Wisconsin River

View Exhibit map

The Wisconsin River is part of an historic water transportation route, first used by Native Americans and later by the French missionaries and fur traders. In the 1840's, a canal, later taken over by the Federal Government, was built connecting the Lower Wisconsin River to the upper reaches of the Fox River, providing a navigation link between the Mississippi River and the Great Lakes. The Upper Wisconsin River was never navigable, but was used extensively for log drives by the lumber industry.

While the Fox River was used by commercial vessels, the sandbar-choked Lower Wisconsin River was never successfully developed for navigation. Two navigation locks (Portage and Prairie du Sac) and several swing bridges remain on the Lower Wisconsin River as reminders of this period.
