SURFACE WATER SUPPLY OF HUDSON BAY AND UPPER MISSISSIPPI RIVER BASIN, 1950

SCOPE OF WORK

This volume is one of a series of 14 reports presenting results of measurements of 

stage and flow made on streams, lakes, and reservoirs in the United States during the 

water year ending September 30, 1950. The work was begun In 1888 In connection with 

special studies relating to Irrigation. Measurements of the flow of streams and of the 

stage and contents of lakes and reservoirs have been made at about 12,060 gaging stations 

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

30, 1950, 6,540 gaging stations, including those In Hawaii and Alaska were being maintained by the Geological Survey and cooperating organizations. Miscellaneous discharge 

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

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

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

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

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

DEFINITION OF TERMS

The units in which stream-flow data are presented in this report and other terms used 

herein are defined as follows:

"Second-feet" is an abbreviation for "cubic feet per second." A second-foot Is the 

rate of discharge of a stream whose channel is 1 square foot in cross-sectional area and 

whose average velocity is. 1 foot per second.

"Second-feet per square mile" is the average number of cubic feet of water flowing per 

second from each square mile of area, drained, on the assumption that ths runoff is distributed uniformly both as regards time and area.

"Runoff in inches" is the depth to which an area would be covered if all the water 

draining from it in a given period were uniformly distributed on its surface. It is used 

for comparing runoff with rainfall, which is usually expressed In inches.

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

1 foot ar"i is equivalent to 43,560 cubic feet. The term Is commonly used in connection 

with storage for Irrigation.

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

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

represents a runoff of 0.0372 inch from 1 square mile.

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

and discharge."

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

a reach of the channel, or an artificial structure.

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

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

1
2 SURFACE WATER SUPPLY, 1950, PART b

"Drainage area" of a stream at a specified location is that area, measured in a horizontal plane, which is enclosed by a topographic divide such that direct surface runoff from 

precipitation normally would drain by gravity into the river basin above the specified 

point. Figures of drainage area given herein include all closed basins or non-contributing 

areas within the area unless otherwise noted.

EXPLANATION OF DATA

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

of discharge, and general information used to supplement the records of stage and discharge 

measurements in determining the daily flow. The records of stage are obtained either from 

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

stations at which the stage-discharge relation \a affected by ice, the days included in 

the periods of ice effect either are indicated in the table by symbols referring to a 

footnote that states this fact or are given in a general note following the table. The 

days on which discharge measurements were made during or between periods of ice effect, 

shortly before the first period, or shortly after the last period are similarly indicated 

by a footnote.

For most of the gaging stations on streams in the area covered by this report the data 

presented comprise a description of the station, a table showing the daily discharge of

the stream, and a table of monthly and yearly discharge and runoff. Skeleton rating 

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

greater part of the year was determined by the shifting-control method, the slope method, 

or other special methods.

The description of the station gives the type of gage, location, drainage area, records 

available, average discharge, extremes of discharge-, general remarks, and notations of revisions of previously published record. The location of the gag-ing station and the drainage area are obtained from the most accurate maps available. Under "Average discharge" is 

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

tions having less than 10 complete years of record or for stations where changes in water 

development during the period of record cause the figure to have little significance. 

Under "Extremes" are given the maximum discharge and gage height; the minimum discharge if 

there is little or no 'regulation; the minimum daily discharge if there is extensive regulation (also the minimum discharge if useful); and the minimum gage height (unless it is 

of no importance). Unless otherwise qualified, the maximum discharge corresponds to the 

crest stage, obtained by use of a water-stage recorder, a crest-stage indicator, or a nonrecording gage read at the time of the crest. Information pertaining to the accuracy of 

the records and conditions which affect the natural flow at the gaging station is given 

under "Remarks."

