SURFACE WATER SUPPLY OF PACIFIC SLOPE BASINS IN OREGON AND LOWER COLUMBIA RIVER BASIN, 1957

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, 1957. 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 13,750 gaging stations in the 48 States and at many others in the Territories of Alaska and Hawaii. On September 30, 1957, the Geological Survey and cooperating 

organizations were maintaining 7,030 gaging stations, including those in Alaska and Hawaii. 

Discharge measurements only were made at many other points in the 1957 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.

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 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 

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,
EXPLANATION OF DATA 3

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 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.

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

EXPLANATION OF DATA 5

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 1957 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 creststage 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
6 SURFACE WATER SUPPLY, 1957, PART 14

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 shiftingcontrol 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. 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 published each year for all reservoirs for which records are published on 

a daily basis, 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.

At many gaging stations water samples are collected from the streams for the purpose of 

making chemical analyses, computing dissolved solids, suspended sediment loads, and 

particle-size distribution, or measuring water temperatures. For most of these samples 

the results are published in an annual series of water-supply papers entitled "Quality of 

Surface Waters of the United States" which is issued in four volumes. In this report 

under "Remarks" a reference is made to quality-of-water records collected at gaging stations on a regular basis and published in the quality-of-water reports. At many other 

gaging stations quality-of-water data are obtained at irregular intervals and published as 

"miscellaneous analyses" in quality-of-water reports; such records are not referred to in 

"Remarks" paragraph in this report. At many gaging stations water temperature is obtained 

also at the time a discharge measurement is made; such temperature readings are not 

reported in the quality-of-water annual 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,

505691 O - 59 - 2
8 SURFACE WATER SUPPLY, 1957, PART 14

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.

PUBLICATIONS

To facilitate publication of the annual series of reports, the area of the United 

States is divided into 14 parts whose boundaries coincide with certain natural drainage 

lines. Formerly, the results of streamflow measurements were published in 14 volumes, one 

for each of the 14 parts. Beginning with the reports for 1951, the records are published 

in 18 volumes, there being 2 volumes each for Parts 1, 2, 3, and 6. The boundaries of the 

various parts are indicated by the following list and the map in figure 2.

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.

A compilation of records for the area covered by this report through September 1950 

has been published as Water-Supply Paper 1318. That report contains a summary of monthly 

and annual discharges for all previously published records as well as some records not 

contained in the annual series of water-supply papers. All records were reexamined and 

revised where warranted. Estimates of discharge were made to fill short gaps whenever 

practical.

The reports listed in the foregoing tables contain the customary records of discharge 

collected during the systematic operation of gaging stations. Detailed information on the 

stage and discharge of many streams during major floods has been included in special 

reports on these floods published by the Geological Survey. The more recent of these
RECORDS OP DISCHARGE COLLECTED BY AGENCIES OTHER THAN THE GEOLOGICAL SURVEY 11 

special reports also contain other pertinent hydrologic information and analyses and 

compilations of data relating to earlier notable floods. The following list gives the

numbers and titles of these reports:

RECORDS OF DISCHARGE COLLECTED BY AGENCIES OTHER THAN THE GEOLOGICAL SURVEY 

The table below contains a list of gaging stations for the area covered by this report, 

at which records of discharge were collected during the water year October 1956 to September 1957 by agencies other than the Geological Survey. The records of these stations are 

not contained in publications of the Geological Survey except as noted. The records on 

many canals and drainage ditches, not here listed, have been collected by the Oregon State 

engineer and the Bureau of Reclamation in connection with the water supply for irrigation

projects.

Records for some earlier years contained in water-supply papers published by the Geological Survey, t Records prior to October 1950, published in WSP 1318. 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.
12 SURFACE WATER SUPPLY, 1957, PART 14

HYDROLOGIC CONDITIONS

Runoff was above median most of the time during the 1957 water year in all or part of 

the area covered by this report. Streamflow was below median only in January throughout 

most of the area as a result of temperatures much lower than average. Some flooding 

occurred in Oregon during December as a result of rains amounting to 6 or 8 inches at 

high elevations, and Chinook winds melting snow up to 7,000 ft elevation. In Oregon, 

new maximum discharges occurred on Dec. 11 at several gaging station sites in the 

Willamette and Umpqua River basins, and near record high discharges occurred on other 

streams in these and Siletz River basin. Some flooding, but less serious, occurred in 

the Rogue River basin in Oregon in February. Runoff remained above median throughout 

most of the area from February until April, when the coastal streams began to recede, 

and was below median until about August. For the two key gaging stations in the area 

covered by this report, a comparison of the monthly discharge during the 1957 water 

year with the median discharge for the 25-year period 1921-45 is shown below.

