each station affected by the cooperative work.

PUBLICATIONS.

Measurements of stream flow have-been made at nearly 2,000 

points in the United States and also at many points in small areas 

in Seward Peninsula and the Yukon-Tanana region, Alaska, and in 

the Hawaiian Islands. During 1911 gaging stations were maintained 

by the Survey and the cooperating organizations at about 1,500 points 

in the United States, and many discharge measurements were made 

at other points. In connection with this work data were also collected in regard to precipitation, evaporation, storage reservoirs, 

river profiles, and water power in many sections of the country, and 

will be made available in the regular surface water-supply papers 

from time to time. A complete list of the gaging stations maintained 

by the Survey to and including 1910 and a list of the papers relating 

to the water supply of the country has been published by the Survey 

as Water-Supply Paper 280. An index to the reports containing 

stream flow measurements prior to 1904 has been published as WaterSupply Paper 119.

Plates I and II show the average run-off and rainfall in the United 

States as determined from the measurements of stream flow made 

by the Geological Survey and records of rainfall collected by the 

Weather Bureau.

For each calendar year there has been prepared a report embodying 

the stream-flow data collected during that year, which has been published either as a part of the annual report of the Director, as a bulletin, or as a water-supply paper, as shown by the following table:

NOTE. No data regarding stream flow are given in the 15th and 17th annual reports.

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

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

to 1911. The data for any particular station will 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 

1911, are published in Water-Supply Papers 97, 124, 165, 201, 241, 

261,281, and 301, which contain records for the New England streams

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 which represent a rate of flow, as secondfeet, gallons per minute, miner's inches, and discharge in second-feet 

per square mile; and (2) those which represent the actual quantity 

of water, as run-off in depth in inches and acre-feet. The units used 

in this series of reports are second-feet, second-feet per square mile, 

run-off in inches and acre-feet. They may be denned as follows:
PACIFIC COAST IN CALIFORNIA. 13

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

the unit for the rate of discharge of water flowing in a stream 1 foot 

wide, 1 foot deep, at a rate 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 following table of equivalents.

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

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

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

regards time and area.

"Run-off in inches" is the depth to which the drainage area would 

be covered if all the water flowing from it in a given period were conserved and uniformly distributed on the surface. It is used for 

comparing run-off with rainfall, which is usually expressed in depth 

in inches.

An "acre-foot" is equivalent to 43,560 cubic feet, and 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 work.

EXPLANATION OF DATA.

For each, regular current-meter gaging station the following data 

are given: Description of the station, list of discharge measurements, 

table of daily gage heights, table of daily discharges, table of monthly 

and yearly discharges and run-off. For stations located at weirs or 

dams the gage-height table is omitted.
PACIFIC COAST IN CALIFOBSTIA. 15

In addii/ion to statements regarding the location and installation 

of current-meter stations, the descriptions give information in regard 

to any conditions which may affect the constancy of the relation of 

gage height to discharge, covering such points as ice, logging, shifting

channels, and backwater; also information regarding diversions

which decrease the total flow at the measuring section. Statements 

are also made regarding the accuracy and reliability of the data.

The tab e of daily gage-heights records the daily fluctuations of the 

surface of the river as found from the mean of the gage readings 

taken each day, usually in the morning and in the evening. The 

gage height given in the table represents the elevation of the surface 

of the water above the zero of the gage. All gage heights affected 

by the presence of ice in the streams or by backwater from obstructions are published as recorded, with suitable footnotes. The rating 

table is not applicable for such periods unless the proper corrections 

to the gage heights are known and applied. Attention is called to 

the fact that the zero of the gage is placed at an arbitrary datum and 

has no relation to zero flow or the bottom of the river. In general, 

the zero is located somewhat below the lowest known flow, so that 

negative readings shall not occur.

The discharge measurements and gage heights are the base data 

from which rating tables, daily discharge tables, and monthly discharge tables are computed.

The rating table gives, either directly or by interpolation, the discharge in second-feet corresponding to every stage of the river recorded 

during the period for which it is applicable. It is not published in 

this report, but can be determined from the tables of daily gage 

heights and daily discharge, as follows:

First plot the discharge measurements for the current and earlier 

years on cross-section paper, with gage heights in feet as ordinates and 

discharge in second-feet as abscissas. Then tabulate a number of 

gage heights taken from the daily gage-height table for the complete range of stage given and the corresponding discharges for the 

days selected from the daily discharge table and plot the values on 

cross-section paper. The last points plotted will define the rating 

curve used and will lie among the plotted discharge measurements. 

After drawing the rating curve, a table can be developed by scaling 

off the discharge in second-feet for each tenth foot of gage height. 

These values should be so adjusted that the first differences shall 

always be increasing or constant, except for known backwater 

periods.

The table of daily discharges gives the discharges in second-feet 

corresponding to the observed gage heights as determined from the 

rating tables.
16 SURFACE WATER SUPPLY, 1911, PART XI.

In the table of monthly discharge the column headed "Maximum" 

gives the mean flow, as determined from the rating table, 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 at "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 the computations for the remaining columns, 

which are defined on page 13, are based.

The field methods used in the collection of the data presented in 

this series of reports are described in the introductory sections of 

Water-Supply Papers 261 to 272, inclusive, "Surface water supply of 

the United States, 1909." Plate III shows typical gaging stations, 

indicating the method of suspending the current meter; Plate IV 

shows current meters l used in the work.

ACCURACY AND RELIABILITY OF FIELD DATA AND 

COMPARATIVE RESULTS.

The accuracy of stream-flow data depends primarily on the natural 

conditions at the gaging station and on the methods and care with 

which the data are collected. Errors of the first group depend on the 

degree of permanency of channel and of permanency of the relation 

between discharge and stage.

Errors of the second class are due, first, to errors in observation of 

stage; second, to errors in measurements of flow; and, third, to errors 

due to misinterpretation of stage and flow data.

In order to give engineers and others information regarding the 

probable accuracy of the computed results, footnotes are added to the 

daily discharge tables, stating the probable accuracy of the rating 

tables used, and an accuracy column is inserted in the monthly discharge table. 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" or "approximate" 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 accuracy column in the monthly discharge table does not 

apply to the maximum or minimum nor to any individual day, but to 

the monthly mean. It is based on the accuracy of the rating, the 

probable reliability of the observer, and knowledge of local conditions.

In this column, A indicates that the mean monthly flow is probably 

accurate within 5 per cent; B, within 10 per cent; C, within 15 per 

cent; D, within 25 per cent. Special conditions are covered by footnotes.

Even though the monthly means for any station may represent 

with a high degree of accuracy the quantity of water flowing past the 

gage, the figures showing discharge per square mile and depth of runoff in inches may be subject to gross errors which result from including in the measured drainage area large noncontributing districts or 

omitting estimates of water diverted for irrigation or other use, and 

they should, therefore, be considered as only approximate, particularly for periods of irrigation or of low water. For these errors it is 

as a rule not feasible to make adequate correction.

