SURFACE WATER SUPPLY OF MISSOURI RIVER BASIN, 1949

SCOPE OP 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, 1949. 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 11,680 gaging stations 

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

30, 1949, 6,240 gaging stations, including those in Hawaii and Alaska were being maintained by the Geological Survey and cooperating organizations. Miscellaneous discharge 

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

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

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

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

volume, the section on cooperation of the second kind appears on page 12.

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 Inches.

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

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

with storage for irrigation.

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

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

represents a runoff of 0.0372 Inch from 1 square mile.

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

and discharge."

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

a reach of the channel, or an artificial structure.

2 SURFACE WATER SUPPLY, 1949, PART -6

"Contents" is a term applied to the volume of water in a reservoir. Unless otherwise 

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

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 daily flow. The records of stage are obtained either from 

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

stations at which the stage-discharge relation i,s 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 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 dally 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 nonrecordlng gage read at the 

time of the crest. Information pertaining to the accuracy of the records and conditions 

which affect the natural flow at the gaging station Is given under "Remarks."

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

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

published along with the current records In one of the annual reports. In order to make 

it easier to find such revised records, a paragraph headed "Revisions (water years)" has 

been added to the station description of all stations for which revised records have been 

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

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

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

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

1933. If there were no dally, 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 dally 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 OF FIELD DATA AND COMPUTED RESULTS 5

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

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

periods of rapidly changing stage, the daily mean discharge is determined from gage-height 

graphs based on gage readings, the frequency of which is stated In the station description.

In the table of monthly discharge the column headed "Second-foot-days" gives the sum 

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

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

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

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

feet per second during the month.

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

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

base discharge, which is given in parentheses, is selecteu 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 peaks are subject to substantial control 

by man.

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

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

but is omitted from succeeding reports.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

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

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

records.

The station description gives a statement in regard to the general accuracy of the records. "Excellent" indicates that, In general, the error In the 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 mean 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 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 noncontrlbutlng areas or If 

the average annual rainfall over the drainage area Is less than 20 inches.
6 SURFACE WATER SUPPLY, 1949, 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 sucn data are 

subject to revision in succeeding water-supply papers.

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

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

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

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

relative order as the streams and gaging stations in'ths body of the report. An Index of 

the records obtains* 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.

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. 1 of 3,470 acres, 1 of 

2,040 acres, 1 of 481 acres, 1 of 414 acres, and 24 of about 3 acres each. Thsse records 

are in the files of the Soil Conservation Service.

DIVISION OF WORK 13

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

of the Interior and the Water Resources Division, Department of Resources and Development, 

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 thesurfaee 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, P. M. Bell, 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) and for Missouri River at Omaha and at Nebraska 

City, Nebr., L. C. Crawford until Sept. 5, 1949, succeeded by V. R. Bennion on Sept. 6, 

1949; in Kansas (except for Prairie Dog Creek near Woodruff and South Fork Republican

recorder record furnished by Montana Power'Co. Oct. 1-
22 MISSOURI RIVER MAIN STEM

Missouri River at Port Benton, Mont.

Location.--Water-stage recorder, lat. 47°49', long. 110°39', in NE£ sec. 26, T. 24 B., R.

 BE., at highway bridge at Port Benton, 4 miles upstream from Shonkin Creek. Datura of 

gage is 2,614.05 feet above mean sea level, datum of 1929.

Drainage area.--24,600 square miles.

Records available.--July 1881 to September 1949 (July 1881 to September 1890, considered 

unreliable).

Average discharge.--£9 years (1890-1949), 7,690 second-feet.

Extremes.--Maximum discharge during year, 22,700 second-feet June 4; maximum gage height

 recorded, 12.98 feet Jan. 13 (backwater from ice); minimum discharge, 1,410 secondfeet Aug. 10 (gage height, 0.86 foot); minimum daily, 2,560 second-feet Aug. 21.

1881-1949: Maximum discharge, about 140,000 -second-feet June 6 (revised), 1908 

(gage height, 18.5 feet, present datum, from floodraark), from rating curve extended 

above 50,000 second-feet; minimum, 320 second-feet July 5, 1936 (gage height, -0.50 

foot); minimum daily, 627 second-feet July 5, 1936.

Note.--Figures of absolute maximum and minimum discharge and gage height for the 

water years 1891-1918 have not been determined. In general, the figures of maximum 

daily discharge for each of these years as given herein in the tables of monthly discharge represent the maximum observed discharges.

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

wnich 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.

Revisions.--Revised figures of discharge, in second-feet, for the water years 1937 and 

1938/superseding those published in Water-Supply Papers 826, 856, 876, and 917 are 

given herewith:

S~E77 5 miles south of Three Forks, 8 miles^upstream from confluence with Jefferson and 

Gallatin Rivers, and 12 miles downstream from Elk Creek.

