SURFACE WATER SUPPLY OF PACIFIC SLOPE BASINS IN OREGON AND LOWER COLUMBIA RIVER BASIN, 1951

SCOPE OF WORK

This volume is one of a series of 18 reports presenting measurements of stage, discharge, and content of streams, lakes, and reservoirs in the United States during the water 

year ending September 30, 1951. Since 1888, when the United States Geological Survey first 

studied streamflow in relation to problems of irrigation, similar measurements have been 

made at more than 12,400 gaging stations in the 48 States and at many others in the Terri* 

tories of Alaska and Hawaii. On September 30, 1951, the Geological Survey and cooperating 

organizations were maintaining 6,730 gaging stations, including those in Alaska and Hawaii. 

Miscellaneous discharge measurements were made at many other points in the 1951 water year.

COOPERATION

Many State, municipal, and private organizations have cooperated with the Geological 

Survey in this work by either furnishing or helping to collect data. Organizations that 

supplied data are acknowledged in station descriptions, and organizations that assisted in 

the collection of data through cooperative agreements with the Survey are:

Oregon: State of Oregon, C. E. Strieklin, State engineer; Fish Commission of 

Oregon, A. J. Suomela, Master Fish Warden; and the cities of Corvallis, Eugene, 

MeMinnville, Portland, and Coos Bay-North Bend.

Washington: State Department of Conservation and Development, J. V. Rogers, 

director, succeeded by W. A. Galbraith, and C. J. Bartholet, Supervisor of 

Hydraulics; State Department of Fisheries, Alvin Anderson, director, succeeded 

by R. J. Sehoettler; Walla Walla County; city of Taeoma; and Lewis, Skamania, 

and Wahkiakum County Public Utility Districts.

Assistance in the form of funds or services was given by the Corps of Engineers, Department of the Army, in collecting records published herein for 49 gaging stations in Oregon 

and 8 in Washington,

Assistance was also furnished by the Forest Service, United States Department of Agriculture and the Bureau of Reclamation, United States Department of the Interior. 

The following organizations aided in collecting records:

Oregon: Counties of Crook, Desehutes, 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: Pacific Power & Light Co.

DIVISION OF WORK

The stream gaging was done 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 stations in the several States were collected and prepared for 

publication under the supervision of the district engineers at the offices listed below. 

The records were reviewed and the manuscript prepared for publication under the direction 

of B. J. Peterson, chief, Annual Reports Section.

State District office Address

Washington................... Tacoma....................... 207 Federal Building.

a/ The work was done in collaboration with C. E. Stricklin, State engineer.

Information of a more detailed nature than that published for most of the gaging stat^ons given in this report is on file In the district offices listed above. Provisional 

records of discharge prior to publication, and other unpublished data concerning the 

gaging station records may usually be obtained from the district office.

DEFINITION OF TERMS AND ABBREVIATIONS

The terms of streamflow and other hydrologic data, as used in this report, are defined 

as follows:

Cubic foot per second (cfs) 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.

Cubic feet per second per square mile (cfsm) is the average number of cubic feet of 

water flowing per second from each square mile of area drained, assuming that the runoff 

is distributed uniformly in 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. The term is used 

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

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 relation to storage for 

irrigation.

Cfs-day is the volume of water represented by a flow of 1 cubic foot per second 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 the relation between gage height and the amount of water 

flowing in a channel, expressed as volume per unit of time.

Control designates a feature downstream from the gage that determines the stage-discharge relation at the gage. This feature may be a natural constriction of the channel, 

a long reach of the channel, or an artificial structure.

Contents is the volume of water in a reservoir. Unless otherwise indicated, volume is 

computed on the basis of a level pool and does not include bank storage.

The drainage area of a stream at a specified location Is that area, measured in a horizontal plane, which Is so enclosed by a topographic divide that direct surface runoff frcm 

precipitation normally would drain by gravity into the river above the specified point. 

