The Northern California Fly Fishing Board

I've fished the Big Horn in eastern Wyoming in early winter and done well. Bitch Creeks and Girdle bugs worked real well. You could watch the big (last time I was there we were averaging 18-20 inch fish) Rainbows cruise up almost hanging vertical in the current and eye them then take them. In my experience - in winter the fish are not interesred in expending much energy. You need to bring the fly close to them (you really do better if you can see the fish you are casting to) and big flies are better. And more often than in warmer weather, no matter what you do they just aren't interested. I can give you good info if you are going to be at the Big Horn...let me know.
