SA Water will start work on upgrading the Myponga Reservoir’s dam spillway gates later in February.

Access to Reservoir Road, between the Myponga Reservoir Lookout and Forktree Road, has been temporarily closed to safely accommodate work crews and heavy machinery.

SA Water says it has put in place clearly marked detours for pedestrians and vehicles.

The spillway gates operate to safely release water downstream. 

The upgrade is a major project that is expected to be completed by mid-2024.

Myponga Reservoir was officially opened in 1962 after four years of construction.

It was opened to the public for recreational access in 2019.