WALLA WALLA RIVER BASIN 17

Mill Creek at Walla Walla, Wash.

Location. Lat 46°04'40", long 118°16'10", in NE^NW^- sec. 23, T. 7 N., R. 36 E. , on left 

bank, 400 ft downstream from diversion dam and 1.5 miles east of Walla Walla. Prior 

to Jan. 22, 1957, at site 0.8 mile downstream.

Drainage area. 96 sq mi, approximately.

Records available. April 1941 to September 1957.

Gage. Water-stage recorder with artificial control. Altitude of gage is 1,160 ft (from 

topographic map). Prior to Jan. 22, 1957, water-stage recorder at site 0.8 mile downstream at different datum.

Extremes.--Maximum discharge during year, 908 cfs Dec. 11 (gage height, 4.26 ft); no 

flow Oct. 3-5 (seepage probably occurred during period).

1941-57: Maximum discharge, 2,760 cfs Dec. 28, 1945 (gage height, 4.0 ft); maximum gage height, 5.04 ft Jan. 22, 1950, from high-water mark on outside gage; no flow 

on Nov. 2, 1954, Oct. 3-5, 1957, and part of each day Oct. 15, 18-20, Oct. 29 to 

Nov. 1, Nov. 3, 1954.

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

which are poor. Some regulation at diversion dam 400 ft above station where water is 

diverted into Yellowhawk and Garrison Creeks for stock and irrigation. Water is 

diverted 1 mile upstream into Mill Creek Reservoir for flood control with release of 

stored waters after flood into Russell Creek and is also diverted as required to 

replenish losses from seepage and evaporation from small recreation pool maintained 

in the reservoir. City of Walla Walla diverts water for municipal supply several 

miles upstream. Other small diversions above station for irrigation.

Revisions (water years).--WSP 1288: Drainage area. WSP 1348: 1943, 1945-46.

22 WALLA WALLA RIVER BASIN

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-Freewater, 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 3| miles below Milton-Freewater and extends from the vicinity 

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

Bridge, to springs in the vicinity of Dugger Creek. Within this zone are fully threefourths of the springs in the Walla Walla 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 UMATILLA 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 SW^SW^ sec. 31, T. 3 N. , R. 30 E. 

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

R. 29 E., to feed Cold Springs Reservoir of Bureau of Reclamation. 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£ sec. 28, T. 4 N., R. 28 E.; at times it receives water from Cold Springs Reservoir. 

West Division main canal, from left bank of Umatilla River in SW£ sec. 28, T. 5 N. , 

R. 28 E.

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 1957; 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.

Drainage area. 2,290 sq mi, approximately. 

Records available.--October 1903 to September 1957.

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

T929, supplementary adjustment of 1947. Prior to Jan. 26, 1931, staff gage at same 

site and datum.

Average discharge. 30 years (1927-57), 441 cfs (319,300 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, 5,780 cfs Apr. 6 (gage height, 6.25 ft); minimum, 4.0 cfs Oct. 14.

1903-57: 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 poor. 

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).

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

Deschutes River in NWi sec. 16, T. 21 S., R. 8 E., 15 miles northwest of Laplne. 

Drainage area, 254 sq ml, hydrologlc drainage boundary uncertain owing to groundwater exchange. Records available, November 1922 to September 1957. Staff gage read 

once dally Oct. 1-29, Apr. 26 to Sept. 30, occasional readings Nov. 4 to Apr. 2. 

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, 59.480 acre-ft Apr. 27 (elevation, 4,445.81 ft); minimum observed, 

21,130 acre-ft Sept. 28 (elevation, 4,437.03 ft). Maximum contents observed during 

period 1922-57, 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 

elevations 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"10", in gate chamber structure at dam on 

Deschutes River in NEv sec. 7, T. 22 S., R. 9 E., 9 miles west of Laplne. Drainage 

area, 482 sq ml, hydrologlc drainage boundary uncertain owing to ground-water exchange. 

Records available, December 1942, when storage began, to September 1957. Tape gage 

read dally. 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, 201,200 acre-ft Feb. 24 (elevation, 4,337.77 ft); minimum observed, 61,120 acre-ft Sept. 26 (elevation, 4,314.95 ft). Maximum contents observed during period 1942-57, 201,500 acre-ft May 8, 1956 (elevation, 4,337.80 ft); 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). Water 

surface probably cannot be lowered below elevation 4,265.0 ft due to natural flow 

through reservoir. 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. 

