Summary: Water quality in this sub-catchment is unknown because no water quality sampling has taken place.
Issues: The sub-catchment has high residential landuse and it is suspected will have the same overflow problems and exfiltration problems as other areas of Lane Cove Council since it is of comparable age.
Knowledge Gaps: No sewerage information is known for this sub-catchment and stormwater information is scant. No water quality data has been collected for this sub-catchment.
Recommendations: More information regarding the status of the sewage system should be found for this sub-catchment because this area contains high density housing and is likely to have sewer overflows and medium to high exfiltration rates.
