Ural River, YUR uhl, is a shallow river that rises in the southern Ural Mountains in Russia. The Ural flows south from Russia through Kazakstan for about 1,570 miles (2,527 kilometers) and enters the Caspian Sea through several mouths. Salmon and sturgeon fisheries are along the Ural. Railroads cross it at Orenburg and Oral. Magnitogorsk, a major steel center of Russia, lies on the upper Ural.
