SURFACE WATER SUPPLY OF PACIFIC SLOPE BASINS IN OREOON AND LOVER COLUMBIA 

RIVER BASIN, 1948

SCOPE OF WORK

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

stage and flow made on streams, lakes, and reservoirs In the United Spates daring the 

water year ending September 30, 1948. The work was begun In 1888 in connection with 

special studies relating to irrigation. Measurements of the flow of streams and of the 

stage and contents of lakes and reservoirs have been made at about 11,370 gaging stations 

In the 48 States and also at many in the Territories of Alaska anj Hawaii. In July 1948, 

5,960 gaging stations, including those in Hawaii, were being maintained by the Geological 

Survey and cooperating organizations. Miscellaneous discharge measurements were made 

during the water year at many other points.

In the execution of the work many State and private organizations have cooperated, 

either by furnishing data or by assisting in collecting data. Cooperation of the first 

kind is acknowledged in connection with the description of each station affected; cooperation of the second kind-is acknowledged, under the heading "Cooperation," In the introductory matter that precedes the gaging-station records in each volmre. In the present 

volume, the section on cooperation of the second kind appears on page 13.

DEFINITION OF TERMS

The units in which stream-flow data are presented in this report end other terms used 

nereln are defined as follows:

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

rate of'discharge of a stream whose channel la 1 square foot In crosr-sectional area and 

whose average velocity is 1 foot per second.

"Second-feet per square mile" Is the average number of cubic fset of water flowing per 

second from each square mile of area drained, on the assumption that the runoff Is distributed uniformly both as regards time and area.

"Runoff in Inches" is the depth to which an area would be covered If all the water 

draining from it in a given period were uniformly distributed on its surface. It Is used 

for comparing runoff with rainfall, which is usually expressed in Inches.

An "acre-foot" is the quantity of water required to cover an acre to the depth of 

1 foot and is equivalent to 43,560 cubic feet. The term Is commonly used in connection 

with storage for irrigation.

"Second-foot-day" is the volume of water represented by a flow of 1 second-foot for 24 

hours. It is equivalent to 86,400 cubic feet, 1.983471 acre-feet, or 646,317 gallons and 

represents a runoff of 0.0372 inch from 1 square mile.

"Stage-discharge relation" is an abbreviation for the term "relation between gage height 

and discharge."

"Control" Is a term used to designate a feature downstream from We gage that deter-- 

mines the stage-discharge relation at the gage. This feature may be a natural section, 

a reach of the channel, or an artificial structure.

2 SURFACE WATER SUPPLY. lt<48, PART 14

"Contents" is a term applied to the volume of water in a reservoir. It is computed on 

the basis of a level pool and does not include bank storage unless otherwise indicated.

EXPLANATION OP DATA

The base data collected at gaging stations consist of records of stage, measurements 

of discharge, and general information used to supplement the records of stage and discharge 

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

direct readings on a nonrecording gage or from a water-stage recorder 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. Typical structures in use at gaging stations are shown in f.'.gure 1.

Rating tables giving the discharge for any stage are prepared from the discharge measurements. The application of the daily mean gage height to those rating tables gives the 

daily mean discharge, from which the monthly and the yearly mean discharge are computed. 

If the stage-discharge relation is subject to change because of frequent or continual 

change in the physical features that form the control, the daily mean discharge Is determined by the "shifting-control method," in which correction factors based on Individual discharge measurements and notes by engineers and observers are used In applying the 

gage heights to the rating tables. At times the stage-discharge relation for a station 

may be temporarily changed by the presence of aquatic growth or debris on the control. 

For such times the dally mean discharge is computed by what Is essentially the "shiftingcontrol" method, described above.

At some gaging stations the stage-discharge relation Is affected by backwater from 

reservoirs, tributary streams, or other sources, which necessitates the use of the "slope 

method," in which the slope or fall In a reach of the stream Is a factor In the determination of discharge. Information requisite for determining the slope or fall Is obtained 

by means of an auxiliary gage set at some distance from the base gage. At some stations 

the stage-discharge relation Is affected by changing stage, and for them the rate of 

change of stage Is used as a factor in the determination of discharge.