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

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

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

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

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

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

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

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

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

1933. If there were no daily, monthly, or annual figures of discharge involved in the 

revision, that fact is brought out by notations after the year dates as follows: (M) means 

that only the instantaneous maximum.discharge was revised; (m) that only the instantaneous 

minimum was revised; and (P) that only peak discharges were revised. If the drainage area 

has been revised, the report in which the revised figure was first published is given. It 

should be noted that for all stations for which second-feet per square mile and runoff in 

inches are published, a revision of the drainage area necessitates corresponding revision 

of all figures based on the drainage area. Revised figures of second-feet per square mile 

and runoff in inches resulting from a revision of the drainage area only are usually not 

published in the annual series of reports.

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

sudden or rapid fluctuation, the table gives the discharge corresponding to the.daily mean 

gage height. For stations subject to such fluctuation the daily mean gage height may not 

indicate the true daily mean discharge, which must be obtained by averaging the discharge 

for parts of the day or by using the discharge integrator, an instrument for obtaining the 

daily mean discharge from a continuous gage-height graph and containing as an essential 

element a curve representing the stage-discharge relation at the station. For stations 

equipped with nonrecording gages, the table of daily discharge gives the discharge
ACCURACY OF FIELD DATA AND COMPUTED RESULTS 5

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

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

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

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

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

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

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

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

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

feet per second during the month.

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

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

base discharge, which is given in parentheses, is 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.

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

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

but is omitted from succeeding reports.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

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

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

records.

The station description gives a statement in regard to the general accuracy of the rec-» 

ords. "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 accurate than the daily records.

Yield at some stations as indicated by monthly means may vary widely from natural yield, 

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

due to artificial causes, or other factors. For such stations figures of "second-feet per 

square mile" and "runoff in inches" are not published unless storage or diversion records 

are included Indicating the extent of the regulation or diversion or unless satisfactory 

adjustments can be made for changes in contents or reservoirs or for other changes incident 

to use and control. Evaporation from a reservoir is not included in the adjustments for 

changes in reaervoir contents, unless its inclusion is indicated. Even at those stations 

where adjustments are made, in so^-ne instances large errors in computed yields may occur 

when relatively large negative adjustments are applied or when evaporation is large in 

comparison with the observed discharge. Figures of second-feet per square mile and runoff 

in inches are also omitted if the drainage area includes large noneontribufcing areas or if 

the average annual rainfall over the drainage area is less than 20 inches.
6 SURFACE WATER SUPPLY, 1950, PART 5

Many gaging stations on streams in the irrigated areas of the United States are situated 

above most of the diversions from those streams, and therefore the discharge recorded does 

not show the water supply available for further development, as prior appropriations below 

the station must first be satisfied.

The table of monthly discharge presents in summary the distribution of the flow past the 

station. The table of daily discharge affords opportunity for more detailed studies of the 

variation in flow. As further observations in each succeeding year may be expected to 

throw new light on data previously published, it should be borne in mind that such data are 

subject to revision in succeeding water-supply papers.

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

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

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

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

relative order as the streams and gaging stations in the body of the report. An index of 

the records obtained prior to 1904 has been published in Water-Supply Paper 119.

Each of the reports on surface water supply for the year 1939, issued as Water-supply 

Papers 871 to 884 (see table on p. 8), contains, for the area covered by that report, a 

summary of yearly discharge at gaging stations at which 10 or more complete years of record 

have been collected. These summaries are available also as separate reprints.

Reports have been published that are compilations of records for various areas, usually 

a single State or drainage basin. These reports contain records previously published 

(some of which have been revised), as well as some records not contained in the annual 

series of water-supply papers. The following table gives the numbers and titles of these 

reports, arranged alphabetically, some by States and some by drainage basins.

Note.--The Soil Conservation Service of the United States Department of Agriculture has collected 

records of runoff from five areas In Wisconsin, four in Illinois, and one in Iowa. One area in 

Wisconsin, comprising less than 5 acres, Is near La Crosse (records begin in 1932), and the other 

four, comprising less than 330 acres each, are near Fennimore (records begin in 1938). The four 

areas In Illinois, comprising less than 300 acres each, are near Edwardsville (records begin in 

1938). The area in Iowa, comprising 3.5 square miles, is near Iowa City (records begin in 1925). 

