Fig. 1: Proportion of water quality monitoring sites/catchments showing each type of trend between 2000 and 2019.

Each panel contains the summary of site-level trend types for the five water quality parameters across Australia (a) and within each of the eight major river basins where long-term water quality data is present (b–i). The river basins are ordered by the total number of sites analysed. The total number of catchments analysed are shown as labels on the top for each region/parameter.
