Khar-Us Lake (Mongolian: Хар-Ус нуур, lit. "black water lake") is a lake in western Mongolia in the Great Lakes Depression. It is the upper one in a system of the interconnected lakes: Khar-Us, Khar, Dörgön, Airag and Khyargas.
Its area value (1,852 km²) includes the island Agbash (or Ak-Bashi ,white head) area (274 km²), so the water surface area is 1,578 km² only[1].
Some sources are using different Khar-Us Lake Lake statistics values[2]:

Primary inflow is the Khovd River, which creates a large river delta.
