Budhi Gandaki flash flood likely caused by landslide dam breach, says Flood Forecasting Division

Summary

A sudden flash flood in the Budhi Gandaki River is suspected to have been triggered by a landslide dam breach, according to the Flood Forecasting Division. Officials issued repeated SMS and social media warnings as water levels surged and a bridge and monitoring station were swept away.

Key Points
  • The Flood Forecasting Division suspects a landslide temporarily blocked the Budhi Gandaki River before the accumulated water burst through and caused the flash flood.
  • Rainfall was minimal in the area over the previous 24 hours, making it an unlikely immediate cause of the sudden flooding.
  • Water levels at the Budhi Gandaki-Aarughat station rose sharply from 2.28 meters to 8.43 meters before the monitoring station and a bridge were washed away.
  • The division sent multiple SMS alerts and Facebook Live warnings to residents downstream, urging evacuation and caution in affected areas.
