The Peswo Lake ( Russian Песьво Озеро / Peswo osero , scientific transliteration Ozero Pes'vo ) is located in the Udomlja district of the central Russian Tver Oblast .
With a maximum north-south extension of 4.3 km and a maximum east-west extension of 2.9 km, it occupies a total area of 6.3 km². The water depth is 2.7 m on average and 5.2 m at the deepest point. The lake is fed by the Syutscha River in the southeast and by eleven streams that flow into it. The water of the Peswo Lake flows into the neighboring Udomlja Lake , on the one hand through a natural arm of water in the northeast near Bereshok and on the other hand through a formerly natural river course in the east; this was expanded into a canal for the benefit of rafting in the 1920s and widened again in the course of the construction of the nuclear power station on Lake Udomlja (from 1974). Of the original five islands consist of a post-construction weir at Udomlya Lake today only four.
history
As early as the Middle Ages , Lake Pesvo played an important role as a traffic route, as it served as part of the connection between Veliky Novgorod and the Volga region . This path once led over the Ilmen Lake , the rivers Msta , Uwer , Sescha and the Udomlja Lake, first to Lake Peswo and after overcoming the Svetliza Heights via the Svetliza River and Lake Kubytscha to the Mologa , a tributary of the Volga. From 1869 the town of Udomlja developed on the south bank of Lake Peswo . From 1974, the Kalinin nuclear power plant was built in the area of the northeast bank , which had a lasting effect on the lake's ecosystem .
Flora and fauna
The shores of the lake are largely unforested, as the forests near the water were cleared in pre-Slavic times. The warming of the water by the adjacent nuclear power plant has led to the extinction of the whitefish and a steady decline in the Moderlieschen and pike populations in the lake. Other fish species that occur in Lake Peswo are white bream , pikeperch , grass carp and silver carp .
