The Herring Run Watershed is a 44 square mile watershed making up the northeast side of Baltimore City and the south central side of Baltimore County. It is actually a subwatershed within the larger Back River watershed, which extends all the way out to the Chesapeake Bay.
Roughly bounded by York Rd. to the west, Joppa Rd. to the north, 695 to the east, and Eastern Ave. to the south, the Herring Run Watershed encompasses over 50 neighborhoods, such as Original Northwood, Bel Air Edison, Hamilton, Stoneleigh, Parkville, Overlea, and Rosedale.
