Macroinvertebrate populations provide additional perspective on aquatic life conditions in the river. Because many species are highly sensitive to pollution, and because they are relatively immobile, the assessment of macroinvertebrate populations can bring valuable insights on water quality. The Commission has conducted macroinvertebrate sampling each year since 1990, including site-specific studies, pool-wide studies and river-wide surveys.
