Numerous dams and reservoirs have been constructed in the Volga basin for flood control, improved navigation, irrigation, and hydroelectric power. There are many important hydroelectric stations, notably at Uglich, at Shcherbakov, and at Ivankovo, all along the upper Volga. At Ivankovo, NW of Moscow, a dam creates the vast Volga Reservoir or Moscow Sea, covering an area of c.125 sq mi (320 sq km); this is connected with the Moskva River by the Moscow Canal. Large hydroelectric stations have been built at Nizhny Novgorod, Samara, Kama, Volgograd, and Votkinsk.
