Kulamavu Dam (Malayalam: കുളമാവ് അണകെട്ട്) is a gravity/masonry dam on the Periyar river. It is one of the three dams associated with the Idukki hydro electric power project in the Indian state of Kerala. The dam is situated on the Thodupuzha - Puliyanmala state highway (SH-33), about 23 km (14 mi) from Idukki arch dam, 22 km (14 mi) from Cheruthoni dam and 38 km (24 mi) from Thodupuzha.
The dams of Idukki, Cheruthoni and Kulamavu extend to an area of 33 km². The construction of these three dams formed a 60 km² artificial lake. The water stored in it was used for the production of electricity at the power house in Moolamattom.