Drainage area.--2,485 square miles.

Records available.--October 1941 to September 1949. September 1893 to May 1897 (gage 

heights only in 1893, 1894, 1897) and November 1928 to September 1932 at sites 6 m

downstream.

dies

Extremes.--Maximum discharge during year, 3,320 second-feet June 3 (gage height, 4.43 

feet); minimum daily, 910 second-feet Mar. 15.

1895-1896, 1928-32, 1941-49: Maximum dally discharge, 8.175 second-feet June 19, 

1896; maximum gage height, 10.48 feet Feb. 8, 1948 (Ice jam); minimum discharge observed, 

416 second-feet (regulated) Feb. 27, 1930.

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

which are fair. Flow regulated by Hebgen and Madison Reservoirs (see p. 67). Diversions above station for Irrigation. Ice jams during period January to March caused 

major part of flow to bypass station; discharge computed on basis of records for station 

below Madison Reservoir, near McAlllster, and includes bypass flow.

Discharge, in second-feet, water year October 1948 to September 1949

Drainage area.--8,080 square miles.

Keeoras available.--May 1900 to December 1905, June 1910 to September 1949.

Average discharge.--44 years, 1,892 second-feet.

Extremes.--Maximum discharge during year, 8,"960 second-feet June 14; maximum gage height, 

H.yy feet June 21, minimum daily, 420 second-feet Jan. 4.

1900-1905, 1910-49: 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 good, except those for periods of doubtful or no gage-height record, 

wnicn are fair. Practically no diversions between Thermopolis and confluence of Wind 

and Popo Agie Rivers. Hot springs entering canyon below station, discharge about 25 

second-feet. Records of chemical analysis, water temperatures, and suspended sediment 

loads for the water year 1949 are given in Water-Supply Paper 1162.

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 ij 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 4 secondfeet, all of which returns to Rapid Creek about 1 mile downstream from point of diversion.

The ditches divert between gaging stations on Rapid Creek as follows:

Kampeska, 2| miles northwest of Watertown, and 8% miles upstream from Willow Creek.

Records available.--October 1945 to September 1949.

Extremes.--Maximum discharge observed during year, 229 second-feet Apr. 2 (gage height, 

b.UY feet); no flow for many days.

1945-49: Maximum discharge observed, 952 second-feet Apr. 13, 1947 (gage height, 

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

no flow for many days.

Remarks.--Records fair except those for periods of ice effect 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 periods when river is rising and then 

naturally released, in part, when river is falling.

LITTLE SIOUX RIVER BASIN 423

Little Sioux River near Turin, Iowa

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

T. 83 N. ( R. 44 W., at bridge on Brown's grade, 1 mile east of gaging station on 

Monona-Harrison ditch near Turin, 2.4 miles downstream fr.om equalizer ditch connecting 

Little Sioux River and Monona-Harrison ditch, 3j miles downstream from Maple River, 

Sir miles south of Turin, 6? 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 1949. April 1939 to May 1942 at site 5.8 

miles downstream, published as Little Sioux River near Blencoe.

Average discharge.--10 years, 456 second-feet.

extremes.--Maximum discharge during year, 2,700 second-feet June 2; maximum gage height, 

26.0 feet, from floodmark, Mar. 4 (ice jam); no flow for many days.

1939-49: Maximum discharge, 6,620 second-feet Aug. 8, 1945; maximum gage heignt 

observed, that of Mar. 4, 1949; no flow at times during period September 1939 to 

October 1940, and for several months in 1948 and 1949, when all of flow was carried 

by Monona-Harrison ditch.

Remarks.--Records poor. Gage read once daily. Part or all of flow is diverted above

station into Monona-Harrison ditch (see p. 429), 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.

LITTLE SIOUX RIVER BASIN 429 

Monona-Harrison ditch near Turin, Iowa

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

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

Sioux River near Turin, \\ miles downstream from equalizer ditch connecting Little Sioux 

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 1949. April 1939 to May 1942 at site 4.8 miles 

downstream, published as Monona-Harrison ditch near Blencoe.

Average discharge.--10 years, 755 second-feet.

Extremes.--Maximum discharge during year, about 10,000 second-feet Mar. 5; maximum gage

height, 25.6 feet, from floodmarks, Mar. 4 (ice Jam); minimum daily discharge, 80 secondfeet Oct. 14.

1939-49: Maximum discharge, 11,800 second-feet Mar. 16, 1948; maximum gage height, 

that of Mar. 4, 1949; minimum discharge observed, 3 second-feet Sept. 8, 1941.

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

record, 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 \\ miles above station. The diversion is regulated by 

ehanging the height of an obstruction composed of earth and rock in the equalizer ditch.

serond-feet Aug. 16-18, 1940.

