Assam's flood-prone districts of Lakhimpur and Dhemaji was on Sunday hit by the second flood of the season following heavy rainfall in the catchment areas, official sources said.
The water level of Brahmaputra's tributaries Ranganadi and Singora was rising alarmingly with fresh areas being inundated affecting 30 villages under Lakhimpur and Naoboicha Revenue Circles.
The North Eastern Electricity Power Corporation released 30 cusecs of water and opened its sluice gates at the Ranganadi Hydel Power Project following technical snag in one of its power grid yesterday, the sources said.
This also led to fresh flooding in the two districts with the causeway of NH-52 near Ranganadi Bridge submerged and road communication disrupted.
The state government has directed the district administration to provide immediate relief and rehabilitation to the affected people, the sources said.
Several districts of Upper Assam was hit by the first wave of floods since the last week of March.
