Let me add few more points to the already posted information. Many kannada friends why the Hogenakkal has been chosen for the project and not mettur. Mettur reservoir is surrounded in the north by Shervaroyan hills, the meeting point of eastern ghats and a part of western ghats. It is practically impossible and extremely expensive to lay huge pipes thro' these mountains. Morover mettur is in lower riparian region than Hogenakkal, Dharmapuri and Krishanagiri districts.
Secondly, Hogenakkal can be the only ideal place from where huge quantities of water can be pumped due to its depth and its eastward inclination towards Dharmapuri. So the TN project is entirely genuine and valid
