The rapid release of water from the Birpur barrage on the Kosi river in Supaul and the Valmikinagar barrage on the Gandak river in West Champaran has caused concerns about potential flooding in 14 districts. Heavy rainfall in the catchment areas of north Bihar rivers in Nepal and the local basins is the primary cause of this threat. Water discharge at the Birpur barrage increased from 4.80 lakh cusecs at 10am to 5.31 lakh cusecs by 2pm, while at the Valmikinagar barrage, it rose from 3.84 lakh cusecs to 4.49 lakh cusecs during the same period. The Kosi river joins the Ganga river at Kursela in Katihar district, while the Gandak river is located north of Patna in Saran district, suggesting that Bhagalpur and Katihar could be severely affected by the floodwaters. The Supaul district administration has advised residents between the eastern and western Kosi embankments to move to higher ground as a precautionary measure. The state water resources department has issued a high alert to the relevant district magistrates, instructing them to be prepared and monitor embankments closely. Official leaves have been cancelled, and it is predicted that the water discharge at the Birpur barrage could reach 6.81 lakh cusecs, nearing the highest level recorded 56 years ago. Similarly, the discharge at the Valmikinagar barrage may reach a two-decade high. The 14 districts on high alert include Supaul, Saharsa, Khagaria, Bhagalpur, and Katihar due to the rising Kosi river, as well as West Champaran.The districts of Champaran, East Champaran, Gopalganj, Sitamarhi, Sheohar, Muzaffarpur, Saran, Vaishali, and Samastipur are experiencing flooding from the overflowing Gandak river. Additionally, the Bagmati river is also causing significant flood risks in the districts of Sitamarhi, Sheohar, and Muzaffarpur among others.
