Henry's Fork

Seems like what is going on for fishing the South Fork applies to the lower Henry's Fork. Afternoon BWO activity, caddis later in the afternoon, and mostly presenting streamers to migrating browns. BWO activity rules the roost at the Last Chance-Harriman stretch, while streamer fishing in Box Canyon and The Tubs is the order of the day. If you plan on fishing the upper river, watch the weather.
Fly Patterns to use:
Brook’s Sprout-Baetis
Egan’s Silver Bullet-Baetis
Antonio’s Adult BWO
