What happened (Supreme Court guidance to Tamil Nadu on CWMA and “proportionate” Cauvery water)

The Supreme Court asked Tamil Nadu to raise its contention that Karnataka has not supplied the “proportionate” quantity of Cauvery water due, with the Cauvery Water Management Authority (CWMA) itself. The Supreme Court treated the core dispute as Karnataka’s alleged failure to provide water at the required levels, while noting that some water was present even though a deficit existed the previous day.

During the hearing, the Supreme Court considered these key points and directions:

- Tamil Nadu’s stand: Tamil Nadu said CWMA was not issuing directions to Karnataka to cover the shortfall. Tamil Nadu also stated that the shortfall based on the pro rata formula stood at 17.414 tmc ft as of August 23.

- Court’s observation: On the morning of the hearing day, the court noted that some water was available, even though a deficit had been recorded the previous day.

- CWMA reporting cycle: CWMA was scheduled to meet on August 25. The Supreme Court directed submission of an updated report. The Supreme Court posted further hearing for August 31.
