The meeting of the Cauvery River Authority failed to produce a solution with both Karnataka and Tamil Nadu rejecting Prime Minister Manmohan Singh's award of 9000 cusecs of water to save standing crops in the delta region.
In protest against the award, Karnataka chief minister Jagdish Shettar staged a walkout, saying the state was not ready to give "even a drop of water" to Tamil Nadu.
Tamil Nadu chief minister J Jayalalithaa spoke in the same vein calling the meeting a "totally disappointed" affair and declared that the state would move the Supreme Court.
On its part, the Centre said the Prime Minister's decision was taken keeping in mind the survival of crops of both the states and maintained it cannot prevent any state from moving court.
After hearing both sides, Singh ruled that Karnataka release 9000 cusecs of water each day for 25 days from tomorrow to October 15 after it refused to accept Tamil Nadu's demand for 2 tmcft water for 24 days or 1 tmcft for 30 days.
