Lakes in India: Types, Distribution, Importance, Major Lakes and Conservation

Lakes in India: Lakes are land-locked water bodies of standing water which have a significant role in freshwater resources and ecological balance in India. Lakes serve different purposes, including drinking water, irrigation, groundwater recharge, flood moderation, fishery and biodiversity conservation facilities, recreation and tourism, according to the MoEFCC (Ministry of Environment, Forest and Climate Change) & NPCA (National Plan for Conservation of Aquatic Ecosystems). They provide habitat for migratory birds and freshwater species, while also supporting the livelihoods of local communities. Spread across its diverse geographical areas, India has natural lakes (glacial, tectonic, oxbow, lagoon and freshwater lakes) as well as artificial lakes and reservoirs; for sustainable planning of water resources management and conservation of the environment, they are vital.

Types of Lakes in India

Indian lakes, as per the Ministry of Environment, Forest and Climate Change (MoEFCC), National Wetland Atlas (ISRO) & National Centre for Earth Science Studies (NCESS) are divided into various types based on their origin, namely tectonic lake, glacial lake, oxbow lake, lagoon (coastal) lake, crater lake & artificial reservoir.

Tectonic Lakes

• • Created from tectonic actions such as faulting and folding of the Earth’s crust.
  • Often very deep and permanent freshwater.
  • Distributed only in the Himalayan region
  • Support fisheries, biodiversity, and tourism.
  • Act as important freshwater reservoirs.
  • Provide habitat for migratory birds.

• E.g: Wular Lake (Jammu & Kashmir)

Glacial Lakes

• • Created by melting glaciers or glacial erosion

  • Horseshoe-shaped freshwater lakes.
  • Widespread in the plains of Ganga and Brahmaputra.
  • Recharge groundwater.
  • Rich fishing grounds.
  • Important wetlands.

• Example: Kanwar Lake (Bihar).

Lagoon (Coastal) Lakes – Lakes in India

• • Created when seawater becomes separated from the ocean by sandbars or spits
  • Usually contain brackish water.
  • Rich in biodiversity.
  • Support fisheries and aquaculture.
  • Protect coastlines.
  • Major bird habitats.
• E.g. Chilika Lake; Pulicat Lake; Vembanad Lake

Salt Lakes

• Contain saline water because evaporation is higher but a low drainage.
• Scattered across the drylands.
• Your faithful sources of salt and minerals.
• Support specialised flora and fauna.
• Attract migratory birds.
• Economically significant.
• Examples: Sambhar Lake, Didwana Lake.

Freshwater Lakes

• Get Accept The Water From Rainfall Or Spring Or River.
• Low salinity.
• It is a source of drinking water and irrigation.
• Rich in aquatic biodiversity.
• Support fisheries.
• Important wetlands.
• Examples: Loktak Lake, Wular Lake.

Crater (Impact/Volcanic) Lakes

• Created in volcanic craters or meteorite craters.
• Rare in India.
• Scientifically important.
• Support unique ecosystems.
• Popular geotourism sites.
• Protected for geological value.
• Example: Lonar Lake (Maharashtra).

Artificial (Reservoir) Lakes

• Created by damming rivers.
• Collect water for irrigating your plants and drinking
• Generate hydroelectric power.
• Help control floods.
• Support fisheries and tourism.
• Essential for water resource management.
• They include: Gobind Sagar, Hirakud Reservoir, Nagarjuna Sagar Reservoir

Urban Lakes – Lakes in India

• Located within or around cities.
• Recharge groundwater.
• Improve urban microclimate.
• Store stormwater.
• Support biodiversity.
• Important recreational spaces.
• For example: Hussain Sagar (Hyderabad), Upper Lake (Bhopal)

Floodplain Lakes – Lakes in India

In the case of floodplains, these are made each year when rivers overflow their banks in the spring thaw.

