The categories above represent combined improvements in all regions. For each region, this means reducing the length of specified rivers and lakes in the red and orange categories, and increasing the length of specified rivers and lakes in the yellow, green and blue categories.
The categories are based on water quality in terms of the two human health attributes, E. coli and cyanobacteria – planktonic in Appendix 2 of this national policy statement.
For rivers and lakes, the target categories are the same as the E. coli table attribute states. However, the categories do not include the 95th percentile of E. coli/100 mL numeric attribute state if there is insufficient monitoring data to establish the 95th percentile.
For lakes, the categories are also based on the cyanobacteria – planktonic attribute states, however, to provide additional granularity for tracking improvements over time, the D band has been split into two categories (orange and red) as follows:
a. orange means the lake has between 1.8 and 3.0 mm³/L biovolume of planktonic cyanobacteria, using an 80th percentile; and
b. red means the lake has more than 3.0 mm³/L biovolume of planktonic cyanobacteria, using an 80th percentile.
For lakes, the lowest category for either E. coli or cyanobacteria – planktonic applies."