At most gaging stations in the northern part of the United States anil at some in the 

mountainous regions of other parts the stage-discharge relation Is affected by ice during 

the winter, which makes it impossible to oompute the discharge In the uiual manner. Discharge for periods of ice effect is computed on the basis of the gage-height record and 

occasional winter discharge measurements, consideration being given to the available Information on temperature and precipitation, notes by gage observers and engineers, and 

comparable records of discharge for stations in the same or nearby basins. For those 

stations at which the stage-discharge relation Is affected by ice, the days included In 

the periods of ice effect either are indicated In the table by symbols referring 'to a 

footnote that states this fact or are given in a general note following the table. The 

days on which discharge measurements were made during or between period^ of Ice effect, 

shortly before the first period, or shortly after the last period are similarly Indicated 

by a footnote.

For most of the gaging stations on streams In the area covered by this report the data 

presented comprise a description of the station, a table showing the dally discharge of

the stream, and a table of monthly and yearly discharge and runoff. Skeleton rating 

tables are published for all stations except those at which the dally discharge for the 

greater part of the year was determined by the shifting-control method, the slope method, 

or other special methods.

The description of the station gives the type of gage, location, drainage area, records 

available, average discharge, extremes of discharge, general remarks, and notations of revisions of previously published record. The location of the gaging station and the drainage area are obtained from the most accurate maps available. Under "Average discharge" Is 

given the average discharge for the number of years Indicated. It is not given for stations having less than 10 complete years of record or for stations where changes in water 

development during the period of record cause the figure to have little significance. 

Under "Extremes" are given the maximum discharge and gage height; the minimum discharge if 

there is little or no regulation; the minimum daily discharge if there is extensive regulation (also the mlniirfum discharge if useful); and the minimum gage height (unless it is 

of no importance). Unless otherwise qualified, the maximum discharge corresponds to the 

crest stage, obtained by use of a water-stage recorder or a nonrecording gage read at the 

time of the crest. Information pertaining to the accuracy of the records and conditions 

which affect the natural flow at the gaging station is given under "Remarks."

For some stations previously published records have been found to be in error on the 

basis of data or Information obtained subsequently. Revisions of such records are usually 

published along with the current records in one of the annual reports. In order to make 

it easier to find such revised records, a paragraph headed "Revisions (water years)" has 

been added to the station description of all stations for which revised records have been 

published. Listed therein are all the reports in which revisions appear, each followed by 

the water years for which figures are revised in that report. In listing the report 

number, W. means Water-Supply Paper. In listing the years, water years are indicated by 

only 1 year, for instance, 1933 stands for the water year October 1, 1932, to September 30, 

1933. If there were no daily, monthly, or annual figures of discharge Involved In the 

revision, that fact is brought out by notations after the year dates as follows: (M) means 

that only the instantaneous maximum discharge was revised; (m) that only the Instantaneous 

minimum was revised; and (P) that only peak discharges were revised. If the drainage area 

has been revised, the report In which the revised figure was first published is given. It 

should be noted that for all stations for which second-feet per square mile and runoff in 

inches are published, a revision of the drainage area necessitates corresponding revision 

of all figures based on the drainage area. Revised figures of second-feet per square mile 

and runoff in inches resulting from a revision of the drainage area only are usually not 

published in the annual series of reports.

