Urgal
The Urgal flows west from the spurs of the Bureya Range to join the Bureya from the left. Its 164-kilometre course drains a wooded mountain basin, receiving the Chegdomyn and other tributaries on its way. Beyond their confluence, the Bureya turns south towards the Amur. The river's name has been associated with the Evenki, whose language gave many of the waterways of this northern country their names.
