The dam is an earth-fill structure, meaning it is constructed primarily of compacted soil rather than concrete.
It was commissioned during the Third Five-Year Plan of India to boost local agricultural productivity.
The reservoir acts as a crucial water catchment area that supports the biodiversity of the nearby Western Ghats corridor.
The project includes a canal network extending over 35 kilometers to distribute water to Alathur and surrounding regions.
Mangalam Dam is an earth dam constructed across the Cherukunnu River, a tributary of the Mangalam River, in the Palakkad district of Kerala. Completed in 1966, the primary purpose of the dam is irrigation for the surrounding agricultural lands in the Alathur taluk. The structure features a length of 523 meters and a height of 22.86 meters. It sits at the foot of the Western Ghats, creating a reservoir surrounded by forested hills. The site includes an integrated garden and park area managed by the Kerala Irrigation Department for public access. The dam serves as the source for the Mangalam irrigation project, which provides water to thousands of hectares of paddy fields. It is located approximately 50 kilometers from Palakkad town.
The top of the dam embankment provides a panoramic view of the reservoir against the backdrop of the forested Western Ghats.
Bring binoculars as the reservoir attracts various species of migratory birds during the winter months.
Carry your own water and snacks as there are very limited commercial facilities near the dam site.
The area is prone to strong sunlight, so hats and high-SPF sunscreen are recommended.
Do not attempt to swim in the reservoir, as the water depth is inconsistent and the currents near the sluice gates can be hazardous.
Maintain silence, dispose of trash in designated bins to protect the local ecosystem, and do not venture into restricted reservoir zones.
