At least 30,000 people in Lalmonirhat got trapped due to severe flooding from heavy downpour and onrush of water from upstream hilly areas in India.
Flowing of the Teesta and Dharala rivers above the danger level on Saturday made the situation more complicated.
Bangladesh Water Development Board executive engineer Mostafizur Rahman at Dalia said the trans-boundary Teesta river was flowing at least five centimetres above the danger level at the Dalia point while Dharala seven centimetres above the danger level at Kulaghat point on Saturday morning flooding vast areas of several upazilas, namely Hatibandha, Kaliganj and Aditmari, of the district, which experienced severe flooding a month ago.
Several thousand people in different unions of Hatibandha upazila, Kakina and Votemari union of Kaliganj upazila, Mohishkhocha of Aditmari upazila, Khuniagas, Mogholhat, Kulaghat and Rajpur areas of Sadar upazila are now facing flood.
If the flow of onrush of water from the hilly areas continued, some 100 villages of Lalmonirhat district would go under water, the local administration said.
Meanwhile, the officials at local BWDB office warned the inhabitants of the low-lying areas of Teesta and Dharala to remain alert about the latest flood situation.
Md Anamul Kobir, upazila nirbahi officer, Hatibanda, said they were monitoring the situation and had asked the higher authorities for relief for the affected people.
The WDB sources said that onrush of hilly waters raised concern as India opened 54 gates of Gajaldoba Barrage and issued alert in the adjacent areas.
The Teesta Barrage authority also opened 44 gates to tackle the pressure of gushing waters from upstream.
The flood situation in the district worsened further on Saturday as fresh areas of 30 villages in five upazilas went under water, leaving 30,000 people marooned, he added.
Meanwhile, embankment at Shiberkuti point under Kulaghat union in sadar upazila was eroded due to the pressure of gushing water which caused fear of further erosion.
Idris Ali, chairman of Kulaghat union, said, ‘Now the rivers Dharla and Ratnai are separated by only one meter area. If the erosion by both of the rivers started together, at least three lakh people of the district will be left marooned.’
Sub-divisional engineer of Lalmonirhat Water Development Board, Abdullah Al Mamun said, ‘We started dumping sand bags in the affected areas to prevent further erosion.’
Local people, mostly farmers, said they were just struggling to cope with the flood that caused huge damage to their standing crops, livestock and homesteads in August.
The flood water receded in early September, they added.
