SCOPE OF WORK

This volume is one of a series of 18 reports presenting measurements of stage, discharge, and content of streams, lakes, and reservoirs in the United States during the 

water year ending September 30, 1956. Since 1888, when the United States Geological 

Survey first studied streamflow in relation to problems of irrigation, similar measurements have been made at more than 13,500 gaging stations in the 48 States and at many 

others in the Territories of Alaska and Hawaii. On September 30, 1956, the Geological 

Survey and cooperating organizations were maintaining 6,910 gaging stations, including 

those in Alaska and Hawaii. Discharge measurements only were made at many other points 

In the 1956 water year. The name of each stream measured at points other than gaging 

stations is not listed in the index to this report. Only the major basins in which measurements were made are listed under the item "Discharge measurements" in the index.

DEFINITION OF TERMS AND ABBREVIATIONS

The terms of streamflow and other hydrologic data, as used in this report, are defined 

as follows:

Cubic foot per second (cfs) 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.

Cubic feet per second per square mile (cfsm) is the average number of cubic feet of 

water flowing per second from each square mile of area drained, assuming that the runoff 

is distributed uniformly in 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. The term is 

used for comparing runoff with rainfall, which is also usually expressed in inches.

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 relation to storage for 

irrigation.

Cfs-day is the volume of water represented by a flow of 1 cubic foot per second 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 the relation between gage height and the amount of water 

flowing in a channel, expressed as volume per unit of time.

Control designates a feature downstream from the gage that determines the stagedischarge relation at the gage. This feature may be a natural constriction of the channel, 

a long reach of the channel, or an artificial structure.

Contents is the volume of water in a reservoir. Unless otherwise indicated, volume is 

computed on the basis of a level pool and does not include bank storage.

The drainage area of a stream at a specified location is that area, measured in a horizontal plane, which is so enclosed by a topographic divide that direct surface runoff from 

precipitation normally would drain by gravity into the river above the specified point. 

Figures of drainage area given herein include all closed basins, or noncontrlbuting areas, 

within the area unless otherwise noted.

WSP is used as an abbreviation for "Water-Supply Paper" in references to previously 

published reports.

DOWNSTREAM ORDER OF LISTING (JAdlNG STATIONS

Beginning with the series of reports for the water year ending September 30, 1951, the 

order of listing gaging-station records was changed. In this report, in a downstream 

direction along the main stem all stations on a tributary entering above a main-stem
4 SURFACE WATER SUPPLY, 1956, PART 5

station are listed before that station. If a tributary enters between two main-stem stations, It is listed between them. A similar order is followed in listing stations on first 

rank, second rank, and other ranks of tributaries. To Indicate the rank of any tributary 

on-which a gaging station is situated and the stream to which it is immediately tributary, 

each indention in the listing of gaging stations in the table of contents of this report 

represents one rank. This downstream "order and system of indention show which gaging stations are on tributaries between any two stations on a main stem and the rank of the tributary on which each gaging station is situated.

The order of listing used before bhe publication of the 1951 report listed first all 

stations on the main stem from headwaters toward moubh, then all stations on the uppermost 

tributary to the main stem from the tributary's source to mouth, and then all stations 

from source to mouth of the uppermost tributary to the tributary.

EXPLANATION OF DATA

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

of discharge. In addition, observations of factors affecting the stage-discharge relation, 

weather records, and other information are used to supplement base data 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 fluctuations. 

Measurements of discharge are made with a current meter by the general methods adopted by 

the Geological Survey on the basis of experience in stream gaging since 1888. These 

methods are described in Water-Supply Paper 888 and are also outlined in standard textbooks 

on the measurement of stream discharge. Typical structures in use at gaging stations are 

shown in figure 1.

Rating tables giving the discharge for any stage are prepared from stage-discharge relation curves defined by discharge measurements. If extensions to the rating curves are 

necessary to define the extremes of discharge, they are made on the basis of indirect 

determinations of peak discharge (such as slope-area or contracted-opening determinations, 

computation of flow over dams or weirs, and by other methods), velocity-area studies, and 

logarithmic plotting. 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. If the stage-discharge relation for a station is temporarily 

changed by the presence of aquatic growth or debris on the control, the daily mean discharge 

is computed by what is essentially the shifting-control method.

