Amaravathi Dam at Amaravathinagar, 25 km south on NH 17 from Udumalpet, is located in Indira Gandhi Wildlife Sanctuary in Tiruppur district, Tamil Nadu, India. The 9.31 km², 33.53 m deep Amaravathi Reservoir was created by this steep dam. It was built primarily for irrigation and flood control and now also has 4 megawatts of electric generating capacity installed.
It is notable for the significant population of Mugger Crocodiles living in its reservoir and catchment’s basin. There is a well laid-out park where one may climb steep steps on the dam to have a picturesque view north of the plains below and south to the Anaimalai Hills and Palani Hills above.
This place is being developed as a District Excursion Centre for tourism.
