HORRIFYING new pictures have captured the devastation left behind after a freak “1-in-1,000-year” downpour unleashed deadly flash floods.

Black Hawk crews plucked more than 200 stranded campers and counselors to safety as roads vanished beneath raging water, while a young woman was swept from her collapsing home.

The disaster struck southeastern Missouri after up to 12.5 inches of rain fell in less than 24 hours across several communities

Eight Missouri Army National Guard UH-60 Black Hawk helicopters were deployed to Camp Taum Sauk in Reynolds County after floodwaters cut off its escape routes.

Crews airlifted 202 young campers and staff members to a nearby elementary school, where they were reunited with their families.

“Thank you National Guard, Reynolds County 911 emergency responders … we are beyond thankful for your help keeping our camp community safe,” the camp said in a social media post.

At least 350 people had been pulled to safety across the region by Saturday afternoon as rescuers searched flooded homes, campgrounds and vehicles.

Reynolds County crews alone carried out around 90 water rescues involving residents, motorists and vacationers.

Emergency teams were also called to a reported building collapse at Bearcat Getaway Campground.

As many as 17 people were initially feared to have entered the floodwater, but officials later said everyone linked to the collapse had been rescued or accounted for.

Five campers reported missing at the campground were found safe, while around 10 people were rescued from the roof of the Black River Lodge.

But the flooding turned deadly in nearby Crawford County, where 23-year-old Faith Gregory was swept away early Friday.

Rising water from Huzzah Creek caused a wall of the home she shared with her boyfriend, Logan Ousley, to collapse at around 3:30am.

The couple and their four dogs managed to climb into a green-and-tan kayak as the property was overwhelmed.

Ousley escaped the torrent, but Gregory and the dogs were carried away by the fast-moving water.

One dog was later found alive around eight miles from the house, while the other three remained missing as of Saturday.

Volunteers discovered Gregory’s body in Huzzah Creek at approximately 11:30am Saturday, about 1.8 miles downstream from her home.

Missouri State Highway Patrol officers, firefighters, sheriff’s deputies and the county coroner helped recover her body.

“God answered our prayers today by allowing us to find Faith,” a family fundraiser said.

“Although it was not the outcome we wanted we found her. So many people have prayed and searched for this sweet girl.”

The family said Gregory had lived for years in Davisville and loved her local community.

Crawford County Sheriff Darin Layman thanked the volunteers and first responders who worked for hours in hazardous conditions.

Some communities recorded between seven and 12.5 inches of rain, with more than a foot falling in isolated areas overnight.

Meteorologists described the localized deluge as at least a one-in-1,000-year rainfall event, one with a 0.1 percent chance of occurring in any given year under a normal conditions.

The National Weather Service issued its highest-level flash flood warning for more than 4,000 people in parts of Reynolds and Iron counties.

Missouri Governor Mike Kehoe declared a state of emergency as crews carried out multiple swift-water rescues.

“Activating the State Emergency Operations Plan allows our agencies to move quickly, coordinate resources, and support local response efforts,” Kehoe said.

“I’m grateful for every first responder and local team member working around the clock to help save lives.”

The American Red Cross opened an emergency shelter at First Baptist Church in Centerville for residents forced from their homes.

Further showers were forecast through the weekend, threatening to slow the receding water and complicate rescue and recovery efforts.
