                   e   Wallum tannin-stained freshwater water type used (as mapped by DES), however the
                       “Eastern sandplain water type” from the Mary Catchment may be more suitable due to pH
                       values recorded;
                   e   pH compliance is low, with the majority of records from 2.82 to 4.6;
                   e   Monitoring commenced in 2010, good sample size;
                   e   Excellent turbidity and electrical conductivity compliance, with significant improvement
                       since 2017;
                   e   Dissolved oxygen is virtually non-compliant, with median value of 37% saturation, with
                       overall low % saturation (17 - 70%).
