Lake Karapiro
Lake Karapiro (Māori: Karāpiro) is an artificial reservoir lake on the Waikato River at Karapiro, 8 kilometres (5.0 mi) south-east of Cambridge in New Zealand's North Island. The lake was formed in 1947 by the damming of the Waikato River to store water for the 96-megawatt Karapiro power station.
