basin. i

X. Great Basin.

XI. Pacific slope basins in California.

XII. North Pacific slope basins, in three volumes:

A, Pacific slope basins in Washington and upper Columbia River

basin.

B, Snake River basin. 

C, Lower Columbia River basin and Pacific slope basins in Oregon.

HOW GOVERNMENT REPORTS MAY BE OBTAINED OR CONSULTED.

NOTE. No data regarding stream flow are given in the 15th and 17th annual reports.

The records at most of the stations discussed in these reports 

extend over a series of years, and miscellaneous measurements at 

many points other than regular gaging stations have been made 

each year. An index of the reports containing records obtained 

prior to 1904 has been published in Water-Supply Paper 119.

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

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

to 1917. The data for any particular "station will in general be found 

in the reports covering the years during which the station was maintained. For example, data for Machias River at Whitneyville, Me., 

1903 to 1917, are published in Water-Supply Papers 97, 124, 165, 

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

contain records for the New England streams from 1903 to 1917. 

Results of miscellaneous measurements are published by drainage 

basins.

GAGING STATIONS. VH

In these papers and in the following lists the stations are arranged 

in downstream order. The main stem of any river is determined 

by measuring or estimating its drainage area that is, the headwater 

stream having the largest drainage area is considered the continuation of the main stream, and local changes in name and lake surface 

are disregarded. All stations from the source to the mouth of the 

main stem of the river are presented first, and the tributaries in 

regular order from source to mouth follow, the streams in each 

tributary basin being listed before those ok the next basin below.

In exception to this rule the records for Mississippi River are 

given in four parts, as indicated on page in, and the records for large 

lakes are taken up in order around the rim of the lake.

PRINCIPAL STREAMS.

The rivers draining into the Pacific Ocean from California include 

San Diego, San Dieguito, San Luis Rey, Santa Ana, San Gabriel, 

Los Angeles, Santa Ynez, Santa Maria, and Salinas rivers, draining 

areas south of San Francisco Bay; San Joaquin .River, whose chief 

tributaries are Kings, Merced, Tuolumne, Stanislaus, Calaveras, 

and Mokelumne rivers; Sacramento River, whose principal tributaries are Pit, Feather, and American rivers; and Russian, Eel, Mad, 

KLamath, and Smith rivers, which flow into the ocean north of San 

Francisco Bay. Except Klamath River, which receives the drainage 

from a small area in Oregon, and a few streams in Oregon that flow 

into Goose Lake, at the head of Pit River, all the streams in this 

division are entirely in California.

In addition to the list of gaging stations and the annotated list of 

publications relating specifically to the section, these pages contain 

a similar list of reports that are of general interest in many sections 

and cover a wide range of hydrologic subjects, and also brief references to reports published by State and other organizations. (See 

p. xxiv.)

the subject, traces the physical effects, past and future, of the hydraulic mining of earlier decades, 

the similar effects which certain other industries induce through stimulation of the erosion 

of the soil, and the influence of the restriction of the area of inundation by the construction 

of levees. Suggests cooperation by several interests for the control of the streams now carrying 

heavy loads of debris.

GEOLOGIC FOLIOS.

Under the plan adopted for the preparation of a geologic map of the United States 

the entire area is divided into small quadrangles, bounded by certain meridians 

and parallels, and these quadrangles, which number several thousand, are separately 

surveyed and mapped. 1 The unit of survey is also the unit of publication, and the 

maps and description of each quadrangle are issued in t|he form of a folio. When all 

the folios are completed they will constitute the Geologic Atlas of the United States. 

A folio is designated by the name of the principal town or of a prominent natural 

feature within the quadrangle. Each folio includes maps showing the topography, 

geology, underground structure, and mineral deposits of the area mapped and several 

pages of descriptive text. The text explains the maps and describes the topographic 

and geologic features of the country and its mineral products. The topographic 

map shows roads, railroads, waterways, and, by contour lines, the shapes of the hills 

and valleys and the height above sea level of all points in the quadrangle. The 

areal-geology map shows the distribution of the various jrocks at the surfaces. The 

structural-geology map shows the relations of the rocks to one another underground. 

The economic-geology map indicates the location of mineral deposits that are commercially valuable. The artesian-water map shows the depth to ground-water horizons. 

Economic-geology and artesian-water maps are included in folios, if the conditions 

in the areas mapped warrant their publication. The folios are of special interest to 

students of geography and geology and are valuable as guides in the development 

and utilization on mineral resources.

The folios numbered from 1 to 163, inclusive, are published in only one form (18 

by 22 inches), called the library edition. Some of the folios that bear numbers higher 

than 163 are published also in an octavo edition (6 by 9 inches). Owing to a fire 

in the Geological Survey Building May 18,1913, the stock of geologic folios was more 

or less damaged by fire and water, but many are usable, and will be sold at the uniform price of 5 cents each, with no reduction for wholesale orders. This rate applies 

to folios in stock from 1 to 184, inclusive; also to the library edition of folio 186. The 

library edition of folios 185, 187, and higher numbers sell for 25 cents a copy, except 

that some folios which contain'an unusually large amount of matter sell for 60 cents a 

copy. The octavo edition of folio 185 and higher numbers sells for 50 cents a copy. 

If 34 folios selling at 25 cents each (or their equivalent in higher-priced folios) are 

ordered at one time a discount of 40 per cent is allowed; $5.10 is the minimum amount 

accepted at this rate.

1 Index maps snowing areas in California covered by topographic'maps and by geologic folios will be 

mailed on receipt of request addressed to the Director, U. S. Geological Survey, Washington, D. C.
