The dam was built in 1957 during Mr.K. Kamaraj's administration across the Amaravati River about 25 km upstream and south from Thirumoorthy Dam. Capacity of the dam has shrunk 25% from 4 tmcft to 3 tmcft due to siltation of the reservoir. during 2003-04, the Tamil Nadu Electricity Board proposed to install 4 MW electric generating capacity from the dam, which is now in operation.
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 Palni Hills above. Boating for tourists in the dam began on 14 January 2011.
