The North Branch of the Potomac River forms the border between Maryland and West Virginia from its origin at the Fairfax Stone downstream to its confluence with the South Branch of the Potomac. The Lower North Branch of the Potomac River is defined as the reach between its confluence with the Savage River and the South Branch of the Potomac River. Wills Creek flows through the town of Cumberland discharging into the Lower North Branch. The drainage area of the Lower North Branch Potomac River watershed is 73,144 acres.
Lower North Branch Potomac River (basin code 02141001), located in Allegany County, Maryland, was identified on the State’s list of WQLSs as impaired by cadmium (Cd) (1996 listing), sediments (1996 listing), nutrients (1996 listing), low pH (1996 listing), fecal coliform (2002) and impacts to biological communities (2002 listing). The information used for listing Cd is suspect due in part to sampling and analysis methods available at the time, and assessment inconsistencies that led to the listing in 1996.
