Banasura Sagar Dam, situated in Padinjarathara in Kerala is the largest earth dam in India and second largest dam in Asia. Banasura Dam is under the control of Padinjarathara KSEB Station. India's first operating floating solar power plant was established in Banasura Dam. The dam is surrounded by Banasura Hills. Dam 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.[1] 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 776 metres (2,546 ft).

In the dam's reservoir there is a set of islands that were formed when the reservoir submerged the surrounding areas.[2] The islands with the Banasura hills are in the background view.[3] 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.[4]

The Kuttiyadi Augmentation Scheme consists of a main dam known as Banasurasagar Dam, an earth fill dam and a concrete gravity spillway dam and six saddle dams:

All the dams, except Kuttiady saddle, are earth-fill dams. The Kuttiyadi saddle dam is a concrete dam. The spillway is located adjacent to the main dam at the right bank of the original river course.

Location[edit | edit source]

The Banasura Sagar Dam is located 2 km from Padinjarathara and 20 km from Kalpetta in Wayanad District of Kerala in the Western Ghats of India. It is the largest earthen dam in India and the second largest in Asia[4] and a starting point for hikes into the surrounding mountains.[6] It is an important tourist attraction.[7] Banasura Sagar Dam is at the foot of the Banasura Hill.

Spillway Dam[edit | edit source]

Spill way dam of Banasura sagar dam

Kuttiady Augmentation Spillway dam is a concrete dam with spillways for the Banasurasagar reservoir. The spillway dam is part of the Kuttiyadi Augmentation Scheme, which is located in Wayanad district. It aims at using water of the Karamanthodu River, a tributary of Kabani River. The Scheme consists of a main dam known as Banasurasagar Dam, an earth-fill dam, a concrete gravity spillway dam, and six saddle dams.[citation needed]

Reservoir[edit | edit source]

Etymology[edit | edit source]

The Banasura Sagar Dam is named after Banasura, the son of Mahabali who as per local Hindu mythological belief was a very respected king of Kerala.[citation needed]

Tourism[edit | edit source]

The dam has become a popular tourist destination. Many people visit the place to go trekking at the Banasura Hill and speed boating at Banasura Sagar Dam. The Banasura Hill Resort, located about 20 km from the dam was rated as Asia's largest Earthen Resort by BBC.[citation needed]
