Juklavatnet is a lake on the border of the municipalities of Kvinnherad and Jondal in Hordaland county, Norway. The 3.61-square-kilometre (1.39 sq mi) lake lies just outside of Folgefonna National Park and immediately to the west of the Nordre Folgefonnaglacier. The only road access comes from the small village of Nordrepollen in the Mauranger area of Kvinnherad municipality, about 10 kilometres (6.2 mi) south of the lake. There is a dam on the western end of the lake which regulates the depth of the water so that it can be used for hydroelectric power generation. The lake is the largest reservoir that feeds into the Mauranger power station.
