What is a Watershed?
A watershed is an area of land where all of the water, on the surface and underground, drains to a common place such as a lake, river or the ocean. Watersheds come in all sizes and cross city, county, state and national political boundaries. For more information on watershed sizes visit the USGS Water Resources website.
All living things, including humans, are connected in a watershed so even if you don't live near a body of water, your everyday actions may affect water quality because you are always in a watershed.
