Question: Cherokee Lake is a reservoir formed by theimpoundment of what river flowing from Kingsport to Knoxville, Tennessee?

full_context: Document 1: Clinch River: The Clinch River rises near Tazewell, Virginia, and flows southwest for more than 300 mi through the Great Appalachian Valley, gathering various tributaries, including the Powell River, before joining the Tennessee River in Kingston, Tennessee.
Document 2: Cherokee Lake: Cherokee Lake, also known as Cherokee Reservoir, is a reservoir in Tennessee formed by the impoundment of the Holston River behind Cherokee Dam.
Document 3: Hiwassee Dam: Hiwassee Dam is a hydroelectric dam on the Hiwassee River in Cherokee County, in the U.S. state of North Carolina. It is one of three dams on the river owned and operated by the Tennessee Valley Authority, which built the dam in the late 1930s to bring flood control and electricity to the region. The dam impounds the Hiwassee Lake of 6000 acre , and its tailwaters are part of Apalachia Lake. At 307 ft , Hiwassee Dam is the third highest dam in the TVA system, behind only Fontana and Watauga.
Document 4: Lake Keowee: Lake Keowee is a man–made reservoir in the United States in the state of South Carolina. It was created to serve the needs of a power utility (Duke Energy) as well as public recreational purposes. It is approximately 26 mi long, 3 mi wide, with an average depth of 54 ft , and a shoreline measured at 300 mi in total, and is approximately 800 ft above sea level. It began in 1971 as a massive demolition and building project, including the construction of two large dams––Keowee Dam and Little River Dam––and covered 18372 acre of the state. The lake collects or "impounds" waters from the Keowee River and the Little River and others, and the outflows below the respective dams join to form the Seneca River which flows into the larger Savannah River. Lake water helps to cool Duke Energy's three nuclear reactors located at the Oconee Nuclear Generating Station. In addition, the force of falling water through gravity helps generate hydroelectric power. The Keowee Hydro Station generates 158 megawatts from the lake's outflows. In addition, Lake Keowee has been touted as a recreational destination for fishing, boating, swimming, sailing, kayaking and other watersports, and the lake has been described as having pure and clean water. The name "Keowee" (ᎨᎣᏫ) is a Cherokee name roughly translated as "place of the mullberries." The former Keowee River, which was inundated by Lake Keowee, had been part of the Cherokee Lower Towns region, and Keowee Town had been located on the bank of the Keowee River.
Document 5: Holston Mountain: Holston Mountain is a mountain ridge in Upper East Tennessee and southwest Virginia, in the United States. It is in the Blue Ridge Mountains part of the Appalachian Mountains. Holston Mountain is a very prominent ridge-type mountain in Tennessee's Ridge and Valley Region, about 28 miles (45 km) long, running from southwest to northeast, covering about 268 square miles (694 km²). Its highest summit is "Holston High Point", on which a Federal Aviation Administration (FAA) aircraft navigational beacon is located, at an elevation of 4,280 feet (1,304.5 m) above mean sea level. The second highest point is "Rye Patch Knob", at 4,260 feet (1,298.5 m) above mean sea level. The third highest point is "Holston High Knob" where an old dismantled Cherokee National Forest fire tower (now a Communications Tower) marks the elevation at 4,136 feet (1,240.5 m) above mean sea level.
Document 6: Nickajack Dam: 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.
Document 7: Nolichucky River: The Nolichucky River is a 115 mi river that flows through Western North Carolina and East Tennessee, in the southeastern United States. Traversing the Pisgah National Forest and the Cherokee National Forest in the Blue Ridge Mountains, the river's watershed is home to some of the highest mountains in the Appalachians, including Mount Mitchell, the highest point in the eastern United States. The river is a tributary of the French Broad River, and is impounded by Nolichucky Dam near Greeneville, Tennessee.
Document 8: Holston River: The Holston River is a 136 mi river that flows from Kingsport, Tennessee, to Knoxville, Tennessee. Along with its three major forks (North Fork, Middle Fork and South Fork), it comprises a major river system that drains much of northeastern Tennessee, southwestern Virginia, and northwestern North Carolina. The Holston's confluence with the French Broad River at Knoxville marks the beginning of the Tennessee River.
Document 9: Nickajack Lake: 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.
Document 10: Norris Lake (Tennessee): Norris Lake is a reservoir that is located in Anderson, Campbell, Claiborne, Grainger, and Union counties in Tennessee. The lake was created by the Norris Dam at the Cove Creek Site on the Clinch River in 1936 by the TVA for flood control. The dam was the first major project taken on by the TVA. The lake, dam and the town of Norris, Tennessee are named after George W Norris, who was a United States senator from Nebraska and wrote the legislation that created the TVA.
Document 11: Cherokee Dam: Cherokee Dam is a hydroelectric dam located on the Holston River in Grainger County and Jefferson County, Tennessee, in the southeastern United States. The dam is operated and maintained by the Tennessee Valley Authority, which built the dam in the early 1940s to help meet urgent demands for energy at the outbreak of World War II. Cherokee Dam is 175 ft high and impounds the 28780 acre Cherokee Lake. It has a generating capacity of 135,200 kilowatts. The dam was named for the Cherokee, a Native American tribe that controlled much of East Tennessee when the first European settlers arrived in the mid-18th century.
Document 12: French Broad River: The French Broad River flows 218 mi from near the town of Rosman in Transylvania County, North Carolina, into the state of Tennessee. Its confluence with the Holston River at Knoxville is the beginning of the Tennessee River. The river flows through the counties of Transylvania, Buncombe, Henderson, and Madison in North Carolina, and Cocke, Jefferson, Sevier, and Knox in Tennessee, and drains large portions of the Pisgah National Forest and the Cherokee National Forest.
Document 13: Fort Patrick Henry Dam: Fort Patrick Henry Dam is a hydroelectric dam on the South Fork Holston River within the city of Kingsport, in Sullivan County in the U.S. state of Tennessee. It is the lowermost of three dams on the South Fork Holston owned and operated by the Tennessee Valley Authority, which built the dam in the early 1950s to take advantage of the hydroelectric potential created by the regulation of river flow with the completion of Watauga Dam, South Holston Dam, and Boone Dam (which were primarily flood control structures) further upstream in preceding years. The dam impounds the 872 acre Fort Patrick Henry Lake. While originally built for hydroelectric generation, the dam now plays an important role in the regulation of water flow and water temperature for the John Sevier Fossil Plant and other industrial plants downstream.
Document 14: Fontana Lake: Fontana Lake is a reservoir impounded by Fontana Dam on the Little Tennessee River located in Graham and Swain counties in North Carolina. The lake forms part of the southern border of Great Smoky Mountains National Park and the northern border of part of the Nantahala National Forest. Depending on water levels, the lake is about 17 mi long. The eastern end is the Tuckasegee River near Bryson City. It has an average depth of 135 ft and reaches a maximum depth of 440 ft , making it the deepest lake in North Carolina. The lake has many inlets into coves and many islands formed from former mountain peaks, especially near the eastern end. As with most dam-impounded lakes, the steep banks are exposed when water levels are low. Many towns were submerged shortly after the creation of Fontana Lake, such as Proctor and Judson.
Document 15: Cumberland River: The Cumberland River is a major waterway of the Southern United States. The 688 mi river drains almost 18000 mi2 of southern Kentucky and north-central Tennessee. The river flows generally west from a source in the Appalachian Mountains to its confluence with the Ohio River near Paducah, Kentucky, and the mouth of the Tennessee River. Major tributaries include the Obey, Caney Fork, Stones, and Red rivers.
