Selenga River

The Selenga or Selenge River (/sɛlɛŋˈɡɑː/[1] Mongolian: Сэлэнгэ мөрөн, romanized: Selenge mörön; Buryat: Сэлэнгэ гол / Сэлэнгэ мүрэн, romanized: Selenge gol / Selenge müren; Russian: Селенга́, IPA: [sʲɪlʲɪnˈɡa]) is a major river in Mongolia and Buryatia, Russia. Originating from its headwater tributaries, the Ider River and the Delger mörön, it flows for 992–1,024 kilometres (616–636 mi)[2][3][4] before drianing into Lake Baikal. The Selenga therefore makes up the most distant headwaters of the Yenisei-Angara River system.

Carrying 935 cubic metres per second (33,000 cu ft/s) of water into Lake Baikal, it makes up almost half of the riverine inflow into the lake, and forms a wide delta of 680 square kilometres (260 sq mi) when it reaches the lake.


The name Selenge comes from Mongolian seleh, which means "to swim". 'Selenga' is the russified version of the same.

An alternate source believes the name originated with the Evenki word sele ("iron") to which the nga suffix was added.[5]

The Selenge Province of Mongolia is named after the river.