At some gaging stations the stage-discharge relation is affected by backwater from reservoirs, tributary streams, or other sources. This necessitates the use of the slope 

method in which the slope or fall in a reach of the stream is a factor in determining 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 stagedischarge relation is affected by changing stage. If so, the rate of change in stage is 

used as a factor in the determination of discharge.

6 SURFACE WATER SUPPLY, 1956, PART 5

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, and it becomes 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 other stations In the same or nearby basins. If the 

stage-discharge relation is affected by ice, this Information is given in a note to the 

table. No mention is made of occasional days of Ice effect if the degree of accuracy of 

daily records Is not changed.

The data herein presented generally comprise a description of the station, a skeleton 

rating table, and a table showing the dally discharge and monthly and yearly discharge and 

runoff of the stream. Records are published for the water year which begins on October 1 

and ends on September 30. A calendar for the water year 1956 is shown on page IV for the 

purpose of finding the day of the week for any date.

The description of the station gives the location, drainage area, records available, 

type and history of gages, average discharge, extremes of discharge, general remarks, and 

notations of revisions of the previously published record. The location of the gaging 

station and the drainage area are obtained from the most accurate maps available. River 

mileage, given under "Location" for some stations, Is that determined and used by the 

Corps of Engineers unless otherwise noted. Under "Records available" are given the periods for which there are published records generally equivalent to those at the present 

site. Under "Gage" are given the type of gage currently in use and the datum of the present gage above mean sea level, and a condensed history of the types, locations, and datums 

of previous gages used during the period of records available. Under "Average discharge" 

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

stations having fewer than five complete years of record or for stations where changes In 

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

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

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

of no Importance). In the first paragraph, the data given are for the complete current 

water year unless otherwise specified. In the second paragraph, the data given are for 

the periods of record within the calendar year dates In the heading (not necessarily 

those for the complete years indicated by the heading dates). Reliable information concerning major floods that have occurred outside the period of record are given in the 

third or last paragraph under "Extremes." Unless otherwise qualified, the maximum discharge corresponds to the crest stage obtained by use of a water-stage recorder, a creststage indicator, or a nonrecording gage read at the time of the crest. If the maximum 

gage height did not occur at the same time as the maximum discharge, It is given separately. Information pertaining to the accuracy of the records and conditions which affect the 

natural flow at the gaging station Is given under "Remarks."

Previously published records of some stations have been found to be In error on the 

basis of data or Information later obtained. 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
EXPLANATION OP DATA 7

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

Listed therein are all the reports in which revisions have been published, each followed 

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

years only one number is given; for instance, 1933 stands for the water year October 1, 

1932, to September 30, 1933. If no dally, monthly, or annual figures of discharge are 

concerned 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 cubic 

feet per second 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 cubic feet per second 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.

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

discharge for the greater part of the open-water period was determined by the shiftingcontrol method, the slope method, or other special methods Involving an equivalent adjustment to the gage height of more than one-tenth foot. Skeleton rating tables are generally 

not published for stations on canals.

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

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

dally mean gage height. For stations subject to such'fluctuation the dally 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 dally 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 dally discharge gives the 

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

readings, or to 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 dally discharge, the figures for the maximum day and the minimum day for 

each month are underlined. If the figure is repeated, it is underlined only on the first 

day of its occurrence.

In the monthly summary below the daily table, the line headed "Total" gives the sum of 

the dally figures; it is the total cfs-days for the month. The line headed "Mean" gives 

the average flow in cubic feet per second during the month. Runoff for the month may be 

expressed in cubic feet per second per square mile (line headed "Cfsm"), or in inches 

(line headed "In."), or in acre-feet (line headed "Ac-ft"). Figures for cubic feet per 

second per square mile and runoff in Inches are omitted if the drainage area includes 

large noncontributing areas, or if the average annual rainfall over the drainage basin is 

usually less than 20 Inches.

