Hegan, B.D. 1988 Mohaka River power investigations : report on the engineering geological investigations : M55 (Te Hoe) site. [Lower Hutt]: New Zealand Geological Survey. New Zealand Geological Survey report EG 400 43 p.
Abstract: Engineering geological investigations to assess the feasibility of the proposed power development options at the Te Hoe and Mohaka River junction have been completed. While the study has not found any geotechnical features which would preclude the development of the site at M55 some uncertainties exist as to the exact nature of the geological structure, especially on the right abutment and immediately upstream of the dam site. Further investigations are required to clarify the geological structural setting before any detailed abutment investigations are undertaken. Areas requiring further investigations in terms of reservoir stability are identified. Construction materials for a concrete gravity structure are available near the site. (auth)
