Virvassåga /Virvasselva

Virvasselva or Virvassåga (Norwegian), Vijriesjohke (Southern Sami), or Viresjåhkå (Lule Sami) is a river in Rana Municipality in Nordland county, Norway. The river flows out of the eastern part of the lake Virvatnet. The stream Boneselva meets Virvasselva about 1 kilometre (0.62 mi) east of the lake Virvatnet. This is a large, continuous, very rich and untouched wetland area with tarns, rivers, marshes, and very tight vegetation. Virvasselva has a good population of Arctic char.
After about 5 kilometres (3.1 mi), the river Virvasselva reaches a pumping station where most of the water is diverted through a tunnel to flow west to supply the Rana power station. The much smaller river then continues north and meets the main river Ranelva at Elvmøtheia in the Dunderland Valley.
