Description: Prior to 1947 Wolf Lake was a small, shallow glacial lake situated in a wetland area between the confluence of the Grand Calumet and Calumet Rivers. Since that time however, the construction of a low level dam and levees from extensive dredging operations have changed the lake's appearance. The lake and it's fishery have developed into a haven for anglers to enjoy some quiet time away from the highly urbanized vicinity and catch quality-sized fish. The lake is located on the Illinois and Indiana state line. The Illinois portion of Wolf Lake consists of 390 of the acres of water and is managed by the Illinois Department of Natural Resources. Fishing ranks as one of the most popular recreational activities at William Powers. The maximum depth of Wolf Lake is 15 feet and the average depth is 5 feet. There are 3 developed boat ramps in the Park, but no concession or fish cleaning facilities available.
