The Piscataway Creek watershed encompasses 69 square miles in Prince George’s County. Headwaters originate to the west and east of Andrews Air Force Base (AFB) (in the vicinity of Camp Springs, Clinton and Woodyard). On the southwest side of Andrews AFB two branches join to form Tinkers Creek, the major tributary to Piscataway Creek. Surface water runoff flows into Tinkers Creek, to Piscataway Creek, and eventually into the Potomac River. From the southeast of Andrews AFB, the mainstem receives drainage from nearly 1,500 acres of the base and is partially redirected to a man-made lake (Base Lake) on base. The Piscataway Creek mainstem has two named tributaries: Dower House Branch to the northeast and Butler Branch to the southwest. There are several small unnamed tributaries supplying input to Piscataway Creek.
The Maryland Department of the Environment (MDE) has identified the non-tidal portion of Piscataway Creek, Use IP – Water Contact Recreation, and Protection of Aquatic Life and Public Water Supply [Code of Maryland Regulations (COMAR) 26.08.02.08O(1)] in the State’s 303(d) as impaired by nutrients (1996), sediments (1996), bacteria (fecal coliform) (2002), and impacts to biological communities (2004). The listings for nutrients and sediments are in the tidal portion of Piscataway Creek. The document available below establishes a TMDL of fecal bacteria in the non-tidal portions of Piscataway Creek that will allow for the attainment of the designated primary contact recreation. The listings for nutrients, sediments, and impacts to biological communities will be addressed separately at a future date.
