Aliyar Dam
It was builded by a great Indian leader called kamaraja. He didn't even studied but he was the leader at that time.
Just Now visited one of the best dam in India. Especially in Tamilnadu it was the well designed dam till the date. But those sunny days on India is like you're in sahara. That's why the water on the dam is very low. But it is a pleasure feeling to swim, when High temperature outside. Just Google it the dam name see how was it...
