SCOPE OF WORK

This volume is one of a series of 18 reports presenting measurements of stage, discharge , and content of streams, lakes, and reservoirs in the United States during the 

water year ending September 30, 1951. Since 1888, when the United States Geological Survey first studied streamflow in relation to problems of irrigation, similar measurements 

have been made at more than 12,400 gaging stations in the 48 States and at many others in 

the Territories of Alaska and Hawaii. On September 30, 1951, the Geological Survey and 

cooperating organizations were maintaining 6,730 gaging stations, including those in 

Alaska and Hawaii. Miscellaneous discharge measurements were made at many other points 

in the 1951 water year.

DEFINITION OF TERMS AND ABBREVIATIONS

The terms of streamflow and other hydrologic data, as used in this report, are defined 

as follows:

Cubic foot per second (cfs) 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.

Cubic feet per second per square mile (cfsm) is the average number of cubic feet of 

water flowing per second from each square mile of area drained, assuming that the runoff 

is distributed uniformly in 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. The term 

is used for comparing runoff with rainfall, which is also usually expressed in inches.

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 relation to storage 

for irrigation.

Cfs-day is the volume of water represented by a flow of 1 cubic foot per second 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 the relation between gage height and the amount of water 

flowing in a channel, expressed as volume per unit of time.

Control designates a feature downstream from the gage that determines the stage-discharge relation at the gage. This feature may be a natural constriction of the channel, 

a long reach of the channel, or an artifical structure.
EXPLANATION OF DATA 3

Contents is the volume of water in a reservoir. Unless otherwise indicated, volume is 

computed on the basis of a level pool and does not Include bank storage.

The drainage area of a stream at a specified location is that area, measured in a horizontal plane, which is so enclosed by a topographic divide that direct surface runoff from 

precipitation normally would drain by gravity into the river above the specified point. 

Figures of drainage area given herein include all closed basins, or noncontributlng areas, 

within the area unless otherwise noted.

NEW DOWNSTREAM ORDER OF LISTING GAGING STATIONS

Beginning with the series of reports for the water year ending September 30, 1951, the 

order of listing gaging-station records has been changed. In this report, in a downstream 

direction along the main stem all stations on a tributary entering above a main-stem station 

are listed before that station. If a tributary enters between two main-stem stations, it is.s 

listed between them. A similar order is followed in listing stations on first rank, second 

rank, and other ranks of tributaries. To indicate the rank of any tributary on which a 

gaging station is situated and the stream to which it is immediately tributary, each indention in the listing of gaging stations in the table of contents of this report represents 

one rank. This new downstream order and system of indention show which gaging stations are 

on tributaries between any two stations on a main stem and the rank of the tributary on 

which each gaging station is situated.

The order of listing used before the publication of the 1951 report listed first all 

stations on the main stem from headwaters toward mouth, then all stations on the uppermost 

tributary to the main stem from the tributary's source to mouth, and then all stations from 

source to mouth of the uppermost tributary to the tributary.

EXPLANATION OF DATA

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

of discharge. In addition, observations of factors affecting the stage-discharge relation, 

weather records, and other information are used to supplement base data 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 fluctuations. 

Measurements of discharge are made with a current meter by the general methods adopted 

by the Geological Survey on the basis of experience in stream gaging since 1888. These 

methods are described in Water-Supply Paper 888 and are also outlined in standard textbooks on the measurement of stream discharge. Typical structures in use at gaging stations 

are shown in figure 1.

Rating tables giving the discharge for any stage are prepared from stage-discharge 

relation curves defined by discharge measurements. If extensions to the rating curves 

are necessary to define the extremes of discharge, they are made on the basis of Indirect 

measurements of peak discharge (such as slope-area or contracted-opening measurements, 

computation of flow over dams or weirs, and by other methods), velocity-area studies, and 

logarithmic plotting. 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 dally 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

EXPLANATION OP DATA 5

the gage heights to the rating tables. If the stage-discharge relation for a station is 

temporarily changed by the presence of aquatic growth or debris on the control, the daily 

mean discharge is computed by what is essentially the shifting-control method.

