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.[1]

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 the municipality of Oppdal in the Dovrefjell mountains. The river runs through the municipalities of Oppdal, Tynset, Rennebu, and Orkland. The municipalities are all in Trøndelag county, except for Tynset, which is in Innlandet county. Major towns and villages along the river include: Orkanger, Fannrem, Vormstad, Svorkmo, Storås, Meldal, Å (in Orkland); and Voll and Berkåk (in Rennebu).[citation needed]

Orkla is a popular river for salmon fishing and the fourth largest in Norway by volume.[1] About an 88-kilometre (55 mi) long stretch of the river through Orkdal, Meldal, and Rennebu is used for salmon fishing throughout the season which typically runs from 1 June through 31 August.[2]

The river is regulated by five power generation reservoirs, which were built between 1978 and 1985. The reservoirs have been a successful method of flood control preventing the river's major seasonal flooding.[1] The decommissioned Eidsfossen Power Station stands along the river south of the confluence with the Ya River at Yset.[3]
