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).

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]

Name

The Old Norse form of the name was just Ork (still found in the names Orkanger, Orkdal, Orkland) and Orkelsjøen. The meaning of the name is unknown (maybe derived from the old norse verb orka which means "to work" - the meaning of the name would then be "the river that works its way forward"). The name Orkla (with the diminutive ending -la) originally belonged to the uppermost part of the river (lying in Tynset, Innlandet), and the meaning of this name is probably "the small part of Ork".[1]
