"The government should not release Cauvery water to our neighbour even though it will attract contempt of the Supreme Court order," KPCC President G Parameshwar told reporters in Belgaum.
He said a Congress delegation would meet Prime Minister Manmohan Singh in Delhi and submit to him facts about the "distressing situation" prevailing in the state due to drought and water shortage problems.
The KPCC chief also faulted the state government for its "failure" to effectively present the Cauvery water sharing issue before the Supreme Court, Cauvery River Authority (CRA) and Cauvery Monitoring Committee (CRM).
The government had not taken Congress into confidence over the issue, Mr Parameshwar said. "It did even consult us before meeting with Tamil Nadu Chief Minister J Jayalalithaa when she visited Bangalore for talks on the issue," he said.
The Supreme Court had yesterday directed Karnataka to release 10,000 cusecs of Cauvery water per day to Tamil Nadu and asked CMC to hold its meeting to decide the amount of water required by the states.
The Supreme Court had also said its interim order would continue till CMC filed its report. It asked the committee to meet today or tomorrow and posted the case for further hearing on December 10.
