Woman Airlifted After CPR at Acton's NARA Park Pond, Days After Lifeguards Left

A large emergency response converged on NARA Park in Acton Friday afternoon after medics were seen performing CPR on a woman at the pond, which residents describe as the town's most popular swimming spot. She was ultimately transported by helicopter, and the response unfolded just five days after the park's lifeguard-supervised beach season had officially ended for the year.

Emergency responders arrived at NARA Park around 2 p.m., according to Boston 25 News, which first reported the incident. A photographer for the station observed medics performing CPR on the woman before she was flown from the scene by helicopter. The outlet, whose report was authored by Michael Raimondi, said it had reached out to the Acton Police Department, the Acton Fire Department, and the Middlesex District Attorney's Office for more information, and that the story remained developing as of Friday evening.

The air transport almost certainly involved Boston MedFlight, which keeps its primary base at Hanscom Field in nearby Bedford — roughly 10 miles southeast of NARA Park. Each of the service's air missions is staffed by a critical care nurse and a critical care paramedic capable of delivering ICU-level care in transit, giving Acton rapid access to advanced medical resources following CPR efforts on the ground.

A Pond Without Lifeguards

What makes the timing of Friday's response notable is that it came after the pond's supervised swim season had already wrapped up. Town of Acton Recreation Department guidelines show that the official 2026 lifeguard-supervised beach season at NARA Park ended on Sunday, August 23 — lifeguard coverage had run only from 10 a.m. to 5:30 p.m. daily during the summer season. That means the pond, which residents told Boston 25 News is the most popular swimming area in town, had been operating for five days without official supervision by the time emergency crews were called.

Municipal park regulations still restrict swimming to designated beach areas, prohibit flotation devices other than U.S. Coast Guard-approved life jackets, and require dogs to remain leashed and off the beach at all times, regardless of whether lifeguards are on duty. Once the season ends, though, safety at the pond effectively shifts onto bystanders and first responders rather than trained lifeguard staff.

Not the Park's First Water Emergency

Friday's incident is not the first time Acton first responders have had to conduct a water rescue at NARA Park. In December 2024, fire and police crews responded after five members of a film crew fell through thin ice on the pond, according to The Acton Exchange. All five were rescued, hospitalized for cold exposure, and recovered.

NARA Park itself — officially the Nathaniel Allen Recreation Area — is a 40-acre municipal facility at 25 Ledge Rock Way that first opened in 1999, per the Town of Acton. It was originally called the North Acton Recreation Area before town meeting voters renamed it in 2012 to honor Nathaniel Allen, a Civil War veteran and Acton's only recipient of the Medal of Honor. Beyond its beach, the park's grounds include sports fields, walking trails, and an amphitheater that drew several hundred residents for a memorial vigil organized by local clergy earlier this month, on August 19, as reported by the Acton Exchange.

Late Summer Is the Riskiest Stretch for Drownings

The timing of Friday's response also lines up with a broader statewide pattern. Massachusetts Department of Public Health data recorded 57 unintentional drowning deaths and 86 non-fatal near-drowning hospitalizations across the Commonwealth in 2022, and state officials have noted that drowning fatalities consistently peak during the late-summer months of July and August, according to Mass.gov.

Public health data compiled by the CDC and the state health department also shows that while children under 5 face the highest drowning risk in swimming pools, older adolescents and adults are statistically far more likely to drown in open bodies of water like ponds, lakes, and rivers, as reported by Patch. Natural bodies of water carry hazards such as sudden depth drop-offs and reduced visibility that pools don't typically present. Even so, Massachusetts maintains an age-adjusted unintentional drowning rate of 0.83 deaths per 100,000 residents, lower than the national average of 1.31 per 100,000, per federal CDC data spanning 2018 through 2021.

The Acton Police Department is currently led by Chief Douglas Sturniolo, who was formally sworn in this past July after serving as deputy chief, following the retirement of 42-year veteran Chief James Cogan, according to a Town of Acton press release. It remains unclear whether the department, the fire department, or the district attorney's office plans to issue any updated guidance on off-season access to the pond. The woman's current medical condition and the precise circumstances that led to her distress have not been publicly disclosed, and this story will be updated as more information becomes available.
