Well, I have never fished Omak and I probably will not. So the treasure is safe. Even if I did fish it, there is not a lot of danger to the fish. As far as the white bugger goes, perhaps it triggers a strike from movement of the soft feathers. Kinda of a I see, I eat, program. The only thing that might actually live in the water that is white might be, as stated a small bait fish sans dark back, or perhaps a white wax worm. A hungry trout will take most anything that moves and is smaller than it is. The problem is finding a hungry trout.
