What is a Watershed?

The watershed of a river includes the entire area of land that drains, or ‘sheds’, its rain or snow melt into that river. The boundary of a watershed is based on the elevation and natural contours of a landscape.

The area surrounding a smaller river or creek which contributes to a larger river system is called a subwatershed. The West Credit River is a good local example of a subwatershed – this river contributes water to the Credit River.
