The Idukki Dam is built across the river and generates the major chunk of electrical power for the state from its many big and small hydroelectric projects.

Origin and Path

It originates in the Western Ghats range in the Tamil Nadu state. It flows north through Periyar National Park into Periyar Lake, an artificial reservoir created in 1895 by the construction of a dam across the river. The lake has an area of 55 km². Water is diverted from the lake into the Vaigai River of Tamil Nadu via a tunnel through the Western Ghats.
From the lake the river flows northwest through the village of Neeleeswaram to empty into Vembanad Lake on the Arabian Sea coast. Its largest tributaries are the Muthirapuzha River, Mullayar River, Cheruthoni River, Perinjankutti River and the Edamala River.
It is the major water resource for five drought prone districts of Tamil Nadu which includes Theni, Madurai, Ramanathapuram. The dam built across the river is maintained by Tamil Nadu PWD department and it is under the control of Tamil Nadu government for 999 years according to a pact between Kerala, Tamil Nadu governments.
