Colorado is a premier destination for fly fishing, boasting thousands of miles of Gold Medal streams and pristine high-country lakes. This guide provides essential information for a successful and responsible fishing experience.

Gold Medal Waters

Colorado Parks and Wildlife (CPW) designates certain stretches of rivers as "Gold Medal Water," which signifies that the water can consistently support 60 pounds of trout per acre and at least four trout over 14 inches long per acre. These areas offer exceptional fishing but often have specific regulations (e.g., catch and release, flies and lures only).

Here are a few notable Gold Medal Rivers in Colorado:

• Arkansas River: Known for Brown Trout and Rainbow Trout.
• Blue River: Excellent tailwater fishery below Dillon Reservoir.
• Gunnison River: The Black Canyon offers spectacular, challenging fishing.
• Fryingpan River: A world-class tailwater near Basalt, known for large Rainbows.

Essential Gear and Flies

While gear can vary widely based on location and time of year, here is a general list:

Rod and Reel

Item	Description	Tip
Fly Rod	9-foot, 5-weight	The most versatile rod for Colorado rivers.
Fly Reel	Matching reel with reliable drag	Spool with weight-forward floating line.
Leaders/Tippet	4x, 5x, and 6x	Essential for presenting smaller flies naturally.

Recommended Fly Selection (Must-Haves)

• Dry Flies: Parachute Adams, Elk Hair Caddis, Royal Wulff
• Nymphs: Pheasant Tail, Hare's Ear, Prince Nymph, Pat's Rubber Legs

Colorado Fishing Regulations

All anglers aged 16 and older must possess a valid Colorado Fishing License. Always check the CPW website for the most up-to-date regulations, as rules can vary drastically between different bodies of water.

Key Regulations

• License: Must be carried on your person while fishing.
• Seasons: Fishing is generally open year-round, but specific closures may apply.
• Bag Limits: Varies by location. Many Gold Medal sections are strictly catch-and-release.
• Aquatic Nuisance Species (ANS): Mandatory cleaning and drying of all equipment (Waders, boats, nets) to prevent the spread of invasive species like Zebra Mussels.

To ensure you have the required license and know the current regulations, please refer to the CPW official document: File

River Safety and Etiquette

Fishing responsibly ensures a pleasant experience for everyone and preserves the environment.

Safety Tips

1. Wading: Always use a wading belt. Rivers can be cold and currents strong. Use a wading staff for stability.
2. Weather: Mountain weather changes rapidly. Carry rain gear, even on sunny days.
3. Hydration: Drink plenty of water, especially at high altitudes.

Angler Etiquette

• Respect Private Property: Do not trespass. Access public waters only via designated public access points.
• Wade Wisely: Avoid disturbing fish or other anglers by wading unnecessarily.
• Give Space: Maintain a respectful distance from other anglers. If fishing a drift, allow the angler ahead of you ample time to move downriver.
• Practice Catch and Release: Handle fish gently with wet hands, keeping them in the water as much as possible for a quick release.

If you are interested in a guided trip, consider booking with a local outfitter. A good option is located in Place.

High-Country Fishing

Colorado is famous for its remote alpine lakes and streams, which are often accessible only via hiking trails. These waters are home to native Cutthroat Trout. Plan your high-country trip carefully and pack for all conditions.
