Karnataka rejects CWRC directive to release 4,000 cusecs of Cauvery water to Tamil Nadu

Bengaluru: Karnataka Water Resources Minister N. Chaluvarayaswamy has said the state cannot accept the Cauvery Water Regulation Committee’s (CWRC) directive to release 4,000 cusecs of Cauvery water daily to Tamil Nadu, citing inadequate reservoir storage and deficient rainfall in the Cauvery basin.

The Cauvery Water Management Authority (CWMA) has upheld the CWRC’s recommendation despite Karnataka presenting data on water availability, inflows and rainfall conditions, the minister said.

Karnataka had sought a reduction in the prescribed release from 4,000 cusecs to 3,000 cusecs, citing the prevailing conditions at the KRS, Kabini, Hemavathi and Harangi reservoirs.

According to the state government, releasing 4,000 cusecs continuously for 15 days would result in around 5.18 TMC of water flowing to Tamil Nadu.

Chaluvarayaswamy said Karnataka’s immediate priority was to safeguard drinking water requirements in towns and villages dependent on the Cauvery basin, including Bengaluru. Releasing additional water when reservoir levels and inflows remain low could create drinking water concerns during the summer, he said.

The minister said the government would consult its legal experts and decide on the next course of action. Chief Minister D.K. Shivakumar has also indicated that Karnataka plans to challenge the CWRC directive through legal channels.

Karnataka officials told the authority that rainfall deficiency and low inflows had made the situation critical, leaving limited scope for significant replenishment of the four major reservoirs in the immediate future. The state has maintained that adequate water needs to be retained for drinking water and other essential requirements.

Tamil Nadu, meanwhile, has maintained that it is yet to receive its pro-rata share of Cauvery water. At the CWRC meeting, the state reportedly cited a deficit of around 14.981 TMC at Biligundlu compared with its pro-rata entitlement.

The latest directive has once again brought the long-running Cauvery water-sharing issue between Karnataka and Tamil Nadu into focus. While Karnataka has stressed drinking water requirements and the prevailing rainfall and reservoir conditions, Tamil Nadu has sought its stipulated share of water.

The Karnataka government is now examining its legal options against the directive.
