Watauga (rivière)
Résumé
The Watauga River (wəˈtɔːgə) is a large stream of western North Carolina and East Tennessee. It is long with its headwaters in Linville Gap to the South Fork Holston River at Boone Lake.
The Watauga River rises from a spring located south to the base of Peak Mountain at Linville Gap in Avery County, North Carolina. The spring emanates from the western side of the Tennessee Valley Divide, which is, at this location, congruent with the Eastern Continental Divide. On the other side of the divides at Linville Gap are the headwaters of the Linville River in the Upper Catawba Watershed. Waters of the Linville River eventually reach the Atlantic Ocean, whereas waters of the Watauga River reach the Gulf of Mexico; hence the Eastern Continental Divide. The river then flows across Watauga County, North Carolina crossing the Tennessee state line (River Mile (RM) 55.1) at Johnson County, then into Carter County, Tennessee and ends at its confluence with the Holston River's South Fork (RM 0) on the Washington/Sullivan County border.
After crossing into Johnson County, the Watauga River is first impounded by the Tennessee Valley Authority (TVA) Watauga Dam, creating the Watauga Lake. This impoundment receives two important tributaries: the Elk River, and Roan Creek. Watauga Lake is bridged by Tennessee State Route 67 over Butler Memorial Bridge just as the watercourse enters Carter County, Tennessee. The Appalachian Trail crosses the river on Watauga Dam.
Nearly 3 miles below Watauga Dam, on the Horseshoe section of the Watauga River, is the TVA Wilbur Dam, which forms a much smaller but very deep reservoir known as Wilbur Lake. TVA releases approximately of discharged water back into the Watauga River during the summer months.
Below Wilbur Dam the river flows generally north and then west into Carter County where it forms the northern limits of Elizabethton, where the Watauga then receives the Doe River. Farther downstream on the Watauga River at the boundary between Carter County and Washington County is the old TVA Watauga Steam Plant.
