I'm thinking whitefish, also. If your steelhead "0 for_" numbers get too frustrating, you might want to target those bony bugeaters. With a new GLoomis whitefish rod, some gold #14 Gammis, and a hydraulics permit to screen bait off the stream bottom, you could be experiencing fishing success. Since whitefish are neither commercially sought, nor actively managed by NMFS or WDFW, the future of this fishery appears bright. Current whitefish regs allow the retention of 15 fish with no minimum size. You will have one dilemma, though...all the fish you catch will be natives.
Good fishun'.
