Abstract: This report presents data from wells (mainly water wells and some foundation test bores) located in coastal South Canterbury and northern North Otago. It covers an area from Washdyke to Oamaru, and inland adjacent to the Waitaki River as far as Omarama, including the Hakataramea Valley (Figs 1 and 2). The reports consists of a table listing well data (Table 1), written logs for those wells from which logs are available (p. 82), graphs of water levels from wells with regular measurements (Fig 3) and a selection of chemical analyses of water samples from wells (Table 2).