In general, the base data collected each year by the Survey engineers are published, not only to comply with the law, but also to 

afford any engineer the means of examining and adjusting to his own 

needs the results of the computations. The table of monthly discharge is so arranged as to give only a general idea of the flow at the 

station and should not be used for other than preliminary estimates. 

The determinations of daily discharge allow more detailed studies of 

the variation in flow by which the "period of deficiency may be determined.

It should be borne in mind that the observations in each succeeding 

year may be expected to throw new light on data already'collected 

and published, and the engineer who makes use of the figures presented in these papers should verify all ratings and make such adjustments for earlier years as may seem necessary.

NOTE. About 10,500 acre-feet were impounded in the Morena reservoir during 1911; hence the total 

run-off from the Cottonwood drainage during this year was about 15,400 acre-feet.

DULZURA CONDUIT NEAR JAMUL, CAL.

Location. About 12 miles below intake and 9 miles southeast of Jamul. During

1909 and 1910 station was located 1£ miles below intake. 

Records available. January 1, 1909, to December 31, 1911. 

Gage. Lietz water register at weir. 

Discharge. Computed from gage height record at an 8-foot steel plate weir about

1J miles above lower end of conduit. 

Accuracy. Automatic gage is checked twice each day by patrolman. Results

are believed to be excellent. 

Cooperation. Daily discharge furnished by Southern California Mountain Water

Co. through M. M. O'Shaughnessy, chief engineer.

The Dulzura conduit diverts water from Cottonwood and Pine Valley creeks, about 

half a mile above their junction, into Dulzura Creek drainage. From the end of the 

conduit the water flows down the natural channel of Dulzura Creek into the Lower 

Otay reservoir. The water is used for municipal purposes at San Diego. The conduit 

is 13.38 miles long and is concrete lined except 4,490 feet of flume and 9,219 feet of 

tunnel. The average width is about 5 feet and the depth 4 feet 2 inches. The grade 

is 4 feet in 5,000 and the capacity 40,000,000 gallons in 24 hours. The seepage loss 

between intake and measuring weir amounts to about 3 per cent.

Daily discharge, in second-feet, of Dulzura conduit near Jamul, Cal., for 1911.

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

three-fourths mile north of Lakeside.

Records available. December 3, 1905, to December 31, 1911.

Drainage area. 208 square miles.

Gage. Staff in three sections on left bank 100 feet above ford.

Channel. Shifting sand.

Discharge measurements. Made from car and cable at gage and by wading.

Diversions. San Diego flume heads at diverting dam about 1,000 feet below 

Boulder Creek and about 15 miles above the station. Five pumping plants, 1 

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

of the stream. The capacity of these plants ranges from about 0.5 to 2.5 secondfeet. Cuyamaca reservoir, on the headwaters of Boulder Creek, has a capacity 

of 11,410 acre-feet.

Accuracy. Results are fair.

SAN DIEGO FLUME NEAR LAKESIDE, CAL.

Location. One-fourth, mile above trestle crossing at Los Coches Creek, about 3

miles southeast of Lakeside.

Records available. January 1, 1907, to December 31, 1911.

Gage. Depth of water in flume is measured at reference point at patrolman's cabin. 

Discharge measurements. Made in flume at reference point.
PACIFIC COAST IN CALIFORNIA.

Storage and diversions. The Cuyamaca dam, on the headwaters of Boulder 

Creek, was built in 1886. It was one of the first earth dams constructed in California for irrigation storage. In 1894 it was enlarged and is now 41J feet high 

and 635 feet long. The capacity of this reservoir is 11,400 acre-feet. From 

Cuyamaca reservoir the water flows down the natural channel of Boulder Creek 

and San Diego Eiver to the intake of the San Diego flume, a distance of 12J miles.

Accuracy. Rating curve is fairly well defined. On account of leakage and 

diversion for irrigation on the Capitan Grande Indian Reservation, the record 

does not show the total diversion. Results are good.

Cooperation. Gage-height record furnished by the Cuyamaca Water Co.

The San Diego flume, which is over 30 miles in length, is 6 feet wide and 16 

inches deep and has a capacity of about 16 second-feet. 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. It now supplies water for irrigation for 

about 6,000 acres. There is considerable loss between intake and gaging station 

due to leakage in flume. Occasionally water from the South Fork of San Diego 

River is diverted into this flume. Water is diverted from the San Diego flume above 

the station for irrigation on the Capitan Grande Indian Reservation.

Discharge measurements of San Diego flume near Lakeside, Gal., in 1911.

32 SUEFACE WATEE SUPPLY, 1911, PAET XI.

SAN LUIS REY RIVER NEAR PALA, CAL.

Location. At ford on road to Sickler's mill, in the NW. J sec. 31, T. 9 S., R. 1 W., 

San Bernardino meridian, about 4 miles southeast of Pala.

Records available. October 9, 1903 to June 30, 1911.

Drainage area. 318 square miles.

Gage. Staff in two sections on left bank. The gage datum was lowered 4.66 feet 

on November 13, 1906.

Channel. Sand, gravel, and bowlders; shifting.

Discharge measurements. Made from car and cable 75 feet below gage and by 

wading.

Diversions and storage. 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, about 6 miles northeast of Escondido, is used for irrigation 

and municipal purposes at Escondido and vicinity. The capacity of the reservoir is 3,120 acre-feet. A small ditch diverts water from Pauma Creek for irrigation on the Pauma Indian Reservation. A small ditch 1 mile above the station 

supplies water for irrigation on the Sickler ranch.

Accuracy. Results fair.

Cooperation. Maintained in cooperation with Volcan Land & Water Co.

NOTE. Daily discharge determined from three fairly well-defined rating curves applicable Jan. 1 to Feb. 

4, Feb. 5 to Mar. 4, and Mar. 5 to Dec. 31. Daily discharge for days on which gage was not read determined 

by means of hydrograph comparison with discharge of Santa Ana River near Mentone, San Diego River 

at Lakeside, and Sweetwater River at Descanso. These values are only very rough approximations.

SANTA ANA RIVER BASIN. 

SANTA ANA RIVER NEAR MENTONE, CAL.

Location. Just above road crossing opposite Warm Springs Canyon, in the SW. J 

SW. J sec. 34, T. 1 N., R. 2 W., San Bernardino meridian, three-fourths of a mile 

below intake of Pacific Light & Power Co. 's canal, about 2 miles above the mouth 

of the canyon, and 5 miles northeast of Mentone.

Records available. July 1, 1896, to December 31, 1911.

Drainage area. 182 square miles.

Gage. Vertical staff on right bank about 100 feet above ford. The present gage was 

installed February 25, 1910. Previous to this date various gages were used. 

The original datum has not been maintained.

Channel. Gravel and bowlders; will shift during high water. 

49938° WSP 311 12 3
34 SURFACE WATER SUPPLY, 1911, PART XI.

Discharge measurements. The flood of January, 1910, destroyed the car and cable. 

This equipment has not been replaced as it is difficult to reach the station at high 

water. Measurements are made by wading at medium and low stages.

