The goal of this study is to use eDNA as a cost effective tool for documenting the occurrence and distribution of ESA-listed spring-chinook (Oncorhynchus tshawytscha) throughout the Okanogan and Methow watersheds in an effort to map habitat use and connectivity. Our approach will use eDNA to detect low density spring-chinook in filtered water samples to inventory distribution and re-colonization of tributaries at strategically-sampled points throughout entire stream networks. This approach will provide one of the first applications of eDNA technology for monitoring distribution of native fish species of conservation concern. The findings will help the Colville Tribe Fisheries Managers assess aquatic connectivity...