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

reservoirs, tributary streams, or other sources. This necessitates the use of the slope 

method in which the slope or fall in a reach of the stream is a factor in determining 

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 stagedischarge relation is affected by changing stage. If so, 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, and it becomes 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 other stations in the same or nearby basins. If the 

stage-discharge relation is affected by ice, this information is given in a note to the 

table. No mention is made of occasional days of ice effect if the degree of accuracy of 

daily records is not changed.

The data herein presented generally comprise a description of the station, a skeleton 

rating table, and a table showing the daily discharge and monthly and yearly discharge and 

runoff of the stream.

The description of the station gives the location, drainage area, records available, 

type and history of gages, average discharge, extremes of discharge, general remarks, and 

notations of revisions of the previously published record. The location of the gaging 

station and the drainage area are obtained from the most accurate maps available. River 

mileage, given under "Location" for some stations, is that determined and used by the Corps 

of Engineers unless otherwise noted. Under "Gage" are given the type of gage currently in 

use and the datum of the present gage above mean sea level, and a, condensed history of the 

types of gages, locations, and datums of previous gages for which discharge records are 

generally equivalent to those at the present site. Under "Average discharge" is given the 

average discharge for the number of years indicated. It is not given for stations having 

fewer than five 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, a crest-stage indicator, or a nonrecording gage read at the time of the crest. If the maximum gage height did not occur 

at the same time as the maximum discharge, it is given separately. Information pertaining 

to the accuracy of the records and conditions which affect the natural flow at the gaging 

station is given under "Remarks."
6 SURFACE WATER SUPPLY, 1951, PART 6A

Previously published records of some stations have been found to be in error on the 

basis of data or information later obtained. 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 description of all stations for which revised records have been published. 

Listed therein are all the reports in which revisions have been published, 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 water years only one number is 

given; for instance, 1933 stands for the water year October 1, 1932, to September 30, 

1933. If no daily, monthly, or annual figures of discharge are concerned 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 cubic feet per second 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 cubic feet 

per second 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.

Skeleton rating tables are published for all stations except those at which the daily 

discharge for the greater part of the open-water period was determined by the shiftingcontrol method, the slope method, or other special methods involving an equivalent adjustment to the gage height of more than one-tenth foot.

For stations equipped with water-stage recorders, except those on streams subject to 

sudden or rapid fluctuation, the daily 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 corresponding townee-daily readings of the gage, or to the mean of twice-daily 

readings, or to 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 daily discharge, the values for the maximum day and the minimum day for 

each month are underlined. If the value is repeated, it is underlined only on the first 

day of its occurrence.

In the monthly summary below the daily table, the line headed "Total" gives the sum of 

the daily values; it is the total cfs-days for the month. The line headed "Mean" gives 

the average flow in cubic feet per second during the month. Runoff for the month may be 

expressed in cubic feet per second per square mile (line headed "Cfsm"), or in inches (line 

headed "in."), or In acre-feet (line headed "Ac-ft"). Values for cubic feet per second per
ACCURACY OF FIELD DATA AND COMPUTED RESULTS 7

square mile and runoff, in inches, are omitted if the drainage area includes large noncontributing areas, or if the average annual rainfall over the drainage basin is usually less 

than 20 inches.

In the yearly summary below the monthly summary, the values of maximum are the maximum 

daily discharges, not the momentary discharges when the water was at crest stage. Likewise, the minimums in this summary are the minimum daily discharges.

Peak discharges and the times of their occurrence and corresponding gage heights of 

most stations are listed below the table of daily and monthly discharge. 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 peaks are subject to substantial control by man.

Footnotes to the table of daily discharge indicate periods when discharge was computed 

or estimated by unusual or special methods during periods of no gage-height record and ice 

effect, or by other effects that reduce the degree of accuracy of the records. Days on 

which discharge measurements were made are indicated by asterisk and footnote unless they 

were made at frequent regular intervals, in which instance the general frequency of discharge measurements is given under "Remarks" in the station description.

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 the reservoir are published, 

but it is omitted from succeeding reports.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of streamflow data depends primarily on (1) the stability 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 discharge, and interpretation 

of records.

The station description states the degree of 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 nearly accurate than the daily records.

