With no killing frosts yet, terrestrial insect patterns are great choices for all our small streams. Never overlook a cinnamon ant pattern this time of the season. Flavs are providing action on Big Elk Creek and Palisades Creek. With shorter days and less time for water staying at best temperatures for these mayflies to emerge, expect action to take place for fewer afternoon hours. On other streams BWOs and/or tricos provide great action. Warm River, Birch Creek, Teton River, Robinson Creek, and Little Lost River drainage streams are some. But keep those terrestrial and attractor patterns handy on all of these! Flow out of Blackfoot River Dam has jumped from around 250 cfs to around 600 cfs, so fishing is slow on the river below.
