Malampuzha Dam is the largest reservoir in Kerala, located near Palakkad in south India with the scenic hills of the Western Ghats in the background. It is a combination of a masonry dam with a length of 1,849 metres and an earthen dam with a length of 220 metres. The dam is 125 feet high and crosses the Malampuzha River, a tributary of Bharathappuzha, Kerala's second longest river. 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 catchment area is 145 square kilometres, while the reservoir has a capacity of 8000 square meters of water. The canal systems serve to irrigate farm land while the reservoir provides drinking water to Palakkad and surrounding villages.