These records are in the files of the Soil Conservation Service.

COOPERATION

The work in the several States was done under cooperative agreements with the organizations listed below:

Illinois: State Department of Registration and Education, N. J. Puffer,

geologist; and State Highway Department, C. W. Brown, chief engineer.

North Dakota: State Water Conservation Commission, J. J. Walsh, chief engineer.

Wisconsin: Public Service Commission of Wisconsin, G. P. Steinmetz, chief 

engineer; and Wisconsin Committee on Water Pollution, Edward Schneberger, 

chairman.

Financial assistance was furnished by the Corps of Engineers in the operation of 

223 gaging stations, of which 70 were In Illinois, 13 in Indiana, 38 in Iowa, 50 in 

Minnesota, 12 in Missouri, 12 in North Dakota, 2 in South Dakota, and 26 in Wisconsin.

Financial assistance was also furnished by The Fish and Wildlife Service of the 

United States Department of the Interior in the operation of certain stations in 

Wisconsin.

Several gaging stations in the Hudson Bay Basin were maintained from funds appropriated by the United States Department of State.

Full cooperation exists between this organization and the Water Resources Division, 

Department of Resources and Development, Canada. On waters adjacent to the International 

boundary, certain stations are maintained Jointly by the United States and Canada under 

the terms of the Boundary Waters Treaty of 1909, and others are maintained under a subsequent agreement between the two Governments. The records from all these stations are 

obtained in such a manner as to be equally acceptable and available in both countries. 

These stations are herein designated international gaging stations.

Assistance in collecting records was also rendered by the following organizations:

Illinois: North Counties Hydroelectric Co., city of Bloomington, and East 

Side Levee and Sanitary District.

Iowa: Union Electric Power Co., Iowa tieetric Co., Iowa Electric Light & Power 

Co., Des Moines Waterworks, Jacob E. Decker & Sons, State University of Iowa, and 

the cities of Ames, Cedar Rapids, Des Moines, Port Dodge, Iowa City, Marshalltown, 

Ottumwa, and Waterloo.

Wisconsin: Northern States Power Co., Wisconsin Public Service Corporation, 

and Wisconsin Valley Improvement Co.

DIVISION OP WORK

The stream-gaging work was conducted by the water resources division of the Geological 

Survey, Carl G. Paulsen, chief hydraulic engineer, and J. V. B. Wells, chief of the 

surface water branch.

The data for the stations in the several States were collected and prepared for publication under the supervision of district engineers as follows: In Illinois (except for 

Mississippi River at Alton and East Pork Galena at Council Hill), J. H. Morgan; in 

Indiana, D. M. Corbett; in Iowa and for Turtle Creek near Austin, Minn,, V. R. Bennion; 

in Minnesota (except for St. Croix River near Rush City, Red River of the North at 

Halstad and at Oslo and Turtle Creek near Austin), in South Dakota, and for Mississippi 

River at Prescott and at La Crosse, Wis., P. R. Speer; in Missouri and for Mississippi 

River at Alton, 111., H. C. Bolon; in Montana, A. H. Tuttle until December 31, 1949, 

succeeded by Frank Suermitz on January 3, 1950; in North Dakota and for Red River of the

channel of Milk River through Canada and back into Montana where it is used for irrigation in Milk River Valley east of Havre. Some water may be returned to St. Mary River 

at Kennedy Creek and St. Mary crossings.

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

united states and Canada under the Boundary Waters Treaty. The records have been 

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

Resources and Development, Canada.

142 MISSISSIPPI RIVER MAIN STEM

Mississippi River at St. Paul, Minn.

Location.--Water-stage recorder, lat. 44°56'40", long. 93°05'20", in NE£ sec. 6, T. 28 N., 

K. 2a W., in St. Paul, 6 miles downstream from Minnesota River. Datum of gage is 

684.16 feet above mean sea level, adjustment of 1912. Auxiliary water-stage recorder 

in SE£ sec. 22, T. 28 N., R. 22 W., in South St. Paul, 7 miles downstream, at same 

datum.

