The Cauvery water-sharing dispute once again dominated proceedings in the Tamil Nadu Legislative Assembly as Chief Minister Joseph Vijay and Leader of the Opposition Udhayanidhi Stalin engaged in an intense debate over the Mekedatu Dam project and the state's response to Karnataka's plans.

Raising the issue in the Assembly, Udhayanidhi Stalin questioned the government about the concrete measures it had taken to prevent Karnataka from moving ahead with the Mekedatu Dam project. He argued that the government had failed to clearly explain its strategy and demanded greater transparency regarding efforts to safeguard Tamil Nadu's water rights.

The opposition leader also criticized the government for refusing to convene an all-party meeting on the issue. According to him, Karnataka had demonstrated political unity by bringing together all parties to defend the state's interests, whereas the Tamil Nadu government was reluctant to build a similar consensus. He maintained that a united political approach would strengthen Tamil Nadu's position in the long-standing river water dispute.

Responding to the allegations, Chief Minister Joseph Vijay stated that his government remained fully committed to protecting the interests of Tamil Nadu's farmers and citizens. He emphasized that every possible constitutional and legal step would be taken to safeguard the state's rightful share of Cauvery water.

The Chief Minister informed the Assembly that the government had already passed a resolution opposing the Mekedatu Dam project and had written to Prime Minister Narendra Modi expressing serious concerns over its possible impact on Tamil Nadu's water availability and agricultural sector.

Vijay also countered the opposition by referring to historical decisions related to the project, arguing that previous governments should also answer questions regarding approvals and policy decisions taken decades ago. He said the current administration was focused on finding practical solutions instead of engaging in political blame games.

The debate also shifted to Vijay's proposed visit to Bengaluru for talks with Karnataka. Udhayanidhi Stalin questioned why the government appeared to withdraw from the plan after reports of political opposition emerged. He alleged that the government had sent mixed signals regarding the proposed visit.

Defending his position, Vijay said dialogue with a neighbouring state should never be viewed as a sign of weakness. He argued that discussions remain an essential part of resolving disputes and maintaining cooperative federalism. According to him, meaningful dialogue is often the first step toward a peaceful resolution.

The Chief Minister further revealed that Karnataka Deputy Chief Minister D.K. Shivakumar had requested him to postpone the proposed visit due to prevailing tensions and ongoing protests related to the Cauvery issue. Vijay added that he had also been invited to jointly visit drought-affected regions in the Cauvery basin once the situation became more conducive.

Making an emotional appeal during the debate, Vijay said he was willing to endure criticism or even personal humiliation if it helped protect the interests of Tamil Nadu and its farmers. He asserted that public welfare was more important than personal prestige and reaffirmed his government's commitment to defending the state's rights.

The Cauvery water dispute and the Mekedatu Dam project have remained sensitive issues between Karnataka and Tamil Nadu for decades. The latest Assembly debate highlighted not only political differences but also the broader challenges of interstate water sharing, agricultural security, and cooperative governance. The issue is expected to continue influencing regional politics in the coming months.
