Calhoun Point Fish and Wildlife Management Area is located in Calhoun County, Illinois, at the confluence of the Illinois and Mississippi Rivers. The project area is bound by the right descending bank of the Illinois River, extending from river mile 2.2 to 3.25, and the left descending bank of the Mississippi River, extending from river mile 219 to 223, Navigation pool 26. The 2,157 acre project area is federally owned and managed by the Illinois Department of Natural Resources under a cooperative agreement through the US Fish and Wildlife Service. It is a prime site for migrating waterfowl and a prime feeding area for herons from two nearby rookeries. Sedimentation since 1938 has resulted in the reduction of the water surface acreage from 600 acres to 450 acres. Sedimentation has severely impacted deep water habitat. This management area is a prime site for migrating waterfowl and a prime feeding area for herons from two nearby rookeries.