Artificial control. Southern California Edison Co.'s power plants Nos. 1 and 2 are 

located 5J and 2f miles, respectively, above the Mentone plant at the mouth of 

the canyon. The intake of the Pacific Light & Power Co.'s canal is at plant 

No. 2. The tail race from this plant discharges into the canal.

Diversions. The Green Spot pipe line diverts water from the forebay at the Mentone 

power house. Water is stored on Bear Creek at Bear Valley reservoir.

Accuracy. Results are good, except at extreme high stages.

NOTE. During October and November a retaining wall was under construction just above the county 

bridge to shut water out of an old channel made by the preceding winter's flood. Water was diverted 

through this old channel to facilitate construction about Nov. 1-6 and 12-13. Discharge of river was not 

registered by the gage on these days. Daily discharge determined from a well-defined rating curve. Discharge interpolated Nov. 1-6 and 12-13.

SANTA YNEZ RIVER BASIN. 

SANTA YNEZ RIVER NEAR SANTA BARBARA, CAL.

Location. One-fourth mile below Gibraltar dam site, in the NE. \ NE. \ sec. 15, 

T. 5 N., R. 27 W., about 7 miles north of Santa Barbara. Mono Creek enters 3J 

miles below the station.

Records available. November 1, 1903, to April 30, 1907; October 1, 1907, to January 31, 1908; and February 6, 1910, to December 31, 1911. The station was 

maintained about 5 miles above the present location from November 21, 1902, to 

June 20, 1903.

Drainage area. 207 square miles.

Gage. Staff in three sections about 900 feet below north portal of the Santa Barbara 

water-supply tunnel. On April 13, 1911, gage datum was lowered 5.00 feet. All 

gage heights for 1911 are referred to the new datum.

Channel. Sand and gravel; shifts greatly at extreme high stages; relatively permanent at low stages.

Discharge measurements. Made from car and cable at gage and by wading at 

low water.

Accuracy. The flood in March, 1911, greatly changed the channel, and hence no 

reliable estimates can be made for the period February 6, 1910, to March 14, 1911. 

Frequent measurements were secured during 1911, and results are good.

Cooperation. Maintained in cooperation with Santa Barbara Water Commission.

SAUNAS RIVER BASIN.

ARROYO SECO NEAR SOLEDAD, CAL.

Location. At Pettitt's ranch in sec. 21, T. 19 S., R. 6. E., about 15 miles south of

Soledad.

Records available. January 1, 1901 to December 31, 1911. 

Drainage area. 215 square miles. 

Gage. Staff in two sections on right bank. 

Channel. Gravel and fairly permanent. 

Discharge measurements. Made from car and cable 300 feet below gage and by

wading about one-fourth mile above cable at low stages. 

Accuracy. Frequent discharge measurements are secured. They plot a little

scattering on the rating curve but results are considered reliable. The March

flood scoured out the channel and a new rating curve was used after March 7.

64 SUBFACE WATER SUPPLY, 1911, PAET XI.

TULARE LAKE IN KINGS COUNTY CAL.

Tulare Lake is about 30 miles directly south of Fresno and 40 miles 

northwest of Bakersfield. 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 an 

area of about 274 square miles, a maximum depth of 12.4 feet, an average length of 20 miles, and a width of 13.5 miles; the water's edge was 

3 miles from the town of Corcoran, and the water surface about 12 

feet below. The lake surface reached its greatest height in the summer of 1907, when it had a maximum depth of nearly 14 feet. Since 

July, 1907, it has been gradually subsiding.

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

bottom has an elevation of approximately 180 feet above mean sea 

level and covers about 55 square miles. The lowest point on the 

crest of the delta ridge to the north is about 27 feet higher than thebottom of the lake. Natural overflow will not occur, therefore, until 

the lake has a maximum depth of nearly 30 feet and an area of nearly 

1,000 square miles.

During 1906 and a part of 1907 a record of the stage of the lakewas kept by means of a Government staff gage located near the 

entrance of Kings River near Lemoore, Cal., at the middle of sec. 4, 

T. 21 S., R. 20 E., M. D. B. and M. The zero of the gage was at ar 

elevation of 175.1 feet above mean sea level, or 4 feet below the 

bottom of the lake (elevation 179.1 feet). On May 11, 1907, a staff 

gage was set near Corcoran, Cal., referred to the same datum anc! 

used until July 30, 1909.

On July 28, 1910, a vertical staff gage, in two sections, was installed 

on the section line just south of the corner to sees. 27, 28, 33, and 34, 

T. 20 S., R. 20 E., about 10 miles south of Lemoore near Stratford 

post office. The datum on this gage is 171.0 feet above sea level.

All published gage records have been reduced to show the actual 

depth of the water on the lowest point of the lake bed.

Daily gage height, in feet, of Tulare Lake near Stratford, Cal., for 1911.

TTIOLTIMNE RIVER NEAR LAGRANGE, CAL.

Location. At Lagrange dam, in the SE. J sec. 17, T. 3 S., R. 14 E., about 2 miles 

above Lagrange.

Records available. August 30, 1895, to December 31,1911.

Drainage area. 1,500 square miles.

Gage. Painted on rock ledge on right bank 80 feet above dam. Zero of gage is at 

average elevation of crest of dam. Previous to April 1, 1908, gage was located at 

highway bridge at Lagrange.

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

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

from current meter measurements made at highway bridge, about 2 miles below 

the dam, corrected to give discharge at dam. To determine the total flow of 

Tuolumne River at Lagrange, the flow over the dam is added to the discharge 

of Modesto, Turlock, and Lagrange Water & Power Co.'s canals.

Diversions. Modesto and Turlock canals divert at dam. Lagrange Water & Power 

Co.'s canal heads 13 miles above the dam. The water from the power canal 

is returned to the river below the dam and about half a mile above the bridge.

Accuracy. Results are excellent except at extreme low water. The combined 

record of river and canals is slightly affected by seepage from dam and canals.

Daily gage height, in feet, of Tuolumne River on crest of dam near Lagrange, Cal.,for

1911.

TURLOCK CANAL NEAR LAGRANGE, CAL.

Location. Below tunnel on left bank of Tuolumne River at Lagrange dam, about

2 miles northeast of Lagrange.

Records available. July, 1899, to December 31, 1911. 

Gage. Vertical staff float in concrete well, 190 feet below intake and below the

spillway. 

Discharge measurements. Made from footbridge at Morgan flume half a mile

below gage. 

Accuracy. Results are good. It is believed that the gage height record is slightly

affected by change in stage of river at intake. 

Cooperation. After June 30, 1911, gage height record was furnished by the Turlock

irrigation district, through Burton Smith, chief engineer.

LAGRANGE WATER & POWER CO.'s CANAL NEAR LAGRANGE, CAL.

Location. At the flume opposite Lagrange dam, about 1J miles above power house

and 2 miles northeast of Lagrange. 

Records available. 1908 to 1911 (not complete). 

Gage. Depth of water in flume is measured at reference point. 