In the yearly summary below the monthly summary, the figures of maximum are the maximum 

daily discharges, not the momentary discharges when the water was at crest stage. Likewise , the minimums in this summary are the minimum daily discharges.
8 SURFACE WATER SUPPLY, 1956, PART 5

Peak discharges and the times of their occurrence and corresponding gage heights of 

most stations are listed below the table of daily and monthly discharge. All independent 

peaks above the selected base are given. The base discharge, which is given in parentheses, is selected so that an average of about three peaks a year will be presented. 

Peak discharges are not published for canals, ditches, drains, or for any stream for which 

the peaks are subject to substantial control by man.

Footnotes to the table of daily discharge indicate periods when discharge was computed 

or estimated by unusual or special methods during periods of no gage-height record and ice 

effect, or by other effects that reduce the degree of accuracy of the records. Days on 

which discharge measurements were made are indicated by asterisk and footnote unless they 

were made at frequent regular intervals, in which instance the general frequency of discharge measurements is given under "Remarks" in the station description.

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 published each year for all reservoirs for which records are published on 

a daily basis, but is not published for reservoirs for which only monthly data are given.

Discharge measurements and determinations of peak flows made at sites other than gaging 

stations are listed at the end of each report.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of streamflow data depends primarily on (1) the stability 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 discharge, and interpretation of records.

The station description states the degree of 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 IS percent; and "poor,'1 probably 

more than 15 percent. The records of monthly and yearly mean discharge and runoff are, 

in general, more nearly accurate than the daily records.

Runoff at some stations, as indicated by the monthly mean, may vary widely from natural 

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

evaporation due to artificial causes, or to other factors. For such stations, figures of 

cubic feet per second per square mile and runoff in inches are not published unless storage or diversion records are included to indicate 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. Evaporation from a reservoir is not 

included in the adjustments for changes in reservoir contents, unless it is so stated. 

Even at those stations where adjustments are made, large errors in computed runoff may 

occur when relatively large negative adjustments are made or when evaporation is large in 

comparison with the observed discharge

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 actually show the water supply available at the stations for further development, 

because water must first be supplied to existing irrigation systems.

The records at most of the stations discussed in these reports extend over many years. 

Discharge measurements at many points other than regular gaging stations have been made 

each year and are published at the end of each report. The streams and points of measurement are listed in the same order as the streams and gaging stations in the body of the 

report. An index of the records obtained before 1904 has been published in Water-Supply 

Paper 119.

Each of the reports on the surface water supply for the year 1939 (Water-Supply Paper 

875 for Hudson Bay and upper Mississippi River basins) contains, for the area included in 

that report, a summary of yearly discharge at gaging stations at which 10 or more complete 

years of record had been collected. These summaries were reprinted separately.

Reports also 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 may have been revised), as well as some records not contained in the 

annual series of water-supply papers. The only such report for any part of the area 

covered by this report is Water-Supply Paper 156, "Water power of northern Wisconsin."

Records of discharge have been published also in State reports. Some of these are not 

contained in the publications of the Geological Survey or are revisions of records previously published in its water-supply papers. Tne table on page 12 contains a list of 

these reports for the area covered by this report.

Note. The agricultural Research Service of the United States Department of Agriculture has collected records of runoff from five areas in Illinois, two in Missouri, and nine in Wisconsin. Four 

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

1938), and one, comprising 67Q acres, Is near Alharabra (records begin iri 1952). Two areas in Missouri, comprising less than 200 acres, is near McCredie (records begin In 1941). One area In Wisconsin, comprising 350 acres, is near Colby (records begin in 1948); four areas, comprising less 

than 4 acres, is near Fennimore (records begin In 1938); and four areas, comprising less than 

4 acres, is near LaCrosse (records begin In 1932). These records are in the files of Agricultural 

Research Service.

