Safety resources

RVA James uses these official sources to ground its recommendations. Always defer to your own judgment and these authorities over any AI-generated guidance.

Water & swimming safety

  • American Academy of Pediatrics (AAP)

    Drowning prevention guidelines, minimum swimming age recommendations, and life jacket requirements by age. The basis for our swim threshold rules.

    AAP water safety guidelines →

  • U.S. Coast Guard (USCG)

    Life jacket requirements, paddlesport regulations, and boating safety. All children under 13 are required to wear a USCG-approved PFD on or near the water.

River conditions

  • USGS Gage 02037500 — James River at Richmond

    Real-time gage height and discharge for the James River at Richmond. Updated every 15 minutes. This is the primary data source for our river level readings.

  • NWS Wakefield — Flood forecasts

    Official flood watches, warnings, and advisories for the Richmond area. Call 911 or check here in any emergency.

Water quality

  • James River Association — James River Watch

    E. coli monitoring and swim safety advisories. We use the Virginia DEQ standard of 235 CFU/100 mL as our swim-safe threshold.

  • Richmond DPU — CSO Advisories

    Combined sewer overflow notifications. After heavy rain, sewer overflows increase bacterial levels. We recommend no swimming for 48 hours after any active CSO advisory.

Combined Sewer Overflows in Richmond

Richmond’s combined sewer system carries both sewage and stormwater in the same underground pipes. On most days, everything flows to the treatment plant as intended. After heavy rain, however, the volume can overwhelm the plant’s capacity — and the overflow valves open, releasing a mix of untreated sewage and stormwater directly into the James River to prevent backups into streets and basements. This is a combined sewer overflow, or CSO.

The combined system covers much of downtown Richmond, running along the same stretch of the James where most of the popular river access points are — Brown’s Island, Belle Isle, the Manchester Climbing Wall, and others. After significant rain (typically anything over half an inch in a few hours), overflows at multiple outfalls are common. The monitoring data on this site comes from Richmond DPU’s EmNet real-time monitoring system, which tracks each outfall’s active discharge status.

Bacterial levels in the James — particularly E. coli and enterococcus — spike after a CSO event and take time to return to safe levels. Richmond DPU and the James River Association both recommend avoiding water contact for at least 48 hours after a known overflow. That’s why this site shows an advisory window extending 48 hours from the most recent observed discharge, even if the overflow has already stopped. When a site is still actively discharging, the window keeps extending so it always reflects the full expected recovery time.

Upstream dam hazards (Z-Dam, Williams Island, Bosher’s)

Three low-head dams sit on the James River upstream of downtown Richmond. Each one has killed people. They look harmless from the water above — the surface is glassy, the drop is small, the current looks normal. That look is the hazard.

How they kill.Water flowing over a low-head dam dives at the base, recirculates upstream along the riverbed, and comes back up at the boil zone. Anything floating in that loop — a boat, a swimmer, a paddler in a PFD — gets pulled back under the falling water, resurfaces in the boil zone, and gets pulled under again. The hydraulic is sometimes called a “drowning machine.” PFDs do not break the cycle. Civil engineers estimate around 50 deaths a year nationally across the country’s ~10,000 low-head dams.

  • Z-Dam (south channel, west of Pony Pasture)

    The deadliest single feature on the James in Richmond. JRPS says it “alone” is responsible for many drownings. Built 1932, modified 1993 for fish passage. The hazard increases at higher water — at moderate flows the dam crest becomes nearly invisible from upstream, which is the drowning-machine pattern at its most dangerous.

  • Williams Island Dam (north channel)

    7-foot gravity dam built 1905 to divert City drinking water. Same hydraulic as Z-Dam. The north channel is often described as “more peaceful and calm” than the south — that calm appearance is exactly the deceptive surface the drowning-machine warning describes. News coverage often combines Williams Island Dam and Z-Dam death counts; the area is treated as a single threat zone.

  • Bosher’s Dam (~1 mile upstream of Williams Island)

    12-foot stone low-head dam from the mid-1800s, between Tuckahoe and west Richmond just upstream of the Edward E. Willey Bridge. The 1999 fish ladder helps shad, herring, and striped bass — it doesn’t reduce the dam’s recreation hazard.

If you paddle upstream of downtown, know where these dams are before you put in. Huguenot Flatwater is upstream of Z-Dam and Williams Island Dam, so a drift-down failure mode is real if you lose your boat. Riverside paths along Pony Pasture and Buttermilk Trail give a shore view — the water below the dam often looks like a normal riffle, which is part of the problem.
