Haweswater

Haweswater is a reservoir in the Lake District, built in the valley of Mardale. The controversial construction of the Haweswater dam started in 1929, after Parliament passed an Act giving the Manchester Corporation permission to build the reservoir to supply water for Manchester. The decision caused public outcry, since the farming villages of Measand and Mardale Green would be flooded, with their inhabitants needing to be relocated

Originally, Haweswater was a natural lake about four kilometres long, nearly divided by a tongue of land at Measand; the two reaches of the lake were known as High Water and Low Water. The building of the dam raised the water level by 29 metres (95 feet) and created a reservoir six kilometres (four miles) long and around 600 metres (almost half a mile) wide.
