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, 1957. 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 13,750 gaging stations in the 48 States and at many others in 

the Territories of Alaska and Hawaii. On September 30, 1957, the Geological Survey and 

cooperating organizations were maintaining 7,030 gaging stations, including those in 

Alaska and Hawaii. Discharge measurements only were made at many other points in the 

1957 water year. The name of each stream measured at points other than gaging stations 

is not listed in the index to this report. Only the major river basins in which measurements were made are listed under the item "Discharge measurements" in the index.

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 usi.ally 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 stagedischarge relation at the gage. This feature may be a natural constricticn of the 

channel, a long reach of the channel, or an artificial 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 if that area, measured in a horizontal plane, which is so enclosed by a topographic divide that direct r-urface runoff from 

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

Figures of drainage area given herein include all clossd basins, or noncontributing areas, 

within the area unless otherwise noted.

WSF is used as an abbreviation for "Water-Supply Paper" in reference to previously published reports.

DOWNSTREAM ORDER OF LISTING GAGING STATIONS

Beginning with the series of reports for the water year ending September 3 , 1951, the 

order of listing gaglng-station records was cnanged. 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 listed between them. A similar order is followed in listing stations en first rank, 

second rank, and othsr 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 tills report 

represents one rank. This 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 8 

nonrecording gage or from a water-stage recorder that gives a continuous record of fluctuations . Measurements of discharge are made with a current meter bj 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 

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

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

EXPLANATION OF DATA 5

continual change in the physical features that form the control, the daily mean discharge 

is determined by the shifting-control method, iti 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. 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 in 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 so-ne 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. Records are published for the water year which begins on October 1 

and ends on September 30. A calendar for the water year 1957 is shown on page IV for the 

purpose of finding the day of the week for any date.

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 "Records available" are given the periods 

for which there are published records generally equivalent to those at the present site. 

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, locations, and datums of previous gages used during the period of records available. 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 ctanges 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 (urless it is 

of no importance). In the first paragraph, the data given are for the complete current 

water year unless otherwise specified. In the second paragraph, the data given are for
6 SURFACE WATER SUPPLY, 1957, PART 6-A

the periods of record within the calendar year dates in the heading (not necessarily 

those for the complete years indicated by the heading dates). Reliable information concerning major floods that have occurred outside the period of record are given in the 

third or last paragraph under "Extremes." Unless otherwise qualified, the maximum discharge corresponds to the crest stage obtained by use of a water-stage recorder, a creststage 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."

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 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 fie 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. Skeleton rating tables are generally 

not published for stations on canals.

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 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 corresponding to once-daily readings of the gage, or to the mein 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.
EXPLANATION OF DATA 7

In the table of daily discharge, the figures for the maximum day and the minimum day 

for each month are underlined. If the figure 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 figures; it is the total cfs-days for the month. The line headed "M3an" 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"). Figures for cubic feet per 

second per square mile and runoff in inches are omitted if the drainage area includes 

large nonoontribufcing 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 figures of maximum are the maximum 

daily discharges, not the momentary discharges when the water was at crest sta.se. 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 published each year for all reservoirs for which records are published on a 

daily basis, but it is not published for reservoirs for which only monthly data are given.

Discharge measurements and determinations of peak flows made at sites other than gaging 

stations are listed at the end of each report.

At many gaging stations water samples are collected from the streams for the purpose 

of making chemical analyses, computing dissolved solids, suspended sediment loads, and 

particle-size distribution, or measuring water temperatures. For most of these samples 

the results are published in -an annual series of water-supply papers entitled "Quality 

of Surface Waters of the United States" which is Issued in four volumes. In this report 

under "Remarks" a reference is made to quality-of-water records collected at gaging stations on a regular basis and published in the quality-of-water reports. At many other 

gaging stations quality-of-water data are obtained at irregular intervals and published 

as "miscellaneous analyses" in quality-of-water reports; such records are not referred to 

in "Remarks" paragraph in this report. At many gaging stations water temperature is obtained also at the time a discharge measurement is made; such temperature readings are not 

reported in the quality-of-water annual reports.

ACCURACY OP 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, figures 

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.

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 publications 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.

PUBLICATIONS 11

The records at most of the stations discussed in these reports extend over many years. 

Discharge measurements at many points other than regular gaging stations have been made 

each year and are published 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 WaterSupply 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.

