Pothundi Dam is an irrigation dam near a small village in Palakkad district of Kerala state, India. It was constructed in the 19th century. The dam is unusual in being constructed without a conventional concrete core, which is employed in most earth dams to counteract the force exerted by high water pressure. The core is, instead, an unusual mixture of jaggery and quick lime.It is the second dam in Asia constructed without using cement mixture.
The dam is located about 8 km from Nemmara and 42 km from Palakkad. The dam is one of the major water sources for agricultural and drinking in the chittur taluk.
