to healthy levels. An important, but often missing, component of
the plans is accurate information on wild chinook abundances and
the factors that limit or impact production and productivity in
key wild chinook stocks. One such key stock, Green River
chinook, represents one of the largest populations of chinook
within the Puget Sound Evolutionary Significant Unit (ESU).
Since quantifying juvenile anadromous salmonid populations as
they migrate seaward is the most direct assessment of stock
performance in freshwater,
