Rybinsk Reservoir - a large reservoir on the river The Volga And its tributaries to Sheksna and Molode. It is located mainly in the Yaroslavl region, in the north-west, in part also in the Tver and Vologda regions. Formed at the end of the 30-X - the beginning of the 40-ies of the XX century, the water-retaining structures of the Rybinsk hydroelectric complex located in the northern part of Rybinsk, overlapping the channels of the two rivers: the Volga and Sheksna. The hydropower plant includes the building of the Rybinskaya HPP with the capacity of 346 MW (originally 330 MW) built on the old canal of Sheksna, earth dams and associated dams, a concrete weir dam and a two-channel sluice built on the channel of the Volga. The value of the reservoir: shipping, fishing, power generation of Rybinskaya HPP. About 17 thousand years ago on the site of the Rybinsk Reservoir was a glacial lake. Gradually it became shallow, and a vast Mologo-Sheksna lowland arose.

Main characteristics

The banks of the Rybinsk Reservoir are mostly low, along its coast stretches raw meadows, forests, swamps. Only in places along the valleys of flooded rivers can one find pines covered with pine trees. The height of the waves reaches two meters. With the advent of the Rybinsk Reservoir, the climate in the areas adjacent to it has changed. Summer has become more humid and cool, wheat and flax have ceased to ripen. For the winter the reservoir freezes. Ice keeps from the middle of November to the beginning of May. The average thickness of the ice reaches 60-70 centimeters. From the northwestern part of the shore of the Rybinsk Reservoir, large peat layers, overgrown with vegetation and even small trees, are often peeled off. They autonomously swim across the water area, creating minibiosystems. The ship's fairway is far from the coast. Navigation lasts an average of 190 days. Ports: Cherepovets - at the confluence in the reservoir of the Sheksna River, Vesyegonsk - at the confluence of the river Mologa. Through Sheksna the reservoir is connected with the Volga-Baltic water system.

The Rybinsk Sea is a giant laboratory of the Institute of Inland Water Biology of the Russian Academy of Sciences. In the north-western part of it is the Darwin Reserve, which specializes in research into the effect of the reservoir on the natural complexes of the southern taiga. Fish stocks of the Rybinsk Reservoir are: sterlet (family of sturgeon), tulka (family of herring), vendace and peled (squiggle family), smelt (family of smelt), pike (pike family), eel (catfish family), catfish (catfish family) Burbot (cod-family), goby-golovach (bovine family), sub-stalker (family of slingshot), loach, char, pinworm, common (family of loach).