For stations equipped with water-stage recorders, except those on streams subject to 

sudden or rapid fluctuation, the table gives the discharge corresponding to the daily mean 

gage height. For stations subject to such fluctuation the daily mean gage height may not 

indicate the true daily mean discharge, which must be obtained by averaging the discharge 

for parts of the day or by using the discharge integrator, an instrument for obtaining the 

daily mean discharge from a continuous gage-height graph and containing as an essential 

element a curve representing the stage-discharge relation at the station. For stations 

equipped with nonrecording gages, the table of daily discharge gives the discharge

corresponding to either once-daily readings of the gage, the mean of twice-daily readings, 

or the mean gage .height determined from gage-height graphs based on gage readings. For 

periods of rapidly changing stage, the daily mean discharge is determined from gage-height 

graphs based on gage readings, the frequency of which is stated in the station descriptior

In the table of monthly discharge the column headed "Second-foot-days" gives the sum 

for each month of the figures given in the table of daily discharge. The column headed 

"Maximum" gives the maximum daily discharge, not the momentary discharge when the water 

surface was at crest stage. Likewise, in the column headed "Minimum" the quantity given 

is the minimum daily discharge. The column headed "Mean" gives the average flow in cubic 

feet per second during the month.

Peak discharges with the times of their occurrence are listed below the table of monthl 

discharge for most stations. All independent peaks above the selected base are given. It 

base discharge, which Is given in parentheses, is selected so that an average of about 

three peaks a year will be presented. Peak discharges are not published for canals, 

ditches, drains, or for any stream for which the peaks are subject to substantial control 

by man.

For most gaging stations on lakes and reservoirs the data presented comprise a description of the station and a monthly summary table of stage and contents. For some reservoirs a table showing daily contents or stage is given. A skeleton table of capacity at 

given stages is usually given in the first report in which data for a station are publishe 

but is omitted from succeeding reports.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of stream-flow data depends primarily on (1) the permanency of the stagedischarge relation or, if the control is unstable,the frequency of discharge measurements 

and (2) the accuracy of observations of stage, measurements of flov, and interpretation of 

records.

The station description gives a statement in regard to the general accuracy of the records. "Excellent" indicates that, in general, the error in the daily records is believed 

to be less than 5 percent; "good," less than 10 percent; "fair," less than 15 percent; and 

"poor," probably more than 15 percent. The records of monthly and yearly mean discharge 

and runoff are, in general, more accurate than the daily records.

Yield at some stations as indicated by monthly means may vary widely from natural yield 

owing to diversion, consumption, regulation by storage, increase or decrease in evaporatio 

due to artificial causes, or other factors. For such stations figures of "second-feet per 

square mile" and "runoff in inches" are not published unless storage or diversion records 

are included Indicating the extent of the regulation or diversion or unless satisfactory 

adjustments can be made for changes in contents or reservoirs or for other changes inclder 

to use and control. Evaporation from a reservoir is not included in the adjustments for 

changes in reservoir contents, unless its inclusion is indicated. Even at those stations 

where adjustments are made, in some instances large errors in computed yields may occur 

when relatively large negative adjustments are applied or when evaporation Is large in 

comparison with the observed discharge. Figures of second-feet per square mile and runoff 

in inches are also omitted if the drainage area includes large none mtrlbuting areas or 11 

the average annual rainfall over the drainage area is less than 20 Inches.
6 SURFACE WATER SUPPLY, 1948, PART 14

Many gaging stations on streams in the irrigated areas of the United States are situated 

above most of the diversions from those streams, and therefore the discharge recorded does 

not show the water supply available for further development, as pricr appropriations below 

the station must first be satisfied.

The table of monthly discharge presents in summary the distribution of the flow past the 

station. The table of daily discharge affords opportunity for more detailed studies of the 

variation In flow. As further observations in each succeeding year may be expected to 

throw new light on data previously published, It should be borne In mind that such data are 

subject to revision In succeeding water-supply papers.

PUBLICATIONS

The results of stream-flow measurements are now published annually in 14 parts, each 

part covering an area whose boundaries coincide with natoral drainage features as Indicated 

below:

PUBLICATIONS

The records at most of the stations discussed In these reports extend over a series of 

years. Miscellaneous measurements at inany points other than regular gaging stations have 

been made each year and are published under "Miscellaneous discharge measurements" at the 

end of each report, the streams and points of measurement listed appearing In the same 

relative order as the streams and gaging stations In the body of the report. An Index of 

the records obtained prior to 1904 has been published In Water-Supply Paper 119.

