SURFACE WATER SUPPLY OF PACIFIC SLOPE BASINS 

IN CALIFORNIA, 1916.

AUTHORIZATION AND SCOPE OF WORK.

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

measurements of flow made on streams in the United States during 

the year ending September 30, 1916.

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 bills passed by Congress have 

carried the following item and appropriations:

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

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

Annual appropriations for the fiscal years ending June SO, 1895-1917.

1911 to 1917, inclusive........................................... 150,000

In the execution of the work many private and State organizations 

have cooperated either by furnishing data or by assisting in collecting 

data. Acknowledgments for cooperation of the first kind are made 

in connection with the description of each station affected; cooperation of the second kind is acknowledged on pages 15 and 16.

Measurements of stream flow have been made at about 4,100 points 

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

Hawaiian Islands. In July, 1916, 1,290 gaging stations were being 

maintained by the Survey and the cooperating organizations. Many 

miscellaneous discharge measurements are made at other points.

10 SURFACE WATEE SUPPLY, 1916, PART XI.

In connection with this* work data were* also collected in regard to 

precipitation, evaporation, storage, reservoirs, river profiles, and 

water power in many sections of the country and will be made available in water-supply papers from. time to time. Information in 

regard to publications relating to water resources is presented in the 

appendix to this report.

DEFINITION OF TERMS.

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

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

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

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

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

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

They may be defined a& follows:

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

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

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

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

unit from which others are computed by the use of the factors given 

in the tables of convenient equivalents (p. 11).

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

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

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

regards time and area.

"Run-off (depth in inches)" is the depth to which an area would 

be covered if all the water flowing from, it in a given period were 

uniformly distributed on the surface. It is used for comparing runoff with rainfall, which is usually expressed in depth in inches.

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

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

The following terms not in common use are here defined:

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

of gage height to discharge."

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

stream below the gage which determines the stage-discharge relation 

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

same sectioD or sections at all stages.

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

gage the gage height to which the surface of the river would tall 

if there were no flow.

EXPLANATION OF DATA.

The data presented in this report cover the year beginning October 

1, 1915, and. ending September 30, 1916. At the first of January 

n 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, S) consists of records of stage, measurements of discharge, and general information 

used to supplement the gage heights and discharge measurements in 

determining the daily flow. The records of stage are obtained either 

from direct readings on a staff gage or from a water-stage recorder 

(PI. 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 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.
14 SURFACE WATER SUPPLY, 1916, PART XI.

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

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

of discharge measurements, a table showing the daily discharge of 

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

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

tables giving daily gage height and records of discharge measurements 

are published.

The description of the station gives, in addition to statements 

regarding location and equipment, information in regard to any conditions that may affect the 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 minimum 

recorded stages, and the accuracy of the records.

The table of daily discharge gives, in general, the discharge in secondfeet 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 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 OF FIELD DATA AND COMPUTED RECORDS.

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

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

of observation of stage, measurements of flow, and interpretation of 

records.

A paragraph in the description of the station or footnotes added 

to the tables gives information regarding the (1) permanence of the 

stage-discharge relation, (2) precision with which the discharge rating
COOPERATION. 15

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

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

rating table to obtain the daily discharge.

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

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

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

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

measurements with reference to the mean rating curve.

The monthly means for any station may represent with high 

accuracy the quantity of water flowing past the gage, but the figures1 

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

may be subject to gross errors caused by the inclusion of large noneontributing 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 

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 sources of error not known to the Survey.

The table of monthly discharge gives only a general idea of the 

flow at the station and should not be used for other than preliminary estimates; the tables of daily discharge allow more detailed 

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

to throw new light on data previously published.

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 1915-16 

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. Johns tone, president; Irving
16 ' SURFACE WATER SUPPLY, 1916, PART XI.

Martin, A. E. Chandler; Hiram W. Johnson, governor; and W. F. 

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

The entire expense of the stream-flow investigations in Tuolumne 

River drainage basin for the Hetch Hetchy project is paid by the 

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

engineer.

Assistance in the maintenance of river-measurement stations was 

furnished by the United States Forest Service, United States Weather 

Bureau, United States Indian Office, United States Bureau of Fisheries, Yosemite National Park, county of Los Angeles, Santa Barbara 

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

Sweetwater Water Co., Southern California Edison Co., the Turlock, 

Modesto, Oakdale, and South San Joaquin irrigation districts, and 

W. S. Post.

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 United States Indian Office, 

Goose Lake Valley Irrigation Co., and Rogue River Valley Canal Co.

SOUTHERN CALIFORNIA FLOODS OF JANUARY, 1916.

The rains that swept southern California in mid-January, 1916, 

fell upon ground which was already saturated. The water was 

therefore rapidly carried into the stream channels, producing torrents 

that overran their banks and devastated wide areas of the most 

fertile land in the State. In the following table is shown the crest 

discharge of streams in southern California for the floods in January, 

1916. Detailed information concerning the floods and the damage 

done is contained in Water-Supply Paper 426.1

intake of Dulzura conduit, and about 17 miles northeast of Dulzura, San Diego 

County. Pine Valley Creek enters 1 mile and Lyons Creek half a mile above the 

station.

DRAINAGE AREA. 246 square miles (measured on topographic maps).

RECORDS AVAILABLE. January 1, 1906, to December 31, 1915. Later records, collected by city of San Diego, withheld because of pending litigation.

GAGE. Two vertical staff gages have been in use since 1909. The upper, which is 

fastened to upstream face of dam on left bank, indicates depth of water on crest; 

the lower, which is fastened to upstream face of dasa between flume and right 

bank, at datum 2.50 feet lower than that of the upper gage, is read when no water 

is flowing over crest of dam. Previous to 1909 several gages with independent 

datums were.used.

DISCHARGE MEASUREMENTS. Made at low concrete dam back of which sand and 

gravel have been deposited to the level of its crest. At low stages the flow is 

restricted to a rectangular wooden flume through the wall of the dam, but at 

highs tages the flow is over the entire length of the crest, which is 61 feet. Measurements are made by wading except at high stages, when only float measurements have been obtained.

CHANNEL AND CONTROL. Bed of creek above and below dam composed principally 

of sand; shifting. Dam acts as artificial control for station.

EXTREMES OF DISCHARGE. 1906-1915: Maximum mean daily discharge, 5,800 

second-feet March 24, 1906; dry for several months every year since completion 

of Dulzura conduit in January, 1909.

DIVERSIONS. Dulzura conduit diverts water from Cottonwood and Pine Valley 

creeks, about half a mile above their junction, into Dulzura Creek drainage basin. 

Total monthly discharge of conduit: October, 1915, dry; November, 1915, 96 

acre-feet; December, 1915, 29.3 acre-feet.

REGULATION. Morena reservoir on Cottonwood Creek, about 8 miles above Barrett 

dam, has a capacity of 46,000 acre-feet. The stored water is released when needed 

for Dulzura conduit. January, 1, 1916, reservoir gage read 118.68 feet, showing 

15,900 acre-feet of storage.

COOPERATION. Records showing discharge in gallons per day furnished by the city 

of San Diego through F. M. Lockwood, manager of operation. Daily discharge 

converted into second-feet and monthly discharge computed by Engineers of 

United States Geological Survey.

Daily discharge, in second-feet, of Cottonwood Creek near Dulzura, Cal., for the period

Oct. 1 to Dec. 31, 1915.

SWEETWATEB RIVER BASIN. 

SWEETWATER RIVER NEAR DESCANSO, GAL.

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

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

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

RECORDS AVAILABLE. November 21, 1905 to September 30, 1916.

GAGE. Staff in three sections on left bank at concrete control, a short distance below 

intake of Ellis ditch; destroyed by high water January 23, 1916. February 18, 

1916, a vertical staff at an independent datum was fastened to large boulder on 

left bank 150 feet upstream from the gage washed out January 23; readings February 6-17 referenced to datum of this gage. Beginning June 11, 1916, gage readings were obtained from a new low-water section installed at site of gage destroyed 

January 23 with datum 0.93 foot lower than that of gage installed February 18. 

Gage read by C. H. Ellis.

CHANNEL AND CONTROL. Bed of channel composed of sand and fine gravel; shifting. 

Banks high in most places and not likely to be overflowed. October 11, 1914, a 

concrete control was constructed across channel opposite original gage; stage of 

zero flow, gage height of 0.5 foot, the elevation of lowest part of crest of control. 

Control was practically destroyed by flood in January.

EXTREMES OF DISCHARGE. Maximum stage during year, January 27 (discharge, 

9,870 second-feet, computed from cross section and slope); practically no flow 

during September.

1905-1916: Maximum stage. January 27, 1916; no flow during parts of 1910, 

1911, 1913, and 1916.

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

REGULATION. None.

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

curves used October 1 to January 2, January 13-23, February 6 to June 10, June 

11-17, and June 28 to September 30. Gage read to hundredths twice daily. 

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

shifting-control method used June 18-27. Records fair.

SWEETWATER RIVER AT SWEETWATER DAM, CAL.

The following table was prepared by J. F. Covert, chief engineer, 

Sweetwater Water Co., for court use. It is known as Exhibit L in 

the Neuman case and Exhibit J in the Sutliff case. Sweetwator 

reservoir is on Sweetwater River about 6^ miles northeast of National 

City, San Diego County. The drainage area tributary to the reservoir is 181 square miles (measured on topographic and military survey maps). The table shows the natural flow of Sweetwater River 

as computed from the run-off from the drainage basin stored in the 

reservoir, the waste through the blow-off, over the spillway and 

parapet, and through the breaks in the dam.

Discharge, in second-feet, of Sweetwater River at Sweetwater dam, Cal., for the period

Jan. 16-31, 1916.

SAW DIEGO RIVER AT LAKESIDE, CAL.

LOCATION. On El Cajon grant, just above ford on Lakeside and Padre Barona Valley 

road, three-fourths mile above Cuyamaca & Eastern Railroad bridge, and about 

1 mile above mouth of San Vicente Creek, three-fourths mile north of Lakeside. 

San Diego County.

DKAINAGE AREA. 203 square miles (measured on topographic maps).

RECORDS AVAILABLE. December 3, 1905, to September 30, 1916, when station was 

discontinued.

GAGE. Staff in three sections on left bank 100 feet above ford; location and datum 

unchanged since station was established. Gage read by J. H. Beadle.

DISCHARGE MEASUREMENTS. Made from cable at gage or by wading; equipment destroyed by flood in January.

CHANNEL AND CONTROL. Bed composed of sand; likely to shift with each change in 

stage. Banks fairly high and usually not subject to overflow, but right bank was 

overflowed during the January flood,for a considerable distance.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 12.6 feet at 5 p. m. 

January 27 (discharge not determined; see San Diego near Santee and at San 

Diego); no flow for several months during the year.

1906-1916: Maximum stage recorded January 27,1916; no flow for several months 

every year.

DIVERSIONS. Cuyamaca Water Co.'s flume heads at diverting dam about 1,000 feet 

below Boulder Creek and about 15 miles above station. Several pumping plants 

1 to 3 miles above the station obtain water for irrigation from wells along banks of 

stream.

REGULATION . Cuyamaca reservoir, on the headwaters of Boulder Creek, has a capacity 

of 11,400 acre-feet. See also Boulder Creek near Julian.

ACCURACY. Stage-discharge relation not permanent; greatly changed by the January 

floods. -Fairly well-defined rating curves were used February 1 to March 19 and 

May 8-27. Gage read to half tenths twice daily; more frequently during high 

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

table. For periods not covered by rating tables discharge was computed by 

shifting-control method, by interpolation between discharge measurements, and 

by comparison with record of flow near Santee. Total discharge for January computed from a study of the mean rainfall over the drainage area compared with the 

record at diverting dam and San Diego. Records fair.

SAN DIEGO RIVER NEAR SANTEE, CAL.

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

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

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

RECORDS AVAIL ABLE . May 25, 1912, to September 30, 1916 (record not complete).

GAGE. Staff in three sections; lower section is bolted to upstream face of old dam 

to the right of the break; other sections are on left bank just above dam; original 

location and datum have been maintained. Gage read by an employee of La 

Mesa. Lemon Grove & Spring Valley Irrigation District.
SAN DIEGO RIVER BASIN. 29

DISCHARGE MEASUREMENTS. Made from cable about 500 feet above gage or by wading; equipment destroyed by the flood in January, 1916.

CHANNEL AND CONTROL. Bed composed of sand; shifting. The old dam serves as a 

partial control. On May 10,1913, a concrete weir, having steel plates for crest and 

sides, was installed at the old break in the dam. This weir was partly destroyed 

February 2,1915. The flood of January, 1916, caused further damage to concrete 

weir and dam.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 25.1 feet about 6 

p. m. January 27 (discharge, computed from cross section and slope, 70,200 secondfeet) ; no flow for several months except for a small amount of ground water that 

rises to the surface at the dam.

1912-1916: Maximum stage recorded January 27, 1916; practically no flow for 

for several months every year.

DIVERSIONS. See San Diego River at Lakeside. Water for irrigation is pumped 

from wells along the river below Lakeside.

REGULATION. None except as explained for station at Lakeside.

ACCURACY. Stage-discharge relation fairly permanent during period covered by 

record. Fairly well defined rating curve used March 30 to May 27. Gage read 

to half tenths once a day. Daily discharge ascertained by applying gage height 

to rating table; discharge after May 27 computed by interpolation between 

discharge measurements, as there was no gage-height record. Records fair.

COOPERATION. Gage-height record March 30 to May 27 furnished by Charles Sampson, general manager La Mesa, Lemon Grove & Spring Valley Irrigation District.

BOULDER CREEK AT CtTYAMACA RESERVOIR, NEAR JULIAN, CAL.

LOCATION. In Cuyamaca grant, at outlet of Cuyamaca reservoir, 12 miles above 

mouth of Boulder Creek, and 7 miles south of Julian, San Diego, County.

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

RECORDS AVAILABLE. June 19, 1912, to September 30, 1916.

GAGE. Vertical staff fastened on right side of weir box, 3£ feet above weir. Zero 

at elevation of crest of the 6 foot Cippoletti weir 100 feet below outlet gates of 

reservoir. Gage read by W. J. Norman.

DISCHARGE MEASUREMENTS. Usually made by wading 50 feet below weir. On account of the velocity of approach, which is due to the head of the water in the 

reservoir, it has been necessary to rate the weir.

CHANNEL AND CONTROL. Cippoletti weir acts as permanent control.

EXTREMES OP DISCHARGE. Maximum mean daily discharge during year and period 

1912-1916, occurred January 28, 1916 (discharge, 1,877 second-feet); no flow 

during periods when water was not needed for Cuyamaca Water Co.'s flume.

ICE. No water is released from the reservoir during the winter season. Ice occasionally forms in Cuyamaca reservoir.

DIVERSIONS. None.

REGULATION. Flow completely regulated by operation of outlet gate of the reservoir. Cuyamaca dam, completed in 1886, was one of the first earth dams built 

in California to store water for irrigation. As originally constructed the dam was 

35 feet high; in 1894 it was enlarged so that the capacity of the reservoir was increased to 11,400 acre-feet. The present dam is 635 feet long and 41J feet high, 

and has an upstream slope of 2:1 and a downstream slope of 1J:1. From the reservoir the water flows down the natural channel of Boulder Creek and San DiegQ 

River to the intake of Cuyamaca Water Co.'s flume, 1 a distance of 12J miles.

i Formerly known as "San Diego flume."
32 SURFACE WATER SUPPLY, 1916, PART XI.

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. Record of daily discharge January 1 to September 

30 furnished by Cuyamaca Water Co. Records excellent when discharge does 

not exceed capacity of weir.

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

SAN DIEGO BIVEE BASIN". 33

BOULDER CREEK AT HOUTH, NEAR LAKESIDE, CAL.

LOCATION. In the NW. J sec. 12, T. 14 S., R. 2 E., just above junction with San 

Diego River, and about 14 miles northeast of Lakeside, San Diego County.

DRAINAGE AREA. 33.5 square miles (measured on topographic maps).

RECORDS AVAILABLE. August 12, 1912, to January 26, 1916, when station was discontinued.

GAGE. Vertical staff installed March 1, 1914, on right wing wall of weir box, 300 

feet above mouth of creek, at same datum as gage destroyed by^the flood in 

January, 1914; read by J. A. Mundy. When the station was established a weir 

without end contractions was installed. The gage, which was fastened to the 

left side of the box, was at same elevation as crest of weir. Weir board was 

removed November 9, 1912, and gage readings were obtained by measuring 

from a reference point until January 22, 1913, when a vertical staff was installed 

on left bank in pool above weir box at a datum 2.0 feet below that of original 

gage. Gage and weir were destroyed by flood January 27, 1916.

DISCHARGE MEASUREMENTS. Made from foot plank over flume or by wading.

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

acts as control. Banks fairly high and not likely to be overflowed.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 7.00 feet on afternoon of January 18 (discharge, about 345 second-feet); minimum stage, 0.98 

foot on afternoon of November 17 (discharge, 1.3 second-feet). 1912-1916: Maximum stage recorded January 18, 1916; no flow July 2-8, 1914.

DIVERSIONS . None.

REGULATION. Water is stored at Cuyamaca reservoir and released during low-water 

period. See Boulder Creek near Julian.

