Introduction

Locally called Kallanai, the Grand Anicut dam was built on the Cauvery River in the 2nd century by Chola king, Karikalan. This massive structure was later reinforced by the British. Grand Anicut is believed to be one of the oldest water-diversion structures in the world that continues to be functional. Slicing through the Erode and Salem districts, the Cauvery River proceeds to join the Bhavani River in the town of Bhavani, home to the Sangameswarar temple. It is an important pilgrimage site at the confluence of two rivers. At Trichy, the Cauvery River gushes past the historic Rock and cuts a tributary at the Srirangam island.

Made of unhewn stones, the Kallanai dam is 1080-foot long (329 meters) and 60-foot wide (20 meters) across the main stream of the Cauvery. Originally, the structure was built to divert the river water through canals across the fertile delta region for irrigation. Despite technological innovations, the dam is regarded as an engineering marvel that has inspired many including one Sir Arthur Cotton who built a dam in the 19th century straddling the Kollidam, a major tributary of the Cauvery River.

Grand Anicut is about 24 kilometers (15 miles) from main Trichy town, and opens up wonderful views of the Cauvery River and the serene patch of greenery beyond it. Better still, if you can make it at a time when the dam gates are open. Local fishermen throng the area, and cast their nets to make a catch. It is quite engrossing to watch them scramble from one bank to another with their nets in an attempt to get a better catch.

A good stopover and a refreshing break from your temple tour of Trichy!
