Glacial Lake Outburst in Bhutan Triggers Flood Alerts in India
IN · Published Oct 30, 2026
• A significant glacial lake outburst flood (GLOF) occurred in Bhutan, releasing approximately 7.4 million cubic metres of water from the Shintaphu Lake.
• The water surged through the Mo (Mofu) river system towards the Sankosh river, raising flood concerns in northern West Bengal and Assam.

Impact & Risks

The outburst poses a significant threat to communities in northern West Bengal and Assam, with potential damage to homes, infrastructure, and livelihoods. The steep Himalayan terrain exacerbates the risk, as water released at high altitudes can gain momentum and cause destructive flooding downstream. Hydropower projects, roads, and bridges in the region are particularly vulnerable to the debris-laden torrents. The incident underscores the broader risks posed by climate change, including glacier retreat and the increasing frequency of extreme weather events, which heighten the likelihood of such disasters.
