Heidecke Lake

Heidecke Lake was originally created to act as a power plant cooling lake by Midwest Generation Company. The power station has since shut down and changed fishing on the lake drastically. Historically, fishing was driven by currents resulting from power generation. Now, the best bite occurs when the wind is blowing. Fishing is excellent in the spring and drastically slows when the shad hatch occurs, typically when water temperatures reach around 78 degrees. The lake offers a diverse fishery. Black bass, temperate bass, catfish and walleye all provide excellent action. Smallmouth bass are the dominant black bass species. Heidecke has the potential to produce record hybrid striped bass. The lake is open for fishing from April 1st to ten days prior to the opening of waterfowl season in the north zone (this date varies annually). Water skiing, wading, swimming and sail boating are prohibited on the lake, adding to its appeal to anglers. The boat access is open daily from 6:00 a.m. to sunset. The bank fishing access on the center and eastern dikes opens at 6:30 and closes at sunset. During windy conditions, the site superintendent can close the lake to all fishing. Outboard motors are required with no size restrictions, however a 40 mph speed limit is in effect. Since dangerous conditions can be created by the wind, boats over 14 feet are recommended. There are no-wake areas near the boat landing and under the center dike bridge. Zebra mussels have been accidentally introduced into the lake. As a result, special precautions are required when leaving the lake to ensure the further spread of this invasive species. Make sure you check with posted regulations at the access. Special length and creel limits exist for walleye, largemouth bass, smallmouth bass, white bass, stripers and hybrid striped bass.

Gizzard shad are the primary forage for the larger predators. Crayfish, juvenile panfish, drum and a variety of minnow species also contribute.
