SURFACE WATER SUPPLY OF MISSOURI RIVER BASIN, 1947

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, 1947. 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 11,100 gaging stations 

in the 48 States and also at many in the Territories of Alaska and Hawaii. In July 1947, 

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

kind is acknowledged 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 page1 11.

DEFINITION OF TERMS

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

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 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 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 used 

for comparing runoff with rainfall, which is usually expressed in inphes.

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-day11 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, or an artificial structure.

2 SURFACE WATER SUPPLY, 1947, 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 OP 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 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 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 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 ana 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 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 streams In the area covered by this report the data 

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

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, its latitude and longitude as 

determined from the best available maps, and information in regard to diversions that 

decrease the flow 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 daily discharge if there is extensive regulation (also the 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 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 of 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 than 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 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 dally discharge gives the discharge 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 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 daily 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 daily contents 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.
SURFACE WATER SUPPLY, 1947, PART e 5

ACCURACY OP 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 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 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.

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 anpropriations 

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.

Papers on surface water supply containing records from 1899 to date, grouped by years 

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 the 

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 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.

RECORDS OF DISCHARGE COLLECTED BY AGENCIES OTHER THAN THE GEOLOGICAL SURVEY II

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 OF DISCHARGE COLLECTED BY AGENCIES OTHER THAN THE GEOLOGICAL SURVEY

The Soil Conservation Service of the United States Department of Agriculture has 

collected records of runoff from 28 areas near Hastings, Nebr. l of 3,470-acres, 1 of 

2,040 acres, 1 of 481 acres, 1 of 414 acres, and 24 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.

Iowa: Iowa Geological Survey, A. C. Tro»bridge, director and State geologist, 

succeeded by H. G. Hershey; University of Iowa Institute of Hydraulic Research, 

F. M. Dawson, dean of College of Engineering, and Hunter Rouse, director; Iowa 

State Conservation Commission, G. L. Ziemer, director, and B. F. Stiles', assistant 

director.

Engineering, W. S. 01son, director, succeeded by C. T. Ekman.

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 Engineer1 , F. 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, Fish, 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 in the operation of 108 

gaging stations, of which 3 were in Colorado, 18 in Iowa, 19 in Kansas, 15 in Missouri, 

16 in Montana, 8 in Nebraska, 8 in North Dakota, 17 in South Dakota, and 4 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 Clarinda, Red Oak, and Siuux City.

Missoari: 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 Basin.

Full cooperation exists between the Geological Survey of the United States 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 designated "international gaging stations."

DIVISION OF WORK

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

Survey, Carl G. Paulsen, chief hydraulic engineer, and Joseph V. B. Wells, chief of the 

surfacb water branch. The data for the stations in the several States were collected and 

prepared for publication under the supervision of the district engineers as follows: In 

Colorado, Robert Follansbee, the work being done in collaboration with M. C. Hinderlider, 

State engineer, and L. T. Burgess, State chief hydrographer; in Iowa (except for Missouri 

River at Sioux City and Big Sioux River at Akron), L. C. Crawford; in Kansas (except for

a Ho gage-height record; discharge computed on basia of records for nearby 

b Stage-discharge relation affected by Ice.
MISSOURI RIVER MAIN STEM

Missouri River below Holter Dam, near Wolf Creek, Mont.

Location.- Water-stage and long distance recorders, lat. 46°59'40", long. 112 0 00'50", in 

S'l sec. 5, T. 14 N., R. 3 W., a quarter of a mile downstream from Holter Dam and 

3 miles southeast of Wolf Creek.

Records available.- October 1945 to September 1947.

Extremes (regulated).- Maximum discharge during year, 27,200 second-feet June 12 (gage 

height, 9.75 feet); minimum, 760 second-feet Aug. 15 (gage height, 0.20 foot); minimum 

daily, 2,560 second-feet Aug. 8.

1946-47: Maximum discharge, that of June 12, 1947; minimum, that of Aug. 15, 1947; 

minimum daily, 1,560 second-feet Aug. 31, 1946.

Remarks.- Records excellent. Many diversions. Plow regulated by reservoirs and power 

plants above station.

No gage-height record Oct. 1 to Feb. 10, Mar. 4 to 8; discharge computed by Montana 

Power Co. from wheel ratings based on discharge measurements and by weir formula for 

discharge over spillway (for periods when gage heights were available, the discharge 

computed by Geological Survey from stage-discharge relation checked that of Montana 

Power Co. well within 1 percent).

Records available.- November 1930 to September 1947.

Average discharge.- 16 years (1931-47), 24,300 second-feet.

Extremes.- Maximum discharge during year, 176,000 second-feet Apr. 3 (gage height, 11.00 

reet); minimum daily, 4,100 second-feet Dec. 25 to Jan. 1; minimum gage height observed, 

0.06 foot Dec. 3.

1930-47: Maximum discharge, 282,000 second-feet Apr. 8, 1943; maximum gage height, 

14.80 feet Mar. 22, 1932 (ice jam); minimum daily discharge, 2,700 second-feet Nov. 15, 

16, 1940; minimum gage height, -0.67 foo-t Dec. 29, 1939.

Maximum stage known, 30.5 feet, present datum, Apr. 5, 1881 (ice jam).

Remarks.- Records excellent except those computed on basis of wire-weight gage readings, 

which are good, and those for periods of ice effect or no gage-height record, which are 

fair. Flow partly regulated by Fort Peck Reservoir.

ADsaroicee; records not equivalent during irrigation season.

Average discharge.- 12 years, 412 second-feet.

Extremes.- Maximum discharge during year, 2,080 second-feet June 21; maximum gage height, 

3.33 feet July 8; minimum daily discharge, 110 second-feet Feb. 27 to Mar. 3.

