SURFACE WATER SUPPLY OF MISSOURI RIVER BASIN, 1941

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, 1941. 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 9,120 gaging stations 

in the United States and also at many gaging stations In Alaska and Hawaii. In July 1941, 

4,850 gaging stations were being maintained by the Geological Survey and cooperating organizations. Miscellaneous discharge measurements were made 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 on page 10.

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 

'vhose 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 run-off is distributed uniformly both as regards time and area.

"Run-off in Inches" is the depth to which an area would be covered If all the water 

ilraining from It In a given period were uniformly distributed on its surface. It Is used

 or comparing run-off 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

*oot 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 84 

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

-epresents a run-off of 0.0372 Inch from 1 square mile.

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

'^eights and discharge."

"Control" Is a term used to designate a feature downstream from the gage that determines 

' he stage-discharge relation at the gage. This feature may be a natural section, a reach

 \f the channel, or an artificial structure.

EXPLANATION OF DATA

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

i'*scharge, and general Information used to supplement the records of stage and discharge

1
2 EXPLANATION OF DATA

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 on plate 1.

Rating tables giving the discharge for any stage are prepared from the discharge measurements. The application or the dally mean gage height to these 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 discharge le 

determined by the "shifting-control method," In which correction factors based on Individual discharge measurements are used In applying the gage heights to the rating tables.

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. The days 

included in the periods of Ice effect and the days during the winter period on which discharge measuremente were made are indicated in the table by symbols referring to footnotes.

For nost 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 run-off. Skeleton rating 

tables are published for all stations except those at which the dally 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 

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). Unlees otherwise qualified, the 

maximum discharge corresponds to the crest stage, obtained by use of a water-stage

recorder or a nonrecordlng 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 stations having drainage areas of less than 10 square miles or more than 10,000 square miles or If the peak 

discharges usually exceed the corresponding mean discharges for the day by less than 10 

percent.

For stations equipped with nonrecordlng 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 flashy floods the da-lly mean discharge Is determined from 

gage-height graphs baeed on gage readings made once or twice dally or oftener, as stated 

In the station description. 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 etatlons subject to such fluctuation the 

dally mean gage height may not Indicate the true daily mean discharge, which must be obtained by averaging the discharge for parte of the day or by using the dlecharge Inte-' 

grator, 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 etatlon.

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 dally discharge. The column headed 

"Maximum" gives the maximum dally discharge and not the momentary discharge when the 

water surface was at crest stage. Likewise, In the column headed "Minimum" the quantity 

given le 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 a few of the 

more Important lakes and reservoirs a table showing dally 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.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of stream-flow data depends primarily on (1) the permanency of the stagedischarge relation 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 daily records are accurate within 

5 percent; "good," within 10 percent; "fair," within 15 percent; and "poor," within 20 or 

a higher percent.

Yield at some stations as indicated by monthly means may vaiy 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 "secondfeet per square mile" and "run-off in inches" are not published unless storage or diversion 

records are Included indicating the extent of the regulation or diversion or unless
4 ACCURACY OF FIELD DATA AND COMPUTED RESULTS

satisfactory adjustments can be made for changes In contents of reservoirs or for other 

changes Incident to use and control. Figures of second-feet per square mile and run-off 

In Inches are also omitted If the 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 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 mast first be satisfied.

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

the station. The table of dally 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.

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, 503, which contain records for the Ohio River Basin Tor 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. 6), contains a summary of yearly discharge at gaging 

stations In the area covered by that report. Gaging stations at which 10 or more complete years of record have been collected are represented. These summaries are available 

also as separate reprints.

From tine to time 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 In alphabetical order by States and drainage 

basins.

22 MISSOURI RIVER MAIN STEM

Missouri River at power-plant ferry, near Zortman, Mont.

Location.- Water-stage recorder, lat. 47°44', long. 108°56', In HWi sec. 29, T. 23 N., R. 

32 E., at power-plant ferry, 5 miles downstream from Cow Creek and 30 miles southwest 

of Zortman.

Drainage area.- 40,600 square miles.

Records available.- February 1934 to September 1941.

Extremes.- Maximum discharge during year, 14,000 second-feet June 15 (gage height, 6.64 

feet); maximum gage height. 8.00 feet Mar. 26, Ice Jam; minimum, 1,880 second-feet Nov. 

11 (gage height, 2.45 feet).

1934-41: Maximum discharge, 37,500 second-feet June 25, 1938 (gage height, 10.25 

feet), from rating curve extended above 24,000 second-feet; maximum gage-height 

recorded, 14.49 feet Mar. 16, 1935, while Ice was breaking; minimum discharge, 1,120 

second-feet (regulated) July 8, 1936 (gage height, 1.92 feet); minimum dally, 1,220 

second-feet Dec. 13, 1936.

Remarks.- Records good except those ror periods of wire-weight gage readings, which are 

fair, and those for period of Ice effect, which are poor. Many diversions from tributaries. Flow partly regulated by reservoirs. Considerable fluctuation at medium and 

low stages caused by power plants above station.

