Tamil Nadu Chief Minister Vijay wrote to Prime Minister Narendra Modi urging the central government to stop Karnataka's Mekedatu reservoir project [1].

The dispute centers on the control of the Cauvery River, a critical water source for agriculture in both states. Any alteration to the river's flow through the construction of a new reservoir could significantly reduce the water available to Tamil Nadu farmers, escalating long-standing regional tensions.

In his letter to the Prime Minister, Vijay said that the Mekedatu project violates the Cauvery Water Disputes Tribunal award [1]. He also cited a 2018 [2] Supreme Court judgment as a legal barrier to the project's implementation [1].

The Chief Minister's request comes ahead of his planned visit to New Delhi [2]. The communication emphasizes the need for the central government to intervene to protect the water rights of farmers in Tamil Nadu, who rely on the river for their livelihoods [1].

The Mekedatu project, proposed by Karnataka, aims to store water and generate power. However, Tamil Nadu maintains that such a project would allow Karnataka to unilaterally control the flow of water, effectively bypassing the legal frameworks established to share the resource equitably [1].

This legal and political standoff has persisted for years, with both states frequently seeking judicial intervention to ensure their respective water quotas are met. The current escalation reflects a renewed push by the Tamil Nadu administration to secure a formal rejection of the project from the federal level [2].

Tamil Nadu Chief Minister Vijay wrote to Prime Minister Narendra Modi urging the central government to stop Karnataka's Mekedatu reservoir project.

The clash over the Mekedatu reservoir is not merely a construction dispute but a strategic struggle over water security. By invoking the 2018 Supreme Court ruling and the Tribunal award, Tamil Nadu is attempting to frame the issue as a matter of legal compliance rather than a political disagreement. If the central government intervenes, it could solidify the legal restrictions on Karnataka's river management; if it remains neutral, the dispute is likely to return to the courts, further delaying regional infrastructure and agricultural planning.
