Malaya Sestra River

Malaya Sestra is a river 4.8 kilometers long, flowing in Sestroretsk and flowing into the Gulf of Finland. In its lower reaches, it forms a delta of two branches that create an island, on which the "Belye Nochi" and "Dyuny" sanatoriums, as well as the "Dyuna" golf club, have been located since 1988. Many pedestrian bridges have been built to connect the banks, but there are only two automobile crossings — at the dam in Sestroretsk and a cable-stayed bridge near the "Belye Nochi" sanatorium. The ecological state of the river remains complex due to garbage on the banks and the contamination of the Sestroretsky Razliv reservoir with toxic blue-green algae, although in 2013 work on the improvement of the mouth and the lining of the channel was completed.
