We all live in a watershed, and watersheds get bigger as we go downstream. Our local watershed may be just our street, but if we follow the way the water flows, we will discover we live in more and bigger watersheds that contain our local street watershed.  For example, the Appomattox River Watershed is part of James River Watershed, which in turn is part of the Chesapeake Bay Watershed.  Often the smaller ones are termed sub-watersheds.
