Since ESA listings for Chinook are based on the status of an Evolutionarily Significant Unit (ESU) and Willapa Chinook are only a part of the Washington Coast Chinook ESU, its seems unlikely to me that Willapa problems by itself would result in an ESA listing. It would seem like other populations within the ESU would also need to be determined to be at risk. Doesn't seem like this is the case, for now anyway.
