What is a Watershed?
An area of land where all of the water that is under it or drains off of it goes into the same place; or

"that area of land … within which all living things are inextricably linked by their common water course and where, as humans settled, simple logic demanded that they become part of a community."
-John Wesley Powell, scientist, geographer

Watersheds come in all shapes and sizes. They cross county, state, and national boundaries. In the continental US, there are 2,110 watersheds.
