The area in Cauvery basin of Karnataka is 36240 while that of TN is 48581. For any common man, no doubt TN is having more area in Cauvery basin. But try to analyse the reason for the area being less in Karnataka inspite of Cauvery running for 381 KMS which is 30 KMS more when compared to the flow in TN. Karnataka has more Dams and to store water it has lost quite a lot precious irrigation land. TN has no dams in the cauvery basin and all the land has been used for irrigation. Because of this the area in Cauvery basin is more for TN as compared to Karnataka.
