TSO MORIRI or Lake Moriri (official name: Tso Moriri 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 Tibet in 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. The lake formerly had an outlet to the south,
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. Administratively Tsomoriri has been declared as a wetland reserve. A Number of species of birds included Bare-headed Goose, the Great-crested Grebe, the Brahmin Duck and the Brown-headed Gull. Himalayan Hares and the Tibetan Wild Ass or the Kiang are abundantly found here.
