Most folks will stay on 16 and move to 9 when they are visiting with another fisherman. Kokanee will be scattered all over early in the season. Later I have my best luck on the south end from cape horn down to Bayview.
Even with winter fishing you might want to pull some flies on the top for Rainbow. We do quite well most years pulling flies off the boards during December, January and early February. I haven’t had quite as good a luck pulling plugs in the winter, at least not on the surface.
I fish mostly the south end of the lake so if you ever have a question feel free to shoot me an email.
