Supreme Court Defers Cauvery Water Dispute to September 15
The Supreme Court on Monday deferred the hearing on the Cauvery water dispute to September 15, after Tamil Nadu sought directions for Karnataka to clear the backlog in water releases and Karnataka said it was currently releasing more than the stipulated quantity. A bench of Justices Vikram Nath and Sandeep Mehta directed the parties to place subsequent developments on record and listed the matter for further hearing.
During the hearing, senior advocate CS Vaidyanathan, appearing for Tamil Nadu, alleged that Karnataka had failed to clear the accumulated shortfall despite the issue being recorded by the Cauvery Water Management Authority (CWMA). He submitted that nearly 24,700 acres of agricultural land in Tamil Nadu depended on Cauvery water and pointed to a substantial deficit in the flows recorded at Biligundlu, a riverside village on the border between the two states.
"I have come before my Lords. There is no other forum. There should be some consideration as to why my backlog should not be cleared," Vaidyanathan submitted, urging that Tamil Nadu's demand for clearing the accumulated deficit be reconsidered.
Appearing for Karnataka, senior advocate Shyam Divan said the State had released 9,888 cusecs on August 30 against the stipulated 9,000 cusecs and was releasing over 11,000 cusecs on Monday. "We have released an excess amount as of 8 am this morning," Divan said, adding that Karnataka would endeavour to maintain the required 9,000 cusecs.
The bench noted that Karnataka had increased its release from 11,000 to 12,000 cusecs from August 12. The court also observed that Karnataka was already releasing the 9,000 cusecs being sought by Tamil Nadu.
CWMA Remedy Highlighted
The Supreme Court repeatedly told Tamil Nadu that any challenge to the decision of the CWMA would have to be made before the appropriate forum. The bench said that if Tamil Nadu sought water over and above what the CWMA had directed, the authority's decision would have to be challenged appropriately.
Vaidyanathan informed the court that Tamil Nadu had sought a review of the CWMA decision on August 27, and urged the authority to reconsider the state's request. The Court observed that the authorities were considering the issue and passing orders every 15 days, and said the next CWMA order could take into account the submissions of both states.
The Court also directed the parties to place subsequent developments on record, and posted the matter for September 15.
Background of the Dispute
The hearing on Monday was part of a long-standing dispute over the sharing of Cauvery river water. Tamil Nadu had moved the Supreme Court on August 3, claiming that the quantity allocated by the Cauvery Water Regulation Committee (CWRC) and released by Karnataka was far below its due share in a rain-deficient year. The CWMA and the CWRC were reviewing the matter every 15 days, with next orders pending based on the submissions of the states.
On August 17, the Supreme Court had asked Karnataka to comply with the CWMA's direction. Tamil Nadu also filed an application seeking enforcement of the CWMA's July 30 direction requiring Karnataka to release 3,500 cusecs of water per day at Biligundlu for 15 days starting July 29. The DMK, represented by AKS Vijayan, had approached the Supreme Court seeking enforcement of the CWRC's July 28 direction, which was upheld by the CWMA.
Tamil Nadu to Open Mettur Reservoir Gates
Separately, Tamil Nadu Chief Minister C. Vijay will visit Salem district on Tuesday to open the sluice gates of the Stanley Reservoir at Mettur, facilitating the release of Cauvery water for irrigation in the delta districts. The Chief Minister is scheduled to open the dam gates at 10 am. The water release is planned for 45 days from September 1, subject to the reservoir's storage levels and inflow conditions.
The opening of the Mettur dam is traditionally scheduled for June 12 every year to facilitate the cultivation of kuruvai, a short-duration paddy crop in the Cauvery Delta region. However, the exercise was deferred this year due to inadequate rainfall in the Cauvery basin and low storage levels in the reservoir. This will be Vijay's first visit to Mettur after assuming office as Chief Minister on May 10.
The opening of the dam comes amid the continuing water dispute, as Tamil Nadu says it needs the water for its farmers while Karnataka maintains it is complying with the authorities' directions.
