Great Lakes Watersheds Map​

We like to say that everyone lives on waterfront property. This is because everything people do on land no matter if its located on a river or lake or not ends up in one of the Great Lakes. To illustrate this, we worked with The Nature Conservancy to create a new map of the Great Lakes.

The map color codes every drainage basin (watershed) in our region and demonstrates that no matter where you are located, you are in a watershed. A watershed can be as small as a few acres draining into a farm pond or as large as several thousand square miles for a major lake, such as one of our Great Lakes. For example, on this map, all the different watersheds for Lake Huron are a shade of green. All the water clean and polluted which flows into all those green watersheds eventually flows into Lake Huron.

We hope this map also communicates why its so important for all of us individuals, businesses, institutions, and governments to be stewards of the Great Lakes. Everything we do on our land matters. To learn how you can become a better steward, contact your local watershed organization in the United States or conservation authority in Canada.
