Henry's Fork

Flow through Box Canyon is reduced to about 780 cfs. Try dead drifting streamer patterns during low light conditions, or hopper patterns along bank side water. River in Last Chance-Harriman reach has very technical daytime fishing. Plenty of weeds makes indicator fishing a good choice.  Be sure to have ant, beetle and hopper patterns in that fly box. Below Warm River confluence, river is tough fishing all the way to Chester Dam. 15000 cfs is flow below Ashton Dam. There are early AM spinner falls, and good caddis activity during evenings. Very early or late in the day offers some improvement to this condition. These conditions are unlikely to change much until September.
