Eröö

The Eröö River flows through the forest and steppe of northern Mongolia before joining the Orkhon, a tributary of the Selenga. Rising in the Khentii Mountains, its waters pass through wooded uplands and valleys on their way west. The river belongs to a network of waterways that carries water from the Mongolian plateau northwards towards Lake Baikal, linking the country of the Khentii with the wider Selenga basin.
