Nepal flash floods destroy homes and bridges along Budhi Gandaki River

A sudden rise in the Budhi Gandaki River brought destructive flash flooding to Nepal's Gorkha district on October 11. NDTV reported that flooding struck Chumnubri village after the river's water level increased.

The speed of the rise was striking. According to Adnkronos, the water level at one point climbed from two metres to almost 8.5 metres within a couple of hours.

The trigger is not established in the supplied reports. Business Line said the cause of the sudden surge remained unclear.

On October 11, floodwater swept away buildings along the river, Al Jazeera reported. Times Now described thick, dark mud and debris surging through Gorkha, destroying houses and bridges and damaging a hydropower project.

The losses were concentrated in particular riverside communities. Mint reported that nearly 35 houses in the Painyu and Bagar areas of Chumnubri Rural Municipality's Ward 3 were swept away, along with six bridges.

As the flooding spread, residents evacuated settlements in north central Nepal, according to The Hindu. News18 reported that government alerts prompted evacuations in Arughat, a riverside community.

Helicopters were also used to evacuate residents, Sky News reported. Euronews said rescuers were working to reach people affected by the floods.

The reported toll remains unsettled. Mint reported ten people missing, while Times of India put the number at at least ten. Euronews reported five missing and 45 houses swept away. Those accounts do not provide a single agreed count of missing people or destroyed homes.

Warnings have been issued for settlements along the Budhi Gandaki River, according to The Indian Express. The emergency comes as Nepal is still recovering from catastrophic floods less than two months earlier, which BBC News reported left thousands dead and missing.

The immediate questions are whether rescuers can locate those reported missing and whether further evacuations are needed along the river. Helicopter evacuations and rescue efforts have been reported by Sky News and Euronews, but the supplied coverage gives no final outcome.

The cause of the surge also remains an open question, according to Business Line. Updated assessments will be needed to reconcile the differing reports of missing people and homes lost.