HYDROLOGIC CONDITIONS

During most of water year 1956 streamflow was near median in much of the area covered 

by this report. The most notable exception was in Iowa, where flow was deficient in ten 

months of the year. Monthly mean discharge of Iowa River at Marshalltown, Iowa, was 

record-low for the month In December and July. In Illinois moderate floods occurred 

during October and May. In Wisconsin major floods occurred on several rivers during April 

(the flood on Trempealeau River was the highest since at least 1914). On July 18 the peak 

discharge of Ralston Creek at Iowa City, Iowa, was the highest of record. Flow of Roseau 

River at Ross, Mlnn., was record-high for September. For three key gaging stations in the 

area covered by this report, a comparison of the monthly and yearly mean discharge during 

the 1956 water year with the median discharge for the 25-year period 1921-45 Is shown in

1902-56: Maximum discharge, 18,000 cfs (estimated) June 5, 1908; minimum daily, 

16 cfs Nov. 29, 1936.

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

which are fair. Since 1917, St. Mary Canal has diverted water from river near Babb, 

Mont., to North Pork Milk River (see p.. 27). Plow regulated by Lake Sherburne on 

Swiftcurrent Creek (see p. 24).

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

united States and Canada under the Boundary Waters Treaty. The records have been collected arid compiled jointly with the Water Resources Branch, Department of Northern 

Affairs and National Resources, Canada.

sea level, datum of 1929. May 5, 1903, to Sept. 30, 1928, Oct. 1, 1929 to Sept. 30,

1934, staff or chain gage at mile 135.0 in Minot, at datum 12.5 ft lower. Oct. 1, 1928,

to Sept. 30, 1929, staff or wire-weight gage at Saugstad Bridge, at mile 145.8, 5 miles

southeast of Minot at datum 19.2 ft lower than present datum. Records equivalent

except those for periods of extreme low flow, as some industrial and sanitary waste

enters river between sites. 

Average discharge. 43 years (1913-56), 140 cf s , unadjusted (101,400 acre-ft per year);

median of yearly mean discharges, 93 cfs (67,300 acre-ft per year). 

Extremes. Maximum discharge during year, 1,930 cfs Apr. 23 (gage height, 13.13 ft); minimum daily, 18 cfs Jan. 14-16.

1903-56: Maximum discharge, 12,000 cfs Apr. 20, 1904 (gage height, 21.9 ft, at site

in Minot), from rating curve extended above 8,100 cfs; no flow at times in some years. 

Maximum stage known at present site, about 23 ft in April 1904. Maximum stage known

in Minot at least 3 ft higher than 1904 peak, in 1881, according to Apr. 20, 1904, issue

of Minot Daily Optic. 

Remarks . --Records good except those for period of ice effect, which are fair. Plow almost

completely regulated by Lake Darling and several smaller reservoirs (combined capacity,

about 180,000 acre-ft). Some small diversions for irrigation and municipal supply. 

Revisions (water years) . WSP 1338: 1903-4, 1906, 1917, 1928.

130 RED RIVER OF THE NORTH BASIN

Souris River near Westhope, N. Dak. 

(International gaging station)

Location.--Lat 48°59'47", long 100°57'29", in SW^SE^ sec. 30, T. 164 N., R. 79 W., on left 

bank 1,200 ft upstream from second crossing of international boundary, 1 mile downstream 

from Pish and Wildlife Service dam 357, 7 miles northeast of Westhope, 11 miles downstream from Boundary Creek, and at mile 358.2 downstream from international boundary 

(Geological Survey river plan and profile).

Drainage area.--17.600 sq mi, approximately.

Records available.--July 1929 to September 1956 (no winter records prior to 1936).

Gage.--Water-stage recorder and concrete control. Datum of gage is 1,402.52 ft above mean 

sea level, datum of 1929. Prior to Mar. 23, 1938, chain gage at site 6.3 miles upstream 

at datum 2.52 ft higher.

Average discharge.--21 years (1935-56), 234 cfs (169,400 acre-ft per year), unadjusted.

Extremes.--Maximum discharge during year, 3,040 cfs May 21 (gage height, 12.35 ft); minimum daily, 1 cfs Dec. 6-15.

