Geography
The district occupies the lower course of the
Onega River and the
White Sea coast around the
Onega Bay, including the western part of the
Onega Peninsula (which it shares with
Primorsky District). The waters of the district drain into the Onega and the short rivers of the Onega Bay basin. The main
tributaries of the Onega within the district limits are the
Kodina and the Kozha Rivers. The exception is the southwestern part of the district which lies in the basin of the
Ileksa River, a tributary of
Lake Vodlozero, in the
Baltic Sea basin. The divide between the Arctic and Atlantic Oceans thus runs through the district. There are many lakes throughout the district; the biggest one being
Lake Kozhozero, the source of the Kozha, a left tributary of the Onega. The islands in the Onega Bay are also administered by Onezhsky District. The biggest island of the Onega Bay is
Kiy Island.
