Botnedalsvatn is a lake in Tokke Municipality in Telemark county, Norway. The 3.12km2 lake is located in the Botnedalen valley, about to the northwest of the village of Dalen. Botnedalsvatn has a dam on the southeast end of the lake which regulates the surface elevation of the lake. The lake is used as a reservoir for the nearby Byrte Hydroelectric Power Station. Water flows from this lake through a tunnel into the power plant which is located at the southern end of the nearby lake Byrtevatn.[2] [3]
