More than 10,000 people of 23 villages in the char areas of the River Teesta and Dharala have been marooned following onrush of water from upstream hilly areas.
The trans-boundary River Teesta was flowing 8 cm above the danger level at Doyani point on Tuesday morning.
Bangladesh Water Development Board officials said that the situation became worse as India opened the sluice-gates of Gazaldoba barrage. As a result, water was entering Bangladesh with a heavy pace, they said.
Besides, the temporary dams at village Dhurni of Hatibandha upazila were also at risk, they said.
Local people said that the water level started to rise from Monday morning and the condition was deteriorating gradually.
BWDB’s Teesta Barrage Irrigation Project executive engineer Rafiqul Alam Chowdhury said that the situation would deteriorate if the onrush of water from upstream hilly areas continued.
Meanwhile, 44 gates of the Teesta Barrage have been opened to control the flow of water.
