Smaller streams are now mostly at base level. That means concentrate fishing efforts on deepest downstream water. Terrestrial insect patterns will be effective, even for days after a killing frost. In the smaller category Bear, Birch, Palisades, and Big Elk Creeks currently offer the best fishing. Larger small streams offering good fishing are the Teton River throughout, lower Blackfoot River (still a bit high with nymphing and presenting streamers best ways to find action), and Warm River (BWO, hopper, and caddis activity).
