Yakoun Steelhead
It's a great river and fishable for Steelhead from about mid-Nov to March, although peak times are late December to late February. I don't live up there anymore but still have a buddy who guides on the Yakoun and prefers to flyfish. His name is Norm Desilets and his number is 250-557-4447. He will probably take you out to Branch 40 to start and possibly up to Canyon, however, there is a lot of good holding water. I recommend getting Norm to guide you for a day and then take a couple of days and do some walking.
Good Luck!
