prashanthmanae, your name prashanth is good and i do not know what does manae means. Karanataka belongs to India and so also the cauvery belongs to India and the indians. Please do not be under the false illusion that karnataka is a different territory, because karnataka is a part of India and cauvery river is a small rivulet and is a part of India alone. Be good and think nationalistic, not just for the state where you live and were born, but our complete Nation.