RECORDS OF DISCHARGE COLLECTED BY AGENCIES OTHER THAN THE GEOLOGICAL SURVEY

Records of daily discharge for South Cottonwood Creek near Gallatin Gateway and Rocky 

Creek (East Gallatin River) near Boseman, Mont., have been collected by Montana State 

College, Civil Engineering Department, since 1954.

HYDROLOOIC CONDITIONS

Runoff was below median at the outset of this year and remained so during November except in North Dakota and South Dakota when general rains and melting snow caused runoff 

considerably above median. During December streamflow in Nebraska was entirely groundwater effluent and small streams in northern Nebraska have shown a considerable decrease 

In base flow the past 3 years. Runoff continued near or below median during the period 

January to April throughout the area. A slight increase in runoff occurred in streams in 

South Dakota following the general rains of Apr. 18-20. Streamflow continued at or below 

median in Wyoming and Montana during May, even though prairie streamflow increased 

slightly in Montana as the result of general rains May 19-21, and was well above median 

in the Dakotas. Minor flooding occurred along Sun River in Montana through the combined 

effect of snowmelt and rains, and runoff west of the Missouri River in South Dakota was 

excessive in Moreau, Cheyenne, Bad, and White River basins; peak discharges were below 

maximum of record, but were the highest in several years. Maximum discharge of record 

occurred on White River below Cottonwood Creek near Whitney, Nebr. during the flood of 

May 20, 1957; a gage height of 20.1 ft was reached with a corresponding discharge of 

4,500 cfs. Some western tributaries of the Missouri River in North Dakota reached bankfull stages following the storm of June 21-22 when 6 inches of rain fell near Amidon. 

Floods occurred in the southeastern part of South Dakota as a result of the storm of 

June 16-17 when as much as 11 inches of rain fell in slightly more than 24 hours in 

some areas and 4 inches fell over most of the area. Peak stages of Skunk Creek and Big 

Sioux River were the highest known according to local residents. Flooding occurred in 

the Yankton, Sioux Falls, Dell Rapids, and Flandreau areas; 5 persons drowned and property damage was heavy. An outstanding flood on Baaille Creek near Niobrara, Nebr. occurred June 16. The flood reached a stage about 4.0 ft higher than any flood in recent 

years. Record June flows occurred at some points in the upper Missouri and Yellowstone 

River basins in Montana. Runoff remained fairly high in July and was above median 

throughout all the area. Runoff continued above median during August and September except in Montana where it was below. For three key gaging stations in the area covered 

by this report a comparison of monthly and yearly mean discharges for the 1957 water 

year with the median discharges for the 25-year period (1921-45) is shown in figure 3 

on opposite page.

Missouri River at Fort Benton, Mont.

Location (rev ised) . Lat 47°49'03", long 110°39'59", in SE^-SE^ sec. 23, T. 24 N. , R. 8 E., 

on left ba.nk at downstream side of highway bridge at Fort Benton, 4 miles upstream

from Shonkin Creek.

Drainage area. 24,600 sq mi, approximately.

Records available. October 1890 to September 1957. Records for June 1881 to September 

1890, published in WSP 546 and 761, have been found to be unreliable and should not be

used.

Gage. Water-stage recorder. Datum of gage is 2,614.05 ft above mean sea level, datum

of 1929. Prior to Oct. 11, 1921, several types of manually operated gages, and Oct. 11, 

1921, to Apr. 25, 1924, water-stage recorder, all at present site and at datum 1.00 ft 

higher.

Average discharge.--67 years, 7,613 cfs (5,512,000 acre-ft per year).

Extremes. Maximum discharge during year, 21,400 cfs May 22 (gage height, 6.25 ft); maximum gage height, 13.25 ft Dec. 9 (backwater from ice); minimum daily discharge, 

3,000 cfs Dec. 6.

1890-1957: Maximum discharge observed, about 140,000 cfs June 6, 1908 (gage height, 

18.5 ft, present datum), from rating curve extended above 63,000 cfs; minimum, 320 cfs 

July 5, 1936 (gage height, -0.50 ft); minimum daily, 627 cfs July 5, 1936.

