Flash Flood Ravages Communities Along Nepal’s Budhi Gandaki River
By Drooid · · How we work
Core Event
Heavy rains triggered a landslide at Chumnubri (also reported as Chumchure) in Gorkha district, temporarily damming the Budhi Gandaki River. The blockage burst, sending a sudden surge of water, mud and debris downstream on Sunday. The flash flood swept away homes, suspension bridges and part of a hydro-electric construction site, prompting the National Disaster Risk Reduction and Management Authority (NDRRMA) to order evacuations along the riverbanks.
Background & Context
The Budhi Gandaki is a tributary of the Trishuli River, a key waterway near Kathmandu. Nepal is still recovering from catastrophic floods in August that struck border towns with Tibet, killing more than 1,400 people and leaving thousands missing. Those earlier floods have heightened concern over the region’s vulnerability to landslides and glacial melt events.
Data & Statistics
- Missing persons: At least five people (two women and three men) are reported missing.
- Rescues: The army and other rescue teams have saved roughly 49–82 individuals, including nine foreign nationals.
- Housing damage: Reports vary—one source cites about a dozen houses destroyed, another mentions three dozen, and a third notes 65 houses swept away across Gorkha and Dhading districts.
- Infrastructure loss: Two to four suspension bridges were washed away, and a hydro-electric project camp lost construction equipment.
- Communication loss: A hydrological monitoring station was swept away, cutting off real-time river data.
Official Statements & Responses
- The NDRRMA issued a social-media alert urging residents of Gorkha, Tanahun, Chitwan, East Nawalparasi and West Nawalparasi districts to relocate to safer areas.
- The Nepalese army confirmed that helicopters and ground troops continued rescue operations, having evacuated dozens of villagers by Sunday afternoon.
- Dharmendra Kumar Mishra, the senior bureaucrat for Gorkha district, said, “We have asked villagers living along the riverbanks downstream to evacuate and remain safe.”
- Binod Parajuli, a government meteorologist, reported that the loss of the hydrological station has halted data collection from the affected site.
On-the-Ground Reports
Local official Laxmi Gurung described the scene: “The flood looked similar… It was very scary, and it still feels like a nightmare for us.” She added that her house was destroyed, leaving her without electricity, though she confirmed no casualties in her immediate area.
Conflicting Reports & Gaps
- Cause of the flood: While the Nepal Army and several officials attribute the surge to a landslide that blocked the river, other observers suggest an ice-avalanche may have contributed. The exact trigger remains unverified.
- Extent of damage: Sources differ on the number of houses destroyed (dozen, three dozen, or 65) and the count of bridges lost (two to four). No comprehensive assessment has been released.
- Casualty figures: All reports agree that no deaths have been confirmed, but the status of the missing persons remains uncertain.
Why It Matters
The flash flood underscores the ongoing risk of secondary disasters in Nepal’s mountainous regions, especially as climate-induced extreme weather intensifies. Damage to critical infrastructure—bridges, power lines and a hydro-electric project—could impede recovery efforts from the August floods and affect energy supply in the coming months. The loss of river-monitoring equipment also hampers early-warning capabilities, potentially increasing vulnerability to future events.
