Quick Summary

A glacial lake outburst flood (GLOF) from Shintaphu Tsho in Bhutan’s Gasa district on October 29, 2026, caused significant damage to roads and infrastructure, including washing away a Bailey bridge built two years ago with Indian government support. The flooding created an artificial lake near Taktsemakhang that officials are closely monitoring for potential further outburst danger. No human casualties have been reported, but neighboring Assam’s Dhubri and Kokrajhar districts remain on high alert due to the flood's impact downstream.

Story summary

A glacial lake outburst flood (GLOF) caused by Shintaphu glacial lake bursting its banks on October 29, 2026, has washed away infrastructure in Gasa Tshachu, a natural hot spring in Bhutan's Himalayan region. Two Bailey bridges and parts of the road to Laya village were destroyed, making the area impassable indefinitely. While no injuries or loss of life have been reported, concerns remain over another potential outburst due to an artificial lake near Taktsemakhang, which could cause further damage downstream. Bhutan’s Prime Minister Tshering Tobgay and Industry, Commerce and Employment Minister Namgyel Dorji are monitoring the situation in affected districts like Punakha. West Bengal has issued high-alert warnings for residents along the Sankosh River to prepare for potential impacts from the flood.
