Fort Patrick Henry
Fort Patrick Henry is a run-of-river reservoir, meaning that water is passed through the reservoir without being stored long-term. It has two hydroelectric generating units with a net dependable capacity of 41 megawatts.
Fort Patrick Henry Reservoir, on the South Fork Holston River in East Tennessee, extends 10 miles upstream from the dam to Boone Dam.
Fort Patrick Henry is named after the colonial fort, also known as Long Island Station, that was established nearby at the site of present-day Kingsport, Tennessee. The dam was built primarily for hydropower, but it is also used to regulate the flow of water downstream to ensure a reliable supply of water for local industry, and for cooling water at TVA’s John Sevier Fossil Plant.
Fort Patrick Henry Reservoir is a popular site for fishing, particularly rainbow trout, bluegill, bass and crappie. Warrior’s Path State Park is located on the reservoir.
