Replying to CPI's call attention motion in this regard in the state Assembly, Public Works Minister K V Ramalingam said Chief Minister J Jayalalithaa had directed for talks between authorities of the two states.
"If it fails, we will approach the Supreme Court," he said.
Earlier, in a written reply, he said the Cauvery Tribunal had allocated 2.87 tmcft of water for Kerala's proposed dam on Siruvani at Attappadi but Tamil Nadu government had sought the project details and also informed Kerala in February that it could not go ahead with the project till the final award of the Cauvery Disputes Tribunal came into force.
Following reports of check dams on Bhavani in Palghat district which subsequently affected Coimbatore and Erode districts, Tamil Nadu government had asked Kerala on March 15 to remove the "blockades created by farmers" there, Ramalingam said.
While the final award of the Cauvery tribunal has been notified in the Central gazette, Kerala cannot immediately implement the project as it has to get the approval of Cauvery Management Baord and Cauvery Water Regulation Committee, both yet to be formed, besides that of CWC, he said.
