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, 1941. 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 9,120 gaging stations 

In the United States and also at many gaging stations In Alaska and Hawaii. In July 1941, 

4,850 gaging stations were being maintained by the Geological Survey and cooperating organizations . Miscellaneous discharge measurements were made 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 acknowledged in connection with the description of each station affected; cooperation of the second kind Is acknowledged on page 10.

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 run-off Is distributed uniformly both as regards time and area.

"Run-off 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 run-off 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 and 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 run-off 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 etructure.

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

2 EXPLANATION OF DATA

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 on plate 1.

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

dally 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 are used in applying the gage heights to the rating tables.

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 la 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 

tne 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. The days 

included in the periods of ice effect and the days during the winter period on which discharge measurements were made are Indicated in the table by symbols referring to footnotes.

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 dally discharge of 

the stream, and a table of monthly and yearly discharge and run-off. 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, Its latitude and longitude 

determined from the best available maps, and information in regard to diversions that 

decrease the flow at the gage, artificial regulation from pondage or storage, and the 

accuracy of the records. Under "Average discharge" is given the average discharge for the 

number of years indicated. It le given only for stations for which there are 10 or more 

complete years of record. 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 (unlese 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 nonrecording gage read at the time of the crest. Likewise the minimum discharge represents the lowest stage, unless otherwise qualified. Selected peak discharges 

with the times of their occurrence are given below the table of monthly discharge for some 

stations. This supplementary information is generally omitted for stations having drainage areas of less than 10 square miles or more than 10,000 square miles or if the peak 

discharges usually exceed the corresponding mean discharges for the day by less than 10 

percent.

For stations equipped with nonrecording gages, the table of daily discharge gives 

the discharge In second-feet corresponding to once-daily readings of the gage or the mean 

of twice-daily readings. For flashy floods the dally mean discharge is determined from 

gage-height graphs based on gage readings made once or twice daily or oftener, as stated 

in the station description. 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 dally 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.

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 dally 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 dally discharge. The column headed "Mean" gives the average flow 

In cubic feet per second during the month.

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 a few of the 

more Important lakes and reservoirs a table showing daily contents 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 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 dally records are accurate within 

5 percent; "good," within 10 percent; "fair," within 15 percent; and "poor," within 20 or 

a higher percent.

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 "secondfeet per square mile" and "run-off in Inches" are not published unless storage or diversion 

records are Included indicating the extent of the regulation or diversion or unless
4 ACCURACY OF FIELD DATA AND COMPUTED RESULTS

satisfactory adjustments can be made for changes In contents of reservoirs or for other 

changes Incident to use and control. Figures of second-feet per square mile and run-off 

In Inches are also omitted if the drainage area Includes large noncontrlbutlng areas or 

if the average annual rainfall over the drainage area is less than 20 Inches.

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 dally 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.

which the station was maintained. For example, the data for 1910 to 1920 for any station 

in the area covered by part 3 are published in Water-Supply Papers 283, 303, 323, 353, 

403, 433, 453, 473, 503, which contain records for the Ohio River Basin for those years.

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. 6), contains a summary of yearly discharge at gaging 

stations in the area covered by that report. Gaging stations at which 10 or more complete years of record have been collected are represented. These summaries are available 

also as separate reprints.

From tine to time 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 in alphabetical order by States and drainage 

basins.

10 COOPERATION

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

Illinois: Department of Registration and Education, J. J. Hallihan, 

director, through the Division of Water Survey, Dr. A. M. Buswell, chief; and 

Department of Public Works and Buildings, W. A. Rosenfleld, director, through 

the Division of Waterways, Carter Jenkins, chief engineer.

Indiana: Department of Public Works, V. M. Simmons, administrative officer, 

prior to July 1, 1941; Department of Conservation, F. H. Wallace, acting commissioner, and State Highway Commission, J. D. Adams, chairman, thereafter. 

Iowa: Iowa Geological Survey, A. C. Trowbrldge, director; University of 

Iowa Institute of Hydraulic Research, F. M. Dawson, director and dean of 

College of Engineering, and E. W. Lane, associate director; and State Conservation Commission, M. L. Hutton, director, succeeded by F. T. Schwob.

Minnesota: Department of Conservation, Division of Water Resources and Engineering, W. S. Olson, director.

Missouri: Missouri Geological Survey and Water Resources, H. A. Buehler, 

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

North Dakota: Office of State engineer, E. J. Thomas.

Wisconsin: Public Service Commission, G. P. Steinmetz, chief engineer; and 

Wisconsin Statutory Committee on Water Pollution, Adolph Kanneberg, chairman. 

Financial assistance was furnished by the Corps of Engineers, United States Army, in 

the operation of 143 gaging stations, of which 50 were In Illinois, 32 in Iowa, 31 in 

Minnesota, 10 in Missouri, 7 in North Dakota, 1 in South Dakota, and 12 in Wisconsin.

