Summary: Water quality in this sub-catchment is not able to be assessed due to a paucity of information. However, this is the smallest sub-catchment in the catchment and its contribution to the overall water quality is small.
Issues: The catchment is largely special uses which is UTS Ku-ring-gai.
Knowledge Gaps: No sewerage information is known for the catchment.
Recommendations: Knowledge of this sub-catchment is minimal and additional information about the sewerage system is required. There are also fertilised playing fields within the catchment which may bear some investigation. However, the small size of the catchment makes the gathering of this information a low priority.
