A dam along the coastal areas of the district is on the verge of collapse, with incessant showers having caused all major rivers across the district to swell.
With water levels of all the major rivers in Ashashuni and Shyamnagar upazilas of the district rising by the hour, several low-lying areas have already been inundated. Many fish enclosures have been washed away in these two upazilas, officials said.
Zulfikar Ali Ripon, officer-in-charge of Satkhira Weather Observatory Centre, attributed the showers to the depression in the Bay of Bengal.
The weather department has recorded 30mm of rainfall in the district in the past 24 hours, he said.
Abul Khayer, executive engineer of Satkhira Water Development Board, said that a 62-km span of the dam at 35 points of the coastal areas, out of 800km, is at risk of collapse, though repair work is under way.
