Beiarelva (also Storåga ) is a 56 km long river in the municipality of Beiarn in Fylke Nordland . The river has its origin in the upper Beiardalen in the Saltfjellet-Svartisen National Park . The river follows the main valley in Beiarn and flows into the Beiarfjord at Tvervik . Larger tributaries are Gråtåga and Arstadelva from the left and Tverråga , Tollåga , Store Gjeddåga from the right.

Salmon and sea ​​trout are caught in the Beiarelva . The river also has an arctic char population, which has been fully protected since 2008. The river has a salmon-carrying stretch of 27.5 km, from the mouth to Høgforsen near Tollå . Salmon are also found on a 3 km stretch of the Tollåga tributary and 0.6 km of the Store Gjeddåga tributary . In 1981 the salmon parasite Gyrodactylus salaris was found in the river. This resulted in a sharp decrease in the salmon population in the river during the 1980s. In 1989 salmon fishing was banned in the Beiarelva. The river was treated with Rotenone in 1994 . In 2001 the salmon parasite was no longer found in the river and salmon fishing was allowed again.