Dally elevations and capacity table furnished by Bureau of Reclamation.

Crescent Lake. Lat 43 030'00", long 121°58 I 20", In SW£ sec. 11, T. 24 S., R. 6 E., on outlet works of new dam three-quarters of a mile south of town of Crescent Lake and 

14 miles west of Crescent. Drainage area, 60.7 sq mi, hydrologlc drainage boundary 

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

1957. Tape gage read 1 to 3 times a month. Datum of gage Is 4,825.16 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, 79,970 acre-ft 

Mar. 8 (elevation, 4,843.76 ft); minimum observed, 40,490 acre-ft Sept. 30 (elevation, 

4,833.36 ft). Maximum contents observed during period 1922-57, that of Mar. 8, 1957; 

minimum observed, 9,640 acre-ft Oct. 21, 1931 (elevation, 4,827.91 ft).

Reservoir originally formed by dam of earth and logs completed in 1922, reconstructed as earth-fill dam In 1956. Capacity, 117,200 acre-ft between elevations 4,821.5 

(sill of outlet gate) and 4,853.0 ft (crest of spillway). Dead storage not known; records given herein represent usable contents. Water surface probably cannot be lowered 

below elevation 4,823.4 ft due to natural flow through reservoir. Water Is diverted 

from Deschutes River at Bend by Deschutes County Municipal Improvement District Canal 

for Irrigation near Tumalo.

COLUMBIA RITER MAIN STEM 77

Columbia River at The Dalles, Oreg. 

{Formerly published as Columbia River near The Dalles)

Location. La t 45°36'15", long 121°10'45", in M£ sec. 1, T. IN., R. 13 E., at The Dalles, 

3.2 miles downstream from The Dalles Dam, and at mile 189.3. Prior to Mar. 16, 1957, at 

site 11.7 miles upstream.

Drainage area. 237.000 sq mi, approximately.

Records available. June 1878 to September 1957. Published as "near The Dalles" 1936-56. 

Maximum stage for each year in period 1858 to 1877 from readings of gage at Lower 

Cascades Landing.

Gage.--Water-stage recorder. An auxiliary water-stbrage recorder is located 19.3 miles 

downstream at Hood River. Datum of both gages is at mean sea level, datum of 1929, 

supplementary adjustment of 1947. Prior to Oct. 1, 1931, records based on staff gage 

near present site at datum 46.98 ft higher, supplemented for a few short periods by 

gage-height records at Umatilla and Cascade Locks. Oct. 1, 1931, to May 1, 1935, staff 

gage in entrance to Celilo Canal 11.6 miles upstream at datum 37.71 ft higher. May 2, 

1935, to Mar. 15, 1957, water-stage recorder at site 11.7 miles upstream at datum 

0.12 ft higher.

Average discharge. 79 years, 195,500 cfs (141,500,000 acre-ft per year).

Extremes. Maximum discharge during year, 705,000 efs May 22 (gage height, 94.90 ft); minimum daily, 77,000 cfs Sept. 12.

1858-1957: Maximum discharge, 1,240,000 cfs June 6, 1894 (gage height, 59.6 ft, 

site and datum then in use); minimum observed, 35,000 cfs Jan. 12, 1937 (gage height, 

126.0 ft, site and datum then in use).

Correction.--The maximum discharge for water year 1876 as revised in WSP 1248 should 

not have been made; original figure of 958,000 cfs is correct.

Remarks. Records excellent except those for Mar. 10 to Apr. 30 and June 25 to Sept. 30, 

which are good. Some regulation by Franklin D. Roosevelt Lake above Grande Coulee Dam 

and by reservoirs in Kootenai, Flathead, Pend Oreille, Spokane, Chelan, Yakima, and 

Snake River basins. Many diversions for irrigation above station. Diurnal fluctuations caused by powerplant and gates at McNary Dam.

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

Revisions (water years). WSP 534: 1920(m). WSP 1094: 1894. WSP 1248: 1886, 

1888-89, 1909.

WILLAMETTE RIVER BASIN 125

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

Location. Lat 44°07'25", long 123°17'50", in SE^- sec. 4, T. 17 S., R. 5 W., on left 

bank in canalized river channel, 1,000 ft downstream from Pern 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 1957. Prior to October 1943, published as 

«at Smithfield."

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 

2f miles downstream at datum 11.09 ft lower.

Average discharge. 18 years, 557 cfs, adjusted for diversion to Coyote Creek since 

1943 (403,300 acre-ft per year).

