Description: Coffeen Lake is under a management agreement between The Illinois Department of Natural Resources, and AmerenUE for outdoor recreation and conservation purposes. The lake is a cooling facility for Ameren's coal-fired power station. There are two concrete boat ramps, with one at the far north end of the lake, and the main ramp near the site office. There is no concession stand on the site, but gear can be acquired at a private business just west of the site office.

History and Status of the Sport Fishery: Approximately 20 species have been collected on this water body. Coffeen Lake now receives periodic stockings of Black Crappie, and the pure Striped Bass stockings have been discontinued due to an increase in water temperatures.

Additional Lake Information: Coffeen Lake has a 25 hp out-board motor limit.
