COMPILATION OF RECORDS OF SURFACE WATERS OF

THE MISSOURI RIVER BASIN ABOVE SIOUX CITY, IOWA,

THROUGH 1950

PURPOSE AND SCOPE

This volume is one of a series of reports presenting monthly 

and yearly summaries of streamflow and reservoir data collected 

by the Geological Survey. Included with these data are, some records furnished by other Federal, State, and private agencies.

The purpose of this series of reports is to make available in 

summarized form all the surface-water records collected up to 

September 30, 1950.

The first known streamflow records to be systematically collected in the United States are those for Eaton and Madison Brooks 

in Madison County, N. Y., by John B. Jervis during 1835. Stream 

gaging by the United States Geological Survey was begun in 1888. 

At that time the Congress authorized the Irrigation Survey to be 

conducted by the Geological Survey in connection with special 

studies relating to irrigation. The work consisted of the measurements of stage and discharge of a few streams in the West. 

Since that time the work has expanded so that measurements of 

stage and discharge of streams and of stage and content of lakes 

and reservoirs have been made at more than 12, 000 gaging stations in the 48 states and the territories of Hawaii and Alaska, of 

which about 6, 400 were in operation on September 30, 1950. The 

details of the records collected at those stations are contained in 

annual reports, bulletins, and water-supply papers, which have 

been issued usually on an annual basis. Most of the records collected over the years are found only in numerous individual 

volumes, many of which are out of print and difficult to obtain.

The records have been collected mainly in cooperation with 

State, municipal and other Federal cooperating agencies and 

published in annual reports by the Geological Survey. This series 

of compilation reports has been prepared by the Geological Survey as a special project not included in the cooperative program.

2 COMPILATION OF SjURFACE WATER RECORDS, PART 6-A

The data presented in this series of reports consist of records 

of discharge of streams and contents of reservoirs summarized 

on a monthly and yearly basis. Results of miscellaneous discharge measurements and, in general, stage records have been 

excluded. Also included are bar charts showing the period of 

record covered by each gaging station and a map of the area 

showing the location of each station (pi. 1). The reports of this 

series are uniform in the type of data they contain and in the form 

of presentation.

In compiling the data for these summary reports, one important 

feature of the project was to review the analyses and computations 

originally made on the basis of all information now available. For 

some stations additional base data, obtained subsequently, allowed 

for reinterpretation and recomputation of more accurate records 

of discharge. All records were examined for major computation 

errors and tested wherever possible by comparison with records 

of discharge at other stations and weather data. Records that 

were found to be in need of substantial revision were recomputed 

or omitted if revision was not feasible. Estimates of discharge 

were made to fill short gaps to complete the continuity of the 

record, whenever practical.

Records furnished by other agencies are incorporated in these 

reports when they supplement records collected by the Geological 

Survey, and appeared consistent and reliable. Furnished records 

were reviewed in the same manner as Geological Survey records 

whenever base data were available and detailed study was feasible.

Estimates published by the Corps of Engineers in Congressional 

documents have been included herein to supplement records published by the Geological Survey for some stations, especially to 

complete water years that heretofore have been incomplete in Geological Survey reports. Some estimates that, on the basis of available data, appeared to be too uncertain and not susceptible to improvement were not compiled herein.

STREAM-GAGING PROGRAM

The area covered by this report (fig. 1) includes the Missouri 

River basin from the headwaters downstream to Sioux City, Iowa. 

It contains within its boundaries parts of the Provinces of Alberta 

and Saskatchewan and the States of Montana, Wyoming, North and 

South Dakota, Minnesota, Nebraska, and Iowa. Mostof the streams 

head in the Rocky Mountains and the general drainage direction of 

the basin is easterly to the semiarid region of the Great Plains.
STREAM-GAGING PROGRAM -5

The earliest known records of river stage in the report area are 

those for the Missouri River at Fort Benton, Mont. Gage-height 

records were collected during the summer months for the years 

1873-76, 1881-99, and 1901-9, by the Missouri River Commission, 

the Corps of Engineers, and the Weather Bureau. The Geological 

Survey began making discharge measurements at this station in 

April 1910. On the basis of a discharge curve developed from measurements made in the years that followed, daily discharge records 

were computedfrom stage records that began in 1881. .Later studies now indicate that these records prior to October 1890 may not 

he reliable and they are not included in this report.

Investigation of streamflow in the basin was begun in 1889 by the 

Geological Survey when four gaging stations were established in 

Montana on the Yellow stone River, the Gallatin River, the Sun 

River, and the Missouri River. In the decade that followed, 23 additional gaging stations were installed on these and other streams 

within the basin. The work covered in this era was largely in the 

nature of reconnassiance, exploring for the first time the potential 

value of the streams for further irrigation usage. Many of these 

records were for periods of short duration, usually for one or two 

years and for the open-water seasons only.

