Kulamavu Dam is a gravity/brick work dam on the Periyar stream. It is one of the three dams related with the Idukki hydro electric power venture in the Indian territory of Kerala.
Kulamavu Dam is one of the real power ventures working on the River Periyar, the biggest stream in Kerala. The venture is financed by the Government of Canada and is upheld by the waters of the Cheruthoni and Idukki dams.
The water of the dam is coordinated through a power burrow that keeps running on two underground weight shafts. In the wake of going through these poles, the water achieves an underground power station that is situated in the Muvattupuzha Valley.
