Boulder Creek is fishing great. I have been fishing the lower section (below 4 Mile) and it has just been awesome. The terrestrial bite has been good, as well as attractors; both on top and below. Today, we were throwing a new nymph I tied up recently that was previously untested. This little (large) fly was banging the doors. It has no name yet, although it will be named and available for sale soon, only on this web site. This guy was catching em' though, and larger than normal fish as well. As I said, look for them on the nymph page soon.
Other flies that have been hot are beetles, ants, copper johns, prince nymphs, rainbow warriors, blue poison tungs, PMD's, PMX's, Amy's Ants, Stimmy's, Sallies, Para Adams, Spinners, Caddis, etc.
Just see what doesn't catch fish in the creek right now. You will be surprised.