Discharge measurements. Made in flume near point at which gage heights are

observed.

Accuracy. Results are good for period covered by gage heights. 

Cooperation. Gage-height record furnished by Turlock irrigation district through

Burton Smith, chief engineer.

The Lagrange Water & Power Co.'s canal takes water from the south side of Tuolumne River at Indian Bar, about 15 miles above the town of Lagrange. This canal 

was built in the early days to supply water for hydraulic mining in the vicinity of 

Lagrange, and it is now locally known as the "old mining ditch." Recently it has 

been thoroughly repaired and is now used as a supply canal for the new hydroelectr c 

plant which was installed in the latter part of 1907. The power house is situated on 

the bank of the river about half a mile above the town of Lagrange and is below tt e 

dam and headworks of the Turlock and Modesto irrigation canals.

STANISLAUS EIVEE AT KNIGHTS FEEKY, CAL.

Location. At Knights Ferry, in the NE. £ sec. 29, T. 1 S., R. 12 E., about 25 miles 

below mouth of South Fork, and 12 miles northeast of Oakdale.

Records available. May 19, 1903, to December 31, 1911. From May 3, 1895, to 

February 16,1901 a station was maintained one-half mile north of Oakdale.

Drainage area. 935 square miles.

Gage. Staff in five sections on right bank; four vertical and one inclined. 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.

Channel. Small bowlders and gravel; slightly shifting at high stages.

Discharge measurements. Car and cable 25 feet above gage.

Storage and diversions. Ditches diverting water for use in mining are numerous above the station. Water is also diverted from the Sou'th Fork into the 

Tuolumne basin and from the North Fork for use in the vicinity of Murphy and 

Angeles. The intake of the Stanislaus Water Co.'s canal is about 3 miles above 

Knights Ferry. This canal returns water below the station. Schell ditch diverts 

about 6 second-feet from this canal above the gaging station on the canal. Considerable storage is developed on Middle Fork of Stanislaus River for power 

purposes.

Accuracy. Results are affected by the many diversions for irrigation and mining 

and by the operation of a power plant a short distance above the gage. Record 

is considered good except at extreme low water and flood stage.

The discharge of the river at this point is determined by combining the discharge 

at the river gaging station with the discharge of Stanislaus Water Co.'s canal and 

Schell's ditch.

SACRAMENTO EIVEE NEAE EED BLUFF, CAL.

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

miles above Red Bluff 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.

Records available. January 28, 1902, to December 31, 1911. 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 gaging station was 

maintained at Jellys Ferry, 12 miles above Red Bluff.

Drainage area. 10,400 square miles, including Goose Lake drainage area of 1,090 

square miles.

Gage. Staff in three sections on the left bank. Several gages have been used at 

this station, but all observations have been reduced to the present datum.

Channel. Coarse gravel and small bowlders, and is permanent.

Discharge measurements. Made from a car and cable a short distance above the

Diversions and storage. No storage of any importance has been developed in the 

drainage area above this station. A small amount of water is diverted from some 

of the minor tributaries for irrigation. With this exception the record at this 

station gives the natural run-off from the basin.

Accuracy. Results at this station are excellent.

a Includes Goose Lake drainage basin 1,090 square miles. 

COTTONWOOD CREEK NEAR LAKEVIEW, OR.EG.

Location. In sec. 29, T. 38 S., R. 19 E., about 10 miles west of Lakeview and about

half a mile below the site of the Oregon Valley Land Co.'s proposed dam. 

Records available. November 22, 1908, to December 31, 1911. 

Drainage area. 30 square miles. 

Gage. An inclined staff on the left bank about 25 feet above the footbridge. On

November 22, 1908, a 10sfoot trapezoidal weir was installed and a gage placed

above it as an index to head. On January 19, 1909, the length of the weir was

increased to 15 feet, a footbridge was installed about 1,000 feet below it, and an

inclined gage (that now in use) was set on the left bank. 

Channel. Clean gravel; probably permanent; one at all stages; both banks low and

wooded and may be overflowed at flood stages.

Winter flow. Affected by ice for short periods during extremely cold weather. 

Discharge measurements. Made from the footbridge about one-fourth mile below

a former camp and half a mile below the weir. 

Accuracy. The creek is subject to large diurnal fluctuations during the spring, and

as the gage has been read only once or twice daily the determinations of flow are

subject to considerable error. 

Cooperation. Station maintained in cooperation with the Lakeview Irrigation &

Power Co.

The following discharge measurement was made by R. W. Davenport: 

May 4, 1911: Gage height, 1.58 feet; discharge, 95 second-feet.

NOTE. Ice probably existed at this station from about Jan. 1 to Mar. 10 and Dec. 20 to 31; effect on the 

relation of gage height to discharge was not great during January but was considerable during February, 

March, and December. Corrections have been applied to many of the gage readings from Mar. 17 to May 

17 to allow for diurnal fluctuation of stage.

accuracy rating of the records, during the spring high water, at this station is lowered by the diurnal fluctuations in stage.

DREWS CREEK NEAR LAKEVIEW, OREG.

Location. At a wagon bridge in see. 4, T. 40 S., R. 18 E., 1 mile below Drews Creel1

Dam and 22 miles southwest of Lakeview. 

Records available. January 16, 1909, to December 31, 1911. 

Drainage area. 211 square miles. 

Gages. At station No. 1, an inclined staff at the dam site, established January 16.

1909. Gage at station No. 2 at a dump car bridge 100 feet below the dam site 

read from November 20, 1909, to March 1, 1910. Gage at present site, station

No. 3, a staff established March 1, 1910. A Barrett-Lawrence automatic gage

was installed December 13, 1911. 

Channel. Gravel; not likely to shift at high stages; creek overflows into a second

channel; bed usually dry two or three months each year.

Discharge measurements. Made from wagon bridge near gage or by wading. 

Winter flow. Affected by ice. Effect was not same in 1911 and was not taken

into consideration in the estimates of discharge.
PACIFIC COAST IN CALIFOENIA. 145

Accuracy. The gage readings two daily indicate that the diurnal fluctuation ia 

not marked except at extreme high water. Allowance has been made for the 

effect of ice during the winter months so that the accuracy of the estimate of total 

run-off is not affected.

Cooperation. Observations made and records furnished by the Lakeview Irrigation 

& Power Co.

HAT CREEK AT HAW KINS RANCH, NEAR HAT CREEK, CAL.

Location. At Hawkins ranch, in sec. 5, T. 33 N., R. 5 E., 6 miles above Hat Creek.

Records available. August 15 to December 31, 1911.

Drainage area. Not measured.

Gage. Vertical staff on upstream end of right abutment.

Channel. Fairly smooth and probably permanent.

Discharge measurements. Made from downstream side of footbridge.

Diversions. The only diversion for irrigation of any importance above this station 

is the H. M. Wilcox ditch, which heads about one-half mile above the gage. About 

40 second-feet is diverted by this canal at irregular intervals, as shown by the 

observer's notes.

The following discharge measurement was made by J. E. Stewart: 

August 15, 1911: Gage height, 2.35 feet; discharge, 134 second-feet.

