Tamil Nadu Public Works and Sports Development Minister Aadhav Arjuna, the TVK leader, on Sunday, 26 July mounted a sharp defence of the Vijay government's record on the Cauvery River dispute, accusing Dravida Munnetra Kazhagam (DMK) president and former Chief Minister M.K. Stalin of making misleading and factually incorrect allegations against the current administration over the Mekedatu dam issue. The minister's remarks mark a fresh escalation in the political battle over Tamil Nadu's water rights.
What the Government Has Done
Aadhav maintained that the state had pursued legal, administrative, and political channels to protect its rightful share of Cauvery waters. He highlighted that Chief Minister C. Joseph Vijay personally raised Tamil Nadu's objections with Prime Minister Narendra Modi during a meeting on 27 May, urging the Centre to ensure implementation of the Cauvery Water Disputes Tribunal's final award and the Supreme Court's verdict of 16 February 2018, while firmly opposing any clearance for the Mekedatu reservoir.
Following reports that Karnataka was preparing to perform a bhoomi pooja for the proposed reservoir, Chief Minister Vijay wrote again to the Prime Minister on 19 June, reiterating that the project could not receive clearance without the consent of all co-basin states — Tamil Nadu, Kerala, and Puducherry. The letter also requested the Centre to issue suitable directions to the Union Ministry of Jal Shakti and the Central Water Commission.
Legislative and Regulatory Pressure
The minister pointed out that the Tamil Nadu Legislative Assembly had unanimously passed a resolution opposing the Mekedatu project and forwarded it to the Prime Minister, seeking immediate intervention. The state has also consistently pressed its case before the Cauvery Water Management Authority and the Cauvery Water Regulation Committee, demanding timely release of Tamil Nadu's allocated water share and objecting to Karnataka's unilateral actions.
Counter-Attack on DMK
Turning the criticism on the DMK, Aadhav alleged that the previous government had failed to effectively defend Tamil Nadu's interests following adverse developments in the Supreme Court. He claimed that legal shortcomings during the earlier regime had made both the Cauvery and Mekedatu disputes harder to resolve — a charge the DMK has not yet formally responded to.
What the Government Says Next
Describing the Cauvery issue as one concerning Tamil Nadu's fundamental rights rather than political rivalry, Aadhav said the Vijay administration would continue to pursue every constitutional and legal avenue to protect the state's water rights. He added that the government remained open to constructive criticism, provided it was directed at safeguarding Tamil Nadu's long-term interests. The dispute is likely to intensify as Karnataka's proposed project timeline draws closer to ground-level activity.
Point of View
Which is the more uncomfortable question the minister did not address. The Cauvery dispute has outlasted multiple governments precisely because it sits at the intersection of federal water law, inter-state politics, and electoral arithmetic in both Tamil Nadu and Karnataka. Framing it as a matter of 'fundamental rights' rather than political rivalry is rhetorically effective, but the structural impasse remains unchanged.
