In 2024, together with major construction partner John Holland Guidera O’Connor Joint Venture, we began remediation works to the spillway gates and associated infrastructure. This was the first time since the spillway gates were commissioned in 1962 that they had been removed. These works ensure they will continue operating reliably into the future.
This project is complete.
Myponga Reservoir, nestled near the township of Myponga, is a critical piece of SA Water’s infrastructure, supplying safe, clean drinking water to the majority of Adelaide’s south.
The reservoir was built between 1958 and 1962, at a time of rapid economic expansion in South Australia.
Its construction increased the state’s storage capacity, supporting population growth and the expansion of industry in Adelaide’s south.
Its capacity is managed via the Myponga spillway gates. When a rainfall event exceeds the dam’s capacity, water is released via the spillway gates into the Myponga River.
Water from the reservoir is treated at the nearby Myponga Water Treatment Plant before it is supplied to homes, businesses, schools and hospitals on the Fleurieu Peninsula.
The broader Myponga Reservoir Reserve is open to the public for recreational use, including fishing (with PIRSA permit), kayaking and canoeing.
