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, 1956. 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 ,500 gaging stations in the 48 States and at many others in the Territories of Alaska and Hawaii. On September 30, 1956, the Geological Survey and cooperating 

organizations were maintaining 6,910 gaging stations, including those in Alaska and Hawaii. 

Discharge measurements only were made at many other points in the 1956 water year. 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, L. A. Stanley, State engineer, and B. R. Chandler, 

chairman, Oregon State Highway Commission; Fish Commission of Oregon, M. T. Hoy, 

State Fisheries director; and the cities of Eugene, McMinnvllle , 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 

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 43 gaging stations in 

Oregon and 8 in Washington.

Assistance was also furnished by 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., Portland General Electric Co., and Coos-Curry Public Utility District. 

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
2 SURFACE WATER SUPPLY, 1956, PART 14

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 L. A. Stanley, State engineer.

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 if 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, axid 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 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 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.

FIGURE 1. GAGING-STATION STRUCTURES.
EXPLANATION OF 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 1956 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 datums 

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, 1956, 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" gives 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 OF 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 published each year for all reservoirs for which records are published on a daily basis (whether the daily figures are figures of stage or contents) but 

is not published for reservoirs for which only monthly data are given.

Discharge measurements and determinations of peak flows made at sites other than gaging 

stations are listed at the end of each report.

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 persent; "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 aijustments 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.

Note. Records for all stations In Oregon through September 1910 are contained In WSP 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 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

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

Runoff in excess of median occurred during the 1956 water year throughout most of the 

area covered by this report. Streams rose fairly high Nov. 19-20, 26-28, in Oregon and 

Washington, as a result of warm rains on early accumulated snow. A considerable amount 

of snow accumulated during the early part of December and then heavy rains and warm 

weather combined to cause severe flooding Dec. 11-14 in Washington and in both Washington and Oregon Dec. 21-23. Before these high flows had receded much, further heavy rains, 

particularly in the middle part of western Oregon, caused secondary peaks on Dec. 26. 

In the Roseburg area the peak of Dec. 36 was higher at many stations than that of 

Dec. 21-23. Excessive runoff for December carried over into January and further rises 

occurred Jan. 4, 15, and 22 on many streams. The rise on Jan. 4 was almost as high as 

in December on some streams and that of Jan. 15 was more marked in extreme eastern 

Oregon which had largely escaped the flood of December. Runoff was record-high for December and January at a number of gaging stations on major streams in Oregon including 

John Day, Deschutes, Willamette, Rogue, and Umpqua Rivers. Many smaller streams were 

also excessively high during these periods. These floods will be described in a watersupply paper entitled "Floods of December 1955-January 1956 in far western States," now 

in preparation.
HYDROLOGIC CONDITIONS 13

There were some unusual floods from local streams in the Rogue and Umpqua River basins 

of southwestern Oregon during February, although the main streams did not approach the 

stages of December. Moderate floods occurred in north-central and northeastern Oregon 

during the last 10 days in March as a result of snow melt. Runoff was excessive throughout Oregon during May as warm weather and above average rainfall cut deeply into the 

heavy snow pack at high elevations. Several destructive floods from cloud burst-type 

storms occurred during July in Oregon, on July 10 at Mt. Vernon where Beech Creek flows 

into the John Day River and on July 13 on Bridge Creek, a tributary of John Day River. 

The latter was a disastrous storm centered to the north of Mitchell and the greatest 

runoff came down Meyers Canyon about 5 miles downstream from Mitchell, computed as 

54,500 cfs from 12.7 square miles. These two storms will be described in more detail in 

a summary report on floods during 1956.

Ranking of some of the mean monthly runoff figures for two stations in Washington 

indicates that high runoff occurred during much of the year. The rankings are as follows: 

Lewis River near Cougar, December, 3rd; May, 1st; June, 3rd; July, 2nd. Cowlitz River 

at Castle Rock, December, 3rd; May, 1st; June, 5th; July, 5th.

For two key gaging stations in the area covered by this report, a comparison of the 

monthly and yearly mean discharge during the 1956 water year with the median for the 

25-year period 1921-45 is shown in figure 3 below.

R. 37 E., on right bank Just downstream from bridge on State Highway 3E, a quarter 

of a mile southeast of Bolles and 3 miles west of Waitsburg.

Drainage area.--373 sq mi (revised).

