2024 Map of Clear Lake

About this map

The Sangamon River and its intricate network of sloughs and lakes dominate this Illinois landscape at the junctions of Cass, Mason, and Schuyler counties. The river's historical path is evidenced by features like McKay Flats and Cuba Island, while smaller waterways such as Little Sangamon River and Bach Slough create a complex wetland environment. In the south, the terrain rises into the bluffs, where Warrior Hill Rd and Kurman Hill Rd wind through the elevated relief overlooking the floodplains.
