SURFACE WATER SUPPLY OF PACIFIC SLOPE BASINS IN OREGON AND LOWER COLUMBIA 

RIVER BASIN, 1949

SCOPE OP WORK

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

stage and flow made on streams, lakea, and reservoirs in the United States during the 

water year ending September 30, 1949. The work wae 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 11,680 gaging stations 

in the 48 States and also at many in the Territories of Alaska and Hawaii. On September 

30, 1949, 6,240 gaging stations, including those in Hawaii and Alaska 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 acknowedged 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 volume. In the present 

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

DEFINITION OP TERMS

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

herein are defined as follows:

"Second-feet11 Is an abbreviation for "cubic feet per" second." A second-foot is the 

rate of discharge of a stream whose channel Is 1 square foot in cross-sectional area and 

whose average velocity Is, 1 foot per second.

"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 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 sscond-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 the gage that determines 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, 1949, PART 14

"Contents" is a term applied to the volume of water in a reservoir. Unless otherwise 

indicated, it is computed on the basis of a level pool and does not include bank storage.

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 figure 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 daily 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 and 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 compute the discharge in the usual 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 periods 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 stable showing the daily 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 daily 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 minimum 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 nonrecordlng 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 cne 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 dally, monthly, or annual figures of discharge involved in the 

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

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

minimum was revised; and (P) that only peak discharges we're 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 necessltatee 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 eubject to 

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

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

indicate the true dally 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 

dally 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 nonrecordlng gages, the table of daily discharge glvee the discharge
ACCURACY OF FIELD DATA AND COMPUTED RESULTS 5

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 dally mean discharge Is determined from gage-height 

graphs based on gage readings, the frequency of which is stated In the station description.

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

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

"Maximum11 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 monthly 

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

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 dally 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 published 

but Is omitted from succeeding reports.

ACCURACY OP 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 flow, 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 leas than 5 percent; "good," less than 10 percent; "fair," less than 15 percent; and 

"poor," probably more than IS 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 evaporation 

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 incident 

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 soate 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 noncontrlbuting areas or if 

the average annual rainfall over the drainage area is less than 20 Inches.
6 SURFACE WATER SUPPLY, 1949, PART 14

Many gaging stations on streams In the Irrigated are.as of the United States are situated 

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

not sh9w the water supply available for further development, as prior 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 records at most of the stations discussed in these reports extend over a series of 

years. Miscellaneous measurements at many 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 

sunraary of yearly discharge at gaging stations at which 10 or more complete yeara 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.

34 UMATILLA RIVER BASIN

Principal diversions from Umati.Ha River between Pendletori 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. 3 N., R. 29 E. Umatilla 

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

to feed Cold Springs Reservoir of Bureau of Reclamation. Western 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-J- sec. 

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

Division 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 canal 

diversion and lj 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, 

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

Several smaller canals also divert water between Fendleton and Umatilla, but no records for them were obtained.

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

March 1926 to September 1949; records for some of the canals published separately prior 

to 1926.

is 4,400.0 feet above mean sea level (Bureau of Reclamation bench mark). Drainage 

area, 244 square miles. Records available, November 1922 to September 1949. Maximum 

contents observed during year, 55,830 acre-feet Sept. 29 (elevation, 4,445.10 feet); 

minimum observed, 25,040 ncre-feet Nov. 23 (elevation, 4,438.08 1'eet). Maximum contents observed during period 1922-49, 60,500 acre-feet June 5-7, 1943 (elevation, - 

4,446.0 feet); no usable contents at times.

Reservoir is formed by earth dam completed by North Canal Co, in 19S2; gates were 

first closed Nov. 22, 1922; reconstructed as rock-faced earth dam with concrete control works by Bureau of Reclamation in 1939-40. Capacity, 55,340 acre-feet between 

elevations 4,424 feet (lip of fish screen structure) and 4,445 feet (crest of spillway). Natural flow passing through reservoir when outlet gates are open prevents 

withdrawal of storage to elevation of sill of gates. Water used for irrigation near 

Bend and Redmond. Gage read once daily except during Winter when occasional headings 

are made.

