Ahead of the release of water from the Stanley reservoir at Mettur and the Amaravathi dam, a flood warning has been issued to people living along the Cauvery in Karur and Tiruchi districts.
Although the quantum of water release from Mettur dam is yet to be decided, going by the current discharge of water from the reservoirs in Karnataka, public works department (PWD) officials expect the water release to be not less than 10,000 cusecs on Thursday.
If the current inflow into the Mettur dam continues for four to five days, there will be no option but to step up the quantum of release, though the requirement of water in delta districts is still on the lower side.
The water released from the Amaravathi dam will also flow into the Cauvery in Karur district within the next few days.
Although there has been fluctuation in the quantum of water release, PWD officials expect that at least 2,000 cusecs will be released at Mayanur, the confluence point of Amaravathi water.
Bracing for the heavy flow, PWD officials have begun work on determining the functionality of the shutter at Mukkombu upper anaicut.
Similarly, the shutters of Mayanur barrage on the upper stream of the Cauvery in Karur district, and the Left Main Canal and Right Main Canal have also been checked to test their efficiency.
Karur Collector T. Anbalagan told The Hindu that he had received information that the discharge would initially be nominal. However, chances were high for heavy discharge of water subsequently.
