SURFACE WATER SUPPLY OF MISSOURI RIVER BASIN, 1948

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, 1948. 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 11,370 gaging stations 

1n the 48 States and also at many in the Territories of Alaska and Hawaii. In July 1948, 

5,960 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 page 12.

DEFINITION OF TERMS

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

nerein 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 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.

i "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, 1948, 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 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 shpwn 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 reacji 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 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 moat 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 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, 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 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. 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 fouho 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 sec.ond 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 are not published for canals, 

ditches, drains, or for any stream for which the pe'Sks 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 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.
6 SURFACE WATER SUPPLY, 1948, PART 6

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.

PUBLICATIONS

The results of stream-flow measurements are now published annually in 14 parts, each 

part covering an area whose boundaries coincide with natural drainage features as indicated

PUBLICATIONS

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.

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 

surface 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

Average discharge.- 67 years, 8 ,181-second-feet. 

Extremes.- Maximum discharge during year, 52,800 second-feet June 7 (gage height, 10.93

feet); minimum, 1,620 second-feet Mar. 12 (gage height, 0165 foot); minimum daily, 3,440

second-feet Jan. 1.

1881-1948: Maximum discharge observed, about 140,000 second-feet June 7, 1908 (gage

height, 18.5 feet, present datum), from rating curve extended above 50,000 second-feet;

minimum, 320 second-feet July 5, 1936 (gage height, -0.50 foot); minimum daily, 62V second-feet July 5, 1936. 

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

which are fair. Many diversions from tributaries above station. Some regulation by

reservoirs. Considerable diurnal fluctuation at medium and low flow caused by power

plants above station.

Thermopolis and Popo Agie River near Riverton).
YELLOWSTONE RIVER BASIN 187

Bighorn River at Thermopolis, Wyo.

Location.- Water-stage recorder, lat. 43°39', long. 108°12', in sec. 36, T. 43 N., R. 95 

 w., at Thermopolis, half a mile downstream from highway bridge between Thermopolis and 

hot springs. Datum of gage is 4,300.49 feet above mean sea level, datum of 1929. Discharge measurements made at former site at highway bridge.

Drainage area.- 8,080 square miles.

Records available.- May 1900 to December 1905, June 1910 to September 1948.

Average discharge.- 43 years, 1,900 second-feet.

Extremes.- Maximum discharge during year, 8,730 second-feet June 4 (gage height, 8.32 

feet); minimum daily, 498 second-feet Jan. 2.

1900-5, 1910-48: Maximum discharge, 29,800 second-feet July 24, 1923 (gage height, 

16.2 feet, site and datum then in use), from rating curve extended above 16,000 second-feet; minimum daily, 162 second-feet Nov. 14, 1940.

Remarks.- Records excellent except those for Feb. 8-16, June 11 to Sept. 30,.which are 

rair. Practically no diversions between Thermopolis and confluence of Wind and Popo 

Agie Rivers. Hot springs entering canyon below station, discharge about 25 secondfeet. Records of chemical analysis, water temperatures, and suspended sediment loads 

for the water year 1948 are given in Water-Supply Paper 1132.

* Winter discharge measurement made on this day.

f Computed on basis of partly estimated gage-height record.

Note.- Stage-discharge relation affected by ice Jan. 7-25, Jan. 29 to Feb. 17.
YELLOWSTONE RIVER BASIN 

Bighorn River near Custer, Mont.

191

'Location.- Water-stage recorder, lat. 46°07', long. 107°2ti', near center of sec. 10, T. 

4 N., K. 34 E., just downstream from Manning diversion dam, 3 miles upstream from 

Talloek Creek, 4 miles southeast of Ouster, and 4? miles upstream from mouth.

Records available.- May 1945 to September 1948.

Extremes.- Maximum discharge during year, 19,800 second-feet June 12; maximum gage height 

recorded, 9.18 feet Mar. 19 (backwater from ice); minimum discharge recorded, 1,320 

second-feet Aug. 24-29 (gage height, 1.88 feet), but may have been less during period 

of ice effect.

1945-48: Maximum discharge, 26,200 second-feet June 24, 1947 (gage height, 8.79 

feet), from rating rurve extended above 12,500 second-feet by. logarithmic plotting; 

maximum gage height recorded, 10.65 feet Mar. 20, 1947 (ice .jam); minimum daily discharge, 1,000 second-fee't Dec. 16, 17, 1945; minimum gage height, 1.52 feet Aug. 23, 

1946.

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

which are poor. Many diversions above station for irrigation. Records of suspended 

sediment loads for the water year 1948 are given in Water-Supply Paper 1132.

Diversions from Rapid Creek between Canyon Lake and Farmingdale , S. Dak.

Records of discharge are collected for twelve ditches that divert water from Rapid 

Creek, between Canyon Lake and Farmingdale, S. Dak. Each station is equipped with a waterstage recorder except as noted herein. All stations are located within 1? miles of ditch 

head gate. Water diverted by these ditches is used for irrigation of lands on both sides 

of Rapid Creek in Pennington County. Records are collected only during the irrigation 

season, Apr. 1 to Oct. 31. The flow during the other months is negligible in all ditches 

except for Leedy ditch. Leedy ditch has a winter discharge of about 5 second-feet, all 

of which returns to Rapid Creek about 1 mile downstream from point of diversion.