1929-56: Maximum discharge, 6,400 cfs Apr. 18, 1949; maximum gage height, 16.9 ft 

Apr. 20, 1949 (from floodmark); maximum daily reverse flow, 35 cfs Apr. 8, 1943, caused 

by backwater from downstream tributary inflow; no flow at times in some years.

Remarks.--Records fair except those for periods of ice effect or fragmentary gage-height 

record, which are poor. Flow regulated by Fish and Wildlife Service dams on Souris, 

DesLacs, Wintering Rivers, and Willow Creek (combined capacity, about 243,000 acre-ft). 

Diversions for irrigation of about 7,600 acres at Eaton Dam, and other small diversions 

for irrigation and municipal supply above station.

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

United States under agreement with Canada.

Revisions (water years).--WSP 1338: 1932.

MISSISSIPPI RIVER MAIN STEM

Mississippi River at St. Paul, Hinn.

Location. Lat 44°56'40", long 93"05'20", in NE£ sec. 6, T. 28 N., R. 22 W. , on left bank 

In St. Paul, 300 ft upstream from Robert Street Bridge, 6 miles downstream from 

Minnesota River, and at mile 839.3 above Ohio River.

Drainage area.--36,800 sq ml, approximately. 

Records available. March 1887 to September 1956.

Gage.--Water-stage recorder. Datum of gage Is 684.16 ft above mean sea level, adjustment 

of 1912. Prior to Mar. 16, 1925, staff gages or chain gage at several sites within 

300 ft of present site at same datum. Mar. 16, 1925, to Mar. 10, 1933, water-stage 

recorder and Mar. 11, 1933, to Aug. 18, 1939, staff gage, at present site and datum. 

Since September 1938, auxiliary water-stage recorder 7 miles downstream.

Average discharge.--64 years (1892-1956), 9,842 cfs (adjusted for diversion).

Extremes. Maximum discharge during year, 34,900 cfs Apr. 11 (gage height, 8.67 ft); minimum daily, 2,120 cfs Nov. 20.

1887-1956: Maximum discharge, 125,000 cfs Apr. 16, 1952 (gage height, 22.02 ft); 

minimum daily, 632 cfs Aug. 26, 1934.

Maximum stage known since at least 1870, that of Apr. 16, 1952. Flood of Apr. 29, 

1881, reached a stage of 19.7 ft (discharge, 107,000 cfs), determined by Corps of 

Engineers.

Remarks.--Records good. Slight regulation except during extreme floods by reservoirs on 

headwaters and by powerplants. 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 furnished by Ford Motor Co. Gage-height record at South St. Paul and gage readings on 

outside staff gage at St. Paul furnished by Corps of Engineers. Diversion through 

sewage-disposal plant furnished by Minneapolis-St. Paul Sanitary District.

Revisions (water years). WSP 715: Drainage area. WSP 875: 1938. WSP 895: 1939. 

Discharge, In cubic feet per second, water year October 1955 to September 1956

Records available.--August 1929 to September 1956 (winter records incomplete 1929-40).

Gage. Wire-weight gage read once daily. Prior to Oct. 5, 1939, chain or staff gage and 

~lJct. 5, 1939, to Jan. 11, 1954, wire-weight gage, at site 600 ft downstream at same 

datum. Altitude of gage is 1,360 ft (by barometer).

Average discharge.--16 years (1940-56), 623 cfs.

Extremes. Maximum discharge during year, 3,250 cfs Apr. 8 (gage height, 9.6 ft, from 

graph based on gage readings); minimum observed, 143 cfs Sept. 30 (gage height, 

4.98 ft).

1929-56: Maximum discharge observed, 10,200 cfs June 18, 1943 (gage height, 14.32 

ft); minimum, 39 cfs Aug. 31, Sept. 3-5, 1933.

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

for periods of no gage height record, which are poor.

