Altaelva


Altaelva is the third-longest river in Troms og Finnmark county, Norway. The river begins in the mountains and lakes in Kautokeino Municipality, near the border with Troms og Finnmark county and Finland, just south of Reisa National Park. The long river then runs northward into Alta Municipality where it flows out into the Altafjorden in the town of Alta. The river has carved out Sautso, one of the largest canyons in Europe on its way from the high Finnmarksvidda plateau down to the sea. The villages of Kautokeino and Masi are located along the river, in addition to the town of Alta.
During the 1970s and 1980s, the river was the site of the Alta controversy regarding the construction of a hydroelectric power plant. The Alta power station was eventually built in 1987, creating the lake Virdnejávri on the river.
The river is one of the best salmon rivers in Norway, known for its large-sized salmon. In older days, salmon up to were recorded, and still fish up to are caught. In 2011, 1,082 salmon were caught on the river.

Name

The part of the river that is upstream of the Alta dam is also called Kautokeinoelva, meaning the "Kautokeino River", since that part of the river lies in Kautokeino. That part of the river is also known as Guovdageaineatnu or Eatnu in the Northern Sami language.
