Likely the most reliable location for action on the river these days is the Warm River to Ashton stretch. Hoppers with a small bead head nymph dropper produce during daytime. So does a two nymph rig of rubber legs trailed by your favorite bead head nymph (size 12-16). Try streamers in the evening to interest those big browns. Caddis life cycle patterns will interest the smaller fish. Until we cool off forget the river below Ashton Dam where water is warm enough for swimming. On the upper river consider walking downstream from Riverside Campground to present hopper and caddis life cycle patterns during the evening. Concentrate your fishing efforts early to mid mornings on the Harriman State Park stretch were spinners will be interesting trout.
