Anakarai is a neighbouring place of Jayankondam at about 20 km in the Kumbakonam-Chennai State Highway. It is an island developed in the Cauvery river basin, known as Kollidam River. It is connected with the mainland with two regulator-cum-bridges. This century-old regulator irrigates most of the parts of this and neighbouring districts. The other one is now very weak and restricted for heavy vehicles. A new bridge proposed at this place is waiting for its green flag.Nearly 2000 families reside in this island. The main source of income of these families is agriculture and fishing. This place is very famous for its rich source of fresh water fishes. Another major attraction in Anakarai is the Villi Andavar temple in the western bank of the river. The Cholas built this temple in the west side of the island during their rule.
