Detailed Report

The Fork has settled into its autumn groove. Cooler nights push trout deep in the morning, but as the sun rises, fish spread into riffles and shelf lines. Browns are staging and show more aggression daily. Start heavy with a two-fly nymph rig early, then shift to dry-droppers or small dries midday. Evenings are for streamers—cutbanks and shadowed edges can produce explosive takes.

Pro Tips
