Kangaroo Creek Reservoir is a 19,160 megalitre artificial water storage reservoir in the Adelaide Hills, South Australia. It was built from 1966 to 1969, by damming the River Torrens west of Cudlee Creek. The stored water is used to maintain the Hope Valley Reservoir's level via discharge through the Torrens. Water is held back by a 131 metres (430 ft) long, 65 m (213 ft) high concrete clad, rock filled dam wall. It is named after Kangaroo Creek, a tributary of the Torrens with a 18 km2 (7 sq mi) drainage basin, which enters the reservoir on its southern side.
