Heidecke Lake Reopens After Low Water Delay, But Boaters Still Need to Use Their Heads

Heidecke Lake is reopening to boaters in time for Illinois Free Fishing Days, and that is good news for anglers who have been waiting on water instead of fish.

The Illinois Department of Natural Resources is reopening Heidecke Lake in Grundy County to boaters on Friday, June 19. The lake normally opens April 1, but drought-driven low water pushed that back this spring. Heidecke is a former power plant cooling lake near Morris, and IDNR leases the site for public outdoor recreation.

The delay was not about red tape for the sake of red tape. Water levels dropped too low for safe navigation by boats and for first responders who might have to make a rescue on the lake. IDNR says ideal water level is about 510 feet, and safe navigation is typically possible at 508 feet or higher. The lake reached 508 feet on June 18, which cleared the way for reopening.

That does not mean everybody should run it wide open like nothing happened. IDNR is warning that shallow areas still persist throughout the lake. Boaters need to use caution launching, running, and fishing. Normal lake rules still apply, and common sense should too. Low water can turn familiar structure, hazards, and shorelines into a different animal.

Public access matters. A reopened lake means anglers get opportunity back, families get a place to fish during Free Fishing Days, and the local outdoor economy gets a little more traffic. But access only works when safety is part of the deal. Nobody wants a rescue call because somebody treated a recently reopened, drought-stressed lake like a summer playground with no consequences.

Go fish it. Enjoy the open water. Just run smart, watch your depth, and remember that good fishing access is worth taking care of.