Extremes. Maximum discharge during year, 3,960 cfs Mar. 1; minimum daily, 28 cfs 

Sept. 1, 2.

1939-57: Maximum discharge, 11,500 cfs Jan. 1, 1943 (gage height, 15.12 ft, site 

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

Remarks. Records good except those for periods of shifting control, which are fair. 

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 

2f miles downstream. Pern 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 Pern 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 discharged 

into Pern Ridge Reservoir; drainage area at point of diversion, 21.3 sq mi.

Revisions (water years) . WSP 1248: 1940-41, 1948.

Discharge, In cubic feet per second, water year October 1956 to September 1957

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 1957, 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 

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. 27 years (1907-16, 1939-57), 7,776 cfs (5,630,000 acre-ft per year).

Extremes. Maximum discharge during year, 104,000 cfs Dec. 11 (gage height, 20.50 ft); 

minimum, 627 cfs Aug. 24 (gage height, 1.81 ft).

fair. Plow regulated by Detroit Reservoir (see p. 134). 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 West Stayton; some return 

flow reaches North Santiam River above station. Albany power canal diverts from South 

Santiam River at Lebanon; return flow reaches Willamette River at Albany.

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 1957. Staff gage read once daily. Datum of gage is at mean sea level 

(levels by city of McMinnville). Maximum contents observed during year, 744 acre-ft 

Dec. 9, Apr. 5, 6, 14, 15, 17 (elevation, 835.5 ft); reservoir empty most of time 

Dec. 16 to Mar. 24. Maximum contents observed during period 1951-57, 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 5 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 three siphons is 700 cfs each and 

remaining two. 350 cfs each. 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°06'50", long 121°48'35", in NE£ sec. 27, T. 5 S., 

R. 8 E., in 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 1956 to September 1957. Once-daily readings of 

Bristol pressure gage usually obtained by Three Lynx powerhouse personnel by microwave 

transmission. Datum of gage is at mean sea level (Portland General Electric Co. bench 

mark). Prior to Nov. 26, 1956, staff gage at same site and datum. Maximum contents 

observed during year, 56,580 acre-ft Sept. 21-30 (elevation, 3,183.1 ft); minimum 

observed, 16,010 acre-ft Feb. 24 (elevation, 3,144.5 ft). Maximum contents observed 

during period 1956-57, that of Sept. 21-30, 1957; minimum observed, that of Feb. 24, 

1957.

Reservoir is formed by earth-fill dam with concrete spillway built by Portland 

General Electric Co. Usable storage began May 28, 1956. Capacity, 65,710 acre-ft at 

elevation 3,190.0 ft (normal maximum operating level). Usable capacity, 61,650 acre-ft 

between elevations 3,125.0 (invert of outlet pipe) and 3,190.0 ft (top of taintor 

gates). Storage of 4,060 acre-ft below elevation 3,125.0 ft not normally available for 

release. Water is used for power generation.

October 1913 to September 1917, March 1926 to September 1935, August 1946 to September 

1957. 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.

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

city of Tacoma). Jan. 1, 1912, to Sept. 30, 1917, and Mar. 12, 1926, to Sept. 30, 1935, 

staff, chain, or wire-weight gages within 200 ft of present site at different daturas.

Average discharge . 25 years (1912-17, 1926-35, 1946-57), 5,416 cfs (3,921,000 acre-ft 

per year).

Extremes. Maximum discharge during year, 28,300 cfs Dec. 12 '(gage height, 17.78 ft); minimum daily, 1,050 cfs Sept. 30.

1912-17, 1926-35, 1946-57: 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).

Flood in November 1906 reached a stage of 29.4 ft, datum in use 1913-34 (discharge, 

61,300 cfs).

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

good. Minor diversions for domestic and farm use above station. No regulation.

Revisions ( water years ) . --WSP 769: 1933. WSP 1318: 1913 (annual figures). WSP 1398: 

1914(M), 1916-l7<(M), 1927-28(M), 1930-32(M), 1934-35(M), 1949. See also Records

2.63 ft higher prior to Jan. 1, 1910, at datum 2.11 ft higher Jan. 1, 1910, to

Sept. 30, 1929, and at datum 1.15 ft higher Oct. 1, 1929, to Nov. 1, 1956. 

Average discharge. 52 years, 7,428 cfs (5,378,000 acre-ft per year). 

Extremes. Maximum discharge during year, about 131,000 cfs Dec. 12 (gage height, about

33 ft, from floodmark); minimum daily, 1,100 cfs Aug. 26, 27, Sept. 9-12, 16-18, 23-25.

