Suspected Glacial Lake Outburst Triggers Devastating Flash Flood in Rasuwa; Hydropower, Trade Route, and Downstream Settlements Hit
RASUWA — A massive flash flood tore through the Bhotekoshi and Trishuli river corridors on Wednesday morning, causing widespread devastation across settlements, critical infrastructure, and vital transit routes in Rasuwa district.
The sudden deluge struck around 8:00 AM despite no rainfall being recorded at the district headquarters, leading local authorities to suspect a Glacial Lake Outburst Flood (GLOF) originating upstream in Tibet.
Key Developments & Impact:
-
Settlements Affected & Evacuation Alerts: The floodwaters battered settlements including Timure, Syafrubesi, and the historic town of Betrawati. High-alert evacuation warnings have been issued across five downstream districts—Rasuwa, Nuwakot, Dhading, Gorkha, and Chitwan (all the way to Narayanghat).
-
Severe Energy Disruption: Over 10 hydropower projects along the river basin have suffered severe damage or shutdown. Major facilities, including the 111-MW Rasuwagadhi, Chilime, and Trishuli-3A plants, have halted power generation.
-
China Trade Route Blocked: Operations at the key Rasuwagadhi border point have come to a standstill, raising concerns over festive supply chains ahead of Dashain.
-
Trekking Routes Disrupted: Thousands of trekkers along the Langtang and Gosaikunda pilgrimage routes have been stranded or affected.
Emergency teams and government officials are actively coordinating disaster response and assessing the full scale of structural damage.
