NEW DELHI/BENGALURU/CHENNAI, AUG 11
The Cauvery dispute has once again moved from reservoirs to the courtroom, with Karnataka weighing a Supreme Court challenge after the Cauvery Water Management Authority (CWMA) upheld the direction to release 12,000 cusecs of water daily to Tamil Nadu for 15 days.
The latest order has brought the long-running inter-State water dispute back into sharp focus, with Karnataka signalling that it is prepared to explore every available legal avenue while Tamil Nadu continues to press for implementation of the Cauvery-sharing mechanism.
Karnataka Additional Chief Secretary Gaurav Gupta, who participated in the CWMA meeting, said the State was examining its options, including approaching the Supreme Court.
Gupta indicated that Karnataka expected its plea to be considered alongside a pending Cauvery-related matter listed before the apex court on August 13.
“The direction given by the CWMA is to reiterate the decision taken by the Cauvery Water Regulation Committee. The committee had decided to release 12,000 cusecs for a period of 15 days, to be realised at Biligundlu,” Gupta told reporters in New Delhi.
The direction translates to a substantial flow over the 15-day period, placing fresh pressure on Karnataka’s reservoir management even as the State argues that water availability and rainfall conditions must be assessed dynamically.
Karnataka: “We will examine all” legal options
Gupta said the State would study the CWMA decision comprehensively before deciding its next legal step.
“There are different dimensions to this issue. There are different aspects to the problem. We will examine all of them comprehensively and then take appropriate action regarding the legal remedy available to us, what measures we can take from a legal perspective and how we can secure justice for the state,” he said.
The statement leaves open the precise form of Karnataka’s legal challenge, but makes clear that the State is considering intervention by the Supreme Court.
The timing assumes significance with a Cauvery-related matter already scheduled for hearing on August 13.
Gupta also stopped short of characterising the CWMA’s decision as permanently disadvantageous to Karnataka, pointing instead to the rapidly changing hydrological situation.
“What has happened now is that this is a very dynamic situation. Although prima facie we said that we had been treated unfairly, subsequently, when there was more rainfall in the Cauvery basin, we were able to manage the situation,” he said.
The Karnataka government’s position is therefore built around two strands: challenging what it considers an inequitable water-release burden while simultaneously recognising that rainfall and inflows can materially alter the basin situation.
The 12,000-cusec flashpoint
The latest development follows a series of recent Cauvery regulatory interventions.
The Cauvery Water Regulation Committee (CWRC) is the technical body that assesses the prevailing basin situation and makes recommendations, while the CWMA considers and takes the broader management decision.
The latest direction has renewed Karnataka’s concerns over its own water requirements, while Tamil Nadu has maintained its claim to water under the established Cauvery-sharing framework.
The dispute is particularly sensitive because the water released at Biligundlu becomes the measurable point for determining the flow reaching Tamil Nadu.
The Supreme Court has previously emphasised that the expert authorities under the Cauvery mechanism are required to assess rainfall, reservoir storage, inflows, irrigation requirements and drinking-water needs while determining releases. In a September 2023 order, the apex court recorded that the CWRC and CWMA considered factors including rainfall deficits, reservoir storage and Karnataka’s drinking-water requirements while assessing a release direction.
Politics, farmers and reservoirs collide
The latest decision has also intensified political pressure within Karnataka.
Recent reports said the State government was preparing to deliberate on its response, with Chief Minister D K Shivakumar convening political consultations amid renewed opposition from farmers and Kannada organisations.
The immediate concern is not merely the volume of water but the competing demands on the Cauvery basin—drinking water, irrigation, reservoir storage, downstream requirements and the need to comply with directions issued under the established water-management framework.
The issue has acquired an additional political edge because Karnataka has repeatedly argued that its water position cannot be assessed independently of actual rainfall and reservoir inflows.
Earlier in the current cycle, the CWMA had upheld a lower CWRC direction requiring Karnataka to ensure 3,500 cusecs at Biligundlu for 15 days, despite Karnataka’s objections.
The jump to the latest 12,000-cusec direction therefore represents a sharp escalation in the immediate release requirement.
August 13: The next legal flashpoint
For both States, the next major development could come from the Supreme Court.
Karnataka is examining whether and how to challenge the latest regulatory decision, while a pending Cauvery matter is already listed before the apex court on August 13.
That makes the next few days particularly significant.
For Karnataka, the legal argument is likely to revolve around the factual and hydrological basis for the quantum directed to be released and the State’s competing water requirements.
For Tamil Nadu, the larger issue remains the implementation of the established Cauvery-sharing arrangement and the actual flow reaching its territory.
The dispute once again demonstrates the difficulty of converting a tribunal-backed and court-recognised water-sharing framework into a workable arrangement during periods of changing rainfall and reservoir conditions.
The Cauvery may be flowing, but the legal current is rising—Karnataka now looks to the Supreme Court as the 12,000-cusec order puts the inter-state water equation under fresh strain.
