The lake is at an altitude of 4,522 m (14,836 ft). It is the largest of the high altitude lakes entirely within India and entirely within Ladakh in this Trans-Himalayan biogeographic region. It is about 16 miles (26 km) north to south in length and two to three miles (3 to 5 km) wide. The lake has no outlet at present and the water is brackish though not very perceptible to taste.

The lake is fed by springs and snow-melt from the adjacent mountains. Most water enters the lake in two major stream systems, one entering the lake from the north, the other from the southwest. Both stream systems include extensive marshes where they enter the lake. It formerly had an outlet to the south, but this has become blocked and the lake has become an endorheic lake. The lake is oligotrophic in nature, and its waters are alkaline.

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.[4]


Topography


As per a classification of the Himalayan Lakes done on the basis of their origin, there are four groups and Tso Moriri falls under the third group of "remnant lakes". The classification as reported states:[5]

(i) Glacial lakes which are formed in and around glaciers; (ii) Structural lakes, formed by folds or faults due to movements in earth’s crust (e.g. Nainital lake in Uttarakhand), (iii) Remnant lakes which were originally structural but represent the remnants of vast lakes (e.g., Tso Moriri, Tso Kar, Pangong Tso in Ladakh, and Dal Lake in Kashmir), (iv) Natural dammed lakes i.e., temporary water bodies formed along the river courses due to deposition of rocks or debris e.g. Gohna Tal in Garhwal, Uttarakhand.

The Changthang Plateau in the eastern Ladakh represents a landscape of low productive ecosystems which protects unique floral and faunal species. The area is an extension of the western Tibetan plateau that lies above 4,500 m (14,800 ft) msl and supports diverse but low populations of several globally threatened mammals.[5] The lake's basin could also be categorised as a basin since it is a closed drainage basin that retains water and allows no outflow to other bodies of water such as rivers or oceans.

The lake is 20 to 50 kilometers southeast of the elevated valley of the core Rupshu Valley and falls within the greater Rupshu Plateau and valley area. The lake is ringed by mountains rising over 6,000 m (20,000 ft), including Mentok Kangri and Lungser Kangri. "Changpa", the nomadic migratory shepherds (pastoral community) of yak, sheep, goat, and horses of Tibetan origin and who are engaged in trade and work on caravans in Ladakh region, are the main inhabitants of the area.[6][7] Changpa (Champa) herders use the land of this valley as grazing ground and for cultivation.[5]

The Working Report (2006) of the Planning Commission of the Government of India also reports:[5]

Despite a poor vegetation cover, relatively low standing biomass and high anthropogenic pressure, this area sustains a considerably high livestock population. Steady increase in the livestock population in the area is mainly attributed to influx of nomadic herders from Tibet during recent decades and promotion of Pashmina goat production by the Animal Husbandry Department (AHD) for fine quality under wool (Pashmina). The herders and AHD officials, in recent years have begun to raise concern over degradation of pastures, resultant shortage of forage, and mass mortality of livestock during severe winters.

The Korzok Monastery, on the western bank of the lake is 400 years old and attracts tourists and Buddhist pilgrims. Tourism during May – September attracts large number of foreign and local tourists even though tented accommodation is the facility available, apart from a small PWD guest house close to the Lake.[4] Northeast of Tso Moriri is a small lake which is known locally as Lake of Joy.


Access


The lake is located to the southeast of Leh in eastern Ladakh, ladakh, at a road distance of 240 kilometres (150 mi). The road is in a good condition for the most part. One can also reach Tsomoriri directly from the Pangong Tso via the remote Changtang region. This is considered to be one of the most beautiful drives in the entire Ladakh region. Foreigners are not allowed to go beyond the Man - Merak villages on Pangong Tso as permits are not issued for them. The distance between Pangong Tso and Tso Moriri is 235 km and there are no petrol pumps in the area. Carrying enough fuel is therefore necessary. Leh is also connected by air with many destinations in India.


Hydrology and water quality

The lake, with water spread area of 120 km2 (46 sq mi) is enclosed by peaks exceeding 6,000 meters on both the east and west sides. On the south, a nearly flat valley connects with but does not drain into or out of the Pare Chu river which is part of Sutlej river basin. Lingdi Nadi, major tributary of Tso Moriri, drains western catchment area of the lake and joins the lake on its south side.[8] This valley contains the Nuro Sumdo wetlands (with a catchment area of 20 km2 or 7.7 sq mi), a boggy area that mostly drains into the Pare Chu. Several small mountain streams feed the lake, including one through pasture land at Peldo Le. The lake is fed by springs and snow melt and has a maximum depth of 40 m (130 ft). Aridity and cold desert conditions prevail in the lake region; with summer temperature varying from 0° to 30 °C (32° to 86 °F) and winter temperature recording 10° and 40 °C (14° to -40 °F). Geologically the lake is in Ordovician rock.[9][10]

Vegetation


While the deeper parts of the lake have no vegetation, the shallow areas are reported to have Potamogeton sps. Marshes have several species of sedges and reeds, particularly Carex, Caragana and Astragalus sps., which are all representative of the surrounding arid steppe vegetation. Details of the Vegetation recorded in the area comprises the following:[10]


Ramsar site


Largely based on the ecological diversity of the Lake (explained in the previous section) and its surroundings, the Tsomiriri was notified in November 2002 under the List of Ramsar Wetland sites under the Ramsar Convention. The justification could be summarized as:[10]

There are a number of threats to the Lake, such as:[4][10]


Conservation efforts


The need for evolving a strategy and an action plan to preserve the extreme fragility of the lake ecosystem has been recognized with the needed emphasis at the National and International level to develop the lake conservation activity with participation of all stakeholders.[12] The actions initiated in this direction are:

Tso Moriri is an administratively declared Wetland Reserve. Legally, shooting wildlife is prohibited. The State Department of Wildlife has set up a check post near Mahe Bridge at the entrance towards the lake.[9][10] WWF-India Project has established a field office at Korzok on the northwest shore of Tso Moriri for ‘Conservation of High Altitude Wetlands in Ladakh Region’ to carry out surveys, interact with tourists, tour guides, act as information centre and conduct education awareness programmes for locals, tourists etc.

Wildlife Institute of India has also set up a field station at Leh to carry out scientific research in the region. Nature clubs have been set up and Information booklet on the lake published. Efforts of WWF – India has also resulted in the local community declaring Tso Moriri as a ‘Sacred Gift for a Living Planet’ during the Annual Conference held in Nepal in November 2000.[10]

Some of the other achievements so far reported on the Lake's conservation are:[12]

The Indian Army has committed to support and set up a Nature Interpretation Centre at 'Hall of Fame', Leh.


World Wildlife Fund’s (WWF) role


World Wildlife Fund for Nature India (WWF-India) is spearheading the efforts at conservation of the Tso Moriri lake in particular, and the Ladakh region in general. WWF's activities as a NGO have spanned more than 30 years. The main objective set by WWF is[13] the main activities planned for the Tso Moriri and other wetlands in Ladakh regions are:[12]

The Promotion of Nature Conservation and Environmental Protection as the Basis for Sustainable and Equitable Development.
