Banasura Sagar

Banasura Sagar Dam, which impounds the Karamanathodu tributary of the Kabini River, is part of the Indian Banasurasagar Project consisting of a dam and a canal project started in 1979.The goal of the project is to support the Kakkayam Hydro electric power project and satisfy the demand for irrigation and drinking water in a region known to have water shortages in seasonal dry periods.

In the dam's reservoir there is a set of islands that were formed when the reservoir submerged the surrounding areas.The islands with the Banasura hills in the background provide a spectacular view.It is the largest earth dam in India and the second largest of its kind in Asia. The dam is made up of massive stacks of stones and boulders.
