                       •      Chlorophyll a was highest upstream of the STP outfall, represented in B8. Recorded
                              values notably decreased at B3, immediately downstream of the outfall point, before
                              remaining consistent at monitoring sites further downstream towards the ocean
                              (Figure 19)

                       •      Chlorophyll a to pheophytin ratio and suspended solids results showed an increase
                              down the catchment with the highest concentration at B1 before decreasing to
                              background levels at SW3 (Figure 20, Figure 21).

                       •      Estimated water flow was the highest at the point of the STP outfall and remained
                              relatively consistent at sites downstream (Figure 22).
