As home to 20 percent of the world’s supply of surface freshwater, the Great Lakes benefit all of us in so many ways. Our work to protect these lakes and preserve their legacy of clean water for generations is made possible by our generous supporters.

Every gift is appreciated and makes a difference in protecting the lakes. Special thanks to these institutions:
