The Jamuna River in Sirajganj is swelling rapidly due to the onrush of water from the upstream and heavy rainfall. According to Nazmul Hossain, sub-divisional engineer of the Sirajganj Water Development Board (WDB), the water level began to climb on Sunday. Nazmul said that the Jamuna River at the Kazipur point suddenly rose by 75cm at 6am on Tuesday, flowing 194cm below the danger level. At the hard point area, the water level rose by 64cm, flowing 170cm below the safety level. Mokhlesur Rahman, executive engineer of the Sirajganj WDB, said despite the unusual rate of increase in the Jamuna's water, there is no need to panic.
