Abstract

The Upper Willamette River (UWR) Chinook salmon Ecologically Significant Unit (ESU) includes naturally spawned Chinook salmon originating from the Clackamas River and from the Willamette River and its tributaries above Willamette Falls, as well as Chinook salmon from six artificial propagation programs. UWR Chinook salmon migrate through highly industrialized Portland Harbor (an active Superfund site) in the lower Willamette River, despite historical contamination. Juvenile salmon may be especially vulnerable to toxicant exposures.
