Key highlights
Direct fact
In August 2026, the Tamil Nadu government’s petition on the Mekedatu dam project is listed for hearing before the Supreme Court on 31 August, with a Bench of Justices Vikram Nath and Sandeep Mehta.
Key specifics
- Tamil Nadu has sought a ban on any permission or order by the Cauvery Water Management Authority on the Mekedatu project.
- The petition argues that the Cauvery basin is a “deficit basin” and that even small new water projects cannot be allowed.
- The state says the Supreme Court’s final judgment bars upstream states from implementing new projects that affect downstream water supply.
- The petition cites Karnataka’s integrated storage structures on the Cauvery as holding about 218 TMC of water, rising to 327 TMC in monsoon.
- Tamil Nadu says the allocated share for Karnataka is 284.75 TMC, and any new dam for drinking water is unnecessary.
