Yellowstone Park
Streams here are still impacted by the recent big rains. Best exception is the Firehole River where water is a bit high. Caddis, BWO, PMD and yellow sally life cycle patterns are making for action. Duck Creek also offers some action with damselfly nymph patterns and streamers being best bets.
