Water Quality Analysis of Fecal Coliform for Herring and Turville Creek of the Isle of Wight Bay Basin in Worcester County, Maryland

Water Quality Analyses (WQA) with EPA Concurrence of MDE's Findings:
Isle of Wight Bay

The Isle of Wight Bay basin is located on Maryland's Eastern Shore in Worcester County, Maryland.  A single restricted shellfish harvesting area in the Isle of Wight Bay basin is addressed in the report available below: Herring and Turville Creek.  Herring Creek has a length of 3.7 km and a width ranging from 120 to 280 m.  Turville Creek has a length of 2.9 km and a width ranging from 100 to 200 m.  The joined creek has a width of 450 m at the mouth, where Herring and Turville Creek flows to the northeast into Isle of Wight Bay.  The Herring and Turville Creek restricted shellfish harvesting area has a drainage area of 7,994.5 acres (32.4 km2).

Isle of Wight Bay (basin number 02-13-01-03) 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 and fecal coliform in tidal portions (1996) and impacts to biological communities in the non-tidal portion of the watershed (2004).  On the 2004 303(d) List, the fecal coliform listing was clarified by the identification of Herring and Turville Creek as the specific area of impairment. 

Recent monitoring data show that the applicable water quality criteria for fecal coliform are being met in Herring and Turville Creek.  As a result, TMDLs of fecal coliform are not necessary to achieve water quality standards in that watershed.  Barring the receipt of any contradictory data, the report available below will be used to support the bacteria listing change for Herring and Turville Creek from Category 5 (“waterbodies impaired by one or more pollutants and requiring a TMDL”) to Category 2 (“surface waters that are meeting some standards and have insufficient information to determine attainment of other standards”) when MDE proposes the revision of Maryland’s 303(d) list for public review in the future.  A TMDL to address the nutrient listing of Herring and Turville Creek, as part of the Northern Coastal Bay Watershed, was submitted and approved in 2001.  Other impairments of the watershed will be addressed separately at a future date.
