Seems like the BWO or streamer theme applies to a lot of places, southwestern Montana included. Browns are migrating in the Madison, Ruby, Beaverhead, Big Hole, Gallatin, Missouri and Yellowstone rivers, so streamers are the choice here. Want to try for REALLY BIG browns? Wade Lake produced the Montana state record (twenty-nine pounds and change) and near record browns. Get those streamers down deep here. Other great still waters for big browns are Clark Canyon Reservoir, Hebgen Lake, Quake Lake, and Smith Lake. If you prefer top water fishing, the BWOs are abundant on nearly all rivers.
