 The geographical condition of the region was very different from today in those times.At that time, the Dihing river flowed south of present-day Moranhat and Sepon region as the Disoi, had the rivers Disang and Dikhou as its tributaries, ultimately joining the Brahmaputra in Mahuramukh(Bokakhat) and Lakhou(Kaliabor).At a later period (probably late 16th century), this stream of the Dihing dried out and the Dihing took another course to the north.
