The flood situation in the eastern, southern and northern regions of the country worsened on Saturday as major rivers there were flowing above the danger-line.
The Teesta River was flowing 27cm above the danger level at Dalia point in Nilphamari district around 9am on Saturday, flooding the char and low-lying areas under Dimla and Jaldhaka upazilas.
Meanwhile, 15 unions under Nilphamari Sadar upazila have become waterlogged as an effect of the non-stop downpour.
Bangladesh Water Development Board’s (BWDB) Dimla Division Executive Engineer Mostafizur Rahman said they had already asked residents of the at risk areas to move to safer areas.
Nilphamari Deputy Commissioner Khaled Rahim said the flood situation had worsened around the Teesta’s downstream areas after the sluice gates of the Gajoldoba Barrage in India were opened to counterbalance the rise in the river’s water level.
The BWDB officials have also opened all the 44 sluice gates of the Dalia Barrage in Bangladesh to control the water flow in the river.
The swelling of the Teesta has also led to the inundation of its left bank areas in Lalmonirhat district.
The Dharla River was also flowing 32cm above the danger line in Lalmonirhat in the morning on Saturday.
About 150,000 people have reportedly been marooned by the flood in all the five upazilas of the district.

Sudden increase in the water level of the Karotoa, Mahananda, Dahuk and Bhersa rivers on Friday night prompted hundreds of people in Sadar, Tentulia and Boda upazilas of Panchagarh district to move to the shelter centres.
Panchagarh BWDB Executive Engineer Md Mizanur Rahman said the Karotoa was flowing very close to the danger level around 8am on Saturday following 290mm rainfall over the last 24 hours.
