Gunnison River, CO fishing report
The Gunnison gorge and the gold medal tailwater below the dams are predominantly a brown and rainbow trout fishery, and that's what most serious anglers come for. The tailwater stays cold and relatively consistent year-round, which keeps trout feeding even in summer when freestone streams go slack. Browns move shallow and become aggressive in fall as spawn behavior kicks in. Smallmouth bass show up in the warmer canyon stretches and can be genuinely excellent through summer. Walleye, catfish, and panfish are incidental players in slower, deeper pools, and chain pickerel are rare enough here that treating one as a bonus catch is the honest framing.
In the gorge, fish hold tight to seams behind midstream boulders and along undercut walls where cold oxygenated current meets slower water. Euro-nymphing with small Pat's Rubber Legs, RS2s, or Zebra Midges under an indicator covers the technical water well. Watch flows carefully — releases from upstream dams can push fish off feeding lies quickly, so fish early before afternoon generation ramps up. Streamer fishing big weighted sculpins and woolly buggers draws aggressive strikes from larger browns in low-light periods. When water temps drop below 45 degrees, slow your drift and go small. For smallmouth in the canyon, crayfish-pattern soft plastics worked along rocky shelves in mid-summer heat are hard to beat.
