Byrtevatn is a lake in Tokke Municipality in Telemark county, Norway. The 4.8km2 lake is located about northwest of the village of Dalen. The main natural influx comes from the river Byrteåi. Byrtevatn has a dam on the south end of the lake which regulates the surface elevation of the lake. Water from the nearby lake Botnedalsvatn flows through a tunnel into the Byrte Hydroelectric Power Station and the water is then released into this lake.[2] [3]
