TheIzhora (Russian:Ижора,Finnish:Inkereenjoki), also known as theInger, is a lefttributary of theNeva on its run throughIngria in northwesternRussia fromLake Ladoga to theGulf of Finland. The Izhora flows throughGatchinsky andTosnensky Districts ofLeningrad Oblast as well as throughPushkinsky andKolpinsky Districts of the federal city ofSaint Petersburg.[1] The settlement ofUst-Izhora (lit. "mouth of Izhora") is situated at the confluence of Izhora and Neva, halfway between Saint Petersburg andShlisselburg. The towns ofKommunar andKolpino are located on the Izhora as well. The river is noted as the farthestSwedish forces ever reached between theViking Age and theTime of Troubles.
The length of the Izhora is 76 kilometres (47 mi), and the area of itsdrainage basin is 1,000 square kilometres (390 sq mi). The river draws its water mainly from natural groundwater springs, snow melt, and rain water. The river has a sustainable underground water supply in both summer and winter, never drying up or freezing through.
The source of the Izhora is located on theIzhora Plateau at the village ofSkvoritsy [ru], northwest of the town ofGatchina. The Izhora flows to the east, passes at the northern outskirts of Gatchina, and east of Kommunar enters Tosnensky District. There, for a short stretch it makes the border between Saint Petersburg (north) and Leningrad Oblast (south), returns to the oblast and gradually turns north. In Kolpino, the Izhora enters the federal city of Saint Petersburg. There, it flow north and joins the Neva in the settlement ofUst-Izhora.
The drainage basin of the Izhora includes the northern parts of Gatchinsky and Tosnensky Districts, as well as some areas within Saint Petersburg.
