Holston River
The Holston River is a 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.
The North Fork flows southwest from Sharon Springs in Bland County, Virginia. The Middle Fork flows from near the western border of Wythe County, Virginia, joining the South Fork in Washington County, Virginia, southeast of Abingdon. The South Fork rises near Sugar Grove in Smyth County and flows southwest to join the North Fork at Kingsport.〔(【引用サイトリンク】title=Holston River - South Fork )〕 The Watauga River, a tributary of the South Fork Holston, flows westward from Watauga County, North Carolina.
The main stem of the Holston is impounded by the Tennessee Valley Authority's Cherokee Dam near Jefferson City, Tennessee. Five other dams, also managed by TVA, impound the Holston's headwater streams: Watauga Dam and Wilbur Dam on the Watauga River, and Boone Dam, Fort Patrick Henry Dam, and South Holston Dam, on the South Fork Holston River.
== Power generation ==
The Holston River valley has been greatly developed for electrical power generation, both with hydroelectric dams and coal-fired steam plants. In the upper reaches, some of these plants are controlled by private interests; in the downstream portion, they are owned by the United States Government's Tennessee Valley Authority.
