Lake Manasarovar

Lake Manasarovar lies at 4,590 meters (15,060 ft) above mean sea level, a relatively high elevation for a large freshwater lake on the mostly saline lake-studded Tibetan Plateau. Despite claims to the contrary, there are hundreds of higher freshwater lakes in the world, including a larger and higher freshwater lake at 4,941 meters (16,211 ft) above sea level and 495 km² in size, Angpa Tso(also known as Chibzhang Co, Migriggyangzham Co, East Chihpuchang Hu), further east on the Tibetan Plateau at 33°24′N 90°17′E. The largest freshwater lake of its size (290 km²) over 5000 meters elevation is Pumoyong Tso (also known as Puma Yumco, Po-mo Hu, Pumuoyong Tso), also on the Tibetan Plateau, at 28°34′N 90°24′E at 5,018 metres (16,463 ft) elevation.

Lake Manasarovar is relatively round in shape with the circumference of 88 kilometers (55 mi). Its depth reaches a maximum depth of 90 m (300 ft)  and its surface area is 320 square kilometers (120 sq mi). It is connected to nearby Lake Rakshastal by the natural Ganga Chhu channel. Lake Manasarovar is near the source of the Sutlej, which is the easternmost large tributary of the Sindhu. Nearby are the sources of the Brahmaputra River, the Indus River, and the Ghaghara, an important tributary of the Ganges.

Lake Manas Sarovar overflows in to lake Rakshastal which is a salt-water endorheic lake. These lakes used to be part of the Sutlej basin and were separated due to tectonic activity.
