Migrating browns make for the best streamer fishing here. Best walk-in locations on the Madison River are between from Raynolds Bridge downstream, between Quake and Hebgen lakes, and in the river above Hebgen Lake to the Yellowstone Park boundary. Browns are migrating to spawning areas in the Beaverhead River. Float fishing is the best way to encounter these in the river below Clark Canyon Dam. Wait a few weeks for the peak of brown trout migration into the South Fork of the Madison River.
