A torrential flash flood swept through the Bhote Koshi River on Wednesday, killing at least 98 people [5] across central Nepal.
The disaster underscores the extreme vulnerability of mountain communities to sudden geological collapses, which can wipe out critical infrastructure and entire villages in minutes.
The flood originated on the Nepal-Tibet border after heavy rains triggered a sudden collapse of mud and rock or an avalanche [3, 4]. The resulting surge of water and debris tore through the Bhote Koshi River, impacting the districts of Rasuwa and Dhading before spreading to Nuwakot and Chitawan [1, 2].
Death toll reports vary significantly across sources. While some early reports indicated at least eight deaths [6], later updates state that 95 bodies have been recovered [1, 2, 4] and at least 98 people were killed [5].
The environmental impact has devastated local infrastructure. At least 12 hydropower projects were affected [7], and four permanent bridges were damaged [7]. The surge destroyed villages and left hundreds of people missing [5].
Rescue operations are ongoing in the affected districts. The disaster follows a pattern of increasing instability in the region, where the combination of steep terrain and heavy seasonal precipitation creates a high risk for mudslides and flash floods [3].

The disparity in death toll reports—ranging from eight to 98—reflects the chaos of initial rescue efforts in remote Himalayan terrain. The destruction of hydropower projects and permanent bridges suggests a long-term economic blow to the region, as these assets are critical for both local energy stability and national infrastructure.
