RIVER BASIN, 1950

SCOPE OF WORK

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

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

water year ending September 30, 1950. The work was begun In 1888 in connection with 

special studies relating to irrigation. Measurements of the flow of streams and of the 

stage and contents of lakes and reservoirs have been made at about 12,060 gaging stations 

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

30, 1950, 6,540 gaging stations, Including those In Hawaii and Alaska were being maintained by the Geological Survey and cooperating organizations. Miscellaneous discharge 

measurements were made during, the water year at many other points.

In the execution of the work many State and private organizations have cooperated, 

either by furnishing data or by assisting in collecting data. Cooperation of the first 

kind is acknowedged in connection with the description of each station affected; cooperation of the second kind is acknowledged, under the heading "Cooperation," in the introductory matter that precedes the gaging-station records in each volume. In the present 

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

DEFINITION OF TERMS

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

herein are defined as follows:

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

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

whose average velocity is. 1 foot per second.

"Second-feet per square mile" is the average number of cubic feet of water flowing per 

second from each square mile of area drained, on the assumption that ths runoff is distributed uniformly both as regards time and area.

"Runoff In inches" is the depth to which an area would be covered if all the water 

draining from it In a given period were uniformly distributed on its surface. It is used 

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

An "acre-foot" is the quantity of water required to cover an acre to the depth of 

1 foot and is equivalent to 43,560 cubic feet. The term is commonly used in connection 

with storage for irrigation.

"Second-foot-day" is the volume of water represented by a flow of 1 second-foot for 24 

hours. It Is equivalent to 86,400 cubic feet, 1.983471 acre-feet, or 646,317 gallons and 

represents a runoff of 0.0372 inch from 1 square mile.

"Stage-discharge relation" is an abbreviation for the term "relation between gage height 

and discharge."

"Control" is a term used to designate a feature downstream from the gage that determines the stage-discharge relation at the gage. This feature may be a natural section, 

a reach of the channel, OP an artificial structure.

"Contents" is a term applied to the volume of water in a reservoir, unless otherwise

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

2 SURFACE WATER SUPPLY, 1950, PART 14

."Drainage area" of a stream at a specified location is that area, measured in a horizontal plane, which is enclosed by a topographic divide such that direct surface runoff from 

precipitation normally would drain by gravity into the river basin above the specified 

point. Figures of drainage area given herein include all elosed basins or non-contributing 

areas within the area unless otherwise noted,

EXPLANATION OF DATA

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

of discharge, and general information -used to supplement the records of stage and discharge 

measurements in determining the daily flow. The records of stage are obtained either from 

direct readings on a nonrecording gage or from a water-stage recorder that gives a continuous record of the fluctuations. Measurements of discharge are made with a current 

meter by the general methods outlined in standard textbooks on the measurement of river 

discharge. Typical structures in use at gaging stations are shown in figure 1.

Rating tables giving the discharge for any stage are prepared from the discharge measurements. The application of the daily mean gage height to tho'se rating tables gives the 

daily mean discharge, from which the monthly and the yearly mean discharge are computed. 

If the stage-discharge relation is subject to change because of frequent or continual 

change in the physical features that form the control, the daily mean discharge is determined by the "shifting-control method," in which correction factors based on individual discharge measurements and notes by engineers and observers are used in applying the 

gage heights to the rating tables. At times the stage-discharge relation for a station 

may be temporarily changed by the presence of aquatic growth or debris on the control. 

For such times the daily mean discharge is computed by what is essentially the "shiftingcontrol" method, described above.

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

reservoirs, tributary streams, or other^sources, which necessitates the use of the "slope 

method," in which the slope or fall in a reach of the stream is a factor in the determination of discharge. Information requisite for determining the slope or fall is obtained 

by means of an auxiliary gage set at some distance from the base gage. At some stations 

the stage-discharge relation is affected by changing stage, and for them the rate of 

change of stage is used as a factor in the determination of discharge.

