The Thattekkad Bird Sanctuary, covering an area of barely 25 km², and located about 60 km north-east of Kochi (Kerala state, India), was the first bird sanctuary in Kerala. Salim Ali, one of the best known ornithologist described this sanctuary as the richest bird habitat on peninsular India. Thattekkad literally means flat forest, and the region is an evergreen low-land forest located between the branches ofPeriyar River, the longest river in Kerala.

Bhoothathankettu is a dam and tourist spot in Kerala, India. It is situated outside the village of Pindimana, about 10 km away from the town of Kothamangalam and 50 km away from the main city of Kochi. The original natural dam has been supplemented by a modern dam impounding the Bhoothathankettu Reservoir (Thattekad Reservoir). During the Malayatoor pilgrim season, travelers use the roads through the forest

The Idamalayar Dam ( ഇടമലയാർ അണക്കെട്ട്) is a multipurpose concrete gravity dam located at Ennakal, near Bhoothathankettu, on the Idamalayar River, a tributary of the Periyar River in Kerala, South India. Completed in 1985, with a length of 373 metres (1,224 ft), the dam created a multipurpose reservoir covering 28.3 km² (10.9 sq mi) in the scenic hills of the Western Ghats.

The reservoir storage is utilized by a hydroelectric power station which has an installed capacity of 75 MW with two units of 37.5 MW capacity, producing an annual energy output of 380 GW·h.

The large reservoir created by the Idamalayar Dam is operated by the Kerala State Electricity Board to augment its peak power generationrequirements. The dam will benefit the Idamalayar Irrigation Development Project by diverting water released from the tail race channel of the Idamalayar power station.
