Tamil Nadu has been primarily an agricultural country. Nowadays, much attention is being given to trace out the glorious past, especially the ancient irrigation management and technology practiced in the state. Limited sources are available to know the best practices of the irrigation system during this period. The Emperors of ancient period not only patronized irrigation but also had given responsibilities to the village institutions for the apt management and appropriate uses of water bodies in the state. The maintenance work called as Kudimaramat system was functioned well. Sluice technology found in Tamil land discloses the scientific advancement of the society then. We could learn the environmental aspects, particularly the knowledge they had given to us for choosing the area of the construction of tanks as well as the materials to be used for long life of the dam without any damage even in natural calamities. Village societies were the authorities of the water rights. However, the changes in landownership pattern and the introduction of canal irrigation paved the way for the decline of tank irrigation in Tamil Nadu. This study made an attempt to highlight the irrigational practices which existed in the ancient Tamil Nadu.
