The Bambuyka (Russian: Бамбуйка) is a river in Buryatia, southern East Siberia, Russia. It is long, and has a drainage basin of .
The only inhabited place in the area is Bambuyka, Muysky District, a small hamlet located close to the mouth of the river.[1]
The Bambuyka is a left tributary of the Vitim. Its sources are in a small lake close to the southwestern slope of Muisky Gigant, the highest peak of the Southern Muya Range. The river flows first in a SSE direction across mountainous terrain.[1] It bends east close to the east of a sharp bend of the Tsipa and flows roughly in an eastward direction. Then it bends again and flows southeastwards. In its lower course it bends gradually, meandering northeastwards in a floodplain, until it finally meets the left bank of the Vitim 812km (505miles) from its mouth in the Lena.[2]
The longest tributaries of the Bambuyka are the long Bambukoy on the left, as well as the long Pashkov-Klyuch and the long Golyube on the right.
