From alpine lakes and tailwaters to sprawling reservoirs and meadow streams, here are ten of the top fishing spots across Northern Colorado, Southern Wyoming, and the South Platte corridor.

Top Fly Fishing Destinations Across Northern Colorado & Beyond

1. Deckers (South Platte River)

One of Colorado’s most famous tailwaters, Deckers offers year-round fishing with technical conditions and highly pressured fish. Located below Cheesman Reservoir, this stretch is known for selective trout and consistent midge and baetis hatches.

2. Cheesman Canyon

Upstream of Deckers, Cheesman Canyon provides a more remote and scenic experience. This gold medal stretch rewards anglers willing to hike in with clear water, large trout, and technical presentations. Midges and Baetis are the major hatches seen almost year round in this section and it can be extremely rewarding to those who put in the effort.

3. Eleven Mile Reservoir

A premier stillwater fishery in South Park, Eleven Mile is known for trophy-sized trout including rainbows, browns, cutbows, and kokanee salmon. Its large, open water can be wind-affected, but when conditions line up, fishing can be exceptional. Shore anglers do well during spring and fall, while boats and float tubes allow better access to deeper structure and cruising fish. Effective techniques include chironomids, leeches, and streamer patterns, with dry fly opportunities during summer hatches.

4. The Dream Stream & Spinney Mountain Reservoir

The Dream Stream, stretching between Spinney and Eleven Mile Reservoirs, is one of Colorado’s most well-known tailwaters, offering clear water and large, migratory rainbow, brown, and cutthroat trout. It fishes best in spring and fall but can be technical due to pressure.

Spinney Mountain Reservoir is a gold medal stillwater fishery known for producing big, healthy trout. Chironomids, leeches, and damselflies are key, and float tubes or boats help anglers effectively cover water.

5. North Park Lakes (Delaney Buttes & Lake John)

These iconic lakes near Walden are known for producing trophy trout in a quiet, high-country setting. North and South Delaney Buttes Lakes and Lake John are favorites for stillwater anglers seeking big fish and fewer crowds. Expect opportunities for large rainbows, browns, and cutthroat, especially during calm mornings and evenings. Chironomids, leeches, and terrestrials are all effective depending on the season, and a float tube or small watercraft can greatly improve access and success.

6. Grey Reef (North Platte River, WY)

Located below Alcova Reservoir, Grey Reef is one of Wyoming’s most productive tailwaters. Known for high fish counts and consistent flows, it offers excellent nymphing and streamer fishing for large rainbow and brown trout. This section fishes well year-round, with prolific midge and blue-winged olive hatches, nymphing is especially effective from a drift boat, though wade access is available in select areas.

7. Miracle Mile (North Platte River, WY)

Between Seminoe and Pathfinder Reservoirs, the Miracle Mile is famous for its big trout and prolific insect hatches. This stretch can produce trophy fish, especially during streamer season and during hatches of midges, caddis, and blue-winged olives. When conditions are right, anglers can expect aggressive fish and consistent action in a rugged, remote setting.

8. Steamboat Springs (Yampa River)

The Yampa River through Steamboat Springs offers a mix of freestone and
tailwater fishing with healthy populations of brown and rainbow trout. Easy access through town and public stretches makes it a favorite, while nearby stretches provide more solitude and excellent dry fly opportunities.

9. Curt Gowdy State Park & Snowy Range (WY)

Located between Cheyenne and Laramie, Curt Gowdy State Park features several well-managed reservoirs like Granite and Crystal Lakes, offering great fishing for trout and warmwater species. Nearby, the Snowy Range provides high-elevation lakes and streams with cutthroat and brook trout in a scenic
alpine setting.

10. Laramie Plains Lakes (WY)

A collection of productive stillwaters including the Wheatland Reservoirs and the Laramie Plains Lakes, offer diverse fishing opportunities in a wide-open, prairie setting. These lakes hold trout as well as warmwater species like walleye and perch, providing variety for anglers. Fishing is often best from a boat or float tube, with success coming on leeches, chironomids, and baitfish patterns depending on the season.

From technical tailwaters like Cheesman Canyon to the expansive stillwaters of North Park and Wyoming, this region delivers an unmatched range of fishing opportunities.
