History
According to historical as well as geographical records, the Dihing once flowed through entire
Upper Assam and met the
Brahmaputra at Mahuramukh in
Bokakhat. At that time the rivers Disang,
Dikhou, Disai,
Dhansiri were all tributaries to the Dihing. The river later dried out during the 17th century (as mentioned in
Buranjis) and changed course to join the Brahmaputra at Dihingmukh.
Even before that, the river met the Brahmaputra near the confluence of
Subansiri river. At that time the Dikhou river had an independent route and flowed as
Kolong and joined the Brahmaputra at Kajalimukh in
Nagaon district.
