'''Anayirangal Dam''' is an [[Earth fill dam|earthen dam]] built on the [[Panniyar River|Panniyar river]] in [[Chinnakanal]] and [[Santhanpara]] panchayats, {{Cvt|22|km}} from [[Munnar]] in [[Idukki district]] of [[Kerala]], India.<ref>{{Cite web|title=Anayirankal Dam – KSEB Limited Dam Safety Organisation|url=https://dams.kseb.in/?p=147|access-date=2021-07-07|language=en-US}}</ref>
The dam is surrounded on one side by forest and on the other by Tata Tea Plantation. The dam is located near the [[State Highway 19 (Kerala)|Munnar - Kumily road]]. The water flowing from the dam reaches Kuthungal and [[Ponmudi Dam|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 {{Convert|34.14|m}} and Length is {{Convert|326.13|m}}. The reservoir usually fills up in June and July.<ref>{{Cite web|title=പ്രളയത്തിലും നിറയാതെ ഇടുക്കിയിലെ ആനയിറങ്കൽ ഡാം|url=https://www.asianetnews.com/news/annayirankal-dam-at-idukki-peka5q|access-date=2021-07-07|website=Asianet News Network Pvt Ltd|language=ml}}</ref>

The project is situated in Muthirapuzha basin, a sub basin of [[Periyar (river)|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 [[Udumbanchola|Udumpanchola]], [[Devikulam taluk|Devikulam]], [[Kothamangalam]], [[Muvattupuzha Taluk|Muvattupuzha]], [[Kunnathunad]]u, [[Aluva]], [[Kodungallur|Kodungalloor]], [[Paravur Taluk|Paravur]].<ref>{{cite news |last1=Wilson |first1=James |title=Understanding the 42-year-old Idukki dam which is now saving Kerala |url= https://theprint.in/opinion/in-monsoon-battered-kerala-idukki-dam-has-stood-tall-to-prevent-floods/97579/ |publisher=The Print |date=13 August 2018}}</ref>
