Final TMDLs Approved by EPA: Breton Bay

The Breton Bay watershed encompasses over 55 square miles of land on Maryland’s coastal plain between the Potomac and Patuxent Rivers.  Breton Bay is 6.5 miles long and drains 35,418 acres. Breton Bay ultimately drains to the Chesapeake Bay, and is a part of the Lower Potomac Tributary Strategy Basin.

Breton Bay (basin number 02140104) 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 sediments, nutrients, and fecal coliform, with listings of biological impacts in specified non-tidal portions added in 2004.  On the 2004 303(d) List, the fecal coliform listing was clarified with the identification of Cherry Cove Creek as the specific area of impairment.  The document available below establishes a TMDL of fecal coliform for Cherry Cove Creek.   A nutrient TMDL for Breton Bay was developed in 2005; the suspended sediment and biological impairments within the Breton Bay basin will be addressed at a future date.
