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, 1946. 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 10,900 gaging stations 

in the 48 States and also at many in the Territories of Alaska and Hawaii. In July 1946, 

5,810 gaging stations, including those in Hawaii, 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 furniehing data or by assisting In collecting data, cooperation of the first 

kind is acknowledged in connection with the description of each station affected; coope~- 

ation of the second kind is acknowledged, under the heading "cooperation," in the Introductory matter that precedes, the gaglng-statlon records In each volume. In the present 

volume, the eection on cooperation of the second kind appears on page 11.

. DEFINITION OF TERMS

The units in which etream-flow data are presented in this report and other terms usel 

herein are defined as follows:

"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 an-l 

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 the 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 usM 

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 atd 

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'deternlnes 

the stage-diecharge relation at the gage. This feature may be a natural section, a rea^h 

of the channel, or an artificial structure.

2 SURFACE WATER SUPPLY, 1946, PART 6

"Contents" Is a term applied to the volume of water In a reservoir. It Is computed on 

the basis of a level pool and does not Include bank storage unless otherwise Indicated.

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 dally flow. The records of stage are obtained either from 

direct readings on a nonrecordlng gage or from a water-stage recorder that gives a co.n~ 

tlnuous record of ttie fluctuations. Measurements of discharge are made wlfi 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 flgur? 1.

Rating tables giving the discharge for any stage are prepared from ttie d'scharge measurements. The application of the dally mean gage height to those rating tables gives the 

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

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

change in the physical features that form the control, the dally mean dlschTge Is determined by the "shifting-control method," In which correction factors basel on Individual discharge measurements and notes by engineers and observers are used In applying the 

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

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

For such times the dally mean discharge Is computed by wtat 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 ttie stream Is a factor In the determination of discharge. Information requisite for determining the elope 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 Pie rate of 

change of stage Is used as a factor In the determination of discharge.

At moet 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 ttie 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 Is 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 

by a footnote.

For most of the gaging stations on etreams In the area covered by this report the data 

presented comprise a description of the station, a table showing the dally discharge of 

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

tables are published tor all stations except those at which the dally discharge tor the 

greaterx part of the year was determined by the shirting-control method, the slope method, 

or other special methods.

The description ot the station gives the type ot gage, Its latitude and longitude as 

determined from the best available maps, and Information In regard to diversions that 

decrease the now at the gage, artificial regulation from pondage or storage, and the 

accuracy of the records. Under "Average discharge" Is given the average discharge for the 

number of years Indicated. It Is given only for stations for which there are 10 or more 

complete years of record. Under "Extremes" are given the maximum discharge and gage height; 

the minimum discharge If there Is little or no regulation; the minimum dally discharge tf 

there Is extensive regulation (also the minimum discharge If useful); and ttn 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 or a nonrecordIng gage read at the time of the crest. Likewise the minimum discharge represents the 

lowest stage, unless otherwise qualified. Selected peak discharges with the times ot 

their occurrence are given, below the table of monthly discharge, for some stations.' This 

supplementary Information Is generally omitted for a station at which the drainage area of 

the stream Is less tiian 10 or more than 10,000 square miles or at which, on most days, the 

peak discharge exceeds the mean discharge by less than 10 percent.

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 dally mean 

gage height. For stations subject to such fluctuation the dally mean gage height may not 

Indicate the true dally 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 

dally 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 dally discharge gives the discharge in 

second-feet corresponding to once-daily readings of the gage or the mean of twice-daily 

readings. For periods of rapidly changing stage the dally mean discharge Is determined 

from gage-height graphs based on gage readings made once or twice dally or oftener, as 

stated In the station description.

In the table of monthly discharge the column headed "Second-foet-days" gl'res the sum 

for each month of the figures given In the table of dally discharge. The column headed 

"Maximum" gives the maximum dally 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 dally discharge. The column headed "Mean" gives the average flow In cubic 

feet per second during the month.

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 dally contents is given. A skeleton table of capacity at gi-'en stages is 

usually given in the first report In which data for a station are published but Is omitted 

from succeeding reports.
SURFACE WATER SUPPLY, 1946, PART 6 5

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

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

and (2) the accuracy of observations of stage, measurements of flow, and Interpretatl o~\ 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 dally 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 mein 

discharge and runoff are, In general, more accurate than the dally 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 evaporation 

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 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 its Inclusion is indicated. Figures of second-feet 

per square mile and runoff in inches are also omitted If tiie drainage area Includes large 

noncontrlbutlng areas or if the average annual rainfall over the drainage area Is less 

than 20 inches.

Many gaging stations on streame 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 o* 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 daf) are 

subject to revision in succeeding water-supply papers.

Papers on surface water supply containing records from 1899 to date, grouped by y«ars 

and drainage basins, are listed by number on page 8. The data for any particular gaging 

station will, In general, be found In the reports covering the years during which tho 

station was maintained. For example, the data for 1910 to 1920 for any station In the 

area covered by part 3 are published in Water-Supply Papers 283, 303, 323, 353, 403, 433, 

453, 473, and 503, which contain records for the Ohio River Basin for those years.

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 Ind^x 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 

stannary of yearly discharge at gaging stations at which 10 or acre complete years of 

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

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 thes? 

special reports also contain other pertinent hydrologic Information and analyses and 

compilations of data relating to earlier noteworthy floods. The following list give<» the

Note.- The Soil Conservation Service of the United States Department of Agriculture has been 

collecting records of runoff, beginning In 1938, from 28 areas near Hasting, Nebr. 1 of 3,170 acres, 

1 of 2,O10 acres, 1 of 481 acres, 1 of 114 acres, and 21 of about 3 acres each. These records are 

In the files of the Soil Conservation Service.

