KATHMANDU, Aug 28: A catastrophic flash flood along the Nepal-China border has left hundreds dead and more than 1,400 people missing, while authorities are now monitoring a newly formed barrier lake that could trigger another disaster downstream.
The scale of the tragedy continues to emerge as rescue teams search remote and mountainous areas affected by the massive surge of water, mud and debris. According to the latest reports, Nepal has recorded 469 deaths, while Chinese authorities have separately reported fatalities on the Tibetan side of the border. The number of missing people includes a large number of foreign nationals, with Indian citizens among those yet to be traced.
The disaster struck after a glacial collapse triggered devastating flooding in the Himalayan border region, sweeping away homes, roads, bridges and other infrastructure. The flood also affected areas used by trekkers and travellers, including people travelling towards the Mount Kailash region.
New Barrier Lake Creates Another Threat
Even as search and rescue operations continue, authorities have raised concern over a barrier lake that has formed near the Nepal-China border.
China’s Ministry of Water Resources said the lake, located near the confluence of the Chhochen Khola and Purepu Tsangpo rivers, was already overflowing. It was estimated to contain around 2 million cubic metres of water, with another 3 million cubic metres expected to enter the lake over the following three days, increasing the risk of a breach.
A breach could send a fresh surge of water into downstream areas connected to the Bhote Koshi river system, adding another layer of danger to communities already affected by the flooding. Authorities in both Nepal and China are monitoring the situation and assessing possible emergency measures.
Search for Missing Continues
Rescue personnel, including security forces and emergency teams, are continuing operations in difficult terrain. The Nepal government has also established an emergency mechanism to coordinate information, search efforts and consular assistance for foreign nationals affected by the disaster.
The government has reportedly declined offers from several countries to deploy their own search-and-rescue teams, saying Nepal’s security agencies are capable of handling the operation. Instead, Kathmandu has sought financial assistance through a centralised or “one-door” mechanism, with additional support expected to be required during the rehabilitation and reconstruction phase.
The situation remains highly fluid, with casualty and missing-person figures expected to change as rescue teams gain access to more affected areas and authorities verify reports.
