The north-west trending section of the Adelaide River Gorge appears to be suitable for a dam site, subject to confirmation by diamond drilling. No further investigation should be done, and no specific recommendations can be made, until a topographic or photogrammetric survey of the catchment area has been completed and an estimate of the optimum height of the dam wall has been made. Alternative dam sites are available if the height of the wall is between 150 feet and 80 feet, or less than 80 feet. These sites have been mapped but no detailed survey has been made of the spillway to be used in conjunction with them. The main problem appears to be the ratio of catchment area to storage area. If a dam is practicable, a provisional site should be selected and cleared and exploratory diamond drilling should be done. A final decision on the dam Site can then be made. There is abundant rock suitable for aggregate and rockfill, but a search for local sources of sand and clay will be necessary.
