Anathode Dam is a flanking dam of masonry gravity type situated in Sethathode panchayath of Seethathode village in Pathanamthitta district of Kerala, India. This dam is constructed on Anathode river which is a tributary of Pamba river.[1]

Anathode is a stream which joins Kakki river downstream of Kakki dam before the confluence with Pamba river. Anathode Dam and the nearby Kakki Dam form a common reservoir, as they are connected through a natural valley. Both dams were built as part of the Sabarigiri Hydro Electric Project. The spillway for the reservoir complex is located by the side of Anathode Flanking Dam. [2] Kakki & Anathode dams are about 4 kilometers apart by road. Taluks through which release flows are Ranni, Konni, Kozhencherry, Thiruvalla, Chengannur, Kuttanadu, Mavelikara and Karthikappally.[3]
