Fishing Regulations in Wisconsin
Size limits, bag limits, and seasons by species in Wisconsin.
Wisconsin's Department of Natural Resources oversees a deep fishery, with muskie, walleye, and bass in the northwoods lakes, Driftless spring-creek trout, and the Great Lakes salmon runs. Many waters carry their own seasons and special regulations, so check the rules for your spot before you keep a fish.
