SURFACE WATER SUPPLY OF PACIFIC SLOPE BASINS IN OREGON AND LOWER COLUMBIA RIVER BASIN, 1955

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, 1955. 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 13,250 gaging stations in the 48 States and at many others in the Territories of Alaska and Hawaii. On September 30, 1955, the Geological Survey and cooperating 

organizations were maintaining 6,860 gaging stations, including those in Alaska and Hawaii. 

Discharge measurements only were made at many other points in the 1955 water year, most of 

which are published at the end of each report. The name of each stream measured at points 

other than gaging stations is not listed in the index to this report. Only the major 

river basins in which measurements were made are listed under the item "Discharge measurements" in the index.

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. Stricklin and L. A. Stanley, State engineers, 

and B. R. Chandler, chairman, Oregon State Highway Commission; Fish Commission of 

Oregon, M. T. Hoy, State Fisheries Director; and the cities of Eugene, McMinnville, 

Portland, and Coos Bay-North Bend.

Washington: State Department of Conservation and Development, W. A. Galbraith, 

director, and M. G. Walker, supervisor of the Division of Water Resources; State 

Department of Fisheries, R. J. Schoettler, director; city of Tacoma; and Lewis 

and Skamania 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 43 gaging stations in Oregon 

and 9 in Washington.

Assistance was also furnished by the Forest Service, United States Department of Agriculture and the Bureau of Reclamation and Bonneville Power Administration, United States 

Department of the Interior.

The following organizations aided in collecting records:

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

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

Light Co., and Portland General Electric Co. 

Washington: Pacific Power & Light Co.

DIVISION OF WORK

The stream gaging work was done by the Water Resources Division of the Geological

Survey, under the direction of personnel shown in the preface. The data for stations in

the several States were collected and prepared for publication in the district offices 

listed below.

State District office Address

Oregon a/.................... Portland.................... 1001 NE. Lloyd Boulevard.

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

a/ The work was done in collaboration with C. E. Strlcklln and L. A. Stanley, State engineers.

Information of a more detailed nature than that published for most of the gaging stations 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 stagedischarge 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 from 

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.

WSP is used as an abbreviation for "Water-Supply Paper" in references to previously 

published reports.

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 was changed. In this report, in a downstream
EXPLANATION OF DATA 3

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 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 or 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 

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

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 dally 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 method.

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 is a factor in determining 

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.

EXPLANATION OP DATA 5

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. Records are published for the water year which begins on October 1 

and ends on September 30. A calendar for the water year 1955 is shown on page IV for 

the purpose of finding the day of the week for any date.

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 "Records available" are given the periods for 

which there are published records generally equivalent to those at present site. 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, locations, and daturas of previous 

gages used during the period of records available. 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). In the first paragraph, the data given are for the complete current water year 

unless otherwise specified. In the second paragraph, the data given are for the periods 

of record within the calendar year dates in the heading (not necessarily those for the 

complete years indicated by the heading dates). Reliable information concerning major 

floods that have occurred outside the period of record are given in the third or last 

paragraph under "Extremes." 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
6 SURFACE WATER SUPPLY, 1955, PART 14

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 water 

years only one number is 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 

shifting-control method, the slope method, or other special methods involving an equivalent adjustment to the gage height of more than one-tenth foot. Skeleton rating tables 

are generally not published for stations on canals.

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 figures for the maximum day and the minimum day 

for each month are underlined. If the figure 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" give the sum of 

the daily figures; 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"). Figures 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 figures of maximum are the maximum daily discharges, not the momentary discharges when the water was at crest stage.
ACCURACY OP FIELD DATA AND COMPUTED RESULTS 7

Likewise, the minimums in this summary are the minimum daily discharges.

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, figures 

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.

Mote. Records for all stations in Oregon through September 1910 are contained in WSF 370, superseding all earlier reports for these stations.

The records at most of the stations discussed in these reports extend over many years. 

Discharge measurements at many points other than regular gaging stations have been made 

each year and are published-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 sepa-

* Records for some earlier years contained in water-supply papers published by the Geological 

Survey.

Note. Records through 1941 collected by the Oregon State engineer (some in cooperation with the 

Bureau of Reclamation of the U. S. Department of the Interior) are contained in bulletins published 

by that officer. (See page 11, "State reports containing compilations of records of discharge.") 

