The mission of the Anacostia Watershed Society is to protect and restore the Anacostia River by bringing partners and communities together to achieve a clean and safe Anacostia River for the benefit of all living in its watershed and for future generations. Their vision is to make the Anacostia River and its tributaries swimmable and fishable, in keeping with the Clean Water Act, for the health and enjoyment of everyone in the community. Community involvement is critical to achieving this vision and AWS seeks win-win solutions through strong partnerships and coalitions, with all parts of the community, government, and other stakeholders. AWS accomplishes this by hosting various community events and taking on ambitious projects.

Despite centuries of development and pollution, the Anacostia River Watershed is still a remarkably rich natural area.  A recent inventory of species, called a BioBlitz, counted 522 unique species, including rare and endangered species, birds, fish, mammals, amphibians, insects and many more.  Journey along the river and you might see bald eagles, beavers, ospreys, cormorants, white perch, striped bass, crayfish, herons, turtles, egrets, otters, red fox, shad, kingfishers, catfish and even mussels!   

The Anacostia Watershed Society is currently located at The George Washington House: 4302 Baltimore Avenue
Bladensburg, MD 20710. This amazing organization is celebrating 35 years of restoring the Anacostia River in 2024 and you can learn more about their efforts at

Anacostia River History

For thousands of years before European explorers and settlers sailed up the Anacostia, Native Americans hunted and farmed along its shores and feasted on the bounty of fish and seafood they found in the river. In 1608, when Captain John Smith sailed up the Potomac and into the Anacostia, he marveled at its depth and clarity. The tribe he found living at the mouth of the river were traders and the name he recorded for them was “Nacotchtank,” which seems derived from the Native word for “a town of traders.” Over the years, that name evolved to “Nacostine” and later “Anacostine,” eventually giving us the names which we use today - “Anacostan” for the tribe and “Anacostia,” for the river.

Life got hard for the Anacostans in the 17th century, their location was choice for trade, but they were also the first tribe to be attacked by other Native tribes from the north. The settlers brought new diseases, which afflicted Natives throughout the Chesapeake, and conflicts that also cost them lives. In the 1660s, hard times caused the Anacostan chief to leave his tribal homestead, which was located where the Joint Anacostia-Bolling Base now sits. That land and much of the shoreline upriver on the Anacostia was cleared for farming by the settlers. (For more information about local indigenous history, visit DC Native History Project).  

In the 18th century, the Port of Bladensburg served as a major center for colonial shipping. Since the river was 40 feet deep, it was able to accommodate ocean going ships.  The 19th  century’s major industrial activity, including ship building at the Washington Navy Yard and coal gasification further upriver, supported a vibrant economy, but also contributed to the destruction of wetlands and the pollution that we still battle today. 

Development along the river led to the destruction of the forests, meadows and wetlands that make for a healthy watershed.   As run-off and sediment clogged the river and reduced its depth, and as the population living near the river increased, flooding became a serious problem.   In what we now recognize as a counterproductive approaches, the Army Corps of Engineers built a series of levees designed to control flooding, further degrading the natural systems of the Anacostia.
