The application of correspondence analysis to data for turbidity, inorganic nitrogen, and inorganic phosphorus gathered at 112 stations located in the Cornwall‐Quebec reach of the Saint Lawrence River allows the behavior of these three parameters to be detailed. A cluster analysis applied to the results of correspondence analysis leads to the definition of homogeneous zones which are characterized by values of the three parameters considered. The results obtained enter into the design processes of quality network for the Saint Lawrence River by allowing for the elimination of a certain number of stations.
