Tyrma

The Tyrma rises in the Lesser Khingan and flows through the wooded mountains east of the Bureya. It is one of the Bureya's principal left-bank tributaries, a river some 334 kilometres long whose waters eventually join the Amur. Lenok, taimen and grayling live in its waters. The valley belongs to a network of rivers that drains the ranges between the Bureya and the lower Amur.
