Central Water Commission (CWC) is the only agency doing flood forecasting in India. CWC’s Flood Forecasting (FF) is available on its website[I]. In this article we have given an overview of CWC’s flood forecasting and monitoring sites in East India. It includes state wise list of CWC’s Level Forecast, Inflow Forecast and level monitoring sites in East India. Similar report has been published for North India[II] and North East India[III] and we hope to publish reports covering other regions of India soon. East India includes five states: Bihar, Jharkhand, Chhatisgarh, Odisha and W Bengal.

Floods in East Champaran started following the heavy rainfall in the last week of July 1987. There was a sudden rise in the flood levels of the tributaries of the Burhi Gandak (Sikrahana) like the Sarisawa, the Tilawe, the Gaadh, and the Bangari leading to submergence of lower areas of Raxaul town where flood water of depth up to two to two and half feet was spread all over. This initial flood had also affected 25 Panchayats and 125 villages in the blocks of Raxaul and Ramgarhawa. The rains that set in on the 26th July, 1987 continued unabated and by the time of the beginning of August all the major rivers –the Gandak, the Burhi Gandak and the Bagmati were in spate. Road communication of Motihari, the district HQ of East Champaran, was disrupted fully in this very first spell of floods. There was three feet deep water passing over NH-28 near Chhapwa. The road to Bettiah and Areraj was too badly damaged to afford vehicular traffic to pass through. Road from Pipra Kothi to Siwan was already damaged much before the rains and its condition deteriorated further after rains. All the three rivers were flowing above danger mark on the 2nd August, 1987 and a vast cultivated area along with hundreds of villages came under a sheet of flood water of these rivers. The train service between Sugauli and Darbhanga was suspended because of flood water on the railway track. Continue reading “Bihar Floods in 1987 – II – East Champaran”

In the preceding year of 1986 the flood was severe in many parts of Bihar but as the rainy season drew to close, the last October rains failed and a vast area of the State came under the grip of drought. Surprisingly, the districts cited for perennial floods like Saharsa, Purnea and Khagaria in the State were also hit by the drought. The year 1987, however, was worst for floods in Bihar (in addition to UP and W Bengal) while the rest of the country was facing one of the most severe droughts in the century. Many parts of the country were facing famine like situation while all the rain bearing clouds had moved toward Bihar. Traditionally, two days of continuous rains or a clear sky of the same duration during the rainy season signals floods or drought in the State and makes farmers apprehensive of the days to come.
