- A lake is a body of surface water enclosed by land. Rivers may feed it or drain it, so a lake can take water from a river or act as its source.
- Lakes occur in hills, plains, plateaus, rift zones and along coasts. India’s main groups are the glacial lakes of the Himalaya, the fault-guided lakes of Kashmir and Kumaon, the salt lakes of Rajasthan and the lagoons of both coasts.
- Their uses include drinking water, irrigation, navigation, water storage, livelihood through fishing, and an effect on local climate.
Types and Special Forms
Types of Lakes
- The main types of lakes can be classified on several bases:
- By water: freshwater, brackish and saltwater lakes.
- By origin: natural and artificial lakes.
- Oxbow lake: formed by river deposits, where a meander is cut off.
- Crater lake: a hollow of volcanic activity or meteorite impact that fills with water. Lonar is of the impact kind.
Subglacial Lakes
- A subglacial lake is liquid water lying between an ice sheet and the land beneath.
- It stays liquid because the ice above acts as an insulator, trapping geothermal heat from the crust.
- Lake Vostok is the largest of the Antarctic subglacial lakes, whose known number was put at almost 400 in older counts.
- It lies at the southern Pole of Cold, beneath Russia’s Vostok Station, under the central East Antarctic Ice Sheet.
- The station stands 3,488 m above mean sea level.
- A global inventory of 2022 catalogues 773 subglacial lakes, most of them in Antarctica.


Lakes of India
Key Facts
| Feature | Lake | State or UT | Note |
|---|---|---|---|
| Largest freshwater | Wular | Jammu and Kashmir | Tectonic origin; area varies with season |
| Largest brackish lagoon | Chilika | Odisha | About 906–1,165 sq km; older figures 780–1,144 |
| Longest | Vembanad | Keralam | About 96.5 km; older figure 75 km |
| Largest inland salt lake | Sambhar | Rajasthan | About 225 sq km in the rains |

- Wular Lake, Jammu and Kashmir, is named the largest freshwater lake in India, and Chilika (Chilka) Lake, Odisha (Orissa), the largest saline water lake.
- Chilika is about 70 km long and up to about 22 km wide, narrowing to about 7 km in the south-west.
- It is the most heavily fished inland tract of the coast.
- Cholamu Lake, Sikkim, has long been listed as the highest lake in India.
- Vembanad Lake, Keralam (Kerala), is the longest lake. Kochi stands where it opens to the sea.
- Govind Ballabh Pant Sagar, behind the Rihand Dam, is the largest artificial lake in older lists. By storage, Indira Sagar on the Narmada is now the largest reservoir.
- Older accounts rank Dhebar Lake (Jaisamand) in Udaipur district of Rajasthan next after it.
- Salt lakes of Rajasthan: the inland drainage east of the Thar holds Sambhar, Didwana, Degana, Kuchaman, Sargol and Khatu.
- Sambhar lies about 65 km west of Jaipur at about 360 m, about 30 km long and 3–8 km wide, and it shrinks sharply in the dry season.
- Lagoons: the kayals of Keralam are shallow inlets parallel to the coast.
- Pulicat, about 40 km north of Chennai, is barred from the sea by the Sriharikota sand spit.
- Kolleru began as a shoreline lagoon. Growth of the Godavari–Krishna delta, about 35 km seaward, has since left it inland.
- Kashmir Valley itself was a Pleistocene lake, later filled with sediment. Naini Tal and Bhim Tal mark the Kumaon lake belt.
- Ramsar sites: India had 103 Ramsar sites as of 15 October 2026, when Sukhna Lake in Chandigarh and Sauj Jheel in Uttar Pradesh were added. The status marked below follows that list.

- On this map, “Chilka” is Chilika and “Hirakund” is Hirakud.

Important Lakes of the World
Which Water Bodies Count as Lakes
- The world’s largest lakes are usually listed leaving out the Caspian Sea, which is too big for most such lists, though it is still a lake.
- The Black Sea is not a lake, because the Bosporus and Dardanelles connect it to the Mediterranean.
- Many big rivers fall into it, so its surface salinity is about 17‰, half that of the ocean.
- The Caspian Sea and the Dead Sea are lakes.
Named Lakes
- Lake Baikal: a rift lake in southern Siberia, Russia, long and crescent-shaped.
- It is the largest freshwater lake by volume, holding 22–23% of the world’s fresh surface water, and the oldest (25–30 million years) and deepest, at 1,642 m (5,387 ft).
- It is seventh in the world by surface area. UNESCO listed it as a World Heritage Site in 1996.
- The land to its east is Transbaikalia, and the loose region around it is Baikalia.
- Baikal-GVD (Gigaton Volume Detector): one of the three largest neutrino detectors, with IceCube at the South Pole and ANTARES in the Mediterranean, launched by Russian scientists to trace these elusive particles and their sources.
- Lake Tanganyika: the longest lake in the world (660 km), and second in both volume and depth, after Baikal.
- Great Lakes of North America: interlinked freshwater lakes reaching the Atlantic through the Saint Lawrence Seaway.
- West to east: Superior, Michigan, Huron, Erie, Ontario. By size: Superior, Huron, Michigan, Erie, Ontario.
- Lake Superior is the largest continental lake by area, and Lake Michigan the largest wholly in one country.
- They are a major water corridor for bulk goods, through the Great Lakes Waterway.
- Dead Sea (Salt Sea): borders Jordan to the east, and Palestine and Israel to the west. Its surface and shores are Earth’s lowest land.
- Older accounts give 423 m and 418 m below sea level. It stands at about 430 m and is still falling.
- It is among the lakes with the highest salt concentration.
- Aral Sea: lay between Kazakhstan to the north and Uzbekistan to the south. It has shrunk since the 1960s, after Soviet irrigation projects diverted its rivers.
- African Great Lakes: part of the Rift Valley lakes in and around the East African Rift, including Lake Victoria, the largest in Africa, and Lake Tanganyika.
World Records
- Highest: the crater lake of Ojos del Salado (6,390 m) in the Andes, if size is ignored. The highest large lake is Pumoyong Tso (5,018 m) in Tibet.
- Highest commercially navigable: Lake Titicaca (3,812 m), on the Peru–Bolivia border and the largest in South America.
| Continent | Largest lake by surface area |
|---|---|
| Australia | Lake Eyre, a salt lake |
| Africa | Lake Victoria |
| Antarctica | Lake Vostok, subglacial |
| Asia | Lake Baikal, or the Caspian if counted, which is shared across Eurasia |
| Europe | Lake Ladoga, then Lake Onega, north-western Russia |
| North America | Lake Superior |
| South America | Lake Titicaca; Maracaibo, larger, is open to the sea |
| Rank, Caspian excluded | By surface area | By volume | By depth |
|---|---|---|---|
| 1 | Superior, North America | Baikal, Asia | Baikal, Asia |
| 2 | Victoria, Africa | Tanganyika, Africa | Tanganyika, Africa |
| 3 | Huron, North America | Superior, North America | – |
