This study is needed to better understand the causes of decline for two ESA listedsalmonid species that have at least a portion of their juvenile population exhibiting astream type life history: Chinook (Oncorhynchus tshawytscha) and steelhead (O. mykiss). The study’s purpose is to identify seasonal and habitat type preferences in freshwaterhabitat in the Skagit River basin by answering the following questions:1. What habitat types are used by fish seasonally?2. Where are fish located within the basin seasonally?3. Where are habitats (by type) within the basin?