Figures of drainage area given herein include all closed basins, or noncontributing areas, 

within the area unless otherwise noted.
SURFACE WATER SUPPLY, 1951, PART 14 3 

HEW DOWNSTREAM ORDER OF LISTING GAGING STATIONS

Beginning with the series of reports for the water year ending September 30, 1951, the 

order of listing gaging-station records has been changed. In this report, in a downstream 

direction along the main stem all stations on a tributary entering above a main-stem station 

are listed before that station. If a tributary enters between two main-stem stations, it is 

listed between them. A similar order is followed in listing stations on first rank, second 

rank, and other ranks of tributaries. To indicate the rank of any tributary on which a 

gaging station is situated and the stream to which it is immediately tributary, each indention in the listing of gaging stations in the table of contents of this report represents 

one rank. This new downstream order and system of indention show which gaging stations are 

on tributaries between any two stations on a main stem and the rank of the tributary on 

which each gaging station is situated.

The order of listing used before the publication of the 1951 report listed first all 

stations on the main stem from headwaters toward mouth, then all stations on the uppermost 

tributary to the main stem from the tributary's source to mouth, and then all stations from 

source to mouth of the uppermost tributary to the tributary.

EXPLANATION OF DATA

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

of discharge. In addition,observations of factors affecting the stage-discharge relation, 

weather records, and other information are used to supplement base data in determining the 

daily flow. The records, of stage are obtained either from direct readings on a nonrecording gage oj- from a water-stage recorder that gives a continuous record of fluctuations. 

Measurements of discharge are made with a current meter by the general methods adopted 

by the Geological Survey on the basis of experience in stream gaging since 1888. These 

methods are described in Water-Supply Paper 888 and are also outlined in standard textbooks on the measurement of stream discharge. Typical structures in use at gaging stations 

are shown in figure 1.

Rating tables giving the discharge for any stage are prepared from stage-discharge 

relation curves defined by discharge measurements. If extensions to the rating curves 

are necessary to define the extremes of discharge, they are made on the basis of indirect 

measurements of peak discharge (such as slope-area or contracted-opening measurements, 

computation of flow over dams or weirs, and by other methods), velocity-area studies, and 

logarithmic plotting. 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. If the stage-discharge relation for a station is 

temporarily changed by the presence of aquatic growth or debris on the control, the daily 

mean discharge is computed by what is essentially the shifting-control methcl.

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

reservoirs, tributary streams, or other sources. This necessitates the use of the slope 

method in which the slope or fall in a reach of the stream ia a factor in determining

EXPLANATION OF DATA 5

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 stagedischarge relation is affected by changing stage. If so, 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, and it becomes 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 other stations in the same or nearby basins. If the 

stage-discharge relation is affected by ice, this information is given in a note to the 

table. No mention is made of occasional days of ice effect if the degree of accuracy of 

daily records is not changed.

The data herein presented generally comprise a description of the station, a skeleton 

rating table, and a table showing the daily discharge and monthly and yearly discharge and 

runoff of the stream.

The description of the station gives the location, drainage area, records available, 

type and history of gages, average discharge, extremes of discharge, general remarks, and 

notations of revisions of the previously published record. The location of the gaging 

station and the drainage area are obtained from the most accurate maps available. River 

mileage, given under "Location" for some stations, is that determined and used by the Corps 

of Engineers unless otherwise noted. Under "Gage" are given the type of gage currently in 

use and the datum of the present gage above mean sea level, and a condensed history of the 

types of gages, locations, and daturas of previous gages for which discharge records are 

generally equivalent to those at the present site. Under "Average discharge" is given the 

average discharge for the number of years indicated. It is not given for stations having 

fewer than five 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, a crest-stage indicator, or a nonrecording gage read at the time of the crest. If the maximum gage height did not occur 

at the same time as the maximum discharge, it is given separately. Information pertaining 

to the accuracy of the records and conditions which affect the natural flow at the gaging 

station is given under "Remarks."

