At least 469 people have been confirmed dead and more than 1,300 remain missing after flash flooding struck Nepal’s Rasuwa, Nuwakot, and Dhading districts on August 26. Officials say the death toll is expected to rise, and authorities have declared the affected areas disaster crisis zones for the next three months. CARE Nepal is working with government and local partners to get emergency assistance to the families most affected.

“The flooding has left affected families without homes, possessions, and livelihoods, and has raised concerns about the spread of waterborne diseases due to damaged water and sanitation infrastructure,” says Mona Sherpa, CARE Nepal‘s country director.

The flood hit shortly before 9 a.m., as many children were walking to school. Scientists at the International Centre for Integrated Mountain Development (ICIMOD) say an ice-and-rock avalanche blocked the Lhende Khola, releasing a sudden surge downstream. The precise cause is still disputed and investigations are ongoing.

“The Lhende Khola has flooded twice in 14 months, this time triggered by an ice-and-rock avalanche from a glacier on the Nepal side that blocked the river and released a sudden surge downstream,” said Saswata Sanyal, a disaster risk reduction specialist at ICIMOD. A barrier lake formed by debris from the initial landslide broke its banks on August 28, briefly halting rescue efforts in both Nepal and China over fears of a second flood. Authorities have warned residents in at-risk areas to move to higher ground.

The damage is already extensive. Officials have confirmed that 32 bridges and nearly 25 miles of road were swept away, including the entire road from Betrawati in Nuwakot to the Rasuwagadhi border crossing, which links Tibet to Nepal. The worst-hit settlements include Timure and Syaphrubesi, near the border that supports much of the trade and tourism between Nepal and China. The flood affected 14 hydropower and solar projects, with a combined capacity of about 748 megawatts.

A wide channel of grey mud and rubble runs between damaged buildings in a Rasuwa settlement, with a truck and other vehicles stranded in the debris and people watching from the balconies of a partly built concrete structure.

The number of people missing has climbed steadily as communications are restored to cut-off settlements. As of August 28, the Nepal Police report that at least 700 of the missing are foreign nationals and another 466 people have been injured. Security personnel, hydropower workers, customs and immigration staff, and trekking guides are also among those still unaccounted. It is important to note that many missing persons cases reflect downed phone networks rather than confirmed deaths.

Rasuwa district is still rebuilding from the 2015 earthquake. Hundreds of families displaced by that earthquake had resettled on the low-lying banks of the Trishuli River. One such community of 250 households has now been swept away entirely, Sherpa says, based on reports from CARE’s partners in the area.

How CARE is responding to the Nepal flash floods

“Relief efforts prioritize those most in need, particularly women, girls, older people, and people with disabilities, who are often hit hardest in the aftermath of a disaster like this,” says Sherpa.

Beyond the immediate rescue, communities face challenges around shelter, food, safe water, health services, protection, and ways to earn a living again. Older people, children, and people with disabilities face those risks differently. To address this, CARE is carrying out a rapid assessment of how the flood and displacement are affecting women and girls in different ways.

At the same time, CARE is working with the National Disaster Risk Reduction and Management Authority (NDRRMA), local partner organizations, and Humanitarian Partnership Platform members to reach affected communities with essential support. Some of CARE’s partner organizations include Community Self Reliance Centre, Community Development Centre Nepal, Manekor Society Nepal, and Sahayatri Samaj Nepal.

Reaching people is the most difficult aspect of the response so far. Washed-out roads and destroyed bridges have left the worst-affected communities extremely difficult to reach, especially in Rasuwa.

“The access, be it road and communication, all those things are very difficult,” says Sherpa.

CARE is ready with hundreds of CARE PACKAGE® for Emergencies kits. Each contains five types of support: solar panels for light and charging electronics, tarpaulins and shelter materials, water purification supplies, hygiene items, and kitchen utensils with ready-to-cook and ready-to-eat food. CARE has also sent relief items alongside government distributions to the areas that can be reached.

More than 100 packages have been handed over to the NDRRMA and the Prime Minister’s Office for distribution. The Nepal Army is transporting these supplies to Dhunche, Rasuwa, as additional emergency supplies are mobilized. Families staying in temporary shelters urgently need ready-to-eat food. Longer-term, they will need transitional housing.

CARE Nepal is working directly with authorities to help coordinate the national response. A further 290 community volunteers trained in emergency preparedness are on standby, working alongside the Federal Response Team led by the Prime Minister Relief Committee.

“Our immediate focus is to coordinate closely with the government authorities, humanitarian clusters, and also the local partners so that there is no duplication,” Sherpa says. “The first hours of a disaster are often characterized by incomplete information, and so those who need the right kind of support will not receive it.”

More than 10,000 households along the Trishuli corridor need emergency shelter and relief supplies. Humanitarian organizations are still working out the full scale of what people need.

Recovery from the Nepal flash floods will take time

Crowds of people walk along a paved road lined with trees and concrete buildings toward a wide expanse of grey flood debris in the distance, with green hills and clouds beyond.
Residents make their way along a road toward the flood-hit stretch of the valley, where mud and debris now cover what was a settlement. Clearing the damage and rebuilding roads, homes, and water systems will take months.

Sherpa is clear that this is more than an emergency. The flood has cut the only overland route linking Kathmandu to Tibet. On the Tibetan side, the Gyirong Port, which handled nearly a third of trade between Nepal and China in 2024, took the direct force of the floodwaters. Disease is a further risk as floodwaters recede and water and sanitation systems remain damaged.

Drawing on CARE’s work after the 2015 earthquake, Sherpa says, “A longer-term engagement will be required, as the flood will make it harder for people to earn a living, travel, trade, and rebuild local businesses.”

The Government of Nepal has asked both India and China for help with the rescue effort. The Nepali Army, Armed Police Force, and Nepal Police have been deployed for search and rescue.

“We need your solidarity and support at this point,” Sherpa says.
