This project consists of a series of dams interconnected by tunnels and canals for harnessing the waters of the Parambikulam, Aliyar, Sholiyar, Thunakadavu, Thekkadi and Palar rivers, flowing at various elevations, for irrigation and power generation. The scheme is an outstanding example of engineering skill. It is located in Anamalai range and is ideal as a picnic spot. Overnight stay is possible in the forest rest house. A treetop house provides accommodation for the adventurous.