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

United States Department of the Interior.

Several 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 Dominion Water and Power 

Bureau, Department of Mines and Resources, Canada. On waters adjacent to the international boundary, certain stations are maintained Jointly by the United States and 

Canada under the terras 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 municipalities, 

organizations, and corporations:

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

Side Levee and Sanitary District.

Iowa: Mississippi River Power Co., Interstate Power Co., Central States 

Electric Co., Central States Power and Light Corporation, Iowa Electric Co., 

Iowa Electric Light & Power Co., Des Moines Electric Co., Des Moines Waterworks, Jacob E. Decker & Sons, Boone Water Department, Iowa State College, and 

the cities of Des Moines, Ottumwa, Waterloo, and Cedar Rapids.

Wisconsin: Northern States Power Co. and Wisconsin Public Service Corporation.
DIVISION OF WORK n

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

Survey, Glenn L. Parker, chief hydraulic engineer, Carl 0. Paulsen, assistant chief hydraulic engineer, and Rudolph 0. Kasel, chief of the division of surface waters.

The data lof 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 Thebes, Kaskaskia River at Carlyle, and for stations on 

Galena, Apple, and Plum Rivers), J. H. Morgan; in Indiana, H. E. Grosbach until September 

15, 1941, succeeded by D. M. Corbett; In Iowa and for stations on Galena, Apple, and Plum 

Rivers In Illinois, L. C. Crawford; in Minnesota (except for St. Croix River near Rush 

City), In North Dakota, for Mississippi River at Prescott and at La Crosse, Wis., and for 

Whetstone River near Big Stone, S. Dak., P. R. Speer; in Missouri, for Kaskaskia River at 

Carlyle, 111., and for Mississippi River at Alton and Thebes, 111., H. C. Beckman; in 

Montana, A. H. Tuttle; in Wisconsin (except for Mississippi River at Prescott and La 

Crosse), for St. Croix River near Rush City, Mlnn., and for East Fork of Galena River at 

Council Hill, 111., F. C. Christopherson.

The records were reviewed and the manuscript prepared for publication under the direction of B. J. Peterson, engineer in charge, and M. C. Boyer, associate engineer, section 

of reports.

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

K. &. 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, 

lat. 93 001'45", long. 44°53'4511 , In SEi 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 1941.

Average discharge.- 49 years (1892-1941), 8,796 second-feet (adjusted for diversion).

Extremes.- Maximum discharge during year, 39,400 second-feet Apr. 11-14 (gage height, 

11.47 feet); minimum dally, 1,890 second-feet Nov. 13.

1887-1941: Maximum discharge, 80,800 second-feet Apr. 6, 1897 (gage height, 18.0 

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

Maximum discharge known, 107,000 second-feet Apr. 29, 1881 (gage height, 19.6 

feet), determined by Corps of Engineers, U. 3. Army.

Remarks.- Records good. Partial regulation by Government reservoirs on headwaters and 

power plants upstream. Stage-discharge relation affected most of year by backwater 

from Hastings Dam. 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 dally discharge do not Include this diversion.

Cooperation.- Records of Mississippi River at Twin City Lock and Dam furnished by Ford 

Motor co.

is 563.21 fs&t above mean sea level, adjustment of 1912.

Drainage area,- 85,600 square miles at U. S. Highway 30, where discharge "leasurements are 

made"^

Records available^- October 1939 to September 1941. October 1932 to September 1939 in 

reports of Geological Survey and June 1873 to December 1932 in report of Iowa State 

Planning Board entitled "Stream Flow Records of Iowa - 1873-1932", for site 23 miles 

downstream from U. S. Highway 30 (published as Mississippi River at LeClaire). Records 

equivalent except for Inflow from Wapslpinicon River.

Extremes.- Maximum dally discharge during year, 128,200 second-feet Apr. 25; maximum gage

 height, 15.11 feet Apr. £5; minimum dally discharge, 14,800 second-feet Aug. 28; minimum gage height, 2.95 feet Dec. 31.

1929, Aug. 2, 1933.

Remarks.- Records good except those below 100 second-feet, which are fair. Records of 

dally discharge computed on basis of average dally load, head, and plant efficiency. 

The discharge as computed was checked within 4 per cent by three discharge measurements made In June 1940 by the Geological Survey. A fourth discharge measurement at 

zero load Indicated that the flow as computed during no load conditions may be considerably low.

Cooperation.- Records of dally discharge furnished by Northern States Power Co.

