Safe water and sanitation
Flood damage can interrupt drinking-water and sanitation systems. Prioritize official WASH guidance, hygiene supplies and verified restoration needs.

October flood response · August disaster recovery
Nepal’s river valleys need clear information—and careful help.
A new flash flood struck the Budhi Gandaki corridor on 11 October while recovery continues after the separate 26 August Rasuwa–Bhote Koshi disaster. The dated reports below distinguish the new response from earlier recovery decisions and needs assessments.

ICIMOD’s preliminary advisory identifies a possible landslide-dam breach near Chumchet. The trigger and extent of damage remained under investigation; this is a separate event from August’s flood.

Associated Press — rescue update, 12 October 2026 ↗AP reported the government’s decision to end search and rescue for the August disaster and focus on rehabilitation. It does not describe October’s new emergency.

NDRRMA Situation Report #30 — 20 September 2026 ↗NDRRMA reported that 2,027 affected households in holding centres were surveyed for temporary housing needs; 397 were in Rasuwa. This is a dated needs survey, not a full impact census.

Human priorities
Start with the people closest to the problem.
Access and continuity
Damaged roads, bridges, electricity and communications isolate mountain communities and health services. Offline-capable information matters.
Children and separated families
Family tracing and child protection require trained organizations, strict consent and minimal data—not public lists of names or locations.
Bounded open-source work
Build around accountable response—not around vulnerable people.
Access-map verification
Help trusted mapping teams validate damaged routes and bridges from public imagery. Mark uncertainty and never route people into hazard zones.
Low-connectivity information
Package verified notices for SMS, print and intermittent connections, with Nepali-language review and an explicit publication time.
Needs and restoration tracking
Prototype aggregated, non-personal tracking for water systems, clinics and shelters using humanitarian standards such as HXL.
Privacy-preserving reunification
Support recognized protection actors with consent-led workflows. Never publish survivor identities, children’s records or precise locations.
