Site description Veeranam lake is situated in Cuddalore district, about 25 km west of Chidambaram town. It is one of the biggest and oldest lakes in Tamil Nadu. The Chola King Paranthaga constructed this lake in the 9th century AD. The book Ponniyen Selvan authored by Kalki in 1950 gives information on this lake, stating that it was constructed over 1,000 years ago by Prince Rajathithar, son of Paranthaga Cholan. The lake was originally called Veeranarayanan lake. The lake is about 16 km long and 8 km broad with a waterspread of about 15 sq. km. There are 34 sluices around the lake through which about 40,000 acres of two talukas, namely Chidambaram and Kattumanarkoil receive irrigation. The lake is fed by Vadavar river and Sengal stream. Under the current New Veeranam Project, parts of the lake were desilted recently. Veeranam Lake has a rich aquatic plant diversity with submerged, floating and emergent species. In several parts of the lake, mats of reeds and Ipomoea carnea occur. The trees found in the surrounding areas, islets and on the bunds are Acacia nilotica, Prosopis chilensis, Thespesia populnea, Pithecelobium dulce, Borassus flabellifer, Ficus benghalensis, F. religiosa and Azadirachta indica.
