Selenga

The Selenga or Selenge (/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 and the Delger mörön, it flows for 992–1,024 kilometres (616–636 mi)[2][3][4] before draining into Lake Baikal. The Selenga therefore makes up the most distant headwaters of the Yenisey-Angara river system.
