Codorus Chapter Mission

The Codorus Chapter was founded in 1988 by a small, but dedicated group of individuals interested in preserving and enhancing the West Branch of the Codorus Creek. Over the years our chapter, like our home stream, has grown and flourished and now includes over 270 members. We strive to continually maintain an active schedule of fundraising, stream improvement, landowner relations, educational and public relations efforts.

Why Watersheds?


What is a watershed?

A watershed is an area of land that drains into a particular river,  lake or other body of water. 

Watersheds are sometimes called “basins” or  “drainage basins.”   We all live in a watershed. Some watersheds, like that of a stream or  creek, are small. Others, like the Chesapeake Bay watershed, are large. 

Bay 101

The Chesapeake Bay is rich in history and natural beauty. It is the  largest estuary in the United States and home to a huge number of  plants, animals and people. Watch the videos below to learn about some  of the critters that live here and the issues that affect Bay restoration. Learn more...

Bay History

The Chesapeake region has been around for a very long time.  Europeans arrived. Steel plows and axes allowed easier clearing of land for agriculture, firewood and forest products. Charcoal makers cut and burned large areas of forest to supply fuel for the early iron industry. Farms and towns replaced the forest in valleys and on h The growing population pushed west. By the 1850's, Penn's Woods supported an estimated 128,000 selfsufficient farms  But the story of the Bay began millions of years before that. Read more...

Bay Ecosystem

 An ecosystem is a complex set of relationships among living and  non-living things. Air, water, soil, sunlight, plants and animals –  including humans – make up an ecosystem. Ecosystems can be as tiny as a  patch of dirt in your backyard, or as large as the entire Chesapeake Bay  watershed. Learn more...

Bay Watershed

The Chesapeake Bay watershed spans more than 64,000 square miles. It  encompasses parts of six states—Delaware, Maryland, New York,  Pennsylvania, Virginia and West Virginia—and the entire District of  Columbia. More than 18 million people live in the Chesapeake Bay  watershed.   The Chesapeake Bay’s land-to-water ratio is 14:1: the largest of any  coastal water body in the world. This is why our actions on land have  such a big impact on the Bay’s health.
