Top 5 Fishing Locations on Gunnison River
Black Canyon of the Gunnison
The Gunnison through the Black Canyon holds some of Colorado's largest wild brown and rainbow trout in one of North America's most dramatic gorges. Access requires a challenging hike down steep trails but rewards with trophy fish that rarely see artificial flies. This is a serious backcountry fishing destination for experienced anglers.
💧 Ideal flow: 400–800 CFS. The Black Canyon section requires hiking in — check flows before committing to the trail as high water makes wading dangerous.

East Portal
East Portal Road provides the most accessible route into the Black Canyon for fishing. The Gunnison here flows through towering canyon walls with excellent wild trout in an awe-inspiring setting. Fish averaging 16-20 inches make the steep descent worthwhile.
💧 Ideal flow: 300–700 CFS. The lower canyon fishes well at moderate flows with large brown trout holding in deep pools.

Gunnison Gorge NCA
Below the national park the Gunnison Gorge National Conservation Area provides raft and hike-in access to exceptional wild brown and rainbow trout water. The gorge section holds the largest concentration of trophy trout on the entire river. Guided float trips are the easiest way to access the best water.
💧 Ideal flow: 200–500 CFS. Near Gunnison the river is more accessible — moderate flows allow good wade fishing throughout the season.

Blue Mesa Tailwater
Below Blue Mesa Reservoir the Gunnison tailwater produces excellent brown and rainbow trout fishing in cold productive water. This section is more accessible than the canyon stretches and produces consistent quality fishing. Midge and baetis hatches are important year-round.
💧 Ideal flow: 300–600 CFS. Blue Mesa tailwater sections fish best at consistent flows — watch for sudden releases from the reservoir.

Delta Section
Near Delta where the Gunnison approaches the Colorado River large brown trout inhabit deep pools in the slower wider river. Float fishing is the most effective approach to cover this expansive water. Fall produces the best fishing as trophy browns begin their spawning migrations.
💧 Ideal flow: 200–500 CFS. Fishes best at low to moderate flows when fish are visible and accessible in the upper canyon sections.

About Gunnison River Fishing
The Gunnison River carves through the Black Canyon of the Gunnison, one of North America's most dramatic and breathtaking gorges, creating a fly fishing experience unlike any other in Colorado. The river's Gold Medal section demands serious commitment—steep canyon walls and rugged terrain require significant hiking—but reward anglers with abundant trophy-sized trout in pristine, less-pressured water.
Best Time to Fish Gunnison River
The Gunnison's upper sections near the town of Gunnison peak during summer months when robust Baetis hatches (particularly in June and July) and prolific Caddisfly emergences drive aggressive feeding. Fall brings excellent conditions as cooler water temperatures and diminished crowds coincide with reliable October Caddis hatches and strong streamer fishing.
Species
Brown Trout dominate the Gold Medal section of the Black Canyon, where they grow large and aggressive in the canyon's nutrient-rich waters, responding exceptionally well to nymphs and streamers. Rainbow Trout are more prevalent in the upper, accessible sections near Gunnison and typically show strong rises to dry flies during the river's consistent daily hatches.
Access & Regulations
Always check the current Colorado fishing regulations before heading out. Regulations on Gunnison River may include special catch-and-release sections, artificial-only stretches, and seasonal closures. A valid Colorado fishing license is required.
