The Brule River is a 52.3-mile long river with most of the river serving as the border between Wisconsin and Michigan. It has been a solid trout fishery for years as anglers target brook trout and brown trout from the many access points along the river. As you get closer to the Brule River Flowage, anglers do also report good fishing for smallmouth bass as well. In smaller numbers, anglers can also target a variety of other fish such as muskie, largemouth bass, walleye and a variety of panfish.
