In the 92-year history of the Mettur Dam, this year marks the 20^th time that water has been released for delta irrigation on its customary date, June 12.
In 61 years, water was released after the scheduled date, and in 11 years, it was not released on time.
For the Kuruvai cultivation, from June 12 to September 15, a total of 135.52 TMC of water is required for 5.22 lakh acres in the delta region.
From September 15 to January 28, for Samba and Thaladi cultivation, 268.47 TMC of water is needed for 12.10 lakh acres.
The water release will also facilitate the generation of 460 megawatts of the hydro-electric power.
It is essentially for drinking water requirements of Chennai that receives water from the Veeranam tank, which, in turn, is fed by the Cauvery water through the Vadavar channel, branching off from the Lower Anicut on the Coleroon.
Last year in 2024, there was no opening occurred in June and that was the first time in the last five years the date has been missed.
The last time the dam missed its opening date was in 2019.
Its capacity is 120 feet and the storage level will be 93.47 TMC.
