. The Azhutha Dam was constructed as an augmentation dam for the Idukki Hydro Electric Project. Construction of the project started in 1987 and was expected to be commissioned in 1991, but the project overrun and was only partially commissioned in June 1998. The year of completion was 2007. The release of the water from the dam is to Azhutha river and it flows through Ranni and Ayroor taluks. This project diverts waters from the 16.8389 km² catchment of the Azhutha river, a tributary of Pamba river to Idukki reservoir and thereby increasing the power potential of Idukki Hydro electric Project by 57 MU.
