Khar Lake (Mongolian: Хар нуур, ᠬᠠᠷ᠎ᠠᠨᠠᠭᠤᠷ; lit.

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] Khar Lake has a single inflow - Chono Kharaikh Gol river, which creates a river delta.

Khar Lake has a connection to Dörgön Nuur south of it.
