It was reported in 2021 that the lake receives "good environmental protection".

It has an area of 260 km² (100 square miles) and an elevation of 4,459 meters above sea level."Plateau lakes in Tibet with an altitude of more than 4,400 meters Dazecuo: good ecology and beautiful scenery". China News Agency. July 29, 2021. Retrieved May 16, 2022. In 2021 the lake was 21.1 kilometers in length and 16.9 kilometers wide.

In glacial times, the region was considerably wetter, and lakes were correspondingly much larger. Changes in climate have resulted in greater aridity on the Tibetan Plateau. The numerous concentric rings that circle the lake are fossil shorelines, and attest to the historical presence of a larger, deeper lake.
