A. R. Kings ford (photos). to that of the floor of the Cobb Valley is reached and it is from here that a tunnel, some 8184ft long is being driven through the mountain to the floor of the Cobb Valley on the other side where the dam will be built. There is, however, a further 800ft of tramline to the top of the mountain to a level road, which has been formed, about a mile and a-half in length to a point overlooking the Cobb Valley near where the photograph on the left was taken. This extension beyond the tunnel is necessary to give access to the dam for it must be borne in mind that many thousands of tons of material will be needed in its construction. The picture on the left is also of particular interest for it gives some idea of the extent of the storage basin. For the first four miles up from the dam site the river grade is comparatively flat, a dam only 70ft high being sufficient to provide a storage lake of about 340 acres which the engineers state is ample for the generation of 9000 k.w., the proposed initial installation, and by raising the dam 130 feet the storage area can be increased to provide for generation of 30,000 k.w., which is 9000 k.w. greater capacity than Mangahao, which was constructed to supply Wellington city and province and which is now part of the North Island hydro-electric network.
