The population of whitefish on the South Fork of the Skykomish, Tye, Beckler is very poop. The floods of these rivers really had an effect on them. Was a time when the population was decent. The people I know that used to fish it now fish Duvall area. Some whitefish travel like salmon or steelhead to spawn. If you look at the fish count for Whitefish at Sunset falls you will see its pretty dismal. You should have fished the Tye river in the good old Days