Remarks.--Records good except those for periods of ice effect, which are fair. Diversions for irrigation of about 730,000 acres above station. Extreme diurnal fluctuation caused by powerplant at Morony Dam. Flow regulated by 18 smaller irrigation 

reservoirs and powerplants (see p. 24l), and Canyon Ferry Reservoir (see p. 44).

bank 400 ft south of international boundary, 500 ft downstream from Canada Coulee, 

30 miles north of Rudyard, Mont., and 37 miles south of Many Berries, Alberta.

Drainage area. 2,514 sq mi.

Records available.--August 1909 to September 1957 (few winter records).

Gage. Water-stage recorder and rock control. Datum of gage is 2,698.4 f", above mean sea 

level (International Boundary Survey datum). Prior to Aug. 13, 1913, staff gages at 

several sites within a quarter of a mile of present site at various daturas. Aug. 13, 

1913, to June 13, 1917, water-stage recorder and staff gages at site 200 ft downstream 

on left bank at datum 2.34 ft lower.

Extremes. Maximum discharge during year, 1,380 cfs May 10 (gage height, 2.61 ft); maximum 

gage height, 5.66 ft about Mar. 2 (backwater from ice, from floodmark); minimum daily 

discharge determined, 50 cfs Oct. 31; probably no flow at times during winter period.

1909-1957: Maximum discharge, 9,530 cfs Mar. 31, 1952 (gage height, 9.34 ft), from 

rating curve extended above 2,600 cfs, but may have been higher Mar. 28, 1952; maximum 

gage height, 13.65 ft Mar. 28, 1952 (backwater from ice); no flow at times.

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

which are poor. Since 1917 flow increased during irrigation season by discharge of 

St. Mary Canal (see p. 88). Small diversions for irrigation above station.

Cooperation. This is one of a number of stations which are maintained Jointly by the 

united States and Canada.

MILK RIVER BASIN 93

Gag,

Milk River at Havre, Mont.

Location. Lat 48°33'30", long 109°40'10", in SE&SEi sec. 5, T. 32 N., R. 16 E. , on upstream side of highway bridge on 7th Avenue East in Havre, 30 ft downstream from Bull 

Hook Creek, 9 miles downstream from Big Sandy Creek, and 17 miles downstream from 

Presno Dam.

Records available. May 1898 to September 1922 (no winter records), August 1954 to 

September 1957.

. Wire-weight gage read twice daily. Datum of gage is 2,461.11 ft above mean sea 

"evel, datum of 1929 (levels by Corps of Engineers). Prior to Nov. 2, 1902, wireweight gage at site half a mile upstream at different datum. Nov. 4, 1902, to 

Nov. 25, 1910, chain gage at datum 0.47 ft higher, Mar. 9, 1911, to July 13, 1920, 

chain gage at present datum, and July 14, 1920, to Sept. 30, 1922, chain gage at 

datum 4.00 ft higher, all at site 30 ft downstream.

Average discharge. 17 years (1899-1916), prior to operation of St. Mary Canal, 273 cfs 

(197,600 acre-ft per year); 6 years (1916-22), 336 cfs (243,300 acre-ft per year).

Extremes. Maximum discharge observed during year, 1,280 cfs July 26 (gage height, 

9.81 ft); minimum daily, 20 cfs Jan. 23-26.

1898-1922, 1954-57: Maximum discharge, about 20,000 cfs Apr. 12, 1899 (gage height, 

19.3 ft, present datum, from floodmarks), from rating curve extended above 5,200 cfs 

by logarithmic plotting; no flow at times in several years.

Flood of Apr. 3, 1952, reached a stage of 18.6 ft (discharge, about 11,400 cfs).

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

Hook Creek flood-control project is designed to bypass damaging floods to Milk River 

channel several miles downstream. Diversions for irrigation of about 6,000 acres 

above station. Since 1917, flow increased during irrigation season by water from 

St. Mary Canal which diverts from the St. Mary River near Babb (see p. 88). Plow 

regulated by Presno Reservoir which was completed in 1939 (see p. 241).

94 MILK RIVER BASIN

Lodge Creek below McRae Coulee, at international boundary 

(International gaging station)

Location. Lat 49°00'20", long 109°43'05", in SW£ sec. 5, T. 1, R. 28 W. , third meridian, 

in Saskatchewan, on right bank a quarter of a mile downstream from McRae Coulee, 

0.4 mile north of international boundary, three-quarters of a mile northeast of 

Willow Creek customs post, and 31 miles north of Havre, Mont.

Drainage area. 850 sq mi, approximately.

