Tamil Nadu Chief Minister J.Jayalalithaa on Thursday said her government will file an interim petition in the Supreme Court to secure release of Cauvery river water from Karnataka.Announcing this in the state assembly, Jayalalithaa said the petition will be filed in one or two days in the Apex court and, after appropriate court orders, the state will get its share of water as per the final award of the Cauvery Water Disputes Tribunal.The Chief Minister said Karnataka did not release water during June and July this year as per the tribunal award.She also said that both Karnataka and the central government have not replied to her letters on the release of Cauvery water.Moreover, owing to insufficient water at Mettur Dam, no water could be released for cultivation from there on June 12.If the state does not get adequate water for cultivation by the end of this month the Tamil Nadu government has formulated subsidy schemes worth Rs 64.3 crore for the benefit of farmers.
