URPoint Details
Llyn Celyn is a large reservoir constructed between 1960 and 1965 in the valley of the River Tryweryn. It measures roughly 2½ miles long by a mile wide, and has a maximum depth of 140 ft (43 m). It has the capacity to hold 71,200 megalitres of water.
It was originally to be named Llyn Tryweryn Mawr (meaning "Great Tryweryn Lake"), but in September 1964 Liverpool Corporation agreed to the name change following a letter by the Tryweryn Defence Committee.
Construction of the reservoir involved flooding the village of Capel Celyn and adjacent farmland, a deeply controversial move. Much of the opposition was brought about because the village was a stronghold of Welsh culture and the Welsh language, whilst the reservoir was being built to supply Liverpool and parts of the Wirral peninsula with water, rather than Wales.
