The Claerwen reservoir and dam in Powys, Wales, were the last additions to the Elan Valley Reservoirs system built to provide water for the increasing water demand of the city of Birmingham and the West Midlands. The dam is a gravity dam built mainly of concrete, with the exterior dam face is dressed stone. The dam is a gravity dam built upon solid rock foundations as the pressure of the reservoir behind should be in equilibrium with the total weight of the dam itself thus causing complete stability.
