Hundreds of terrified children were airlifted to safety by Black Hawk military helicopters as raging floodwaters engulfed a summer camp in Missouri.

Torrential rain unleashed what forecasters have described as a once-in-a-millennium flooding event which swallowed roads and structures.

As the waters continued to rise on Friday, there were fears of a repeat of last summer’s devastating Camp  Mystic tragedy in Texas – where 25 campers, two counselors and the camp’s executive director lost their lives.

This time the  unfolding emergency centered on Camp Taum Sauk in Reynolds County, where surging floodwaters from the Black River trapped hundreds of campers and staff after roads into the remote camp disappeared beneath fast-moving water.

By Friday afternoon, the Missouri Army National Guard had launched Black Hawk helicopters to evacuate approximately 200 campers and counselors, ferrying them to a nearby elementary school where relieved parents finally embraced their children.

Jennifer Box, whose two sons were attending Camp Taum Sauk, said the first reports of flash flooding immediately made her think of the Camp Mystic disaster.

‘It was very harrowing,’ Box said to the New York Times after receiving an email Friday morning confirming the children had been moved to higher ground as a precaution.

‘We knew they were safe, but we didn’t know how to get to them, and that’s kind of your worst nightmare.’

As rain pounded the Ozarks overnight, camp staff sprang into action.

Around 2am Friday, dozens of girls sleeping in low-lying cabins near the river were awakened and evacuated to the camp cafeteria.

But as floodwaters continued rising and began creeping toward that building as well, campers were forced to move again, this time to higher ground near the camp’s tennis courts.

The girls passed the frightening hours making friendship bracelets, playing board games and working on arts and crafts while waiting to be rescued.

Meanwhile, boys housed on higher ground remained in their cabins, listening to the radio and talking while staff monitored the rapidly deteriorating situation.

Outside the camp, frantic parents exchanged scraps of information through group messages as roads became impassable and floodwaters continued to rise.

The emergency unfolded after powerful thunderstorms repeatedly tracked across the same region on Thursday night, dumping extraordinary amounts of rainfall.

Meteorologists refer to the phenomenon as ‘training,’ where storm cells repeatedly move over the same area like railcars traveling along a track.

Lead National Weather Service meteorologist Matt Beitscher said locations across southern Missouri received between six and more than 12 inches of rain, with the heaviest totals falling around Reynolds County.

‘That was probably where the worst of it was,’ Beitscher said.

Shortly before midnight, flash flood warnings were issued for Reynolds County and neighboring Iron County.

By 4am Friday, the National Weather Service escalated the danger to its highest warning level, issuing a Flash Flood Emergency.

‘This is a particularly dangerous situation,’ the warning stated. ‘Seek higher ground now!’

The National Weather Service later described the deluge as a once-in-a-thousand-years rainfall event.

State officials rapidly mobilized emergency resources.

Governor Mike Kehoe declared a state of emergency and activated the Missouri National Guard along with specialized search-and-rescue teams as floodwaters trapped residents across multiple counties.

Late Friday, Kehoe said hundreds of people had been rescued from floodwaters, rooftops, trees and stranded vehicles.

‘As recovery efforts continue and additional rain is expected, I urge everyone in flood-prone and low-lying areas to stay weather-aware, have multiple ways of receiving alerts, and be ready to take protective action,’ the governor said.

Authorities warned the Black River was expected to crest above 28 feet near Annapolis, a level forecast to break previous records.

The flooding extended far beyond Camp Taum Sauk.

At the Bearcat Getaway Campground near the Black River, campers climbed onto the roof of a building to escape the rising water, but the structure eventually collapsed beneath them.

‘Between the weight and the constant waters underneath it, it just gave away on them,’ Missouri Highway Patrol Sgt. Eddie Young said.

Elsewhere in Reynolds County, three people stranded in trees above the raging Black River had to be rescued by emergency crews.

Two rescue boats also capsized in the floodwaters, although all first responders were safely recovered, according to the Reynolds County Sheriff’s Office.

The disaster also turned deadly. Authorities confirmed Saturday that Faith Gregory, who had gone missing after floodwaters ripped her home from its foundation in Crawford County, had been found dead.

Volunteers discovered her body roughly 1.8 miles downstream from her home in Huzzah Creek.

‘This is not the outcome that any of us were hoping for,’ the Crawford County Sheriff’s Office said. 

‘Our thoughts and prayers are with Faith’s family, friends, and all those affected by this tragic loss.’

Officials said no one else remained unaccounted for in the county.

Even after the frightening evacuation, many of the children viewed the helicopter rescue as an unforgettable adventure.

‘When I first heard we were getting on helicopters, I was kind of scared,’ said Everett Box, 11, attending Camp Taum Sauk for his third summer.

‘Then I kind of warmed up to it and was super excited to go on it.’

Fellow camper Cate Hensley, also 11, said the transformation of the landscape was almost impossible to comprehend.

On Thursday she said the Black River was barely visible from her cabin.

By Friday morning, she could no longer tell where the river ended and the road began.

Her cabin was left covered in broken glass, preventing her from retrieving her belongings.

Despite everything that happened, Cate’s mother, Melissa Hensley, said the frightening ordeal had not changed how her family viewed the camp.

‘This is their happy place,’ she said. ‘They plan for this every single year.’

Camp Taum Sauk later thanked the emergency responders who carried out the dramatic airlift, writing on Instagram: ‘We are beyond thankful for your help keeping our camp community safe.’
