About the Myponga Reservoir
Myponga is a concrete arch dam with a ski-jump spillway which was a four-year project completed in 1962.
There was a lucky escape for one workman during the construction of the pipeline from the dam. The man was working inside the pipe about 150m downstream of the dam when he and the pipe were buried by a rockslide. When the debris was cleared away the worker was found unhurt.
Prior to the construction of the Myponga Water Treatment Plant in 1993 water from Myponga was used to supplement the Happy Valley Reservoir.
