The Lake Washington Ship Canal, which runs through the city of Seattle, Washington, connects the fresh water body of Lake Washington with the salt water inland sea of Puget Sound. The Hiram M. Chittenden Locks accommodate the approximately 20-foot difference in water level between Lake Washington and the Sound. The Canal runs east/west, and connects Union Bay, Lake Union, the Montlake Cut, Portage Bay, the Fremont Cut, Salmon Bay, and Shilshole Bay, with the Sound, which empties into the Pacific Ocean.
