The Panniyar River is a tributary of the Periyar River, which is the longest river in Idukki District of Kerala, India. [1] The tributaries of the Panniyar River are the Uchilkuthipuzha, Mathikettan Puzha, Chemmannar and Nander Puzha, which originate from the hills of Matikettan National Park. [2] Ponmudi dam is built across the river as a part of Panniyar Hydroelectric project. [3] After generating power, the water is released to Panniyar river itself. The tailwater from the Panniyar powerhouse and the spill from Ponmudi dam reach the Kallarkutty dam. [4] It then flows through Udumbanchola, Devikulam, Kothamangalam, Muvattupuzha, Kunnathunadu, Aluva, Kodungallur and Paravur. Panniyar is the source of drinking water for Rajakumari, Rajakkad, Shanthanpara and Senapati in Idukki district. [5] [6]