• Recharge groundwater.
• Moderate floods.
• Rich in fish diversity.
• Support agriculture.
• Important wetlands.
• Examples — Deepor Beel (Assam), Kanwar Lake (Bihar)

Man-made Tanks and Village Lakes – Lakes in India

• Constructed to harvest rainwater.
• Commonly distributed over southern and western India.
• Used for irrigation.
• Recharge groundwater.
• Supply drinking water.
• Support local biodiversity.
• Like: Veeranam Lake, Tamil Nadu; Bhojtal or Upper Lake in Bhopal

Significance of Lakes in India

• Freshwater Source: Lakes supply water for domestic, drinking, irrigation and industrial uses; important aspect of global freshwater security in dry periods.
• Aquifer Replenishment: Lakes promote percolation of precipitation, refilling aquifers and sustaining groundwater levels in adjacent areas.
• Biodiversity Hotspots: They can conserve biodiversity by providing habitats for fish, amphibians, reptiles, aquatic plants and migratory birds.
• Flood mitigation: Lakes are nature’s water body storage space, and during the monsoon, rainwater that cannot be absorbed in the ground naturally flows into lakes, which help to reduce the chances of flooding.
• Climate Regulation: Larger lakes help to regulate local temperatures, raise humidity levels and influence the regional microclimate — in turn promoting stability of environmental factors.
• Economic Value: Lakes have fisheries, aquaculture, agriculture, hydropower, transportation and tourism, providing millions of livelihoods around lakes.
• Ecological Benefits – They help in the trapping of sediments, filtering pollutants, and cycling nutrients to improve water quality—thereby supporting healthy aquatic ecosystems.
• Cultural and Spiritual Significance: Numerous lakes in India have connections with temples, festivals, and pilgrimage sites, contributing to the richness of India’s cultural values; externally, an important aspect of North Indian spiritual heritage.
• Recreation and Tourism: Lakes draw people for boating, birdwatching, watersports, photography and nature tourism that can boost local economies.
• Disaster Resilience and Sustainability: Healthy lakes increase drought resilience, sustainable water management, and climate change adaptation by providing surface storage of water and maintaining ecosystem balance.

Government Initiatives for Lake Conservation in India – Lakes in India

Several measures have been initiated by the Ministry of Environment, Forest and Climate Change (MoEFCC), Ministry of Jal Shakti and other government ministries for conservation and restoration of lakes throughout India. Key initiatives include:

• National Plan for Conservation of Aquatic Ecosystems (NPCA): One integrated scheme for conservation and management of lakes and wetlands, including pollution abatement, restoration, biodiversity conservation and community participation.
• Wetlands (Conservation and Management) Rules, 2017: The Wetlands Conservation and Management Rule, 2017 provides an immediate regulatory framework for the protection, wise use of wetlands and lakes in India.
• National Wetland Inventory and Assessment (NWIA): Remote sensing-based national wetland and lake map, monitor, and database built by ISRO, etc.
• This important initiative aims to facilitate the conservation and sustainable management of Ramsar Sites, which include many important lakes. Also Read: Amrit Dharohar Initiative: The guiding principles for conservation of wetlands
• Namami Gange Programme: Restoration of lakes, wetlands, and water bodies associated with the Ganga basin by means of pollution abatement and ecosystem restoration.
• Atal Mission for Rejuvenation and Urban Transformation (AMRUT): For costing urban lakes, stormwater management and environmental remediation of urban water bodies
• Jal Sakti Abhiyan — Catch the Rain: Promotes community participation in lake restoration, rainwater harvesting, watershed management and groundwater recharge.
• Ramsar Convention: Certain lakes in India are acknowledged as Ramsar Wetlands of International Importance, which are covered under global commitments for their conservation.

Major Environmental Issues Affecting Lakes in India

• Water Pollution: Lake water quality is compromised by untreated sewage, industrial effluents and agricultural runoff.
• Eutrophication: A high concentration of nutrients enriches planktonic plant life, causing an increase in the water and thereby leading to a reduction of dissolved oxygen, which negatively affects both aquatic animals and humans.
• Illegal Construction and Land Reclamation: Reduces the area of lakes’ shrinkage, Disrupt the natural drainage.
• Solid waste dumping Contaminates lakes and adversely affects biodiversity via plastic and municipal waste.
• Invasive Alien Species: An example would be the water hyacinth, which decreases oxygen levels and impedes water flow.
• Siltation: The accumulation of sediments from soil erosion in the lake, which reduces its depth and storage capacity.
• Over-exploitation: Excessive withdrawal, whether for domestic purposes, industrial use, or agricultural purposes, causes the lowering of the water table.
• Biodiversity loss – Habitat degradation: This puts pressure on native fish, aquatic plants, and migratory birds.
• Climate Change: Increasing temperatures and fluctuating precipitation modify lake hydrology and ecosystem function.
• Land Use: Deforestation and unplanned urbanisation increase runoff, erosion, and pollution entering lakes, driven by non-sustainable land use cover.