The period 1906 to 1910 marks the first notable expansion of the 

stream-gaging programinthe report area. Atthe close of the 19th 

century, most lands in the western States, that were susceptible 

to irrigation by private means had been reclaimed. However, interest in the irrigation movement continued to grow, with attention 

directed toward the development of the large reclamation projects 

by public financial support. In compliance with public demand, the 

Reclamation Act was passed in 1902, which led to the start of the 

Federal reclamation work and the urgent need for basic streamflow data for investigation and design of irrigation projects.

The reclamation movement had a significant effect also in stimulating interest within the western States for the protection and administration of waters under their jurisdiction and eventually led 

to the State cooperative stream-gaging programs. State cooperation 

in the report area was started by Nebraska and Wyoming in 1895, 

by North Dakota in 1901, and by Montana in 1906. Other States that 

have furnished cooperation in later years are Minnesota, Iowa, and 

South Dakota. State participation in the program has provided one 

of the principal sources of funds to sustain the work.

The Corps of Engineers, as a result of the Rivers and Harbors 

Act of 1927, and the Flood Control Acts of 1928 and 1936, supported 

expansion of the work. Beginning also in 1928, the United States 

Department of State sponsored continuing investigation of international streams that cross the Canadian border. Both programs 

have added materially to the stream-gaging activity within the area.
4 COMPILATION OF SURFACE WATER RECORDS, PART 6-A

Plans for the coordinated development of the waters of the Missouri River basin with respect to flood control, navigation, power, 

and irrigation were formulated in 1943 and 1944 by the Corps of 

Engineers, the Bureau of Reclamation, and the States in the basin. 

This plan gave a positive impetus to the growth of the stream-gaging program in the years immediately following.

Numerous municipal and private organizations have assisted 

the Geological Survey in the stream-gaging program, as have 

several bureaus of the United States government. Details of their 

cooperation have been acknowledged in the annual water-supply 

papers.

DESCRIPTION OF DATA

The gaging-station records are arranged in a downstream 

order. The order used in this report is the same as that adopted 

for use in the annual series of reports on surface-water supply 

beginning with the water year 1951. 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 on 

first rank, second rank, and other ranks of tributaries. To indicated 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 bar chart (see 

p. 16) 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 in the annual reports through the water year 1950 was different. In those reports all stations on the 

main stem are listed first in order, proceeding from the headwaters towards the mouth, then all stations on the uppermosttributary from its source to mouth, followed by all stations from 

source to mouth on the tributaries to the tributary.

The data presented for most of the gaging stations comprise a 

description of the station, tables of monthly discharge and runoff, 

and a yearly summary table. The station description gives the 

location of the gaging station, drainage area, supplemental records available (for some station), types and datums of gages, 

average discharge, extremes of discharge, and general remarks 

concerning the data. When records were furnished by another 

agency the fact is so stated.
DESCRIPTION OF DATA 5

The location of the gaging station and the drainage area are 

obtained from the best available maps. When more than one site 

was used and the difference in drainage areas is significant, the 

area for the latest site is shown first followed by the areas for 

other sites in chronological order. In some instances drainage - 

area figures have not been obtained because of the lack of suitable 

maps or because the boundaries cannot be defined or the effective 

drainage area determined.

For some stations a paragraph headed "Supplemental records 

available" gives reference to records other than those given in 

the present report. Such records may consist of gage-height records for periods other than those for which discharge records are 

presented, records concerning quality of the water, or the results 

of periodic discharge measurements.

The gage described first is the present gage or the one used 

most recently. Information is then given in chronological order 

for all gages used earlier, giving changes in location, type of 

gage, or datum. The location or datum of all earlier gages is 

given with reference to the present or most recently used gage. 

The datum of the gage is the elevation of the zero of the gage 

above mean sea level. Where information as to datum is not 

available, the altitude of the gage is given. This may be determined from topographic maps, river-profile surveys, barometric 

levels, or where nothing better is available, by estimates based 

on average fall between a known elevation and the gage or on 

other known factors. The degree of accuracy of an altitude determination is indicated by the source of the information and to some 

extent by the refinement to which the figure is given.

The average discharge for a station is the average of all complete water years and is published only if there are five or more 

complete water years of record. The years used to determine the 

average are not necessarily consecutive. The average discharge 

is not published for some stations because of extensive changes 

in diversion or storage, or other water development, that have 

occurred upstream.

In general, the momentary maximum and minimum discharges 

and stages for the entire period of record are published in the 

"Extremes" paragraph. These are qualified if necessary according 

to the type of gage used and the completeness of the record. Maximum and minimum discharges at nonrecording gaging stations 

are qualified as "observed" unless determined from a graph drawn 

through actual gage heights which approximates the actual 

hydrograph.
D COMPILATION OF SURFACE WATER RECORDS. PART 6-A

Under "Remarks" information is given on factors which affect 

the basin yield and runoff characteristics. These include upstream regulation, diversion, and utilization a history of changes 

in these items is given wher known. Also, references are made 

to the records of storage or diversion upstream, if published. 

