Gandak River surge triggers flood alerts in Bihar following heavy rainfall in Nepal

Gandak River flood Valmikinagar Barrage Bihar flood alert Nepal rainfall river discharge

Heavy rainfall in Nepal has caused a significant surge in the Gandak River, leading to flood alerts across several districts in Bihar, India. At the Valmikinagar Barrage, all 36 gates have been opened to manage the increasing water volume. As of the morning of September 27, the discharge rate was recorded at 416,000 cusecs, with projections suggesting it could reach 450,000 to 500,000 cusecs by later in the day.

In response to the rising water levels, authorities have issued alerts for 13 districts within the Gandak basin, including West Champaran, East Champaran, Gopalganj, and Saran. In West Champaran, emergency measures are underway, including the evacuation of residents from low-lying areas to shelters in Bherihari.

The Bihar Water Resources Department has placed regional officials on 24-hour alert and is closely monitoring embankments. Despite the high discharge, officials noted that the risk of widespread flooding is currently mitigated by the low water levels in the Ganga River, which allows for efficient drainage of the Gandak's waters.

Separately, in Chhatarpur, India, heavy rains have forced the opening of all gates at the Singhpur Dam on the Urmila River, raising concerns for residents in nearby low-lying areas.
