Parambikulam Dam is an embankment dam on the Parambikulam River, [3] located in the Palakkad district in the Western Ghats of Kerala, India, ranks number one in India as well as in the top ten embankment dams in the world in volume in the year 2000.

The other projects are Lower Bhavani, Krishnagiri, Mani Muthuar, Cauvery delta, Aarani River, Vaigai Dam, Amravathi, Sathanur, Pullambadi, and Neyaru Dams.

The dam is operated and maintained by Tamil Nadu but the ownership rests with Kerala,[1][2] Per the agreement with Tamil Nadu, Kerala was supposed to receive 7.25 TMC feet of water per year from the Parambikulam-Aliyar Project of which the Parambikulam Dam is a part.

In 2004, Kerala did not receive any water after February 10, resulting in the drying up of paddy in thousands of acres in Chittur taluk.

[6] On 17 October 2012, Kerala and Tamil Nadu reached an accord on Parambikulam-Aliyar water.
