caption_attribution_description: Generator hall of the powerhouse, Chickamauga Dam, Tennessee, USA Original caption: The dam, located near Chattanooga, 471 miles above the mouth of the Tennessee River, has an authorized power installation of 81,000 kw., which can be increased to a possible ultimate of 108,000 kw. The reservoir at the dam adds 377,000 acre-feet of water to controlled storage on the Tennessee River system. The power that goes out over its 154,000 volt transmission line serves many useful domestic, agricultural and industrial uses.
context_page_description: The Chickamauga Dam is a hydroelectric dam on the Tennessee River in Chattanooga, Tennessee, United States. The dam is owned and operated by the Tennessee Valley Authority, which built the dam in the late 1930s as part of a New Deal era initiative to improve navigation and bring flood control and economic development to the Tennessee Valley. The dam impounds the 36,240-acre Chickamauga Lake and feeds into Nickajack Lake. The dam and associated infrastructure were listed on the National Register of Historic Places in 2017.
  Chickamauga Dam is named for the Chickamaugas, a politically detached branch of the Cherokee whose chief village was located just north of the dam site during the 18th century. The tribe's name has also been applied to several streams in the Chattanooga area, as well as an important American Civil War battle and a sandbar that existed at the dam site prior to its construction.
context_section_description: Chickamauga Dam is a concrete gravity-type dam 5,800 feet (1,800 m) long and 129 feet (39 m) high. Its hydroelectric generating capacity is 119 megawatts.  The dam has 18 spillway bays with a combined discharge of 470,000 cubic feet per second (13,000 m³/s).
  A 60-by-360-foot (18 by 110 m) navigation lock allows barges and other boats to travel past the dam, raising or lowering vessels 53 feet (16 m) between Chickamauga and Nickajack reservoirs.
