About Codorus Creek

The Codorus Creek Watershed is home to over 200,000 residents who live, work and play here. Codorus Creek drains 278 square miles of southwestern and central York County, Pennsylvania, with over 447 miles of streams, three major reservoirs, and many more ponds and wetlands.
 
Clean water is used for agriculture, industry, drinking, and recreation. Biodiversity includeds a range of native and invasive flora and fauna. However, Codorus Creek and some of it's many tributaries are impaired by nonpoint sources of pollution: sediment, nutrients and toxic substances.