1935-47: Maximum discharge observed, 4,850 second-feet June 22, 1937 (gage height, 

6.36 feet), from rating curve extended above 2,000 second-feet; minimum observed, 31 

second-feet May 25, Dec. 29, 1936; minimum gage height observed, 0.99 foot Jan. 25,

350 LITTLE SIOUX RIVER BASIN

Little Sioux River near Turin, Iowa

Location.- Wire-weight gage, lat. 41°58', long. 95°58', on line between sees. 28 and 33,

 Tr~S3~N., R. 44 W., at bridge on Brown's grade, 1 mile east of gaging station on MononaHarrison ditch near Turin, 2.4 miles downstream from equalizer ditch connecting little 

Sioux River and Monona-Harrison ditch, 3i mi]es downstream from Maple River, 3¥ miles 

south of Turin, &^ miles northeast of Blencoe, and 16? miles upstream from mouth. Datum 

of gage is 1,020.00 feet above mean sea level, datum of 1929 (Corps of Engineers bench 

mark).

Drainage area.- 4,460 square miles (combined area above this station and above station on 

Monona-Harrison ditch, 1 mile west).

Records available.- May 1942 to September 1947. April 1939 to May 1942 at site 5.8 miles

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

Extremes.- Maximum discharge during year, 3,640 second-feet June 22 (gage height. 20.7

reet, from floodmark); minimum daily discharge, 0.1 second-foot Sept. 1, 2, 25-28; minimum gage height observed. 8.00 feet Sept. 1, 2.

1939-47: Maximum discharge, 6,620 second-feet Aug. 8, 1945; maximum ga^e 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

 anrt tnose below 10 second-feet, which are poor. Gage read once daily. At times part 

or all of flow is diverted above station into Monona-Harrison ditch (see p. ), which 

is a dredged channel paralleling Little Sioux River from a point several miles abuve 

station to mouth. Diversion is regulated by changing height of an obstruction composed 

of earth and rock in equalizer ditch connecting the two channels.

Discharge, in second-feet, water year October 1946 to September 1947

LITTLE SIOUX RIVER BASIN 355 

Monona-Harrison ditch near Turin, Iowa

Location.- Wire-weight gage, lat. 41°58', long. 95°59', on line between sees. 29 and 32, 

mno., R. 44 W., at bridge on Brown's grade, 1 mile west of gaging station on Little 

Sioux River near Turin, 1-| miles downstream from equalizer ditch connecting Little 

Eioox River and Monona-Harrison ditch, 4 miles southwest of Turin, 5? miles northeast 

of Blencoe, and 13 miles upstream from mouth. Datum of gage Is 1,020.00 feet above 

mean sea level, datum of 1929 (Corps of Engineers bench mark).

Drainage area.- 4,460 square miles (combined area above this station and above station on 

Little Sioux River, 1 mile east).

Records available.- May 1942 to September 1947. April 1939 to May 1942 at site 4.8 miles 

downstream, published as Monona-Harrison ditch near Blencoe (records equivalent).

Extremes^- Maximum discharge during year, 10,000 second-feet June 22 (gage height, 19.3 

feet "from floodmark); minimum dally, 163 second-feet Sept. 29 (gage height, 3.60 

feet).

1939-47: Maximum discharge, that of June 22, 1947; maximum gage height observed, 

21.08 feet June 16, 1944; minimum discharge observed, 3 second-feet Sept. 8, 1941.

Remarks.- Records fair except those for periods of ice effect, which are poor. Gage read 

once daily. Monona-Harrison ditch is a dredged channel and is a continuation of West 

Pork ditch, paralleling Little Sioux River into which It empties a quarter of a mile 

above Missouri River. At times part or all of flow of Little Sioux River is diverted 

into Monona-Harrison ditch through an equalizer ditch which connects the two channels 

li miles above station. The diversion is regulated by changing the height of an obstruction composed of earth and rock in the equalizer ditch.

Discharge, in second-feet, water year October 1945 to September 1947

N., H. 10 E., just downstream from Rawhide Creek and 3^ miles north of Waterloo.

Drainage area.- 6,900 square miles (includes about 400 square miles of closed basin in 

sand hills area of Nebraska for which drainage is indeterminate).

Records available.- July 1940 to September 1947. May 1911 to July 1913 (fragmentary), 

August, 192H to July 1940 at site at Waterloo, 4| miles downstream. April 1899 to 

November 1903 and July 1913 to September 1915 (fragmentary) at site 10 miles upstream, 

published as Elkhorn River at Arlington.

Average discharge.- 21 years (1911-13, 1928-47), 865 second-feet.

Extremes.- Maximum discharge during year, 14,100 second-feet June 13 (gage height, 7.16 

Feet); minimum daily, 230 second-feet Dec. 29.

1911-13, 1928-47: Maximum discharge, 100,000 second-feet June 12, 1944 (gage height, 

16.6 'feet, from floodmark in gage well), from current-meter measurement of main channel 

and velocity-area studies of overflow section; minimum observed, 50 second-feet Nov. 12, 

1940.

Maximum flood known, that of June 12, 1944.

Remarks.- Records good except those for periods of ice effect or doubtful or no gageheight record, which are fair. Several small diversions above station for irrigation.

Correction.- A discharge measurement of Elkhorn River at Waterloo, Nebr., was published 

erroneously in 18th Annual Report, Part IV (p. 193), under date of July 23, 1896, and 

discharge, 4.95 second-feet, and in Water-Supply Paper 230 (p. 158) under same date and 

discharge, 5 second-feet. The correct date is July 17, 1896, and discharge, 495 secondfeet .
