What is a watershed?

A watershed is an area of land wherein all of the rain and melting snow drains to a single body of water such as a creek, river, or lake. Nearly all of Michigan’s watersheds eventually flow into one of the Great Lakes.

Why are watersheds important?

  • Healthy watersheds reduce flood risk, support crops, filter pollutants, mitigate effects of climate change, and boost human wellbeing.
  • Our actions upstream have consequences downstream.
  • Water is only as clean as the land it flows over.
  • A river or lake is only as healthy as the water draining into it.

Michigan Watersheds Poster

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. 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.
