The Stillaguamish Watershed Council (SWC) is focused on maintaining a healthy Stillaguamish River watershed through collaboration with various stakeholders since 1990. The Stillaguamish Tribe of Indians has restored approximately 25 acres at Pilchuck Park, enhancing fish and wildlife habitat and creating public access with trails and educational kiosks. The efforts include restoring wetlands and installing large woody debris to support local aquatic life, including Chinook and Coho salmon.
