Cheruthoni is a town on the banks of Cheruthoni River, a major tributary of the Periyar River, the second longest river in Kerala state, India. The area is known by Cheruthoni Dam, which is a part of Idukki reservoir, which provide hydroelectric power to the region.
The town is adjacent to the famous Idukki Arch Dam and the Cheruthoni dam. These dams, along with the Kulamavu Dam, form the Idukki Reservoir. Cheruthoni is part of Vazhathope Panchayat, in the Idukki District. Other villages adjacent to Cheruthoni are Vazhathope, Thadiyampadu, Karimban, Manjappara, Maniyarankudi, Bhoomiyamkulam, Peppara, Manjikkavala and Painavu.
The origins of this place can be traced back to 1940s, following a famine the government allowed farmers to migrate to unoccupied arable lands in the mountains, where they cleared the land for agriculture. Later, this region was identified as an ideal spot for a hydroelectric project. The Hindustan Construction Company was contracted to build the dams on behalf of the Kerala State Electricity Board.
Idukki (ഇടുക്കി), IPA: [iɖukːi], is one of the 14 districts in the Indian state of Kerala. Idukki district lies amid the Cardamom Hills of Western Ghats in Kerala. Idukki district contains two municipal towns - Kattappana and Thodupuzha. The district currently includes five taluks in it.
Painavu is the administrative headquarters of Idukki district of Kerala, India.
Periyar, IPA: [peɾijɐːr], is the longest river and the river with the largest discharge potential in the Indian state of Kerala. It is one of the few perennial rivers in the region and provides drinking water for several major towns. The Periyar is of utmost significance to the economy of Kerala. It generates a significant proportion of Kerala's electrical power via the Idukki Dam and flows along a region of industrial and commercial activity. The river also provides water for irrigation and domestic use throughout its course besides supporting a rich fishery. Due to these reasons, the river has been named the "Lifeline of Kerala". Kochi city, in the vicinity of the river mouth draws its water supply from Aluva, an upstream site sufficiently free of seawater intrusion. Twenty five percent of Kerala's industries are along the banks of river Periyar. These are mostly crowded within a stretch of 5 kilometres (3 mi) in the Eloor-Edayar region (Udhyogamandal), about 10 kilometres (6 mi) north of Kochi harbor.
The Idukki Dam is a double curvature arch dam constructed across the Periyar River in a narrow gorge between two granite hills locally known as Kuravan and Kurathi in Idukki, Kerala, India.