Drainage area.--36,800 square miles.

Kecoras available. March 1887 to September 1950.

Average aiscnarge'.--58 years (1892-1950), 9,424 second-feet (adjusted for diversion).

Kxcremes.--maximum discharge during year, 53,900 second-feet May 13 (gage height, 12.95 

reet); minimum daily discharge, 2,810 second-feet Dec. 9.

1887-1950: Maximum discharge, 80,800 second-feet Apr. 6, 1897 (gage height, 18.0 

feet); minimum daily, 632 second-feet Aug. 26, 1934.

Maximum discharge known, 107,000 second-feet Apr. 29, 1881 (gage height, 19.7 feet), 

determined by Corps of Engineers.

Remarks.--Records good. Flow partly regulated by Government reservoirs on headwaters and 

oy power plants. Backwater from Hastings Dam most of year; discharge computed using 

fall as a factor. Beginning July 20, 1938, sewage from Minneapolis and St. Paul, which 

formerly entered above station, was diverted to a sewage-disposal plant, thence to 

river below station. Figures of daily discharge do not include this diversion.

Cooperation. Records of Mississippi River at Twin City Lock and Dam computed and furnisnea by Ford Motor Co. Gage readings at South St. Paul and on outside staff gage at 

St. Paul furnished by Corps of Engineers.

Revisions (water years).--W 875: 1938. W 895: 1939.

Records available.--October 1932 to September 1950 in reports of Geological Survey. January IBYB to December 1932 in report of Iowa State Planning Board entitled "Stream Flow 

Records of Iowa, 1873-1932." Records for period May 1913, when Keokuk Dam was completed 

to September 1937 adjusted for change in contents in Keokuk Reservoir, those after 

September 1937 unadjusted. Records prior to 1913 collected at site at Galland, 8 miles 

upstream.

Average discharge.--72 years (1878-1950), 61,150 second-feet.

Extremes.--Maximum daily discharge during year, 175,900 second-feet Apr. 25, 26; minimum 

daily, 12,800 second-feet Oct. 2.

1878-1950: Maximum discharge, 314,000 second-feet May 16, 1888 (gage height, 19.6 

feet); minimum daily, 5,000 second-feet Dec. 27, 1933.

Flood of June 6, 1851, reached a stage of 21.0 feet; estimated at 13.5 feet at 

Galland (discharge, 360,000 second-feet).

Remarks. Records good. Discharge computed from records of operation of turbines in power 

plant and spillway gates in dam. Flow regulated by reservoirs and navigation dams.

Cooperation. Records of daily discharge furnished by Union Electric Power Co. Two discharge measurements made by Geological Survey. One discharge measurement furnished by 

Corps of Engineers.

RESERVOIRS IN CHIPPEWA RIVER BASIN 209

Nine reservoirs are used to stabilize flow of Chippewa, Flambeau, and Red Cedar Rivers. 

Moose Lake, Chippewa Reservoir, Rest Lake and Flambeau Reservoir are owned and operated 

by the Chippewa-Flambeau Improvement Co. Wissota, Birch, Cedar, Long, and Bear Lakes 

are operated by'the Northern States Power Co., Eau Claire, Wis. The Northern States Power 

Co. furnishes gage heights and contents for all the above reservoirs. The relation of 

these reservoirs to the gaging stations on Chippewa, Flambeau, and Red Cedar Rivers is as 

follows (figures in parentheses following name of reservoir show usable capacity in winter 

in millions of cubic feet): Moose Lake (400) and Chippewa Reservoir (9,650) are on 

Chippewa River upstream from station at Bishops Bridge; Rest Lake (660) and Flambeau Reservoir (5,900) are on Flambeau River and tributary which enter upstream from the station 

on Flambeau River at Flambeau Reservoir; Lake Wissota (3,547) is on Chippewa River upstream from station at Chippewa Falls; Birch Lake (908), Cedar Lake (577), Long Lake (637), 

and Bear Lake (413) are on Red Cedar River or its.tributaries which enter upstream from 

station on Red Cedar River near Colfax and Chippewa River at Durand. The usable capacity 

of these reservoirs is usually less in summer than in winter because the allowable summer 

draw-down is limited in the interest of riparian property owners. There are from time to 

time formal or informal changes in capacity and in minimum draw-down levels. For detailed 

location of these reservoirs see Water-Supply Paper 955, page 179.

