Page Lagoon discharges into tributaries of the Red River of the North, which flows north through North Dakota and Manitoba into Lake Winnipeg. The Red River Basin is a flat, fertile agricultural region where nutrient runoff is a concern. The plant's secondary treatment reduces organic pollutants and nutrients, helping to mitigate eutrophication risks in Lake Winnipeg, a large freshwater lake that supports fisheries and recreation.