Records available. October 1951 to October 1957 (seasonal records only). Prior to October 1951, records were collected on both McRae Coulee and Lodge Creek above McRae 

Coulee. Summations are equivalent to records at this site.

Gage.--Water-stage recorder. Datum of gage is 2,731.0 ft above mean sea level (International Boundary Survey datum).

Extremes. Maximum discharge observed during season, 796 cfs Apr. 5 (result of discharge 

measurement); maximum gage height, 6.71 ft Apr. 5 (backwater from ice); no flow at 

times.

1951-57: Maximum discharge, 5,570 cfs (includes inflow from Battle Creek drainage) 

Apr. 13, 1952 (gage height, 12.50 ft); maximum gage height, 12.73 ft A^r. 7, 1952 

(backwater from ice); no flow at times in each year.

Maximum discharge determined at this site, about 5,700 cfs Mar. 30, 1943, on basis 

of records for Lodge Creek at international boundary and McRae Coulee at international 

boundary.

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

which are poor. Natural flow affected by storage reservoirs, diversions for irrigation and return flow from irrigated areas.

Battle Creek at international boundary 

(International gaging station)

Location. Lat 49°00'10", long 109°25'20", in SE£ sec. 4, T. 1, R. 26 W. , third meridian, 

on left bank 600 ft north of international boundary in Saskatchewan, 8 miles upstream 

from Woodpile Coulee, and 30 miles north of Chinook, Mont.

Drainage area. 726 sq mi.

Records available. April 1917 to October 1957 (seasonal records only most years).

Gage.--Water-stage recorder. Datum of gage is 2,729.8 ft above mean p sea level (International Boundary Survey datum).

Extremes. Maximum daily discharge during season, 655 cfs Apr. 1; maximum gage height, 

6.84 ft Apr. 1 (backwater from ice); minimum discharge, 0.5 cfs Sept. 8, 9.

1917-57; Maximum discharge, 5,820 cfs Apr. 15, 1952 (gage height, 10.56 ft); no 

flow at times during most years.

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

record, which are poor. Natural flow of stream affected by storage reservoirs, diversions for irrigation and return flow from irrigated areas. Water may be diverted into 

or from Frenchman River basin through Cypress Lake. Peak discharge for 195? affected 

by loss to Lodge Creek basin (see records for Battle Creek above Cypress Lake west 

inflow canal, near West Plains, Saskatchewan).

Cooperation. This is one of a number of stations which are maintained Jointly by Canada 

and the United States.

(International gaging station)

Location. Lat 49 C00'00", long 107°18'10", in SEjJ- sec. 5, T. 1, R. 10 W., third meridian, 

on left bank 50 ft upstream from international boundary and 22 miles northeast of 

Whitewater, Mont.

Drainage area. 2,020 sq mi, approximately.

Records available. April 1917 to October 1957 (seasonal records only most years).

Gage. Water-stage recorder and concrete control. Altitude of gage is 2,420 ft (from 

Topographic map). Prior to June 23, 1937, at site about half a mile upstream at 

different datum, and June 23, 1937, to October 1952, at site 100 ft downstream at 

present datum.

Extremes. Maximum discharge during season, 558 cfs Apr. 13 (gage height, 6.20 ft); no 

flow Aug. 24 and part of Aug. 25.

1917-57: Maximum discharge, 22,700 cfs Apr. 15, 1952 (gage height, 19.90 ft, from 

floodmark), from rating curve extended above 2,300 cfs on basis of slope-area 

determination of peak flow; no flow at times during most years.

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

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

irrigation, and return flow from irrigated areas. Water may be diverted into or from 

Battle Creek basin through Cypress Lake.

Cooperation. This is one of a number of stations which are maintained Jointly by Canada 

and the United States.

Extremes . --Maximum discharge during year, 520 cfs May 12; maximum gage height, 4.00 ft 

May 12; no flow Jan. 18 to Feb. 23.

1945-57: Maximum discharge, 593 cfs June 22, 1948 (gage height, 4.97 ft, present 

datum), from rating curve extended above 150 cfs; no flow at times during 1950-57.

Correction. The figures of maximum discharges for water years 1949 and 1950 as 

revised in WSP 1209 should not have been made; figures as originally published are 

correct .

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

which are poor. Many small diversions for irrigation of hay meadows above station.

