Manjoora Saddle Dam

Manjoora Saddle dam (Malayalam:മാഞ്ഞൂര തടയണ) is an earthen dam constructed across Karamanthode, which is a tributary of Kabani River in Padinjarathara Panjayath of Wayanad district in Kerala, India. It is one of the six saddle dams of Banasura sagar reservoir built as oart of the Kuttiyadi Augmentation scheme.

The Kuttiyadi Augmentation Scheme comprises 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. The water spread area at FRL / MWL is . The catchment area of Banasurasagar Dam is .
