I just looked at WDFW's trout and kokanee palm and species pages. Sutherland is still pointed out as a kokanee lake. A bio I know who worked in the Skagit watershed noted that genetic studies showed the "kokanee" taken in Baker were anadromous sockeye.

Even if they are no longer stocking kokanee, if they want to restore sockeye in Sutherland stop fishing for O. nerka.
