Patna, Madhubani, and Motihari are facing concerns about potential flooding due to a significant increase in water discharge through the Birpur barrage on the Kosi river in Supaul and the Valmikinagar barrage on the Gandak river in West Champaran. This heightened risk is a result of heavy rainfall in the catchment areas of north Bihar rivers in Nepal and their own basins. The water discharge through the Birpur barrage increased from 4.80 lakh cusecs to 5.31 lakh cusecs, and through the Valmikinagar barrage, it rose from 3.84 lakh cusecs to 4.49 lakh cusecs on the same day. Concerns are particularly raised for Bhagalpur and Katihar districts as the Kosi river merges into the Ganga river at Kursela in Katihar district and the Gandak river flows north of Patna in Saran district. The Supaul district administration is urging residents between the eastern and western Kosi embankments to relocate to higher ground as a precautionary measure. The state water resources department has issued a high alert to district magistrates to be prepared and monitor embankments closely, with officials' leave being cancelled. The water discharge through the Birpur barrage is expected to reach 6.81 lakh cusecs by Saturday night, close to the highest discharge recorded in the past. Similarly, the Valmikinagar barrage may reach a two-decade high discharge level. Fourteen districts have been put on high alert, including Supaul, Saharsa, Khagaria, Bhagalpur, and Katihar due to the rising river levels.Champaran, East Champaran, Gopalganj, Sitamarhi, Sheohar, Muzaffarpur, Saran, Vaishali, and Samastipur are experiencing flooding caused by the overflowing Gandak river. In addition, the Bagmati river is also threatening to cause serious flooding in Sitamarhi, Sheohar, and Muzaffarpur districts, among others.
