J. Percy Priest Dam is a dam in north central Tennessee at river mile 6.8 of the Stones River, a tributary of the Cumberland. It is located about ten miles east of downtown Nashville. The reservoir behind the dam is Percy Priest Lake. It is one of four major flood control reservoirs for the Cumberland; the others being Wolf Creek Dam, Dale Hollow Dam, and Center Hill Dam. The Flood Control Act of 1946 commissioned the construction of a project under the name “Stewarts Ferry Reservoir”.