When discharge records are furnished by another agency, credit 

is given under "Cooperation. "

The streamflow data summarized in this paper are generally 

contained in two monthly tables and one yearly table. The first 

monthly table is a tabulation of monthly and yearly mean discharge in cubic feet per second. These figures represent discharge passing the station; they are unadjusted for storage or 

diversion upstream. Each monthly figure is the mean flow for 

the entire month; generally no record for part of a month is tabulated. Likewise, each yearly figure is the mean flow for a full 

year, and no figure is shown for a partial year. Usually the 

months are arranged on a water-year basis. Exceptions to this 

rule are made in connection with seasonal records wherein the 

months are grouped to give a complete season for each calendar 

year.

The second monthly table is a tabulation of monthly and yearly 

runoff in acre-feet. The third table contains a yearly summary 

of the streamflow data. The column headed "W. S. P. no. " lists 

the number of the water-supply paper or other publication in 

which the figures of daily and monthly discharge are published; 

for early years for which daily discharges were not published, 

that column lists the report that contains daily gage heights, 

rating tables, and monthly discharge. If a part of the record has 

been revised and published, then reference is made to both the 

original report and the one containing the revised record; if the 

daily discharge record for the entire year has been republished 

to include revisions, then only the later report is listed. For 

some stations the third table is omitted; however, the report containing records for any particular year can generally be found by 

reference to the tables given on p. 10, 11.

In the third table the momentary maximum discharge for each 

water year and the date of its occurrence is given whenever obtainable. This is maximum discharge for the water year unless 

otherwise qualified. For rionrecording gage records, momentary 

maximums were often obtained from graphs drawn through the 

gage readings. If a graph was not feasible, then the discharge 

was computed from the maximum gage height observed, provided it was believed to be of significant value. The momentary 

maximum discharge is given for some years for which the record, as shown in the first two tables, is incomplete. The maximum discharge when so given is believed to be representative of
DESCRIPTION OF DATA 7

the absolute maximum of the water year and is not qualified in 

any way. Occasionally maximum daily discharges are tabulated, 

but only when it was not practicable to give momentary maximums 

and when figures may have general statistical value.

The minimum daily discharge for each water year is listed if 

known. The annual mean discharge listed in the third table is the 

same as that given in the yearly column in the first table.

Other data in this table are given for both the water and calendar year and consist of runoff in inches or in acre-feet, or both. 

These are adjusted or unadjusted for storage or diversion as the 

occasion demands, but in general no adjustments have been made 

in the West. In arid regions where the average annual precipitation is less than 20 inches, the computation of runoff in cubic feet 

per second per square mile and in depth in inches is not ordinarily made.

Most canal and diversion records are given in a single table. 

There are some records for large canals, however, that are 

published in the same detail as those for streams. Records of 

reservoirs also are given in a single table which shows the contents at the end of each month.

Figures of discharge that have been revised as the result of 

the review made in connection with this compilation are so noted; 

however, revisions that have been previously published are not 

indicated as revisions in this report. Revised daily discharges 

made in connection with this compilation will be published in a 

later annual water-supply paper. If only annual maximum discharges are revised and no revision of daily discharge is made 

for a station, revised annual maximums are given only in this report and will not be republished in a later annual report. Revisions of figures of runoff in inches resulting solely from a revision of the drainage area are not noted as such. Figures that 

represent corrections of typographical or computational errors 

where no figures of daily discharge have been revised or changed 

are indicated as "corrected" in this report. Estimated of discharge made to complete months or years for this report are 

noted as estimates and as "not previously published. "

For a few stations, after reviewing the past records, it was 

found that part of the previously published records was grossly in 

error, yet the base data were such that the record could not be 

improved or revised. For such stations a note listing the periods 

of record which have been discredited and not republished is 

given with the records published herein. Stations for which the 

entire period of record previously published has been discredited

are omitted from this report. The following table lists the stations so omitted.

In addition to the above, records for some other stations in the 

area, previously published by the Geological Survey in the annual 

series of reports, are omitted from this compilation. In general, 

the records of such stations either are too fragmentary to allow 

computation of monthly mean discharge or are records that did 

not measure streamflow, total diversion, or return flow and were 

considered not important enough to warrant publication in this report. These stations are listed in the following table:

PUBLICATIONS

To facilitate publication of streamflow records, the area of the 

United States is divided into 14 parts whose boundaries coincide 

with certain natural drainage lines. Formerly, the annual series 

of water-supply papers on the surface-water supply of the United 

States was published in 14 volumes, 1 for each of the 14 parts. 

