Airag Lake (Mongolia)

The lake was in the same basin as the Khyargas Lake in ancient times.

The depth of the lake generally varies with the inflow river flow. The lake flows into Khyargas Lake along a 5 km long, 200–300 m wide canal, which does not freeze in winter.

During the summer the lake warms up almost to the very bottom. Even in winter, the temperature remains fairly constant, 1 - 2.5 °C. Compared to other lakes, the water is not very clear.^[2]
