Final TMDLs Approved by EPA: Duck Neck Beach, Upper Chester River

Duck Neck Beach is located on the southern bank of the Upper Chester River Basin (basin number 02130510) on Maryland’s Eastern Shore in Queen Anne’s County,   The Chester River is approximately 44.5 km in length and its width ranges from 30 to 500 m upstream and approximately 5.4 km at its mouth (where it flows into Chesapeake Bay).  Duck Neck Beach has a length of 22 meters.  The drainage area, affecting the water quality of the public beach, is 15,901 acres.

Duck Neck Beach, a public beach, is located near the border between Kent and Queen Anne’s Counties on the southern bank of the Maryland 8-digit basin Upper Chester River (basin number 02130510). Duck Neck Beach is designated as a Use I water: Water Contact Recreation and Protection of Nontidal Warmwater Aquatic Life (COMAR The tidal portion of the basin was first identified in 1996 as impaired for fecal coliform (bacteria). In the 2008 Integrated Report of Surface Water Quality (Integrated Report), the bacteria impairment (enterococci) was clarified and identifies only Duck Neck Beach (assessment unit ID: MD-CHSTF-Duck_Neck_Beach). The designated uses in Upper Chester River were listed as impaired by sediments (1996), nutrients (1996), bacteria in tidal portions of the basin (1996, 2008), impacts to biological communities (2006), and methylmercury in fish tissue in one of the basin’s impoundments (Millington Wildlife Management Ponds) in 2004.  A nutrient TMDL was completed in 2006 for this basin.  The document below establishes a TMDL of enterococci bacteria for the waters of Duck Neck Beach that will allow for the attainment of its designated use.  The listings for sediments, impacts to biological communities and methylmercury in fish tissue within the Upper Chester River Basin will be addressed at a future date.
