Kerala government blamed Tamil Nadu for unprecedented floods saying it was caused by sudden release of water from Mullaperiyar dam. The floods claimed more than 400 lives and damaged property worth thousands of crores of rupees, .

Kerala government knocks door of Supreme court on this and filed case against Tamil Nadu in apex court. Kerala government argued they have requested to gradually release water from Mullaperiyar Dam but Tamil Nadu never gave positive response on this and suddenly released water. This led to more water release from Idukki reservoir resulted in flood,the affidavit filed in Supreme Court said.

Kerala Chief Secretary said the state was managing the spate of water by controlling spill and letting a major portion of the flood waters to escape to the sea by implementing a strict operational control over the spill of the two largest reservoir systems of Idukki and Idamalayar in synchronization with eight small other reservoir systems in the Periyar basin. But the sudden releases from the Mullaperiyar Dam, forced us to release more water from the Idukki reservoir, which is one of the causes of this deluge.
