In KERRVILLE, Texas, concerned parents took to social media to desperately share pictures of their daughters while searching for information, as at least 23 young campers from an all-girls camp went missing after severe floods swept through central Texas overnight.

The torrential storm claimed at least 27 lives, including nine children, after dumping nearly 12 inches of rain before dawn on Friday, causing the Guadalupe River to overflow in the historic summer camp region. Many individuals are still unaccounted for, but authorities have reported rescuing approximately 850 people thus far.

State officials said 23 to 25 girls from Camp Mystic, a riverside Christian camp in Hunt, Texas, still were unaccounted for.

“I’m asking the people of Texas, do some serious praying,” Lt. Gov. Dan Patrick said. “On-your-knees kind of praying that we find these young girls.”

Flood turns storied Camp Mystic into a nightmare

The camp, which opened its doors in 1926, gained such immense popularity over the years that these days families are advised to join a waiting list for potential campers years ahead of time.

Photos and videos taken before the flood are idyllic, showing large cabins with green-shingled roofs and names like “Wiggle Inn,” tucked among sturdy oak and cypress trees that grow on the banks of the Guadalupe River. In some social media posts, girls are fishing, riding horses, playing kickball or performing choreographed dance routines in matching T-shirts. Girls ranging in age from 8 to 17 years old pose for the camera with big smiles, arms draped across the shoulders of their fellow campers.

But the floodwaters left behind a starkly different landscape: A pickup truck is balanced precariously on two wheels, its side lodged halfway up a tree. A wall is torn entirely off one building, the interior empty except for a Texas flag and paintings hung high along one side. A twisted bit of metal – perhaps a bedframe – is stacked next to colorful steamer trunks and broken tree limbs.

First responders are scouring the riverbanks in hopes of finding survivors. Social media posts are now focused on the faces of the missing.

Rescuers evacuate some campers by helicopter

By Friday afternoon, Texas Game Wardens had arrived at Camp Mystic and were evacuating campers. A rope was tied so girls could hang on as they walked across a bridge, the floodwaters rushing around their knees.

Elinor Lester, 13, said she was evacuated with her cabinmates by helicopter after wading through floodwaters. She recalled startling awake around 1:30 a.m. as thunder crackled and water pelted the cabin windows.

Lester was among the older girls housed on elevated ground known as Senior Hill. Cabins housing the younger campers, who can start attending at age 8, are situated along the riverbanks and were the first to flood, she said.

“The camp was completely destroyed,” she said. “It was really scary.”

Her mother, Elizabeth Lester, said her son was nearby at Camp La Junta and also escaped. A counselor there woke up to find water rising in the cabin, opened a window and helped the boys swim out. Camp La Junta and nearby Camp Waldemar said in Instagram posts that all campers and staff were safe.

Among those confirmed dead was the director of another camp just up the road from Camp Mystic.

Elizabeth Lester sobbed when she saw her daughter, who was clutching a small teddy bear and a book.

“My kids are safe, but knowing others are still missing is just eating me alive,” she said.

Families of missing campers worry

Dozens of families shared in local Facebook groups that they received devastating phone calls from safety officials informing them that their daughters had not yet been located among the washed-away camp cabins and downed trees.

Camp Mystic said in an email to parents of the roughly 750 campers that if they have not been contacted directly, their child is accounted for.

On Friday afternoon, more than a hundred people gathered at an Ingram elementary school that was being used as a reunification center, watching for the faces of loved ones as buses full of evacuees arrived. One young girl wearing a Camp Mystic T-shirt stood in a puddle in her white socks, sobbing in her mother’s arms.

Camp Mystic sits on a strip known to locals as “flash flood alley.”

“When it rains, water doesn’t soak into the soil,” said Austin Dickson, CEO of the Community Foundation of the Texas Hill Country, which was collecting donations. “It rushes down the hill.”

State officials began warning of potential deadly weather a day earlier. The National Weather Service had predicted 3 to 6 inches of rain in the hilly region northwest of San Antonio, but 10 inches fell. The Guadalupe River rose to 26 feet within about 45 minutes in the early morning hours, submerging its flood gauge, Patrick said.

Decades prior, floodwaters engulfed a bus of teenage campers from another Christian camp along the Guadalupe River during devastating summer storms in 1987. A total of 10 campers from Pot O’ Gold Christian camp drowned after their bus was unable to evacuate in time from a site near Comfort, 33 miles (53 kilometers) east of Hunt.

Happy camp memories are now tinged with grief

Chloe Crane, a teacher and former Camp Mystic counselor, said her heart broke when a fellow teacher shared an email from the camp about the missing girls.

“To be quite honest, I cried because Mystic is such a special place, and I just couldn’t imagine the terror that I would feel as a counselor to experience that for myself and for 15 little girls that I’m taking care of,” she said. “And it’s also just sadness, like the camp has been there forever and cabins literally got washed away.”

Crane said the camp is a haven for young girls looking to gain confidence and independence. She recalled happy memories teaching her campers about journalism, making crafts and competing in a camp-wide canoe race at the end of each summer. Now for many campers and counselors, their happy place has turned into a horror story, she said.
