Important Notes — Lakes & Wetlands
Overview of Lakes in India
Lakes are inland water bodies that play a crucial role in maintaining ecological balance, providing irrigation, and supporting biodiversity. In India, lakes are categorized based on their origin, salinity, and water source.
Classification and Key Types
- Freshwater Lakes: Most freshwater lakes are located in the Himalayan region. They are primarily of glacial origin (formed by the digging of basins by glaciers). Examples include Wular Lake (Jammu & Kashmir), which is the largest freshwater lake in India by surface area.
- Saltwater/Saline Lakes: Predominantly found in arid and semi-arid regions. The Sambhar Lake in Rajasthan is the largest inland saline lake in India, vital for salt production.
- Lagoon Lakes: Formed by the deposition of sandbars along the coastline. Chilika Lake (Odisha) is the largest brackish water lagoon in India and was the first site to be included in the Ramsar Convention list (1981).
- Man-made Lakes: Created for hydroelectric power and irrigation purposes, such as Govind Sagar (on the Sutlej River, behind the Bhakra Nangal Dam).
Important Exam Facts
- Lonar Lake: Located in Maharashtra, it is a crater lake formed by a meteor impact. It is known for its unique saline and alkaline ecosystem.
- Loktak Lake: Situated in Manipur, it is famous for Phumdis (heterogeneous masses of vegetation, soil, and organic matter). It hosts the Keibul Lamjao National Park, the world's only floating national park.
- Vembanad Lake: Located in Kerala, it is the longest lake in India.
Wetlands and Conservation Status
Wetlands are transition zones between terrestrial and aquatic ecosystems, often referred to as the "kidneys of the landscape" due to their water-purifying properties.
The Ramsar Convention
- The Ramsar Convention on Wetlands is an international treaty for the conservation and sustainable use of wetlands, signed in 1971 in Ramsar, Iran.
- India became a signatory in 1982.
- As of 2024, India boasts 80 Ramsar Sites, one of the largest networks of such sites in South Asia.
- World Wetlands Day is celebrated globally on February 2nd every year.
Significant Wetland Features
- Montreux Record: A register of Ramsar sites where changes in ecological character have occurred or are likely to occur. Currently, Keoladeo National Park (Rajasthan) and Loktak Lake (Manipur) are listed under the Montreux Record.
- High Altitude Wetlands: India has several protected high-altitude wetlands, such as Tso Moriri and Tso Kar in Ladakh, which are critical for migratory birds.
- Ecological Importance: Wetlands act as sponges that absorb excess rainfall, reducing flood risks, and serve as vital habitats for migratory species like the Siberian Crane.

*Note: For UPSC/SSC aspirants, focus on map-based locations of Ramsar sites and their specific river basins or states. Frequently asked questions often revolve around the largest, highest, and most recently declared wetland sites.*