The other records listed in this table have not been published.
HYDROLOGIC CONDITIONS 13

The water year 1955 was characterized by low flows over most of the area covered by this 

report in Oregon, both with regard to volume of flow for the year and the magnitude and 

number of peak flows that occurred. In western Oregon there was, in general, only one 

peak of any magnitude for the year and that occurred on December 30, 31. Most stations in 

the Rogue River basin had no flows above the base for peaks. Western Oregon was slightly 

below median runoff for the year while eastern Oregon was well below median. The area 

covered by this report In Washington ranged from median to slightly above median. Runoff 

ranged from well below median to deficient over most of the area during December, January, 

and February. Runoff remained deficient in the eastern part during March and April. 

John Day River had the lowest February runoff since 1937 and for the Grande Ronde River 

near La Grange, Oreg., it was the lowest February runoff in 45 years of record. Runoff 

ranged from slightly above median to excessiver over most of the area during May to September. For the two key gaging stations in the area covered by this report, a comparison of 

the monthly discharge during the 1955 water year with the median discharge for the 25-year 

period 1921-45 is shown below.

24 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-Preewater, Oreg., amounts to about 50,000 acre-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. 1

The inner zone is 3 to 3i miles below Milton-Preewater and extends from the vicinity of 

Nicholas Spring, which is about half a mile east of 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 River basin. The intermediate and outer zones, each of which 

contains only a few springs, are about 2 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.

UMATILLA RIVER BASIN 31

McKay Creek near Pendleton, Oreg.

Location, Lat 45°36'40", long 118°48'00", in SE^NW-^ sec. 34, T. 2 N., R. 32 E., on right 

bank 35 ft upstream from irrigation diversion dam, a quarter of a mile downstream from 

McKay Dam, and 4 miles south of Pendleton.

Drainage area. 186 sq mi.

Records available. November 1918 to September 1923, October 1924 to September 1955.

Gage. Water-stage recorder and concrete control. Datum of gage is 1,163.71 ft above mean 

sea level (Bureau of Reclamation benchmark). Prior to Apr. 15, 1919, staff gage at site 

2 miles upstream at different datum. Apr. 3, 1919, to Sept. 30, 1923, staff gage at 

site about a quarter of a mile upstream at different datum. Oct. 1, 1924, to Jan. 14, 

1927, staff gage and Jan. 15, 1927, to Nov. 15, 1948, water-stage recorder, at several 

sites within 220 ft of present site, at various datums.

Average discharge. 18 years (1932-43, 1948-55), 88.3 cfs (63,930 acre-ft per year) unadjusted.

Extremes. Maximum discharge during year, 420 cfs Aug. 16 (gage height, 1.58 ft); no flow 

Oct. 1 to about Mar. 31, and less than 1 cfs diverted around station during this period. 

1918-23, 1924-55: Maximum discharge observed, 3,250 cfs Feb. 10, 1921 (gage height, 

4.4 ft, site and datum then in use), from rating curve extended above 1,200 cfs; no flow 

at times.

Remarks. Records good except those below 10 cfs, which are poor. Diversions above station 

for irrigation. Since 1932 records exclude flow in Elder ditch, which diverts up to 

10 cfs around station, for irrigation below station, in summer months, and entire flow 

(seepage only) as stock water at times during winter months. Plow completely regulated 

since 1927 by McKay Reservoir (see preceding,page).

UMATILLA RIVER BASIN 37

Principal diversions from Umatilla River 

between Yoakum and Umatilla gaging stations, Oreg.

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

Furnish Canal, from right bank of Umatilla River In SW^SWtr sec. 31, T. 3 N., R 30 E 

(revised) 'Umatilla project feed canal, from right bank of Umatilla River in SWir sec. 22, 

i. -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 headgate of that canal. Maxwell Canal, from right bank of Umatilla River 

,, r*£, s ? c ' 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 SWfr sec. 28, T. 5 N., R. 

28 E.

TT ?an er diverted by all of 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 Yoakum and Umatilla, but no records 

for them were obtained.

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

!- ar?So September 1955; records for some of the canals published separately prior 

to 1926.

Revisions. Revised figures of discharge, in cubic feet per second, for Maxwell Canal 

near Hermiston ( water year 1921 ) and West Division main canal near Umatilla (water year 

1923), superseding figures published in WSP 534 and 574, respectively, are given herewithbate ' 1

quarter of a mile upstream from Slide Creek and 4 miles east of Oakridge.

Drainage area. 117 sq mi, at cable a quarter of a mile above gage, where all discharge 

measurements are made.

Records available . October to November 1909 (gage heights and one discharge measurement 

only), February 1913 to October 1919, October 1933 to September 1955. Published as 

Kelsey River near Hazeldell, 1909.

