The Mispillion River is located in southeastern Kent County and northeastern Sussex County. It forms the dividing line between Kent and Sussex counties. There are nearly 70 miles of waterways plus several lakes and ponds in the watershed. There are four major water bodies in this watershed: Blairs Pond, Griffiths Lake, Haven Lake and Silver Lake. The headwaters of the Mispillion River origniate several miles inland and the river flows to the east where it drains into Delaware Bay.
The two major urban areas are Milford and Houston. Major land use in the area consists of agricultural lands and wetlands.
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.
