Watersheds

A watershed is an area of land where streams and rivers drain into one big area of water. I am a part of the Elm Fork Trinity River watershed #12030103.

Some benefits of watersheds would be that it provides shelter for fish, provides waters to cities and helps with pollution. Problems caused by people would be littering in the water and gasoline from boats in the water and polluting it.
