Tamil Nadu Chief Minister C. Joseph Vijay has written to Prime Minister Narendra Modi, urging him to reject Karnataka's draft Detailed Project Report (DPR) for the proposed Mekedatu reservoir on the Cauvery river.
Vijay argued that the project violates the Cauvery Water Disputes Tribunal's final award and the Supreme Court's 2018 judgment, and would affect scheduled deliveries to Tamil Nadu.
The Mekedatu proposal has sparked a long-running dispute involving Karnataka, Tamil Nadu, Kerala, and Puducherry over river-water sharing.
Tamil Nadu officials have directed legal and water-management teams to take immediate measures to protect the state's rights and safeguard farmers.
Karnataka, however, remains committed to the reservoir plan and is proceeding with required documentation.
