Henry's Fork
Flow the top of Box Canyon is reduced to about 55 cfs. Flow below the Buffalo River confluence improves it significantly. Try fishing nymph patterns deep ( zebras, princes,etc. ). Streamer patterns in deep holes and runs remain the best way for action.
At Last Chance-Harriman, BWOs and mahogany duns are active during unsettled weather like that coming this week keeping some cautious top water fishing going for now. Warm River to Ashton is best fished with large streamer patterns for migrating brown trout. Below Ashton Dam, the river remains friendly to fly fishers during day time hours. Flow is around 650 cfs above Chester Dam, and about 920 cfs below it. Very early or late in the day or during unsettled weather offers some good chances of successful streamer presentation. The new Fun Farm Bridge will open soon to give convenient access to the river below Chester Dam.
