Idukki: The water level in the Mullaperiyar Dam has been rising steadily over the last few days, raising concerns in Kerala. While the maximum water level allowed is 142 feet, the reservoir of the dam had water up to the 135.10-ft mark on Thursday.

According to the order of the Central Water Commission, Tamil Nadu, which is in charge of the dam, can maintain a water level of 142 ft two times a year and is likely to raise the shutters only if the level touches this maximum mark.

As per the protocol in place to release water from the dam, Tamil Nadu will issue the first alert to Kerala when the level reaches 136 ft. Subsequently, the second alert would be given at 138 ft, the first warning at 140 ft and second warning at 141 ft. When the level reaches 142 ft, shutters of the dam would be lifted.

At the same time, Tamil Nadu has not agreed to Kerala’s request to release water from the dam in a controlled manner after the level crosses the 136-ft mark.

Meanwhile, the Kerala State Electricity Board (KSEB) said that it would continue to release water at 100 cubic metre-per second (cumecs) on Friday also. In case the rain subsides, the amount would be reduced or the spillway closed, it added.

At the same time, the release from Edamalayar Dam has been reduced from 123 cumecs to 80, while from Pamba Dam it is now 10 cumecs instead of the earlier 14. From Kakki Dam, the amount continues at 95 cumecs.

“Water is currently being released from 12 of the 18 dams under the KSEB,” said Board Chairman B Ashok.
