Tamil actor and political leader Vijay has written a letter to Prime Minister Narendra Modi, urging his intervention in the ongoing Mekedatu dam dispute between Tamil Nadu and Karnataka. The letter, dated May 26, 2026, highlights the long-standing water sharing conflict over the Cauvery river and seeks the Prime Minister's attention to protect Tamil Nadu's interests.
What is the Mekedatu Dam Project?
The Mekedatu dam is a proposed multi-purpose project across the Cauvery river in Karnataka's Ramanagara district, near the border with Tamil Nadu. Karnataka plans to build the dam to generate hydroelectricity and supply drinking water to Bengaluru and surrounding areas. However, Tamil Nadu has strongly opposed the project, arguing that it would affect the flow of water to the state and violate the Cauvery Water Disputes Tribunal (CWDT) award and the Supreme Court's 2018 verdict.
Vijay's Appeal to PM Modi
In his letter, Vijay expressed deep concern over Karnataka's unilateral decision to proceed with the Mekedatu project without consulting Tamil Nadu. He stated, "The construction of the dam would severely impact the water availability for farmers and residents of Tamil Nadu, especially during drought years." He requested the Prime Minister to direct the Cauvery Water Management Authority (CWMA) to review the project and ensure that no construction takes place without a comprehensive assessment of its downstream effects.
Vijay also pointed out that the Supreme Court had earlier directed both states to resolve the issue amicably through negotiations. He urged PM Modi to facilitate a meeting between the chief ministers of Tamil Nadu and Karnataka to find a mutually acceptable solution. "The lives and livelihoods of millions depend on the Cauvery river. It is imperative that the central government steps in to prevent any further escalation of this dispute," he wrote.
Background of the Cauvery Water Dispute
The Cauvery water dispute is one of India's longest-running inter-state river conflicts, involving Tamil Nadu, Karnataka, Kerala, and the Union Territory of Puducherry. The CWDT award in 2007 allocated 419 TMC of water to Tamil Nadu, 270 TMC to Karnataka, 30 TMC to Kerala, and 7 TMC to Puducherry. However, Karnataka has consistently argued that the allocation is unfair and that the state's growing needs require more water. The Supreme Court's 2018 verdict largely upheld the CWDT award but reduced Tamil Nadu's share slightly to 404.25 TMC.
Current Status of Mekedatu
Karnataka has been pushing for the Mekedatu project since 2013, but Tamil Nadu has repeatedly raised objections before the CWMA and the Supreme Court. In 2022, the Supreme Court allowed Karnataka to conduct a feasibility study but barred any construction until further orders. Despite this, Karnataka has continued preparatory work, leading to tensions between the two states. In 2025, Karnataka Chief Minister announced that the state would proceed with the project after obtaining all necessary clearances, prompting Tamil Nadu to approach the Supreme Court again.
Vijay's letter comes amid growing political pressure in Tamil Nadu, where several parties have demanded that the central government intervene. The state government has also filed a petition in the Supreme Court seeking a stay on the project. Environmental groups have raised concerns about the ecological impact of the dam, including deforestation and displacement of local communities.
Reactions and Implications
Political analysts view Vijay's letter as a significant move, given his rising popularity in Tamil Nadu politics. His party, Tamizhaga Vetri Kazhagam (TVK), has been vocal on state issues, and this letter reinforces his stance on protecting Tamil Nadu's water rights. Karnataka officials, however, have dismissed the letter, stating that the project is within the state's rights and would not harm Tamil Nadu's interests. They argue that the dam would be built on Karnataka's portion of the Cauvery and would not impound more water than allowed.
The central government has yet to respond to Vijay's letter. Meanwhile, the CWMA is scheduled to meet next month to discuss the issue. The outcome of that meeting could determine the future of the Mekedatu project and the broader Cauvery water sharing agreement.
