Total Maximum Daily Loads of Fecal Coliform for the Restricted Shellfish Harvesting Area in the Lower Wicomico River Basin in Wicomico and Somerset Counties, Maryland

Final TMDLs Approved by EPA: Lower Wicomico River

Lower Wicomico River is located on Maryland’s Eastern Shore in Wicomico and Somerset Counties.  The Lower Wicomico River mainstem is in the lower portion of the Wicomico River.  The Wicomico River has a length of approximately 33 km and its width ranges from 130 to 180 m upstream and approximately 1.6 km at its mouth (where it flows into Chesapeake Bay just south of Nanticoke River).  The Lower Wicomico River restricted shellfish harvesting area has length of 6.2 km and a drainage area of 124,790.4 acres (505.01 km2).

Lower Wicomico River (basin number 02130301) was first identified on the 1996 303(d) List submitted to U.S. Environmental Protection Agency by the Maryland Department of the Environment (MDE).  The designated uses in Lower Wicomico River were listed as impaired by sediments (1996, 2002), nutrients (1996), and fecal coliform in tidal portions of the basin (1996), and impacts to biological communities in the non-tidal portions (2002).  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-WICMH-WICOMICO_RIVER.  The document available below establishes a TMDL of fecal coliform that will allow for the attainment of the shellfish harvesting designated use in the one restricted shellfish harvesting area of the Lower Wicomico River basin: the Lower Wicomico River mainstem.  A TMDL for nutrients was completed in 2001.  The listings for sediments and impact to biological communities within the Lower Wicomico River basin will be addressed at a future date.
