Amid the devastating aftermath of a flood that claimed the lives of at least 13 individuals and obliterated a Christian girls’ summer camp in Texas, concerned families are anxiously awaiting updates on the well-being of the nearly two dozen missing girls.

The catastrophe occurred when the Guadalupe River in Kerr County overflowed due to relentless downpours, causing severe damage to cabins and structures at Camp Mystic overnight from Thursday to Friday, leading to the disappearance of around 23 girls.

Although most camp attendees, aged between 7 and 17, were safely evacuated as floodwaters surged, a few children were unable to escape in time and are currently unaccounted for in the surging currents.

The Guadalupe River — on which Camp Mystic is perched in the San Antonio suburb of Hunt — rose more than 20 feet in just 90 minutes, the National Weather Service reported, a level of flooding the area hasn’t seen since 1987 and forced evacuations throughout the region.

At least 13 people have been killed in Kerr County as of Friday, though it remains unclear if any were the missing girls.

After Camp Mystic advised parents that if they haven’t been directly contacted to assume their daughters are accounted for and safe, officials cautioned parents not to assume the worst.

“That does not mean they’ve been lost. They could be in a tree. They could be out of communication,” Texas Lt. Gov. Dan Patrick said at a press conference. “We’re praying for all those missing to be found alive.”

Below are the Camp Mystic girls who have confirmed missing so far:
