For decades, if you mentioned the Washington DC Anacostia River to a local, you’d probably get a sympathetic grimace or a joke about three-headed fish. It was the "forgotten river." While the Potomac got the monuments, the regattas, and the postcard views, the Anacostia got the runoff. It became a literal boundary of segregation and neglect. But things are changing fast. Honestly, if you haven't stood on the 11th Street Bridge Park site lately, you’re missing the biggest urban environmental story in the country.
It’s messy. It’s complicated. And it’s actually working.
The river isn't just a body of water; it’s a 8.7-mile stretch of history that cuts through the heart of the District. People think it's just a polluted stream, but the Anacostia River is actually a tidal estuary. That means it breathes. The water pushes in from the Chesapeake Bay and pulls back out, carrying the weight of Maryland’s suburbs and DC’s industrial past with it.
The Toxic Legacy and the Big Dig
You can’t talk about the Washington DC Anacostia River without talking about the "Combined Sewer System." This is the boring technical stuff that explains why the river smelled like a locker room for fifty years. Back in the day, DC’s pipes handled both rainwater and raw sewage. When it rained hard? Everything overflowed right into the river.

DC Water’s "Clean Rivers Project" changed the game. They built these massive, terrifyingly large tunnels—think the size of a subway tunnel—hundreds of feet underground to catch that overflow. The Anacostia River Tunnel system has already captured billions of gallons of sewage that would have otherwise ended up floating past Navy Yard.
Since the first phase of the tunnel opened in 2018, overflow volume has dropped by nearly 90%. That’s a staggering number. You can actually see the difference in the water clarity near Kenilworth Aquatic Gardens.
But it’s not just about the sewage.
There's the "Legacy Sediment" problem. Basically, the riverbed is a graveyard for chemicals from the old Washington Navy Yard and the Pepco Benning Road plant. Polychlorinated biphenyls (PCBs) and lead don't just wash away. They sit there. This is why the Anacostia Riverkeeper and other groups still warn against eating the fish you catch. It’s a heartbreaking reality for the subsistence fishers—mostly from immigrant or lower-income communities—who rely on the river for food despite the warnings.
Why the Swimming Ban Still Exists
"Can I swim in the Anacostia?"
Short answer: No. Long answer: Not yet, but maybe sooner than you think.
Swimming has been illegal in DC’s rivers since 1971. Every summer, the Anacostia Riverkeeper hosts "Splash" events where they try to get special permits for supervised swims, but the bacteria levels are still a gamble. After a heavy rain, the E. coli counts spike. It’s a numbers game. You need several days of dry weather for the river to be "safe" by EPA standards.
There is a real push to make the Washington DC Anacostia River swimmable by the end of the decade. It sounds insane to anyone who grew up here in the 90s, but the data is actually trending that way. We're seeing more ospreys. We’re seeing bald eagles nesting near the golf courses. Nature is remarkably resilient when you stop actively poisoning it.
The Gentrification Tightrope at Navy Yard
Go down to the Yards Park on a Friday night in July. It’s beautiful. There are kids splashing in the fountains, people drinking $16 cocktails at luxury bars, and dogs everywhere. This is the new face of the Washington DC Anacostia River.
But there’s a tension here that most travel blogs ignore.
On the west bank, you have the booming Navy Yard and Capitol Riverfront. It’s shiny, glass-heavy, and incredibly expensive. On the east bank—Anacostia, Fairlawn, and Barry Farm—you have communities that have been there for generations, watching the property taxes rise as the river gets cleaner. The river used to be a barrier because it was gross. Now, it’s a barrier because it’s a "view" that developers want to monetize.
The 11th Street Bridge Park project is trying to bridge this gap, literally. It’s an elevated park built on the old bridge piers. Unlike the High Line in NYC, which just sort of happened and drove prices through the roof, the planners here spent years talking to Ward 7 and 8 residents. They’re trying to build in "equitable development" so the people who lived through the "smelly river" years actually get to stay and enjoy the "clean river" years.
It’s a bold experiment. Will it work? Kinda depends on who you ask.
Secret Spots Most People Miss
If you really want to experience the Washington DC Anacostia River, get out of the Navy Yard. Go north.
