The Or (Russian: Орь, Kazakh: Ор) is a river in Orenburg Oblast of Russia and Aktobe Province of Kazakhstan. It is a left tributary of the Ural, and is 332 km long, with a drainage basin of 18 600 km2.[1] The river is formed by the confluence of the rivers Shiyli and Terisbutak,[2] which have their sources on the western slopes of the Mugodzhar Hills,[3] and it joins the Ural by the city of Orsk. Most of its discharge are from melting snow. The average discharge, 61 km from its mouth, is 21.3 m³/sek. The spring flooding lasts from April to mid-May. The rest of the year the waterlevel is very low. The river freezes in late October and is icebound until March - April. The river is used for irrigation and water supply.
