The Yellowstone is fishing great even with the high summer temperatures. We’re starting to see the first hopper grabs but its not quite there. The Stoneflies are done and the hopper fishing is just getting going but we expect that to change soon. Right now our best fishing has been drifting streamers under an indicator with a small nymph behind it. Using some downstream mends and twitches to keep the streamer swimming with some drag on it. Big browns fall victim to this tactic regularly being the carnivores they are. Rabbit sculpins in natural and olive with a #16-20 beadhead nymph running 15” behind has been the hot ticket. Soft hackles are a great nymph patterns along with pheasant tails and caddis.
