The Swir ( Russian Свирь , Finnish and Karelian Syväri ) is a river in Leningrad Oblast in northwestern Russia . It begins at Vosnessenje ( Вознесенье , in the south of Lake Onega) and flows into Lake Ladoga after 224 km. The Swir connects the two largest lakes in Europe, Lake Onega and Lake Ladoga . It is also part of the White Sea-Baltic Sea Canal and the Volga-Baltic Sea Canal . Two river power plants use the height difference of 28.5 m and divide the river into the Upper Swir (93 km), Middle Swir (45 km) and Lower Swir (80 km).
The width is only 100 meters near the town of Podporoshje , which makes it difficult for the many ships to cross. In the flooded Iwinsk Basin ( Ивинский Разлив ) it reaches a width of 10 to 12 kilometers. The Verkhniye Mandrogi museum village is on the river .
The Swir represents the traditional southern border of the Karelia landscape.
