Overview
- Hours after Thursday's glacier collapse in Nepal, a sudden debris-filled surge moved down the Bhote-Koshi/Trishuli system into the Narayani-Gandak and pushed rapid flows toward India.
- The Central Water Commission and NDRF issued real-time warnings and monitored discharges while sharing updates with state disaster teams in Bihar and eastern Uttar Pradesh.
- Operators opened all 36 sluice gates at the Valmikinagar barrage and released large volumes of water, with flow peaking near 1.5 lakh cusecs before falling to about 1 lakh cusecs by Thursday afternoon.
- State teams evacuated roughly 5,000 families to higher ground, set up shelters and medical camps, deployed NDRF, SDRF and SSB units, and recovered multiple bodies swept downstream into Maharajganj and other border areas.
- Officials say the immediate flood threat has eased as river levels recede but survival of debris in the channel, recovered bodies and the risk of renewed surges from upstream blockages mean continuous cross-border monitoring and readiness remain essential.
