Heavy floods in the Bagmati River triggered flood warnings for Bihar's Darbhanga, Sitamarhi, and Muzaffarpur districts on August 6-7, 2026, following heavy rainfall in Nepal's upstream catchment areas and water releases from Nepalese dams. The Bihar Flood Alert System warned of embankment breach risks. The Bagmati River originates near Kathmandu Valley in Nepal and drains into the Ganga in Bihar. North Bihar is perennially affected by floods from rivers originating in Nepal — including Kosi, Gandak, Bagmati, and Mahananda. India and Nepal have bilateral river management agreements for the Kosi and Gandak rivers.
