Henry's Fork

To find best action on the lower river, try streamers in waters not in direct sunlight, especially early & late in the day. Streamers will also produce in Box Canyon. On the lower river, midge and BWO emergences are best during low light conditions. Much of the river above Riverside Campground closes the end of the month. Check IDF&G fishing regulations.
Fly Patterns to use:
Brook’s Sprout-Baetis
Egan’s Silver Bullet-Baetis
Antonio’s Adult BWO