Previously published records of some stations have been found to be in error on the 

basis of data or information later obtained. 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 description of all stations for which revised records have been published. 

Listed therein are all the reports in which revisions have been published, each followed 

by the water years for which figures are revised in that report. In listing the report
6 SURFACE WATER SUPPLY, 1951, PART 14

number, "W" means water-supply paper. In listing the water years only one number 13 

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

1933. If no daily, monthly, or annual figures of discharge are concerned 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 cubic feet per second 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 cubic feet 

per second 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.

Skeleton rating tables are published for all stations except those at which the daily 

discharge for the greater part of the open-water period was determined by the shiftingcontrol method, the slope method, or other special methods involving an equivalent adjustment to the gage height of more than one-tenth foot.

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

sudden or rapid fluctuation, the daily 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 once-daily readings of the gage, or to the mean of twice-daily 

readings, or to 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 description.

In the table of daily discharge, the values for the maximum day and the minimum day for 

each month are underlined. If the value is repeated, it is underlined only on the first 

day of its occurrence.

In the monthly summary below the daily table, the line headed "Total" gives the sum of 

the daily values; it is the total cfs-days for the month. The line headed "Mean" gives 

the average flow in cubic feet per second during the month. Runoff for the month may be 

expressed in cubic feet per second per square mile (line headed "Cfsm"), or in inches (line 

headed "In."), or in acre-feet (line headed "Ac-ft"). Values for cubic feet per second per 

square mile and runoff, in inches, are omitted if the drainage area includes large noncontributing areas, or if the average annual rainfall over the drainage basin is usually less 

than 20 inches.

In the yearly summary below the monthly summary, the values of maximum are the maximum 

daily discharges, not the momentary discharges when the water was at crest stage. Likewise, the minimums in this summary are the minimum daily discharges.
ACCURACY OP FIELD DATA AND COMPUTED RESULTS 7

Peak discharges and the times of their occurrence and corresponding gage heights of 

most stations are listed below the table of daily and monthly discharge. 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.

Footnotes to the table of daily discharge indicate periods when discharge was computed 

or estimated by unusual or special methods during periods of no gage-height record and ice 

effect, or by other effects that reduce the degree of accuracy of the records. Days on 

which discharge measurements were made are indicated by asterisk and footnote unless they 

were made at frequent regular intervals, in which instance the general frequency of discharge measurements is given under "Remarks" in the station description.

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 the reservoir are published, 

but it is omitted from succeeding reports.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of streamflow data depends primarily on (1) the stability 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 discharge, and interpretation of records.

The station description states the degree of 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 nearly accurate than the daily records.

Runoff at some stations, as indicated by the monthly mean, may vary widely from natural 

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

evaporation due to artificial causes, or to other factors. For such stations, values of 

cubic feet per second per square mile and runoff, in inches, are not published unless 

storage or diversion records are included to indicate the extent of the regulation or diversion, or unless satisfactory adjustments can be made for changes in contents of 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 it is so stated. 

Even at those stations where adjustments are made, large errors in computed runoff may 

occur when relatively large negative adjustments are made or when evaporation is large in 

comparison with the observed discharge.

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 actually show the water supply available at the stations for further development, 

because water must first be supplied to existing irrigation systems.

The records at most of the stations discussed in these reports extend over many 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 are listed in the same order as the 

streams and gaging stations in the body of the report. An index of the records obtained 

before 1904 has been published in Water-Supply Paper 119.

Each of the reports on the surface-water supply for the year 1939 (Water-Supply Paper 

884 for the Pacific slope basins in Oregon and lower Columbia River basin) contains, for 

the area included in that report, a summary of yearly discharge at gaging stations at 

which 10 or more complete years of record had been collected. These summaries were reprinted separately.

