From 1910 to 1958, the former bottomland lake and marsh were leveed and drained for farming.[1]
From the late 1880s to the mid-1980s, approximately 90% of the site was strip-mined for coal.[2][3][4]
The Illinois Department of Natural Resources purchased the land in the 1980s.[5] The Illinois Department of Natural Resources partnered with the U.S. Army Corps of Engineers on a reclamation project that was completed in May 2003. The project optimized the habitat for wildlife (fish and waterfowl), improved flood control, and increased food and cover for wildlife.[6]
The three major lakes are Johnson (600 acres (240 ha)), Wheel (350 acres (140 ha)), and Shovel (100 acres (40 ha)). There are over 200 lakes at Banner Marsh.[4]

The park borders the Illinois River and contains over 200 water bodies that serve as a freshwater marsh habitat for wildlife. The land contains scattered deep-water lakes, floodplain forests, levees, shallow marshes, and extensive grasslands.[7]