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

below 80 second-feet. Gage read twice a day to hundredths. Daily discharge 

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

for stages below 80 second-feet; high-water records roughly approximate.

The following discharge measurement was made by F. C. Ebert: 

December 8, 1915: Gage height, 1.08 feet; discharge, 2.2 second-feet.

Daily discharge, in second-feet, of Boulder Creek at mouth, near Lakeside, Cal., for ihc 

period Oct. 1, 1915, to Jan. 26, 1916.

CTJYAHAGA WATER CO.'S FLUME 1 AT DIVERTING DAM, NEAR LAKESIDE, CAL.

LOCATION. rln the SE. J sec. 11, T. 14 S., B. 2 E., just below intake, at diverting 

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

RECORDS AVAILABLJB. May 4, 1913, to September 30, 1916.

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 of gages, 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. Flume is lined with tar paper to reduce leakage. The 

elevation of the flume appears to vary slightly with the quantity of water flowing.

EXTREMES OF DISCHARGE. 1907-1916: Maximum daily discharge, 51 second-feet, 

March 24, 19KJ. No flow for certain periods nearly every year.

ACCURACY. Stage-discharge relation changes somewhat with the depth of water at 

intake. Bating curve after May 23 is well defined; earlier curves are fairly well 

defined. Gage read to hundredths three times a day. Daily discharge ascertained by applying mean daily gage height to rating table. Becords fair.

Cuyamaca Water Co. 's flume, which diverts water from San Diego Biver and receives 

also water from the South Fork of San Diego Biver is more than 30 miles long, 6 feet 

wide, and 24 inches deep. It discharges into La Mesa reservoir, about 8 miles northeast of San Diego. This system supplied the city of San Diego with water until 1906, 

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

The flume was again used to furnish water to the city of San Diego after the floods of* 

January, 1916, and it now supplies water for irrigation and domestic service. Area 

irrigated, about 4,000 acres.

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

this flume. At the sand box just below the gage water is occasionally wasted into 

San Diego Biver.. No water was wasted at this point after April 7, 1916.

36 SUEPAOE WATEB SUPPLY, 1916, PABT XI.

CUYAMACA WATER CO.'S FLUME i NEAR LAKESIDE, CAL.

LOCATION. At patrolman's cabin one-half mile above trestle crossing at Los Cochea 

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

miles below intake on San Diego River.

RECORDS AVAILABLE. January 1, 1907, to September 30, 1916.

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 the station was first 

established but the datum has remained same as elevation of floor of the flume. 

Gage read by an employee of Cuyamaca Water Co.

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

CHANNEL AND CONTROL. In the fall of 1914 the depth of the flume was increased 

8 inches and more tar paper lining put in. The elevation of the flume appears 

to vary slightly with the quantity of water flowing.

EXTREMES OP DISCHARGE. 1907-1916: Maximum mean daily discharge, 24 secondfeet, April 18, May 6-8 and 10-12, 1916. No flow certain periods every year.

ACCURACY. Stage-discharge relation varies with the amount of water flowing in the 

flume; when the discharge approaches full capacity the flume apparently settles 

slightly, but it returns to its original elevation when the flow decreases. Two 

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

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

height to rating table. No record February 1 to March 13; flume damaged by 

January floods and probably carried little or no water during this period. No 

gage heights reported May 12-22, 28-29, and 31; discharge interpolated. Records 

good.

There is a small diversion from this flume at Capitan Grande Indian Reservation 

above the station. Water is also diverted into the flume from South Fork of San 

Diego River. For location of intake, description of flume, and explanation of the 

use df the water, see description for Cuyamaca Water Co.'s flume at diverting dam 

near Lakeside.

38 SURFACE WATER SUPPLY, 1916, PART XI.

SAN DIEGTJITO RIVER BASIN. 

SANTA TSABEL CREEK NEAR MESA GRANDE, CAL.

LOCATION. In the NW. i sec. 21, T. 12 S., R. 2 E., at Sutherland dam site, about 1 

' mile below Sutherland, 1^ miles above m6uth 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, 1916.

GAGE. Friez water-stage recorder on right bank just above Sutherland dam site; 

destroyed by flood January 27, 1916; staff gage at same site was read January 

28 to February 28 and August 11 to September 21 by employees of the Volcan Land 

& Water Co.; Lietz water-stage recorder installed at same site March 18, 1916. 

Gage datum was lowered 0.31 foot April 21, on account of change in control.

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

destroyed by floods in January, 1916.

CHANNEL AND CONTROL. Bed composed of sand; shifting; concrete control, which 

had been constructed at an outcropping of bedrock 20 feet below gage damaged 

by floods in January, 1916, and repaired on July 1. Banks high, covered with 

brush, and not likely to be overflowed. Stage of zero flow, zero on gage.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 11.0 feet at noon 

January 27 (discharge, computed from cross section and slope, 21,100 secondfeet); minimum stage, 0.50 foot on August 14 (discharge, 1.4 second-feet).

1912-1916: Maximum stage recorded January 27, 1916; no flow 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 

the flood in January and construction changes in the concrete control in June. 

Daily discharge interpolated between frequent measurements for periods during 

which there was little change in stage and when record was affected by construction work at control. For other periods fairly well denned rating curves were used. 

The water-stage recorder was in operation October 1 to January 27, March 18 to 

August 10, and September 22-30. For the remainder of the year, the staff gage was 

read to hundredths once a day, except during high water, when more frequent 

readings were obtained. No gage-height record February 29 to March 16 discharge determined by comparison with records of flow for adjacent stations. 

Record fair.

SANTA YSABEL CREEK NEAR RAMONA, CAL.

LOCATION. In sec. 27, T. 12 S., R. IE., at Pamo dam site, 1| miles below mouth o

Temescal Creek, and about 4 miles north of Ramona, San Diego County. 

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

RECORDS AVAILABLE. February S, 1912, to September 30, 1916.
40 SURFACE WAITER SUPPLY, 1916, PART xi.

GAGE. Vertical staff fastened to solid rock on left bank at dam site; read by G. M. 

De Venelle; installed at an independent datum January 31,1916; gage previously 

used a staff in four sections on left bank, one-half mile upstream from site of 

present gage, and a short vertical section at concrete control destroyed by flood 

of January 16.( From January 17-30 observations were made by setting stakes at 

water surface and later referring them to gage datum by leveling.

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

washed out on January 17; reinstalled January 26, and washed out again on 

January 27.

CHANNEL AND CONTROL. Bed composed of sand; shifts somewhat both at original 

section and at dam site. On November 19, 1912, a concrete control was built 

about 30 feet below gage, but the floods of January, 1916, cut a new channel to th» 

left of the control.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 14.0 feet (referred 

to gage at dam site) at 7 p. m., January 27 (discharge computed from cross section 

and slope, 28,400 second-feet); minimum stage 1.02 feet October 10, 28, and 29 

(discharge, 1.4 second-feet).

1912-1916: Maximum stage recorded January 27, 1916; minimum stage, 0.74 

foot October 1-17, 1914 (discharge, 0.1 second-foot).

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

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

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

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

REGULATION. None.

ACCURACY. Stage-discharge relation fairly permanent until the new channel was 

formed by the floods in January, 1916. For the rest of the year the control at the 

dam site was somewhat shifting. Original gage read to hundredths three times a 

day; new gage read twice a day or more frequently during high water. Gageheight record January 1-15 lost during flood. Rating curves used October 1 to 

December 31, and February 1-24 well defined. Daily discharge for January 

determined from discharge measurements and comparison with record of flow at 

Mesa Grande; for rest of year discharge was determined by means of rating curves 

covering short periods, by shifting-control method, and by interpolation between 

discharge measurements. Records fair.

42 SURFACE WATER SUPPLY, 1916, PART XI.

KECORDS AVAILABLE. April 17, 1912, to January 16, 1916, when station "was 

discontinued.

GAGE. Chain gage fastened to upstream side of bridge near left bank; read by S. 

Cardej? Smith.

DISCHARGE MEASUREMENTS. Made from cable 30 feet above gage or by "wading.

CHANNEL AND CONTROL. Bed of stream composed of sand; shifting. Left bank subject to overflow at flood stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year and period 1912- 

1916, 21.0 feet at midnight January 16,1916 (discharge, about 11,000 second-feet); 

no flow several months every year.

DIVERSIONS. East and West San Pasqual ditches divert water for irrigation from the 

Santa Ysabel at the upper end of San Pasqual Valley (see Santa Ysabe'l Creek 

near Ramona). Water for irrigation is also pumped from wells along the river.

ACCURACY. State-discharge relation not permanent. Rating curve fairly well defined. Gage read to quarter tenths twice daily. Daily discharge ascertained by 

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

RECORDS AVAILABLE. January 17 to September 30, 1916.

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

DISCHARGE MEASUREMENTS. Made by wading near gage.

CHANNEL AND CONTROL. Bed composed of shifting sand overlying bedrock, which 

outcrops about 400 feet below gage; fairly permanent, except during low stages. 

Stage of zero flow, 0.42 foot.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 21.2 feet, from 1 

p. m. to 3 p. m., January 27 (discharge, computed from cross sections and slope, 

72,100 second-feet); no flow July 30 to September 30.

DIVERSIONS. See San Dieguito River at Bernardo.

REGULATION. None.

ACCURACY. Stage-discha^g relation fairly permanent except during low stages. 

Rating curves used Femuary 1 to March 19 and March 25 to May 18, well defined 

below 550 second-feet. Record of daily discharge January 16-31 furnished by 

W. S. Post; rest of record computed by shifting-control method. Gage read to 

hundredths twice daily; during high water more frequently. Daily discharge 

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

February 1 to May 18; fair for rest of year.

SANTA MARIA CREEK NEAR RAMONA, CAL.

LOCATION. In the SE. \ sec. 11, T. 13 S., R. 1W., about 7 miles below mouth of Hatfield Creek, and 5J miles West of Ramona, San Diego County.

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

RECORDS AVAILABLE. November 6, 1912, to September 30, 1916.

GAGE. Bristol water-stage recorder on right bank, with staff in two sections on 

opposite bank just above control. Water-stage recorder, Well, and house were 

destroyed by the flood on January 17, 1916. Staff gage was read January 16 to 

February 26 by employees of the Volcan Land & Water Co. Lietz water-stage 

recorder, at same site as previous recorder, used March 4 to July 18, 1916.

DISCHARGE MEASUREMENTS. Made from cable 100 feet below gage or by wading; 

equipment destroyed by the floods in January, 1916.

CHANNEL AND CONTROL. Bed above and below station composed of sand; shifting. 

Concrete control installed just below gage at an outcropping of solid rock. Stage 

of zero flow; gage height 1.32 feet. Left bank high; right bank may be overflowed during extremely high water. About 1,000 feet below gage valley narrows to a rocky gorge at proposed dam site. Onv this account there is natural 

storage in the channel during extremely high water. Control was not injured 

by the floods of January, 1916.

EXTREMES OF DISCHARGE. Maximum stage during year and period 1912-1916, determined by leveling from flood marks, 15.9 feet at 5 p. m. January 27, 1916 (discharge computed from cross section and slope, 7,140 second-feet); no flow for 

several months every year.

DIVERSIONS. None.

REGULATION . Noae.
46 SURFACE WATER SUPPLY, 1916, PART XI.

ACCURACY. Stage-discharge relation fairly permanent. Eating curves well defined 

except for high water. Daily discharge for periods in which water-stage recorder 

was in operation ascertained by applying to the rating table mean daily-gage 

height determined by inspecting gage-height graph. Staff gage read to halftenths once daily, January 16 to February 6 and February 14-26, except during 

flood stages, when more frequent readings were obtained. Eecords for high 

water, fair; for other stages, good.

SAN LTJIS BEY BIVEB BASIN.

SAN LTTIS KEY RIVER 1 NEAR WARNER SPRINGS, CAL.

LOCATION. In the NE. J sec. 17, T. 10 S., B. 3 E., in San Jose dej Valle grant, about 

3J miles above junction with West Fork of San Luis Rey River, and 4 miles 

northwest' of Warner Springs, San Diego County.

DRAINAGE AREA. 35.8 square miles (measured on topographic map).

RECORDS AVAILABLE. January 25, 1913, to November 18,1915. Occasional discharge 

measurements until June 27, 1916, when station was discontinued.

GAGE. Sanders & Rising water-stage recorder on left bank with staff in two sections 

on opposite bank; equipment destroyed by the floods in January, 1916. A temporary gage was established February 11,1916, but was read only when discharge 

measurements were made.

DISCHARGE MEASUREMENTS. Made by wading near gage.

CHANNEL AND CONTROL. Bed eomposed of sand; shifting. Concrete control built 

across the channel just below gage has not been very effective on account of accumulation of sand.

EXTREMES OP DISCHARGE. 1913-1915: Maximum stage recorded, about 4.0 feet 

crest of flood of January 27, 1914 (discharge, 233 second-feet); minimum stage 

recorded, 2.2 feet August 23-25, 1914 (discharge, 0.4 second-foot).

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stage-discharge relation not permanent. Change in stage was slight

SAN LOTS REY RIVER NEAR MESA GRANDE, CAL.

LOCATION. In the NE. \ sec. 9, T. 11 S., R. 2 E., 1 mile below Warner dam site, 1 

mile below mouth of Carrizo Creek and about 5 miles north of Mesa Grande, 

San Diego County.

DRAINAGE AREA. 209 square miles (measured on topographic maps).

RECORDS AVAILABLE. Octobers, 1911, to September30, 1916.

GAGE. Barrett & Lawrence water-stage recorder on left bank just above weir; 

removed by flood during night of January 16-17, 1916. Staff gage was read 

until Lietz water-stage recorder was installed on May 1, 1916. Vertical staff 

installed at weir March 18, 1915, for use during low water; datum same as waterstage recorder. Previous to June 13, 1912, gage was just above cut-off wall at 

dam site. Original datum has not been maintained.

DISCHARGE MEASUREMENTS. Made from (Sable about 1 mile above gage or by wading.
SAN LUIS EEY EIVEB BASIN. 49

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

Concrete weir which served as a control was destroyed by floods in January, 1916.

EXTREMES OF DISCHARGE. Maximum stage during year, 18.0 feet at 4.30 p. m., 

January 27 (discharge, computed from slope and cross section, 58,600 second-feet); 

minimum stage from water-stage recorder, 0.81 foot September 2 (discharge, 1.4 

second-feet).

1911-1916: Maximum stage recorded January 27, 1916; minumum stage recorded, 0.09 foot August 31, .1914 (discharge estimated at 0.2 second-foot).

DIVERSIONS. None.

REGULATION. None.

ACCURACY. Stagje-diseharge relation not permanent as sand collects at weir. Mean 

> daily gage heights October to December and May to September determined by 

inspecting gage-height graph; staff gage read frequently except during the 

night, January 16-31, and three times a day February. 1 to April 30. Record 

from water-stage recorder January 1-15 lost; gage-height record for this period 

is fragmentary. Daily discharge computed by interpolation between frequent 

measurements when change in stage was slight, by shifting-control method when 

stage-discharge relation was changing, and read directly from rating curves 

covering short periods; daily discharge, January 16-31, computed from hydrograph. Records good.

SAN LTTIS REY RIVER NEAR NELLIE, CAL.

LOCATION. In Potrero Indian Eeservation (near west line of sec. 33, T. 10 8., R. 1 E., 

unsurveyed), above intake of Escondido Mutual Water Co.'s canal; about 4$ 

miles southwest of Nellie, San Diego County, and 8 miles below gaging station at 

Warner dam site near Mesa Grande. ,

DRAINAGE AREA. 240 square miles (measured on topographic maps).

RECORDS AVAILABLE. October 1, 1915, to June 30, 1916, when station was discontinued (not complete).

GAGE. Friez water-stage recorder on left bank, with reinforced concrete well, 500 

feet above intake of Escondido Mutual Water Co.'s canal; equipment destroyed 

by the floods in January, 1916; temporary staff installed March 10 at independent 

datum; June 16 datum was lowered 1.88 feet. Gage read by W. C. Eddy, April 1 

to June 30.

DISCHARGE MEASUREMENTS. Made from cable 400 feet above gage or by wading; 

equipment destroyed by the floods in January, 1916.

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

A concrete control extending to bedrock, built across channel 30 feet below gage, 

was destroyed by the floods in January, 1916. ,

DIVERSIONS . None.

REGULATION. None.

ACCURACY. Stage-discharge relation not permanent, as sand collects at control, 

Mean daily gage heights determined by inspecting gage-height graph, October 15 

to January 8; April 1 to June 30, gage read once a day to hundredths. Daily 

discharge October 1-14 estimated from discharge measurements, as water-stage 

recorder was not installed until October 15; October 15 to November 3, by shiftingcontrol method, on account of changes in channel; November 4 to December 3, 

from an average rating curve fairly well denned; December 4 to January 8, by 

shifting-control method; January 9-14, by comparison with record of flow at 

Mesa Grande as gage-height record was lost; January 16-31 from detailed study 

of mean precipitation computed for drainage area and by comparison with other 

records on San Luis Rey River; no gage-geight record during February and March; 

April 1 to June 30 from well-defined rating curves, discharge interpolated for 

days when gage was not read. Records good for low and medium stages; highwater record fair.

