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.[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 Шаблон:Convert and length of Шаблон:Convert.

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 namely, a) Kosani ( Earth fill dam) 13.8 m high b) Near Kottagiri ( Earth fill dam) 11.0 m high c) Kottagiri ( Earth fill dam) 14.5 m high d) Kuttiyadi ( Concrete dam) 16.5 m high e) Nayanmoola ( Earth fill dam) 3.5 m high f)   Manjoora ( Earth fill dam) 4.0 m high. 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. The water spread area at FRL / MWL is 12.77 km2. The catchment area of Banasurasagar Dam is 61.44 km2. [5]

Шаблон:Main Kuttiady Augmentation Spillway dam is a concrete dam with spillways for the Banasurasagar (kutyadi Augmentation) reservoir. The Spillway dam is part of the Kuttiyadi Augmentation Scheme which is located in Wayanad district. It aims at utilizing 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 and a concrete gravity spillway dam and six saddle dams.Шаблон:Cn

Reservoir

Kutyadi Reservoir layout

The Gross Storage of Kuttiyadi Augmentation (Banasura sagar) Reservoir is 209 Mm3 and live storage 185 Mm3. The water stored in the reservoir is diverted to the reservoir of Kuttiyadi Hydro Electric Project through an interconnecting tunnel. The sill level of diversion tunnel at inlet is 750.83 m. The size and shape of tunnel is varying. It is varying from 2.35 m dia. circular lined tunnel for a length of 890m &2.85 m D-shaped unlined tunnel for a length of 3873 m. Maximum diversion is11.6 m3/s. The diverted water is used for power generation from Kuttiyadi Power Station. FRL of the reservoir is 775.60 m. Top level of dam is 778.50 m. There are four radial gates, each of size 10.97 m x 9.20 m. Crest level of spillway is 767.00 m. Spillway capacity is 1664 m3/s. One lower level outlet is provided in the spillway structure at750.75 m of size 1.10 m X 1.75 m to release irrigation requirement.Шаблон:Cn
