Henry's Fork

Although some midges and some BWOs are on the surface, presenting nymph patterns in the lower river above Chester seems the most productive approach lately. Streamers also bring responses from trout, especially under low light conditions. Look for Fall River, with flow at Yellowstone canal diversion more than double normal, to increase flows significantly and add discolor to the river below Chester.
Fly Patterns to use:
Brook’s Sprout-Baetis
Egan’s Silver Bullet-Baetis
Antonio’s Adult BWO