Reports also 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 may have been revised), as well as some records not contained in the 

annual series of water-supply papers. The following table lists reports of this type for

HYDROLOGIC CONDITIONS

Streamflow during the 1951 water year was well above normal In most of the Pacific 

slope basins in Oregon and lower Columbia River basin. Above normal runoff persisted for 

most of the year over most of the area except that streams draining low elevations were 

reported below normal during the months of May and June. Floods In southwestern Oregon In 

October and November 1950 are described In Water-Supply Paper 1137-E. For two key stations

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 If miles above mouth of Umatilla River (no record of monthly diversion during 1951).

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 Pendleton 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 1951; records for some of the canals published separately prior 

to 1926.

DESCHUTES RIVER BASIN 

Reservoirs in Deschutes River basin above Bend, Oreg.

65

Crane Prairie Reservoir. Lat 43°45'20", long. 121°46'50", on control structure at dam on 

Deschutes River in NW£ sec. 16, T. 21 S., R. 8 E., 15 miles northwest of Lapine. Drainage area, 254 sq mi (revised), hydrologic drainage boundary uncertain owing to groundwater exchange. Records available, November 1922 to September 1951. Staff gage read 

once daily except Nov. 18 to Apr. 24, when occasional readings were made. Datum of gage 

is 4,400.0 ft above mean sea level (levels by Bureau of Reclamation). Maximum contents 

observed during year, 58,280 acre-ft May 7-9, 11 (elevation, 4,445.58 ft); minimum, 

29,170 acre-ft Dec. 11 (elevation, 4,439.14 ft). Maximum contents observed during 

period 1922-51, 60,500 acre-ft June 5-7, 1943 (elevation, 4,446.0 ft); no usable contents at times.

Reservoir is formed by earth dam completed by North Canal Co. in 1922; 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-ft between elevation 

4,424 ft (lip of fish screen structure) and 4,445 ft (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.

Wickiup Reservoir.--Lat 43°41'10", long. 121°41'10", in gate chamber structure at dam on 

Deschutes River in NE£ sec. 7, T. 22 S., R. 9 E., 9 miles west of Lapine. Drainage 

area, 482 sq mi, hydrologic drainage boundary uncertain owing to ground-water exchange. 

Records available, December 1942, when storage began, to September 1951. Tape gage 

read daily. Datum of gage is at mean sea level (levels by Bureau of Reclamation). Maximum contents observed during year, 188,800 acre-ft Apr. 17 (elevation, 4,336.64 ft); minimum observed, 18,470 acre-ft Sept. 30 (elevation, 4,293.40 ft). Maximum contents 

observed during period 1942-51, that of Apr. 17, 1951; minimum observed since reservoir 

first filled in March 1949, 13,720 acre-ft Sept. 29, 1949 (elevation, 4,289.67 ft).

Reservoir is formed by rock-faced earth-fill dam completed by Bureau of Reclamation 

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

elevations 4,265.0 ft (no storage) and 4,336.0 ft (crest of spillway, with earth soft 

plug to elevation 4,339.0 ft). Natural flow passing through reservoir when outlet 

gates are open prevents withdrawal of storage below elevation 4,265.0 ft. Sill of 

trash rack structure elevation 4,259.75 ft. Water is diverted from Deschutes River at 

Bend and issued for irrigation of lands near Madras. Daily elevations and capacity 

table furnished by Bureau of Reclamation.

Crescent Lake.--Lat 43°30iOO", long. 121°58'20", in sec. 11, T. 24 S., R. 6 E., at center 

of fish screen 250 ft south of dam, and 14 miles west of Crescent. Drainage area, 60.7 

sq mi (revised), hydrologic drainage boundary uncertain owing to ground-water exchange. 

Records available, August 1922 to September 1951. Staff gage read about once each 

week; also staff gage at head of spillway of dam used occasionally. Datum of gage is 

4,826.0 ft above mean sea level (levels by Deschutes County Municipal Improvement 

District); gage readings have been reduced to elevations above mean sea level. Maximum contents observed during year, 54,860 acre-ft Dec. 10 (elevation, 4,841.0 ft); minimum observed, 42,220 acre-ft Oct. 1 (elevation, 4,837.68 ft). Maximum contents observed 

during period 1922-51, 72,460 acre-ft July 15, 1923 (elevation, 4,845.55 ft); minimum 

observed, 9,640 acre-ft Oct. 21, 1931 (elevation, 4,828.75 ft).

