"As on date, the storage capacity at Mettur Dam is only 41.11 tmcft (as against the full capacity of 120 tmcft) and therefore there is no possibility of releasing water from the dam," she said, adding, the move would allow paddy kuruvai (short-term) crop on over 1.5 lakh acres though it was taken up on 3.45 lakh acres last year.
Water from Mettur Dam was scheduled to be released on June 12.
Her announcement will help 80,000 pump-sets in the areas to draw ground water for crop-irrigation, she said.
Karnataka did not release "even a drop of" Tamil Nadu's due share of 10.16 tmcft of water from Cauvery for June, she said, adding, her demands to notify the final award on the Cauvery dispute in the union gazette besides asking Prime Minister Manmohan Singh to convene the Cauvery River Water Authority to discuss the issue have not been met with.
