The Kangaroo Creek Dam is located in the River Torrens Gorge, 14 miles north-east of Adelaide. (Fig.1.). The dam has been constructed as part of the metropolitan water supply scheme, to store water pumped from the River Murray via the Mannum-Adelaide Pipeline, as well as increasing the annual yield of the River Torrens through 112 square miles of catchment area. At full supply level (800 feet above sea level) the reservoir will contain 6000 million gallons of water. The Kangaroo Creek Dam Project included a 200 ft. high rockfill dam and an 840 ft. long spillway, constructed by private contractors on behalf of the Engineering and Water Supply Department.
