Lake Vyrnwy
  A new Welsh lake for Liverpool's water  

Lake Vyrnwy was created by the Victorians when they built the first large masonry dam in Britain between 1881 and 1888.

A new water supply was urgently needed for the growing city of Liverpool, and the pure water of the Welsh mountains was to be carried by an aqueduct to the city.

The village of Llanwddyn, seen in this picture, was lost underwater when the dam, visible in the background, was brought into use to block the River Vyrnwy.
