Nickajack Dam is one of nine dams on the Tennessee River owned and operated by which federally owned corporation in the United States created by congressional charter on May 18, 1933?
Tennessee Valley Authority The Tennessee Valley Authority (TVA) is a federally owned corporation in the United States created by congressional charter on May 18, 1933 to provide navigation, flood control, electricity generation, fertilizer manufacturing, and economic development to the Tennessee Valley, a region particularly affected by the Great Depression. The enterprise was a result of the efforts of Senator George W. Norris of Nebraska. TVA was envisioned not only as a provider, but also as a regional economic development agency that would use federal experts and electricity to rapidly modernize the region's economy and society.
Allegheny River Lock and Dam No. 4 The Allegheny River Lock and Dam No. 4 in Harrison Township, Allegheny County, Pennsylvania, is a lock that was built 1920-1927, and opened in 1927, 24.2 miles upstream from the mouth of the river in Pittsburgh. 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. It has a single lock and a fixed crest dam, keeping the river depth at least 9 feet in the pool above the dam. The amount of water that flows over the dam is not controlled locally, so it does not provide flood control, but it does help provide water to municipalities.
