Gold Medal Tailwaters — World-Class Trout

Colorado's Gold Medal Waters designation means the stream produces trout 14 inches or larger at a rate of 60 pounds per acre. These tailwater fisheries below major dams offer consistent year-round fishing in crystal-clear water.

South Platte River (Cheesman Canyon)

Deckers, CO · River

Advanced

Cheesman Canyon on the South Platte is Colorado's most famous trout stream — a Gold Medal canyon with gin-clear water, technical fish, and dramatic granite walls. Wild brown and rainbow trout average 14-18 inches, with fish over 24 inches present.

🌸 Spring ☀️ Summer 🍂 Fall

🎯 Expert Tip

Extreme stealth required — long leaders (12-15 feet), 6X-7X tippet, size 18-24 midges and Blue-Winged Olives. The canyon hike is steep but rewards you with less pressure. Catch-and-release, flies and lures only. Best from May through October.

Frying Pan River

Basalt, CO · River

Intermediate

The Frying Pan River below Ruedi Reservoir is one of Colorado's premiere Gold Medal tailwaters. Consistent cold-water releases create ideal trout habitat year-round. The "Toilet Bowl" pool near the dam holds some of the largest trout in the state — fish over 10 pounds.

🐟 Rainbow Trout 🐟 Brown Trout 🐟 Brook Trout
🌸 Spring ☀️ Summer 🍂 Fall

🎯 Expert Tip

The first mile below the dam (catch-and-release, flies/lures only) holds the biggest fish. Midge patterns (size 20-24) are essential year-round. The evening Pale Morning Dun hatch in July produces excellent dry fly fishing. Wade carefully — flows fluctuate.

Colorado River (Pumphouse to State Bridge)

Kremmling, CO · River

Intermediate

This Gold Medal stretch of the Colorado River flows through remote high-desert canyon country with far less pressure than the South Platte. Big brown trout and healthy rainbow populations make this a premier float-fishing destination.

🐟 Rainbow Trout 🐟 Brown Trout 🐟 Mountain Whitefish
☀️ Summer 🍂 Fall

🎯 Expert Tip

A rafted fly fishing trip through Gore Canyon is the best way to access this water — multi-day float trips cover miles of productive water. Streamers and large stonefly nymphs produce the biggest fish. Summer (July-August) is optimal for flows.

High Country Lakes — Alpine Paradise

Colorado has hundreds of high-altitude lakes and reservoirs between 8,000 and 13,000 feet. These mountain waters hold cutthroat, rainbow, brook trout, and in some larger reservoirs, trophy lake trout and kokanee salmon.

Blue Mesa Reservoir

Gunnison, CO · Reservoir

Beginner

Colorado's largest body of water, Blue Mesa is the state's top kokanee salmon destination and an excellent lake trout fishery. The reservoir sits at 7,519 feet in the stunning Gunnison Valley with breathtaking mountain scenery.

☀️ Summer 🍂 Fall

🎯 Expert Tip

Kokanee salmon: troll small flasher-and-hoochie rigs 30-50 feet deep from July through September. Lake trout: troll large spoons deep (80-120 feet) or jig vertically. The kokanee snagging season in September at the Gunnison River inlet is a fun tradition.

Spinney Mountain Reservoir

Hartsel, CO · Reservoir

Intermediate

Spinney Mountain sits at 8,700 feet in South Park and produces some of the largest trout in Colorado — rainbows and browns exceeding 10 pounds. Pike over 20 pounds are also present. This is a trophy-focused fishery with special regulations.

🐟 Rainbow Trout 🐟 Brown Trout 🐟 Northern Pike 🐟 Cutthroat Trout
🌸 Spring 🍂 Fall

🎯 Expert Tip

Float tube or belly boat with chironomid (midge) patterns suspended under a strike indicator in 10-20 feet. The spring ice-off (April-May) and fall turnover (September-October) are the best windows. Bag, possession, and size limits are restrictive — check regulations.

High Alpine Lakes (Continental Divide)

Various, CO · Lake

Advanced

Colorado has hundreds of alpine lakes above timberline (11,500+ feet) holding native greenback cutthroat trout — the state fish. These remote, pristine lakes require hiking but offer a fishing experience that combines wilderness adventure with eager, unsophisticated trout.

☀️ Summer

🎯 Expert Tip

Most alpine lakes are fishable July through September — snow melts late at altitude. Pack lightweight ultralight spinning tackle or a 4-weight fly rod. Small dry flies (size 14-16 Adams, Elk Hair Caddis) work on nearly every alpine lake. Check OHV and wilderness access rules.

Front Range & Warm Water

Colorado's eastern plains and Front Range reservoirs offer surprisingly good warm-water fishing — walleye, wiper, bass, and catfish — close to the Denver metro area.

Horsetooth Reservoir

Fort Collins, CO · Reservoir

Beginner

Horsetooth Reservoir sits beneath dramatic red sandstone hogbacks just west of Fort Collins. The lake offers excellent smallmouth bass fishing (rare in Colorado) along with walleye, lake trout, and aggressive wiper (hybrid striped bass).

🐟 Smallmouth Bass 🐟 Walleye 🐟 Lake Trout 🐟 Wiper
🌸 Spring ☀️ Summer

🎯 Expert Tip

Smallmouth bass hold on the rocky points and dam face — drop-shot tubes and crankbaits. Wiper chase bait schools in open water — cast topwater when you see them busting shad on the surface. Lake trout deep in winter. Park pass required ($10/day).

Eleven Mile Reservoir

Lake George, CO · Reservoir

Intermediate

Eleven Mile Canyon and Reservoir in the high-altitude South Park basin offer both excellent stillwater fishing and a Gold Medal stream section. The reservoir is famous for its ice fishing, and the canyon tailwater below the dam is a beautiful freestone trout stream.

🐟 Rainbow Trout 🐟 Brown Trout 🐟 Northern Pike 🐟 Kokanee Salmon 🐟 Carp
🌸 Spring ❄️ Winter

🎯 Expert Tip

Ice fishing (December–March) for trout and pike is the main draw. Open water: troll or still-fish with PowerBait near the inlet. The canyon stream below the dam is catch-and-release, flies/lures only — excellent pocket water for wading.