Reservoir is formed by dam of earth and logs, completed and storage begun in 1922. 

Capacity, 86,050 acre-ft between elevations 4,826 ft (sill of outlet gate) and 4,849 

ft (crest of spillway). Dead storage not known; records given herein represent usable 

contents. Water is diverted from Deschutes River at Bend and used by Deschutes County 

Municipal Improvement District for irrigation near Tumalo.

from present site at different datum.

Average discharge. 39 years (1906-18, 1919-20, 1925-51), 103 cfs.

Extremes.--Maximum discharge during year, 586 cfs Nov. 1; minimum, 65 cfs Oct. 1, 2.

 T906-51: Maximum gage height, about 8.75 ft (over top of gage), Nov. 22, 1909, site 

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

time, 1,130 cfs Dec. 2, 1941 (gage height, 3.33 ft); minimum, 19 cfs Dec. 6, 1922.

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

which are poor. A canal near mouth of Pole Creek, a tributary above station, diverts 

entire flow of that creek for irrigation of lands near Sisters.

Rating tables, water year 1950-51, except periods of ice effect (gage

height, in feet, and discharge, in cubic feet per second)

Waldo Lake Outlet near Oakridge, Oreg.

Location. Lat 43°46'00", long. 122°03'10", in NW£ sec. 7, T. 21 S., R. 6 E., on right bank 

on artificial outlet channel of Waldo Lake, 20 miles east of Oakridge.

Drainage area.--30 sq ml, approximately.

Records available.--October 1936 to September 1951.

Gage.. Water-stage recorder and sharp-crested weir. Altitude of gage is 5,410 ft (from 

topographic map).

Average discharge.--15 years, 30.6 cfs.

Extremes. Maximum discharge during year, 125 cfs Jan. 23 (gage height, 2.66 ft); maximum 

gage height, 2.85 ft sometime from Jan. 29 to Feb. 15 (backwater from tree); no flow 

Sept. 16-30.

curve extended above 90 cfs; no flow at times.

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

3 cfs, 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, 8.0 cfs measured on Aug. 23, 1951.

Records available. October 1942 to September 1951.

Gage. Water-stage recorder. Datum of gage is at mean sea level (surveys by Corps of 

Engineers).

Extremes.--Maximum contents during year, 30,720 acre-ft May 24 (elevation, 788.92 ft); minimum, about 580 acre-ft Nov. 13 (elevation, about 738.2 ft), from graph based on records 

of inflow and outflow.

1942-51: Maximum contents, 34,750 acre-ft May 3, 1949 (elevation, 792.42 ft); minimum since first filling, that of Nov. 13, 1950.

Remarks.--Reservoir is formed by earth-fill dam with concrete spillway completed by Corps 

bT~Engineers in 1942; storage began Oct. 31, 1942 (slight pondage at times in water 

year 1941-42, when inflow temporarily exceeded 2,600 cfs, capacity of outlets). Capacity, 33,090 acre-ft between elevations 719.0 ft (outlet conduit) and 791.0 ft (crest 

of spillway). Dead storage negligible. Reservoir used for flood control and improvement of navigation below Albany. Daily contents computed from reservoir elevation at 

12 p.m.

WILLAMETTE RIVER BASM 157

Long Tom River below Fern Ridge Dam, near Smithfield, Oreg.

Location. Lat 44°07'25", long. 123°18<00", in NW£ sec. 4, T. 17 S., R. 5 W., on left bank 

in canalized river channel 1,000 ft downstream from Fern Ridge Dam, which impounds 

runoff of Long Tom River and Coyote Creek, and 2-| miles south of Smithfield.

Drainage area.--252 sq mi.

