Despite the presence of the Gobi Desert, Mongolia is rich in rivers and lakes. The total water resources of Mongolia has about 34 billion cubic meters. meters. Most of that – fresh water. 51% of the volume of water discharged into the basin of the Northern -Ledovitogo Ocean, 12% in the Pacific, and the remaining 37% in the Central Asian pool (with no flow in the ocean) .In the country has nearly 4,000 rivers with a total length of more than 40.390 miles (65.000 km.).
The rivers are born in the mountains of Mongolia. Most of them – the upper reaches of the great rivers of Siberia and the Far East, which flows into the side of the Arctic and Pacific oceans. The largest rivers of the country – Selenga (within the boundaries of Mongolia – 600 km), Kerulen (1100 km), Onon (300 km), Khalkhin goal Kobdo and others. The deepest – Selenga. It starts with one of the ridges Hangu takes a few major tributaries – Orkhon, Hanuy-goal Chulutyn-goal Delger-Muren and others. The speed of its flow – from 1.5 to 3 meters per second. In any weather its rapid cold water flowing into the clay-sand beaches, and therefore always murky, are dark gray in color. Selenga frozen for six months, the average thickness of ice – from 1 to 1.5 m. It has two floods of the year: spring (snow) and summer (the rain). The average depth at the lowest level of water – at least 2 m. After leaving the limits of Mongolia, Selenge flows through the territory of Buryatia and empties into the lake.
Rivers in the western and southwestern parts of the country, flowing down from the mountains fall into the intermountain basin, exit to the ocean and have, as a rule, end its way in one of the lakes.
In Mongolia, there are over a thousand permanent lakes and a much greater amount of time, resulting in the rainy season, and endangered in times of drought. In rannechetvertichny during a significant part of the territory of Mongolia was an inland sea, later divided into several large reservoirs. Current lakes – what was left of them. The largest of them are in the Great Lakes Depression in the north-west of the country – Uvs Nuur, Har Us Nuur, Hirgis-nur, the depth does not exceed a few meters. In the east, there is the lake Buir-Nur and Huh-Nur. The giant tectonic basin in northern Hangai is Lake Hovsgol (depth to 238 m), similar to the composition of Baikal water relict flora and fauna.

The average consumption of water 40 km from the mouth of about 100 m3 / s. Flows into Lake Hovsgol small rivers are shallow and of no interest to the water tourists. Egiyn Gol River flows from the lake. Khubsugul powerful high-water flow, but after some time is divided into a plurality of channels, heavily overgrown with willows. In 1997, the first few kilometers of the river Egiyn Gol, flowing from the lake, organized competitions kayaking among the participants of the international mileage Camel-Trophy “Mongolia-97.” Slow and shallow depths within the middle reaches Egiyn Gol, sometimes knee-deep, tiring rafters in their monotony. Kayaking can go all over the river, but on motorboats in a number of places to swim in the shallow water is simply impossible. In April 2003, for hydraulic Lake. Hovsgol – p. Egiyn Gol – p. Selenge – Lake. Baykal made the first passage to the tourist hovercraft “Khivus-6.”
In April – May, the narrowing of the river valley. Egiyn Gol formed extensive ice, reaching heights of up to 2 m. At this time, the river cuts through the deep and narrow canyons of ice, sometimes ending ice caps. The banks of the river, especially in the upper reaches, wooded, but even here a lot on the river terraces of cattle and Mongolian yurts. Rafting difficult heavy floods, create additional bayous leading to nowhere and disappear gradually.
Throughout a great river fishing – catch trout, grayling or lenok is not a problem.
On the territory of the country revealed more than 400 hot and cold mineral sources of carbon dioxide, which are suitable for bathing and drinking. Some of them operate resorts aimak values.