Daily gage height, in feet, of Hat Creek at Hawkins ranch, near Hat Creek, Col., far 1911.

NOTE. Rise in gage height Aug. 17, Sept. 1, and Sept. 23 caused by turning in of irrigation ditch above 

the station; fall in gage heights Aug. 23 and Sept. 12 caused by turning out of irrigation ditch above station.

HAT CREEK AT HAT CREEK, CAL.

Location. At the private highway bridge, or Morris ranch, in the Lassen National 

Forest, in the SE. \ sec. 10, T. 34 N., R. 4 E., M. D. M., 300 yards north of Hat 

Creek post office.

Records available. September 22, 1910, to December 31, 1911.

Drainage area. Not measured.

Gage. Vertical staff fastened to downstream end of right abutment of bridge.

Channel. Gravel and small bowlders, and appears permanent.

Discharge measurements. Made from downstream side of bridge.

Diversions. On account of the diversions for irrigation above the station this record does not show the natural run-off from this drainage. On May 13, 1911, the 

nine ditches were diverting a total of 110 second-feet. Of this amount, it was 

estimated that 55 second-feet was returned to the stream above the gage.

Cooperation. Gage-height record furnished by United States Forest Service.

Sufficient measurements have not been made to develop a rating curve for this 

station.

NOTE. Daily discharge determined from a fairly well-defined rating curve; discharge Nov. 26 to 29, 

Dec. 1 to 7, and 9 to 19,1910, estimated from records of discharge of Pit River near Ydalpom, and precipitation records.

For days on which gage was not read during April and May, 1911, the discharge was determined from 

hydrographic comparison with McCloud Elver at Baird. Daily discharge interpolated for all other days 

on which gage was not read from June to December. Estimates of daily discharge for days on which gage 

was not read are roughly approximate and should be used with caution.

MONTGOMERY CREEK AT MONTGOMERY CREEK, CAL.

Location. At highway bridge in sec. 36, T. 35 N., R. 1 W., about one-fourth mile 

south of Montgomery Creek post office, and 2 miles above junction with Pit 

River.

Records available. August 11 to December 31, 1911.

Drainage area. Not measured.

Gage. Vertical staff on a large alder tree on left bank 70 feet below the bridge.

Channel. Small bowlders and gravel and is rough.

Diversions. About 5 miles above the station, the Terry Lumber Co. diverts water 

from this stream which is discharged into Little Cow Creek. During the logging 

season, from June to December, this diversion is from 8 to 10 second-feet. For 

the remainder of the year the amount is reduced to about 6 second-feet.

The following discharge measurement was made by J. E. Stewart by wading 80 

feet below the gage: 

August 11, 1911: Gage height, 0.74 foot; discharge, 23 second-feet.

Daily gage height, in feet, of Montgomery Creek at Montgomery Creek, Cal., for 1911.

to 8 or 10 second-feet. For the remainder of the year this is reduced to about 6 

second-feet.

The following discharge measurement was made by J. E. Stewart by wading 600 

feet above the gage: 

August 9, 1911: Gage height, 1.62 feet; discharge, 8.7 second-feet.

Daily gage height, in feet, of Little Cow Creek at Palo Cedro, Cal.,for 1911.

LITTLE STONY CREEK NEAR LODOGA, CAL.

Location. At East Park reservoir, 4 miles above junction with Stony Creek and 3J

miles northwest of Lodoga.

Records available. January 1, 1908, to December 31, 1911. 

Drainage area. 102 square miles. 

Gage. Previous to December 1, 1910, the station was maintained a short distance

below the present site. Several gages with independent datums were used.

Beginning with December 1, 1910, the record is from the gage at the dam. 

Discharge. Computed from gage heights observed at the dam. Correction has been

made for evaporation, which is determined from records obtained from an evaporation pan at the reservoir. 

Accuracy. Considerable care is used in collecting these data and results should

be good. 

Cooperation. Record furnished by United States Reclamation Service through

A. N. Burch, acting project engineer.

Daily gage height, in feet, of East Park reservoir near Lodoga, Cal., for 1911.

[J. Lea, observer.]

FEATHER RIVER AND TRIBUTARIES. 

FEATHER RIVER AT OROVILLE, CAL.

Location. At highway bridge at Oroville, in sec. 8, T. 19 N., R. 4 E., 6 miles bekw 

junction of North and Middle Forks and 30 miles above the mouth of Yuba River.

Records available. January 1, 1902, to December 31, 1911.

Drainage area. 3,640 square miles.

Gage. United States Weather Bureau vertical staff gage on pier of highway bridge 

on right bank. This station was maintained at bridge from 1902 to 1905. Ir 

December, 1905, a gage was installed on the left bank about 1,000 feet upstream. 

Gage heights for 1906-1910 were referred to this gage. The Weather Bureau gage 

was read during 1911. \

Channel. Somewhat shifting at high stages.

Discharge measurements. Made from car and cable 1,000 feet above bridge.

Accuracy. Discharge rating curves for 1911 are good. Daily and monthly discharges 

are withheld, however, pending the verifications of the gage heights for the latter 

part of the year.

Cooperation. Gage-height record furnished by United States Weather Bureav 

through N. R. Taylor, local forecaster.

Discharge measurements of Feather River at Oroville, Cal., in 1911.

NOTE. Daily discharge determined from a rating curve based on discharge measurements made during 

1910 to 1912, and which is well defined above a discharge of 3,000 second-feet, and fairly well defined below

MIDDLE FORK OF YUBA RIVER 1 NEAR NORTH SAN JUAN, CAL.

Location. Below highway bridge at Freemans Bridge, in the N. J NW. J sec. 23,

T. 18 N., R. 8 E., in the Tahoe National Forest, 1£ miles northeast of North San

Juan in Tahoe National Forest. Oregon Creek enters three-fourths mile above,

Moonshine Creek one-fourth mile below, and North Fork of Yuba River about 4

miles below the station.

Records available. October 27, 1910, to December 31, 1911. 

Drainage area. Not measured. 

Grage. Vertical staff wedged between two large bowlders on right bank one-fourth

mile below the bridge. 

Channel. Gravel and email bowlders. 

Discharge measurements. Made from highway bridge or by wading. As the

channel is very rough at the bridge, a car and cable were installed on November

7, 1911, 200 feet above the gage. 

IVinter flow. Some ice in the stream during the last week in December. This

occurrence is unusual. 

Accuracy. As measurements made from the bridge are not considered reliable,

estimates are withheld until measurements at the cable section are available. 

Cooperation. Previous to August 21, 1911, gage-height record was furnished by

United States Forest Service. Discharge measurements also furnished by the

Forest Service.

YTTBA RIVER NEAR SMARTSVILLE, CAL.

Location. At The Narrows, in sec. 22, T. 16 N., R. 6 E., 1 mile north of Smartsville

and 18 miles above the junction with Feather River. 

Records available. June 2, 1903, to December 31, 1911. 

Drainage area. 1,220 square miles. 

