Anathode is a stream which joins Kakki river downstream of Kakki dam before the confluence with Pamba river. The dam makes a common reservoir with Kakki. The spillway for the reservoir complex is located by the side of Anathode Flanking Dam. The reservoirs formed by the two dams are connected through the natural valley.[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]
