Manton Dam

The Manton Dam is a decommissioned small concrete arch dam across the Manton River, located approximately 70 km (43 mi) south of Darwin, in the Northern Territory of Australia. The dam was originally constructed by the Department of Defence during World War II to provide a reliable supply of potable water to Darwin, completed in 1942. Decommissioned following the construction of the much larger Darwin River Dam in 1972, the resultant reservoir of the Manton Dam is now mostly used for recreation, such as fishing, boating and water skiing, surrounded by a conservation area for native flora and fauna.