Records available. February 1924 to October 1929 (February and March 1929 monthly discharge only, published in State Water-Supply Bulletin 6), April 1951 to September 

1956.

Average discharge . 10 years (1924-29, 1951-56), 222 cfs (160,700 acre-ft per year).

gage. Water-stage recorder. Altitude of gage is 1,150 ft (from topographic map). Prior 

£o Oct. 5, 1929, water-stage recorder at site half a mile upstream at different datum. 

Apr. 1 to May 6, 1951, staff gage at present site and datum.

Extremes. Maximum discharge during year, 3,410 cfs Dec. 12 (gage height, 9.81 ft), from 

rating curve extended above 1,400 cfs on basis of slope-area determination of peak 

flow; minimum, 13 cfs Aug. 13 (gage height, 4.17 ft).

1924-29, 1951-56: Maximum discharge, 4,470'cfs Jan. 13, 1928 (gage height, 7.04ft, 

site and datum then in use); minimum, 1.4 cfs July 30, 1926 (gage height, 0.42 ft, 

site and datum then in use).

Revisions. Figures of maximum discharge for the water years 1952 and 1953 have 

been revised to 3,440 cfs Feb. 2, 1952 (gage height, 9.84 ft) and 3,030 cfs Jan. 18, 

1953 (gage height,9.35 ft), superseding those published in WSP 1248 and 1288, respectively.

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

which are poor. Diurnal fluctuation and some regulation at low flow caused by opertion of flour mill at Waitsburg. Numerous small diversions for municipal and 

domestic use and for irrigation.

22 SPRINGS IN THE WALIA 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 allavial fan.l

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

Nicholas Spring, which is about half a mile east of Walla Walla River £t 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.

32 UMATIUA RIVER BASIN

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 SWtfSWy sec. 31, T. 3 N. , R. 30 E. 

Umatilla project feed canal, from right bank of Umatilla River in SWir 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 headgate of that canal. Maxwell Canal, from right bank of Umatilla River 

in SW-f 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 SWi sec. 28, T. 5 N., R. 

28 E.

Water 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 

March 1926 to September 1956; records for some of the canals published separately prior 

to 1926. Revised figures of discharge for Maxwell Canal (water year 1921) and West 

Division main 'canal (water year 1923) published in WSP 1398.

Gage. Water-stage recorder. Datum of gage is 330.47 ft above mean sea level, datum of 

1929, supplementary adjustment of 1947. Prior to Jan. 26, 1931, staff gage at same 

site and datum.

Average discharge. 29 years (1927-56), 439 cfs (317,800 acre-ft per year). Years prior 

to 1927 not included in computation of average discharge, due to increased diversion 

since 1927.

Extremes. Maximum discharge during year, 5,850 cfs Dec. 23 (gage height, 6.28 ft); minimum, 6.6 cfs Sept. 28, 29.

1903-56: Maximum discharge, 19,600 cfs May 31, 1906 (gage height, 11.0 ft), from 

rating curve extended above 11,000 cfs by logarithmic plotting; no flow at times.

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

fair. Many diversions above station for irrigation of lands above and below station; 

Brownell Canal diverts below station. Diversions since 1908 to Cold Springs Reservoir, 

an off-channel reservoir (capacity, 50,000 acre-ft). Regulation since 1927 by McKay 

Reservoir (see p. 27).

of State engineer; October 1941 to September 1945 (incomplete) in files of State engineer. Published as "above Cable Creek, near Ukiah" 1914-17, 1919-24.

. Water-stage recorder. Datum of gage is 3,588.61 ft above mean sea level (levels 

uy Oregon State Highway Department). May 1, 1914, to June 30, 1924, staff gage and 

Mar. 1, 1932, to July 2, 1940, water stage recorder, at site 1.2 miles downstream at 

different datum.

Average discharge.--22 years (1914-17, 1919-23, 1940-44, 1945-56), 108 efs (78,190 aere-ft 

per year) .

Extremes.--Maximum discharge during year, 2,510 efs May 8 (gage height, 4.90 ft); minimum, 2.6 efs Aug. 23 (gage height, 1.22 ft).

(gage height, 5.20 ft, from floodmark) , from rating curve extended above 740 efs; 

minimum recorded, I efs Aug. 9, 1932 (corrected), June 24 to July 2, 1940.

