About Bois Brule River

The Bois Brule River in Douglas County is the most storied trout and steelhead river in northern Wisconsin — fished by five U.S. presidents and home to wild brook trout, brown trout, and a strong run of Lake-run rainbow trout (steelhead) and lake-run brown trout from Lake Superior. Cold, dark, spring-fed water flows through Brule River State Forest. Complex regulations — multiple seasonal closures protect spawning fish and specific sections.