SAN LUIS BEY EIVEB BASI1T. 53

SAN LUIS RET RIVER NEAR PALA, CAL.

LOCATION. In the NW. \ sec. 31, T. 9 S., R. 1W., above ford on road to Sickler's mill, 

about 4 miles southeast of Pala, San Diego County.

DRAINAGE AREA. 322 square miles (measured on topographic maps).

RECORDS AVAILABLE. October 9, 1903, to June 20, 1911, and November 14, 1912, to 

January 31, 1916, when station was discontinued.

GAGE. Friez water-stage recorder on left bank 600 feet above ford and staff gage in 

three sections at same site. Gage used previous to September 19, 1912, was staff 

about 50 feet above ford; datum,of original gage was lowered 4.66 feet November 

13, 1906. New gage above cable is at an independent datum. Water-stage 

recorder was removed by the high water in January, 1916. No gage-height record 

after January 16, 1916.

DISCHARGE MEASUREMENTS. Made from cable 550 feet below water-stage recorder 

or by wading.

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

On September 19, 1912, an artificial control, consisting of short concrete cut-off 

walls between the boulders, was built across channel just below gage; control 

damaged by the flood in 1914 and rebuilt September 28, 1914. Stage of zero 

flow for new control, about gage height 5.7 feet.

EXTREMES OP DISCHARGE. Maximum stage during year, 18.1 feet probably on 

January 27, determined by leveling from flood marks (discharge, estimated by 

U. S. Indian Service, from slope and cross section below Agua Tibia Creek, 

75,000 second-feet); minimum stage recorded, 5.92 feet October 8-10 (discharge, 

4.5 second-feet).

1903-1916: Maximum stage recorded January, 1916; minimum stage, 5.28 feet 

August 6 and 7, 1907 (discharge, 0.6 second-foot).

DIVERSIONS. Water is diverted for irrigation on the Rincon Indian Reservation. 

The Escondido Mutual Water Co. diverts water from San Luis Rey River about 

10 miles above the station. This water, which is stored at the Escondido reservoir 

(capacity, 3,120 acre-feet) about 6 miles northeast of Escondido, is used for irrigation and municipal supply at Escondido and vicinity. Water is diverted from 

Pauma Creek for irrigation on the Pauma Indian Reservation and Pauma Rancho. 

About 1 second-foot of water is diverted above the station for irrigation of the 

orchard at Sickler's mill on left bank below station.

REGULATION. None.

ACCURACY. Stage-discharge relation practically permanent, though a little sand 

collects at control during low water. Concrete control was destroyed by the 

floods in January, 1916. Two fairly-well defined rating curves were used October 

1,1915, to January 16,1916. Daily discharge of this period ascertained by applying 

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

graph; discharge, January 17-31 estimated from mean rainfall computed fpr 

drainage area and by comparison with records of flow at Mesa Grande and Oceanside. Records good, except for January floods.

LOCATION. In the SW. \ NW. \ sec. 33, T. 10 S., R. 1 E., 500 feet below intake on 

San Luis Rey River, about 3J miles above Rincon Indian Reservation, 4 miles 

' southwest of Nellie, San Diego County, and 15 miles northeast of Escondido.

RECORDS AVAILABLE. October 1, 1896, to September 30, 1916, except that tfiere 

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

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

DISCHARGE MEASUREMENTS. Made from plank afcross canal or by wading at various 

sections near gage.

CONTROL. Rectangular weir with 6-foot crest length, 500 feet below intake. October 

29, 1915, wooden weir board was replaced by concrete slab with steel plate for 

crest; length of crest not changed. March, 1916, Mr. E. R. Bowen installed a 

weir at south portal of tunnel No. 2 and developed rating curves for the various 

crude weirs which had been used in previous years.

COOPERATION. Gage-height record and rating table furnished by Escondido Mutual 

Water Co. Daily and monthly discharge computed by engineers of the U. S. 

Geological Survey.

The canal, which is 5.6 miles long, consists of flume, ditch, and tunnel sections 

constructed through a very rough, mountainous country. It discharges into a reservoir about 6 miles northeast of Escondido. The dam, which is 76 feet high and 380 

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

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

and vicinity.

DRAINAGE AREA. 189 square miles (measured on topographic map); 182 square miles 

at original site above Warm Springs Canyon.

RECORDS AVAILABLE. July 1, 1896, to September 30, 1916.

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

power house; installed October 18, 1912, independent datum; old staff, at upper 

station near ford, read November 24 to January 16,1916. Several gages at approximately the same site but(at independent datums have been used. All equipment 

destroyed by floods in January, 1916. February 11, 1916, new gage, independent 

datum, was installed about 10 feet below gage in use at beginning of year. Gage 

read by E. Givens.

California Edison Co.'s power plants Nos. 1 and 2 are 5J and 2| miles, respectively, 

above the Mentone plant of the Pacific Light & Power Corporation at the mouth 

of the panyon.

ACCURACY. Stage-discharge relation permanent except during floods. Well-defined 

rating curves used October 1 to November 23 and February 11 to September 30; 

curve used November 24 to January 16 well defined below 20 second-feet. Gage 

read once daily to hundredths. Daily discharge ascertained by applying gage 

height to rating table. Records February 11 to September 30, good; previous 

records fair.

SANTA ANA RIVER AT SAN BERNARDINO, CAL.

LOCATION. At Salt Lake Street Bridge (E Street), San Bernardino, San Bernardino 

County.

MAXIMUM DISCHARGE IN JANUARY, 1916. Mr. H. B. Andrews, Riverside Water Co., 

obtained cross-section and slope data from high-water marks which he observed 

during the storm of January 17, and has estimated the discharge as follows: Area, 

2,020 square feet; wetted perimeter, 251 feet; slope, 0.006; discharge, 40,000 

second-feet. The high-water marks January 27 were practically the same as on 

January 17.

The following discharge measurements at Salt Lake Street bridge, furnished by 

Riverside Water Co., include the flow of San Timoteo Creek and Redlands Wash but 

do not show diversions by Gage canal at Sterling Street.

Discharge measurements of Santa Ana River at San Bernardino, Col., during January,

PACIFIC LIGHT & POWER CORPORATION'S CANAL AND GREENSPOT PIPE LINE

NEAR MENTONE, CAL.

LOCATION. At tailrace of Pacific Light & Power Corporation's plant at mouth of

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

of Mentone, San Bernardino County. 

RECORDS AVAILABLE. 1896 to September 30, 1916. 

GAGE. Hook gage at weir on right bank of Santa Ana River, about 300 feet west of

power house. Flume and weir were destroyed by the flood in January, 1916. 

DISCHARGE. Computed from gage heights which give head on 10-foot rectangular

weir. March 29 to September 30, computed from record of power developed. 

EXTREMES OP DISCHARGE. 1896-1916: Maximum mean daily discharge recorded

1896-1916, 97 second-feet, March 16, 1905; no flow during periods in nearly every

year. 

DIVERSIONS. Water diverted from the forebay by the Greenspot pipe line; must be

added to give total flow of canal. The pipe line was put in operation September

7, 1911. 

ACCURACY. Records good.

The intake of the Pacific Light & Power Corporation'8 canal is at Southern California Edison Co.'s power plant No. 2, 2| miles above the Mentone plant of the Pacific 

Light & Power Corporation at the mouth of the canyon. The water diverted, except 

that taken by the Greenspot pipe line, is first used for power development; after the 

water leaves the Mentone power house it is conducted across Santa Ana River in a 

flume and discharged into a lined canal; it is then distributed for irrigation. It is 

interesting to note that before the water enters the irrigation canal it has passed 

through three power plants.

LYTLE GREEK NEAR SAN BERNARDINO, CAL.

LOCATION. In the NW. J sec. 25, T. 2 N., R. 6 W., at Southern California Edison 

Co.'s diversion dam, below junction of North and Middle forks of Lytle Creek, 

in Angeles National Forest, about 3 miles above mouth of canyon and 14 miles 

northwest of San Bernardino, San Bernardino County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. September 18, 1904, to September 30, 1916.

GAGE. Watson water-stage recorder in pool above weir in power canal.

DISCHARGE. Computed by combing determinations of flow in power canal with those 

of flow over diverting dam; discharge of power canal is measured near intake by 

an 8-foot steel plate rectangular weir; flow over diverting dam is estimated.

EXTREMES OF DISCHARGE. 1904-1916: Maximum mean daily discharge reported, 

4,750 second-feet January 18, 1916; minimum mean daily discharge, 5.1 secondfeet September 30 and October 3, 1904. The discharge at 6 a. m. January 18, 

1916, was estimated at 8,000 second-feet.

DIVERSIONS. No information.

REGULATION. No information.

ACCURACY. Daily discharge is mean of two observations recorded every day at 6 a. 

m. and 6 p. m. Records for periods in which total flow of Lytle Creek is diverted 

into power canal, good; for those in which discharge exceeds 23 second-feet 

(capacity of canal) they are roughly approximate.

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

through H. W. Dennis, construction engineer.

LYTLE CREEK AT SAN BERNARDINO, CAL.

The following table was compiled from a blue-print hydrograph which was furnished by J. A. Sourwine, county engineer, and which was prepared from measurements of East and West channels of Lytle Creek. The West channel was measured 

at new Fourth Street bridge until the bridge was washed out at 8.05 a. m., January 

18; later measurements were made at Atchison, Topeka & Santa Pe Railway Co.'s 

bridge, North Colton. The East channel was measured at old Fourth Street bridge 

until about 9 a. m., January 18, and later at Mount Vernon Avenue bridge. Dis-

SAN JACINTO RIVER NEAE ELSINORE, GAL.

LOCATION. Near east line sec. 9, T. 6 S., E. 4 W., about 2 miles above junction 

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

and 2 miles southeast of Elsinore, Riverside County.

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

RECORDS AVAILABLE. January 1 to September 3p, 1916.

GAGE. Vertical staff in two sections on rigfet bank about one-fourth mile above 

highway crossing. From January 1 to February 12, gage was a vertical staff at 

railway bridge, three-fourths mile downstream; readings on this gage were 

affected by backwater from Elsinore Lake beginning about January 30. Gage 

read by W. L. Wilhite.

DISCHARGE MEASUREMENTS. Made from railway bridge three-fourths mile bek>tf 

gage or by wading below gage.

CHANNEL AND CONTROL. Bed composed of gravel and small boulders; apparently 

permanent. One channel at all stages.

EXTREMES OP DISCHARGE. Maximum stage'recorded during year, 19.0 feet at 11 

, a. m., January 28 (discharge, computed from cross section and slope, 14,000 

second-feet); channel dry July 28 to August 9.

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

Water is also diverted above San Jaeinto for irrigation.

REGULATION. Water is stored for irrigation at Hemet Reservoir on South Fork San 

Jaeinto River. ' S,

ACCURACY. Stage-discharge relation for original gage at railway bridge affected by 

backwater from Elsinore Lake beginning January 30. Station moved upstream 

three-fourths mile February 13, where stage-discharge relation is apparently 

permanent. Rating curve for original gage fairly well defined by two mediumstage measurements and flood discharge computed from cross section and slope; 

rating curve for new gage well defined throughout. Gage read once daily to 

hundredths during low and medium stages. Records January 1 to February 12 

fair; those for rest of year good.

ELSINORE T.A1TB! AT ELSINORE, CAL.

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

RECORDS AVAILABLE. December 1, 1915, to September 30, 1916.

GAGE. Vertical staff in several sections, on northeast shore a short distance above 

outlet; read by W. L. Wilhite. Zero of gage 1,200 feet above mean sea level.

HISTORY.l Apparently the earliest specific reference to the amount of water in 

Elsinore Lake is that contained in the notes of a traveler through southern California about 1810, who mentions "Laguna Grande," the original Mexican 

name for the lake, as being little more than a swamp about a mile long. For 

the period between that time and 1862 data as to its rise and fall are not available,

i Prepared in 1916 by Francis R. Schanck, assistant inspector of irrigation, United States Indian Office, 

Los Angeles, Cal.; first published in TJ. £. Geol. Survey Water-Supply Paper 426, pp. 71-72,1917.
SANTA ANA EIVEE BASIN. 73

but in 1862 it was very high and probably overflowed. During the succeeding 

dry period, especially during the years 1866 and 1867, when practically BO rain 

fell on the drainage area tributary to the lake, it receded very rapidly, but it 

was full again in 1872 and overflowed down its outlet through Temescal Canyon. 

After this it again evaporated down to a level probably as low as it has ever been 

since, but the rains of the winter of 1883-84 filled it to overflowing in three weeks.

Americans had settled around it by this time, and their descriptions of conditions say that large willow trees surrounding the low-water shore line were 

of such size that they must have been 30 or more years old. The rainfall in the 

next 10 years was excessive and the lake stayed high and overflowed naturally 

during three or four years of the decade. It was purchased by the Temescal 

Water Co. for the irrigation of lands at Corona, and its outlet channel was deepened, permitting gravity flow to Corona for a year or more after the lake level had 

sunk below the elevation of its outlet. As the surface still receded a pumping 

plant was installed and the water was raised a maximum of about 10 feet, then 

flowing down the natural channel of Temescal Canyon. Pumping was continued 

a season or two, but the concentration of salts in the lake, due to the evaporation 

and low rainfall, soon made the water unfit for irrigation.

After 1893 the water level sunk almost continuously for nearly 10 years, though 

rising slightly, of course, every winter. The heavier precipitation Beginning 

in 1903 gradually filled the lake to about half the depth between its minimum 

level since 1883 and its high level or overflow point. The flood of January, 1916, 

- rapidly raised the level to overflowing although the run-off into the lake appears 

to have been considerably less than that of the wet years of 1883-84 and 1888-89.

The fact that large trees were growing 20 feet or more below the high-water 

level when the lake filled in 1883-84 indicates that the high water of the sixties 

and seventies must have been of very short duration. The stumps of the trees 

were still visible in 1888 and 1889 many hundred feet from shore, but by the time 

the lake receded in the middle nineties these had disappeared.

SO, 1916.

NOTE. This table computed by engineers of United States Geological Survey.
SURFACE WATER SUPPLY, 1916, PART XI. 77

SAN GABRIEL RIVER BASIN.

SAN GABRIEL RIVER NEAR AZUSA, CAL.

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

canyon, about half a mile above Pacific Light & Power Corporation's power 

house, and 2 miles north of Azusa, Los Angeles County.

DRAINAGE AREA. 222 square miles.

RECORDS AVAILABLE. 1894 to September 30, 1916.

GAGE. Staff in two sections on left bank at a rock point above ford; read January 2 

to April 4, except January 2-8 and 12-16, when the water did not reach it, and a 

vertical staff on left bank 600 feet below ford was read; April 5 to June 24, vertical 

staff, at independent datum, 50 feet above regular gage above ford. Original gage 

was just above ford at mouth of canyon, but owing to frequent changes in channel 

it has been necessary to make numerous changes in the gages, which have varied 

 in position from 1,000 feet above ford to 600 feet below and most of which have 

been installed at independent datums. Gage read by Vickrey and Bunje.

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

near gage. *

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

water.

EXTREMES OF DISCHARGE. Maximum stage recorded during year and period 1894 

1916, 12.0 feet at 7 a. m. January 18, 1916 (discharge, 40,000 second-feet); no flow 

for several months each year.

DIVERSIONS. Power canal of Pacific Light & Power Corporation heads about 5 miles 

above station. Water was diverted through the tunnel about 500 feet above ford 

on and after April 26.

REGULATION. None.

ACCURACY. Stage-discharge relation fairly permanent except during floods. Rating 

curves used as follows: January 2-8 and 12-16, well defined; January 9-11, 17-19, 

and January 27 to March 29, fairly well defined; April 5 to June 24, well defined. 

Gage read to hundredths once daily; more frequent readings during high stages. 

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

except that for January 20-26, which was computed by shifting-control method, 

and March 30 to April 4, which was interpolated. Records good.

80 SURFACE WATEB SUPPLY, 1916, PART XI.

PACIFIC LIGHT & POWER CORPORATION'S CANAL NEAR AZUSA, CAL.

LOCATION. At Pacific Light & Power Corporation's power house, about 9 miles

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

County.

RECORDS AVAILABLE. 1896 to September 30, 1916. 

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

assumption that a discharge of one 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 OF DISCHARGE. 1896-1916: Maximum mean daily discharge recorded,

90 second-feet during most of period March 24 to August 3, 1915; no flow during

periods in 1901 and 1912. 

ACCURACY. Records good.

Diversion dam for canal is on San Gabriel River in the SE. J SE. £ sec. 31, T. 2 N., 

R. 9 W., about five 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, and after leaving the power plant, is divided and used 

for irrigation, being discharged into the Azusa-Covina canal and the rest into the 

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

wasted back into San Gabriel River below the gaging station.

Daily discharge, in second-feet, qf Pacific Light & Power Corporation's canal near 

Azusa, Cal.,for the year ending Sept. SO, 1916.

MONROVIA PIPE LINE NEAR MONROVIA, CAL.

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

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

RECORDS AVAILABLE. May 18 to September 30, 1916.

