However, Lake Winnipeg has developed the worst algae problem of anymajor lake in the world. (Canadian Geographic magazine Nov/Dec 2006).
This algae is the result of excessive nutrients flowing into the lake from a variety of sources. Human activity contributes to this directly and indirectly in several ways, from runoff from agricultural fields, feed lots, urban lawns, golf courses, waste and household cleaning supplies/detergents that contain large amounts of phosphates.
Every year, about 8,000 tonnes of phosphorus enters the lake along with over 90,000 tonnes of nitrogen.
