Orkla (river)

Orkla is a river in Trøndelag and Innlandet counties in Norway. At 180 kilometres (110 mi) in length, it is the longest river in Trøndelag county. The river follows the Orkdalen valley, discharging into the Orkdal Fjord, an arm of the large Trondheimsfjorden, at the town of Orkanger. The river originates in the lake Orkelsjøen, a small lake (2.2 km2 (0.85 sq mi)) near the watershed with the river Unna in the Glomma river system, in Oppdal Municipality in the Dovrefjell mountains. The river runs through Oppdal Municipality, Tynset Municipality, Rennebu Municipality, and Orkland Municipality. The municipalities are all in Trøndelag county, except for Tynset Municipality, which is in Innlandet county. Major towns and villages along the river include: Orkanger, Fannrem, Vormstad, Svorkmo, Storås, Meldal, Å (in Orkland Municipality); and Voll and Berkåk (in Rennebu Municipality). Orkla is a popular river for salmon fishing and the fourth largest in Norway by volume. About an 88-kilometre (55 mi) long stretch of the river through Orkland Municipality and Rennebu Municipality is used for salmon fishing throughout the season which typically runs from 1 June through 31 August.
