A remarkable document that details the plans to connect Lake Washington via Lake Union to Puget Sound. This is an enormous lithographed map on two joined sheets, as issued. The main map shows the planed canal and locks between Union Bay, Lake Union, Salmon Bay, and on to Puget Sound at Shilshole Bay. Of historical interest is the second proposed canal from Salmon Bay to Smith's Cove on the sound; a route that was not built. With a large inset map of the Seattle metropolitan area. Profiles along bottom detail the elevation changes and required locks for the Smith's Cove to Salmon Bay canal, and the Shilshole Bay to Lake Washington canal. The canal was first suggested by Thomas Mercer in 1854. After the failure of several private efforts, in 1917 the U.S. Army Corps of Engineers under Gen. Hiram M. Chittenden began construction.
