The Claerwen reservoir is the highest of the Elan Valley lakes and was the last to be completed. Outflow water runs along the valley to feed the Caban Coch reservoir, further down. The dam took six years to complete and was opened by Queen Elizabeth in 1952. It was designed in a Victorian style to blend in with the other dams in the Elan Valley. This viewpoint is looking up the valley in the direction of the dam. The expanse of upland between Rhayader and Pontrhydfendigaid is a designated National Nature Reserve.
