Khar Lake (Mongolian: Хар нуур, lit. "black lake"), is located in the Khovd aimag (province) in western Mongolia's Great Lakes Depression.


It is also known as Ha-la Hu, Hara Nuur, Har Nuur, Khara Nur, Khar Nuur, and Ozero Kara-Nor[3]

It should be distinguished from the similarly named Khar Lake (Zavkhan), another lake further east in Mongolia.


It is part of a group of lakes that were once part of a larger prehistoric lake that disappeared 5,000 years ago as the region became drier.

Some sources are using different Khar Lake statistics values:[4]

  • Water level: 1,134.08 m
  • Surface area: 565.2 km²
  • Average depth: 4.14 m
  • Volume: 2.34 km³.
