We often talk of Tryweryn but often forget the flooding of other valleys and villages to feed England with water. For example.. . the elan valley .. "In 1892, the British government passed the Birmingham Corporation Water Act allowing the council to effect compulsory purchase of the total water catchment area of the Elan and Claerwen valleys . 180 sqm of Wales was given to Birmingham to do what they wanted and it was nothing Wales couLd do about it The Act also gave Birmingham the powers to move more than 100 people living in the Elan Valley. All the buildings were demolished. Lake Vyrnwy Was built in the 1880s to supply Liverpool with water. Those that lived in the village of Llanwddyn and surrounding farms were forced to move before their homes were demolished and the area flooded As far as i know so far these lakes were built to supply England with water ..........
