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