Anayirankal dam is a part of Panniyar Hydro Electric Project and is located in Idukki District of Kerala State. The project is in Mudirapuzha basin, a sub basin of Periyar River basin. The reservoir is created by constructing a dam at Anayirankal. The dam is provided with ungated spill way. The water stored in the reservoir is released to the river downstream through an outlet arrangement. This water is diverted by an overflow weir at Kuthungal to Kuthungal Power House. After generation of power the water is released to Ponmudi reservoir at the downstream. The water from the Ponmudi reservoir is diverted to Panniyar Power station (30 MW) located on the left bank of Mudirapuzha and released back to Mudirapuzha.
