A sudden, debris-filled flash flood tore down the Budhi Gandaki River in Nepal's Gorkha district early on Sunday, sweeping away dozens of homes and several bridges and leaving at least five people missing, according to officials and wire reports. Rescue teams, including Nepal Army helicopters, were still working to reach riverside settlements on Sunday as authorities warned people downstream to stay away from the river and move to higher ground.

The flood struck in the early hours, before most residents could react. Settlements along the river in northern Gorkha — including Salleri, Paiyuka and Jagat — were among the places hit, local officials told reporters. By Sunday afternoon the picture was still changing by the hour, with early counts of the damage overtaken by larger figures as reports arrived from remote villages that are difficult to reach even in normal times.
A River That Rose Without Warning
Residents in riverside settlements such as Chumling and Lokpa said they fled after hearing a loud roaring sound from the streams at around 4am, according to reporting by the Press Trust of India. Tourists staying in local hotels also ran for safety. One local ward chair described people leaving with almost nothing, saying families escaped as soon as they understood a flood was coming.
What made the surge especially frightening, residents said, was that it had not been raining. In darkness, people could hear the water stop and start again, but could not see whether a stream had been blocked or a slope had given way above them. Authorities used loudspeakers along the river to urge households to move to safer ground.
Gorkha's chief district officer, Dharmendra Kumar Mishra, said preliminary information pointed to a landslide above Siuribas. In the first official accounts, no deaths had been confirmed — a situation that changed as the day went on and search teams reached more of the affected area.
What the Latest Reports Say
By Sunday afternoon, the toll of destroyed property had grown sharply. A report carried by The Business Standard, citing UNB and the Associated Press, said the flood had swept away 65 houses across Gorkha and neighbouring Dhading district. Armed Police Force spokesperson Netra Bahadur Karki said five people were missing, all of them reported from Gorkha, and stressed that the collection of reports from the field was still ongoing.
The same reporting said two motorable bridges and two suspension bridges had been destroyed. Other accounts put the number of lost bridges higher, and officials also reported damage to a hydropower project in the district. Home Minister Sudan Gurung said a bridge linking Nyakchet and Philim bazaar in Chumnubri-3 was among those swept away.
The differing numbers are not unusual in the first day of a disaster in steep Himalayan terrain, where a single valley can be cut off when a bridge goes down. Officials in the district have been clear that the full extent of the damage is not yet known, and the figures published on Sunday should be read as a floor, not a final count.
The Landslide Dam Theory
Investigators are still working to establish exactly what triggered the surge, but the leading explanation offered by the Nepal Army points to a dangerous and familiar mechanism. According to the army's statement, a landslide in Chumnubri Rural Municipality temporarily dammed the Budhi Gandaki. When the river broke through the blockage, it released a sudden wall of water, mud and debris onto the settlements below.
Local residents had reached a similar suspicion on their own. Some believed the Syar stream, a tributary of the Budhi Gandaki between Lokpa and Chumling, may have been blocked before the flood arrived. The district administration has so far described the cause as unclear, and officials cautioned that the landslide theory remains preliminary.
Chumnubri's deputy chair, Laxmi Gurung, compared the morning's flood to the earlier Bhotekoshi flood in Rasuwa district, saying it had washed away dozens of houses and that the exact scale of the damage could not yet be stated. Events of this kind — sometimes called landslide-dam bursts — are among the hardest river disasters to warn against, because the river can fall quiet behind the blockage before rising violently within minutes.
Rescue by Air and on Foot
The Nepal Army said it airlifted 36 people to safer locations, and that search and rescue operations by security forces were continuing. Nepal Police, the Armed Police Force and local authorities were all mobilised, according to officials, while helicopters were deployed for rescue work, evacuations and relief distribution as the river continued to rise.
Nepal's disaster management authority warned people not to go near the Budhi Gandaki as far downstream as the Trishuli confluence until the flood had passed, and to stay in high places. Downstream communities were told to remain alert, because a river that has already broken one blockage can surge again if debris builds up a second time upstream.
For families who lost houses, the immediate needs are the familiar ones after a Himalayan flood: shelter, dry food, clean drinking water and a way to contact relatives in villages that may now be reachable only on foot. With bridges gone, even villages that escaped the water can be stranded for days.

What This Means
Sunday's flood is a reminder of how exposed riverside settlements in Nepal's hill districts remain to sudden water events that arrive without the warning that rainfall usually provides. Houses, small markets and hydropower works are often built close to rivers in narrow valleys, because flat land near water is the only land available. When a slope fails into a river upstream, that closeness becomes a liability in minutes.
It also underlines a gap in early-warning systems. Rain gauges and weather forecasts can flag a storm days ahead, but a landslide dam can form and fail overnight, in the dark, with no rain falling at all. Monitoring of unstable slopes and blocked tributaries, and loudspeaker-and-siren networks of the kind used on Sunday morning, may matter as much as weather forecasting for valleys like the Budhi Gandaki.
The damage to bridges carries its own long tail. Suspension and motorable bridges are lifelines in Gorkha: they carry children to school, patients to clinics and goods to market towns. Losing several in one morning means some communities will depend on helicopters and porters until temporary crossings can be built.

What Happens Next
Search operations for the five missing people are expected to continue, and officials say updated damage assessments will follow as teams reach settlements that were cut off on Sunday. The district administration has advised everyone living along the river to stay vigilant and to relocate to safer areas if water levels rise again.
Attention will also turn to the hydropower damage and to whether further landslides threaten the same stretch of river. If the blockage explanation is confirmed, engineers and geologists will need to check whether debris still dams any tributary upstream, because a second release would endanger both residents and rescuers.
For now, the verified picture is of a valley hit hard in the space of a few early-morning hours: dozens of homes gone, bridges down, at least five people unaccounted for, and a rescue effort racing to map a disaster whose full size, officials admit, is still unknown.
