PMD's on the upper portneuf have been fishing really well! Also, green drakes on the henry's fork, Sallies on the Blackfoot, and tons of caddis mixed into all those bags!
Most of the small streamers are experiencing a lot of run off right now, but the island park area has been seeing some great fishing! Lucky dog creek and moose creek have been producing a lot of brookies with some bigger fish showing their faces! Small dries and a good assortment of your favorite nymphs should get em good!
