Elan Valley Reservoirs, Chain of reservoirs in Mid Wales
The Elan Valley contains five main reservoirs created by damming the Elan and Claerwen rivers, spanning across the Welsh countryside.
Construction of the reservoirs began in 1893 to provide clean water to Birmingham after disease outbreaks from contaminated water supplies.
The Elan Valley Estate preserves 72 square miles of land with designated Sites of Special Scientific Interest containing diverse plant and animal species.
Visitors access the reservoirs through the B4518 road from Rhayader, leading to the Elan Valley Visitor Centre with parking facilities.
The Nant-y-Gro dam within the complex served as a testing ground for bouncing bomb experiments during World War II.
