Flash Floods in Nepal Sweep Away Houses and Bridges, 10 Missing

A sudden rise in the Budhi Gandaki River in Gorkha District, Gandaki Province, swept away at least 35 houses and six bridges on Saturday, leaving ten people missing. Rescue teams recovered six survivors, but the full number of casualties remains unknown as searches continue in remote valleys.

Local officials said heavy rainfall in the upper catchment triggered the flash flood. Villagers downstream received little warning. Several bridges that connect isolated settlements to the main road network were destroyed, isolating communities until temporary crossings can be built.

The Budhi Gandaki is a tributary of the Gandaki River system. It drains steep Himalayan slopes where intense monsoon and post-monsoon rains can produce rapid runoff. Saturday’s event follows a pattern of increasing flash floods in the mid-hills as rainfall intensity rises.

Nepal’s disaster management authorities have ordered evacuations in low-lying areas further downstream. Helicopters and ground teams are searching the river corridor. Access remains difficult because several road sections are blocked by debris.

The missing include residents of villages along the river. Families have gathered at higher ground. Local government offices are compiling lists of those unaccounted for, but communication with some hamlets is still cut.

This is not the first major flood on the Budhi Gandaki in recent years. Similar events in 2024 and 2025 destroyed infrastructure and displaced hundreds. Reconstruction of bridges has lagged behind the frequency of damage.

Climate data for the region show an increase in extreme precipitation days. The combination of steep topography, loose soil and expanding settlements near riverbanks raises the risk. Nepal’s National Disaster Risk Reduction and Management Authority has listed Gorkha among districts with high flash-flood exposure.

International aid agencies operating in Nepal have not yet issued formal appeals. Local Red Cross volunteers are distributing temporary shelter materials. The provincial government has asked for additional helicopters from the Nepal Army.

The destroyed bridges served both foot traffic and light vehicles. Their loss will delay the movement of food and medical supplies into the upper valleys until temporary Bailey bridges or cable crossings are installed. Engineers estimate several weeks for permanent repairs once the water level drops.

No official death toll has been released. Authorities say they will update figures once the search of the riverbed and side valleys is complete. The ten missing persons are the only confirmed gap in the current count.

Residents in the affected villages have moved livestock and remaining belongings to higher slopes. Some have taken shelter in school buildings. The district administration has set up a control room in Gorkha Bazaar to coordinate relief.

The event occurs during the transition out of the main monsoon. Residual moisture in the atmosphere can still produce heavy convective rainfall. Forecasts for the coming days show continued unsettled weather in the central hills.

Nepal’s road network in the mid-hills remains vulnerable to such events. Many bridges were built decades ago to older design standards. Recent government plans to raise bridge clearances and add early-warning sensors have not yet reached all high-risk rivers.

The search continues. Families of the missing are waiting for confirmation. The six people rescued so far have been taken to local health posts for treatment of minor injuries and exposure.
