Lluest-wen Reservoir was constructed in 1898, but came to national attention in 1969 when a major leak caused an evacuation of residents down-valley while emergency repair work was carried out. Back in 1929 the place set a maximum daily rainfall record for Wales, with 211mm of rain recorded. You have been warned!
