The flash flood that struck Chumnubri village in Gorkha district on Sunday, Oct 10 2026, lifted the Budhi Gandaki River from 3.66 metres to a devastating 8.43 metres in just ten minutes, wiping out more than 35 homes and several bridges.
The surge followed a sudden breach of an upstream blockage, a phenomenon the National Disaster Risk Reduction and Management Authority (NDRRMA) says was not rain‑induced, but likely the result of glacial meltwater and debris piling against the riverbanks.
The flood lands in the same valley that swallowed 1,457 lives in August's glacier‑triggered torrent, reminding residents of the lingering threat from the Himalayas.
The Nepal Army, airlifted by helicopters and ground convoy, has dispatched a Composite Quick Reaction Team from Kathmandu, already retrieving six survivors from Jagat and conducting aerial reconnaissance.
When the NDRRMA warned residents to stay away from the riverbank, a local family of five fled to a higher ridge, but their home was lost to the mud‑laden floodwaters, leaving them homeless.
Authorities plan a full hydrological study and will convene a disaster committee meeting on Thursday, Oct 13 2026, to assess infrastructure damage and future mitigation.
