The Delaware Bay region stretches southeast from the widening of the Delaware River to the Atlantic Ocean. This region of 1,539 square miles includes the Maurice River Watershed in New Jersey and the Mispillion River Watershed in Delaware, as well as smaller sub-watersheds along both sides of a wide Delaware Bay. It is characterized by relatively flat coastal plain topography, extensive salt marshes, the occasional sandy beach along the shoreline, and a mixture of relatively large farms and low-lying forests inland, with modest but increasing development in the southern resort areas, especially along major roads. Recreational boating, fishing, and tourism are major economic benefits in this region, offering both challenges and opportunities. Runoff from agriculture and stormwater from increasing development (on shallow soils) are major concerns.
