2023 annual Curdies water quality report provides a summary of Curdies EstuaryWatch and WaterWatch monitoring activities. 

The purpose of this annual report is to share information about the baseline and ongoing monitoring occurring in the Curdies catchment by Corangamite CMA citizen scientists with Curdies River Coordinating Committee.  

The report provides information on community participation in EstuaryWatch and WaterWatch programs and community engagement opportunities aligned with on-ground works.

Data summary for Curdies estuary 

• Dissolved oxygen measured at the surface was fair at Dorey St pontoon (Cu1) and Boggy Creek (Cu2). In previous years it has been fair at both. 

• Dissolved oxygen measured at the bottom was fair at Dorey St pontoon (Cu1) and good at Boggy Creek (Cu2). In previous years it has been excellent at both. 

• Turbidity was fair at Dorey St pontoon (Cu1) and fair at Boggy Creek (Cu2). In previous years it has been fair at Cu1 and excellent at Cu2. 

• pH at Dorey St pontoon (Cu1) and Boggy Creek (Cu2) was fair at both sites. This is consistent with fair condition at both sites in previous years. 

• Reactive phosphorus was good at Dorey St pontoon (Cu1) and poor at Boggy Creek (Cu2). This parameter has not been monitored previously. 

Data summary for Curdies freshwater reaches 

• Electrical conductivity was good at all monitoring sites in the catchment. 

• Dissolved oxygen was highest in upper reaches of Scotts Creek. Poor oxygen levels in Cooriemungle Creek will impact Scotts Creek below the confluence as evident in fair levels seen in lower reaches of Scotts Creek. 

• Turbidity was rated good at all monitoring sites in the catchment. 

• pH was good at all monitoring sites in the catchment. 

• Reactive phosphorus was rated poor at all sites
