Heidecke Lake State Fish and Wildlife Area, Wildlife refuge and state park in Grundy County, United States.
Heidecke Lake State Fish and Wildlife Area is a protected reserve spanning roughly 1,300 acres with rocky shorelines, breakwaters, and multiple fishing locations. The water is regularly stocked with various fish species to support healthy population management.
The area began in 1978 as a cooling pond for the Collins Generating Station before being converted into a fish and wildlife conservation area. This transformation allowed an industrial site to become a space for wildlife protection and outdoor recreation.
The area draws local anglers and nature enthusiasts who gather to fish and share their outdoor interests. The open water attracts people seeking to spend time outdoors and connect with the natural environment.
Daily access is available from April through fall, with a concrete boat ramp, parking areas, and a fishing pier on the eastern shore. Visitors should note that availability can vary with the season and weather conditions.
The water hosts several prized fish species including Walleye, Hybrid Striped Bass, and Muskellunge, maintained through regular stocking efforts. These targeted programs make it a noteworthy destination for anglers seeking these specialized species.