RESERVOIRS IN THE WISCONSIN RIVER BASIN

Twenty-one reservoirs are used to stabilize flow of the Wisconsin and Tomahawk Rivers. 

The reservoirs are owned and operated by Wisconsin Valley Improvement Co., who furnished 

the gage heights and contents for the individual reservoirs. The relation of these reservoirs to gaging stations on the Wisconsin River is as follows (figures in parenthesis 

following name of reservoir show usable capacity, in winter, in millions of cubic feet): 

The first 13, Lac Vieux Desert (595), Twin Lakes (302). Buckatabon Lakes (142), Long 

Lake (384), Little Deerskin (22), Seven Mile Lake (117), Lower Nine Mile Lake (93), Burnt 

Rollways (596), Sugar Camp (335), Little St. Germain Lake (142), Big St. Germain Lake 

(24.3), Pickerel Lake (250), and Rainbow Reservoir (2,020) are on the Wisconsin River or 

on tributaries that enter upstream from station at Rainbow Reservoir near Lake Tomahawk; 

North Pelican (205), and South Pelican (305) are on tributaries that enter upstream from 

station at Whirlpool Rapids near Rhlnelander; Minocqua (651), Squirrel Lake (152), 

Willow Reservoir (3,350), Rice Reservoir (1,788) and Spirit Reservoir (775) are on tributaries that enter upstream from station at Merrill; Big Eau Pleine Reservoir (4,551) is 

on a tributary that enters upstream from station at Nekoosa. Minocqua, Squirrel Lake, 

Willow Reservoir, and Rice Reservoir also regulate flow of Tomahawk River upstream from 

station at Tomahawk. The usable capacity of these reservoirs is usually less in summer 

than in winter because the allowable summer draw-down is limited in the interests of 

riparian property owners. There are from time to time formal or informal changes in 

capacity and in minimum draw-down levels. For detailed location of these reservoirs see 

Water-Supply Paper 955, page 210.

Remarks. Records fair. Gage read twice daily or oftener and record kept of hours of

operation of single-unit power plant. Water diverted periodically from Wisconsin River 

into Cranberry Creek Basin for Cranberry culture. Probably most of water diverted was 

lost by evaporation, transpiration, and ground-water seepage. These diversions were as 

follows:

ROCK RIVER BASIN 289

Rock River at Como, 111.

Location.--Water-stage recorder, lat. 41°47'00", long. B9°44'58", in NE^ sec. 25, T. 21 

N., K. 6 E., 1 mile upstream from Como, 3 miles downstream from Rock Palls, and 3^ 

miles upstream from Elkhorn Creek. Datum of gage is 606.83 feet above mean sea level, 

datum of 1929.

Drainage area.--8,700 square miles.

Kecoras available.--December 1933 to September 1950. November 1914 to September 1934 at 

Lyndon, itjf- miles downstream.

Average discharge.--36 years (1914-50), 5,147 second-feet (discharge for site at Lyndon 

adjusted for difference In drainage area).

Extremes.--Maximum discharge during year, about 25,000 second-feet Mar. 7; minimum daily,

 9144 second-feet Oct. 18.

1914-50: Maximum discharge, 51,000 second-feet Feb. 22, 1937, at lower dam at Rock 

Palls, from rating curve extended above 21,000 second-feet by logarithmic plotting; 

minimum daily, 440 second-feet Aug. 20, 1934.

Remarks. Records good except those for periods of Ice effect or doubtful or no gageneight record, which are fair. About 100 second-feet diverted above gage to Illinois 

and Mississippi Canal. Some diurnal fluctuation caused by power plants above station.

