The survey was aimed at various aspects of hydrogeology within the Piccadilly Valley and immediate surroundings. The Piccadilly Valley is located 10km South East of Adelaide in the Hundred of Onkaparinga. The extent of the area ranged from 1km west of Summertown to Carey Gully to the east, and north-south from Uraidla to Piccadilly. The main aspects in the survey were trying to relate yields from irrigation bores with both the geology and land use in the area. Following a period of field survey work involving bore location, water sample collection, and standing water level measurement, comparisons with previously recorded information were made. In interpreting the results of the comparisons, direct correlations between the geology, topography, yields from bores and land use are apparent. Few general conclusions can be made to the lack of regularly recorded information in the past.