£_. Water-stage recorder. Datum of gage is 1,421.83 ft above mean sea level, datum of 

929, supplementary adjustment of 1947. Prior to Oct. 1, 1914, staff gages at several 

sites within 3 miles of present site at various daturas. Oct. 1, 1914, to Oct. 14, 

1919, water-stage recorder at site 1 mile downstream at different datum.

Average discharge . 26 years (1913-15, 1917-19, 1933-55), 403 cfs (291,800 acre-ft per 

year ) .

Extremes. Maximum discharge during year 1,720 cfs June 9 (gage height, 4.18 ft); minimum, 

143 cfs Nov. 10, 11.

1913-19, 1933-55: Maximum discharge, 8,040 cfs Dec. 28, 1945 (gage height, 8.40 ft),

Remarks . --Records excellent. No regulation above station. Since 1936, village of OakrTcIge has diverted water around station in an 8-inch pipe. Tunnel and control 

gates built to divert part of outflow from Waldo Lake into Salmon Creek basin were not 

used during year but leakage under control gates has varied, as shown by discharge measurements, from 1.7 to 13 cfs during the period 1936-53, and generally has increased 

with time.

Records available. November 1953 to September 1955.

Gage. Water-stage recorder. Datum of gage is at mean sea level (levels by Corps of Engineers). Prior to Dec. 5, 1954, elevations are interpolations to nearest foot between 

construction Joints of known elevation spaced 5 ft apart. Elevations Dec. 5, 1954, to 

Feb. 4, 1955, are from staff-gage readings.

Extremes. Maximum contents during year, 448,400 acre-ft June 14 (elevation, 927.23 ft); 

minimum observed, 91,200 acre-ft Dec. 1 (elevation, 811 ft).

1953-55: Maximum contents, that of June 14, 1955; minimum since first filling, that 

of Dec. 1, 1954.

Remarks.-Reservoir is formed by earth-fill dam with concrete gate and spillway section, 

completed in 1954 by Corps of Engineers. Planned storage began in November 1953. Total capacity is 456,000 cfs and usable capacity is 349,400 acre-ft between elevations 

819 ft (proposed lower limit of operation) and 929 ft (top of spillway gates). Reservoir used for fl&od control, improvement of navigation, power generation, pollution 

abatement, and other purposes. Daily contents computed from elevations at 8 a.m., 

Oct. 1 to Dec. 19, Dec. 21, 22, 29 and at 12 p.m. on all other days. Capacity table 

computed by Corps of Engineers. Figures shown herein are for total storage.

158 WILLAMETTE RIVER BASIN

Mill Creek at penitentiary annex, near Salem, Oreg.

Location. Lat 44°52'55", long 122°58'35", in NE£ sec. 18, T. 8 S., R. 2 W., on left bank 

at State penitentiary annex, 2 3/4 miles downstream from Battle Creek, 5 miles southeast of Salem, and 7 miles upstream from mouth.

Drainage area. 104 sq mi.

Records available. October 1940 to September 1955 in reports of Geological Survey. November 1938 to September 1941 in reports of Oregon State engineer.

Gage.--Water-stage recorder. Datum of gage is 231.96 ft above mean sea level, datum of 

1929, supplementary adjustment of 1947.

Average discharge. 16 years (1939-55), 367 cfs (265,700 acre-ft per year).

Extremes. Maximum discharge during year, 1,750 cfs Apr. 12 (gage height, 4.75 ft); minimum, 86 cfs July 3.

1938-55: Maximum discharge, 5,140 cfs Feb. 18, 1949 (gage height, 7.67 ft); minimum, 

44 cfs July 4, 1939, July 6, 1949.

Maximum discharge known, 8,320 cfs Dec. 29, 1937, computed by velocity-area method 

on basis of discharge measurement of 7,300 cfs made that day.

Remarks. Records good except those for periods of shifting control or backwater from 

debris or dike on control, 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. Plow diverted for irrigation on left bank between gage and 

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

and small powerplants above station.

Extremes.--Maximum contents during year, 748 acre-ft Nov. 17 (elevation, 835.65 ft); reservoir empty most of time Nov. 23 to Apr. 18.

1951-55: Maximum contents, that of Nov. 17, 1954; reservoir empty most of-time 

during winter months.

Remarks.--Dam is earth-fill construction, equipped with three siphon spillways, which act 

as overflow weirs until priming occurs (approximately 835.5 ft elevation). Capacity 

of reservoir is 733 acre-ft between elevations 761.5 ft, invert of outlet tunnel 

(about 5 ft in diameter), and 835 ft, crest of siphon spillways. Rated capacity of 

each siphon is 350 cfs. Under normal operation, reservoir is filled in the spring 

(April or May), and drained when fall rains start. There is no planned storage during 

winter months; however, during periods of heavy runoff, inflow may be greater than capacity of outlet tunnel, and there may be some temporary storage.

