SURFACE WATER SUPPLY OP HUDSON BAY AND UPPER MISSISSIPPI RIVER BASINS, 1949

SCOPE OP 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, 1949. 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 11,680 gaging stations 

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

30, 1949, 6,240 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 the 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 distriouted 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 c.- acre to the depth of 

1 foot and is equivalent to 43,560 cubic feet. The term is commonly used in connectionwith 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.

2 SURFACE WATER SUPPLY, 1949, PART 5

"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.

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 florf. The records of stage are obtained either from 

direct readings on a nonrecording gage or from a water-stage recorder that gives a continuaus 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 msan 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 i,s 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 dally 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 gaging 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 stations 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 dally 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 or a nonrecordlng 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 selecteu 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 OP 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 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 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 reservoir contents, unless its inclusion is indicated. Even at those stations 

where adjustments are made, in some 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 noncontributing areas or 'if 

the average annual rainfall over the drainage area is less than 20 inches 

949152 O - 51 - 2
C SURFACE WATER SUPPLY, 194'J, 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.

PUBLICATIONS

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 ths year 1939, issued as Water-Supply 

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

suircnary 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.

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

219 gaging stations, of which 69 were in Illinois, 13 in Indiana, 40 in Iowa, 46 in 

Minnesota, 12 in Missouri, 9 in North Dakota, 2 in South Dakota, and P9 in Wisconsin. 

Financial assistance was also furnished by The Pish 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.

Pull 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 fallowing organizations:

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

Side Levee and Sanitary District.

Iowa: Union Electric Power Co., Interstate Power Co., Iowa Electric Co., 

Iowa Electric Light & Power Co., Des Moines Waterworks, Jacob E. Decker & Sons, 

Boone Water Department, Iowa State College, State-University of Iowa, and the 

cities of Ames, Cedar Rapids, Des Moines, Iowa City, Marshalltown, Mason City, 

Ottumwa, and Waterloo.

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

and Wisconsin Valley Improvement Co.

DIVISION OF 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, cnief 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), J. H. Morgan; in Indiana, D. M. Corbett; in Iowa and for 

Turtle Creek near Austin, Minn., L. C. Crawford until Sept. 5, 1949, succeeded on September 6, 1949, by 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 Prescptt and at La Crosse, Wis., P. R. Speer; in 

Missouri and for Mississippi River at Alton, III.. H. C. Bolon; in Montana, A. H. Tuttle; 

in North Dakota and for Red River of the North at Halstad and at Oslo, Minn., R. E. Marsh 

until January 23, 1949, succeeded on January 24, 1S4S, by H. M. Erskine; in Wisconsin 

(except for Mississippi River at Prescott and La Crosse), and for St. Croix River near 

Rush City, Minn., F. C. Christopherson.

The records were reviewed and the manuscript prepared for publication under the direction of B. J. Peterson, chief, annual reports section.

MISSISSIPPI RIVER MAIN STEM 139

Mississippi River at St. Paul, Minn.

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

N77TT 22 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 oEv sec. 22, T. 28 N., R. 22 W., in South St. Paul, 7 miles downstream, at same datum.

Drainage area.- 36,800 square miles.

Records available.- March 1887 to September 1949

Average discharge.- 57 years (1892-1949), 9,368 second-feet (adjusted for diversion)

hxtremeV- Maximum discharge during year, 43,200 second-feet Apr. 8 (gage height 11 30 

Feet); minimum daily discharge, 2,220 second-feet Jan. 11.

1887-1949: Maximum discharge, 80,800 second-feet Apr. 6, 1897 (gage height 18 0 

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

'laxXL- 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 

by 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 furnisned by Ford Motor Co. Gage readings at South St. Paul and on outside staff gage 

at ot. Paul furnished by Corps of Engineers.

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

Heeords available.- Discharge: March 1933 to January 1938 and October 1939 to September 

iy4t) in reports of Geological Survey. In reports of Mississippi River Commission as 

follows: 1880-1927, results of discharge measurements made intermittently; 1928-32, 

daily discharge, at Grafton, 15 miles upstream; and 1933 to 1944, daily discharge at 

Alton.

Gage heights: Since January 1904 In reports of Mississippi River Commission. December 1890 to September 1893 and 1917-40 in reports of U. S. Weather Bureau.

Average discharge.- 14 years (1933-37, 1939-49), 94,120 second-feet.

Extremes - Maximum discharge during year, 219,000 second-feet Mar. 13; maximum gage height, 

4lb.UH feet Mar. 12; minimum discharge, 7,960 second-feet Nov. 7; minimum gage height, 

394.02 feet Dec. 23.

429.91 feet); minimum, that of Nov. 7, 1948; minimum gage height, 390.8 feet Jan. 15, 

1940.

Maximum stage known, 432.42 feet, present datum, In June 1844.

Remarks.- Records excellent. Fifty-one discharge measurements made during year. Stage-

"* discharge relation affected by backwater from Missouri River. Pall between reference 

and auxiliary gages use'd as a factor in computing discharge. Plow partly regulated by 

many reservoirs and navigation dams on upper Mississippi River, and by diversion through 

Chicago Sanitary and Ship Canal from Lake Michigan into Illinois River.

Cooperation.- Alton gage-height record furnished by Corps of Engineers.

RESERVOIRS IN CHIPPEWA RIVER BASIN 207

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 Bishop's 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 (3,54V) 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 Fed Cedar River or its tributaries which enter upstream 

from station on Red Cedar River near Co Ifax 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.

248 RESERVOIRS IN WISCONSIN RIVER BASIN

Twenty-one reservoirs are used to stabilize flow of 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 Lake (93), Burnt Rollways 

(596), Sugar Camp (335), Little St. Germain Lake (142), Big St. Germain Lake (243), 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 Rhinelander; 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 cummer than in winter because

278 ROCK RIVER BASIN

Rock River at Rockton, 111.

