Whakamaru Power Station is a hydroelectric power station on the Waikato River, in the North Island of New Zealand. It was the fourth hydroelectric power station on the Waikato River to be installed. Whakamaru is one of the larger generating stations operating on the Waikato river. It is currently operated by state-owned electricity generator Mighty River Power. The adjacent Whakamaru switching station is operated by Transpower and is an important node on the national grid. ==History== Development work started in 1949 with the construction on of road from Mangakino which at the time was the operational centre of the Waikato hydroelectric scheme. Firstly a diversion channel long, deep and wide was built taking 3 years to complete. The foundation rock turned out to be deeply cracked and filled with clays rendering it partially porous. Shafts were sunk into the rock and this allowed the clay to be cleared and cement grout was later forced into the rock which was then back-filled with concrete. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Whakamaru Dam」の詳細全文を読む スポンサード リンク