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

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

2.25 feet long; right weir, 2.26 feet long; crest of left weir at zero gage height; 

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

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

ACCURACY. Stage-discharge relation considered permanent, as conditions determining backwater for any stage are probably constant. Rating table considered 

accurate within 15 per cent up to 2.0 second-feet, within-10 per cent from 2.0 to 

3.0 second-feet, and within 5 per cent above. Gage read to hundredths twice a 

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

table. Records good.

The following current-meter measurement was made by J. C. Dort: 

May 19, 1916: Gage height, 0.49 foot; discharge, 5.1 second-feet.

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

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

driven into the sides of the canyon.

Daily discharge, in second-feet, of Monrovia pipe line near Monrovia, CaL, for the year

cabin; set in operation August 30, 1916.

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

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

stages; straight for 75 feet above control; right bank is rock cliff; left bank is 

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

small concrete dam, with triangular notch at left end, just below gage. Stage of 

zero flow, 0.70 foot; top of dam at stage 1.50 feet.

DIVERSIONS. None above.

REGULATION. None.

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

by measurments made during the year ending September 30, 1917. Mean daily 

gage heighf determined by inspection of water-stage recorder graph. Daily discharge ascertained by applying mean daily gage height to rating table. Records 

only roughly approximate, as discharge for rainy day, September 30, was 

estimated.

LOS ANGELES RIVER BASIN. 

LOS ANGELES RIVER AT LOS ANGELES, CAL.i

A measurement of l^os Angeles River was made at the bridge 

near the old pigeon farm above junction with Arroyo Seco. The 

discharge at 11 a. m. January 19, 1916, was 1,308 second-feet. The 

.maximum height of the flood during the storm was determined from 

an eye witness and from marks on the bank as 4 feet higher than 

the stage of the river at the time the measurement was made. A 

velocity of 11.0 feet per second was used for computing the probable 

maximum discharge. The estimated maximum flow for the stream 

at this point was 7,268 second-feet.
LOS ANGELES EIVEB BASIS'. 87

LOS ANGELES RIVER BETWEEN DOMINGUEZ JUNCTION AND CER&ITOS, CAL.

The following is a summary of measurements for January 18, 1916, 

for the flood flow between Dominguez Junction and Cerritos, of the 

the water entering the Los Angeles and Long Beach harbors: *

Second-feet. 

Main Cerritos bridge......................................... 22,873

Cota bridge (first opening to the west).......................... 1,816

At pole No. 1006 (second opening)............................ 676

Bridge No. 1463.............................................. 1,057

Bridge No. 1450.............................................. 978

Bridge No. 1433.............................................. 3,240

Bridge No. 1418............................................... 233

Compton Creek............................................... 240

31 113

As nearly as could be determined from the observations, practically 

half the above flow was going to the east into the Long Beach harbor 

and approximately half to the west into Wilmington harbor. It 

is considered that the flood of 1916 at this point was as great in 

volume as the flood in 1914 and that it lasted longer.

PACOIMA CREEK NEAR SAN FERNANDO, CAL.

LOCATION. In the SE. i NE. i sec. 24, T. 3 N., R. 15 W., about 800 feet above the

REGULATION . None.

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

defined. Gage read to hundredths once a day; sometimes oftener. Small amount 

of diurnal fluctuation at low water due to changes in temperature. Daily discharge ascertained by applying mean daily gage height to rating table. Record 

good but fragmentary.

ARROYO SECO AT LOS ANGELES,

On January 19, 1916, the flood flow of the Arroyo Seco was measured at Avenue 20 Bridge in Los Angeles. The peak of the flood had 

passed. Soundings were made from the bridge at intervals of 5 feet. 

The velocity was ascertained by means of floats and found to be 6.0 

feet per second. The ^discharge at 9.30 a. m., January 19, 1916, was 

737 second-feet. Prom the statement of an eyewitness and from 

water marks on the banks it was found that at the crest of the flood on 

the preceding days the water had been 4 feet higher than at the tune 

of measurement. Accordingly a section was computed for this 

higher level. The velocity at the higher stage was estimated -to be 

11.0 feet per second, .which gives a maximum discharge for the storm 

at this point of 6,215 second-feet.

SANTA CLARA RIVER BASIN. 

SESPE CREEK NEAR SESPE, CAL.

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

mile below mouth oi West Fork of Sespe Creek, 4£ miles above intake of Fillmore 

canal, and about 6$ miles northwest of Sespe, Ventura County.

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

RECORDS AVAILABLE. October 1, 1915, to March 11, 1916.

GAGE. Painted on large boulder 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. Bed composed of gravel and large boulders; fairly permanent.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 18.7 feet (time not 

given) January 17 (discharge 18,600 second-feet).

ACCURACY. Stage-discharge relation fairly permanent. The flood in January caused 

a slight scour in channel. Well-defined rating curves were used October 1 to 

January 17 and January 18 to March 11. Gage read to hundredths; number of 

readings a day not known. Daily discharge ascertained by applying gage k'eight, 

as reported, to rating table. Records good.

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

by Sespe Light & Power Co.

station.

DRAINAGE AREA. 218 square miles at site of station maintained previous to August 2, 

1916; measured on topographic map.

RECORDS AVAILABLE. November 1, 1903, to April 30, 1907; October 1, 1907, to January 31, 1908; February 6, 1910, to September 30, 1916. Station was maintained 

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

GAGE. Gage used previous to August 2, 1916, was staff in three sections about 900 

feet below north portal of the Santa Barbara water-supply tunnel; Friez waterstage recorder was.installed August 2 on left bank at portal of tunnel 50 feet above 

base of Gibraltar dam, but its records (except August 3-17) were not used because 

not properly tied in; record taken from outside staff gage attached to the well 

structure. Staff gages were read by employees of city of Santa Barbara. April 

13, old gage datum was lowered 5.00 feet.

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

sections. '

CHANNEL AND CONTROL. Bed composed of sand and gravel; shifts greatly during 

extremely high water; relatively permanent at low water. Control for new 

station is base of Gibraltar dam.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 16.3 feet at 4 a. m. 

January 18 (discharge, from extension of rating curve, about 4,200 second-feet); 

practically no flow September 9, 15, 16, 18, 22, 24, and 25.

1904-1916: 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. rCity of Santa Barbara diverts water at gage. The record at new site 

for this year includes the diversion. From August 8 to September 30, except from 

5 a. m. to 4 p. m. August 27, all the water in the river was being diverted.

REGULATION. None.

ACCURACY. Stage-discharge relation not permanent. Rating curve, December 24 to 

January 17, fairly well defined; January 18 to May 17, well defined below and 

extended above 800 second-feet; May 20 to July 28, well defined above 10 

second-feet and fairly well defined below; curves for August 2 to 3 and August

' 6 to September 30 are only roughly approximate. Gage read to hundre<Jths once 

or twice a day; mean daily gage heights August 3-17 determined by inspecting 

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

daily gage height to rating curve or table. Records good for medium stages but 

roughly approximate for high and low stages.

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

by city of Santa Barbara.

KERN RIVER BASIN.

KERN RIVER NEAR KERHVILLE, CAL.

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

County, in Kern National Forest, 3 miles above Salmon Creek and about 15 miles 

north of Kernville, Kern County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. January 1, 1912, to September 30, 1916.

GAGE. Friez water-stage recorder on left bank about a mile above mouth of Tobias 

Creek., Original gage was vertical staff in three sections fastened to overhanging 

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

14,1913, readings were taken from a temporary staff gage in two sections r. quarter 

mile upstream and were reduced to datum of original gage by a relation curve. 

The first gage was replaced March 17, 1914, by a vertical staff in fcwo sections, 7 

feet downstream from the original one, on the same bank and at the same datum. 

The recorder was installed September 15, 1913, in the same pool and at the same 

datum.

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

wading.

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

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

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

from water-stage recorder, 0.42 foot from 6.30 to 9 p. m., December 31 (discharge, 196 second-feet).

1912-1916: Maximum stage recorded, January 17,1916; minimum stage recorded, 

 0.75 foot January 6, 1913 (discharge, 142 second-feet).

DIVERSIONS. No information.

REGULATION. No information.

ACCURACY. Stage-discharge relation permanent since station was established. Rating 

curve well defined below and extended above 6,000 second-feet. Mean daily 

gage height obtained by an approximate method of integrating water-stage graph. 

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

or, for days of large range in stage, by averaging results obtained by applying 

mean stage of bihourly periods to rating table. Records excellent.

COOPERATION. Station maintained in cooperation with Southern California Edison 

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

TTJLABE LAKE BASIN. 

TULABE LAKE IS KINGS COUNTY, CAL.

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

Smith ranch, at quarter comer between sees. 8 and 17, T. 21 S., E. 20 E., about 5 

miles southwest of Stratford.

DRAINAGE ABBA. Not measured.

RECORDS AVAILABLE. March 15,1906, to September 30,1916 (incomplete). All published records give actual depth of water on the lowest point of the lake bed.

GAGE. Vertical staff in three sections; two are fastened to the headgate and highwater section is on levee near-by; read about once a week by Mrs. E .G. Kolbenstetter. Gage readings reduce to depth of water from the following data: Elevation of bottom of lake, 179.1 feet above mean sea level; elevation of zero of 

gage, 176.4 feet.

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

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

E; zero bf that gage was at elevation 175.1 feet. May 11, 1907, a staff gage was 

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

July 30, 1909. July 28, 1910, a vertical staff was installed on the section line 

just south of the comer to sees. 27, 28, 33 and 34, T. 20 S., R. 20 E., about 10 

miles south of Lemoore, near Stratford post office; elevation of the zero of this 

gage, 171.0 feet. 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., B. 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.

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

levees. The high water section was added July 16, 1916.
106 SURFACE WATER SUPPLY, 1916, PART XI.

EXTREMES OF STAGE. Maximum depth recorded during year, 11.3 feet July 4; 

minimum depth recorded, 0.0 foot November 21.

1906-1916: Maximum depth, 14.0 feet June 21, 1907; the lake was empty a 

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

and the last part of November, 1916.

COOPERATION. Most of the readings from February to July were furnished by Earnest 

 Coonradt.

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

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

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

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

the town of Corcoran, and the water surface about 12 feet below.

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

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

Depth, in feet, of Tulare Lake in Kings County, Cal.,for the year ending Sept. SO, 1916.

TULAEE LAKE BASES'. 113

EAWEAH RIVER NEAR THREE RIVERS, GAL.

LOCATION. In the SE. i sec. 27, T. 17 S., R. 28 E., at J. O. Carter's ranch 1J miles 

southwest of Three Rivers, Tulare County, South Fork enters three-fourths mile, 

and North Fork 3 miles above the station.

DRAINAGE AREA. 520 square miles.

RBSORDS AVAILABLE. April 29, 1903, to September 30, 1916. 

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. Bed composed of gravel and boulders; fairly permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 13.5 feet at 11 a. m.

January 17 (discharge from extension of rating curve, about 14,700 second-feet);

minimum stage recorded, 4.42 feet at 6 a. m October 29 (discharge, 38 second-feet).

1903-1916: Maximum stage recorded January 17,1916; minimum stage recorded,

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

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

above the station.

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

to be small.

ACCURACY. Stage-discharge relation for low water changed during flood of January 

17. Rating curve before flood, well defined between 75 and 4,000 second-feet; 

curve after flood well defined between 150 and 4,000 second-feet; curves merge 

at 1,470 second-feet; above 4,000 second-feet curve is an extension. Gage read 

to hundredths twice daily. Daily discharge ascertained by applying mean 

daily gage height to rating table. Records excellent except for extremely high 

and extremely low water, for which they are probably good.

LOCATION. In the SW. i sec. 2, T. 17 S., R. 28 E., at highway bridge in Sequoia 

National Forest, about half a mile north of Kaweah, Tulare County, and 2 miles 

above junction with Kaweah River. Manikin Creek enters one-fourth mile 

below and Sheep Creek 2£ miles above gage.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. October 12, 1910, to September 30,1916.

GAGE. Staff gage in two sections on right bank; low-water section is inclined and 

fastened to abutment of bridge; upper section is fastened vertically to sycamore 

tree, 20 feet below bridge. Previous to flood in January, 1914, gage was vertical 

staff fastened to right abutment. Original datum has been maintained. Gage 

read by J. T. Weckert.

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

CHANNEL AND CONTROL. Bed composed of solid rock and sand; fairly permanent. 

One channel at all stages.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 8.4 feet at 10 

a. m. January 17 (discharge, from extension of rating curve, about 5,380 secondfeet); minimum stage recorded, 0.59 foot at 1 p. m. October 1 (discharge, 1.4 

second-feet).

1910-1916: Maximum stage recorded, 10.2 feet at 7 p. m. January 25, 1914 

(discharge, from extension of rating curve, about 7,400 second-feet); minimum 

stage recorded 0.35 foot August 27, 1913 (discharge 0.8 second-foot). Lower 

, stages recorded gave larger discharges.

DIVERSIONS. About 20 second-feet is diverted by several small ditches for irrigation 

above the station.

REGULATION. None.

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

fairly well denned between 2 and 3,000 second-feet and extended above 3,000 

second-feet. Gage read to hundredths once daily. Daily discharge ascertained 

by applying gage height to rating table. Records good.

SAN JOAQUIN RIVER NEAR NEWMAN, CAL.

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

road, 300 feet below mouth of Merced River, and 3| miles northeast of Newman, 

Stanislaus County.

DRAINAGE AREA.-<-Not measured.

RECORDS AVAILABLE. April 29, 1912, to September 30, 1916.

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

60 feet below the bridge, in middle of stream. Gage read by Rasmus Lorensen.
122 SURFACE WATER SUPPLY, 1916, PART XI.

DISCHARGE MEASUREMENTS. Made from bridge or by wading.

CHANNEL AND CONTROL. Bed composed of sand and small gravel; shifts during high 

water. Banks subject to overflow.

EXTREMES OP DISCHARGE. Maximum stage recorded during 'year, 17 feet at 7 a. m. 

February 6 (discharge, 18,200 second-feet); minimum stage recorded, 1.85 feet 

at 7 a. m. October 28 (discharge, 122 second-feet).

1912-1916: Maximum stage recorded, 18 feet at 9 a. m. January 27, 1914 

(discharge, 20,700 second-feet); minimum stage recorded, 1.0 foot October 5 and 

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

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

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

water.

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

at Crane Valley reservoir on North Fork Creek.

ACCURACY. Stage-discharge relation for low water changed during the winter, probably January 5, when there was a sudden rise of almost 5 feet in stage. Rating 

curves before and after change fairly well denned and merge into one at discharge 

5,740 second-feet. Gage read to quarter tenths once daily. Daily discharge 

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

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

LOCATION. At about 75 feet below intake at Shaver Lake dam on Stevenson Creek,

at Shaver, Fresno County.

RECORDS AVAILABLE. November 13, 1915, to September 30, 1916. 

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

DISCHARGE MEASUREMENTS. The weir was rated by discharge measurements made

from bridge a short distance below it. 

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

rectangular weir with steel crest. 

ICE. Considerable ice forms in flume in winter. 

ACCURACY. Stage-discharge relation did not change and was not affected by ice.

Bating curve well defined. Mean daily gage height obtained by inspection of

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

gage height to rating table. Records probably excellent. 

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

The water is used for chuting lumber and upon reaching Clovis is used for irrigation.

1911-1914 and 1916: Maximum stage recorded, that of January 17, 1916; 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.

REGULATION. None.

ACCURACY. Stage-discharge relation was changed by flood of January 17. Rating 

curve before flood well defined between 25 and 200 second-feet and extended 

above; curve after flood well defined between 25 and 600 second-feet and extended above; curves are the same below 38 second-feet and common curve is 

extended below 15 second-feet. Gage read to quarter-tenths, usually once daily. 

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

Record excellent for medium stages and probably fair for extremely high and 

low water.

MERCED RIVER AT HAPPY ISLES BRIDGE, NEAR YOSEMITE, CAL.

LOCATION. At Happy Isles Bridge, at power house, about 1| miles southeast of

Yosemite, Mariposa County.

DBAINAGE AREA. 181 square miles (measured on topographic map). 

RECORDS AVAILABLE. August 23, 1915, to September 30, 1916. 

GAGE. Vertical staff fastened to downstream side of large boulder which is used for

right abutment of bridge. Gage read by Pettis and Jenkins. 

DISCHARGE MEASUREMENTS, Made from Clark Bridge about half a mile below gage

or by wading.
BAN JOAQUIN BIVEE BASIN. 129

CHANNEL AND CONTROL. Bed composed of boulders; probably permanent. Banks 

high; not subject to overflow. 

EXTREMES OP DISCHARGE. 1915-16: Maximum stage recorded, 6.2 feet at 8 a. m. 

June 7,10, and 17,1916 (discharge, 2,500 second-feet); minimum stage recorded, 

1.00 foot October 30 to November 8, 1915 (discharge, 5.5 second-feet).

ICE. Stage-discharge relation possibly slightly affected by ice.

DIVERSIONS. None.

REGULATION. Power plant above station; water returned to river just above gage.

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

read to hundredths twice daily. Daily discharge ascertained by applying 

mean daily gage height to rating table. Operation of power plant just above 

station causes diurnal fluctuation, especially during low stages. Melting of snow 

also results in considerable diurnal fluctuation. For these periods the mean 

daily gage heights, obtained from two readings of gage per day, are somewhat in 

error. Records good.

COOPERATION. Gage-height record furnished by National Park Service.

