Having been born in sedro I've fished that river quite a bit and when still do (odds are that if your born in woolley you'll probably die there). Anyways for silvers I only fish lures, eggs work but their alot of work. Focus on current seams and rocks/logs/etc, my favorite lure is a silver blue fox size 4. These get a little costly and its easy to loose them so also try dick nites behind 3 feet of pencil led. If it gets slow I'll use a spoon with some green on it and bounce it along the bottom as long as there aren't alot of snags. This works well because silvers, dogs, dollies and steelhead will bite it.
