Watersheds are Everywhere
Stand anywhere on the surface of planet Earth and you're standing in a watershed. Water falling to the ground as precipitation is absorbed into the soil--becoming groundwater--and drains from the surface of the land into the nearest creek or stream. Streams join other streams and flow into rivers which, in turn, are fed by the groundwater through underwater springs. All of the area that drains into each creek, stream, or river is called its watershed.
