This covered pool is really a good example of a watershed. The blue cover represents the watershed, the area in which precipitation that falls flows down-gradient towards the lowest part of the basin, the center of the pool cover in this case. Likewise, in nature, water flows towards a valley, river, or lake.
A watershed is the area of land where all of the water that falls in it and drains off of it goes to a common outlet.Watersheds can be as small as a footprint or large enough to encompass all the land that drains water into rivers that drain into Chesapeake Bay, where it enters the Atlantic Ocean.ot all precipitation that falls in a watershed flows out. To picture a watershed as a plastic-covered area of land that collects precipitation is overly simplistic and not at all like a real-world watershed.
