This 102 miles river is one of those bodies of water in Colorado that received a Gold Medal Listing as a trout site.
The Arkansas River is situated in a high-desert environment with a combination of both warm and dry climates suitable for brown trout, rainbow trout, and other big fishes.
It’s also a prime location for both kayakers and rafters who is into white-water adventures. Since there’s a large population of trout in this river, fishing throughout the season is permitted.
Gunnison River
The Gunnison River is Colorado’s second-largest river, that’s 78 miles long. It’s renowned as native trout water. This river offers large rainbow trout, brown trout, and even land kokanee salmon.
However, expect to traverse through windy and steep roads, but you’ll surely be amazed by its sceneries, so hiking is also a must-try activity within the area.
The Gold Medal Trout Water section runs through the Black Canyon National Park. Since it’s a large river, you need to be familiar with the section where you plan to fish because of the changing water current.
South Platte River
This river is known as the gold medal western trout that offers different fly fishing sights, so you can’t go wrong wherever you plan to cast the line. The spring season is the best time to catch trophy spawners in the South Platte River.
What’s good about having fishing activities in this river is that it’s easily accessible. No doubt, it gets crowded at times.
Its area begins in South Park and flows down through downtown Denver. The South Platte River is also considered a tailwater fishery with seven dams situated on it.

The North Platte River is a great destination for wading fishing, where different kinds of big fishes like largemouth bass, bluegill, walleye, yellow perch, and other trophy-sized fish can be captured.

This 70 miles river is described to be a powerful river that’s swift and deep. It features two sections of Gold Medal Waters. The first section is between Aspen and Basalt, Colorado, and the other section is at the intersection of Crystal River up to the Colorado River.
Since Roaring Fork River has deeper waters, fly fishing or float fishing is the best productive fishing method used.
When you fish upstream, rainbow trout and wild brookies are abundant, while moving downstream offers your browns, rainbows, and mountain whitefish.
This river offers year-round hatches, so fishing in winter still gives you abundant catches.
Fryingpan River
