PATNA: Bihar districts bordering Nepal between the Mahananda and the Bagmati river basins may see water levels rise as heavy rain has been predicted on the Nepal side.
“Heavy rains have been predicted over the next couple of days in the Nepal area between the Mahananda and Bagmati river basins. The rainfall received in Nepal will be in the range of 60 mm to 150 mm,” a state water resources department official said.
“This, however, does not necessarily mean that Bihar districts bordering Nepal will witness flood-like situations.
The increase in volume of water through the rivers will not be menacing, because most of the rivers originating in Nepal and passing through these districts are empty of water,” he said.
“They will hold whatever water flows into them from Nepal. Light to moderate rainfalls received in the Bihar plains by themselves do not cause any problems,” he added.
The districts which might see a rise in the water level of the rivers passing through them are Kishanganj, Araria, Supaul, Madhubani, Muzaffarpur, Sheohar and Sitamarhi. Over and above the major rivers Mahananda, Kosi and Bagmati that pass through these districts are the minor ones like Kamla Balan. There are also quite a few small rivers that have the nature of suddenly acquiring menacing form, like in Araria and Kishanganj districts.

The situation currently is manageable as water discharge through the Valmiki Nagar barrage across Gandak was 85,500 cusecs and through the Birpur barrage across Kosi 1.30 lakh cusecs at 4 pm on Thursday, but more rains received in their catchment areas in Nepal would change the situation.
The water levels in Gandak and Kosi in Bihar have been showing a rising trend due to the changing water intake of their tributaries in Nepal, but most rivers have been flowing below the danger level. As to river Kosi itself, water discharge at Barahkshetra in Nepal, 60 km north of the Birpur barrage, was 94,775 cusecs with increasing trend.
