Anayirangal Dam is an earthen dam built on the Panniyar river in Chinnakanal and Santhanpara panchayats, from Munnar in Idukki district of Kerala, India.[1] The dam is surrounded on one side by forest and on the other by Tata Tea Plantation. The dam is located near the Munnar - Kumily road. The water flowing from the dam reaches Kuthungal and Ponmudi dams through the Panniyar river. Power is generated at Kuthungal and Panniyar powerhouses. The dam stores water from small streams flowing from Bealram and rainwater flowing from the hills on the Tamil Nadu border. The height of the dam is and Length is . The reservoir usually fills up in June and July.[2]
The project is situated in Muthirapuzha basin, a sub basin of Periyar River. The reservoir is created by constructing a dam at Anayirankal. Construction was led by E.U.Philipose, Superintending Engineer, Kerala State Electricity Board. The dam has ungated spill way system. The water stored in the reservoir is released to the river downstream through an outlet. This water is diverted by an overflow barrage at Kuthungal to Kuthungal Power House. After generation of power the water is released to Ponmudi reservoir at the downstream. This water is then diverted to Panniyar Power station located on the left bank of Muthirapuzha and released back to Muthirapuzha River and flows downstream to Kallarkutty reservoir.From there, the river flows through taluks of Udumpanchola, Devikulam, Kothamangalam, Muvattupuzha, Kunnathunadu, Aluva, Kodungalloor, Paravur.[3]
Reservoir is formed by impounding the Panniyar river. There is a second reservoir made by Ponmudi dam which is part of the Panniyar project.
Panniyar Power House in Vellathooval village, Konnathadi Grama Panchayat, on the left bank of Muthirapuzha, generates 30 MW of electricity using 2 turbines of 15 MW each. Annual production is 158 MU. In 2003, the project was upgraded from 30 MW to 32.4 MW.[4]
