The Water Development Board (WDB) opened all the 44 gates of Teesta Barrage on Friday to rein in the high water pressure, with the river flowing 35cm above the danger level.
Around 11am on Friday, water flow in the barrage was recorded at 52.95 cm, said WDB officials.
"Due to heavy rains, most of the gates of Gajal Doba barrage on the Indian side were opened, which increased the water level of the Teesta and adjoining small rivers," said Executive Engineer Mizanur Rahman.
But the official said the water level may decrease by afternoon.
