Final TMDLs Approved by EPA: Nanticoke River

The Nanticoke River is located on Maryland’s Eastern Shore in Dorchester and Wicomico Counties.  The Nanticoke River mainstem is in the lower Nanticoke River.  The Nanticoke River has a length of approximately 64 km and its width ranges from 140 to 300 m upstream and approximately 3 km at its mouth (where it flows into Chesapeake Bay).  The shellfish harvesting waters in the Nanticoke River extend from Runaway Point (near Station 14-05-025) on the Wicomico County Shore and Long Point on the Dorchester County Shore approximately 10 miles to the mouth of the river where it confluences with Tangier Sound.  Approximately 75% of the river basin adjacent to shellfish harvesting waters is tidal marsh.  The Nanticoke River restricted shellfish harvesting area has length of 6.3 km and a drainage area of 503,853 acres (2039.0 km2).

Nanticoke River (basin number 02130305) was first identified on the 1998 303(d) List submitted to U.S. Environmental Protection Agency (EPA) by the Maryland Department of the Environment (MDE).  The designated uses in Nanticoke River were listed as impaired by fecal coliform in tidal portions of the basin (1998), bacteria at two public beaches (1998, 2006), and impacts to biological communities in the tidal and non-tidal portions (2004).  In 2004, the fecal coliform listing was refined by identifying one restricted shellfish harvesting area within the basin.  The assessment unit listing code for this area in Maryland’s 303(d) List is MD-NANMH-NANTICOKE_RIVER.  The document available below establishes TMDLs of fecal coliform for the one restricted shellfish harvesting area in the Nanticoke River basin: the Nanticoke River mainstem.  The listings for impacts to biological communities and bacteria at two public beaches within the Nanticoke River basin will be addressed at a future date.
