The Dravida Munnetra Kazhagam (DMK) has escalated its opposition to Karnataka's proposed Mekedatu dam project by filing adjournment motion notices in both the Lok Sabha and the Rajya Sabha on 19 July, demanding an urgent parliamentary debate on what the party describes as a direct threat to Tamil Nadu's water security and the livelihoods of millions of farmers dependent on the Cauvery River.

The Parliamentary Push

DMK parliamentary party leader T.R. Baalu submitted the adjournment motion notice in the Lok Sabha to the Speaker, calling for an immediate floor debate ahead of the Monsoon Session beginning 20 July. Baalu argued that Karnataka's unilateral push to construct a balancing reservoir across the Cauvery at Mekedatu would have far-reaching consequences for Tamil Nadu's farming communities, particularly those in the Cauvery delta who rely on the river for irrigation.

A parallel notice was filed in the Rajya Sabha by DMK floor leader Tiruchi Siva, who urged an immediate discussion on the dam's legal, environmental, and agricultural implications for Tamil Nadu. The coordinated twin-notice strategy signals a deliberate effort by the party to push the issue to the national stage at the earliest opportunity.

What the DMK Is Demanding

The party has urged the Centre to temporarily suspend all other scheduled parliamentary business and take up the Mekedatu matter as a question of urgent public importance. Beyond the debate itself, the DMK is pressing the Centre to intervene and prevent Karnataka from advancing the project until all interstate concerns are fully resolved.

The party has also reiterated its longstanding demand that the Centre ensure strict compliance with the Cauvery Water Disputes Tribunal award and the directions issued by the Supreme Court on inter-state water sharing.

The Mekedatu Dispute: Background

The Mekedatu project — a proposed balancing reservoir on the Cauvery in Karnataka's Ramanagara district — has been a persistent flashpoint between the two states. Karnataka argues the dam would help store water for drinking purposes and regulate flow, while Tamil Nadu and the DMK contend it would allow the upstream state to control releases and reduce the quantum of water reaching the lower riparian state.

The DMK has consistently maintained that the project cannot proceed without the explicit consent of lower riparian states. This is not the first time the party has raised the issue in Parliament — the Mekedatu dispute has resurfaced repeatedly whenever Karnataka signals forward movement on the proposal.

What Happens Next

With the Monsoon Session commencing 20 July, the DMK is expected to press vigorously for a comprehensive debate and seek a clear statement from the Centre on the project's status. Whether the Speaker and Rajya Sabha Chairman admit the adjournment motions will determine how quickly the issue reaches the floor. The outcome could also influence the broader political dynamics between the DMK-led Tamil Nadu government and the Centre ahead of the session.
