A watershed, also known as a river basin, is the area of land that catches rain or snow and drains it into a marsh, river, lake or groundwater. This water makes its way into the Clinton River and eventually out to Lake St. Clair.

The Township resides in the Clinton River Watershed, North Branch of Clinton River Subwatershed, and the Stony-Paint Creek Watershed.  The Clinton River Watershed covers 760 square miles and includes over 1,000 miles of streams in addition to the 80-mile-long main branch. 

Washington Township works with the Clinton River Watershed Council, neighboring municipalities, and other agencies within our watershed to educate our residents and neighbors of the importance to protect, enhance, and celebrate the Clinton River, its watershed, and Lake St. Clair.