CHIPPEWA RIVER BASIN 227

Reservoirs In the Chippewa River basin

The nine reservoirs listed below are used to stabilize the flow of the Chippewa, Flambeau, and Red Cedar Rivers for power utilization, and are also used for recreational purposes. The first four are operated by the Chlppewa-Flambeau Improvement Co. The remaining 

five are operated by the Northern States Power Co. which also furnishes the gage heights 

and capacity tables for all the above reservoirs. Month-end contents are computed by the 

Geological Survey. The usable capacity of these reservoirs ,1s usually less in summer than 

in winter, because the allowable summer draw-down is limited by the Public Service Commission of Wisconsin in the interest of riparian property owners. There are occasionally formal or Informal changes in capacity and in minimum draw-down levels. Usable capacity figures listed below are for winter regulation.

Average discharge. 29 years, 247 cfs.

Extremes. Maximum discharge during year, 3,650 cfs Apr. 7 (gage height, 6.40 ft); maximum 

gage height, 8.39 ft Apr. 6 (ice jam); minimum discharge, 28 cfs Nov. 17 (gage height, 

1.11 ft).

1914-26, 1939-56: Maximum discharge observed, 7,340 cfs Aug. 21, 1926 (gage height, 

7.85 ft), from rating curve extended above 6,000 cfs; minimum observed, 8 cfs July 17, 

1944 (gage height, 0.17 ft), probably result of temporary regulation.

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

265

Location.--Lat 44°03', long 90°04', In S| sec. 18, T. 18 N., R. 4 E., at Necedah powerplant 

of Wisconsin Power and Light Co., 5 miles downstream from Cranberry Creek.

Drainage area. 526 sq ml.

Records available. October 1940 to September 1956.

Gage.--Staff gage read at least twice dally. Datum of gage is ft above mean sea

Tevel, datum of 1929.

Average discharge. 16 years, 363 cfs.

Extremes.--Maximum discharge during year, 8,990 cfs Apr. 7 (gage height, 15.60 ft, from 

graph based on gage readings); minimum observed, 2 cfs Feb. 26 (gage height, 3.76 ft).

1940-56: Maximum discharge observed, 12,800 cfs Apr. 3, 1952 (gage height, 17.10 

ft); minimum observed, 1 cfs Aug. 22, Aug. 26 to Sept. 1, 1942, Aug. 12, 1943; minimum 

daily, 1.4 cfs Nov. 18, 21, 1953.

Remarks. Records fair except those below 15 cfs, which are poor. Record kept of hours 

of operation of single unit powerplant and used in computation of discharge. Water diverted periodically from Wisconsin River into Cranberry Creek basin for cranberry 

culture. Probably most of water diverted is lost by evaporation, transpiration, and 

infiltration to the ground-water reservoir. These diversions were as follows:

WISCONSIN RIVER BASIN 277 

Reservoirs in Wisconsin River basin

The 23 reservoirs listed below are used to stabilize the flow of the Wisconsin and 

Tomahawk Rivers for power utilization and are also used for recreational purposes. The 

first 21 reservoirs are owned and operated by the Wisconsin Valley Improvement Co. who furnished the gage heights and capacity tables. Revised capacity tables for all 21 reservoirs 

were received from the company in April 1957 and were used to compute month-end usable contents beginning Sept. 30, 1955. Petenwell and Castle Rock are owned and operated by the 

Wisconsin River Power Co. who furnished the gage heights and capacity tables for these two 

reservoirs. Month-end contents are computed by the Geological Survey. 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 occasionally 

formal or informal changes in capacity and in minimum draw-down levels. Usable capacity 

figures listed below are for winter regulation.

upstream from mouth.

Drainage area. 267 sq mi.

Records available.--October 1934 to September 1956. Published as "near Burton" October 

1934 to September 1947. Records published for both sites March to September 1947.

Gage.--Water-stage recorder. Datum of gage is 606.89 ft above mean sea level, adjustment 

of 1912. Oct. 17, 1934, to Sept. 30, 1947, wire-weight gage at site 6 miles upstream 

at datum 33.18 ft higher. Mar. 18, 1947, to July 27, 1949, wire-weight gage at present 

site and datum.

Average discharge.--21 years (1935-56), 169 cfs.