Gage. Vertical staff in four sections. Three sections are on left bank and one on

right bank. On account of the gradual erosion of the channel the gage datum

was lowered 10 feet on August 1, 1906. 

Channel. Gravel and small bowlders, and is shifting. As the result of extensive

placer mining in the early days the channel has been filled with an enormous

quantity of tailings. At the station the depth of mining debris is more than 80

feet.

Discharge measurements. Made from car and cable at gage. 

Diversions and storage. Water is diverted for power and irrigation above the

station. Several small glacial lakes near the headwaters of the South Fork of

Yuba are utilized as storage reservoirs. 

Accuracy. Conditions for obtaining accurate discharge data at high stages are poor,

owing to the shifting of the channel and the torrential nature of the stream.

Results at low and medium stages are good at high water they should be considered approximate.

194 SURFACE WATER SUPPLY, 1911, PART XI.

AMERICAN RIVER AT FAIROAKS, CAL.

Location. At highway bridge, 1,500 feet northwest of Southern Pacific Co.'s railroad station at Fairoaks Bridge and half a mile southeast of Fairoaks.

Records available. November 3, 1904, to December 31, 1911.

Drainage area. 1,910 square miles.

Gage. Painted on right abutment of bridge near downstream end, with a vertical 

staff for low water. The position of the gage has been changed several times since 

the station was established, but no change has been made in its datum.

Channel. Gravel and small bowlders; shifts slightly at high water.

Discharge measurements. Made from downstream side of bridge and by wading.

Diversions. Water is diverted and stored for power and irrigation above the station.

Accuracy. A comparison of the hydrographs of daily gage heights at Folsom anc1 

at Fairoaks for 1911 indicates that both records are good for the first four months 

but not from May 1 to August 9. Comparison of observer's with hydrographer's 

readings on May 6 and July 8 indicates that the Fairoaks records are much ir 

error on these two days and hence, inferentially, for the rest of tho above-notec1 

period. Comparisons with records of stations on other streams in a situatior 

eimilar to that of the American River, indicate that the Folsom record is the better. 

The values published in the first table of gage heights are uncorrected gage heights 

The gage heights published in the second table are corrected by comparison witb 

the record at Folsom.

The record at Fairoaks from August 10 to September 30, 1911, is considered 

fairly satisfactory. It does not agree with the Folsom records, but these are knowr 

to be poor at extreme low stage, as part of the water is by-passed around the 

gage. The stage during this period did not vary greatly. The measurement 

made October 3 confirms the record for the last part of the period, and preliminary 

estimates of discharge at Placerville and Colfax tend to confirm the gage heightr 

August 10 to September 30.

Readings made by a new observer October 1 to December 31 are about 2 feet 

too high as compared with gage heights at Folsom and -preliminary estimates of 

discharge at Placerville, Colfax, and East Auburn, and accordingly are not published. The rating curves developed for 1911 are good.

NOTE. Daily discharge determined from two curves which are fairly well defined, except at high stages 

where theyare somewhat poorly defined and are applicable as follows: Jan. 1 to Apr. 30 and May 1 to 

Dec. 31, 1911. Discharge May 12 to about July 15 subject to 5 to 20 per cent error. The apparent rise 

June 7 is due to error of gage readings.

PUTAH CREEK AT WINTERS, CAL.

Location. Just below Southern Pacific Co.'s railroad bridge in Winters, in the Rio

de los Putos grant.

Records available. September 26, 1905, to December 31, 1911. ' 

Drainage area. 805 square miles. 

Gage. Staff in five sections on left bank, 600 feet below bridge. An auxiliary

vertical staff on right bank is used for low water. The original gage datum has

been maintained.

Channel. Sand and gravel and somewhat shifting. Two channels at low water. 

Discharge measurements. Made from car and cable at gage and by wading. 

Diversions. With the exception of a small amount of water pumped for irrigation,

there are no diversions above the station. 

Accuracy. Results are fair except for low water, which are only approximate.

Beginning about May 17, 1911, a temporary dam was constructed across the creek

500 feet below the gages, ponding water for recreation purposes. This dam was

partially destroyed October 2, 1911.

NOTE, Gage heights observed on North Channel gage Jan. 1 to May 22 (except Mar. 12 and 13, 

which were the same on both gages and June 19 to 24. Gage heights observed on south gage May 23 to 

June 18 and June 25 to Dec. 31. Gage heights about May 17 to Dec. 31 affected by back water from temporary dam constructed about 400 feet below the station to form a boating and swimming pool. The gage 

heights during most of the period May 17 to Oct. 2 were between 8 and 10 feet, and are omitted, since frequeut changes in the dam render them useless as an index of the discharge. There was relatively little 

back water Oct. 3 to Dec. 31, and the relation of gage height to discharge was stable. Gage heights Mar. 5 

to 7 determined from hydrograph.

NOTE. Aug. 29, Mr. Beckett (of the Irrigation Investigations, United States Department of Agriculture) 

found river dry at gage. There was about 1 second-foot flowing 300 feet above but this sank into the ground 

before reaching the gage. The water was standing in pools or bed dry Aug. 24 to about Oct. 8 and there 

was little or no flow past the gage.

EAST FORK OF RUSSIAN RIVER NEAR UKIAH, CAL.

Location. At suspension footbridge in the Yokayo grant, about three-fourths of a

mile above junction with Russian River and 3 miles northeast of Ukiah. 

Records available. August 19 to December 31, 1911. 

Drainage area. Not measured. 

Gage. Staff in two sections on left bank, 40 feet below bridge.
228 SUKFACE WATEB SUPPLY, 1911, PAET XI.

Channel. Sand and gravel; shifts during high stages.

Discharge measurements. Made from footbridge above gage and by wading.

Diversions. The Snow Mountain Water & Power Co. diverts water by a tunnel from 

the South Eel for use in power development at Potter Valley. This water enter? 

the East Fork about 14 miles above the station. At low stages regulation at the 

power plant causes a noticeable fluctuation in the discharge. The daily load 

fluctuates greatly and hence the low-water gage heights are liable to considerable 

error.

KLAMATH RIVER BASIN. 

SPRAGUE RIVER AT CHILOQUIN, OEEG.

Location. In sec. 3, T. 35 S., R. 7 E., at the Southern Pacific Railroad bridge at 

Chiloquin, 200 feet above the junction of Sprague and Williamson rivers.

Records available . July 25, 1911, to December 31, 1911.

G-age. Chain gage on railroad bridge.

Channel. Rocky and probably permanent in main channel. The overflow channel is piled up with gravel and may shift in floods.

Accuracy. Conditions are fair and good results should be obtained.

Diversions. Above the forks of Sprague River there is a considerable amount of 

diversion for irrigation. At present there are no diversions below the forks, but 

a canal is being built to divert water a short distance above this station.

Cooperation. This station is maintained by the United States Reclamation Service 

and the records are worked up and published by the Survey.

UPPER KLAMATH LAKE NEAR KLAMATH FALLS, OREG.

