Final TMDLs Approved by EPA: South River

The South River is located on Maryland’s Western Shore in Anne Arundel County, MD.   The upper restricted portion of South River flows southeast into the unrestricted portion, ending approximately 5 km from the mouth of the South River.  The second restricted shellfish harvesting area, Duvall Creek, is located on the northern side of South River.  It flows to the south and empties into South River.  The third restricted shellfish harvesting area, Selby Bay, is located about 3 km northwest of the South River mouth.  The length of Selby Bay is about one km.  Ramsey Lake is a small embayment of approximately two km in length and approximately two km northwest of the South River mouth.  South River has a width exceeding two km, whereas Duvall Creek, Selby Bay, and Ramsey Lake are relatively narrow with widths from 500 m to 800 m.  The South River restricted area has a drainage area of 33,482.9 acres (135.5 km2).  Duvall Creek has a drainage area of 516.1 acres (2.1 km2), Selby Bay has a drainage area of 365.0 acres (1.5 km2), and Ramsey Lake has a drainage area of 331.6 acres (1.3 km2). 

South River (basin number 02131003) was first identified on the 1996 303(d) List submitted to U.S. Environmental Protection Agency (EPA) by the Maryland Department of the Environment (MDE) as impaired by nutrients, sediments, and fecal coliform, with listings of biological impacts in specified non-tidal portions added in 2002 and 2004, and a listing of PCB impairment in fish tissue added in 2002 for the tidal portion.  On the 2004 303(d) List, the fecal coliform impairment was clarified with the identification of four specific restricted shellfish harvesting areas within the basin.  The document available below addresses the fecal coliform impairment listings of the areas identified:  South River; Duvall Creek; Selby Bay; and Ramsey Lake.  The nutrient, sediment, biological, and toxic impairments within the South River basin will be addressed at a future date.
