More than 10,000 people of 23 villages in the char areas of Teesta and Dharala rivers in Lalmonirhat district have been trapped in flood water following onrush of water from upstream hilly areas.
The trans-boundary Teesta river was flowing 8 cm above the danger level at Doyani point on Tuesday morning.
The officials of Bangladesh Water Development Board (BWDB) said the situation became worsened as India had opened the sluice-gates of the Gazaldoba barrage.
“Now, water is entering Bangladesh with a heavy pace,” they added.
Meanwhile, 44 gates of the Teesta Barrage have been opened to control the flow of water.
Besides, the temporary dams in Dhurni village of Hatibandha upazila are also now at risk, they said.
The water level started to rise from Monday morning and the condition is worsening gradually, according to locals, UNB reported.
BWDB Executive Engineer Rafiqul Alam Chowdhury of Teesta Barrage Irrigation Project said the situation will be worsened more if the onrush of water from upstream hilly areas continues.
