Rescue workers continued to sift through mud and debris in areas devastated by a flash flood along the Nepal-China Himalayan border on Friday, while authorities warned that a newly formed lake could cause additional flooding. Nepal police said all security personnel, rescue workers and members of the public involved in relief efforts must remain on high alert and relocate to safe locations if necessary. Chinese state broadcaster CCTV released satellite images showing the lake formed near the site of a glacial detachment on Wednesday, with its barrier located about 10 km from Gyirong Port, the border crossing that was inundated by mud and water. The lake sits at an elevation of 2,950 m, roughly 1,000 m above Gyirong Port. It holds several million cubic meters of water, equivalent to about 1,200 Olympic-sized swimming pools, and is situated in a valley with limited elevation drop toward downstream regions. Climate scientists said the glacial collapse created multiple small water bodies, and the lake’s natural barrier may fail, producing a sudden downstream flood. Experts noted that ongoing glacial melt and accumulated debris heighten the risk, though a flood of the same magnitude as the Wednesday event is unlikely.
