The overall flood situation in Assam showed first signs of improvement with cessation of heavy rain that lashed parts of the state last week.
"There is a slight improvement of the situation with the respite from downpour for continuous four days and the rivers, including Brahmaputra showed a receding trend," official sources said.
The death toll stood at 35 and more than 12 lakh people were affected in 23 of the 27 districts due to the rising water of Brahmaputra and its tributaries in the first wave of flood this year, they said.
While the Brahmaputra was flowing above the danger mark in five of the six gauge stations including Neamatighat, Tezpur and Guwahati, it maintained a rising trend in lower Assam's Goalpara and Dhubri districts.
Three major tributaries of Brahmaputra - Buridihing, Dhansiri, and Kopili were flowing above the danger mark, but most of the other tributaries recorded a receding trend, the sources said.
Nearly two lakh people still remain affected in Majuli, Asia's largest river island in upper Assam's Jorhat district, while several animals including about 10 deers lost their lives in flood water in Kaziranga national park.
