Most of the freshwater lakes of India are located in the Himalayan region. The lofty ranges of the Himalayas are snow covered and have many glaciers. Glacial activity results in the formation of circular hollows lip in the mountains. They are known as Cirques. The melting of the glacial snow in later period forms cirque lakes. As the lakes have water from snowmelt they are freshwater lakes, e.g., Pangong lake in Ladakh.
Tectonic activity in the Himalayan region also results in the formation of depressions. They are filled with melting snow forming lakes of tectonic origin, e.g., the Wular Lake in Jammu and Kashmir, which is the largest freshwater lake in India.
The Dal Lake of Srinagar, Bhimtal and Nainital of Uttarakhand, Loktak Lake of Manipur and Barapani Lake of Meghalaya are some other important freshwater lakes. All are located in the Himalayan region and the Purvanchals.
