Tips for Fly Fishing on the Colorado River
- Seasonal Tip: As water temperatures rise, trout become more active. Focus on transitional zones where fast water meets slow, as fish often hold in these areas.
- Dry Fly: Look for rising fish in the afternoons, especially during Blue Winged Olive hatches. Present flies upstream and allow a natural drift over feeding lanes.
- Nymphing: Utilize a double nymph rig with a heavier point fly and a smaller dropper. Adjust indicator depth to target fish holding near the bottom.
- Streamer Fishing: During early mornings or cloudy days, streamers can entice larger trout. Cast across and slightly downstream, retrieving with varied speeds.
