Kollidam River, river, east-central Tamil Nadu state, southeastern India. Formed by the northern bifurcation of the Kaveri (Cauvery) River just west of Srirangam, the Kollidam River flows in an easterly and then northeasterly direction for about 95 miles (150 km) and empties through several mouths into the Bay of Bengal roughly equidistant between the Puducherry (north) and Karaikal (south) sectors of Puducherry union territory on the coast. The Kollidam is the major northern stream of the Kaveri delta. The river was dammed in 1836 to help provide irrigation water for the delta, the most fertile and densely populated region of southern India, noted for its rice production. The town of Chidambaram lies on its banks.
