The Gunnison River, one of Colorado’s most diverse fisheries, offers a mix of freestone and tailwater fly fishing. Flowing from Almont through Blue Mesa Reservoir and into deep canyons, it’s home to vibrant rainbow, brown, and cutthroat trout populations. With consistent flows due to dam releases, it provides excellent year-round fishing opportunities for both waders and float fishers alike.
The Gunnison River is delivering a stellar fall season! With flows around 415 CFS, the river is primed for wade fishing, and the cool water temps in the low 50s have trout feeding actively throughout the day. This month, the Gunnison’s famous “Gunny Green” water clarity and the surrounding fall colors make for a gorgeous setting. Anglers can expect the browns to be in pre-spawn mode, adding some aggression to their takes – ideal for streamer fans and nymphers alike.

Seasonal Tip
With pre-spawn browns getting aggressive, don’t shy away from larger presentations. Streamer fishing has been especially productive on cloudier days, with big browns willing to chase down moving patterns.
Dry Fly
The Blue Wing Olive hatch continues to draw surface action, especially mid-morning. Target slower pools and seams with a BWO in sizes #18-22.
Nymphing
Nymph rigs with small Baetis nymphs are landing consistent fish. Start with a heavier fly like a Copper John or a San Juan Worm to anchor your rig, followed by a Baetis or midge pattern.
Streamer Fishing
For those chasing the bigger trout, streamers are the name of the game. Olive or black Sculpzillas are effective, especially when retrieved with slow, steady strips along structure.
This section of the Gunnison is mostly public, especially within the Gunnison Gorge National Conservation Area. Respect private property boundaries outside of these zones. As brown trout enter their pre-spawn season, avoid wading in shallow, spawning areas to protect future populations.
