There was a river called Kalong flowing through Nagaon, Morigaon and Kamrup district of Assam, India. Kalong starts its journey from mighty Brahmaputra and flowing through valleys (of three districts) and again meet Brhmaputra along with another river Kapili in the same spot. In post independent India, planners were becoming blind with power and half learned knowledge of technology, tamed the river at its source, in the name of flood control and irrigation. This exercise stopped the flow of water through the river channel and water for irrigation is becoming a distant dream for the farmer. But the hydrological   and seismological situation of the region indicates Kalong will revive one day and it will create its own path again; but nobody knows what will happened to villages and towns developed on its old path.
