About Ausable River (East Branch)

Classic Adirondack freestone water flowing out of the High Peaks through Keene Valley to Au Sable Forks. Wild brook, brown, and rainbow trout in a spectacular mountain setting. Hatches run two to three weeks earlier here than in the Catskills, so April Hendricksons and May Green Drakes arrive ahead of schedule.
