Appalachian Power, operator of the Smith Mountain Project hydroelectric facility in southwest Virginia, is advising property owners and visitors that the Smith Mountain Reservoir will exceed its full pond level by one foot Thursday morning.

This is the third time in about two months that the lake would exceed full pond. The lake exceeded it's full capacity on April 13 and May 22.

Normal full pond level at Smith Mountain Lake is 795 feet. The project’s lower reservoir, Leesville Lake, has a full pond level of 613 feet.

Based on updated river predictions from the National Weather Service, Smith Mountain reservoir will reach an elevation of 796 feet, or one foot above full pond. Allowing the reservoir to exceed full pond will assist in preventing additional flooding downstream.

Shoreline property owners are urged to be attentive to local and National Weather Service reports and to make sure that property around the lake is secure.

An increase of only inches in water levels could make walking docks unsafe, cause unsecure water craft and floating docks to float away into navigation channels and wash loose items from the shore. Property owners are encouraged to relocate any unsecured items from the lower levels of their docks and watch for floating hazards such as natural debris.

Current lake levels and inflow/discharge information is available anytime at www.aep.com/recreation/hydro. The project website is www.SmithMountainProject.com.

Smith Mountain Project is a 636-megawatt pumped storage hydroelectric facility on the Roanoke River that utilizes an upper reservoir (Smith Mountain Lake) and a lower reservoir (Leesville Lake). Combined, the project includes about 600 miles of shoreline.

Water stored in Smith Mountain Lake first passes through turbine-generators in the powerhouse to produce electricity and is discharged into Leesville Lake. From there some water is released through the Leesville Dam or pumped back into Smith Mountain. The project is operated by Appalachian Power.
