Yellowstone Park

The Firehole River is warming. Some of the best fishing in the Park can be enjoyed in the upper Lewis River drainage where getting out onto water of Lewis and Shoshone Lakes to locate weed beds will bring on action from leech patterns presented on full-sink lines. The meadow section of Lewis River between the two lakes still provides the fastest fishing around for brown trout chasing streamer patterns.
Fly Patterns to use:
Egan’s Silver Bullet-Baetis
Palomino Caddis Tan