At most gaging stations in the northern part of the United States and at some in the 

mountainous regions of other parts the stage-discharge relation is affected by ice during 

the winter, which makes it impossible to compute the discharge in the usual manner. Discharge for periods of ice effect is computed on the basis of the gage-height record and 

occasional winter discharge measurements, consideration being given to the available information on temperature and precipitation, notes by gage observers and engineers, and 

comparable records of discharge for stations in the same or nearby basins. For those 

stations at which the stage-discharge relation i6 affected by ice, the days included in 

the periods of ice effect either are indicated in the table by symbols referring to a 

footnote that states this fact or are given in a general note following the table. The 

days on which discharge measurements were made during or between periods of ice effect, 

shortly before the first period, or shortly after the last period are similarly indicated

the stream, and a table of monthly and yearly discharge and runoff. Skeleton rating 

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

greater part of the year was determined by the shifting-control method, the slope method, 

or other special methods.

The description of the station gives the type of gage, location, drainage area, records 

available, average discharge, extremes of discharge, general remarks, and notations of revisions of previously published record. The location of the gaging station and the drainage area are obtained from the most accurate maps available. Under "Average discharge" is 

given the average discharge for the number of years indicated. It is not given for stations having less than 10 complete years of record or for stations where changes in water 

development during the period of record cause the figure to have little significance. 

Under "Extremes" are given the maximum discharge and gage height; the minimum discharge if 

there is little or no regulation; the minimum daily discharge if there Is extensive regulation (also tne minimum discharge if useful); and. the minimum gage height (unless it is 

of no Importance). Unless otherwise qualified, the maximum discharge corresponds to the 

crest stage, obtained by use of a water-stage recorder, a crest-stage Indicator, or a nonrecording gage read at the time of the crest. Information pertaining to the accuracy of 

the records and conditions which affect the natural flow at the gaging station is given 

under "Remarks."

For some stations previously published records have been found to be in error on the 

basis of data or information obtained subsequently. Revisions of such records are usually 

published along with the current records in 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 station description of all stations for which revised records have'been 

published. Listed therein are all the reports in which revisions appear, each followed by 

the water years for which figures are revised in that report. In listing the report 

number, W. means Water-Supply Paper. In listing the years, water years are indicated by 

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

1933. If there were no daily, monthly, or annual figures of discharge involved 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 second-feet 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 second-feet per square mile 

and runoff in inches resulting from a revision.of the drainage area only are usually not 

published in the annual series of reports.

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

sudden or rapid fluctuation, the 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
ACCURACY OP FIELD DATA AND COMPUTED RESULTS 5

corresponding to either once-daily readings of the gage, the mean of twice-daily readings, 

or the mean gage .height determined from gage-height graphs based on gage readings. For 

periods of rapidly changing stage, the 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 monthly discharge the column headed "Second-foot-days" gives the sum 

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

"Maximum" gives the maximum daily discharge, not the momentary discharge when the water 

surface was at crest stage. Likewise, in the column headed "Minimum" the quantity given 

is the minimum daily discharge. The column headed "Mean" gives the average flow in cubic 

feet per second during the month.

 Peak discharges with the times of their occurrence are listed below the table of monthly 

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

base discharge, which is given in parentheses, is selected so that an average of about 

three peaks a year will be presented. Peak discharges arts not published for canals, 

ditches, drains, or for any stream' for which the peaks are subject to substantial control 

by man.

For most gaging stations on lakes and reservoirs the data presented comprise a description of the station and a monthly summary table of stage and contents. For some reservoirs a table showing daily contents or stage is given. A skeleton table of capacity at 

given stages is usually given in the first report in which data for a station are published 

but is omitted from succeeding reports.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of stream-flow data depends primarily on (1) the permanency of the stagedischarge relation or, if the control is unstable, the frequency of discharge measurements 

and (2) the accuracy of observations of stage, measurements of flow, and interpretation of 

records.

