The first wave of floods that hit Assam about a week ago continues to wreak havoc, affecting over 30,000 people in seven districts of the state till Tuesday.
The official flood report said Lakhimpur, Darrang, Hailakandi, Sonitpur, Dhemaji, Udalguri and Nagaon districts had been affected.
The flood water have also submerged 1,096 hectares of crop area in the affected districts, the report said.
The State Disaster Management Authority (SDMA) said the water levels in major rivers such as Brahmaputra and Burhidehing were rising at some points in upper Assam and flowing over the danger level.
Last week, the rising water level had breached a dyke on Pisola river in Lakhimpur district and submerged a vast area.
Similarly, the surging water of three rivers -- Suklai, Bornodi and Naobondha -- have inundated large swathe of agricultural lands and human habitations in lower Assam.
