Five family members were killed after a flash flood swept through canyons of southern Utah on Friday, July 17, 2026, according to the Wayne County Sheriff's Office (The Guardian).

A flash flood is a flood that happens very quickly, sometimes in just minutes, when a large amount of water rushes through a narrow area. The family had arrived at Sunglow campground, about two miles east of Bicknell, Utah, for a day trip on the day of the flood (St. George News). The Wayne County Sheriff's Office stated it is believed the family fell victim to flooding caused by heavy rains (The Guardian).

Deputies were called to Sunglow campground on Friday night after the body of a young man was found in the flood wash. The bodies of the other four family members were recovered later on Friday and Saturday (The Guardian). The Wayne County Sheriff's Office, led by Sheriff M.A. Gulley and headquartered at 18 South Main Street in Loa, Utah, issued a formal news release about the incident (St. George News; Wayne County).

The Provo fire department confirmed on social media that Fire Captain Spencer Long and his family members were killed. His wife, Katrina Long, co-founder of Summit Medical Spa, and their three sons, Reid, Thayne, and Gage, were the five victims. A daughter of the family survived because she was not on the trip (The Guardian).

The Wayne County Sheriff's Office has not officially released the identities of the victims, according to an earlier report from the Moab Sun News (Moab Sun News). The Provo fire department's social media confirmation, as reported by The Guardian on July 19, appears to be the earliest public identification.

The Associated Press published a wire report on approximately July 19, 2026, confirming that five family members were found dead after a flash flood in a scenic Utah canyon, attributing the information to authorities. The report was syndicated by multiple outlets, including U.S. News & World Report, The Daily Reflector, and KVUE, the ABC affiliate in Austin, Texas (U.S. News & World Report; The Daily Reflector).

The toll rose gradually as the search progressed. ABC4 Utah (KTVX) reported on Facebook on July 18, citing the Wayne County Sheriff's Office, that three family members had been found dead in the Sunglow Campground area. That number subsequently increased to five as recovery efforts continued (ABC4 Utah / Facebook).

A GoFundMe site was set up by family friend Bree Nielson to support the Longs' surviving daughter (The Guardian).

Wayne County, a sparsely populated region in south-central Utah, sits adjacent to Capitol Reef National Park. Its canyon topography makes the area particularly susceptible to flash flooding. When intense rainfall hits the region's smooth rock surfaces, water channels rapidly into narrow slot canyons and washes with little warning. Sunglow campground, near the town of Bicknell, lies within this terrain. The monsoon season in the Colorado Plateau region typically runs from July through September, bringing thunderstorms capable of dumping large amounts of rain in short intervals. When those storms align with vulnerable canyon geography, the results can turn fatal within minutes.

The broader context here is that southern Utah's canyon country has a well-documented history of flash flood fatalities, particularly in slot canyons where escape routes are limited or nonexistent. The risk is not merely a matter of rainfall volume at the point of impact. Flash floods in canyons can be triggered by storms miles upstream, with victims receiving no direct precipitation at their location. Imagine a water slide at a pool: someone pours a bucket of water at the top, and seconds later a rush of water hits the bottom, even though the people at the bottom never saw the bucket. That is how canyon flash flooding works, and it is what makes it so deadly and so hard to prepare for, even for experienced outdoor users.

The Long family's case fits this pattern with grim precision. They had traveled to Sunglow campground for a day excursion, presumably unaware of upstream conditions that would send floodwaters through the wash. Spencer Long, as a fire captain with the Provo fire department, would have had professional familiarity with emergency response, which underscores the speed and severity with which canyon flash floods can overwhelm even those with first responder training.

The recovery operation, spanning Friday night into Saturday, required Wayne County deputies to navigate the same hazardous terrain that claimed the victims. The incremental discovery of bodies, first one young man found in the flood wash on Friday night, then four more recovered over the following day, reflects the logistical challenges of search operations in canyon environments where flood debris can scatter remains across considerable distances.
