Kamaraj Sagar Dam

Kamaraj Sagar Dam, also known as Sandynalla Reservoir, is a dam and reservoir located about 10 km from Udhagamandalam (Ooty) in the Nilgiris district of Tamil Nadu. Built across the Sandynalla stream, it supplies drinking water to Ooty and surrounding settlements. Surrounded by Wenlock Downs grasslands, pine forests and Nilgiri hills, the reservoir is noted for its scenic setting and is a popular stop for sightseeing and photography en route to Pykara.

Visitors can expect a large, calm reservoir surrounded by open grasslands of Wenlock Downs, pine plantations and rolling Nilgiri hills. The site offers open views of the water and surrounding landscape, with roadside viewpoints for photography and short walks along the periphery. There are no boating facilities; the experience is primarily sightseeing, picnicking and enjoying the quiet natural setting on the Ooty to Pykara route.

The dam is built across the Sandynalla stream and is named after K. Kamaraj, former Chief Minister of Tamil Nadu. It was constructed to augment the drinking water supply for Udhagamandalam and nearby settlements and is also documented as Sandynalla Reservoir.
