Directions
About this water

Above Blue Mesa the Gunnison is a broad, friendly snowmelt freestone, gathering the Taylor and the East at Almont and rolling down through town as honest brown-and-rainbow water. CPW made the Twin Bridges-to-Almont stretch Gold Medal in 2023, which surprised nobody who'd fished it. It's a big-water summer river — salmonflies and stoneflies, then caddis and hoppers once the runoff clears — with the easy float-and-wade character the canyon water downstream most definitely lacks. The high tributaries hold native cutthroat; treat those headwaters gently.
