“The spring rains and recent storms have pushed the water level above 508’. More precipitation has been called for in the 7-10 day forecast, and we are confident the water levels will remain above 508’ for a significant period of time to allow watercraft access. Boaters must exercise caution while launching the boats and navigating the waterway, as shallow areas persist throughout the lake. IDNR will monitor the lake levels and will close the lake to watercraft if the level falls below 508’, after providing 24 hours' notice to the public.”

Things to do

Trails

Trails

Hikers have many options. The Tallgrass Nature Trail winds through the prairie and its marshes. Depending on the route, Prairie View Trail can be 1 or 3.5 miles long. Self-guiding trail maps are available.

Cross-country skiers enjoy Goose Lake Prairie in the winter. The Visitor Center, which serves as a warming area, offers trail maps.

Boating and paddling

Boating

Only boats for fishing or waterfowl hunting are allowed on the lake. Each must have a gasoline-powered motor as its main propulsion unit. There is no charge for launching. Water skiing, swimming, wading, sailboating, or personal watercraft is not allowed.

Heidecke Lake Closing Policy: If wind speeds are forecast to be 25 mph or above at any time during the day, Heidecke Lake access to boat fishing will be closed. Bank fishing will still be available at the Heidecke Lake Bank Fishing Area off E. Collins Rd. Wind speeds are checked daily by using the NOAA wind forecast at the Morris Muni-James R Washburn Field Airport.

Fishing Fact Sheet

Because of a comprehensive fish-stocking program, Heidecke Lake has good fish populations producing trophy-size bass. Only pole-and-line fishing is permitted, with each angler limited to using two poles. There are no fishing fees, but each angler must have a valid Illinois fishing license unless exempted by law.

To avoid the possibility of overharvest and to assure a good fishery, DNR's Fisheries Division has established minimum length and daily catch limits at the lake. Strict adherence to size and catch limits will result in Heidecke Lake providing a quality fishing experience now and in the future.

Fish are measured while positioned flat on a ruler from the tip of the mouth when closed to the tip of the tail when compressed. All sub-legal-size fish must be immediately released to maximize their chance for survival.

Catch-and-release fishing is encouraged for anglers who catch legal-size fish but don't want to keep them. Anglers should handle fish with care and release them immediately after catching so the fish can survive to later provide other anglers similar recreation.

The fishing season at Heidecke Lake opens on or about April 1 each year and closes prior to the waterfowl season. Call the park at (815) 942-6352 for dates.

Bank fishing access is open from 6:30 a.m. to sunset. The boating access area is open from 6 a.m. to sunset. Both areas are open seven days a week.

A state fishing license is usually required.
