Sunita SomvanshiA flash flood in Nepal’s Bhote Koshi River prompted heightened vigilance downstream in Bihar as authorities monitored the Gandak and neighbouring flood-prone areas.
On August 26, 2026, at 8:40 a.m., a massive flood struck the Bhote Koshi River in Rasuwa District, Nepal. Heavy loss of life and property was reported, with severe impacts in riverbank areas of Rasuwa, Nuwakot, Dhading and Gorkha.
The same day, Bihar’s Chief Minister Samrat Choudhary convened a high-level review after learning of flash-flood conditions in Nepal’s upper catchment. Officials were concerned that rapidly rising water could increase flow in the Gandak River, which flows into Bihar. The Chief Minister directed all officials to remain fully alert and monitor river levels continuously.
On August 27, the Chief Minister conducted an aerial survey of the Gandak and flood-prone border areas, travelling from Sonpur to Valmikinagar. Officials reviewed current conditions and assessed preparedness at key points like the Valmikinagar Barrage.
By August 31, the situation had intensified. Multiple river gauges across Bihar were above warning or danger levels, including Gandak stations at Bagaha, Khadda, Dumariaghat and Lanjh, as well as other major river systems. The Bihar government continued heightened preparedness and monitoring operations in potentially affected districts including West Champaran, East Champaran, Gopalganj, Saran, Muzaffarpur and Vaishali.
Authorities coordinated relief, rescue and safety measures in flood-affected areas. People living near the Gandak River, in low-lying areas, and in flood-prone zones remained alert to water levels and official updates.
For current river levels and flood information, check official government health and emergency databases for real-time gauges and daily bulletins, along with statements from the Bihar Chief Minister’s office and State Disaster Management Authority. Local news outlets and government advisories provide additional real-time information on conditions and evacuation procedures if needed.
