Sikkim Identifies 40 High-Hazard Glacial Lakes, 16 at Highest Risk
IN · Published Sep 4, 2026
Sikkim has flagged 40 glacial lakes as high-hazard sites, with 16 categorised as being at the highest risk of a Glacial Lake Outburst Flood (GLOF).
The state is using satellite imagery and remote sensing to monitor these lakes and has developed lake-specific mitigation plans.

Impact & Risks

The identified high-risk glacial lakes pose a significant threat to downstream communities and infrastructure, including roads, bridges, and hydropower projects. Past GLOF events, such as the October 2023 disaster that killed 60 people, highlight the potential for catastrophic damage. The risks are exacerbated by the rapidly changing Himalayan landscape, which is leading to the formation and expansion of glacial lakes.
