Suluk
The Suluk begins in a mountain lake of the same name on the slopes of the Bureya Range. This swift river runs through the uplands before meeting the Ayakit; together they form the Amgun, a great tributary of the lower Amur. Lenok, char and sculpin inhabit the cold waters near its source. The river's course belongs to a mountain watershed separating the Amgun from the Bureya basin to the west.
