Main image

Böön Tsagaan Lake is a lake located in Bayankhongor Province in central Mongolia. It is one of several lakes in the region set within steppe and semi-arid landscapes.

The lake and its surroundings are typical of Mongolia’s inland lakes - open shoreline, steppe vegetation and seasonal wildlife usage. It is visited for landscape viewing, birdwatching and as part of wider overland routes through the province.

The lake is a natural feature of the Mongolian interior; local use has historically included seasonal grazing and water access for pastoral communities. Scientific and conservation work in some Mongolian lake systems has documented ecological variability, but specific published histories for this lake are limited.

Böön Tsagaan Lake lies in Bayankhongor Province in central Mongolia, set within the Mongolian steppe and distant from major urban centres.
