Just as a side note: I grew up in the Tri-cities and have caught steelhead in that area. I have caught and know of severval people, that have caught large natives 20+ in the reach area up near white bluffs. There are natives in that area, but the numbers are few. I also know a guy who fly fishes in the winter(or used to)(below the wooden power lines) and catches(and releases) large undeformed fined steelies. These fish chase huge maribous. This cold water pursuit of flies, is more characteristic of natives, not hatchery plants. But perhaps they are hybrid, but what I have seen from natives from these parts, and from hatchery fish here and there..they sure seem to be native.