Correction . The figures of supplemental peak discharges for water year 1950 as revised 

1209 should not have been made; figures as originally published are correct.

upstream from Five Springs Creek and 6^ miles south of Kane.

Drainage area .--IS .900 sq mi, approximately. 

Records available.--August 1928 to September 1957.

Gage. Water-stage recorder. Altitude of gage is 3,660 ft (from Fairchild Aerial Survey 

map made for the U. S. Bureau of Reclamation). Prior to Apr. 25, 1932, chain gages on 

highway bridge 12^ miles downstream at different datums. Apr. 25, 1932, to Nov. 25, 

1943, water-stage recorder 150 ft upstream from bridge at different datum. Nov. 26, 

1943, to May 16, 1956, water-stage recorder 26 ft downstream from bridge at different 

datum.

Average discharge. 29 years, 2,308 cfs (1,672,000 acre-ft per year).

Extremes. Maximum discharge observed during year, 14,200 cfs June 7 (gage height, 

7.24 ft); minimum daily, 836 cfs Apr. 22.

1928-57: Maximum discharge, 25,200 cfs June 16, 1935 (gage height, 11.10 ft, site 

and datum then in use); minimum daily, 179 cfs July 22, 1934.

Maximum stage known, 14.8 ft Sept. 30, 1923, site and datum then in use.

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

which are fair. Diversions for irrigation of about 275,000 acres above station. 

Some regulation by Boysen Reservoir since October 1951(see p. 240). Records of 

chemical analyses, water temperatures and suspended sediment loads for the water year 

1957 are given in WSP 1521.

Correction. Daily mean discharge for June 16, 1929, was 7,980 cfs and that fcr June 19, 

1929, was 11,500 cfs, superseding erroneous figures published in WSP 686.

bank just downstream from bridge on U. S. Highway 10, three-quarters of a mile upstream 

from mouth, 1 mile southwest of Bighorn, and 4 miles east of Custer.

Records available.--May 1945 to September 1957. Published as "near Custer" 1945-55.

Gage. Water-stage recorder. Altitude of gage is 2,690 ft (by barometer). May 11 to

Dec. 6, 1945, wire-weight gage and Dec. 7, 1945, to Oct. 6, 1955, water-stage recorder, 

at site 4 miles upstream at different datum.

Average discharge.--12 years, 3,858 cfs (2,793,000 acre-ft per year).

Extremes.--Maximum discharge during year, 20,800 cfs July 3 (gage height, 8.78 ft); maximum gage height, 8.95 ft June 18 (backwater from Yellowstone River); minimum daily 

discharge, 1,400 cfs Jan. 29; minimum gage height, 1.91 ft Apr. 16.

1945-57: Maximum discharge, 26,200 cfs June 24, 1947 (gage height, 8.79 ft, site 

and datum then in use), from rating curve extended above 12,500 cfs by logarithmic 

plotting; maximum gage height recorded, 10.65 ft Mar. 20, 1947 (ice jfrn), site and 

datum then in use; minimum discharge, 756 cfs Dec. 13, 1949 (gage height, 0.89 ft, 

site and datum then in use).

Remarks Records good except those for period of ice effect, which are poor. Major 

regulation by 14 reservoirs in Wyoming and 1 in Montana with combined usable storage 

of about 1,400,000 acre-ft (for records of storage in Buffalo Bill and Boysen Reservoirs and Bull Lake see p. 240). Diversions for irrigation of about 465,000 acres 

above station. Records of chemical analyses, water temperatures, and suspended 

sediment loads for the water year 1957 are given in WSP 1521.

at present site at same datum. June 23, 1950, to Sept. 2, 1957, wire-weight gage at 

site 90 ft upstream, read once daily.

Average discharge. 19 years, 346 cfs (250,500 acre-ft per year); median of yearly mean 

discharges, 290 cfs (210,000 acre-ft per year).

Extremes. Maximum discharge during year, 6,890 cfs Apr. 22 (gage height, 8.66 ft); no 

flow at times.

1938-57: Maximum discharge, 45,000 cfs Mar. 23, 1947 (gage height, 21.7 ft); maximum gage height, 23.4 ft Mar. 31, 1952 (backwater from ice); no flow for part of most 

years.

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

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

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

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

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

Beaver Creek at Wibaux, Mont.

