On May 20, all regions along the Volga River in Russia celebrate the great river's day – Volga Day. The Volga is one of the largest rivers not only in Russia but also in Europe. Its length is 3,530 kilometers. The basin area, covering 8% of Russia's territory, is 1,360,000 square kilometers. Nearly half of all the country's agricultural lands and industrial enterprises are located in the Volga region. Over 60 million people live in the river basin area. Annually, about 250 cubic kilometers of water flow through the Volga. Volga Day was first celebrated in 2008 in Nizhny Novgorod during the 10th International Scientific and Industrial Forum "Great Rivers – 2008." Subsequently, other regions of Russia joined the celebration, including the Volgograd, Astrakhan, Yaroslavl, Samara regions, and the Republic of Tatarstan. The organizers aim to draw the attention of authorities and the public to the issue of preserving the river, which is not only the national pride of the country but also a valuable strategic natural resource. The river's role in water transport is equally important. Through the canal system, it is possible to reach the Caspian, Black, Azov, Baltic, and White Seas. However, intense human economic activity and the development of scientific and technological progress lead to the pollution and shallowing of the Volga. The use of chemical fertilizers to increase agricultural yields, the large number of industrial enterprises on the riverbanks, the cascade of hydroelectric power stations, and other "traces of civilization" are to blame. The Russian Ministry of Natural Resources, as part of the national project "Ecology," is implementing the federal project "Volga Health" and the federal project "Conservation of Unique Water Bodies," which aim to improve the river's ecological state. Success in this endeavor can only be achieved through the joint efforts of the state, Volga regions, and commercial companies whose enterprises are located on the riverbanks.
