Puget Sound is a large body of water in the state of Washington. It is a complex estuarinesystem of interconnected marine waterways and basins connected to the Pacific Ocean through the Strait of Juan de Fuca. Puget Sound extends approximately 100 miles from the north where it meets the Strait of Juan de Fuca at Admiralty Inlet to Olympia, Washington in the south. However, the term "Puget Sound" is used not just for the body of water but also the general region centered on the sound. The PSHSC addresses its attention to the general region, to include all the navigable waters of Northwest Washington.
See the following Chapters of the United States Coast Pilot 7 for detailed discussions of the Puget Sound region to which the PSHSC gives its attention:
