The Kallanai Dam was “[built] during the second century AD by Karikalan, a king of southern India's old Chola Dynasty” and “is also one of the oldest irrigation systems in the world that is still in use” (Agoramoorthy and Hsu, 2008). “The purpose of the dam was to divert the waters of the Kaveri across the fertile Thanjavur delta region for irrigation via canals. Since the English arrived in the eighteenth century, the Kallanai has been tampered with and other hydraulic structures have been added nearby. It is therefore difficult to extrapolate from the current situation into the past to understand the workings of the anicut”

The Kallanai was built to divert floods from the Kaveri branch of the river into the Kollidam branch “via a short connecting stream” “when the water level in the river rose above its crest” (Bijker, 2007). The Kollidam “was the wider (also the steeper, straighter, and hence faster) of the two [river] branches, and…the flood carrier. It was barely used for irrigation. Almost all of the 600,000 acres irrigated by the river in 1800 were delta lands south of the Kaveri branch. So the Kaveri branch was the lifeline for delta farmers, while the Kollidam was of little consequence for them” (Bijker, 2007). Once the floods were diverted to the Kollidam, they “[flowed] directly to the sea, causing minimal damage to agriculture”
