Great Lakes Basin

The Great Lakes Basin is a large area that includes the five interconnected lakes—Superior, Michigan, Huron, Erie, and Ontario—as well as the surrounding land that drains into these lakes. It covers parts of eight U.S. states and two Canadian provinces. This basin is a vital natural resource, supplying drinking water, supporting industry and agriculture, and providing habitats for diverse wildlife. Its health depends on sustainable management to prevent pollution, invasive species, and overuse, ensuring the lakes continue to benefit people and ecosystems for generations.
