Perunthenaruvi Weir is a diversion dam built across Pamba river at villages of Naranammoozhy and Vechoochira in Pathanamthitta District of Kerala, India. Perumthenaruvi Small Hydroelectric Project 6 MW (2×3) is a run-of-the-river scheme in river Pamba, and the weir is a part of this scheme. This envisages the utilization of water from 442 km2 (171 sq mi) catchment of Pamba and Azhutha river for electricity generation under a net head of 18.00 m. The power house is located on the left bank of Pamba river. The weir is a concrete gravity type with a height of 10.93 metres (35.9 ft) and a length of 227.50 metres (746.4 ft). Taluks through which the release flow are Ranni, Konni, Kozhencherry, Thiruvalla, Chengannur, Kuttanadu, Mavelikara and Karthikappally.[1]
