Tamil Nadu moves Supreme Court over Cauvery water dispute with Karnataka

The development comes in the wake of Karnataka chief minister DK Shivakumar’s remark that the Mekedatu reservoir is the long term answer to the Cauvery dispute, arguing that Tamil Nadu would receive most of its advantages.

Shivakumar on Sunday said, “If the Mekedatu reservoir is built, nearly 90% of the benefit would go to Tamil Nadu, more than Karnataka. At no point can that water be diverted back to Bengaluru. Anyone can visit the project site and understand the facts.”

Tamil Nadu has been opposing the Shivakumar government’s stand and in June 2026, the Tamilaga Vettri Kazhagam (TVK) government passed a unanimous resolution against the proposal in assembly to construct a dam at Mekedatu.
