The affected upazilas are Durgapur, Kalmakanda, Atpara, Madan, Mohongonj and Khaliajuri Netrakona, Water development Board (WDB) sources said.

Parts of Netrkona Sadar and Barhatta upazilas may go under water in the next 24 hours if the situation deteriorated, they said.

The water levels of Sumeshowary, Mogra, Kongsha and Dhanu rivers continued to rise yesterday. Dhanu river, flowing above the danger level, overflowed one kilometre of its bank in Nawtana area in Khaliajuri upazila. The rivers swelled due to onrush of water from hill across the border, the WDB sources said.

Sources said Birishiri, Kakoyirgora, Gaokandia, Bakoljura union in Durgapur upazila; Langura, Rangchati, Karnai, Pogla and Koilati union in Kalmakanda; Duaz, Sukari and Sunai union in Atpara; and vast areas of Madan, Mohongonj and Khaliajuri upazilas have gone under three to five feet water.

Most parts of the five kilometre Shibgonj-Ranikong road in Durgapur upazila, the only road link between the upazila headquarter and bordering villages, have been inundated.

Sources said, floodwaters inundated Kalmakanda, Mohaongonj and Khaliajuri upazila headquarters.

The flood waters damaged hundreds of acres of newly transplanted Aman fields.

Fishes in about 2000 ponds in Kalmakanda, Durgapur, Atpara, Madan, Mohongonj and Khaliajuri upazilas have been washed away, district fishery office sources said.

The road communication between the district headquarters and Durgapur upazila sadar is snapped as a portion of the road has been damaged near Janzail Bazar and Suknakuri in Durgapur upazila.

Road links from Netrakona town to Kalmakanda, Kendua and Madan upazila headquarters are snapped as those are under water.

About 20 kilomitres of the 60 kilometre road from Netrakona to Khaliajuri has gone under five to six feet water, snapping the link.
