The Selenga River, the largest tributary of Baikal, is starting in Mongolia. Selengi's origin is the Idair-Gol River merger and Delgair-Muren.

There's a few hypotheses about Selenga's far past. According to one, in a very ancient time, before the formation of the Baikal Valley, Selenga and Angara were one river. Another hypothesis suggests Selenga was once a tributary of Lena.

There is no single view on the origin of Selenga. There is a theory that the word " selenga " originated from the Evenki Selé " , a " Jeloso " , another version, from the Burundian " Sel " , " Strait " , " Gosero " . Against the second version, the name " Selenga " was used at a time when the Buryats as a nation had not yet developed and against the first thing that there was no connection to the Seleng iron.

The Selengi from the East, a merging site with the Idair Gul River, before entering Baikal about 870 km, of which 360 km are in Russia. Selenga watershed area is about half a million square kilometres. Selengu feeds thousands of tributaries, the largest of which are the Jeda, Temnik, Chika, Hilok, Ouda. Fifty-five per cent of the Selengi watershed is in Mongolia.

On average, in the year, Selenga brings about 30 km3 of water to Baikal, which is about half of the total flow to the lake. During the year, the flow in Selenga is unevenly distributed. The river is the largest in June and July, the least in January, February and March. Together with Selenga ' s water, half the total amount of lake-borne pollution is delivered to Baikal. Selenga has floods, summers after heavy rains, and turbulent spring floods when the river level rises at a speed of up to 20 cm/h.

Selenga is carrying a huge amount of solid weight in Baikal, sand, etc., on average 3.6 million tons per year, and during floods the amount of sand can reach 7 million tons per month.

When entering Baikal Selenga, there is a huge delta, which is a multi-kilometre thickness of the river ' s slope of the Baikal reef. Selenga Delta rainfall is estimated at 5,000 to 5,500 metres. The outer delta looks like a giant, swamp plague plain divided into the islands by many pros and olds. The submarine part of the Selenga Delta reaches the West Bank Lake Baikal
