Nepal Floods Kill 469 as Barrier Lakes Threaten New Deluge
A huge flood hit Nepal near the border with Tibet on Wednesday.
Water, mud and rocks rushed down the mountains and destroyed homes, roads, bridges and power projects.
Nepal says 469 people have died, but reports disagree about how many people are still missing.
Many missing people were tourists or pilgrims traveling through the mountains.
Scientists think a glacier collapse or ice-and-rock avalanche started the disaster.
The rushing water also piled up debris and made new lakes behind natural dams.
These lakes are filling with more water and could burst, causing another flood.
China stopped some rescue work because the area was too dangerous, while Nepal continued looking for survivors.
Rescuers also tried to reach people trapped in a hydropower tunnel.
Nepal reported 469 deaths after flash floods and debris flows struck on Wednesday.
Reports differ on the number missing, ranging from nearly 1,000 to more than 1,500, including foreign tourists and pilgrims.
A glacial collapse or ice-rock avalanche sent water, mud and debris downstream from Tibet into central Nepal.
Debris-blocked rivers formed barrier lakes holding about 2 million cubic metres of water, with another 3 million expected.
China paused rescue operations because of renewed-flooding risks, while Nepal continued searches and helicopter efforts.
- Who
- At least 469 people died in Nepal; nearly 1,000 to more than 1,500 people were reported missing across Nepal and Tibet, including foreign nationals.
- What
- Flash floods and debris flows destroyed settlements and infrastructure and created a continuing risk of further flooding from barrier lakes.
- When
- The disaster struck on Wednesday, with rescue operations continuing on Friday, August 28, 2026.
- Where
- The floods affected central Nepal and areas along the Nepal-Tibet border, including Rasuwa, Dhading, Nuwakot and Tibet's Gyirong County.
- Why
- Reports attributed the flooding to a glacial collapse or ice-rock avalanche that sent water and debris downstream; debris dams then formed rising barrier lakes.
Nepal-Led Response
International Assistance
Foreign rescue teams
Nepal-Led Response
Nepal's foreign ministry said its security agencies were conducting search and rescue and that foreign rescue assistance was not currently required.
International Assistance
Other countries offered help, and United States President Donald Trump said Washington had offered support and would provide whatever assistance Nepal wanted.
Cause of the disaster
Nepal-Led Response
Some initial accounts linked the seismic signal to an earthquake, while Nepali experts suspected an avalanche or glacial collapse blocking the Lhende River.
International Assistance
The United States Geological Survey later said the signal was generated by a glacial collapse and debris flow rather than an earthquake.
Rescue operations amid renewed risk
Nepal-Led Response
Nepal continued searches, deployed helicopters and security personnel, and attempted to rescue about 100 people trapped in a hydropower tunnel.
International Assistance
China paused its rescue operation and ordered teams to stand by because authorities considered renewed flooding too dangerous.
- Reported death toll
- Nepal reported 469 deaths; three additional deaths were reported in Tibet.
- Missing people

- Nepal reported 1,545 injured or stranded people rescued, 84 people under treatment in Kathmandu, and 7,451 security personnel deployed.
- Barrier-lake threat
- About 2 million cubic metres of water had accumulated in a debris-blocked lake, with another 3 million cubic metres expected over three days.
- China's response
- China evacuated more than 1,000 people from Gyirong County, including 555 tourists, and paused rescue operations because of renewed-flooding risks.
- Potential reconstruction cost
- Businessman Binod Chaudhary estimated that rebuilding Nepal's infrastructure could cost at least $5 billion.
