Ranni-Perinad Weir is a diversion dam built in Kakkad river which is a tributary of Pamba River at Mampara in Ranni-Perinad villages of Pathanamthitta district of Kerala, India.[1] The weir is a concrete-gravity type and is a part of Ranni – Perinad Small Hydro Electric Project, a run off the river scheme in Kakkad river in Pamba basin. It envisages the development of power by utilizing the tail race water from the Maniyar Power house, with installed capacity of 4.0 MW ( 2x 2.0 MW). The release of the water from the dam is to Kakkad river which in turn flows and joins Pamba river and flows through Taluks such as Ranni, Konni, Kozhencherry, Thiruvalla, Chengannur, Kuttanadu, Mavelikara and Karthikappally. [2] The dam is also a part of Ranni-Perinad Water supply scheme.[3]
