Tso Moriri or Lake Moriri or "Mountain Lake", is a lake in the Ladakhi part of the Changthang Plateau (literally: northern plains) in Jammu and Kashmir in northern India. The lake and surrounding area are protected as the Tso Moriri Wetland Conservation Reserve.The lake is fed by springs and snow-melt from neighboring mountains.The lake is at an altitude of 4,522 m (14,836 feet). It is the largest of the high altitude lakes entirely within India and entirely within Ladakh in this Trans-Himalayan biogeographic region.Most water enters the lake in two major stream systems, one entering the lake from the north, the other from the southwest. Accessibility to the lake is largely limited to summer season, though Karzok on the northwest shore and the military facilities on the eastern shores have year-round habitation.
