The long-running dispute over sharing the Cauvery river waters has returned to the legal forefront. The State of Tamil Nadu informed the Supreme Court that it will raise its concerns before the Cauvery Water Management Authority regarding the shortfall in its proportionate share of river water. Following this submission, the top court scheduled the matter for a detailed hearing on August 31.
A Supreme Court bench comprising Justice Vikram Nath and Justice Sandeep Mehta took up Tamil Nadu’s plea seeking the strict enforcement of regulatory orders requiring Karnataka to release water. The dispute centers on whether the downstream state is receiving its fair and proportionate allocation during periods of low rainfall and reduced reservoir storage.
During the proceedings, senior counsel representing Tamil Nadu noted that while some water had reached the state after initial shortfalls over the weekend, the broader issue of accumulated deficits remained unresolved. The state pointed out that current directions from the regulatory authority have not mandated making up the backlog in the proportionate quantity of water owed.
Under the statutory framework governing river basin operations, the regulatory authority is tasked with reviewing actual water yields, monitoring storage levels, and assessing usage at regular intervals. Tamil Nadu argued that these assessments must account for proportional distribution, especially given that Karnataka holds an estimated 78 thousand million cubic feet (TMC) of water across its Cauvery reservoirs.
The state’s primary concern stems from a significant gap between the water received and the entitlements outlined in established water tribunal awards. Earlier filings highlighted that Tamil Nadu had received only a fraction of its scheduled allocation, resulting in a substantial cumulative deficit even after adjusting for lower basin inflows this season.
Karnataka has previously stated that it complies with regulatory release targets as storage conditions permit, noting that severe distress and low rainfall across the upper Cauvery basin have created acute local challenges. While release volumes fluctuated during earlier stages of the season, recent reports indicated that discharge rates had improved to align with mandated levels.
The Supreme Court had earlier asked Karnataka to adhere strictly to the authority’s orders and directed the regulatory body to submit a comprehensive compliance and status report. With both states presenting contrasting positions on proportional distribution, the bench posted the matter for next Monday to evaluate updated water flow records and reservoir data.
The outcome of the upcoming regulatory meetings and the subsequent Supreme Court hearing will be crucial in setting water-sharing parameters for the remainder of the monsoon season, providing essential clarity for agricultural communities and water management authorities across both states.
