Heavy rainfall and upstream mountain runoff have caused the Teesta River to swell dangerously in Nilphamari’s Dimla upazila. At the Dalia point, the river’s water level rose 15 centimeters above the danger mark on Monday night, flooding vast areas of Dimla and Jaldhaka upazilas. Around 5,000 families have become waterlogged as floodwaters entered homes, forcing residents to endure sleepless nights and threatening livestock and crops. The Water Development Board (WDB) opened all 44 gates of the Teesta Barrage to manage the situation.

According to the WDB, the water level, which was below the danger mark at 3 p.m., began rising rapidly from 6 p.m. and reached 52.30 meters by 10 p.m., surpassing the danger level of 52.15 meters. Low-lying areas in ten unions, including Purba Chhatnai, Khogakhharibari, Tepakhharibari, Khalisha Chapani, Golmunda, and Dauyabari, have been inundated. The Dalia WDB executive engineer stated that heavy rainfall in India’s upstream regions is driving the rise in water levels. Local authorities and the WDB are monitoring the situation and warning residents in vulnerable areas to move to safer locations.
