Puget Sound boundaries

There are several ways that scientists and managers have defined the boundaries of Puget Sound. To oceanographers, Puget Sound includes the waters from Admiralty Inlet and Deception Pass to the southern tip of Olympia. However, many management and conservation efforts incorporate the entire watershed—the land where rivers and streams drain into Puget Sound—as well as the Strait of Juan de Fuca, Hood Canal and the San Juan Archipelago.
