Hi More than half of Kaveri is in TN. Why has TN not built dams in its territory to harness rain water? Why does it want a share of water harnessed by Karnataka? Kaveri does not generate water from the earth - it is fed by the monsoons. Logic of sharing kaveri water is like - my colony invests in a rain-water harvesting system and gets good results; the neighbouring colony then begs or rather demands as a right water from the system!! will the sane TN people get this simple issue please..
