If you dont understand the issues pls keep quiet, The final result is TN will get 419tmc, but not completly from Karnataka, TN will get 217 from karnataka then remaining water will get from other rivers & rainfalls (Which is calculated from average rainfalls of previous years)....The final Judgement says TamilNadu is Entitled for 417tmc water in Kavery which is completly not from karnataka, understand the terms carefully.
