Kaveri:  This is another holy river for the Hindus. Originating from Thalakaveri in the Sahyadri ranges of Karnataka, Kaveri carries a beautiful meaning on its name – ‘kaav’ means garden and ‘eri’ means a lake. In the agricultural and industrial life of the two states of Karnataka and Tamil Nadu, this river plays a very crucial role. Because of this, both the states have taken the water of this river as their main plank for verbal battle.

This 765-kilometer long river has a water-shed area of 87,900 square kilometer. Taking its origin from a place near the Arabian Sea of the west, Kaveri flows towards the opposite direction and joins the Bay of Bengal in the east. The main tributaries of Kaveri are Shimsha, Hemavati, Arkavati, Kapila, Honnuhole, Neyyel, Lokapavani, Amaravati, Lakshmana theertha, Kabani, and Bhavani. The Krishnarajasagar Dam on Kaveri is near the historic city of Mysore. The Kaveri has created two islets too in its Karnataka area – of Shivasamudra and Sreerangapatnam. Near Shivasamudra are two waterfalls of Bharachuki and Gaganachuki.

The Mettoor dam is built in the district of Salem in Tamil Nadu where too Kaveri has created two islets – at Hogenakal and Sreerangam. These are created as a result of the branching of the Kaveri at Sreerangam. After a couple of kilometers of the two branches join again. And it is here is the Grand Dam, believed to have been built in the second century A.D., at a length of 328 meters and a height of 20 meters. This dam of blocks of rock stands firm and fine, as a testimony to the expertise of the great builders of several centuries ago.