Revisions.--Figures of maximum discharge for the water years 1916 and 1922 have 

been revised to 1,190 efs Feb. 11, 1916 (gage height, 3.8 ft, observed) and 1,630 efs 

Apr. 21, 1922 (gage height, 4.4 ft, from graph based on gage readings), superseding 

those published in WSP 444 and 554, respectively.

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

which are fair. Diversions for irrigation of 80 acres above station. No appreciable 

regulation.

Revisions.--Revised figures of discharge, in cubic feet per second, for the water years 

 1916, 1920, and 1924, superseding those published in WSP 444, 514, and 594, are given

DESCHUTES RIVER BASIN 59 

Cultus Creek above Crane Prairie Reservoir, near Lapine, Oreg.

Location. Lat 43°49'30", long 121°49'30", in SW£ sec. 19, T. 20 S., R. 8 E. , on left 

bank 1,000 ft upstream from road bridge, three-quarters of a mile downstream from 

Cultus Lake, and 19 miles northwest of Lapine.

Drainage area. 33.2 sq mi, hydrologic drainage boundary uncertain owing to ground-water 

exchange.

Records available.--March to September 1924 (published as "above Crane Prairie, near

Lapine") and October 1949 to September 1956 in reports of Geological Survey. November 

1937 to September 1941 in reports of State engineer (published as Cultus Creek near 

Lapine). October 1941 to September 1949 in files of State engineer. Records for 

October 1923 to February 1924, published in WSP 594, have been found to be unreliable 

and should not be used.

Gage. Water-stage recorder. Altitude of gage is 4,545 ft (by barometer). Mar. 11 to 

Sept. 30, 1924, staff gage at site 100 ft upstream at different datum.

Average discharge.--18 years (1938-56), 23.3 cfs (16,870 acre-ft per year).

Extremes.--Maximum discharge during year, 211 cfs June 2 (gage height, 2.63 ft); minimum, 

0.1 cfs Oct. 1-4.

1924, 1937-56: Maximum discharge, 214 cfs June 1, 1943 (gage height, 2.72 ft); maximum gage height, 2.76 ft June 15, 1950 (backwater from trees); no flow at times.

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

which are poor. No regulation or diversion above station.

Revisions. See Records available.

72 DESCHOTES RIVER BASIN

Reservoirs in Deschutes River basin above Bend, Oreg.

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

Deschutes River in NW-J- sec. 16, T. 21 S., R. 8 E., 15 miles northwest of Lapine. 

Drainage area, 254 sq mi, hydrologic drainage boundary uncertain owing to ground-water 

exchange. Records available, November 1922 to September 1956. Staff gage read once 

daily Oct. 1-31, May 9 to Sept. 30. occasional readings Nov. 4 to May 6. Datum of 

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

readings have been reduced to elevations above mean sea level. Maximum contents 

observed during year, 58,330 acre-ft June 1 (elevation, 4,445.59 ft); minimum observed, 

18,100 acre-ft Oct. 2, 3 (elevation, 4,436.18 ft). Maximum contents observed during 

period 1922-56, 60,500 acre-ft June 5-7, 1943 (elevation, 4,446.0 ft); no usable 

contents at times.

Revisions. Maximum or minimum contents observed for some water years have been

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 (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°41'10M , in gate chamber structure at dam on 

Deschutes River in NEfi- 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 1956. 

Tape gage read daily. Datum of gage is at mean sea level (levels by Bureau of 

Reclamation). Prior to Jan. 15, 1945, staff gages at nearby sites at same datum. 

Maximum contents observed'during year. 201,500 acre-ft May 8 (elevation, 4,337.80 ft); 

minimum observed, 8,680 acre-ft Oct. 1 (elevation, 4,284.90 ft). Maximum contents observed during period 1942-56, that of May 8, 1956; minimum observed since reservoir 

first filled in March 1949, 523 acre-ft Oct. 18, 1952 (elevation, 4,270.86 ft).

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

Reclamation in August 1949. Capacity, 182,100 acre-ft between elevations 4,265.0 (no 

storage) to 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 trashrack structure 

elevation, 4,259.75 ft. Water is diverted from Deschutes River at Bend and is used 

for irrigation of lands near Madras. Daily elevations and capacity table furnished 

by Bureau of Reclamation.

