We’ve been having quite a bit of success on the entire river from the Dam down to Menan. We’ve been seeing PMD’s, Caddis, Golden Stones, Pink Alberts, Hoppers, Ants, and Beetles. Pretty much everything in your fly box.
It’s been a little quiet on the Henrys Fork. In Island Park: Terrestrials, PMD’s (a few), & Caddis (a few). Around Warm River you’ll use a Hopper / Dropper combo. Big Foam flies & a big selection of nymphs.
PMD’s are the ticket here along with Hoppers and other terrestrials. You can also use Caddis in the evening. It’s a little bit grassy around Fox Creek. If you’re using a hopper / dropper combo make sure and use a bead head pheasant tail. Using a copper john or something similar might target whitefish… Another Teton River tip is if it’s overcast, typically, it will be better fishing.