Cooperation.--Two discharge measurements furnished by Corps of Engineers.

 1'eet); minimum, 14 second-feet Feb. 24 (gage height, 2.71 feet).

1942-50: Maximum discharge, 5,770 second-feet Jan. 6, 1946 (gage height, 16.04 

feet); minimum, 8.6 second-feet Dec. 17, 1948 (gage height, 2.62 feet), result of ice 

jam above gage.

Maximum stage known, 17.7 feet in June 1937, from information by local residents. 

Revisions.--The maximum discharge for the discontinued gaging station Rock Creek at 

Morrison for the period March to September 1940, has been revised to 1,200 second-feet. 

Aug. 13, 1940 (gage height, 12.58 feet), superseding figure published in Water-Supply 

Paper 895. 

Remarks.--Records good except those for Oct. 1 to Dec. 13, which are fair, and those

for periods of ice effect or no gage-height record, which are poor.

Mote.--Stage-discharge relation affected by ice Jan. 8-17, Mar. 12-25.
DES MOINES RIVER BASIN 363

Des Moines River below Raccoon River, at Des Moines, Iowa

Location. Water-stage recorder just upstream from Scott Street Dam, lat. 41°34"53", long.

 93°3t>'45", in NW£ sec. 10, T. 78 N., R. 24 W., at Scott Street Bridge in Des Moines, 

100 feet downstream from Raccoon River, 1 mile downstream from dam of Iowa Power & 

Light Co., and 2j miles downstream from dam of Des Moines Water Works on Raccoon River. 

Datum of gage is 773.84 feet above mean sea level, datum of 1929, "and at city datum.

Drainage area. 9,770 square miles.

Kecords available. April 1940 to September 1950.

Average discharge. 10 years (1941-50), 4,216 second-feet.

Extremes.--Maximum discharge during year, 24,800 second-feet June 21 (gage height, 11.56 

feet); minimum daily, 80 second-feet Feb. 2-5; minimum gage height, 4.00 feet Jan. 28.

1940-50: Maximum discharge, 77,000 second-feet June 26, 1947 "(gage height, 20.8 

feet in gage well, 21,6 feet from outside floodmark); minimum daily, 80 second-feet 

July 27, 1940, Feb. 2-5, 1950; minimum gage height, 3.39 feet Feb. 1, 11, 1948.

Maximum stage known, 21.6 feet, outside floodmark, June 26, 1947. River reached 

stage of about 20.9 feet, present site and datum, May 31, 1903, from flood profile by 

Office of City Engineer.

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

 municipal supply of Des Moines is taken from infiltration galleries on Raccoon River, 

about 2j miles above station. These are 150 to 300 feet from river and generally about 

30 feet below grade. At times water is pumped directly from Raccoon River into recharge 

basins above galleries. Effluent from city sewage treatment plant, which includes 

storm-water 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, storm water, and other diversions is not known. Low flow can be 

regulated by pumpage into or release from reservoir of Des Moines Water Works (capacity, 4,800 acre-feet) on Raccoon River.

Cooperation.--Average monthly pumpage from galleries, in second-feet, computed from records furnished by Des Moines Water Works; water-stage recorder inspected by employee 

of that agency.

Discharge, in second-feet, water year October 1949 to September 1950

entitled "Stream Plow Records of Iowa, 1873-1932." 

Average discharge. 33 years, 4,578 second-feet. 

Extremes. Maximum discharge during year, 34,600 second-feet May 11 (gage height, 11.68

reet); minimum, 84 second-feet Feb. 5 (gage height, -0.24 foot).

1917-50: Maximum discharge observed, 135,000 second-feet June 7, 1947 (gage height,

20.2 feet); minimum daily, 30 second-feet Jan. 27-29, 31, Feb. 2, 3, 5-7, 1940. 

Remarks. Records good except those for periods computed from graph based on wire-weight

gage readings or partly estimated gage readings or those for periods of ice effect,

which are fair. Diurnal fluctuation at low flow caused by power plant above station. 

