Summary of Results for 2016-17

In 2016-17 the Fitzroy Basin received a C grade for aquatic ecosystem health, with a decrease from a B grade last year to a C grade this year. Phys-chem results were generally good and salinity results decreased marginally across many catchments. pH results were generally excellent or good across all catchments. Nutrient results declined marginally compared to long-term condition whilst ecology remains patch across the basin. Toxicants improved for several catchments although Nogoa in particular experienced a significant downgrade from a B grade to an E grade. This was driven by paucity of data, as a single aluminium sample contributed to this catchment score.
