We see that flows out of Island Park Dam have been reduced to around 400 cfs. That makes for tougher boating through Box Canyon, but opens up a lot of wading possibilities. Two nymph rigs during daytime should produce, but streamers presented at the tops of holes and deeper runs, then on through, during low light conditions have a better chance for getting you into some of the big bows the “Box” is famous for hosting.
Fishing is picking up on the river below Ashton Dam. BWO, mahogany dun, and hopper patterns bring daytime action, but streamers under low light conditions will get you into the bigger fish.
