Manitoba Prairie Lakes and Eutrophication

Share This

Eutrophication, or the process of nutrient enrichment in water systems, causes pronounced deterioration of water quality and is a widespread environmental problem, one which affects the quality of many Manitoban prairie lakes.

These lakes have deteriorated due to excessive loading of nutrients, organic matter and silt, which in turn cause increased algae and other plant material growth and reduced water quality. The goal of this research is to identify lake remediation treatments and strategies appropriate for prairie lakes in Manitoba that have been affected by eutrophication, prioritizing management interventions for reducing the impact of lake eutrophication based on understood efficiency and other criteria.
