What happened
A glacial lake outburst flood (GLOF) occurred in Bhutan, first reported on Thursday at Shintaphu Lake in Gasa district. The resulting surge of water has caused the Sankosh River water level to rise by nearly one and a half meters in West Bengal. Authorities in West Bengal have evacuated over seven thousand people from vulnerable areas along the river.
Why it matters
The GLOF has led to severe damage to infrastructure, including a section of the Punakha-Gasa Secondary National Highway and a Solar Irrigation Lifting System. The incident has prompted alerts in parts of West Bengal and Assam over potential flash floods, impacting regional connectivity and agricultural supply.
The Central Water Commission issued a flood advisory for Dhubri as floodwaters moved downstream through the Sankosh River following a GLOF in Bhutan.
