Kulamavu Dam

Kulamavu Dam is a gravity/masonry dam built across the Kilivillithode River, a tributary of the Periyar River in Idukki District, Kerala. Completed in 1977, it forms part of the Idukki Hydro Electric Project along with Idukki Arch Dam and Cheruthoni Dam, creating an artificial reservoir spanning approximately 60 square kilometers. The dam diverts water through a power tunnel to an underground powerhouse at Moolamattom with an installed capacity of 780 MW.

Visitors can expect scenic views of the dam structure and surrounding lush green hills from designated viewpoints. The area serves as a picnic spot with opportunities for bird watching, where species like snake birds and kingfishers are frequently spotted. Photography is not permitted at the dam site, and vehicles cannot be parked near the dam structure. Visitors access viewing areas on foot from parking locations further away.

Kulamavu Dam was completed in 1977 as part of the Idukki Hydro Electric Project. Construction began on April 30, 1969. The dam, along with Idukki Arch Dam and Cheruthoni Dam, creates the Idukki Reservoir which diverts water through a 2027-meter long power tunnel to an underground powerhouse at Moolamattom with 780 MW capacity.
