🏆 Illinois River Backwater — Backwater wetland on the Illinois River — managed for waterfowl habitat and flood control
Devils Island Wildlife Management Area protects backwater wetlands along the Illinois River — part of the vast Illinois River floodplain system that once supported enormous waterfowl populations. The Illinois River valley was historically one of the most productive waterfowl habitats in North America, with fall duck migrations numbering in the millions. Drainage and levee construction destroyed 90% of the original floodplain wetlands, making remaining sites like Devils Island critical for migrating and wintering waterfowl.