Location. Lat 46°59', long 104° 11' , in NE£ seo. 12, T. 14 N., R. 59 E., on upstream side 

of bridge on U. S. Highway 10 at Wibaux, 12 miles upstream from Little Beaver Creek.

Records available.--April 1938 to September 1957.

Gage.--Wire-weight gage read once daily and orest-stage indicator. Altitude of gage is 

2,650 ft (by barometer). Prior to Sept. 21, 1940, staff or wire-weight gages at sites 

about 500 ft upstream at different datums.

Average discharge.--19 years, 24.1 ofs (17,450 acre-ft per year).

Extremes. Maximum daily discharge during year, 150 cfs Mar. 22; no flow at times.

T9~38-57 : Maximum discharge, 3,780 cfs Mar. 21, 1939 (gage height, 10.8 ft, site and 

datum then in use, from graph based on gage readings), from rating curve extended above 

2,400 cfs; maximum gage height observed, 13.44 ft Mar. 24, 1943 (ice jam); no flow at 

times.

Flood of June 7, 1929, reached a discharge of about 30,000 cfs, from the average of 

three indirect determinations made at different sites. Flow of 1872 reported similar 

in magnitude. Flood of June 1921 reached a stage about 8.6 ft lower than 1929 (discharge, about 10,000 cfs, estimated on basis of cross-section and information from 

local resident).

Revisions. The figures of maximum discharge for some water years have been rerevised, as shown in the following table. They supersede those published in the watersupply papers indicated.

Average discharge.--13 years (1944-57), 25.8 cfs (18,690 acre-ft per year).

Extremes. Maximum discharge during year, 1,440 cfs June 11 (gage height, 11.41 ft); no 

flow Oct. 1, 2, Sept. 3, 4, 9-12, 20-30.

1943, 1944-57: Maximum discharge observed, 1,840 cfs Mar. 27, 1943 (gage height, 

14.0 ft, from floodmark); no flow at times in 1943, 1945, 1950, 1952-57.

Remarks. Records good except those for period of ice effect, which are poor. Discharge 

measurements generally made three times a month prior to April and once a wesk during 

the rest of year. Diversions above station for irrigation (for details on adjudication of diversions, see Remarks for this station in WSP 1209). There are 1,350 small 

reservoirs above station used for storage of stock and irrigation water (total capacity, about 11,000 acre-ft). Records of water temperatures and suspended sediment 

loads for the water year 1957 are given in WSP 1521.

Revisions (water years). WSP 1209: 1943, 1946, 1948-49.

Spearfish Creek at Spearfish, S. Dak.

Location.--Lat 44°29'00", long 103°51'15", in SE^NW^ sec. 15, T. 6 N., R. 2 E., on right 

bank in city park in Spearfish, 300 ft downstream from fish hatchery and nearest tributary and 12 miles upstream from mouth.

Drainage area.--168 sq mi.

Records available. October 1946 to September 1957.

Gage. Water-stage recorder. Altitude of gage is 3,640 ft (from topographic map). Prior 

Co Dec. 5, 1946, staff gage at same site and datum.

Average discharge. 11 years, 44.9 cfs (32,510 acre-ft per year).

Extremes.--Maximum discharge during year, 158 cfs July 14 (gage height, 5.22 ft); maximum 

gage height, 6.94 ft Jan. 25 (backwater from ice); minimum discharge, 9 cfs Nov. 3 

(gage height, 4.12 ft); minimum daily, 18 cfs Oct. 1.

1946-57: Maximum discharge, 947 cfs May 22, 1952 (gage height, 6.81 ft); maximum 

gage height, 7.29 ft Jan. 24, 1952 (backwater from ice); minimum discharge, 7 cfs 

Mar. 14, 1948; minimum daily, that of Oct. 1, 1956; minimum gage height, 3.89 ft 

Dec. 17, 1946.

Flood of June 5, 1904, reached a stage of 7.00 ft, site and datum of former gage 

near Spearfish, 1 mile upstream (drainage area, 157 sq mi); discharge, about 5,000 cfs.

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

which are fair. Regulation by fish hatchery and by hydroelectric plant half a mile upstream causes diurnal fluctuation, but since storage capacity is small, daily flows 

are not affected appreciably.

