Pimpama Estuary |
|
|
|
- Consistently elevated nutrient levels but improved dissolved oxygen levels above the weir
- Lower freshwater inputs from the catchment resulting in very much higher salinity levels above the weir compared to 2006
- Extensive intact natural riparian habitat in the inter-tidal zone with impacted background habitat in the reaches above the weir

Coomera Estuary |
|
|
|
- Generally good water quality, but more stringent water quality guidelines lead to non-compliance from some indicators
- Heavily impacted riparian habitat throughout the estuary, particularly on the southern banks
