Weeks after Nepal floods showed Himalayan glacial lake outburst floods are now annual, Uttarakhand has installed its first glacial lake early-warning system in Vasundhara Tal, Chamoli. [GLOFs]
Chief Secretary Anand Bardhan flagged off team for high-altitude lake. At 4,800m, Vasundhara Tal is Category A - high risk. The system, supported by National Disaster Management Authority and Wadia Institute of Himalayan Geology, includes automatic weather station, water level sensor, and siren.

ISRO and Central Water Commission have identified 188 glacial lakes in Uttarakhand, 13 high risk. In August, Tharali in Chamoli saw flash flood from glacial lake, Bhagirathi river system swelled, 2 dead. In 2023, Sikkim's South Lhonak GLOF killed 55.
The challenge is power and connectivity - system is solar powered, with satellite telemetry. It will monitor fluctuations and give 90-minute warning to downstream villages. Surveys establish bathymetry, depth, loose moraine stability.

For Himalayan states, this is adaptation, not prevention. Climate change is making glaciers melt faster, forming unstable lakes. Uttarakhand's model, if works at Vasundhara, will be replicated in 12 more lakes.
