    a river in Aktiubinsk Oblast, Kazakh SSR, and in Orenburg Oblast, RSFSR. A left tributary of the Ural River, the Or’ is 332 km long and drains an area of 18,600 sq km. It is formed by the confluence of the Shiili and Terisbutak rivers, which rise on the western slopes of the Mugodzhar Mountains. The river is fed primarily by snow. The mean flow rate 61 km from the mouth is 21.3 cu m per sec. High water lasts from April to mid-May; during the rest of the year the river is extremely shallow. It freezes during the second half of October or in November and thaws at the end of March or in April. The waters of the Or’ are used for basin irrigation and for water supply. The city of Orsk is located at the point where the Or’ empties into the Ural River.
