Tamil Nadu Chief Minister C. Joseph Vijay moved a special resolution in the state assembly Friday opposing Karnataka's proposed Mekedatu dam project [1, 2].
The move signals a hardening of the state's stance on water security. The resolution urges the central government to deny approval for the dam to protect Tamil Nadu's share of the Cauvery River water [1].
This dispute centers on the control of water flow from the Cauvery River, a vital resource for agriculture and drinking water in both states. Tamil Nadu views the proposed dam as a direct threat to its water rights, a long-standing point of contention between the two regional governments [1].
During the session at the Tamil Nadu State Legislative Assembly, the Chief Minister called for federal intervention to ensure the project does not proceed [1, 2]. The resolution seeks a formal commitment from the center to reject the project based on the potential impact on downstream water availability [1].
The resolution received support from other political entities, including the Congress and VCK, indicating a broad legislative consensus within the assembly to oppose the Karnataka-led initiative [1].
Officials in Tamil Nadu said that any construction at Mekedatu would allow Karnataka to unilaterally regulate water flow, potentially leaving Tamil Nadu with insufficient supplies during drought periods [1].
“Tamil Nadu views the proposed dam as a direct threat to its water rights”
The resolution elevates a technical water dispute into a formal legislative mandate, limiting the Tamil Nadu government's ability to compromise with Karnataka. By involving the central government, Chief Minister Vijay is leveraging federal authority to block the project, which may increase diplomatic tension between the two states over the shared Cauvery basin.
