So let me see if I understand.

The Willapa Bay hatchery Chinook came from the native Chinook populations within each of the tribs, except for Nemah. There are still Chinook in the Willapa, mostly hatchery fish or progeny of hatchery fish, which came from the native populations. So how are the fish that are now produced (hatchery and natural) in the Willapa basins non-native again?

Also, the Naselle Hatchery is no longer releasing millions of Chinook salmon. Additionally, the fisheries have changed in the last few years to reduce the Bay harvest rate on Naselle Chinook.

Also, I'm not confused about what goes on in the Willapa, it's more my confusion with other people understanding of it.
