The Skagit River System Cooperative (SRSC) provides natural resource management services for the Sauk-Suiattle Indian Tribe and the Swinomish Indian Tribal Community. On behalf of these two sovereign nations, SRSC works to actively improve fisheries management within their usual and accustomed fishing areas. These areas include the Skagit and Samish River basins, and were ceded to the United States through treaties signed in 1855. Fisheries management carried out by SRSC includes harvest and hatchery management, research, environmental review, habitat restoration, and a range of other activities.
