Environmental issues

Lake Winnipeg is suffering from many environmental issues such as an explosion in the population of cyanobacteria, caused by excessive amounts of phosphorus seeping into the lake. The phosphorus levels are approaching a point that could be dangerous for human health.

The Global Nature Fund declared Lake Winnipeg as the "threatened lake of the year" in 2013.

In 2015, there was a major uptick of zebra mussels in Lake Winnipeg, the reduction of which is next to impossible because of a lack of natural predators in the lake. The mussels are devastating to the ecological opportunities of the lake.
