Delaware Estuary Watershed Database and Mapping Project

The Delaware Estuary Watershed Database and Mapping Project is a collaboration between NOAA's Office of Response and Restoration and the US EPA Hazardous Site Cleanup Division. The major goal is to support land revitalization efforts at the regional, federal, state and local levels.

The Delaware Estuary has three major ecological zones distinguished by differences in salinity, turbidity, and biological productivity (Santoro 2004). These zone boundaries are approximate and vary with seasonal and climatic changes.  The Upper Zone is tidal freshwater and extends from Trenton,  New Jersey to Marcus Hook, Pennsylvania. Although this project is focused on the Upper Estuary, there are very important watershed-wide programs and initiatives underway that benefit the Delaware Estuary and larger Delaware River Basin.
