The Volga is the longest river in Europe. Situated in Russia, it flows through Central Russia to Southern Russia and into the Caspian Sea. The Volga has a length of 3,531 km (2,194 mi), and a catchment area of 1,360,000 km2 (530,000 sq mi). It is also Europe's largest river in terms of average discharge at delta – between 8,000 m3/s (280,000 cu ft/s) and 8,500 m3/s (300,000 cu ft/s) – and of drainage basin. It is widely regarded as the national river of Russia. The hypothetical old Russian state, the Rus' Khaganate, arose along the Volga c. 830 AD. Historically, the river served as an important meeting place of various Eurasian civilizations.
The Sea of Azov is an inland shelf sea in Eastern Europe connected to the Black Sea by the narrow Strait of Kerch, and is sometimes regarded as a northern extension of the Black Sea. The sea is bounded by Russia on the east, and by Ukraine on the northwest and southwest, currently under Russian occupation. It is an important access route for Central Asia, from the Caspian Sea via the Volga–Don Canal.
The Don is the fifth-longest river in Europe. Flowing from Central Russia to the Sea of Azov in Southern Russia, it is one of Russia's largest rivers and played an important role for traders from the Byzantine Empire.
Lenin Volga–Don Shipping Canal is a ship canal in Russia. It connects the Volga and the Don at their closest points. Opened in 1952, its length is 101 km (63 mi), 45 km (28 mi) of which is through rivers and reservoirs.
The Manych is a river in the Black Sea–Caspian Steppe of Southern Russia. It flows through the western and central part of the Kuma–Manych Depression. In ancient times, it was known as the Lik.
Tsimlyansk Reservoir or Tsimlyanskoye Reservoir is an artificial lake on the Don River in the territories of Rostov and Volgograd Oblasts at 47°50′N42°50′E. Completed in 1952, the reservoir is one of the largest in Russia, providing power and irrigation to the Rostov and Volgograd regions. Crops grown around the lake include wheat, rice, cotton, maize, alfalfa, fruit, grapes, and vegetables.
The Kuma is a river in the North Caucasus region of southern Russia. It flows northeast into the Caspian Sea. It is 802 kilometres (498 mi) long and has a drainage basin of 33,500 square kilometres (12,900 sq mi). Its source is in the Greater Caucasus, in the republic Karachay-Cherkessia, west of Kislovodsk. It flows in a northeastern direction, through Stavropol Krai and further east through the Caspian Depression as the natural border between the Kalmykia and Dagestan republics of Russia. That part of the Kuma's valley forms the eastern part of the Kuma–Manych Depression, separating the East European Plain from the Caucasus region. The Kuma flows into the Kizlyar Gulf of the Caspian Sea near the border between Dagestan and Kalmykia.
The Volga–Baltic Waterway (Волгобалт), formerly known as the Mariinsk Canal System, is a series of canals and rivers in Russia which link the Volga with the Baltic Sea via the Neva. Like the Volga–Don Canal, it connects the biggest lake on Earth, the Caspian Sea, to the World Ocean. Its overall length between Cherepovets and Lake Onega is 368 kilometres (229 mi).
The Volga Delta is the largest river delta in Europe and occurs where Europe's largest river system, the Volga River drains into the Caspian Sea in Russia's Astrakhan Oblast, north-east of the republic of Kalmykia. The delta is located in the Caspian Depression—the far eastern part of the delta lies in Kazakhstan. The delta drains into the Caspian approximately 60 km (37 mi) downstream from the city of Astrakhan.
The Kuma–Manych Canal is an irrigation canal in Russia's Stavropol Krai. The canal, completed in 1965, runs across the Kuma–Manych Depression, connecting the Kuma River, which flows into the Caspian Sea, with the East Manych River, which also flows toward the Caspian, but dries out long before reaching it. The East Manych River should not be confused with the West Manych, a tributary of the Don which flows into the Sea of Azov and connects to the Black Sea.
Lake Manych-Gudilo is a large saltwater reservoir lake in Kalmykia, Russia. Part of the lake lies also in Rostov Oblast and Stavropol Krai. It has an area of about 344 km² and average depth of only about 0.6 m.
The Northern river reversal or Siberian river reversal was an ambitious project to divert the flow of the Northern rivers in the Soviet Union, which "uselessly" drain into the Arctic Ocean, southwards towards the populated agricultural areas of Central Asia, which lack water.
The Eurasia Canal is a proposed 700-kilometre-long (430 mi) canal connecting the Caspian Sea to the Black Sea along the Kuma-Manych Depression. Currently, a chain of lakes and reservoirs and the shallow irrigation Kuma–Manych Canal are found along this route. If completed the canal would also link several landlocked countries in Asia with the open seas through the Bosphorus.
The Caspian Sea is the world's largest inland body of water, often described as the world's largest lake and sometimes referred to as a full-fledged sea. An endorheic basin, it lies between Europe and Asia: east of the Caucasus, west of the broad steppe of Central Asia, south of the fertile plains of Southern Russia in Eastern Europe, and north of the mountainous Iranian Plateau. It covers a surface area of 371,000 km2 (143,000 sq mi), an area approximately equal to that of Japan, with a volume of 78,200 km3 (19,000 cu mi). It has a salinity of approximately 1.2%, about a third of the salinity of average seawater. It is bounded by Kazakhstan to the northeast, Russia to the northwest, Azerbaijan to the southwest, Iran to the south, and Turkmenistan to the southeast.
The Chogray Reservoir is an artificial reservoir on the East Manych River on the border of Stavropol Krai and Kalmykia in southern Russia.
East Manych is a river in the eastern and central part of the Kuma–Manych Depression in southern Russia.
Rostov Nature Reserve is a Russian 'zapovednik' that protects a variety of sensitive southern European steppe wetlands, the largest herd of wild horses in Europe, and also wetland habitat for birds. The protected areas are divided into five sections that cover the waters of Lake Manych-Gudilo, islands in that lake, surrounding steppe and shore lands. The reserve is situated in the Orlovsky District, of Rostov Oblast, about 100 km northeast of Rostov-on-Don. It is part of a Ramsar Wetland site of international importance.
The Unified Deep Water System of European Russia or UDWS is a system of inland waterways in Russia linking the White Sea, the Baltic Sea, the Volga River, Moscow, the Caspian Sea and—via the Sea of Azov—the Black Sea. In 2010, UDWS carried 70 million tons of cargo and 12 million passengers, making up two-thirds of overall inland waterway traffic volume in Russia. There are 60 common-use ports and quays in the UDWS, including three international ports, so Moscow is sometimes called "the port of the five seas".
The Vodny Island is the uninhabited island situated in the northern part of the Manych-Gudilo Lake, Orlovsky District, Rostov Oblast, Russia.
Yergeni is a hilly area in Russia. It is located in the southern corner of the East European Plain, mostly in Kalmykia, with parts in Volgograd Oblast and Rostov Oblast. The highest point of Kalmykia, 222 metres (728 ft) high Shared, is located in the Yergeni hills.
