The Nanticoke River begins its journey in southern Delaware, flowing southwest to the Chesapeake Bay through the Lower Eastern Shore of Maryland.
The Nanticoke watershed has focused development in a few small towns, including Seaford, Delaware.
DNREC's Wetland Monitoring and Assessment Program (WMAP) has been developing scientifically robust methods to monitor and evaluate wetlands in Delaware on a watershed basis. Learn more about the health of the wetlands in this watershed from the DNREC Wetlands Monitoring and Assessment Program.