A daily discharge of 19,500 second-feet occurred July 2, 1917 (maximum momentary 

discharge not determined), from data in reports of State engineer. Flood of June 18, 

1921, may have been greater.

Remarks.--Records fair except those for periods of ice effect, 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

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.

Platte River at Brady, Nebr.

Location. Water-stage recorders (two channels), lat. 41°02 I , long. 100°23', in sees. 11

 and ^3, T. 12 N., R. 27 W., at highway bridges on county road south of Brady and 18 

miles downstream from confluence of North Platte and South Platte Rivers.

Drainage area.--56,900 square miles.

Records available.--March 1939 to September 1949 in reports of Geological Survey. April 

to September 1937, and May 1938 to September 1949 in reports of State engineer.

Extremes.--Maximum discharge during year, 14,500 second-feet June 22; minimum daily, 96

 second-feet Oct. 16.

1937, 1938-49: Maximum discharge, 15,400 second-feet May 7, 1942; no flow Aug. 22- 

24, 1941.

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

which are poor. Natural flow of stream affected by transmountain diversions, storage 

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

and return flow from irrigated areas. Tri-County main supply canal (capacity, about 

2,000 second-feet), diverts 8 miles above station; diversion started Nov. 26, 1940. 

River flows in two channels for which separate records are computed; figures given herein represent combined discharge.

Note.--No gage-height record on channel No. 1 Nov. 5-7, 14-21, 23-28, Dec. 1, 5, 7-12, 14, 15; 

discharge for that channel computed on basis of engineer's notes, weather records, and records for 

stations on South Platte River, North Platte River at North Platte, Platte River near Cozad, and 

unpublished records of diversions and inflow. Stage-discharge relation for one or both channels 

affected by ice Dec. 16 to Mar. 1.
PLATTE RIVER BASIN 455 

Platte River near Cozad, Nebr.

Location.--Water-stage recorders (two channels) lat. 40°50', long. 99°59', in sec. 18, T. 

10 N., R. 23 W., at county highway bridges l| miles south of Cozad. Prior to July 19, 

1949, south channel gage at datum 1.53 feet higher.

Drainage area. 57,200 square miles.

Records available. October 1940 to September 1949 in reports of Geological Survey. July 

to September 1932, October 1936 to September 1937 (fragmentary), May to September 1938, 

and March 1939 to September 1949 in reports of State engineer.

Extremes.--Maximum discharge during yeas, 13,600 second-fe.et June 23; minimum daily, 13 

second-feet Sept. 1, 2.

1932, 1936-37, 1938, 1939-49: Maximum discharge, 16,600 second-feet May 10, 1942; 

no flow at times during 1937-40.

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

rapidly changing discharge, which are poor. Natural flow of stream affected by transmountain diversions, 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.

Wood River near Riverdale, Nebr.

Location.--Water-stage recorder, lat. 40°47'50", long. 99°11'50", in NW^NW^ sec. 31, T. 10 

M., R. 16 W., at bridge on State highway 40, Ij miles northwest of Riverdale.

Drainage area.--379 square miles.

Records available.--June 1946 to September 1949 in reports of Geological Survey. May to 

December !9<iY at site about 21 miles downstream, published as Wood River near Kearney, 

and June 1946 to September 1949 in reports of State engineer.

Extremes.--Maximum discharge during year, 1,200 second-feet June 10 (gage height, 10.97 

reet); minimum not determined.

1946-49: Maximum discharge, 20,000 second-feet June'22, 1947 (gage height, 19.75 

feet), by contracted-opening method; no flow at times during 1946.

Remarks.--Records good above 70 second-feet and fair below, except periods of ice effect, 

no gage-height record, or indefinite stage-discharge relation, which are poor. A few 

small diversions above station for irrigation. Pump located in same pool as gage 

occasionally diverts entire flow during dry periods. Records of suspended sediment 

loads for the water year 1949 are given in Water-Supply Paper 1162.

586 PLATTE RIVER BASIN

Loup River near Genoa, Nebr.

Location.--Wire-weight gage, lat. 41°25'05", long. 97°43'25", in NWj sec. 85, T. 17 N., 

R. 4 W., 2 miles south of Genoa,3 miles upstream from Beaver Creek, and 6 miles down- , 

stream from diversion dam of Loup River Public Power District. Prior to Apr. 26, 1949, 

water-stage recorder at same site and datum.

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 1949.

Extremes.--Maximum discharge observed during year, 14,100 second-feet June 1 (gage height, 

B72B~feet); minimum daily, 8 second-feet Aug. 10.

1928-32, 1943 49: Maximum discharge, 90,000 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 or doubtful or no gageheight record, 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. 602).
