The Great Lakes are known for their beauty and the wealth of resources within and around them. The combined lakes contain the largest supply of fresh water on earth; 20% or one fifth of the earth's total fresh water, with more than 3,000 miles of shoreline, the Great Lakes not only form Michigan's geography, but also shape our economy, society, and environment.
The Great Lakes face threats including invasive species, urban and rural runoff, historical as well as new sources of contamination, and changes in climate. You can help protect our Great Lakes and all of Michigan’s rivers, lakes and streams and even groundwater! Ensuring the health of our water resources for generations to come depends on stewardship and education about water. Just like every drop of water matters, every effort does, too!
Become a water steward and Great Lakes champion!
