A man who became separated from his tubing group on the Green River near Whitney Bridge in unincorporated King County spent hours stranded on a rock in the dark before rescuers pulled him out around 1:20 a.m. Wednesday into Wednesday night's early hours turned Thursday morning. Emergency crews were dispatched around 10:47 p.m. Wednesday after the tubing group reported one person missing, kicking off a search that stretched nearly two and a half hours through pitch-black water and steep river terrain.
According to KOMO News, Mountain View Fire & Rescue provided details on the response, which drew personnel from a striking number of regional agencies: Puget Sound Regional Fire Authority, Valley Regional Fire Authority, Enumclaw Fire Department, Renton Regional Fire Authority, Skyway Fire, South King Fire, King County Medic One, and the King County Sheriff's Office. Rescuers launched kayaks both upstream and downstream of the last known location while firefighters navigated the moving river in complete darkness, coordinating the search across water, ground, and air.
The King County Sheriff's Office used cell phone location data to help narrow down the search area, then flew a drone equipped with forward-looking infrared technology to scan the riverbanks for a heat signature in the dark. That combination of tools eventually led rescue crews to the man, whom they found stranded on a rock in the river. He was brought to the Whitney Bridge boat launch, where King County Medic One evaluated him and released him at the scene.
A Popular but Risky Stretch of River After Dark
The Whitney Bridge boat launch marks the end of a float route that's become a summer staple for Green River tubers, who commonly put in at Flaming Geyser State Park for a roughly 45-minute drift downstream, according to Ten Trails. That stretch, and the river more broadly, has seen repeated tragedy this summer. On July 4, a 31-year-old Seattle man drowned after going swimming at Flaming Geyser State Park; a bystander pulled him from 15 feet of water, but he died two days later at Harborview Medical Center, per KING 5. Less than three weeks later, on July 18, emergency crews responded to another water rescue in the Green River Gorge where a victim died at the scene, as reported by the Auburn Examiner.
Fire officials advised that people who become stranded should stay in one location if it's safe to do so, since staying put improves the chances of being found quickly. Officials also recommended wearing a properly fitted U.S. Coast Guard-approved life jacket, a reminder that carries legal weight in unincorporated King County. Under King County Ordinance 17124, enacted in June 2011, anyone swimming, floating, or boating on major rivers in unincorporated parts of the county is legally required to wear a personal flotation device, with repeat violators facing fines under county code, according to the Snoqualmie Valley Record.
Cold Water and a Countywide Drowning Trend
Regional health officials have cautioned that summer rivers in King County remain dangerously cold due to mountain snowmelt, which can trigger sudden cold-water shock and muscle incapacitation within minutes, even for experienced swimmers, per Seattle's Child. That risk has played out in the county's broader numbers. King County recorded 190 preventable drowning deaths between 2018 and 2024, averaging more than 27 deaths a year, compared to about 18 annually from 2014 through 2017, the Auburn Examiner reported, citing county health officials who noted that over 60 percent of drowning victims had drugs or alcohol in their system.
Preliminary 2024 data showed 25 preventable drowning deaths countywide, down from 30 the year before, with more than half occurring in open water such as rivers, lakes, and Puget Sound, according to King County. Officials have urged caution even during warm weather, noting that open water stays dangerously cold regardless of air temperature. The King County Sheriff's Office Air Support Unit, which deployed the thermal drone in this rescue, regularly uses the small uncrewed aircraft to supplement its Guardian 1 helicopter during nighttime searches.
Mountain View Fire & Rescue, formally King County Fire Protection District No. 44, covers roughly 70 square miles of unincorporated South King County, including Black Diamond and the Green River corridor, and frequently leads swiftwater search operations alongside partner agencies. It remains unclear whether the tubing group involved Wednesday night carried safety gear or lights, or whether alcohol played any role in the incident.
