KATHMANDU, August 26, 2026 — Nepal’s catastrophic Bhote Koshi flood has grown into one of the country’s most devastating natural disasters in recent years, with 157 bodies recovered by late Wednesday night, hundreds of people still unaccounted for and preliminary infrastructure losses estimated at more than Rs 200 billion.

The disaster began Wednesday morning when an enormous surge of water, ice, rock and debris entered Nepal through the Bhote Koshi river system in Rasuwa near the Tibet border before racing downstream through the Trishuli River corridor.

According to the latest police figures released late Wednesday, 64 bodies had been recovered in Chitwan, 27 in Dhading, 22 in Nawalparasi East, 19 in Gorkha, 13 in Nuwakot, nine in Tanahun and three in Rasuwa, bringing the confirmed Nepal death toll to 157.

The discovery of so many victims far downstream highlights the extraordinary force of the flood. Bodies swept away from the upper river corridor have been recovered scores of kilometres from the initial disaster zone, and authorities warn that the final death toll could rise substantially as rescue teams gain access to isolated areas.

At least 28 Nepal Police personnel remain out of contact, according to the latest police update. Earlier consolidated disaster reports also listed dozens of Nepal Army and Armed Police Force personnel as unaccounted for. The National Disaster Risk Reduction and Management Authority reported that 85 security personnel — 44 soldiers, 28 Nepal Police personnel and 13 Armed Police Force members — were out of contact in its earlier assessment.

Police said 41 injured people were receiving treatment in hospitals, including 20 at Tribhuvan University Teaching Hospital, nine at Trishuli Hospital, four at the National Trauma Centre, three at Bir Hospital and others at military and private hospitals. A broader disaster-authority assessment had recorded 55 injured, indicating that the numbers are still being reconciled as the emergency evolves.

The international dimension of the disaster is also becoming increasingly serious. The Nepal Tourism Board says 403 tourists and travellers remain unaccounted for, including 341 foreign nationals and 62 Nepalis. The list includes 203 men and 200 women.

India has the largest number of nationals on the list, with 133 Indians, followed by 47 Americans, 34 Australians, 33 British citizens, 24 Canadians and 19 Malaysians. Ukrainians, South Africans, Singaporeans, Japanese, New Zealanders and citizens of several other countries are also listed. The Tourism Board says nationals from more than 25 countries were travelling through the affected region, many toward Kailash Mansarovar or Gosaikunda.

Officials have stressed that being “unaccounted for” does not mean all those listed are confirmed flood victims. Telecommunications, electricity and road networks have collapsed in several affected areas, leaving families, tour operators and authorities unable to establish contact.

Other government tallies have cited higher figures — including 484 tourists or pilgrims out of contact — reflecting overlapping lists compiled by government agencies, travel companies and security bodies. The Tourism Board’s later tally of 403 is therefore currently the more specific tourism-sector figure, but authorities are still reconciling the lists.

The scale of physical destruction is enormous. A late-night assessment by Nepal’s disaster authority reported damage to 35 motorable bridges and 45 suspension bridges — 80 bridges in total — along with around 40 kilometres of major roadway.

The Department of Roads separately reported devastating damage along the roughly 40-to-42-kilometre Betrawati–Rasuwagadhi corridor, effectively severing Nepal’s principal overland commercial link with China through Rasuwagadhi.

Physical Infrastructure Minister Sunil Lamsal has put the preliminary infrastructure damage alone at more than Rs 200 billion, cautioning that the estimate could rise considerably once detailed technical assessments include bridges, highways, energy facilities, customs infrastructure and other public assets.

The Rasuwagadhi customs complex has been devastated. Business representatives estimate that around 200 containers of imported goods were inside the customs yard, while hundreds of trucks, containers, electric vehicles and other vehicles were caught in the flood. Many of the goods had been imported ahead of Nepal’s festival season.

The destruction of the customs facility and road corridor is expected to disrupt cross-border trade, government revenue and supply chains for an extended period.

