Henry's Fork
Flow through Box Canyon remains about 350 cfs. That low is rough on hard sided boat bottoms but great for wading. Dead drifting streamer patterns and nymphing with bead head and rubber leg patterns produce action although some discolor is present coming in from the reservoir above. Recent cold weather should help in getting mahogany duns going, and BWOs are becoming common afternoons along the Last Chance-Harriman section.
Warm River to Ashton Reservoir is cooling and is seeing brown trout beginning to run through to upstream spawning areas. River below Ashton Dam is flowing at around 1000 cfs and is offering much improved fishing. Terrestrial insect patterns presented close to vegetated banks during warm, sunny weather produce. BWO life cycle patterns produce during afternoons, especially during unsettled weather. Streamer patterns presented under low light conditions will take over as the best way to encounter larger brown and rainbow trout.
