The Rock River in Illinois supports more than 53 fish species,including gravel chub and lake sturgeon, northern pike, muskie, smallmouth bass, walleye and sauger.

Mussels are abundant in the Rock River, and their shells were sold to the button industry before plastics became widespread after World War II.

Other wildlife to view are frogs, turtles, ducks, wading birds, muskrats, foxes and beavers. Visitors may see kingfishers and bald eagles fishing, and hear some of the 100-plus species of songbirds.