Cooperation. Station operated under provisions of Federal Power Commission project No. 925

(city or Ottumwa). Gage-height record collected in cooperation with U. S. Weather

Bureau.

Chicago Sanitary and Ship Canal at Lockport, 111.

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

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

Records available. October 1936 to September 1950 in reports of Geological Survey. Janu-

 ary 1UUU to September 1946 in 1937 State report entitled "Stream-flow data of Illinois.

Average discharge. 50 years, 6,390 second-feet.

Extremes. Maximum total discharge during year, 12,689 second-feet Apr. 25; minimum total,

 y ,1V3 second-feet Nov. 7.

1900-1950: Maximum total discharge, 20,613 second-feet Apr. 5, 1947; minimnr total, 

91 second-feet Dec. 15, 1938. 

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

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

by adding the mean daily 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 C ;o metropolitan 

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

municipalities served by Chicago, and an average of about 13V second-feet 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 second-feet, exclusive of pumpage for municipal supplies.

Cooperation. Records furnished by Sanitary District of Chicago.

and 6 miles upstream from Fox chain of lakes.

Drainage area. 880 square miles.

Records available.--October 1939 to September 1950.

Average discharge.--11 years, 412 second-feet.

Extremes.--Maximum discharge observed during year, 2,400 second-feet Mar. 29 (gage height, 

6.98 feet); minimum observed, 71 second-feet Dec. 2 (gage height, 4.66 feet).

1939-50:. Maximum discharge observed, 5,400 second-feet Mar. 17, 1943 (gage height, 

8.60 feet); no flow Oct. 26, 1945; minimum daily discharge, 50 second-feet Nov. 1, 

1944.

Remarks.--Records fair. Control is a broad-crested concrete dam on which little ice 

forms during winter. Three lift gates, each six feet wide, were in operation during 

the year; discharge through gates was computed by weir formula and added to flow over 

dam. Gage read twice daily.

Remarks. Plow regulated by Lake Bloomington (area of lake at level of crest of spillway, 

 b31 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 square mile), 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.

Big Muddy River at Murphysboro, 111.

Location. Water-stage recorder, lat. 37°44'55", long. 89°20'45", in SEij sec. 8, T. 93., 

K. a W., at Illinois Central Railroad bridge across mouth of Lewis Creek at Murphysboro. Auxiliary wire-weight gage at bridge on State Highway 13, 7,700 feet upstream. 

Datum of each gage is 335.5 feet above mean sea level, datum of 1929.

Drainage area. 2,170 square miles.

Records available. December 1916 to September 1950 (fragmentary prior to 1931).

Average discharge. 20 years (1930-50), 1,933 second-feet.

Extremes. Maximum discharge during year, 27,000 second-feet Jan. 15; maximum gage height, 

3b.4E> feet Jan. 16; maximum daily reverse flow, 304 second-feet July 21, caused by 

backwater from Mississippi River; minimum daily discharge unaffected by backwater, 53 

second-feet Oct. 3.

1917-50: Maximum discharge, 28,000 second-feet Jan. 28, 1949 (gage height, 36.01 

feet); maximum daily reverse flow, 4,400 second-feet July 3, 1947, caused by backwater 

from Mississippi River; no flow Aug. 13 to Sept. 1, 1936 (unaffected by backwater).

Flood of Feb. 2 1916, reached a stage of 34.9 feet, present datum (discharge, 

28,000 second-feet).

Remarks. Records good above 5,000 second-feet and fair below except those for periods of 

no gage-height record, which are poor. Discharge computed by using fall as determined 

by twice-daily readings of auxiliary gage as a factor.

Discharge, in second-feet, water year October 1949 to September 195O

as well as graphs showing the fl uctuation in elevation. Discharge measurements, made at

the outflow, are also available in some instances.

The lakes for which records have been collected are listed in the following table. The 

established level, sometimes referred to as the legal level, is that elevation set by the 

courts to which the average level of the lake is to be held; it is normally set at about 

the average level that has prevailed for a number of years prior to the establishment of 

the level.
