COMPILATION OF RECORDS OF SURFACE WATERS OF

HUDSON BAY AND UPPER MISSISSIPPI RIVER BASINS,

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 of 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 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 contents 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 SURFACE WATER RECORDS, PART 5

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.

STREAM-GAGING PROGRAM

The area covered by this report (fig. 1) consists of the part of 

the Hudson Bay basin that is within the United States and of the 

Upper Mississippi River basin. The latter basin includes all western tributaries down to, but excluding, the Missouri River and all 

eastern tributaries down to, but excluding, the Ohio River.

Demands for irrigation in Montana, navigation on the Mississippi River downstream from St. Paul, Minn,, and on the Red River 

of the North, waterpower development in Wisconsin, and flood control in Illinois are some of the reasons for the establishment of 

gaging stations shortly after 1900.

The Corps of Engineers made discharge measurements on the 

Mississippi River in Minnesota and Iowa as early as 1866. Navigation requirements led to the establishment of stage stations on 

the Mississippi River at Le Claire, Iowa, in 1873; Keokuk, Iowa, 

in 1878; some of the tributaries upstream from St. Paul in the
STREAM-GAGING PROGRAM 3

1880's and 1890's; and on Red River of the North at Grand Forks, 

N. Dak., in April 1882.

Gaging stations were established by the Geological Survey in 

North Dakota in 1901; in Illinois, Montana, and Wisconsin in 1902; 

and in Iowa, Indiana, Minnesota, and Missouri in 1903. Cooperation between the Geological Survey and the States in the basins 

started in North Dakota in 1901. Between 1901 and 1913, cooperative programs were instituted with all the other states in the area. 

Most of the cooperative programs were intermittent in the early 

years.

The water-resources investigation of the basins were aided by 

the passage of the national Reclamation Act in 1902. The flood in 

1897 on Red River of the North focused interest on stream gaging 

and floods in Illinois brought resumption of the cooperative program in 1914.

Problems concerning the division of waters along the international boundary led to the formation of the International Joint Comcission in 1912. Starting in 1913, several gaging stations were 

installed on St. Mary River and its tributaries to furnish data for 

the division of waters as stipulated by a treaty between Canada and 

the United States signed in 1909. In later years other international 

stations were established in the Red River of the North and Lake 

of the Woods basins.

As a result of the Rivers and Harbors Act of 1927 and the Flood 

Control Act of 1928, the Corps of Engineers supported a considerable expansion of the work during the period 1928-31 and again in 

1936 after the passage of the Flood Control Act of 1936. These 

programs and the continued support by the Corps of Engineers advanced stream-gaging activities in the area.

Stimulus from irrigation interests played only a minor part in 

augmenting the stream-gaging program in this area. Drainage 

problems in northern Minnesota and other flat areas required 

streamflow records for their solution.

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.
4 COMPILATION OF SURFACE WATER RECORDS, PART 5

DESCRIPTION OF DATA

The gaging-station records are arranged in 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 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 bar chart (see p 1$), 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 qn 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 

toward the mouth, then all stations on the uppermost tributary 

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 stations), 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.

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 drainagearea 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.
DESCRIPTION OF DATA 5

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, baromecric 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 wateryears 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.

Under "Remarks" information is given on factors which effect 

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

in these items is given when 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
COMPILATION OF SURFACE WATER RECORDS. PART 5

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 inches. For streams that are subject to considerable 

regulation, the second table contains adjusted runoff in inches. 

The table of runoff in inches is omitted if the data do not represent 

natural yield without a gross error, whether adjustedor unadjusted.

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 

discharges. 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 lis-ted. 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 nonrecording 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. Momentary maximum 

discharge believed to be representative of the absolute maximum 

for the water year 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 

Jtnown,

Other data listed in this table are the annual mean discharge 

and runoff for both the water year and the calendar year. The annual mean discharge listed for the water year is the same as that 

given in the yearly column in the first table.
DESCRIPTION OF DATA 7

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. Estimates 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 or all 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 records which have been discredited and not 

republished is given with the records published herein. Stations 

for which the entire period of records previously published has 

been discredited are omitted from this report. The following 

is the only station so omitted.

Upper Iowa River near Dorchester, Iowa........................................................... 1938-39

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, one for each of the 14 parts. 

Beginning with the reports of 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, except that the compilation report for part 11 is divided into 2 volumes. The boundaries of the various parts are 

indicated in the following list and on figure 1.

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.

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

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

issued annual or biennial reports that contain records of discharge: Indiana, Missouri, 

Montana, North Dakota, and South Dakota.

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 

hydrologic information and analyses and compilations of data relating to earlier notable floods. The following is a list of these 

reports.

HYDROLOGIC CONDITIONS

Hydrologic conditions in the area covered by this report vary 

greatly with respect to both location and time. Figure 2 shows 

annual discharges for three representative streams, one in the 

Hudson Bay basin and two in the Upper Mississippi River basin. 

The average discharge shown on the graphs is based on the period 

of record at each of the gaging stations.

Of all the basins in the United States, the two covered by this 

report are unusual in that they have a vary large number of lakes 

as the result of glaciation. The natural storage in the lakes, often 

augmented by some additional control with low dams, plays an important role in maintaining the flow of streams principally in Minnesota and Wisconsin.

Except for the high precipitation in the Saskatchewan River basin in Montana, average annual precipitation generally increases 

from north to south and from west to east. Summer storms cause 

floods in most parts of the area, and the spring thaw produces high 

water on many streams.

107. Pembina River at Neche, N. Dak. 

(International gaging station)

Location.--Lat 48°59'20", long 97°33'05" in SE^NW^ sec. 31, T. 164 N., R. 53 W., 2 

blocks east of State Highway 18 at north edge of Neche.