Location. In sec. 30, T. 38 S., R. 9 E., near Klamath Falls, Oreg.

Records available. May 28, 1904, to December 31, 1911.

Drainage area. 3,110 square miles, at the outlet of lake.

Gage. Friez automatic, installed February 16, 1906; referred to level of a staff gage 

installed May 28, 1904. Elevation of zero of staff gage 4,136.13 feet above sea 

level. Gage heights since February 16, 1906, are the means of the daily records 

obtained from the automatic gage.

Diversions. Water is diverted from the lake to the main canal of the Klamath 

project of the United States Reclamation Service.

Fluctuations of lake level. The level of the water surface of Klamath Lake is 

strongly affected by wind. When the wind blows from the south the water may 

be lowered as much as 6 inches near the outlet; when the wind is from the north 

the water surface may be raised 6 inches above its normal level; differences of a 

foot may be noticed within a few hours. If the effect of wind were eliminated, 

the record of lake heights would show much more gradual changes than are indicated by the following tables.

Cooperation. Station maintained by the United States Reclamation Service since 

May, 1909.

a Friez gage out of order, daily gage heights from one reading of staff gage.

NOTE. Daily gage height is mean for 24 hours ending at noon, except as noted. Due to inaccuracies of 

the automatic gage these values may be in error several hundredths of a foot and during the month of September four or five tenths of a foot, but the figures given are believed to be the most nearly correct 

obtainable after a careful study of the automatic gage sheets and the observer's readings on the staff gage.

The lake was frozen at the gage Jan. 1 to Mar. 7 and probably Dec. 18 to 31.

LINK RIVER AT KLAMATH FALLS, OREG.

Location. At the county bridge over Link River at Klamath Falls in sec. 32, T. 38 S., 

R. 9 E., 1J miles below the outlet of Upper Klamath Lake and at the immediate 

head of Lake Ewauna.

Records available. May 15, 1904, to December 31, 1911.

Drainage area. 3,110 square miles.

Gages. Chain gage at the bridge and Friez automatic gage in rapids above bridge. 

The chain gage was removed July 12, 1912, on account of reconstruction of the 

bridge, and reinstalled August 20, 1912, at an arbitrary datum.

Channel. Permanent at both gages; current swift at upper gage, sluggish at lower 

gage. In the 1J miles between Upper Klamath Lake and Lake Ewauna the 

river falls 70 feet.

Discharge measurements. Made at the bridge.

Diversions. Water is diverted in the Keno Canal around the Friez gage. Part of 

this is used to supply the powei plant operated by Moore Bros., and the remainder 

is wasted at a spillway. Both power plant and spillway are located above the 

bridge and below the Friez gage. All the water therefore passes the bridge gage 

and is included in the measurements but does not pass the Friez gage. There 

is no record of amount diverted except a few miscellaneous measurements which 

do not include water wasted from spillway.
240 SURFACE WATER SUPPLY, 1911, PART XI.

Accuracy. The records prior to June 6, 1908, especially the individual daily records 

are not reliable. For longer periods a month or more the determination of 

mean flow can probably be accepted as not greatly in error. This condition is 

accounted for by the effect of wind on the discharge at this station. The gage 

until May 8, 1908, was located at the bridge at the upper end of Lake Ewauna. 

At the outlet of Upper Klamath Lake the river breaks over a rather shallow ledge. 

A strong wind upstream blows the water back from this outlet and at the same 

time increases the height of water on the gage by backing the water in Lake 

Ewauna. Thus we have diminished flow with increased gage height. So great 

is this wind effect that the river has been known to go entirely dry for a few 

hours at a time. When the wind is downstream the flow of Link River is greatly 

increased; but owing to the large surface of Lake Ewauna this increase in flow 

is not shown by the gage heights. In the long run these wind effects are no 

doubt compensating, but little dependence can be placed in the published daily 

records prior to March 7, 1907. On this date an anemometer was installed on the 

bridge and a ship's taffrail log was trailed in the water under the bridge. It was 

hoped that the daily reading from this log would afford some indication of the 

velocities with the anemometer records. Although the records obtained by this 

device were much more reliable during 1907 than previously, even they were not 

all that could be desired. It became evident that owing to the sudden changes 

of the wind complete data could not be obtained without automatic recording 

devices on both the log and anemometer. The method was effective, however, 

in reducing the probable error of the estimates from about 15 per cent to within 

less than 5 per cent. On June 6, 1908, a Friez gage was installed in the rapids, 

where it could be affected only by change in flow, measurements being made at 

the bridge as formerly. In addition to this the automatic gage was damaged by 

logs, and its readings at times affected by log jams. As a result the records published for 1910 and the last part of 1909 are subject to considerable uncertainty 

and no discharges can be computed for 1911.

Cooperation. This station has been maintained by the United States Reclamation 

Service since May, 1909.

KLAMATH RIVER AT KENO, OREG.

Location. At the county bridge over Klamath River at the lower end of the lakes 

and marshes that form the headwaters of the river, in sec. 31, T. 39 S., R. 8 E.

Records available. May 31, 1904, to December 31, 1911.

Drainage area. 3,150 square miles (excluding lower Klamath Lake drainage area).

Gage. Vertical staff nailed to bridge; datum unchanged.

Channel. Immediately below the station the river breaks over a rocky ledge with 

a fall of about 200 feet to the mile. At low stages a growth of aquatic plants clogs 

the channel.

Discharge measurements. Made from a cable 1,000 feet below the gage. No 

measurements made during 1911.

Winter flow. River usually freezes over, but as the water is comparatively deep 

and the ice is not very thick the relation between gage height and discharge is 

not greatly affected.

Accuracy. Relation of gage height to discharge affected by back water caused by 

a growth of aquatic plants in the section and also by the effect of wind on the 

wide expanse of water above the station. A strong upstream wind will blow the 

water back from the outlet and diminish the flow, but as the gage is 1,000 feet 

above the measuring section the gage heights are not always affected to a corresponding degree. On account of lack of measurements no estimates are attempted 

for 1911.

Cooperation. This station has been maintained by the United States Reclamation 

Service since May, 1909.

LOST RIVER AT OLENE, OREG.

Location. At Olene highway bridge, in sec. 14, T. 39 S., K. 10 E.

Records available. May 20, 1907, to December 31, 1911.

Drainage area. 1,290 square miles.

Gage. Vertical staff.

Channel. Permanent; control, a rocky riffle 200 feet below gage.

Discharge measurements. At high stages made from the bridge. At extreme 

low stages by wading at the riffle below the bridge.

Diversions and inflow. A slough connecting Lost River with Klamath River joins 

Lost River 5 miles below the Olene station and Klamath River 2 miles below Lake 

Ew&una. Through this slough it is proposed to divert part of the waters from Lost 

River into Klamath River, and thus reclaim lands bordering Tule Lake. At present, however, the slough has been artificially closed and the flow has been shut off 

for (several years. Before it was diked no water flowed except during high water, 

the direction depending upon whether Klamath or Lost River was the higher. 

