Anne Arundel Patapsco River Alliance works in the watersheds of the Patapsco River and its tributaries that are in Anne Arundel County. We plan to partner with other watershed organizations that either work in other areas of the Patapsco outside of Anne Arundel County, such as Blue Water Baltimore, or those that have already found their niche within the County's tributaries to the Patapsco Rivers such as Restore Rock Creek.
The Anne Arundel Patapsco River watershed includes the following sub-watersheds.
- Cabin Branch
- Stoney and Nabbs
- Curtis, Marley and Furnace
What is a watershed?
A watershed is an area of land that drains into a body of water such as a creek, river or bay. Since smaller bodies of water typically drain into larger bodies of water, there a complete network of sub watersheds that all connect to a larger watershed. For example there is the watershed for Marley Creek which is part of but is not inclusive of the watershed for the Patapsco River which is part of but not inclusive of the watershed of the Chesapeaike Bay. In this region, all streams, tributaries and rivers ultimately flow into the Chesapeake Bay.
Water drains both on the surface and underground. It is know as the universal solvent. Therefore, any pollution that occurs on the land of a watershed can evetually pollute the waterway. During a rain event , as the water moves over and through the land into the water making the waterway unhealthy. The types of pollution that enter our water include but are not limit to sediment, nutrients (fertilizers), pet waste, sewage (bacteria), persticides, and trash.
