Johnston, M.R. 1973 Northern Buller power scheme, proposed dam sites, Mokihinui River (S25), preliminary geological inspection. November 1973. Lower Hutt: New Zealand Geological Survey. New Zealand Geological Survey report EG 179 7 p.
Abstract: The northwestern part of the South Island is a high mountainous area known as the Tasman Mountains. The largest rivers draining the western part of the mountains are the Karamea River in the north and the Mokihinui River in the South. Except in their lowest reaches, where they cross relatively small coastal plains, the rivers are confined in narrow, steep walled, rock gorges. The western ends of the gorges are being investigated as possible dam sites for hydro-electric power generation. Two sites are under investigation on the Mokihinui River (grid ref. S25/482973 and S25/493974), and one site is proposed on the Karamea River (S12/677327). At the Mokihinui sites a single dam, about 100 m high, is currently envisaged. Such a dam would create a lake extending up both branches of the Mokihinui River. The Karamea site is reported on separately. (auth)
