There is a network of two canal systems that serve the dam's reservoir of 42,090 hectares. The dam project was begun in 1949 and completed in 1955. The total catchments area is 145 square kilometres, while the reservoir has a capacity of 8000 square meters of water. It is also the biggest irrigation project in Kerala with a large network of canal systems. 

Purpose: The canal systems serve to irrigate farm land while the reservoir provides drinking water to Palakkad and surrounding villages. malampuzha Dam has brought prosperity to the district, making Palakkad the `rice bowl of Kerala'. Paddy is cultivated in 50,000 acres (200 km2) in two seasons each using waters from the malampuzha dam. The water from the dam is also utilized for mini hydroelectric project. The dam was conceived as a multi-purpose project to provide water for irrigation, drinking, industries, power generation, fish farming and water transport

Location: The Pothundi Dam is located in Chittur taluk, about and 42 km from Palakkad; around 17 km away from Nelliampathi, and 8 km from Nemmara. 

Impounds: Pothundi is the oldest dams of State of Kerala which was constructed in the 19th century. . 

Significance: It is the second dam in Asia constructed without using cement mixture. 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. The strength of the Pothundy dam is one of the wonders for the present technology. The Pothundy dam is a nice site for tourists, covered with mountains.The well known Nemmara Vallengi Vela festival is organised in the banks of this dam where people visit in large number. 

Purpose: The Pothundi dam was constructed with a main aim of providing water for irrigation to Pallakad district in Kerala. The dam is one of the major water sources for agricultural and drinking in the chittur taluk.