Each of-the reports on surface water supply for the year 1939, Issued as Water-Supply 

Papers 871 to 884 (see table on p. 8), contains, for the area covered by that report, a 

sunrnary of yearly discharge at gaging stations at which 10 or more complete years of record 

have been collected. These summaries are available also as separate reprints.

Reports have been published that are compilations of records for various areas, usually 

a single State or drainage basin. These reports contain records previously published 

(some of which have been revised), as well as some records not contained In the annual 

series of water-supply papers. The following table gives the numbers and titles of these 

reports, arranged alphabetically, some by States and some by drainage basins.

COOPERATION

In Oregon the work was done under cooperative agreements with the State of Oregon, 

C. E. Strlcklln, State engineer, and the cities of Corvallls, Eugene, McMlnnvllle, and 

Portland. In Washington the work was done under cooperative agreements with the State Department of Conservation and Development, Art Garton, succeeded by F. A. Stewart as director, and C. J. Bartholet, consulting engineer for the department; State Department of 

Fisheries, Mllo Moore, director; Columbia County; and Walla Walla County.

Financial assistance was furnished by the Corps of Engineers for the operation of 39 

gaging stations In Oregon and 15 In Washington.

Financial assistance was also furnished by the Bureau of Reclamation of the United 

States Department of Interior.

Assistance In collecting records was rendered by the following organizations:

Oregon: Counties of Crook, Deschutes, Jackson, Jefferson, Josephine, Klamath, 

and Umatilla; city of Grants Pass; The California Oregon Power Co., California 

Public Utilities, Pacific Power & Light Co., and Portland General Electric Co. 

Washington: Northwestern Electric Co. and Pacific Power & Light Co.

DIVISION OF WORK

The stream-gaging work was conducted by the water resources division of the Geological 

Survey Carl G. Paulsen, chief hydraulic engineer and Joseph V. B. Wells, chief of the 

surface water branch. The data for the gaging stations were collected and prepared for 

publication under supervision of district engineers as follows: In Oregon, G. H. Canfleld 

until Aug. 31, 1948, succeeded by K. N. Philips on Oct. 22, 1948, the vork being done In 

collaboration with C. E. Strlcklln, State engineer; In Washington, F. V. Veatch.

The records were reviewed and the manuscript prepared for publication under the direction of B. J. Peterson, chief, annual reports section.

Drainage area.- 237,000 square miles.

Heeords available.- June 1878 to September 1948. Prior to October 1931, records based 

starr gage at The Dalles, supplemented for a few short periods by gage-height record 

at Umatilla and Cascade Locks. Maximum stage for each year in period 1858 to 1877 f 

readings of gage at Lower Cascades- Landing.

Average discharge.- 70 years, 194,600 second-feet.

Extremes.- Maximum discharge during year, 1,010,000 second-feet May 31 (elevation, 154. 

feet); minimum, 90,400 second-feet Oct. 1 (elevation, 129.63 feet).

1858-1948: Maximum discharge, 1,240,000 second-feet June 6, 1894 (elevation, 106 

feet on gage at The Dalles, 160.1 feet at present site); minimum observed, 35,000 se 

ond-feet Jan. 12, 1937 (elevation, 126.0 feet).

Remarks.- Records excellent except those for July 1 to Sept. 15, which are good. Stora 

and diversions for irrigation are only a small part of tatal runoff. Some regulatio 

by Franklin D. Roosevelt Lake above Grand Coulee Dam during year, the total increase 

contents during the year ending Sept. 30, 1948, being 182,20? acre-feet.

Cooperation.- Recorder inspected and gages read by Corps of Engineers.

34 UMATILLA RIVER BASIN

Principal diversions from Umatilla River between Pendleton and Umatilla, Oreg.

