A flood control dam on Glen Osmond Creek in Ridge Park Reserve, Myrtle Bank, has been constructed to reduce peak stormwater flow in Glen Osmond Creek, and reduce the risk of flooding in downstream areas along Glen Osmond and Keswick Creeks.

Commissioned in July 2015, the Ridge Park flood control dam also collects stormwater for the City of Unley’s managed aquifer recovery (MAR) scheme. Under the MAR, harvested stormwater is stored in an underground aquifer for irrigation of Unley’s parks during periods of dry weather.

The Ridge Park flood control dam is outlined in Section 10.6 of the 2016 Stormwater Management Plan.
