Boating and Fishing
Anglers will find ample supplies of crappie, bass, bluegill, catfish, carp, bullheads, and many other species in the Illinois River. A boat ramp is available for visitors' boats. Although there is no motor limit on the Illinois River, boaters should be aware of the danger of barge traffic and the close proximity of the Marseilles Lock and Dam.
