Tsomoriri or Lake Moriri (official name: Tsomoriri Wetland Conservation Reserve), in the Changthang (literal meaning, northern plains) area, is a High Altitude Lake (HAL) with an altitude of 4,595 m (15,075 ft) in Ladakh, India and is the largest of the High Altitude Lakes in the Trans-Himalayan biogeographic region, entirely within India. It is hemmed between Ladakh in the North and Tibetin the east and Zanskar in the west; the Changthang plateau is the geographical setting with snow peaks that provides the source of water for the Lake. Accessibility to the lake is limited to summer season only. Tsokar means salty lake in local language and salt was extracted from this lake in earlier times, till the end of 1959, for consumption by the local people. It is oligotrophic in nature and its waters are alkaline. The lake formerly had an outlet to the south, but it has contracted considerably and has become land locked; as a result; the water is now brackish to saline. The lake is fed by springs and snow-melt in two major stream systems, one entering the lake from the north, the other from the southwest. Both stream systems create extensive marshes where they enter the lake.
