According to the results of monitoring studies conducted by Environment and Climate Change Canada scientists, the status of benthic macroinvertebrate communities in the St. Lawrence River ranges from moderate to poor depending on the sector concerned. An upstream-downstream gradient of degradation has been observed between Lake Saint-François and Lake Saint-Pierre. In Lake Saint-Pierre, all the coastal benthic communities have been exposed to pesticide contamination"--page 1.
