Midges and Blue Winged Olives are abundant during this time, making them go-to flies for early spring fishing.

April: As temperatures rise, April brings increased insect activity and hungry trout. The Arkansas River near Salida and the Roaring Fork River are prime spots for catching feisty rainbows and browns. Be prepared to match the hatch with caddis, stoneflies, and mayflies as they become prevalent during this month.

May: May heralds the peak of spring fishing in Colorado, with rivers teeming with aquatic life and hungry trout. The Gunnison River's Gold Medal waters and the Animas River in Durango offer superb fishing conditions.

Terrestrials remain productive, while hopper patterns excel on the state's freestone rivers.

Tips for Successful Fly Fishing in Colorado

  1. Stay Informed: Keep an eye on local fishing reports, water conditions, and hatch charts to plan your fishing trips effectively. Websites, forums, and social media groups dedicated to Colorado fly fishing can be valuable sources of information.

  2. Dress for Success: Colorado's weather can be unpredictable, so dress in layers to stay comfortable throughout the day. A good pair of waders and sturdy wading boots are essential for navigating rocky riverbeds and staying dry in cold mountain streams.

  3. Match the Hatch: Pay close attention to the insects hatching on the water and choose fly patterns that mimic them. Carry a variety of nymphs, dry flies, and streamers to cover different stages of insect life cycles and varying water conditions.

  4. Practice Stealth: Approach fishing spots cautiously to avoid spooking wary trout. Stay low, move slowly, and use natural cover to conceal your presence. Be mindful of your shadow and avoid making sudden movements that could alarm the fish.

  5. Experiment with Techniques: Don't be afraid to try different fishing techniques until you find what works best on a particular day. Whether it's dead-drifting nymphs, swinging streamers, or presenting dry flies with delicate precision, adapt your approach to the conditions and the behavior of the fish.

  6. Respect the Resource: Practice catch-and-release whenever possible to conserve Colorado's precious trout populations for future generations. Handle fish gently, use barbless hooks to minimize harm, and avoid fishing in spawning areas during sensitive times of the year.

  7. Embrace the Journey: Fly fishing in Colorado is about more than just catching fish—it's about immersing yourself in the natural beauty of the landscape, connecting with the rhythms of the river, and finding solace in the wilderness. Take time to appreciate the sights, sounds, and serenity of your surroundings as you pursue your passion for angling.
