Wisconsin River History
14,000 years ago Glacial Lake Wisconsin stretched over 1,800 square miles and was up to 150' deep. The Juneau County heritage and adventure began after its enormous natural dam of rock, earth and sand burst. The runoff, after approximately three days of draining, created a new course for the Wisconsin River. While traveling throughout the central and northern part of Juneau County, the scenic bluffs you encounter are actually the tops of islands that were in Lake Wisconsin.
The Wisconsin River begins at the Michigan border. It flows south across the glacial plain of central Wisconsin and then, as it flows toward Juneau County, encounters the terminal moraine formed during a previous ice age. As it leaves Juneau County it forms the Dells of the Wisconsin River. Jogging east, then west, kit flows through Wisconsin's hilly Western Upland and finally joins the Mississippi. The river is approximately 430 miles long and is the State’s longest river.

Early inhabitants used the Wisconsin River as a source of transportation. This allowed the inhabitants and some of the first explorers to seek out the regions bounties. The Wisconsin, Lemonweir, Yellow and Baraboo rivers were used to harvest and transport numerous and abundant natural resources. Early settlements popped up along the rivers and began the harvesting of wild rice, buffalo, deer, moose and many species of wild game. The sawmills harvested pine timber that covered the county. The Wisconsin River was the express highway for floating barges of timber and other goods downstream. Over time the continual harvesting and lack of conservation practices exhausted these natural resources.
Today the Wisconsin River is the hardest working river in the nation. Two dams, constructed on the Wisconsin River in the early 1950's were instrumental in the creation of the 2nd and 4th largest inland lakes in Wisconsin: Castle Rock and Petenwell Lakes.

The river is fed by dozens of smaller rivers and streams and becomes increasingly larger by the time it reaches northern Juneau County. This section of the river is already part of Petenwell Lake. As the river flows downstream the waters flow through the Petenwell Dam on its way to Castle Rock Lake. Between the Castle Rock Dam and the Wisconsin Dells you will encounter a calm free flowing stretch of the Wisconsin River. However, when conditions favor heavy storms or the river is at or near flood stage it can become a very powerful and dangerous river.
The Wisconsin River, or the "big river" as it is also known, was recorded in 1673 by Jacques Marquette as "Meskousing". The original name is truly obscure. Explorer Louis Joliet renamed the river "Miskonsing" in l674. The first published book of the first recorded voyage on the Wisconsin River was authored by Melchisedec Thevenot in 1681. French explorers later modified the name to "Ouisconsin". That name appears in 1718 on a map in Paris. Before Wisconsin was a territory in the early 19th century the name was changed to "Wiskonsan", now "Wisconsin".
