Andrews, P.B. 1973 Lake Manapouri: lowered lake levels and possible loss of beach sand and gravel. Lower Hutt: New Zealand Geological Survey. New Zealand Geological Survey report EG 158 4 p.
Abstract: This report comments on shoreline changes at Lake Manapouri that apparently result from lowering the lake level significantly below its natural level. Two reports by Mr I.C. McKellar (16 November, 1972; 2 May, 1973) were examined, particular attention being paid to the accompanying photographic record of shoreline features evident when the lake level was lowered. (auth)
