The Terek River (Russian:Те́рек;IPA: [ˈtʲerʲɪk]; Karachay-Balkar:Terk; Georgian:თერგი, Tergi; Ossetian:Терк, Terk; Avar:Терек, Terek; Chechen:Теркa, Terka) is a major river in the Northern Caucasus, flowing through Georgia and Russia into the Caspian Sea. It rises in Georgia near the juncture of the The Greater Caucasus Mountain Range and the Khokh Range, to the southwest of Mount Kazbek, winding north in a white torrent between the town of Stepantsminda and the village of Gergeti toward the Russian region North Ossetia and the city of Vladikavkaz. It turns east to flow through Chechnya and Dagestan before dividing into two branches which empty into the Caspian Sea. Below the city of Kizlyar it forms a swampy river delta around 100 kilometres (62 mi) wide. The river is a key natural asset in the region, being used for irrigation and hydroelectric power in its upper reaches.
