Year after year, most of the North Bihar districts, from East Champaran and Gopalganj to Araria and Supaul, have to brace for the floods with or without excessive rainfall during the monsoon. More often than not, floods in Bihar are caused by heavy rains in the catchment area of the adjoining Nepal districts, but the state can hardly do anything about it. There has been a long-standing demand to build a dam along the Indo-Nepal border so as to check the flow of rain water into Bihar from the Himalayan nation, but nothing has happened despite protracted talks between the mandarins of both countries. In 2008, a breach in the eastern embankment at Kusaha in Nepal had caused devastation in several districts of Bihar, leaving more than 500 people dead, 3,600 people missing and more than 30 lakh homeless.