There is a small amount of inflow below Olene. One spring was measured April 

14, 1908, giving a discharge of 2.9 second-feet, and during the irrigating season 

there is probably some waste water from irrigation. Nuss Lake is situated half 

a mile from the left bank of Lost River and 1 mile below Olene. It has no surface 

outlet except at flood time, but it is possible that a little water passes underground 

from this lake to the river during the summer months.

Accuracy. The conditions at this station are favorable for good results.

Cooperation. Station maintained by the United States Reclamation Sendee since 

1909.

TITLE LAKE NEAR MERRILL, OREG.

Location. At J. F. Adams's ranch near the mouth of Lost River, in sec. 8, T. 41 S., 

R. HE.

Records available. May 17, 1904, to December 31, 1911.

Gage. Vertical staff fastened to a post driven in the lake bed. Elevation of zero of 

gage, 4,048.21 feet above sea level. When the station was established, the gage 

was referred to a bench mark on a juniper post near by. The bench mark at that 

time was 13.7 feet above the zero of the gage. On October 21, 1904, this elevation 

was verified. On May 11, 1907, the elevation of the same bench mark was found 

to be 12.87 feet above zero of the gage, and was independently verified on June 

11, 1907, and again on November 27, 1908. It appears, therefore, that sometime 

between October, 1904, and May, 1907, gage was raised 0.83 foot. This was 

probably due to the action of ice in the lake, although nothing of this kind has 

been observed since that time. Just when it occurred it has been impossible to 

ascertain, and a graph of the heights has failed to reveal any critical points that 

would account for a sudden change. It is therefore likely that the gage was 

raised a little at a time during the winters of 1905-6 and 1906-7.

Accuracy. Gage heights prior to May, 1907, should not be used for refined studies.

Cooperation. This station has been maintained by the United States Reclamation 

Service since 1909.

Daily gage height, in feet, of Tule Lake near Merrill, Oreg.,for 1911.

MILLER CREEK NEAR LORELLA, OREG.

Location. At highway bridge at Langell Valley, 1 mile east of the Swingle ranch, 

3 miles south of Lorella, Oreg., in sec. 7, T. 40 S., R. 14 E.

Records available. August 10, 1904, to December, 1908; April 1, 1909, to December 31, 1911.

Drainage area. 270 square miles.

Gage. Friez automatic; installed January 30, 1910. Gage was originally established 

August 10, 1904, in sec. 12, T. 39 S., R. 13 E., 9 miles northeast of Lorella, at the 

lower end of Horsefly Valley; removed to the present site, which includes 50 

square miles of drainage area more than that of the upper site, April 1, 1909.

Channel. Rocky; practically permanent.

Discharge measurements. Made from bridge or by wading.

Diversions. Station is just below the diversion dam of a small irrigation flume 

which carries about 1 second-foot of water.

Accuracy. Records somewhat fragmentary up to time Friez gage was installed; 

estimates have been made for all periods of missing observations; determinations 

of total run-off fairly accurate.

Cooperation. Station maintained by United States Reclamation Service since May, 

1909.

NOTE. Daily discharge, 1910-11, determined from a rating curve well defined below 150 second-feet. Discharge interpolated or estimated for days when the gage was not read. These values are based on hydrograph comparisons with the discharge at other near-by stations and are very roughly approximate. They 

are published as a matter of record only and should be used with caution.

COFFEE CREEK AT COFFEE, CAL.

Location. At private highway bridge at Coffee, in the NW. \ sec. 4, T. 37 N., R. 

8 W., in the Shasta National Forest, 5 miles above the junction with Trinity 

River. Boulder Creek enters 400 feet above and Little Boulder Creek 1£ miles 

below the station.

Records available. December 16, 1910, to December 31, 1911.

Drainage area. Not measured.

Gage. Vertical staff fastened near upstream end of bridge pier near right bank.

Channel. Gravel and bowlders; appears permanent.

Discharge measurements. Made from downstream side of bridge at gage and by 

wading.

Artificial control. From April to July, inclusive, and occasionally throughout the 

remainder of the year two dams with automatic or "self-shooting" gates are 

operated about 10 miles above the station. The Nash mine operates a dam having 

a working capacity of about 125 acre-feet. The Holland mine, on the East Fork, 

operates a dam having a working capacity of about 40 acre-feet. At the beginning 

of the season, in April, these dams fill and "shoot" about once an houj; at the end 

of the season, in July, once in 20 or 24 hours. During high water these "floods" 

are hardly perceptible, but late in the season their effect is pronounced. Gage 

readings are made only when the flow is normal.

Accuracy. The gage-height record, on account of the operation of the self-shooting 

dam, is subject to some error. Otherwise the results are good.

Cooperation. Gage-height record and discharge measurements furnished by United 

States Forest Service.

EAST FORK OF TRINITY EIVEE NEAR TRINITY CENTER, CAL.

Location. At highway bridge 2J miles southeast of Trinity Center, in the SW. \ sec. 

15, T. 36 N., R. 7 W., in the Shasta National Forest, one-fourth mile above junction with Trinity River.
266 SURFACE WATER SUPPLY, 1911, PART XI.

Records available. December 15, 1910, to December 31,1911.

Drainage area. Not measured.

Gage. Vertical Btaff on downstream end of left abutment of bridge.

Channel. Gravel and small bowlders; appears permanent. The section at the 

bridge is poor for measurements at low stages because of ponded water.

Discharge measurements. Made from downstream side of bridge or by wading.

Diversions. About 400 acres are irrigated from this stream. The principal diversion is the Trinity Farm & Cattle Co.'s canal, which heads about 4 miles above 

the station. Some water is also used for mining.

Accuracy. Gage record incomplete; otherwise record is good.

Cooperation. Gage-height record and discharge measurements furnished by United 

States Forest Service.

NOTE. Daily discharge 1910-11 determined from a well-defined rating curve. Discharge interpolated 

or estimated for days when the gage was not read. These values are based on hydrograph comparisons 

with the discharge at other nearby stations and are very roughly approximate. They are published as a 

matter of record only and should be used with caution.

268 SURFACE WATEB SUPPLY, 1911, PART XI.

SWIFT CEEEK NEAE TEINITY CENTEE, CAL.

Location. One-fourth mile above junction with North Fork of Swift Creek in E. \

sec. 13, T. 36 N., R. 8 W., in the Shasta National Forest, about 2J miles southwest of

Trinity Center.

Records available. December 17, 1910, to December 31, 1911. 

Drainage area. Not measured. 

Gage. Vertical staff fastened to a cedar tree on left bank 100 feet below foot log.

August 19, 1911, a low-water section was installed at foot log to read same as

original gage but at different datum. 

Channel. Bowlders; rough; probably permanent. 

Discharge measurements. Made from foot log or by wading. 

Accuracy. Individual measurements are subject to considerable error as the bed

of the stream is rough. Rating curve averages all measurements and will give

fair results. Gage-height record is incomplete. 

Cooperation. Gage-height record and discharge measurements furnished by United

States Forest Service.