Location.- Water-stage recorder, lat. 42°27'05", long. 89°04'20", in SE-J-NW^ sec. 24, T.

4b U., R. 12 E., at highway bridge in Rockton, three-quarters of a mile downstream

from Pecatonica River. Datum of gage is 707.94 feet above mean sea level, datum of

1929 (levels by Corps of Engineers). 

Drainage area.- 6,290 square miles.

Kecords available.- June 1903 to March 1909, March 1940 to September 1949. 

Extremes.- Maximum discharge during year, 16,500 second-feet Mar. 9 (gage height, 10.57

reet}; minimum daily, 668 second-feet Sept. 25.

1903-9, 1940-49: Maximum discharge observed, 28,500 second-feet Mar. 22, 1904

(gage height, 13.8 feet, datum then in use); minimum daily, 650 second-feet Sept. 2,

1946.

Flood of February 1937 reached a stage of 14.6 feet (backwater from ice), from

painted floodmark. Flood of March 1904 probably reached a somewhat lower stage. 

Remarks.- Records good except those for periods-of ice effect or when gage readings are

not representative of average for day, which are poor. Low flow regulated by power

plants above station.

Cooperation.- One discharge measurement furnished by Corps of Engineers. 

Hevlslons [water years).- W 325: 1904-9. W 895: 1904(M).

Records available.- October 1924 to September 1927, October 1933 to September 1949. 

April 192U to September 1924 at site 1.3 miles upstream.

Average discharge.- 23 years (1920-27, 1933-49), 1,626 second-feet.

Extremes.- Maximum discharge during year, 14,500 second-feet Mar. 7 (gage height, 9.54 

reet); minimum observed, 87 second-feet Oct. 7-9 (gage height, 0.22 foot).

1920-27. 1933-49: Maximum discharge, 37,100 second-feet June 24, 1947 (gage height, 

19.85 feet); no flow for a short time on Jan. 9, 25, 1938, caused by manipulation of 

gates in control dam; minimum daily, 17 second-feet Jan. 28, 1940 (unaffected by gate 

operation).

A stage of 17.03 feet was observed at present site Apr. 2, 1933 (control dam 

destroyed). A stage of about 20.5 feet, from floodmarks, occurred June 6, 1918, at 

site 1.3 miles upstream (discharge, 32,000 second-feet, from rating curve extended 

above 17,000 second-feet). A stage of 23.6 feet occurred in 1903 at U. S. Weather 

Bureau gage on Chicago & Northwestern Railroad bridge, 2.5 miles downstream (discharge, 

32,000 second-feet, from rating curve extended above 28,000 second-feet).

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

M., K. 24 W., at Second Avenue Bridge in Des Moines, 2.8 miles upstream from Raccoon 

River and 4^ miles downstream from Beaver Creek. Control is concrete multiple-arch 

dam of Iowa Power & Light Co., 1.8 miles downstream. Datum of gage is 773.84 feet 

above mean sea level, datum of 1929, and at city datum.

Drainage area.- 6,180 square miles.

Records available.- October 1902 to August 1903 (gage heights only), May 1905 to July 

1906, October 1914 to February 1915 (gage heights only), March 1915 to September 1927, 

and October 1932 to September 1949 in reports of Geological Survey. 1893, 1894, 1897- 

1927 in report of Iowa State Planning Board entitled "Stream Plow Records of Iowa, 

1873-1932."

Average discharge.- 29 years (1915-27, 1932-49), 2,092 second-feet.

Extremes.- Maximum discharge during year, 15,300 second-feet Mar. 8 (gage height, 19.43 

rest); minimum, 89 second-feet Oct. 23, 26, 27, Sept. 28 (gage height, 12.43 feet).

1915-27, 1932-49: Maximum discharge, 39,500 second-feet June 26, 1947 (gage height, 

26.5 feet), but may have been greater June 7, 1918; maximum gage height, 16.5 feet 

June 7, 1918, site and datum then in use; minimum unregulated discharge, 24 secondfeet Jan, 29, 30, 1940; operation of sluice gates in control dam at times has caused 

brief periods of no flow.

Maximum stage known, about 27.3 feet May 31, 1903, present site and datum, from 

flood profile by Office of City Engineer (probably backwater from Raccoon River).

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

suspended sediment, loads for the water jear 1949 are given in Water-Supply Paper 1162.

DES MOINES RIYER BASIN 353

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.-

 938 3K'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 2| 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.

Hecords available.- April 1940 to September 1949.

Extremes.- Maximum discharge during year, 28,100 second-feet Mar. 7 (gage height, 12.58 

feet); minimum, 148 second-feet Oct. 23; minimum gage height, 3.99 feet Oct. 4.

1940-49: 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 

(estimated) July 27, 1940; 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, 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. Assistance with two discharge measurements furnished by Corps of Engineers.

Records available.- October 1942 to September 1949.

Extremes.- Maximum discharge during year, 1,600 second-feet Jan. 29 (gage height, 6.05 

feet); minimum, 0.2 second-foot Oct. 17, 18, 19 (gage height, 1.05 feet).

1942-49: Maximum discharge, 8,170 second-feet Aug. 5, 1943 (gage height, 15.90 

feet, from graph based on gage readings); minimum, 0.1 second-foot Oct. 5, 1947.

A stage of 17.0 feet occurred in May 1933, and is said to have been the highest 

within the last 30 years.

Remarks.- Records fair except those for periods of ice effect or indefinite stage-discharge 

relation, which are poor. Gage read twice daily. An average of 1.4 second-feet, diverted half a mile above station for water supply of city of Pontiac, is not included