The following canals divert water from Umatilla River between Pendleton and Umatilla: 

Furnish Canal, from right bank of Umatilla River in sec. 36. T. J N., R. 29 E. Umatilla 

project feed canal, from right bank of Umatilla River in SW£ sec. 22, T. 3 N., R. 29 E., 

to feed Cold Springs Reservoir of Bureau of Reclamation. Westerr Land Canal, from left 

bank of Umatilla River in NE£ sec. 21, T. 3 N., R. 29 E.; gage is 1 mile downstream from 

intake. Alien Canal, from right bank of Western Land Canal, half a mile downstream from 

head gate of that canal. Maxwell Canal, from right bank of Umatilla River in SW^ sec. 

28, T. 4 N., R. 28 E.; at times it receives water from Cold Sprlrgs Reservoir. West Div 

sion main canal, from left bank of Umatilla River in SW£ sec. 28, T. 5 N., R. 28 E. 

Brownell Canal, from right bank of Umatilla River, 2 miles below West Division main cana

diversion and ij miles above mouth of Umatilla River.

Water diverted by all these canals is used for irrigation of lands on both sides of 

Umatilla River near and below Echo; except that diverted by West Division main canal, wh 

is applied to land along Columbia River in vicinity of Irrigon.

Several smaller canals also divert water between Pendleton and Umatilla, but no recor 

for them were obtained.

Records of monthly discharge of the canals, published as a group, are available from 

March 1926 to September 1948; records for some of the canals published separately prior 

to 1926.

Extremes.- Maximum discharge during year, 580 second-feet Oct. 16 (gage height, 3.40 

feet); minimum recorded, 32 second-feet Jan. 26, but may have been less during period 

of Ice effect or no gage-height record Jan. 27 to Feb. 10.

1906-48:" Maximum gage height, about 8.75 feet (over top of gage) Nov. 22, 1909, 

site and datum then in use (discharge not determined); maximum discharge recorded 

since that time, 1,130 second-feet Dec. 2, 1941 (gage height, 3.33 feet); minimum, 19

Note.- No gage-height record Oct. 32-27, Nov. 5 to Jan. 6; discharge computed on basis of weat 

records, recorded range in stage, and records for nearby streams inclvding Salmort Creek near Oak 

ridge and Middle Pork Willamette River near Oakridge.
WILLAMETTE RIVER BASIN 117

Salmon Creek near Oakridge, Oreg.

Location.- Water-stage recorder, lat. 43°45', long. 122°23', in SW£ sec. 7, T. 21 S., R. 

4 E. , a quarter of a mile upstream from Slid.e Creek and 4 miles east of Oakridge.

Drainage area^- 117 square miles at cable a quarter of a mile above gage, where all discharge measurements are made.

Records available.- October 1933 to -September 1948. February 1913 to September 1914 at 

site a miles downstream, below Flat Creek; October 1914 to October 1919 at site 1 mile 

downstream.

Average discharge.- 15 years (1933-48), 374 second-feet.

Extremes.- Maximum discharge during year, 4,240 second-feet Jan. 7 (gage height, 6.25 

feet); minimum, 145 second-feet Oct. 1 (gage height, 1.29 feet).

1913-19, 1933-48-. Maximum discharge, 8,040 second-feet (revised) Dec. 28, 1945 (gage 

height, 8.40 feet), from rating carve extended above 4,000 seconcJ-feet by logarithmic 

plotting; minimum, 63 second-feet Jan. 8, 1937 (gage height, 0.87 foot).

Revisions.- The figures of maximum discharge for some water years have been revised 

as shown in the following table. They supersede those shown in the water-supply papers 

indicated.

Remarks - Records good except those for days of no gage-height record, which are fair. No 

regulation. Since 1936 village of Oakridge has diverted water around station in an 

8-inch pipe. Tunnel and control gates that were built to divert part of outflow from 

Waldo Lake into Salmon Creek Basin were not used during year but leakage under control 

gates amounts to about 5 second-feet.