Records available. August 1939 to September 1951. Prior to October 1943, published as "at Smithfi'el'd."

Gage.--Water-stage recorder and masonry control. Datum of gage is 332.00 ft above mean 

sea level, datum of 1929 (levels by Corps of Engineers). Prior to Oct. 1, 1943, at 

site 2\ miles downstream at different datum.

Average discharge.--12 years, 524 cfs (adjusted for diversion to Coyote Creek since 1943).

Extremes (not Including diversion to Coyote Creek).--Maximum discharge during year, 3,510 

cfs Nov. 22 (gage height, 6.83 ft); minimum daily, 22 cfs Apr. 17.

1943-51: Maximum discharge, 4,500 cfs (gage height, 7.33 ft), from rating curve 

extended above 1,400 cfs on basis of former curve defined to 3,000 cfs; no flow part of 

June 11, 12, 1944.

Remarks. Records of flow in river channel, good; records of diversion to Coyote Creek, 

poor. A few small diversions above station; several cubic feet per second diverted 

around station to Coyote Creek channel through 24-inch concrete pipe 600 ft long, several hundred feet upstream, record of which is based on daily staff-gage readings and 

occasional measurements. Fern Ridge Dam, 1,000 ft above station, was completed in 

1941. and has regulated flow since Nov 13, 1941 (see preceding page). Monthly discharge not adjusted for storage or release from Fern Ridge Dam as evaporation from Reservoir at times exceeds natural flow and diversions.

Note. Backwater from debris July 26 to Aug. 30.
WILLAMETTE RIVER BASIN 175

Santiam River at Jefferson, Oreg.

Location. Lat 44°42'55", long. 123°00'40" , in SE^ sec. 11, T. 10 3., R. 3 W. , on right bank 

350 ft upstream from railroad bridge at Jefferson, 2 miles downstream from confluence of 

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

Drainage area. 1,790 sq mi, approximately.

Records available. October 1905 to June 1906 (gage heights and discharge measurements only), 

October 1907 to September 1916, and October 1939 to September 1951 in reports of Geological Survey. Gage-height records collected at same site since April 1904 are contained 

in reports of United States Weather Bureau.

Gage.--Water-stage recorder. Datum of gage is 199.63 ft above mean sea level, datum of 

T929. Oct. 8, 1905, to June 30, 1906, Oct. 1, 1907, to May 14, 1908, July 1, 1914, to 

Sept. 30, 1916, Oct. 1, 1939, to Sept. 21, 1940, staff gage at site 350 ft downstream, 

and May 15, 1908, to June 30, 1914, staff gage at site 150 ft downstream, all at datum 

3.00 ft higher.

Average discharge. 21 years (1907-16, 1939-51), 7,549 cfs.

Kxtremes.--Maximum discharge during year, 92,200 cfs Nov. 2 (gage height, 19.88 ft); minimum, 555 cfs Sept. 22, 23 (gage height, 2.15 ft).

1905-6, 1907-16, 1939-51: Maximum discharge observed, 161,000 cfs Nov. 22, 1909 

(gage height, 18.2 ft, from floodmark, site and datum then in use; corresponding gage 

height at present site, 23.0 ft from curve of relation), 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 cfs; minimum observed, 260 cfs Aug. 15-22, Aug. 24 to Sept. 2, 

1940 (gage height, -1.00 ft, site and datum then in use).

Maximum discharge known, about 202,000 cfs Nov. 21, 1921 (gage height, 19.5 ft at 

railroad bridge 350 ft downstream, site and datum in use prior to Oct. 1, 1940; corresponding gage height at present site, 24.4 ft from curve of relation).

Remarks.--Records excellent. Salem Canal diverts from North Santiam River at Stayton for 

Irrigation 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 Weat 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.

WILLAMETTE RIVER BASIN 179

Willamette River at Salem, Oreg.

