Tamil Nadu, Kerala top officials discuss water disputes

The Tamil Nadu and Kerala governments have decided to move ahead in implementing the Pandiyar-Punnampuzha scheme that envisages utilisation of the west flowing waters of Pandiyar and Punnampuzha rivers that drains into the Arabian sea. 

During the six hour-long meeting in Thiruvananthapuram in Kerala, both the governments represented by senior officers of irrigation and electricity departments discussed the inter-state water disputes, including Parambikulam-Aliyar Project that benefits the western districts.

Tamil Nadu stated in the Supreme Court recently that the flood havoc that occurred in Kerala in 2018 and 2019 was not caused by the water that flowed from Mullaiperiyar dam. 

In an affidavit submitted in the Supreme Court, Tamil Nadu pointed out that more quantity of water flowed to Periyar from the dams in Kerala than the water from Mullaperiyar dam.

Tamil Nadu also stated in the affidavit that 21 small earthquakes were experienced in the Mullaperiyar dam region during the period between January and May this year. TN said this in the affidavit submitted in response to the petition filed by Russell Joy demanding to reduce water level in Mullaperiyar dam to 130 feet from July to September when monsoon is stronger.

The Mullaiperiyar dam, operated by Tamil Nadu, is exceptionally vulnerable because of its large catchment area and limited storage capacity, the state government informed the Kerala High Court recently. 
The state made the submission following a directive from the court to furnish the details of dam management.The Mullaiperiyar reservoir has a catchment area of 624 sq km and effective storage capacity of 7.666 TMC.