Runoff at some stations, as indicated by the monthly mean, may vary widely from natural 

runoff, owing to diversion, consumption, regulation by storage, increase or decrease in 

evaporation due to artificial causes, or to other factors. For such stations, values of 

cubic feet per second per square mile and runoff, in inches, are not published unless 

storage or diversion records are included to indicate the extent of the regulation or diversion, or unless satisfactory adjustments can be made for changes in contents of reservoirs or for other changes incident to use and control. Evaporation from a reservoir is 

not included in the adjustments for changes in reservoir contents, unless it is so stated. 

Even at those stations where adjustments are made, large errors in computed runoff may 

occur when relatively large negative adjustments are made or when evaporation is large in 

comparison with the observed discharge.
SURFACE WATER SUPPLY, 1951, PART 6A

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 actually show the water supply available at the stations for further development, 

because water must first be supplied to existing irrigation systems.

PUBLICATIONS

To facilitate publication of the annual series of reports, the area of the United 

States is divided into 14 parts whose boundaries coincide with certain natural drainage 

lines. Formerly, the results of streamflow measurements were published in 14 volumes, one 

for each of the 14 parts. Beginning with the reports for 1951, the records are published 

in 18 volumes, there being 2 volumes each for Parts 1, 2, 3, and 6. The boundaries of the 

various parts are indicated by the following list and the map in figure 2.

The records at most of the stations discussed in these reports extend over many 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 are listed in the same order as 

the streams and gaging stations in the body of the report. An index of the records obtained before 1904 has been published in Water-Supply Paper 119.

Each of the reports on the surface-water supply for the year 1939 (Water-Supply Paper 

876 for the Missouri River basin above Sioux City, Iowa) contains, for the area included 

in that report, a summary of yearly discharge at gaging stations at which 10 or more complete years of record had been collected. These summaries were reprinted separately.

Reports also 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 may have been revised), as well as some records not contained in 

the annual series of water-supply papers. The following table lists reports of this type 

for Missouri River basin above Sioux City, Iowa.

Note. In addition to the records contained in the reports listed above, the following States 

have Issued annual or biennial reports In which are contained records of discharge: Montana, 

Nebraska, North Dakota, South Dakota, and Wyoming.

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 special 

reports also contain other pertinent hydrologic information and analyses and compilations 

of data relating to earlier notable floods. The following list gives the numbers and

RECORDS OF DISCHARGE COLLECTED BY AGENCIES OTHER THAN THE GEOLOGICAL SURVEY

During the water year 1951, no continuous records of discharge collected by agencies 

other than the Geological Survey were reported for the area covered by this report.

HYDROLOGIC CONDITIONS

The water year 1951 was characterized by above-normal runoff over most of the Missouri 

River basin above Sioux City, Iowa. Although local floods occurred in widely scattered 

sections at various times during the year, no major floods were reported except in the 

Big Sioux River basin, in the extreme northwestern corner of Iowa, where the greatest 

flood of recent years occurred during early April.

For three key stations in the area covered by this report, a comparison of monthly and 

annual mean discharges during the 1951 water year with the median for the 25-year period 

1921-45 is shown in figure 3 on the following page.

Gage.--Water-stage recorder. Datum of gage is 2,543.40 ft above mean sea level (levels 

t>y Corps of Engineers).

Average discharge. 16 years, 7,688 cfs.

Extremes.--Maximum discharge during year, 32,800 cfs May 14 (gage height, 9.59 ft); maximum gage height, 16.92 ft sometime between Mar. 27 and Apr. 10, from high-water mark 

in well (backwater from ice); minimum discharge, 1,820 cfs Dec. 6 (gage height, 2.81 

ft), but may have been less during period of no gage-height record; irinimum daily, 

3,250 cfs Jan. 28.

1935-51: Maximum discharge, 92,000 cfs June 20, 1948 (gage height, 17.63 ft), from 

rating curve extended above 60,000 cfs by logarithmic plotting; miniirum, 480 cfs July 

5, 6, 1936 (gage height, 1.70 ft); minimum daily, 638 cfs July 5, 1936.

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

which are fair. Diversions for irrigation of about 830,000 acres above station. Flow 

regulated by 14 reservoirs (see p.290). Considerable diurnal fluctuation at medium and 

low flow caused by seven powerplants above station.

