Sutara

The Sutara flows through wooded hills of the Lesser Khingan, among birch and cedar forests. It joins the Kuldur to form the Bira, a left-bank tributary of the Amur. Mountain streams add their waters along its winding course, and rain, snowmelt and groundwater feed the river through the seasons. Lenok, grayling and taimen inhabit its waters, alongside fish of the wider Amur basin.