Revisions (water years).- W 794: 1934. W 814: Drainage area. .Revised figures of discharge ror high-water periods in the water years 1935 and 1943 are given herewith. 

They supersede those published in Water-Supply Papers 794 and 9"4.

Remarks.- Records good except those for periods of no gage-height record and those below 11 

second-feet, which are fair. Salem power canal diverts water from North Santiam River 

at Stayton into Mill Creek; some diversions from canal and creek above station for irrigation. Flow diverted for irrigation on left bank between gage and control is not included in record. Diurnal fluctuation caused by changes at head gates and small power 

plants above station.

WILLAMETTE RIVER BASIN

Tualatin River at Farmington, Oreg.

175

Location. - staff gage, lat. 4S°27'00", long. 122°57'00", In SE^ see. 29, T. 1 S., R. 2 W.., 

at highway bridge at Parmlngton, 7} miles southwest of Beaverton. Auxiliary staff gage 

at highway bridge 63 miles downstream, 1 mile northeast of Soholls. Datum of each gage 

is 100.42 feet above mean sea level, datum of 1929. All discharge measurements made at 

Farmington.

Drainage area.- 568 square miles.

Records available.- October 1939 to September 1948.

Extremes.- Maximum discharge observed during year, 11,800 second-feet Jan. 9 (gage height, 

3H.Yb feet); minimum observed, 53 second-feet Sept. 12.

1939-48: Maximum discharge observed, 14,500 second-feet Dec. 20, 1941; maximum gage 

height observed, 33.45 feet Dec. 21, 1941; minimum discharge observed, 28 second-feet 

Sept. 13, 14, 1944.

Maximum stage known, about 37 feet at Farmington and 33.4 feet at gage near Scholls, 

Dec.. 22 or 23, 1933.

Remarks.- Records good. Gages read twice daily. For gage heights above 8 feet, discharge 

computed by using fall, as determined by twice-daily readings of auxiliary gage, as a 

factor. Slight regulation by log ponds and dam below Gaston have little effect at 

this station; considerable pondage between this station and station near Wlllamette. 

Some diversions by pumping for irrigation above station, chiefly at Wapato Lake, near 

Gaston.

182 WILLAMETTE RIVER BASIN

Clackamas River above Three Lynx Creek, Oreg.

Location.- Water-stage recorder, lat. 45°07', long. 122°04', In NE-J sec. 21, T. 5 S., 

6 E. , just downstream from power plant, 500 feet upstream from Three Lynx Creek anc 

miles southeast of Estaoada. Datum of gage Is 1,098 feet ?bove mean sea level (le 1 

by Portland General Electric Co.).

Drainage area.- 488 square miles.

Records available.- October 1911 to December 1913, October 1921 to September 194B.

Average discharge.- 29 years, 1,827 second-feet.

Extremes.- Maximum discharge during year, 32,200 second-feet Jan, 7 (gage height, 14.' 

I'eet), from rating curve extended above 11,000 second-feet; minlmam, 491 second-fe' 

Sept. 8 (gage height, 0.66 foot); minimum daily, 710 second-feet Oct. 1.

1911-13, 1921-48: Maximum discharge, 34,800 second-feet Mar. 31, 1931 (gage he 

15.5 feet), from rating curve extended above 11,000 second-feet; minimum observed, 

second-feet Aug. 10, 16, 1924, Sept. 20, 1936; minimum daily, 536 second-feet Oct. 

1930.

Remarks.- Records excellent except those for periods of no gage-height record and thos 

above 12,000 second-feet, which are fair. Water diverted from Oak Grove Fork is us 

in power plant on Clackamas River just above station. Considerable diurnal fluctu; 

during periods of low flow.

Cooperation.- Water-stage recorder graph and 10 discharge measurements furnished by PC

3 K., 1 mile downstream from head gate at diversion dam and 5 miles southeast of Prospect; electrical-output meter in power plant in Wj sec. 1, T. C3 S., R. 3 E. Datum of 

gage is about 3,357 feet above mean sea level (levels by The Cslifornia Oregon Power 

Co. ) .

