The Bois Brule River is a very good trout stream. It has become a popular river to fish due to the spawning runs for steelhead, brown trout and salmon. Steelhead and salmon move into the river in the fall. Steelhead can be found in the river through the winter and then they head back out into the lake in the spring as waters start to warm. Brown trout are found in the river during the fall and some fish may be found through the winter months as well. Wild brook trout live in the river and can be targeted in the upper section of the river.
