AIADMK leader Edappadi K. Palaniswami has voiced strong concerns over the proposed Mekedatu dam project in Karnataka, alleging that the state’s Congress government aims to make Tamil Nadu water-scarce. Addressing the media, Palaniswami criticized the DMK-led Tamil Nadu government for not taking a firm stand to protect the state’s water rights under the Cauvery Water Dispute agreements.
The Mekedatu project, which is planned across the Cauvery River in Karnataka, is intended to provide drinking water to Bengaluru and generate hydroelectric power. However, Tamil Nadu has raised objections, stating that the dam could have significant adverse effects on the availability of Cauvery water downstream, potentially impacting agriculture and drinking water supply.
Palaniswami pointed out that Tamil Nadu has already filed review petitions and legal pleas regarding the project, emphasizing that the state must ensure its water rights are fully protected. He argued that failure to act decisively could lead to a situation where Tamil Nadu faces severe water shortages. The AIADMK leader urged the state government to actively engage with the central authorities and the Cauvery Water Management Authority to prevent any unilateral actions by Karnataka that could compromise Tamil Nadu’s interests.
The dispute over the Mekedatu project is part of a long-standing contention between Karnataka and Tamil Nadu regarding sharing of Cauvery river waters. The Cauvery Water Dispute Tribunal and subsequent Supreme Court rulings have outlined water allocation for each state, but projects like Mekedatu have often led to renewed tensions.
Environmental and water management experts have pointed out that the construction of new dams upstream can affect river flow patterns, groundwater recharge, and ecosystem balance downstream. Farmers in Tamil Nadu, who rely on Cauvery water for irrigation, have repeatedly expressed concerns that Mekedatu could limit water availability during critical agricultural periods.
The Tamil Nadu government has consistently stated that any project on the Cauvery must ensure minimum guaranteed flows to protect the state’s agriculture, drinking water supply, and ecological needs. Several petitions in the Supreme Court and Central Water Commission have highlighted the potential negative impact of Mekedatu on these aspects.
In response to AIADMK’s criticism, the DMK government has reiterated that it is actively pursuing all legal and administrative channels to safeguard Tamil Nadu’s water rights. Officials have confirmed that the state will continue monitoring the project closely and present its objections at every appropriate forum.
As the debate continues, Mekedatu remains a flashpoint in Karnataka-Tamil Nadu water relations, reflecting broader challenges in inter-state river water management in India. Political parties in Tamil Nadu are using the issue to highlight governance and advocacy for state interests, emphasizing the importance of protecting water resources for agriculture, drinking needs, and overall sustainability.
Palaniswami’s statements underscore the continuing sensitivity of water disputes in South India and the political pressures on state governments to defend their water entitlements in ongoing negotiations and legal proceedings.
