by temporary syphons to enable the construction of the headworks and make sealing of the natural dam easier. Power stations Although the Waikaretaheke River carries a flow of about 17 m³/s from Lake Waikaremoana, the head of water through the 3 power stations, Kaitawa, Tuai, and Piripaua is around 450 metres, allowing the stations to potentially generate 138 megawatts all up. The 250m head of water for the Kaitawa station is the highest for a power station in New Zealand and among the highest in the world.