Nov. 2, 1921, water-stage recorder at site 1,000 ft upstream at datum 1.61 ft higher. 

Nov. 3, 1921, to Aug. 28, 1947, water-stage recorder at site 60 ft upstream at present 

datum.

Average discharge. 35 years (1917-51), 290 cfs.

Extremes. Maximum discharge during year, 5,860 cfs June 25 (gage height, 8.80 ft, from 

partly estimated gage-height record); minimum daily, 6 cfs Feb. 12, 13.

1909-51: Maximum discharge, 7,460 cfs May 22, 1927 (gage height, 11.41 ft), by 

slope-area determination; no flow at times.

Remarks. Records excellent except those for periods of ice effect or discharge above 4,000 

cfs, which are fair. Since 1917 flow increased during irrigation season by water from 

St. Mary Canal. Several small diversions for irrigation above station.

Cooperation.--This is one of the international gaging stations maintained Jointly by the 

United States and Canada under the Boundary Waters Treaty. Records collected and compiled Jointly with the Water Resources Division, Department of Resources and Development, Canada.

Location (revised).--Lat 48°59<20", long. 106°47<30", In SE£ sec. 1, T. 37 N., R. 37 E., 

on right bank three-quarters of a mile south of international boundary, 2 miles upstream from Horse Creek, and 9 miles northeast of Thoeny, Mont.

Drainage area.--242 sq mi.

Records available.--March 1927 to September 1951 in reports of Geologicel Survey. May 

1914 to October 1915, March 1927 to September 1951 in reports of Department of 

Resources and Development, Canada. No winter records most years. Published as "near 

Barnard, Mont." 1914-15 (other records published as "near Barnard, Mont." for the 

period March 1916 to October 1926 in reports of Department of Resources and Development, Canada, at site 3 miles downstream, are not equivalent owing to inflow from Horse 

Creek).

Gage.--Water-stage recorder. Timber control since Sept. 10, 1937. Prior to Oct. 31, 1915, 

staff gage near present site at different datum. Mar. 18, 1927, to Sept. 9, 1937, staff 

or chain gage at site 200 ft downstream at same datum.

Extremes. Maximum discharge during year, 756 cfs Apr. 28 (gage height, 7.98 ft, backwater 

from ice); maximum gage height, 11,02 ft Apr. 10 (backwater from snow and ice); no flow 

at times.

1914-15, 1927-51: Maximum discharge, 2,410 cfs (revised) Mar. 25, 1939 (gage height, 

11.40 ft, from floodmark).

Revisions.--The maximum discharge for the water year 1939 has been revised to 2,410 

cfs Mar. 25, 1939 (gage height, 11.40 ft, from floodmark), superseding figure published 

in Water-Supply Paper 876.

Remarks. Records good except those for periods of ice effect or backwater from beaver 

dams, which are poor. Several small diversions for irrigation above station.

Cooperation.--This is one of the international gaging stations maintained Jointly by the 

United States and Canada under the Boundary Waters Treaty. The records have been 

collected and compiled jointly with the Water Resources Division, Department of 

Resources and Development, Canada.

Beaver Creek near international boundary 

(international gaging station)

Location. La t 48»59i2Q", long. 105°00i40", in SW£ sec. 4, T. 37 N., R. 51 E. , 500 ft 

 downstream from Little Beaver Creek, three-quarters of a mile south of international

boundary, 6 miles northwest of Daleview, Mont., 7 miles upstream from mouth, and

7 miles east of Big Beaver customs post.

Records available. April 1949 to October 1951 (no winter records).

. Staff gage read every day or every other day during April and once weekly thereafter.

deterrainExtremes . --Maximum daily discharge during year, 1,300 cfs Apr. 30; no flow 'at times.

 1549-51: Maximum discharge, 1,400 cfs Apr. 15, 1950 (gage height, 11.1 ft, from 

floodmarks) , from rating curve extended above 320 efs on basis of slope-area determ 

ation of peak flow; but probably was higher on Apr. 30, 1951; no flow at times.

Remarks. --Records fair except those for periods of no gage-height record, which are poor.

Cooperation. --This is one of the international gaging stations maintained jointly by the 

United "States and Canada under the Boundary Waters Treaty. Records collected and compiled jointly with the Water Resources Division, Department of Resources and Development, Canada.

