Document Type: Proceeding Paper

Part of: Waterpower '89


The navigable portion of the river, extending northeast of Pittsburgh approximately sixty miles, contains eight lock and dam systems under the jurisdiction of the U.S. Army Corps of Engineers (COE). Hydroelectric plants at Allegheny Lock and Dam (ALD) Nos. 5 and 6 have been operating since late 1988 and construction is now well underway on plants at ALD 8&9. This paper serves as an overview of the development of these four projects, particularly the design and construction phases, and presents some insights to the water-to-wire process.
