Macfarlane, D.F. 1982 Earnscleugh Flats irrigation, engineering geology of the Clyde dam - Fraser River link race. Lower Hutt: New Zealand Geological Survey. New Zealand Geological Survey report EG 363 14 p.
Abstract: An integral part of the proposed upgrading of the Earnscleugh Flats irrigation system is the supply, by link race, of water from the Clyde Dam reservoir (Lake Dunstan). The water right for the dam requires the delivery of 1 cumec to the Fraser River to provide a minimum residual flow. After considering various options, a preliminary design proposal for the race was prepared by MWD Alexandra (van Barneveld, 1981). This report describes the engineering geology of the proposed link race alignment from the right abutment of the Clyde Dam to the Fraser River.
