Bulgan River, which belongs to the Central Asian Basin, begins from Dushin Lake close to the state border line and flows into Ulungur Lake in China. The drainage basin of this river is 8750 sq km. The river runs through the high mountains of the Mongolian Altai Range with the river valley ranging from 0.3-0.5 km wide.
The valley becomes wider from the junction of Bulgan River and Bayan River though, which flows into the former river. In the valley and around this area, there are many small glacial lakes. Apart from the bigger Uliastai, Bayan and Turgen rivers, the Ulaan, Yolt, Ikh Jargalan, Khujirt, Tsunkhul and Ikh Tumurt rivers join to Bulgan River. The river has much stronger streams and rapids up until the junction with the Bayan River, but it becomes much quieter and wider (10-60 m) by the end. On average, the river is 0.5 m to 1.5 m deep, but can go as deep as 4 to 5 m in places.
The River freezes at the end of October and melts in April. The river is home to the beaver, which is registered in Mongolian Red Book. Some parts of the River, where beavers actually inhabit, has been made into a strictly protected area for beavers since 1965. The protected area is in Bulgan soum, Khovd Province.
The status of the protected area was changed in 1995 and it became a Biology Reserve Area for protecting animals. Beavers live in a hole with two entrances. One is on dry land while the other is in the river. Bulgan river is home to various kinds of fish like perches, breams and carps, as well as many migratory birds. There is a mineral water spring around the junction of Bulgan River and Indert River. The mineral spring is used for healing one’s internal organs, joint problems and headache. 80000 ha area around Bulgan River and Ikh Ongog has been protected as National park since 2011 according to decree number 18 of State Great Khural of Mongolia.
