WATERSHED
A WATERSHED is the area of land where all of the water that is under it (ground water) or drains off of it (surface water) goes into the same place.
• drained by a river, river system, or other body of water
Watersheds come in all shapes and sizes. A watershed is like a large bathtub. When a drop of water hits anywhere in that bathtub, it eventually finds its way to the drain. The edges of the bathtub define the watershed boundary. They can cross county, state, and national boundaries.
• Human activity within a watershed in one location can affect all locations
• separated from other watersheds by higher land (drainage divide)