The station description gives a statement in regard to the general'accuracy of the records. "Excellent" indicates that, in general, the error in the daily records is believed 

to be 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 accurate than the daily records.

Yield at some stations as indicated by monthly means may vary widely from natural yield, 

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

due to artificial causes, or other factors. For such stations figures of "second-feet per 

square mile" and "runoff in inches" are not published unless storage or diversion records 

are included Indicating the extent of the regulation or diversion or unless satisfactory 

adjustments can be made for changes in contents or reservoirs or for other changes incident 

to use and control. Evaporation from a reservoir is not included in the adjustments for 

changes in reservoir contents, unless its inclusion is indicated. Even at those stations 

where adjustments are made, in some instances large errors in computed yields may occur 

when relatively large negative adjustments are applied or when evaporation is large in 

comparison with the observed discharge. Figures of second-feet per square mile and runoff 

in inches are also omitted if the drainage area includes large noncontributing areas or if 

the average annual rainfall over the drainage area is less than 20 inches.
6 SURFACE WATER SUPPLY, 1950, PART 14

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 show the water supply available for further development, as prior appropriations below 

the station must first be satisfied.

The table of monthly discharge presents in summary the distribution of the flow past 

the station. The table of daily discharge affords opportunity for more detailed studies 

of the variation in flow. As further observations in each succeeding year may be expected 

to throw new light on data previously published, it should be borne In mind that such data 

are subject to revision in succeeding water-supply papers.

The records at most of the stations discussed in these reports extend over a series of 

years. Miscellaneous measurements at many points other than regular gaging stations have 

been made each year and are published under "Miscellaneous discharge measurements" at the 

end of each report, the streams and points of,measurement listed appearing in the same 

relative order as the streams and gaging stations in the body of the report. An index of 

the records obtained prior to 1904 has been published in Water-Supply Paper 119.

Each of the reports on surface water supply for the year 1939, issued as Water-Supply 

Papers 871 to 884 (see table on p. 8), contains, for the area covered by that report, a 

summary of yearly discharge at gaging stations at which 10 or more complete years of 

record have been collected. These summaries are available also as separate reprints.

Reports have been published that are compilations of records for various areas, usually 

a single State or drainage basin. These reports contain records previously published 

(some of which have been revised), as well as some records not contained in the annual 

series of water-supply papers. The following table gives the numbers and titles of these 

reports, arranged alphabetically, some by States and some by drainage basins.

34 UMATILLA RIVER BASIN

Principal diversions from Umatilla River between Pendleton and Umatilla, Oreg.

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

Furnish Canal, from right bank of Umatilla River in sec. 36, T. 3 N., R. 29 E. Umatllla 

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 head gate 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. Brownell Canal, from 

right bank of Umatilla River 2 miles below West Division main canal diversion and \\ miles 

above mouth of Umatilla River (no record of monthly diversion during 1950).

Water diverted by all these canals is used for irrigation of lands on both sides of Umatilla River near and below Echo, except that diverted by West Division main canal, which is 

applied to land along Columbia River in vicinity of Irrigon.

Several smaller canals also divert water between Pendleton and Umatilla, but no records 

for them were obtained.

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

March 1926 to September 1950; records for some of the canals published separately prior to 

1926.

elevations 4,265.0 feet (no storage) to 4,336.0 feet (crest of -spillway, with earth soft 

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

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

trash rack structure elevation, 4,259.75 feet. Water stored is used for irrigation near 

Madras. Gage read once daily. Daily elevations and capacity table furnished by Bureau 

of Reclamation.

Datum of Wilsonville gage is at mean sea level, datum of 1929; datum of Butteville 

gage is 50 feet above mean sea level, datum of 1929 (gage heights have been reduced 

to elevation above mean sea level). Records for entire water year 1950 obtained from 

gage at Butteville.

Drainage area. 8,400 square miles.

Records available. October 1948 to September 1950.

