Skagit River is the largest and most biologically important river draining into the Puget Sound. Starting in Canada, the river and its tributaries drain an area of 1.7 Million acres. It supports one of the largest bald eagle populations in the US, every native species of salmon, two species of trout and thousands of snow geese and trumpeter swans. A series of dams along the river provide 90% of Seattle’s electricity.
