Small Streams

Look for terrestrial insect patterns to be important flies for action on most any small stream until a killing frost comes along. Another consideration is that with shortening days and cooler weather, and absence of AM trico activity, afternoons will be the best time to find action. Also consider that with the uncertainties of a good snowfall this coming winter any tail water fishery (portions of Big Lost, Blackfoot, and Portneuf Rivers) will have low flows for the remainder of the season because of actions to fill depleted reservoirs.
