Before the floods came, Camp Mystic’s sprawling 700-acre campground was dotted with green-roofed, cobblestone cabins and rows of cypress, live oak and pecan trees. After, bed sheets tangled in broken branches. Muddy clothes, an overturned canoe and other belongings from campers remained.

As hope for finding survivors dims, questions swirl around whether Camp Mystic's emergency plan was adequate. Texas doesn't approve or keep copies of such plans; camps are required to show only that they have plans in place.
