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.

Despite officials urging civilians to stay away, volunteers have joined the search for missing people and the cleanup on the Guadalupe River.

Six counties reported deaths from multiple severe flood events since Friday, July 4. Also, Kerrville officials reported that a privately owned drone collided with a helicopter conducting search and rescue operations.

It took just 90 minutes for the river to rise more than 30 feet. A look at the historic flood levels now etched into Central Texas history.
