Description
The Holston River is a 136-mile (219 km) 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.