TUOLUMNE RIVER NEAR BUCK MEADOWS,! CAL.

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

Fork of Tuolumne River, and about 2 milea north of Buck Meadows, Mariposa 

County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. September 2, 1907, to September 30, 1916 (not complete).

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

2, 1913. Prior to January 2, 1913, station was maintained by the Yosemite Power 

Co. in the pool above, the gage consisting 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. Bed composed of boulders and solid rock; probably permanent. Banks high and not subject to overflow.

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

10.3 feet at 4.45 a. m. June 9 (discharge, 12,400 second-feet); minimum stage from 

water-stage recorder, 0.50 foot October 30 to November 2 (discharge, 36 secondfeet).

1907-1916: 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. At Harden ranch, 7 miles above the mouth of South Fork of Tuolumne 

River, a small amount of water is diverted for use in vicinity of Groveland.

REGULATION. None.

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

trouble with water-stage recorder caused breaks in record. Mean daily gage 

height found by averaging gage height recorded every 15 minutes. Daily discharge ascertained by applying mean daily gage height to rating table except 

for periods of no gage-height record for which discharge was estimated; (see 

footnote to daily-discharge table). Records excellent for periods during which 

recorder was running; fair for other periods.

SAN JOAQUIK RIVER BASIN. 147 

TTJOLUMNE RIVER NEAR LA GRANGE, CAL.

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

miles northeast of La Grange, Stanislaus County.

DRAINAGE AREA. 1,500 square miles.

RECORDS AVAILABLE. August 30, 1895, to September 30, 1916.

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 at wagon bridge at La Grange.

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

of water on crest of curbed 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. River bed is composed of gravel and boulders. Dam is 

a permanent control.

EXTREMES OF DISCHARGE. Maximum stage during year, 8.0 feet at 5 p. m. March 20 

(discharge, 20,500 second-feet); minimum stage, no flow over dam; see footnote 

to daily-discharge table.

1907-1916: 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) ; 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 irrigation.

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 combined record of river and canals is affected by seepage through dam 

and from canals, by the small amount of water that is occasionally spilled from 

canals at the waste gates above the gaging stations, and by the water discharged 

through the ports and sandgates in the dam during periods of the year. The 

records at the new station, 3$ miles above La Grange dam, are much more accurate, 

especially during low water. See record of combined flow of Tuolumne River 

above La Grange dam near La Grange, page 146. The following record is pub- 

 lished for Comparative purposes.

EVAPORATION FROM LAKE ELEANOR NEAR SEQUOIA, CAL.

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

12 miles north of Sequoia, Tuolumne County. 

RECORDS AVAILABLE. February 27, 1915, to September 30, 1916. 

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 made several times a week by an engineer who measures

the amount of water he adds to or takes out of 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.

Nunlber 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, Cal., 

for the year ending Sept. SO, 1916.

1914-1916: Maximum stage recorded, 8.0 feet at 7 a. m. and 5 p. m. January 25,

1914 (discharge determined from extension of rating curve, about 3,510 secondfeet); minimum stage recorded, 1.20 feet during periods in the falls of 1914 and

1915 (discharge, 8.7 second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS. None above the station.

REGULATION. None.

ACCURACY. Stage-discharge relation changed during high water January 17. Rating 

curve used before that date, well denned below 400 second-feet, Extended 

above; curve used after January 17 well denned between 50 and 400 second-feet; 

both curves the same above 160 second-feet. Gage read to tenths twice daily; 

during low water to half-tenths. Daily discharge ascertained by applying mean 

daily gage height to rating table. Records good except for discharge above 400 

second-feet and for periods during which gage was not read (see footnote to dailydischarge table) for which they are considered fair.

COOPERATION. Gage-height record furnished by Yosemite Power Co.

YOSEMITE POWER CO.'S CANAL NEAR LA GRANGE, GAL.

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

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

II miles northeast of La Grange, Stanislaus County; and about 13| miles below 

intake on Tuolumne River.

RECORDS AVAILABLE. 1908 to September 30, 1916 (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 OP DISCHARGE. 1910-1916: Maximum discharge recorded, 68 secondfeet most of summer of 1916; no flow during periods of every year. 

ACCURACY. Change in stage-discharge relation caused by cleaning of canal in early 

spring. Rating curve before and after change fairly well denned.. Gage read 

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

to rating table. Records good. 

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

R. V. Meikle, chief engineer.

The 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 locally 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 in the last part of 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 headworks 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: 

May 10, 1916: Gage height, 2.74 feet; discharge, 66 second-feet.

Daily discharge, in second-feet, of Yosemite Power Co.'s canal near La Grange, Cal.,

MODESTO CANAL NEAR LA GRANGE, CAL.

LOCATION. In the SE. J sec. 17, T. 3 S., R. 14 E., below waste gates and 460 feet 

below intake at La Grange dam on Tuolumne River, and about li miles northeast of La Grange, Stanislaus County. Canal is on right bank of river.

RECORDS AVAILABLE. April 26, 1903, to September 30, 1916.

GAGE. Vertical iron staff in concrete well on left bank, 460 feet below headgates 

and below waste gates. Gage read and operation of head gates noted by E. A. 

Townsend.

DISCHARGE MEASUREMENTS. Made from footbridge 550 feet below gage.

CHANNEL AND CONTROL. Canal is concrete lined and control is length of canal. For 

the last two years timber flumes that composed the canal a mile or more below 

the station have been gradually replaced by fills with concrete lining, and the 

cross-section was increased. The discharge per foot stage above 1.5 feet has 

been increased.

EXTREMES OP DISCHARGE. 1903-1916: Maximum stage recorded, 4.8 feet during 

most of summer of 1916 (discharge, 872 second-feet).

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

defined. Gage read to hundredth^ 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 to rating table gage heights for parts 

of day. Records excellent.

COOPERATION. Gage-height record furnished by Modesto irrigation district, through 

F. A. Townsend, patrolman.

The water is used for irrigation in the Modesto irrigation district.

SAtt JOAQUIK RIVER BASIN. 165

STANISLAUS RIVER NEAR KNIGHTS FERRY, CAL.

LOCATION. In the SW. J see. 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; 

replaces station at Knights Ferry, which was discontinued April 30, 1916.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. December 18, 1915, to Septemver 30, 1916.

GAGE. Gurley printing water-stage recorder on right bank in reinforced concrete well 

and house.

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

wading.

CHANNEL AND CONTROL. Bed composed of solid rock and shifting sand. One channel 

at all stages; straight for 250 feet above and 300 feet below gage. Control is Tulloch dam. Point of zero flow, gage height O.Q foot.

EXTREMES OP DISCHARGE. Maximum stage during period, from water-stage recorder, 7.9 feet at 5.45 p. m. March 20 (discharge determined from extension of 

rating curve, 14,200 second-feet); minimum stage from water-stage recorder, 

1.21 feet at 3 a. m. Sept. 8 and 16, and 6 a. m. September 10 (discharge, 146 

second-feet).

DIVERSIONS. Ditches diverting water for 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 Avery). 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 the drainage basins of the Middle Fork (see 

Relief Creek near Baker Station), North Fork, and South Fork.

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

10,000 second-feet and extended above. Operation of water-stage recorder not 

entirely satisfactory February 4 to March 5. Mean daily gage height ascertained 

by averaging readings printed every 15 minutes. Daily discharge ascertained 

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

is running properly. See footnote to daily-discharge table.

SAN JOAQUIN KIVEB BASIN. 167

STANISLAUS RIVER AT KNIGHTS FERRY, GAL.

LOCATION. In the NE. J sec. 29, T. 1 S., R. 12 E., at Knights Ferry, Stanislaus 

County, 12 miles northeast of Oakdale, and about 25 miles below mouth of South 

Pork.

DRAINAGE AREA. 935 square miles.

RECORDS AVAILABLE. May 19, 1903, to April 30, 1916, when the station was discontinued. This station was replaced by the one established near Knights Ferry, 

December 18, 1915. From May 3, 1895, to February 16,1901, a station was maintained half a mile north of Oakdale.

GAGE. Staff in five sections on right bank two vertical and three inclined; read by 

E. J. Coop. The original gage datum has been maintained, although several 

changes have been made in the gage. Zero of gage is 157.53 feet above sea level, 

United States Geological Survey datum.

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

CHANNEL AND CONTROL. Bed composed of small boulders and gravel; shifts slightly. 

One channel at all stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 14.3 feet at 5 p. m. 

March 20 (discharge, 15,600 second-feet); minimum stage recorded, 3.89 feet 

October 29 to November 4 (estimated discharge, 13 second-feet).

1903-1916: Maximum stage recorded, 26.0 feet at 4 a. m. January 31, 1911 (discharge, 60,000 second-feet); minimum stage, no flow December 3-5, 1912.

DIVERSIONS. The South San Joaquin canal 1 heads on the right bank and the Oakdale 

canal on the left bank at Goodwin dam, 4 miles above Knights Ferry (gaging 

stations are maintained on these canals near their intake). Some power is occasionally developed at Knights Ferry above the station. See also Stanislaus River 

near Knights Ferry, page 165.

REGULATION. See Stanislaus River near Knights Ferry.

ACCURACY. Stage-discharge relation changed January 18, February 5, March 5, and 

March 20. Rating curves covering periods between changes well defined. Gage 

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

mean daily gage height to rating table. Records good except October 6 to 

November 19, for which they are only roughly approximate, because the stagedischarge relation for extremely low water is affected by changes in control caused 

by fording of river at control.

The total flow of the river at this point is ascertained by combining the discharge 

at the river gaging station with the discharge of South San Joaquin and Oakdale canals.

TJTICA GOLD MUTING CO.'S CANAL NEAR AVERY, GAL.

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

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

RECORDS AVAILABLE. July 14, 1914, to September 30, 1916.

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

gage used previous to May 19, 1915, was vertical staff 300 feet above and on the 

right bank, so near the head gate that it could not be properly rated. Gage read 

by James Hunter.

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

CHANNEL AND CONTROL. Rectangular wooden flume.

EXTREMES OP DISCHARGE. 1914-1916: Maximum stage recorded, 1.65 eet May 19, 

1915 (discharge, 116 second-feet).

ICE. Stage-discharge relation may be affected by ice during extremely cold weather.

ACCURACY. Stage-discharge relation changed probably February 18; not affected by 

ice. Rating curves used before and after the change well defined. Gage read to 

half tenths once a day on alternate days except August and September, when 

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

rating table; interpolated for days on which gage was not read. Records good.

Record for October, 1915, does not wholly agree with that obtained on North 

Fork of Stanislaus River at Avery just above intake, when canal is taking all the 

water; discrepancy probably due to lack of refinement in reading gage heights.

COOPERATION. Gage-height record furnished by Utica Gold Mining Co.
174 SUEFAOB WATEE SUPPLY, 1916, PAET XI.

The following discharge measurements was made by Charles LeidI: 

July 8, 1916: Gage height, 1.10 feet; discharge, 62 second-feet.

Daily discharge, in second-feet, of Utica Gold Mining Co.'s canal near Avery, Cal., for the

year ending Sept. 30, 1916.

SAN JOAQTTIN RTVEE BASIN. 175

SOUTH FORK OF STANISLAUS RIVER AT STRAWBERRY,* CAI*

LOCATION. In the SE. £ 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, 1J miles below mouth of Herring Creek, and 15 miles 

northeast of Confidence.

DRAINAGE AREA. About 54 square miles.

RECORDS AVAILABLE. October 20, 1911, to September 30, 1916.

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

feet above suspension foot bridge. Gage read by an employee of the Sierra & 

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

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

October 10; old gage reinstalled October 14. Original datum has probably not 

been maintained.

DISCHARGE MEASUREMENTS. Made from suspension foot bridge or by wading.

CHANNEL AND CONTROL. Bed composed of gravel and boulders; apparently permanent. Left bank about 20 feet high; right bank lower but probably not subject 

to overflow.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 4.1 feet at 4 p. m. 

May 5 and 8 a. m. May 6 (discharge, 775 second-feet); minimum stage recorded, 

0.70 feet November 2-6 (discharge, 5.0 second-feet).

1911-1916: 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. Flow partly regulated by three reservoirs which have been constructed 

above the station to supply Tuolumne and Sonora with water for domestic use 

and for power development; 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.

Discharge measurements of South Fork of Stanislaus River at Strawberry, Cal., during

the year ending Sept. SO, 1916.

COSTTMNES RIVER AT MICHIGAN BAR, CAL.

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

Bar, Sacramento County, 5J miles southwest of Latrobe. The North and Middle 

Forks unite 12 miles above the station.

DRAINAGE AREA. 524 square miles.

RECORDS AVAILABLE. October 20, 1907, to September 30, 1916.

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. Bed composed of sand, gravel, and small boulders; fairly 

permanent. Zero flow occurs, gage height 1.4 feet ±0.1 foot.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 8.1 feet at 7 a. m. 

March 20 (discharge, 10,400 second-feet); minimum stage recorded, 1.98 feet 

August 27-30 and September 3-5 (discharge, 5.5 second-feet).

1907-1916: Maximum stage recorded, 10.9 feet January 31, 1911 (discharge, 

22,400 second-feet); no flow 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 water which is used 

for power development for domestic supply and irrigation 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 Gosumnes at 

Musicdale Creek. Record of amount of water diverted not available.-

REGULATION. Flow partly regulated by diversions.

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

\ 30 second-feet and fairly well defined below; same curve applicable, since 

February 1, 1911. Gage read to hundredths twice daily. Daily discharge ascer--, 

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

except for low water, for which they are good.
190 SURFACE WATEE SUPPLY, 1916, PAET XI.

The following discharge measurement was made by H. D. McGlashan: November 

20, 1915: Gage height, 2.48 feet; discharge, 37 second-feet.

SURFACE WATER SUPPLY, 1916, PART XI. 191

GOOSE LAKE BASIN. 

DREWS CREEK RESERVOIR HEAR LAKEVEEW, OREtt.

LOCATION. Dam is in sec. 5, T. 40 S., R. 18 E.; reservoir extends upstream about

10 miles. 

RECORDS AVAILABLE. February 26, 1913, to September 30, 1916; occasional readings

until February 6,1916; after that date readings practically every day. 

GAGE. Gage face attached to plank on upstream face of dam in 1915. Previous

readings obtained by measuring down from the floor of gage house. Gage heights

.refer to a datum level with lowest contour of reservoir. Gage reader, R. J.

Gilbert. 

OUTLETS. A tunnel with sill at elevation 16.3 feet and a blow-out pipe in center

of dam at bottom. 

REGULATION. Reservoir was filled up to outlet tunnel during winter of 1911-12

but was practically empty October 1, 1912. The rate of filling between that

date and March 31, 1913, has been estimated. 

EXTREMES OF STAGE. Maximum stage recorded during year, 41.1 feet March 21

(quantity stored, 18,000 acre-feet); minimum stage recorded, 17.8 feet January

15, 19 to 24 (quantity stored, 582 acre-feet). 

1913-1916: Maximum stage recorded, 53.4 feet April 18-20, 1914 (quantity

stored, 55,500 acre-feet). 

ACCURACY. Prior to 1914 the monthly estimates of increase or decrease of volume

of storage are only roughly approximate, as the readings of water stage are very

rough, but the error for the entire year is probably not great. Beginning in 1914

results are good.

The following readings, near the.end of each month, have been used in correcting 

the observed flow of Drews Creek below the dam:

DREWS CREEK HEAR LAKEVIEW, OREG.

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

below mouth of Willow Creek, a mile below the Drews Creek dam, and 18 miles 

southwest of Lakeview, Lake County.

DRAINAGE AREA. 211 square miles.

RECORDS AVAILABLE. January 16, 1909, to September 30, 1916.

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. 

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.
192 SURFACE WATEE SUPPLY,, 1916, PART XI.

DISCHARGE MEASUREMENTS. Made from wagon bridge or by wading.

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

and growth of aquatic plants may collect on control occasionally, affecting stagedischarge relation. At highest stages water flows into a second channel.

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

5.20 feet at 1.30 p. m. March 19 (discharge, 672 second-feet); minimum stage, 

from water-stage recorder, 1.72 feet January 29, 30 and February 2 (discharge, 

0.5 second-foot or less).

1909-1916: 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) evening of March 1-2, 1910 (discharge probably 

about 3,000 second-feet). Creek dry at times.

ICE. Stage-discharge relation affected by ice.

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

past the station; record is kept, its discharge is recorded and is added to determine 

the total run-off from the creek.

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 high-water period; not permanent 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 gage height graph, or, for 

days of considerable fluctuation, by subdividing days. Shifting-control method 

used for periods when stage-discharge relation was affected by weeds and ice. 

Records poor for September, fair October to January and June to August, and 

good February to May.

NOTE. Stage-discharge relation aflected by ice Dec. 13-18 and about Jan. 9 to Feb. 13; operation of 

gage prevented by ice Jan. 10-31; daily discharge estimated from current-meter measurements, observ. 

era' notes, and temperature records. Stage-discharge relation believed to be aflected by growth of 

aquatic plants Oct. 1 to Dec. 1 and May 10 to Sept. 30; daily discharge estimated from current-meter 

measurements and records of flow below dam which were furnished by Goose Late Valley Irrigation 

Co. Mean discharge, Nov. 1-9, estimated as 2.0 second-feet; Jan. 9-25, 4 second-feet; Jan. 26-31, 0.5

NORTH DREWS CANAL NEAR LAKEVIEW, OREG.

