Great Lakes Awareness Day

Great Lakes Awareness Day is an annual observance in both the United States and Canada that highlights the importance of the Great Lakes. These freshwater systems play a critical role in the environment, regional economies, and daily life for millions of people. The observance takes place on the Monday of the first full week in May.

History of Great Lakes Awareness Day

Great Lakes Awareness Day was established to increase public understanding of environmental challenges facing the Great Lakes, with particular attention to pollution and ecosystem protection. Since 2018, the observance has placed added emphasis on safeguarding these freshwater resources for future generations.

The Great Lakes form one of the largest freshwater systems on Earth, comparable in scale to Lake Baikal and major freshwater reserves in Africa and Antarctica. Concerns about their preservation grew as industrial activity and transportation expanded throughout the region.

The creation of the observance was also influenced by public debate surrounding the Line 5 pipeline, which passes beneath the Straits of Mackinac and affects Lake Michigan and Lake Huron. Environmental groups raised concerns about potential risks to water quality.

During the 20th century, intensive industrial use and agricultural development around the lakes led to rising levels of pollution. By the 1950s, scientists began reporting increased concentrations of harmful substances. In the 1970s, the United States and Canada launched joint environmental programs aimed at restoring water quality and protecting the Great Lakes ecosystem.