176 WILLAMETTE RIVER BASIN

Tualatin River at Farmington, Oreg.

Location. Lat 45°27'00", long 122°57'00", in SE^ sec. 29, T. 1 S., R. 2 W., attached to 

upstream side of highway bridge at Farmington, 5-| miles southeast of Hillsboro.

Drainage area. 568 sq mi.

Records available.--October 1939 to September 1955.

Gage. Wire-weight gage read twice daily. Datum of gage is 100.42 ft above mean sea

level, datum of 1929. Prior to Oct. 1, 1940, staff gage at same site at datum 2.00 ft 

higher. Oct. 1, 1940, to Mar. 30, 1955, staff gage at present site and datum. Auxiliary staff gage read twice daily at a highway bridge 6f miles downstream.

Average discharge.--16 years, 1,324 cfs (958,500 acre-ft per year).

Extreme's.--Maximum discharge during year, 4,230 cfs Jan. 4, 5 (gage height, 23.00 ft); 

minimum, 12 cfs Sept. 9, 10.

1939-55: Maximum discharge, 17,400 cfs Feb. 18, 1949; maximum gage height, 34.5 ft 

Feb. 18, 1949, from graph based on gage readings; minimum discharge observed, 6.8 cfs 

Aug. 26, 1951.

Maximum stage known, about 37 ft (present datum) at Farmington and 33.4 ft at gage 

near Scholls, Dec. 22 or 23, 1933.

wHIch are fair. 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.

196 COWLITZ RIVER BASIN

Cowlitz River at Mossyrock, Wash.

Location. Lat 46°33'00", long 122°29'30", in SE£ sec. 1, T. 12 N., R. 2 E., on left bank 

200 ft upstream from Harmony Bridge and 1? miles north of Mossyrock.

Drainage area. 1,170 sq mi, approximately.

Records available.--January to April 1912, November 1912 to June 1913 (fragmentary), October 1913 to September 1917, March 1926 to September 1935, August 1946 to September 

1955. Estimated means October to December 1912 and July to September 1913, published 

in State Water-Supply Bulletin 5, have been found to be unreliable and should not be 

used. Revised estimate of 1913 water year figure only in State Water-Supply Bulle - 

tin 6.

Gage.--Water-stage recorder. Datum of gage is 357.31 ft above mean sea level (levels by 

city of Tacoma). Prior to Sept. 18, 1913, chain gage on Harmony Bridge 200 ft downstream at different datum. Sept. 18, 1913, to Sept. 30, 1917, Mar. 12, 1926, to 

Dec. 10, 1933, staff gage within 100 ft of present site at different datum. Dec. 11, 

1933, to Mar. 8, 1934, stage determined from reference marks on bridge and staff-gage 

readings at various sites just upstream from bridge at different daturas. Mar. 9, 1934, 

to Sept. 30, 1935, wire-weight gage on bridge at different datum.

Average discharge.--23 years (1912-17, 1926-35, 1946-55), 5,334 cfs (3,862,000 acre-ft per 

year).

Extremes. Maximum discharge during year, 26,800 cfs June 11 (gage height, 17.1 ft, from 

recorded range in stage); minimum, 1,290 cfs Sept. 26 (gage height, 3.56 ft).

1912-17, 1926-35, 1946-55: Maximum discharge, 83,500 cfs Dec. 23, 1933 (gage height, 

37.53 ft, average of high-water marks, site and datum then in use), from rating curve 

extended above 20,000 cfs; minimum, 543 cfs Nov. 30, 1952 (gage height, 3.06 ft).

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

as shown in the following table. They supersede figures published in the water-supply 

papers indicated.

272 DISCHARGE MEASUREMENTS AT POINTS OTHER THAN GAGING STATIONS

Measurements of streamflow in the Pacific slope basins in Oregon and lower Columbia 

River basin made at points other than regular gaging stations are given in the following 

table. Most of these measurements were made during periods of base flow when streamflow 

is primarily from ground-water storage. Measurements believed to have been made under 

base-flow conditions are identified by an asterisk (*) to the left of the discharge figure. These measurements when correlated with the simultaneous discharge of a nearby 

stream where continuous records are available will give a picture of the low-flow potentiality of stream. The column headed, "Measured previously" shows the water years in 

which measurements were made at the same, or practically the same, site.

Determinations of peak flow at points other than regular gaging stations are given in 

a separate table on page 274.