Extremes. Maximum discharge observed during year, 162,000 second-feet Jan. 25 (elevation 

at tiutteville, 81.03 feet); minimum daily, 4,000 second-feet Sept. 6-8 (computed from 

records for station at Salem and South Yamhill River near Whiteson).

1948-50: Maximum discharge, 196,000 second-feet Feb. 20, 1949 (elevation at Butteville, 85.20 feet; elevation at Wilsonville, 83.20 feet); minimum daily, 3,700 secondfeet Sept. 5-8, 1949 (computed from records for station at Salem).

Maximum elevation known, about 105 feet at Wilsonville, Dec. 4, 1861.

Remarks. Records good except those for periods of backwater from stop logs, gates and 

-.LOCKS at dam, and period of indefinite stage-discharge relation, which are fair. Plow 

slightly regulated by Cottage Grove, Pern Ridge, and Dorena Reservoirs. Many small 

diversions for irrigation above station.

Extremes (not including diversion to Coyote Creek) . Maximum discharge during year, 4,500 

secona-reei; jreo. i igage neigm;, 7.<m reet), rrom rating curve extended above 1,400 secondfeet on basis of shape of former curve which was well defined to 3,000 second-feet; 

minimum daily, 21 second-fest Jan. 6.

1943-50: Maximum discharge, that of Feb. 1, 1950; no flow part of June 11, 12, 1944.

Remarks.--Records of flow in river channel excellent except those for periods of no gageneignt record, which are fair; records of diversion to Coyote Creek poor. A few small 

diversions above station; several second-feet diverted around station to Coyote Creek 

channel through 24-inch concrete pipe 600 feet long, several hundred feet upstream, 

record of which is based on daily staff-gage readings and occasional measurements. Fern 

Ridge Dam, 1,000 feet above station, was completed in 1941, and has regulated flow since 

Nov. 13, 1941 (see preceding page).

lii .83 feet); minimum, 2 second-feet Sept. 1.

1940-50: Maximum discharge, 9,460 second-feet Feb. 17, 1949 (gage height, 13.89 

feet, from graph based on gage readings); minimum, that of Sept. 1, 1950.

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

tnose below 15 second-feet, which are fair. Gage read once daily until June 16 when 

water-stage recorder was installed. Diversions above station for irrigation, chiefly In 

Wapato Lake area. Diurnal fluctuation caused by dam below Gaston.

Scoggin Creek near Gaston.

b Stage-discharge relation affected t)y ice.

g Computed from graph based on observer's gage readings.
182 WILLAMETTE RIVER BASIN

Tualatin River at Farmington, Oreg.

Location. Staff gage, lat. 45°27'00". long. 122 0 57'00", in SEv sec. 29, T. 1 S., R. 2 W. , 

at highway bridge at Parmington, 1\ miles southwest of Beaverton. Auxiliary staff gage 

at highway bridge 6? miles downstream, 1 mile northeast of Scholia. Datum of each gage 

is 100.42 feet above mean sea level, datum of 1929. All discharge measurements made at 

Parmington.

Drainage area. 568 square miles.

Records available.--October 1939 to September 1950.

Average discharge. 11 years, 1,254 second-feet.

Extremes.--Maximum discharge observed during year, 13,500 second-feet Feb. 26; maximum gage 

 height, 33.5 feet Feb. 26, from graph based on gage readings; minimum discharge observed, 

23 second-feet Sept. 3.

1939-50: Maximum discharge, 17,400 second-feet Feb. 18, 1949; maximum gage height, 

34.5 feet Feb. 18, 1949, from graph based on gage readings; minimum discharge observed, 

that of Sept. 3, 1950.

Maximum stage known, about 37 feet at Farmington and 33.4 feet at gage near Scholls, 

Dec. 22 or 23, 1933.

