The Tamil Nadu government announced that water will be released from the Mettur Dam for 45 days starting September 1, 2026, to support the Cauvery Delta irrigation and drinking water needs.
Why it matters

- The initial usable water storage at the start of the 2026-2027 irrigation year was 41.223 TMC.
- The minimum storage of 10 TMC had to be maintained previously, restricting continuous release.
