History & Status of the Fishery
The fishery is evaluated via biennial major surveys and annual species-specific surveys. Attempts to introduce aquatic vegetation have generally failed. Bass spawning habitat has been installed at various locations and other habitat enhancement projects are planned. Heidecke Lake receives annual stockings of walleye and hybrid striped bass. Pure muskellunge are stocked every third year, while black crappie and largemouth bass are released based upon availability. A special mercury advisory is in effect for smallmouth bass 18" and larger which limits consumption to one meal per week for the most sensitive populations.

Heidecke Lake is maintained by periodically pumping water from the Illinois River. As a result, the lake supports a variety of fish species in addition to those listed above, including common carp, quillback, freshwater drum and others. Heidecke Lake is supported by a thriving gizzard shad forage base as well as various other minnow species. Round gobies have been recently discovered as well.

2007 was a good year for a few fish each trip, mainly walleye and white bass with an occasional striper when trolling. Had some good crappie action with minnows and tube jigs 18 inches below floats, not to mention a number of 5-7 lb. cats on the same rig. as you can imagine the crappies slowly take the jig down whereas the cats will take the float and the rod if not careful. Would really like to get out on Heidecke ice fishing, could be the best walleye fishing in all of Illinois. Hope the water level stays low so I can get my boat to the far side, under most conditions even a light breeze can make the bridge a dangerous, head crushing experience. getnany
