| | Maryland DNR - Tributary Strategies: Patapsco & Back River Team |
 | | The Patapsco/ Back River basin drains approximately 630 square miles of land, including all of Baltimore City and portions of Anne Arundel, Baltimore, Carroll, and Howard Counties. |
 | | Larger waterbodies in the basin include Back River, Gwynns and Jones Falls, the North and South Branches of the Patapsco River, Lake Roland, Piney Run Reservoir, Liberty Reservoir, and Baltimore Harbor, a tidal embayment formed at the confluence of the Patapsco River and the Jones and Gwynns Falls. |
 | | The Patapsco and the Back Rivers, along with all tributary basins in the Chesapeake, contribute to and are impacted by nutrient pollution. |
