A bench headed by Justice R M Lodha, which three-days back had allowed the release of 2 TMC water, increased the amount by 0.44 TMC. This would be provided to Tamil Nadu on the recommendation of the Central Water Commission (CWC).
The bench also comprising justices J Chelameswar and Madan B Lokur directed Karnataka to release the water immediately.
The court passed the order after going through the report submitted by an expert committee of CWC, which said that only 10% of cultivated land in Tamil Nadu needs water.
The committee said that 50% of the arable land has already been cultivated, 40% is on the verge of being cultivated and only the remaining 10% requires water.
"Having heard the parties and taking consideration of the expert committee report, we are satisfied that the interest of justice would be met if Karnataka is directed to release 2.44 TMC of water," the bench said.
