I spent yesterday morning fishing the South Platte River, just south of Denver for carp. I found a good number of them, but could not get any to eat what I was offering. I have had good luck at a local lake with Barry's Carp Flies and Clouser Swimming Nymphs, but these river carp were not interested. I also tried a BH hare's ear, a pheasant tail, and a light green soft hackle. No interest in any of them. The carp were feeding, I just couldn't figure out what they were going for. The smallest flies I tried were about a size 14-16, so I may not have gone small enough. I tried using a dead drift and a very slow retrieve, but could not interest them at all.

Any suggestions are appreciated...

Thanks,
Ted