Location.--La t 44°56'40", long. 123°02i30", in SW£ sec. 22, T. 7 S., R. 3 W., on right 

bank 300 ft upstream from Center Street bridge at Salem and at mile 85.1.

Drainage area.--7,280 sq mi, approximately.

Records available.--October 1909 to December 1916, October 1927 to September 1951. Gageheight records collected at about the same site since 1892 are contained in reports of 

United States Weather Bureau.

e.--Water-stage recorder. Datum of gage is 113.61 ft above mean sea level, datum of 

~929. Oct. 1, 1909, to Dec. 31, 1916, staff gage at site half a mile upstream at about 

present datum. Oct. 1, 1927, to Nov. 26, 1934, staff gage at Center Street bridge at 

present datum.

Average discharge.--31 years, 22,700 cfs.

Extremes.--Maximum discharge during year, 159,000 cfs Nov. 1 (gage height, 21.10 ft); min- 

 imum, 3,960 cfs Sept. 24 (gage height, -3.82 ft).

1909-16, 1927-51: Maximum discharge observed, 315,000 cfs Nov. 25, 1909 (gage 

height, 30.5 ft); minimum, 2,470 cfs Aug. 27, 1940 (gage height, -4.45 ft).

Maximum discharge known, 500,000 cfs Dec. 4, 1861 (gage height, about 39 ft), from 

rating curve extended above 250,000 cfs in 1916. Flood of Feb. 5, 1890, reached a 

stage of 37.1 ft. Flood of Jan. 8, 1923, was measured at 344,000 cfs, at or very close 

to peak (gage height, 30.35 ft).

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

fair. Many small diversions for irrigation above station; part of flow of Salem Canal, 

which diverts water from North Santiam River, returns to Willamette River below station, 

through Mill Creek at Salem. Flow regulated at times by Cottage Grove, Fern Ridge and 

Dorena Reservoirs (see pp. 128, 131, 156). Records of chemical analyses and water temperatures for the water year 1951 are given in Water-Supply Paper 1200.

WILLAMETTE RIVER BASIN 185 

Haskins Creek near McMinnville, Oreg.

Location.-Lat 45°18'50", long. 123°21'55", in NE^ sec. 13, T. 3 S., R. 6 W. , on left bank

 300 ft upstream from high-water line of McMinnville water-supply reservoir, M(J it 

downstream from Idlewlld Creek, and 11 miles northwest of McMinnville.

Drainage area.--6.7 sq ml, approximately (revised).

Records available.--October 1928 to September 1951 (discontinued).

Gage --Water-stage recorder and wooden control. Altitude of gage is 815 ft above mean sea

 level (by barometer). Prior to Oct. 1, 1930, at datum 1.00 ft higher.

Average discharge. 23 years, 26.4 cfs (adjusted for diversion), revised.

Extremes (not adjusted for diversion).--Maximum discharge during year, 316 cfs Jan. 17

 (gage height, 2.94 ft, from high-water mark); minimum, 0.7 cfs July 22, 23.

1928-51: Maximum discharge, 610 cfs Mar. 31, 1931 (gage height, 4.00 ft, before 

control was built); minimum prior to diversion above station, 1.0 cfs Oct. 8, 1932.

Revisions --The figures of maximum discharge for water years 1932 and 1935 have been 

revised to 285 cfs Jan. 18, 1932, and 226 cfs Mar. 12, 1935 (gage height, 2.45 ft), superseding those published in Water Supply Papers 739 and 794 respectively.

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

 2 cfs, which are fair. Since Sept. 2, 1937, a small amount of water has been diverted 

at a point 800 ft upstream for municipal supply of McMinnville. Actual amount of diversion not known for water years 1938-39, 1948-51. No regulation.

Cooperation.--Water-stage recorder inspected by employees of city of McMinnville.

Revisions. Revised figures of discharge for the water years 1930 and 1931 (complete 

tables) and for scattered periods in water years 1939, 1945-48 (partial tables) are 

given herein. They supersede those published in Water-Supply Papers 709, 724, 884, 

1044, 1064, 1094 and 1124.

