Sauk-Suiattle Indian Tribe

The Sauk-Suiattle Indian Tribe initiated a pilot study to assess the impacts of anticipated climate changes to both tribal infrastructure and the Sauk river ecosystem that supports fish and wildlife critical to the tribe. The Sauk-Suiattle Indian Tribe’s homeland encompasses a broad area including the Sauk and Cascade River watersheds in northwestern Washington. The Tribe wanted to know whether the warming climate could worsen flood and erosion risks, and whether changes could adversely impact salmon habitat. This report focuses on flood an erosion risks and how they may be impacted by climate change. The objectives of this report are to: (1) describe the hydrology and geomorphology the Sauk River near the reservation, (2) evaluate available information on potential for climate change to affect future flood flows in the Sauk River basin, (2) document historical changes in river channel and floodplain characteristics of the Sauk-Suiattle Reach, and (3) evaluate the near-term and future threats to tribal infrastructure posed by Sauk River streambank erosion and flooding.
