Ya (river)

The Ya is a 38-kilometer (24 mi) river in the municipality of Tynset in Innlandet county, Norway.[1]

The river starts as the confluence of the Nordya (North Ya) and Storya (Big Ya) north of the Grøntjørnan farm. The Midtya (Middle Ya) is a higher tributary of the Nordya.[2] The largest source of the Ya is Falningsjøen (Lake Falning, elevation 850 meters or 2,790 feet) via the tributary Falninga; the lake is used as a reservoir for the Ulset Hydroelectric Power Station.[3] The river is a right tributary of the Orkla River, which it flows into from the east with its mouth at Yset near Norwegian National Road 3. Together with its tributaries, the Ya has a drainage area of 285 square kilometers (110 sq mi). The Ya river system runs through Forollhogna National Park and the Grøntjønnan Nature Reserve.
