How Healthy is Your Favorite Water Basin

Think of your favorite river, lake or body of fresh water. A basin is the land that water flows across or under on its way to that river, lake or other freshwater resource. Just as a bathtub catches all of the water that falls within its sides, a basin sends all of the water falling within it to a central river, lake, estuary or the ocean. So how healthy was your freshwater basin?

While this is by no means a scientific assessment, take this quiz while thinking of your favorite river or lake to see what grade it might get.
