More than 850 people have been rescued by emergency responders. Many of the stories have been astonishing: A Coast Guard swimmer saved 165 people at the summer camp; a 22-year-old woman was rescued after being swept 20 miles downriver and clinging to a tree overnight; and a young girl was found after floating on a mattress for hours.

A July Fourth weekend deluge in Texas caused catastrophic flash flooding that has killed more than 80 people. Camp Mystic in Kerr County says Monday morning that it is “grieving the loss” of 27 campers and counselors as the search continues for victims of the disaster.
