Tips Fly Fishing on the Middle Colorado River
Seasonal Tip
Focus on slower, deeper runs and pools where trout are conserving energy in cold water. Longer leaders and lighter tippet help ensure stealthy presentations.
Dry Fly
Look for brief midge hatches in calm water on sunny afternoons. Present small dries like Griffith’s Gnats gently to avoid spooking fish.
Nymphing
Double-nymph rigs with a Zebra Midge and a Black Beauty are highly effective. Use split shot to get your flies down to feeding fish.
Streamer Fishing
Streamers like Slump Busters or small sculpin patterns fished slowly can provoke strikes from larger trout holding near structure.