Rating table, Mar, 1 to Oct. 31, 1951, except periods of ice effect (gage

height, in feet, and discharge, in cubic feet per second)

194 YELLOWSTONE RIVER BASIN

Wind River at Riverton, Wyo.

Location. Lat 43°00', long. 108°22', in sec. 2, T. 1 S., R. 4 E., on right bank threequarters of a mile southeast of Riverton.

Drainage area. 2,320 sq mi, approximately.

Records available.--May 1906 to November 1908, May 1911 to September 1927, October 1928 to 

September 1951.

Gage. Water-stage recorder. Datum of gage is 4,844.38 ft above mean sea level (Wyoming 

State Highway benchmark).

Extremes.--Maximum discharge during year, 7,680 cfs June 18 (gage height, 8.13 ft); minimum daily, 270 cfs Jan. 30.

1906-8, 1911-27, 1928-51: Maximum discharge, 12,300 cfs June 14, 1906 (gage height, 

6.00 ft, estimated, site and datum then in use), from rating curve extended above 9,500 

cfs; minimum daily, 18 cfs May 14, 1948.

Remarks. Records good except those for periods of ice effect, which are fair. Diversions 

For~irrigation of about 92,000 acres above station. The major diversion began in 1926 

for the Riverton Project. Waste water, comprising most of flow in Fivemile and Muddy 

Creeks, returns to the river below the station. Some regulation by Pilot Butte Reservoir, beginning 1926, and Bull Lake Reservoir, beginning 1936 (combined capacity, 

182,000 acre-ft). Records of water temperatures and suspended sediment loads for the 

water year 1951 are given in Water-Supply Paper 1198.

Rating tables, water year 1950-51, except periods of lee effect (gage

height, In feet, and discharge, In cubic feet per second)

Yellowstone River at Miles City,, Mont.

Location. Lat 46°25 I , long. 105°51', in NW^ sec. 28, T. 8 N., R. 47 E., on left bank 50 

ft upstream from bridge on State Highway 22, three-quarters of a mile downstream from 

Tongue River.

Records available.--September 1922 to August 1923, August 1928 to September 1951.

Gage.--Water-stage recorder. Datum of gage is 2,330.20 ft above mean sea level (Montana 

State Highway benchmark). Prior to May 6, 1929, staff gages at pumping plant l£ miles 

downstream at different datums. May 6, 1929, to Sept. 30, 1931, wire-weight gage, and 

Oct. 1, 1931, to Nov. 10, 1937, water-stage recorder at present site and datum. Nov. 

11, 1937, to Sept. 30, 1946, water-stage recorder at pumping plant 1% miles downstream 

at different datum.

Average discharge. 22 years (1929-51), 10,850 ofs.

Extremes.--Maximum discharge during year, 52,000 cfs June 20 (gage height, 10.86 ft); 

maximum gage height, 12.80 ft Mar. 26 (backwater from ice); minimum daily discharge, 

2,400 cfs Feb. 5.

1922-23, 1928-51: Maximum discharge, 96,300 cfs June 19, 1944 (gage height, 12.74 

ft); maximum gage height, 14 ft Mar. 26, 1943 (ice jam), from floodmark; minimum discharge, 996 cfs Dec. 14, 1932.

Remarks. Records good except those for periods of ice effect, which are poor. Some regulation by reservoirs on tributary streams. Diversions for irrigation of about 

1,100,000 acres above station (does not include flood irrigation).

Rating tables, water year 195O-51, except .periods of ice effect (gage

height. In feet, and discharge, In cubic feet per second)

YELLOWSTONE RIVER BASIN 263

South Pork Powder River near Kaycee, Wyo.

Location.--Lat 43°37', long. 106°35', in SE^ sec. 9, T. 42 N., R. 81 W., on right bank 600 

ft upstream from bridge on U. S. Highway 87, 1-J miles upstream from Murphy Creek, 6.6 

miles southeast of Kaycee, and about 7 miles upstream from confluence with Middle Fork.

Drainage area.--1,150 sq mi, approximately.

Records available. May to December 1911 (gage heights only), April 1938 to June 1940, May 

1950 to September 1951.

