Accidental guardians: How reservoirs are decreasing nitrogen and phosphorus loads reaching Lake Winnipeg
Lake Winnipeg has been experiencing increasingly severe algae blooms since the 1990’s, earning it the title of “Canada’s Sickest Lake”. This “illness” stems from excess nutrients, primarily phosphorus and nitrogen, running off from agricultural lands, urban areas, and wastewater treatment plants. These nutrients result in various water quality problems, including excessive algae growth, which can block light, deplete oxygen levels, and release toxins into the water.