Crescent Lake. Lat 43°30 I 00", long 121°58 I 20", in SW£ sec. 11, T. 24 S., R. 6 E., at 

outlet gate at dam, three-quarters of a mile south of town of Crescent Lake and 

14 miles west of Crescent. Several other gage sites in vicinity used at times during year due to dam reconstruction. Drainage area, 60.7 sq mi, hydrologic drainage 

boundary uncertain owing to ground-water exchange. Records available, August 1922 

to September 1956. Staff gage read about once each week. Various gages at different 

daturas used during water year 1956, but all adjusted to datum 4,825.16 ft (corrected) 

above mean sea level (levels by Bureau of Reclamation); gage readings have been reduced to elevations above mean sea level. Maximum contents observed during year, 

71,760 acre-ft Aug. 22 (elevation, 4,844.53 ft); minimum observed, 24,580 aore-ft 

Oct. 3 (elevation, 4,832.08 ft). Maximum contents observed during period 1922-56, 

72,460 acre-ft July 15-18, 1923, revised (elevation, 4,844.71 ft, corrected): minimum observed, 9,640 acre-ft Oct. 21, 1931 (elevation, 4,827.91 ft, corrected).

Correction.--According to recent levels by Bureau of Reclamation, datum of gage 

as published in former years is in error. Correct datum is 4,825.16 ft above mean 

sea level. All figures of elevation published prior to Oct. 1, 1955, should be decreased by 0.84 ft.

WILLAMETTE RIVER BASIN 117

Salmon Creek near Oakridge, Oreg.

Location. Lat 43"45"20", long 122"23"00", in SW^ sec. 7, T. 21 S., R. 4 E., on right 

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

Drainage area. 117 sq ml, 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 1956. Published as 

Kelsey River near Hazeldell and Salmon Creek near Hazeldell, 1909.

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

of 1929, supplementary adjustment of 1947. Prior to Oct. 1, 1914, staff gages at 

several sites within 3 miles of present site at various datums. Oct. 1, 1914, to 

Oct. 14, 1919, water-stage recorder at site 1 mile downstream at different datum.

Average discharge. 27 years (1913-15, 1917-19, 1933-56), 412 cfs (298,300 acre-ft per 

year).

Extremes Maximum discharge during year 7,640 cfs Dec. 22 (gage height, 8.20 ft); minimum, 160 cfs Oct. 1-3.

1913-19, 1933-56: Maximum discharge, 8,040 cfs Dec. 28, 1945 (gage height, 8.40 ft), 

from rating curve extended above 4,000 cfs by logarithmic plotting; minimum, 63 cfs 

Jan. 8, 1937 (gage height, 0.87 ft).

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

that were built to divert part of outflow from Waldo Lake into Salmon Creek basin 

were not used during year but leakage under control gates has varied, as shown by 

discharge measurements, from 1.7 to 13 cfs during the period 1936-53, and generally 

has increased with time.

upstream from mouth.

Drainage area.--1.310 sq mi, approximately.

Records available. October 1944 to September 1956. Gage-height records collected at 

same site December 1943 to April 1944 are contained in files of U. S. Weather Bureau.

Gage. Water-stage recorder. Datum of gage is 396.32 ft above mean sea level, datum of 

1929, supplementary adjustment of 1947. Prior to Nov. 24, 1944, wire-weight gage at 

same site and datum.

Average discharge.--12 years, 6,243 cfs (4,520,000 acre-ft per year).

Extremes.--Maximum discharge during year, 73,500 cfs Dec. 22 (gage height 16.25 ft) 

from rating curve extended above 40,000 cfs by logarithmic plotting; minimum, 

1,980 cfs Oct. 2 (gage height, 1.51 ft).

1944-56: Maximum discharge, 88,200 cfs Dec. 29, 1945 (gage height, 17.36 ft), from

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, not including Amazon Creek basin.

Records available. August 1939 to September 1956. Prior to October 1943, published as 

"at Smithfield'1 .

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 Sept. 21, 1939, 

staff gage and Sept. 21, 1939, to Sept. 13, 1943, water-stage recorder, at site 

2^ miles downstream at datum 11.09 ft lower.

.ge discharge. 17 years. 566 cfs, adjusted for diversion to Coyote Creek since 1943 

:U9,800 acre-ft per year).

Extremes. Maximum discharge during year, 10,400 cfs Dec. 26; minimum daily, 40 cfs 

July 19.

and datum then in use); minimum daily, 2 cfs Aug. 7, 1941.

