GSH are most likely illegal in WA as well. They are very stringent on what they do and don't allow to be stocked. Because they have been more isolated than much of the rest of the country, they're trying to not have all the problems of introduced species like most of the rest of the country has. WA state doesn't have an overly diverse native Cyprinid community though. Pickings are going to be slim and the odds of a hatchery raising any of the native species is not likely.