Records available.- April 1932 to September 1948.

Average discharge.- 16 years, 106 second-feet.

Extremes.- Maximum daily discharge during year, 159 second-feet Jan. 20; no flow Jan. 8-

1932-48: Maximum daily discharge, 170 second-feet June 18, 1933, Feb. 22, 1936, 

May 14, 1938, Apr. 4, 5, June 16, 1939; no flow at times.

Remarks.- Records good. Daily discharge computed on basis of electrical output of power 

plant below station, the relation "between electrical output and discharge being based 

on discharge measurements. This canal, completed in March 1932, diverts water from 

South Fork Rogue River 200 feet below mouth of Imnaha Creek for use at power plant 

located in W| sec. 1, T. 33 S., R. 3 E., from which water may be wasted into Middle 

Fork Rogue River or mingled with flow of other diversions in Main power canal.

ROGUE RIVER BASIN 231

Middle Fork Rogue River near Prospect, Oreg.

Location.- Water-stage recorder, lat. 42°44', long. 122°24', in NEj sec. 1, T. 33 S., R. 

3 E., 1,000 feet downstream from diversion dam and intake of Middle Fork power canal 

and 4| miles southeast of Prospect. Datum of gage is 2,617 feet above mean sea level 

(levels by The California Oregon Power Co.).

Drainage area.- 57 square miles.

Records available.- May 1925 to September 1948 (include flow of Middle Fork power canal).

Average discharge.- 23 years, 173 second-feet.

Extremes.- Maximum combined discharge of river and canal during year, 1,640 second-feet 

Tan"! 7 (river gage height, 4.2 feet, from floodmark), from rating curve extended above 

1,100 second-feet; minimum daily, 106 second-feet Oct. 5, 6.

1925-48: Maximum discharge, 2,760 second-feet Nov. 29, 1942 (river gage height, 

5.15 feet), from rating curve extended above 1,100 second-feet; minimum, 72 secondfeet Aug. 24 to Sept. 5, 1931.

Remarks.- Records fair except those for periods of no gage-height record, which are poor. 

Hating curve for river only defined to 320 second-feet by measurements and to 1,100 

second-feet by study of increments of discharge when flow in canal was changed. Low 

flow in river controlled since Nov. 19, 1931, by head gates at diversion dam of power 

canal which diverts water around station; practically no storage above diversion dam. 

Records include flow of Middle Fork power canal (see following page).

Cooperation.- Water-stage recorder graph furnished by The California Oregon Power Co. 

Discharge, in second-feet, water year October 1947 to September 1948

SPRINGS IN THE WALLA WALLA RIVER BASIN, OREG.-WASH. 265

Springs in the Walla Walla River Basin, Oreg.-Wash.

Ground-water overflow through many springs on the alluvial fan of the Walla Walla River 

near Milton and Freewater, Oreg., amounts to about 50,000 acre-feet a year. During the 

irrigation season practically all the overflow is used to water crops on land not served 

by diversion from the river. A survey made in 1933 listed 57 springs or spring groups in 

the area, arranged in "inner," "intermediate," and "outer" zones concentric about the apex 

of the alluvial fan. 1

The inner zone is 3 to 3-j miles downstream from Preewater and extends from the vicinity 

of Nicholas Spring, which is about half a mile east of the Walla Walla River at McCoy 

Bridge, to springs in the vicinity of Dugger Creek. Within this zone are fully threefourths of the springs in the Walla Walla Basin. The intermediate and outer zones, each 

of which contains only a few springs, are about 2 miles and 4 miles, respectively, beyond 

the inner zone.

In

basin, discharge measurements of each of the principal springs and measurements of groundwater levels in representative wells have been made and the results published periodically 

since 1932.

Discharge measurements, In second-feet, of springs in Walla Walla River Basin, Oreg.-Wash.,
