Long Lake Hydroelectric Plant, Spanning Spokane River, Ford, Stevens County, WA

Significance: The Long Lake hydroelectric facility is significant as one of the earliest and, for many years, largest hydroelectric generating facilities in The Washington Water Power Company's electrical power generating network. It is the largest hydroelectric facility on the Spokane River. Its construction played a vital role in facilitating the urban, industrial, and agricultural development of eastern Washington and northern Idaho. The Long Lake Dam possesses engineering significance as a reflection of advanced hydroelectric technology of the early twentieth century. It is architecturally important for the imposing Romanesque Revival style of its power house. The Long Lake Hydroelectric Plant and its setting have remained largely unaltered since original construction of the facility in 1915. The historic property was nominated to the National Register of Historic Places in 1988. Constituent elements include the spillway dam, control dam (intake), cut-off (arch dam), and the four brick operating houses situated on top of the spillway dam.
