SURFACE WATER SUPPLY OF HUDSON BAY AND UPPER MISSISSIPPI RIVER BASINS, 1942

 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, 1942. 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 9,400 gaging stations 

In the United States and also at many gaging stations In Alaska and Hawaii. In July 1942, 

4,970 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 11.

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 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 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

v 

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, 1942, PART 5

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 dally flow. The records of stage are obtained either from 

direct readings on a nonrecordlng 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 i.

Rating tables giving the discharge for any stage are prepared from the discharge measurements. The application of the dally 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 dally 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 dally 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 ae 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. 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 ttie table by symbols referring to footnotes 

or are given In a general note following the table.

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 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, 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 is 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 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 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 o_f 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 J.O 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 dually 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 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.

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 and 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 saverage 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 some 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.

TIME BASIS

At 2 a.m. on February 9, 1942, as an emergency measure, the Nation shifted from 

standard time to "war time," and clock time in the several zones of the country was moved 

ahead 1 hour, or to 3 a.m. This made February 9 a 23-hour day. Time prior to 2 a.m.
4 SURFACE WATER SUPPLY, 1942, PART 5

February 9 as given herein refers to standard time; time after 2 a.m. February 9 refers 

to war time. To convert war time to standard time, subtract 1 hour.

Records of dally discharge prior to February 9, 1942, published herein have been computed on the basis of standard time. Records subsequent to that date have been computed 

on the basis of war time. The discharge given for February 9 Is the mean for 23 hours. 

The mean discharge and runoff for the month of February have been computed from the-total 

second-foot-days for the month without adjustment for the fact that February 9 was a 

23-nour day. The small error resulting from this procedure has been disregarded.

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 

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. The records of monthl^ and yearly mean discharge and runoff are, In 

general, more accurate than the dally 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 "secondfeet 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 of reservoirs or for other 

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

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 tor 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.

Papers on surface water supply containing records from 1899 to date, grouped by years 

and drainage basins, are listed by number on page 7. The data for any particular 

station will, In general, be found In the reports covering the years during 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, and 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. 7), 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.

studies of runoff from seven areas in Wisconsin and four in Illinois. Three of. the areas in 

Wisconsin, comprising leaa than 5 acres each, are nsar La Crosse (study began in 1932), and the 

other four, comprising less than 330 acres each, are near Pennimore (study began in 193S). The 

four areas in Illinois, comprising less than 300 acres each, are near Edwardsvllle (study began in 

1938). Records of these studies are in the files of the Soil Conservation Service.

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

the operation of 148 gaging stations, of which 49 were In Illinois, 32 In Iowa, 36 in 

Minnesota, 11 In Missouri, "S In North Dakota, 2 In South Dakota, and 12 In Wisconsin.

Financial assistance was also furnished by the Fish and Wildlife Service, United States 

Department of the Interior, and the Weather Bureau, United States Department of Commerce.

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, Canaaa. 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 municipalities, 

organizations, and corporations:

Average discharge.- 50 years (1892-1942), 8,842 second-feet (adjusted for diversion).

Extremes.- Maximum discharge during year, 30,300 second-feet May 20 (gage height, 9.18

 feet); minimum daily, 2,900 second-feet Dec. 12.

1887-1942: 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. S. Army,

Remarks.- Records excellent. Flow partly regulated by Government reservoirs on head-

 waters and power plants. 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.

miles downstream from Yellow River. Datum of gage Is 605.30 feet above mean sea 

. level, adjustment of 1912. Auxiliary water-stage recorder at dam 9, 2i miles northeast of Harpers Ferry and 14.2 miles upstream from base gage. Datum of gage Is 600.00 

 feet above mean sea level, adjustment of 1912.

Drainage area.- 67,500 square miles.

Records available.- August 1936 to September 1942.

Extremes.- Maximum dally discharge during year, 113,800 second-feet June 7; maximum gage 

neignt, 17.38 feet June 9; minimum dally discharge, 13,000 second*feet Jan. 13; 

minimum gage height, 6.37 feet Aug. 27.

1936-42: Maximum daily discharge, that of June 7, 1942; maximum gage .height 

observed, 18.45 feet Sept. 18, 1938; minimum dally discharge, 6,200 second-feet Dec. 9, 

1936 (discharge measurement); minimum gage height, -0.86 foot Aug. 18, 1936.

Maximum stage known, about 21.0 feet In 1880.

Remarks.- Records good except those for periods of ice effect, which are fair. Stageaiscnarge relation affected by backwater from Wisconsin River and dam 10. Discharge 

computed by using fall as determined by auxiliary water-stage recorder as a factor. 

Plow regulated by reservoirs and navigation dams. '

CHIPPEWA RIVER BASIN 129

Reservoirs In the Chlppewa River Basin

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

Chlppewa, Flambeau and Red Cedar Rivers. Mpose 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 Coifax, 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 draw-down is limited 

In the Interests of riparian property owners.

Moose Lake, on West Fork of Chlppewa River, In sec. 14, T. 41 N. f 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 J.,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 Chippewa River, in sec. 3, T. 28 N., R. 8 W., 3 miles east of Chippewa

 Falls. Urainage 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 Birchwood, 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 90S 

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

 Hlkana, 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.

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

has usable capacity of 413 million cubic feet.