August 1949. Timber removal-practically complete. Capacity, 182,100 acre-feet 

between elevations 4,265.0 feet (no storage) to 4,336.0 feet (crest of spillway, with 

earth soft plug to elevation 4,339.0 feet). Natural flow passing through reservoir 

when outlet gates are open prevents withdrawal of storage below elevation 4,265.0 

feet. Sill of trash-rack structure elevation, 4,259.75 feet. Water stored is used 

for irrigation near Madras. Gage read once daily. Daily elevations and capacity 

table furnished by Bureau of Reclamation.

Extremes.--Maximum discharge during'year, 474 second-feet June 10; maximum gage height, 

3.56 feet Jan. 5 (backwater from ice); minimum discharge not determined, occurred during 

period of ice effect; minimum daily, 35 second-feet Jan. 6-10, Jan. 12 to Feb. 14.-

1906-49: 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

20 miles east of Oakridge. Altitude of water surface of lake and gage, 5,410 feet

(from topographic map).

Drainage area. 30 square miles.

Records available.--October 1936 to September 1949.

Average discharge. 13 years, 28.1 second-feet.

Extremes.--Maximum discharge during year, 88 second-feet about Dec. 12 (gage height, 2.06 . 

reet, from recorded range in stage); minimum, 0.1 second-foot Sept. 30.

1936-49: Maximum discharge, 144 second-feet Jan. 2, 1943 (gage height, 2.98 feet), 

from rating curve extended above 90 second-feet; no flow at times.

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

At times seiches on Waldo Lake cause rapid changes in stage at gage several times per 

hour. Lake not artificially regulated. Diversion tunnel into head of Black Creek, 

near south end of lake, built about 1914, is not used, but there is leakage past control 

gates, 5.3 second-feet measured on July 20, 1948.

150 WILLAMETTE RIVER BASIN

Santlam River at Jefferson, Oreg. 

Location.--Water-stage recorder, lat. 44°42'50", long. 123°00'40", In SE£ sec. 11, T. 10 S.,

 K'. 3 W., in Jefferson, 350 feet upstream from railroad bridge, 2 miles downstream fron> 

confluence of North Santiam and South Santiam Rivers, and 9 miles upstream from mouth. 

Datum of gage is 199.63 feet above mean sea level, datum of 1929.

Drainage area. 1,790 square miles.

Hecords available.--July 1905 to July 1906 (gage heights only), October 1907 to September

 1916, and October 1939 to September 1949 in reports of Geological Survey. Gage-height 

records collected at same site since April 1904 are contained in reports of U. S. Weather 

Bureau.

Average discharge.--19 years (1907-16, 1939-49), 7,341 second-feet.

Extremes.--Maximum discharge during year, 93,300 second-feet Feb. 18 (gage height, 19.95

 feet); minimum, 596 second-feet Sept. 8. 9 (gage height, 2.51 feet).

1905-6, 1907-16, 1939-49.--Maximum discharge observed, 161,000 second-feet during night 

of Nov. 22, 1909 (gage height, 18.2 feet, site and datum then in use),- from curve of relation between gages based on readings from 1940 to 1945, and rating, curve for gage at 

present site extended above 140,000 second-feet (corresponding gage height at present site, 

23.0 feet, from curve of relation); minimum observed, 260 second-feet Aug. 15-22, Aug. 24 

to Sept. 2, 1940 (gage height, -1.00 foot, site and datum then in use).

Maximum discharge known, about 202,000 second-feet Nov. 21, 1921 (gage height, 19.5 

feet at railroad bridge 350 feet downstream, site and datum in use prior to Oct. 1, 1940; 

corresponding gage height at present site, 24.4 feet from curve of relation). 