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

about 2 miles below the intake of the canal at the Drews Creek dam and onethird mile above a spillway, 18 miles southwest of Lakeview, Lake County.

RECOKDS AVAILABLE. March 18, 1914, to September 30, 1916.

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

gate of dam was also read during 1915. Gage read by R. J. Gilbert

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

CHANNEL AND CONTROL. 12-foot wooden flume.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 1.70 feet April 1 

(discharge, 71 second-feet).

1914-1916: Maximum discharge 102 second-feet (gage height, 2.10 feet on gage 

above weir) March 28, 1914. Canal dry at times.

ACCURACY. Stage-discharge relation changed during winter, when water was out of 

canal, and was affected by growth of aquatic plants during summer. Fairly well 

defined rating curves used October 1 to November 12 and March 17 to June 9. 

Shifting-control method used June 10 to September 30, based on study of records 

on a weir some distance below station. Gage read to hundredths about every 

other day. Daily discharge ascertained by applying daily gage height to rating 

table and by interpolation for days when gage was not read. Records good October to May, fair for June and poor July to September.

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

sec. 5 for irrigating land north of the creek on the west side of Goose Lake Valley.

SACRAMENTO BIVER BASIN. 201 

SACRAMENTO RIVER NEAR RED BLUFF, CAL.

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

miles northeast of Bed Bluff, Tehama County, and about 3 miles below the proposed Iron Canyon dam site. Paines Creek enters about 3 miles above and 

Antelope Creek about 7 miles below the 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 not 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 m'le 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 30,1916. The State engineer 

in 1879 and the commissioner of public works in 1893 and 1894 made measurements at this point. From April 30, 1895, to June 30, 1902, a gaginj. 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 

occasionally been used.

DISCHARGE MEASUREMENTS. Made from cable 50 feet above the gage.

CHANNEL AND CONTROL. Bed composed of coarse gravel and small boulders; practically permanent.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, ]9.4 feet at 9 a. m. 

February 11 (discharge, 101,000 second-feet); minimum stage recorded, 1.2 feet 

September 25-30 (discharge, 4,790 second-feet).

1902-1916: 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 storage of any importance has been developed in the drainage area 

above the station.

ACCURACY. Stage-discharge relation permanent except for slight variation'at low 

water, the maximum amount ot which is 5 per cent at the minimum recorded 

stage of 0.9 foot. Such a change probably occurred February 11. Rating curves 

well denned. Gage read to halt tenths twi- ce daily. Daily discharge ascertained 

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

DRAINAGE AREA. 5,260 square miles, not including the drainage area of Goose 

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

conMbuted no water except for a short time in 1869 and for not 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 secondfeet per square mile and run-off in depth in inches, based OB. the drainage area 

including Goose Lake, should be used with caution because of the large noncontributing area.

RECORDS AVAILABLE. Novembef 16, 1910, to September 30,1916.

GAGE. Vertical staff in two sections fastened to an ash tree on left bank 350 feet 

below ferry; read by M. D. Rodrigue. +

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

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 16.4 feet at 1.30 

p. m. February 10 (discharge from extension of rating curve, about 40,300 secondfeet); minimum stage recorded, 2.8 feet October 1-21 and August 4 to September 

30 (discharge, 2,740 second-feet).

1910-1916: Maximum stage recorded, 18.2 feet, December 31, 1913 (discharge, 

from extension of rating curve, about 47,000 second-feet); minimum stage recorded, 2.8 feet for long periods every year 1913-1916 (discharge, 2,740 secondfeet).

DIVERSIONS. A small amount of water is diverted from the main stream and tributaries, above the station, for irrigation.

REGULATION. None.

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

35,000 second-feet and extended above. Gage read to tenths once daily.

HAT GREEK AT HAT CREEK, CAL.

LOCATION. In the SE. $ sec. 10, T. 34 N., B. 4 E., at private highway bridge on 

Morris ranch, in Lassen National Forest, \1 mile north of Hat Creek post office, 

Shasta County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. September 22, 1910, to September 30,1916.

GAGE. Vertical staff fastened to downstream end of right abutment of bridge; original 

gage, which was at the same site, was carried out by mud flow from Lassen volcano 

in May, 1915; original datum lost. Gage read by Fred Seaborn.

DISCHARGE MEASUREMENTS. Made from downstream side of bridge.

CHANNEL AND CONTROL. Bed rough; composed of gravel and small boulders; shifts 

seldom; during summer months overgrown with aquatic plants.

EXTREMES OF STAGE. 1910-1916: Maximum stage recorded, 2.95 feet (original 

datum) at 3.55 p. m., May 17,1915; minimum stage recorded, 1.73 feet September 

11,1913 (discharge, 24 second-feet).

ICE. No information.

DIVERSIONS. On account of diversions for irrigation above station, this record does 

not show natural run-off from drainage basin. On May 13, 1911, nin- ditches 

were diverting a total of 110 second-feet. Of this amount it is estimated that 

55 second-feet were returned to stream above gage.

REGULATION. No information.

ACCURACY. Stage-discharge relation is affected by backwater from weeds during 

summer; the only two measurements that have been obtained for new gage indicate a shift in control; daily discharge not determined.

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

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

June 2,1916: Gage height, 1.62 feet; discharge, 128 second-feet.

SACRAMENTO RIVER BASIN". 215

FEATHER RIVER AT OROVILLE, CAL.

LOCATION. In sec. 8, T. 19 N., R. 4 E., at highway bridge at Oroville, Butte. County, 

6 miles below junction of North and Middle forks, and 30 miles above the mouth 

of Yuba River.

DRAINAGE AREA. 3,640 square miles.

RECORDS AVAILABLE. January 1, 1902, to September 30, 1916.

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 refer 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. The present water-stage 

recorder was put in operation December 16, 1912.

DISCHARGE MEASUREMENTS. Made from cable 1,000 feet above bridge. At extremely low water measurements have been made from a boat about 1,000 feet 

below the bridge.

CHANNEL AND CONTROL. Bed composed of boulders and gravel; shifts somewhat 

during high water.

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

11.8 feet from 1 to 9.30 a. m. March 20 (discharge, 58,300 second-feet); minimum 

stage from water-stage recorder, 0.60 foot from 7 to 8 p. m. October 31 (discharge, 

1,200 second-feet).

1902-1916: 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. None.

REGULATION. The operation of the Big Bend plant of the Great Western Power Co. 

causes diurnal fluctuation 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 until June, after which the substitute recorder tender made so many 

mistakes in setting instrument that the accuracy of record is somewhat doubtful. 

Mean daily gage height determined by an approximate method of integrating 

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

to rating table or, on days of wide range in stage, by averaging results obtained by 

applying to rating table mean gage height of bi-hourly intervals. Records 

excellent except possibly for July to September, when accuracy of stage record 

is somewhat doubtful.

SACEAMENTO EIVEE BASIN. 217

BUTT CREEK NEAR BUTTE VALLEY, CAL.

LOCATION. At lower end of Butte Valley, 100 feet below foot bridge, 1,000 feet above

intake to the Great Western Power Co. 's diversion flume, about one-fourth mile

south of Butte Valley post office, Plumas County, and 2 miles above junction

with North Fork of Feather River. 

DRAINAGE AREA. 75 square miles at original station. 

RECORDS AVAILABLE. June 14, 1905, to September 30, 1916. 

GAGE. Vertical staff on left bank, installed July 19, 1912, seven-eighths of a mile

upstream from original vertical staff which was on right bank. This gage is out

of the influence of the low-water diversion dam near the flume intake for the

Great Western Power Co. 's Butt Creek plant. 

DISCHARGE MEASUREMENTS. Made from footbridge at gage.

CHANNEL AND CONTROL. Bed composed of gravel and clay; practically permanent. 

EXTREMES OF DISCHARGE. 1905-1916: Maximum mean daily discharge, 1,640

second-feet January 16, 1909; minimum mean daily discharge, 21 second-feet

August 4 to 8, 1908. 

DIVERSIONS. The Oro Light & Power Co. diverts water through Wallack ditch from

Butt Creek above the station into the drainage basin of Yellow Creek; capacity

of ditch, 15 to 20 second-feet. 

ACCURACY. According to information received from the chief engineer of the

Great Western Power Co., the gage-height record, June 1 to August 1, 1911, is

unreliable. Records of discharge for this period, as published in Water-Supply

Paper 285, pages 284 and 285, should be discarded. 

COOPERATION. Daily-discharge record furnished by Great Western Power Co.,

through L. P. Cornell, engineer.

Daily discharge, in second-feet, of Butt Creek near Butte Valley, CaL, for the year

ending Sept. 30, 1916.

INDIAN CREEK NEAR CRESCENT MILLS, CAL.

LOCATION. In the SW. J sec. 25, T. 26 N., R. 9 E., at the lower end of Indian Valley, 

about 2,000 feet below Arlington Bridge, and 1J miles below Crescent Mills, 

Plumas County. Spanish Creek enters 4 miles below the station.

DRAINAGE AREA. 740 square miles.

RECORDS AVAILABLE. January 1, 1906, to December 31, 1909; September 10, 1911, 

to September 30, 1916.

GAGE. Vertical staff in three sections on right bank near observer's house, read by 

Eugene Cook. Same location and datum used throughout period of record, but 

lowest section was 0.46 foot too low from 1911 to August 12, 1915.

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

CHANNEL AND CONTROL. Bed composed of gravel and small boulders; fairly permanent. At low stages water is deep and sluggish at gage.

EXTREME OF DISCHARGE. Maximum stage recorded during year, 10.4 feet at 5 p. m.( 

March 20 (discharge, from extension of rating curve, about 7,040 second-feet); 

minimum stage recorded, 0.68 foot, October 1-4 (discharge, 34 second-feet).

1906-1916: Maximum stage recorded, 20.2 feet at 6.30 a. m., crest of flood of 

March 19, 1907 (discharge, from extension of rating curve, about 11,700 secondfeet); minimum stage recorded, 0.75 foot, August 9-15,1908 (discharge, 12 secondfeet).

DIVERSIONS. Water is diverted from Indian Creek for irrigation in Indian and 

Genesee Valleys.

REGULATION. None. ,

ACCURACY. Stage-discharge relation changed below discharge 280 second-feet, 

March 20; unchanged above this stage since station was established. Rating 

curve before change fairly well denned below 4,000 second-feet; after change 

fairly well defined between 75 and 4,000 second-feet. Gage read to hundredths 

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

table. Records good. '

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

September 30, 1916; rating curve used after March 20 was developed from measurements made subsequent to September 30.

changes in gage at that place were made, but all gages were on downstream side 

of log chute piers and original datum was maintained. -During construction of 

recorder well (Nov. 9 to Dec. 4) a staff gage at new site and new datum was read.

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

CHANNEL AND CONTROL. Bed composed of boulders and gravel; practically permanent. Left bank, flat and timbered; will be submerged at flood stages.

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

9.0 feet at 11.30 p. m. March 20 (discharge, 9,460 second-feet); minimum stage,

ACCURACY. Stage-discharge relation has not changed since station was relocated in 

1913; not affected by ice this year. Rating curve now well defined below 6,000 

second-feet but extended above. Mean daily gage height determined by averaging stage readings printed every 15 minutes. Daily discharge ascertained by 

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

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

June 9, 1916: Gage height, 4.46 feet; discharge, 878 second-feet.

SACRAMENTO EIVEB BASIN. 229

TUBA RIVES AT SMABTVILLE, CAL.

LOCATION. In sec. 22, T. 16 N., B. 6 E., at Narrows, 1 mile north of Smartville, 

Yuba County, 1 mile below mouth of Deer Creek, 6 J. 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, 1916.

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

On account of the gradual erosion of the channel, gage datum was lowered 10 

feet August 1, 1906. Before the change, first section was vertical and driven 

into gravel near left bank 50 feet below cable; second section was painted on rock 

ledge on left bank. , DISCHARGE MEASUREMENTS. Made from cable at gage.

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

high water. As the result of extensive hydraulic mining in the early days, the 

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

depth of mining d4bris is estimated to be more than 80 feet.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 13.6 feet at 2.15 

p. m. January 3 (discharge, 25,100 second-feet); minimum stage recorded, 2.45 

feet October 16 and 17 (discharge, 279 second-feet). Stage 2.1 feet latter part 

of summer gave discharge 300 second-feet.

1903-1916: Maximum stage recorded, 28.3 feet January 15, 1909 (discharge, 

111,000 second-feet); TnrmnniTn stage recorded, 3.23 feet October 5,1913 (discharge 

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

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

into the Bear River drainage basin.

ACCURACY. Stage-discharge relation changed January 3 and February 10 during 

high water. Rating curve used until January 3 poorly defined; curve used 

January 4 to February 10 fairly well defined; curve after February 10 well 

defined. Gage read to quarter tenths once daily. Daily discharge ascertained 

by applying gage height to rating table. Records up to first change in stage 

discharge relation fair; between changes good, and after-February 10 excellent.'

REGULATION. Small amount of storage has been developed above the station.

AccTJRACY.-^-Stage-diseharge relation changed some time between September 21 and 

November 22, and again between January 10 and 26; first change probably due 

to washing away of gravel bar November 9; second to high water January 25..

to January 25 fairly well defined below 3,000 second-feet and extended above; 

January 26 to September 30 well defined below 3,000 second-feet. Gage read 

usually to tenths tmce daily August, 1916, to May, 1916, and twice daily June 

to September, 1916. Daily discharge ascertained by applying mean daily gage 

height to rating table, Records fair to January 25 and good thereafter except 

for periods stated in footnote to daily-discharge table.

partly regulated by power plant at Folsom.

ACCURACY. Stage-discharge relation changed January 3 and 28 and about August 1, 

when sandbar interfered with operation of recorder. Rating curve October 1 to 

January 3 well denned between 70 and 600 and between 4,000 and 16,000 secondfeet and extended above; curve January 4-28 fairly well denned; curve January 

29 to August 1 well denned below 18,000 second-feet and extended above; curve 

August 24 to September 30 fairly well defined. Mean daily gage height determined by averaging readings printed every 15 minutes by recorder; temporary 

gage read twice daily' to half tenths, August 23 to September 30. Discharge 

August 2-23 obtained by shifting-control method; discharge for other periods 

ascertained by applying mean daily gage height to rating table or for periods in 

which recorder was not running, estimated from United States Weather Bureau 

gage heights at Folsom by means of a relation curve from readings on outside 

staff gage at Survey's station, by comparison with the records of flow for North, 

Middle, and South forks, or by interpolation. See footnote to daily discharge 

table. Records excellent when recorder was running previous to August 1; rest 

of record probably fair.

MIDDLE FORK OF AMERICAN RIVER NEAR EAST AUBURN, CAL.

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

about 1^ miles above the junction with North Fork of American River and 3^

miles northeast of East Auburn, Placer County. 

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. -October 22, 1911, to September 30, 1916. 

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 1 mile above gage or by wading. 

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

high water. .Banks high and not Subject to overflow.
248 SURFACE SUPPLY, 1916, PABT xi.

EXTREMES OF DISCHARGE. Maximum stage during year, 13.7 feet at 12 m. March 20 

(discharge from extension of rating curve, about 17,100 second-feet); minimum 

stage recorded, 1.0 foot at 7 a. m. October 23, 24, and 31 (discharge, 32 second-feet). 

1911-1916: Maximum stage recorded, 18.0 feet at 7 a. m. January 1, 1914 (discharge, from extension of rating curve, about 26,400 second-feet); minimum stage 

recorded. October 23, 24, and 31, 1915.

DIVERSIONS. Little South Fork ditch diverts from Gerle Creek and discharges into 

Pilot Creek drainage basin. Pilot Creek ditch diverts from Pilot Creek for irrigation on Georgetown divide. The 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 flood of March 20. Rating curve 

before change fairly well defined between 60 and 7,000 second-feet; after change 

well defined below 7,000 second-feset; curves merge into one above 2,200 secondfeet; extended above 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.

entire flow of the South Fork of American River is diverted for power; occasionally the quantity is insufficient and additional water is purchased from the Sierra 

Water Supply Co. The water diverted for power is returned to the river above 

the gaging station.

REGULATION. Echo and Silver lakes are used as storage reservoirs.

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

5,000 second-feet and extended above. Gage read to hundredths once daily. 

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

excellent.

The follo'wing discharge measurement was made by H. D. McGlashan: 

November 20,1915: Gage height, 3.90 feet; discharge, 135 second-feet.

PUTAH CREEK BASIN. 

PUTAH CREEK AT WINTERS, GAL.

LOCATION. Just below Southern Pacific Co. 's railroad bridge at Winters, Yolo County, 

in the Rfo de los Putos grant.

DRAINAGE ABBA. 805 square miles.

RECORDS AVAILABLE. September 26, 1905, to September 30, 1916.

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. Original datum 

has been maintained.

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

CHANNEL AND CONTROL. Bed composed of 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, 35.0 feet at 10 a. m. 

January 3 (discharge, from extension of rating curve, about 53,300 second-feet); 

minimum stage recorded, 4.75 feet October 5-9 (discharge, 6.5 second-feet).

