Lakes

  • There are numerous lakes in India.  
  • Thes e differ in terms of size and other characteristics.
  • Some lakes are formed by the action of glaciers and ice sheets , while others are formed by wind, river action, and human activity.
  • A m eandering river across a floodplain forms cut-offs that later develop into ox-bow lakes
  • Spits and bars form lagoons in the coastal areas, e.g. the Chilika lake, the Pulicat lake, and the Kolleru lake. 
  • Lakes in the inland drainage region are sometimes seasonal , such as the saltwater Sambhar lake in Rajasthan.  
  • Sambhar lakes’ water is used for producing salt.
  • The Himalayan region contains the majority of freshwater lakes. 
  • They formed when glaciers carved out a basin that was later filled by snowmelt
  • The Wular lake in Jammu and Kashmir is the result of tectonic activity.
  • Wular lake is India's largest freshwater lake. 
  • Other significant freshwater lakes include Dal Lake, Bhimtal, Nainital, Loktak, and Barapani.
  • Aside from natural lakes, damming rivers for hydropower generation has r esulted in the formation of lakes such a s Guru Gobind Sagar (Bhakra Nangal Project).

Importance of Lakes

  • A lake helps to regulate the flow of a river.
  • It prevents flooding during heavy rains and helps to maintain an even flow of water during the dry season. 
  • Lakes can also be used to generate hydroelectric power. 
  • They help to maintain the aquatic ecosystem
  • It also enhances the natural beauty of the region, develop tourism , and provide recreational opportunities.
