Mardale Head, Haweswater Reservoir in the Lake District, Cumbria.
In 1919, the people of Mardale Green learnt that Manchester Water Corporation had just secured the long awaited Haweswater Act, a compulsory purchase agreement of the day, which granted them permission to build a dam and drown the hamlet. In dry weather, when the water level of the reservoir is very low, the remains of walls from the abandoned hamlet can be seen.
