| Kallarkutty dam is a part of Neriamangalam Hydro Electric Project and is located at Kallarktty. The reservoir of the Neriamangalam Hydro Electric Project is created by constructing a dam at Kallarkutty across Mudirapuzha river. The dam is constructed to the downstream of tail race confluences of Sengulam and Panniyar Power stations. The tail water of upstream projects viz. Pallivasal, Sengulam and Panniyar power stations flows to this reservoir. This reservoir is at the tail end of the Mudirapuzha basin. The spill from upstream reservoirs Kundala, Maduppetty, RA Head works, Anayirankal, Ponmudi and Sengulam also reaches this reservoir. The water from Kallarkutty reservoir is diverted through a water conductor system to the Powerhouse of Neriyamangalam HEP located on the right bank of Periyar river. After generating power, the water is released to Periyar river. |
