Informations supplémentaires:
Originally, Haweswater was a natural lake about four kilometres long, almost divided in two 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. The dam wall measures 470 metres long and 27.5 metres high; at the time of construction it was considered to be cutting-edge technology as it was the first hollow buttress dam in the world, being constructed using 44 separate buttressed units joined by flexible joints. There is a parapet, 1.4 metres (56 inches) wide, running the length of the dam and from this, tunnelled supplies can be seen entering the reservoir from the adjoining valleys of Heltondale and Swindale. When the reservoir is full, it holds 84 billion litres (18.6 billion gallons) of water. The reservoir is now owned by United Utilities plc. and delivers water to Manchester.
