Watershed Area

What is a watershed? 

The entire area where a particular area's water naturally flows and flows forward in a stream is called the watershed of that stream.

• A watershed is a natural part of the natural landscape.
• A watershed is an area in which rainwater flows over the land surface, flows within that area and exits at a single point.
• A watershed is bounded by a watershed line (the crest line).
• Every body of water and every stream on the land surface has its own watershed.
• A watershed can be as small or as large as it is wide.
