At the Kaskaskia Navigation Project, the U.S. Army Corps of Engineers in cooperation with the Illinois Department of Natural Resources provide stocking and habitat improvement programs to increase fish populations and provide a diversity of species.
Fishing on the Kaskaskia River offers year-round varieties of fish such as white bass, bluegill, crappie, channel catfish, largemouth bass, freshwater drum, carp, flathead catfish, and sauger.
As part of the wildlife management program, food plots of sunflowers, corn, millet, clover, brasicas and wheat are planted each spring at several locations along the Kaskaskia River. More than 450 acres of public lands are open to hunting and subject to state regulations which can be found at the Illinois Department of Natural Resources
website. Wildlife management areas can be found all along the river with parking lots which provide access. The Kaskaskia River is also a mid-migrational resting area for waterfowl and other migratory birds, thus a variety of wildlife can be seen throughout the year. Subimpoundments near the Jerry F. Costello Lock and Dam (formerly the Kaskaskia Lock and Dam), and around Baldwin State Park are intensively managed for waterfowl. These areas are part of the Kaskaskia River Wildlife Management Area.
Hunting is permitted on all public land except where posted and within 100 yards of developed recreation areas or residences.

Wildlife management areas can be found along the Kaskaskia River with parking lots providing access. In addition, the Kaskaskia River is a mid-migrational resting area for waterfowl and other migratory birds, providing another opportunity for visitors to spot wildlife.
