🏆🏆🏆🏆 I&M Canal Lock — Historic Illinois & Michigan Canal lock town — where the canal meets the Illinois River
Marseilles State Fish and Wildlife Area is located near the historic I&M Canal town of Marseilles — where the Illinois & Michigan Canal meets the Illinois River. Marseilles was a critical junction point on the canal, and the town’s dam powered mills that processed grain from the surrounding prairie. The Illinois River at Marseilles was historically one of the most productive freshwater fisheries in the world — commercial fishermen harvested millions of pounds of fish annually in the early 1900s before pollution and sedimentation degraded the river.

Frequently Asked Questions
Why was the I&M Canal important?
The Illinois & Michigan Canal (1848) connected Lake Michigan at Chicago to the Illinois River — creating a continuous water route from the Atlantic Ocean to the Gulf of Mexico. This waterway transformed Chicago from a small frontier town into a transportation hub and eventually America’s second-largest city.
Wildlife & Nature
The Marseilles area provides access to the Illinois River corridor — one of the most historically important waterways in the United States. The Illinois River connected the Great Lakes to the Mississippi, serving as a trade route for thousands of years before Europeans arrived. Marquette and Jolliet traveled the river in 1673, and the Illinois and Michigan Canal (1848) made Chicago a commercial powerhouse. The river’s backwater lakes and sloughs support massive populations of migrating waterfowl — the Illinois River valley historically supported the largest concentration of wintering waterfowl in the interior United States. Bald eagles fish from riverside trees. Channel catfish, sauger, and freshwater drum are caught from the banks.
