Infrastructure

The Patawalonga Lake system – locally nicknamed “The Pat” – is an artificial lagoon managed by the state government, and plays an important role in local flood prevention, stormwater management, and marine ecology.

Our beach and coastline are important council assets enjoyed and used by many residents and visitors. Polluted stormwater however can quickly ruin the appeal of our beaches and have long-term negative impacts on our marine environment. You can find the Stormwater drain application here.

This map was developed in 2013 for the City of Marion and City of Holdfast Bay joint Stormwater Management Plan. The data contained on this map is based on survey, hydraulic and hydrological modelling at accuracies sufficient for broad scale flood risk management and planning only.
