Iro
(or Ero-Gol), a river in the People’s Republic of Mongolia; a right-bank tributary of the Orkhon (Selenga Basin) and its largest tributary. Length, 323 km. Basin area, approximately 12,000 sq km. It rises in the Khentei Mountains. In its upper course it flows through a narrow, wooded valley; in the Iro’s lower course the valley widens, and the river divides into branches. Owing to the rain there are freshets in the summer, during which the Iro carries large quantities of suspended sediments. From November through April it is icebound. The river is used for floating timber.
