Volga

The Volga region of Russia stretches along the greatest river of European Russia, Volga River. It has highly developed hydroelectric power installations, including major dams at Volgograd, Kazan, Samara (formerly Kuybyshev), and Balakovo. Farm machinery, ships, chemicals, and textiles are manufactured, and extensive oil and gas fields are worked. Agricultural products include wheat, vegetables, cotton, hemp, oilseeds, and fruit. Livestock raising and fishing are also important.
