Veeranam Lake

Veeranam Lake is a large man-made reservoir near Kattumannarkoil in Cuddalore District, Tamil Nadu. Constructed in the 10th century during the Chola period and originally called Veeranarayanam Eri, it extends about 16 kilometres in length. Fed by the Kollidam River via the Vadavaru River, it serves as a major irrigation source and supplies drinking water to Chennai through the Veeranam Water Supply Project.

Visitors can expect a vast, shallow freshwater reservoir with a long earthen bund stretching for kilometres, surrounded by agricultural fields and rural villages. The site offers open views of the water spread, earthen embankments, sluices and inlet channels. There is no formal developed promenade; the experience is primarily sightseeing, photography and observing seasonal water levels, migratory birds in winter and local fishing activity along the bund road.

Veeranam Lake was constructed between 907 and 955 CE by Chola prince Rajaditya Chola, son of Parantaka I, and was originally named Veeranarayanam Eri after Parantaka's title Veeranarayanan. The 16 km long lake was created as a major irrigation tank to store floodwaters of the Kollidam River and is considered an outstanding example of Chola water management engineering.

The lake has sustained agriculture in the Cuddalore and Chidambaram region for over a millennium and remains culturally important as a historic Chola water structure. In modern times it gained significance through the Veeranam Water Supply Project which channels water to Chennai for drinking water needs, linking the rural reservoir to urban water security.
