The Chesapeake Bay watershed is a vast network of rivers and streams draining 64,000 square miles of land and pouring billions of gallons of fresh water into the Chesapeake Bay. This huge drainage basin is home to 15 million people and several thousand species of plants and animals.

How communities use their land and their water supply greatly affects not only the health of local streams, creeks and rivers, but also the Chesapeake Bay.

The following links to various maps show how significant a role towns throughout the watershed play of the health of the Bay.
