Since the beginning of human civilization, rivers have been an important part of human life. North Bihar has 7 major rivers and several tributaries to them. North Bihar districts are vulnerable to at least five major flood-causing rivers during monsoon – Mahananda River, Koshi River, Bagmati River , Burhi Gandak River and Gandak – which originate in Nepal.[20] All these rivers receive water from the Himalaya. This is the reason that these rivers never have a shortage of water. Every year, any of these rivers had been bringing valuable floods for the people of North Bihar. Flood waters used to enter the agricultural land, leave their quite fertile silt and recede to the river. This pattern of humane flood was a boon for North Bihar. This made her land extremely fertile. But, natural floods are no more in North Bihar.

Soon after independence, the Congress Government of Bihar made several attempts to domesticate these rivers. High barriers or Bandhs were made on their both banks. This resulted in inhumane and destructive floods. Bandhs caused deposition of silts in the bottom of rivers, because of which, depth of rivers decreased, and so their water holding capacity also decreased. This is the reason these rivers bring more frequent floods now. With flood water, sand comes in force and gets deposited on the land. This way the land of the region in turning barren. Floods, which were once a boon for North Bihar, has now turned to be a curse for it.

The 2008 Kosi flood was one of the most disastrous floods in the history of North Bihar, an impoverished and densely populated region in India. A breach in the Kosi embankment near the Indo-Nepal border (at Kusha in Nepal) occurred on 18 August 2008. The river changed course and inundated areas which hadn't experienced floods in many decades.[22] The flood affected over 2.3 million people in North Bihar.[23]

The flood killed 250 people and forced nearly 3 million people from their homes in North Bihar.[24] More than 300,000 houses were destroyed and at least 340,000 hectares (840,000 acres) of crops were damaged.[24] Villagers in North Bihar ate raw rice and flour mixed with polluted water. Hunger and disease were widespread. The Supaul district was the worst-hit; surging waters swamped 1,000 square kilometres (247,000 acres) of farmlands, destroying crops.[25]