210 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; Minocqua, 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. Minocqua, Squirrel Lake, Willow Reservoir, and Rice 

Reservoir also regulate the f]£w of the Tomahawk River upstream from the 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.

(estimated) July 27, 1940; minimum gage height observed, 4.21 feet July 25, 1940.

Remarks.- Records good except those for periods of Ice effect, which are fal'r. On Raccoon 

River, about 2& miles above station, water for municipal supply of Des Molnes 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 Molnes River about 3 miles below 

station, not measured but reported to roughly correspond to pumpages except following 

heavy local rains. Net effect of pumpages, storm water, and other diversions not known.

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

rumisnea by Des Molnes Water Works and by city of Des Molnes. Water-stage recorder 

Inspected by employee of Des Molnes Water Works.

p Computed from gage-height record furnished by Illinois-Iowa Power Co. 

Time baa 1st Central standard time prior to 2 a.m., Feb. 9, 1942; central war time thereafter. 

To convert war time to standard time, subtract 1 hour.
340 ILLINOIS RIVER BASIN 

Illinois River at Kingston Mines, 111.

Location.- Water-stage recorder, lat. 40°33'10", long. 89°46'40", in SEiSEi serf. 26, T. 

7 N., R. 6 E., at Kingston Mines, 2.3 miles downstream from Mackinaw River and 145.3 

miles (corrected) upstream from mouth. Prior to Apr. 1, 1942, staff gage at same site 

and datum. Auxiliary water-stage recorder at mouth of Copperas Creek, 0.5 mile upstream from abandoned Copperas Creek lock, 7.9 miles downstream from base gage, and 

16.9 miles upstream from Spoon River. Prior to Dec. 23, 1941, staff gage 0.5 mile 

downstream at same datum. Datum of all gages is 428.00 feet above mean sea level, 

datum of 1929 (levels by Corps of Engineers, U. S. Army).

Records available.- October 1939 to September 1942.

Extremes.- Maximum discharge observed during year, 53,600 second-feet Feb. 9; maximum 

gage height observed,, 17. 85 feet Feb. 13; minimum daily discharge, 2,620 second-feet 

Aug. 20; minimum gage height recorded, 2.35 feet Aug. 20.

1939-42: Maximum discharge observed, that of Feb. 9, 1942; maximum gage height 

observed, that of Feb. 13, 1942; minimum daily discharge observed, that of Aug. 20, 

1942; minimum gage height observed, 1.75 feet Oct. 5, 6, 19, 1939.

Remarks . - Records fair. Prior to installation of recorder, gages read once daily. Discnarge computed by using fall as determined by auxiliary water-stage recorder as a 

factor. ^

Cooperation.- Twenty-two discharge measurements furnished by Corps of Engineers, U. 

Army. ~

342 ILLINOIS RIVER BASIN

Chicago Sanitary and Ship Canal at Lockport, 111.

Location.- Lat. 41 034'11", long. 88°04'42", In SWi sec. 27, T. 36 N., R. 10 E., at upper 

end of 9-foot navigation channel In Des Plalnes River at Lockport.

Records available.- October 1936 to September 1942 In reports of Geological Survey.

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

Illinois".

Average discharge.- 42 years, 6,954 second-feet.

Extremes.- Maximum total discharge during year, 16,881 second-feet Feb. 6; minimum total, 

489 second-feet Sept. 7.

1900-1942: Maximum total discharge, 19,182 second-feet Sept. 13, 1936; minimum 

total, 91 second-feet Dec. 15, 1938.

Corrections.- Minimum total discharge for water year 1940 has been corrected to 

323 second-feet Feb. 3, 1940, superseding figure published in Water-Supply Paper 895. 

Minimum total discharge for period 1900-1941 has been corrected to 91 second-feet 

Dec. 15, 1938, superseding erroneous figure and date published in Water-Supply Paper 

925.

Remarks.- Total daily discharge Includes governmental and private pumpage, inflow from 

Des Plaines River at Willow Springs and Romeo, storm water runoff drainage Into main 

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

the 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 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 total discharge the Chicago 

punpage and inflow from Des Plaines River. This diversion includes runoff 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.

Cooperation.- Records furnished by the Sanitary District of Chicago.

 Money Creek at Lake Bloorolngton, 111.

Location.- Water-stage recorder and artificial control. 1,300 feet downstream from dam 

 at Lake Bloomington, lat. 40°39'47", long. 88°56'23*, in NWi sec. 1, T. 25 N., R. 2 

E., 2.1 miles upstream from mouth and 4 miles northeast of Hudson. Datum of gage is 

678.05 feet above mean sea letfel. Auxiliary water-stage recorder in pumping plant 

Just upstream from dam gives stage of lake. Datum of auxiliary gage is 700.00 feet 

above mean sea level.

Correction.- Distance of pumping plant upstream from mouth has been corrected to 

2.4 miles superseding erroneous figure of 2.8 miles published in previous water-supply 

papers.

Drainage area.- 61 square miles.

Records available.- October 1930 to September 1942.

Average runoff.- 12 years, 7,411.6 million gallons per year, adjusted (equivalent 

secona-reet, 31.4).

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

53T~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.

Cooperation.- Pumpage record furnished by city of Bloomington.
