Tso Moriri, also known as Lake Moriri, is a beautiful "Mountain Lake" located in the high Changthang Plateau of Ladakh, India. This area is like a "northern plain" in the mountains. The lake and its surroundings are a special protected area called the Tso Moriri Wetland Conservation Reserve.

The lake sits very high up, at about 4,522 m (14,836 ft) above sea level. It is the largest high-altitude lake completely within Ladakh and India. The lake is about 26 km (16 mi) long from north to south and 3 km (1.9 mi) to 5 km (3.1 mi) wide.

Tso Moriri does not have any rivers flowing out of it. Its water is a bit salty, but you might not notice it by taste. The lake gets its water from melting snow in the nearby mountains and from natural springs. Most of the water comes from two main stream systems, which also have large marshy areas where they meet the lake.

It's usually easiest to visit the lake during the summer. However, the village of Korzok on the northwest shore and some military bases on the eastern side are lived in all year round.

Exploring Tso Moriri

The village of Korzok is a great place for visitors. It offers places to stay with local families, a Buddhist monastery, and activities related to the lake. Many tourists visit between May and September. Even though there are mostly tent camps and a small guesthouse, people still come to enjoy the beauty.

How Tso Moriri Was Formed

Lakes in the Himalayan mountains can be grouped by how they were made. Tso Moriri is a "remnant lake." This means it was once part of a much larger lake that formed due to movements in the Earth's crust. Over time, parts of that huge lake dried up, leaving behind lakes like Tso Moriri.

The Changthang Plateau, where the lake is, is a high-altitude area. It's an extension of the western Tibetan plateau and sits over 4,500 m (14,800 ft) high. This unique environment is home to many rare animals and plants. The lake's basin is a closed drainage basin, meaning water stays within it and doesn't flow out to rivers or oceans.

The lake is surrounded by tall mountains, some rising over 6,000 m (20,000 ft). These include Mentok Kangri and Lungser Kangri. The main people living here are the "Changpa" (or Champa). They are nomadic shepherds of yak, sheep, goat, and horses. They originally came from Tibet and use the valley for grazing their animals and for farming.

The Korzok Monastery, which is 400 years old, is on the western side of the lake. It attracts both tourists and Buddhist pilgrims. Northeast of Tso Moriri, there is a smaller lake known locally as the Lake of Joy.

Getting to the Lake

Tso Moriri is located southeast of Leh in eastern Ladakh. It's about 240 kilometres (150 mi) away by road, and the road is mostly in good condition. You can also reach Tso Moriri directly from Pangong Tso through the remote Changtang region. This drive is considered one of the most beautiful in all of Ladakh.

It's important to carry enough fuel because there are no petrol stations between Pangong Tso and Tso Moriri, which is about 235 kilometres (146 mi) away. Leh is also connected to many cities in India by air.

Water Features

The lake covers an area of about 120 km2 (46 sq mi). It is surrounded by peaks taller than 6,000 m (20,000 ft) on both its east and west sides. To the south, a flat valley connects to the Pare Chu river, but water does not flow between them.

Several small mountain streams feed the lake, including one that flows through pasture land. The lake gets its water from springs and melting snow. Its deepest point is about 40 m (130 ft). The area around the lake is a cold desert. In summer, temperatures range from 0° to 30 °C (32° to 86 °F). In winter, it can get very cold, from −10° to −40 °C (14° to -40 °F).

Animals and Plants

A study of the lake and its nearby Nuro Sumdo wetland in 1996 found many different animals and plants.

Plants of Tso Moriri

While the deepest parts of the lake have no plants, the shallow areas have Potamogeton species. The marshy areas have many types of sedges and reeds, like Carex, Caragana, and Astragalus species. These plants are typical of the dry, steppe-like environment around the lake.

Other plants found include:

  • Primula (a low-growing herb)
  • Pedicularis (a parasitic plant)
  • Juncus thomsonii
  • Leontopodium species
  • Tiny floating plants called phytoplankton, like Oocystis and Cyclotella (a type of diatom).
  • Pastures for domestic animals to graze.

Ramsar Wetland Site

Because of its amazing variety of animals and plants, Tso Moriri was named a Ramsar Wetland site in November 2002. This means it's recognized internationally as a very important wetland.

The reasons for this include:

  • It has unique and rare animal species.
  • Many plant-eating animals found here are special to this region.
  • The lake is a vital breeding ground and resting stop for many water birds during their long migrations. This shows how rich and productive the wetland is.

Tso Moriri faces several challenges that threaten its natural beauty and wildlife:

  • More tourists visiting the lake can disturb the birds during their breeding season.
  • New roads being built near the lake can also affect the environment.
  • Too much grazing by sheep in the wetlands can harm the plants and animals.
  • There isn't a good way to dispose of garbage at the lake, which can cause pollution.
  • Dogs kept by people living near the lake sometimes attack cranes and destroy their eggs.
  • Jeep safaris sometimes chase wild animals like kiangs and get too close to breeding areas.
  • There aren't enough rules or monitoring by the government to protect the lake.

Conservation Efforts

People and organizations are working hard to protect the delicate ecosystem of Tso Moriri. Here are some of the things being done:

  • Tso Moriri is officially a Wetland Reserve, and hunting wildlife is against the law.
  • The State Department of Wildlife has set up a checkpoint near Mahe Bridge to monitor visitors entering the lake area.
  • WWF-India (World Wildlife Fund – India) has an office in Korzok to help protect the high-altitude wetlands in Ladakh. They conduct surveys, talk to tourists, and teach locals about conservation.
  • The Wildlife Institute of India has a research station in Leh to study the region.
  • Nature clubs have been started, and information booklets about the lake have been published.
  • Thanks to WWF-India's efforts, the local community declared Tso Moriri a "Sacred Gift for a Living Planet" in 2000.
  • Traffic and parking around the lake have been reorganized, and camping sites are now limited.
  • The Indo Tibetan Border Patrol (ITBP), tour operators, and local people regularly clean up garbage.
  • The community in Korzok has built fences to protect the breeding and feeding grounds from vehicles.
  • A Tso Moriri Conservation Trust has been created.
  • Twenty Nature Clubs have been registered in different schools in Ladakh.
  • The Indian Army has promised to help set up a Nature Interpretation Centre in Leh.

WWF's Role in Conservation

The World Wildlife Fund for Nature – India (WWF-India) is leading many efforts to protect Tso Moriri lake and the wider Ladakh region. WWF has been working here for over 30 years. Their main goal is to promote nature conservation and environmental protection to help the area develop in a fair and lasting way.

Some of their key activities for Tso Moriri and other wetlands in Ladakh include:

  • Creating a plan for sustainable tourism that local communities can manage.
  • Continuing to study the animals, plants, and human communities around the wetlands.
  • Training tour operators, army personnel, teachers, and local communities about conservation.
  • Running regular education and awareness programs for different groups of people.
  • Developing management plans for Tso Moriri, Tsokar, and Pangong Tso lakes with the help of all involved parties.
  • Setting guidelines for an Eco-Tourism Certification Scheme in Ladakh.
  • Finding money to carry out a detailed environmental assessment.
  • Developing and putting into practice Environmental Management Systems, especially for the tourism sector.
  • Keeping and expanding their presence at Tso Moriri, Leh, and Tsokar, and increasing their presence at Chushul and Hanle marshes to achieve better results.
