The 62-year-old Veedur Dam (click the link to see the dam post) irrigates about 2,200 acres in Tamil Nadu and 1000 acres in Puducherry is classified as a minor irrigation project in India. A project designed to irrigate an area of 2000 hectares or less are classified as minor irrigation since India adopted the command area-based system of classification.
Irrigation in India is a network of major and minor canals from Indian rivers, even though groundwater irrigation covers 65% of irrigation in India. 2/3rd of the cultivated land is dependent on monsoons, which is most of the time unreliable and unpredictable.
The Veedur dam is a major source of irrigation for over 100 villages in Villupuram and the state of Puducherry, through its prime channel and five branch canals for about 17.6 km. And what you see in the images is the Intake Tower in yellow (which drew water to the canal) and a pretty blue and white-colored staircase leading to the same. Since I focused on the left side of the dam, I could capture the open canal on the other side of the road.
