The Henry’s Fork is fishing very well. It is a morning and evening game. It just gets too hot in the afternoons. The river fishes best upstream from the Ashton Dam. The lower river downstream of the Ashton Dam is affected by irrigation demands. Harriman Park is fishing well in the morning and evening with PMD’s, Flavs, and caddis. Try a spent wing spinner or nohackle for both mayflies. Don’t be afraid to try a beetle or ant pattern. The Box Canyon is running a lot of water, but the nymph fishing has been good. Try Quill Nymphs, Zebras, and small Pheasant Tails. There are still quite a few golden stones flying around, so it is worth throwing a dry golden at times. You can also tie into some nice fish just before dark on streamers! The river between the Riverside Campground and Ashton has been good just fishing a dry dropper setup, with a chubby and bead in the pockets.
