Two tragic drownings in the Potomac River over a span of just a few weeks have Montgomery County officials scrambling for solutions. County Executive Marc Elrich recently acknowledged the heartbreak, noting that local authorities are actively mulling stricter enforcement and tougher rules to keep people out of the dangerous waters. It’s a familiar script. A tragedy occurs, public outcry follows, and politicians promise new regulations.
But here’s the harsh reality: passing more laws won't magically fix a problem rooted in human nature and geography.
People don't swim in the forbidden stretches of the Potomac because they checked the local legal code and found a loophole. They swim there because it's hot, the water looks inviting from the shoreline, and they completely underestimate the lethal power lurking just beneath the surface.
The Deadly Illusion of Mather Gorge and Great Falls
If you look at the Potomac River near Great Falls or Mather Gorge on a sunny July afternoon, the water can look deceptively peaceful. This visual trick fools swimmers every single year.
What you can't see from the banks is the extreme underwater topography. The riverbed drops off suddenly into deep, jagged trenches. Massive boulders hide just beneath the surface, creating powerful hydraulic undertows. When millions of gallons of water force through these narrow rocky gorges, it creates a washing-machine effect.
Even Olympic-level swimmers can't fight a Potomac undercurrent. Once the river pulls you under, the hydraulic pressure traps your body against underwater rocks. You don't just struggle to swim; you physically cannot break free.
The legal reality is that swimming and wading are already illegal in these high-risk zones. The Code of Federal Regulations (36 CFR 7.96) explicitly bans swimming or wading when entering the river from National Capital Region Parks, like the C&O Canal or Great Falls Park. On the state level, the Code of Maryland Regulations (COMAR) backs this up, outlawing recreational water entry in the treacherous stretches leading down to the Washington, D.C. line.
Exceptions exist only for boaters, kayakers, or paddleboarders who are actively using a vessel and wearing a U.S. Coast Guard-approved personal flotation device (PFD). For standard swimmers, it is already a punishable offense carrying fines of $200 or more.
The Logistics Nightmare of Enforcement
If the laws are already on the books, why are people still dying? Because you can't police an entire river.
Montgomery County officials admit they face a massive logistics hurdle. The Potomac River shoreline stretches for miles, littered with remote, unregulated access points. Park police and local first responders don't have the manpower to station a guard at every rocky outcrop or hidden trail ending.
Putting up miles of chain-link fences along a scenic national park isn't a realistic option either. It would destroy the natural environment and cost millions of taxpayer dollars, all while determined swimmers would likely just bring wire cutters or find a way around.
When the heat index hits triple digits, people seek relief. If they don't see a police cruiser parked at the trailhead, a warning sign isn't going to deter them.
Real Solutions That Actually Save Lives
Instead of writing new ordinances that officials can't enforce, Montgomery County needs to pivot its strategy toward aggressive education and accessible alternatives.
Upgrade the Signage Strategy
The current "No Swimming" signs clearly aren't working. They look like standard bureaucratic warnings. The county needs high-impact, graphic signage at every single major trail entry point. Don't just say it’s illegal; explain why it's lethal. Use stark diagrams showing how underwater currents trap bodies. Put the actual drowning statistics out in the open.
Expand Access to Safe Water
As Marc Elrich recently pointed out, the county offers plenty of safe public pools. But for many residents, getting to a county pool requires a car or a long bus ride, and entry fees add up for large families. If we want people to stop risking their lives in a dangerous river, we must make municipal pools cheaper, more accessible, and heavily promoted during heatwaves.
Target the Right Demographics
Data consistently shows that teenagers and young adults are the most likely to ignore swimming bans due to peer pressure and a feeling of invincibility. Public safety campaigns need to move off government websites and onto the social media platforms that young people actually use.
What You Need to Do Right Now
If you're looking for a place to cool off this summer, change your plans. Avoid the Potomac entirely unless you are on a properly registered watercraft wearing a certified life jacket.
- Skip the river trails for swimming: Do not wade into the water at Great Falls, Mather Gorge, or Scott's Run, even just to dip your toes in. A single slick rock can slide you into a current you can't escape.
- Use municipal alternatives: Head to Montgomery County’s public outdoor pools like the ones in Bethesda, Germantown, or Wheaton. They have lifeguards, treated water, and zero hidden hydraulic undertows.
- Spread the word: If you see friends planning a "cliff jumping" or swimming trip to the Potomac on social media, warn them.
New rules won't patrol the shoreline. True safety comes down to individual choices and understanding that the Potomac River doesn't give second chances.
