Røsvatnet (Norwegian) or Reevhtse (Southern Sami) is a lake and reservoir in Hattfjelldal Municipality and Hemnes Municipality in Nordland county, Norway. It has been the site of human occupation since the Stone Age. Its area of 219 square kilometres (85 sq mi) makes it the second largest lake in Norway by surface area. Without the dam which has regulated the lake since 1957, it would be 190 square kilometres (73 sq mi) and the third largest lake in Norway. Its depth is 240 metres (790 ft), its volume is estimated at 15 cubic kilometres (3.6 cu mi), and its surface elevation is 374 metres (1,227 ft) above sea level.
