Rybinsk Sea is one of the biggest manmade reservoirs in the world. It stretches for 140 km, reaching a width of up to 60 km. From here a route to the Baltic Sea through the Volga-Baltic system can be laid. The route also runs to the White Sea via the Belomor-Baltic Canal. We also can run down the Volga to the Caspian, Azov and Black Seas through a Rybinsk lock.
The Rybinskoye Sea is the first fresh sea created during the Soviet period. Building began before the great Patriotic War with Fascist Germany. It was filled only in 1947, when the Volga, Mologa and Sheksna Rivers as well as many small rivers carried into it hundreds of thousands of cubic meters of vernal (spring) floods.
Twenty-five billion cubic meters of water put into motion turbines of the hydro plant as well as making it possible to travel to five seas.
The Rybinsk lock is very big and interesting. It has two sections and vessels running in opposite directions can be transferred simultaneously.
After the huge sea we find ourselves on a narrow river.
