Drinking (D), Recreational (R), Fisheries (F), Agriculture (A), and Consumption of Fish (C) water quality objectives are used to monitor water quality on the North Saskatchewan River. The lowest numerical level was selected for each variable from the various water use objectives to ensure that the highest level of protection is given to protect the entire aquatic environment.
