Kosi, known as the river of sorrow of Bihar, also passes through Bhagalpur. This river is wreaking havoc this year as well. Kosi river, passing through Navgachiya subdivision of the district, has engulfed hundreds of houses and hundreds of acres of land in many villages. A video of this is also coming out, in which a house collapsed in the flood water. The villagers are also angry with the public representatives and the administration.
