Vadakkepuzha Weir (Malayalam:വടക്കേപ്പുഴ തടയണ) is a diversion dam of Earthen type constructed across Vadakkepuzha which is a tributary of Muvattupuzha river in Arakkulam village in Idukki district of Kerala, India. Vadakkepuzha weir is a part of an augmentation scheme for the Idukki Hydro Electric Project. Narakakkanam, Azhutha, Vazhikkadavu, Vadakkepuzha and Kuttiar diversion schemes were later added to Idukki HEP to augment the reservoir. Water from the reservoir is pumped in to Idukki reservoir through a pump house with three pumps.
