Farm ponds are constructed by Agricultural Engineering Department (AED) to harvest rain water from smaller catchments of about 2 to 5 hectares which form the land holding of a single farmer and provide supplemental irrigation at critical stages of crop growth mainly as a "lifesaving irrigation' to save the crop without wilting. Since the farm pond is constructed in farmer's land, the conveyance loss is minimized. Under suitable conditions, whenever the water can be stored for more than 4 months, fish culture can be encouraged to get additional income. It is proposed to construct 521 farm ponds in the Phase-I and of it 80 percent are proposed in the Cauvery & North Eastern Zones. AED has proposed to execute 2800 farm ponds in TNIAM Project in the total project period.
