Below Flaming Gorge Dam the Green River carves through Red Canyon — 1,500-foot red rock walls sheltering one of the finest trout tailwaters in the American West. The cold, clear dam releases maintain year-round flows ideal for trophy brown and rainbow trout. Forty miles of Class I–III water through the Flaming Gorge National Recreation Area.
