Three days after cataclysmic floods tore through a stretch of the Texas Hill Country, officials have confirmed the deaths of 27 children and counselors who had been missing from a girls’ summer camp.

The stunning flood that killed more than two dozen campers and counselors along a river at Camp Mystic in the Texas Hill Country was the result of extraordinary rain and walls of water. Nonetheless, experts agree that information about how a camp plans for emergencies is just as important as the lunch menu and the times to go swimming.

The number of dead from the devastating floods across central Texas surpassed 100 as dozens of people remain missing. In Kerr County, at least 84 people died, including 28 children, according to officials.
