Question

What parts of the environment, natural and manmade, make up a watershed?

Answer 1

Explanation:

The definition of watershed is

"any point on uphill from where water flows downstream wither in the form of river, stream or rain water".

From the definition we can say that watershed (either natural or man made) would me anything that is present in that area where the water flows downstream to houses, parks, and dams.