172 RESERVOIRS IN THE CHIPPEWA RIVER BASIN

The nine reservoirs In Wisconsin listed below are used to stabilize flow of the 

Chlppewa, Flambeau and Red Cedar Rivers. Moose Lake and Chlppewa Reservoir, which regulate flow above station on Chlppewa River at Bishops Bridge, and Rest Lake and Flambeau 

Reservoir, which regulate flow above station on Flambeau River at Flambeau Reservoir, 

are operated by the Chlppewa-Flambeau Improvement Co.; Wlssota Reservoir, which regulates 

flow above station on Chlppewa River at Chlppewa Falls, and Birch, Cedar, Long and Bear 

Lakes, which regulate flow above station on Red Cedar River near Colfax, are operated by 

the Northern States Power Co., Eau Claire, Wisconsin, who also furnish the gage heights 

and contents for all the above reservoirs. The usable capacity of these reservoirs is 

usually less In summer than In winter because the allowable summer drawdown Is' limited 

In the interests of riparian property owners.

Moose Lake, on West Fork of Chlppewa River, In sec. 14, T. 41 N., R. 6 W., 20 miles east 

 of Hayward, completed In 1893, has usable capacity of 400 million cubic feet In winter, 

none In summer.

Chlppewa Reservoir, on Chlppewa River, In sec. 2, T. 39 N., R. 6 W., 6 miles northeast of 

Winter.Drainage area, 763 square miles. Reservoir completed in 1923, has usable 

capacity of 9,650 million cubic feet at elevation 1,313.0 feet, which is limit set by 

Public Service Commission of Wisconsin. Datum of chain gage Is at mean sea level 

(Northern States Power Co. bench mark).

Rest Lake, on Manitowish River, in sec. 9, T. 42 N., R. 5 E., 7 miles east of Manitowish, 

used as reservoir since 1887, has usable capacity of 260 million cubic feet in summer 

and 660 million cubic feet in winter.

Flambeau Reservoir, on North Fork of Flambeau River, in sec. 34, T. 42 N., R. 2 E., 13 

miles east of Butternut. Drainage area, 647 square miles. Reservoir completed In 1926, 

has usable capacity of 5,740 million cubic feet at elevation 1,572.0 feet, which is 

limit set by Public Service Commission of Wisconsin. Datum of staff gage Is at mean 

sea level (Northern States Power Co. bench mark).

Lake Wlssota, on Chlppewa River, in sec. 3, T. 28 N., R. 8 W., 3 miles east of Chippewa 

falls'. Drainage area, 5,548 square miles. Used as reservoir since 1917, has usable 

capacity of 3,547 million cubic feet at elevation 898.0 feet, which is limit set by 

Public Service Commission of Wisconsin; no usable storage available in summer. Datum 

of float gage is at mean sea level (Northern States Power Co. bench mark). This reservoir is used principally as a service pond for power generation.

Birch Lake, on Red Cedar River at Blrchwood, In sec. 25, T. 37 N., R. 10 W., used as 

reservoir since 1882, has usable capacity of 669 million cubic feet in summer and 908 

million cubic feet in winter. '

Cedar Lake, on Red Cedar River, in sec. 22, T. 36 N.. R. 10 W., half a mile south of 

Mikana, used as reservoir since 1882, has usable capacity of 359 million cubic feet 

in summer and 577 million cubic feet in winter.

Long Lake, on Brill River, in sec. 24, T. 37 N., R. 11 W., 5 miles north of Brill, used 

as reservoir since 1883, has usable capacity of 386 million cubic feet in summer and 

637 million cubic feet in winter.

Bear Lake, on Bear Creek, In sec. 18, T. 36 N., R. 11 W., at Haugen, used as reservoir 

since 1880, has usable capacity of 413 million cubic feet.

206 WISCONSIN RIVER BASIN

Reservoirs In the Wisconsin River Basin

The 21 reservoirs listed below are used to stabilize flow of the Wisconsin and 

Tomahawk Rivers. The reservoirs are owned and operated by the 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: 

The first thirteen are on the Wisconsin River or on tributaries that enter upstream from 

station at Rainbow Reservoir near Lake Tomahawk; North and South Pelican on tributaries 

that enter upstream from station at Whirlpool Rapids near Rhinelander; Mlnocqua, Squirrel 

Lake, Willow Reservoir, Rice Reservoir, and Spirit Reservoir on tributaries that enter 

upstream from station at Merrill; Big Eau Pleine Reservoir on a tributary that enters upstream from station at Knowlton. Mlnocqua, Squirrel Lake, Willow Reservoir, and Rice 

Reservoir also regulate the flow of the Tomahawk River above the station at Tomahawk. 

The usable capacity of these reservoirs is usually less In summer than in winter because the allowable summer drawdown Is limited in the Interests of riparian property 

owners.

downstream from Elk Creek, and 1 mile downstream from Volga River. Datum of gage is 

635.34 feet above mean sea level, adjustment of 1912.

Drainage area.- 1,530 square miles.