1905-1916: 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 part of the years ending September 30, 1913 and 1914.

DIVERSION. Several small ditches and water for irrigation above station.

REGULATION. None.

ACCURACY. Stage-discharge relation for low water changed during flood of January 3. 

Low-water curves before and after change well defined; rating curve for left-bank 

gage well defined between 3,000 and 18,000 second-feet and extended above. 

Gage read to quarter tenths once daily. Daily discharge ascertained by applying 

gage height to rating table. Records good.

KLAMATH RIVER BASIN.

WILLIAMSON RIVER AT CHILOQTTOT, OREQ.

LOCATION. In the NW. i sec. 3, T. 35 S., R. 7 E.j at highway bridge about 500 fee,t 

above mouth of Sprague River and half a mile southwest of Chiloquin, Klamath 

County.

DRAINAGE AREA. 1,260 square miles.

RECORDS AVAILABLE. July 25, 1911, to September 30, 1916.

GAGE. Vertical staff on upstream side of right abutment of wagon bridge, except 

March 29 to July 16, 1915, when a temporary gage on downstream side of abutment was used. Gage read by TJ. S. Indian Service employees.

DISCHARGE MEASUREMENTS. Made from upstream side of wagon bridge; measuring 

conditions poor on account of rough bottom and uneven velocities.

CHANNEL AND CONTROL. Bed composed of rocks and gravel; shifts slightly. A 

second channel to the left of the main channel always carries some water; banks 

low and subject to overflow at extremely high stages.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 5.4 feet March 31 

to April 2 (discharge, 1,520 second-feet); minimum stage recorded, 3.83 feet 

October 4, 7, and 10 (discharge, 392 second-feet).

1911-1916: Maximum stage recorded, 6.6 feet April 16, 1913 (discharge, 2,520 

second-feet); minimum stage recorded, 3.80 feet August and September, 1915 

(discharge, 370 second-feet).

ICE .-^-Stage-discharge relation unaffected by ice as most of the water comes from 

springs.

DIVERSIONS. Practically none.

REGULATION . None.

ACCURACY. Stage-discharge relation changed April 1. Rating curves fairly well 

defined and applicable October 1 to March 31 and April 1 to September 30. Gage 

read to hundredths on days for which discharge is given in table of daily discharge. Daily discharge ascertained by applying daily gage height to rating 

table. Records good except those for January, May, July, and September, which 

are only fair on account of fragmentary gage-height record.

COOPERATION. Field data furnished by United Statea Indian Office, H. W. Hincks, 

assistant engineer.

258 SURFACE WATER SUPPLY, 1916, PART XI.

UPPER KLAMATH LAKE NEAR KLAMATH FALLS, OREQ.

LOCATION. In sec. 30, T. 38 S., R. 9 E., at the outlet of Upper Klam^ Lake, about

2 miles northwest of Klamath Palls, Klamath County. 

RECORDS AVAILABLE. May 28 to October 22, 1904; January 7, 1906, to September

30, 1916. 

GAGE. Friez water-stage recorder since February 16, 1906; vertical staff prior to

that date. Zero of gage is 4,136.13 feet above sea level. During 1904, gage

was a vertical staff on Pelican Bay, zero of which was 4,135.997 feet above sea

level. 1 Observer, Graham Keihl. 

EXTREMES OF STAGE. Maximum stage during year from water-stage recorder, 6.52

feet at 7 p. m. April 18; minimum etage from water-stage recorder, 3.65 feet

at 3 a. m., September 20. 

1904 and 1906-1916: Highest water ever known, determined from high-water

marks, 7.2 feet on Pelican Bay gage, about April 20, 1904, or 4,145.1 above sea

level. Minimum stage is probably that of 1916. 

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

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

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

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

COOPERATION. Since May, 1909, this station has been maintained by the United

States Reclamation Service.

KLAMATH BTVEB BASIN. 259 

LINK RIVER AT KLAMATH FALLS, OREO.

LOCATION. In the NW. i sec. 32, T. 38 S., R. 9 E., at county bridge over Link 

River, at Klamath Falls, Klamath County, If miles below the outlet of Upper 

Klamath Lake, and immediately above the head of Lake Ewanna.

DRAINAGE AREA. 3,110 square miles.

RECORDS AVAUABLE. May 15, 1904, to September 30, 1916.

GAGE. Friez water-stage recorder on left bank, about 500 yards above bridge in 

NW. \ sec. 32; elevation of zero is 4080.0 feet above sea level. Friez recorder 

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

30, 1912. A chain gage on the bridge has been read daily since 1904, and has 

been used for obtaining the discharge for periods when gage heights are not 

available for the other gage. Observer, Myrtle Ess.

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 the gage is evidently permanent and water from the tailrace of 

the, 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, 

7.41 feet at 10 p. m. April 10 (discharge, 4,170 second-feet); minimum stage 

during year 4.72 feet at 7 p. m. August 8 (discharge, 640 second-feet).

1904-1916: 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 secondfeet). 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 277. 

Some water is also diverted for irrigation from the tributaries to Upper Klamath 

Lake, but the total run-off is as yet practically unaffected.

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 Upper 

Klamath Lake.

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

denned between 800 and 4,000 second-feet. Operation of water-stage recorder 

satisfactory except lor short periods when clock was not running. Daily discharge 

October 1-15 and July 22 to September 30 ascertained by use of discharge integrator except for days when discharge was interpolated. Discharge for rest of 

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

determined by inspecting gage-height graph. Records excellent, except those for 

September, which are good.

COOPERATION. Most of field data furnished by United States Reclamation Service, 

J. G. Camp, project manager.

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, 1916. Records at Keno, 

May 31, 1904, to December 31, 1913, gave 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; 

read by Bertha Spencer.

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

at low water. 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 

stage. The upstream end 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. Bed composed of heavy gravel and boulders; practically 

permanent and very even.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 1.78 feet April 1 

(discharge, 3,810 second-feet); minimum stage recorded, 0.08 foot October 9 

(discharge, 850 second-feet).

1904-1916: Maximum stage recorded at Keno, 15.3 feet about May 10, 1904, 

from high-water marks observed May 31 (discharge, 9j250 second^feet); minimum 

stage at Keno, 11.5 feet October 2, 1908 (discharge, 730 second-feet). Stagedischarge relation varied considerably at the Keno station. The lowest discharge 

obtained as the result of a measurement was 680 second-feet (stage, 12 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. (See 

p. 279.)

REGULATION. None.
262 SURFACE WATER SUPPLY, 1916, PART XI.

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

denned. Gage read to hundredths three times a week. Daily discharge ascertained by applying daily gage height 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. G. 

Camp, project manager, KLamath project.

SPRAGUE RIVER NEAR YAINAX, OREG.

LOCATION. In the NW. I sec. 20, T. 36 S., R. 13 E., about 2 miles above the highway bridge on the road from Yainax to Silver Lake, about 4 miles above mouth 

of Sycan River, and about 10 miles east of Yainax, Klamath County.

DRAINAGE AREA. 513 square miles.

RECORDS AVAILABLE. April 19, 1912, to September 30, 1916.

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. 

Observers, engineers of United States Indian Service.

DISCHARGE MEASUREMENTS. Made from cable 100 feet below gage.

CHANNEL AND CONTROL. Bed composed of sand and gravel; no denned control, as 

stream is very sluggish for miles above and below gage; banks subject to overflow at a stage of about 5 feet and considerable water may flow in a cut-off across 

a bend to the right of the station.

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

4.50 feet at 8 p. m. March 21 (discharge, 825 second-feet). Recorder indicated a 

maximum of 5.3 feet between December 16 and February 16 (discharge, 1,070 

second-feet); also a minimum of 0.6 foot (discharge, 100 second-feet). Both 

records are somewhat doubtful.

1912-1916: Maximum stage recorded, 5.41 feet April 17, 1914 (discharge, 961 

second-feet). There was recorded at a station 2 miles downstream, on May 21, 

1904, a discharge of 2,080 second-feet. Minimum stage, that for 1916.

I&E. Stage-discharge relation seldom affected by ice, as stream is spring fed.

DIVERSIONS. Considerable water is diverted near Ely for inagation.

REGULATION. None.

ACCURACY. Stage-discharge relation changed during the year. Two fairly welldefined rating curves used, applicable as follows: February 16 to April 28, and 

May 30 to September 30; discharge April 29 to May 29 computed by method 

for shifting control. Records fair after February 15 except those for June and 

July, which are roughly approximate.

COOPERATION. Field data furnished by United States Indian Irrigation Service, 

H. W. Hincks, assistant engineer.

268 SURFACE WATER SUPPLY, 1916, PART XL

SPRAGUE RIVER AT CHILOQUIXT, OREG.

LOCATION. In the NE. J sec. 3, T. 35 S., R. 7 E., at wagon bridge half a mile above 

mouth and the same distance above the Southern Pacific Kailroad bridge, where 

the 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, 1916.

GAGE. Vertical staff on downstream end of first bridge pier from right bank; read 

once daily by employees of United States Indian Service. Chain gage on the 

railroad bridge was used 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. There may be slight effect from growth of aquatic plants at low 

water.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 3.95 feet March 24 

(discharge, 2,750 second-feet). Minimum discharge, 307 second-feet October 4 

(.gage height, 0.49 foot); no water in Modoc Point canal.

1911-1916:. Maximum stage recorded, 4.0 feet on gage at railroad bridge April 

16, 1913 (discharge, 3,350 second-feet); minimum 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 record was kept. A considerable quantity of water 

is also diverted for irrigation on 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 changed during winter (date assumed as February 13). Rating curves well defined. Gage read to hundredths for days for 

which discharge has been published. Daily discharge ascertained by applying 

gage height to rating table. Records good except those for January, February, 

and from June to September, which are only fair on account of infrequent gage

NOTE. For station on Modoc Point canal see page 272.

. SYCAN RIVER NEAR YAINAX, OREGt.

LOCATION. In the NW. J sec. 28, T. 35 S., R. 12 E., about 5 miles by river above 

mouth, and about 16 miles northeast of Yainax, Klamath County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. November 25, 1911, to September 30, 1916.

GAGE. Stevens water-stage recorder on left bank. Observers, engineers of United 

States Indian Office. 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 downstream 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 high-water marks 

(float of gage stuck), 9.7 feet March 21 (discharge, 1 ?720 second-feet); minimum 

stage from water-stage recorder, 0.37 foot February 5 and 6 (discharge, 30 secondfeet); early in October discharge estimated as 21 second-feet (stage-discharge 

relation affected by growth of aquatic plants).

1911-1916: Maximum discharge ascertained was that of 1916, but this may have 

been exceeded after washing out of old gage on April 13, 1913, after indicating 

a gage height corresponding to a discharge of 1,680 second-feet. Minimum discharge, 20 second-feet (gage-height, 0.71 foot) September 30, 1915 (stage-discharge 

relation affected by growth of aqtiatic plants).

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 in Sycan Marsh.

REGULATION . None.

ACCURACY. Stage-discharge relation changed during spring flood; fairly well-defined 

rating curves applicable November 20 to March 20, and March 21 to September 30. 

Operation of water-stage recorder satisfactory except that record indicates that 

intake pipe was partly silted up at times. Daily discharge ascertained by 

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

gage-height graph. Records good except for October, November, August, and 

September, for which months they are fair.

272 SURFACE WATER SUPPLY, 1916, TART XI.

MODOC POINT CANAL NEAR CHILOQTTIN, ORES.

LOCATION. In the SE. J sec. 3, T. 35 S., E. 7 E., at intake about a mile south of 

Chiloquin, Klamath County.

RECORDS AVAILABLE. June 14, 1915, to September 30, 1916.

GAGE. Inclined staff painted on left side of concrete-lined section, about 100 feet 

below head gates; installed June 29, 1915; previous to that date and from April 

21 to June 13, 1916, readings were made on gage at bridge, one-half mile below.

DISCHARGE MEASUREMENTS. Made by wading.

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 affect stage-discharge relation at 

intake, but did have a material effect on the gage at the bridge.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 1.65 feet June 21 

(discharge, 21 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 fairly permanent for gage at intake. Eating 

curve fairly well defined. Gage read to half tenths when station is visited. 

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

good for days when gage was read.

COOPERATION. Field data furnished by United States Indian Office, H. W. Hincks, 

project engineer.

KLAMATH RIVER BASIN. 273

WOOD RIVER AT FORT EXAMATH, OREG.

LOCATION. In sec. 22, T. 33 S., R. 7J E., at a highway bridge one-fourth mile east

of Fort Klamath, Klamath County. 

DRAINAGE AREA. -Not measured.

RECORDS AVAILABLE. August 5,1911, to September 30, 1916. 

GAGE. Vertical staff attached to bridge; read daily 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 OP DISCHARGE. Maximum stage of unobstructed flow recorded during

year, 1.95 feet March 19 (discharge, 370 second-feet); minimum stage recorded,

1.30 feet November 8 to 16 (discharge, 220 second-feet).

1911 and 1913-1916: 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 fairly permanent, except May 2 to July 28,

September 12-23 and 25-28, when it was affected by logs lodged below gage.

Rating curve for open-channel period fairly well defined. Gage read once daily

to half tenths; some readings appear questionable. Daily discharge ascertained

by applying daily gage height to the rating table. Records poor. 

COOPERATION. Gage-height records and part of discharge measurements furnished

by United States Reclamation Service.

FOURMILE CREEK NEAR ODESSA, OREG.

LOCATION. In the NW. \ sec. 9, T. 36 S., R. 5 E., just below the outlet of Fourmile

Lake, about 15 miles northwest of Odessa, Klamath County. 

DRAINAGE AREA. Not measured. 

RECORDS AVAILABLE. April 6, 1912, to September 30, 1916.
KLAMATH KIVER BASIN. 275

GAGE. Stevens water-stage recorder about 500 feet below outlet of lake since October. 

23, 1914, to replace Barrett & Lawrence recorder used since October 18, 1912. 

Vertical staff 10 feet below dam was used April 6 to August 8,1912. Observer, 

Geo. H. Frey.

DISCHARGE MEASUREMENTS. Made from a footbridge near gage or by wading.

CHANNEL AND CONTROL. Bed composed of heavy, angular boulders; may shift 

slightly.

EXTREMES OP DISCHARGE. Maximum stage recorded during year, 1.90 feet June 17 

to 20 (discharge, 50 second-feet); creek dry at times.

1912-1916: Maximum stage recorded, 2.5 feet about June 8, 1912, on old gage, 

estimated June 11 from high-water marks (discharge, 99 second-feet).

WINTER FLOW. Stage-discharge relation probably not affected by ice.

DIVERSIONS. None.

REGULATION. None; storage dam has never been operated.

ACCURACY. Stage-discharge relation for high stages changed slightly in 1916; practically permanent for low stages. Eating curve fairly well defined. Operation 

of water-stage recorder satisfactory after January 21. Daily discharge ascertained 

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

gage-height graph. Records fair for periods in which water-stage recorder was 

in operation.

A CANAL AT KLAMATH FALLS, OREG.

LOCATION. In the NW. J sec. 29, T. 38 S., R. 9 E., at the head of a tunnel about 

one-fourth mile below the head gates of the canal and about a mile northwest of 

Klamath Falls, Klamath County.

RECORDS AVAILABLE. Irrigation season, 1911 to 1916. Some water was diverted 

for three or four years prior to 1911, but no record was kept.

GAGE. Barrett & Lawrence water-stage recorder on right of canal just above weir.
KLAMATH RIVER BASItt. 277

DISCHARGE MEASUREMENTS. Made from a foot plank just inside lower end of tunnel, 

about one-half mile below gage; rectangular section, 13.5 feet wide.

CHANNEL AND CONTROL. Trapezoidal weir, 18.15 feet long, with, its crest 7,27 feet 

above bottom of canal, which is a concrete-lined section 13.5 feet wide qn the 

bottom, 12 feet deep, and with side slopes J to 1.

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

3.31 feet at noon June 21 (discharge, 377 second-feet).

191H916, maximum stage from recorder 3.4 feet June 25, 1915 (discharge, 392 

second-feet). Minimum discharge, zero.

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

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

inspection of gage-height graph. Records excellent except for March and September, for which months they are good.

COOPERATION. Data furnished by United States Reclamation Service.

This canal diverts water from Link River immediately below outlet of Upper 

Klamath Lake, in the NE. J sec. 30, T. 38 S., R. 9 E., for irrigating lands east of Klamath 

River on both sides of Lost River. Most of the return waters reach Lost River.

278 SURFACE WATER SUPPLY, 1916, PART XI.

LOST RIVER ABOVE OLENE, OREGK

LOCATION. In the NW. J sec. 21, T. 39 S., R. 11J E., at an old ford on Brotherton 

rai>ch in Poe Valley, about 5 miles east of Olene, Klamath County.

DRAINAGE AREA. Not measured.

RECORDS AVAILABLE. June 22 to September 30, 1915; May 5 to September 30,1916. 

The discharge does not differ materially from that recorded at the station at 

Olene, 1907 to 1912.

GAGE. Vertical staff on right bank 20 feet upstream from gage used in 1915; relation 

of gage datum not determined. Gage" read by United States Reclamation Service 

employees.

DISCHARGE MEASUREMENTS. Made by wading; section rather poor.

