Why Fly Fish for Carp in Colorado?
Carp have long been considered a nuisance species, but savvy anglers have discovered they’re actually one of the most challenging and fun freshwater species to fly fish.

Union Reservoir
Union Reservoir near Greeley is a prime carp fishery, with vast mud flats and shallow bays where carp feed openly. Early morning and late evening offer the best light conditions for spotting carp cruising the flats.

Best Tips for Fly Fishing Carp in Colorado
Timing Is Everything
Carp are most active during warmer months, typically in the summer months. The best times of day can often be morning and late afternoon when carp move onto flats to feed. Cloud cover and low wind can also improve your chances by keeping fish relaxed but visible.
Gear Up Properly
A 6-8 weight rod with a floating line is standard for carp fly fishing. Use long, supple leaders—often 12 to 15 feet—to present flies delicately. Carp have excellent vision and can be easily spooked by heavy tippet or harsh presentations.
Fly Selection
Effective carp flies mimic natural foods such as crayfish, leeches, and aquatic insects.
Approach and Presentation
Move slowly and minimize shadows on the water. Avoid sudden movements and keep a low profile. Cast just ahead of cruising carp and allow your fly to drift naturally. Patience is key—often carp will inspect a fly multiple times before deciding to eat.
Why Carp Fly Fishing Is Growing in Popularity