Remarks.--Records good. Salem Canal diverts from North Santiam Riv.er at Stayton for irri-

 gation and power use; most of this water reaches Willamette River through Mill Creek at 

Salem. Stayton Canal diverts from North Santiam River at Stayton for irrigation of lands 

near West Stayton; some return flow reaches North Santiam River above station. Albany 

power canal diverts from South Santiam River at Lebanon; return flow reaches Willamette 

River at Albany. No regulation.

Cooperation. Gage height record collected in cooperation with U. S., Weather Bureau.

Revisions (water years).--W 904: Drainage area. W 1094: 1908, 1910, 1912, 1922(M), 1943-.

Average discharge.- '10 years, 356 second-feet.

Extremes.--Maximum discharge during year', 5,140 second-feet Feb. 18 (gage height, 7.67 

1'eet); minimum, 44 second-feet July 6.

1938-49: Maximum discharge, that of Feb. 18, 1949; minimum, 44 second-feet July 13, 

1939, July 6, 1949.

Maximum discharge known, 8,320 second-feet Dec. ?9, 1937, computed by velocity-area 

method on basis of discharge measurement of 7,300 second-feet made that day.

Remarks. Records good except those for periods of ice effect or no gage-height record, 

and those below 100 second-feet, which are fair. Salem power canal diverts water to 

Mill Creek from North Santiam River at Stayton; some diversions for irrigation from 

canal and creek above station. Flow diverted for irrigation on left bank "between gage 

and control is not included in record. Diurnal fluctuations caused by changes at head 

gates and small power plants above station.

WILLAMETTE RIVER BASIN 177

Tualatin River at Farmington, Oreg.

Location.--Staff gage, lat. 45°27'00". long. 122°57'00", in SE£ sec. 29, T. 1 S., R. 2 W., 

at highway bridge at Farmington, 7^ miles southwest of Beaverton. Auxiliary staff gage 

at highway bridge 8\ miles downstream, 1 mile northeast of Scholls. 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 1949.

Average discharge. 10 years, 1,205 second-feet.

Extremes. Maximum discharge observed during year, 17,400 second-feet Feb. 18; maximum 

gage height, 34.5 feet Feb. 18, from graph based on observer's readings; minimum discharge observed, 37 second-feet Sept. 1.

1939-49: Maximum discharge, that of Feb. 18, 1949; maximum gage height, that of 

Feb. 18, 1949; 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 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 Willamette. Some 

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

Gaston.

Discharge, in second-feet, water year October 1948 to September 1949

Dairy Creek at Mountalndale and Gales Creek near Forest Grove, 

b Stage-discharge relation affected by ice.
WILLAMETTE RIVER BASIN 183

Oswego Canal near Oswego, Oreg.

Location. Water-stage recorder, lat. 45°23'30", long. 122°43'10", in NWi sec. 20, T. 2

 S'., R. 1 E., half a mile downstream from point of diversion from Tualatin River, 1 milr 

upstream from Oswego Lake, and 3 miles southwest of Oswego. Datura of gage is 96.50 

feet above mean sea level, datura of 1929. Auxiliary gage at outlet of Oswego Lake for 

determination of backwater effect of lake on stages at canal gage.

Records available.--October 1928 to September 1949. 

Average discharge. 21 years, 67.1 second-feet.

Extremes. Maximum daily discharge during year, 535 second-feet Feb. 20; minimum daily,

 18 second-feet Mar. 14.

1928-49: Maximum discharge, 6,000 second-feet Dec. 23, 1933 (gage height, lo.l 

. feet, site and datum then in use), computed from slope, area, and lake spillway data; 

practically no flow at times.

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

 Oswego Canal diverts water from Tualatin River in NW{ sec. 20, but diversion dam is 

in NE£ sec. 33, about 3 miles downstream. Water used for development of power below 

Oswego Lake and returned to Willamette River at that point.

230 UMPQUA RIVER BASIN

Umpqua River near Elkton, Oreg.