CHANNEL AND CONTROL. Bed composed of rock; control fairly permanent, but has 

only slight fall; overhanging willows and growth of aquatic plants may affect 

stage-discharge relation somewhat.

EXTREMES OF DISCHARGE. Maximum stage recorded during irrigating season, 1.53 

feet May 11' (discharge, 112 second-feet). Minimum stage recorded, 0.66 foot 

June 10 (discharge, 52 second-feet). For maximum and minimum, 1904 to 1915, 

see "Lost River at Wilson Bridge," page .

DIVERSIONS. Some land is irrigated in Yonna Valley, a few miles above the station, 

and a large area by flooding in Langell Valley. The low minimum in June is 

caused by diversions.

REGULATION. None.

ACCURACY. Stage-discharge relation permanent to about July 23; affected by growth 

of aquatic plants thereafter. Rating curve for period May 5 to July 23 well 

defined ^between 50 and 80 second-feet. Shifting-control method used July 24 

to August 31. Gage read once a day to hundredths. Daily discharge ascertained by applying daily gage height to rating table. Records good May to 

August. No discharge can be computed for September.

COOPERATION. Records furnished by United States Reclamation Service.

LOST RIVER AT WILSON BRIDGE, NEAR OLENE, OREG.

LOCATION. On line between sees. 29 and 30, T. 39 S., R. 10 E., at Wilson Bridge, 

about one-fourth mile below the diversion dam, and about 4 miles by river below 

Olene, Klamath County.

RECORDS AVAILABLE. March 14, 1912, to September 30, 1916.

DRAINAGE AREA. Not measured.

GAGE. Vertical staff attached to highway bridge. Zero of gage is 4,005.18 feet above 

sea level and 60 feet below datum used in 1912. Gage read by the watchman for 

the dam.

DISCHARGE MEASUREMENTS. Made from highway bridge or by wading.

CHANNEL AND CONTROL. Bed composed of gravel and chalk rock; clean and fairly 

permanent.

EXTREMES OF DISCHARGE. Maximum stage recorded during year, 65.1 feet at 10 a. m. 

March 21 (discharge, 850 second-feet); channel practically dry except when total 

discharge of river exceeds capacity of diversion canal.

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 conditions, 4.29 feet June 19, 

1911, at Olene (discharge, 58 second-feet).

ICE. Stage-discharge relation not affected by ice.

DIVERSIONS.- -This station is just below the dam at which practically all the discharge 

of Lost River up to about 500 second-feet is diverted through the diversion canal 

into Klamath River or into the "G" canal (formerly Griffith lateral) 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 practically permanent. Rating curve fairly well 

defined. Gage read to hundredths twice daily while water was running. Daily 

discharge ascertained by applying daily gage height to rating table. Record good.

COOPERATION. Field data furnished by United States Reclamation Service.

LOST RIVER NEAR MERRILL, OREG.

LOCATION. In the SE. i sec. 34, T. 30 S., R. 10 E., 200 feet above wagon bridge near

the Adams flume of C canal, a mile north and a mile west of Merrill, Klamath.

County.

DRAINAGE. Not measured. 

RECORDS AVAILABLE. April 7 to September 30,1916. Records at old station 4 miles

northwest of Merrill, July 26, 1904, to February 28, 1909, not comparable with

those taken at station used in 1916.
KLAMATH RIVER BASIN. 281

GAGE. Gurley 7-day water-stage recorder on left bank; attended by employees of 

United States Keclamation Service.

DISCHAHGB MEASUREMENTS. Made by wading 20 feet below gage; favorable 

conditions.

CHANNEL AND CONTROL. Bed composed of chalk rock with tendency to cut. No 

x vegetation.

EXTREMES OF DISCHARGE. Maximum stage recorded April 1 to September 30, 1916, 

1.56 feet June 30 (discharge, 71 second-feet); minimum stage recorded, 0.60 foot 

April 20 (discharge, 13 second-feet).

ICE. No records during the winter months.

DIVERSIONS. All the natural flow of the river diverted at the Lost River dam, 6 

miles above, during the period covered by records. Discharge past station is 

entirely from return waters from lands under Klamath project and a little leakage 

through Lost River dam. No diversions below station.but water can be used for 

irrigating the reclaimed bed of Tule Lake if found suitable for irrigation purposes.

ACCURACY. Stage-discharge relation shifting until about July 10 (shifting-control 

method used); practically permanent thereafter (rating curve well defined between 25 and 50 second-feet). Daily discharge ascertained by applying to rating 

table the mean gage height obtained by inspecting recorder graph. Records 

good.

TULE LAKE NEAR MERRILL, OREG.

LOCATION. In sec. 8, T. 41 S., R. 11 E., at J. F. Adam's ranch near the mouth of

Lost River, 3 miles east of Merrill, Klamath County. 

RECORDS AVAILABLE. May 17, 1904, to September 30, 1916.

GAGE. Vertical staff fastened to boathouse on shore of lake, July 26, 1912, to May 

17, 1915, when a new gage was installed about 300 feet farther upstream. Datum 

lowered May 17, 1915, and September 22, 1916. All published gage heights 

beginning October 1, 1913, refer to a datum 4,000 feet above sea level; these given 

in Water-Supply Paper 361, page 450, refer to a datum 4,050 feet above sea level. 

A vertical staff on a post driven in the lake bed had been used up to July, 1912. 

The elevation of its zero as determined from the best available information has 

been as follows:

Feet. 

May 17, 1904. ......................................... 4,047.73

October 21, 1904........................................ 4,047.76

May 11, 1907.......................................... 4,048.56

June 11, 1907 .......................................... 4, 048. 56

November27, 1908.....................................1 4,048. 60

The gage readings made from 1904 to 1913 have been published as reported, and 

no attempt has been made to reduce them to a uniform datum. A graph of the 

gage heights has failed to reveal any critical points that would account for a 

sudden change. It is therefore likely that the gage was raised by the ice a little 

at a time during the winters of 1905-6 and 1906-7. On account of this error the 

gage heights prior to May, 1907, should not be used for any refined studies.

EXTREMES OP STAGE. Maximum stage recorded 1904-1916, 11.35 feet April 30 and 

May 1, 1907, or 4,059.91 feet above sea level. Minimum stage recorded, 4,045.69 

feet, September 25, 1916.

DIVERSIONS AND REGULATION. In June, 1909, the Clear Lake dam was closed, and 

water has since been released from the reservoir only for short periods. Since 

May 1, 1912, most of the discharge of Lost River up to about 500 second-feet has 

been diverted at the Lost River dam into Klamath River. Tule Lake has therefore been falling rapidly since 1909.

COOPERATION. Since May, 1909, this station has been maintained by the United 

States Reclamation Service.

> Referred to the original bench mark installed in 1904. According to another bench mark it was at 

elevation 4,048.40.

MILLER CREEK NEAR LORELLA, OREG.

LOCATION. In sec. 7, T. 40 S., R. 14 E., at the site of an old wagon bridge, about

three-fourths mile above the highway bridge, 1 mile east of the Swingle ranch in

Langell Valley, and 3 miles south of Lorella, Klamath County. 

DRAINAGE AEEA. 270 square miles. 

RECORDS AVAILABLE. April 1, 1909, to September 30, 1916; 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.

GAGE. Friez water-stage recorder on left bank attached to old bridge abutment. 

DISCHARGE MEASUREMENTS. Made from highway bridge, or by wading at low water;

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

7.21 feet at 3 a. m. March 17 (discharge, 1,490 second-feet); minimum stage from

water-stage recorder, 2.39 feet August 26 (creek probably dry or nearly so).

1904-1916, maximum stage recorded, 14.0 feet, February 5, 1907 (discharge

6,730 second-feet). 

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 no discharge records have been computed for'low winter stages in

1915 and 1916. 

DIVERSIONS. A small irrigating flume, carrying about 1 second-foot, diverts just

above the present station, and probably a considerable area is irrigated above

the station.
284 SURFACE WATER SUPPLY, 1916, PART XI.

REGULATION. Flow may be occasionally affected by a rock and brush diversion dam

just above gage. 

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

denned above 20 second-feet. Operation of water-stage recorder satisfactory.

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

height determined by inspecting gage-height graph. Record good for February,

March, and April, fair for December, poor for May. 

COOPERATION. Field data furnished by United States Reclamation Service, Klamath

project.

OLENE WASTEWAY AT OLENE, OREG.

LOCATION. In the SW. i sec. 14, T. 39 S., R. 10 E., at the flume on the "Fa> canal 

of the Klamath project that crosses Lost River at Olene, Klamath County, about 

4 miles upstream from Lost River dam.

RECORDS AVAILABLE. Irrigation seasons 1915 and 1916.

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. Records of total yearly 

run-off probably good.

COOPERATION. Records furnished by United' States Reclamation Service. No 

measurements during 1916.

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 "GB> 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, 1916.
286 SURFACE WATER SUPPLY, 1916, PART XI.

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. Gage readers, United States Reclamation Service employees. Gages above and below the intake gates at the Lost 

Eiver dam, 1 in the SW. J sec. 29, T. 39 S., E. 10 E., were read up to March 31, 

1916, and openings of the three gates recorded.

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 feet 

depth of water. Klamath River backs water normally up to head of canal.

EXTREMES OP DISCHARGE. Maximum discharge recorded during year, 443 secondfeet February 15, 2 to 12 p. m., for openings of 5.6 feet on all three gates, and a 

head of 0.85 foot.

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. If determined 

by coefficients of discharge defined in 1917, the discharge for 1916 would have 

been the greater. Canal dry at times. i

ICE. Stage-discharge relation unaffected by ice.

ACCURACY. Stage-discharge relation unstable, being affected by backwater from 

Klamath River. Daily discharge March 29 to April 28 ascertained according 

to the method outlined in Water-Supply Paper 345-E. 2 Individual discharge 

measurements, unless proper corrections are made for the slope in the water 

surface at the time of each measurement, plot very discordantly. These measurements, however, develop aerating curve called the "normal curve" when the 

discharge is corrected to correspond to that which would occur for a normal 

slope. This normal rating curve has been used in determining 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. Discharge coefficients for computing flow through the gates considered as orifices January 22 to 

March 28 have been obtained by plotting the coefficients derived from measurements divided into three groups according to gate openings. The measurements 

of 1917 define a new curve of coefficients for gate openings of 4 to 6 feet, which 

are 10 to 15 per cent smaller than those based on measurements made 1912 to 

1914. All earlier computations of discharge over 300 second-feet are probably 

somewhat in error. Records fair.

COOPERATION. Field data furnished by United States Reclamation Service.

G CANAL NEAR OLENE, OREG.

LOCATION. In the SW. i sec. 29, T. 39 S., R. 10 E., at intake at east end of Los 

River dam, 4 miles south of Olene, Klamath County.

RECORDS AVAILABLE. July 1, 1912, to September 30, 1916.

GAOE. Gage No. 1 the upper gage is a Stevens 8-day water-stage recorder 200 feet 

"below the intake; gage No. 2 is a similar recorder 11,000 feet downstream. Both 

gages set at same datum.

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 is a timber check at station 112, just below gage 

No. 2, which backs the water up to the intake.

EXTREMES OP DISCHARGE. Maximum discharge during irrigating season, May 1 to 

September 30, 124 second-feet August 7. Minimum discharge, 28 second-feet 

July?.

ACCURACY. Stage-discharge relation unstable, being affected by operation of check. 

Recorder No. 1 opeiated satisfactorily except May 6-11, July 6-14, 23-29, and 

August 4-8, 20, 21; September 2-11. Recorder No. 2 operated July 5 to September 2. One reading each day on staff gage used at other times. Daily 

discharge ascertained according to the method outlined in Water-Supply Paper 

345E.1 Individual discharge measurements, unless proper correction are made

for the slope in the water surface at the time of each measurement, plot 

very discordantly. These measurements, however, develop a well-defined 

rating curve called the "normal curve9' when the discharge is corrected to correspond to that which would occur for a normal slope. This normal rating curve 

has been used in the determination of estimates 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 well defined between 50 and 110 second-feet. Records fair when both recorders were working; poor at other times, as there was 

considerable fluctuation due to operation of check. 

COOPERATION. Field data and computations by United States Reclamation Service.

G canal diverts water from Lost River in the SW. J sec. 29, T. 39 S., R. 10 E., 

and irrigates land1 east of the lower part of the river and north of Tule Lake. Return

MIDDLE FORK OF SMITH RIVER NEAR CRESCENT CITY, CAL.

LOCATION. In the NE. \ SE. \ sec. 20, T. 17 N., R. 2 E., at highway bridge 800 feet 

above junction of North and Middle forks, one-eighth mile east of Gasquet, and 

14 miles northeast of Crescent City, Del Norte County.

DRAINAGE AREA. 146 square miles.

RECORDS AVAILABLE. September 8, 1911, to September 30, 1916 (not complete).

GAGE. Chain gage attached to downstream guard rail of bridge; May 26, 1913, an 

inclined staff in two sections was installed on right bank 60 feet upstream from 

bridge; original datum was not maintained; chain gage is read during low water 

when staff gage can not be read. Gage is read by A. W. Lewis.

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

CHANNEL AND CONTROL. Bed rough; composed of boulders and gravel; somewhat 

shifting. Banks are high and not subject to overflow.

EXTREMES OP DISCHARGE. Maximum stage recorded during year and period 1911-r 

1916: 17.5 feet at 1.30 p. m. November 25, 1915 (discharge, from extension of 

rating curve, about 14,300 second-feet J); minimum stage recorded, 3.45 feet 

(chain gage) at 10 a. m. October 21, 1915 (discharge, 38 second-feet).

DIVERSIONS. -^-None.

RE GUL ATIO N . None.

ACCURACY. Stage-discharge relation permanent. "Rating curve for chain gage, 

read below stage, 4.0 feet (discharge, 100 second-feet), fairly well denned; for 

staff gage, well denned below 8,000 second-feet and extended above. Gage 

read to quarter tenths twice daily. Daily discharge ascertained by applying 

mean daily gage height to rating table. Records obtained from chain gage fair; 

those from staff gage probably excellent.

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

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

1 Discharge published in Water-Supply Paper 391 is an error. It should have read "February 17,191? 

(discharge, from extension of rating curve, about 13,900 second-feet) * * *."

STREAM-GAGING STATIONS AND PUBLICATIONSRELATING TO WATER RESOURCES.

INTRODUCTION.

Investigation of water resources by the United States Geological 

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

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

it has comprised also investigation of such closely allied subjects as 

irrigation, water storage, water powers, 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 and eastern Gulf of Mexico basins.

III. Ohio River basin.

IV. St. Lawrence River basin. 

Y. 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.

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.

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 1916. 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 1916, are published in Water-Supply Papers 97, 124, 165, 

201, 241, 261, 281, 301, 321, 351, 381, 401, and 431, which contain 

records for the New England streams from 1903 to 191,6. Results of 

miscellaneous measurements are published by drainage basins.

In these papers and in the following lists the stations are arranged 

in downstream order. The mam stem of any river is determined 

by measuring or estimating its drainage area-* that is, the headwater 

stream having the largest drainage area is considered the continuation of the main stream, and local changes in name and lake surface 

are disregarded. All stations from the source to the mouth of the 

main stem of the river are presented first, and the tributaries in 

regular order from source to mouth follow, the streams in each 

tributary basin being listed before those of the next basin below.

In exception to this rule the records for Mississippi River are 

given in four parts, as indicated on page in, and the records for 

large lakes are taken up in order around the rim of the lake.

in response to a memorial from the California Miners' Association asking that a particular 

study be made of portions of the Sacramento and San Joaquin valleys affected by detritus 

from torrential streams. The report deals largely with geologic and physiographic aspects of 

the subject, traces the physical effects, past and future, of the hydraulic mining oi 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 the form of a folio. When all 

the folios are completed they will constitute the Geologic Atlas of the United States.

A folio is designated by the name of the principal town or of a prominent natural 

feature within the quadrangle. Each folio includes maps showing the topography, 

geology, underground structure, and mineral deposits of the area mapped and several 

pages of descriptive text. The text explains the maps and describes the topographic 

and geologic features of the country and its mineral products. The topographic 

map shows roads, railroads, waterways, and, by contour lines, the shapes of the hills 

and valleys and the height above sea level of all points in the quadrangle. The 

areal-geology map shows the distribution of the various rocks at the surfaces. The 

structural-geology map shows the relations of the rocks.to one another underground. 

The economic-geology map indicates the location of mineral deposits that are commercially valuable. The artesian-water map shows the depth to ground-water horizons. 

Economic-geology and artesian-water maps are included in folios, if the conditions 

in the areas mapped warrant their publication. The folios are of special interest to 

students of geography and geology and are valuable as guides in the development 

and utilization on mineral resources.

i Index maps showing 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.
PUBLICATIONS.

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 50 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.

All the folios contain descriptions of the drainage of the quadrangles. The folios 

in the following list contain also brief discussions of the underground waters in connection with the economic resourc^of the areas and more or less information concerning the utilization of the water resources.

An asterisk (*) indicates that the stock of the folio is exhausted.

traces the physical effects, p: ist and future, of the hydraulic mining of earlier decades, the similar effects which certain oth >r industries induce through stimulation of the erosion of the soil, 

and the influence of the restr ction 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.
