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:
- Kosani, earth-fill, 13.8 metres (45 ft) high
- Near Kottagiri, earth-fill, 11.0 metres (36.1 ft) high
- Kottagiri, earth-fill, 14.5 metres (48 ft) high
- Kuttiyadi, concrete, 16.5 metres (54 ft) high
- Nayamoola, earth-fill, 3.5 metres (11 ft) high
- Manjoora, earth-fill, 4.0 metres (13.1 ft) high.[1]
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 Lua error in package.lua at line 80: module 'Module:Val/units' not found. . The catchment area of Banasurasagar Dam is Lua error in package.lua at line 80: module 'Module:Val/units' not found..[2]

Reservoir[edit | edit source]
The gross storage of Kuttiyadi Augmentation (Banasura sagar) Reservoir is Lua error in package.lua at line 80: module 'Module:Val/units' not found.; its live storage is Lua error in package.lua at line 80: module 'Module:Val/units' not found.. The water stored in the reservoir is diverted to the reservoir of Kuttiyadi Hydro Electric Project through an interconnecting tunnel. The sill level of the diversion tunnel at inlet is Lua error in package.lua at line 80: module 'Module:Val/units' not found.. The size and shape of the tunnel varies from a 2.35-meter-diameter circular lined tunnel for a length of Lua error in package.lua at line 80: module 'Module:Val/units' not found. to a 2.85-meter D-shaped unlined tunnel for a length of Lua error in package.lua at line 80: module 'Module:Val/units' not found.. The maximum diversion is Lua error in package.lua at line 80: module 'Module:Val/units' not found.. The diverted water is used for power generation from Kuttiyadi Power Station. The FRL of the reservoir is Lua error in package.lua at line 80: module 'Module:Val/units' not found.. The top level of dam is Lua error in package.lua at line 80: module 'Module:Val/units' not found.. There are four radial gates, each of size 10.97 m × 9.20 m. The crest level of the spillway is Lua error in package.lua at line 80: module 'Module:Val/units' not found.. The spillway capacity is Lua error in package.lua at line 80: module 'Module:Val/units' not found.. One lower-level outlet is provided in the spillway structure at Lua error in package.lua at line 80: module 'Module:Val/units' not found. of size 1.10 m × 1.75 m to release irrigation requirement.
