Main image

Ivankovo Reservoir is a large reservoir on the Volga River, extending into Tver Oblast and adjoining regions. It is commonly known as the Moscow Sea because of its size and role in Moscow’s water system.

The reservoir lies north of Moscow and straddles administrative borders, with shoreline in Tver Oblast and neighbouring territories. It is linked to the Volga waterways and to canals that connect the river system to the Moscow area.

  • Also called Moscow Sea: Often referred to as the "Moscow Sea," it is a large reservoir on the Volga River that forms part of the water system supplying Moscow.
  • Function: Created by damming the Volga, it serves navigation, water supply and hydroelectric purposes for the surrounding region.
