Sestroretsky Razliv

Sestroretsky Razliv is a reservoir with an area of 10.6 square kilometers in Sestroretsk, created in Petrine times by damming the Sestra and Chernaya rivers. By the end of the 19th century, it had lost its original significance as an energy hydraulic structure after the local factory switched to steam engines. In winter, the water area of 12 square kilometers turns into a public ice rink, however, diving in places with liquid viscous silt at the bottom is deadly dangerous, as it sucks in the feet. This object, number 25, was included in the list of cultural and natural heritage of Leningrad under the auspices of UNESCO in 1990.