Nepal’s energy industry has suffered an equally severe blow. According to the Energy Ministry and Nepal Electricity Authority, 12 operating power-generation facilities with combined capacity of 431.1 megawatts have been forced out of the national system. Another 15 projects under construction, representing about 470 megawatts, have sustained damage.

Together, 27 operating and under-construction energy projects representing roughly 901.1 megawatts of capacity have been affected.

Affected facilities include Rasuwagadhi, Chilime, Sanjen, Upper Sanjen, Langtang Khola, Upper Trishuli-3A, Mailung, Trishuli and Devighat, along with substations, transmission towers and distribution networks. The 220-kV Trishuli-3B Hub substation has also suffered severe damage.

The Nepal Electricity Authority has reported more than 196 employees and workers associated with hydropower plants and electricity infrastructure out of contact, making the energy sector one of the areas of greatest concern in the ongoing search operation.

Nepal’s banking industry has also been hit. The Nepal Bankers’ Association says nine commercial bank branches were destroyed or severely damaged, while 26 employees working at eight affected branches remained out of contact in the latest sectoral assessment.

Glacier and rock collapse emerges as leading explanation

Scientists are still investigating the exact cause of the catastrophe, but satellite imagery has strengthened the theory that the disaster was triggered by a massive ice-and-rock avalanche high in the Himalayas rather than by conventional monsoon flooding.

Experts examining satellite imagery told Reuters that a large section of glacier at an elevation of roughly 5,200 metres collapsed and plunged more than 1,200 metres into the valley below, releasing or displacing a destructive mixture of ice, rock, sediment and water into the river system.

A 4.4-magnitude seismic event was recorded in the border region around the time of the disaster. Scientists are examining whether the tremor contributed to destabilising the glacier and rock mass, although no definitive causal link has yet been established.

Nepalese and Chinese meteorological authorities have also said that no significant rainfall was recorded that could explain a flood of this magnitude. Nepal and China have since agreed to strengthen real-time exchange of meteorological and hazard information, while further investigation continues into the source of the avalanche and the possibility of additional upstream instability.

The flood has also damaged agricultural land, livestock facilities, food storage areas and local markets. Authorities are preparing animal-health surveillance amid fears that contaminated water, displaced livestock and deteriorating sanitation could create secondary disease risks.

The government has warned businesses against exploiting disrupted supply chains. Traders found creating artificial shortages, hoarding essential goods or imposing unjustified price increases on food, medicines, fuel and other necessities could face legal action.

Meanwhile, international assistance has begun arriving. India dispatched 10 tonnes of humanitarian relief materials and essential medicines on Wednesday night, following a telephone conversation between Indian Prime Minister Narendra Modi and Nepalese Prime Minister Balendra Shah.

China has also pledged assistance, while Nepal and China are coordinating more closely on upstream monitoring. The Nepal government has declared affected local areas in Rasuwa, Nuwakot and Dhading disaster crisis zones for three months, ordered free treatment for the injured and prioritised rescue, shelter, food, electricity, communications and the reconstruction of essential infrastructure.

The World Bank has also indicated to Nepal’s Finance Ministry that up to Rs 25 billion could potentially be mobilised from different sources for emergency assistance, while Nepal continues discussions with foreign governments and development partners over rescue and reconstruction financing.

For now, however, the human toll remains the greatest concern.

Hundreds of tourists, security personnel, bank employees, hydropower workers, customs personnel and local residents remain out of contact. Entire settlements have been cut off, communications remain unreliable and rescue teams are continuing to search along the Bhote Koshi, Trishuli and Narayani river systems.

With 157 bodies already recovered in Nepal, the government has warned that figures for the dead, injured and missing remain provisional and could change sharply as communications are restored and search teams reach areas that remain inaccessible.

The disaster is also likely to leave a profound economic legacy. Once losses to highways, bridges, hydropower, customs, tourism, banking, agriculture, private homes and businesses are fully assessed, the overall economic cost could rise well beyond the preliminary Rs 200 billion infrastructure estimate.

What began as a sudden surge in a remote Himalayan river has, within hours, become a national humanitarian and economic catastrophe — and the full scale of the tragedy is still emerging.