Gage.--Water-stage recorder. May 11 to Dec. 31, 1911, chain gage at site 2 miles downstream at different datum. Apr. 9, 1938, to June 30, 1940, chain gage at present site 

at datum 1.90 ft lower.

Extremes. Maximum discharge during year, 4,380 cfs Sept. 7 (gage height, 5.05 ft), from 

rating curve extended above 320 cfs on basis of slope-area determination of peak flow; 

minimum, 2.2 cfs Sept. 1.

1938-40, 1950-51: Maximum discharge, 12,400 cfs July 26, 1938 (gage height, 8.80 

ft, datum then in use, from floodmarks), from rating curve extended above 61 cfs on 

basis of slope-area measurement at gage height 8.0 ft; no flow Feb. 9, 10, 1939.

Remarks.--Records fair except those above 320 cfs and those for periods of ice effect or 

no gage-height record, which are poor. Adjudications for 16 small reservoirs (combined 

capacity, 1,300 acre-ft) for storage of water above station for stock and irrigation 

use. Water rights totaling 62.4 cfs (priorities 1885-1929) for irrigation of about 

4,350 acres adjudicated for diversion above station. Records of sediment loads for the 

water year 1951 are given in Water-Supply Paper 1198.

Rating tables, water year 1950-51, except periods of ice effect (gage height, in feet, and discharge,

in cubic feet per second)

at site 50 ft upstream at datum 1.07 ft higher.

Extremes. Maximum discharge during year, 5,270 cfs Sept. 7 (gage height, 7.00 ft), from 

rating curve- extended above 1,200 cfs on basis of slope-area determination at gage 

height 8.48 ft; minimum daily, 6.8 cfs Aug. 26.

1938-40, 1950-51: Maximum discharge, 8,710 cfs July 16, 1938 (gage height, 8.48 ft, 

present datum, from floodmarks), from rating curve extended above 920 cfs on basis of 

slope-area determination of peak flow; minimum daily, 1.5 cfs Aug. 25, 1939.

Maximum stage known, about 13.6 ft, Sept. 30, 1923, from information by local 

resident.

Remarks. Records good except those above 1,200 cfs, which are fair, and those for periods 

of ice effect, which are poor. Water rights for 95 small reservoirs above station for 

storage of water for stock, irrigation, and oil production (combined adjudicated capacity of reservoirs, 5,820 acre-ft per year). Water rights (priorities 1884-1940) for 

irrigation of about 37,500 acres adjudicated for diversion above station. Records of 

sediment loads for the water year 1951 are given in Water-Supply Paper 1198.

datum. May 4, 1916, to Apr. 29, 1919, chain gage at site 17 miles downstream at different datum. May 4, 1919, to Oct. 23, 1938, chain gage at site 0.5 mile downstream at 

present datum.

Average discharge.--35 years (1916-51), 410 cfs.

Extremes. Maximum discharge during year, 3,550 cfs Sept. 8 (gage height, 5.61 ft); maximum gage height, 6.68 ft Mar. 25 (backwater from ice); no flow July 8, 9, Aug. 4, 6-10, 

25-31.

1915-51: Maximum discharge, 72,000 cfs Sept. 29, 1923 (gage height, 23.7 ft, from 

floodmarks, site then in use), from rating curve extended above 2.CUO cfs on basis of 

slope-area determination of peak flow; no flow at times during surmrers of many years.

Remarks. Records good except those for periods of ice effect, which are poor. Water 

right s for 150 small reservoirs for storage of water above station for stock, irrigation, and oil production (combined adjudicated capacity of reservoirs, 7,900 acre-ft 

per year). Water rights (priorities 1884-1940) for irrigation of about 75,000 acres 

adjudicated for diversion above station. Records of water temperatures and sediment 

loads for the water year 1951 are given in Water-Supply Paper 1198.

298 LITTLE MISSOURI RIVER BASIN

Little Missouri River at Marmarth, N. Dak.

Location.--Lat 46 °18' (revised.), long. 1D3° 54', In SE^sec. 30, T. 133 N., R. 105 W., on upstream 

side of highway bridge in Marmartli, 1-J miles downstream from Little Beaver Creek.

