Primorsky District
The source of the Kodina is in the swamps in the southern part of Primorsky District, about a dozen kilometers southeast of Lake Voyozero (which belongs to the Northern Dvina basin, not to the Onega Basin). The river flows in the southern direction, enters Onezhsky District and turns southwest. It is populated downstream from the selo of Kodino. The mouth of the Kodina is in the place where the Onega is separated into two streams (the Kodina empties into the eastern one), downstream from the village of Antsiferovsky Bor.
