The project consists of a series of dams interconnected by tunnels and canals for harnessing the Parambikulam, Aliyar, Nirar, Sholiyar, Thunakadavu, Thekkadi and Palar rivers, lying 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 for picnics. Overnight stay is possible in forest rest houses. A tree-top house provides accomodation for the adventurous.
