The Mettur Reservoir will open on the scheduled date of June 12 for kuruvai cultivation in the delta districts. With the storage in the reservoir at 64.931 thousand million cubic (tmc) feet, the State will have no problem in opening the dam for irrigation. The current storage is sufficient to meet the irrigation demand for one-and-a-half months. To start with, about 5000 cusecs will be released which will gradually be increased to 15,000 cusecs over a fortnight. Last year, the dam was opened on July 18 as the storage was not comfortable.
