Summary: Water quality in this sub-catchment is unknown since no water quality sampling has occurred.
Issues: Sewerage overflows and exfiltration are likely to be a problem and some waterfront properties may be septic and non-sewered.
Knowledge Gaps: No sewerage or water quality data has been collected for this sub-catchment.
Recommendations: This is a small sub-catchment but has the same issues as many nearby areas. Water quality should be monitored, but this is difficult given the fact that there are no specific streams in the area. The condition of the sewer should be assessed.