UMPQUA RIVER BASIN 265 

Umpqua River near Elkton, Oreg.

Location. Lat 43°35', long. 123°33i, in sec. 8, T. 23 S., R. 7 W. , on right bank 4 miles 

south of Elkton.

Drainage area.--3,680 sq mi, approximately.

Records available.--October 1905 to September 1951 (incomplete prior to November 1908).

Gage.--Staff gage read twice daily. Datum of gage is 91.33 ft above mean sea level, datum 

of 1929. Prior to Jan. 1, 1910, at datum 1.48 ft higher and Jan. 1, 1910 to Sept. 30, 

1929, at datum 0.96 ft higher.

Average discharge.--46 years, 7,177 cfs.

Extremes.--Maximum discharge during year, 208,000 cfs Oct. 30 (gage height, 44.2 ft), from 

rating curve extended above 68,000 cfs on basis of slope-area determination of peak 

flow; minimum, 1,000 cfs Sept. 19, 20.

1906-51: Maximum discharge, that of Oct. 30, 1950; minimum observed, 640 cfs July 

18, 1926 (gage height, 0.71 ft).

Maximum stage known, 45.5 ft sometime in 1861.

Remarks.--Records good except those for periods of doubtful gage-height record of backwater from moss, which are fair. Some diversions for irrigation from streams in South 

Umpqua River basin, but low flow probably only slightly affected. Powerplant at Winchester and manipulation of gates and racks of fish hatchery at Diamond Lake ordinarily do not affect discharge at this station.

Revisions (water years). W 1184: 1927(M), 1938(M), 1943(M), 1946(M).

500 ft downstream from diversion dam and intake of South Fork power canal, an eighth 

of a mile downstream from Imnaha Creek, and 6 miles southeast of Prospect. Records 

include flow of South Pork power canal.

Drainage area. 79 sq mi, approximately.

Records available.--April 1924 to September 1931, October 1949 to September 1951 (includes 

flow of South Fork power canal completed in March 1932). Equivalent records for period 

October 1931 to September 1949'may be obtained from combined flow of South Pork Rogue 

River above Imnaha Creek near Prospect and Imnaha Creek near Prospect.

Gage. Water-stage recorder. Altitude of gage is 3,350 ft (from river-profile map). Apr. 

26, 1924, to Sept. 30, 1931, water-stage recorder at site about an eighth of a mile 

downstream at different datum.

Average discharge.--9 years (1924-31, 1949-51), 157 cfs.

Extremes. Maximum combined discharge of river and canal during year, 1,480 cfs Dec. 7 

(river gage height, 5.43 ft), from rating curve extended above 660 cfs by logarithmic 

plotting; minimum daily, 80 cfs Oct. 23, 24.

1924-31, 1949-51: Maximum discharge, 1,700 cfs Dec. 19, 1929 (gage height, 4.58 ft, 

site and datum then in use), from rating curve extended above 350 cfs by logarithmic 

plotting; maximum gage height, 4.99 ft Nov. 28, 1927, site and datum then in use 

(backwater from logs); minimum discharge, about 35 cfs in September 1931 during period 

of no gage-height record.

Remarks. Records good. Since March 1932 most of low flow diverted by South Fork power 

canal 500 ft above station (see p. 270 ). Practically no storage above diversion dam.

Revisions (water years).--W 1184: 1930(M).

Discharge, In cubic feet per second, water year October 1950 to September 1951

SPRINGS IN THE VULLA WALLA RIVER BASIN, OREG.-WASH. 309

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 Preewater, Oreg., amounts to about 50,000 aore-ft 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.l

The inner zone is 3 to 3i miles downstream from Milton and 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 Bugger Creek. Within this zone are fully 

three-fourths 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 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.

Discharge measurements in cubic feet per second, of springs in Walla Walla River basin, 

Oreg.-Wash., during water year October 1950 to September 1951t
