Øvrevatnet or Øvervatnet is a meromictic lake (contains anoxic seawater at 40 metres deep, and further down) that lies in, Fauske Municipality in Nordland county, Norway. The lake lies about 6 km (3.7 mi) east of the town of Fauske. Its water is fresh just down to 10–15 m (33–49 ft). From that level the water gets more salty. Øvrevatnet is also much polluted by mining industry operations upstream in earlier times. The 11-square-kilometre (4.2 sq mi) lake flows out into the neighboring lake Nedrevatnet to the west.^[1]