- Kenilworth Aquatic Gardens: This is the only National Park site dedicated to water plants. In July, the lotus flowers and water lilies are massive—like, Alice in Wonderland massive. It’s one of the few places where the river feels like it did 400 years ago.
- Kingman and Heritage Islands: These are man-made islands created from river dredgings in the early 1900s. They’re wild. You’ll forget you’re in a city. There are trails, birdwatching spots, and it’s a prime location for the Anacostia River Festival.
- Bladensburg Waterfront Park: Technically in Maryland, but this is where the river starts to get interesting for kayakers. It’s quiet. You can rent a boat and paddle down into the District, watching the skyline change from trees to stadiums.
The Plastic Problem: Trash Traps and Tensions
One thing that will still bum you out is the trash. Even if the sewage is mostly gone, the "floatables" remain. Every time it rains in the suburbs of Prince George's County, thousands of plastic bottles, Styrofoam cups, and footballs wash down into the DC section of the river.
The Bandalong Trash Traps are these clever floating cages that catch the junk. They work, but they're just a Band-Aid. The real solution is the 5-cent bag tax in DC and the Styrofoam bans, but until Maryland and DC are perfectly aligned on litter laws, the river is the ultimate recipient of our bad habits.
It’s frustrating. You’ll see a Great Blue Heron standing on a pile of discarded Gatorade bottles. That’s the Washington DC Anacostia River in a nutshell: incredible natural beauty fighting a constant war against urban neglect.
What about the fish?
The fish are the "canary in the coal mine." We have American Shad, Hickory Shad, and Striped Bass moving through these waters. The shad recovery has been a major success story, thanks to the removal of barriers like the Westphalia Dam.
But then there's the Snakehead.
The Northern Snakehead is an invasive species that looks like something out of a horror movie. They can breathe air. They have teeth. They’re actually delicious (if you catch them in cleaner parts of the watershed), and they’ve become a weird sort of cult icon for local anglers. They represent the grit of the Anacostia. They shouldn't be here, they survived the worst of the pollution, and now they’re thriving.
How to Actually Support the River
If you want to do more than just walk along the boardwalk, there are specific things that actually help.
Stop using lawn fertilizers if you live in the DMV area. Seriously. That nitrogen runs off into the storm drains and fuels algae blooms that kill fish in the Anacostia. It’s a direct line from your green lawn to a dead river.
Volunteer for a "trash sort." Groups like the Anacostia Watershed Society don't just pick up trash; they categorize it to use the data for lobbying. When they can prove that 40% of the trash is a specific brand’s bottles, they can push for better corporate responsibility.
Take a free boat tour. The Anacostia Riverkeeper offers these. They aren't "tourist" boats; they're educational. You’ll see the outfalls, the nesting sites, and the construction of the new bridges. Seeing the river from the water level changes your perspective entirely. You stop seeing it as a "problem" and start seeing it as a neighbor.
Actionable Steps for Your Visit
- Check the Bacteria Map: Before you go near the water, check the Anacostia Riverkeeper’s "Swim Guide" website. They test the water weekly during the summer. If it’s red, stay out of the splash zone.
- Rent a Kayak at Ballpark Boathouse: It’s located right near Nats Park. Paddle upstream toward the Navy Yard for a view of the USS Barry (well, where it used to be) and the decommissioned warships.
- Bike the Anacostia River Trail: This is one of the best-kept secrets in DC. It’s 20 miles of paved trail that connects the District to Maryland. It’s flat, fast, and gorgeous.
- Visit the Anacostia Community Museum: It’s a Smithsonian, but it’s tucked away in the neighborhood. They often have deep-dive exhibits on the environmental justice history of the river.
- Eat Local: If you’re at the Navy Yard, skip the chains. Go to the places that have been supporting the waterfront, or cross the bridge and grab food at the Anacostia Arts Center.
The Washington DC Anacostia River is no longer a lost cause. It’s a work in progress. It’s a place where you can see the scars of the past and the possibilities of the future at the exact same time. It’s not "restored" yet—not by a long shot—but it’s no longer being ignored. And that makes all the difference.
