A flood-protection embankment along the Bhairab River at Bhadrapara in the Sadar upazila was washed away by the tidal surges on Friday, stranding 300 families in three villages.
A vast portion of Bhadrapara, Boitpur, and Bemorta villages have been flooded with fish of 20-25 enclosures washed away.
The residents of the three villages demanded immediate steps to repair the collapsed embankment.
Mashiur Rahman Badsha, an owner of a fish enclosure at Bhadrapara village, said when the flood protection embankment collapsed in the afternoon water entered his fish enclosure and washed away all fish, incurring a loss of Tk 10 lakh.
Alamgir Hossain, a resident of the village said, "We have been suffering amid the knee-deep water in the houses. Even we could not cook properly as the yards of the houses were flooded."
Md Masum Billah, the executive engineer of the local Water Development Board, said Dartana and Bhairab rivers were flowing 12 cm above their danger marks while the water level of different canals and water bodies have also risen.
"We were informed that low-lying areas of different villages have been flooded and steps will be taken to build a ring dam after the recession of the tidal water.
