Introduction
Intervening to protect the agricultural interests of delta farmers during the crucial Kuruvai and Samba cultivation seasons, the Supreme Court of India on 17 August 2026 decided to closely monitor the ongoing Cauvery water-sharing progress, directing strict compliance with the release orders issued by the Cauvery Water Management Authority (CWMA) and the Cauvery Water Regulation Committee (CWRC).
Legal Arguments & Water Distress Metrics
Senior advocate C.S. Vaidyanathan, representing the State of Tamil Nadu, presented pressing hydrological evidence before the apex court bench:
- Non-Compliance with CWMA Orders: Tamil Nadu highlighted cumulative water deficits in realized flows at Biligundlu, urging Karnataka to release the stipulated quantum of water strictly as per the distress-sharing formula mandated by the Cauvery Water Disputes Tribunal (CWDT) as modified by the Supreme Court in 2018.
- Protecting Standing Crops: Stressed that regular water releases are vital to sustain the standing Kuruvai and expanding Samba paddy acreage across Thanjavur, Tiruvarur, Nagapattinam, and Mayiladuthurai districts.
- Judicial Oversight: The Supreme Court affirmed that CWMA directives are legally binding statutory orders and directed both states to submit periodic fortnightly compliance affidavits.
