The Cauvery Water Regulatory Committee (CWRC) on 28 July directed Karnataka to release 3,500 cusecs of water per day to Tamil Nadu for 15 days, triggering a political and administrative dilemma for the state as it battles one of its worst monsoon deficits in recent memory. Karnataka Water Resources Minister Ramalinga Reddy said the state government would act only after consulting Chief Minister D.K. Shivakumar, leaving the final call in abeyance.

What the CWRC Directed

The directive emerged from a meeting of Cauvery authorities on Tuesday, at which the CWRC instructed Karnataka to maintain a daily discharge of 3,500 cusecs to Tamil Nadu over a 15-day window. Speaking to reporters in New Delhi, Minister Reddy confirmed the order and said Karnataka was also weighing an appeal before the Cauvery Water Management Authority (CWMA).

'There was a meeting of the Cauvery Water Regulatory Authority today, and Karnataka has been directed to release 3,500 cusecs of water every day for 15 days. We require nearly 6 TMC of water ourselves. We also have the option of filing an appeal before the Cauvery Water Management Authority, and a decision will be taken after discussing the matter with Chief Minister D.K. Shivakumar,' Reddy said.

The Crisis at KRS Reservoir

The CWRC order arrives at a particularly fraught moment for Karnataka's water managers. The Krishna Raja Sagara (KRS) reservoir — the primary source of drinking water for Bengaluru, Mysuru, and Mandya — currently holds only about 16 TMC against its full capacity of roughly 46 TMC. Of that 16 TMC, nearly 5 TMC is dead storage and cannot be drawn upon for use.

The reservoir's inflow situation compounds the concern. During a normal monsoon, the KRS receives between 3,000 and 4,000 cusecs of inflow daily. This season, inflow has slumped to roughly 600 cusecs — a fraction of what is needed to replenish stocks. Authorities have already advised farmers to avoid cultivating water-intensive crops that depend on KRS supplies, and officials are reportedly planning to conserve available reserves primarily for drinking purposes through March or April next year.

Karnataka's Position and Legal Options

Minister Reddy was unequivocal about the state's predicament. 'We have not received sufficient rainfall. Our priority is to ensure drinking water for the people for the entire year,' he said. The state's argument — that it needs the water for drinking supply to millions of citizens — is expected to form the core of any appeal before the CWMA.

Notably, any release of 3,500 cusecs per day over 15 days would amount to a significant drawdown from already stressed reservoirs, directly threatening Bengaluru's summer water supply. The city, India's technology capital, is heavily dependent on the Cauvery River system for its drinking water needs.

What Happens Next

The Karnataka government is expected to convene discussions with Chief Minister D.K. Shivakumar before issuing a formal response to the CWRC. The state has two broad paths: comply with the directive or challenge it before the CWMA. Legal observers note that the CWMA appeal route has been used in previous inter-state water disputes, though outcomes have varied. With little indication of substantial rainfall in the coming weeks, the pressure on state authorities to protect drinking water reserves is likely to intensify before any resolution is reached.
