ROANOKE, Va. -- Appalachian Power wants boaters, kayakers, tubers, and other recreational users downstream of Claytor and Leesville dams to know water levels on the New and Roanoke rivers could rise rapidly starting Tuesday, June 14, and continue to fluctuate throughout the week.

The National Weather Service is calling for high temperatures this week and PJM, the independent regional transmission organization that manages the electric grid in 13 states, has notified Appalachian Power it may need to increase power generation at its hydroelectric plants to maintain the reliability of the regional electric grid if called upon to do so.

Below Claytor Dam, water levels could increase up to two feet in a matter of minutes. Water levels below Leesville Dam could increase as much as eight feet over a seven-hour period. Those considering recreating on the rivers should monitor AEP’s website for additional information and follow us on Smith Mountain or Claytor Facebook pages for updates.

Located on the New River in Pulaski County, the Claytor Dam is operated by Appalachian Power. The total installed electric generating capacity of the plant is 76 megawatts. Leesville Dam, with a generating capacity of 50 megawatts, is part of the Smith Mountain Project, a 636-megawatt pumped storage hydroelectric facility on the Roanoke River.