COOPERATION

The work in the several States was done under cooperative agreements with the organizations listed below:

Colorado: Office of the State Engineer, M. C. Hinderlider; State Water Conservation Board, C. H. Stone, director.
12 SURFACE WATER SUPPLY, 1946, PART 6

Iowa: Iowa Geological Survey, A. C. Trowbridge, director and State geologist, 

and H. G. Hershey, associate State geologist; University of Iowa Institute of 

Hydraulic Research, P.M. Dawson, dean of College of Engineering, and Hunter Rouse, 

director; Iowa State Conservation Commission, F. T. Schwob, director, G. L. Ziemer, 

assistant director.

Kansas: State Board of Agriculture, Division of Water Resources, G. S. Knapp, 

chief engineer.

Minnesota: State Department of Conservation, Division of Water Resou-ces and 

Engineering, W. S. Olson, director.

Missouri: Missouri Geological Survey and Water Resources, E. L. Clark, State 

geologist; State Highway Department, C. W. Brown, chief engineer.

Montana: Office of the State Engineer, P. E. Buck; State Water Conservation 

Board; city of Bozeman.

Nebraska: Department of Roads and Irrigation, W. G. Scott, State engineer, 

through the Bureau of Irrigation, Water Power, and Drainage, R. H. Willis, chief. 

North Dakota: State Water Conservation Commission, J. J. Walsh, chief engineer. 

South Dakota: State Geological Survey, E. P. Rothrock, State geologist; State 

Department of Game, Pish, and Parks, Elmer Peterson, director.

Wyoming: Office of the State Engineer, L. C. Bishop; State Planning and Water 

Conservation Board, Gov. L: C. Hunt, president.

Financial assistance was furnished by the Corps of Engineers, United States Army, in 

the operation of 102 gaging stations, of which 3 were in Colorado, 18 in Iowa, 20 in Kansas, 

15 in Missouri, 14 in Montana, 6 in Nebraska, 7 in North Dakota, 16 in South Dakota, and 

3 in Wyoming.

Assistance was furnished also by the Weather Bureau of the United States Department of 

Commerce; the Bureau of Reclamation and the Office of Indian Affairs of the United States 

Department of the Interior; and the United States Department of State.

Assistance in collecting records was rendered by the following organizations. 

Iowa: Cities of Clarlnda, Red Oak, and Sioux City.

Missouri: Kansas City, Sho-Me Power Cooperative, Inc., and Union Electric Co. 

Montana: Montana Power Co. 

Nebraska: Loup River Public Power District.

Records for some gaging stations were obtained and published as a part of the program 

of the Department of the Interior for the development of the Missouri River Easin.

Pull cooperation exists between the Geological Survey of the United Statee Department 

of the Interior and the Dominion Water and Power Bureau, Department of Mines and Resources, 

Canada. On waters adjacent to the international boundary certain stations are maintained 

Jointly by the United States and Canada under the terms of the Boundary Water Treaty of 

1909, and others are maintained under a subsequent agreement between the two Governments. 

The records from all these stations are obtained in such a manner as to make them equally 

acceptable and available in either country. These stations are herein desigrated "international gaging stations."

DIVISION OP WORK

The stream-gaging work was conducted by the water resources branch of the Geological 

Survey, Glenn L. Parker, chief hydraulic engineer (until February 12, 1946) succeeded by 

Carl G. Paulsen, and Joseph V. B. Wells, chief of the division of surface water (after
DIVISION ,OP WORK '13

Location.- Water-stage and long-distance recorders, lat. 47°00', long. 1120 01', in S? 

sec - 5, T. 14 N., R. 3 W., a quarter of a mile downstream from Holter Dam and 3 miles 

southeast of Wolf Creek.

gage height, 6 82

Redords available.- October 1945 to September 1946.

Extremes.- Maximum discharge during year, 16,000 second-feet June 3 (g 

reet); minimum, 1,280 second-feet Aug. 31 (gage height, 0.72 foot).

Remarks.- Records good. Many diversions. Plow partly regulated by reservoirs and powsr 

plants above station. No gage-height record Oct. 1 to Dec. 6, Feb. 15 to Mar. 3, 

Apr. 18-23, Sept. 12-30. Discharge for entire year computed by Montana Power Co. f-om 

wheel ratings based on discharge measurements and by weir formula for discharge ovespillway. For periods when gage heights were available, the discharge computed by 

Geological Survey from stage-discharge relation checked The Power Co. records generally 

within 1 percent.

Monona-Harrison ditch, 1 mile west).

Records available.- May 1942 to September 1946. April 1939 to May 1942 at site 5.8 miles 

downstream, puolished as Little Sioux River near Blencoe (records equivalent).

Extremes..- Maximum discharge observed during year, 2,700 second-feet May 2S (gage height, 

Is.70 feet, from floodmark); minimum discharge observed, 26 second-feet.Sept. 4 (gage 

height, 8.66 feet). ' .

1939-46: 'Maximum discharge, 6,620 second-feet Aug. 8., 1945; maximum gage.height 

observed, 23.97 feet Aug. 7, 1945; no flow at times during period September 1939 to 

October 1940, when all of flow was carried by Monona-Harrison ditch.

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

wnicn .are poor. ' Gage read once dally. At times gart or all of flow is diverted 

above station into Monona-Harrison ditch (see p. 311), which is a dredged channel 

paralleling Little Sioux River from a point several miles above station to mouth. 1 Diversion IB regulated by changing height of an obstruction composed of earth and rock 

In equalizer ditch connecting the two channels.
