Small Streams

Don't rely on very small streams for the rest of the season as they most likely are at base level meaning cold and having reduced overhead cover. Exceptions could be upper Birch, Big Elk, Bitch, and Palisades Creeks. Such as the Blackfoot, Teton, Warm, and Buffalo Rivers will remain good for quite a while thanks to streamers, caddis and late season (BWO) mayfly activity and terrestrial insect presence until a killing frost happens.
Fly Patterns to use:
Harrop’s CDC Water Wasp-Honey
Antonio’s Adult BWO
