Over a dozen villages under Barauli block of Gopalganj have so far faced partial submergence with their residents taking shelter in school buildings and canal embankments. The state has pressed 25 boats into relief and rescue operations under the National Disaster Response Force.
The state government had believed that there would be no rainfall here as well as in Nepal and,thus,no additional discharge of water in the river.
Last week,however,Nepal had to release two lakh cusecs water in Gandak that eventually broke through Saran embankment at Baterdah under Barauli,Gopalganj.
A senior water Resource department at the spot said: Gandak generally has a surge of water till September 22. The river can retreat only if there is no rain for the next few days,otherwise there could be a Kosi-like situation.
Principal secretary,disaster management department,Vyasji Mishra said that people of affected areas and those staying in changed river course have been moved to safer places along with with their belongings and cattle.
Mishra said relief materials and doctors too have sent to relief camps.
Locals,however,said that most of the affected people have not gone to government camps,put up at some distance from the partially submerged villages.
