Dams of the Sestroretsky Razliv Reservoir

The dams of the Sestroretsk Razliv Reservoir are a hydraulic structure from the time of Peter I, blocking the Sestra and Chernaya rivers to raise the water level. After a flood washed away a wooden bridge, the surface of the 1833 earthen dam was adapted for traffic. The spillway dam is equipped with 18 two-tier metal gates, and the stability of their supports after the wear of cast iron buttresses in 1974 was ensured by concreting. A road bridge with an 8-meter-wide carriageway runs through the spillway structure, and the main Hausmann Dam, after restoration in 1985–1987, is capable of passing up to 35 cubic meters of water per second.
