Rivers: The Heart of the Action

The lifeblood of fly fishing in Grand County flows through its rivers, and two, in particular, stand out near Granby.
 

The Colorado River

The mighty Colorado River starts its journey right here in Grand County. The section flowing below the Granby Reservoir is a notable "tailwater" fishery, meaning it has consistent, cold water from the dam that creates ideal conditions for trout year-round. This is a designated Gold Medal Water, so you're fishing for quality, wild fish.

  • What to Expect: This section of the river is known for its healthy population of wild brown trout and stocked rainbow trout. You'll find a variety of water types, from deep pools to swift riffles, making it perfect for both nymphing and dry-fly fishing.

  • Access: Public access is available at pull-offs along Highway 40. You can also find guided-only access on private land, which can offer a more secluded experience.

The Fraser River

The Fraser River is the first major tributary of the Colorado and a fantastic small-to-medium-sized stream fishery. The river offers a variety of public access points, particularly around the towns of Winter Park and Fraser, but its waters also flow right through Granby.

  • What to Expect: The Fraser is a true "Grand Slam" river where you can target browns, rainbows, cutthroats, and brook trout all in one day. The river can be tricky to fish due to its smaller size and smart fish, but the reward is a beautiful, wild trout.

  • Access: A good way to find public water is to check out the Fraser River Trail, which runs alongside the river and offers easy walk-in access. There's also fishing available at Kaibab Park in Granby, where the Fraser River runs through.

Streams & Creeks

Grand County's creeks are a must-explore. These smaller waterways offer a peaceful escape and the chance to sight-fish for wild trout.

  • St. Louis Creek: This is a classic mountain stream, offering small-stream fly-fishing for a mix of cutthroat, brown, rainbow, and brook trout. It's a serene place to practice your cast without the pressure of a big river.

  • Willow Creek: Willow Creek has two great sections to explore. One is a wild stretch in the National Forest, and the other is the tailwater below the Willow Creek Reservoir. Both offer excellent opportunities for brown, rainbow, and brook trout, with some regulations in place to protect the fishery.

  • Muddy Creek: Located below Wolford Reservoir, Muddy Creek is another tailwater fishery that is a hidden gem for catching brown and rainbow trout. Just remember to check the flow levels before you head out.

Lakes & Reservoirs

Don't overlook the stillwater fishing available near Granby. These lakes and reservoirs provide a different challenge, often with the chance to land larger fish.

  • Lake Granby: As one of the largest bodies of water in Colorado, Lake Granby offers a huge amount of fishing space. Fly-fishing from the shore is a great option, especially in the spring, but a boat will give you access to a massive population of lake trout, kokanee salmon, and rainbows.

  • Shadow Mountain Lake & Grand Lake: These two lakes are part of the same system and are frequently fished together. Shadow Mountain is a spring favorite for large brown and lake trout, while Grand Lake offers a beautiful setting for fishing from docks or rented boats.

  • Monarch Lake: A non-motorized lake nestled in a stunning mountain bowl, Monarch Lake is perfect for a peaceful day of fly fishing. The lake is home to rainbow, brown, and brook trout, and notably, a record brook trout was caught here in 2022.

  • Williams Fork, Wolford, Meadow Creek & Willow Creek Reservoirs: These additional reservoirs offer diverse trout species, including northern pike. Tiger Trout also can be found at Meadow Creek Reservoir. 

  • High Alpine Lakes: For the most rewarding and scenic fly-fishing experience, consider a hike into one of Grand County's high alpine lakes. Found in the Rocky Mountain National Park and surrounding national forests at elevations of 10,000 to 12,500 feet, these lakes offer a true sense of solitude and home to wild brook and cutthroat trout. The fish here may not be as large, but their willingness to take a dry fly on a summer afternoon makes the hike more than worthwhile. The best time to visit these lakes is typically mid-summer through early fall after the ice has melted and the weather is stable. Be prepared for a moderate-to-strenuous hike and be aware of changing weather conditions.

Local Fly Shops & Gear

Before you head out, a visit to a local shop is highly recommended. The knowledgeable staff can provide up-to-the-minute information on river flows, current hatches, and the best flies to use.

  • Simply Outdoors: Offering a wide selection of fishing gear and a deep knowledge of the local area, Simply Outdoors is another excellent resource for your fly-fishing needs.

Etiquette & Safety

Fly fishing in the mountains comes with its own set of rules and precautions. Be mindful of these tips to ensure a safe and enjoyable trip:

  • Respect Private Property: Always be aware of property boundaries and only fish on public land or with permission.

  • Leave No Trace: Pack out all of your trash, including discarded fishing line.

  • Be Aware of Changing Weather: Mountain weather can change in an instant. Be prepared for afternoon thunderstorms, and always carry extra layers and rain gear.

  • Altitude Awareness: Granby sits at around 8,000 feet. Be aware of the effects of high altitude and stay hydrated.

  • Wildlife: You are in prime wildlife territory. Be aware of your surroundings and know how to react to encounters with animals like moose and bears.