Beginning with the reports for 1951, the records are published in 

18 volumes, including 2 volumes each for parts 1, 2, 3, and 6. 

This system is used in publishing the present series of compilation reports with the exception of part 11 which is published in 

2 volumes for the compilation report series only. The boundaries

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.
HYDRDLOGIC CONDITIONS 13

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 or other agencies. The 

more recent of these special reports also contain other pertinent 

hydro logic information and analyses and compilations of data relating to earlier notable floods. The following list gives the numbers and titles of these reports.

HYDROLOGIC CONDITIONS

Hydrologic conditions in the area covered by this report varygreatly with respect to both location and time. Figure 2 shows 

annual discharge for three streams representing different hydrologic conditions within the Missouri River basin above Sioux City, 

Iowa. The average discharge shown on the graphs is based on the 

period of record at each of the gaging stations.

The Yellowstone River is typical of streams that rise in the high 

altitudes of the Rocky Mountains. Runoff during the open-water 

season depends upon the melt of the snow, which had accumulated 

during the preceding winter. High-water runoff occurs each spring 

and early summer and then recedes to low flows, during the fall and 

winter. The low flow is augmented to a minor extent for short periods by occasional storms in the summer and early autumn.

The Belle Fourche River is typical of streams that head on the 

eastern flanks of the Rocky Mountains and in the hills of the Great 

Plains. Flow characteristics of streams reflect the transition between those of the streams rising high in the mountains and those 

of the Great Plains.

The Big Sioux River is typical of streams that drain the Great 

Plains. Most floods are due to summer storms in the four months 

from May to August, during which time about half of the annual 

rainfall occurs. Floods seldom occur during the spring breakup.
14 COMPILATION OF SURFACE WATER RECORDS, PART 6-A

The flow of many streams reported herein is affected by storage reservoirs, power developments, ground-water withdrawal and 

diversions for irrigation, and return flow from irrigated areas. 

However, natural flow conditions still prevail in most of the headwater streams.

223. Milk River at Milk River, Alberta 

(International gaging station)

Location. Lat 49°09 I , long 112°05', in SE£ sec. 28, T. 2 R. 16 W., fourth meridian, 700 

ft downstream from highway bridge, at Milk River, Alberta, and about 20 miles downstream from confluence of North and South Porks.

Drainage area.--1.104 sq mi.

Gage.--dater-stage recorder. Datum of gage is 3,402.78 ft above mean sea level (Geodetic 

Surveys of Canada datum). Prior to June 17, 1919, staff or chain gages at several 

sites about 1,000 ft upstream from present site at datum 0.61 ft higher. June 17, 

1919, to Nov. 2, 1921, water-stage recorder at site 1,000 ft upstream at datum 0.61 ft 

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

present datum.

Average discharge.--34 years (1916-50), 284 cfs.

Extremes.--1909-50: Maximum discharge, 8,730 cfs (revised) May 22, 1927 (gage height, 

11,41 ft), from rating curve extended above 4,000 cfs on basis of velocity-area study 

of peak discharge; no flow at times.

Remarks.--Since 1917 flow increased during irrigation season by water from St. Mary Canal 

(see p. 223). Several small diversions for irrigation above station.

Cooperation.--This is one of a number of stations maintained jointly by Canada and the 

United States. Records prior to Oct. 1, 1920, furnished by the Canadian Department of 

Resources and Development.

a From report of Corps of Engineers: "James and Sheyenne River basins, N. Dak. and S. Dak., Water 

Supply and Sewage Disposal."

711. James River at La Moure, N. Dak.

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

R. 61 W., at 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 (revised), approximately, of which 2,000 sq mi is probably 

noncontributing.

Supplemental records available. April to July 1903, gage heights and discharge measurements only.Gage-height records collected at same site 1902-11 are contained in 

reports of U. S. Weather Bureau.

Gage. Wire-weight gage on downstream handrail of bridge since Aug. 3, 1950. Datum of 

gage is 1,290.00 ft above mean sea level, datum of 1929. 1902 to July 17, 1910, staff 

gage at different datum. July 18, 1910, to June 30, 1911, staff gage at datum 

3.00 ft lower than 1902-10, datum (published records for period March 1909 to July 17, 

1910 are referenced to this datum). Apr. 19 to June 2, 1950, reference point on 

bridge at datum 10 ft higher than present datum (records for this period published 

in WSP 1176 are referenced to present datum).

Extremes.--1950; Maximum discharge, 5,730 cfs May 16, 1950 (gage height, 15.34 ft; 

minimum, 4 cfs Sept. 28 (gage height, 7.05 ft), result of upstream wind.

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.

Cooperation. Observations of water-surface elevations and discharge measurements prior 

to June 2, 1950, furnished by Corps of Engineers, U. S. Army.
