Khar-Us Nuur, Mongolia’s Great Lakes Depression – June 19th, 200947.9N 92.1E
The greenish waters of several lakes in Mongolia’s Great Lakes Depression stand out against the surrounding dry, tan landscape.
The lake on the bottom left is Khar-Us Nuur, or “Black Water Lake” despite its green appearance here. Its area value of 1,852 km² includes the island Agbash (or Ak-Bashi, White Head), with an area of 274 km², meaning the lake’s actual water surface area is only 1,578 km².
The lake’s primary inflow is from the Khovd Gol river, which creates a large river delta whose fanned shape is visible on the western shore.
It is the upper one in a system of the interconnected lakes: Khar-Us Nuur, Khar Nuur, Dörgön Nuur, Airag Nuur and Khyargas Nuur. Khar Nuur (above) and Dörgön Nuur (below) are located to the east of Khar-Us Nuur, while Khyargas Nuur (above) and Airag Nuur (below) are situated to the north.
