On 26 August 2026, a glacier collapsed in the high mountains of Nepal, unleashing a flood that swept away homes and infrastructure and left 1,457 people dead. The tragedy set a grim backdrop for the region, highlighting the vulnerability of communities living near glacial valleys.
Chumnubri village is located in Gorkha district, Nepal. The village includes houses, bridges, and a hydropower project that were affected by the flood.
Houses, Bridges Swept Away In Nepal Flash Flood Months After Deadly Disaster https://t.co/Hvg5wOefqr https://t.co/takNkInJ2U
Early on 11 October 2026, the river’s gauge recorded a height of 3.66 metres at 6:30 AM. Within a little over two hours, by 8:40 AM, the water had climbed to 8.43 metres, far surpassing the established danger mark of five metres.
The force of the water also carried away the river’s measurement centre, including the bridge that housed the gauges.
Authorities were quick to note that the deluge was not driven by rainfall. Instead, preliminary observations pointed to a temporary blockage in the river channel that later gave way, releasing a sudden wall of water. The National Disaster Risk Reduction and Management Authority (NDRRMA) said the flood resulted from a suspected river blockage and breach.
🚨🌊 Catastrophic flooding in Nepal yet again. A flash flood on the Budhi Gandaki early this morning swept away about 35 to 40 homes in Gorkha, and a local official says around 150 more were flooded downstream at Arughat. Six bridges are gone, 10 people are missing, and army helicopters have airlifted villagers out. https://t.co/P1uqm8dwjl
The surge destroyed more than thirty houses, swept away several bridges, and damaged the local hydropower project. The force of the water also carried away the river’s measurement centre, including the bridge that housed the gauges.
Because the measurement centre was washed away, officials could not continue to collect real‑time data from the site. NDRRMA remarked that "since the flood also washed away the measurement center, including the bridge, further details could not be obtained," leaving a gap in the immediate technical record.

In the aftermath, the Nepal Army joined NDRRMA in search and rescue operations. Teams combed the affected area, and residents in low‑lying zones were advised to move to higher ground as a precaution against any further surges.
So far, no casualties have been reported from the October flash flood. The absence of loss of life contrasts with the August disaster, which caused 1,457 deaths.
NDRRMA said that, based on satellite images and early observations, it estimates the river was blocked and then breached, causing the sudden flood. The authority added that "detailed technical analysis of the actual cause of the incident is ongoing," indicating that work to understand the precise mechanics continues even as the waters recede.
