A flash flood from the Bhote Koshi River swept through central Nepal on Wednesday, killing up to 157 people and leaving hundreds missing [1, 2].
The disaster highlights the extreme vulnerability of Himalayan communities to sudden glacial melt and heavy rainfall, particularly near the Tibet border where infrastructure is limited.
The flooding hit the Nuwakot and Dhading districts early Wednesday [3, 4]. Floodwaters surged from the Tibetan side of the border, causing the river to overflow and wash away entire settlements [5]. Verified videos showed dozens of people swept away at the border, a Reuters field reporter said [6].
Casualty reports vary as rescue operations continue. While some early reports cited eight deaths [7, 8], other sources state at least 95 people died [9]. The highest reported death toll currently stands at 157 [2]. Deputy Inspector General of Police Abinarayan Kafle said at least eight bodies have been recovered [8].
More than 400 people are missing [1]. This number includes a significant number of international tourists, including 105 Indians [1] and 33 Americans [10]. Rescue teams are currently searching for survivors among the debris of washed-away villages.
The floods caused extensive damage to the region's energy infrastructure. At least 12 hydropower projects were damaged by the surge [2]. Local residents and tourists were caught in the path of the water, which moved rapidly from the high-altitude border regions into the valleys.
Emergency responders are coordinating efforts across the two districts to locate the missing and stabilize remaining infrastructure. The surge is believed to have been triggered by a combination of heavy rain and glacial melt on the Chinese side of the border [5].
“At least eight bodies have been recovered.”
This event underscores the increasing risk of Glacial Lake Outburst Floods (GLOFs) in the Hindu Kush-Himalayan region. As temperatures rise, the stability of glacial lakes on the Tibet-Nepal border decreases, creating a persistent threat to downstream hydropower infrastructure and tourism hubs. The high number of missing foreign nationals likely complicates the diplomatic and rescue response, requiring coordination between Nepal, India, and the U.S.
