What is Lake Superior Day? Lake Superior day is a special day that encourages people to appreciate living next to one of the world’s biggest freshwater lakes.
Why is it being organized? Although Lake Superior is the cleanest of the five Great Lakes, it too is vulnerable to pollution, poisoned fish, invasive species, loss of habitat and over development. The special day reminds us how important the lake and its surrounding basin is to our health, food supply, recreation opportunities, economy and quality of life. Lake Superior Day is a time to highlight the many ways we use the lake every day and to find ways to protect it.
