A detailed look at the site of the Manapouri power scheme.

'Brief outline of a great enterprise, The New Zealand Sounds Hydro-electric Concessions Limited'.
'Manapouri - Deep Cove Hydro-Electric Power Scheme aggregating 300,000 horse-power. The largest water-power proposition in the Southern Hemisphere'.
'On the South West coast of the South Island of New Zealand extending for 150 miles, are situated Fiords or Sounds of unrivalled beauty which, in the case of Doubtful Inlet, penetrate inland to a distance of up to 25 miles'.
'This sound provides a magnificent harbour surrounded by mountains averaging a mile high. The depth of water ranges from 200 ft. to 1500 ft. - approximating about twice the depth of the ocean outside Deep Cove area marked U'.
'Here on these high mountains the rainfall is from 150 to 250 inches per year. Great waterfalls drop thousands of feet sheer into the waters of the sound'.
'It is predicted that the water powers of this rugged country will produce more wealth per acre than the fertile lands of our best dairying districts'.
'From snow-line to waters edge dense Beech (Nothofagus) Forests clothe the mountain sides'.
'In December 1925 a party of 8 explorers led by Messrs J. Orchiston and A. Leigh Hunt (two members of the syndicate) journeyed to Deep Cove via Lake Manapouri'.

'There will be established on Deep Cove Flat, Hydro-Electric works generating 300,000 horse power, producing electricity at the lowest unit cost in the world with which Nitrogen will be extracted from the air providing the most valuable fertiliser, Nitrate Of Lime, thus enabling many parts of the British Empire to largely increase their productivity'.
