This study will consider development of a countywide water project that would
provide flood control, assure adequate water supplies for existing and new indus-
tries and for municipal use, improve water quality, and meet the demands for
water-associated outdoor recreation. The practical solution appears to be reservoir
storage. The 1960 population of the county is 56,154. The 3 largest communities in
the county are Marquette, Ishpeming, and Negaunee with 1960 populations of
19,824, 8,857, and 6,126, respectively.

The study gives consideration to flood protection for about a 2-mile reach of
industrial and residential area not included in the authorized flood control project
for Winona. The record 1965 flood exceeded the 1952 flood by almost 3 feet, causing
damages in the 2-mile reach outside of the authorized protected area estimated
at $3,700,000. A successful flood fight prevented even greater damages. The most
practical solution appears to be levees, flood walls, and related interior drainage
facilities. The 1960 population of Winona is 24,895.

Irondequoit Creek and triburaries.

Mississippi River, La Crosse

The study gives consideration to flood protection for the city of La Crosse. The
record 1965 flood exceeded the 1952 flood by about 2.6 feet at La Crosse, causing
damages estimated at $7,600,000. More extensive damages were prevented by tem-
porary diking and sand bagging to protect a North Side residential area from Mis-
sissippi backwater through the Black and La Crosse River channels. The most
practical solution appears to be an extensive system of levees and flood walls and
related interior drainage facilities. In 1960, La Crosse had a population of 47,575.
Mississippi River, Prairie du Chien

The study gives consideration to flood protection for the city of Prairie du Chien.
The record 1965 flood exceeded the 1952 flood by over 4 feet at Prairie du Chien and
caused damages estimated at $2,500,000. The most practical solution appears to be
local protection by means of levees and floodwalls with related interior drainage
facilities. In 1960, the population of Prairie du Chien was 5,649.
St. Croix River, Wis. and Minn.

The study gives consideration to flood control for downstream communities.
The record 1965 flood exceeded the 1952 flood by about 4.4 feet at Stillwater, Minn.,
causing damages estimated at $5,500,000 at and downstream of Stillwater. St.
Croix River discharges contributed significantly to the record high stages on the
upper Mississippi River. Reservoir storage appears to be the most practical solu-
tion. Reservoir storage could provide benefits for flood control, water supply, water
quality control, recreation and fish and wildlife. If reservoir storage is not feasible,
local protection works for Stillwater, and possibly for other, affected communities,
will be considered. The 1960 basin population is estimated at 150,000. The largest
communities and their 1960 populations are Stillwater, 8,310 and Bayport, 3,205,
in Minnesota, and Hudson, 4,325, in Wisconsin.
