The affected villages are Dihing, Bhokot, Bhokotkoibotta, No.1 Bokulbari, Morolusuk, Kalitagaon, Nagaon, Station Colony, Milangaon, among others. Continuous rainfall in Arunachal Pradesh last week resulted in overflowing of the Jiyadhol, Gai and the Kumotia rivers, waters from which accumulated in the Somarjan area of Dhemaji district. It may be mentioned here that floods have been a regular feature in the Somarjan area for the last ten years.