Location.--Staff gage, lat. 43°35', long. 123°33', in sec. 8, T. 23 S., R. 7 W., 4 miles 

south of Elkton. Datum of gage is 91.33 feet above mean sea. level, datum of 1929.

Drainage area.--3,680 square miles.

Kecords available.--October 1905 to September 1949 (incomplete prior to November 1908).

Average discharge. 44 years, 7,066 second-feet.

Extremes. Maximum discharge during year, 109,000 second-feet Dec. 12 (gage height, 29.5 

reet, from floodmark), from rating curve extended above 67,000 second-feet by logarithmic plotting; minimum observed, 1,110 second-feet Sept. 6. 7 (gage "height, 1.36 feet). 

1905-49: Maximum discharge, 172,000 second-feet Feb. 21, 1927, Dec. 31, 1942, from 

rating curve extended above 67,000 second-feet by logarithmic plotting; maximum gage 

height, 41.1 feet Dec. 31, 1942; minimum discharge observed, 640 second-feet July 18, 

1926 (gage height, 0.71 foot).

Maximum stage known, 45.5 feet sometime in 1861.

Remarks.--Records good except those above 70,000 second-feet, which are fair. Gage read 

twice daily. Some diversions for irrigation from streams in South Umpqua River Basin, 

but low flow probably only slightly affected. Power plant at Winchester and manipulation of gates and racks of fish hatchery at Diamond Lake ordinarily do not affect 

discharge at this station.

Middle Fork Rogue River near Prospect, Oreg.

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

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

and 4j 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 1949 (includes flow of Middle Fork power" canal).

Average discharge. 24 years, 174 second-feet.

Extremes.--Maximum combined discharge of river and canal during year, 1,040 second-feet 

May 2 (river gage height, 3.47 feet); minimum daily, 120 second-feet Jan. 25, 26, 

,lan. 31 to Feb. 2.

1925-49: Maximum discharge, 2,760 second-feet Nov. 29, 1942, from rating curve 

extended above 1,100 second-feet; maximum gage height, 5.2 feet Nov. 29, 1942, Dec. 28, 

1945; minimum discharge, 72 second-feet Aug. 24 to Sept. 5, 1931.

Remarks.--Records good. Rating 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.

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

Discharge, in second-feet, water year October 1948 to September 1949

280 HOGUE RIVER BASIN 

Sucker Creek near Holland, Oreg.

Location. Staff gage, lat. 42°09'', long. 123°28', in NE£ sec. 25, T. 39 S., .R..7 W., 

i mile downstream from Grayback Creek and 4.3 miles northeast of Holland. Datum of 

gage is 1.777.84 feet above mean sea level, datum of 1929 (surveys by Bureau of Reclamation) .

Drainage area. 76 square miles.

Records available.--October 1945 to September 1949 in reports of Geological Survey. April 

1940 to August 1941 at site half a mile upstream. September 1941 to September 1945 in 

files of State engineer.

Extremes.--Maximum discharge observed during year, 1,660 second-feet Feb. 22 (gage height, 

5.10 feet); minimum observed, 22 second-feet Sept. 5, 23.

1940-49: Maximum discharge, 5,090 second-feet Jan. 7, 1948 (gage height, 8.3 feet, 

from floodmark), by slope-area method; minimum observed, 19 second-feet Sept. 27, 28,

1947.

Remarks.--Records good except those for periods of doubtful or no gage-height record, and 

those affected by ice, which are poor. Gage read once daily, oftener during periods of 

high water. No regulation. Grayback Canal diverts water from Grayback Creek above 

station for domestic use and Irrigation; most of return flow from this canal enters 

creek above station.

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

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-fe'et 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," "ihterraediate," and "outer" zones concentric about the apex 

of the alluvial fan.I

The inner zone is 3 to 3j 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 Mc9oy 

Bridge, to springs in the vicinity of Dagger 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 alles and 4 miles, respectively, beyond 

the inner zone.

In order to bring about a more effective use of the available water supply through a 

better understanding of the relation between surface- and ground-water supplies in the 

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.
