Tibetan for “high grassland lake”, also referred to as Pangong Lake, is an endorheic lake in the Himalayas situated at a height of about 4,350 m (14,270 ft). It is 134 km (83 mi) long and extends from India to the Tibetan Autonomous RegionChina. Approximately 60% of the length of the lake lies within the Tibetan Autonomous Region. The lake is 5 km (3.1 mi) wide at its broadest point. All together it covers 604 km2. During winter the lake freezes completely, despite being saline water. It is not a part of the Indus river basin area and geographically a separate landlocked river basin.

Flora, fauna and geography

The eastern part of the lake is fresh, with the content of total dissolved solids at 0.68 g/L, while the western part of the lake is saline, with the salinity at 11.02 g/L. The brackish water of the lake has very low micro-vegetation. Guides report that there are no fish or other aquatic life on the Indian side of the lake, except for some small crustaceans. On the other hand, visitors see numerous ducks and gulls over and on the lake surface. There are some species of scrub and perennial herbs that grow in the marshes around the lake.

The lake acts as an important breeding ground for a variety of birds including a number of migratory birds.
