The overall flood situation in Sylhet district has not improved, despite eight days having passed since flash floods hit this region.
The Surma and Kushiarar rivers continue to flow above the danger level due to the onrush of hilly waters from India as 2,200 mm of rainfall has been recorded in Cherrapunji of Meghalaya state in the last eight days.
The dyke, a long wall built to prevent flooding, collapsed at the Barak river along the border with India, due to the onrush of hilly waters in the small hours of Friday, inundating several areas of Zakiganj upazila, including Fillakandi, Amalshid, Barthakuri, Khasirchak, Khairchak, Baroghatta and Sonasar.
At the same time, the road communication between Zakiganj and Sadar upazilas was snapped due to flooding, said acting upazila nirbahi officer (UNO) of Zakiganj, Pallab Hom Das.
