A political war of words erupted in the Tamil Nadu Assembly on Friday between Chief Minister Joseph Vijay and Leader of Opposition Udhayanidhi Stalin over the Cauvery water dispute and Karnataka’s proposed Mekedatu dam project. The heated exchange took place as the Opposition questioned the state government’s efforts to prevent the neighbouring state from moving ahead with the dam plan. Raising the issue during the Assembly session, Udhayanidhi Stalin accused the Vijay government of failing to take adequate steps to protect Tamil Nadu’s interests in the Cauvery river dispute. He demanded that the government explain the measures taken to stop Karnataka from proceeding with the Mekedatu dam project.

“The government must clarify in the Assembly what steps have been taken to stop Karnataka from going ahead with the Mekedatu dam,” Udhayanidhi Stalin said while questioning the state’s approach to the long-running water-sharing issue. Responding to the allegations, Chief Minister Joseph Vijay rejected the criticism and said his government had already taken steps to oppose the proposed dam. He pointed out that the Tamil Nadu Assembly had passed a resolution against the Mekedatu project and that he had also written to Prime Minister Narendra Modi expressing opposition to the move.

“We will do whatever it takes to safeguard the interests of Tamil Nadu farmers,” Vijay said, asserting that his government would continue to protect the state’s water rights. He maintained that the issue remained a priority for the administration, particularly because of its impact on farmers dependent on the Cauvery river system. The Chief Minister also turned the criticism towards the DMK, referring to the party’s past role in the matter. Vijay claimed that the DMK government in 1969 had initially allowed discussions related to the Karnataka project, seeking to highlight what he described as inconsistencies in the Opposition’s position.

The Mekedatu dam proposal has been a longstanding point of disagreement between Tamil Nadu and Karnataka. Karnataka has maintained that the project is intended to provide drinking water to Bengaluru and surrounding areas, while Tamil Nadu has opposed it, citing concerns over its potential impact on the flow of Cauvery water to the state. The Cauvery river dispute has historically been a sensitive political issue in both states, with governments often facing pressure from farmers and regional groups to protect their respective water interests. Any development related to river management or dam construction frequently triggers strong reactions from political parties and stakeholders.

The latest confrontation in the Tamil Nadu Assembly reflects the continuing political importance of the Cauvery issue ahead of future discussions on water management between the two states. Both ruling and Opposition parties have sought to position themselves as defenders of Tamil Nadu’s agricultural and water security concerns. While Vijay defended his government’s actions, Udhayanidhi Stalin continued to question whether enough was being done to prevent the Mekedatu project from advancing. The disagreement highlights the broader challenge of balancing interstate water-sharing agreements with the demands of regional politics and local communities dependent on river resources.
