About Our Watershed

General Information

A watershed is the area of land where all of the water that is under it or drains off of it goes into the same place. John Wesley Powell, scientist geographer, put it best when he said that a watershed is:

"that area of land, a bounded hydrologic system, 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."

Watersheds come in all shapes and sizes. They cross county, state, and national boundaries. No matter where you are, you're in a watershed!

The Antietam Creek watershed is a small but important part of the Chesapeake Bay watershed. More than half of the state lies within the Bay watershed. Pennsylvania contains two major Bay watersheds: the Potomac, with 1,600 square miles; and the Susquehanna, with 21,00 square miles. Together, they total 40% of the entire watershed.
