Idamalayar Dam

The Idamalayar Dam is a hydroelectric power station on the Idamalayar River in Kerala that rises 102 meters above the river, spanning 373 meters across. The facility uses two turbines to generate electricity for the region.

Construction began in 1970 and took 17 years, with administrative challenges and labor issues affecting progress. Its completion marked a turning point in hydroelectric development for the region.

The reservoir provides habitat for various bird species, including the Malabar grey hornbill that makes its home in the region. These animals use the water and surrounding areas as an important refuge.

The site is located in the Anamalais region and can be viewed from various vantage points to understand its structure and operation. Access is best by road through the surrounding areas, though conditions can be slippery during the rainy season.

The reservoir behind the dam spreads across about 28 square kilometers and supplies water not only for power generation but also for many farmlands. This dual system shows how the facility works far beyond its original purpose for the local economy.
