Uvs Lake is the largest saline lake (3,350 sq. km) in Mongolia and forms unique wetlands in the Great Lakes Depression. Its salinity varies between 3 and 35 g/l. With its reed beds and freshwater river deltas it provides significant nesting and resting areas for numerous migratory species. The shallow lake lies at an altitude of 759 m.


Uvs Lake is part of the Uvs-Nuur-Basin compassing different ecosystems. This area ranges from the permanent snowfields in the Turgen mountains over the lakes and wetlands areas up to the desert of Altan Els. The whole area measures 10,688 sq. km. The range lies at altitudes between 2,500 and 4,000 m.


Because of this geographical situation , the Uvs Lake is subject to extreme climate fluctuations. Temperatures of – 40 °C are normal in winter, also – 58 °C are measured. In summer, the basin warms and the temperatures arrive + 40 °C. Uvs Lake underlies, compared to locations of the earth at the same altitude, both the coldest and the warmest as well as the driest conditions.
