The 957 acre natural lake has no motor size restrictions and is a boating or fishing enthusiast's dream. Three boat ramps are located on the lake. Angling is a popular pursuit at Black Hawk Lake. Channel catfish, crappies, walleyes, bluegills, sunfish and largemouth bass provide a challenge to anglers of all ages. The Marina and North Shore areas are located on the northeast corner of Black Hawk Lake. Black Hawk has a universally accessible fishing pier, and approximately 50 percent of the lake shore offers public access. There is a fish cleaning station at the Ice House Point boat ramp. A non-supervised swimming beach is located at the east end of the campground. There is also an unsupervised swimming opportunity at Denison Beach along the North Shore of the lake..