Records available.- October 1945 to September 1948.

Extremes.- Maximum discharge during year, 762 second-feet Mar. 26 (gage height, 8.30 feet, 

1'rom graph based on gage readings), from rating curve extended above 410 second-feet by 

logarithmic plotting; no flow on many days.

8.93 feet), from rating curve extended above 410 second-feet by logarithmic plotting; 

no flow on many days.

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

record, which are poor. Gage read once daily. Water is stored naturally offstream in 

Lake Kampeska (capacity, 35,500 acre-feet) during period"; when river is rising and then 

naturally released in part when river is falling.

Extremes.- Maximum discharge during year, 3,920 second-feet Mar. 16; maximum gage height 

observed, 25.0-feet Feb. 28, from floodmark (backwater from ice);no flow May 29 to 

June 11, June 17, July 23, Sept. 11-30; minimum gage height observed, 8.00 feet 

Oct. 28.

1939-48: Maximum discharge, 6,620 second-feet Aug. 8, 1945; maximum gage height 

observed, that of Feb. 28, 1948; no flow at times during period September 1939 to October 1940, May, June, July and September 1948, when all of flow was carried by 

Monona-Harrison ditch.

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

record, and those 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. 361), which is a dredged channel paralleling Little Sioux River from a point several 

miles above 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-feel, water year October 1947 to September 1948

LITTLE SIOUX RIVER BASIN 361

Monona-Harrison ditch near Turin, Iowa

Location.- Wire-weight gage, lat. 41°58'', long. 9S°59', on line between sees. 29 and 32, 

T, b3 N., R. 44 W., at bridge on Brown's grade, 1 mile west of gaging station on Little 

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

Sioux River and Monona-Harrison ditch, 4 miles southwest of Turin, S| 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 f I mile east).

Records available.- May 1942 to September 1948. April 1939 to May 1942 at site 4.8 

miles downstream, published as Monona-Harrison ditch near Blencoe.

Extremes.- Maximum discharge during year, 11,800 second-feet Mar, 16; maximum gage height 

observed, 22.85 feet Feb. 28 (from ice jam); minimum daily discharge, 97 second-feet 

Sept. 30 (gage height 3.41 feet).

1939-48: Maximum discharge, that of Mar. 16, 1948; maximum gage height observed, 

that of Feb. 28, 1948; 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 

Fork 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 

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

September 1948 in reports of State engineer.

Extremes.- Maximum discharge during year, 3,230 second-feet June 17; minimum daily, 256 

second-feet May 21. 

193Q-48: Maximum discharge, 12,400 second-feet June 2, 1935; minimum daily, 55 second-feet May 28, 1934, Aug. 15, 1940.

Maximum discharge recorded, 24,000 second-feet June 3, 1929 (gage height, 9.3 feet), 

but may have been exceeded by flood of June 19, 1921, which had a daily discharge of 

23,000 second-feet (maximum momentary discharge not determined), data from reports of 

State, engineer.

Remarks.- Records fair except those for periods of ice effect or doubtful gage-height 

record, which are poor. Natural flow of stream affected by transmountain diversion, 

storage reservoirs, power developments, ground-water withdrawals and diversions for 

irrigation, and return flow from irrigated areas. River flows in two channels for 

which separate records are computed; figures given herein represent combined discharge.

1930.

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

which are fair. A large part of flow is water diverted from South St. Vrain Creek for 

irrigation of lands along Lefthand Creek below station. Prior to Oct. 1, 1947, records 

were computed to include flow of a ditch which diverts water half a mile above, station; 

records for 1948 water year comparable to those for earlier periods if flow of ditch 

is added. Discharge measurements of ditch are given in following table:

* Winter discharge measurement made on this day. 

Note.- Stags-discharge relation affected by ice Nov. 23-27, Dec. 3 to Mar. 16.
PLATTE RIVER BASIN 515

Loup River near Genoa, Nebr.

Location.- Water-stage recorder, lat. 41°25'05", long. 97°43'25", in NW£ sec. 25, T. 17 

 N!, H. 4 W., 2 miles south of Genoa, 3 miles upstream from Beaver Creek, and 6 miles 

downstream from diversion dam of Loup River Public Power District.

Drainage area.- 14,440 square miles of which only about 6,000 square miles contribute 

directly to surface runoff.

Records available.- August 1928 to June 1932, October 1943 to September 1948.

Extremes.- Maximum gage height and discharge during year not determined; minimum dans' 

aischarge, 15 second-feet June 8-11.

1928-32. 1943-48: Maximum discharge, 90.,iOOO second-feet June 23, 1947 (gage height, 

10.12 feet), from rating curve extended above 32,000 second-feet by logarithmic 

plotting; minimum daily, 7 second-feet Feb. 3, 4, 1947.

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

sluggish intake action or indefinite stage-discharge relation, which are poor. Natural 

flow of stream affected by power developments, ground-water withdrawals and diversions 

for irrigation, and return flow from irrigated areas.

Records do not include flow of Loup River power canal which diverts at point 6 miles 

upstream and returns to Platte River below station; diversion began Dec. 2, 1936 (see 

p. 530).
