Henry's Lake

Best fishing appears to be on east side creek mouths with Targhee Creek outlet leading the pack. Just look for concentration of boats. Mity mite, Henry's Lake renegade and California leech are good candidate patterns. Damselfly hatch is ongoing, but a bit spotty. Try west side as well as east side, and look for channels between weed beds.
Fly Patterns to use:
Mini Damsel Nymph
Rohmer’s BH Simi Seal Leech Canadian Brown
Chan’s Chironomid Pupa Black/Red
