Warm water closures remain in place for the Madison, Firehole, and Gibbon. The northeast corner is still the star, with the Yellowstone, Lamar, and Slough Creek all fishing great. Hoppers and ants are bringing fish up consistently, especially on calm afternoons. Mayflies and caddis are still in the mix, so be ready to switch if trout get picky. Target meadow sections and riffles where fish are cruising for terrestrials.
