Solution:

• 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.
• The dam is also known as Kuttiyadi Augmentation Main Earthen Dam. The dam has a height of 38.5 metres (126 ft) and length of 685 metres (2,247 ft).
• 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 are in the background view.
