Supreme Court Directs Karnataka to Comply with CWMA Cauvery Water Release Directions to TN

Summary

On 17 August 2026, the Supreme Court of India directed the Karnataka government to ensure compliance with the Cauvery Water Management Authority's (CWMA) direction on release of Cauvery water to Tamil Nadu, while deferring further hearing in the matter by about a week.

What Happened

A bench of Justices Vikram Nath and Sandeep Mehta heard a plea filed by the Tamil Nadu government alleging that Karnataka had not fully complied with directions issued by the Cauvery Water Regulation Committee (CWRC) and the CWMA. The CWRC had earlier directed Karnataka to release 12,000 cusecs of water daily to Tamil Nadu for 15 days from 12 August 2026, a decision upheld by the CWMA. Senior Advocate C. S. Vaidyanathan, appearing for Tamil Nadu, submitted that the state was not receiving its due share and was unable to release adequate water to farmers. Karnataka told the court that the flow had crossed 12,000 cusecs as of the morning of 17 August, citing recent rainfall in Cauvery catchment areas. The bench directed Karnataka to continue adhering to the CWMA's directions and posted the matter for further hearing around 24 August 2026, also calling for a status report from the CWMA.
