The Mackay-Whitsunday-Isaac Healthy Rivers to Reef Report Card gives ‘school report’-style grades to different elements of waterway health across freshwater, estuarine and marine environments. For each environment, a number of indices (dark orange) are reported on. These are broken into a series of indicator categories (pale orange) and then indicators (blue) (Figure 1).

Figure 1. Environmental indices (dark orange), indicator categories (pale orange; where not applicable no category is listed) and indicators (blue) used to assess the condition of waterways in the Mackay-Whitsunday-Isaac Region. The monitored waterway type  is represented in the water drops as per the legend (grey = no data). Note: Litter is also assessed in urban areas. *The fish barriers indicator has three measures.

Note: TSS = total suspended solids, DO = dissolved oxygen, DIN = dissolved inorganic nitrogen, FRP = filterable reactive phosphorus, NOx = oxidised nitrogen, PP = particulate phosphorus, PN = particulate nitrogen, dist. = distance, CTF = cease to flow, CV = coefficient of variation.
