The Idukki Dam stands between the two mountains Kuravanmala and Kurathimla,839 metres high and 925 metres high respectively. The dam is situated near the Cheruthoni Barrage, with the Kulamavu Dam to its west. These three together extend between rocky hills to form the largest reservoir in Kerala. Idukki District is known for its dam and also for being Kerala’s forest district with an astonishing 50 percent of its total area under green cover. Idukki Dam is the world’s second and Asia’s first arch dam. This reservoir and the famous Idukki Wildlife Sanctuary are located 50 kms from the Periyar Tiger Reserve.

Any work done on possibilities of developing fresh water fisheries potential within this reservoir?
Hi Eldo, The local tribal community has defined extraction rights for personal consumption and small scale sales. Fisheries might throw off the balance of bird and animal populations that feed off the current reservoir fish population. Interesting question though!
