Snoqualmie Falls Hydroelectric Project, .5 mile north of Snoqualmie, Snoqualmie, King County, WA
Summary
Significance: The Snoqualmie Falls Hydroelectric Project was completed in 1898 and includes a cavity generating station, constructed some 250 feet below the surface of the river and about 300 feet from the edge of the falls. It is one of the few cavity plants in the United States and one of possibly two in the nation that contains its turbines, generators, and operators controls all within the cavity. Thomas T. Johnston, a consulting engineer from Chicago, executed the design and Charles Baker, president and chief engineer of the Snoqualmie Falls Power Company, oversaw the design and construction of the project. The Snoqualmie Falls cavity plant is a national civil engineering landmark.
