Just because tamilnadu was under british presidency in 19th century and they governed large parts of south india, they could bulldoze the mysore maharaja to do their bidding. and moreover since mysore region lacked the funds, they could not build any dams like what british government did in building mettur dam.probably if Sir Visveswaraiah had not built KRS, we would not have been eligible to draw even one tmc for our needs. Just because of mettur dam, tamil provinces increased their cultivation area and not their right because they dont get so much of rains in their area. Now that we have increased our cultivated area to take care of our food needs, tamil nadu cannot use an 150 year old story to demand excess share. Instead of wasting water and cultivating wetland cultivation of rice and shouting that they dont have sufficient water, let the tamilnadu government teach its farmers to use water in more efficient way like sprinklers, drip irrigation etc which is found to be scientifically tested method and requires only 50% of the water required. If they do so, they will have excess water .