1929-57: Maximum discharge, 440,000 cfs Apr. 10, 1952 (gage height, 25.35 ft); minimum daily, 2,300 cfs Nov. 14-16, 1940; minimum gage height observed, 0.20 ft Nov. 27,

Remarks. Records excellent except those for period of ice effect, which ere good. Discharge measurements generally made twice a week during open water and once a week during winter period. Many diversions above station for irrigation. Flow regulated by 

Garrison Reservoir (see p. 254). Records of chemical analyses and water temperatures 

for the water year 1957 are given in WSP 1521.

JAMES RIVER BASIN 375

James River at La Moure, N. Dak.

Location. Lat 46°21 I 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, 1-alf a mile 

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

Drainage area. 5,740 sq mi, approximately, of which about 8,800 sq mi is probably noncontributing.

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

1957.Gage-height records 1902-11 are contained in reports of U. S. 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. 1902-8, 1909-11, staff gages at site 80 ft upstream at two different datums. Apr. 19, 1950, to Sept. 2, 1951, wire-weight gage 

on bridge 80 ft upstream at present datum.

Average discharge.--7 years (1950-57), 71.1 cfs (51,470 acre-ft per year).

Extremes. Maximum discharge during year, 82 cfs Mar. 31 (gage height, 7.59 ft); no flow 

part of Oct. 24, Aug. 6, result of upstream wind.

1950-57: Maximum discharge, 5,730 cfs May 16, 1950 (gage height, 15.34 ft); no 

flow for part of each day Sept. 30, Oct. 24, 1956, Aug. 6, 1957.

A long time local resident says flood of May 16, 1950, was the highest since 1882, 

with stage in either 1942 or 1943 being almost as high due to large ice ja-n.

Remarks. Records good above 20 cfs and fair below. Flow regulated by Arrowood and 

Jim Lakes and Jamestown Reservoir (combined capacity, 246,000 acre-ft).

Revisions. WSP 1209: Drainage area.

downstream at about same datum. Mar. 16, 1929, to Apr. 27, 1930, U. S. Weather Bureau 

staff gage and Apr. 28, 1930, to June 30, 1932, chain gage on highway bridge at 

present datum. Aug. 3, 1943, to Oct. 17, 1951, staff gage at site 15 ft downstream at 

present datum (u. S. Weather Bureau staff or wire-weight gage on highway bridge used 

as supplementary high-water gage).

Average discharge.--15 years (1930-31, 1943-57), 238 cfs (172,300 acre-ft per year); 

median of yearly mean discharges, 170 cfs (123,000 acre-ft per year).

Extremes. Maximum discharge during year, 674 cfs May 26 (gage height, 8.52 ft); no flow 

for many days.

1928-32, 1943-57: Maximum discharge, 5,580 cfs Apr. 15, 1952 (gage height,

VERMILLION RIVKR BASIN 391

Vermillion River near Wakonda, S. Dak.

Location. Lat 42°59'20", long 96 057'50", in SW^NW^ sec. 2, T. 94 N., R. 52 VI., on left 

bank 40 ft downstream from bridge on State Highway 19, 3| miles downstream from Frog 

Creek, 7-j miles southeast of Wakonda, and 16^ miles downstream from Turkey Ridge Creek.

Drainage area. 1.680 sq mi, approximately. 

Records available. October 1945 to September 1957.

Gage. Water-stage recorder. Datum of gage is 1,150.9 ft above mean sea level (levels by 

ETorps of Engineers). Prior to Sept. 2, 1954, wire-weight gage and crest-stage indicator at site 40 ft upstream at same datum. Since Dec. 27, 1951, supplementary staff 

gage on relief bridge.

Average discharge . 12 years, 125 cfs (90,500 acre-ft per year).

Extremes. Maximum discharge daring year, 2,990 cfs June 21 (gage height, 16.48 ft); no 

flow for many days.

1945-57: Maximum discharge, 3,790 cfs June 21, 1954 (includes 1,850 cfs bypass flow 

from levee breaks); maximum gage height, 16.63 ft June 13, 1947, from graplr based on 

gage readings; no flow at times during 1951, 1956-57.

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

which are poor. At times during periods of high stage, part of flow leaves main channel through levee breaks and bypasses gage through two relief openings on left bank. 

Discharge measurements generally made every two weeks during winter and weekly during 

remainder of year.

392 BIG SIOUX RIVER BASIN

Big Sioux River at Water-town, S. Dak.