Drainage area.--4,570 sq mi, approximately. 

Records available.--March 1938 to September 1951.

Gage. Wire-weight gage read once daily. Prior to June 23, 1950, various wire-weight 

gages on former highway bridge 75 ft downstream at same datum.

Average discharge. 13 years, 396 cfs.

Extremes.--Maximum discharge observed during year, 4,940 cfs July 29 (gage height, 8.05 

ft); no flow Jan. 31 to Feb. 9, Mar. 3-15.

1938-51: Maximum discharge, 45,000 cfs Mar. 23, 1947 (gage height, 21.7 ft), from 

graph based on gage readings; no flow for part of most winters.

According to local residents the highest known flood occurred ir June 1907 (stage 

unknown). Other major floods occurred in March 1913, May 1929, and March 1920 and 

reached stages of about 21.5, 20.2, and 19.7 ft, respectively. (These stages are not 

comparable to stages during the period of record, owing to construction of levees).

Remarks.--Records good except those for periods of Ice effect or doubtful gage-height 

record, which are poor. Some small diversions above station for irrigation.

Revisions (water years).--W 896: 1938, 1939. W 1086: 1943, 1944.

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

Records of discharge are collected for 12 ditches that divert water from Rapid Creek 

between Canyon Lake and Farmingdale, S. Dak. Each station is equipped with a water-stage 

recorder except as noted herein. Iowa, Cyclone, Little Giant, and Lone Tree ditches are 

equipped with Parshall flumes; Lockhart ditch with a Cipolletti weir. All stations are 

located within 1 mile of ditch headgate, Water diverted by these ditches is used for irrigation of lands and stockwater on both sides of Rapid Creek in Pennington County. Records 

are collected only during the irrigation season, Apr. 1 to about 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 6 cfs, all of which returns to Rapid Creek about 1 mile downstream 

from point of diversion.

The ditches divert between gaging stations on Rapid Creek for irrigation of approximate 

acreage as follows:

Rapid Creek above Canyon Lake, near Rapid City, S. Dak.

Bennett ditch, 80 acres

Leedy ditch, 200 acres 

Rapid Creek at Rapid City, S. Dak.

392 WHITE RIVER BASIN

White River near Kadoka, S. Dak.

Location. Lat 43°45', long. 101°31', in NE^NE^ sec. 31, T. 3 S., R. 22 E., on left bank 

10 ft downstream from bridge on State Highway 73, 5 miles downstream from Cottonwood 

Creek, 6 miles south of Kadoka, and 7 miles upstream from Pass Creek.

Drainage area.--5.OOP sq mi, approximately. 

Records available.--July 1942 to September 1951.

Gage. Water-stage recorder and wire-weight gage read once daily, Prior to June 14, 1949,

wire-weight gage only at same site and datum.

Average discharge.--9 years, 325 cfs.

Extremes.--Maximum discharge during year, 21,700 cfs June 7 (gage height, 13.83 ft), from 

rating curve extended above 16,000 cfs by logarithmic plotting; minimum daily, 3 cfs 

Dec. 6-8; minimum gage height observed, 2.75 ft Oct. 22.

1942-51: Maximum discharge, that of June 7, 1951; no flow during many periods. 

Flood of June 4, 1942, reached a stage of 16.24 ft, from floodmarks (discharge, 

about 32,000 cfs, revised, from rating curve extended above 16,000 cfs). Floods of 

Mar. 8, 1905, and spring of 1927 were 1 or 2 ft higher than flood of June 4, 1942, 

from information by local residents.

Remarks.--Records fair except those 1 for periods of ice effect, which are poor. Some 

diversions above station for irrigation. Records of chemical analyses, water temperatures, and sediment loads for the water year 1951 are given in Water-Supply Paper 1198.

Rating tables, water year 1950-51, except periods of ice effect (gage height, in feet,

and discharge, in cubic feet per second)

JAMES RIVER BASIN 

James River at La Moure, N. Dak.

419

Location. Lat 46"21'20", long. 98°18'15", at northeast corner of sec. 11, T. 133 N., R. 

61 W., on left bank 80 ft downstream from bridge on State Highway 13, half a mile west 

of La Moure, and 12 miles upstream from Cottonwood Creek.

