The recreation area features three campgrounds with 205 campsites, modern cabins, and amenities including fish cleaning stations, dump stations, and showers, making it a comprehensive hub for boating and fishing activities.

Day-use areas remain open year-round, though campgrounds 1 and 2 close seasonally (Nov. 15 through late March) for bald eagle winter roosting.
