TheVolchya (Finnish:Saijanjoki (Saejoki, Sadejoki, Suenjoki, Sudenjoki);Russian:Волчья) is atributary of theVuoksi on theKarelian Isthmus (Leningrad Oblast,Russia) 0.25 to 12 kilometres (0.16 to 7.46 mi) west of theSaint Petersburg-Hiitola railroad (along the section between the stationsVaskelovo andLosevo) and flowing northwards from the Lembolovo Heights. It is 50 kilometres (31 mi) long, and has adrainage basin of 460 square kilometres (180 sq mi).[1] Its major tributaries are in turn the Smorodinka (right,Finnish:Tungelmanjoki;Russian:Смородинка), the Belaya (left,Finnish:Valkjoki;Russian:Белая), the Goryunets (left,Russian:Горюнец) and the Petrovka (right,Finnish:Petäjoki, Petojoki, Peto-oja;Russian:Петровка). The Volchya River's width is about 10 metres (33 ft) in the lower reaches, where it flows in a narrow valley, withmeanders andoxbow lakes. The Volchya is shallow and unavailable for navigation (except forcanoeing in some places)
The river is crossed by theSosnovo (Finnish:Rautu) –Pervomayskoye (Finnish:Kivennapa) road on Lembolovo Heights, Sosnovo – Borisovo (Finnish:Nurmijärvi) –Michurinskoye (Finnish:Valkjärvi) road at Razdolye (Finnish:Mäkrälä) and by the Losevo (Finnish:Kiviniemi) – Yagodnoye (Finnish:Vaalimo) road at the lower portion of the river.
Since 1928 there is a littlehydroelectric plant on the river not far fromPetäjärvi (now Petrovskoye), which was the largest private hydroelectric facility in pre-Winter WarFinland (owned by Leonard Sääksjärvi).[1]
The entire river was a boundary between theKingdom of Sweden andNovgorod Republic as defined in 1323 in theTreaty of Nöteborg. The higher reaches of the Saijanjoki (Volchya) to the south of the Tungelmanjoki (Smorodinka) and the Tungelmanjoki itself constituted part of theRussia-Finland border in 1811–1940. Now that stretch of the Volchya River dividesPriozersky andVyborgsky District fromVsevolozhsky District, while the Smorodinka marks another part of the boundary between Priozersky District and Vsevolozhsky District.
The river was renamed from the Saijanjoki to the Volchya (lit.Wolf River) in 1948, just like the vast majority of other Finnishhydronyms andtoponyms on the territories ceded by Finland to the Soviet Union as a result of theContinuation War.
