Main image

Orog Lake is a lake in Bayankhongor Province in central Mongolia. It is one of many inland lakes in Mongolia’s interior and forms part of the region’s freshwater and wetland systems.

The lake lies within a semi-arid steppe and basin landscape where lakes can be important for local wildlife, grazing and seasonal use. Many Mongolian lakes of this kind experience seasonality in water level and ecological characteristics.

As a geographic feature in Bayankhongor Province, it is used primarily in local land- and water-use practices rather than as a major tourist attraction. The lake is reached via regional roads and tracks from provincial centers.

Geographically the lake sits in central Mongolia’s basin landscapes, well inland from major cities and within the administrative area of Bayankhongor Province.
