Due to growing concerns about the impact of https://exam.pscnotes.com/Climate-change”>Climate Change on Himalayan Glaciers, the Ministry of Jal Shakti has released an updated Atlas of Glacier Lakes, which are part of the Ganges River Basin.
In the Ganga basin, approximately 4,707 Glacial lakes have been mapped.
A similar exercise was carried out for the Indus River basin in December 2020.
The current study used Resourcesat-2 (RS-2) Linear Imaging Self Scanning Sensor-IV (LISS-IV) satellite data to map glacial lakes with a water spread area greater than 0.25 ha.
Glacial lakes are classified into nine types, which are further divided into four categories based on the process of lake formation, location, and type of damming material.
The mapped area extends from the Ganga River’s orgin to the Himalayan foothills, covering a catchment area of 2,47,109 square kilometres.
The study of the Ganges River Basin partially covers India and a part of the transboundary area.
