Cauvery flows about ~100 mile naturally in KN state and 72 mile artificial channel that KN govt built to divert water to more areas. But cauvery flows in ~320 miles inside Tamilnadu. Which state needs more water logically?. Lands in TN's cauvery basin are being cultivated for more than 2 millennia whereas Karnataka is trying to divert water to more far off districts artificially by building more than 12 dams. Tamilnadu is only fighting to get the legal share. You will not be satisfied even if you let the whole river flow in KN alone. Then you can think of the disaster which will submerge the southern part of KN entirely.
