context_page_description: Idamalayar Dam is a multipurpose concrete gravity dam located at Ennakal, Ernakulam.
  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, the dam created a multipurpose reservoir covering 28.3 km² 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 generation requirements. The dam will benefit the Idamalayar Irrigation Development Project by diverting water released from the tail race channel of the Idamalayar power station.
context_section_description: The Idamalayar Dam is located on the Idamalayar River, a tributary of the Periyar River in Kerala. Edamalayar originates in the Anamala Hills at elevation of 2,520 metres (8,270 ft). The river is a perennial source draining a catchment area of 381 km² (147 sq mi) with a topography of high relief. The catchment receives annual rainfall of 6,000 millimetres (240 in), 90% of which occurs during the monsoon months of June to September.
  The dam is located 81 kilometres (50 mi) from Ernakulam in Ernakulam district and 10–12 kilometres (6.2–7.5 mi) from the Bhoothathankettu dam (literal meaning in Malayalam language: "monster dam") on the Periyar River, which takes its name from local myths attributing its construction to demons who built it with the intention of submerging Thrikkariyoor temple.
