A watershed is the area of land where all of the water that falls in it and drains off of it goes to a common outlet.

Based on the principle of gravity. Water always flows down.

Size of watersheds varies depending on scale

River basins are collections of smaller watersheds

If we are looking at the health of our water, why does knowing the extent of the watershed help you understand pollutants?

Find how water moves around Fremont

Now you get to make a watershed! Needs to show how the water moves and where does it end up You need to be able to show the boundaries of your watershed.
