Cumbria - Haweswater Reservoir, Lake District.
In 1929 work started on raising the level of the original natural lake. The dam was completed in 1935 and this lake now provides 25% of the water needed in the greater Manchester area.
The plans caused controversy because the villages of Measand and Mardale Green were flooded and when the lake is at a low level remains of some of the original buildings can still be seen.
The dam was the world's first hollow butress dam and was a major engineering achievement for the time. Hawes derives from old English or old Norse and means water.
There is a of population of Schelly fish dating from the Ice Age living in the lake.
