The decades-old Mullaperiyar dam dispute has resurfaced as a live flashpoint in Kerala-Tamil Nadu relations after the Tamil Nadu government used its Budget to announce it would pursue raising the dam's water storage level — a move Kerala has called unfortunate and firmly rejected, even as it called for fresh inter-state dialogue, including a possible meeting between the two Chief Ministers.

Kerala's Position: New Dam, No Compromise

Kerala Water Resources Minister Mons Joseph said the state would initiate discussions with Tamil Nadu and was open to exploring a Chief Minister-level meeting to address the impasse. However, he made clear that Kerala's core stance remains unchanged: the Mullaperiyar dam has not undergone the comprehensive safety evaluations the state has consistently demanded, and the construction of a new dam is non-negotiable.

The minister noted that the current water storage level of 142 feet is maintained strictly under directions from the Supreme Court of India, and neither state has the unilateral authority to alter it. Kerala's position, he said, is that any modification to the storage level must be considered by the Supreme Court after hearing submissions from both sides.

What Tamil Nadu's Budget Said

The Tamil Nadu Budget stated that the government would pursue raising the Mullaperiyar water level in accordance with existing agreements, tribunal awards, and judicial directions. It also pledged to safeguard Tamil Nadu's water rights, accelerate the Anamalayar and Nallur dam projects, oppose proposals such as the Mekedatu project that could affect Tamil Nadu's interests, and fast-track the Godavari-Cauvery river-linking project.

A Political Opportunity That Went Unused

The renewed friction comes against a backdrop of growing disappointment in Kerala over the lack of any political breakthrough during the 2021-26 tenure of the previous Left government. There had been considerable expectations that the personal rapport between then Kerala Chief Minister Pinarayi Vijayan and Tamil Nadu Chief Minister M.K. Stalin — both prominent figures in the INDIA bloc — would help create conditions for progress on one of South India's most sensitive inter-state disputes.

Despite multiple meetings between the two leaders on a range of issues, the Mullaperiyar question reportedly remained largely unaddressed. The window of political goodwill, observers note, was not used to advance a resolution.

What Happens Next

The latest exchange suggests the Mullaperiyar issue, which had remained relatively dormant in recent years, could once again emerge as a major point of contention between the two states. Whether the proposed Chief Minister-level dialogue materialises — and whether it can bridge positions that have remained entrenched for years — will be closely watched across both states and in the Supreme Court, which retains oversight of the dam's operational parameters.
