Møsvatn
Lake in Telemark, Norway
Møsvatn or Møsvann is a lake in Vinje Municipality in Telemark county, Norway. It is the tenth-largest lake in Norway with a surface area of 79.1 square kilometres (30.5 sq mi) and a volume of 1,573,523,000 cubic metres (1,275,676 acre⋅ft). The lake lies just east of the Hardangervidda National Park, in Skien watershed (Skiensvassdrag) catchment area. The lake discharges into the Måna river at a dam located on the Vinje-Tinn municipal border (so a very small part of the lake crosses into Tinn Municipality too). The lake has an irregular shape with three arms. The longest length across the lake is about 40 kilometres (25 mi). Møsvatn is a shallow mountain lake by Norwegian standards, reaching a maximum depth of 68.5 metres (225 ft).[1][2]
From 1904 to 1906 dam was constructed and the lake was filled to begin hydroelectric power production. The lake's surface now sits at an elevation of about 919 metres (3,015 ft) above sea level with the dam on the southeast end of the lake regulating the water level. Møsvatn is Norway's fourth largest hydroelectric power reservoir with an energy content corresponding to approximately 2,300 gigawatt-hours (8,300 TJ).[2]