LITTLE SIOUX RIVER BASIN 223

Little Sioux River near Blencoe, Iowa

Location.- Wire-weight gage, lat. 41°54', long. 95°58', near center of sec. 21, T. 82 N.,

 R. 44 W., at bridge on county road K, 1 mile east of gaging station on Monona-Harrlson 

ditch 6 miles southeast of Blencoe, 8 miles downstream from equalizer ditch connecting Little Sioux River and Monona-Harrison ditch, 9 miles downstream from Maple River, 

101 miles upstream from mouth of Monona-Harrlson ditch, and 11 miles upstream from 

mouth. Datum of gage Is 1,010.26 feet above mean sea level, datum of 1929 (levels by 

Corps of Engineers, U. S. Army).

Drainage area.- 4,470 square miles (combined area above this station and above station on 

Monona-Harrlson ditch, 1 mile west).

Records available.- April 1939 to September 1941.

Extremes.- 1939: Maximum discharge observed during period April to September, 1,720

 second-feet Aug. 2 (gage height, 22.00 feet); no flow Sept. 1-30.

1939-40: Maximum discharge observed during water year, 2,820 second-feet June 4 

(gage height, 2§.26 feet, from floodmark), by slope-area method; no flow at times during

1940-41: Maximum discharge during water year, 3,250 second-feet Sept. 16 (gage 

height, 24.60 feet, from graph based on gage readings); no flow Oct. 1-12.

Remarks.- Records fair except those prior to Sept. 12, 1940, and those for periods of ice

 effect during 1940-41, all of which are poor. Oage read once dally, more often during 

high stages. At times part or all of flow Is diverted above station into MononaHarrison ditch (see p. 233 ), which Is a dredged channel paralleling Little Sioux River 

from a point several miles above station to mouth of river. Diversion is changed by 

regulating height of an obstruction composed of earth and rock in equalizer ditch connecting river and ditch.

Discharge, in second-feet,

LITTLE SIOUX RIVER BASIN 227

West Fork ditch at Holly Springs, Iowa

Location.- Wire-weight gage, lat. 42°16', long. 96°05', between sees. 9 and 16, T. 86 N., 

R. 45 W., at bridge on State Highway 141 at west edge of village of Holly Springs, 12 

miles upstream from Wolf Creek, 16i miles north of Onawa, and 22 miles southeast of 

Sioux City'. Datum of gage Is 1,052.82 feet above mean sea level, datum of 1929 (Corps 

of Engineers, U. S. Army, bench mark).

Drainage area.- 395 square miles.

Records available.- April 1939 to September 1941.

Extremes.- 1939: Maximum discharge observed during period April to September, 990 secondfeet Aug. 2 (gage height, 13.95 feet); minimum observed, 3 second-feet Sept. 15-26.

1939-40: Maximum discharge during water year, 3,360 second-feet June 4 (gage height, 

19.85 feet, from floodmark), by slope-area method; minimum, 2 second-feet for many days 

during January and February.

1940-41: Maximum discharge observed during water year, 1,940 second-feet Sept. 15 

(gage height, 18.95 feet); minimum observed, 1 second-foot Sept. 6.

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

which are poor. Gage read twice dally. West Fork ditch is a dredged channel which 

diverts flow of West Fork of Little Sioux River at Holly Springs and carries it 5i 

miles south, thence southwest 6i miles to a point li miles west of Kennebec, where 

Wolf Creek enters from the left. From this point the ditch roughly parallels Little 

Sioux River to a point about 3 miles southwest of Turin where an equalizer ditch connects It with Little Sioux River. From this point south ditch is known as MononaHarrison ditch.

Monona-Harrlson ditch near Blencoe, Iowa

Location.- Wire-weight gage, lat. 41°54', long. 95°59', near center of sec. 20, T. 82 N., 

R. 44 W., at bridge on county road K, 1 mile west of gaging station on Little Sioux 

River near Blencoe, Iowa, 5 miles southeast of Blencoe, 6 miles downstream from equalizer ditch connecting Little Sioux River and Monqna-Harrlson ditch, and 8i miles upstream from mouth. Datum of gage Is 1,009.60 feet above mean sea level, datum of 1929, 

(levels by Corps of Engineers, u. S. Army).

Drainage area.- 4,470 square miles (combined area above this station and above station on 

Little sioux River near Blencoe, Iowa).

Records available.- April 1939 to September 1941.

Extremes.- 19351Maximum discharge observed during period April to September, 3,140 

second-feet July 7 (gage height, 20.85 feet); minimum observed, 44 second-feet Sept. 

28.

1939-40: Maximum discharge during water year, 4,820 second-feet June 4 (gage height, 

24.60 feet, from floodmark), by slope-area method; minimum observed, 12 second-feet 

July 8.

1940-41: Maximum discharge during water year, 3,230 second-feet Sept. 16 (gage 

height, 22.27 feet, from gage reading at crest of rise); minimum observed, 3 secondfeet Sept. 8.

Remarks.- Records fair except those for periods of ice effect, backwater from bridge construction or Missouri River, or doubtful gage-height record, all of which are poor. 

Gage read once daily, more often during high stages. Monona-Harrlson ditch is a 

dredged channel and Is a continuation of the West Fork ditch, paralleling the Little 

Sioux River, Into which It empties a quarter of a mile above Missouri River. At times 

part or all of flow In the Little Sioux River is diverted Into Monona-Harrison ditch 

through an equalizer ditch which connects the two channels 6 miles above station. Likewise, the flow of Monona-Harr1son ditch can be diverted Into the Little Sioux River. 

The diversion Is regulated by changing the nelght of an obstruction composed of earth 

and rock in equalizer ditch.
