Upper moozhiyar dam is an Earthen Dam constructed across Moozhiyar River in Seethathodu village of Pathanamthitta district in Kerala, India. This dam was constructed as a part of Sabarigiri Augmentation Scheme.[1] The stream is located in southern side of Kakki reservoir. It is an embankment structure. [1] Sabarigiri Hydro Electric Project (340 MW) is the second largest hydro electric project of Kerala and is located in Pathanamthitta district. This dam is constructed for diverting the upper reaches of Moozhiyar river, a tributary of Pamba river to the Kakki -Anathode reservoir through a tunnel. The surplus over the storage flows over the rock cut spillway to Moozhiyar river. Taluks through which release flow are Ranni, Konni, Kozhencherry, Thiruvalla, Chengannur, Kuttanadu, Mavelikara, and Karthikappally.[2] Nearest city is Vandiperiyar.[3]