Extremes.--Maximum discharge during year, about 6,000 cfs Mar. 2 or 3 (gage height, 20.23 

ft, from floodmark), release from ice jam; minimum, 25 cfs Nov. 17 (result of freezeup). 

1934-56: Maximum discharge, 25,000 cfs July 16, 1950 (gage height, 24.82 ft), from 

rating curve extended above 18,000 cfs on basis of slope-area determination of peak 

flow; minimum, 21 cfs Mar. 4, 1954 (result of freezeup).

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

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

Records available. April 1933 to September 1956.

Gage. Water-stage recorder and concrete control. Datum of gage is 895.06 ft above mean 

sea level, adjustment of 1912.

Average discharge. 23 years, 188 cfs.

Extremes. Maximum discharge during year, 2,060 cfs May 28 (gage height, 8.21 ft); minimum 

daily, 23 cfs Oct. 22, Apr. 14.

1933-56: Maximum discharge, 20,000 cfs June 13, 1947 (gage height, 21.36 ft, from 

floodmarks), from rating curve extended above 9,000 cfs by velocity-area studies; minimum daily, 6 cfs June 8, 29, 1934.

Remarks.--Records good except those for periods of ice effect, reconstructed gage-height 

record, and indefinite stage-discharge relation, which are poor. Large diurnal fluctuation caused by hydroelectric plant 2 miles above station.

sea level, adjustment of 1912. Prior to May 1, 1920, chain gage 2.5 miles downstream 

at datum 7.87 ft lower. Apr. 9, 1920, to Sept. 13, 1924, chain gage 1.3 miles upstream 

at datum 1.65 ft lower. Oct. 9, 1924, to Sept. 30, 1927, chain gage 0.3 mile upstream 

at datum 6.69 ft lower. Oct. 1, 1933, to Sept. 30, 1934, staff gage at present site 

at datum 0.41 ft lower. Oct. 1, 1934, to Feb. 6, 1935, staff gage at present site and 

datum.

Average discharge.--30 years (1920-27, 1933-56), 1,690 cfs.

Extremes.--Maximum discharge during year, 1,550 cfs May 31 (gage height, 1.11 ft); minimum 

daily, 42 cfs Sept. 25, 30.

1920-27, 1933-56: Maximum discharge, 57,400 cfs June 22, 1954 (gage height, 25.35 

ft, from graph based on hourly gage readings); no flow for a short time Jan. 9, 25, 

1938, caused by manipulation of gates in control dam; minimum daily, 17 cfs Jan. 28, 

1940 (unaffected by gate operation).

Remarks. Records good except those for periods of ice effect, doubtful gage-height record, or indefinite stage-discharge relation, which are fair. Slight diurnal fluctuation caused by powerplants above station.

1940-56: Maximum discharge, 77,000 cfs June 26, 1947 (gage height, 20.8 ft in gage 

well, 21.6 ft, from outside floodmark); minimum daily, that of Nov. 28, 1955, Sept. 28, 

30, 1956.

Maximum stage known since at least 1893, that of June 26, 1947. Flood of May 31, 

1903, reached a stage of 20.9 ft (referred to site and datum of 1947 flood by flood 

profile) by Office of Des Moines City Engineer.

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

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

about 2.5 miles above station. During the water year 1956, the average pumpage was 

about 39 cfs. These galleries are 150 to 300 ft from the river and generally about 

30 ft below grade. At times, water is pumped directly from Raccoon River into recharge basins above galleries. Effluent from city sewage-treatment plant, which includes storm-water runoff from portion of city, enters Des Moines River about 3 miles 

below station, and corresponds roughly to pumpage, except following heavy local rains. 

Net effect of pumpage, storm water, and other diversions is not known. Low flow can 

be regulated by pumpage into or release from reservoir of Des Moines Water Works 

(capacity, 4,800 acre-ft) on Raccoon River.

Cooperation. Gage readings and average monthly pumpage from galleries furnished by Des 

Moines Water Works.

454 ILLINOIS RIVER BASIN 

Chicago Sanitary and Ship Canal at Lockport, 111.

