== Construction ==
The reservoir was constructed between 1907 and 1914 by Neath Rural District Council for the supply of water. A temporary railway track was constructed for from the village of Penderyn to transport building materials to the dam site. Limestone was obtained from Penderyn Quarry and puddle clay was excavated from the glacial till at nearby Cilhepste Coed. Sandstone may have been sourced from Gwaun Hepste just east of Ystradfellte. The railway required the construction across the Afon Hepste of a long, high wooden viaduct.〔(Brecon Beacons National Park Authority )〕〔‘Reservoir Builders of South Wales’ (Dam Builders in the Age of Steam series book six) Bowtell H.D. & Hill G.〕
