Kollidam River:
ASI archaeologists recently found remains of a possible Sangam-era irrigation structure in the Kollidam river near Lalgudi, Trichy.
- It is a river in southeastern India flowing through the Tamil Nadu
- It is the northern distributary of the Kaveri River.
- It is also known as Kolidam and sometimes Coleroon in English.
- Formed by the northern bifurcation of the Kaveri River just west of Srirangam, the Kollidam River flows in an easterly and then northeasterly direction.
- It finally empties through several mouths into the Bay of Bengal.
- The town of Chidambaram lies on its banks.