Location.--Lat 41°34'11", long 88°04'42", in SW£ 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 1956 in reports of Geological Survey. January 1900 to December 1936 in 1937 State report entitled "Streamflow data of Illinois,"

Average discharge. 56 years, 6,078 cfs.

Extremes.--Maximum total discharge during year, 19,078 cfs Apr. 29; minimum total, 425 cfs 

Oct. 31.

1900-1956: Maximum total discharge, 24,585 cfs Oct. 10, 1954; minimum total, 91 cfs 

Dec. 15, 1938.

Note. Extremes for 1948-53 water years are figures of total daily discharge, not 

instantaneous.

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

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

by adding the mean daily discharges, based on half-hourly discharge readings at dams, 

sluice gates, lockages, exciter turbines in operation and main turbines in operation as 

corrected for variable efficiencies, and the leakage of lock gates, dams, sluice gates, 

and turbines not in operation.

Chicago pumpage includes water from Lake Michigan to supply Chicago metropolitan 

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

municipalities served by Chicago, and an average of about 186 cfs from agencies not 

served by Chicago.

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

and inflow from Des Plaines River basin.

The Federal permit of June 26, 1930, issued by Secretary of War, limits the diversion 

of water from Lake Michigan to an annual average of 1,500 cfs, exclusive of pumpage for 

municipal supplies.

Cooperation. Records furnished by The Metropolitan Sanitary District of Greater Chicago.

Rev is ions (water years). WSP 955: 1940-41(m) . WSP 1005: 1943. WSP 1175: 1945.

Records available. May 1943 to September 1956.

Gage. Water-stage recorder. Datum of gage is 450.39 ft above mean sea level, datum of 

T929 (Corps of Engineers benchmark). Prior to July 31, 1945, wire-weight gage at site 

400 ft downstream at same datum. July 31, 1945, to Sept. 2, 1948, wire-weight gage at 

site 30 ft downstream at same datum.

Average discharge. 13 years, 40.4 cfs.

Extremes. Maximum discharge during year, 2,020 cfs Aug. 13 (gage height, 1.88 ft); no 

flow part of each day Oct. 12 and July 1.

1943-56: Maximum discharge, 22,000 cfs Apr. 29, 1947 (gage height, 15.00 ft), from 

rating curve extended above 4,200 cfs on basis of velocity-area studies and slope-area 

determination of peak flow; no flow for many days in most years.

A stage of about 15.1 ft occurred in 1927, from information by Corps of Engineers.

Remarks. Records poor.

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

531 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 sq mi), and return flow from water diverted from lake 

for use at pumping plant and not otherwise measured. The last three items were not ineluded 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. Rainfall record (mean of 

three gages within basin) furnished by State Water Survey.

558 RECORDS AVAILABLE ON LAKES IN INDIANA

For several years records of the water-surface elevation of many of the lakes in Indiana have been collected by the Geological Survey under cooperative agreement with the 

Indiana Department of Conservation, Division of Water Resources. These records have not 

been published but are available in the files of the district office of the Geological 

Survey in Indianapolis, Ind. In general, the records are based on once-daily reading of 

a staff gage by a local observer and consist of daily, monthly, and yearly mean watersurface elevations as well as graphs showing the fluctuation in elevation. Discharge 

measurements, made at the outflow, are also available in some instances.

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

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

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

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

DISCHARGE MEASUREMENTS AT POINTS OTHER THAN GAGING STATIONS 559

Measurements of streamflow in the Hudson Bay and upper Mississippi River basins made 

at points other than regular gaging stations are given in the following table. Most of 

these measurements were made during periods of base flow when streamflow is primarily 

from ground-water storage. Measurements believed to have been made under base-flow 

conditions are identified by an asterisk (*) to the left of the discharge figure. These 

measurements when correlated with the simultaneous discharge of a nearby stream where 

continuous records are available will give a picture of the low-flow potentiality of 

stream. The column headed, "Measured previously" shows the water years fop which measurements were made at the same, or practically the same, site.

Determinations of peak flow at points other than regular gaging stations are given in 

a separate table on page 566.
