Aliyar reservoir located in Aliyar village near Pollachi town in Coimbatore District, Tamil Nadu, South India. The dam is located in the foothills of Valparai, in the Anaimalai Hills of the Western Ghats.
The Aliyar Dam was constructed during 1959-1969 across the Aliyar river, mainly for irrigation purposes.
Aliyar Dam was inaugurated on 2 October 1962 (Gandhi Jayanti day) by then Prime minister of India, Pandit Jawaharlal Nehru, K Kamaraj, the Chief Minister of Tamil Nadu.
The project was commissioned in September 2002 to generate Hydro Electric Power.
