Heidecke State Fish and Wildlife Area is located just west of I-55 and south of the Illinois River on Pine Bluff/Lorenzo Road.

This is a perched lake which is used as cooling for the Collins Station Power Plant. It is set in such a way to maximize wind in the Illinois River Valley, which makes it unsafe for non-powered boats.

For more information, you can contact the State Park at 1-815-942-6352.
