Editor's Notes
Pontsticill Reservoir (Welsh: Cronfa Pontsticill) or Taf Fechan Reservoir is a large reservoir on the Taf Fechan lying partly in the county of Powys and partly within the county borough of Merthyr Tydfil in south Wales. It lies within the Brecon Beacons National Park and Fforest Fawr Geopark.
The 110 ft high embankment has, since its completion in 1927, been holding back 15,400 megalitres of water for supply to industry and population to the south.