246 ROGUE RIVER BASIN

South Fork Rogue River near Prospect, Qreg.

Location. Lat 42°42', long 122°23', in NEj sec. 18, T. 33 S., R. 48., on right bank 

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.

Drainage area. 79 sq mi, approximately.

Records available. April 1924 to September 1931, October 1949 to September 1957. Equivalent records for period October 1931 to September 1949 may be obtained from combined 

flow of South Fork .Rogue River above Imnaha Creek near Prospect and Imnaha Creek near 

Prospect.

Gage. Water-stage recorder. Altitude of gage is 3,330 ft (from topographic map). Apr. 26, 

T924, to Sept. 30, 1931, at site an eighth of a mile downstream at different datum.

Average discharge. 15 years (1924-31, 1949-57), 182 cfs (131,800 acre-ft per year).

Extremes. Maximum discharge during year, 2,440 cfs Dec. 11, from river rating curve 

extended from 780 to 2,400 cfs by logarithmic plotting; minimum daily, 84 cfs 

Sept. 22-25.

1924-31, 1949-57; Maximum discharge, 3,180 cfs Dec. 22, 1955 (no flow in canal), 

from rating curve extended above 410 cfs on basis of determination of peak flow over 

dam; minimum daily, about 35 cfs in September 1931, during period of no gage-height 

record.

Remarks. Records fair. All records presented herein include flow in South Fork power 

canal (completed in March 1932), which diverts 500 ft above station and returns water 

to Rogue River above South Fork Rogue River; practically no storage above diversion 

dam.

Cooperation. Electrical-output record for power canal furnished by The California Oregon 

Power Co.

1929 (Bureau of Reclamation bench mark). Prior to Aug. 4, 1955, at sites about half 

a mile upstream at datum 29.9 ft higher.

Average discharge. 12 years (1945-57), 64.3 cfs (46,550 acre-ft per year).

Extremes. Maximum discharge during year, 2,400 cfs Feb. 26 (gage height, 7.15 ft), from 

rating curve extended above 550 cfs on basis of slope-area determination at gage 

height 9.66 ft; minimum, 0.6 cfs Sept. 23, 24, 25.

1940-57: Maximum discharge, 4,610 cfs Dec. 21, 1955 (gage height, 9.66 ft), from 

rating curve extended above 550 cfs on basis of slope-area determination of peak flow; 

minimum, 0.3 cfs Sept. 13, 1944, Aug. 16-27, 1946, Aug. 18, 21, 1950.

Remarks.--Records good except those for periods of shifting control, which are fair. One 

small diversion above station. Prior to 1945, Columbia upper ditch diverted water 

about 2 miles above station, bypassing station.

in files of State engineer.

Gage. Water-stage recorder. Datum of gage is 1,777.22 above mean sea level (Bureau of 

Reclamation benchmark). Prior to Sept. 16, 1947, staff gages at several sites within 

half a mile of present site at various datums. Sept. 16, 1947, to Sept. 19, 1952, 

staff gage at site 280 ft upstream at datum 0.62 ft higher.

Average discharge. 16 years (1941-57), 209 cfs (151,300 acre-ft per year).

Extremes. Maximum discharge during year, 4,470 cfs Feb. 26 (gage height, 6.76 ft); minimum, 27 cfs sometime during period of no gage-height record in August and September 

(gage height, 1.30 ft, from recorded range in stage).

Revisions.--Figures of maximum discharge for the water years 1919-20 have been 

revised to 3,090 cfs Feb. 9, Mar. 2, 1919 (gage height, 7.6 ft), and 2,670 cfs Dec. 24, 

1919 (gage height, 7.0 ft), superseding those published in WSP 514. The maximum discharge for water year 1926 as published in WSP 634 has been found to be in error and 

should not be used.

Remarks.--Regulation by Fish Lake since 1915 (capacity, 8,147 acre-ft). Cascade Canal 

has diverted water from Klamath River basin to Fish Lake since August 1923. Rogue 

River Valley Canal since 1904, in part through the Medford Irrigation District Canal 

since 1922, diverts water for irrigation of about 13,200 acres chiefly in the Bear 

Creek basin below Phoenix. Medford municipal water supply, about 7 cfs, was diverted 

from above station prior to 1927. Other diversions above station for irrigation,total 

about 44 cfs, of which about 2 cfs is used below station.

352 DISCHARGE MEASUREMENTS AT POINTS OTHER THAN GAGING STATIONS

Measurements of streamflow made at points other than regular gaging stations in the 

area covered by this report 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 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 354.
