Question: 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?
Context: Nickajack Lake is the reservoir created by Nickajack Dam as part of the Tennessee Valley Authority.  The lake stretches from Nickajack Dam to Chickamauga Dam, passing through the city of Chattanooga.  The stretch of the Tennessee River commonly referred to as the "Grand Canyon of Tennessee" also is part of Nickajack Lake. Kentucky Dam is a hydroelectric dam on the Tennessee River on the county line between Livingston and Marshall counties in the U.S. state of Kentucky.  The dam is the lowermost of nine dams on the river owned and operated by the Tennessee Valley Authority, which built the dam in the late 1930s and early 1940s to improve navigation on the lower part of the river and reduce flooding on the lower Ohio and Mississippi rivers.  It was a major project initiated during the New Deal of President Franklin D. Roosevelt's administration, to invest in infrastructure to benefit the country.  The dam impounds the Kentucky Lake of 160000 acre , which is the largest of TVA's reservoirs and the largest artificial lake by area in the Eastern United States. Pickwick Landing Dam is a hydroelectric dam on the Tennessee River in Hardin County, in the U.S. state of Tennessee.  The dam is one of nine dams on the river owned and operated by the Tennessee Valley Authority, which built the dam in the 1930s as part of a New Deal-era initiative to create a continuous navigation channel between the river's mouth and Knoxville, and bring economic development to the area.  The dam impounds the 43100 acre Pickwick Lake and its tailwaters are part of Kentucky Lake. 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. Guntersville Dam is a hydroelectric dam on the Tennessee River in Marshall County, in the U.S. state of Alabama.  It is one of nine dams on the river 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 create a continuous navigation channel on the entire length of the river and bring flood control and economic development to the region.  The dam impounds the Guntersville Lake of 67900 acre , and its tailwaters feed into Wheeler Lake. The Tennessee River Blueway is a 50 mi section of the Tennessee River that flows between the Chickamauga Dam and the Nickajack Dam and through downtown Chattanooga, Tennessee and the Tennessee River Gorge.  The city of Chattanooga and the Tennessee River Gorge Trust along with other agencies have designated the section of river as a blueway for a canoe and kayak paddlers to travel and enjoy.  Along the way, travelers will find primitive camping areas next to the river, a vibrant mix of museums, restaurants, activities, entertainment and natural attractions. Nickajack Cave is a large, partially flooded cave in Marion County, Tennessee.  It was partially flooded by the Tennessee Valley Authority's Nickajack Lake, created by the construction of Nickajack Dam in 1967.  The entrance was originally 140 feet wide and 50 feet high.  There is now about 25–30 feet of water at the entrance, so the portion of the entrance above water is 140 feet wide and 20–25 feet high.  It houses a large colony of Gray Bats, an endangered species, and the water levels have posed a danger to the bat colony.  The cave took its name from the Chickamauga Cherokee town of Nicojack/Nickajack, located between its mouth and the Tennessee River.  The town was destroyed once in 1794 by the Nickajack Expedition. Nickajack Dam is a hydroelectric dam in Marion County in the U.S. state of Tennessee.  It is one of nine dams on the Tennessee River owned and operated by the Tennessee Valley Authority, which built the dam in the mid-1960s to replace the outdated Hales Bar Dam 6 mi upstream.  The dam impounds the 10370 acre Nickajack Lake and feeds into Guntersville Lake.  Nickajack Dam is named for a Cherokee village once located just upstream from the dam (the site is now submerged).  The village was the namesake for Nickajack Cave, which was partially flooded by the reservoir. Watts Bar Dam is a hydroelectric dam on the Tennessee River in Meigs and Rhea counties in Tennessee, United States.  The dam is one of nine dams on the main Tennessee River channel operated by the Tennessee Valley Authority, which built the dam in the early 1940s to provide flood control and electricity and to help create a continuous navigable channel along the entire length of the river.  The dam is the technical boundary between the 39090 acre Watts Bar Lake— which it impounds— and Chickamauga Lake, which stretches from the dam's tailwaters southward to Chattanooga. Wheeler Dam is a hydroelectric dam on the Tennessee River between Lauderdale County and Lawrence County in the U.S. state of Alabama.  It is one of nine dams on the river owned and operated by the Tennessee Valley Authority, which built the dam in the mid-1930s as part of a New Deal-era initiative to improve navigation on the river and bring flood control and economic development to the region.  The dam impounds the Wheeler Lake of 67070 acre and its tailwaters feed into Wilson Lake.
