In the late 1920s, Appalachian Power began purchasing land and planning for a hydroelectricity dam within the Smith Mountain Gorge that is split by the Roanoke River. After several delays and the completion of engineering studies, construction began in 1960. Construction on the smaller Leesville Dam also began downstream at this time as well. Concrete pouring began in 1961 and in 1962, the re-construction of roads and bridges that would be affected by the reservoir was complete.
Filling of the reservoir, Smith Mountain Lake, began fifty one years ago today on September 24, 1963. On March 7, 1966, the reservoir was full. In 2016, Smith Mountain Lake residents will celebrate FIFTY years of enjoying this beautiful lake.
