January – Confluence staff led this important project that has the goal of improving the health of salmon populations along Puget Sound’s shorelines. Confluence led a team that identified and characterized 196 streams and 13 embayments that cross the BNSF Railway along Puget Sound shoreline between Olympia and Canada. Work included creating and applying a prioritization framework that identifies stream or embayment habitat priorities for Chinook salmon. The project team led by Confluence included representatives from Environmental Science Associates, the Tulalip Tribes, and Coastal Geologic Services. BNSF provided strategic and safety guidance, and access to sites. For more information on the project and future opportunities, see this fact sheet.
