The lake has been formed due to boulders and debris obstructing the river flow. Work to remove the blockage has already begun, and the water level is receding," said NK Joshi, district disaster management (DDMO) officer, Chamoli. While immediate risk from this particular temporary lake appears to be diminishing, experts warn that the broader threat posed by glacial lakes and the potential for glacial lake outburst floods (GLOFs) in Uttarakhand remains high, especially during and after the monsoon and summer seasons. Uttarakhand has previously witnessed devastation linked to such events.
