                   e   Monitoring commenced in 2005, good sample size;
                   e   Turbidity compliance is good, although declined since 2017;
                   e   Temperature compliance has decreased since 2017, temperature ranges from 11 to 30
                       degrees;
                   e   Dissolved oxygen compliance is low, with median value of 41% saturation, with a wide %
                       saturation (8 — 159%) variation which may indicate a water quality issue;
                   e   pH compliance is low, with a recorded range from 5.2 to 8.4 which could indicate a water
                       quality issue.

                   e   This site is mapped by the Department of Environment and Science (DES) as Wallum tannin-
                       stained freshwater water type however the water quality displays characteristics of the
                       Upper Estuary water type (owing to EC levels recorded; average of 14,056 uS/cm);
                   e   Monitoring commenced in 2005, good sample size;
                   e   Dissolved oxygen is non-compliant, with median value of 41% saturation, with overall low %
                       saturation (4 — 73%) which indicates a water quality issue;
                   e   pHcompliance is very low, with a recorded range from 3.5 to 8.3 which indicates a water
                       quality issue.
