Record Discharge at Barrages on Kosi and Gandak Rivers Heightens Flooding Risk in 14 Bihar Districts
In Patna, Madhubani, and Motihari, the significant increase in water discharge from the Birpur barrage on the Kosi river and the Valmikinagar barrage on the Gandak river has caused concern about potential flooding in low-lying areas across 14 districts. Heavy rainfall in north Bihar's river catchment areas in Nepal and within their own basins has heightened the risk of flooding. The water discharge through the Birpur barrage reached 5.31 lakh cusecs by 2pm, up from 4.80 lakh cusecs earlier in the day. Similarly, the Valmikinagar barrage's discharge rose from 3.84 lakh cusecs to 4.49 lakh cusecs during the same period. The imminent flood threat is most severe for Bhagalpur and Katihar districts, as the Kosi river merges with the Ganga river in Kursela and the Gandak river is near Patna. Precautionary measures, such as public announcements urging residents between the Kosi embankments to relocate to higher ground, have been initiated in Supaul. The state water resources department has alerted district magistrates to prepare for the increasing water levels and to closely monitor embankments. Official leaves have been canceled, and it is anticipated that the water discharge through the Birpur barrage will reach 6.81 lakh cusecs by Saturday night, nearing the all-time high of 7.25 lakh cusecs. Similarly, the Valmikinagar barrage's discharge is expected to reach a two-decade high. The 14 districts on high alert include Supaul, Saharsa, Khagaria, Bhagalpur, and Katihar due to the rising water levels in the Kosi river.Champaran, East Champaran, Gopalganj, Sitamarhi, Sheohar, Muzaffarpur, Saran, Vaishali, and Samastipur are being affected by the flooding of the Gandak river. In addition, the Bagmati river is also causing significant flood risks to the districts of Sitamarhi, Sheohar, and Muzaffarpur, among others.
