White sucker, shorthead redhorse, carp, northern pike, walleye, white crappie, and black crappie were sampled at or above local median levels. Black, brown, and yellow bullheads, yellow perch, and bluegill were found at below local median levels. Shorthead redhorse probably entered Charley Lake with water pumped from the Mississippi River. The numbers of carp and black bullhead are significantly lower than in 1979. Walleye are the result of stockings in Pleasant Lake.

Recreational activities such as recreational boating, angling, waterfowl hunting, and diving may spread aquatic invasive species. Some aquatic invasive species can attach to boats, while others can become tangled on propellers, anchor lines, or boat trailers. Many species can survive in bilge water, ballast tanks, and motors or may hide in dirt or sand that clings to nets, buckets, anchors, and waders. Fortunately, completing simple steps can prevent the transport of aquatic invasive species.
