The Bald Eagle Unit is accessible ONLY by boat. It consists of 603 acres of undisturbed mature forested habitat that occurs in several parcels along the south bank of the Skagit River and the east and west banks of the Sauk River (confluence of the two rivers). The unit was acquired by the Department of Game in 1975-76 with the assistance of The Nature Conservancy for the conservation and protection of bald eagle winter habitat and roost sites.
