The first wave of floods of the year has hit the State with 20 villages in Dhemaji district being submerged by waters from Arunachal Pradesh. 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. Flood waters from the Jiyodhal river have already washed away a bridge on NH-52 snapping Dhemaji-Lakhimpur road connectivity. The district administration has sounded a red alert in the entire district. To maintain road connectivity between Dhemaji and Lakhimpur, an alternative arrangement has been made with the Dhemaji-Butikur-Ghilamara-Gogamukh route from 12 noon today. Dhemaji DC Dibakar Mishra has instructed the State administration to ensure supply of essential commodities.
