| River system | Otra |
The Otra is 245 kilometres (152 mi) long, making it Norway's eighth-longest river. There are many large lakes along the river including: Åraksfjorden, Byglandsfjorden, Hartevatnet, and Kilefjorden. There are 12 hydroelectric power plants built along the river, which produce much of the electricity for the southern part of Norway.[1]
The salmon do well in the Otra river because the water is not too acidic. The calcareous rocks in the catchment area at the northern end of the Setesdal valley give the water a certain buffer capacity against acidification.[2]
