It is defined as bounded to the north by the international boundary with Canada, and to the west by a line running north from the mouth of the Sekiu River on the Olympic Peninsula. Four of these (including South Puget Sound) correspond to areas within the USGS definition, but the fifth, called "Northern Puget Sound" includes a large additional region. It does not include Bellingham Bay, Padilla Bay, the waters of the San Juan Islands or anything farther north.Īnother definition, given by NOAA, subdivides Puget Sound into five basins or regions. Under this definition, Puget Sound includes the waters of Hood Canal, Admiralty Inlet, Possession Sound, Saratoga Passage, and others. The third entrance is at the south end of the Swinomish Channel, which connects Skagit Bay and Padilla Bay. The second entrance is at Deception Pass along a line from West Point on Whidbey Island, to Deception Island, then to Rosario Head on Fidalgo Island. The main entrance at Admiralty Inlet is defined as a line between Point Wilson on the Olympic Peninsula, and Point Partridge on Whidbey Island. The USGS defines Puget Sound as all the waters south of three entrances from the Strait of Juan de Fuca. Ī different term for Puget Sound, used by a number of Native Americans and environmental groups, is Whulge (or Whulj), an anglicization of the Lushootseed name x̌ʷə́lč, which means "sea, salt water, ocean, or sound". This name later came to be used for the waters north of Tacoma Narrows as well. In 1792 George Vancouver gave the name "Puget's Sound" to the waters south of the Tacoma Narrows, in honor of Peter Puget, a Huguenot lieutenant accompanying him on the Vancouver Expedition. Puget Sound is also the second-largest estuary in the United States, after Chesapeake Bay in Maryland and Virginia. Major cities on the sound include Seattle, Tacoma, Olympia, and Everett. The term "Puget Sound" is used not just for the body of water but also the Puget Sound region centered on the sound. Sometimes the terms "Puget Sound" and "Puget Sound and adjacent waters" are used for not only Puget Sound proper but also for waters to the north, such as Bellingham Bay and the San Juan Islands region. In 2009, the term Salish Sea was established by the United States Board on Geographic Names as the collective waters of Puget Sound, the Strait of Juan de Fuca, and the Strait of Georgia. The depth of the main basin, between the southern tip of Whidbey Island and Tacoma, is approximately 600 feet (180 m). Its average depth is 450 feet (140 m) and its maximum depth, off Jefferson Point between Indianola and Kingston, is 930 feet (280 m). Puget Sound extends approximately 100 miles (160 km) from Deception Pass in the north to Olympia in the south. Water flow through Deception Pass is approximately equal to 2% of the total tidal exchange between Puget Sound and the Strait of Juan de Fuca. It is a complex estuarine system of interconnected marine waterways and basins, with one major and two minor connections to the open Pacific Ocean via the Strait of Juan de Fuca- Admiralty Inlet being the major connection and Deception Pass and Swinomish Channel being the minor. It is located along the northwestern coast of the U.S. Puget Sound ( / ˈ p juː dʒ ɪ t/ PEW-jit) is a sound of the Pacific Northwest, an inlet of the Pacific Ocean, and part of the Salish Sea.
