Ever wonder where all that rain and melting snow goes when it washes down the drain in the parking lot? In most of Macomb County, this water makes its way into the Clinton River and eventually out to Lake St. Clair. Both the Clinton River and Lake St. Clair has a watershed. A watershed is all the land that drains to a common body of water, such as a river, lake, or stream. The watershed map shown depicts these watersheds' sub basins, also known as subwatersheds.
