Additional Information The Volga River is one of the greatest rivers in Russia and the longest and most abundant in Europe. The length of the river is 3530 km. The Volga is the central waterway of the country and flows through its European part through the East European (Russian) Plain. It is the largest river in the world, flowing into an internal reservoir. The area of ​​the delta formed by the Volga, is 19,000 square km. The river takes its origin from a small source of groundwater, located near the village Volgoverkhovye and located at an altitude of 229 meters above sea level. A small stream, receiving about 150,000 tributaries, among which there are about 200 small and large rivers, is gaining power and strength and turns into a mighty river, which flows into the Caspian Sea. The fall of the river throughout its length does not exceed 250 meters, and the basin area is 1,360,000 square km. The main supply of the Volga is thawed spring water. Summer rains and groundwater, which feed the river during the winter period, play a slightly smaller role. In connection with these features in the annual level of the river there are three periods: long and high spring floods, stable summer low water and winter low water. There are numerous islands on the river, many of which have inland lakes connected with the main channel during flood. In places, the banks of the Volga are composed of rocks of marine origin, formed in the Jurassic and Cretaceous periods of the Mesozoic era. Therefore, in the water and on the shores, the remains of marine invertebrates are often found, and sometimes even the bones of Mesozoic lizards.Since the Upper Volga flows predominantly through large forests, at the bottom, especially in places with a less rapid current, driftwood accumulate. The bottom of the Volga in different places can be sandy or muddy, often there are silt and sandy areas.
