Man, nobody's given you a reply yet? My folks live in Sequim and there's alot of decent flyfishing in the NE corner of the O.P.
A few halfway decent lakes nearby include Gibbs, Tarboo, Leland, Anderson, Sandy Shore, Teal, and others. Take your pick.

Good Searun Cutthroat fishing can be had at many local beaches, but I'd be a "marked man" if I revealed any of these to you.
