Description 

Allegheny River Lock and Dam No. 8 is a historic lock and dam complex located at Boggs and Washington Townships in Armstrong County. It was built between 1929 and 1931 by the United States Army Corps of Engineers, and consists of the lock, dam, esplanade, and operations building. The lock measures 56 feet by 360 feet, and has a lift of 17.8 feet. The dam measures approximately 50 feet high and 916 feet long; a three-foot addition was built on top of the dam in 1937. The operations building, or powerhouse, is a utilitarian two-story building in a vernacular early-20th century revival style. The lock and dam were built by the U.S. Army Corps of Engineers as a part of an extensive system of locks and dams to improve navigation along the Allegheny River. - Wikipedia
