On the Map
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.
Our watershed has over 41 miles of streams, all ultimately draining into the Back River and then the Bay. In addition to Herring Run, there are seven main tributaries:
- Western Branch
- Chinquapin Run
- Tiffany Run
- Armistead Run
- Biddison Run
- Moores Run
- Redhouse Run
We also have over 1500 acres of parkland, which are predominantly located directly around these waterways.