Location. Lat 44°56'30", long 97°08'50", in SW£SW£NW£ sec. 13, T. 117 N., R. 53 W., near 

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

to Lake Kampeska, similes northwest of Watertown, and &| miles upstreati from Willow 

Creek.

Drainage area. 1,800 sq mi, approximately, of which about 1,400 sq mi is probably noncontributing.

Records available. October 1945 to September 1957.

Gage. Wire-weight gage read once daily; crest-stage indicator since Mar. 3, 1953. Alti- 

"ifude of gage is 1,710 ft (from river-profile map). Prior to Jan. 15, 1947, staff gage 

at same site and datum.

Average discharge . 12 years, 38.1 cfs (27,580 acre-ft per year).

Extremes Maximum discharge during year, 304 cfs May 26 (gage height, 6.51 ft); maximum 

gage height, 6.56 ft Mar. 21 (backwater from ice); no flow Jan. 13 to F?b. 24.

1945-57: Maximum discharge observed, 2,220 cfs Apr. 9, 1952; maximum gage height 

observed, 10.35 ft Apr. 4, 1952 (backwater from ice); no flow for many days each year.

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

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.

Note. Stage-discharge relation affected by ice Nov. 16 to Mar. 25.
396 BIG SIOUX RIVER BASIS

Big Sioux River at Sioux Palls, S. Dak.

Location.--Lat 43°30', long 96°44', in Sj sec. 32, T. 101 N., R. 49 W., 01 left bank 5 ft 

downstream from highway bridge, 0.25 mile downstream from Great Northern Railway 

bridge, 1 mile southwest of Sioux Palls, and 3 miles downstream from Skunk Creek,

Drainage area.--5,750 sq mi, approximately, of which about 1,970 sq mi is probably noncontributing.

Records available. August 1943 to September 1957

Gage. Water-stage recorder. Datum of gage is 1,392.83 ft above mean sea level, datum 

of 1929 (levels by Corps of Engineers). Prior to Sept. 11, 1954, wire-weight gage and 

crest-stage indicator at same site and datum. Since Mar. 4, 1953, wire-weight gage on 

bypass canal.

Average discharge.--14 years, 410 cfs (296,800 acre-ft per year).

Extremes. Maximum combined discharge during year, 16,200 cfs June 17; maximum for main 

channel only, 16,100 cfs June 17 (gage height, 16.01 ft); maximum for bypass canal, 

2,820 cfs June 19 (gage height, 14.26 ft, from floodmark); minimum daily, 2.5 cfs 

Feb. 6, 7; minimum gage height, 1.59 ft Jan. 1.

1943-57: Maximum discharges, those of June 17, 19, 1957; minimum, 0.4 cfs Sept. 15, 

1955 (gage height, 1.43 ft).

Remarks.--Records good except those for period of ice effect, which are poor. During

periods of 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.

Revisions [water years).--WSP 1086: Drainage area. W3P 1146: 1948 (maximum gage height 

only).

Rating table, water year 1956-57, except period of ice effect or bypass flow (gage 

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

Extremes.--Maximum discharge during year, 606 cfs July 4 (gage height, 12.00 ft); no flow

for many days.

1948-57: Maximum discharge, 10,900 cfs June 7, 1953 (gage height, 17.57 ft), from

rating curve extended above 860 cfs on basis of contracted-opening determination of

peak flow; no flow for many days in some years.

Flood in September 1926 reached a stage of 18.0 ft (discharge not determined) and

flood in 1934 reached a stage of 15.8 ft (discharge not determined), f-om information

by Iowa Highway Commission. 

Remarks.--Records fair except those below 10 cfs and for periods of ice effect, which are

poor.

434 DISCHARGE MEASUREMENTS AT POINTS OTHER THAN GAGING STATIONS

Measurements of streamflow in the Missouri River basin above Sioux City, Iowa, made at 

points other than regular gaging stations are given in the following table. Most of these 

measurements were made during periods of base flow when streamflow is primarily from 

ground-water storage. Measurements believed to have been made under base-flow conditions 

are identified by an asterisk (*) to the left of the discharge figure. These measurements when correlated with the simultaneous discharge of a nearby stream where continuous 

records are available will give a picture of the low-flow potentiality of stream. The 

column headed "Measured previously shows the water years in which measurements were made 

at the same, or practically the same, site.

Determinations of peak flow at points other than regular gaging stations are given in 

a separate table on page 445.
