Chief Minister C. Joseph Vijay of Tamil Nadu has travelled to Bengaluru to meet Karnataka’s Deputy Chief Minister D.K. Shivakumar. The aim is to press Karnataka, the upper riparian state, to release the water share allotted to Tamil Nadu under the Cauvery Water Disputes Tribunal (CWDT) award of 2007, later modified by the Supreme Court in 2018.
Key Developments
- Vijay’s visit marks a shift from Tamil Nadu’s long‑standing reliance on adjudicatory mechanisms to direct bilateral talks.
- The demand is for Karnataka to release at least 3 tmc ft more water, raising the total to about 6.5 tmc ft for the June‑July period.
- Political parties, farmer groups, and water experts criticize the move, saying it bypasses the Cauvery Water Management Authority (CWMA) and the Cauvery Water Regulation Committee.
- There is concern Karnataka may link the talks to the controversial Mekedatu dam project.
Important Facts
Between 1 June and 23 July 2026, Tamil Nadu was entitled to receive roughly 32 tmc ft of water. It actually received only about 3.5 tmc ft. The shortfall is attributed to deficient southwest monsoon rainfall and Karnataka’s proportional reduction formula. Historically, Tamil Nadu has preferred court‑based adjudication, rejecting earlier offers for talks from Karnataka leaders.
