Lake Washington Ship Canal : ウィキペディア英語版 | Lake Washington Ship Canal
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. ==History==
The ship canal project began in 1911 and was officially completed in 1934. Prior to construction of the Lake Washington Ship Canal, otherwise known as the Salmon Bay Waterway, water used to exit Lake Washington via the Black River which flowed from the south end of Lake Washington into the Duwamish River. As early as 1854, there was discussion of building a navigable connection between Lake Washington and Puget Sound for the purpose of transporting logs, milled lumber, and fishing vessels. Thirteen years later, the United States Navy endorsed a canal project, which included a plan for building a naval shipyard on Lake Washington. In 1891 the US Army Corps of Engineers started planning the project. Some preliminary work was begun in 1906, and work began in earnest five years later. The delays in canal planning and construction resulted in the U.S. Navy building the Puget Sound Naval Shipyard in Bremerton, Washington, which is located across the Sound from Seattle.
