All four dams in the Cauvery basin in the state have 26.17 TMC water Cauvery water is supplied to Mandya, Mysuru and Chamarajanagar, apart from Bengaluru By the end of November, water might be released only once in four days
According to the Supreme Court, Karnataka is required to release 3.8 TMC water to Tamil Nadu from September 21 to September 27. But considering the water storage in the reservoirs in the Cauvery basin, the state is nearly certain to face a water crisis.
Currently, all four dams in the Cauvery basin in the state have 26.17 TMC water. If Karnataka releases 3.8 TMC for seven days, the state is left with 22.37 TMC water. Out of this, 3 TMC will evaporate over a period of 10 months, leaving 19.37 TMC water for the state’s actual use.
As Cauvery water is supplied to Mandya, Mysuru and Chamarajanagar, apart from Bengaluru, Karnataka needs a total of 28 TMC water.
Currently, water is being supplied to rural areas once in two days. By the end of November, water might be released only once in four days. Again for Bengalureans, it will become a necessity to buy water from tankers.
