In order to improve the smallmouth bass fishery, the State Hatchery System stocked smallmouth bass in Clinton Lake from 2001 to 2012. The highest catch rate for smallmouth bass was obtained in the 2009 survey. The majority of the smallmouth bass were less than 6 inches, but this relates to a strong year class and will provide excellent smallmouth fishing in a few years.

Fair to Good: Anglers have been getting some bites on chartreuse colored jigs as fish move up into shallower water levels.

Location: Clinton Lake is located in DeWitt County 10 miles east of Clinton, IL.

Description: This 4,895 acre lake was constructed to serve as a cooling reservoir for the Clinton Nuclear Power Station. The lake has a maximum depth of 60 feet and an average depth of 15 feet. Clinton Lake is No Wake for all boats from 1/2 hour after sunset to 1/2 hour before sunrise with the exception of waterfowl hunters. Various portions of the lake are designated as no-wake, electric motor only, or no boat areas for safety and security reasons. All IDNR ramps are now equipped with wheelchair accessible boat docks. There are 17 Class AA campsites, 286 Class A campsites and 5 Class B/S campsites at Clinton Lake with showers and almost all are adaptable to either tents, trailers or motor homes. Bowfishing is allowed on certain areas of the lake.

History and Status of the Sport Fishery: The fish population in Lake Decatur is intensively surveyed every two years. The fish are measured, weighed, and scales collected before releasing them alive. Hybrid striped bass and walleye populations are surveyed annually and are maintained by annual stockings through IDNR hatcheries.

In addition to the species listed above, buffalo, redhorse suckers, and carpsuckers are common, but few are caught by anglers. Yellow bass, longear sunfish, green sunfish, orangespotted sunfish, and yellow bullheads are common, but are seldom harvested by fishermen due to the small size attained by these species. Smallmouth bass, rock bass, and redear sunfish are occasionally collected, but likely very rare in the angler's catch.

Additional Lake Information: Bowfishing is allowed on certain areas of the lake. The fish cleaning station at Weldon Access area has been permanently closed due to damage from vandalism. The North Fork fish cleaning station is temporarily closed for repairs, however the Mascoutin (main park) fish cleaning station is open for use.
