Wisconsin Musky Lakes

766 musky fishing waters in Wisconsin. Wisconsin has one of the most intensively managed musky fisheries in North America. The Wisconsin DNR classifies musky lakes into four tiers—A1 (trophy waters), A2 (consistent action), B (good fishing), and C (limited fishery)—and actively monitors population health across hundreds of designated lakes. Musky waters range from the glacial Northwoods lakes of Vilas and Oneida counties to flowages, river systems, and reservoirs across the state.
