Bhavanisagar Dam

Bhavanisagar Dam is a major earthen dam built across the Bhavani River at Bhavanisagar in Erode District, Tamil Nadu, about 16 km west of Sathyamangalam. Completed in 1955, it is among the largest earthen dams in India and the world, stretching about 8 km in length. The dam creates a large reservoir that supports irrigation and provides scenic views of water, surrounding hills and a landscaped park frequented by visitors.

Visitors can expect a long earthen dam wall with a large reservoir on one side and the Bhavani River valley on the other. The site includes a landscaped park and garden area near the dam with viewpoints for photography and sightseeing. Views extend over the water spread and distant hills of the Western Ghats. Boating is sometimes available in the reservoir area when water levels permit, and the surroundings are open and breezy.

Bhavanisagar Dam, also known as Lower Bhavani Dam, was constructed between 1948 and 1955 across the Bhavani River as one of the first major irrigation projects after independence. Built at a cost of about Rs. 2.10 crores, it was inaugurated in 1955. The dam was designed to provide irrigation to over 2 lakh acres in Erode, Tiruppur and Karur districts through the Lower Bhavani Project canal system.

The dam and its reservoir are central to the agrarian economy of western Tamil Nadu, supporting paddy, sugarcane and turmeric cultivation. The park and reservoir area serve as a popular recreational and picnic destination for local communities and visitors from nearby towns.
