Tamil Nadu warned Kerala when the water level rose in the Mullaperiyar dam during the critical days of the devastating floods, the State said in a counter-affidavit filed before the Supreme Court on Friday.
The Tamil Nadu government denied allegations it waited too long until the water storage level crossed the permitted mark of 142 feet.
Kerala had alleged in its affidavit on Thursday that it was uncertain about the water level in the Mullaperiyar dam even as it was “frantically” evacuating people from downstream areas of the dam.
It said there were no “positive assurances” from Tamil Nadu to its request for gradual release of water at least at 139 feet during the torrential rains.
Tamil Nadu submitted that it had “duly informed Kerala since the water level in the dam reached +136 ft. Thereafter, when the water level reached +138 ft, +140 ft, +141 ft and +142 ft, suitable warnings were issued and the quantum of discharge was also intimated. Thus the State took all the required measures before water was released from the dam.”
Periodical warnings were issued since the water level reached 136 ft for every two feet rise, and from 140 onward for every one foot rise. Intimation was given to the Kerala government well in advance regarding the release of water from the spillway of the dam, the counter-affidavit said.
“The allegation that action was taken by the Respondent State (Tamil Nadu) only after the water level in the dam crossed the permitted storage of +142 ft, is denied,” Tamil Nadu said in its affidavit.
