Eight river monitoring stations in northeastern Bangladesh reported water level rising above their danger marks by Monday morning, up from six a day earlier, as moderate to heavy rainfall continued across the haor basin and upstream in India’s Meghalaya and Assam.

The Bangladesh Water Development Board said water levels had climbed further in most rivers in the region over the preceding 24 hours, with fresh pressure emerging at several points. At Jagannathpur in Sunamganj district, the Naljur river swelled another 11 centimetres and now flows 40 centimetres above its danger threshold.

In Netrokona, the Dhanu-Baulai rose 9 centimetres to pass 8 centimetres above the danger level. The Someshwari, though falling 14 centimetres at Kalmakanda, still ran 50 centimetres above the mark. The Bhugai-Kangsa dropped 22 centimetres but held 67 centimetres above the limit, while the Mogra gained 5 centimetres at Netrokona town to reach 79 centimetres above and remained unchanged at 27 centimetres above at Atpara.

The Kalni at Ajmiriganj in Habiganj rose 15 centimetres to stand 10 centimetres above the danger level, and the Sutang at the Sutang rail bridge climbed 23 centimetres to 83 centimetres above the mark.

Water levels in the haor wetlands of Sunamganj were rising extremely slowly, the board said, at an average rate of zero to one centimetre per hour.

Heavy rain persisted across the basin on Monday. Jaria Jhanjail in Netrokona and Habiganj town each recorded 74 millimetres of rain, while Chandpur-Bagan received 61 millimetres. Across the border, Cherrapunji recorded 14 millimetres, enough to sustain elevated upstream flows into Bangladesh’s northeastern river system.
