What's a watershed? When you pour out a bucket of water in your yard, where does it go? Explore Michigan's rivers and watersheds in this new edition of our Michigan Watersheds Map.

Updated in 2021, this 26 x 36 inch poster uses high-resolution geographic data to show watershed boundaries at local and greater levels. The high-contrast colors are designed to match the new Great Lakes Basin map, making the two an attractive addition to a classroom, office, or home.
