SURFACE WATER SUPPLY OF HUDSON BAY AND UPPER MISSISSIPPI RIVER BASINS, 1940

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, 1940. The work was begun In 1888 In connection with special studies 

relating to Irrigation. Measurements of the flow of streams and or the stage and contents 

of lakes and reservoirs have been made at about 8,800 gaging stations In the United States 

and also ato many gaging, stations In Alaska and Hawaii. In July 1940, 4,760 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-feet11 is an abbreviation for "cubic feet per second," A second-fcot is the 

rate of discharge of a stream whose channel is 1- square foot In cross-sectioral 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-day11 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 0.0373 inch from one square mile.

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

discharge."

"Control" is a term used to designate a feature below the gage that defines the stagedischarge relation at the gage. This feature may be a natural section, a reach of the 

channel, or an artificial structure.

EXPLANATION OF DATA

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

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

measurements In determining the daily 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 1.

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

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

For most of the gaging stations 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 except for those stations whose 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 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. Likewise the minimum discharge represents the lowest stage, unless otherwise qualified. The peak discharge for 

the year with the time of its occurrence is given below the table of monthly discharge for 

some stations. Selected lower peaks are also given if the peak discharge exceeded the 

mean discharge for that day by more than 10 percent. This supplementary Information is 

generally not given for stations having drainage areas of less than 10 square miles or 

more than 10,000 square miles.

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

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

twice-daily readings. For flashy floods the mean dally discharge is determined fron gageheight 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 mean daily gage height. For stations subject to such fluctuation the mean 

dally gage height may not indicate the true mean daily discharge, which must be obtained 

by averaging the discharge for intervals of the day or by using the discharge Integrator, 

an instrument for obtaining the mean dally discharge from a continuous gage-height graph 

and containing as an essential element the rating curve of the station.

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 

or fall in a reach of the stream as a factor In the determination of discharge. Information requisite for determining the slope or fall is obtained by means of an auxiliary

EXPLANATION OF DATA 3

gage set at some distance from the base gage. The auxiliary gage, If one Is used, Is 

described under "Location." 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 seme 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 occasional winter discharge 

measurements and gage heights, 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.

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

for each month of the figures for that month given In the table of dally discharge. The 

column headed "Maximum" gives the maximum dally discharge and not the Instantaneous 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.

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 observation 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 "se-xmd-feet per 

square mile" and "run-off In Inches" are not published unless storage or dlve-slon 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 run-off In inches 

are also omitted If the drainage area Includes large noncontrlbuting 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 gives a general Idea of the flow at the station. The 

table of dally discharge allows more detailed studies of the variation In flew. It should 

be borne in mind, however, that the obeervatlons In each succeeding year may be expected

to throw new light on data previously published, and that greater degreee of refinement 

In computations and records may be warranted with the Increase In data and the use of 

Improved equipment.

Note.- Reports containing records for years after 1901 are given in table on page 6.

The table on the following page gives, by years and drainage basins, the numbers of 

the papers on surface water supply published from 1899 to 1940. 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, 503, which contain records for the Ohio River Basin for those years.

The records at most of the stations discussed in these reports extend ove~ 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 measure-nents" 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.

miles downstream from U. S. Highway 30 (published as Mississippi River at Le Claire). 

Records equivalent except for Inflow from Wapslplnlcon River.

Extremes:- Maximum dally discharge during year, 74,100 second-feet June 19; maximum gage 

height, 10.36 feet June 19; minimum dally discharge, 12,000 second-feet (estimated) 

Dec. 27-30; minimum gage height, -0.70 foot Dec. 30.

Maximum stage known, 19.7 feet June 25, 1880 (21.4 feet at Camanche).

Remarks.- Records good except those for Dec. 13 to Mar. 17, which are fair. Stagedischarge relation affected by backwater from Wapslplnlcon River and drm 14. Discharge 

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

Flow regulated by reservoirs and navigation dams.

adjustment of 1929). Prior to July 11, 1940, various combinations of gfges were 

used.

Drainage area.- 171,500 square miles.

Records avallable.- March 1933 to January 1938 and October 1939 to September 1940 in re-

 ports of U. S. Geological Survey. Daily gage heights have been published in reports 

of Mississippi River Commission since January 1904, in reports of U. S. Weather Bureau 

December 1890 to September 1893 and since January 1917. Discharge measurements made 

intermittently by Mississippi River Commission and Corps of Engineers, U. S. Army 

since 1880 at Orafton, 15 miles upstream, are published in reports of those 

organizations.

Extremes.- Maximum discharge during year, 137,000 second-feet Apr. 19 (gage height,

407.10 feet); minimum observed, 16,300 second-feet Oct. 1; minimum gage height, 390.8 

feet Jan. 15.

1933-38, 1939-40: Maximum discharge observed, 265,000 second-feet May 17, 1933; 

maximum gage height observed, 424.4 feet June 8, 1935; minimum discharge, 15,000 

second-feet Dec. 30, 1933; minimum gage height, that of Jan. 15, 1940. 

Maximum stage known, 432.5 feet in June 1844.

19, T. 117 N., R. 40 W., at bridge on U. S. Highway 212, across river from Montevideo 

and 500 feet below Chlppewa River. Datum of gage Is 910.87 feet above mean sea level 

(general adjustment of 1912).

Drainage area.- 6,090 square miles (revised). 

Records available.- July 1909 to September 1940. 

Average discharge.- 31 years, 455 second-feet.

Extremes.- Maximum discharge during year, 2,220 second-feet Apr. 10 (gage height, 10.29 

feet); minimum, 11 second-feet Dec. 13 (gage height, 1.92 feet, affected by debris on 

control).

1909-40: Maximum discharge, 22,000 second-feet June 25, 1919 (gage height, about 

18.85 feet, from floodmarks) computed by A. F. Meyer, consulting engineer, Minneapolis, 

Mlnn.; no flow for several days In 1933, 1934, and 1936.

Remarks.- Records excellent except those affected by backwater, which are good, and those 

for periods of no gage-height record, which are poor. Flow regulated by Lac qul Parle 

and Big Stone and several smallar lakes above gage.

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

The discharge as computed was checked within 4 percent 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 

considerable too low.

132 CHIPPEWA RIVER BASIN

Reservoirs in the Chippewa River Basin

The nine reservoirs listed below are used to stabilize flow of the Chiprewa, Flambeau, 

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

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

by the Chippewa-Flambeau Improvement Co.; Wissota Reservoir, which regulates flow above 

station on Chippewa River at Chippewa Falls; and the four reservoirs Birch Lake, Cedar 

Lake, Long Lake, and Bear Lake, which regulate flow above station on Red Cedar River 

near Colfax, are operated by the Northern States Power Co., who also furnish the records 

of gage heights and contents for all the above reservoirs. The usable capacity of those 

reservoirs usually is 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 Chippewa 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.

Chippewa Reservoir on Chippewa River, in sec. 2, T. 39 N., R. 6 W., 6 miles northeast

 o? 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 moan sea level 

(Northern States Power Co. bench mark). .

Rest Lake on Manltowisn 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 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 1,573,0 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 Wissota on Chippewa River, In sec. 3, T. 28 N., R. 8 W., 3 miles east of Chippewa

 fells. Urainage area, 5,548 square miles, used as reservoir since 1917, has usable 

capacity of 3,547 million cubic feet at elevation 89S.O 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. bemh 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 

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 milllOT cubic feet 

in summer and 577 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 In winter.

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

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

Average discharge.- 19 years (1913-16, 1919-27, 1929-30, 1933-40), 784 second-feet.

Extremes.- Maximum discharge during year, 26,100 second-feet July 27 (gage height, 25.29 

feet}, from rating curve extended above 9,000 second-feet on basis of measurement at 

peak of flood, made near Millville, 14 miles below; minimum, 49 second-fset Jan. 28, 

29; minimum gage height observed, 3.52 feet Dec. 22

1915-16, 1919-27, 1929-30, 1932-40: Maximum discharge observed, 26,600 second-feet 

Feb. 23, 1922 (gage height, 28.06 feet, from floodmarks) from rating cur-re extended 

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

Remarks.- Records good except those for periods of ice effect and those for periods when 

tne gage height was partly or wholly estimated, which are poor. Slight diurnal 

fluctuation caused by hydroelectric plant at Elkader.

Cooperation.- Results of two discharge measurements furnished by Corps of Eigineers, 

U. S. Amy.

Records available.- December 1933 to September 1940. November 1914 to September 1934 

at Lyndon, 16£ miles downstream (drainage area, 9,010 square miles).

Average discharge.- 26 years, 5,287 second-feet (discharge for site at Lyitfon adjusted 

for difference In drainage area).

Extremes.- Ifeximum discharge during year, 17,200 second-feet Aug. 28 (gage height, 7.50 

feet); minimum dally, 530 second-feet Jan. 1.

1914-40: Ifeximum discharge, 51,000 second-feet Feb. 22, 1937, at lower dam at 

Rock Falls, from rating curve extended above 21,000 second-feet by logarithmic plotting; minimum dally, 440 second-feet Aug. 20, 1934.

Remarks.- Records excellent except those for periods of Ice effect or no ga.ge-helght 

record, which are good. About 100 second-feet diverted above gage to Illinois and 

Mississippi Canal. Some diurnal fluctuations caused by power plants abcve station.

Cooperation.- Results of one discharge measurement furnished by Corps of Engineers, 

U.S. Army.

» Winter discharge measurement made on this day.

Note.- Stage-discharge relation affected by Ice Jan. 1 to Feb. 11. Incomplete gage-height record 

Oct. &6 to Nov. 10, Jan. 5-26, June 17-19, July 12-17, 25-30; discharge computed on t«sls of staffgage readings.
ILLINOIS RIVER BASIN 291

Chicago Sanitary-and Ship Canal at Lockport, 111.

Location.- Lat. 41°34 I 11", long. 88°04'4211 , in SWi sec. 27, T. 36 N., R. 10 E., at upper

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

Records available.- October 1936 to September 1940 in reports of Geological Survey.

 January 1900 to September 1936 in State report entitled "Stream-flow drta of Illinois'1 , 

1937.

Average discharge.- 40 years, 7,132 second-feet.

Extremes.- Maximum total discharge during year, 13,694 second-feet Oct. 2f; minimum total, 

32.3 second-feet Feb. 3.

1900-40: Maximum total discharge, 19,182 second-feet Sept. 13, 193f; minimum, 91 

second-feet Dec. 15, 1938.

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

 Plaines River at Willow Springs and Romeo, storm-water runoff draining 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 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. Prior to May 1940, Chicago pumpage included runoff from Des Plaines 

River Basin which entered Sanitary District sewers.

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

pumpage and the inflow from the Des Plaines River. Subsequent to May 1940, 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 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 Sanitary District of Chicago.

Discharge, In second-feet, water year October 1939 to September 1940
