From there, it generally flows southwest, passing through the Blue Mesa Reservoir, the Morrow Point Reservoir, and the Crystal Reservoir in Black Canyon of the Gunnison National Park. Then, the Gunnison river continues on to Grand Junction, eventually joining the Colorado River in Mesa County.
Offering exceptional fly fishing year-round, the Gunnison River, Colorado enjoys dueling designations as Gold Medal waters and Wild Trout water. That makes the Gunny an ideal spot for fly fishing in Southwest Colorado, where beginner and avid anglers alike can land record-breaking catches.
If you’re looking for a great place to fish in Southwest Colorado or if you’re planning your next trip to the Gunny in Black Canyon, here is everything you need to know about Gunnison River fly fishing so you can make the most out of your next adventure.
Best Places for Gunnison River Fly Fishing
The Gunnison River has two Gold Medal water stretches. Each has distinct characteristics that offer unique opportunities for Gunnison fly fishing in Southwest Colorado.
- The Lower Gunnison Basin: This 39-mile stretch of Gold Medal water extends from the Blue Mesa Reservoir, one of the Gunnison river's largest points, to the Delta. While the Blue Mesa Reservoir is home to a famed kokanee salmon fishery, the Gunnison Gorge downstream of Black Canyon is one of the most popular areas for anglers who visit the lower basin. The 20+-inch rainbow trout swimming in these waters are a big reason why.
- The Upper Gunnison Basin: Prized for offering some of the state’s finest fishing, the Upper Gunnison Basin refers to the 18-mile stretch from the Taylor Park Reservoir to the Blue Mesa Reservoir. Here, anglers can expect to encounter several species, from brook trout and cutthroat trout to mackinaw, cutbow, tiger trout, and rainbow trout. Legendary catches in these waters are true trophies. In fact, some record-breakers include mackinaw and rainbow trout measuring longer than 40 inches!
With good water quality, favorable stream flows, and a nice water supply 12 months a year, the Gunnison River, Colorado has optimal conditions for trout populations to thrive. In fact, Colorado Parks and Wildlife (CPW) estimates that the Upper Gunnison alone has:
- 141 to 234 pounds of trout per acre
- 41 to 70 trout, measuring at least 14 inches long, per acre
By comparison, the minimum to qualify as Gold Medal standard in Colorado is 60 pounds of trout per acre and a minimum of 12 trout (measuring at least 14 inches) per acre.
These conditions make the Gunnison River, Colorado an excellent choice for wade and float fly fishing (Class I & II at many flows) throughout the year.

Best Time For Gunnison Fly Fishing
There’s no bad time for Gunnison River fly fishing, but there may be better times to go based on:
- Your skill level: Winter can bring tougher conditions that are not ideal for novices. Generally, there are better flows and bigger hatches available in the summer, making that one of the best seasons to fly fish in Black Canyon, regardless of skill level.
- What you want to hook: The kokanee salmon usually spawn from August to October, while the trout fishing continues year round on the Gunny. The Black Canyon is most accessible in the spring/early summer depending on conditions due to the adverse hike in, which aligns with the perfect time to land large trout of many varieties.