Remarks.--Records good. Gages read twice daily. For gage heights above 8 feet, discharge 

computed using fall, as determined by twice-daily readings of auxiliary gage, as a 

factor. Slight regulation by log ponds and dam below Gaston have little effect at this 

station; considerable pondage between this station and station near Willamette. Some 

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

Discharge, in second-feet, water year October 1949 to September 1950

R. IE., 300 feet upstream from county bridge and I mile northwest of Willamette. Datum 

of gage is 85.61 feet above mean sea level, datum of 1929 (levels by Corps of Engineers).

Drainage area.--710 square miles.

Records available. July 1928 to September 1950.

Average discharge.--22 years, 1,399 second-feet (including flow of Oswego Canal).

Extremes (river only).--Maximum discharge during year, 11,100 second-feet Feb. 28 (gage 

height, la.bB feet); minimum, 12 second-feet Sept. 18.

1928-50: Maximum discharge, 23,300 second-feet Dec. 23, 1933 (gage height, 17.72 

feet, present datum); minimum observed, 2 second-feet Aug. 14-21, 1928 (gage height, 

1.27 feet, present datum).

Revisions.--The minimum discharge for the water year 1947 has been revised to 6 second-reet Sept. 17-20, superseding figure published in Water-Supply Paper 1094.

Remarks.--Records excellent above 50 second-feet and good below except those for period of 

no gage-height record, which are fair. Oswego Canal (see p. 188) diverts water 4? miles 

above station for recreational use in Oswego Lake and development of power between outlet of that lake and Willamette River, to which water is returned. Several small diversions above station for irrigation. Some regulation in low-water season by flashboards 

on crest of diversion dam of Oswego Canal. ,

Revisions (water years).--W 1014: 1943. Revised figures of discharge, in second-feet, for 

low-water period in the water year 1947, superseding those published in Water-Supply 

Papers 1094 and 1124, are given herewith:

Remarks. Records good except those for periods of doubtful gage-height record, which are 

 Fair. Gage read twice daily. Some diversions for irrigation from streams in South 

Umpqua River Basin, but low flow probably only slightly affected. Power plant at Winchester and manipulation of gates and racks of fish hatchery at Diamond Lake ordinarily 

do not affect discharge at this station.

294 ROGUE RIVER BASIN

Sucker Creek near Holland, Oreg.

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

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

gage is 1,777.84 feet above mean sea level, datum of 1929 (surveys by Bureau of Reclamation) .

Drainage area. 76 square miles.

Records available. October 1945 to September 1950 in reports of Geological Survey.

April iy4U to August 1941 at site half a mile upstream and September 1941 to September 

1945 in files of State engineer.

Extremes.--Maximum discharge during year, 2,260 second-feet Mar. '17 (gage height, 5.8 

reet, from graph based on gage readings); minimum observed, 24 second-feet Oct. 2-4, 

Sept. 23, 24.

1940-50: Maximum discharge, 5,090 second-feet Jan. 7, 1948 (gage height, 8.3 feet, 

from floodmark), by slope-area method; minimum observed, 19 second-feet Sept. 27, 28, 1947.

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

Uage read once daily, oftener during periods of high water. No regulation. Grayback 

Canal diverts water from Grayback Creek above station for domestic use and irrigation; 

most of return flow from this canal enters creek above station.

SPRINGS IN THE WALLA WALLA RIVER BASIN, OREG.-WASH. 299

Springs in the Walla Walla River Basin, Oreg.-Wash.

Ground-water overflow through many springs on the alluvial fan of the Walla Walla River 

near Milton and Preewater, Oreg., amounts to about 50,000 acre-feet 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 downstream from Preewater and extends from the vicinity 

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

Bridge, to springs in the vicinity of Dogger Creek. Within this zone are fully threefourths of the springs in the Walla Walla Basin. The intermediate and outer zones, each 

of which contains only a few springs, are about 2 miles and 4 miles, respectively, beyond 

the inner zone.

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

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

basin, discharge measurements of each of the principal springs and measurements of groundwater levels in representative wells have been made and the results published periodically 

since 1932.
