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.
Regulations
Complex Bois Brule regulations — night fishing prohibited; Box Car Hole closed July 15–October 31; Mays Ledges closed September 1–May 31; 26" minimum size on rainbow trout, 1-fish kept limit; catch-and-release recommended the rest of the year. Wisconsin Fishing License required ($20 resident + $10 trout/salmon stamp = $30). Verify all Brule River seasonal-closure section boundaries in current Wisconsin DNR trout regulations before fishing.