Records available.- August 1913 to November 1916, May 1919 to September 1927 and November 

1932 to September 1941 in reports of Geological Survey. August 1913 to November 1916, 

May 1919 to September 1927 and April 1929 to September 1930 in report of Iowa State 

Planning Board entitled "Stream Flow Records of Iowa, 1873-1932."

Average discharge.- 20 years (1913-16, 1919-27, 1929-30, 1933-41), 800 second-feet.

Extremes.- Maximum discharge during year, 22,100 second-feet June 12 (gage height, 23.27

 feet), from rating curve extended above 15,000 second-feet on basis of measurement 

near Millville, 14 milss downstream, at peak of flood of July 27, 1940; minimum discharge recorded, 165 second-feet Mar. 17 (gage height, 4.27 feet).

1913-16, 1919-27, 1929-30, 1932-41: Maximum discharge observed, 26,600 second-feet 

Feb. 23, 1922 (gage height, 28.06 feet, from floodmarks), from rating curve extended 

above 11,000 second-feet; minimum observed, 46 second-feet June 29, 1934.

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

computed from wire-weight gage readings, which are fair. Slight diurnal fluctuation 

caused by hydroelectric plant at Elkader.

DES MOINES RIVER BASIN ^95 

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°36'45", in NWi 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 

Des Koines Electric Co., and Zk 'miles downstream from dam of Des Moines Water Works 

on Raccoon. River. Datum of gage is 773.74 feet above mean sea level, datum of 1929.

Drainage area.- 9,770 square miles.

Records available.- April 1940 to September 1941.

Extremes.- 1940: Maximum discharge during period April to September, 8,990 second-

 feet Aug. 30 (gage height, 6.90 feet); minimum dally, 80 second-feet (estimated) 

July £7; minimum gage height observed, 4.21 feet July 25.

1940-41: Maximum daily discharge during water year, 13,000 second-feet June 16; 

minimum discharge, 201 second-feet Sept. 1, 2 (gage height, 4.40 feet).

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

 which are fair. On Raccoon River, about 2i miles above station,- water for municipal 

supply of Des Moines is taken from infiltration galleries which 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 

and enters Des Moines River about 3 miles below station, not measured but reported 

to correspond roughly to pumpage from galleries except following heavy local rains. 

Net effect of pumpage, storm water, and other diversions not known.

Cooperation.- Average monthly pumpage from galleries, In second-feet, computed from rec-

 ords furnished by Des Moines Water Works; water-stage recorder inspected by employee 

of that agency.

1915-41: Maximum discharge observed, 40,000 second-feet Sept. 20, 1926 (gage 

height, 18.96 feet), from rating curve extended above 22,000 second-feet; minimum discharge, 10 second-feet Jan. 22-31, 1940.

Remarks.- Records good except those for periods of fragmentary gage-height record and 

tnose computed from graphs based on wire-weight gage readings, which are fair, and 

those for periods of ice effect, which are poor. Diurnal fluctuation caused by power 

plant at Adel, 10 miles above station.

Cooperation.- Gage-height record collected In cooperation with U. 8. Weather Bureau.

346 ILLINOIS RIVER BASIN

Chicago Sanitary and Ship Canal at Lockport, 111.

Location.- Lat. 4l°34'll", long. 88004'42", In SWi sec. 27, T. 36 N., R. 10 E., at upper 

ena or 9-foot navigation channel in Des Plalnes River at Lockport.

Records available.- October 1.936 to September 1941 In reports of Geological Survey. 

January 1900 to September 1936 In the 1937 State report entitled "Stream-flow data of 

Illinois"

Average discharge.- 41 years, 7,042 second-feet. »

Extremes.- Maximum total discharge during year, 14,221 second-feet Sept. 25; minimum 

total, 101 second-feet Dec. 13.

1900-1941: Maximum total discharge, 19,182 second-feet Sept. 13, 1936; minimum 

total, 32.3 second-feet Feb. 3, 1941.

Remarks.- Total dally discharge Includes governmental and private pumpage, Inflow from 

EtsTlaines River at Willow Springs and Romeo, storm-water run-off draining into main 

channel, and diversion from Lake Michigan. This total discharge Is obtained by adding 

the dally 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, and water from wells within the main-channel drainage area Including pumpage to 

municipalities served by Chicago, and approximately 90 second-feet for agencies not 

served by Chicago.

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

pumpage and the Inflow from Des Plalnes River. This diversion includes run-off from 

Des Plaines River Basin entering Sanitary District sewers, and surface flow south of 

main channel, If any, as well as Inflow at Willow Springs, at Lemont, and at Romeo.

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. A special additional diversion of 8,500 

second-feet for 10 days was authorized for Dec. 2-12, 1940.

Cooperation.- Record furnished by Sanitary District of Chicago.

Discharge, In second-feet, water year October 1940 to September 1941
