A survey of Lake Roxburgh, a recent hydro-electric dam
- Department of Zoology, University of Otago
This survey was carried out for the Otago Acclimatisation Society which was considering the introduction of the Mackinaw Char or Lake Trout (Salvelinus namaycush).
As the lake was formed by the impoundment of the Clutha River in July, 1956 it was 51 years old when the data were collected in January, 1962, and is still undergoing fairly rapid development. A description of the lake at this stage may be of value as a basis for study of its later development and for comparison with other similar dams such as the Waitaki and Benmore dams on the Waitaki River.
