Rivers to Fly Fish in Colorado, Montana & Utah
If you're itching to get back to trout fishing, the Rockies offer an early-season fly fishing fix like no other. Spring and fall are the two best seasons to fly fish the Rockies.
Top 4 Must-Fish Rivers in the Rockies This Spring
South Platte River – Cheesman Canyon, Colorado
Cheesman Canyon is a challenging yet rewarding destination for fly anglers. The South Platte River carves through this granite canyon, creating holding water for selective rainbow and brown trout. Large nymphs and streamers are effective, but don't overlook dry fly fishing—midges and Blue Winged Olive hatches can provide exciting opportunities.
Frying Pan River – Basalt, Colorado
When spring runoff makes other rivers unfishable, the Frying Pan River remains a reliable option. Fed by releases from Ruedi Reservoir, this tailwater offers consistent flows and is home to healthy rainbow, brown, and cutthroat trout. The Gold Medal section near Basalt is particularly renowned, and the upper Frying Pan above the dam is also worth exploring when flows are manageable.
Yellowstone River – Livingston, Montana
The Yellowstone River is famous for its big brown trout, and spring is the best time to catch them. In mid-April, rising water temperatures prompt fish to move from their winter holes to the banks, making streamer fishing effective. A few weeks later, the Mother's Day caddis hatch brings prolific insect activity, offering excellent dry fly fishing opportunities.
Green River – Flaming Gorge, Utah
The Green River below Flaming Gorge Reservoir is a dry fly angler's dream. Expect prolific hatches of Blue Winged Olives in April and cicadas in May, with plenty of rising fish. The river flows through a scenic, steep-walled canyon, and the release of warm water from the reservoir encourages trout to feed actively. Early season months offer some of the best fishing, often without the crowds.
FAQs
When is the best time to fly fish in the Rockies during spring?
Early to mid-spring, particularly April and May, is ideal. This period features warming water temperatures and prolific insect hatches, prompting trout to feed actively.
What gear is essential for early season fly fishing in the Rockies?
Essential gear includes waders, layered clothing for variable weather, a selection of nymphs, streamers, and dry flies (especially midges and Blue Winged Olives), and a reliable fly rod and reel setup.
Are there any specific techniques recommended for these rivers?
Yes. For Cheesman Canyon, precise presentations with small dry flies or nymphs are effective. The Frying Pan River responds well to tailwater techniques with consistent drifts. Streamer fishing is productive on the Yellowstone River during pre-runoff, and dry fly fishing is excellent on the Green River during hatches.
Do I need a guide to fish these rivers?
While not mandatory, hiring a local guide can enhance your experience, especially if you're unfamiliar with the river's nuances or seeking to improve your skills.
Are these rivers suitable for beginner fly anglers?
Some rivers, like the Frying Pan and Green River, are more beginner-friendly due to consistent flows and accessible fishing spots. Cheesman Canyon and the Yellowstone River may present more challenges and are better suited for experienced anglers.
What regulations should I be aware of when fishing these rivers?
Regulations vary by state and river. It's crucial to check local fishing regulations, including licensing requirements, catch-and-release rules, and specific gear restrictions before fishing.