Drainage area.--3.190 sq mi, approximately.

Gage.--Water-stage recorder and concrete control. Altitude of gage is 805 ft (from 

Typographic map). Prior to May 24, 1932, staff gage at Great Northern Railway 

bridge 1 mile upstream at same datum. May 25, 1932, to Apr. 17, 1939, chain gage 

on State Highway 18 bridge 500 ft downstream from railway bridge at same datum.

Average discharge. 42 years (1903-08, 1909-15, 1919-50), 160 cfs.

Extremes.--1903-08. 1909-15, 1919-50: Maximum discharge, 10,700 cfs Apr. 20, 1950 

(gage height, 21.58 ft, backwater from ice), from rating curve extended above 5,300 

cfs; no flow at times during some years.

Remarks. Slight regulation and diversion. At extremely high discharges over bank 

flow upstream from Neche bypasses gage, some returning to Pembina River via Louden 

Coulee and Tongue River and some going to Red River via Plum Creek.

Cooperation. This station is maintained by the United States under agreement with 

Canada.

Drainage area.--9.879 sq mi (revised).

Supplemental records available.--Records of chemical analyses and water temperatures 

for the period October 1944 to September 1945 and of suspended-sediment loads for 

period October 1944 to September 1947 are published in reports of Geological Survey.

Gage.--Water-stage recorder. Datum of gage is 773.84 ft above mean sea level, datum of 

1929, and is at city datum.

Average discharge.--10 years (1940-50), 4,216 cfs.

Extremes. 1940-50: Maximum discharge, 77,000 cfs June 26, 1947 (gage height, 20.8 ft 

in gage well, 21.6 ft from outside floodmark); minimum daily, 80 cfs July 27, 1940, 

Feb. 2-5, 1950.

Maximum stage known since at least 1893, that of June 26, 1947. Flood of May 31, 

1903, reached a stage of 20.9 ft from flood profile by Office of Des Moines City 

Engineer.

Remarks.--Water for municipal supply of Des Moines is taken from infiltration galleries 

on Raccoon River, about 2.5 miles above station. These galleries are 150 to 300 ft 

from the river and generally about 30 ft below grade. At times, water is pumped 

directly from Raccoon River into recharge basins above galleries. Effluent from 

city sewage-treatment plant, which includes stormwater runoff from portion of city, 

enters Des Moines River about 3 miles below station and corresponds roughly to pumpage 

except following heavy local rains. Net effect of pumpage, stormwater, and other 

diversions is not known. Low flow can be regulated by pumpage into or release from 

reservoir of Des Moines Water Works (capacity, 4,£00 acre-ft) on Raccoon River.

606 ILLINOIS RIVER BASIN

545. Chicago Sanitary and Ship Canal at Lockport, 111.

Location. Lat 41°34'11", long 88°04 I 42", in SW£ sec. 27, T. 36 N., R. 10 E., at upper 

end of 9-foot navigation channel in Des Plaines River at Lockport.

Average discharge. 50 years (1900-1950), 6,390 cfs.

Extremes. 1900-1950: Maximum total discharge, 24,567 cfs Mar. 19, 1948; minimum total, 

91 cfs Dec. 15, 1938.

Remarks. Total daily mean discharge includes governmental and private pumpage, inflow 

from Des Plaines River basin, and diversion from Lake Michigan. This total is 

obtained by adding the daily mean discharges, based on half-hourly discharge readings 

at dams, sluice gates, lockages, exciter turbines in operation and main turbines in 

operation as corrected for variable efficiencies, and the leakage of lock gates, dams, 

sluice gates, and turbines not in operation.

Chicago pumpage includes water from Lake Michigan to supply Chicago metropolitan 

area, water from wells within the main-channel drainage area including pumpage to 

municipalities served by Chicago, and an amount varying between 65 and 150 cfs from 

agencies not served by Chicago.

Mean net diversion is obtained by deducting from total discharge the Chicago 

pumpage and inflow from Des Plaines River basin.

The Federal permit of June 26, 1930, issued by the Secretary of War, limits the 

diversion of water from Lake Michigan to an annual average of 1,500 cfs, exclusive 

of pumpage for municipal supplies.

Cooperation. Records furnished by The Metropolitan Sanitary District of Greater Chicago; 

those prior to October 1936, not previously published by Geological Survey.

Location.--Lat 40°39 

downstream from dam 

northeast of Hudson.

582. Money Creek at Lake Bloomington, 111.

'47", long 88°56'23", in NW^ sec. 1, T. 25 N., R. 2 E., 1,300 ft

am at Lake Bloomington, 2.1 miles upstream from mouth, and 4 mile

Drainage area.--6 sq mi (revised).

Gage.--Water-stage recorder and artificial control. Datum of gage is 678.05 ft above 

mean sea level. Prior to Oct. 1, 1940, water-stage recorder in pumping plant just 

upstream from dam at datum 700.00 ft above mean sea level. Recorder at former site 

now used as auxiliary gage to give stage of lake.

Average discharge. 20 years (1930-50) 40.8 cfs or 9,619.3 million gallons per year 

(adjusted for storage and diversion).

Remarks.--Flow regulated by Lake Bloomington (area of lake at level of crest of spillway, 531 acres). Water is diverted from lake by pumping for municipal supply of 

Bloomington. Discharge past gage is made up of discharge through spillway, seepage 

through dam, runoff from area below dam (0.4 sq mi), and return flow from water 

diverted from lake for use at pumping plant and not otherwise measured. The last 

three items were not included in records prior to Oct. 1, 1940. Records adjusted for 

storage and pumpage, but not for evaporation and seepage.
