The freshwater lake built by India near its research station ‘Maitri’ in Antarctica is known as Priyadarshini. The lake is located at a distance of about 14 km from the Maitri station and has been built to facilitate freshwater supply to the station. It is named after the daughter of Rajiv Gandhi, Priyadarshini Gandhi. The lake is one of the unique features of India’s scientific presence in Antarctica and is a testimony to India’s capabilities in polar research and development. The lake is about 1.5 km long, 1 km wide, and 3-4 meters deep. It is fed by the melting snow from the surrounding area and is maintained through a special water management system. The lake is also an important source of information for scientists studying the geology and climate of Antarctica.
