Starting 20th August to 10th September 2025, over 35 experts from six top national institutes (CWC, CWPRS, NIH, GSI, DGRE, NIDM, Sikkim University) and six state government departments, the Army, ITBP and the local community are trekking to the icy heights of Mangan district to assess and study 6 high-risk glacial lakes.
Using cutting-edge tech—ERT surveys, bathymetry, UAV 3D terrain mapping—they will assess the hazard of the lakes, GLOF modelling, design retention structures and plan Early Warning Systems. These studies will form the basis of mitigation proposals to safeguard downstream communities from disasters like the 2023 South Lhonak glacial flood. A team of 5 senior officials from Himachal Pradesh Disaster Management Authority are also joining for an exposure-cum-field training. This is science in action, resilience in motion
