As daylight gets shorter it will effect fish migration. Usually after Laborday steelhead start to move into tributaries from some of the great lakes. Most of these fish have Skamania influence in them. Depending on location many streams will have decent to very good runs of steelhead by early october. These fish can be aggressive and do not die as do salmon.Early runs seem to take smaller baits and lures. Fly fishing in the lower clear water can be one of the best ways to catch these great fish. If you have never fished for them and looking for some fall-winter stream fishing these fish can give you a great experience.
