Around 1.25 lakh people were stranded as Brahmaputra and Ghaghat rivers continued to swell, worsening the overall flood situation of Gaibandha on Tuesday.
At least 26 unions in Sundarganj, Phulchhari, Saghata and Sadar upazilas were inundated due to incessant rain and onrush of water from the upstream.
People hit by the flood are suffering from scarcity of food, water and sanitation. Many people have been forced to take shelter on flood control embankments.
Road communication was disrupted as many important parts of the roads have gone under water, locals said.
Executive Engineer Mokhlesur Rahman of Water Development Board said the water of Brahmaputra and Ghaghat rivers were flowing 99cm and 71cm above the danger level respectively.
The water will continue to rise for next two days, although the flood control embankment is currently functional but emergency protective work is underway at important points, he said.
Deputy Commissioner Abdul Matin said Tk 4 lakh, 100 metric tonnes of rice, 1,800 packets of dry foods and Tk 2 lakh for child food have been allocated for the flood hit areas of four upazilas.
