Puducherry | August 31, 2026: The Puducherry Legislative Assembly on Monday adopted a unanimous resolution opposing the proposed Mekedatu dam being planned by the Karnataka government, saying the project would be against the interests of the Union Territory and inconsistent with the final award of the Cauvery Water Disputes Tribunal, which the Supreme Court has upheld.
Assembly urges Centre to intervene
Moving the resolution, Chief Minister N. Rangasamy told the House the Centre should not permit construction of the dam, which is located about five kilometres from the Tamil Nadu border. The Assembly called on the Union government to restrain Karnataka from taking any further action on the project without the consent of the Cauvery basin states, including Puducherry.
"The Centre should not permit construction of the dam," the Chief Minister said, according to proceedings.
The resolution, initially introduced as a private member’s motion, was adopted as a government resolution after discussion in the House. The Assembly also resolved that the Puducherry administration would pursue all administrative and legal measures necessary to protect the Union Territory’s water entitlements and safeguard the interests of farmers in the Karaikal region.
Focus on Karaikal and water rights
Speakers in the Assembly highlighted concerns that the Mekedatu project could affect the quantum and timing of flows in the Cauvery basin, with potential consequences for irrigation and drinking water supply in Karaikal, the enclave of Puducherry on the east coast. The resolution underlined Puducherry’s entitlement under the tribunal award and invoked the Supreme Court’s affirmation of that award.
There was cross-party unanimity in the House on the need to defend the Union Territory’s claims. The Assembly collectively endorsed the state government’s stated intention to use both administrative channels and legal remedies to prevent any diminution of allocated water.
Proceedings and adjournment
Pro-tem Speaker A. Anbazhagan later announced that the Assembly had been adjourned sine die following the adoption of the resolution. The sitting had begun on August 24 and ran for six days, according to the official record of the House.
- What was adopted: Unanimous resolution opposing the Mekedatu dam.
- Who moved it: Chief Minister N. Rangasamy.
- Next steps signalled: Administrative and legal action to protect water rights and farmers in Karaikal.
The Assembly's position will now be conveyed to the Union government and, as indicated in the resolution, may form the basis for further representations to central authorities and, if necessary, litigation to uphold Puducherry's entitlements under the Cauvery adjudication.
Background and wider context
The Mekedatu proposal has previously been a flashpoint between Karnataka and downstream riparian states. The Puducherry resolution frames the matter through the prism of the Cauvery Water Disputes Tribunal's final award and the Supreme Court's endorsement of that award — legal instruments that Puducherry says determine its share in the river's flows.
By adopting a unanimous resolution, the Assembly sought to present a united front that spans party lines, underlining the political sensitivity of river-sharing issues in the region. The specific emphasis on protecting Karaikal farmers signals concern over agriculture-dependent livelihoods in the Union Territory.
| Item | Detail |
|---|---|
| Assembly action | Unanimous resolution opposing Mekedatu dam |
| Moved by | Chief Minister N. Rangasamy |
| Location of proposed dam | About 5 km from Tamil Nadu border |
| Sitting dates | Six-day sitting beginning August 24; adjourned sine die August 31 |
The resolution requests the Centre to ensure no unilateral steps are taken by Karnataka that could alter the status quo without the concurrence of all Cauvery basin states, including Puducherry. It remains to be seen what form the Union government's response will take and whether the matter will be pursued further in courts or through inter-state negotiations.
Officials in Puducherry are now expected to prepare formal representations and legal assessments outlining the potential impact of the Mekedatu project on the Union Territory's water allocations. Any subsequent administrative measures or litigation will be watched closely by farmers and water users in Karaikal, and by neighbouring states that are parties to the Cauvery adjudication.