Remarks. Records good. A few small diversions above station. Records include diversion 

for irrigation and stockwater to Coyote Creek channel through 24-inch concrete pipe 

600 ft long, record for which is based on daily staff-gage readings and occasional 

measurements. The diversion is several hundred feet upstream and point of return to 

Long Tom River about 2? miles downstream. Fern Ridge Dam, 1,000 ft above station, was 

completed in 1941, and has regulated flow since Nov. 13, 1941 (see preceding page). 

Discharge not adjusted for storage or release from Fern Ridge Dam as evaporation from 

reservoir at times exceeds natural flow and diversions, and beginning in November 1951 

most of flow of Amazon Creek has been diverted-in SE^ sec. 29, T. 17 S., R. 4 W , and

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 1956, in reports 

of Geological Survey. Gage-height records collected at same site since April 1907 are 

contained in reports of U. S. Weather Bureau,

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

1929. Oct. 8, 1905, to June 30, 1906, Oct. 1, 1907, to May 14, 1908, July 1, 1914, to

Haskins Creek Reservoir. La t 45 0 18'40" , long 123°21 I 15", in NW^ sec. 18, T. 3 S., R. 5 W., 

on control tower 250 ft upstream from dam on Haskins Creek and 11 miles northwest of 

McMinnville. Drainage area, 7.1 sq mi, approximately. Records available, October 

1951 to September 1956. Staff gage read once daily. Datum of gage is at mean sea 

level (levels by city of McMinnville). Maximum contents observed during year, 742 acreft Oct. 11 (elevation, 835.4 ft); reservoir empty most of time Nov. 8 to Apr. 16. Maximum contents observed during period 1951-56, 748 acre-ft Nov. 17, 1954 (elevation, 

835.65 ft); reservoir empty most of time during winter months.

Reservoir is formed by earth-fill dam equipped with 3 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 (invert of outlet tunnel) and 835.0 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. Water is used for municipal supply of city of McMinnville.

Timothy Meadows Reservoir.--Lat 45 0 06'50", long 121°48 I 35" , in NE£ sec. 27, T. 5 S., 

R. 8 E., on side of intake structure 350 ft upstream from dam on Oak Grove Fork, 

0.5 mile upstream from Anvil Creek, and 14 miles south of Government Camp. Drainage 

area, 53.5 sq mi. Records available, May to September 1956. Staff gage usually read 

once daily except no readings Saturday and Sunday. Datum of gage is at mean sea level 

(Portland General Electric Co. benchmark). Maximum contents observed during period 

May to September, 37,110 acre-ft Sept. 30 (elevation, 3,166.8 ft); minimum observed,

260 UMPQUA RIVER BASIN

Umpqua River near Elkton, Oreg.

Location. Lat 43°35'10", long 123°33'30", in NW£ sec. 8, T. 23 S., R. 7 W., on right 

bank 3-j miles (revised) South of Elkton and 8 miles upstream from Elk Creek.

Drainage area.--3 .683 sq mi (revised).

Records available. October 1905 to September 1956 (incomplete prior to November 1908).

Gage. Staff gage read twice daily. Datum of gage is 91.57 ft above mean sea level, 

d~atum of 1929, supplementary adjustment of 1947. 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. 51 years, 7,425 cfs (5,375,000 acre-ft per year).

Extremes. Maximum discharge during year, 218,000 cfs Dec. 22 (gage height, 45.6 ft, from 

floodmark); minimum observed, 1,000 cfs Oct. 3,4.

1905-56: Maximum discharge, that of Dec. 22, 1955; minimum observed, 640 cfs 

July 18, 1926 (gage height, 0.71 ft).

Maximum stage known since at least 1861, that of Dec. 22, 1955; flood in 1861 

reached a stage of 45.5 ft, from information by local residents.

Remarks. Records good. Powerplants on North Umpqua River ordinarily do not affect 

discharge at this station. Some diversions for irrigation from streams in South 

Umpqua River basin, but flow probably only slightly affected.

Revisions (water years). WSP 1184: 1927(M), 1938(M), 1943(M), 1946(M)'. Revised figures 

 of discharge, in cubic feet per second, for the water years 1911-13, superseding those

294 DISCHARGE MEASUREMENTS AT POINTS OTHER THAN OAOINO 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 295.