Drainage area.--5,740 sq mi, approximately (revised), of which 2,000 sq rni is probably 

noncontributing.

Records available.--April to July 1903 (gage height record only), April 1950 to September 

1951.Gage-height records 1902-11 are contained in reports of United States Weather 

Bureau.

Gage.--Water-stage recorder and rubble-masonry control. Datum of gage is 1,290.00 ft 

above mean sea level, datum of 1929. April to July 1903, staff gage at site 80 ft 

downstream at datum 4.8 ft higher. Apr. 19, 1950, to Sept. 2, 1951, wire-weight gage 

at bridge 80 ft upstream at present datum.

Extremes.--Maximum discharge during year, 2,000 cfs Apr. 8; maximum gage height, 11.45 ft 

Apr. 3 (backwater from ice); minimum discharge, 4 cfs Sept. 28 (gage height, 7.05 ft), 

result of upstream wind.

1950-51: Maximum discharge, 5,730 cfs May 16, 1950 (gage height, 15.34 ft); minimum, that of Sept. 28, 1951.

A long time local resident says above stage was the highest since 1882, with stage 

in either 1942 or 1943 being almost as high due to large ice jam.

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

Rating table, water year 1950-51, except periods of ice effect (gage 

height, in feet, and discharge, in cubic feet per second)

Location.--Lat 44°56i30", long. 97°08'50", in SW$SWjNW£ sec. 13, T. 117 N., R. 5C W., near 

center of span on upstream side of highway bridge, 1 mile downstream from inlet-outlet 

to Lake Kampeska, Z\ miles northwest of Watertown, and 8^ miles upstream from Willow 

Creek.

Records available. October 1945 to September 1951.

Gage.--Wire-weight gage read once daily. Prior to Jan. 15, 1947, staff gage at same site 

and datum.

Average discharge. 6 years, 38.9 cfs.

Extremes.--Maximum discharge observed during year, 229 cfs Apr. 7, 8; maximum gage height 

observed, 7.80 ft Mar. 29 (backwater from ice); no flow for many days.

1945-51: Maximum discharge observed, 952 cfs Apr. 13, 1947 (gage height, 8.93 ft), 

from rating curve extended above 410 cfs by logarithmic plotting; no flow for many days 

each year.

Remarks.--Records fair except those for period of ice effect, which are poor. Water is 

stored naturally offstream in Lake Kampeska (capacity, 35,500 acre-ft) during periods 

when river is rising and then naturally released, in part, when river is falling.

436 BIG SIOUX RIVER BASIN

Big Sioux River at Sioux Falls, S. Dak.

Location. Lat 43=30', long. 96°44', in S? sec. 32, T. 101 N. , R. 49 W., near center of 

span on downstream side of highway bridge, 0.25 mile downstream from Great Northern 

Railway bridge, 1 mile southwest of Sioux Falls, and 3 miles downstream from Skunk 

Creek.

Drainage area. 5,550 sq mi, approximately. 

Records available . August 1943 to September 1951.

Gage.--Wire-weight gage read once daily. Datum of gage is 1,392.83 ft above mean sea 

level, datum of 1929 (levels by Corps of Engineers).

Average discharge.--8 years, 447 cfs.

Extremes. Maximum daily combined discharge during year, 11,200 cfs Apr. 7; maximum for 

main channel only, 10,600 cfs Apr. 6 (gage height, 14.3 ft, from floodmark); maximum 

daily for bypass canal, 2,500 cfs Apr. 6; minimum daily, 6 cfs Jan. 31 to Feb. 2; minimum gage height observed, 2.27 ft Oct. 28.

1943-51: Maximum discharges, those of Apr. 6, 7, 1951; minimum daily, 4 cfs Jan. 

25 to Feb. 2, 1950; minimum gage height observed, 1.78 ft Sept. 12, 1950.

Remarks. Records good except those for periods of ice effect or flow through bypass 

canal, which are poor. During periods of extremely high stage, part of flow leaves 

channel above gage and bypasses gage through a bypass canal which returns to main 

channel at a point about 8 miles below gage. Daily discharges shown during periods 

of flow through the bypass canal are the" sum of the main channel and bypass canal discharges.
