A day after a devastating flash flood in Nepal claimed hundreds of lives, water levels in Bihar's Gandak, Ganga, and other tributary rivers began to subside significantly on August 27, easing the immediate flood threat. At the Valmikinagar barrage in West Champaran, water flow peaked at around 1.5 lakh cusecs, with waves reaching nearly three metres high during the afternoon, before conditions started to improve.The Gandak River, known as the Narayani River in Nepal, carried debris and cattle carcasses from the flood-hit areas across the border.
Authorities closely monitored the situation around Valmikinagar and the Indo-Nepal border to assess the impact of the sudden rise and fall in river levels. Bihar Chief Minister Samrat Choudhary, accompanied by senior government officials, conducted an aerial survey of the barrage and surrounding areas to review the flood situation and oversee preparedness and relief measures. Although receding water levels provided significant relief, officials continue to monitor the river system and vulnerable riverbanks to respond quickly to any renewed rise or residual impacts from the Nepal floods.
