Kallarkutty Dam
Kallarkutty Dam is a gravity dam built on the Muthirapuzha river, a tributary of the Periyar river, as part of the Neriamangalam Hydroelectric Project[1] at Kallarkutty in Vellathooval panchayat of Idukki district in Kerala, India. The water discharged from the Chenkulam dam's powerhouse and the Muthirapuzha river is diverted to the Neriamangalam powerhouse near Panamkutty above the Pambla dam. The Hydroelectric Project was commissioned on 27 January 1961 to generate 45 MW of power using 3 turbines with a capacity of 15 MW. In 2006, the project was upgraded from 45 MW to 52.65 MW.[2] Taluks through which release flow are Udumbanchola, Devikulam, Idukki, Kothamangalam, Muvattupuzha, Kunnathunadu, Aluva, Kodungalloor and Paravur.

Reservoir
The Kallarkutty dam is the recipient of flows from both arms of the Muthirapuzha sub-basin.[6] The reservoir thus formed is spread about 0.648 sqkm and has 6.88 million cubic meter capacity.[7] Kallarkutty reservoir hosts Boating and other hydel tourism activities.[8][9]
