Sealy Camp, survey party, 1915

Information on page 105 in book “From Bush & Swamp”, reads: Four years passed before another survey party, led by engineer C. Sealy, went into the ranges, where they spent six months of 1915 working in rugged conditions, unseen men toiling in the wilderness, but they emerged with a practicable scheme in mind. They proposed to trap the waters of the Mangahao, which flows from a high gorge to the north, behind two dams and then send the water under two ridges by tunnels, each over a mile long. The water would then drop from a controlling surge chamber through pipelines for 900 feet to a power station at Mangaore. This fall, five times higher than the Niagara Falls, would provide the extreme pressure required at the base of the pipeline to generate the power.
