Henrys Fork of the Snake River, Box Canyon to Riverside

Cooler water flowing from Island Park Reservoir is keeping fish aggressive throughout the water column on nymphs and streamers. Big rainbows are cruising as temperatures drop, creating solid sight-fishing opportunities from Box Canyon through Riverside. At 985 CFS, flows are stable and manageable. Mahogany Duns are just beginning to emerge, so expect dry action to improve over the next few days as the hatch develops.
