 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.

Topography

As per a classification of the Himalayan Lakes done on the basis of their origin, there are four groups and Tsomoriri falls under the third group of “Remnant Lakes". The classification as reported states:

(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 Uttaranchal), (iii) Remnant lakes which were originally structural but represent the remnants of vast lakes (e.g., Tsomoriri, Tso Kar, Pangong Tso

Despite a poor vegetation cover, relatively low standing biomass and high anthropogenic pressure, this area sustains a considerably high livestock population.

, 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.

Access

The lake is located to the Southeast of Leh in Eastern Ladakh, Jammu & Kashmir, at a road distance of 215 kilometres (133.6 mi). Leh is also connected by Air with many destinations in India.

Hydrology and water quality

The Lake, draining a catchment area of 120 km² (46.3 sq mi) is enclosed by rolling hills of the Tibetan cold desert on the western side with steep hills and by the Pare Chu, which flows on the southern side. Another wetland, the Nuro Sumdo (with a catchment area of 20 km² (7.7 sq mi)), lies between Tsomoriri in the north, and the Pare Chu in the south, a bog which drains into the Pare Chu. Several small mountain streams feed the Lake notably through pasture land at Peldo Le. The lake is fed by springs and snow melt and has a maximum depth of 40 m (131.2 ft). Aridity and cold desert

. The justification could be summarized as:
  • The faunal collection is unique and has a large variety with endemic and vulnerable species
  • The herbivore species are also endemic to the region
  • The lake plays a fundamental role as breeding grounds and key staging posts on migration routes for several water birds belonging to six families, which is distinctive of wetland diversity and productivity

Threats to the lake

There are a number of threats to the Lake, such as:
  • Increase in the number of tourists visiting the lake affects breeding of avi fauna
  • Construction of a road right up to the Lake
  • Pasture degradation affecting wildlife, particularly wild herbivores (marmots, hares, ungulates)
  • An increase in the grazing of Sheep in the wetlands surrounding the Lake
  • The absence of a proper garbage disposal Facility at the Lake.
  • Dogs kept by the people who live near the lake are known to attack the cranes and destroy their eggs.
  • Jeep safaris have been known to chase wildlife such as Kiang

     and approach close to the breeding ground.
  • Lack of regulations and monitoring by the government.

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. The actions initiated in this direction are:

 near Tsomoriri 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 Tsomoriri as a ‘Sacred Gift for a Living Planet’ during the Annual Conference held in Nepal in November 2000.

Some of the other achievements so far reported on the Lake’s conservation are:
  • Regulation in consultation with local community Vehicular traffic flow and parking has been restructured with restriction of camping sites around the lake
  • The Indo Tibetan Border Petrol (ITBP), tour operators and local population have introduced regular garbage clean up operations
  • Korzok community living around the lake has voluntarily built traditional and social fencing around the wetland to protect breeding and feeding grounds from vehicular traffic
  • Tsomoriri Conservation Trust has been set up.
  • Twenty Nature Clubs have been registered in different schools in Ladakh

World Wildlife Fund’s (WWF) role

World Wildlife Fund for Nature — India (WWF-India) is spearheading the efforts at conservation of the Tsomoriri 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 the main activities planned for the Tsomoriri and other wetlands in Ladakh regions are:

The Promotion of Nature Conservation and Environmental Protection as the Basis for Sustainable and Equitable Development.
  • Evolve plan to establish a Sustainable Tourism Model managed by Local Communities at Tsomoriri
  • Carry on with the biological and socio-economic surveys around selected wetlands and document for future reference
  • Organize capacity building training programmes for Tour operators, Army, Teachers and local communities
  • Frequent education and awareness Programmes for various target groups
  • Management Planning for Tsomoriri and also Tsokar and Pangong Tso lakes by involving major stakeholders
  • To set guidelines for introducing Eco-Tourism Certification Scheme in Ladakh
  • To mobilise financial resources to carry out a comprehensive Strategic Environment Assessment
  • Develop Environmental Management Systems, implement and certify the Environment Management Systems with special focus on tourism sector
  • Maintain and enhance existing field presence at Tsomoriri, Leh, and Tsokar and increase presence at Chushul and Hanle marshes as well to achieve better results
