It is one of the more heavily fished lakes in the state. Many fisherman consider it one of the nation's top walleye fisheries. Other species present include Bluegill, Largemouth bass, Muskellunge, Northern Pike, Perch, Burbot, White bass, Freshwater drum, channel catfish, flathead catfish, and Smallmouth bass.

Lake Winnebago is also very popular for ice fishing. It is not uncommon for 10,000 cars to park on Lake Winnebago during the ice fishing season. Expansion cracks on the ice are bridged.
