Encyclopedic overview

Puget Sound (/ˈpjuːdʒɪt/ PEW-jit) is a complex estuarine system of interconnected marine waterways and basins located on the northwest coast of the U.S. state of Washington. As a part of the Salish Sea, the sound has one major and two minor connections to the Strait of Juan de Fuca, which in turn connects to the open Pacific Ocean. The major connection is Admiralty Inlet; the minor connections are Deception Pass and the Swinomish Channel.

Puget Sound extends approximately 100 miles (160 km) from Deception Pass in the north to Olympia in the south. Its average depth is 450 feet (140 m) and its maximum depth, off Jefferson Point between Indianola and Kingston, is 930 feet (280 m). The depth of the main basin, between the southern tip of Whidbey Island and Tacoma, is approximately 600 feet (180 m).
